this study was conducted to evaluate the effects of feeding mash versus pellet with different thermal process on blood metabolites, carcass characteristics and broiler performance. 192 (one-day) cobb broiler chicks were used in a completely randomized design with 4 experimental groups (diets) and 4 replicates of ten chicks each (totally 16 pens). the experimental treatment groups consisted of m...
the abrasion is a significant issue, especially in machining of rigid steels. a functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. the objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
this work studies the biosurfactants production which enables the diesel biodegradation byusing mixed microbial consortia from polluted sites. it was carried out by culturing three microbial consortia(named as xa, xb and xc) obtained from polluted soils, and enriched in diesel as sole carbon source.batchexperiments were done to study the effects of three variables (temperature,hydrocarbon conce...
in this study, bio-based carbon nanotubes (cnts) have received considerable research attention due to their comparative advantages of high level stability, simplistic use, low toxicity and overall environmental friendliness. new potentials for improvement in heat transfer applications are presented due to their high aspect ratio, high thermal conductivity and special surface area. phonons have ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
in this paper, to address the effect of reactor performance and configuration of biodiesel production on subsequent process parameters (including mass & energy consumption, required facilities etc.) two diverse biodiesel production processes (from plant oil) were implemented/designed using aspen hysys v7.2. two series reactors were taken into account in these designs where in the first and seco...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
Der thermische Zersetzungsproze8 bei BMX Die thermische Zersetzung von HMX wurde untersucht oberhalb und unterhalb seines Schmelzpunktes unter Einsatz der Thermoanalytik und der lnfrarotspektroskopie. Der Gewichtsverlust, der auftritt, wenn die Temperatur mit konstanter Geschwindigkeit erhoht wird, laSt sich vier Elementarprozessen zuordnen: lnduktionsperiode, Sublimation, Festphasenreaktion 1....
