The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

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.

In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

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.

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.

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.

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.
