Abstract The cumulative installed capacity of photovoltaics has passed 1 TW, which about two-thirds were only in the past five years. Many these new installations incorporate novel module and cell designs that have not yet been subjected to long-term in-field characterization. Indoor accelerated stress testing historically a valuable methodology identify fault mechanisms, estimate degradation r...

background cholera is a severe diarrheal illness caused by vibrio cholerae, which produces a virulence factor named el tor hemolysin encoded by the hlya gene. objectives this study meant to analyze the phenotypic characteristics and presence of hlya gene in v. cholerae isolated from patients in iran. the hlya gene which codes for hemolysin, plays an essential role in manifestation of cholera ,a...

calcium-binding proteins play essential roles in the cell. one important class of calcium-binding proteins is the annexin family. this is a family of 13 proteins, which binds to phospholipids in a calcium-dependent manner. osteosarcoma cell line (mg-63) is a transformed cell that has many characteristics of the differentiated cell, such as a considerable serum dependency in its growth rate. usi...
