Abstract Santa Pudia calcarenite was one of the most commonly used building materials in construction historical buildings city Granada (Spain). As a result, has been mainly studied from petrographical point view previous works. In this work, mechanical properties are studied. The main (compressive strength, elastic modulus and Poisson’s ratio) were determined using corresponding tests. Samples...
Lower Cretaceous (Aptian-Albian) sandstones of the Ghaggar-Hakra Formation in Barmer Basin northwest Rajasthan, India, have a complex depositional history which is confusing given they are quartzose arenites. The heavy mineral grains very well-rounded, and assemblage dominated by zircon rutile suggesting that sediments been recycled multiple times, whilst presence staurolite indicates metapelit...
This paper explores self-perceived mate value (SPMV), and its association with self-esteem, in eight cultures. 1066 participants, from 8 cultural groups in 7 countries, rated themselves on 24 SPMVs and completed a measure of self-esteem. Consistent with evolutionary theory, women were more likely to emphasise their caring and passionate romantic nature. In line with previous cross-cultural rese...
BACKGROUND Few studies have addressed the challenges associated with international students as they adapt to studying medicine in a new host country. Higher level institutions have increasing numbers of international students commencing programmes. This paper explores the experiences of a cohort of students in the early years of medical school in Ireland, where a considerable cohort are from an...

The chapter takes a critical, social-constructionist stance on emotion and critiques psychology’s essentialist stance. Moreover, it introduces a new direction in psychology in which emotion and gender are studied from a discursive perspect...
Abstract The organic-rich upper Lower Jurassic Da'anzhai Member (Ziliujing Formation) of the Sichuan Basin, China is first stratigraphically well-constrained lacustrine succession associated with Toarcian Oceanic Anoxic Event (T-OAE; c. 183 Ma). expansion palaeo-Sichuan mega-lake, probably one most extensive freshwater systems to have existed on planet, marked by large-scale organic productivit...
Located on the northern Vietnam onshore/offshore transition, Hoanh Bo Trough is an excellently exposed terrestrial Palaeogene sedimentary sequence that may be treated as analogue for regional interpretations of and structural evolution Song Hong Basin. The lies to north Basin west Beibuwan Basin, origin which are linked with South China Sea rifting. Field archival well sedimentological observat...
Abstract Neoproterozoic Abu Ghalaga ilmenite-bearing mafic rocks were subjected to geological, petrographical and geochemical studies integrated with mineral chemistry of ilmenite, pyrite magnetite in order deduce their petrogenesis. intrusions hosting the largest ilmenite reserve Egyptian part Arabian-Nubian Shield. Field observations revealed that impound ore, which occurs as interlayer massi...
