In this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. Bohemite (Aluminum oxyhydroxide) was prepared as a precursor by strict control of pH and reaction temperature. The gel produced was purified by washing fol...

Gender differences in a psychometrical and in a chronometrical mental rotation test and in a standardized math test were investigated with a sample size of 109 boys and girls aged 7 or 8 years. The results revealed gender differences in all accuracy-based measures, i.e., in the paper-pencil mental rotation test, in the math test, and in the error rate of the chronometrical test. In line with th...

Altogether 164 poor families who had children of normal and subnormal weight and height were studied in Bogota, Colombia. Physical growth was found to be positively associated with expenditure on food, sanitary conditions in the home, mother's age, birth interval between surviving children, level of parental newspaper reading, aspirations for children, and socioeconomic status. Physical growth ...

The purpose of this paper is to explore the main determinants of growth in small and medium sized enterprises (SMEs) in central and eastern Europe. The important role played by SMEs in the economic development of central and eastern European (CEE) countries has attracted the recent attention of academics and policymakers but remains relatively unexplored. Empirical research has suggested that f...

Intra-specific foraging niche partitioning can arise due to gender differences or individual specialisation in behaviour or prey selection. These may in turn be related to sexual size dimorphism or individual variation in body size through allometry. These variables are often inter-related and challenging to separate statistically. We present a case study in which the effects of sex, body mass ...

We provide a new explanation for the narrowing and reversal of the gender education gap. We assume that parents maximize the full income of their children and that males have an additional income, independently of education. This additional income biases preferences towards sons and implies that females have relative advantage in producing income through education. When the returns to human cap...

Using data from eight UK cohorts participating in the Healthy Ageing across the Life Course (HALCyon) research programme, with ages at physical capability assessment ranging from 50 to 90+ years, we harmonised data on objective measures of physical capability (i.e. grip strength, chair rising ability, walking speed, timed get up and go, and standing balance performance) and investigated the cro...
