in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...

High efficiency of NH3 and H2S removal from waste gases was achieved by the biotrickling filter. Granular activated carbon (GAC), inoculated with Arthrobacter oxydans CH8 for NH3 removal and Pseudomonas putida CH11 for H2S removal, was used as packing material. Under conditions in which 100% H2S was removed, extensive tests to eliminate high concentrations of NH3 emission-including removal char...

AIMS AND METHODS To determine whether volume loading may be beneficial for the performance of ischaemic heart, myocardial ischaemia was created by partial occlusion of the left anterior descending coronary artery (LAD) to reduce the blood flow to 30 approximately 40% of basal level in 11 open chest anaesthetised dogs. Global left ventricular function as well as regional performance were studied...

A mesoporous nickel layer is used as the counter electrode in printable perovskite solar cells. A unique reuse process is realized in such perovskite solar cell devices by repeated loading of the perovskite material. Under standard AM1.5 illumination, the fresh device shows a promising power conversion efficiency of 13.6%, and an efficiency of 12.1% is obtained in the reused devices.

The authors studied the effects of oral loading with 5-HTP on REM fragmentation in a group of alcoholics who were abstinent following acute ethanol withdrawal. Decreased fragmentation was found in the majority of subjects, and those subjects with low baseline REM efficiency (i.e., greater fragmentation) showed more improvement from the drug than did subjects who were less impaired initially. Th...

One of the major problems confronting the search for efficiency in flexible manufacturing systems is the problem of loading and scheduling. This abstract presents a new method to solve such problems. The methodology, which is based on the use of genetic algorithms, allows simple codification of problems and thus facilitates its use. Two kinds of solution are proposed – that is, loading and sche...

Escape analysis can improve the speed and memory efficiency of garbage collected languages by allocating objects to the call stack, but an offline analysis will potentially interfere with dynamic class loading and an online analysis must sacrifice precision for speed. We describe a technique that permits the safe use of aggressive, speculative offline escape analysis in programs potentially loa...

preparation of chitosan (cs) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low cs molecular weight (mw) was investigated in this study. diphtheria toxoid (dt) was used as a model antigen. the emulsion-solidification method was adopted for microencapsulation of dt.  in the first step, following the purification of semi-crude dt by the ion-exchan...

Objective(s) Theophylline, a xanthenes derivative, is still widely used as an effective bronchodilator in the management of asthmatic patients. It is used both as a prophylactic drug and to prevent acute exacerbations of asthma. The aim of study was to formulate and evaluate effect of the microencapsulation of theophylline loaded nanoparticles on the reduction of burst release. Materials and Me...
