Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with the measured time of usage.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

A litereture review about how significant treatment with respect is for patients with another cultural backgraund.

The objectives of this experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.

Clinicians in veterinary practice have responsibilities for the development of global antibiotic resistance. In some cases, antibiotics are contraindicated or even useless in wound treatments and therefore other options are needed. Antiseptics may be another option but their use are controversial and may be questioned by owners. As professionals, it may be very difficult to be able to motivate this choice of treatment. The aim of this paper is to gain knowledge about four antiseptics; iodine, silver, polyhexamethylene biguanide (PHMB) and honey to make it easier for veterinary nurses and other clinicians in veterinary practices to decide their potential use. The assessment will be made with consideration of the available evidence concerning the properties, usability and the animal?s experience. The results showed a lack of evidence in in-vivo studies in horses, particularly studies within the field of veterinary nursing.

The aim of this paper was to describe the phenomenon of threats and violence within a Swedish penal institution. The study was thematized according to the three main research questions. These were as follows; The threats and violence prison staff have experienced in their workplace (I) how these experiences affected them in their work performances (II) and in their private life (III). By a qualitative design, in-depth interviews were carried out with four persons who are, or formerly have been, gainfully employed at a penal institution. Concepts from the theory of symbolic interactionism and a theory of human action have been used in the analysing process of this paper.

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.

On the 26th of January 2010, the Supreme Administrative Court in Sweden gave five rulings which greatly affect the possibility to keep a close company within a family by transferring the ownership of the company to the next generation. The five rulings concern the interpretation of the prerequisite, same or similar activity, which can be found in section 57, clause 4 of the Swedish Income Tax Act.    The prerequisite is fulfilled when an entire or parts of a business is transferred to another close company and the receiving company?s business activity is within the framework of the transferring company?s business activity or when the companies have a similar connection. Depending on which shares that are being evaluated, the prerequisite can refer to both the shares in the receiving or the transferring company. When the prerequisite is fulfilled, a standardized amount of the business income will be taxed as capital gains and the surplus will be taxed as earned income.

AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.

Background: Vacuum assisted closure, VAC, is a method which can benefit wound closure. There are not many reliable studies about the effects of VAC in different types of wounds. Previous studies have shown that patients have experienced pain during dressing changes.Aim: The aim of the study was to survey in what kind of wounds the vascular surgery ward have been using VAC, to study the treatment process of VAC and how it has been documented and also to investigate if patients with VAC experienced pain during dressing changes.Method: The patients were chosen from a ledger, which contained 77 patients that had been treated with VAC on the vascular surgery ward. Data were collected with a journal survey protocol.Results: The result is based on 67 patients with a total of 79 wounds. VAC was shown to have a good effect on wound healing and infected surgical wounds were the most commonly wound category undergoing treatment with VAC.

The cooking liquid is called white liquor.

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.
