Postnatal Factors

Background: The postpartum period is a time of tremendous emotional and physical change for most women as they adapt to new roles and alteration in their physiology. Postpartum depression has seen its rise lately. Multiple factors might be responsible for causation. Symptoms include depression, tearfulness, emotional liability, guilt, anorexia, sleep disorders, feeling inadequate, detachment from the baby, poor concentration, forgetfulness, fatigue, and irritability.Methods: We have conducted a study in 225 postpartum females and assessed them for depression and associated postnatal depression. The 10-question Edinburgh Postnatal Depression Scale (EPDS) was used for assessing depression.Results: Depression was evaluated as 6%. It was also found that 2% mothers with IUD babies developed postnatal depression. 1.33% cases with babies having congenital anomaly developed postnatal depression. 1.33% cases with babies having nursery admission developed postnatal depression.  This has been correlated with many other studies.Conclusions: It is found that perinatal factors do affect postnatal depression as it is found in mothers who have an adverse perinatal outcome. Further research is implicated in this field.

Physical Changes

This article reports on the types of views and misconceptions uncovered after assessing 155 freshman general chemistry students on the concept of particle position during the reversible physical change of melting, using the Melting Cycle Instrument, which illustrates particulate-level representations of a melting–freezing cycle. Animations involving particulate-level representations of phase changes including melting and freezing were viewed and discussed, and the students were assessed a second time, on the concept of particle position during the reversible physical change of dissolving, using the Dissolving Cycle Instrument, which illustrates particulate-level representations of a dissolving-solvent evaporation cycle. Overall, the results of the assessments showed that some misconceptions did remain after viewing and discussing the animations, and that the use of the animations had no effect on the students' views on the movement of particles within the liquid.

Overall Effectiveness

The suitability of the humidity chambers known as Evaporative Cooling System (ECS) developed by Nigerian Stored Products Research Institute as storage structures for mangoes were compared for nine days between June-July 2012. Ambient and ECS Temperature throughout the storage period ranges between 27?C- 31?C and 20?C-27?C respectively, while the corresponding relative humidity was 51%-58% and 70%-81% respectively. Colour change and Weight loss were observed as a physical change to determine effect of each selected ECS on the stored mangoes. There is significant range of ripening in tin-in-pot which led to early deterioration of the stored mangoes. Pot in-pot affects the freshness of the stored mangoes. The overall effectiveness of the tested ECS shows that tin-in-pot is better for the storage of mangoes since for five days, it retains the freshness of the stored mangoes but cannot be used for long due to its natural reaction with the stored fruits.

Abstract The present work brings information on threats to the subterranean fishes in Brazil. Currently, at least 36 species are known, 22 of which are already formally described. Endemism is the rule for most of them. Regarding their conservation, these fishes are in general considered threatened: and most of the already formally described species are included in national lists of threatened fauna, and only four of them are included in the global list of the IUCN. Regarding habitats, Brazilian subterranean fishes occur in alluvial sediments (part of the hyporheic zone), shallow base-level streams, flooded caves, lakes in the water table, upper vadose tributaries, and epikarst aquifers. We detected 11 main threats, mainly related to agriculture, pasture, and hydroelectric plans, but unmanaged tourism and pollution are also significant threats. Two threats affect a high number of species (physical change of the habitat and food restriction). The river basins with the higher number of identified threats are the upper Tocantins (eight) followed by the upper Paraguaçu (six). Effective proposals to protect this neglected component of the Brazilian biodiversity are still scarce, such as monitoring projects and their function in the subterranean communities, besides education projects aiming to develop public awareness.

Water Contents

The paper discusses strength-time relation of unfired soil-lime bricks in presence of different water content of soil as one of principal materials for the brick making. Two batches of soil-lime bricks were made with a mixture of lime, soil and water with a mass proportion of 1: 5.7: 1. Water contents of the first and second batch of soil are 30% and 40.581% respectively. Both batches of brick underwent compression and three point bending test. Absorption and physical change of bricks were also evaluated. Experimental investigation reveals that for both batches of bricks, up to 90 days compressive strength decreases a little but modulus of rupture rapidly decreases with time. The study shows that unfired soil-lime bricks with lower soil water content resulted in better strength performances compared to those with higher soil water content.

Extreme Violence

Capital punishment can be understood as simultaneously an exercise of actual power – the ending of a human life – and an exertion of symbolic, or ritual, power.1 In this combination of symbolic transformation with real physical change, executions are unusual rituals. But the use of extreme violence against the human body certainly does have ritual characteristics, in that it has established rules (which may, of course, be deliberately challenged or broken) and in that these rules are used to make the drastic transformation in the status of the executed party seem legitimate and proper, to reassert more general ideas about the correct social order and to communicate threats and warnings to others who might seek to upset it. The victim of the execution is quite literally marked out as beyond reintegration into society. Their body becomes a kind of text, which can be read in a multitude of ways: the authorities carrying out the killing usually have one set of messages in mind, but the victim themselves, and those who witness or remember the act, may have very different ideas.

On Plato’s Conception of Change

The Difference

In this paper I argue that in several passages Plato sympathizes with the following view: sensible particulars undergo continuous, pervasive physical change; as a consequence, where there seems to be one and the same object which is identical through time, there is in fact a succession of impermanent objects numerically distinct from each other but similar to each other. I illustrate the difference between this view—which invites interesting comparisons with modern and contemporary theories—and other, superficially similar views which Plato criticizes. I also suggest that this view might contribute to explaining Plato’s contention that sensible particulars lack being and are confined to coming to be. Finally, I show that my interpretation was well attested in antiquity; and I put forward the hypothesis that part of the aim of certain Aristotelian claims about substance might be to correct Plato in this respect.

This chapter considers the physical change of the workspace chronologically, geographically, and by industry. From the case studies of pottery, glass, and textile making, as well as food processing, it discusses the standardization of the Roman practice, as seen at Timgad in North Africa, of zoning and conglomerating crafts in early Islam across the Near East and Central Asia. While acknowledging this continuity with the past, it examines the novelty and significance of manufacturing after 800, when ‘post-Roman’ ceased to be a meaningful description of Near Eastern economy, and questions whether urban crafts experienced differentiated or similar forms of development.
