Restvärmeåteranvändning från absorptionsvärmepumpar : en kartläggning av möjligheter och begränsningar vid Vattenfall Värme Uppsala Block 5

Vattenfall district Heating power plant in Uppsala produces district cooling with absorption heat pumps which leads to a large amount of waste heat that has to be cooled with evaporative cooling towers. The Environmental Court has ordered Vattenfall to survey the possibilities to recover the heat, which is the focus of this thesis.The study begins with an overview of the system, and conditions and limitations for waste heat recovery is examined. In the next step alternatives to recycle the heat is evaluated, either by direct recovering or by upgrading.First, the technical possibility of each alternative is discussed, and then the operation time and the amount of recovered heat is calculated. Those alternatives which are possible are brought further to an economic analysis.The cost of investment for each alternative constitutes the basis for a present value analysis. The results are put together in a table where the total amount of recovered heat is compared with the present value for the different alternatives.

Förebyggande arbete mot mobbning : Lärares erfarenhet av styrkor och svagheter i arbetet med metoderna Friends och Mombus

The purpose of this study is to examine how six teachers, who work in two different schools, assess the methods Friends and Mombus in terms of bullying prevention.

One of the main results of this study is that teachers, in addition to their work with Friends or Mombus, also need to use alternative methods to prevent bullying. Examples of these alternative methods include ?Emotional Intelligence? as well as ?friendship massage?.

Från frihet till fängelse: En studie av klientflödet på Häktet Kronoberg

In the last decades, lean production has proven to be one of the most important organizational paradigms in manufacturing. The lean concept has also spread into the service industry where it is applied within a range of different areas. The wide applicability of lean principles has spurred the authors of this study to apply the principles in the context of the operations of a Swedish remand prison. The thesis examines the process a client of the remand prison Häktet Kronoberg goes through from the time of arrest until he/she is released or convicted and transferred to jail. Based on lean tools and principles, the thesis maps and analyses this process.

Kompostering av organiskt avfall från Gästrikeregionen ? miljöpåverkan av olika behandlingsalternativ

In the coming years, organic food waste will be collected in the region of Gästrikland, Sweden. The collection is planned to cover the entire region by the end of year 2007. To start with, smaller amounts are being collected and transported to a central composting plant in Sala. However, a central composting plant in the region of Gästrikland is projected.The objective of this thesis is to evaluate a number of possible methods for composting of organic food wastes regarding their environmental impacts and localization.There are four scenarios for future composting of organic waste that have been evaluated. There are two that consist of membrane composting, either in Sala or in the region of Gästrikland.

One problem though is that the domestic waste, particularly the source separation, at the three resident blocks for students? isn´t working very well. This creates inconveniences for people and environment as well as decreasing the impression on the estates.This project has had the ambition to improve the domestic waste and increase the amount of source separation at HFAB´s student hostels.

Tranbär ett alternativ till antibiotika? En litteraturstudie om tranbär som prevention mot urinvägsinfektion

Urinvägsinfektioner orsakar ett stort lidande då infektionen är smärtsam och ofta återkommande. Lågdosantibiotika som idag används i preventivt syfte vid återkommande urinvägsinfektion bidrar till resistensutveckling, förlängda vårdtider och ökade sjukvårdskostnader. Syftet med denna litteraturstudie är att undersöka tranbärets effekt som prevention vid urinvägsinfektion, för att eventuellt kunna rekommendera tranbär som alternativt profylax. Som metod valdes litteraturstudie. Resultaten visar att tranbär har en preventiv effekt, som verkar även på antibiotikaresistenta bakterier.

Djuren och den ädla människan : Aristokratins roll i den svenska djurskyddsrörelsens framväxt 1875-1905

The aim of this paper is to analyze the influence that aristocrats in Sweden had on the Swedish movement for the prevention of cruelty to animals, and why especially aristocrats started it. The sources I have been using are speeches and texts written by persons who were involved in the movement. I have also studied rapports from the three largest societies for the prevention of cruelty to animals. In the sources I looked for terms, expressions and opinions that can be paralleled whit the aristocratic ideal and opinion. Things that can relate to aristocratic urban people.

Simningsrelaterade smärtor och skador i axlarna hos tävlingssimmare : Riskfaktorer och prevention

De vanligaste besvären som en simmare upplever kommer från axeln, också känt som simmarskuldra. Syftet med den här studien var att kartlägga vilka riskfaktorer för simmarskuldra som har identifierats och vilka preventiva interventioner som har studerats samt har haft bevisad förebyggande effekt på simmarskuldra. En artikelsökning utfördes i AMED, CinAHL, Google Scholar, Medline, PRIMO, ProQuest, PubMed och Scopus. Preventionsstudierna värderades med PEDros graderingsskala.

Livscykelanalys av avfallsförbränning och biogasproduktion

Livscykelanalys används som metod för att undersöka produkter eller tjänster från ?vaggan tillgraven?. Med hjälp av mjukvaruprogrammet SimaPro utförs en livscykelanalys på förbränning av avfall med energiutvinning. Resultatet jämförs med en livscykelanalys som utförs på biogasproduktion från matavfall, för att visa vilken av processerna som har mer positiv påverkan på miljön. Resultatet visar att förbränning av avfall bidrar till minskad miljöpåverkan med 63,9 kg CO2-ekvivalenter per ton avfall.

Arkitekttävlingar : fallstudie : projekttävlingStockholmsporten

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.
