Denna rapport innehåller en utredning av effektflöden på Uddevalla Energi Elnät AB:s mottagningsstationer och optimering av driftläggning för dess effektkondensatorbatterier och transformatorer.Uddevalla Energi Elnät AB har sedan 30 år haft effektkondensatorbatterier inkopplade nästan hela året och dessa behöver av åldersskäl snart bytas ut. Uddevalla Energi Elnät AB har därför behov av nya rutiner för driftläggning av effektkondensatorbatterier efter det att Svenska Kraftnät och Vattenfall AB har infört nya regler för de reaktiva effektflödena i elnätet.I utredningen om effektkondensatorbatterier har det gjorts en investeringskalkyl med tre alternativ för inköp. Alternativ 1 med central faskompensering på mottagningsstation, alternativ 2 med faskompensering på mottagningsstation kompletterat med faskompensering på abonnentstationer och alternativ 3 med lokal faskompensering på abonnentstationer.  Det framkom i utredningen att alternativ 2: Central faskompensering kompletterat med faskompensering på abonnentstationer är mest lämplig att genomföra.  Det har tidigare konstaterats att det under delar av året har varit låg belastning på några av mottagningsstationernas transformatorer. Det har aldrig utretts om det är lönsamt att stänga av den ena transformatorn under hela eller delar av året.I utredningen om driftläggning av transformatorerna på mottagningsstationerna har det beaktats tre alternativ. Ett alternativ innebär att en transformator körs i tomgång utan last och ett alternativ med en helt avstängd transformator.

Hemmasittare is a new term for children and youths with a history of long term truancy. As the term indicates these youths spend most of their time in their homes. This often results in them being socially alienated and the loss of their earlier social network. The consequences of hemmasittande and social alienation are many and include not only a deficient social network but also psychological and physical problems. Research has shown that many of these problems follow on through into adult life.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

The purpose of this study was to evaluate meals and eating in one day for at least ten truck or lorry drivers. Another aim was to investigate the attitudes by the drivers to food and meals and their expectations on the meals. This is a qualitative study conducted in ten interviews, seven of which were over the phone. The interviews were semi-structured and took about twenty minutes for each driver. Data relating to the food choices for one day were collected and questions asked about their attitudes to food and meals were collected simultaneously.

Nipahvirus is most likely spread from bats to other species and causes lethal encephalitis in humans and respiratory illness in pigs. Different species are affected with varying severity but it seems to have an unprecedented zoonotic capacity and the humans affected either die or receive permanent brain damage. Full recovery is possible but very uncommon. Pigs that live and are bread in the areas that these bats frequent are constantly in danger of contracting pneumonias and meningitis and they can spread the virus further on to the people who work with the pigs and process their carcasses. These workers could then infect other humans in their immediate surroundings, their families for instance.

På senare år har intresset för trollsländor ökat. I jämförelse med andra stora och lättstuderade insekter finns dock relativt få vetenskapliga och systematiska studier. Denna studie syftar till att undersöka hur habitatet påverkar trollsländearternas förekomstmönster och detekterbarheten hos olika arters larver samt inventeringsmetodens effektivitet. Med detekterbarhet menas sannolikheten att arten upptäckts givet att den finns på lokalen. Både larver och adulta trollsländor inventerades i 14 dammar i Frihult, Sjöbo kommun i Skåne under juni-augusti 2009.

Urbanisering och förtätning leder till att habitat fragmenteras och att grönytor minskar, vilket gör det svårt att värna om den biologiska mångfalden. Ett exempel på grön infrastruktur är gröna tak som blir ett självklart val för att sammanfoga grönytor i en stad. Förutom flera privat- och samhällsekonomiska vinster, kan gröna tak bidra till att öka den biologiska mångfalden. Vegeterade tak består vanligen av prefabricerade mattor som har ett tunt substratdjup med en vegetation som främst består av Sedum album och mossa. För den biologiska mångfalden har dessa mattor ett lågt värde till skillnad från biodiversitetstak som hyser en mer varierad flora och fauna.

Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in modern buildings. In modern contemporary construction, large glass panels are often the ideal because of increased light inflow and for architectural purposes. However, this can generate several negative effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that window shutters could have accommodated historically. This thesis identifies a lack of knowledge about interior window shutters in the Swedish building stock.

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

Due to progresses constantly being made in veterinary medicine combined with increasing knowledge in pet owners, the dogs of today gets older than before. The population of geriatric dogs is there for constantly growing, which makes them an important group of patients on small animal clinics and hospitals. As dogs age, so do their interior organs. Geriatric dogs are prone to several diseases and in this text the author has decided to focus on three of the most common: Cognitive Dysfunction Syndrome (CDS), cancer and osteoarthritis (AO). All of these illnesses are incurable in dogs, but it is important to remember that they are still treatable.

Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.
