The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.

The accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment.

The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.

Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested. Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the conventional methods used today. The study was conducted over a three week period. Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe. The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of conventional methods.

Intangible assets are often a significant part of Swedish companies? assets. Most of these are accounted for as goodwill, arising from acquisitions. After EU:s decision to adopt IFRS as the new accounting standard, intangible assets will to a larger extent be recognized separated from goodwill. This thesis aims to quantify this change and to analyze what specific intangibles are affected most by the transition to IFRS.

Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

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.

As technology have continued to develop over the latest decades and become more advanced the pressure on the general citizens understanding of technology becomes a essential part to live in our society today. The transition have affected our society in great ways and have made a great impact on different groups, one of them being the elderly population in our society. The purpose of this study is to examine how the fast technological development in the latest decades have affected the elderly in our society. This from their perspective by gathering empirical data through semi-structured interviews with elderly people involved in the Agnes-project, a research project focused on improving the general quality of life for older people and increase their knowledge about technology. The study has shown that after the older peoples time involved in the Agnes-project their quality of life had improved in different areas. Areas such as increased cognitive activity, increased interest in new technology and an improvement in their communication with friends and family.

In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.

My aim with the experience-based essay is that I want to explore the implications of mathematics on children's development. I also want to examine my approach in relation to the various mathematical tasks. Why do we think that mathematics is important for pre-school children? What does the research say about how the teacher is thinking about mathematics? Can the teacher combine playing and learning and create meaningful moments and activities related to mathematics? I also want to explore our policies and the objectives that the teacher should relate to. What is required of me as a teacher in order to meet those goals?My essay is about mine and my boss?s view of the mathematical tasks that I usually perform in the preschool.

En kvalitativ studie har genomförts på tre kampanjbilder från IQ-initiativets satsning ?IQ student?. Kampanjbilderna har ett motsvarande tema baserat på att det alltid finns en anledning till att dricka alkohol. Studien har med hjälp av fokusgruppsintervjuer och en intervju med IQ tagit reda på hur IQ vill att studenterna ska tolka bilderna och hur studenterna faktiskt tolkar dem. Studien utgick från teorier som receptionsstudie, semiotik och socialpsykologi.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

Since Sweden became a member of the European Union (EU) several constitutional reforms has been taking place. During this time, Sweden has also changed its view on democracy,from a collective to an individual perspective of democracy in the politics. A reasonable hypothesis and the purpose of this essay is to investigate if the Swedish government has beendeveloped towards an Europeanization.The Swedish state audit changed in a pioneering way after the EU- entry, with the formation of Riksrevisionen. Another constitutional change is that the Swedish EU- membership is being instituted in the Swedish constitution. The role of Swedish courts has also changed since the EU- entry.
