In mammals, the skin can form complex global and local patterns to meet diverse functional requirements in different parts of the body. To date, the fundamental principles that underlie skin patterning remain poorly understood because of the involvement of multiple interacting processes. Genes involved in the planar cell polarity (PCP) signalling pathway, which is capable of polarizing cells wi...

Humans are born with potential abilities which may emerge due to certain circumstances. In educational environments, needs, interests and capacities of individuals are wide and varied. Therefore, developers and educators of training programs must provide special facilities to identify talented people in the way that justice is observed for all people. Meanwhile, there is no doubt that technolog...

chemical vapor deposition was employed to synthesize carbon nanotubes with ni-loaded mcm-41 and mcm-48 as catalysts and acetylene as precursor at 750°c. mesoporous ni mcm-41 and ni mcm-48 molecular sieves were synthesized by a hydrothermal method and were characterized by xrd and n2 adsorption isotherm. the catalytically synthesized carbon materials were characterized with raman spectroscopy, n...

Non–noble metal catalysts have recently emerged as promising alternatives to the expensive platinum catalysts for the oxygen reduction reaction (ORR). In this study, a new domain of materials, copper based coordination polymers, has been investigated as promising catalysts for ORR. The study was inspired by copper incorporating biomolecules, which efficiently catalyse the oxygen reduction react...

For more than 30 years, underrepresentation of certain racial, cultural, and income groups in gifted and talented programs has been documented as a serious problem. Not only does this issue make gifted programs appear as if they are designed solely for upper class, dominant-culture individuals, but it also means that talented students from diverse backgrounds are not having their needs met. Thi...

introduction. what is the conception of talented students about university and academic and social life? does this conception change before and after entering the university? how these changes occur and in which direction? are these changes important? do the talented students have any solution for academic life problems? method. in a qualitative study 20 medical talented students were selected....

The recruitment and retention of highly talented scientists has become a significant concern for many companies, especially for those whose principal assets consist of talented employees and their knowledge, rather than the tangible assets of cash, buildings or materials. The competition for good professionals has become more intense as companies have become aware that other companies may be wo...

time perspective is a useful psychological construct associated with educational outcomes (Phalet, andriessen, & lens, 2004) and may prove fruitful for research focusing on academically talented adolescents. thus, the relationship of time perspective to age, gender, and academic achievement was examined among 722 academically talented middle and high school students. time perspective was measur...
