A lattice 9 is locally polar if each element is a join of points (atoms) and each interval L?$ = (y j x < y}, x a point, is a polar space (see Tits [6] or Buekenhout and Shult [4]). Recall that the rank of a polar space is the maximum projective dimension of an element; since this number is finite, 9 has a 1 and a 0. There is an obvious dimension function on 9, so lines and planes have the obvi...

Introduction: In this study, Antibacterial and antioxidant activities of the essential oil and methanolic extract of the endemic plant, Zataria multiflora Boiss. have been studied. Method: The antioxidant potential of the samples was evaluated using two separate methods of inhibition of free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ammonium thiocyanate systems. Antibacterial activity wa...

[1] United Kingdom Meteorological Office global analyses from 1991 to 2001 are used to create a global climatology of stratospheric polar vortices and anticyclones. New methodologies are developed that identify vortices in terms of evolving three-dimensional (3-D) air masses. A case study illustrates the performance of the identification schemes during February and March of 1999 when a merger o...

Using polarity, we give an outer polyhedral approximation for the epigraph of set functions. For a submodular function, prove that corresponding polar relaxation is exact; hence, it equivalent to Lovász extension. The approach provides alternative proof convex hull description function. Computational experiments show inequalities from approximations can be effective as cutting planes solving we...

This paper describes the development of an anthropomorphic visual sensor with retina-like structure to perform the polar mapping. The sensor consists of a dove prism for image rotation and a linear CCD sensor with 512 pixellline resolution, and holds approximately 45 Kbytes of image data. The retina-like sensor has variable resolution with increasing density towards the center of the visual fie...

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...
