Background and Purpose Chronic stress affects many physiological functions in the body leading to number of disorders including diabetes. Hence present work was designed to study Ethanolic extract of Cassia occidentalis linn. leaves (ECO) for its hypoglycaemic effect and role of 5-HT1A receptor in chronic stressed rat. Experimental Approach Animals divided in 5 groups (n=6) and treated with 500 mg/kg p.o. of ECO alone and in combination with Aripiprazole 2.5mg/kg, i.p. (ECO+ ARI group) and WAY 100635 (0.3mg/kg, i.p.) (ECO+WAY group) for 28 days to assess its effect in immobilized stressed rats. Open field and Hole board test were used for determination of stress in animals followed by blood glucose level and adrenal gland study. Key Results Animals treated with ECO 500 mg/kg p.o. and ECO+ ARI showed significant (p<0.01) stress resistant activity as compared to negative control. Whereas ECO+WAY treated group showed no significant change in stress related behaviour compared to negative control. Results also demonstrated that there was significant (p<0.01) decrease in blood glucose level and weight of adrenal gland in animals treated with ECO and ECO+ ARI. Whereas, ECO+WAY group showed non-significant change in blood glucose level and weight of adrenal gland as compared to negative control. Conclusion and Implications Present study concludes, ECO possess antistress and hypoglycaemic activity in immobilized stressed rats by activating 5-HT1A receptor.

Theoretical elucidation of the turn-off mechanism of the luminescence of a chemosensor based on a metal-organic framework (MOF) [Zn2(OBA)4(BYP)2] (BYP: 4,4’-bipyridine; H2OBA: 4,4’-oxybis(benzoic acid)), selective to nitrobenzene via quantum chemical computations is presented. The electronic structure and optical properties of Zn-MOF were investigated through the combination of density functional theory (DFT) and time-dependent-DFT methods. Our results indicate that the fluorescence emission is governed by a linker (BPY) to linker (OBA) charge transfer (LLCT) involving orbitals π-type. Next, interaction with the analyte was analyzed, where very interesting results were obtained, i.e. the LUMO is now composed by orbitals from nitrobenzene, which changes the emissive state of the Zn-MOF. This fact suggests that the LLCT process is blocked, inducing then the fluorescence quenching. Otherwise, the Morokuma-Ziegler energy decomposition and NOCV (Natural Orbitals for Chemical Valence) on the Zn-MOF-nitrobenzene interactions were studied in detail, which illustrate the possible channels of charge transfer between Zn-MOF and nitrobenzene. Finally, we believe that this proposed methodology can be applied to different chemosensor-analyte systems to evidence the molecular and electronic factors that govern the sensing mechanisms.

Tree canopies provide habitats for diverse and until now, still poorly characterised communities of microbial eukaryotes. One of the most general patterns in community ecology is the increase in species richness with increasing habitat diversity. Thus, environmental heterogeneity of tree canopies should be an important factor governing community structure and diversity in this subsystem of forest ecosystems. Nevertheless, it is unknown if similar patterns are reflected at the microbial scale within unicellular eukaryotes (protists). In this study, high-throughput sequencing of two prominent protistan taxa, Cercozoa and Oomycota, was performed. For a comprehensive assessment of their diversity across all ecological compartments from forest soils to the canopy, group specific primers were used. When taking OTU abundances into account, our results showed highly dissimilar protistan communities within the investigated microhabitats. We observed no pattern of nestedness, because the majority of OTUs was present in all sampled microhabitats. According to the microbiological tenet ‘Everything is everywhere, but, the environment selects’, habitat diversity strongly favoured distinct protistan taxa in terms of abundance, but due to their almost ubiquitous distribution the effect of species richness on community composition was negligible.

In principle, populations with higher genetic diversity and larger effective sizes have greater evolutionary capacity (i.e., higher adaptive potential) to respond to ecological stressors. Small isolated populations tend to lose genetic diversity rapidly due to the detrimental effects of drift and inbreeding via genetic erosion. We are interested in how adaptive potential persists in small populations and how it fluctuates relative to overall genomic diversity. We analyzed individual whole genome sequences from different populations of Montezuma Quail (Cyrtonyx montezumae), a small ground-dwelling bird that is sustainably harvested in some portions of its range but is of conservation concern elsewhere. Our results indicate that overall, Montezuma Quail populations in the U.S. exhibit low levels of genomic diversity due in large part to long-term declines in effective population sizes over nearly a million years. The smaller and more isolated Texas population is significantly more inbred than the large Arizona and the intermediate-sized New Mexico populations. The Texas gene pool has a significantly lower proportion of deleterious alleles than the Arizona gene pool, but also significantly more high-frequency deleterious alleles that, coupled with elevated inbreeding, elevate the realized genetic load in Texas. Our results highlight that smaller, isolated populations are at higher risk of inbreeding depression as detrimental mutations rise in frequency due to drift and weakened purifying selection. Our study illustrates how population genomics can be used to proactively assess both neutral and adaptive aspects of contemporary genetic diversity in a conservation framework while simultaneously considering deeper demographic histories.

Ecological theory postulates that the niche of co-occurring species must differ along some ecological dimensions in order to allow their stable coexistence. Yet, many biological systems challenge this competitive exclusion principle. For instance, insectivorous bats from the Northern Hemisphere typically form local assemblages of multiple species sharing highly similar functional traits and pertaining to identical feeding guilds. Although their trophic niche can be accessed with unprecedented details using genetic identification of prey, the underlying mechanisms of resource partitioning remain vastly unexplored. Here, we studied the differential diet of three phenotypically and phylogenetically closely-related bat species of the genus Plecotus in an area of sympatry and throughout their entire breeding season (April-October) using DNA metabarcoding. Even at such a small geographic scale, we identified strong seasonal and spatial variation of their trophic niche at both intra- and inter-specific levels. Indeed, while the different bats fed on a distinct array of prey during spring, they showed higher niche overlap during summer and fall, when all three bat species switched their hunting behavior to feed on few temporarily abundant moths. Furthermore, by considering the ecological traits of prey species, we inferred from the menu of each bat species that feeding grounds and hunting techniques differed suggesting that niche partitioning was primarily habitat-driven. As predicted by their phylogenetic relationships, the two most-closely related bat species exhibited the most distinct foraging habitat preferences, while the third, more distantly-related species was more generalist. These results highlight the need of extensive samples to fully understand species coexistence.

A micromechanical model based on the realistic microstructure of carbon fiber reinforced aluminum (CF/Al) composites was developed for the first time. The transverse compressive behaviors, with particular emphasis on damage mechanism of the composites were investigated by numerical simulation and experiment. The results showed that the micromechanical model considering the realistic fiber arrangement predicts the mechanical properties more accurately than that based on an idealized fiber arrangement, and the calculated stress-strain curves agrees well with the experimental ones. The interfacial damage accumulates with compressive strain increasing, and induces the local interface failure successively. The progression and interaction of interface failure and matrix damage dominates the transverse compression process, and leads to the initiation of fiber failure in the ultimate stage, resulting in a fracture surface with the characteristic of interfacial debonding and fiber rupture. Moreover, parametric analysis based on the micromechanics model was carried out to evaluate the influences of interfacial properties and fiber volume fraction on the transverse compressive behavior of the composites.

This paper presents a study on the effect of microstructure on the fatigue crack growth rate (FCGR) in advanced normalised-rolled (NR) and thermomechanical control process (TMCP) S355 steels in the Paris Region of the da/dN vs. ΔK log-log plot. The environments of study were air and seawater (SW), under constant amplitude sinewave fatigue loading. Discussions were based mainly on the comparison between the crack path in the TMCP and NR steels. Fundamentally, three phenomena: crack-tip diversion, crack-front bifurcation and metal crumb formation were observed to influence the rate of fatigue crack growth (FCG). The prevalence of these phenomena appears to be a function of the nature of the material microstructure, environment and crack-tip loading conditions. The three factors appear to retard the crack growth by reducing or re-distributing the effective driving force at the main active crack tip. A crack path containing extensively the three phenomena was observed to offer strong resistance to FCG. Increase in the FCGR was observed with decrease in the crack-tip diversion angle, branched-crack length and metal crumbs formed. In SW, the degree of the electrochemical dissolution of the microplastic zone (or crack-tip blunting) appears to be an additional factor influencing crack growth in ferrite-pearlite (α-P) steel. This study, generally tends to present microstructural features that strongly influenced FCGR in α-P steels in the Paris Region both in air and SW. This work is very important in the design of fatigue resistant steel.

Inadequate access to fresh water during dry winter season is a major limitation in realizing high crop yield. Using available saline water except at germination and crown root initiation stages can be a practical solution to meet water demand. Therefore, a field experiment was conducted in saline soils to investigate the effect of tillage and rice straw mulch on soil properties and its interrelation with yield of rainfed sorghum (RS) and irrigated wheat (IW) uUnder three levels of saline irrigation of 100, 80 and 60% water requirement (WR) of wheat. Reduced (RT), conventional (CT) and zero tillage (ZT) were taken in main plots and saline irrigation (ECiw 8.0 dS m-1) and rice straw mulch (0 and 5 Mg ha-1) in subplots. Zero tillage significantly reduced the wheat yield compared to CT and RT. Interaction between RT, mulching and 60WR markedly increased the sorghum fodder yield. Deficit saline irrigation (60WR) caused a significant reduction in soil salinity (ECe) after every crop cycle. Soil microbial biomass C, N (MBC, MBN), dehydrogenase (DHA), urease (Ur), and alkaline phosphatase (AlP) decreased with increment of ECe. Irrigation with 60WR and ZT maintained higher values of MBN. The α-glucosidase, MBC, ECe, available N, MBC: MBN and Ur were identified as significant contributor towards soil health index (SHI). Deficit saline irrigation (60WR) and ZT showed higher values of SHI. Thus, applying deficit saline water irrigation, RT and mulching is most promising for maintaining high SHI, saving fresh irrigation water without affecting yield of RS-IW cropping system.

The Tibetan Plateau, a vulnerable eco-region for global warming, has huge value of science and practice on ecological restoration to mitigate and adapt to climate change. Sophora moorcroftiana shrubs, which are widely distributed in the middle reaches of Yarlung Zangbo River basin, have been recovered on desertified land benefiting from natural restoration during the past decades. However, the effects of habitat conditions in different topographies on population structure and distribution of S. moorcroftiana have been rarely reported. Here, we achieve the variation of vegetation and micro-topography of S. moorcroftiana population by a series of field surveys with Terrestrial Laser Scanning (TLS) during natural restoration in 2017. The results indicate that the positive correlation between height and CPA reached the 99% confidence level (p < 0.01). The plant height was significantly correlated with the elevation and slope (r = 0.167 and 0.145, respectively; p < 0.01). While the distribution of S. moorcroftiana population decreased along increasing elevation, and the trend of distribution was decreasing firstly, increasing secondly and decreasing finally with increasing slope. The habitat conditions on the southwest slope of approximately 20°-25° with altitudes of 3593-3643 m most favor to the distribution of S. moorcroftiana population in this region. These will help to understand the effect of micro-topography on population structure and distribution of Sophora moorcroftiana in southern Tibetan Plateau and assess the effectiveness of natural restoration of Sophora moorcroftiana in different topographies.

Khejri (Prosopis cineraria) based agroforestry systems i.e. traditional and copied/manipulated from traditional systems were assessed for ecosystem services. The information on different aspects of Khejri and its ecosystem services was collected through several documents on the subject sourced through web and relevant articles of select journals. The authors also visited the traditional Khejri based agroforestry fields in the area and made observations on the ecosystem services provided. The data were collected for provisioning, regulating, supporting, aesthetic and religious services. The Khejri based agroforestry systems were found to provide all ecosystem services. In total, we identified fourteen services provided by Khejri based agroforestry systems. Khejri-based agri-silvicultural and Agri-Silvi-horticultural systems provided more services and profits than sole cropping or other land-use systems in the region. Soil fertility and organic matter were also more under Khejri based agroforestry system as compared to other systems. Khejri based agroforestry systems enhanced the farm income, improved soil fertility, provided nutrition and resilience under hostile climatic conditions without degradation of land and other natural resources. Identification of possible ecosystem services from Khejri based agroforestry systems in our study will provide an instrument to the policymakers for assessing monetary outcomes of Khejri based agroforestry systems.

Background: Fangcang hospital (cabin hospitals) played a key role in isolation and control of the infection sources during COVID-19 epidemic. The patients at Fangcang hospitals were complicated, and many had different symptoms of COVID-19, some had comorbidities or mental stress, and many were confused with the drug usages etc. Objective: Due to the limitation and high work pressure of first line medical workers, patients’ various problems couldn’t be explained well. Under this circumstance, online pharmaceutical care was provided by clinical pharmacists. This study was a retrospective study to evaluate the role and usefulness of clinical pharmacists at Jianghan Fangcang Hospital. Besides, this new mode of service was also introduced in detail to provide options for pharmacists in other hospitals. Methods: The pharmaceutical care included medication education via broadcast station, and medication reconciliation, optimization of drug use, monitor of adverse drug events, and psychological comfort via WeChat® one-to-one service. In this study, we analyzed patients’ characteristics and drug usages, concluded almost 200 patients’ problems classified into 6 aspects solved by clinical pharmacists, and also assessed the patients’ satisfaction with our service. Results: The clinical pharmacist help patients solved almost 200 questions, which mainly focused on the drug related problems including drug usage (65.38%), medication reconciliation (55.13%), drug precautions (23.1%), adverse drug reactions (35.9%), and psychological counseling (32.05%). Through 35 days’ services, Most patients were satisfied with clinical pharmacist service(66.7%great, 18.0%good). Besides, most patients thought the service had positive effect on their mental stress(16.7%great, 43.6%good, 26.9%fair). Conclusion: The results of the retrospective study indicated that clinical pharmacist can effectively reduce and prevent drug-related, life-related and COVID-19-related problems for COVID-19 patients. This work may provide possible work patterns for clinical pharmacist in other hospital and give more professional service for Fangcang hospital patients.

Rainfall derived infiltration and inflow (RDII) are extraneous water in a sanitary sewer system that are originated from rainfall in a surface runoff form. Most RDII enters sanitary sewer systems through illegal connections or mechanical faults, especially in aged sewer systems. In this study, the physical process of three primary RDII sources: roof downspout, sump pump, and leaky lateral, are investigated using physics-based models. These three sources represent three different flow paths: direct connection of impervious catchments, mixed flow through coarse porous media followed by a direct connection, and percolated flow through compacted soil, respectively. Due to the differences in medium and the flow paths, flow responses of these three RDII sources differ in time and magnitude, and they can be distinctly identified from each other. The typical flow response of each RDII source is represented as an Impulse Response Function (IRF) that is a flow response to a pre-specified representative rainfall computed using physics-based models. The total RDII flow hydrograph is presented as a combination of these three IRFs, and the weighting factors of each IRF is calibrated using a genetic algorithm (GA) technique in a test sewer catchment. The results may shed light on identifying the contributions of different RDII sources in a sewershed and help public water managers to understand the local RDII issues better, which in turn facilitates more effective management of a sewer system.

Keywords: moral, justice, community, walfare1. INTRODUCTIONThe life of the community will be regular, good, and organized correctly when there is a rule that is agreed upon in the community. One form of such regulations is about morals. In Indonesian language, moral is defined as moral. Moral teaching is good and bad received by the community in deeds, attitudes, obligations, morals, ethics and decency (Umanailo, 2014b). Norms and values are the elements contained in the moral and is used as a benchmark to establish the good and bad actions or deeds as a man. The norm can be interpreted as a guideline, the size, the rules or habits that used to set something else or a size. With this norm one can assess the goodness or badness of an act. In addition to the norms, values included in the elements of moral. Value is a price, the contents or meaning of the acts that have a purpose (Warsilah, 2013). The value is in the moral that someone can do well with goals that have value. Morals, norms, and values can run if there are attributes, i.e. properties or actions to do things that produce behavior-behavior that is right in life (Hastuti, 1995).If the actions and interactions among the citizens of the community in harmony or compatible with the values and social norms, then there is a social order. However, if action and social interaction among the residents of the community is not appropriate or is not in harmony with the values and social norms then what happens is the irregularity of social shape can be a variety of the process of dissociative, for example conflict, disorganization, social, social disintegration and a variety of problema social. Based on the foregoing it can be asserted that values and social norms play a role as a referrer and size to behave and act in social life. As stated by Woods, that the social value is the instructions-general instructions that has lasted a long time which directs the behavior and satisfaction in daily life. While the norm is a measure used by the public whether the act committed by a person or group of people is the act of a reasonable and acceptable because in accordance with the expectations of most of the citizens of the community or an act that is deviant because it does not fit with the expectations of most citizens (Umanailo, 2014c). Norm built on social values, and social norms are created to maintain and sustain social value. Violation of the norm will get sanctions from the community. Because of the sanctions, so the members of the community feel a deterrent, or at least reluctant to commit the offense. If it so then in a society will be formed social order.Kohlberg proposed the concept of morality is seen from the reasoning or the reasoning behind the decision good/bad, right/wrong. Reasoning or consideration with regard to the breadth of insight about the relation between the self and others, rights and obligations. The relation of self and others in the underlying principle of equality , meaning that other people the same rank with themselves. Thus between the self and the other self can be interchanged. This is called the principle of reciprocity (Umanailo, 2014a). Morality is essentially a settlement of the conflict between the self and the self of the other, between the rights and obligations in the convention. If good and bad are embraced in the convention in accordance with the moral principles of the individual, then the individual following the convention. However, if the good-bad espoused in the convention not in accordance with the principles of the moral individual, then an individual is not carried away by the current following the convention, but rather stick to the principle of his own moral, so that is considered good is not confined by the system, so it can be looked at conventions from outside the social system itself, to uphold the principle referred to (Izzati, 2016). The difference between norms, rules or expectations of society with the moral principles of the individual will occur, when there is a condition such as that described Ronggowarsito as the era of the wild (age crazy). In the era of mad said Ronggowarsito that if we don't do a crazy we will not get the part. But still more good people who remember and alert, which is certainly not in accordance with the moral principles espoused in those days. 2. LITERATURE REVIEWJustice is essentially treats someone or the other party in accordance with their rights. Are the rights of each person is recognized and treated accordingly with dignity and dignity, equal in rank, and the same rights and obligations, without distinction of race, descent, and religion. Plato divides justice into justice and individual justice of the state. According to him, the justice of the individual is the ability of a person mastering yourself with how to use ratio (Hamiru & Umanailo, 2019). While according to Aristotle, justice is divided in five forms, namely 1) justice commutative, i.e. the treatment of a person without viewing the services he did, 2) distributive justice, namely the treatment of a person in accordance with the services that have been made, 3) the justice of the nature of nature, i.e. give something in accordance with that given to other people to us, 4) justice is conventional, that is someone who has obeyed all the laws and regulations that have been required, 5) justice according to the theory of the repair is someone who has been trying to restore the good name of another person who has been polluted. Justice is an abstract thing, so it will be difficult to realize a justice if you do not know what is the meaning of justice (Zuhroh et al., 2020). Diverse, it can be shown from the different opinions expressed justice in two groups, namely common justice or justice according to the will of the legislation that must be enacted for the sake of public interest and justicespecial based on the similarity or proportionality. In general, justice and the word fair is used in four things: balance, equality and non-discrimination, the granting of rights to those entitled, and the delegation of a form based on level and eligibility. Fair is a state of being balanced. If we look at a system or a set that has a variety of parts are made for specific purposes, then there should be a number of terms, either the right size on each section and the pattern of linkages between those parts. By gathering together all terms that, this set can survive, giving the effect that was expected of him, and fulfill the task that had been laid for him. Any balanced society requires various kinds of activity. Among these are economic activity, politics, education, law, and culture (Hamiru et al., 2019). All that activity should be distributed among the members of the society and each member must be utilized for an activity proportionally. Against discrimination in any form. When it is said that a person is doing is fair, what is meant is that the people that looked at all individuals are the same, equal, without discrimination and preference. In this sense, justice is the same with the equation. With justice is a necessity not the preservation of the diverse feasibility of the different and looked at everything and all people are equal, justice is synonymous with oppression itself. If the act of giving is equally seen as fair, then it is not giving to all equally average also must be seen as fair. The general assumption that anything that can be donefor the same average to all people is justice comes from the mindset of this kind. But if what is meant by justice is the maintenance of equality at the time of the feasibility indeed the same, that sense can be accepted. Therefore, justice requires and implies the equation like that. The notion of justice what is meant is the maintenance of individual rights and the granting of rights to each object of that deserve it. In this sense, despotism is the disappearance and violation of the rights of the other party (Umanailo et al., 2018). Understanding justice, namely social justice, is the justice that must be respected in the laws of man and each individual really have to fight to enforce it. Justice in this sense rests on two things, the rights and priorities, namely the existence of different rights and priorities as individuals when compared with others. If someone is working on something that requires the results of, for example, it has priority over the fruit of his work. The cause of the onset of priorities and preferences it is the work and of its own activity. Similarly with the baby, when born by his mother, he has a claim priority over its mother's milk. The source priority that is the plan of creation in the form of system of release of mother's milk for the baby. Second, the distinctive character of man, created in the form in which humans use a number of ideas or methods, so with mediation of ideas and methods, he can achieve its objectives. Ideas that will shape a series of ideas that its determination can be with the intermediary (Tahir & Umanailo, 2019). In summary, so that each individual community can achieve happiness is well-maintained. Understanding human justice asit is recognized by the consciousness of all people. While the point diametrically opposite is oppression which is rejected by the consciousness of all people. Understanding justice and injustice is on one side rests on the principle of priority and presedensi, and on the other side rests on the principle of nature man is forced to use a number of conventions to design what it should be, and what should not as well as they ponder both good and bad (Sa’adah et al., 2019). The sense of justice which referred to action is to maintain eligibility in the delegation form, and does not prevent the overflow and grace at the time of the possibility to realize and improve on it has been made available. All, at the level of form that no matter where, have the placement of the characteristic related to the ability to receive the emanations of the. Given the Substance of the Divine is Absolute Perfection and Absolute righteousness that always gave emanation, then He will surely give you a form or perfection of form to any suit that may be received. So, Divine justice according to the formulation this means that each takes form and the perfection of its form in accordance with the feasible and possible for him. Experts wisdom (teosof) slung nature of the fair to the Lord to be in line with (the height) of the Substance of God and form the perfect nature for Him. In the other position, the flow of which is known to the Philosophy of John Rawls Of Theory of Justice. 3.

Starting from it, the moral has covered various aspects of life such as cultural, religious, political, educational and economic. ReferenceHamiru, H., Hehamahua, H., Umanailo, M. C. B., & Hamid, I.

La cattiva gestione di rifiuti, l'uso improprio di metalli pesanti nell'ambito di industrie ecc, provocano alterazioni importanti per cui l'impiego di tecniche di risanamento ambientale risulta essere necessario. Per capire se un sito è contaminato, va effettuato un piano della caratterizzazione. Esso è costituito dapprima da una modello preliminare in cui si effettua una ricostruzione storica del sito in essere, e successivamente si identificano le sorgenti di contaminazione e i bersagli raggiunti attraverso i percorsi di contaminazione.  Si giunge così ad una analisi di rischio, a valle della validazione dei risultati dapprima ottenuti, che ci consentono di redigere i due fondamentali elaborati della fase di caratterizzazione di un sito potenzialmente contaminato ai sensi del Dlgs. 152/06. Nel presente studio sono stati ripercorsi i punti salienti del piano della caratterizzazione in cui si sottolineano i punti di forza e di criticità di tale iter e le linee guida amministrative da seguire. Al fine di percepire le diverse fasi del piano, si è fatto riferimento a diversi casi studio. L'obiettivo è quello di comprendere quali sono gli step fondamentali da effettuare nell'ambito del piano della caratterizzazione di un sito contaminato in Italia.

In this paper, we deal with the numerical approximation of the coupled wave equation of Kirchhoff type with nonlinear boundary damping and memory term. Since the equation is a nonlinear equation, the Raviart-Thomas mixed finite element method is one of the most suitable techniques to obtain the approximated solution. In this paper, we will show that using the Raviart-Thomas method the optimal convergence order of the scheme can be achieved. To that end, we prove the necessary lemmas and the main theorem. Finally, the efficiency of the method is certified by numerical examples.

In this article we consider a microscopic model for the host-vector disease transmission based on configuration space analysis. We model transmission with a birth-death mechanism in the vector component and mobility in the host component. Our intension is to show that a Vlasov type scaling, which is a mean-field-like scaling of an interacting particle system, leads to the known equations used in epidemiology to model host-vector disease spread on the kinetic level. Configuration space analysis is here a very powerful tool. The concepts of harmonic analysis in this framework are used to derive first the dynamics of correlation functions - giving a hierarchical system of equations comparable to the well known BBGKY hierarchy in Hamiltonian dynamics. A proper Vlasov type scaling guaranties that the resulting Vlasov hierarchy is closed and possesses the property of preservation of chaos. The limiting system of time evolution equations is non-linear and strongly related to the well-known Fisher-KPP equations. A numerical analysis strengthens the analytical results. Moreover, the dynamics of case numbers over time gives qualitatively the solution of a SISUV-ODE system. The microscopic dynamics hence leads to the right behavior in the scaling limit.

Assuming non-Fourier thermal effects, Tzou's dual-phase-lag model has been applied to introduce the governing heat conduction equation in the presented mathematical model. Moreover, in order to design a well-posed stable dual-phase-lag model, the governing time fractional dual-phase-lag heat equation has been established by introducing conductive temperature and thermodynamical temperature, satisfying the two-temperature theory. Due to the application of phase-lags the heat conduction equation became hyperbolic. The corresponding governing equations of motion and stresses have been considered in two-dimensional bounded spherical domain. The spherical boundaries are assumed to be traction free. The Laplace and the Legendre integral transforms have been applied to obtain the analytical solutions of conductive and thermodynamical temperatures, displacement components and thermal stresses. The Gaver-Stehfest algorithm has been employed to achieve the time domain inversions of Laplace transforms numerically, satisfying the Kuznetsov convergence criteria. Classical, fractional and generalized thermoelasticity theories has been recovered theoretically and numerically as well for various fractional orders and phase-lags values.
An Analysis  of Youth, Innocence, and Sexual Maturity in Horace’s Odes 1.23 and 2.5

The discussion of innocence and sexual maturity in Horace’s Odes 1.23 and 2.5 is quite complex. This paper aims to understand Horace’s perspective on these topics through the analysis of the figurative portrayals of Lalage and Chloe. By illustrating the maturation of the two girls over the course of numerous poems, Horace shows how this process, while always stepwise, manifests differently depending on the person. His discussion of what exactly makes a person “youthful” suggests that the innocence of a girl is tied to her defining character trait. Ultimately, only the change of seasons brings the arrival of sexual maturity, which is defined by a girl’s attachment to her dominating husband. Both Odes 1.23 and 2.5 utilize repeated Greek pseudonyms to show the character development of these women over the course of the Odes. The Greek names could either be interpreted as pseudonyms for free-born Roman women (which is typical of Augustan authors) or a Greek freedwomen. Both the names are mentioned in multiple Odes, but it is unclear whether these refer to the same or different women in each circumstance. By deconstructing their various depictions, it can be extrapolated that Chloe gains agency and dominance as she ages while Lalage loses her freedom and sense of self.From her appearance in Book 1 to her last appearance in Book 3, Chloe grows from a young, inexperienced lover to a dominant mistress that controls her love affairs. It has been argued by some scholars that Chloe is a consistent character throughout the Odes and that the order in which she appears in the Odes is representative of her character changes.[1] In 1.23, Chloe is a young girl, newly matured, finally ready for a relationship with a man. She is extremely scared of this unknown territory: everything from the lions and tigers (1.23.9-10) to the harmless breeze (1.23.4) and lizards (1.23.6) frighten this inexperienced girl. Chloe appears next in 3.7 as the unsuccessful temptress of Gyges, a married man. She is described to ignibus uri (3.7.11) for Gyges and that she temptat mile...modis (3.7.12). The outwardness of her fiery passion and her knowledge of seduction (she knows a million ways to seduce a man) indicate that Chloe has matured sexually. However, she is still not skilled enough to successfully capture Gyges; the poem implies that Chloe is misera (3.7.10) because of her failure.[2] In Ode 3.9, a conversation between Horace and Lydia, Chloe is described as docta (3.9.10) as she has finally learned the dulcis...modos (3.9.10) necessary to steal a man, in this case, Horace. The fact that she regit (3.9.9) Horace indicates that Chloe is now in control of the love affair and of her actions, rather than being a passive recipient of nature’s whims. The epithet Thressa (3.9.9) indicates that unlike her quiet demeanor in Ode 1.23, Chloe now has a “wild and passionate temperament.”[3] The placement of Thressa before Chloe further emphasizes this fact. Although she is more experienced and exerts more agency, Chloe is still somewhat powerless: she is still executitur (3.7.19) by Horace, the agent of Venus, as he controls the relationship. Finally, in 3.26, Chloe has reached the height of sexual maturity. She is the regina (3.26.11) of her erotic world, now rejecting Horace. Horace mentions Sithonia nive (3.26.10) to suggest that Chloe, who was once gentle like spring, is now reminiscent of the cold, unforgiving winter.[4] The use of arrogantem to describe Chloe solidifies her completed transition: she changes from a pavidem (1.23.2) deer to a misera (3.7.10) temptress to a docta (3.9.10) lover, and finally, to a headstrong regina (3.26.11).[1] McCune 2016, 573.

Abstract:                                          This paper explores the effect of pregnancy on women’s access to power in ancient Greece and Egypt. It argues that the politico-economic institutions dictated the extent of a non-pregnant woman’s power in these societies, and because of this, non-pregnant women in ancient Egypt were afforded more civil freedoms than those in Greece. However, in regards to determining the power of pregnant women, sociocultural influences, such as religion, played a much bigger role. Due to the Western, female-centric view of fertility in Greece, pregnant women were allocated significantly more ideological power than usual, which is evident in their ability to actively participate in their healthcare. On the other hand, the association of men with birth resulted in pregnant Egyptian women losing their preexisting political, economic, and sexual freedoms. Through the cross-cultural comparison of these two nations, it can be determined that the influence of pregnancy depends entirely on cultural infrastructure of a country. The Burden of a Child: Examining the Effect of Pregnancy on Women’s Power in Ancient Egypt and GreeceIn the ancient world, parturition was considered to be a sacred phenomenon. The overlap of medicine, myth, and magic associated with childbirth differentiated pregnant women from other members and granted them a unique status in society. The fascination around pregnancy is perhaps best encapsulated by the use of various rituals to enhance fertility, conception, and parturition. It has been shown that ancient Greek women often referred to calendars to identify the optimal environmental circumstances for conception.[1] In addition, many women and priestesses belonging to the cults of goddesses such as Artemis or Demeter engaged in rituals to enhance fertility.[2] At the sanctuary of Artemis at Brauron, there is evidence that garments were donated to the goddess by women who had given birth or on behalf of those who had died during childbirth.[3] Garments were popular, and amongst the most luxurious, gifts, signifying that the ancients were willing to spend riches on pregnancy related matters. In ancient Egypt, fertility tests were performed by placing a clove of garlic in the vaginal region; since the womb was thought to be connected to the alimentary canal, Egyptians believed that the scent of garlic could be detected on the breath of a fertile woman.[4] In addition, various ceremonies were performed to earn the assistance of the birthing deities including Hathor, Isis, and Neith; in labor, the women was placed in a “house of birth”[5] that connected to the temples of the goddesses. The diverse efforts devoted by the ancient Egyptian and Greek societies to exploring and improving the pregnancy process signifies its importance in their sociocultural structures. This paper examines the types of social power associated women and pregnant women in ancient Egypt and Greece. By comparing and contrasting their social and legal standings as well as the impact of social, cultural, political, and economic forces on these standings, it aims to identify the effect on pregnancy on women’s statuses, and more specifically, power in society. To better clarify the meaning of “power”, sources will be read through the lens of Mann’s well-regarded IEMP model, which is discussed in detail below.[6] While there are numerous similarities between the two societies, the distinguishing factor between non-pregnant women in Egypt and Greece is the access to political and economic power. While women were officially considered citizens in both states, the politico-economic structure of Egypt enabled women to legitimize their citizenship with formal monetary and governmental contributions while that of Greece prevented women from fully participating in public life. However, pregnancy changes the ideological power allocation in these societies. The sociocultural differences, in particular, religious rituals and myths and social practices, between the states resulted in women in Greece gaining some ideological power during pregnancy while women in Egypt were somewhat stripped of their pre-existing autonomy. Mann’s Sources of Social Power: Ideological Power Drove the Ancient WorldMann defines power, in its most general sense, as “the ability to pursue and attain goals through mastery of one’s environment.”[7] Power arises from the human need to chase individual goals, and therefore, create networks of social interactions to obtain these goals. These networks, also referred to as four primary sources of social power in Mann’s IEMP model, have distinct capabilities and boundaries. It is the combination of these sources, in particular the utilization of the intensive and extensive power they possess, that drives human achievement.This particular model was chosen because it has been cited frequently in the literature, for example, as a scheme that “comprehensively [clarifies] the power situation at the macro-level”.[8] In addition, Mann’s focus specifically on the ancients lends well to this paper, as it is well recognized that the sources of power driving major changes in the world alternate through the centuries. With regards to the ancient world, it is postulated that ideological power was the dominating network, as it was a time when religion and its associated “emotional/ritual techniques of solidarity and impressiveness”[9] spread.  Mann’s model provides the framework to compare and contrast the freedoms given to and limitations placed on women in the ancient world. For those unfamiliar with the model, its facets will be explored in depth in this section. The first of these powers is ideological, the power of belief. This belief can be personal or institutionalized, such as with religious authority, and is entirely faith based. Its unprovable nature is best conveyed, “You cannot argue with a song.”[10] Mann proposes that this power stems from the ability to monopolize norms, meaning, aesthetic/ritual practices and from the claim to knowing what is “right” and just. Although the knowledge of ideological power cannot be proven, its message does not have to be false or manipulative; most successful ideological movements contain rational, legitimate messages. While religion is an obvious example of ideological power, secular movements, such as Marxism, can be just as influential. In stark contrast, economic power, simply put, is the access to resources. More specifically, it relies on one’s capacity to control the production, distribution and consumption of goods, thereby effectively inserting oneself into the consumer relationship as a middle man. Marxists often focus on production as being the ultimate source of power because labor precedes the other parts of the chain. Mann also proposes that economic power is frequently dispersed and might not directly correlate with a hierarchical class structure, although it can. According to Mann, though, the most coercive, concentrated form of power is military strength, or the mobilization of violence. While commonly thought of as the utilization of force during wartime, violent forms of social control, such as slavery, are subsections of military power that exist during peacetime. In direct contrast to political power, which will be discussed below, military influence has an extensive reach even outside of state borders. Mann gives the example of a local tribe which still continues to supply an annual tribute to its conquerors despite the fact that the nearest military base might be over 300 kilometers away. Finally, Mann presents political power as the institutionalized regulation of society, or, in other words, state power. Unlike the other sources of power in IEMP, political power is contained within a society and is constrained by its borders. This limitation of power can be observed in the variable influence of a teacher. External to a teacher’s power sphere, ie: school, his political power as an instructor ceases to exist, which is why he cannot assign homework if encountered at a grocery store. Also, in contrast to the rest of the power sources, political power relies on a “center” and falls with only a particular group or subsection of a group. Throughout the remainder of the paper, these identified sources of power will be referenced. In addition, the sources and consequences of sexual power, which was added to this existing model by later historians, will be discussed. The Legal Statuses of Women in Ancient Greece and Egypt Differ From the analysis of the earliest available art, archeological, and textual records, it can be interpreted that the legal status of women in Egypt was equivalent to that of men.[11] Both men and women were able to purchase and sell property, which allowed women the chance to accumulate economic power. The ownership rights of Egyptian women are best communicated by an engraving on the Statue of Nakht-mut, a sculpture from the Third Intermediate Period of Egypt, 1070-664 BC. (Figure 1).[12] Mut was considered to be the mother goddess of Thebes; her double crown is thought to represent her rule over both Upper and Lower Egypt.[13] The statuette reads, “Act excellently for our daughter…Let her seize this property and kill anyone who will trespass against her!”[14] Not only is the woman’s right to ownership so fierce that she can “seize” the property, but it is so great that she may “kill” to defend it. In the legal arena, both sexes could initiate court cases or be sued by others. Women were responsible for their own civic actions and although it was rare, they could serve as witnesses in a court case or for legal documents and sit on juries.[15] The extent of women’s full legal rights was manifested in her ability to initiate divorce and opportunity to remarry thereafter.[16] This legal equality of the sexes most likely stems from political and economic structure of Egypt. Egypt functioned as a theocratic monarchy; the king was viewed as an intermediary to the gods and his laws as manifestations of the gods’ wills.[17] The political power of the state was concentrated in him, and to some extent, the royal family, which prevented any group of civilians, such as upper-class males, from gaining an advantage over others.[18] This allowed for political power to be somewhat evenly distributed among citizens. In addition, because Egypt was not an empire but rather a contained state[19], women were able to contribute to the economy, which also granted them economic power. The economic and political power of women in Egypt is evident in a section of the instructions of Ptahhotep. Ptahhotep was a vizier, essentially a first minister, during the Fifth Dynasty of Egypt, which spanned from the late 25 BC to early 24 BC. Also known as the Maxims of Ptahhotep, this novel belongs to the sebayit “instruction” genre, filled with “perspicacious advice”[20] regarding a variety of topics from table manners to beauty tips for one’s spouse. Ptahhotep’s guidance was “reworked”[21] into a literacy collection that was often read by young men from influential families as a guide for how to live an ordered, harmonious life.[22] One particular passage from his work revolves around advice concerning how to take care of one’s wife; surprisingly, it also alludes to the power women possessed —- men needed to “restrain”[23] women from exercising their power. The author goes so far as to compare a woman’s eye to a “storm,”[24] indicating the supposed wild powers of females. One of the lines specifically warns not to “contend with her in court,”[25] which implies that women held legal power and were willing to fight for their rights. This text suggests that women were feared politically because of the legal autonomy they possessed.In stark contrast, women in Greece were severely restricted legally. Although they were official citizens, it can be argued that their citizenship was merely a formality to legitimize the citizenship of their male offspring.[26] In reality, they were legal minors. Although a man was called a polites, citizen, a woman was never referred to by this name; instead she was dubbed an aste, a woman belonging to the city, or an Attike gune (Attic women/wife).[27] Athenian women were excluded from the so-called “democracy”[28] ---- they were denied the right to attend assembly, serve on the council, or vote. While the Athenians justified the political equality of free men by the fact that they were all direct descendants of the demigod Erichthonios[29], there is no mention of women in the myth, hence reason to deny them political equality.[30] Instead, the race of women, genos gunaikon, was thought to be derived from Pandora, who was a punishment Zeus created for mankind. In the Theogony, Hesiod describes women to be “wicked” and a “nagging burden” for men; he even asserts that women are simply an “evil for mortal men”.[31] In stark contrast to the men who are metaphorically portrayed as the ever-hardworking “busy” bee, woman are depicted as “drones” who “cram their bellies full of what others harvest.”[32] From this passage, it can be assumed that the supposed laziness and plethora of vices women possessed were considered justification to deprive them of the benefits of citizenship. However, the exclusion of women from public life extends far beyond the political sphere. Women were considered to be a part of the oikos, household, signifying that she was excluded from the public sphere.[33] Their exclusion was taken so seriously in fact that the names of wives and daughters were not even directly mentioned in legal speeches.[34] This mentality is clearly visible in Pericles’ Funeral Oration as he speaks about the excellence of women. He states that a wife’s “glory is great…if there is the least possible talk of [her] among men either for praise or blame.”[35] Because of their diminished legal status, women required a kyrios, a male guardian who was either her husband or the closest male relative, to manage all legal transactions on her behalf. The kyrios handled everything from providing a dowry to litigating in courts, which is a sharp contrast to Egyptian women who could initiate court cases themselves.[36] In addition, the kyrios was required to accompany them in public on the limited occasions when they were allowed to venture outside the house.[37] Women also could not own property independently, thereby depriving them of an opportunity to amass wealth and gain an economic advantage.[38]The Similar Social Standings of Ancient Egyptian and Greek WomenAlthough women possessed political power in Egypt, the social status of women was widely different than their designated legal status. Ancient texts show that while men were differentiated by their professions or income, women were usually referred to as “Mistress of the House”[39] because they rarely held jobs outside the domestic sphere. In addition, women were frequently referred to through the names and titles of either their husbands or fathers, showing that with regards to a social name, they were considered to be dependent.[40] Due to this, a large portion of their social identity was tied to the status of their husband. This fact is evident in “The Instructions of Any”, a didactic text from the New Kingdom[41], which states that “A woman is asked about her husband, a man is asked about his rank.”[42] It is also important to note that marriage was a private affair in Egypt; marriage was not considered to be a religious or political contract.[43] Even though women in Egypt were socially restricted, they experienced more sexual freedom in regards to their appearance and interactions with men in comparison to other ancient cultures. The statue of “Nykauinpu and his wife, Hemetradjet”[44] (Figure 2) shows how the women’s sheath dress[45] functioned to emphasize the sexuality of the female body: the tightness of the dress and the broad shoulder straps draw attention to her round belly and full thighs. Additionally, premarital sex was regarded as socially acceptable and sensuality was encouraged for both men and women, as evidenced by this New Kingdom love poem: “Your hand is in my hand, my body trembles with joy, my heart is exalted because we walk together.”[46] In comparison to Egyptian society, the social status of women was further diminished in ancient Greece. Greek society was highly patriarchal: a woman’s primary role was to produce children, in particular, male heirs.[47] Often female and agricultural fertility were commonly associated, as is seen in the socially acceptable metaphor of a husband “ploughing” his wife, suggesting that the purpose of marriage and women at large was to bear children.[48] There was immense pressure on women to birth children because men faced severe penalties if no children were produced in a marriage; for example, if a wife died and the family was childless, her dowry was to be returned to her family.[49] The social restrictions placed on women are apparent in marriage rituals when a woman is ceremoniously transferred from a father’s to a husband’s home, much like property.[50] Although women could in theory initiate divorce, apoleipsis, there are only two instances of this recorded in textual evidence.[51] Hipparete, the wife of Alkibiades, had to appear before an archon, a chief magistrate of a city-state, in a very formal and public procedure; this is a sharp contrast to apopempis, divorce initiated by the husband, in which the wife was simply returned back to her family.[52] Furthermore, Hipparete’s attempt to divorce was unsuccessful because she was forcefully taken by husband, once again emphasizing the utter lack of control women possessed. For the most part, women were confined to the oikos because Greece was a decentralized empire.[53] Women could not contribute financially since the economy was trade based and there was a surplus of men to make up the labor force.[54] This inability to obtain economic power could be perceived as the direct cause of them being treated as second-class citizens. While women had some authority at home, it was greatly augmented if they had sons.Most scholars agree that, although both were socially restricted, women in Egypt were afforded more political, economic, and sexual freedom than those in Greece.[55] As Herodotus[56], an ancient Greek historian, points out in Book II, “…the Egyptians themselves in their manners and customs seem to have reversed the ordinary practices of mankind. For instance, women attend markets and are employed in trade, while men stay at home and do the weaving.”[57] The fact that a man from ancient Greece finds Egyptians to have “reversed ordinary practices” further emphasizes the dichotomy between these two ancient societies. However, the status of pregnant women in both nations is still heavily debated. To understand how pregnancy contorts a woman’s ideological power, the culture of both societies, in particular religious rituals/myths and social practices, must be examined. A Women-centric View of Pregnancy in Ancient GreeceThe presence of female physicians in ancient Greece indicates that women were allocated a certain amount of expertise in medical topics and hence possessed some degree of informational power.[58] While female physicians were far and few, they were a part of the fabric of Greek society. The absence of a list of female physicians from antiquity indicates that they were an everyday part of the ancient world.[59] Practicing medicine was one of the few respectable occupations available to women, although difficult to pursue without connections or money. From the tale of Hagnodike[60], who was dubbed “the first women physician”, it can be extrapolated that Athenian women began practicing medicine as early as the fourth century BC.[61] Initially, women were only permitted to be midwives, but by the end of the fifth century, a distinction between female doctors and midwives appeared. One example of a female doctor is Phanostrate[62], who was called a “midwife and doctor”[63] on her gravestone. Interestingly, the word iatros is used, which is a typical word for “doctor” in Greek, suggesting that there might have been no distinction between male and female doctors. A section in Plato’s Republic captures the prevailing attitudes towards female physicians in antiquity and supports the notion of equality between female and male physicians. Plato argues that in the ideal state, people should be assigned to jobs based on their given aptitude for the profession rather than their physical characteristics.[64] To defend his argument, he points to the existence of female doctors and the fact that women are physicians because they are skilled at medicine. It is important to notice that Plato is not trying to convince people that there should be female physicians —- he is using them as an example to prove his point. As Pomeroy points out, “Plato did not have to prove women’s aptitude for the medical profession. On the contrary, his case rests on the existence of female physicians in the Athens of his own day.”[65] He writes that a “man skilled in medicine and a woman skilled in medicine - in respect to their minds - have the same nature,”[66] suggesting that he does not view intellect to depend on gender. Through the analysis of Plato’s Republic, one can conclude that little distinction was made between male and female physicians, especially in the gynecological/obstetrics realm. It can be interpreted that women in Classical Greece possessed some degree of ideological power since the empire had faith in their medical abilities.The presence and acceptance of female physicians suggests that because women could choose to be physicians, they could also choose to actively participate in their own prenatal health care. The fact that women were generally granted more power with regards to medicine[67] and personal health suggests that pregnant women in Greece, because they were pregnant, might have possessed more ideological power than non-pregnant women. The analysis of the Hippocratic corpus, a body of Greek medical writings from the fifth and fourth centuries which primarily concentrate on obstetrics and gynecology, provides insight into how pregnant women were viewed by medical professionals.[68] Examining the Diseases of Women and the Nature of the Child in particular suggest that pregnancy garnered women more respect and freedom than usual. In The Diseases of Women, Hippocrates portrays carrying and delivering a child as a difficult, intricate task. By emphasizing the hardship undergone by women during menses and childbirth itself, he brings attention to the sacrifices women make. Hippocrates writes that “it requires much attention and knowledge to bring a child to term and provide for its nourishment in the uterus, and then to give birth to it”[69], depicting carrying a child as a skilled task. This indicates the great responsibility endowed upon women and the competency they must possess to bring a child into the world. In another treatise, the Diseases of Young Girls, Hippocrates observes that young girls often suffer from a maddening “sickness” that arises from puberty. His proposed treatment: “if they become pregnant, they become healthy.”[70] Although its demeaning attitude must be acknowledged, it is worth noting that pregnancy was perceived as a cure to the irrational temperament of girls, thereby implying that pregnant women were sensible. These sources support the notion that the Greeks, at the very least, respected pregnant women and showed appreciation for their physical contributions.In The Nature of the Child, Hippocrates contradicts his sentiment on abortions expressed in the Hippocratic Oath. In his Oath, he swears to “not give to a woman a pessary to cause abortion” but that he “will keep pure and holy in both my life and art”.[71] His statement implies that he considered abortion to be an impure, unsacred act that should be avoided. However, in the The Nature of the Child, Hippocrates discusses abortion in a matter of fact tone to explain fetus articulation; he does not make any indication to the unethicalness of the procedure. “Many women have aborted a male fetus little before 30 days, and it showed not articulation, whereas fetuses aborted after…showed articulation.”[72] This contradicts his opinion in the Hippocratic Oath and supports the evidence from early Greek medical treatises that abortion was only avoided by physicians because of the concern for the dangers involved.[73] This text indicates that abortion was an option available to Greek women, and while not encouraged, remained their choice —- one can reason that pregnant women had some control over their own bodies. In comparison to other points of time in a Greek female’s life, such as when she is forced to marry or manage the household, pregnancy afforded her moderately more power over her body and actions. From the attitudes toward female physicians and pregnant women, it can be assumed that the Greeks viewed women to be knowledgeable with regards to childbirth and women’s health as a whole, which allowed pregnant women to indirectly gain a perceived higher educational and social status than non-pregnant women.Ancient Egyptian Society Viewed Men as CreatorsIn contrast to Greece, there is much evidence that suggests pregnant women in Egypt might have been more restricted than their non-pregnant counterparts. Contrary to many scholars’ beliefs, in ancient Egypt, a woman’s power did not stem from her ability to produce children. In fact, the opposite might have been true—- a woman’s association to fertility diminished her autonomy.[74] Unlike most other ancient cultures, Egypt afforded women many legal, political, and sexual freedoms, such as, in rare cases, ruling the country.[75] Nevertheless, Egyptians designated the power of procreation as a purely male characteristic, which contradicts the typical Western belief. This Western belief is evident in phrases such as “Mother Earth”, European women’s dresses that accentuate the belly, and that fact that women were typically labeled as “barren”, rather than men. The Western association of women with fertility derives from Classical antiquity.[76] Although some Greek medical views contradicted this belief, folk myths, such as Zeus swallowing his wife, Metis, to be able to birth his daughter, revolve around female fertility.[77] In addition, it is important to note that fertility of the earth is under the power of the female goddess, Demeter. According to myth, when Persephone, Demeter’s beloved daughter, is snatched to the underworld by Hades, the earth becomes a barren wasteland.[78] The fertility of the earth as well as of women, which were typically tied together, seem to be centered in a woman herself, Demeter.[79] However, the female-centric model of fertility is not accurate for Egypt. The Egyptians' association between birthing and men is evident in their language and myths. The Egyptian verb for conceiving literally means to “receive” or “take”, indicating that the woman receives the formed infant from the man.[80] This notion is also supported by Akhenaton’s Hymn to Aton depicting god to “place the seed” in the women and “make the sperm into a person.”[81] It is also important to acknowledge the role of semen in numerous conception myths. In the tale of Setne Khamwas and the Magic Book, Setne, a priest of the god Ptah, falls in love with a woman, Tabubu.[82] One particular line reads, “She received [the fluid of] conception from him”[83], suggesting that men provided women with the ability to give birth. Another example comes from the Contendings of Horus and Seth, where Isis is described to “put the seed of Horus on the lettuce that Seth ate every day, and Seth arose pregnant….”[84] The ejaculate of Horus is clearly the root of conception; the symbol of “lettuce” is also quite telling considering the fact that the plant’s “milky white sap”[85] was connected to fertility. These cultural facets suggest that while pregnant women had power over many aspects of their lives, this power was due to the fact that they were female citizens, not the fact that they could beget children, which was an ability prescribed to men.In Egyptian religion, the supernatural beings that were responsible for creative fertility were predominately male.[86] One such representation of these divinities was as a bull or ram, which were considered to be masculine animals; such is the case with the ram-headed god Khnum creating children through his potter’s wheel[87] or the labeling of a divine king as “The Strong Bull of the Gods”[88] because of his ability to produce successors. Egyptians believed that “male creativity in fertility”[89] was so powerful that they had the ability to dictate the sex of the child they produced. This could provide an possible explanation as to why female infanticide was more prevalent in ancient Greece in comparison to Egypt, which lacks evidence to support the presence of this practice.[90] According to Zimmern, the practice of exposing female infants existed primarily because “the provision of a dowry weighed heavily on a Greek father’s mind.”[91] However, Patterson debates that females were considered a “valuable social and political asset”, hence negating the impact of the expenditure associated with a dowry and reason for infanticide.[92] Regardless of the frequency and extent to which infanticide was practiced in Greece, the absence of it in Egypt could at least be partly ascribed to the fact that children were thought to be the result of the creative powers of men. The debilitating effects of pregnancy on a woman's ability to exercise her social power can been seen in the instructions of Ptahhotep. The passage suggests that socially, wives were viewed as dependents who needed to be constantly taken care of and pampered. The author insists that to avoid conflict husbands must provide their wives with ample love, food, and clothes. He also refers to a woman as a “fertile field” maintained “for her lord.”[93] This indicates that while a woman’s “usefulness” stems from her ability to bear children, this ability ultimately hinders her autonomy and makes her a subordinate. This implies that pregnant women might have had the least power, compared to other subgroups of women in Egypt, because she was, to some extent, bearing the fruits of labor of “her lord.”[94] As mentioned previously, the youthfulness and sensuality of women is typically captured in ancient Egyptian dress and art.[95] Representations of those perceived as unideal, i.e. those who were not considered beautiful or slender, such as older women who had gone through pregnancy, were rare.[96] Robins comments that “neither pregnancy nor the spreading waistline that many women must have had after years of bearing children is part of the image.”[97] The sagging breasts and loose skin that are present after childbirth and breastfeeding were marker of age and a reminder that a woman no longer embodied culturally accepted beauty standards.[98] It is possible that pregnant women held less social clout than their non-pregnant counterparts because they were “undesirable” to society, thereby depriving them of the benefits of employing their sexual power for social gain. Artwork and other Pregnancy-related Artifacts Show Cultural ValuesFrom inspection, it can be reasoned that pregnant women in Egypt were more socially hindered than the average Egyptian woman or Greek pregnant woman. For Egyptian women, the power that they inherited by being female citizens is somewhat stripped away during pregnancy. However, it is plausible that in replacement of this lost ideological power they gain something else: supernatural powers, which make them almost god-like. The birth-brick recently found in South Abydos is evidence of this (Figure 3).[99] Birthing bricks served both functional and spiritual roles in Ancient Egyptian society. They were one of the many magical items used to protect the mother and the infant during childbirth while also acting as a physical support for a woman in labor.[100] Birthing bricks often had images decorating its faces. On this particular brick, the scene painted depicts a mother, child, and two female attendants (Figure 3). It merges the two stages of the birthing process: the delivery itself (shown through the servants assisting the mother) and the successful birth (suggested by the child playing in the mom’s arms). This birthing brick makes many allusions to the supposed divinity of the mortal mother. Firstly, the mother and child sit on a grand, divine throne rather than the customary four-legged chair.[101] The mother’s hair is painted blue, which is a symbol of godliness in Egyptian art[102]; this particular blue is dubbed as “lapis-lazuli”[103] and is often associated with solar rebirth. The color matches the blue hair of the divine Hathor figures surrounding the mother, suggesting that the mother could represent Hathor, the goddess of fertility and birth.[104] The baby boy the mother is holding is presented with black hair, indicating that he is a mere human. This presentation of the birth suggests that the artist believed the concepts of delivery and motherhood to be of a divine nature. It is especially telling that the mother’s and son’s hair colors differ, suggesting that the mother’s divinity is independent of the child’s status and vice versa. This separation of maternal and child divinity is not present in Greek myth, as can be read in Hera’s objection to returning the body of Hector to the Trojans in the Iliad: “…if indeed you gods grant the same honor to Achilles and to Hector. Hector is but mortal and was suckled at a woman’s breast, but Achilles is the child of a goddess…”.[105] Although both are heroes, Hector’s mother, Hecuba, is a mortal while Achilles’s mother is the goddess Thetis. Hector’s mortal heritage is portrayed to have been tied to the humanness of his mother, and to some extent, be a result of his consuming his mother’s breastmilk.[106] On the birthing brick, the fact that divinity is assigned only to the mother indicates that Egyptians might have believed a pregnant woman to have an intrinsic, almost magical, power.[107]While at face value this newfound power might seem beneficial to women, there is the possibility that ultimately, it isolates pregnant women from the rest of society and pronounces their otherness. This sort of isolation is visible when women are menstruating; an ostracon discovered in Medinet Habu refers to a st hmwt, which is best interpreted as “the women’s place while they were having their menstruation.”[108] The Satire of Trades indicates that washermen were regarded to be low ranking members of society because “he (the washerman) sets himself to do the loincloth of a woman having her period.”[109] The connection between the absence of menstruation and pregnancy[110] suggests that pregnant women also might have received a similar treatment. In addition, the strong association between men and procreation made by the Egyptians renders anyone else involved, such as the women, a subordinate and executor of the man’s will.[111] The divinity of the woman portrayed in the South Abydos birthing brick could stem from the fact that she is the vessel of the godly man, or in other words, divine by proxy. In some sense, her emphasized transition from mortal to divine serves to reinforce what power she has lost because of the transition itself. While she is divine, her identity becomes reduced to child-bearer rather than the “storm”[112] she once was. It is important to note that while there are many statues and reliefs of pregnant women and birthing scenes from ancient Egypt, very little artwork depicting pregnancy has been found dating back to Classical Greece. In the few instances that pregnancy was represented in art, it was mainly in relation to death.[113] This is mostly likely because maternal mortality was prevalent in the ancient world, with rates estimated to be as high as 14%, due to a variety of conditions including hemorrhage, pelvic deformity, eclampsia.[114] An Attic grave relief made of pentelic marble dating back to 330 BCE shows a woman dying in childbirth surrounded by a female mourner, an old nurse, and a servant (Figure 4).[115] The nurse holds the woman’s hand while the servant supports her weight as she leans on what appears to be a couch. The word “daughter” is inscribed above the dying women. It can be assumed that the purpose of this grave relief was to pay homage to this woman in her role as “daughter”, not as an almost mother. While there is evidence of childbirth, the focus of the scene is on the sadness founded on the death of this daughter, not her unborn child. Although pregnancy is somewhat alluded to in this art, it is only because of its association with the dead; it is not honored or celebrated here or in most other Classical Greek art. The lack of pregnancy-related artifacts suggests that Greeks might have viewed feminine health issues to be private and, much like women, as entities to be confined to the oikos.[116] The restriction of women to the domestic sphere is evident in the requirement of a kyrios and the barring of women from economic and political activities.[117] This notion that women belonged exclusively to the home could have affected the Greek approach to women’s health: medical information concerning women was not to be shared outside immediate family and certainly not in a public place.[118] These principles would have prevented artists from portraying parturition scenes, or, at the very least, prevented the distribution of such artworks. Although pregnancy afforded Greek women many freedoms, the limited representation of it in artwork is a reminder of the immense social constraint placed on women. It is probable that ancient Greek society reduced the number of references made to a woman’s ideological power through the forgoing of gynecologically themed artwork. ConclusionsThe mystical nature of pregnancy captured the spiritual, medical, and political interests of the ancients. The inability to conceive had enormous social implications for both men and women, as is evidenced by this line from a letter written in the Twentieth Dynasty of Egypt (1189-1077 BC) found in Deir el-Medina: “You are not a man since you are unable to make your wives pregnant like your fellow men.”[119] As shown in this analysis of textual, archeological, and artistic evidence, the social power of pregnant and non-pregnant women in ancient Egypt and Greece widely differed. With regards to non-pregnant women, political, legal, and economic institutions controlled their access to social power in these societies. A prime example of this is the ability to initiate divorce, which was a right that, unlike Greek women[120], Egyptian women enjoyed[121], hence allowing them to have some say in their relationships and quality of life. It can be inferred that the inability of Greek women to contribute economically and the social view of their worth to be tied to their roles as child-bearers[122] further reinforced the unimportance of non-pregnant individuals in society. However, the importance placed on reproduction lays the groundwork for why pregnancy played such a pivotal role in determining a woman’s access to ideological power in particular.In Greece, due to the association of females with fertility[123], pregnancy increased a woman’s ideological power, thereby allowing women to gain social worth and status to some degree. The source of this power can be attributed to Greek myths such as the Rape of Persephone[124] and birth of Athena[125] that place the power of procreation with women. However, viewing ideological power in Egypt through this Western lens, which is an error often made in the literature, causes one to erroneously ignore the alternate reality: Egyptians viewed conception to be the result of the physical and creative powers of men.[126] The association between males and fertility causes a woman’s political and sexual power to moderately diminish when she becomes pregnant as she 1) is viewed to be undesirable by society[127] and 2) functions as the “fertile field of her lord.”[128] Through the evidence presented above, it can be concluded that pregnancy afforded Greek women independence, or at the very least, some informational authority while it reduced the significance of Egyptian women to birthing vessels. From this analysis, it can be determined that the effect of pregnancy on women’s social power in the ancient world is primarily determined by cultural factors such as religious myths and customs.  Appendix:

How to understand the dynamical collective performances is of particular significance in both theories and applications. In this paper, we are interested in investigating the combined influences of local interaction and processing delay on the asymptotic behaviour in a particle model with local communication weights. As new observations, we show that the desired particle system undergoes both periodic flocking and periodic clustering behaviors when the processing delay crosses a threshold value and the eigenvalue $1$ of average matrix is semi-simple. In this case, the connectedness of the particle system may be absent. Also, the number of clusters is discussed by using the subspace analysis. In results, some criterion of flocking and clustering emergence with exponential convergent rate are established by the standard functional differential equations analysis when the processing delay is small. When the processing delay reaches the threshold value, the system undergoes periodic flocking and periodic clustering emergence. It also shows that the processing time lags qualitatively change the emergent performances in a nonlinear way. Finally, we conclude this study with several numerical simulations that intuitively illustrate the validity of the theoretical results and address some discussions for both variable communication weight and distributed processing delay.
