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.

Analys av prostaglandin F2? -metabolit i blodet : indikativt för pyometra hos tik?

Pyometra (chronic purulent uterine inflammation) is a common disease in middle-aged and older intact bitches. The disease most frequently occurs in metoestrus and previous research studies have shown that both hormones and bacteria are involved in the development of the disease. Analysis of the blood levels of prostaglandin metabolite 15-keto-13,14-dihydro-PGF2? (PG-metabolite) has previously been shown to be clinically useful in the differentiation of canine uterine diseases such as pyometra and mucometra. The PG-metabolite concentration has also been correlated to severity in pyometra as determined by hospitalisation length. The purpose of the present study was to investigate if blood levels of PG-metabolite can differentiate uterine diseases such as pyometra from other diseases in female dogs.

Utvärdering av en ny selektionsmetod för hingstsperma : med avseende på membranintegriteten och membranstabiliteten

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Musik och rörelse som vägledningsmetod för ungdomar med ADHD/DAMP

Denna uppsats handlar om musik och rörelse skulle kunna vara en alternativ vägledningsmetod vid studievägledning för ungdomar med diagnosen ADHD/DAMP. Uppsatsskrivarnas huvudsyfte var att undersöka om musik och rörelse skulle kunna användas inom vägledning för att ge dessa ungdomar större möjligheter till ett mer kvalitativt underbyggt val till vidare studier. Undersökningen bygger på kvalitativa metoder genom intervjuer med studievägledare inom grundskola samt en aktiv studievägledare (verksam med ADHD-elever). Vi har också intervjuat en Tomatis terapeut (En metod som tränar hjärnan att prioritera, sortera och hantera sinnesintryck bättre) samt en användare av metoden. Resultaten vi kom fram till var att Tomatismetoden resulterade i stora förbättringar gällande koncentration och uppmärksamhet, samt att kvarvarande effekter bestod i minst sex månader.

Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken

Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain. When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced. Facts about the causes of injection-associated pain have been studied in a literature review.

Riskbedömning vid Saltvikens kopparverk

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

Hur varumärkeskapital kan byggas via apotek : En fallstudie av Ferrosans varumärkeskommunikationsstrategi

Purpose: The aim of this study is to test four different hypotheses from the aspect of the title of this paper. H 1 Consumers trust the pharmacy employees? advice and suggestions for their purchase decisions more than the brand awareness they have received through the companies marketing communication H 2 Consumers are enough affected of a company?s marketing communication to choose their brand even if the pharmacy employees recommend other brands. H 3 Building brand equity through pharmacies can only be successful if the company has built up a trust for their brand among the pharmacy employees. H 4 Without building brand equity the marketing communication strategy for Ferrosan cannot increase their brand value and create loyalty.

Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Chile and Santiago are struggling with heavy environmental problems as a consequence of urbanisation and industrialisation. In the Santiago region the air is seriously contaminated and most of the rivers are classified as heavily polluted.The aim of this thesis is to survey the industrial fluid waste situation in the Santiago region and to make suggestions on technological improvements or process changes. The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor

In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.

Bensylpenicillinnatrium intramuskulärt till häst som alternativ till bensylpenicillinprokain

Bensylpenicillin är den mest använda antibiotikan till häst i Sverige idag. Den beredning som skrivs ut till djurägare är framförallt bensylpenicillinprokain, men många hästar får kraftiga biverkningar av preparatet. Biverkningarna kan vara milda så som skakningar eller nervositet, men kan också bli livshotande. Forskning visar att prokain kan vara orsaken till majoriteten av biverkningar, vilket gör att bensylpenicillin utan prokain kan bli aktuellt att använda för att minska risken för biverkningar och öka djurvälfärden. Att byta antibiotika till trimetoprim i kombination med sulfonamid är ej önskvärt då det antibakteriella spektrat då vidgas.

Föroreningstransport i grundvatten : En modelljämförelse

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

En omöjlig Gud? : en jämförelse mellan gudsbilden i postmodern teologi och östkyrklig apofatisk teologi

In some postmodern philosophy and theology, the view of God has returned to the centre of the discussion. God is seen as a living reality beyond human conception. Some of the contemporary philosophers even relate to the negative or apofatic theology. They often do this as a contrast to the positive theology. The view of God in postmodern theology and philosophy is beyond our rational knowledge.
