The aerobic granular sludge process is a promising technology for the removal of nutrients and organic contaminants from wastewater. However, a large amount of the sludge is often washed out during the start-up of granular reactors, which results in reduced process performance and a protracted start-up phase. In this study, the possibility of a rapid start-up of the nitrification process throug...

background and objectives:infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. the aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (pe). materials and methods: in this cross sectional study, 1210 samples with exudative features were cultured for poss...

despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (bm) before organism growth in the culture medium-are missing. therefore cerebrospinal fluid (csf) lactate levels were evaluated as a possible means of differentiating the two clinical entities. this was a retrospective study. pat...

introduction: to report our experience with a large series of surgical procedures for removal of cerebellopontine angle (cpa) tumors using different approaches.   materials and methods: this was a retrospective analysis of 50 patients (mean age, 49 years) with cpa tumors (predominantly acoustic neuroma) who underwent surgical removal using appropriate techniques (principally a translabyrinthine...

With the development of life and industry, nutrients in sewage increased gradually. The emerging symbiotic system algal bacteria has remarkable effect removing such as nitrogen phosphorus. In this paper, influence phosphorus on bacteria-algal consortia absorption mechanism by interaction were analyzed, a variety methods for studying summarized, mainly using isotope tracer technology to study re...
