BACKGROUND It is widely acknowledged that there is a global divide on health care and health research known as the 10/90 divide. METHODS A retrospective survey of articles published in the BMJ, Lancet, NEJM, Annals of Internal Medicine & JAMA in a calendar year to examine the contribution of the developing world to medical literature. We categorized countries into four regions: UK, USA, Other...

in order to study the effects of intra and inter-row spaces and planting pattern on the yield components, seed and oil yield of pumpkin (cucurbita pepo l.), a field experiment was conducted as split-split plot based on randomized block design with three replications during 2009-2010 at the agricultural research station of ferdowsi university of mashhad, iran. two levels of inter-row space (1 an...

susceptibility to diabetes may have begun in the womb, while others may develop diabetes as a result of another disease or condition. Prevention and treatment strategies need to take into account the diverse needs of people with or at risk for diabetes. (Photo credits: Top row, left im age: ©iStockphoto.com/Yuri_Arcurs.

A matrix R is said to be g-row substochastic if Re ≤ e. For X, Y ∈ Mn,m, it is said that X is sglt-majorized by Y , X ≺sglt Y , if there exists an n-by-n lower triangular g-row substochastic matrix R such that X = RY . This paper characterizes all (strong) linear preservers and strong linear preservers of ≺sglt on Rn and Mn,m, respectively.

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

Our goal is to find a mixed strategy (probability distribution on possible plays) for Row which maximizes their expected winnings no matter what strategy Col chooses to execute. Let z denote the winnings of Row player using strategy (x1, x2). Then the solution to the following linear program describes the optimal strategy for Row, since based on any strategy Row chooses, Col may choose a pure s...

In the Surveillance Summary "Health-Related Behaviors by Urban-Rural County Classification - United States, 2013," errors occurred in Table 1 and Table 2. On page 5, in Table 1, under the Micropolitan column, the 95% CI values should have been (75.7-77.3) for the current nonsmoking row and (29.8-31.4) for the maintaining normal body weight row; under the Noncore column, the 95% CI values should...
