Dokumentation av ensilering med fokus på clostridiesporer i mjölk :
To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.
Minskande andelar kraftfoder i foderstaten under betesperioden : effekt på mjölkavkastning och betesbeteende hos mjölkkor
Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.
Ledarskap på bibliotek En studie av tre högskole- och universitetsbibliotek
This essay is about leadership in libraries within the academic world, i.e. leadership in research libraries. To place our survey in a context we begin the theoretical review with a chapter about organisation theory. We dont think its possible to separate the leader from the organisation so we wanted to describe the organisation and its effect on the leadership. The next theoretical section is about leadership research.
The cow eye-Function and effect of light on milk yield
The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye.
Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.
Spelvärlden som informativt grafiskt gränssnitt : En studie om hur spelvärldens visuella uttryck hjälper ovana spelare att förstå mål och regler
The diegetic game world places high demands on how it is designed. It is common that game developers wants to create a deeper player immersion and some developers believe to achieve this by integrating HUD elements into the game world. To find out how digital games can rely on the design of the game world, we performed user studies on beginners who have very limited experience of playing digital games. By observing the beginners, we could discern the visual aspects in the diegesis that helps players understand the game rules and objectives because the beginners won`t make their choices based on previous gaming experiences. If players encounter a variety of difficulties to understand the rules of a game, then it will less likely be a successful game.
Alternativa metoder för avhorning av kalv : teknik och behandlingseffekt, samt utvärdering av postoperativ smärta med användning av NSAID
In this study, cortisol in saliva and pain related behaviours in calves were used as markers of distress when comparing two different dehorning methods; scoop or cautery. We also investigated the effect of a non steroidal anti-inflammatory drug (NSAID), meloxikam, on postoperative distress after dehorning with either dehorning scoop or cautery iron.
Twenty calves were dehorned on one randomly chosen side by scoop method and on the other side by cautery. Five months later, the effect on horn growth was investigated. Horn production was observed in seven of the calves.
Makars pensionsrättigheter i bodelning med anledning av äktenskapsskillnad : Särskilt om tjänstepensionsförsäkringar när make har bestämmande inflytande över sin arbetsgivare som äger försäkringen
The collective agreement contains many important provisions concerning the relationship between employers and employees. When a collective agreement applies in the workplace, both employers and employees are bound by it. However, only employers of those two, can take part in the collective agreement, and therefore negotiate the content of it.The purpose of this study is to answer the following question: Why are rules that has been interpreted in collective agreements not expressed in writing? Therefore, the Swedish collective agreement system will be examined, and a distinction between types of silent regulations will be made to find causes. The potential for workers to act on a collective agreement with quiet regulations will also be examined.Collective agreements are signed on three levels: central, union and local levels.
Gemeinschaft eller Gesellschaft? Biblioteksfilialerna i Kalmar kommun och det globaliserade IKT-samhället
This masters thesis aims to explore the branch libraries in Kalmar municipality and their relation to the Information and communication technology ICTsociety. How do they adapt to and assimilate with, the ICT-society? What are their roles in local social networks and do they make a difference there? To answer these questions, critical discourse analysis, CDA, as founded by Norman Fairclough is applied to four interwievs with branch library managers. Other theorists used are Michel Foucault, Chaïm Perelman and Ludwig Wittgenstein. A solid description of todays society on different levels is also given.
Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar
Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.
Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota
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.
Cytokinuttryck vid vaccination med olika vaccinkoncept mot FIP :
Feline infectious peritonitis (FIP) is a feline viral disease with high mortality. There is no cure or any effective vaccine available today. Many questions are yet to be answered about this disease and the immune response in affected cats.
The aim of the study is to evaluate two different techniques for the study of cytokine profiles in cats vaccinated with a vaccine concept against FIPV. More information about the immune response in these cats could give valuable information to better understand the pathogenesis of the disease and the development of an effective vaccine.

In order to increase the physical activitylevel in people they need to feel motivated and there are many factors that can motivate people. The purpose of this survey is therefore to explore the leaders of PaP and their thoughts about whatmotivates clients with PaP to increase their physical activity levels. This is explored by aqualitative method incorporated with semi-structured interviews with four respondents who workswith PaP.
Inflammatory cytokines induced by Bovine Viral Diarrhoea Virus (BVDV) in Peripheral Blood Mononuclear Cell (PBMC) subsets
Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.
Personlighetens inverkan på aktivt och passivt jobbsökande, karriärambition och arbetstillfredställelse
Previous research has focused limited attention on how personality affects job search for university educated people in work and no studies have focused on the difference between active and passive job seekers. This survey-based study that examined university educated economists and engineers with 5-25 years of experience, showed that career ambition mediated active job search for the personality dimensions of openness, agreeableness and extraversion and also gave clear evidence that active job seekers have lower levels of job satisfaction, and higher levels of career ambition, agreeableness and extraversion, compared with passive job seekers. These findings provide a more nuanced picture of the impact of different recruitment strategies and provide a starting point for in-depth studies on passive job seekers.
Public Welfare vs Return on Shareholders´Equity -A Case Study of the Translation & Implementation of the Management Control Systems in Systembolaget
Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.
