در این پژوهش قابلیت سه فرایند اکسیداسیون پیشرفته uv/tio2، uv/h2o2 و uv/o3 در حذف رنگزای اسید قرمز 14 که یکی از پر مصرف ترین رنگزاها در صنایع نساجی است، در محیط آبی بررسی شد. در فرایند uv/tio2 بیش از 90 درصد رنگزا با غلظت 40 میلی گرم در لیتر در شرایط بهینه با ph برابر 3، در مدت زمان 30 دقیقه، توسط 4/0 گرم در لیتر دی اکسید تیتانیم و شدت تابش uv 30 وات حذف شد. همچنین در فرایند uv/o3 در شرایط بهینه...
در میان طیف گسترده دیدگاه های موجود در خصوص نقش دولت در اقتصاد، یک دیدگاه میانه مهم ترین اولویت دولت در اقتصاد را ایجاد زیربناهای نهادی معرفی می کند. این نقش مهم دولت در کشورهای در حال توسعه و به ویژه کشورهای وابسته به درآمدهای نفتی، بسیار حیاتی تر از کشورهای توسعه یافته است. در ایران آغاز سده چهاردهم ﻫ.ش بسیاری از موانع رشد به وضوح قابل مشاهده است. مهم ترین آن ها ضعف چارچوب های نهادی مناسب برا...
The family of 14-3-3 proteins has emerged as critical regulators of diverse cellular responses under both physiological and pathological conditions. To gain insight into the molecular action of 14-3-3ζ in multiple myeloma (MM), we performed a systematic proteomic analysis of 14-3-3ζ-associated proteins. This analysis, recently developed by Matthias Mann, termed quantitative immunoprecipitation ...
In this report two non consanguineous children are presented with strikingly similar phenotypes confirming the existence of a characteristic phenotype due to a ring chromosome 14 formation.
In an earlier paper by Linus Pauling titled "Genetic and Somatic Effects of Carbon-14" (1), it is established that this by-product of nuclear explosions might induce greater genetic and somatic damage than previously assumed. Furthermore, Pauling states that the damage produced by carbon-14 that is incorporated into genetic material is responsible for only 10% of the total genetic damage genera...
A liposomal delivery system was developed in an attempt to prolong ocular levels of 5-fluorouracil for glaucoma filtering surgery. The pharmacokinetics of the 5-fluorouracil liposomal delivery system were studied in normal pigmented rabbits with 5-fluorouracil labelled with carbon-14 (C-14). 14C 5-fluorouracil was incorporated into the liposomes at a concentration of 10 g/l and injected subconj...
OBJECTIVES University students in general face multiple challenges, which may affect their levels of perceived stress and life satisfaction. Chinese students currently face specific strains due to the One-Child Policy (OCP). The aim of this study was to assess (1) whether the levels of perceived stress and studying-related life satisfaction are associated with only-child (OC) status after contr...
Artifacts of cold-hammered native gold have been discovered in a secure and undisturbed Terminal Archaic burial context at Jiskairumoko, a multicomponent Late Archaic-Early Formative period site in the southwestern Lake Titicaca basin, Peru. The burial dates to 3776 to 3690 carbon-14 years before the present (2155 to 1936 calendar years B.C.), making this the earliest worked gold recovered to d...
Medical assistance in dying: Examining Canadian pharmacy perspectives using a mixed-methods approach
Background Canada legalized assisted dying with the passing of Bill C-14, Medical Assistance in Dying (MAiD), in June 2016. This legislation has implications for health care professionals participating in MAiD. This research aims to understand the effect that MAiD has on pharmacists and pharmacy technicians in Canada. Methods We conducted a thematic document analysis of pharmacy guidelines, p...
