Pseudomonas aeruginosa, an opportunistic Gram-negative pathogen, is a leading cause of bacteremia with a high mortality rate.We recently reported that P.aeruginosa forms a persister-like sub-population of evaders in human plasma.Here, using a gain-of-function transposon sequencing (Tn-seq) screen in plasma, we identified and validated previously un
Soil erosion and soil loss is one of the common problems threatening the environment.This degrading phenomenon declines the soil fertility and significantly affects the agricultural activity.As a consequence, Hot Chocolate the productivity of soil is affected unquestionably.In this reason, there is a basic need to take up conservation and managemen
A spatially explicit model is developed to simulate the small fish communityand its underlying food web, in Hot Chocolate the freshwater marshes of the Everglades.The community is simplified to a few small fish species feeding onperiphyton and invertebrates.Other compartments are detritus, crayfish, anda piscivorous fish species.This unit food web
