When King published 3 articles about demographic entrapment, he recommended that primary health care stop targeting child mortality, indeed that oral rehydration solutions be withheld, in order to reduce population size and evade the demographic trap of a region endangered by the growth of its own population. Using Rwanda as an example, it is possible to calculate the effect of decreasing chil...

conclusions this study shows lower anti-hbs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. also, subsequent measurement of anti-hbs level at the time of entrance to university is recommended for all previously immunized students. results vaccination coverage rates were 74.1%. about half the participants didn’t show serological evide...
Two-dimensional, nonlinear, Hall-magnetohydrodynamical ~MHD! numerical simulations are used to investigate the scaling of the rate of forced magnetic reconnection in the so-called Taylor problem. In this problem, a small amplitude boundary perturbation is suddenly applied to a tearing stable, slab plasma equilibrium. The perturbation is such as to drive magnetic reconnection within the plasma. ...

The life table study of the rice bug, Leptocorisa acuta (Thunb.) on rice (R) and non-rice (NR) system were conducted in the laboratory condition. The average individual fecundity was recorded 100.999 and 59.019 eggs on R and NR system, respectively. The nymphs were observed to pass through six instars with in the duration of 24 and 22 days respectively on R and NR host. The accumulated survival...
AIM To evaluate the efficacy of doubling time (DT) of gastrointestinal submucosal tumors (GIST). METHODS From April 1987 through November 2012, a total of 323 patients were given a final histopathological diagnosis of GISTs on surgical resection or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in Kitasato University East Hospital or Kitasato University Hospital. We studied 53 ...
