Anomalous seismotectonic interrelationships preceding the 1999 Izmit event , NW Turkey
The 1999 Izmit earthquake (17/08/1999, Mw=7.4) was one of the largest earthquakes in the past 100 years in the northwestern region of Turkey. This earthquake occurred along the Izmit-Sapanca fault within the Northern Anatolian Fault Zone. Variations in the generalized fractal dimensions (Dq) of clustering in time and space, the Gutenberg-Richter b-value, and earthquake frequency (N) are evaluat...
متن کاملVariation Management for Software Production Lines1
Variation management in a software product line is a multi-dimensional configuration management problem. In addition to the conventional configuration management problem of managing variation over time, software product lines also have the problem of managing variation among the the individual products in the domain space. In this paper, we illustrate how to “divide and conquer” the variation m...
متن کاملEffect of PhorbolEsterson IronUptake in HumanHematopoieticCell Lines1
We have investigated the effect of 12-O-tetradecanoylphorbol13-acetate (TPA) on iron uptake into human hematopoietic cell lines K562, U937, and HL-60. TPA inhibited both cell growth and iron uptake by these cell lines. This effect was rapid, which is typical of phorbol esters which are biologically active, and it occurred at very low concentrations of TPA. This effect of TPA was dependent upon ...
متن کاملAberrant Mitochondria in Two Human Colon Carcinoma Cell Lines1
Electron micrographs of CCL237 and FET cells (two slowly growing, differentiated human colon carcinoma lines) revealed enlarged mitochon dria with few cristae. Polarographic measurement of respiratory activity in mitochondria isolated from these cell lines was compared to that of C'V-I cells (a normal monkey kidney epithelial line) and MIP101 cells (another human colon carcinoma line), both of ...
متن کاملComparative Properties of Five Human Ovarian Adenocarcinoma Cell Lines1
We describe the derivation of three human ovarian carcinoma cell lines and the comparison of their properties with two previ ously described cell lines of like histology (SKOV-3 and CAOV3). Two of the new lines (HOC-1 and HOC-7) were derived from separate ascites tumors (at 9-month intervals) of a patient with well-differentiated serous adenocarcinoma of the ovary. The third new line, HEY, was ...
