Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

This essay examines how art could be used to bring forth and clarify the Catholic doctrines of purgatory. The research questions are: ? How are the Catholic Church?s doctrines of purgatory illustrated in art? ? How can the paintings affect the viewer and his/her notion on how to shorten the time in purgatory? How can art itself be used as a tool to achieve that goal? The timeframe of the chosen paintings is mainly 14th to 16th century but an overview of how the purgatory has been illustrated after that time until the present is also given. In order to answer the first research question, a painting from the 14th century has been analysed, using a method inspired by Patterns of Intention - a theoretical framework formulated by Michel Baxandall. A reception theoretic perspective according to Kemp, is used on a painting from the 15th century to answer the second research question. The results show that purgatory is illustrated as fire and the souls are depicted as living people, despite that a spiritual condition is visualized. The viewers at that time found the descriptions frightening, but the paintings also revealed ways of being granted indulgences, that is shorten-ing the time in purgatory. These ways were praying, making pilgrimages and giving alms.

Voice onset time (VOT) är en akustisk tidsparameter som reflekterar den tidsmässiga samordningen av talmotoriken. VOT betraktas som det mest pålitliga akustiska kännetecknet på huruvida en klusil är tonlös eller tonande.Föreliggande studies syfte var att studera och jämföra VOT hos svenska barn (8, 9, 10, 11 år) och vuxna för att se hur utvecklingen sker samt för att ta fram svenska normvärden. Ljudinspelningar genomfördes på 150 barn och 36 vuxna vid uttal av de svenska klusilerna i minimala par. Akustiska analyser av materialet utfördes sedan.Resultatet visade att de tonlösa klusilerna föreföll produceras med vuxenlika VOT-värden från och med cirka nio års ålder. De tonande motsvarigheterna producerades med vuxenlik VOT omkring tio års ålder.

This reports goal is the give BSR AB more information that's useful towards their customers in marketing of their products.It involves tests of different air filters designed for cars and 3D-modelling of Opti-Flow systems. The three models thats being tested is SAAB (93SS), VAG (1.8T) and Volvo (S60). To every brand there are three different models. A orginal- , sport- and an open cone air filter (Opti-Flow).The results indicate that the open Opti-Flow filter has better performance compared to the other cased filters. The sport filters for SAAB and Volvo has better performance then the original filter.

The aim of the study was to describe parents' experiences of empty nest. The sample consisted of individuals who had experienced one child moving out of the parental home. Data were collected through qualitative semi-structured interviews and were analyzed by using thematic analysis. The thematic analysis revealed four themes, Concerns about the new time in life, Changing roles, Socializing in the family and Testing the relations. Due to the themes participants' stories reveal anxiety facing the time that will come when children takes the step to leave the nest.

Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

Sahlgrenska Academy at University of GothenburgDepartment of Department of Internal Medicine and Clinical NutritionAbstractTitle: Does coffee consumption affect the risk of stroke?Author: Jenny KällSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012___________________________________________________________________________Background: The widespread consumption of coffee worldwide makes this drink interesting to study from a public health perspective. Even minor health effects may be important for the whole population. Stroke patients require the largest number of days spent in hospitals and nursing homes than any other medical condition group. Risk factors for stroke include smoking, high alcohol intake, physical inactivity, hypertension, hypercholesterolemia, high waist-hip ratio and diabetes.

Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

AbstractThe purpose with the study is to contribute knowledge of teacher?s thoughts of, and actions in potentially stress filled situations at preschool. The methods I?ve been using are qualitative interviews and unstructured observations of hallway situation at dressing and the transit between lunch and rest.At the interviews with the teachers it showed that none of them feels stressed but there are stress filled situations. The lunch and transit between lunch and rest is a stressful situation, where there is a lot to do, like the dishes, the teachers break and the lie-down.

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

This report is a study made at Pallco AB.
