Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.

The purpose of this study was to illuminate dentists? work with guarantees. A case study was performed by personal interviews with dentists from both private and public sector. The result showed how dentists work with guarantees and how they motivate their guarantee obligations. We found that service guarantees? shaping and application should be simple and obvious.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

Background: Basic hygiene is an important measure to prevent healthcare associated infections, save patients? lives, and reduce economic costs for health care. Healthcare associated infections are a threat to patient safety. In community care persons who are the care takers are a risk group and nurses must make sure that basic hygiene procedures are followed.Method: Literature studies with descriptive design, article search in databases Cinahl and PubMed. The results found are based on twelve chosen articles.Aim: To describe factors related to adherence to basic hygiene and how nurses in community care can help to improve compliance with these procedures.Results: In the nursing staff and leadership in health care interest in and the understanding of basic hygiene is described as being of most importance.

The mobile jukebox is an idea for a new kind of smartphone application that would allow users to dictate the music playing at various establishments. The mobile nature of the innovation allows for the possibility of a more ubiquitous service. Conducting a quantitative as well a qualitative study, the authors have found significant interest in this innovation service among potential users and potential distributors of the service. Furthermore, it is shown what aspects are important for decision makers to make a decision on whether to integrate the service into the operation of potential distributors of the service.  .

Retinoscopy, also known as skiascopy, is an objective method for assessing therefraction of the eye. This method has been used for a long time, both in animalsand human patients. According to the literature, it has been postulated that it is notnecessary to obtain cycloplegia before the examination in lower mammals. Someauthors even mention that it can make the examination more difficult. Therefore itis not recommended.

Sectra Mameas is a medical technology company in an expansive phase that is planning to increase its volume capacity with 50 % in the beginning of 2009. This to be able to deliver the increased number of systems that the customers request. To be able to produce more units the takt time of the assembly line needs to be shortened. This could only be done by identifying and solving recurring problems. To be able to find the problems, create a common knowledge of which these are and eliminate them the production department of Sectra Mamea needs to visualize certainKey Performance Indicators (KPI) in the organization.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.
