Alternativ splicing: en process som medför att flera olika mRNA-transkript bildas från individuella gener
This review article presents the splicing process during messenger RNA maturation and how it is regulated by different Cis-regulatory RNA-sequence elements and splicing factors. A more detailed description of the process alternative splicing and its importance to the function of genes from the model organism Arabidopsis thaliana is also given. A single eukaryotic gene can by the process alternative splicing (AS) give rise to a number of functionally mature mRNA-molecules, which in turn encodes for structurally and/or functionally different proteins. During the course of evolution, the process alternative splicing has thus shown to be effective in increasing transcriptome and proteome diversity of most eukaryotic organisms. This suggests therefore that the dominant theory in molecular biology, a gene encodes for a protein, needs to be corrected.
Har analytikernas roll på aktiemarknaden blivit mindre relevant: En studie av analytikernas påverkan på aktiers avkastning
The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.
Probiotika som prevention mot urogenitala sjukdomar
About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..
Styrr?ntans olika effekt p? bostadsmarknaden - En komparativ studie om hur bostadspriserna p?verkas olika av r?ntef?r?ndringar i stora och sm? st?der.
This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.
Styrelsesammansättning i förändring - ett könsperspektiv
The absence of female directors on Swedish corporate boards is currently a hot topic for both politicians and business leaders all over the world. This thesis aims to discuss reasons for the scarcity of women on boards in Swedish publicly listed companies as well as what actions are taken to alter the composition of these boards. A rigorous selection of gender theories have been used together with data collected from in-depth interviews with mainly board members and nomination committees. Extensive analysis has led to findings that historical perceptions of differences between men and women linger as of today, which prevents women to reach top executive levels as well as board positions. The increasing use of headhunters has encouraged companies to look beyond male-dominated networks in an attempt to widen the range of potential board nominees.
Från Monopol Till Konkurrens : Telias hantering av den ökande konkurrensen genom förändrade marknadsföringsstrategier
The Swedish telecommunication market was prior to the official deregulation 1975 characterized by Telia?s former monopoly position. This thesis studies how the deregulation of the market, and the thereby increasing competition, has affected Telia and how it has influenced Telia?s marketing strategies.The theoretical framework, from which the conclusions will be made, is a combination of the theory about strategic learning behaviours by Slater et al, and Grönroos? theory about a marketing continuum. The empirical work material is the result from two interviews with former key figures at Telia, and a briefing of Telia?s annual report between the years 1993 and 2006.Research findings indicate that Telia has gone from being product oriented with a strong technical focus, to becoming gradually more market oriented with competition orientation but foremost customer orientation as their most distinguished learning behaviours.
Framtidens energilagring : en studie av befintliga samt potentiella metoder fo?r lagring av fo?rnybar el pa? ett ha?llbart sa?tt
In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.
Kriminalvårdares föreställningar om äldre interner och deras omsorgsbehov - en kvalitativ studie
According to the statistics, the number of older inmates in prison is increasing, and the care needs for this group are relatively unexplored. The purpose was to study prison officer?s perceptions of older inmates and their care needs. The study was based on a qualitative approach in which prison officers at one prison were interviewed. The interviews were analyzed based on earlier research and from a social constructionist perspective.
Situationsanpassat ledarskap för byggproduktion
A large cost at the construction sites today is the labour cost of the workers. But unfortunately the worker potential is not used to full. It is not unusual to take into a count with a work-?place-?additional-?time of 50% in some cases. By increasing the workers' motivation and responsibility for their tasks may reduce the time considerably, which also increases the potential for greater gains in construction projects.By using the situational leadership may the workers level of maturity develop entirely.
Allmänsjuksköterskans problematik kring bemötandet av den HIV-positiva patienten i den somatiska vården
The number of HIV- positive is increasing all over the world and it's very likely to meet these patients as a nurse. The interaction between the nurse and the patient is characterized by experience and knowledge and at the same time the nurse is expected to act professionally. The purpose of this literature review is to investigate the nurse's complex of problems regarding the treatment of the HIV- positive patient by exploring the attitudes against HIV among nurses and how the nurse can maintain the integrity of the HIV- positive patient. Antonovsky's salutoqenic model, sense of coherence, has been used as theoretical frame. From 14 articles five topics have been found that influence the nurse's attitudes against HIV-positive patients.
Göteborgs stadsmuseum mellan teori och praktik - En diskursanalytisk studie av museiverksamhet i en ökat marknadsorienterad omvärld
The aim of this Master?s thesis is to research how the Göteborg City Museum places their organization in a context of culture policies andmuseology.The discursive analysis constitutes the methodical frame for this thesis. According to the analysis of this thesis, since an increasing influence of a market-oriented discourse, an antagonism between a sociological pathos and a market-oriented instrumentality seems to be the major theoretical clash at the museum. Inside the organization though, the personnel lacks broader insights concerning these theoretical conflicts, but the stressed economic situation creates no room for further theorization. There is a risk to get caught in a market-oriented discourse where there is no time to reflect on the effects of the discourse because of the lack of time that the discourse itself generates.
Ungdomars attityder till det omgivande samhället : En enkätstudie av 35 ungdomars attityder analyserat utifrån socioekonomiska faktorer, uppväxtmiljö samt fritidsvanor
Youths tend to have a bad reputation. Their outspokenness and spontaneity are two of many reasons to why they are seen as rude and disrespectful. The creativity, curiosity and not least the courage to have opinions and attitudes are in such young age not yet weakened. Youths, their thoughts and attitudes change quickly. This essay will deal with a selected group of youths and their attitudes to the surrounding society.
Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.
A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.

Värmebehandlat trä ? att inhämta synpunkter i produktutvecklingens tidiga fas :
This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today.
The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes.
My main purpose with this study is to look into customer involvement in the early phase
of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.
