Reagera och agera: Styrka och snabbhet i den manuella responsen för emotionella stimuli

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Varuutstyrslar, produktens form som kännetecken.

In the expansion rate of the national as well as the international market, the importance of trademark has been given a central matter. The definition of what can be considered a trademark has been widened. Today?s trademark law defines a trademark as something that can be graphically reproduced. Trademarks can there for contain names, words, numbers, letters or the shape of the goods itself or the packaging.

The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Reporäntan och Sveriges banker : En eventstudie om reporäntan och dess förändringars påverkan på svenska bankers aktiekurser

Syfte: Uppsatsen syfte är att klargöra och analysera reporäntans ränteförändringars påverkan på aktiekurserna för samtliga svenska banker i large cap på Stockholmsbörsen.Metod: Kvantitativa händelsestudier har gjorts med deduktiv forskningsansats på fyra företag, samtliga noterade på Stockholmsbörsen. Den onormala avkastningen för de undersökta aktiekurserna har beräknats en dag före till en dag efter samtliga realiseringar av reporänteförändringar som skett mellan åren 2004 till 2015. Teori: Den teoretiska referensramen för studien består av den effektiva marknadshypotesen och överreaktionshypotesen.Slutsatser: Studien har påvisat att det råder signifikant samband mellan ränteförändringar och de studerade aktiernas avkastning vid realisering av ränteförändringarna..

Kompetensbegreppet i kommunal verksamhet : En kritisk diskursanalys

Large retirement numbers and fierce competition of available labour, results in municipalities have to be more attractive as an employer. One way for the municipalities to fulfil their staffing requirement is partly to increase their recruitment efforts, and partly to educate their existing employees. Discussions about the supply of competence are therefore pressing within municipal activity. The aim of the study was to investigate how the concept of competence is used within a municipal administration. The method that has been used is Norman Fairclough?s critical discourse analysis, a method that allows multi dimensional analysis.

Fordonsgas från deponier : en potentialstudie i Biogas Öst-regionen

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.

Lättläst eller inte? : En läromedelsanalys av lättlästa läroböcker, inom ämnet svenska, anpassade för elever med läs- och skrivsvårigheter

The demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.

Aspekter på folkbibliotekens Internetsatsningar verksamheter, intentioner, regleringar

The aim of this thesis is to study different aspects of the public libraries' investment in public access computers connected to the Internet. What level of accessibility can be found at the surveyed libraries concerning the number of computers open to the public, as well as chat and email services? What activities have been taking place with the computers in focus, and what have the goals of these activities been? Is there any control of content, and what aspects of the Internet are, if that is the case, subject to censorship. And how do the governmental policies relate to the surveyed libraries' intentions and activities regarding the Internet? In order to answer these questions, each main library in the 42 largest towns of Sweden was surveyed response rate: 100 %.

Meticillinresistenta Staphylococcus aureus hos häst : zoonotisk smittspridning, riskfaktorer och förebyggande åtgärder

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Managementska låneord bland låneböckerna: Om bibliotekariers attityder till marknadsmetaforer på biblioteket

Over the last decades, language in the public sector has changed due to influence from New public management. In this thesis, I seek to investigate librarians? attitudes towards a more businesslike way of speaking about libraries, referred to here as management-speak. For this purpose, I?ve used a modified version of the matched guise technique.
