The present work focuses on evaluating the physical and mechanical characteristics of geopolymer concrete (GPC) by replacing the sodium silicate waste (SSW) in place of traditional river sand. The aim is to create eco-friendly concrete that mitigates the depletion of conventional river sand and conserves natural resources. Additionally, the study seeks to explore how the moisture content of filler materials affects the performance of GPC.

SSW obtained from the sodium silicate industry was used as filler material in the production of GPC, which was cured at ambient temperature. Instead of the typical conventional river sand, SSW was substituted at 25 and 50% of its weight. Three distinct moisture conditions were applied to both river sand and SSW. These conditions were classified as oven dry (OD), air dry (AD) and saturated surface dry (SSD).

As the proportion of SSW increased, there was a decrease in the slump of the GPC. The setting time was significantly affected by the higher percentage of SSW. The presence of angular-shaped SSW particles notably improved the compressive strength of GPC when replacing a portion of the river sand with SSW. When exposed to elevated temperatures, the performance of the GPC with SSW exhibited similar behavior to that of the mix containing conventional river sand, but it demonstrated a lower residual strength following exposure to elevated temperatures.

Exploring the possible utilization of SSW as a substitute for river sand in GPC, and its effects on the performance of the proposed mix. Analyzing, how varying moisture conditions affect the performance of GPC containing SSW. Evaluating the response of the GPC with SSW exposed to elevated temperatures in contrast to conventional river sand.

Every few years we have analysed trends in prosecutions under the Food and Drugs Act, 1955 and the various regulations, chiefly for the purpose of ascertaining the principal causes for which proceedings are instituted and to detect changes, if any, from one survey to the next. The period covered in each survey has been three months, but not the same months of the year, and the material, the reports of proceedings received at the offices of the Journal from all parts of the country. In the present survey the method of classification has been the same as formerly, viz., to record prosecutions under similar headings to those under which cases are reported in the Journal with those where foreign material in the food constituted the offence separately identified. As it has appeared obvious for some time now that prosecutions for mouldy food were increasing, these too have been separately recorded.

WHY is it, may we enquire, that so few work study technicians write about work study?

The Equal Pay Act 1970 (which came into operation on 29 December 1975) provides for an “equality clause” to be written into all contracts of employment. S.1(2) (a) of the 1970 Act (which has been amended by the Sex Discrimination Act 1975) provides:

Elsewhere in this issue we review the First (Interim) Report of the Joint Survey of Pesticide Residues in Foodstuffs, published by the Association of Public Analysts (Editor: Mr. D. G. Forbes, B.Sc., F.R.I.C.). The Scheme, planned with meticulous care and executed with the best spirit of co‐operation, sets a pattern for this type of investigation; there are other problems which could be studied in the same manner. Such a response from the bodies representing the major local authorities of the country and their food and drugs administrations—inspectors, food sampling officers, public analysts—is evidence of the concern felt over this particular form of contamination of food. It constitutes a public health problem of world‐wide dimensions. The annual reports of public analysts show that many are examining foods outside the Survey lists now that gas/liquid chromatography, spectroscopy and other highly refined methods of analysis are available to them.

In recent decades, oxytocin (OT) has been extensively studied across disciplines. Yet, the role of OT has been discussed little in the context of politics. This chapter proposes that studying the role of this hormone can enrich and advance the study of politics. The chapter reviews the previous findings on OT categorized into two sections: one that focuses on the biological mechanisms and therapeutic potentials and another that focuses on the effects on social behaviors. This review is not exhaustive but is intended to bring political scientists up to date with the progress in OT studies. Next, this chapter highlights that studying the role of OT in political context will benefit both the OT and political science literature, since there is currently a great interest in the context-dependent nature of OT. I highlight several research questions that can be answered at this intersection. Rather than waiting for other disciplines to complete unfolding the precise role of OT, students of biopolitics can make important contributions. Political science can further understand the biological underpinnings of concern for others and partisan behaviors, while OT applied to real-world settings would demonstrate how different contexts shape its effects.

Although typologies of violence have become more common, relatively little attention has been given to Donald Black’s (1983) distinction between moralistic and predatory violence. Moralistic violence is rooted in conflict; predatory violence is rooted in exploitation. We elaborate Black’s typology and show how it is similar to, but distinct from, other typologies of violence. We also address the criteria by which typologies of any kind might be judged. Borrowing from the literatures on typologies and on standards of scientific theory, we argue that explanatory typologies should be evaluated according to four criteria: the degree to which they are powerful, theoretical, general, and parsimonious. Applying the criteria to Black’s typology, we argue that the distinction between moralistic and predatory violence is an important contribution to the arsenal of the student of violence.
