Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län
The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..
Betydelsen av näringstillskott för läkningen av trycksår: En evidensstudie
Nutrition är en viktig och central del av människans liv. När man inte får i sig tillräcklig mängd näring kan det få allvarliga följder så som malnutrition, ett tillstånd som ofta sätts i samband med trycksår. Trycksår orsakar lidande både fysiskt och psykiskt för de som drabbas och har därigenom påverkan på deras livskvalitet. Syftet med studien var därför att söka evidens för betydelsen av näringstillskott för läkningen av trycksår. Evidensstudien baserades på nio vetenskapliga artiklar.
Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm
Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years. Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed. Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.
Hedersrelaterade problem i en mindre kommun
Our purpose was to investigate which readiness, different sectors in a minor city has to meet honour-related problems. We wanted to investigate how they manage honour-related problems and how the co-operation in these cases is between different authorities. Our questions at issue were: Which knowledge's, experiences there are about the culture of honour, which resources has the authorities and how is the co-operation between different organisations work?We have collected present documentation and research about the subject. We made eight quality interviews with different persons within professions, as we understood, came in contact with cultures of honour.
A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking
The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.
Den informella organisationen : Jämställdhetsutredning inom bank-och finansbranschen
During the autumn of 2007 I carried out an investigation within the bank and finance Sector. The aim of the investigation was to see how informal aspects could be understood in relation to equality within Bank AB? The main question was: Which are the obstacles and opportunities for equality within Bank AB? To answer the main question I asked the following questions to the material: Are there any gender related different within the organization? How are men and women represented within the internal magazine? Which are the conceptions related to sex/gender within the organization? The investigation is based on a survey, the internal magazine was investigated and finally interviews took place. Throughout the investigation I used organization theory in a gender perspective. With the gender organization theory I examined concepts as structures, leadership, symbolism and changes associated with equality.
Goat production in Laos and the potential of using Erythrina variegata as a feedstuff
Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.
Planteringsförbandets inverkan på bildningen av kärnved hos tall (Pinus sylvestris L.) : en modellsimulering av planteringsförbandets inverkan?
The current state of knowledge indicates that there is more than one factor that initiates heartwood transition. This study supports its hypothesis on the theory that heartwood is formed by a fixed fraction of the annual growthring, 0,5 to 0,8 rings. To calculate heartwood volume modelings were carried out in four different pine stands with different spacings, 0,75, 1,25, 1,5 and three meters. The model indicates heartwood diameter (HWD) and is based on four explanatory variables, height (H), crown ratio (CR%), diameter breast height (DBH) and tree height (TH). The shifting plant spacing results in varying growth rate in the juvenile stage.
Patienters upplevelser av att leva med cancerrelaterad smärta : En litteraturstudie
Background: Cancer-related pain is a major problem worldwide. Studies indicate that patients do not get an adequate pain relief. This creates a large suffering and results in major problems for the patient and their families. In order to minimize this kind of suffering caregivers need to understand how cancer-related pain is experienced by these patients, what it does to them and how it impacts their daily life. Aim: The aim of this study was to describe patients´ experience of living with cancer-related pain.
Hunter demography, trends and correlates of hunting participation in Sweden
The concerning issue of declining number of hunters in North America is also apparent in Europe and Sweden. When the bulk of research found on human dimensions and hunting participation has almost exclusively been done in the United States, this report seeks to add to the needed knowledge on a national level focusing on the causes of hunter declines related to social factors within Sweden. Using hunter data reaching from commune, county to National level, this report describes the correlation between a number of variables and the hunting participation in Sweden.The typical Swedish hunter lives in an area with low population density, the person usually has higher education, the living situation is stable with no recent moving and there is relatively good access to forest land. Persons with weaker connection to the Swedish culture such as foreign citizens, people with foreign background and people born outside ?the Nordic countries? are less likely to start hunt or participate in hunting.A strong relationship was found between the favorite game, moose (Alces alces), and the amount of hunters participating in the hunting.
Analys av tanniner : från granbarksextrakt
The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.
Vem är hon? En analys av identitetskonstruktionen av asylsökande kvinnor bland Migrationsverkets tjänstemän
When gender-related refugee claims was ratified in the Swedish asylum law the 31 of March this year (2006) it opened the door for women with this specific refugee status to receive asylum in Sweden. The aim of this thesis has been to investigate how these specific female refugees are represented and described in the asylum process. The focus has been the construction of identity concerning these women in the Officials discourse at the Immigration department. The theoretical framework has been a critical discourse analysis regarding the exercise of power and dominance connected to the construction of identity.An understanding of the women with gender-related refugee claims as the Others has been perceived through the Officials discourse. Female refugees which have been exposed to persecution that occur in our part of the world (rape, wife abuse, etc.) are treated differently and much more restrictive, compared to women exposed to so called culture specific oppression (e.g.
Får sjuka äldre patienter i sig tillräckligt med näring till lunch och middag?
SAMMANFATTNINGBakgrund Undernäring är vanligt förekommande bland äldre i Sverige varav en orsak är att de äter för få måltider och har dålig aptit. Det är därför viktigt att de äldre erbjuds tillräckligt många mål mat per dag och att maten är energi- och näringsriktig. Sjuka, undernärda äldre behöver ofta äta energi- och proteinrik kost för att uppnå sina behov. Det är viktigt att motverka och behandla undernäring då det kan medföra bland annat försämrad livskvalité. Med denna studie ville vi ta reda på och belysa hur de äldres näringsintag verkligen såg ut.Syfte Syftet med studien var att studera intag av energi, protein, järn, kalcium samt C och D-vitamin under två huvudmåltider, två dagar hos geriatriska patienter som åt E-kost.Metod Metoden som användes var en vägd kostregistrering samt fotografering.
Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper
The dissertation were performed on SP, Technical Institute of Sweden.
The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal.
One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow.
Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible.
The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics.
For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.
