introduction: preventing and starting early treatment of infections in patients whose immunity system is weak due to malignancies like leukemia can reduce mortality. this study aimed to determine microbial and antibiotic resistance patterns in clinical samples of patients with acute leukemia to start early treatment before the results of clinical tests are known. subjects and methods: in this c...
temperature profile during the salting process play an important role in cheese quality since microbial and enzymatic activities, are thereby affected. in this work a three dimensional model was developed for heat transfer in the ultrafilterated cheese by using numerical solution of fourier's second law with finite difference method (explicit scheme) as a function of internal variable (che...
The sustainable recovery of resources from wastewater streams can provide many social and environmental benefits. A common strategy to recover valuable resources from wastewater is to harness the products of fermentation by complex microbial communities. In these fermentation bioreactors high microbial community diversity within the inoculum source is commonly assumed as sufficient for the sele...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
biodecaffeination by pseudomonas pseudoalcaligenes tps8, an isolated strain from tea plantation soil
development of an environmental friendly and cost-effective process for microbial degradation of caffeine to non-toxic compounds are promising to solve the problems of physiochemical extraction of caffeine in the treatment the caffeine containing agro-industrial effluents. thirteen bacterial strains, isolated from tea plantation soils in the north region of iran, were screened to show their abi...
Ziziphora clinopodioides is from the genus of Ziziphora and family of Lamiaceae,which grows in Iran and Turkey. This study was conducted to preserve the chemical and microbial quality of trout fish burger during storage using Ziziphora clinopodioides essential oil (ZEO) individually and in combination with nisin. Firstly, the chemical composition of ZEO was deter...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles. the present study aimed at the comparative study of silver nanopartic...
