air conditioning refrigerant r134a has value of global warming potential (gwp) 1300, which is much higher than mac directive (gwp below 150) passed in july 2006. this prompted a search for alternative refrigerant with gwp value less than 150. r1234yf is a new refrigerant which has lower gwp value of 4. effect of blower speed has been compared and flammability issue of r1234yf has been addressed...

j-Ieart size was measured radiographically before and after single or double homograft valve replacement in 69 consecutive patients. Thirty patients had aortic valve replacement, 25 mitral, and 14 both aortic and mitral valve replacement. For aortic valve replacement a fresh unsupported homograft was inserted in the subcoronary position, while for mitral valve replacement afresh semilunar homog...

Data Grid is a new kind of data management infrastructure. To improve access efficiency, large amounts of data on Data Grids need to be replicated in the form of replicas at distributed sites. Due to the limited storage capacity, a good replica replacement algorithm is needed. This paper proposes a replica replacement algorithm based on value-cost prediction, which achieves a good balance betwe...

OBJECTIVE To evaluate the impact of enzyme replacement therapy for Gaucher Disease on clinical and laboratory parameters after two, five and ten years of treatment. METHODS Data were collected from patient records and analyzed using BioEstat software (version 5.0). Student's t-test, Analysis of Variance (ANOVA), Wilcoxon test and Kruskal-Wallis test were used for statistical analysis. Hepatom...
