Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

During football games neuromuscular fatigue occuring following eccentric movements such as sprint, jump and run that occur during games. To avoid injury, overtraining and performance decreases, it is important to know when players are recovered. The aim of the pilotstudy was to investigate physiological changes that occur during football matches and if they affect the recovery pattern after several games in professional football players. The method was divided into two sub-studies in which 12 professional footballers, in substudy 1 performed counter movement jump (CMJ) and drop jump (DJ) from 40 cm and fill out a recovery form for muscle soreness 36 hours before, 12-16 and 60-64 hours after 11 different competetive games. Blood samples were taken on the players in connection with one match to examine the activity of muscle enzyme creatine kinase (CK) and lactate dehydrogenase (LDH) of the players.

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.

EVA, Equine Viral Arteritis, was diagnosed for the first time in 1953 in USA. The disease gained international interest in 1984, when there were several outbreaks of abortion at Thoroughbred studs in USA. EAV, Equine Arteritis Virus, is an RNA virus in the Arteriviridae family. There is only one serotype of EAV but several strains and the strains have different virulence. EAV is transmitted in two different ways: by aerosols, or by venereal transmission.

The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.

This essay is intended for veterinary nurses and its purpose is to contribute to an increased knowledge about the ferret and there by a better nursing care at clinics. The essay discuss in briefness origin and earlier use of the ferret but also anatomy, physiology and reproduction. The senses of the ferret, as vision and hearing, are described in connection with behaviour. The part of the essay where nursing care is described bring up procedures as handling when collecting blood, medical techniques and how the clinic best should be suited for these animals. The main part of the essay is based on literature studies but it also contains a study visit at Blå Stjärnans animal hospital in Göteborg. 23.

Syftet med föreliggande studie var att undersöka sambandet mellan subglottalt tryck och ljudtrycksnivå, och undersöka inverkan av kön och tonhöjd. Röststyrkan är starkt beroende av subglottalt tryck och sambandet har analyserats i ett flertal studier, som alla visar på ett linjärt förhållande mellan logaritmen av subglottala trycket och ljudtrycksnivån (SPL). Schutte (1980) analyserade sambandet för 21 kvinnor och  24 män som producerade ett stort antal mätdata med olika SPL och tonhöjd. Tryck mättes med ballong i esofagus. Tanaka & Gould (1982) analyserade 4 kvinnor och 6 män på tre ljudnivåer på bekväm tonhöjd; svag, normal och stark ljudstyrka.

Lupus is the result of an investigative project in illustration. In my degree-work I have investigated the different guises of the wolf, which I have thenillustrated visually combined with some portions of text. The result, presentedin the form of a book of 36 pages, is narrated in a poetic and free style with meas a personal author. The images of the book tell the story of both the wolf of fleshand blood, as well as the wolf as a symbol. My work is produced with the hope thatby talking about the wolf in a way other than the standard, new ways of regarding apresently endangered but valuable animal, can arise..

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

The power consumption has grown rapidlyin the last decade. Fossil fuels and theneed for alternative energy sources aregreat. Ocean waves are a renewable andsustainable source of energy that hasbeen relatively untapped. At UppsalaUniversity research and development havebeen done for several years. Severaltypes of wave energy converters (WEC)have been created.

Människor förbrukar så mycket resurser att natureninte hinner med att återställa sig och där medförsvinner material allt mera. Det bästa vore om vimänniskor enbart använde oss av material som förbrukadesi samma takt som naturen kan återställa dei.Detta designprojekt fokuserar på Bois Durci, pådess tillverkning och användning. Materialet ärgjort av blod och sågspån och var tillgängligt på1800-1900-talet och försvann när bakeliten kom. Detsägs att materialet är bakelitens fader. I arbetet harjag samarbetat med ett företag från Torsåker i centralaSverige och arbetet utefter deras koncept somgrundar sig i att enbart använda sig av råvaror inomen femmilsradie.Arbetet har utgått från frågeställningen ?Kan BoisDurci tillverkas inom en femmilsradie och hur kanjag som designer ta mig an materialet?? Att användasig av en femmilsradie med utgångspunkten frånTorsåker var inte ett problem, det var enkelt att få tagi både blod och sågspån.

The bacterium Lactobacillus reuteri, which natural habitat is in the intestine of mammals and birds, uses glycerol as a substrate for production of the antimicrobial compound reuterin. Glycerol has been shown to decrease the number of Escherichia coli in human feces and it is believed to be due to in situ production of reuterin. E. coli belongs to the large family of Enterobacteriaceae, naturally occurring in the intestine, and pathogenic strains of E. coli have been shown to be one of several bacteria causing diarrhoea in calves.
