An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their est...

Dysfunction in the prefrontal cortex, amygdala, and hippocampus is believed to underlie the development of much psychopathology. However, to date only limited longitudinal data relate early behavior with neural structure later in life. Our objective was to examine the relationship of early life externalizing behavior with adolescent brain structure. We report here the first longitudinal study l...

introduction : adverse health effects of exposure to environmental tobacco smoke (ets) among non-smokers have been studied occasionally in developing countries. the aim of this study was to determine the effects of exposure to ets on outcome in pregnancy methods: in this descriptive and analytical study 600 non-smoking women delivering a singleton live baby were studied in delivery room in haja...

background: primary ovarian pregnancy is one of the rarest forms of ectopic pregnancy having incidence of 1/7000-1/40,000 in live births and 0.5-3% of all ectopic gestations. intrauterine contraceptive device (iucd), salpingitis, infertility, and assisted reproductive techniques are the important risk factors. approximately, 75% terminate in first trimester and are often misdiagnosed as corpus ...

This paper provides a system overview of a new Mars rover prototype Rocky We describe all system aspects me chanical and electrical design computer and software in frastructure algorithms for navigation and manipulation science data acquisition and outdoor rover testing In each area the improved or added functionality is explained in a context of its path to ight and need within the constraints...

background: understanding of the incident electron energy and angular distributions from clinical electron accelerators (linacs) is important for dosimetry and treatment planning. the most important goals of this study were to evaluate the energy fluence and angular distributions of electron beams from a neptun 10pc linac using the monte carlo (mc) code. materials and methods: the linac electro...
