We present an analysis of a sequence of light curves of the RS CVn-type binary II Pegasi extending from 1974 to 1998. The distribution of the spotted area versus longitude is derived by Maximum Entropy and Tikhonov regularized maps, assuming a constant spot temperature (Lanza et al. 1998a). The spot pattern on the active K2 IV star can be subdivided into a component uniformly distributed in lon...

abstract shah jahan, based on structural zone is located in south of kapedagh and in eastern side of aladagh mountains in 37◦ till 37◦25' northern latitude and 57◦30' till 58◦30' eastern longitude of northeastern part of iran. geomorphologic and tectonic elements show that this area is partly young and mountains can be affected highly by geomorphologic and hydrologic elem...

The Udhampur district lies in the northernmost portion of India, approximately at 75” 7’ to 75” 10’ longitude east and 33” 54’ to 33” 57’ latitude north in the State of Jammu and Kashmir. The total area of the district is 2549 km2; it has a hilly topography ranging from 300 m to 2780 m above sea level. The region consists of limestone, quartzites, grit and earthy clay. The soil is sandy except ...

Eggshell patterning has been extensively studied in Drosophila melanogaster However, the cis-regulatory modules (CRMs), which control spatiotemporal expression of these patterns, are vastly unexplored. The FlyLight collection contains >7000 intergenic and intronic DNA fragments that, if containing CRMs, can drive the transcription factor GAL4. We cross-listed the 84 genes known to be expressed ...

Long-distance animal migrants often navigate in ways that imply an awareness of both latitude and longitude. Although several species are known to use magnetic cues as a surrogate for latitude, it is not known how any animal perceives longitude. Magnetic parameters appear to be unpromising as longitudinal markers because they typically vary more in a north-south rather than an east-west directi...

Precipitation is a function of many topographical land features as well as geographical locations. Spatial correlations between precipitation and topographical and geographical features can be used to improve estimation of precipitation distributions. In this study, kriging with external drift of topographical information was utilized for determining precipitation spatial distributions in Wyomi...
