Fieldstudys on 22 farms (23 silos) to study relationships between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us. Particle size of maize silage was determined using the New Penn State Forage Particle Separator. SLU Skara made a special sieve for us, that had larger holes than de original sieves. The samples were shaken after instructions and then the material was weighted. We have also been taking out samples for microbiological analyses from the silos on 13 of the farms.

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

I detta examensarbete har Stockholmsbörsens historiska utveckling under perioden 1919 ? 2003 analyserats. Arbetet har genomförts med handledning från SEB Enskilda Banken och Institutionen för produktionsekonomi vid Linköpings tekniska högskola.De viktigaste resultaten som dras ur detta arbete grundar sig främst på statistisk analys av historiska tidsserier över totalavkastning, direktavkastning, inflation och BNP-tillväxt. Först har Stockholmsbörsens totalavkastning analyserats och dess egenskaper presenterats. Här kan nämnas att utdelningarna spelat en stor roll för den historiska totalavkastningen, återinvesterade utgjorde dessa cirka 62 procent av den årliga reala totalavkastningen på 6,6 procent under perioden 1919 ? 2003.Vidare har Stockholmsbörsens direktavkastning och dess betydelse som värderingsmått studerats.

The understanding of the role of nature for rehabilitation of both physical and psychological afflictions has greatly increased in the last few years. There?s a lot of science that describes the healing effects of nature. The rehabilitation garden in Alnarp has contributed with very positive results from the treatments of patients with burnout syndrome. In the first stages of rehabilitation, the need for calm is very important and a demand-less and stress-free environment is of essence.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

In a competitive market as supermarkets, hundreds of the same products fight for attention in the shops. Every day thousands of targeted advertising messages is given to us. As a natural result of all this, power is transferred to consumers. You can no longer differentiate yourself by only price and function, thus companies must play on the emotional aspects and create a relationship with consumers. A key to success is to understand people's emotional needs and then satisfying them.In various journals and papers you can find highlighted success stories of strong brands such as Harley-Davidson, Apple and Virgin Airlines.

Flexicurity is a union of the English words flexibility and security. The union of the two words to one common term, hints that flexibility and security does not have to be each others counterparts in order to achieve good economical development and employment. Flexicurity, as it is found in Denmark, is described as a three part model composed of active labour market politics, generous financial compensation in the case of unemployment and flexible labour law. The existence of strong collective agreements and three part cooperation is of great importance for the good flow of the Danish model. The same goes for education of different kinds.

Abstract This Concept Analysis according to Walker & Avant (1995) studies the concept of uncertainty in the nursing context. It consists of four parts where uncertainty in general have been encircled in a semantic analysis (part one) and a qualitative content analysis consisting of an questionnaire, distributed to the staff members at one nursing and medicine institution, with an open question about the meaning of uncertainty (part two). The third part is a literature study of the nursing context to find out how uncertainty is described (part three). Part four is the actual concept analysis based on the three first parts. Uncertainty in the nursing context is an individual conscious experience witch is changeable and impressionable. It is chained together with its antecendents and consequences.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership! This degree thesis is meant to answer the question about which the optimal extension would be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.

"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891 Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.

Racial discrimination is a highly topical and burning issue, of special interest in working life. Most researchers agree on that discrimination is a problem in the Swedish labour market. To counteract the ongoing discrimination, a new Anti-Discrimination Act was founded in 1999. The Racial Discrimination Act although appears to be ineffective on the basis of legal usage. Of all the legal cases about racial discrimination in the labour market, there has only been one sentence of guilty stated by the Swedish Labour Court.

AbstractDrinking water is an important resource on Earth both for humans and animals. Although most of the surface is covered by water only a small quantity is available as drinking water. Our manner of living creates a lot of pollution which has an environmental impact. Groundwater has a protracted turnover time in the soil and it can take many years before the effects of human impact are detected. The Swedish environmental object is ?Good groundwater quality? which aims to provide a safe and sustainable supply of drinking water today and in the future.
