Understanding the Factors Affecting the HIV Epidemic in Maharashtra: Application of Proximate Determinants Framework

The Indian HIV epidemic is exhibiting a declining trend, providing an opportunity for meta-analysis and data synthesis by triangulation to delineate the comprehensive picture and to understand the drivers of the epidemic. A proximate determinants (PD) framework is used to tease out factors affecting HIV vulnerability and to segregate the interplay of multiple factors operating within the framework. This study focuses on low-risk general males and high-risk male clients who form bridges between high-risk and low-risk populations. Data from NFHS-III, IBBA-1 and BSS have been used. The findings underscore multi-partner, condom use and partner-mixing as PD for general men, with coital frequency an additional determinant for clients. Partner type and number of lifetime partners are significant determinants for both groups. Significant underlying determinants, after adjustment for PDs, are younger age, marital status and alcohol for general men, and marital status, education, age at first intercourse and prior HIV testing for clients.     

Large apparent compressive strain of metallic glasses

Very high plastic strains exceeding 20% in uniaxial compression tests, which show an inflection in the stress–strain curves of Zr-based bulk metallic glasses, are shown to be a spurious effect due to mechanical interlocking of cracks with shear bands. This type of stress–strain behaviour is misinterpreted as an actual deformation in the literature. The effect of mechanical interlocking is explained by fractographic analysis.

Attainment of an exceptionally high strength in low-carbon steel along with modest ductility through a novel heat treatment route

ABSTRACT

Over the last few decades, the use of steel (the most significant structural engineering material) is facing a significant challenge due to its replacement by other materials (such as composites) possessing higher strength-to-weight ratio/specific strength. This necessitates further enhancement in the strength of steel. In particular, low-carbon steel, in the annealed condition, suffers from inherent problems of poor strength and discontinuous yielding. In this research work a novel heat treatment route of incomplete austenitisation-based cyclic ice-brine quenching has been adopted on low-carbon steel (AISI 1010 steel containing 0.1 wt.% C) without considering any costly alloying or thermo-mechanical treatment. Accordingly, exceptionally high strength (UTS?=?1.7?GPa) and specific strength (226?MPa?g^?1cm³) are achieved after three cycles along with a modest ductility (% Elongation?=?9). This is the highest strength reported so far for low-carbon steel containing 0.1 wt.% C. Yield point phenomenon is also eliminated. This is attributed to a novel microstructure consisting of highly sub-structured fine plate martensite crystals containing internal twin and dislocation tangles along with dispersion of nano-sized cementite particles and clusters of cementite particles.     

Articles of Faith: Freedom of Expression and Religious Freedom in Contemporary Multiculture

ABSTRACT

This article examines the relationship between freedom of religion and freedom of speech and expression within contemporary multicultural liberal democracies. These two fundamental human rights have increasingly been seen, in public and political discourse, in terms of tension if not outright opposition, a view reinforced by the Charlie Hebdo killings in January 2015. And yet in every human rights charter they are proximate to one another. This essay argues that this adjacency is not coincidental, that it has a history and that, in illuminating this history, it is possible to explore how the contemporary framing of these two rights as being in opposition has come about. Looking back to the framing of the First Amendment of the US Constitution, the essay offers an historical perspective that, in turn, facilitates a reappraisal and re-evaluation of these two liberties that is the necessary, albeit insufficient, predicate to the task of addressing the problematic of multicultural ‘crisis' in the contemporary liberal democracies of Western Europe, North America and Australasia, in which the presence of certain religious communities (Muslims, in particular) and the role of religion in public and political life more generally (and, conversely, of secularism) has assumed a central importance.
