Thermoluminescence Evidence For The Deposition Of Coastal Sediments By Tsunami Wave Action, D. M. Price, Edward A. Bryant, R. W. Young
Thermoluminescence Evidence For The Deposition Of Coastal Sediments By Tsunami Wave Action, D. M. Price, Edward A. Bryant, R. W. Young

Changes in our coastline take on various forms and are the product of differing wave and aeolian processes. Of all these processes tsunami action surely represents the most rapid and violent agent wreaking devastation not only along the immediate shoreline but also extending many kilometres inland. Until now the main line of evidence supporting the deposition of sediments by this means has lain in the careful examination of the sedimentological record. This process is painstaking, costly and time consuming and then not necessarily conclusive. Thermoluminescence may offer an alternative line of evidence which may be taken as either confirmatory or, …
Community Perceptions Of Reasons For Preference For Consanguineous Marriages In Pakistan, R. Hussain
Community Perceptions Of Reasons For Preference For Consanguineous Marriages In Pakistan, R. Hussain
Faculty of Health and Behavioural Sciences - Papers (Archive)
Although the recent Pakistan Demographic and Health Survey (DHS) show that two-thirds of marriages in Pakistan are consanguineous, the sociocultural determinants of such marriages remain largely unexplored. This paper examines the relative importance of the three commonly perceived reasons for such marriages: religious, economic and cultural. The analysis is based on qualitative data collected in 1995 from multi-ethnic and multireligious communities in Karachi, the largest city of Pakistan. Results show that consanguineous marriages are preferred across all ethnic and religious groups to a varying degree, and that parents continue to be the prime decision-makers for marriages of both sons and …
Consanguineous Marriage And Differentials In Age At Marriage, Contraceptive Use And Fertility In Pakistan, R. Hussain, A. H. Bittles
Consanguineous Marriage And Differentials In Age At Marriage, Contraceptive Use And Fertility In Pakistan, R. Hussain, A. H. Bittles

Fertility rates in Pakistan have remained consistently high over the past three decades. While numerous studies have examined sociodemographic determinants, the role of biological factors, and particularly consanguinity, has received little attention, even though marriage between close biological relatives continues to be the norm in Pakistan. Reproductive behaviour among women in consanguineous (first cousin) and non-consanguineous unions was compared, using data from a 1995 study of multi-ethnic communities in Karachi and the 1990–91 Pakistan Demographic & Health Survey (PDHS). The results show that, although female age at first marriage has been gradually rising in both study samples, women in consanguineous …

This paper is a review of the literature concerning the preparation of [60]fullerene amino acid and peptide derivatives. The structure and applications of these derivatives to the biological and material sciences is also presented.
Synthesis Of Thiazole Analogues Of The Immunosuppressive Agent (1r,2s,3r)-2-Acetyl-4(5)-(1,2,3,4-Tetrahydroxybutyl)Imidazole, George R. Jeoffreys, Alison T. Ung, Stephen G. Pyne, Brian W. Skelton, Allan H. White

The synthesis of four of the diastereoisomers of 2-acetyl-5-(1,2,3,4-tetrahydroxybutyl)thiazole and two of the diastereoisomers of 2-acetyl-5-(1,2,3,4,5-pentahydroxypentyl)thiazole and 2-acetyl-4-(1,2,3,4,5-pentahydroxypentyl)thiazole are reported. These syntheses involve the condensation of 5- or 4-metallated 2-(1,1-dimethoxyethyl)thiazoles with 2,3-O-isopropylidene-D-erythrono-1,4-lactone or 5-O-(tert-butyldimethylsilyl)-2,3-O-isopropylidene-D-ribonolactone followed by reductive ring-opening of the resulting lactols. The stereochemistries and structures of some key compounds have been determined by single crystal X-ray structural analysis.
