There is a growing interest in combining different levels of detail of biological phenomena into unique multi-scale models that represent both biochemical details and higher order structures such as cells, tissues or organs. The state of the art of multi-scale models presents a variety of approaches often tailored around specific problems and composed of a combination of mathematical techniques...
Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...
Biological hydrogen production by anaerobic bacterium, Rhodospirillum rubrum was studied in batch and continuous bioreactors using synthesis gas (CO) as substrate. The systems were operated at ambient temperature and pressure. Correlations available in the literature were used to estimate the gas-liquid mass transfer coefficients (KLa) in batch reactor. Based on experimental results for the con...
enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewa...
in this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. for nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...
Introduction: In protein-protein interaction networks (PPINs), a complex is a group of proteins that allows a biological process to take place. The correct identification of complexes can help better understanding of the function of cells used for therapeutic purposes, such as drug discoveries. One of the common methods for identifying complexes in the PPINs is clustering, but this study aimed ...
activated sludge is an aerobic biological wastewater treatment process. this process has been efficiently and extensively used for the treatment of industrial and municipal wastewaters since about 100 years ago. some drugs such as antibiotics have adverse effects on the bacteria in activated sludge. cefixime trihydrate is a semi-synthetic antibiotic belonging to the third generation of cephalos...
Contact mechanics is related to the deformation study of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. Contact mechanics gives essential information for the s...
Abstract Background: Increase of nitrate concentration in water sources is becoming a serious problem in many parts of the world. Nitrogen containing compounds released into environment can create serious problems, such as eutrophication of water sources and hazard potential to human health, because it has potency of causing methemoglubinemia disease and cancer. Between recommended methods, bi...
