Effect on Diesel Engine Performance Parameters Using Hydrogen and Oxygen Produced on Demand

open access: yesEnergies, 2022
Hydrogen is seen as a future energy carrier since its chemical compounds make up a large part of the Earth’s surface. This study sought to analyze the impact related to the inclusion of hydrogen and oxygen gases produced on demand by an alkaline ...

Comparison of climate and production in closed, semi-closed and open greenhouses [PDF]

open access: yes, 2011
A (semi-)closed greenhouse is a novel greenhouse with an active cooling system and temporary heat storage in an aquifer. Air is cooled, heated and dehumidified by air treatment units. Climate in (semi-)closed greenhouses differs from that of conventional

Nitrous oxide and methane fluxes in south Brazilian gleysol as affected by nitrogen fertilizers Fluxos de óxido nitroso e de metano em gleissolo influenciados pela aplicação de fertilizantes nitrogenados no sul do Brasil

open access: yesRevista Brasileira de Ciência do Solo, 2010
Nitrogen fertilizers increase the nitrous oxide (N2O) emission and can reduce the methane (CH4) oxidation from agricultural soils. However, the magnitude of this effect is unknown in Southern Brazilian edaphoclimatic conditions, as well as the potential ...

The combined effects of cover design parameters on tomato production of a passive greenhouse [PDF]

open access: yes, 2008
The objective of this paper is to demonstrate the need of a multiple design parameter approach to greenhouse design. To illustrate this need, we determined the combined effects of cover design parameters on tomato production of a passive greenhouse, that

Model Analysis of Solar Thermal System with the Effect of Dust Deposition on the Collectors

open access: yesEnergies, 2018
In this study, a TraNsient SYStems (TRNSYS) simulation model for solar thermal systems is developed to assess the potential of solar energy utilization in cold climate zones, such as Ulaanbaatar (Mongolia), which is one of the five cities with the worst ...
