according to general circulation model (gcm), zonal thermal belts are 1- inter-tropical convergence zones (itcz) around eqator; 2- sub tropical high (sth) belt around 30 degree latitude; 3- sub polar low (spl) belt around high latitudes. the belt of inter-tropical convergence zone (itcz) displaces in meridional path, about 5° over the oceans and up to 40° over continents, during the seasons of ...

The current study examined the effect of empathy on friendship quality in the context of dyadic same-sex friendships, and how such an effect might be mediated by interpersonal competence. A special version of the actor-partner interdependence model (APIM) was used to examine this hypothesis in 146 same-sex friend dyads in 10th grade. Results showed that empathy was positively related to intimac...

The shape of allele-frequency clines maintained by migration-selection balance depends not only on the properties of migration and selection, but also on the dominance relations among alleles and on linkage to other loci under selection. We investigate a two-locus model in which two diallelic, recombining loci are subject to selection caused by an abrupt environmental change. The habitat is one...

T h e Lysenko case has become a symbol of the ideological dictate in science and its damaging consequences. It is often explained that in the years following World War 11, the Stalinist leadership launched an ideological and nationalistic campaign aimed at the creation of a Marxist-Leninist and/or distinctively Russian, non-Western science. Concepts and theories which were found idealistic or b...

Pulsed nuclear magnetic resonance techniques with transverse radiofrequency pulses are used to determine the spin-lattice and spin-spin relaxation times of glycerol and Fe solutions of varying concentrations. The nuclear magnetic moments of flourine and hydrogen are found to be μH+ = (1.408± .008)× 10−26 J/T and μF− = (1.324± .007)× 10−26 J/T, respectively. A negative linear relation in log-log...

HU93030-007 LCF (65o01.390N and 30o14.810W) is a 4.5 m long, giant (11 cm diameter) piston core from 1800 m water depth on the continental slope, south of the Denmark Strait sill. The core sampled acoustically stratified sediments at a site below the Kangerlussuaq Trough. Nine AMS C dates on planktic foraminifera indicate that the core spans 3⁄414 to 28 C ka. The sediments consists of two princ...
