Nitric oxide is a pollutant linked to the production of smog and acid rain in the environment. Due to the increase in production of nitric oxide, scientists have attempted to increase methods to detect the pollutant at low and high concentrations. Scientists have investigated gas sensors because of their low cost, sensitivity to gases at low concentrations, and fast response time. WO3 gas sensi...
Introduction: In radiotherapy treatment planning system (TPS), basic input is the data from computed tomography (CT) scan, which takes into account the effect of inhomogeneities in dose calculations. Measurement of CT numbers may be affected by scanner-specific parameters. Therefore, it is important to verify the effect of different CT scanning protocols on Hounsfield unit (HU) and its impact o...
Three-dimensional localization spectroscopy of individual nuclear spins with sub-Angstrom resolution
a novel approach to determine optimal sampling locations under parameter uncertainty in a water distribution system (wds) for the purpose of its hydraulic model calibration is presented. the problem is formulated as a multi-objective optimisation problem under calibration parameter uncertainty. the objectives are to maximise the calibrated model accuracy and to minimise the number of sampling d...
in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...
SDO/AIA images the full solar disk in several EUV bands that are each sensitive to coronal plasma emissions of one or more specific temperatures. We observe when isolated active regions (ARs) on disk, full-disk some channels show outskirts AR as a dark moat surrounding AR. Here we present seven examples, selected from time periods there was only single disk. Visually, be most prominent AIA 171 ...
