The In vitro antibacterial activity of Leptadenia pyrotechnica roots and fruits extracts was investigated against Staphylococcus epidermidis and S. aureus by using agar-well diffusion assay. Plant samples were collected from Thal desert of Pakistan and eight different solvents viz. n-hexane, chloroform, acetone, ethylacetate, butanol, methanol, ethanol and water were used for the preparation of...

Introduced reindeer, Rangifer tarandus, overexploited lichen-rich plant communities on St. Matthew Island in the Bering Sea. A die-off of the reindeer followed, exacerbated by extreme weather in 1964, resulting in extirpation of the reindeer. A similar pattern of removal of lichens as major components of plant communities has occurred following introductions of reindeer to other islands at high...

economists, sociologists and others have come to-this conclusion that the only element that eventually will determine the orientation of development, economic and social development of any country is the human resource. hence the physical capital and natural resources are not determinant one in this respect. the development of human resources which is the result of younger generation education ...

We are HIV. Our family is ancient. Out of Africa, Monkey to man, From the trees and forests, To the towns and cities. We are here. For we are HIV, we are legion. Our children are billions, Our home, in your defenses, In your blood, your brain, Your saliva, your semen. We are everywhere. For we are HIV, we are immortal. We are part of you, And you of us, We live with you, but May not die with yo...

This study is conducted to developed innovative production planning and control strategies to manufacturing industries so as to improve production performance and competitiveness of basic metal sectors Though the study was conducted through field observation and questioner used as primary data and literature review on research articles, books, and electronic-sources which used as secondar...

For a field K, rational function φ ∈ K(z) of degree at least two, and α ∈ P(K), we study the polynomials in K[z] whose roots are given by the solutions in K to φ(z) = α, where φ denotes the nth iterate of φ. When the number of irreducible factors of these polynomials stabilizes as n grows, the pair (φ,α) is called eventually stable over K. We conjecture that (φ, α) is eventually stable over K w...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...
