Strain distribution of Al 1100 was numerically investigated during cyclic expansion extrusion (CEE) process using finite element method (FEM). Die angle, corner fillet radius and die chamber diameter were considered as die parameters and friction factor and number of passes as process parameters. The effects of these parameters were investigated on the effective strain and strain homogeneity in...

the purpose of this study was to investigate the effect of polyvinyl chloride vacuum packaging(170 micron thickness) on omega 3 and omega 6 contents of carp fillet at -18 ° c during 180 day storage. the tests were done with the use of gas chromatography. total content of w6 in fresh fish was 18.21%. after 180 day storage the amount of w6 in control sample changed to 14.85% but for vacuumed fill...

the accuracy of stereolithography (sl) product is very essential for meeting the intended functional applications. the parameters like layer thickness, hatch spacing, hatch overcure contribute significantly to the accuracy of the sl parts. in this paper an attempt has been made to identify the process parameters that influences on the accuracy of the parts made with ciba tool 5530 and optimize ...

The nutritional quality of tilapia fillet is characterized by low omega-3 polyunsaturated fatty acids (n-3 PUFAs). objective the present study was to evaluate effect different dietary concentrations chia (Salvia hispanica) and flaxseed (Linum usitatissimum) meal on acid content (Oreochromis niloticus) fillet. Six experimental diets incorporating 5, 10, 15% or meals, respectively, were given fis...

This paper considers the possibility to use various fillings – smoked chicken breast fillet, lightly salted salmon with cottage cheese, imitation crab meat and mayonnaise in manufacture of rice balls named “onigiri”, using porphyry algae, their effect on quality indicators samples obtained. To achieve this goal, onigiri prepared introduction types were studied. In Japanese cuisine recipe classi...

Gas turbine engines are used in a variety of power generation applications, including providing thrust for the F-35 Lightning II Joint Strike Fighter, turning electrical generators in combined-cycle power plants, and powering the M1 Abrams Main Battle Tank. In the high-temperature region of the turbine section, a complex vortical (swirling) flow present near the junction of a turbine airfoil an...

A 15-wk study was conducted to evaluate the effect of supplemental menhaden fish oil levels and feeding duration on growth performance and tissue proximate and fatty acid (FA) compositions of juvenile channel catfish, Ictalurus punctatus. Dietary fish oil levels had no effect on final weight gain, feed efficiency, and survival of channel catfish. Tissue lipid contents were directly correlated t...

Gas turbine engines have a high power-to-weight ratio, making them ideal for generation of aircraft thrust, and can have excellent electrical power generation efficiencies when used in a combined cycle power plant. A complex vortical flow at the junction of the nozzle guide vane airfoil and its casing (endwall) in the turbine section tends to decrease aerodynamic efficiency and increase metal t...

We investigate (via finite-element analyses) the factors that may affect the accuracy of micro-compression measurements (see, e.g., Uchic et al. [Uchic MD, Dimiduk DM, Florando JN, Nix WD. Science 2004;305:986]). Based on these simulations, we suggest guidelines for the development of accurate micro-compression experiments in terms of fillet to post radius ratio, post aspect ratio, post taper, ...
