Effekten av uteblivna miljöersättningar för anläggning av våtmarker
Environmental subsidies are used as incitements to farmers for development of sustainable land use. In 2014, applications for funding constructed wetlands were not available. This paper examines the environmental consequences of this lack of funding in one intensively cultivated region Skåne län, southern Sweden.A review of wetland applications between year 2007-2013 show that the average rate of applications has been 31 projects per year with a wetland size of 4,48 ± 1,61ha per project (mean±95% CI). Based on interviews, the result suggests that the lack of funding in one year leads to between 102 and 140 ha of constructed wetlands that is not built. This correspond to a total loss of increased nitrogen retention capacity between 6,0 and 91,7 tons/year and a loss of increased phosphorus retention capacity between 0,17and 2,1 tons/year in the drainage basins of Skåne.Further the interviews show that continuity of environmental regulations and funding is important for the farmers? interest in environmental measures.It is concluded that the total loss of increased retention capacity is small compared to the annual transport of nitrogen and phosphorus in the drainage basins.
Skattning av biverkningar : Sjuksköterske- och patientuppfattning om behandlingsrelaterade biverkningar vid stamcellstransplantation.
A possible treatment for patients with lymphoma and myeloma is stem cell transplantation (SCT). SCT is preceded with cytostatic treatment. There are several side effects related to this treatment, for example fatigue, nausea, constipation/diarrhoea, pain, mucositis and loss of appetite. Aim: Investigate which side effects related to the treatment where most troubling after SCT and if nurse assessment and patient assessment differ. Methods: A quantitative empirical study with repeated measuring.
Bakomliggande faktorer till presbyacusis; en litteraturstudie av mindre kända faktorer
Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..
Långvarig neuropatisk smärta : en litteraturstudie om livskvalitet ur ett patientperspektiv
Objective: From the patient?s perspective describe communication difficulties, which can arise, and how they are handled in their contact with public health care and illustrate their needs of communication.Method: A study of literature was carried out to receive a background and an insight in previous research concerning the subject area. Twelve women with hearing loss was asked to complete a questionnaire, with open questions, regarding communication difficulties in health care situations.Sample: For the literature review, scientific papers were selected via the database, PubMed using relevant keywords. Seven were selected for closer review. For the survey study twelve women were asked to participate which ten of those responded.Results: The study of literature shows that communication difficulties occur in public health care between patients with hearing loss and the nursing staff.
KOM LOSS En studie av Läs- och skrivstugans verksamhet på tre bibliotek i Västra Götalandregionen
The purpose of this Master Thesis is to investigate whether the technical service available in the "Reading and Writing Corner" has an influence on the total quality of service in a public library. This service is intended to give sensory/print-handicapped persons access to information. The title KOM LOSS is a Swedish expression for "come on" and LOSS is short for reading and writing support. I have chosen to study three libraries in the region of Västra Götaland, Sweden. The thesis examines total quality from the aspects of goal steering, accessibility, education and marketing.
Beteenden hos geparder i två stora svenska djurparker
Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.
Människans suveränitet över andra arter : En studie om två miljöorganisationers resonemang angående förlusten av biologisk mångfald
The purpose of this study is to exam how two environmental organizations reason about the loss of biodiversity. The research questions are; what is the view in these organizations regarding biodiversity? What are the underlying environmental discourses behind their reasoning, and how do they reason about the risks associated with the loss of biodiversity? As a first part of this thesis a thorough review of existing literature and online resources about the actions of environmental organizations was conducted. Two organizations were interviewed, World Wildlife Fund (WWF) and Naturskyddsforeningen. The questions for the study were analyzed in light of Dryzek´s (1997) reasoning about environmental discourses and using the concept of risk by Beck (1998).
Studier av habitatval och revirstrukturer hos vassångare (Locustella luscinioides) i Tåkern
The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.
Gis och realtids-GPS på renar : renens habitatanvändning i brukad skog - två vintersäsonger i Vilhlemina Norra Sameby
This study is commissioned by the Swedish University of Agricultural Science (SLU - Department of Forest Resource Management) in coorporation with Sveaskog and Vilhelmina Norra Sami reindeer herding community. The purpose of this study is to analyse movement patterns and habitat use of reindeers during two winter seasons (2005/2006 and 2006/2007) in areas affected by forestry activities such as clearcutting. This study examines the possibilities of analysing information from Reindeer husbandry plans and forest variable data from kNN and SMD, in relation to GPS collar points from reindeers by using Geographical Information System (GIS). Lack of knowledge and understanding between the reindeer industry and the timber industry has often led to heated debates. The possibilities of using this type of technique are very interesting and could increase knowledge concerning land-use issues to different resource users.
The main results from analyses comparing SMD, kNN, data about clearcuts, and GPS collar points from reindeers indicates that clearcut areas, younger forest, coniferous forest on lichen-dominated areas and areas dominated by pine was preferred by reindeers during the winter period.
Havsöringens (Salmo trutta) och laxens (Salmo salar) lekområden och lekvandring i Vindelälven och Piteälven :
The population of seatrout and salmon are threatened by over-fishing in the sea
and loss of spawning and growing habitats caused by logging activities in many swedish
rivers. The knowledge of the spawning migration and the habitat use of the seatrouts
and salmon are limited. This study analyse the upstream spawning migration of Atlantic
salmon and sea-running brown trouts from the lower part of the rivers to their spawning
sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of
spawning sites in the rivers will help these fish population in future restoration programs.
In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20
salmon radio tagged and subsequently released and followed during their spawning
migration upstream Vindelälven. They were tracked on their position in the river once a
week.
The Student Habitat : "a small and interactive community where students can live, interact and socialize."
I?ve chosen a subject that's close to my heart, as a student who has experiences the need of a change in the traditional student living.I've focused my theses on ?nding the key ingredients for improving an individuals time as a student. In a time when students are struggling to ?nd accommodation that ful?lls the need of being close to university, close to social places, adequate size and affordable. This is close to impossible! This is not just a problem in Stockholm but an international dilemma.The heart of my thesis is, how can we create clever ways of student accommodation with emphasis on community and a more sustainable way of living?Only when we start embracing change and by breaking out of our traditional individual living, can we then start to realise and recognise the bene?ts of working, studying and living together.
Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding
The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.
Analys av fördelningssystem för bostadshus
The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated. The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.
Bestående viktminskning - en livsstilsförändring inom kost, motion och förhållningssätt
Fetma och övervikt är ett hot mot folkhälsan. Många med övervikt och fetma försöker gå ner i vikt, men få lyckas bibehålla viktminskningen. Studiens syfte var att ta reda på erfarenheter av betydelsefulla faktorer och strategier för en bestående viktminskning, samt motivation för bibehållandet av vikten. Enligt Self-determination theory (SDT) blir beteendeförändringar bestående om de är autonoma och om motivationen är intern. Åtta kvinnor som deltagit i Itrims viktminskningsprogram intervjuades.
Kvinnans och mannens behov vid förlust av ett väntat barn
Background: People are individuals who react differently when confronted with unexpected events. To miscarry is nature?s own way of sorting out the foetuses which could never become a fully grown child. The loss can without help be difficult to handle and can impact the couple negatively towards future pregnancies. The nursing staff ought to familiarize themselves with the experience, encounter their feelings and identify their needs.
