Predictions of growth are important factors that contribute to the profitability of an operation in poultry production. Modern commercial hybrids have a higher body growth in comparison with the local purebreds. However a niche market for meat and egg poultry production needs to be established using local purebreds to promote biodiversity. The aim of this study was to model the growth response ...

BACKGROUND Bone staples are an accepted method of fixation in foot surgery. They reduce operating time and trauma in surgical procedures. A variety of memory staples are available but their properties compared to standard staples are not known. We carried out a study comparing two popular types of memory staples and a standard stainless steel staple. METHODS Standardized bone models of metata...

Three methods for the laboratory classification of mycobacteria have been proposed. Runyon (1955) used pigment production and rate of growth to define four groups (numbered 1 to 4). Collins (1962) employed growth at 20°C. and 44°C., resistance to thiosemicarbazone, and growth in a synthetic medium to describe four similar groups (assemblies A to D). Marks and Richards (1963) used morphological,...

Unsaturated flow of soils in unsaturated soils is an important problem in geotechnical and geo-environmental engineering. Richards’ equation is often used to model this phenomenon in porous media. Obtaining appropriate solution to this equation therefore provides better means to studying the infiltration into unsaturated soils. Available 5 methods for the solution of Richards’ equation mostly f...

This case tells the true story of a university employee who suffered from color blindness and who, although he had been an exceptional employee, was terminated when he could not read the color screens displayed by the newly installed PeopleSoft system. Moral outrage on the campus initiated a process that ultimately resulted in Hal Richards being offered another position in which his talents cou...

The Richards equation is widely used as a model for the flow of water in unsaturated soils. For modelling one-dimensional flow in a homogeneous soil, this equation can be cast in the form of a specific nonlinear partial differential equation with a time derivative and one spatial derivative. This paper is a survey of recent progress in the pure mathematical analysis of this last equation. The e...

abstract spatial variability of soils makes difficult analysis of soil water flow phenomena especially in a large area such as a watershed. using scaling methods is a solution in variability problems. the objective of this study was to investigate the effect of the non-linear variability on performance of the scaling methods of richards’ equation for modeling infiltration in a watershed. the me...
