The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.

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.

Hematology-instruments that analyze blood cells can at specific cases be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

Due to the wide usage of different databases administrated by the Swedish government to keep control over its citizen?s the issue has arisen concerning if this information is subject for other purposes then originally acknowledged. Executives induced in recruitment for labour has over the years extended their need for information accumulated by these systems. Especially data from the criminal records registry are now being used as a normal step in the employment process among a vastly growing spectrum of enterprises and businesses all over the country. This thesis aims to illuminate the subject by grasp to what extent the described behaviour can be considered legally accepted according to the law or if these actions are inflicting with the foundational juridical principles that has to be ensured by the Swedish government due to our constitutional law.A strict jurisprudential method has been applied throughout the entire thesis to ensure the reliability of the results. The diversity of sources has gently been put together to assure the overall quality.

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Agency theory describes the conflict of interest between the principal (stockholders) and the agent (CEO). Aligning the incentives of executives with those of the owners is the most direct way to mitigate the agency problem. If there is no meaningful link between CEO compensation and company performance, it is doubtful that the large sums of assets in public corporations are being managed efficiently. In theory the solution is simple reward the CEO when shareholders wealth increases. The purpose of this paper is to investigate if there is a relationship between company performance and CEO compensation among Swedish companies, in materials and information technology industry.

Patienter med nedsatt kommunikationsförmåga har begränsade möjligheter till att förmedla sin smärtupplevelse. Sjuksköterskan har till uppgift att bedöma patientens smärta vilket kan vara oerhört komplext. Syftet med denna litteraturstudie var att  belysa  bedömning av smärta hos vuxna patienter med nedsatt kommunikationsförmåga. Litteraturstudiens resultat grundades på 15 kvalitativa och kvantitativa vetenskapliga artiklar som kvalitetsgranskades och bearbetades. Analysen av dessa artiklar resulterade i två teman: smärtbedömning av vuxna patienter med nedsatt kommunikationsförmåga och smärtuttryck hos vuxna patienter med nedsatt kommunikationsförmåga.

Smärta förekommer inom all sjukvård och är ett komplext problem, speciellt inom intensiv- och postoperativ vård då patienten ofta inte själv kan beskriva sin smärta eftersom patienten ofta är medvetslös eller är sederad. För att bedöma smärta finns olika verktyg, men för de som inte själv kan beskriva sin smärta är detta en svårighet. Syftet med studien var att undersöka reliabilitet och validitet på smärtbedömningsformulär inom intensiv- och postoperativ vård. Metoden vi använde oss av var en kvantitativ litteraturstudie för att besvara vårt syfte. Databaser som använts är CINAHL, PubMed och SweMed+, med sökorden nurse*, pain scale, pain assessment, pain measurement, questionnaire, postoperative och intenisive care.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.

Nature´s healing capacity is well known and is today an important asset in the protection against stress. Noise problems in cities and it´s green spaces are increasing which in turn provokes stress and in the long term can lead to cardiovascular diseases. To promote people?s health it is important that natural environments have good soundscapes, research show that visiting natural surroundings and listening to sounds of nature promote rehabilitation and relief stress. The purpose of this essay is to determine the value of rehabilitation in forests in Carlshem and Röbäck.

Bakgrund: svårigheter uppstår med kommunikationen mellan patient och sjuksköterskan vid insjuknande i Alzheimers sjukdom vilket leder till hinder i smärtbedömning av personer med Alzheimers sjukdom jämfört med bedömningen avpersoner utan kognitiv nedsättning. Syfte: syftet med litteraturstudien var att belysa vikten av korrekt smärtbedömning hos patienter med Alzheimers sjukdom. Metod: studien var en litteraturstudie, 12 artiklar samtliga kvantitativa som svarade mot studiens syfte har granskats och analyserats. Resultat och konklusion: bedömning av smärta hos patienter med Alzheimers sjukdom är komplex, slutsatsen är tvetydig då resultatet visar dels att personer med Alzheimers sjukdom har mer smärta respektive mindre smärta än personer utan kognitiv nedsättning. Bedömningsinstrumenten som undersöktes i studien visade sig vara relevanta men ansvar och kunskap från sjukvårdspersonalen som använder instrumentet var ett krav för att kunna utesluta felkällor av tecken på smärta så som onormala rörelser, beteende och ljud.
