The fossil fuels consumption is rapidly growing due to increased water and electricity demands. An interconnected water-energy nexus is generally composed of thermal power plants, combined potable water and power (CWP) generation units, and desalination only processes. Hence, participation of hydro power plants in electricity generation facilities not only reduces the total fuel consumption of ...

Spatially intimate symbioses, such as those between scleractinian corals and unicellular algae belonging to the genus Symbiodinium, can potentially adapt to changes in the environment by altering the taxonomic composition of their endosymbiont communities. We quantified the spatial relationship between the cumulative frequency of thermal stress anomalies (TSAs) and the taxonomic composition of ...

Combined cooling, heat, and power (CCHP) units can be integrated with conventional separate cooling, heat, and power production units to meet demands. The goal of this study is to develop and examine a hybrid GA-heuristic optimization algorithm for solving the unit commitment problem for integrated CCHP-thermal-heat only system with considerations for electricity boiler. When environmental emis...

Abstract The paper deals with strategies for numerical compensation of thermo-mechanical deformation machine tool spindles and the TCP, respectively. Methods digital modelling simulating temperatures thermo-elastic are presented. This is done by considering geometry, material data, drive signals temperature values. topic compensating effects in spindle units an important manufacturing. Analytic...

PURPOSE An investigation of the thermal effect and the potential for injury at the lung surface following thermal vapour ablation (InterVapor), an energy-based method of achieving endoscopic lung volume reduction. METHODS Heated water vapour was delivered to fifteen ex vivo human lungs using standard clinical procedure, and the thermal effect at the visceral pleura was monitored with an infra...

The manifestations of climate change are increasing with the days: sudden rains and floods, lakes that evaporate, rivers experience unprecedentedly low water levels, successive droughts such as Tigris, Euphrates, Rhine, Lape rivers. At same time, energy consumption is increasing, there no way to stop warming Earth's atmosphere despite many conferences growing interest in environmental problems....

autumn sugar beet sowing has priority to its spring sowing in terms of economic productivity and water use efficiency. in khorasan razavi and khorasan-e-jonobi provinces, sugar beet is only sown in spring. therefore, it is necessary to evaluate the feasibility of autumn sugar beet sowing in these regions. using geographical information systems is the best and inexpensive way to identify suitabl...

the quality of environmental impact assessment (eia) findings, as a decision support system, has always been a function of the extent of its boundaries. meanwhile, boundaries of a study area can be delineated physically or non-physically according to the eia working units or methodologies. six case studies have been conducted to consider the study areas of variety of eias namely, visual, cumula...

For the purpose to facilitate development of high-speed Spindle Units (SUs) running on rolling bearings, we have developed a beam element model, algorithms, and software for computer analysis of thermal characteristics of SUs. The thermal model incorporates a model of heat generation in rolling bearings, a model of heat transfer from bearings, and models for estimation of temperature and temper...
