The efficient use of energy, or energy efficiency, has been widely recognized as an ample and cost-efficient means to save energy and to reduce greenhouse gas emissions. Up to one third of the worldwide energy demand in 2050 can be saved by energy effici

The highest energy efficiency coefficient and the lowest energy costs for growing of 1 ton of fodder units were obtained on the sowings of common sainfoin of Ametyst Donetsky variety. 展开 DOI: 10.31395/2415-8240-2020-97-1-91-102
The definitions of some of these scales, especially the more obscure ones, fall far short of modern standards for precision and reproducibility — so any results among them should be taken with a colossal grain of salt!Gramercies:The units Gas Mark, Stufe, and Thermostat appear on some ...
These units are highly energy efficient. Some of the models integrated with triple inverter plus technology promise up to 65% energy savings. The in-built air purifiers eliminate all kinds of pollutants and ensure you breathe clean air.
(note that they do not necessarily appear in increasing order from left to right). The units of the independent variables shown are exajoules for primary and secondary energy, and million tonnes of CO2for emissions and carbon sequestration (negative AFOLU emissions represent CO2removal). Cumulative...
Oils are important sources of energy in pig diets. The combination of oils with different degree of saturation contributes to improve the utilization efficiency of the mixed oils and may reduce the cost of oil supplemented. An experiment was conducted to evaluate the effects of oils with different...
Although the relationship between species richness and available energy is well established for a range of spatial scales, exploration of the plausible underlying explanations for this relationship is less common. Speciation, extinction, dispersal and en
We report the synthesis, characterization, and optical and electrochemical of properties of two novel molecules DRT3-BDT (1) and DTT3-BDT (2), comprising the same BDT central core (donor) and different end capped acceptor units, i.e. rhodanine with ethyl hexyl and thiazolidione with ethylhex...
higher optical efficiencies and better thermal performance compared to the evacuated and non-evacuated single collector units due to better optics of the tubes in relation to energy collection and better collimation effect from the lamps of the solar simulator as a result of larger aperture areas [...
