The building sector accounts for 40% of the total energy consumed in Europe at annual basis, together with relevant Greenhouse Gas (GHG) emissions. In order to mitigate these impacts, concept and establishment Nearly Zero Energy Buildings (NZEBs) is under continuous intensive research. fact, as used buildings’ operation becomes more efficient, impacts resulting from embodied become importance. ...

one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of  superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...

the aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. thermal efficiency is defined as a function of unknown variables (fluid pressure and vapour ...

δCO2 measured in Antarctic ice cores provides constraints on oceanic and terrestrial carbon cycle processes linked with millennial-scale changes in atmospheric CO2. However, the interpretation of δCO2 is not straightforward. Using carbon isotope-enabled versions of the LOVECLIM and Bern3D models, we perform a set of sensitivity experiments in which the formation rates of North Atlantic Deep Wat...

objective: gastric cancer is a major health issue worldwide. using a therapeutic approach, with minor side-effects, is very essential for the treatment of the gastric cancer. shiraia bambusicola is a parasitic fungus which is widely used in china for curing several diseases with little side-effects. however, the mechanisms are not well understood yet. the aim of this study was to further unders...

Research in the area of sustainable urban infrastructure reflects the need to design and manage engineering systems in light of environmental, economic, social and technical considerations. In the water sector, the main challenge for the engineer is the development of practical tools for measuring and enhancing the sustainability of urban water infrastructure over its life cycle. The present st...

Climate changes, failure to complete the natural cycle of water in the city due to unsustainableconstruction of the urban environments and increase of impervious surfaces, lack of nutrition of undergroundaquifer in the cities, unsustainable management of stormwater and the floods due to them in the periods of rainfallcaused to provide an approach that is called water sensitive urban design. Thi...

High quality water is less available for agriculture and thus farmers often use saline water, that affects crop growth and yield. Snap bean (Phaseolus vulgaris) is sensitive to soil and water salinity, and also to heat stress. The aim of this research is to evaluate if a postponed transplant (high temperature stress) of snap bean can influence growth and yield under saline conditions. Snap bean...

The present paper describes the energy and exergy analysis of a reheat regenerative vapor power cycle. The plant consists of one boiler feed pump, one supercritical boiler, two steam turbines with a reheater in between, two feed water heaters (one open and one closed) and a condenser. The energy and exergy balance study has been carried-out for each component of the plant. Energy efficiency, ex...
