OBJECTIVES Prior evidence suggests geographic disparities in the effect of maternal education on child nutritional status between countries, between regions and between urban and rural areas. We postulated its effect would also vary by micro-geographic locations (indicated by mountain areas, plain areas and the edge areas) in a Chinese minority area. METHODS A cross-sectional study was conduc...

The Appalachian region has experienced persistently higher poverty and lower earnings than the rest of the United States. We examine whether lower skill differentials or differences in the returns to those skills lie at the root of the persistent Appalachian wage gap. Using Census data, we decompose the Appalachian wage gap using both mean and full distribution methods. Our findings suggest tha...

BACKGROUND We established a rat model of chronic mountain sickness using acetyl-L-cysteine. Then we studied the effects and mechanisms of acetyl-L-cysteine (Da) in rats with chronic mountain sickness using nuclear magnetic resonance (H1-NMR) metabolomics methods. MATERIAL AND METHODS Using NMR spectroscopy combined with pattern recognition and orthogonal partial least squares discriminant ana...

In India, Kerala state is known to have relatively high lightning incidence. The nature of spatial and temporal distribution of past incidents, type of thunderclouds which cause lightning, the topography, proximity to a mountain range and sea point to the possibility of the mountain weather aiding in Cb formation. For investigating the role of mountain weather in convective Cb formation a field...

In this paper, we study a kind of anisotropic p-Laplacian equations in R n. Nontrivial solutions are obtained using mountain pass theorem given by Ambrosetti-Rabinowitz [1].

The classic Coupon-Collector Problem (CCP) is generalized. Only basic probability theory is used. Centerpiece rather is an algorithm that efficiently counts all k-element transversals of a set system.
