SAMMANFATTNING Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).

The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .

The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

Syftet med denna uppsats är att, på Företag X, undersöka arbetsledarnas upplevelse av kommunikationen mellan arbetsledarna och medarbetarna samt att undersöka hur arbetsledarna upplever att medarbetarna motiveras och hur arbetsledarna motiverar sig själva.Faktorer som undersöks mer ingående är arbetsledarnas upplevelse av:hur uppåtriktad kommunikation främjasatt kommunicera impopulära budskapeventuella hinder i kommunikationenickeverbal kommunikationhur feedback fungeraratt skapa mål för motivationövriga sätt att skapa motivationarbetsledarnas sätt att motivera sig självaFrågeställningarna är följande:Hur upplever arbetsledarna kommunikationen mellan arbetsledarna och medarbetarna?Vilka eventuella hinder upplever arbetsledarna för kommunikationen?Hur upplever arbetsledarna att medarbetarna motiveras?Hur motiverar arbetsledarna sig själva?Undersökningen är kvalitativ och intervjuer har använts för att samla in empiri. Sex intervjuer har genomförts med arbetsledare på Företag X.Vårt resultat och analys visar att arbetsledarna beskriver att de har för avsikt att främja uppåtriktad kommunikation för att minska ryktesspridning och ´gnäll´/klagomål. De beskriver att de informerar impopulära budskap på ett genomtänkt sätt genom att informera tydligt i mindre grupper. Arbetsledarna beskriver vissa hinder i kommunikationen så som att de inte utbildats i kommunikation och attityd både deras egen och medarbetarnas.

The incidence of many of the most common diseases in dairy cattle has been proven to be highest during the time closest to calving. It is possible that the current breeding strategy with 12 month calving intervals increases the risk for disease in dairy cattle, which is problematic concerning both animal welfare and for economic reasons. The economic incentives behind a calving interval of 12 to 13 months have mainly been based on milk- and feed- costs and no costs due to diseases or fertility disturbances have been included.The aim of this study was to see if a lengthening of the calving interval would result in lower disease frequency. The hypothesis is that cows with a planned calving interval of 15 months have a lower disease incidence than cows with a calving interval of 12 months due to less number of calvings. Therefore the difference in disease frequency should be larger when compared over a long period of time, such as over lifetime, since cows with a longer calving interval experience fewer calvings.The study was performed between August 17th, 1994, and January 24th, 2007.

Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.

This project practise methods used in the interaction design discipline to develop a concept related to the Swedish Guinness World Records Magazine. This project is a challenge to accommodate both the users? and client?s needs. We focus on interaction and the experience, which is acquired through the use itself, and how to connect it to a theme from a client. The aim of this project is to create a meeting place for children where they can interact with technology.

This essay aims at understanding the experience of the use of ayahuasca, and similarities and differences between interview protocols and socio-cultural identities. The work is based on field studies conducted in the Peruvian Andes, in the village of Pisac September to November 2009. What has emerged is that the experience does not seem to be dependent on cultural manifestations as much as it is dependent on general human cognition. Theories have been applied on an empirical phenomenological descriptive study. Various brain activities, along with mental mechanisms contribute to a deeper understanding of the findings in the descriptive analysis.It seems that the cultural differences, which I have classed as typological in the phenomenological study, mostly are expressions of meaning for the informants.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

SUMMARY By altering the longitudinal slopes of the cubicle floors the drainage could be improved. If the altered slopes also position the cows further back in the cubicles the effect could be cleaner lying surfaces. In result this would lead to lower labour requirements, cleaner cows, cleaner udders and a minimization of the risks of mastitis. However, if the altered slopes lead to that the cows position themselves more diagonally in the cubicles the positive effects could be reduced. The altered slopes could even have a negative influence on the animals? natural lying behaviour.

Syftet med studien är att undersöka hur lärare uppfattar bedömning i matematik och hur de tolkar begreppet bedömning för lärande. Vidare undersöks huruvida bedömning för lärande kan användas inom ämnet matematik på gymnasiet och hur detta påverkar elevers lärprocess. Resultatet grundar sig på intervjuer med matematiklärare på gymnasiet, och pekar på att lärare har en diffus uppfattning kring begreppet bedömning för lärande. Vidare visar resultatet att bedömning för lärande används, både medvetet och omedvetet, i olika former inom matematikundervisningen. Framförallt är det feedback och konkretisering av mål som är återkommande och framstående komponenter i förhållande till bedömning för lärande.
