Plan för multifunktionella buffertzoner längs Vramsån på Malörten AB: s jordbruksfastigheter

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses. As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

MÄNNISKORS ERFARENHETER AV VÅRDEN KRING EN GASTRIC BYPASS OPERATION : En intervjustudie

The share of human beings with overweight or obesity is increasing. This has become a problem for society since obesity often leads to illness. This illness affects life negatively and often leads to depression, absence from work and medical care. One treatment against obesity is to do bariatric surgery, or Gastric bypass. The purpose of the study was to illuminate the experiences of care encompassing Gastric bypass surgery.

Metaller i dagvatten - Effekter i recipient : En analys av koppar, kdamium och zink i dagvatten från en parkering i Halmstad, Sverige

When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.

Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

Arbetet inom skolan för att förebygga mobbning

My purpose in this work was to find out how staff in a middle sized school uses its local Equal treatment plan in its work against bullying. But also to see how the use of a standardized anti-bullying program works to prevent bullying. I have interviewed the principal, teachers, and what we in Sweden call a ?fritidspedagog? and the members of the anti-bullying team to get answers to my questions.  The conclusion of this study is that the school follow and work according to what the Equal treatment plan states, both in terms of prevention, as in working with actual bullying cases. The school has also followed the National School Agency's recommendations on what should be the local Equality plan, but also to follow up and revise it each year. The interview shows that the staff at the school placed great emphasis on talking and discussing with students about how to behave towards each other, they also brought up things that happened at one time and talked about this. The staffs were very committed to work towards the prevention of bullying and the same was true with the school's headmaster.

Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :

Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.

Analys av kvalitet i en webbpanel : Studie av webbpanelsmedlemmarna och deras svarsmönster

During 2012, the employer of this essay carried out a telephone survey with 18000 participants and a web panel survey with 708 participants. Those who partook in the telephone survey were given a choice to join the web panel. The purpose of this work is to study the participants of the telephone survey and see if they reflect the Swedish population with regards to several socio-demographic factors. Also, we intend to investigate if the propensity to join the web panel differs for participants of the telephone survey with regards to various socio-demographic affiliations. It is also of interest to study if the response pattern is different for participants of the telephone survey that would like to join the web panel and those who reject.

Keywords used were quality of life, treatment outcomes, emotions, pacing and life. This resulted in nineteen peer rewieved articles that were selected for the study results. The results showed that patients undergoing a pacemaker implantation experienced an improvement in their physical health with increased functional status, more energy and strength.

Ätstörningens ansikten : en kvalitativ studie om upplevelser och erfarenheter av att kunna anpassa sig till ett friskare liv

This is a qualitative study which purpose is to examine the experiences of the recovery process after a treatment for eating disorders.                                                         The questions we have decided to examine are; how did the women adapt to a healthier life after treatment, what are the women's perceived experiences of the aspects related to identity and identity work, and what external social influence was seen as important for their adjustment process to a healthier life?Methods: We have used computer-supported and semi-structured interviews. There were a total of nine women who took part in the study.                                                                                                                    Results: Majority of these women have been recovered from their eating disorders, but some still have major or minor problems. They found it rather difficult to adjust their life's without an eating disorder.Conclusions: Increased self-awarness led to greater control over the eating disorder. The women could begin to confer the new features that they identified with.

Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Resonans

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

VISION SJÖSTAD : Flytande Bostäder

Floating housing is a concept gaining ground in Sweden. The dwellings are different in many ways from traditional homes, not only regarding flotation, but also several other technologies. The purpose of this thesis is to emphasize the qualities that exist in living on water. The ambition was to present a proposal for a floating residential area located in Jönköping, containing homes of varying sizes, and to present their technologies. In order to find inspiration and solutions studies have been made on existing floating homes in Stockholm and Kalmar, focusing on their technical and functional solutions.

Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten

In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

Behavioral studies in healthy Standardbred trotters subjected to short term forced recumbency aiming at an adjunctive treatment in an acute attack of laminitis

Laminitis is a debilitating disease causing much suffering to horses and ponies all over the world. It is manifested in the hooves as a mechanical failure of the suspensory apparatus between the hoof capsule and the distal phalanx. Due to the weight of the horse the disease may result in a dislocation of third phalanx. Six healthy standardbred trotters were used in this study on whether standardbreds tolerate forced recumbency as well as Shetland ponies. Recumbency was induced pharmacologically but maintained only by lowering the ceiling height of the box to a height of approximately 125 ? 140 % of the horse´s thoracic height.

Metanpotential för alger och bioslam blandat med pappersfiber

In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
