126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...
Due to the importance of power generation cycles including combined cycle, many studies have been done in recent years and many researchers have been tried to optimize these cycles by using of existing methods. In this study, the Water-Ammonia cycle is investigated in the combined-cycle of the Water-Ammonia, working dual Water-Ammonia mixture is used as the works fluid. This cycle can be used f...

background: our study compares the efficacy of the combined contraceptive vaginal ring to oral contraceptive pills (ocps) for hypothalamic-pituitary-ovarian (hpo) axis suppression in egg donor in vitro fertilization (ivf) cycles. methods: our retrospective cohort study includes patients from the center for assisted reproduction (care) in bedford, texas undergoing ivf cycles as egg donors from j...
Since ordinary gas turbine cycles in actual condition comprise simple cycle, regenerative cycle, reheat cycle and intercooler cycle between high pressure and low pressure compressors, these cycles include 16 combined cycles by combining with a Rankine cycle that consists of three organic fluids and steam. In the present work, the thermodynamic analysis of the above combined cycles with three or...
In this paper the ratcheting behavior of carbon steel(ASTM A106B) and stainless steel(304L) elbows is studied under steady internal pressure and in-plane external moments at frequencies typical of seismic excitations. The finite element analysis with the nonlinear isotropic/kinematic (combined) hardening model has been used to evaluate ratcheting behavior of the elbows. Material parameters have...
