A quantum field theory in its algebraic description may admit many irregular states. So far, selection criteria to distinguish physically reasonable states have been restricted to free fields (Hadamard condition) or to flat spacetimes (e.g., Buchholz-Wichmann nuclearity). We propose instead to use a modular `p-condition, which is an extension of a strengthened modular nuclearity condition to ge...
Walking is the most natural way of moving within a virtual environment (VE). Mapping the user’s movement one-to-one to the real world clearly has the drawback that the limited range of the tracking sensors and a rather small working space in the real word restrict the users’ interaction. In this paper we introduce concepts for virtual locomotion interfaces that support exploration of large-scal...
Circulating concentration of progesterone (P4) is determined by a balance between P4 production, primarily by corpus luteum (CL), and P4 metabolism, primarily by liver. The volume of large luteal cells in the CL is a primary factor regulating P4 production. Rate of P4 metabolism is generally determined by liver blood flow and can be of critical importance in determining circulating P4 concentra...
Atmospheric dispersion produces spectral elongation in images formed by land-based astronomical telescopes, and this increases as the telescope points away from zenith. Dispersion Correctors (ADCs) produce compensating that can be adjusted to best cancel out atmospheric effect. These correctors are generally of two basic types: Rotating (R-ADCs), Linear (L-ADCs). Lately, a third type, “Compensa...
Abstract. Nitryl chloride (ClNO2) is an important chlorine reservoir in the atmosphere that affects oxidation of volatile organic compounds (VOCs) and production ROx radicals ozone (O3). This study presents measurements ClNO2 related at urban, polluted rural, lower tropospheric (mountaintop) sites winter 2017–2018 over North China Plain (NCP). The nocturnal concentrations were urban rural but h...
Previous studies that have evaluated the Na(+)-H+ antiporter in cells from hypertensive subjects were generally performed under conditions in which HCO3-CO2, the physiological buffer system, was absent from the assay media. The objective of this study was to evaluate the activity of the Na(+)-H+ antiporter and that of the Na(+)-dependent and Na(+)-independent Cl(-)-HCO3- exchangers in cells ass...
In ruminants, there are specific times during the estrous cycle or pregnancy when the corpus luteum (CL) may undergo regression. This review has attempted to summarize the physiological and cellular mechanisms involved in CL regression or maintenance during four distinct periods. The first period is near day 7 when animals that are ovulating after a period of low circulating progesterone (P4), ...
Most local people in the agricultural areas of Sistan and Baluchestan Province (Iran), generally consume shallow groundwater from farm wells. This study aimed to assess the water quality and health risk potentially of As, Pb, Cr and Ni for drinking purposes in Zarabad aquifer. Also the geochemical processes controlling chemistry of Zarabad aquifer were studied. Piper diagram shows two major hyd...
analytical results of 11 groundwater samples are used to evaluate the quality of groundwater in the hastijan area, (central province –iran). the main indices of water, ions physicochemical characteristics and the important heavy metals concentration studied. to estimate of water quality, piper, ghibbs, schoeller and wilcox diagrams, sodium absorption ratio, color-alkalinity and saturation index...
