AbstractAim of the study: Aim of the study was to investigate whether there were any connections in time between different parts of care in patients with cardiac arrest and hypothermia treatment and cognitive and physical function six months after cardiac arrest and to investigate neurological outcome related to primary registered cardiac arrest rhythm after six months and if there were any changes in cognitive and physical functions as well as self-related health between discharge from hospital and six months after cardiac arrest.Method: The study included 39 patients admitted to three Swedish hospitals between 2008-2011. Cognitive and physical function was evaluated with Cerebral Performance Cathegory, CPC completed with Mini Mental State Examination, MMSE for cognitive function and Bartels Index, BI for physical function and Euroqol-VAS for evaluating the self-related health.Result:  A significant connection was shown between time to start hypothermia treatment and BI, patients with longer time showed improved physical function after six months.Majority of the participants (66,7 %) had Ventricular fibrillation/Ventricular tachycardia, VF /VT, as primary registered cardiac arrest rhythm and in this group CPC and BI was significant better compared with the asystole /Pulsless Electrical Aktivity, PEA group.CPC, MMSE, BI and Euroqol-VAS were all improved over time.Conclusion: Participants with VF /VT as primary registered cardias arrest rhythm had significant better cognitive and physical function 6 months after hypothermia-treated cardiac arrest compared with participants with asystole/PEA as primary registered rhythm. This shows the importance of access to defibrillators in public places in the society and in hospitals and optimal education of lay people and medical staff. Cognitive and physical function and self-rated health improves over time, which might be a very important reason to convey patients, relatives and medical staff to continue cognitive and physical rehabilitation. Keywords: Cardiac arrest, hypothermia, cognitive and physical function, wellbeeing.

To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

The main purpose of this essay is to investigate if Latvia´s pattern of trade has become more similar to the mature market economies, after Latvia´s independence 1991.Today, the intra-industry trade (IIT) dominates the trade of mature market economies. One of the pioneers of intra-industrial trade is Paul Krugman, who was the first to emphasize the importance "of scale and consumers' desire for variety" in explaining the basis for modern commerce. Customers get more variety and usually cheaper goods when the market gets bigger. I mainly use the modern trade theories to explain the trade pattern in Latvia. To measure how Latvia has developed its intra-industry trade, and thereby is approaching the mature market economies´ trade pattern, I use the Grubel-Lloyd index (GL-index).

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

Perifera nervskador uppkommer oftast till följd av trauma mot nervstrukturerna. Karpaltunnelsyndrom innebär att det har blivit en skada på n. medianus till följd av tryck mot nerven. Symtom som uppkommer vid skadan är stickningar, domningar och smärta i nervens utbredningsområde och patienterna vaknar ofta på nätterna till följd av parestesier i den drabbade handen. Tarsaltunnelsyndrom liknar karpaltunnelsyndrom och innebär att patienterna drabbas av stickningar och domningar i n.
