Dömd eller bedömd? : en studie om bedömning av de nationella proven ur ett lärarperspektiv
The aim of this study was to analyze the assessment of the national tests seen from the teacher?s perspective. The national tests are performed in the Swedish school, classes 3, 5, 9, and the upper secondary school (gymnasiet). There has been an ongoing discussion regarding assessment and grading for a long time and it is of high interest now more than ever. The last control assessment done in 2009 by the department of school inspections on the order of the Swedish government, showed big differences between the assessments done by the teachers, and the assessments completed by the department of school inspections.
Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.
Kryogen uppgradering av biogas med kyla från värmedriven absorptionskylmaskin
Detta är ett examensarbete som genomförts hos Göteborg Energi AB och syftar till att utreda omkryogen uppgradering av biogas med fördel kan ske genom att producera nödvändig kyla medvärmedriven absorptionskylmaskin. Göteborg Energi är en av tre parter som tillsammans ska bygga enbiogasanläggning i Lidköping som ska vara i drift 2010. Anläggningen ska producera 30 GWhflytande biogas per år.Arbetet utreder om det är fördelaktigt ur ekonomiskt, energimässigt och miljömässigt perspektiv attuppgradera biogas med kryogen teknik med värmeproducerad kyla. En jämförelse görs först medkryogen teknik där kylan är producerad med el och sen med andra uppgraderingstekniker. Som stödhar två olika processimuleringsprogram används, Hysys och DESIGN II.Resultatet visar att energianvändningen ökar då värmedriven kyla används i jämförelse med kylaproducerad med el.
Kundlojalitet på den elektroniska marknaden : strategier för att skapa lojala e-handelskunder
In recent years e-commerce has experienced a big increase in usage. Internet however, cannot offer the same level of personal contact as traditional shops can.E-commerce is characterized by impersonal and standardized web shops that do not stimulate any emotional connection between the customer and the company. Without this personal contact with the customer the possibilities for the company to stimulate loyalty decreases. Loyalty however, is as important in e-commerce as it is in traditional commerce. The authors of this paper chose the following problem for the study:What marketing strategies are fortunate for e-commerce companies to use to create loyal customers?To research this subject the authors saw it fit to combine qualitative and quantitative research methods.
Omvårdnadsinterventioner för oral mucosit i samband med strålbehandling mot huvud- och halscancer
Patienter som erhåller strålbehandling mot huvud- och halscancer drabbas i hög utsträckning av behandlingsrelaterade biverkningar. Oral mucosit, skada på munhålans slemhinna, är vanligt förekommande och kan påverka patientens grad av livskvalitet. Sjukvårdspersonal undersöker inte regelbundet munhålan och det kan därför dröja innan tecken på skada uppenbaras. Syftet med denna uppsats var att beskriva omvårdnadsinterventioner vid oral mucosit i samband med strålbehandling mot huvud- och halscancer. Vidare att beskriva om standardisering av omvårdnaden kan lindra behandlingsrelaterad oral mucosit.
Vätskekopplade värme- och kylåtervinningssystem Utveckling av ett verktyg för energiberäkningar
According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.
Att bygga en stamdatabas för gotländsk tall
Today's Swedish large-scale forestry uses almost exclusively computer-aided bucking. It allows the harvester computer, using an optimisation price list (steering price list), to maximize the value of each tree. The optimisation price list can be adjusted so that the industry gets the raw material it demands from the forest.
There are various simulation programs that can be used when constructing a optimisation price list. The simulation program merchandise a database of stem shapes using a given price list and mimics a harvester's work. To get the demanded raw material for the industry it is important to use a well-adjusted optimisation price list.
Vad blir till hjälp? - en studie om hjälpande faktorer i sjukhuskuratorers arbete SW2226/SW2227,

Vårdcentralschefers perspektiv på distriktssköterskors förskrivningsrätt
Background: In 1994 came the general prescription law in force for the district nurses with specific training in pharmacology and pathology in Sweden. According to The National Board of Health and Welfare from 2004 follow-up of the use of the prescription law revealed that nearly half of the district nurses used their prescription once a week. According to previous research the district nurses and patients were positive to the district nurses administration of prescriptions. Doctors, contrariwise, were not as favorable to the district nurses administration of prescriptions. The responsibility of the heads of the health centers is to promote the district nurses to prescribe and make sure that it works in a satisfactory manner.
Avlivning av sällskapsdjur, utförd av annan än veterinär : ett djurskyddsproblem?
We know that more than 2/3 of insured dogs in Sweden are put to death by a veterinarian, which means that almost one third are killed in trauma, lost or die in some other way. An unknown number of these are killed by their owner with no veterinarian involved. This graduate thesis contains a specification of the laws that control euthanasia of dogs and cats in Sweden, and the veterinary medical basics on how to perform euthanasia. The objective is also to give understanding on how pet owners choose to put their animal to death and why, and to discuss whether that is an animal welfare problem.
It is legal to kill dogs and cats by shooting, using a sporting gun, provided that it is done according to laws and regulations.

Svenska livsmedel - varför? : restaurangers, grossisters och offentlig upphandlares inställning till livsmedel från Sverige
The background of this research is that Swedish food products have hard to compete at the home market, depending on imported food products that increase more and more for every year that pass by. The ethic values LRF associate with Swedish food products, many customers have hard to put in relation with condition of foreign agriculture.
Most customers today inquire high quality, safety and convenience in the food which they are eating. The source of their food seems to have less meaning. Many restaurants and bigger households appreciate Swedish food products and wants to buy them but price differences against foreign wares are to high.
We have done oral interviews with wholesale dealers, restaurants, public purchasers and with different market organisations, there we have discussed buying strategies, the way they see the primary producer, the conscious of guests, choice and attitudes to Swedish and foreign products, distribution of power in the food market chain and to what position and suspension, they want the ranks of suppliers to have.
The result shows the share of imported wares within restaurants and bigger households are at a high level and will continuing increasing. Within these sectors the final consumer in many cases put less effort in the origin of the raw source of food.
Visuell informationshantering i tunga fordon : Behovsanalys och förslag till förbättringsåtgärder
The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.
