Hårdhetsvariation i grundvatten längs Badelundaåsen mellan Leksand och Avesta

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Tidig postoperativ övervakning av smådjur : förekomst av standardiserade rutiner

Background. Anesthetic-related death in small animal anesthesia is about ten times more common than in human anesthesia. Recent research identifies the early postoperative period as particularly risky and highlights the need for regular and careful monitoring of the veterinary patient during this period. Objective. The aims of this study were to investigate whether there are standard procedures in terms of regulated routine patient observations and record-keeping during the early postoperative period at Swedish veterinary clinics, and if there are any guidelines for monitoring the veterinary patient during recovery. Methods. A small survey including ten Swedish veterinary clinics was carried out as well as a literature review. Results.

Trettio år av jämställdhetspolitik : Från kvinnor i arbete till jämställdhetsintegrering

Thirty years of gender equality politicsFrom women?s work to gender mainstreamingThis Bachelor thesis examines how the Swedish state has practiced gender equality as a political project during 1972 until 1999 through the budget bills, using a ?What?s the problem represented to be?? approach aiming to uncover which discourses policies are based on. The method also studies what assumptions underlie policy problems, what is left as unproblematic within the policies and what effects are produced by specific problem representations. A central question for the thesis is what has remained and changed within Swedish gender equality politics. The history of the Swedish welfare state is presented as a background on how gender equality policy has affected the everyday life of women and men.

En studie av fysiska, organisatoriska och individuella riskfaktorer hos arbetstagare med datorarbete

Musculoskeletal disorders (MSD) are common in individuals with computer based work. Thecurrently known risk factors for these disorders is in the literature derived to physical,organizational and individual factors. A recent survey of three working groups at a companyin Stockholm explored that more than 50% of the employees had neck and shoulder problems.Aim: The study aims to create a better understanding for the current musculoskeletalproblems at the company. Such an understanding is created by examining the physical,organizational and individual risk factors in the workplace and the result can provide a goodbasis for intervention proposals.Method: In order to answer the aim of the study the authors chosed to use both qualitativeand quantitative methods of data collection through interviews and questionnaire survey. Theinterview and questionnaire was designed to create both a specific and comprehensive pictureof the physical, organizational and individual risk factors having a bearing effect on theexisting MSD problem.Result: Seven categories were compiled from interviews, which largely deals with the factthat high demands can lead to behaviors that may pose a significant risk for the occurrence ofMSD.

En uppföljning av floran i Enköpings vattenpark : kan anlagda våtmarker med vattenrening som huvudsyfte bidra till naturvård och biologisk mångfald?

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Wallenbergare : En jämförelse i sensorisk kvalitet

Inledning Wallenbergare var från början en elegant restaurangmaträtt bestående av en panerad kalvfärsbiff serverad med potatispuré, ärtor, lingon och skirat smör. Rätten torde vara uppkallad efter häradshövdingen Marcus Wallenberg någon gång under 1930- talet. Det finns många historier om Wallenbergarens uppkomst men ingen tycks veta med säkerhet vem som serverade den för alldra första gången.Syfte Syftet med denna uppsats var att undersöka hur val av styckningsdetalj, kryddning, temperatur och mixning påverkar den sensoriska kvaliteten i en Wallenbergare.Metod/material De tre metoder som användes under denna studie var en provmatlagning med en större mängd av variabler, en enkätundersökning gällande tidigare erfarenheter och uppfattningar om Wallenbergare samt en sensorisk bedömning av biffens sensoriska kvalitet.Resultat För att Wallenbergaren ska uppnå en konsistens av hög sensorisk kvalitet bör denna bestå av 75 % malt kalvinnanlår, 25 % kalvbräss, äggula, grädde och salt. En Wallenbergare bör endast smaksättas med salt och nymald vitpeppar.Provernas samtliga ingredienser skall vara väl kylda för att uppnå högsta sensoriska kvalitet. De prover som blandades med handkraft erhöll en lägre sensorisk kvalitet än de prover som blandades mekaniskt.

Fuktåterföring i roterande värmeväxlare

För att ha en chans att ändra trenden med ökande utsläpp av växthusgaser är internationella samarbeten nödvändiga. Därför har EU genom miljökvalitetsmålet Begränsad Miljöpåverkan satt krav på högsta tillåtna utsläpp av växthusgaser. Att sänka energianvändningen för upp- värmning är ett steg i att även sänka utsläpp av koldioxid, som är en av växthusgaserna. Sänkning av energianvändning kan göras på flera sätt, bl.a. genom att öka tjockleken på isoleringen eller återvinna värmen i frånluften. Men dessa åtgärder ska inte helt okritiskt göras.

Implementering av Constant Fraction Detection vid avståndsmätning

This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.

Grazing behavior of Ankole and Boran cattle in an improved herding production system

To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.

Metodik för bestämning av åkerdikens status : fallstudie av ett dike i Munktorps socken

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Skrovlighet, hårdhet och ålder : Hur förhåller sig dessa till varandra i kalla förhållanden i Mellansverige

Idag lever 65 % av världens befolkning i länder där övervikt och fetma dödar fler människor än vad undervikt gör. I Sverige har fetman fördubblats sedan 1980 och idag lider ungefär varannan man och var tredje kvinna av övervikt eller fetma. Svenska studier visar även att ungefär vart femte barn är överviktigt och ett barn av tjugofem lider av fetma. Dagligen kan vi läsa i tidningar och se på tv hur människor kan göra för att gå ner i vikt, även hälsokampanjer och diverse hälsoupplysningar blir allt vanligare. Dock verkar inte detta tillräckligt för att hjälpa människor till en lyckad och långvarig livsstilsförändring.

Laborationsmätning av vindtäthetens betydelse för en väggs U-värde

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.
