a preliminary design of a polygeneration system (combined cooling-heating-power plant with a desalination unit), is proposed for a tourist resort located on the spanish coast. the well-known trigenerationconcept is enhanced to the included production of desalted water, considering for the purpose three different options: reverse osmosis (rodp), multi-effect (medp) and a combination of rodp and ...

BACKGROUND AND PURPOSE We conducted a pilot feasibility and safety study of selective brain cooling with intra-arterial infusion of cold saline combined with endovascular reperfusion for acute ischemic stroke. METHODS Patients with large-vessel occlusion within 8 hours after symptom onset were enrolled. All patients received intra-arterial recanalization combined with infusion of cold isotoni...

The present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. The present first-moment closure model consists of a higher level of turbulent heat flux modeling in which two additional transport equations for temperature variance kθ and its dissipation rate εθ are ...

A novel solar-based combined system which is consisting of a concentrated PV, a double effect LiBr-H2O absorption chiller, and a Proton Exchange Membrane (PEM) is proposed for hydrogen production. A portion of the received energy is recovered to run a double effect absorption chiller and the rest is turned into electricity, being consumed in the PEM electrolyzer for hydrogen producti...

In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...

This study presents a theoretical analysis of a new combined cooling, heating, and power cycle by the novel integration of an organic Rankine cycle (ORC), an ejector refrigeration cycle (ERC), and a heat pump cycle (HPC) for producing cooling output, heating output, and power output simultaneously. Three different working fluids—namely R113, isobutane, and R141b—have been used in power, ref...

Therapeutic hypothermia improves clinical outcome in patients with global cerebral ischemia after cardiac arrest and in newborns with hypoxic ischemic encephalopathy. Hypothermia also seems promising in other cerebrovascular diseases, for example, ischemic and hemorrhagic stroke. In experimental models, the sooner hypothermia was initiated, the more distinctive neuroprotection was. Although cli...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...
