Tea waste (TW) has a protein content of approximately 30% and the potential to replace other sources. However, effect dietary TW supplement is still ambiguous. The objective this study was investigate three levels on performances physiological changes in goats. Nine multiparous crossbred Saanen lactating goats were arranged replicates 3 × Latin square. groups fed with 0, 5, or 10 by weight [wt%...

This paper presents the results of an effort to optimize a conceptual design of a conical (wingedcone) single-stage-to-orbit launch vehicle. The vehicle employs a rocket-based combined-cycle (RBCC) engine capable of four different operating modes ejector, ramjet, scramjet, and rocket. The RBCC engine offers higher engine thrust-to-weight ratios than competing airbreathing engine cycles while ma...

in this research, the steady-state flow filed around a 3d body and rotor configuration of the robin helicopter is simulated. the rotor is modeled by an actuator disk. for this purpose, an annular computational domain replaces the rotor and some modeled source terms are added to the momentum equations. this modeling of rotor considerably speed up computational time. the flow field over this heli...

The snail Trochita trochiformis is a mollusk captured on the coasts of Jalisco and Guerrero Mexican Pacific. Despite its importance in artisanal fisheries, information population parameters still being determined. This research aimed to determine diameter-weight relationship, sex ratio, cohorts, growth this species. Specimens were from October 2019 September 2021. Shell diameter (Sd), total wei...

SCORES (SpaceCraft Object-oriented Rocket Engine Simulation) is an analysis tool being developed for conceptual-level spacecraft and launch vehicle design. Written in C++, SCORES provides rocket thrust and Isp for propulsion system trade studies. Common gateway interface scripts, written in Perl, provide an interface with the World Wide Web. The design parameters used in SCORES are mixture rati...

compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (npr) have been numerically studied with severalturbulence models. the numerical results reveal that, the sst k–ω model give the bestresults compared with other models in time and accuracy. the effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...
