Agriculture is one of the major sources of greenhouse gas (GHG) emissions accounting for approximately 14 percent of total GHG emissions. However, unlike other sectors such as transport or energy, agriculture is potentially a significant carbon 'sink'. Moreover, because...

Climate change presents significant threats to sustainable poverty reduction in Tajikistan. The primary impacts on rural livelihoods are expected to stem from reduced water quantity and quality (affecting agriculture), and increased frequency and severity of disasters. ...

In many Heating, Ventilation and Air-Conditioning (HVAC) applications, heat recovery (HR) devices are installed, aiming at reducing energy consumption. Especially in buildings requiring a high percentage of outside air for ventilation, there is a high potential for HR f...

Tämän kandidaatintyön tavoitteena on tutkia kertakäyttöisten kartonkikuppien viimeaikaista kehitystä muotoilun, materiaalien ja loppukäytön osalta. Työssä esitetään myös kartonkikuppien rakenne ja valmistusprosessi. Työ on kirjallisuustutkimus ja tiedonhakuun on käytett...

A significant improvement in economic and environmental performance of production thermal energy can be achieved by using heat pumps. Whereas ground waters, an air and a ground itself are well-known and explored heat sources, the heat that residents return to the ground...

The LTSER Zone Atelier Hwange (ZAHWG) belongs to LTER-France network and is located in western Zimbabwe, in Sub-Saharan Africa, and is centered around Hwange National Park. The ecosystem is dominated by dystrophic savannas (mostly wooded savannas and dry woodlands) with...

Drying kinetics of Pistachio kernels (PKs) with initial moisture content of 32.4% (w.b) was investigated as a function of drying conditions in a fixed bed drying system. The drying experiments were carried out at different temperatures of drying air (40, 60 and 80°...

The aim of this paper is to study a conservative wave equation coupled to a diffusion equation : this coupled system naturally arises in musical acoustics when viscous and thermal effects at the wall of the duct of a wind instrument are taken into account. The resulting...
