Observing averted eye gaze results in the automatic allocation of attention to the gazed-at location. The role of the orientation of the face that produces the gaze cue was investigated. The eyes in the face could look left or right in a head-centred frame, but the face itself could be oriented 90 degrees clockwise or anticlockwise such that the eyes were gazing up or down. Significant cueing e...
z-If the Z0 boson is made of colored subconstituents it can be produced in pp (and pp) collisions through the subprocess gluon + gluon-) Z " + gluon. Rate is estimated from Z "-7 mixing parameter and found comparable to that of Drell-Yan process.-Events with a large PT 2' and a large PT balancing gluon should be observed at pp collider. The possibility that the weak W* and 2' bosons together wi...
I show that a cosmological constant of roughly the observed magnitude in the present universe is a consequence of general relativity and quantum field theory in curved spacetime, and was first predicted by Parker and Toms in 1985. This prediction follows from the “new partially summed form” of the propagator in curved spacetime. The effect is based on the contribution of massive particles to th...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Backgrounds Many wild-caught reptiles harbor some kind of parasites. Captivity with negative effect of poor sanitary and husbandry management may lead to clinical disease. The increasing trend in keeping non-native reptile species in the last decade emerged a need for the specification of reptile parasites and their hosts. Objectives The study aims to gain data on intestinal parasites of repti...
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
