in order to study of efficiency total dual purpose herbicide and mixed granestar and acsiyal herbicides, and response of wheat at growth various stages to the aforementioned herbicides, an experiment with randomized complete block design with three replications were conducted during 2008-2009 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments in...

‎we study dual integral equations which appear in formulation of the‎ ‎potential distribution of an electrified plate with mixed boundary‎ ‎conditions‎. ‎these equations will be converted to a system of‎ ‎singular integral equations with cauchy type kernels‎. ‎using‎ ‎chebyshev polynomials‎, ‎we propose a method to approximate the‎ ‎solution of cauchy type singular integral equation which will ...

We give a combinatorial interpretation for the mixed volumes of two adjacent slices from the unit cube in terms of a refinement of the Eulerian numbers. 1998 Academic Press Let C d denote the d-dimensional unit cube, that is, C d =[x # R d : 0x i 1]. All the volumes and mixed volumes which appear in this note will be normalized so that the volume of C d is given by V(C d)=d!. We consider slices...

Below is a method for relating a mixed volume computation for polytopes sharing many facet directions to a symmetric random walk. The example of permutahedra and particularly hypersimplices is expanded upon.

This paper gives various (positive and negative) results on the complexity of the problem of computing and approximating mixed volumes of polytopes and more general convex bodies in arbitrary dimension. On the negative side, we present several #P-hardness results that focus on the difference of computing mixed volumes versus computing the volume of polytopes. We show that computing the volume o...

OBJECTIVES Pericardial fat as a visceral fat depot may be involved in the pathogenesis of coronary atherosclerosis. To gain evidence for that concept we sought to investigate the relation of pericardial fat volumes to risk factors, serum adiponectin levels, inflammatory biomarkers, and the quantity and morphology of coronary atherosclerosis. METHODS AND RESULTS Using Dual source CT angiograph...
