Creases provide important clues for the study of bimanual and bisexual variation. The purpose of the present investigations is to attempt the specificity of transverse palmar flexion creases among Lodhis, of Sagar district (MP), India. The basis of the study was 103 males and 102 females unrelated individuals of Lodhis’. For taking palm prints Cummins and Midlow (1859) method were fully adopted...

The recent droughts in Iran made a decline in groundwater table and the migration of villagers to cities was hindered supplying drinking water for the current population. Therefore it should be considered as an important issue. In this regard, it is possible to achieve this goal by constructing underground dams that recently have been suggested to replace by medium and small overland dams. The ...

The "NPD ratio," widely used by yeast geneticists, is of limited applicability and is prone to falsely indicate significant crossover interference in a chi-square test. A simple, better chi-square test for interference in two-factor crosses is described.

Empirical tests are used to help determine whether a given sequence of numbers has statistical properties similar to those of a sequence whose elements are drawn from a uniform probability distribution. The runs test and the maximum of t test are two traditional tests that have been applied to sequences of real numbers between 0 and 1. Motivated by the desire for a set of empirical tests that a...

This paper describes how the use of bicycle helmets in Sweden has changed for different categories of cyclists from 1988 to 2002, and it also estimates future trends in voluntary wearing of bicycle helmets up to the year 2010. Observational studies of the use of bicycle helmets were conducted once a year from 1988 to 2002 at 157 sites in 21 cities. The subjects observed were children cycling to...

The multinomial Dirichlet distribution was used to study the effect of correlation between observations in a sample on the frequency of rejection of the Hardy--Weinberg Law when in fact it was true in the population being sampled. It was shown that the usual X2 goodness-of-fit test of Hardy--Weinberg is very sensitive to non-multinomial sampling. In view of the lack of statistical power of the ...
