Naturhänsyn på slutavverkade hyggen i Östergötlands län.
95% of the productive forest land in Sweden are now being exploited for forestry. The new Forestry Act of 1993 equate the goal of production and the environmental goal which means that the objective for forestry is a sustainable yield, while the biological diversity must be preserved. Recent years results from the inventories of the Board of Forestry show declining trends in how nature conservation aspects taken into consideration at the felling sites.The aim of this study is to investigate what happends with the nature consideration taken at felling sites in the long run. 20 final fellings in the county of Östergötland were re-inventoried 7-9 years after final felling. These felling sites had previously been inventoried before final felling (P0) and one year after final felling (P1) in the inventory Polytax by the Board of Forestry.
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.

"Inte som alla andra" : En kvalitativ studie om en grupp vuxna med Asperger syndrom
Normal children acquire the necessary social habits without being consciously aware of this, they learn instinctively. (Author?s translation from Swedish to English) (Asperger & Frith, 1998, s. 21) This essay is about people who do not learn to socialize, the social habits, instinctively but through conscious learning. We have interviewed three adults with the diagnosis of Asperger syndrome with the aim to let them tell us about what it means to have a neuropsychiatric disability.
Strukturerat lärande genom Action Design Research. En studie om visualisering av behörigheter
As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.
Broms- och styrsystem för möbeljalusier
This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.
Breast cancer stem cells : evidence and contradictory views
This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.
Ledarskap i klassrummet : En kvalitativstudie om lärares syn på ledarskap och sin egen ledarstil
There is no further training in management in teacher education programs, which can create uncertainty among teachers in terms of management. According to the curriculum, the teacher should base it on a democratic approach, but how does it look in real life? The purpose has been to investigate how practicing teachers perceived management and their own leadership style, whether they made conscious choices and if so, whether they then had any purpose in their leadership style. Teachers' views of a good leader and how much influence students have on the teaching, enter into these issues.The survey is based on a qualitative research approach, based on interviews with four active teachers. Although observations were made they did not play any major role in this investigation.
Biologisk reducering av nitrat och nitrit i vatten
During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.
Svensk Kod för Bolagsstyrning - Hur påverkas revisorn?
The first version of the Swedish Code of Corporate Governance was published year 2004, by the code group, Kollegiet, after a mission from the Swedish government. The Code consists a collection of rules and standards about corporate governance and internal control, and the first version was intended to include incorporated limited companies on Stockholm?s alpha stocks, and also listed companies with a stock market value over three thousand million Swedish kronor. Now a few years have passed, and in July 2008 a new, revised version of the Code was implemented, now simplified and shorted, with the intention to include all joint-stock companies in Sweden. The Code contains rules about for example ownership, management commitments, annual stockholders meetings, and the accountant. This study intends to, with a qualitative research approach and an inductive reasoning, through studies of empirics in the subject, review whether the accountant?s profession has been influenced by the Code.
