Abstract With the process of industrialization, a lot energy is consumed, and low-grade produced in process. To recover low grade heat from flue gas coal-fired power plants, organic Rankine cycle built improves utilization efficiency. Taking six working fluids, R245ca, R245fa, R123, R600, R601, R600a, as an example, referring to exhaust condition 300MW subcritical unit, analysed evaporation tem...

BACKGROUND The effects of cryoinjury were determined simultaneously on the mitochondrial function, motility, morphology and viability of ejaculated human sperm. METHOD Rhodamine 123 (R123) uptake (% of sperm) and stain intensity were used to determine sperm mitochondrial activity before and after cryopreservation from the semen of 50 men attending for infertility investigation. Morphology was...

Triphenylphosphonium hydroethidine (TPP-HE) is a membrane-permeable probe that reacts with superoxide and forms hydroxytriphenylphosphonium ethidium (OH-TPP-E(+)), a fluorescent product that has been previously used in qualitative measurements of superoxide production. In order to develop quantitative methods to measure superoxide, it is necessary to take into consideration the principles that ...

Rat Precision-Cut Intestinal Slices (PCIS) were evaluated as ex vivo model to study the regional gradient of P-gp activity, and to investigate whether the rank order of inhibitory potency of P-gp inhibitors can be correctly reproduced in this model with more accurate IC50 values than with current in vitro models. PCIS were prepared from small intestine (duodenum, jejunum, ileum) and colon. Rhod...

The first demonstration of fabrication of submicron lateral resolution molecularly imprinted polymer (MIP) patterns by photoinduced local polymerization within metal subwavelength apertures is reported. The size of the photopolymerized MIP features is finely tuned by the dose of 532 nm radiation. Rhodamine 123 (R123) has been selected as a fluorescent model template to prove the recognition cap...

This research presents an optimization of a power generation system incorporating ground-cooled condenser. It focuses on the mitigation adverse effects critical parameters such as low mass flow rates and large ground loops. includes investigation different configurations (basic regenerative cycles) working fluids to ascertain their performance system. Three refrigerants, R123, R124 R245fa, were...

In this paper, an exergoeconomic and exergetic sustainability analysis of a dual-pressure organic Rankine cycle (ORC) vapor compression refrigeration (VCRC) driven by waste heat is performed for power generation cooling production. addition, the most suitable fluid couple among thirty-five different pairs was investigated proposed combined system. The results indicate that highest energy utiliz...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

This study focuses on the thermal performance analysis of an organic Rankine cycle powered vapor compression refrigeration for a set working fluids each cycle, also known as dual fluid system. Both cycles are coupled using common shaft to maintain constant transmission ratio one. Eight have been studied and total sixty-four combinations analyzed combined The has performed achieve temperature −1...
