Ro Rollytech AB är ett företag med visioner om ett nytt träningssystem för rullskidåkare, där åkaren ska kunna samla in data under träning/tävling och sedan få möjligheten att utvärdera denna efter passet. I ett samarbete mellan Luleå tekniska universitets avdelning för Industriell design och Institutionen för systemteknik fick Rollytech under våren 2006 chansen att påbörja arbetet med sin idé. Ett digitalt träningstillbehör skulle utvecklas utrustad med en touch screen för navigering och med teknik som skulle möjliggöra trådlös kommunikation mellan träningstillbehöret och en rullskida. Den rullskida som skulle användas var en ny del av Rollytechs sortiment: en skida i glasfiberkomposit som Rollytech samtidigt hade under utveckling i företagsorten Öjebyn. Arbetet med att ta fram tillbehörets skal skedde genom ett examensarbete av Alexandra Teterin och Erika Hedvall som avslutning på deras studier i Industriell design.

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

Heart failure is the most common reason to hospitalization among persons over 65 years old. Self-care is an important part in the treatment of heart failure, but poor information and knowledge limits the ability of self-care and increases the risk of admission to hospital.The aim of the study was to investigate what information patients with heart failure describes that they receive from health care personal, how information is perceived, who provides the information, and on what occasions it is given. The aim was also to investigate whether patients' perception of knowledge about heart failure increased after hospitalization.The study is cross-sectional study with a descriptive design. A consecutive selection was used. A questionnaire was filled in by 28 participants.The study has shown that patients with heart failure largely experience information about heart failure inadequate.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

Previous research has shown that children with multiple disabilities have been able to learn to make choices. Practising choice making is a good way to introduce an intervention using Alternative and Augmentative Communication (AAC). Choice making with objects should then be trainded before choice making with pictures. The present study is a single subject experimental design and was accomplished at a center for children with disabilities in Tanzania during 12 weeks. The primary purpose was to examine if the number of choices made by two boys with cerebral palsy increased after communicationintervention with objects and pictures.

A new curriculum, entailing news for teachers as well as students, was implemented in 2011. Among other things History has been given a more prominent position in that every student will now study the subject. Can this decision lead to history being used more in the future?The aim of this thesis is to study the new curriculum, Gy11, as well the Lpf94 and Lgy70, based on Klas-Göran Karlsson´s typology where the use of history is divided into seven different categories. I will analyze the curricula, looking at what different uses of history that can be discerned as well as what changes have been made over time.

The web as an arena for news reporting and information sharing to consumers has grown for many years in the expense of the traditional newspapers. The revenue stream has however not followed the same transformation which has led to a remarkably lower profit when news and articles are distributed through the web. Banner advertising is a method that is commonly used by online magazines to generate profit where advertisers pay to expose their message. One method to measure banner ads effectivity, and indirectly, what the advertiser would pay, is through Click-Through Rate (CTR), how many clicks a banner ad receives in relation to the amount of banner views. One of the variables that play an important role in the banner ad effectivity is the placement of the banner ad.

AbstractIntroductionWedged shoe insoles are used as a treatment for different problems in order to change the ground reaction force. They can secondary cause different loading patterns under the foot compared to normal. No previous study has, to the author?s knowledge, clinically evaluated the plantar foot pressure with different full-length wedges in normal persons.PurposeThe purpose was to evaluate the plantar pressure with different degrees of full-length wedges in normal persons.MethodTwenty persons with normal feet have participated in this single blind study. Wedges were produced clinically in four different shapes, 3° valgus, 0° flat, 3° varus och 6° varus.

Genetic defects are caused by mutations in major genes where the gene?s protein product has a large impact on the physiology of the animal. The synthesis of the protein can be altered by a change in the nucleotide sequence, which can lead to malformation and in many cases death.One of the main reasons of increase in many genetic defects is the use of few bulls in breeding programmes, causing a reduction of the genetic variation. Genetic defects cause suffering for the animal and influences the production by, for example, increased costs due to misscarriages, lost milk production and expenditure for medical treatment. Bovine Leukocyte Adhesion Deficiency (BLAD) and Complex Vertebral Malformation (CVM) are two genetic defects that were widespread before the causative mutation was discovered.

Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..

ABSTRACTBackground: Children and adolescents growing up in families where parents have serious problems are exposed to an increased risk of developing poor mental or physical health themselves. In a support group work they can meet other children in the same situation, receive help and support to process their emotions and manage their everyday life.Aim: To investigate if support group work at Trappan can reduce the psychological problems load and increase the experience of life quality, hopefulness and optimism in children and adolescents growing up in families where either addiction or mental illness occur in one of the parents. The purpose was also to investigate if there was any difference between these both child groups regarding psychological problems load, experience of life quality, hopefulness and optimism before and after support group participation.Method: Questionnaire study on children and adolescents of parents with addiction or mental illness. The children participated in support group work at Trappan. The measuring?s were conducted before and after support group participation.Results: In both groups an increased life quality in connection to finished support group participation was observed.

The development of technology and the mechanization in the Swedish forestry has during the last 60 years resulted in depopulation of the country side and due to that the amount of distance forest owners has increased. Therefore the forest companies need to make some adjustments in order to keep the distance forest owners as customers and to attract new ones. The purpose of this essay was to examine and analyze the distance forest owners satisfaction with Södras service offering and quality of service and further develop some proposals for action. A web-based survey was sent out to 634 distance forests owners in Stockholm, Sweden, all members of Södra. 269 respondents participated in the survey and of them, 27 did also participate in a follow-up telephone interview.

As students of graphic design the craft of print is close to our hearts. One of the most essential mediums of the evolution of printing techniques is the poster. In a world where digital mediums are being utilized to a greater degree everyday, our love for the printed poster makes us wonder if the days of the poster are counted.What we did was to take a closer look at the role of the poster in promoting events. We focused on the Stockholm area and did qualitative interviews with three different event promoters. Live Nation which is an international live entertainment promoter, Dramaten which is one of Sweden?s most well respected theaters and Stockholm Live which is a stand up comedy promoter in Stockholm city.From doing this we learned that economics play an important part in defining the role of the poster.
