Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

Många sjöar är idag påverkade av mänsklig aktivitet, bland annat är 1 % av Sveriges sjöar eutrofierade, däribland Ekoln. Ekoln är en stor sjö i Uppsala län söder om Uppsala som länge varit eutrofierad. Fyrisån och Örsundaån är de största inflödena till Ekoln och Sävjaån är ett betydande biflöde till Fyrisån. Kungsängsverket är Uppsalas reningsverk och har sitt utlopp i Fyrisån och som ett led i att minska eutrofieringen byggdes fosforreningen ut 1972. Fosforhalterna i Ekoln sjönk och algblomningarna blev färre.

The purpose is to examine social workers view of vulnerable children and their needs. We are also interested to know how social workers think and discuss concerning the help these children are given. Our main questions in our study are; How do social workers define vulnerable children? Which needs do vulnerable children have according to social workers? Which opportunities and difficulties might there be in the decision making when trying to help these children? Which public authorities do social workers cooperate with? Which opportunities and difficulties do social workers find in the cooperation?This study is based upon interviews with ten social workers in the social childcare division in different municipalities in Skåne region, Sweden. Our results are explained and analyzed with a qualitative approach through different aspects of power- and Human Service Organization theories.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

The workplace is for many associated with joy and commitment, for others it is associated with fatigue, inadequacy and cynicism that is explained as the three dimensions of burnout. A general view of burnout is that it is an individual problem that many companies ignore, because a preventive task does not generate immediate profits. This has been a growing problem for years. Burnout costs not only money but also time and knowledge. Unfortunately, the popular belief is that "If it ain?t broke, don?t fix it." Organizations that think this way are sacrificing future benefits for short-term gains.

Good conditions in the workplace, fairness in the workplace and the social differences contribute to a general improvement in public health.

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

The purpose with this essay is to find out how aware students are about the environment, andif they believe that their actions can influence the environment. I have used both earlierresearch and questionnaire surveys in order to fulfill the purpose. In earlier research, I haveused research based on materials that are scientific. According to the researchers it isimportant that the children and young people become involved and dedicated to theenvironment and its surrounding world. It is important to listen to the children's thoughts andvisions as they are aware about what happens, but do not reflect on the worst, but hope that itbecomes an improvement in the future.

Introduction: Good hand hygiene practice is the single most important measure to reduce the spread of bacteria and viruses in healthcare. For nurses, this has become more important as the spread of multidrug-resistant bacteria in hospitals is increasingObjective: To identify factors that are important for adherence to hand hygiene among health care workers with patient contact.Method: Systematic literature review. Original articles were searched in PubMed and Cinahl.Results: Factors of importance for compliance was profession, lack of time, knowledge/education, physical work environment, attitudes toward hand hygiene, and dry hands.Conclusion: More education, less workload and more visible placement of hand disinfectant containers are examples of actions that could lead to the improvement of staff hand hygiene and reduce the incidence of healthcare associated infections. Due to the fact that health care workers around the world have different training and approaches, the result of this study may be difficult to use. To increase adherence to hand hygiene, a similar study limited to a specific country, such as Sweden, would therefore be interesting to carry through.Keywords: hand hygiene, Infection Control, Compliance..

Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.

The aim of the study was to describe how managers at the eldercare system especially in nursing homes work to ensure high quality care. For this purpose, a qualitative method was used in this study and four managers at nursing home have been interviewed. Previous studies have shown that managers in some cases are restricted in their actions and that this may slow down the improvement of the care. At the same time the managers describe their work as demanding and diverse. They have a significant staff responsibility, meaning that they have to ensure the quality of care.
