in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
This paper aims to investigate mobile banking (MB) usage through the theoretical lens of UTAUT model with its four pillars. The research model will be tested via a hybrid neural networks-based structural equation modeling (SEM-NN) to reveal significant factors. Universal structural modeling (USM) will be then utilized to find the hidden paths and nonlinearity in our research model. To the best ...
In this research miswak leaves, agriculture wastes, available in large quantity in Saudi Arabia, was used as low-cost adsorbent for removing methylene blue (MB) dye. Equilibrium behavior of miswak leaves was investigated by performing batch adsorption experiments. The effects of [MB] 0, pH, contact time and adsorbent dose were evaluated. An alkaline pH (10.6) was favorable to the adsorption of ...
conclusions these outcomes support our theory that rapamycin increases oxidative stress in mcf-7 and mda mb-231 cells but also shows high levels of antioxidant effects, which probably limit the effects of the rapamycin on the same issue in the clinic. methods the mcf-7 and mda mb-231 cell lines were cultivated and treated with rapamycin for 72 hours. the viability of the cells was determined us...
Background: One of the major challenges in orthopedic surgery is the prevention of arthrofibrosis, which can besuccessfully alleviated in its early stages. Many studies suggest the administration of methylene blue (MB) as anaccessible and effective agent for the prevention of post-operation adhesions. The purpose of this study was to evaluatethe efficacy of MB in the preventio...
In this work, aspartic acid- and glycine-functionalized mesoporous silica nanoparticles (Asp-MSNs Gly-MSNs) were successfully prepared applied as adsorbents for removal of methylene blue (MB) from contaminated water. The structure the fabricated nanomaterials was confirmed by nitrogen adsorption/desorption with specific surface area ca. 700 m2/g pore volume 0.9 cm3/g both Asp-MSNs Gly-MSNs. ave...
غشاهای فعال اکسید - احیاء نقش اساسی و مهمی در فرایندهای بیولوژیکی دارند با این حال تعداد کمی از تحقیقات انجام شده در سالهای اخیر به انتقال الکترونها از میان غشاها اختصاص دارد. در این تحقیق، زوج یون چربی دوست [mb+ - clo-4] (mb+متیلن بلو) برای انتقال الکترونها از یک فاز آبی احیاء کننده به یک فاز آبی اکسید کننده که توسط غشاء توده مایع از یکدیگر جدا شده اند، استفاده شده است . بر طبق آزمایشهای اکسید...
Posterior cingulate/retrosplenial cortex (PCC) hypometabolism is a common feature in amnestic mild cognitive impairment and Alzheimer's disease. In rats, PCC hypometabolism induced by mitochondrial dysfunction induces oxidative damage, neurodegeneration and memory deficits. USP methylene blue (MB) is a diaminophenothiazine drug with antioxidant and metabolic-enhancing properties. In rats, MB fa...
prolonged or repeated exposure to cement dust, depending on the duration, level of exposure and individual sensitivity has health implications on the skin, eyes, respiratory and haematological systems. this study assessed cardiovascular disease risk factors and cardiac markers among cement workers of nigerian origin to determine the effects of duration of exposure to cement dust on these parame...
the climate and weather patterns of buffalo (new york, u.s.a.) are strongly influenced by thecity’s proximity to lake erie. total monthly snowfall in buffalo is forecasted using neural network techniques(multi-layer perceptron = mlp) and a multiple linear regression (lr) model. the period of analysis comprises 28 years from january 1982 to december 2009. input data include: zonal wind speed (u-...
