We consider convection in an internally heated (IH) layer of fluid that is bounded below by a perfect insulator and above by a poor conductor. The poorly conducting boundary is modelled by a fixed heat flux. Using solely analytical methods, we find linear and energy stability thresholds for the static state, and we construct a lower bound on the mean temperature that applies to all flows. The l...
The toxic element arsenic is widespread in New Zealand’s aquatic and terrestrial environments. Arsenic is ubiquitous in all of the geothermal areas and waterways that fall within or pass-through the Taupo Volcanic Zone, an area in the central North Island that stretches from Mt Ruapehu to White Island (Figure 1). On its way to the surface, super-heated geothermal water dissolves appreciable amo...
background & aim: in recent years, iran and other countries pay special attention to side effects of chemical plants. this interest in plants and their derivatives leads to business of medicinal plants. in caspian region, in forestry projects there are many plant species with medicinal uses from which the locale indigenous used due to traditional experience without any especial processing i...
Background & Aim: Deep heated oils produce toxins that endanger peoplechr('39')s health. The use of herbal supplements along with exercise can improve general health. Therefore, the present study aimed to investigate the effect of aerobic and octapamine training on HSP70 and Caspase 3 protein in brown adipose tissue of rats received w deep heated oils. Methods: 40 male wistar rats after four w...
Introduction: Deep heated oils produce toxins that endanger people's health. The current study aims to investigate the simultaneous effect of aerobic training and Octopamine consumption on the mitophagy of brown adipose tissue after the induction of intoxication through deeply heated oil in male wistar rats. Method: 40 male wistar rats after four weeks of feedi...
Elevated temperature synthesis has been used to generate virtually defect free SiO2 sheathed crystalline silicon nanowires and silica (SiO2) nanospheres which can be agglomerated to wire-like configurations impregnated with crystalline silicon. The SiO2 passivated ~sheathed! crystalline silicon nanowires, generated with a modified approach using a heated Si–SiO2 mix, with their axes parallel to...
We present a high-throughput roll-to-roll (R2R) manufacturing process for foil-based polymethyl methacrylate (PMMA) chips of excellent optical quality. These disposable, R2R hot embossed microfluidic chips are used for the identification of the antibiotic resistance gene mecA in Staphylococcus epidermidis. R2R hot embossing is an emerging manufacturing technology for polymer microfluidic device...
In this research the sol-gel auto-combustion method was used to prepare strontium hexaferrite nanopowder. A solution of distilled water, ferric and strontium nitrates, citric acid, trimethylamine, and n-decyltrimethylammonium bromide cationic surfactant, was heated to form a viscous gel. The gel was heated and then ignited automatically. As-burnt powder was calcined at temperatures from 700 to ...
در این رساله به طراحی یک دوچرخه پرداخته می شود که با حذف رفتار تعویض دنده دستی می تواند به صورت اتوماتیک دنده را به وضعیت مورد نظر تغییر دهد .این امر سبب افزایش تمرکز راکب بر کنترل و هدایت دوچرخه می گردد.همچنین با قابلیت تغییر و تنظیم ابعاد دوچرخه،کاربری آن نیز در مکان های شهری و کوهستانی میسر می گردد. افزایش قابلیت کاربردپذیری ( useable ) دوچرخه در رابطه با تنظیم ابعاد تنه و ارتقا سطح خوشایند...
