A thermodynamic approach based on the hierarchical decomposition which is usually used in mechanical structure engineering is proposed. The methodology is applied to an absorption refrigeration cycle. Thus, a thermodynamic analysis of the performances on solar absorption refrigerators is presented. Under the hypothesis of an endoreversible model, the effects of the generator, the solar concentr...

A modeling study on the energy absorption and heat transfer of concentric nanoparticles under localized surface plasma resonance (SPR) conditions is presented. A generalized theoretical formulation for multi-scattering of electromagnetic waves by multilayered nanoparticle is employed to determine the heat source first, and then starting with the Eigen functions, direct and inverse integral tran...

Tea catechins reduce serum cholesterol concentrations and suppress postprandial hypertriacylglycerolemia in experimental animals and humans. These effects are mainly ascribed to the gallate esters of catechins, (-)-epicatechin gallate (ECG) and (-)-epigallocatechin gallate (EGCG). During pasteurization of tea drinks, tea catechins are epimerized to so-called heat-treated tea catechins such as (...

Strains of Yersinia enterocolitica produce a heat-stable enterotoxin which is positive in the suckling mouse bioassay. Partial purification by a procedure previously worked out for heat-stable Escherichia coli enterotoxin yielded a substance which increases particulate guanylate cyclase activity and short-circuit current and inhibits active Cl-absorption in rabbit ileal mucosa. These effects of...

A new absorption vapor compression distillation was proposed in present research. An open absorption heat transformer has a coupled thermally evaporator and absorber. Distillation of waste water with high content of SiO 2 from heavy oil production. The waste heat of 70 C can be elevated up to 125 C and generate steam of 120 C. The waste heat is able to drive four-effect distillation to produce ...
