background: leptospirosis, a spirochetal zoonosis, is considered an occupational disease of persons engaged in agriculture, sewage works, forestry, and butchery. objective: to determine the environmental sources and the knowledge, attitude and practices for leptospirosis among butchers and slaughterhouse workers, as well as the seroprevalence of leptospirosis among cattle and pigs presented for...

Sin,?With reference to the article 'Typhus in the Northern Circars' that appeared in the l.M G. for September 1949 (page 393) I may please be allowed to put forth my views about it. While one agrees that some, if not many, of the pyrexias of unknown origin may be typhus-like or typhus fevers, it is not very safe to diasnose a case of typhus clinically especially when it relates to a couple or s...

The hiccough continued till the 16th day....

It seems so obvious that cheating is wrong that providing a justification is not a main concern: most of the research is empirical and focuses on quantification and correlations. I look at a number of reasons why cheating may be wrong: it provides an unfair advantage over other students, it hinders learning, and it is dishonest. They are unexpectedly weak (often not proving that cheating is wro...

In this paper we solve some problems posed by Kolchin about differential algebraic groups. The main result (from which the others follow) is the embeddability of any differential algebraic group in an algebraic group. A crucial intermediate result, and one of independent interest, is a generalisation of Weil’s theorem on recovering an algebraic group from birational data, to pro-algebraic groups.

It is proved that on any bounded domain in the complex Euclidean space C(n) the Bergman metric is always greater than or equal to the Carathéodory distance. This leads to a number of interesting consequences. Here two such consequences are given. (i) The Bergman metric is complete whenever the Carathéodory distance is complete on a bounded domain. (ii) The Weil-Petersson metric is not uniformly...
