Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

When Swedish authorities are to purchase or rent something, public procurement is used as a means to an end. Authorities as well as suppliers are subjects to the fact that Swedish law regarding public procurement regulates the form of procurement in one set of particular regulations (LOU) and the form of contracts in another set of general regulations (AvtL). Suppliers and purchasing authorities close a contract regarding the subject of procurement and the law of public procurement regulates when such a contract can be closed, simultaneously the law of contracts regulates when parties are held to contracts and when contracts are to be rescinded. I investigate in this essay what these two types of regulations can result in for the contracting parties. As it is today agreements that have been entered into wrongfully still are valid, even if a court of law nullifies the procurement and sentences the purchasing authority to make a new public procurement.

My essay is written from a basis of one of my own experiences were a child is perceived by us pedagogues as lonely and introverted, as well as having trouble socialising because of, what we can see, difficulties making himself understood verbally. I want to highlight how I as a pedagogue can respond to and strengthen children who are outside but still with the group, in a certain sense. I want to reflect on how we can deepen our understanding of these children and how we can facilitate for children who do not follow the norms of society when it comes to communication. I will analyse and draw conclusions with the help of theorists such as Jean Piaget and Lev Vygotskij and interpretations of these, but also look at it from a sociopsychological perspective as the interactions between people and environments play a large and distinctive role in preschool. The purpose of this essay is to enlighten how different we can see and experience situations in preschool.

   To work and live in the same place where ones employer also is the landlord, can create a situation with many special requirements for the individual. Constrains regarding time, space and impact on social life is likely to appear. Based on theory and empirical research about the Boundaryless work and the Psychological contract the purpose of this report is to examine employees who live and work at the same place. This is done by studying the regulation regarding time and space factors and the psychological contracts in expectations and in violation of the psychological contract and the risks associated with this like Locked-in factors. The study includes interviews with managers and employees (n=9).

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

This study is about differences in knowledge regarding animals. In the study five year old preschool children from a city were compared to five year old preschool children in the suburbs with multicultural background. The study is also about where children´s knowledge about animals comes from and how educators can make a positive difference. To find this out standardized interviews was used on 23 children from four different preschools, two preschools in the suburbs with 15 children and two preschools in the city with 13 children. A survey was sent out to the educators within these preschools to gather background information on what the children do regarding animals.

The purpose of this study is to investigate whether intensive teaching of reading strategies at an individual level can affect reading comprehension for students in second grade. A quantitative method with quasi-experimental design is used. All students in the experimental class trained on reading comprehension strategies at their particular level five times each. Before and after training a reading comprehension test was made. The reference class did the same test.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Deep litter is a system for animals kept in separate stalls, loafing and bedding in wind shelters. The litter can consist of different bedding, like straw and peat. The system is allowed to build over and to ensure optimal proportions it is necessary to add new straw regularly and to have good conditions. Important conditions are aerobic state, humidity, amount of organic substance and acceptable temperatures in the litter. The micro organisms are depending on temperature for their living conditions and to get the bottom layer in the litter to start burning.

This is a qualitative study with a hermeneutic and partially inductive approach. The study?s purpose is to enhance the understanding of young adults experiences of unemployment and the importance of being employed. In this study, eight young adults participate in the project Framtid Kronoberg. The youths are 19-25 years of age.

Today there are no analgesic drugs approved to be used in goats. Drugs approved for use in other species are consequently being used without knowing the pharmacokinetics of these drugs in goats. The purpose of this study was to investigate the pharmacokinetics of the opioid butorphanol when given subcutaneously in goats. Subcutaneous administration might extend the half-life compared to intravenous or intramuscular administration. Eight clinically healthy, non-pregnant 6 months old female goats were used.

The purpose of this thesis is to study the context that affects crisis communication through an organizational perspective. It also tries to identify factors of success and difficulties when it comes to coordinating information between governmental organizations during a crisis. Carried out as a case study of the Swedish governmental network Krissamverkan Kronoberg, the method used are source analysis and qualitative interviews with members from different organizations in the network. The results have been analyzed through Organization theory, Network theory and theory in Crisis Communication. The context that effects governmental organizations ability to cooperate during a society crisis is characterized by knowledge, understanding, utility and willingness. In addition to this a successful coordination of information should be based on resources, competence and continuity. The main problems when it comes to cooperating and coordinating during a crisis situation lies in what we would like to call organizational egoism, existential uncertainty and defensive behavior. .

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.

The aim of this study was to examine how "Professional Exes", individuals that have exited a drug abuse and a criminal career and further are educated to work in the addiction field, transformed their identity and which factors that were significant in the process. The result of this study are based on semi-structured interviews with five Professional Exes and shows which specific factors in the process that contributed to the transformation and what kind of difficulties and barriers that existed during the process. The study suggests that, among other things, identification with others exes and the 12 Step Program are significant factors in the process. Furthermore, the study suggests that a difficulty in the transformation is that residues from the previous identity such as a poor self-esteem occurred in some situations..
