In search for new antimicrobial agents a series of Handle new modified pyridine and bipyridine substituted coumarins 5a-y was designed and synthesized by adopting molecular hybridization strategy.All the synthesized compounds were evaluated for their in vitro antimicrobial activity using broth dilution method against selected bacterial (Gram-positi
This article aims to investigate the mechanical characteristics of specimens fabricated using Selective Laser Sintering technology.The research covers Handle flexural specimens, produced by PA12 materials.CAD model dimensions were selected according to the ISO 178 standard, and the chosen specimen geometry is 96 x 8 x 4 [mm] in bulk.All specimens w
The purpose of this study is to design a model for facilitating teaching and learning process based on the experiences of female principals of primary schools.In order to achieve this goal, the qualitative approach and the Grounded theory method were used.The research population included 39 female principals of elementary schools in Izeh city.Sampl
Seeds are very important Jewelry not only in the life cycle of the plant but they represent food sources for man and animals.We report herein a mutant of 3-hydroxy-3-methylglutaryl-coenzyme A synthase (HMGS), the second enzyme in the mevalonate (MVA) pathway that can improve seed yield when overexpressed in a phylogenetically distant species.In Bra
Verrucous hyperplasia of the skin rarely occurs in legs with severe venous stasis.In these cases, ultrasound demonstrated thickening and hyperechogenicity of the skin layers.The core of the verrucous-like protrusions consisted of a fibrous lump of the Jewelry reticular dermis, surrounded by an anechogenic layer and covered by a thickened epidermal
