… och tätbebyggda städerna används gröna tak för att motverka den s k urban heat island effekten. Urbana värmeöar leder till högre temperaturer och luftföroreningar. Gröna tak kan hjälpa till med att kyla stadskärnan, förändra luftcirkulationen och rena luften från skadliga …
… to these cones there are a few cones that are able to spread the seed without heat. This makes the culture populations of lodgepole pine and their close environment is subjected to continuous exposure of viable seeds. The intention of this report is to investigate the potential …
… cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning. The results confirmed the differences in the saw particles …
… The result is discussed by considering a possible impact of the extensive heat-inactivation on the samples as well as geography, climate and trade pattern of the district of Gulu in Uganda.
… growth. The effect of the plant substrate was also tested after product heat treatment. The results showed that PYLOS effectively inhibits H. pylori in juice products containing different fruit mixtures. Juice E, with its unique fruit composition, turned out to be the most …
… fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam …
… burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials. There an object was located in the …
Fallstudie av värmelaster och innetemperaturer i fyra flerbostadshus
Intresset kring lågenergibyggnader blir allt större och så kallade passivhus, med god isolering, hög lufttäthet och värmeåtervinning, byggs i allt större utsträckning i Sverige och andra europeiska länder. Vissa frågetecken har dock uppkommit kring inomhusklimatet i husen och …
Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design …
… rapport jämför de båda economizersystemen flash tank cycle (FTC) och internal heat exchanger cycle (IHXC). Eftersom det har visat sig att vinsterna med economizerkopplingar är som störst då temperaturlyftet är stort är det mest intressant att jämföra dem i luft/vatten …
… demands on its insulating properties are growing. About 35 % of a building´s heat loss occurs through windows. This requires application of energy efficient windows in new constructions and redevelopments.Maintenance of windows is an inevitable detail and must occur at some …
… situations Germany can receive less electricity from Sweden. Electric district heating and maybe electric vehicles can in the future consume an oversupply of electricity. A large scale introduction of electric vehicles can increase the Swedish electricity consumption by 9 TWh …

Ett företag som tillverkar hydrauliska snabbkopplingar har genom regelbundna kvalitetsprover upptäckt att vissa låskulor till snabbkopplingarnas låsmekanism plötsligt fått en bristande kvalité och spricker vid belastning. Låskulorna är gjorda av rostfritt stål och har en viktig …
… the same power of 28 MW. The comparison shows the total energy recovery, of heat and electricity, for the combustible MSW in the stocker grate to 2.51 MWh, and for the 540 kg RDF incinerated in a fluidized bed to be 2,56 MWh. As long as the proportion of RDF processed from a ton …
