Studies in Ultrafiltration
We are submitting this series of experiments as observed facts, realizing that there are so many uncertainties in this form of indirect observation that great caution must be exercised in drawing conclusions of any kind. The most serious of the possible errors involved is that the active substances which we have studied, the enzyme-the bacteriophage-and the several varieties of virus, may not b...
متن کاملBalanced ultrafiltration, modified ultrafiltration, and balanced ultrafiltration with modified ultrafiltration in pediatric cardiopulmonary bypass.
This study evaluates the effect of balanced ultrafiltration, modified ultrafiltration, and balanced ultrafiltration with modified ultrafiltration on inflammatory mediators in children's open-heart surgery. Eighty children with congenital heart disease were randomly divided into four groups: control group (C group); balanced ultrafiltration group (BUF group); modified ultrafiltration group (MUF ...

چکیده در دنیای پیچیده ی امروز، تغییرات زیادی در زندگی بشری در حال وقوع اند و شاهد رقابت های بسیار فشرده ی جوامع در دستیابی به فناوری برتر و قدرت بیشترهستیم. به نظر می رسد که فرد وجامعه مجبورند به طریقی در وضعیت خویش دگرگونی ایجاد کنند تا از قافله ی علم، فناوری، و پیشرفت عقب نمانند. رشته مطالعات ترجمه نیز از این قاعده مستثنا نیست. علی رغم وسعت روز افزون پژوهش در این حوزه و میان رشته ای بودن مطال...
Preparation, Characterization and Application Studies of PVDF- PS Ultrafiltration Membranes
Polyvinyledenefluoride–polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion technique. Casting solutions were prepared with different compositions of polyvinylidene fluoride (PVDF) and polystyrene (PS) both in the presence and absence of the additive, polyvinylpyrolidone (PVP) using dimethylacetamide as solvent. The effects of compositions of PS and concentr...
متن کاملUltrafiltration I. Ultrafiltration of Electrolytes from Alkali
Ultrafiltration is an important research tool in colloid chemical and in certain types of biological investigation. However, in spite of the many years that ultrafiltration has been used as a research tool, the phase of the subject concerning the ultrafiltra tion of electrolytes from systems containing electrically charged colloids has been lacking in both experimental data and a theoretical ba...
