Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

Mitt syfte är att undersöka TV som barnkulturellt medium; var det befinner sig på det barnkulturella fältet, vilka emotionella responser det förmår väcka hos sin publik och hur både diskurser om barn och barndom och existentiella frågor formuleras i TV-dramatik för barn. Jag har analyserat fem TV-serier (Vi på Saltkråkan (1964), Ebba och Didrik (1990), Barnens detektivbyrå (1991), Du måste förstå att jag älskar Fantomen (1981) samt Rädda Joppe ? död eller levande (1985)) med fokus på just barndomsdiskurser och existentiella frågor. Mina teoretiska utgångspunkter har varit flera då jag försökt hitta en tvärvetenskaplig ingång till mitt ämne. Teorier om kultur och populärkultur, kultursociologisk teori och diskursteori är utgångspunkter, som jag kombinerat med mer specifika teorier om TV, barns TV-tittande och receptionsteori.

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Syftet med studien var att synligg?ra hur barn och unga framst?lls i relation till f?r?ldrar och familj i BBIC grundbok, genom att kritiskt granska materialet med hj?lp av WPR. Empirin bestod av handboken BBIC grundbok (Socialstyrelsen 2023), ett dokument med samlade riktlinjer f?r arbetss?ttet BBIC som v?gleder barnav?rdsutredningar inom socialtj?nsten i Sveriges samtliga kommuner. Studien som ?r en dokumentanalys pr?glades av en socialkonstruktionistisk f?rst?else och empirin bearbetades med teoretiska begrepp fr?n WPR tillsammans med teoretiska begrepp fr?n barndomsstudier, kritiska barndomsstudier och queerteori.

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

The de-regulation of commercial air traffic in the early 1990?s lead to that many new airline companies entered the market. Many of these new actors were low budget airlines which meant that the traditional airlines met a new type of competition. This situation contributed to the fact that ticket prices dropped in many countries. It has become more and more common that the traveller prefers to fly with low budget airlines rather than with the traditional airlines.

I Sverige mördas 17 kvinnor om året av en man de är eller nyligen har varit i intimt förhållande med. Det innebär en kvinna var tredje vecka. Omständigheterna är oftast de samma. Separation, med kvinnan som drivande part. Mannen de lämnar är svartsjuk och av kontrollerande typ.

The municipality of Sandviken is in a state of strong growth. This affects the need for more hotel rooms in Sandviken, in a way that it?s profitable to invest in a new hotel. Sandvikens largest company, the steal industry Sandvik AB, grows just like Sandviken, and have great influence on the need of more hotel rooms. Today there are three hotels placed in Sandviken, and these hotels aren?t enough when the pressure of hotel guests is at its top.The purpose with the project was to analyse the criteria?s that are important for localization of a new hotel in the Sandviken, and to clarify what kind of hotel Sandviken is in need of.

The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

Denna studie syftar till att titta på bilismen, som bidrar till en stor miljöpåverkan, ur ett genusperspektiv. Den syftar även till att jämföra med tidigare studier för att titta på hur detta stämmer överens med norrköpingsbor. För att ta reda på detta har en kvantitativ studie i form av enkäter utförts med ett urval på 100 respondenter för att på så sätt representera Norrköping. Denna metod hjälpte till att svara på de ställda frågeställningarna. För att titta på sambanden mellan könen och mellan olika frågor i enkäten har ett chitvå-test utförts.Resultatet av studien visade på att förväntningar kring mäns och kvinnors beteende och relation till bilen som fordon existerar i Norrköping, men att vanorna kring bilanvändandet istället speglar en annan bild.

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

New technology and urban sprawl have resulted in almost half of the population in Sweden being insufficiently physically active. The sedentary lifestyle causes heart- and vascular diseases, diabetes, high blood pressure, cancer, stress etc. in the population. One of the biggest priorities in the society is to promote more physical activity. Through literature studies and a questionnaire this paper will examine how we can design the built environment in order to promote physical exercise and if we can change the sedentary lifestyle with a outdoor environment that invite physical exercise. There are both internal and external factors that have importance for people?s physical activity.

In the low-income countries of the world, rapid urbanization and decaying infrastructure results in an increasingly unsustainable situation when it comes to solid waste management. Often, the solution tends to focus on introducing technical advanced interventions based on the conditions of the high-income world. However, this thesis aims to ?nd site-speci?c solutions on solid waste management at a local scale. By taking in consideration of local conditions a customized approach is possible where the solution is not dependent on expensive structural changes.
