In the present study formulation and characterization of spray drying microspheres of azithromycin dihydrate, (prescribed extensively in solid dosage forms) in a sustained release form to overcome drug resistance, and dosing non-compliance in pediatric patients. So, the purpose of this research was to formulate sustained release microspheres of azithromycin dihydrate using chitosan as a carrier...

This paper presents the study on the effect of low κ stacked layer, chip pad design structures, and shift pad design of a large die size Cu/low κ (BD) chip for improving assembly and reliability performance on organic buildup substrate FCBGA (FlipChip Ball Grid Array). Bump shear characterization has been performed on the integrity of different stacked layer and pad structure, supported by bump...

A cDNA library was synthesized from maize anaerobic root mRNA and screened with cDNA specific to the anaerobically induced Zea mays cytoplasmic aldolase. At least 1% of the cDNA of the library corresponded to maize cytoplasmic aldolase. The sequence of four overlapping cDNA clones encoded a protein of molecular weight 38,611 homologous to aldolase. These cDNAs were polymorphic at three bases an...

Recent investigations have revealed that Pb-free solder joints may be fragile, prone to premature interfacial failure particularly under shock loading, as initially formed or tend to become so under moderate thermal aging. Depending on the solder pad surface finish, different mechanisms are clearly involved, but none of the commonly used surface finishes appear to be consistently immune to embr...

Cassava is a staple food for approximately 800 million people in tropical countries. The tuber which comprises mainly starch also contains high concentration cyanogenic glycosides which give rise to the hydrocyanic acid by enzymatic hydrolysis. The purpose this research therefore is to investigate the detoxification potential of fermentation, on the toxic (cyanide) content of cassava tuber. The...

The pattern and schedule of histone synthesis in unferti l ized eggs and early embryos of the sea urchin Strongylocentrotus purpuratus were studied using two-dimensional gel electrophoresis. After ferti l ization there is an abrupt change in the pattern of histone variant synthesis. Al though both cleavage-stageand c~-histone mRNA are stored in sea urchin eggs, unferti l ized eggs synthesize on...

Integrated circuit packaging and their testing is well advanced because of the maturity of the IC industry, their wide applications, and availability of industrial infrastructure.[1,2] This is not true for MEMS with respect to packaging and testing. It is more difficult to adopt standardized MEMS device packaging for wide applications although MEMS use many similar technologies to IC packaging....
