Kan borrhålskyla ersätta en kylmaskin?
… system. Växthuspotentialen beräknas i alla dessa steg som totala koldioxidekvivalenter. Ett sätt att bedöma den energibesparing som har gjorts är med en EROI-analys. EROI beräknas som sparad energi dividerat med investerad energi och är ett dimensionslöst tal som ger en …
… Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers. Two external high-strength layers and a middle layer of …
… of our planet. They use photosynthesis to produce ATP and gain biomass from carbon dioxide. The cyanobacteria Nostoc punctiforme is a filamentous bacterium that consists of two different types of cells, vegetative cells and heterocysts. The type of cell it differentiates into …
… in land use, use of pesticides and fertilizers as well as absorption of carbon dioxide differ. Pulp and fibre production should be integrated to reduce energy consumption and the amount of chemicals used. The energy can also be recycled to a greater extent.Eco-labels from …
koldioxid eller alternativa gasmixturer?
I Sverige är det lagstadgat att djur skall vara bedövade innan de slaktas. Att upprätthålla en god djurvälfärd i slaktsituationen är inte enbart en grundpelare i vår svenska djurskyddslag, utan även en ständigt aktuell fråga som engagerar både livsmedelsproducenter likväl som …
… foal rather than the adult horse. Foals are also more sensitive to changes in carbon-dioxide and arterial oxygen pressure than adult horses because of their undeveloped sympathetic nervous system. Another difference of great importance that separates adults and neonates is the …
… perfusion pressure, muscle perfusion, muscle metabolism, lactate, end-tidal carbon dioxide, stroke volume (SV), system vascular resistance (SVR) and heart rate. Different monitoring devices and techniques comprises: (direct) blood pressure, electrocardiography, capnography …
… fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed …
Ökad växthuseffekt har länge varit i fokus för dess inverkan på framtida klimat. Det är i huvudsak mänskliga utsläpp som är orsaken till ökade mängder växthusgaser i atmosfären och stora ansträngningar görs för att utsläppen på sikt ska minska. I klimatmodeller beskrivs …
… reduction of 188 MWh per year, which corresponds to 70 000 SEK or 118 tons of carbon dioxide emission. This represents approximately 11 % of the total target in energy loss reduction and can be done immediately, with no need for investments. For long-term actions a possible 424 …
… positive effect of the systems with absorption heat pumps is the decrease in carbon dioxide emissions from the heat production. The result of the Master thesis shows that both economic advantages and increased resource efficiency can be achieved through integration of a borehole …
