This paper analyses the demographic dynamics of the Suyá, a Jê people, inhabitants of the Xingu Indigenous Park, Mato Grosso State, Brazil, during the years 1970-2004. Data was gathered from medical records of the São Paulo Federal University Health Program at the Xingu Indigenous Park. The demographic characteristics addressed include composition by age and sex, crude birth rates, general mort...

objective about 1 % of infants are of very low birth weight. however, they comprise about 50% of infant mortality. we compare the effects of continuous versus intermittent feeding on physical growth, gastrointestinal tolerance and macronutrient retention in low birth weight infants (methods a prospective randomized trial clinical trial was performed from 2004-2005. very low birth weight neonate...

The link between location features and the propensity to start a new firm is a subject that did not get much attention in Iran until recently. This paper is the first attempt on this proposition and is concerned with deliberating the effect of demographical and industrial characteristics of location on start-up rates in Iranian manufacturing industries. To fulfill this aim, regional panel data ...

Amino acids originating from the diet are the principal metabolic fuels for the small intestine, and although the developing intestine is exposed to dramatic changes in the types and amounts of protein, there is little known about rates of amino acid absorption across the apical membrane during development. Therefore, rates of absorption were measured for five amino acids that are substrates fo...

Sub-optimal heifer growth is associated with higher disease rates and reduced future performance and longevity in the dairy herd. This report describes a system for measuring heifer growth from birth to first calving that was used on commercial dairy farms in South West England, in order to gather benchmarking data to feed back to farmers. Weights (n = 8443) were collected from 20 farms. There ...

Many population genetic models have been developed for the purpose of inferring population size and growth rates from random samples of genetic data. We examine two popular approaches to this problem, the coalescent and the birth–death-sampling model (BDM), in the context of estimating population size and birth rates in a population growing exponentially according to the birth–death branching p...
