Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

By studying literature concerning design, didactics and reflection, and complementing those explorations with interviews with experienced design educators, this thesis challenges the idea of aesthetic media education being purely aesthetic in its characteristics. Drawing from their own experiences as a media aesthetics educator and an industrial designer, the two authors argue that the work flow used within most fields of design, commonly known as the design process, might provide a suitable didactic alternative to a field of education lacking relevant methodology. The literature study offers a better understanding of the design process and how it may be defined and viewed within an educational context. The interviews provide a more practical insight into the world of design education. The result shows that the design process as a didactical method theoretically offers both elements of critical thinking as well as direction and frames for students lacking aesthetic and artistic experience.

Diskussionsforumet Flashback Forum har med sin slogan ?Yttrandefrihet på riktigt!? etablerat sig som det forum på Internet där kontroversiella åsikter och provocerande material får fritt spelrum. Detta gör forumet till en tacksam forskningskontext när det gäller föreställningar om något så allmängiltigt som välfärdsverksamhet. Studiens syfte är att synliggöra de föreställningar om socialtjänsten och socialarbetare som finns på Flashback Forum, bilda en diskurs av dessa och sedan jämföra diskursen med andra diskurser kring samma fenomen. Flashback Forumdiskursen genomsyras av fyra teman; Misstro mot socialtjänsten och socialarbetare, Socialtjänsten och socialarbetares verksamhet, Socialtjänsten, socialarbetare och kön samt Tilltro till socialtjänsten och socialarbetare.

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

Floor signs in stores have become a more common phenomenon during past years. The problem is that the knowledge about these signs is limited and the actual effects are unknown. This lack of knowledge can have a negative impact on store performance and marketing efforts. The purpose of this paper is to examine the effects of floor signs on consumer attitude and behaviour. The study was conducted in two grocery stores, where the movement pattern of 39 501 customers was recorded over a four week period.

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.

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

I denna rapport utreds olika metoder för att kunna reglera vattennivån i vattenkraftverket Avesta Lillfors i Dalarna. Två kraftverk ligger endast 900 m uppströms och detta gör att svarstiderna blir korta och regleringen blir lätt nervös. Att använda sig av vattennivåreglering i ett kraftverk för-enklar dess styrning då anpassning till inflödet sker automatiskt.En flödestabell har tagits fram genom mätningar i turbinen, med hjälp av Winter-Kennedy-metoden. Denna tabell används för att kunna fram-koppla regulatorn och därmed dämpa stora variationer i inflödet. Dessu-tom har en modell av älven skapats och testats med en återkopplad PID-regulator.

In the global and rapidly changing society Environmental scanning is becoming a more and more important tool. Today it is not the availability of information that controls an organizations behavior, but the information that the organization chooses to absorb. This is the case for a multinational cooperation as well as for the local golf club. Swedish golf clubs have during the last 100 years had an amazing development and today there are almost 600 000 registered Swedish golf players. The development has however stopped and even declined some during the last couple of years.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Spelifiering har funnits genom historien, utan att det tidigare har definierats. Spår av användning av begreppet finns på Internet sedan 2004, men begreppet blev populärt först runt 2010. Spelifiering kan beskrivas som en process där det lånas komponenter och upplägg från spelvärlden som appliceras på verksamheter som traditionellt inte hör samman med spelande. I vår undersökning riktar vi in oss på kopplingen mellan spelifiering och lärande, alltså spelifierat lärande. Syftet med denna studie är att ur ett diskursanalytiskt perspektiv beskriva vad det är som kännetecknar spelifierat lärande.

The thesis investigates if it is possible to replace several pumpimpellers with one controllable pumpimpeller, with a economical and a manufacturing analisys aspect. The studied pumpimpeller is mounted on a midrange wastewaterpump, N3127MT.In the thesis a contemplated manufacturing process is evaluated for a concept that are supposed to act as a controllable pumpimpeller. The pumpimpeller are studied in a manufacturing and flow matter and are presented in the thesis.The manufacturing cost is also estimated, and this has been compared to the storage cost and other costs that the existing pumpimpeller generates.The thesis also shows that the concept has minor losses in cutting quality aswell as the effiency comparing to the existing pumpimpeller.The concept also raises the manufacturing cost and this increasing cost makes the presented concept to expensive to carry through.An investigation of the costs that the existing pumpimpeller produces has also been done, and this shows that there is not that much expenses to earn regarding to for example the storage cost. The storage cost includes information from Flygt?s central storagecenter in Lindas, Sweden and Metz, France, and also an inventory about the pumpimpellers located at Flygt?s different distributors worldwide.The thesis shows that a controllable pumpimpeller will generally increase the cost for the pumpimpeller and the performance of the pumpimpeller will decrease..

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work.
