Review Article: A trends of Salmonella and antibiotic resistance

Salmonellosis has become a major problem in developed and developing countries. It also represents an important public health concern worldwide.  As such, due to intense interest Salmonella research has gained great concern from scientific communities as well as the general public.  The purpose of this review is to discuss the historical perspective, classification and nomenclature, antibiotic and antimicrobial definition, mechanism of antibiotic resistance, integrons and antibiotic resistance Salmonella

ESTIMATED DURATION OF THE SUBSURFACE REDUCTION ENVIRONMENT PRODUCED BY THE SALTSTONE DISPOSAL FACILITY ON THE SAVANNAH RIVER SITE.

The formula for Savannah River Site (SRS) saltstone includes {approx}25 wt% slag to create a reducing environment for mitigating the subsurface transport of several radionuclides, including Tc-99. Based on laboratory measurements and two-dimensional reactive transport calculations, it was estimated that the SRS saltstone waste form will maintain a reducing environment, and therefore its ability to sequester Tc-99, for well over 10,000 years. For example, it was calculated that {approx}16% of the saltstone reduction capacity would be consumed after 213,000 years. For purposes of comparison, a second calculation was presented that was based on entirely different assumptions (direct spectroscopic measurements and diffusion calculations). The results from this latter calculation were near identical to those from this study. Obtaining similar conclusions by two extremely different calculations and sets of assumptions provides additional credence to the conclusion that the saltstone will likely maintain a reducing environment in excess of 10,000 years

Fast and Efficient Compressive Sensing using Structurally Random Matrices

This paper introduces a new framework of fast and efficient sensing matrices for practical compressive sensing, called Structurally Random Matrix (SRM). In the proposed framework, we pre-randomize a sensing signal by scrambling its samples or flipping its sample signs and then fast-transform the randomized samples and finally, subsample the transform coefficients as the final sensing measurements. SRM is highly relevant for large-scale, real-time compressive sensing applications as it has fast computation and supports block-based processing. In addition, we can show that SRM has theoretical sensing performance comparable with that of completely random sensing matrices. Numerical simulation results verify the validity of the theory as well as illustrate the promising potentials of the proposed sensing framework
