Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.
A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Ämnsövergripande arbete i skolan : i samarbete med bild
The aim of this bachelor thesis has been to examine and develop our own understanding about how young people in Sweden (16-29 years of age), take part in cultural activities. As librarians it is important to know what kind of activities and interests this particular group has. With Pierre Bourdieu?s theoretical framework towards habitus and capital we are interested to see if there is a connection between one?s cultural use and background, if different access to capital with or within groups has an affect or not. With both statistics and interviews with people within our target, we believe this data has been sufficient enough to conduct a good and valid study.
Kroppstemperatur och vattenavdunstning via huden hos extremt underburna barn vid vård i kuvös och med kängurumetoden
Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

Kulturmöten - problem eller möjligheter?
This work is about Cuban music and my relationship to it. My study contains two different parts. In the first one I try to give a short summary of Cuban music history. The second part is about possibilities and problems that can arise in the meeting with foreign cultures. I have focused on three themes: Music and respect, cultural encounters and travelling, and communication.
Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder
The mining industry, in terms of ore excavation and metal production, is and has been
important to the Swedish economy. In connection with the ore excavation process, large
amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage
(AMD). This water may reach the nearest surroundings and cause negative environmental
effects. By covering the waste with soil or water, the oxidation process can be minimised.
At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between
1951 and 1991.
Nej, inte rita. Låna!: 3-4-åriga barns informationsbeteende på folkbibliotekets barnavdelning
The aim of this study was to examine how children in ages 3 to 4 use the public library with the research questions: What does children?s, in ages between 3 and 4, information behavior look like when they visit a public library in leisure time with a parent? What is the nature of interaction between child and parent, child and the staff of the library, and between child and other visitors? What is the function of the cultural tools in relation to the children?s information behavior? The theoretical frame of reference consisted of Lev Vygotsky?s ?the zone of proximal development? and Roger Säljö?s theory about using cultural tools. To answer the questions I have observed 4 children together with their mothers and siblings at a public library. From the result of the observations I found that every child had their own information behavior. Two of the children only used one kind of cultural tool ? books.
Socialt arbete med ensamkommande flyktingbarn : En kvalitativ studie om hur socialarbetare upplever det tvärkulturella arbetet med ensamkommande flyktingbarn
The purpose of this study was to examine how some social workers in Sweden describe the social work with unaccompanied children. Emphasis was on the role of culture in social work with the unaccompanied children. I wanted to examine how the social workers describe their view on social work with unaccompanied. I also wanted to examine how the social workers describe their view at their own and the unaccompanied children?s cultural backgrounds influence on the social work with the unaccompanied.
Rimbo våtmark : en förstudie på förväntad kväveavskiljning och lämplig växtlighet
This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.
Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.
På grund av dålig arbetsmiljö?
The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.
Trygghetens betydelse för fritidshemmets vardag
In my essay I'm studying what aspects of the school environment that influences the pupils experience of safety and what aspects that strengthens the experience of safety. I'm introducing three different dilemmas from three different places in the school environment. The three dilemmas have that in common that they focus on safety. I'm introducing the after-school centre commission according to the National Agency for Education, presenting results and theories from various researchers and authors about how you can work with safety regarding children's development and learning. My conclusion is that safety is a very important aspect when it comes to learning and for the overall development of children.
Sverige och implementering av EU-direktiv : En fallstudie av badvattendirektivet och arbetstidsdirektivet
The aim of this paper is to explain and compare non-compliance of two EU-directives, ?the quality of bathing water? and ?the working time directive?. This study answers the questions: Why didn?t Sweden implement the directive on bathing water quality and the working time directive correctly? Are the reasons for non-compliance the same or different in the two cases? The paper is designed as a case study and with an explanatory attempt we explain why the two directives weren?t implemented correctly in Sweden. The theoretical approach is based on both general- and EU-specific implementation theories.
