Geotermi i Ungern : Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.

Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.

Kön och genus relaterat till smärta i upplevelser, uttryck och behandling

One area of responsibility for a nurse is to alleviate suffering. Gender research has shown that there are differences between men and women. The aim of this literary study has been to elucidate men and women’s experience and expression of pain and to examine to what extent sex and gender influence which treatment the patient receive. The study is based on 21 scientific articles from the databases PubMed and Cinahl. The result shows that women experience and express more pain than men, postoperative and experimental. It is however not possible to draw any general conclusions in terms of the need for men and women to be treated in different ways.

Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

Inhibiting the IGF-1 receptor with the cyclolignan Picropodophyllin: an in vitro study of ovulation, implantation and receptivity in a mouse model

Picropodophyllin (PPP) is an analogue of the anti tumour lignan podophyllotoxin with the unique ability to selectively inhibit the receptor of Insulin like growth factor 1(IGF-1). IGF-1 is believed to play an important part in development of the endometrium facing implantation. With PPP treated mice, studies can be made to measure gene expression from tissue of both treated and untreated mice to compare the role of IGF-1 regarding ovulation, implantation and receptivity. The aim of this study was to analyze gene expression of some steroid hormone receptors and cytokines in ovaries from mice treated with PPP. In this study, seven mice were treated with PPP at different times and tissue was collected.

Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.

Optimering av interna trucktransporter vid Emhart Glass i Sundsvall

Resurssnål produktion är en teori om hur produktionsplanering i ett företag kan förbättras, vilket syftar till att öka effektiviteten och skapa en bättre arbetssituation för medarbetarna i företaget. Examensarbetets övergripande syfte har varit att med stöd i denna teori ta fram ett optimerat och verklighetstroget truckkörschema för dagens interna transporter vid Emhart Glass i Sundsvall. Målsättningen har varit att jämföra de interna transporterna med de behov som finns i företaget, att identifiera hur ofta transporter av tomma lastpallar sker samt att klar-göra om en dubbelpallshantering innebär tidsmässigt vinst. En kart-läggning av de interna transporterna och arbetsställenas behov av lastpallar har genomförts. Informationen från kartläggningen har implementerats i programmet Matlab, där en algoritm för beräkning av ett körschema har skapats som tar hänsyn till dagens tidshantering av lastpallar och sannolikheten att truckförarna lastar av och på lastpallar vid olika arbetsställen.

Att lära sig relationskompetens och ledarkompetens : En studie av grundlärarutbildningens utbildningsplaner och kursplaner när det gäller relationskompetens och ledarkompetens

The main purpose of this essay is to investigate the legal position for employers concerning protection against what employees can express about one?s employer in social media.It may regard dissatisfaction concerning employment, tort or so-called whistleblowing. The spread through social media may be comprehensive and thus cause more damage to the employer.Employees within the public sector as well as in the private are protected by the liberty of speech, which is constitutional, even the protection of sources or the right to criticize can offer some protection. This gives the employees the possibility to widely express themselves in private social media as long as it can?t be classified as a violation, which per se is very rare.However, certain differences between the both sectors will be pointed out.There are still no constitutional rights regarding social media, but a grey area has emerged concerning the legal position.

Finansiärer ur ett hållbarhetsperspektiv : En aktörsstudie av Europeiska Investeringsbanken, Nordiska Investeringsbanken och Svensk Exportkredit

 Today a major part of the energy produced steams from fossil fuels, finite resources, and a change towards an energy sector based on renewable energy is necessary. Sweden is one of the leading countries with regards to investments in renewable energy but most other countries have a long way to go. This makes it interesting in developing renewable energy projects in new markets in countries like Poland where still a lot of fossil fuel is used. Large infrastructure development projects are very costly and therefore external investors needs to be involved. The investors play an important role in changing the usage of fossil fuels towards renewable energy sources.

Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :

The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.

Adaptiv temperaturreglering av bostadshus

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Träbroar för järnvägstrafik

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

VD-karusellen : En eventstudie om en VD-avgångs påverkan på marknaden

The goal of this study is to examine how the market reacts when information about the exchange of a CEO becomes public. It also examines factors such as gender and whether the departure was voluntary or not, discerning if the market behaves differently concerning any of these aspects.To achieve this, the study was performed using an event study. The selection consisted of 48 companies on the Stockholm Stock Exchange, who had during the years 2005 to 2008 underwent a change in leading management. These units were submitted to hypothesis tests, to determine if an abnormal return was attained during the event window. The tests were performed on the units as a whole, and divided up after gender and whether the departure was voluntary or not.The results of the study show no statistically significant abnormal return caused by the announcement of a CEO exchange.
