Despite the potential of cellular RNA as a tool for the study of bacterial activities in natural environments, cellular RNA has rarely been measured because of methodological limitations. In a previous study, we quantitatively analyzed single-cell RNA content with multiple 16S rRNA-targeted fluorescent probes. In the present study, we explore the potential of this approach with 12 samples of na...

Background: Urinary tract infection (UTI) remains a common clinical problem in both the community and health care associated settings. In Pakistan, this is also a common issue and each patient should be carefully assessed to ensure that a correct diagnosis is made and that antimicrobial therapy is appropriately prescribed. UTI is a common problem and it effect’s both gender and all ages. Aim: T...

There are more than one million microbial cells in every drop of seawater, and their collective metabolisms not only recycle nutrients that can then be used by larger organisms but also catalyze key chemical transformations that maintain Earth's habitability. Understanding how these microbes interact with each other and with multicellular hosts is critical to reliably quantify any functional as...

Conformal Killing vectors (CKVs) preserve the spacetime metric up to a factor. Homothetic vectors and Killing vectors are special cases of CKVs. Classification of some classes of spacetimes on the basis of CKVs give interesting results showing how homothetic and Killing vectors which form subsets of the set of CKVs can be recovered as a result of the above classification. ∗On leave from: Centre...

Lie derivatives of various geometrical and physical quantities define symmetries and conformal symmetries in general relativity. Thus we obtain motions, collineations, conformal motions and conformal collineations. These symmetries are used not only to find new solutions of Einstein’s field equations but to classify the spaces also. Different classification schemes are presented here. Relations...

SIMD computers are a class of massively parallel computer in which many processors simultaneously execute the same instructions on their own data. This paper briefly reviews the history of the development of SIMD computers, and gives an overview of the state of the art in SIMD computers by comparing the origins, hardware, software, performance, price and marketing of three commercially availabl...
