Dexametasons effekt på trombocytaggregering och syreradikalproduktion

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Effektiv partiformning : analys och tillämpning på Uppåkra Mekaniska AB

This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process.

Har storleken någon betydelse? : En studie av den svenska aktiemarknadens reaktion på varsel om uppsägning av personal

Background: The reasons why this study is conducted is because of the latest recession in the global economy. The current recession has made a lot of companies more aware of its cost, and in order to fit the new harsher economic climate the companies has to be more cost efficient. In order to do so many companies choose to reduce their amount of employees. When this happens in a recession, most of the layoffs are an effect of reactive causes, such as lower incoming orders, and fewer customers. This leads to a problem for the companies that don?t know how these kinds of layoffs will affect the value of the company?s stock.

Konstruktion av kostnadseffektiv fläkt till härdningsugnar

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

Optimering av OTEC-system

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

Valet av Renegade och Paragon i Mass Effect : Undersökning av möjliga aspekter på valet att spela som ond eller god med fokus på spelarens subjektiva upplevelse

The purpose of the study was to examine possible aspects concerning the choice to play as good or evil with a focus on the players´ subjective experience. A form was constructed and the material was interpreted according to Interpretative Phenomenological Analysis (IPA). The games Mass Effect I and II were used as an example of the choice to play as good or evil since the choice between Renegade (evil) and Paragon (good) is present. The sample consisted of individuals who had played Mass Effect I and/or Mass Effect II and were over 18 years old. The end result concerning who played a Renegade or a Paragon came to be very uneven (15 out of 16 participants played a Paragon) which means that the result mostly relates to possible aspects concerning the choice to play a Paragon.

Betjäningskostnader i olika distributionskanaler: En fallstudie av ett svenskt bokförlag

In a time of economic turmoil and financial crisis profitability matters rise higher and higher on company agendas. Many companies are pressured to find profitability to avoid layoffs or even bankruptcy. Profitability essentially depends on the margin on the product or service sold and the costs associated with selling these products or services and hence these areas are of vital importance if companies are to improve profitability. Previous research has focused, for the most part, on product profitability while customer profitability has received less attention. This study is based on a case study of a Swedish publishing house and aims to investigate how the company?s Cost-to-Serve varies between its distribution channels.
