The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

Shorter hospital stays increases the need for well functioning post hospital aftercare. Persons close to the patient are often involved in the aftercare and need information about self-care. This need is frequently not satisfied. The aim of this study was to investigate if the next-of-kin of patients cared for at the thoracic clinic at Uppsala University hospital, have received information about self-care and how they perceive the information they have been given. METHOD: To investigate this, questionnaires were sent out by mail.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Att flyttas från intensivvårdsavdelning (IVA) till vårdavdelningen kan ur patientens perspektiv leda till olika upplevelser, båda positiva och negativa. Själva överflyttningen kan ge ångest, oro och otrygghet till patienterna men kan också upplevas som positivt och oproblematiskt. Överflyttningen till vårdavdelningen kan vara abrupt eller välplanerat och detta kan påverka patienternas upplevelse och känsla. Studiens syfte var att beskriva patienters upplevelse av överflyttning från IVA till vårdavdelning. Kvalitativ metod användes med intervjuer som datainsamlingsmetod där nio patienter intervjuades.

An environmental review has been carried out at FORIA AB, a transportation- and machine service company, to analyze the company?s environmental aspects from the transportation segment. This report describes the essential background and the methods of identifying and evaluate the environmental aspects. It also describes how the work with the environmental aspects often vary between different actors. The design of the ISO 14001 is intentionally broad in order to apply on all sorts of activities and organizations.

Introduction: Parental involvement is becoming increasingly common in the paediatric health care. Parental participation at home means that parents receive instruction by nursing staff in order to perform a caregiving procedure at home.Aim: To explore parents' feelings about performing caregiving procedures on their child at home, and their experience of instruction about these, and to explore nurses? experiences of their instruction to parents.Method: A descriptive quantitative and qualitative design using questionnaires with statements to be responded by nurses and parents according to scales graded 1-10. The study was carried out during the autumn of 2009 at a pediatric unit in the University Hospital in Uppsala.Results: Ten completed questionnaires from the nursing staff and ten from parents were obtained. The mean assessment of parents' perceived safety and security, and their perception that their questions had been answered ranged between 8,6 and 9,2.

According to the health care law and the national care guarantee, all individuals with mental illness have the right to good health care that is knowledge based as well as to rehabilitation where and when they need it. They also should be able to choose and have control over who is performing the care, including the design of these efforts. The purpose of this study is to investigate patients' experiences of general psychiatric emergency care and the cooperation between outpatient care, inpatient care and the municipality. This study is a descriptive cross-sectional study, conducted with a quantitative and qualitative method. The study is performed in collaboration with Akademiska Sjukhuset and is part of a larger quality improvement project.

Introduction: Balance between the essential nutritive substances is important for aperson to maintain health. The surgical patient can be stricken with conditions, whichhave a negative impact on this balance and can lead to malnutrition. Working as a nurseit is important to identify patients that are malnourished or is in the risk zone ofmalnourishment since 30 % of all patients in hospitals are malnourished.Aim: The aim of this study was to examine the compliance to the guidelines fornutritional assessment and parenteral nutrition on a surgical ward. Also whether thenutritional treatment/-support was reported to the next caregivers if the patient wasmalnourished or was in the risk zone of malnourishment at the time of discharge.Method: 80 patients enrolled on the ward in the beginning of year 2011 were included.Audit of patient records was made according to the hospital guidelines for nutrition andparenteral nutrition and followed a study specific protocol.Results: The examination of the case records showed that the guidelines for nutritionwere partly complied with. Nutritional treatment/-support was reported to the nextcaregivers when needed.
