The axial skeleton of all vertebrates is composed individual units known as vertebrae. Each vertebra has anatomical attributes, yet they can be classified in five different groups, namely cervical, thoracic, lumbar, sacral and caudal, according to shared characteristics their association with specific body areas. Variations vertebral number, size, morphological features distribution amongst the...

a series of fe3o4 supported on mesoporous fdu-12 silica systems were prepared by the hydrothermal conditions. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, n2 adsorption–desorption and tem. xrd and adsorption–desorption analysis shows that the mesostructure of fdu silica remains intact after fe3o4 modifications, wh...

Large-scale population declines have been documented across many faunal assemblages. However, there is much variation in population trends for individual species, and few indications of which specific ecological and behavioural characteristics are associated with such trends. We used the British Common Birds Census (1968-1995) to identify specific traits associated with long-term abundance tren...

The purpose of this study is to integrate the findings of the studies related to the relationship between CEO compensation and firm performance in Asian countries. The second concern of the paper is to explore the moderating role of country-specific characteristics on the pay-performance relationship in Asian markets. In order to achieve the study’s objective, meta-analysis technique is utilize...

This paper reexamines the determinants of firm performance and, in particular, the role that firm size plays in profitability. A fixed-effects dynamic panel data model for over 7,000 US publicly-held firms during the period 1987–2006 provides evidence that profit rates are positively correlated with firm size in a non-linear manner, holding an array of firmand industry-specific characteristics ...

Many countries in the developing world are experiencing rapid population aging, prompting concerns that this will have adverse effects on their socioeconomic advancement and on the well-being of older populations. How these forces play out in the coming years is subject to many unknowns, including world and country specific economic conditions, social changes related to family dynamics, urbaniz...
