1 This project is subsidized by the natural science fund of Shaanxi Province (serial number of project: 2004E210) Abstract: In this paper, according to practical consideration, a new solar powered rotary solid adsorption refrigerator system adopting activated carbon fibre + ethanol as its adsorption pair has been designed with higher performance. Moreover, the principle of the refrigeration cyc...

OBJECTIVE The post-reconstitution chemical stability and microbial challenge hold time of nonpreserved telavancin for injection was determined using common reconstitution diluents and intravenous (IV) infusion solutions stored at room temperature with light (ambient) or at 2°C to 8°C without light (refrigeration). METHODS Telavancin was reconstituted with 5% dextrose, 0.9% normal saline, or s...

The exergetic analysis is a tool that has been used successfully in many studies aiming a more rational energy consumption to reduce the cost of processes. With this analysis, it is possible to perform an evaluation of the overall process, locating and quantifying the degradation of exergy. This paper applies exergy approach for analyzing the heat exchanger network design and refrigeration of M...

Levetiracetam is a commonly used antiepileptic medication for tumor-related epilepsy. However, the 100 mL intravenous (IV) infusion volume can be burdensome to imminently dying hospice patients. A reduced infusion volume would improve patient tolerability. The purpose of this study was to evaluate the stability of 1000 mg/25 mL (40 mg/mL) levetiracetam IV solution in sodium chloride 0.9%. We pr...

With limited availability of osteochondral allografts, tissue engineered cartilage grafts may provide an alternative treatment for large cartilage defects. An effective storage protocol will be critical for translating this technology to clinical use. The purpose of this study was to evaluate the efficacy of the Missouri Osteochondral Allograft Preservation System (MOPS) for room temperature st...

The Jet Propulsion Lthoratory (JPL) has been involved in cryogenic refrigeration development for the National Aeronautics and Space AdminisUation (NASA) since 1979. Witi the help of NASA, Southern California Gas Company, Ford Automotive, and Aerojet General, we have spun off Ma technology for cmnmerciai air conditioning since 1990. In all, JPL has fabricated and successfully tested the followin...

Thermionic emission in heterostructures is investigated for integrated cooling of high power electronic and optoelectronic devices. This evaporative cooling is achieved by selective emission of hot electrons over a barrier layer from the cathode to the anode. As the energy distribution of emitted electrons is almost exclusively on one side of Fermi energy, upon the current flow, strong carrier-...

OBJECTIVE To compare the fat loss between refrigerator and warm water thawed breast milk. DESIGN Experimental. SETTING Tertiary-care pediatric university hospital. PARTICIPANTS Ninety samples of expressed breast milk were collected from mothers with singleton babies of a gestational age 32-42 weeks. MAIN OUTCOME MEASURES Fat content in fresh breast milk (FM); thawed breast milk by refri...
