Utvärdering av traktplanering på Holmen Skog
This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region.
For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn.
It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams.
The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient.
One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..
Metaheuristic Multiple Sequence Alignment Optimisation
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
Personer med Multipel Skleros upplevelser av att leva med sjukdomen, samt deras upplevelser av stöd och bemötande från vårdgivare : En intervjustudie
The aim of the study was to describe what it's like to live with Multiple Sclerosis (MS) and experiences of social support and being received and met by health personnel. The method was a qualitative interview study of descriptive design and was analyzed using qualitative content analysis. Three women and two men (26-75 years) with MS from two municipalitiesin central Sweden participated in the study. The main results showed that the participants felt the disease limited everyday life. The majority described feelings of injustice being affectedby the illness, but they now have a new perspective on life.
Multipel Skleros En kartläggning av infektionskomplikationer i samband med hematopoetisk stamcellstransplantation
ABSTRACTMultiple sclerosis (MS) is the leading cause of adult disability inSweden. Hematopoietic stem cell transplantation (HSCT) can be used as a treatment option for patients with MS where the disease has an aggressive course. The treatment is preceded by high-dose chemotherapy which lowers the patient's immune system. It is therefore of interest to study infectious complications associated with HSCT in this patient.Aim: The purpose of this study was to identify infection problems in this population associated with HSCT, and to study differences in infectious complications between this group and patients diagnosed with lymphoma who have undergone the same treatment.Method: The study was a retrospective descriptive study with quantitative data. A medical record review was conducted.
Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
Systerskap i två amerikanska romansviter för unga kvinnor : en jämförande analys av Louisa May Alcotts Little Women, Good Wives och Ann Brashares The Sisterhood of the Traveling Pants.
The purpose of this Master Thesis is to compare two American novel suites for young women, Louisa May Alcott?s Little Women and Good Wives to Ann Brashares series of The Sisterhood of the Traveling Pants. The social status of women and children in the US during the 19th century is analyzed and compared historically and literary with the situation 130 years later.The main question is, what differences exist in the books and is there a connection between the changes in society and literature?The method of this Master Thesis is to make a comparative narratological analysis placed in a historical context.The result shows that the multiple character remains and enhances the identification process. Motherhood in the works of Alcott is prominent, whereas in the works of Brashares, sisterhood replaces motherhood.In Alcott?s US during the 19th century, Christian faith was in the foreground.
Power supply monitoring for wireless sensor platforms
Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Att fly sin kropp. En studie om gränsöverskridning i Sara Stridsbergs prosa
Sara Stridsberg?s novels Happy Sally, Drömfakulteten and Darling River are all brimming withliterary images of movement and becoming. The physical aspects of being a female subject inbecoming highlights the enfleshed body as important. Themes such as sexuality, power andviolence can be traced in the beautiful but most disturbing narratives of Stridsberg.The purpose of this study is to show the reader how the literary female characters aretranscending the physical borders of their bodies in order to become something more than what thehuman form allows them to be. Heteronormative sexuality, sickness, closeness to water andanimaling are bound together by the way they enact the female characters to stretch beyond thesurfaces of their skins.

Att genomföra projekt - Två teoretiska perspektiv på ett problemfyllt projekt i ett kunskapsföretag
This thesis examines a project that has been conducted at a software development company. The aim is to investigate which problems firms of this kind faces performing projects. We choose a theoretical frame consisting of a modern view on how to manage projects. The view argues that the management of each project has to be adapted to the situation at hand. This theory is divided into two separate streams of reasoning; one emphasize learning, delegation of responsibility and flexibility, while the other argues for control, time planning and the importance of keeping to the plans.When we compare the theories to the case we draw three main conclusions: A thorough phase of investigation is required to produce the necessary planning documents.
Tankefel, vad är oddsen för det - En studie om konjunktionsfel bland konsumenter inom vadhållning på sportspel
Several studies have shown that people misjudge and fail to correctly combine probabilities. An explanation for these tendencies is the conjunction fallacy. Basically, the conjunction fallacy refers to violations of the conjunction rule, which states that the probability of a combination of two independent events (A & B) cannot exceed the probability of neither event (A or B). In connection with the growth of the Swedish gambling market and the fact that betting is an everyday-event containing well-defined probabilities, it is considered to be both up-to-date and relevant to study whether the conjunction fallacy also occurs in betting. Previous studies have shown that people fall victims of the conjunction error, however, only in controlled laboratory settings.
