Tillvaratagande av GROT i skärgårdsnära miljö :

The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications. Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines. In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner. The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase. This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed. Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable.

Bonden i Graven Bredvid - En osteologisk studie av den medeltida befolkningen i Norra Nöbbelöv och deras skador på skeletten

This paper is the result of an osteological study of the skeletal remains uncovered during an archaeological excavation of the medieval cemetery in Norra Nöbbelöv. The purpose of the study is to compare the material from the rural site (Norra Nöbbelöv) with materials excavated from the old medieval graveyards in the city of Lund. The aim is to try and shedsome light on the question of whether there is any difference in the occurrence and frequency of fractures and osteoarthritis in the materials compared. The first section of the paper consists of a short historical background of Norra Nöbbelöv and Lund, a chapter on ethics, general results of the analysis and the methods used. Thissection was co-authored by Ulla Zagal-Mach and Åsa Strandh.

Salmonellosis in Peruvian guinea pig production : a study to evaluate the prevalence of salmonella spp and importance of the disease

In Peru guinea pigs are raised for meat production and salmonellosis is considered as a major problem. Studies have detected salmonella in animals with enteritis and pneumonia. Salmonellosis exists both in an acute and a chronic form. In the rural areas the diagnosis is made according to clinical signs and macro pathological findings at autopsy. The major systems applied for the guinea pig production are often classified as family, family-commercial and commercial. These systems differ in number of animals and how industrialised they are.

Utveckling och implementering av ett audiopejlsystem baserat på tidsdifferensmätning

The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

En undersökning om fallolyckor med gångtrafikanter

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Den planerade undervisningen om det finska kriget : En studie av hur gymnasielärare i Västerbotten och Österbotten planerar att undervisa om det finska kriget 1808-09

This study examines how upper secondary school teachers in Västerbotten and Österbotten plan to teach about the Finnish War 1808-09. The study includes written interviews with nine teachers in Västerbotten and eight teachers in Österbotten, who have answered questions concerning school policy documents, content and didactic methods. The purpose has been to examine whether there is a difference in historical culture in how the war is treated in the two regions. Historical culture is here meant within the prospective history lesson, where the pupils encounter history within certain boundaries.The result of the interview study shows that there are differences in structure concerning the school policy documents, but that these differences on the whole are compensated by the widespread interest in the Finnish War by the teachers in both regions. The differences in historical culture can be found within the construction of the content when it comes to the aftermaths of the war as well as the purpose of the teaching.

Förbättrad Kravhantering med hjälp av Lösningsinriktad Pedagogik

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.
