background:pneumonia and respiratory tract infections, is associated with high mortality and complications in humans. current antibiotics are used to treat this infectious disease, but may lead to many problems such as unwanted side effects and resistance to antibiotics. this study investigated the antibacterial activity of the hydro alcoholic extracts of the native medicinal plants peganum har...

ii Acknowledgements I would like to thank my project supervisor, Dr Rob Irving, whose endless patience, advice and assistance has been greatly appreciated. I would also like to thank Dr Helen Purchase for her efforts in securing a faculty scholarship that has enabled me to attend the MSc Information Technology course over the last twelve months.

We combine data from the Latin American Migration Project and the Mexican Migration Project to estimate models predicting the likelihood of taking of first and later trips to the United States from five nations: Mexico, the Dominican Republic, Costa Rica, Nicaragua, and Peru. The models test specific hypotheses about the effects of social capital on international migration and how these effects...

Climate change-related hazards and disasters, known to adversely impact physical and mental health outcomes, are also expected to result in human migration above current levels. Environmentally-motivated migration and displacement may lead to the disruption of existing social ties, with potentially adverse consequences for mobile populations as well as their family members who remain in places ...

The technical information engineering system (TIES) is a computer-assisted methodology to help achieve significant improvements in product quality, production cycle time, and market share. TIES builds on the foundation of quality function deployment (QFD), a systematic method of ensuring that customer demands are accurately translated into appropriate technical requirements and actions. TIES is...

We examine three hypotheses at the foundation of theories concerned with the organization of social space and social solidarity in differentiated groups. The most important of these hypotheses is that interpersonal ties between actors in different positions of a social structure foster social solidarity; however, the theories are silent on the question of whether this effect of interpersonal ti...

The independent helicity amplitudes in the Λb → Λl+l− decay in the standard model and its minimal extension, i.e., with the new vector type interactions, are calculated. We calculate various asymmetry parameters characterizing the angular dependence of the differential decay width for the cascade decay Λb → Λ(→ a + b)V ∗(→ l+l−) with polarized and unpolarized heavy baryons. The sensitivity of t...

Scalar form factor of the nucleon is calculated in the framework of light cone QCD sum rules, using the most general form of the baryon current. Using the result on scalar form factor of the nucleon, the nucleon–scalar σ and a0 meson coupling constants are estimated. Our results on these couplings are in good agreement with the prediction of the external field QCD sum rules method. PACS number(...
