Indirekta effekter på marklavars abundans och diversitet vid ökad kvävehalt i marken : en jämförelse mellan opåverkad och lågintensivt brukad mark
Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems.
We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.
Framgångsfaktorer och hinder med Lean produktion i Kina
AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.
Varfo?r finns det sa? lite svensk ekologisk frukt? : probleminventering av den svenska ekologiska fruktbranschen
Out of totally 1862 hectares of the Swedish fruitacerage, only 142 hectares are cultivated
according to the EU-standards for organic farming. Only 73 hectares are connected to the
Swedish control organisation KRAV. Therefore only fruit from this acreage can be sold as
organic.
The aim of the study was to further investigate the organic fruit production regarding
cultivation, market and firm strategy.
Through interviews with 36 fruitproducers the situation for organic fruit and the companies
were examined.
NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
Kommunalt naturskydd som en del av markanvändningsplaneringen : en fallstudie av olika synsätt i samband med upphävande av naturreservat
In metropolitan areas where the exploitation pressure increases, also the importance to point out nature areas grows, both for the sake of outdoor life and for biodiversity conservation. Since nature conservancy and spatial planning constitute two different parts of the municipalities land use control, a case study has been carried out in two municipalities in the Stockholm region, Huddinge and Järfälla. Both these municipalities have protected about one third of their land and today there are plans to repeal parts of the reserves to enable exploitation. This thesis shows ? from the theoretical concept of sustainable development ? officials, politicians and non-governmental organizations perspectives on questions concerning land use together with the work with nature reserves and repeals.
Samspelet mellan naturbaserade arbetssätt och specialpedagogik: En kritisk studie
AbstractThis essay aims to problematize and illuminate the connection between special-education and nature-based activities. With a theoretical ground that is based upon a sociocultural perspective I consider the information from the field. Through a qualitative and critical perspective I performed individual interviews with five pupils from the sixth school-year in the Swedish elementary-school. I also performed Focus-group interviews with two educators and three teachers in the same school-form. By a Hermeneutical working-method I have found out that the informants in my survey have a common experience that activities performed in nature has a positive effect on learning.
Övervakning vid allmän anestesi och stående ingrepp på häst
The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed.
The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.
Vibrationsträning vid knäledsartros
In cooperation with Hälsoteamet Halmstad a pilot study was made to see if whole body vibration exercise has any effect on muscle strength, movement and experience of pain in people with knee osteoarthritis. Today whole body vibration exercise is a revolutionary exercise method that needs more studies to show the positive and negative effects. Osteoarthritis is a degenerative disease where more cartilage is destroyed than replaced. The most common symptoms are pain, stiffness, restricted movement, muscularly atrophy, tenderness and instability. The cartilage needs pressure to rebuild, it is therefore important that the patient exercise.
De bortglömda stenarna : om byars äldre gränsmarkeringar och rågångar i Ekeberga socken
This essay is about the hamlets´ older boundaries, i.e. boundary lines (?rågångar?) and boundary markers in the form of rocks, and an own survey of two hamlet boundaries in southeast Sweden. Many of the boundary rocks were subjected to unintentional damage or destruction that arose during forestry activities, the excavation of ditches, or road construction. Boundaries between hamlets sparsely populated areas were not clearly defined from the beginning, but were established initially in the form of boundary zones, that often consisted of wetlands, watercourses, or mountain heights.
Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet
General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
?Jag är en vampyr? Om unga kvinnors identitetsskapande i det senmoderna samhället
The purpose of this Master?s thesis is to investigate if there might be a possiblecorrelation between young women´s fascination with the vampire narrative andtheir search for identity in the late modern age. With the help of contemporarysociological studies in the field of the late modern man and today?s youth culture,I?ve chosen to do qualitative interviews with eight young women in order to examinehow today?s society affects their process of identification. Lately we?ve been ableto see an enormous interest for books that deal with the vampire saga, and while thereaders are mostly young females, it brought me to ask the question why the combinationof teenage drama and vampires seems to be such a winning concept.We live in a time where most young females experience a lot of pressure trying to addup to the demands of society, and as the media keep producing images of youngwomen being thin and looking like supermodels, most teenagers feel a lot of pressureand anxiety trying to live up to such unnatural ideals that in the long run might lead tovarious health issues and eating disorders.As a result of this thesis I?ve found that the vampire narrative answers to some ofthe existential needs we have as members of a late modern society.
The possibility of applying Low Stress Stockhandling in reindeer
The purpose of the study is to investigate the interest in Sami reindeer herders to use the Low Stress Stockhandling (LSS) method for handling reindeer. Also to find out which reindeer handling situations they think works the best and the worst, and which might need improvement. The purpose of LSS is to reduce the stress animals are subjected to during handling by creating consistent and calm responses from the animals. This is done by handling the animals through the animals? point of view and using natural herd behavior to accomplish this.
Det förbryllande sambandet mellan risk och avkastning : En studie av de nordiska finansiella marknaderna
Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.
Utvärdering utav effekten av obturatbehandling vid restspalt/fistel hos barn med total läpp-, käk- och gomspalt
On children born with a complete cleft lip and palate (CLP) the repair of the alveolar ridge doesn´t take place before the children are about ten years old. This results in that they have a residual cleft in the alveolar ridge during their early childhood. This residual cleft, and the oronasal fistulas that may appear after the repair of the hard palate, can result in a negative influence on the speech of the children. Thereby it may be necessary with cover for examplewith a palatal plate or an obturator. At the Department of Orthodontics, at Linköping University Hospital, Sweden, some of the children with CLP undergo treatment with sustained palatal fistula obturation in order to cover fistulas or residual clefts.
