… in what month they usually appear. Parameters such as sea-and air temperature, wind direction, directional shear, ice cover and snow amounts are used to define days with convective snowbands. The study shows that convective snowbands occurred during 73 days during the years 1980 …
… the water rapidly caused them to become highly stratified, thus preventing the wind from releasing deeper stored carbon. Presumably, this holds true for other similar boreal lakes as well, which suggests that attention ” in such ecosystems ” also needs to be brought to other …
… occur but also a noticeable effect on the scale of the injury. Snow and wind seems to cause an increased risk of falling as well as an increase of the injury scale.
En känsla av tillhörighet
… breath we take we inhale 1000 of dust particles and without knowing it the wind could have brought invisible camelhair from the Sahara desert that you just know have inhaled into your system. The most fascinating is that under your bed you can find traces of particles that have …
… to be able to handle a larger share of intermittent electricity from solar, wind or hydropower that can automatically interact with thermal energy from biomass and waste in a flexible, efficient and economical manner. The project group therefore advice HEM to urgently take steps …
… solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction …
En kartläggning och analys av de balansansvarigas arbetsgång
A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and …
<em>Förslag på design av statorstomme för användning i vertikalaxlade vindkraftverk</em>
… design of a support frame for a synchronousgenerator used in a vertical axis wind power plant. In this system the generator isplaced on ground level. The thesis also considers the design of housing for thesupport frame and generator. The concept presented in this report is based …
Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla
… heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available. Theoretical …
… that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads. The elements are made of lightweight beams with flanges of structural timber and beam webs made …
Människans näringar och kulturer har orsakat landskapsförändringar som på många håll i världen lett till flera ekologiska konsekvenser som erosion liksom övergödning av vattendrag och hav. Skogsbruk såväl som jordbruk har därutöver resulterat i stora utarmningar av den …
… operation. Due to the increasing amount of intermittent energysources, such as wind and solar power, the energy system will require that theplants that run as base load today will be able to rapidly respond to changes in load.The present work investigates the operation of a coal …
Hur företagens investeringsbedömning påverkas av deras syn på risk och osäkerhetsfaktorer
Nyckeln till ett framgångsrikt och värdefullt företag är att göra bra investeringar eftersom det är investeringarna som skapar den avkastning som dess ägare får som ersättning (Froot, et al., 1994). Om företaget strävar efter att göra värdemaximerande investeringar måste de …
En studie om rumsliga landskapspreferenser och vindkraftens påverkan på de svenska fjällen
De svenska fjällen skyddas i dagsläget av miljömålet Storslagen fjällmiljö, ett mål som ämnar bevara fjällens ursprunglighet och därmed skydda dem mot ingrepp. Den svenska regeringen har även inrättat 13 områden klassade som obruten fjällmiljö, områden vars natur- och …
… The reason was that the bridge weighed too little to withstand the strong wind forces. The stadium Ullevi in Gothenburg had to be strengthened due to the fact that a jumping crowd during a concert caused resonance oscillations which endangered parts of the construction. After …
