Effect of low light intensities on dairy cows? behavior

The animal welfare act in Sweden states that dairy cows need to have at least a dim light present at night, but there are no recommendations for what intensity the light should have. It is unknown how cows perceive and react to low light intensities and earlier studies on this topic are limited. Red light as night light has also been suggested, based on the cows? inability to perceive red light. This have however been questioned. The aim with this study was to investigate how four different light intensities affect dairy cows behavior.

Fenylbutazon - tillåta vid tävling?

Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.

Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Glukos och leucin som potentiellt hjälpmedel i återuppbyggandet av muskelglykogen efter hårt arbete hos travhästar

The aim of the project was to study the effect of oral administration of glucose and leucin on the resynthesis of muscle glycogen after intense exercise in Standardbred trotters. In a crossover design, 11 Standardbred trotters performed a standardized exercise test on two occasions in order to deplete muscle glycogen. The exercise test comprised a warm up period, 7 repeated bouts of exercise on an uphill 500 m slope, and a recovery period. After the exercise test horses received: 1) a solution of glucose and leucine via a nasogastric tube at 0 minutes and at 240 minutes post exercise and a single bout of glucose at 120 minutes post exercise or 2) water (placebo) at 0, 120 and 240 minutes. Blood samples for measurement of glucose and insulin concentrations were collected at rest, when the horses returned to the stables directly after exercise and throughout the 6 hour recovery phase. During the first recovery hour, samples were collected every 15 minutes and then every 30 minutes over the next 5 hours.

Får idrottande elever högre betyg? : en fallstudie på tre samhällsvetenskapliga program för att visa eventuella samband mellan fysisk aktivitet och höga betyg

Abstract AimThe purpose of this study has been to investigate the possible differences in grades and attitudes towards further studies that can be explained by the student?s level of physical activity. The questions we wanted answers to were:- Does students in more sports-oriented programs have better grades than students in more theoretical programs?- Is there a relationship between physical activity and study-results?- Are there any differences in attitudes towards further studies for students at the different programs?- Which other variables could be affecting the students grades?Method The extent of this study has included 3 municipal schools and 6 classes (2 from each school) ? in all 119 students and 6 teachers. 3 different social sciences programs have participated ? two sports-oriented and one without any sports-oriented concentration .

Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Marknaden för skogsvårdstjänster : en undersökning bland privata markägare inom en region i Värmland

This work broadly illuminates the conditions for increasing the commissions of forestry services within the whole, or parts of, the western regions of Stora Enso?s operating area. Through a questionnaire, a survey was made examining whether the owners of the forests themselves do the forestry on their woodlands. This foremost concerns the pre-commercial thinning, but also planting and soil scarification. The survey also shows who are buying the most part of their forestry services and who are carrying it out themselves.

I politik och praktik : En studie av kulturpolitikens inverkan på två kulturbärandeorganisationers retorik

Author: Niklas JohanssonDirector: Olle DuhlinTitle: In policy and practice ? a study of how the cultural policy have effected the language of two cultural institutions.Background: The swedish cultural policy?s raison d?être is to safeguard all the inhabitants right to experience culture. Since 1997 the development in the field has resulted in an economisation and commersialisation were the culture more commonly is looked upon as a mean of reaching a higher rate of employment or financial growth. The concept of cultural planning and new public management are today part of the cultural pollicy debate which in its turn has effected the goals and ways to evaluate fulfillment.Purpose: The purpose of this study is to show how the cultural policy in the swedish regions effect the language in the annual reports of the cultural institutions and how these documents have developed since 1997. This to further the knowledge of ho wchanges in the cultural policy effects the comunication of the cultural organisations.Method: This is a qulaitative study conducted in a inductivly.

Metabolit- och hormonnivåer som tidiga markörer för fruktsamhet och produktionsstörningar hos mjölkkor

During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.

När man inte vet - Patienters upplevelser av att vårdas för ospecifik buksmärta på kirurgiska akutvårdsavdelningar

Introduction: To become acute ill and to be forced to seek treatment involves a difficult but also a vulnerable time for the individual. This acquires a good relationship between the nurse and the patient. At a surgical emergency ward patients with different diagnoses and trauma are treated. What distinguishes this specific type of ward is that care often occurs in a rapid rate and as a patient the environment may be experienced as stressed. The relationship with the nurse at the ward establishes a foundation for how the patient experiences the health care.

Produktivitet i robotcell

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.

Digitala och sociala medier i undervisningen för elevers ökade motivation, delaktighet och måluppfyllelse.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

Svenska kattägares inställning till vaccination

Background: Vaccination is an important part in cats? welfare. It both helps to prevent the individual cat from catching a disease or lessen the symptoms of it, and protects the entire cat population from an epidemic. It is the cat owner who makes the decision to vaccinate or not. Understanding the cat owners? perspective regarding vaccination may improve communication between the owner and the veterinary nurse, which may lead to a higher vaccination rate among cats.

Svenska livsmedelsföretags val av etableringsstrategi : En studie om Abba Seafood och Oatly ABs etablering i Tyskland och Spanien

Since we all live in an increasingly globalized world where goods and money are transported more easily and with tougher competition, it is a natural step for Swedish companies to establish themselvs abroad in order to increase their gorwth rate and reach more customers. Today all of us belong to the same global network and the purpose of this thesis is to investigate which factors are important for companies when they choose to establish themselvs on a foreign market. The focus of the investigation has been the market of Germany and Spain, since both countries just like Sweden are members of the European Union, but still have quite different characteristics. We, the authors, have also been living in Spain and Germany during the time of investigation and writing. The companies we have chosen to look closer into are Abba Seafood, which now has merged with Procordia Food, and Oatly AB.
