Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst
A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.
Fastighetsmäklarbranschens rykte
Title: Real Estate Brokerage Industry's reputation - a study from a relationship marketing perspectiveLevel: Bachelor thesis in business administrationAuthors: Sanna Soininen & Sofia PulkkinenSupervisor: Jonas KågströmDate: 2013 ? AugustBackground: The background to this investigation was primarily another survey, conducted by Fastighetsbyrån, a Swedish real estate agency. According to the survey, only 5% of the Swedish population claims to have high confidence for realtors. The problem discussion revolves around statistics about how few real estate agents who are notified and receive sanctions each year. We believe that those numbers doesn't make sense when compared to how few people trust realtors, which is where our aim with the study comes from.Purpose: The aim of this study is to investigate the real estate brokerage industry's reputation by previous research in relationship marketing.Method: The study was conducted with a deductive and for the most part with a positivistic approach.
Att vara ung och leva med diagnosen ADHD. En kvalitativ intervjustudie med fokus på sociala och existentiella aspekter
Today many children and youths are allocated to ?The Swedish Authority of Child and Youth Psychiatry (BUP) for the sake of being investigated by means of a neuropsychiatric inquire and many of which are assigned the diagnosis ADHD. During recent years ?The Swedish National Board of Health and Welfare? has declared, in it?s annual account of the current psychiatric state of Swedish Children and Youths, that the healthcare provided for those with neuropsychiatric diagnoses ? such as Asperger syndrome and ADHD, has increased.ADHD is short for Attention deficit hyperactivity disorder, which implies neuropsychiatric impediments i.e. hyper activity, inadvertence and an inability to control impulses.The aim of the Study is to describe and analyze how youth, in the age range of sixteen to eighteen years of age, diagnosed with ADHD define themselves, their daily life, their social state, their next to kin relationships and, finally, their concept of their future.The Study is qualitative.
Lean för lantbruksföretaget : utvärdering av industriellt managementsystem i agrar kontext
The competitiveness and profitability of swedish farm enterprises is frequently discussed in agricultural media. Increased exposure to the surrounding world with greater competitive pressure and considerable price fluctuations in the agricultural markets demand new ways of acting to secure the agricultural sector?s long-term survival and profitability. Structural change and/or diversification leads to increased numbers of stake-holders around the farm enterprise and thereby also the expectations of the farmers ability to lead and coordinate resources. Lean is the name of a management model developed by Toyota, influenced by the lack of resources in Japan during the post WWII period.
Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :
Background
Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses.
The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.
Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms
This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos.
Chemical analyses and yeast counts were performed for fresh crop and silage.
Metodikstudie av trollingfisket i Vänern : Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning
There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.
Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri
Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.
Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Klimatsäkrare städer : klimatförändringar, stadsplanering och översvämningar
The numbers of natural disasters caused by extreme weather are increasing through out the world. A large majority of the research concerning the climate shows that this is a trend that can be expected to continue. At the same time the urbanisation is increasing more than ever and for the first time in history more than fifty percent of the population lives in a city. How we build these cities will have a crucial importance for our adaption to the new climate. In Sweden, our capacity for an adaption are high because of our economic situation as well as our rather well built society.
Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Cytologiska bedömningens påverkan på analysen av bronkoalveolärt lavage (BAL) samt förhållandet mellan andelen mastceller och proinflammatoriska cytokinmediatorer i BAL hos häst :
Inflammatory airway disease (IAD) is a respiratory disorder that most commonly affects young horses performing at a high level. The clinical signs are often mild but the disorder can cause a marked decrease in performance to a point where the horse has to be taken of training and competing. The aetiology underlying IAD is not yet fully understood. One current theory is that a type I-hypersensitivity reaction due to allergens in the environment is the cause in some horses. The most reliable diagnostic method is a bronchoalveolar lavage (BAL) since it reflects the inflammatory status in the most distal parts of the lungs, which are affected in IAD.
Marginaliserade aktörers inverkan på reglering och styrning av Internet : World Summit on the Information Society:s bidrag till nätets diskurs
Sedan nätets begynnelse har regleringen och styrningen av Internet präglats av en västcentrisk och teknomeritokratisk diskurs som i mångt och mycket har exkluderat en stor del av världen från att aktivt delta i informationssamhällets utformning. I denna ordning har den amerikanska staten haft en priviligierad ställning genom dess indirekta kontroll över de s.k. strategiska resurserna, dvs. IP-adresser och ?roten? i domännamnsystemet, via kontraktet mellan "Department of Commerce" och organisationen "Internet Corporation for Assigned Names and Numbers" (ICANN).
