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.
Analys av dricksvattenrening med metoderna Mikrobiologisk riskanalys (MRA) och God desinfeksjonspraksis (GDP)
Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
Våga inte blunda : en studie om förskollärares syn på anmälningsplikt enligt socialtjänstlagen
The aim of this study was to capture preschool-teachers thoughts and experience basing on the obligation. Are there any policies and procedures for preschool-teachers to use when suspicion that a child is being abused occur. Are there some factors that may affect preschool-teachers to report to the social service? How does the preschool-teacher find the contact with the Social Service? I conducted four interviews with four preschool-teachers, two of these preschool teachers are employed at the same municipal preschool and the other two are employed at two other preschools. The interviews were semi-structured and were conducted at each individual?s workplace.
Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.
Såromvårdnad på reptiler
As reptiles are becoming more common as patients in veterinary clinics, there is a need for creating new procedures regarding the care of exotic pets. The aim of this study was to develop a wound care routine adapted to reptiles, which can be used independently by a veterinary nurse due to the absence of prescription drugs or surgical techniques. The study was conducted by compiling the available research regarding wound care in reptiles, as well as research from related fields.
The result indicates that polyurethane films and chlorhexidine-alcohol may advantageously be used on these patients. Hydrocolloid dressings and silver sulfadiazine dressings have adverse effects on wound healing and should not be used routinely in reptiles.
Kvalitetssäkring av servicelämnare för skogsbrukets arbetsmaskiner : Intervjuer och förslag till utveckling
In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..
När Hulken mötte Barbie : -Pedagogers förhållningssätt till könsstereotypa leksaker i förskolan
The aim of this study is to investigate how preschool teachers reason about gender stereotypical and gender neutral toys and other material. I would also like to see how the pedagogues reason about gender segregation when it comes to toys. To investigate the issue, I have interviewed three pedagogues from different preschools. The results showed that the work procedures differed a bit from school to school, although they all wanted to achieve the same goal. A goal that our curriculum mention as well: Not to make a difference between boys and girls.
Att aktivera deltagande : Design av ett crossmediakoncept
In this thesis we present the procedures and outcomes of adopting two roles in a study: the role of a researcher and the role of a designer. The subject is crossmedia design. Crossmedia is a growing and changing trend for media producers of today its design is of great importance. The purpose is to create a concept from scratch that stands out from the crowd and engage people with the use of cross media as the approach. We also aim to investigate if a cross media designer can rely on previous research made within this subject or if the scene has changed.In order to test and to fully understand the process of the subject, we designed a crossmedia concept, based upon previous and related research.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.
Normbrytande beteende : en studie av uppfattningar och resonemang hos kuratorer på högstadieskolor
The purpose of this paper is to investigate how staff at secondary schools are thinking and reasoning about notifications to social services based on norm breaking behaviors in students. To find this out five qualitative interviews has been made with counselors in two public schools and three private schools in Örebro län. The results show that there is no clear definition of what norm breaking behavior is which making the reasoning difficult. There are clear procedures for the staff to dealing with norm breaking behaviors but they do not know when they will be applied. The decision to report behavior to the social service is usually not taken individually, it is a result of several people?s views and experiences.
Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?
This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.

Kvävemineralisering från stallgödsel beroende på olika grad av inblandning i mark
The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.
