Poultry management experts think in terms of tens or hundreds of thousands of birds. They usually prefer systems which require a skilled mechanic as much as a poultry caretaker. As a result, chickens are often seen as some sort of odd little machine that has feathers, squawks, and struggles if caught. This loss of contact between the caretaker and his charges is often associated with lackof rec...

The practical application of elastomeric polydimethylsiloxane coatings for the release of organic adhesives has been advanced at an accelerated rate by applying fracture mechanic principles to what was previously viewed as a complicated surface energy problem. Through the efforts of several research groups, including the work spearheaded by M. Chaudhury, new insights have been gained about the ...

The cellulose sulfate (CS) is a newly developed cellulose derivative. The work aimed to investigate the effect of oleic acid (OA) content on properties of CS-OA film. The process of oleic acid dispersion into film was described to evaluate its effect on the properties of the film. Among the formulations evaluated, the OA addition decreased the solubility and water vapor permeability of the CS-O...

Dioxin-like polychlorinated biphenyls (DL-PCBs) are a class of persistent toxic substances with high potential to accumulate in the soil as an organic pollutant and bioaccumulate humans. The study determined level human health risk twelve (12) DL-PCBs soils from mechanic workshops within Nekede village (NMV), Imo State. In this study, samples (0–15 cm depth) were collected at four different sam...

This paper deals with the estimation of the distance between the solution of a static linear mechanic problem and its approximation by the finite element method solved with a non-overlapping domain decomposition method (FETI or BDD). We propose a new strict upper bound of the error which separates the contribution of the iterative solver and the contribution of the discretization. Numerical ass...
