"Ettan" som kom först : En kvantitativ innehållsanalys av hur en studenttidnings förstasida förändrats genom tiderna
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. .
Fattar du vad de säger? : En begriplighetsanalytisk jämförelse mellan Ekot och P3 Nyheter
In this study we compare Ekot with P3 Nyheter with a comprehension analytical perspective. The more traditional radio news program Ekot differs from the younger P3 Nyheter in a lot of aspects. One of them is that P3 Nyheter?s primary target group is young people between the ages of 20 to 34. Because of this, P3 Nyheter aim to make their news as adjusted to their young audience as possible.
Den gyllene medelvägen mellan värdegrundernas frihet och styrkortets disciplin : En studie av olika ledningsnivåers syn på balansen mellan ledning och styrning vid Sveriges Radio
Bakgrund: Förhållandet mellan frihet och disciplin, för att använda Foucaults (1987) ord, är en ständig fråga för människan. I olika tider har balansen mellan frihet och disciplin sett olika ut. I en organisation kan begreppen översättas till ledning respektive styrning. Bland dagens mest populära organisationsrecept märks värdegrunder, som svarar mot begreppet ledning, och det balanserade styrkortet, som är ett verktyg för styrning. Syfte: Att öka förståelse för hur tre olika ledningsnivåer inom Sveriges Radio ser på förhållandet mellan värdegrunder och det balanserade styrkortet, hur de förmedlar denna syn på förhållandet och varför de har denna syn. Avgränsningar: Den här studien handlar inte om hur förhållandet mellan värdegrunder och det balanserade styrkortet faktiskt ser ut vid Sveriges Radio eller hur medarbetarna ser på förhållandet; inte heller handlar den om hur väl Sveriges Radios styrningssystem fungerar. Metod: På de tre studerade ledningsnivåerna har på varje nivå först en deltagande observation genomförts. Därefter har en nyckelperson på varje nivå intervjuats utifrån metoderna om kvalitativa forskningsintervjuer med semistrukturerad form.
Bulleremissioner från vertikalaxlade vindkraftverk
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..
Sjukdomsfrekvens och utslagningsorsaker hos kor med 12 respektive 15 månaders kalvningsintervall
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.
Är Grönt Skönt?: En studie om hur effekten av grön marknadsföring påverkas av förekomsten av miljöargument inom produktkategorin
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.
Risk och osäkerhet vid inträde på den svenska apoteksmarknaden: En studie om nya aktörer på en marknad under omreglering
The Swedish pharmacy market will be re-regulated in July 2009 which will present private actors with an opportunity to enter the market. Several risks and uncertainties are associated with such an entry. The purpose of this thesis is to increase the understanding of identification and management of risks and uncertainties associated with entering the Swedish pharmacy market. We also intend to investigate similarities and differences in risk identification and risk management as well as create an understanding of the underlying reasons for these similarities and differences. Three companies interested in entering the market have been interviewed and the interviews were conducted with an open approach to avoid influencing the companies? answers.
Effekten av ett probiotikum i en besättning med hög incidens spädgrisdiarré
Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
- Jag är den jag var då - det är förutsättningarna som har förändrats? - en postkolonial feministisk studie utav invandrarkvinnors berättelser om identitetskonstruktion och förändring
Postcolonial feminist theory says that ones identity is constructed by severalfactor, not only gender but even culture, ethnicity and class imbedded in the socialcontext. This paper examines what happens to women's identities if the socialcontext changes. Does an identity shift occur? By interviewing five women fromBosnia-Herzegovina I try to understand the affects migration has on women?sidentity. Postcolonial feminist theory says that our identities are constantlychanging, as their constructing factors.
Internetbaserade insamling och behandling av data
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.
Aktiekursförändringar och sökfrekvens på internet
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..
Utvärdering av felmeddelande i eMM Software Version 00-06 till SysmexXE-5000
Sysmex XE-5000 är en automatiserad cellräknare som utför mätningar enligt olika
mätprinciper, de två som tillämpats i projektet är RF/DC(Radio Frequency/Direct
Current) samt Flödescytometri med halvledarlaser. RF/DC bygger på förändringar
i radiofrekventa resistansen och likspänningsresistansen. Förändringar i den
radiofrekventa resistansen (RF) ger information om densiteten i cellernas inre
(exempelvis kärnans storlek) och förändringar i likspänningsresistensen (DC) ger
information om blodcellernas storlek. Flödescytometri definierar ett mått på
cellers fysiologiska och kemiska egenskaper. Detektion av cellerna sker genom att
de bestrålas med en laserstråle samtidigt som de passerar en och en i instrumentet.
Informationen som fås ut från flödescytometri inkluderar spritt ljus och
fluorescens.
Mätsystem för effektförluster i en högfrekvenstransformator
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%.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige
Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
