Recensioner och Nätgemenskapskvalitet : En studie om metod för betygsättning i spelrecensioner och dess inverkan på produktengagemang och nätgemenskapskvalitet.

The goal of this essay was to study if the way gaming review sites presented their review evaluation has any influences the level of product involvement in the users it attracts. The assumption we did during the essay was that there was a connection between user?s level of product involvement and the quality of the community. To test this assumption we started out by performing observations on the comment sections in three gaming news sites which varied in their method for evaluating games. The result of these observations showed a significantly higher community quality in one of the websites.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Mozzarella : En djupdykning i ostmassan

Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.

Hälsoekonomiska utvärderingar - En litteraturöversikt om använding av konstnadseffektivitetsanalys inom folkhälsoområdet

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

Lingvistik och användbarhet i sökmotorer

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.

OLED : Evaluation and clarification of the new Organic Light Emitting Display technology

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Triage - hälsoekonomi : resursallokering och kostnadsberäkning för olika proriteringsnivåer inom akutsjukvård

When a person arrives at the emergency ward at the Uppsala University Hospital with his or her symptoms he or she explains the problems and then a priority process starts. The staff evaluate at which emergency level the patient is located in a model called Triage. The Triage model helps to decide the priority need and is based upon templates which point out in which of the 5 categories a patient is to be placed, to eliminate any future risk regarding his or her health. A lower triage level means lower priority but implies better health when the evaluation takes place. To obtain optimal effect of the Triage model the evaluation of symptoms must be reproducible so that patients with the same symptoms are placed at the same triage level regardless of whom among the staff conducts the evaluation. The purpose of the study was to see if the resources are allocated based on priority level of the patients.

Varför sociala medier? : En undersökning av folkbibliotekens arbete med extern marknadsföring.

In our thesis we investigate how public libraries are working with external marketing via social media. The study aims to found out what the reasons are and how public libraries are using social media to market themselves. Furthermore, how they evaluate the success of these marketing efforts. We limit ourselves to public libraries and its staff. The theory that we have chosen to use to analyze our data is the marketing mix of the 4 P'S (product, place, price and promotion), but we have replaced the ?price? with ?staff? because ?staff? is more relevant for library management.

En för alla - Alla för en? : Krissamverkan och intern informationssamordning mellan nätverkande myndigheter

The purpose of this thesis is to study the context that affects crisis communication through an organizational perspective. It also tries to identify factors of success and difficulties when it comes to coordinating information between governmental organizations during a crisis. Carried out as a case study of the Swedish governmental network Krissamverkan Kronoberg, the method used are source analysis and qualitative interviews with members from different organizations in the network. The results have been analyzed through Organization theory, Network theory and theory in Crisis Communication. The context that effects governmental organizations ability to cooperate during a society crisis is characterized by knowledge, understanding, utility and willingness. In addition to this a successful coordination of information should be based on resources, competence and continuity. The main problems when it comes to cooperating and coordinating during a crisis situation lies in what we would like to call organizational egoism, existential uncertainty and defensive behavior. .

Vad påverkar HIV i Sydafrika? : En teoretisk och empirisk analys av Sydafrikas provinser 2008

What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.
