Application of modified red mud for adsorption of Acid Orang 7 (AO7) dye from aqueous solution: Isotherms, Kinetics studies Abstract: Backgroud: Existence of color is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study is evaluation of adsorption rate of acid orange (AO7) from aqueous solution by act...
Red phosphorus (RP) is one of the most important allotropes of phosphorus with extensive military and civil applications in pyrotechnics. During its maintenance, decomposition of RP generates phosphorus acid family and poisonous phosphine gas. One of the conventional method for evaluation of chemical stability of red phosphorus munitions is evolved phosphine measurement. In the present study, f...
Thalassemia Intermedia; Folic Acid and Vitamin B12 Supplementation. What We Know and What is Needed?
This study presented a mini review on folic acid deficiency and recommendations for its supplementation in thalassemia intermedia (TI). TI is a clinical condition which lies between thalassemia major and thalassemia minor. Although TI patients may not need regular blood transfusion, precise diagnosis and management are critical for the prevention of clinical complications and quality of life im...
In order to enhance bioactive functionalities of ginseng, an acid impregnation processing was applied as a pre-treatment in producing red ginseng. Acid impregnation studies were conducted, and acids (ascorbic, malic, and citric acid) were selected. The optimal concentration of each acid was investigated in this study in terms of ginsenoside contents. The most concerned ginsenoside, Rg3 was incr...
زمینه و هدف: رنگها مواد آلی، با ساختار پیچیده، غالبا سمی، سرطانزا، جهش زا، غیرقابل تجزیه بیولوژیکی و پایدار در محیط زیست می باشند و چنانچه بدون تصفیه وارد محیط زیست شوند باعث به خطر انداختن محیط زیست و سلامت انسان می شوند. هدف از این مطالعه سنتز نانو ذره و بررسی کارایی دو فرآیند هیدروژن پراکسید و هیدروژن پراکسید – نانو ذرات آهن صفر ظرفیتی در حذف رنگ acid red 18 از محیط های آبی است. مواد و روش...
In this paper we estimate the ratio OB stars to red supergiants (OB/R) as a function of the distance from the centre of M 33. We found a gradient of the ratio (OB/R) really exists. Our study is based on a new approach in estimating the errors on the ratio (OB/R). On the other hand, by applying a new correlation technique between OB star candidates and red supergiant candidates in the central re...
The purpose of this study was to determine the effect drying method and bed thickness on physical quality test (moisture content, color), chemical (ash flavonoids, total phenol, carotenoids, ascorbic acid, or vitamin C antioxidant activity) organoleptic Moringa leaf tea. experimental research a Split Plot Design with dryers as main plot subplot. Analysis variance (ANOVA) Duncan's Multiple Range...
We analyzed 33 years of red oak, white pine, and hemlock real stumpage prices—after removing inflationary effects—in southern New England. All real prices fluctuated; the real stumpage prices for white pine appear stable, hemlock decreased, but only red oak stumpage increased meaningfully over the 33-year period. This speaks to the importance of management—including silvicultural prescriptions ...
زمینه و هدف: پسابهای نساجی از جمله آلایندههای محیط زیست به شمار میروند. مشخصه اصلی پسابهای نساجی رنگیبودن آنها است و حاوی انواع آلایندههای آلی و غیر آلی میباشند. بنابراین لازم است که اینگونه پسابها قبل از تخلیه به محیط، با استفاده از روشهای مؤثر مورد تصفیه قرار گیرند. روش کار: این مطالعه یک مطالعه بنیادی- کاربردی میباشد. در این مطالعه کارایی حذف رنگهای Acid Red 18 و Acid Red 14 با ...
SiOC films prepared by the capacitively coupled plasma chemical vapor deposition were analyzed by Fourier Transform Infrared spectroscopy, nanoindentation, capacitance and Xray diffraction patterns to observe the crystallinity and chemical shift of SiOC. The capacitance decreased after annealing process, and the dielectric constant was also decreased by annealing due to the reduction of polariz...
