background and objectives: coagulase negative staphylococcus (cons) is frequently isolated from blood cultures but their significance is difficult to interpret. cons bacteria which are often previously dismissed as culture contaminants are attracting greater importance as true pathogens in the past decades. clinical evaluation of these isolates suggests that although there is a relative increas...
job definition
Skeletal deformities seriously relegate the biological performance of fish. The frequency of occurrence of different types of meristic variations and skeletal deformities were seen in the population of mahseer fish, Tor putitora, in two main reservoirs; Korang Stream, Islamabad and Dhobi Ghat Stream, Hassan Abdal. A total of ninety-five fish were caught randomly, forty-five from the unpolluted ...
The weird and wonderful variety of bugs that live in streams is more than cool—it a great scientific tool. mixture helps scientists understand water quality, which means whether the clean or dirty. Two kinds tools translate bug into measures stream health. One called multimetric index; other an observed-to-expected index. index “speaks bug” to us. It uses preferences for food habitat, tolerance...
Novel fabrication techniques and polymer systems are being explored to enable mass production of low cost microfluidic devices. In this contribution we discuss a new fabrication scheme for making microfluidic devices containing porous polymer components in situ. Contact lithography, a living radical photopolymer (LRPP) system and salt leaching were used to fabricate multilayer microfluidic devi...
