The objective of this study is to evaluate the energy efficiency of residential buildings by using natural energy and optimizing the choice of materials for heat and cold saving with the Ecotect simulation software. According to analysis and simulation was found that the optimum material of main building components in a mild climate zone of Rasht city is the Brick Conc block Plaster for wall wi...

background: image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. objectives: this study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in iran. methods: in this study, the most important medical datab...

The microand macrophysical properties of clouds play a crucial role in Earth’s radiation budget. The NASA Clouds and Earth’s Radiant Energy System (CERES) is providing simultaneous measurements of the radiation and cloud fields on a global basis to improve the understanding and modeling of the interaction between clouds and radiation at the top of the atmosphere, at the surface, and within the ...

The mean values of the radiation balance of the earth's surface, the atmosphere, and the earth-atmosphere system as a whole are well established. However, this does not apply to the parameters of local areas of the earth's surface and the atmosphere above them. The radiation balance of such local objects experiences considerable variations depending on the spatiotemporal distribution of cloud a...

This study assesses the ability of the recent chemistry version (v3.3) of the Weather Research and Forecasting (WRF-Chem) model to simulate boundary layer structure, aerosols, stratocumulus clouds, and energy fluxes over the Southeast Pacific Ocean. Measurements from the VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) and satellite retrievals (i.e., products from the MO...

background: the fatal effect of ionizing radiation on cells depends on linear energy transfer (let) level. the distribution of ionizing radiation is sparse and homogeneous for low let radiations such as x or γ, but it is dense and concentrated for high let radiation such as heavy-ions radiation. material and methods: chinese hamster ovary cells (cho-k1) were exposed to 4 gy fe-ion 2000 kev/m. ...

In the present study, Morrison double-moment cloud microphysics scheme including mass and droplet number concentration of water ice clouds is implemented into Chinese mesoscale version Global/Regional Assimilation Prediction System (GRAPES_Meso). Sensitivity experiments different condensation nuclei (CCN) values are conducted to study impacts CCN on microphysical processes radiation in East Chi...

A thin cirrus cloud thermal infrared radiative transfer model has been developed for application to cloudy satellite data assimilation. This radiation model was constructed by combining the Optical Path Transmittance (OPTRAN) model, developed for the speedy calculation of transmittances in clear atmospheres, and a thin cirrus cloud parameterization using a number of observed ice crystal size an...

Forecast systems provide decision support for end-users ranging from the solar energy industry to municipalities concerned with road safety. Pavement temperature is an important variable when considering vehicle response to various weather conditions. A complex, yet direct relationship exists between tire and pavement temperatures. Literature has shown that as tire temperature increases, fricti...

In this study, an analysis of the monthly mean values of the fraction of the sky covered by clouds (C) of all types and the duration of bright sunshine hours (S) and global solar radiation on the horizontal surface (H) was carried out to establish relationship for solar radiation estimation for Bangladesh. The relationship between C and (1 − S/S0), where S0 is the maximum possible hours of suns...
