In this study, the incorporation of a flexible baffle structure at base microelectronic channel is examined to determine its impact on thermal and fluid dynamics. The investigation covers two configurations: case 1, where heat source situated top section microchannel, 2, with placed bottom. To cool electronic component, nanofluid consisting water aluminum oxide (Al2O3) nanoparticles, in concentrations varying from 0% 6%, injected into exhibiting periodic velocity profile inlet. governing...
Having high cytotoxicity cell line effect, Cinnamomum zeylanicum Blume essential oil offers a novel approach to the chemotherapy treatment. In order enhance its quantity/purity, experimental conditions produce should be more exploited. Steam distillation was used isolate oil, and conditions’ optimization carried out with surface-response methodology. The maximum amount (2.6 g/100 g d.b.) obtained under minimum condensation water flow (0.8 mL/min), sample size of 6.5 cm, saline solution...
The textile industry produces high volumes of colored effluents that require multiple treatments to remove non-adsorbed dyes, which could be recalcitrant due their complex chemical structure. Most the studies have dealt with biodegradation mono or diazo dyes but rarely poly-azo dyes. Therefore, aim this paper was study a four azo-bond dye (Sirius grey) and optimize its decolorization conditions. Laccase-containing cell-free supernatant from culture newly isolated fungal strain, Coriolopsis...
This study aimed to maximize biomass concentration, productivity and biochemical composition of the marine microalga Tetraselmis sp.In current study, Box-Behnken Design was used model effect NaNO3, NaH2PO4, metals vitamins in F/2 medium on growth, total chlorophylls, carotenoids starch contents. The chlorophylls content quantified by spectrophotometry. FT-IR spectroscopy estimate compositions sp. grown under both optimized culture for production standard medium.Finalized NaNO3 (1.76 mM),...
This study aimed to develop nutritious, gluten-free bread with high quality characteristics using a mixture of chickpea, carob and rice flours as substitutes wheat flour. To optimize the formulation, Box-Behnken experimental design was conducted evaluate effect corresponding flour blend addition, proofing time water amount addition on physicochemical, technological sensory properties obtained formulated bread. The optimized formulation calculated contain 70% 100% water, 40 minutes. produced...
In this work, a novel enhanced model of the thermophysical characteristics hybrid nanofluid is introduced. An innovative kind fluid called has been engineered to increase heat transfer rate and performance thermal system. A growing trend in scientific industrial applications pushed researchers establish mathematical models for non-Newtonian fluids. parametric study on theheat flow Williamson based AA7075-AA7072/Methanol overincessantly moving thin needle under porosity, Lorentz force,...
Lately, microalgae have been used as natural additives in fish-transformed products to improve their nutritional quality. In this research, the effects of adding Spirulina platensis at concentrations 0.5, 1 and 1.5% w/v on both texture sensory characteristics canned burgers were studied. fact, addition fish improves composition. Compared results other burger treatments, treatments that contain 1% had better properties (p < 0.05). Besides, these showed higher swelling ability well water...
The olive mill wastewater (OMW) treatment process is modeled and optimized through new design of experiments (DOE). first step the coagulation–flocculation using three coagulants (modeled with mixture design) followed by photo-degradation (modelled full factorial design). Based on this methodology, we successfully established a direct correlation between system’s composition during conditions photo-catalytic degradation step. Three are used in study, Fe3+ solution, lime, cactus juice, two...
Abstract This work deals with the optimization of culture conditions Bacillus invictae AH1 in order to increase production level proteolytic activity. Response‐surface methodology (RSM) was applied for most significant fermentation parameters (concentration wheat bran and K 2 HPO 4 /KH PO ) that were earlier identified by Plackett–Burman Design from seven possible factors. A central composite design used quadratic regression model producing active protease built. maximum activity reached...
Kinetics of aqueous extraction polyphenols from carob (Ceratonia siliqua L.) have been performed in different conditions (Temperature = 40 and 60C; solid–liquid ratio 1:3 1:19 without with ultrasonic assistance (100W)). The effects various parameters were studied using an experimental design. final yield was modelled as a first order polynomial model: (p < 0.10). An HPLC analysis showed that the major component is galic acid ultrasound has no effect on degradation phenols. Eight models...
The present study was focused on the optimization of yield essential oil extraction from leaves Lawsonia inermis, and determination chemical composition, antioxidant activities, lipid peroxydation antiproliferative effects.Henna (HeEO) were extracted by hydrodistillation; identification composition done GC/MS method. HeEO analyzed for power in: (1) system DPPH test, ABTS test total activity test; (2) in biological tests (MDA DC) cells culture. cytotoxicity effects assessed using MTT assay...
Microalgae have been used as natural ingredients to produce functional and nutritional food products. The impact of the addition Chlorella minutissima, Isochrysis galbana, Picochlorum sp. at concentrations 0.5, 1, 1.5% w/v on texture sensory attributes canned burgers were investigated. results show that carp formulations containing 1% microalgae significantly better classification performance for many textural parameters compared rest formulations. Also, these treatments had higher swelling...
In this study, a 2D numerical analysis was conducted to investigate electro-thermo-capillary convection in enclosure filled with dielectric fluid. The had free top surface and subjected buoyancy electrical forces. study considered strong unipolar injection of electric charge (C = 10), mobility number (M Prandtl (Pr 10). Calculations were performed for various thermal Rayleigh numbers (Ra) ranging from 5000 50,000, Marangoni (Ma) varying −5000 (T) 100 800. coupled equations governing the...
