Små vatten- och avloppssystem : Möjligheter till inskränkning av verksamhtesområden
This study is focused on small scale water and wastewater handling in Sweden. The study is divided into two major parts; the first describes common methods for water- and wastewater handling and the second part is a case study on three small and expensive systems in Gällivare municipality, in the north of Sweden. In the case study, abilitys for the local government to hand over unwanted systems to the water users is investigated and found to be a plausible solution to cut costs for two out of the three studied systems. In the third case, water and wastewater systems is not recommended to be handed over but other ways of cutting costs are suggested..
Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :
Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as
well as in different diary products for humans. In this EEF-work I have shown that
L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for
breeding. In a breeding stock with 3000 animals some animals had a vaginal
infection with ??haemolytic streptococci group G.
Brunnsviken : Utvärdering av åtgärder för förbättrad vattenkvalitet
Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin. The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.
En Grupp Patienters Upplevelse av Sjukgymnastisk Huvudvärksbehandling
There are several treatment methods that are used by physiotherapists to treat migraine and tension type-headache (TTH). The effects of these methods have been evaluated in previous studies. However, there are few studies evaluating headache patients own perception of the treatment. The purpose of this study was both to examine the patient?s perception of the physiotherapy headache treatment and to examine if the treatment had effect on their quality of life.
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
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.

Inventering av processvattenbalans : fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB
Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult.
Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed
daily. The project is performed at Vattenfall´s district heating power plant in Uppsala.
Information is gathered through discussions, drawings of the plant and guided tours of the plant.
Termografisk undersökning med samtidig analys av rektaltemperatur, hjärtfrekvens, psykiska reaktioner och specifika blodparametrar av häst som behandlats med vibrationsboxen Vitafloor :
A number of studies in human medicine has documented positive effects of whole
body vibration treatment in humans. The Vitafloor system, witch is based on
treatment of horses with vibration, has the purpose to be used in training of
healthy horses and as rehabilitation for horses with injuries in their musculosceletal
system.
The purpose of this study was to analyse what happens with a clinically healthy
horse during treatment with Vitafloor. The methods used is mainly thermography
before and after treatment, but also blood samples, measurement of rectal
temperature, heart rate, clinical examination and observation of psychic reactions
has been done.
Statistic significant changes in skin temperature in hoofs and fetlocks of front legs
has been observed after treatment with Vitafloor. Analyzing of the blood samples
showed a tendency for decrease in Kalium, and two of the horses had changes in
CK. No negative effect has been observed with the treatment of horses with
Vitafloor, and the horses seems to like the treatment.

Med alliansen som utgångspunkt ? Behandlingspersonal och ungdomar om positiva förändringsfaktorer för ungdomar inom institutionsvården
The practice of residential treatment of youth has been up for debate for quite some time. The debate regarding institutional care has voiced concerns regarding the lack of follow-up and evaluation of treatment and its efficacy. It is especially important with additional research on residential treatment conducted from the perspective of those being treated, as well as the treatment providers. This study aims to add to this field of research. The study is based on two empirical studies conducted through qualitative interviews.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Rening av avloppsvatten från biltvättar med filter av torv och inblandad kolaska : en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv
Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns..
Vattenjärnhaltens betydelse för mjölkkors hälsa och produktion :
Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.
Vad är NARCONON? : Synen på behandling inom ramen för en religiös ideologi
The purpose of this essay was to describe the opinions of different religious and non-religious ideologies and aspects of treatment, concerning use of drugs and drugsaddiction, and with a special focus at Narconon. We also wanted to try to understand the connection between professionalism and ideology in their treatment.Our central questions where;· How does the treatment Narconon's provides, look like?· What is Narconon's opinion on use of drugs and drugaddiction?· What is Narconon's connection to the Scientology?· Is there any scientific proof that Narconon's treatment is functioning?· How can we understand the connection between professionalism and ideology in treatment?We made intervjues with six social workers and six intervjues with staff at Narconon. Added to the intervjues, we studied articles and Internet research.From our work and through information we have got from Narconon, we have discovered the need of further research concerning their treatment. Narconon does continuous following-ups when the treatment is finished.
Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :
This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.
