Vattenkvalitet och risker vid ändrat intag för vattenförsörjning i Västerås

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Utveckling och tillämpning av en GIS-baserad hydrologisk modell

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

Upprepad administrering av trimetoprim/sulfadiazin till neonatala föl : plasmaproteinbindning och effekt på serumbilirubinkoncentrationen

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.

MUSKULÄR STYRKA VID MULTIPLA REPETITIONER: : SKILLNADER VID STYRKETEST I BÄNKPRESS OCH LIGGANDE BÄNKRODD MED SKIVSTÄNGER AV OLIKA DIAMETEROMFÅNG

Introduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual?s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different  bar sizes.Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar.

Syftet med denna undersökning var att utforska den lärandes perspektiv genom att lära oss spela ett nytt instrument. Genom att försätta oss i en sådan situation och sedan granska våra egna läroprocesser hoppades vi kunna bemöta våra framtida elever med djupare förståelse. Vi ville på detta sätt försöka synliggöra faktorer som påverkar vårt lärande och bilda oss en uppfattning om hur vi påverkas av dessa.Undersökningen utfördes med oss själva som studieobjekt där vi under hela processen noggrant förde dagbok över våra upplevelser, både skriftligt och med ljudande inspelningar. Inspelningarna bifogas som en bidragande gestaltning till det avsnitt som kallas Processen. I Processen förekommer diskuterande tolkningar som fullföljs i Epilogen.Vår studie visar att det är svårt att till fullo sätta sig in i en nybörjares roll.

Är variation i STFI-tjocklek ett bra mått på kartongs bulighet? : Are variation in STFI-thickness a good measure of uneven surface, bumpiness, on cardboard?

This degree project aim to evaluate if variations of the STFI thickness can be used to assess bumpiness on cardboard. During the project cardboard samples were measured using Bendtsen, PPS, a L&W formation tester, OptiTopo, Ambertec formation, the STFI thickness tester and a visual comparison. The different methods were then compared to see if there is any correlations between them. The results showed that the visual comparison and OptiTopo correlates. The STFI thickness tester shows however no correlation with the OptiTopo and visual comparison, thus aren't suitable measuring bumpiness..

Regional Integration i Afrika - En analys av COMESA:s handelseffekter

This study examines regional integration in Africa with a focus on the Common Market for Eastern and Southern Africa, COMESA. COMESA, with roots that go back to the beginning of the 1980?s, is one of the largest and most diverse areas for regional integration in Africa and has currently 19 member countries. The goal of the COMESA co-operation is to become a fully integrated area by the year 2025 that will merge into the African Union (AU). AU will then, in turn, create a fully integrated African continent in a not too far away future.

Interna processer : Modell för ett effektivt returstålsflöde

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

Swedish farmers - are they entrepreneurs? : and is there a support function for LRF to fulfil?

The EU market is being deregulated, which sees Swedish farmers that have traditionally been governed by different support systems being forced to adapt to a free market system and having to deal with the concept of supply and demand. The farming sector has during the past several years experienced harder conditions and the deregulation of the market has directly affected farmers. The need for entrepreneurs and that way of thinking has been identified (McElwee, 2006). Swedish farmers are neither familiar with a free market or being required to think in an entrepreneurial manner, does this therefore implicate that Swedish farmers are not entrepreneurs?LRF is a national farmers? organization in Sweden and functions as a support for Swedish farmers.

Slamfärger och dess miljöpåverkan

The paint market of today is a jungle whit an enormous range of different paint types; there all has different properties and different compositions, some with big influence on the environment and some whit less influence on the environment. It could even be difficult for an expert to always know what should be used on which surface and what would be the best out of the environmental point of view.This work is not intended as a total review of all the manufactures range of colours; only as a deeper dissertation about distemper paint in general, in particular Falu Red Paint. Whit focuses on the environmental issues.The work is especially for those who are ready to paint but don?t know what paint they should chose and people that has a interest in paint and environment, perhaps it also could be of interest for professional painters even when there probably isn?t any big news for them. The information is compiled from the Internet and downloaded brochures from the Internet..

Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR

The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Säkert sittande - Ett produktutvecklingsprojekt mot Innovationsslussen i Västra Götaland

A thesis directed towards Innovationsslussen in Gothenburg about securing, improving and simplifying sitting on the toilet for patients with sitting difficulties. The primary target group for the project is patients who have had a stroke and as a consequence from that suffers from various kind of bodily paralysis.An overall goal was to design an aid that was comprehensive enough that the patient could manage sitting securely on the toilet without have a nurse giving physical support during defecation.Five conceptual proposals were developed and evaluated in consultation with Innovationsslussen and one was selected to be further developed.The result was an integrated support at the toilet that facilitates a good sitting posture which minimizes the risk of falling and provides comfortable support when leaning to the side. The product is divided in two with both a redesigned carryingsystem and a new type of support surface adapted for the purpose..

Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Downloading and filesharing through Peer-to-peer networks: the copyright versus the free access to the cultural products

The “peer to peer” (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success. Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold today the top ranks and concentrate large traffic: eDonkey and eMule.
