Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3
A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.
Pedagogistans pedagogiska ledarskap
The pedagogista is a new professional role in Swedish preschools. Some people question the role, which originates from Italy, since it is believed to carry out a pedagogical leadership that belongs to the head of the preschool according to the curriculum and the Education Act. Consequently, there is cause for examining what pedagogical leadership means in an organization with a pedagogista. However, re- search has shown the success of distributed leadership within schools. Hence, it ?s interesting to find out whether the pedagogical leadership of the pedagogista could be understood as distributed leadership and what that would implicate.The purpose of this thesis is to explain and understand the pedagogical leadership of the pedagogista.
Gummitryck eller Photoshop : Kan gummitryck motiveras om det går att få samma resultat digitalt?
The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.
Elever med läs- och skrivsvårigheter : En kvalitativ studie om metoder och åtgärder i klassrummet
Individual adaption to the student´s needs is a recurring main theme in the new Swedish curriculum (Lgr11). The purpose of this qualitative study is to examine how teachers work with individual adjustment for students with reading and writing difficulties. The study was based on five questions;In what way do teachers organize their teaching in the classroom individually for students with reading and writing difficulties?What methods do they use for student´s with reading and writing difficulties?What difficulties do they encounter in their teaching?How do the teachers reason to curriculum goals regarding individual adaptions?How do they think about their own knowledge regarding reading- and writing difficulties and dyslexia?The method for my study was qualitative interviews. Five teachers were interviewed in semi-structured interviews.
Värderingsskillnader mellan amerikanska och svenska bioteknikbolag
Background: Companies with a high level of research, such as biotech companies, rarely generates any profit in the begining. Mostly their history is short and their pipelines usually consists of one or a few products only. Significant for the line of business is also a future very uncertain, where relevant objects of comparison are few. Altogether the facts above makes valuation of Biotech companies difficult. Swedish Biotech companies, compared to their american competitors, seem to be of relatively low value.

Alphonse Mucha och art nouveau : En undersökning om influenser hos samtida illustratörer
Den här uppsatsen syftar till att göra en kartläggning av den svenska novellgenren för att konkretisera den så kallade novellboomen som uppstod under 1990-talets mitt och dess anledningar. Vidare undersöks den amerikanske författaren Raymond Carvers betydelse för novellboomen, för att konkretisera och utreda om det finns någon substans i påståendet om hans påverkan på den svenska novellistiken, eller om det istället handlar om en kritikerbaserad genretillskrivning. Detta resonemang förs utifrån de berörda författarna, vissa litteraturkritiker och några bokförlags ståndpunkter i frågan. För att kunna se om hypotesen stämmer eller inte har en modell eller ett mönster med de mest generella dragen för Raymond Carvers novellistik sammanställts. Dessa generella mönster har sedan jämförts med fyra novellister som debuterade under ovan nämnda period, för att se vilka likheter dessa texter och novellister uppvisar med Carvers karakteristiska drag.
Kreativt tänkande, psykologiskt geografiskt avstånd och mätmetoder : - Ett experiment bland universitetsstudenter
The purpose of this thesis is to study how Malaysia Airlines communicated during the two largest crises of 2014. Key questions to be answered are: Did organizational hypocrisy occur? If yes, in what way? Which communication strategies were used? Did the company mediate an unequivocal message and how was the information framed? Did any aggravating factors, which worsened the organization?s reputation, appear? How did Malaysia Airlines manage possible rumours? Was the word contact used as a keyword? The method of choice is a quantitative content analysis and the material consists of 20 different analysis units. These analysis units were collected from social media and Malaysia Airlines website. The quantitative content analysis is based on the theory Situational Crisis Communication Theory, taken from PR, Strategy and Application, Managing Influence, by W.
Att ta cykeln till arbetet : en studie av Stockholms satsning på cykelpendlare i jämförelse med Köpenhamn och London
The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.

Potatisen ur ett handelsperspektiv :
ABSTRACT
The potato has had an important role in the Swedish dietary customs for quite some
time. However, during the last forty years, consumption has decreased from 87
kg/year and person to 46 kg/year and person. Other products such as pasta, rice and
bulgur are competing with the potato. Many of the competitors have been developed
and refined while the potato has not changed much. The potato is still a bulk product
while competing products have been differentiated.
Stakeholders within the potato market has realized that something has to be done and
today there are a number of organizations and networks that all actively work to
preserve the Swedish agriculture and specifically the potato as a product.
The purpose with this essay is to examine how store managers in the Swedish grocery
stores view the handling of the potato in the store, the quality and packaging,
marketing and future consumption.
Dark Side of Wonderland - en kort 2D-animation med syfte att väcka intresse för en online serietidning
My objective for this project was to create a short but thrilling 2D-animation
intended as promotion for an online comic book. The purpose of the project was
to learn more about animation and graphics, to further my artistic skills and
to learn how to work in Adobe After Effects. I also wanted to learn more about
scheduling, project methods and how to handle stress. During the ten weeks of
the project I have created the story, the storyboard, the character design, the
backgrounds and the animation. The voice over was recorded with the help of a
fellow student who also made the music and the sound effects.
Riskbaserat provtagningsprogram för mikroorganismer i Gäddviks vattentäkt
Risk-based sampling program of microorganisms in the water source in northern SwedenAfter several disease outbreaks caused by parasites in the drinking water during the last years, it is more essential than ever to insure that the water supply companies have enough barriers to counteract the presence of microorganisms in the outgoing water. It is also discussed whether climate changes such as increased precipitation can have a connection to the increased cases of parasites in water sources. The water source at Gäddvik is Luleå municipality?s largest and provides drinking water to 64 500 of Luleå?s 74 000 inhabitants. The investigation of microorganisms in the water source, especially in the Lule River has not been as prioritized as the sampling of chemical parameters.
Glycerol to dairy calves : effects on intestinal health and fluid balance
The bacterium Lactobacillus reuteri, which natural habitat is in the intestine of mammals and birds, uses glycerol as a substrate for production of the antimicrobial compound reuterin. Glycerol has been shown to decrease the number of Escherichia coli in human feces and it is believed to be due to in situ production of reuterin. E. coli belongs to the large family of Enterobacteriaceae, naturally occurring in the intestine, and pathogenic strains of E. coli have been shown to be one of several bacteria causing diarrhoea in calves.
