Plasmapheresis is one of the methods of extracorporeal blood purification used for many decades for the treatment of different kidney and extrarenal diseases, mainly of autoimmunological nature. The main disadvantage of this method is the lack of selectivity and the risk of infections associated with plasma used for supplementation. Hence, the efforts are made to establish an alternative blood ...

Green fluorescent protein (GFP) is a useful biomolecule in biotechnology; however, its price makes widespread application prohibitive. To overcome this issue, recently, the use of aqueous two-phase systems (ATPS) for GFP purification was proposed as an alternative platform to reduce processing costs. Aligned with goal, study performed bioprocess modelling coupled economic analysis using softwar...

Clean water is an invaluable need for the residents of Pemangkih Tengah village. The in village actually blackish color, because area this located a location with peaty soil and acid soil. To overcome problem, it necessary to have purification device using materials that are easily available. Materials available include rice husks, sand, gravel palm fibers. goal people more enthusiastic about m...

This thesis had three different objectives: i) to discover different methods for kraft lignin purification that could be used alongside acid precipitation, ii) test the most suitable treatment on laboratory scale and evaluate the potentiality of this method as a kraft lignin purification method, and iii) to compare the feasibility of lignin purification alongside the acid precipitation compared...

this research aims to study the relationship between the components of quality costs and quality in company. the relationship between the components of quality costs and quality in company has been studied separately for materials, manpower, machinery, and whole of company. in this study, traditional method was used to collect quality costs and paf model was used to determine the components of ...

New nanoscale hetero-oligonucleotide tiles are assembled from DNA, RNA and morpholino oligos and purified using size exclusion filtration. Homo-oligonucleotide tiles assembled from RP-cartridge processed DNA oligos are purified by nondenaturing gel electrophoresis. These tiles' purity and homogeneity are demonstrated by gel electrophoresis and their incorporation into two-dimensional arrays vis...

this study aimed at identifying components of the household health costs.this study was a qualitative research conducted in two main phases. the first phase consisted of interviews with sample households selected in eight provinces of iran. they were to identify components of the household health costs. in the second phase, components were determined as direct, indirect and intangible based on ...

Because human societies have not closed solid waste loops in the production and consumption of gaDds,methods of solid waste treatment are still necessary. In this work the author examines two modem methods of municipal solid waste (MSW) treatment as employed in Sweden. These methods are waste treatment in a bioreactor cell and MSW incineration. The investigation analyzes the critical economic c...

flocculation processes during estuarine mixing can reduce the elemental concentrations of river water. in the present investigation, natural flocculation processes concept is used to reduce the elemental contents of industrial wastewater. for this purpose, various amounts of saline water were added to an artificial industrial wastewater with known concentrations of heavy metals. the results of ...

Isolation and characterization of the surface active components from the crude biosurfactant produced by Streptococcus thermophilus A was studied. A fraction rich in glycolipids was obtained by the fractionation of crude biosurfactant using hydrophobic interaction chromatography. Molecular (by Fourier transform infrared spectroscopy) and elemental compositions (by X-ray photoelectron spectrosco...
