This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

Syftet med det här arbetet var att ta reda på vem rederierna anställer, samt identifiera vilka faktorer som påverkar rekryterarna när de ska anställa en ny styrman.  För att ta reda på det har jag intervjuat två rederier som anställer svenska styrmän. Jag valde att göra en kvalitativ undersökning för att kunna ställa lite mer ingående frågor samt att ha möjlighet att ställa följdfrågor. Resultatet blev att det är till stor del de personliga egenskaperna samt den sociala kompetensen som är av störst betydelse så länge de formella kraven uppfylls. Erfarenhet inom sjöfarten eller utav yrken som man kan ha nytta av i sjöfarten är också meriterande samt att man har bra referenser..

AbstractTitle: Environmental demand solutions - a study within real-estate business.Problem statement:Today, the society stands before a permanent accelerated environmental threat. Companiesbecome increasingly over the environmental problems and more companies look over theiractivity and how it influences the environment. Historical the environmental issue has been forgotten and it is first during the end of 1990 the environmental issue intensive has been noticed. Earlier the environmental work?s high costs was the cause, but now the companies realized the weight and the importance of imposing focus on environment commitments and sees it, as an investment.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Syftet med studien är att undersöka om människor som genomgått en utbrändhetsprocess upplever att de under denna tid utvecklats på ett sätt relevant för deras arbetsliv, och sedan med hjälp av teori undersöka om resultatet av denna utveckling kan anses utgöra kompetens. Genom intervjuer med fem personer som efter en tids sjukskrivning för utbrändhet nu själva upplever att de återhämtat sig, framkom att de fått en ny erfarenhet som gett dem insikt i stressproblematik, samhällets regelsystem och rehabiliteringsåtgärder. De har även utvecklat en mer effektiv energianvändning, ökad social kompetens och ökat välbefinnande. I den mån utvecklingen framgångsrikt används i arbetslivet, vilket intervjupersonerna också uttryckte, har den samtidigt inneburit att personerna utvecklat ny kompetens.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder. Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.

Inledning: Såväl politiker, som media och många andra kritiserar undervisningen av svenska för invandrare (SFI) kraftigt, det diskuteras att invandrarna inte lär sig svenska i önskvärd omfattning och integrationen av de nyinkomna går dåligt. Studien har därför velat undersöka dessa frågor SFI-deltagarnas syn på andraspråksinlärning och deras integration.Syfte: Studien avser att undersöka vad SFI-deltagare anser om SFI:s medverkan till integration och andraspråksinlärning i det svenska samhället.Forskningsfrågor: 1. Vilka diskurser framträder i SFI-deltagarnas konstruktioner av vi och de andra?2. Vad är SFI-deltagarnas syn på SFI:s medverkan till deras integration i samhället?3. Hur har SFI konkret bidragit till SFI-deltagarnas integration, avseende t ex arbete, vänner, kontakter, studieframgång, boende och skola?Metod: Diskursanalys enligt diskurspsykologisk metod.Teori: Den här studien har sin teoretiska förankring i socialkonstruktionism med influenser av postkolonial teori och kritisk teori.Resultat: Antagandet var att bristande språkkunskaper skapar segregation och omvänt, vilket besannades. Sammanfattningsvis kan sägas att informanterna uttryckte en massiv kritik av SFI:s förmåga att hjälpa dem med integrationen och att de även var kritiska mot praktik och arbete och mot den språkträning som de då fick. Men de är inte enbart kritiska till SFI-undervisningen, de ser även positiva effekter av undervisningen.

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

The essay examines through semi-structured interviews the experiences of overcrowded housing, as they are portrayed through the eyes of children aged 8 ? 14. Overcrowded housing has an effect on children?s school performance, general health and is often linked to less capacity for normal social consumption. Yet there seems to be little done in terms of interrogating children about how they perceive their situation here and now.

The interactive whiteboard (IWB) is to be found in many classrooms in Sweden, and its number is growing rapidly. There is a lack of research of the use of the IWB in Sweden. The Swedish National Agency for Education refers to English research where the investment in the IWB in school is huge. In this study I will investigate how the IWB can be used as a mediating tool in the learning process. My study examines how interaction pattern appears when the teacher teaches with the IWB as a tool.

Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

This essay ventilates the relatively new phenomenon employer branding. Due to societal changes, such as demographical and financial changes, the labour market in Sweden has changed. It is evident that an increasing number of organisations need to put more of an effort in their methods of attracting talent and retaining competence within the organisation. By a case study based on five interviews, the purpose of the study was to compare literature and practice to see how well they compare as well as how employer branding bring about different aspects of the effect. There was also an ambition to highlight aspects of employer branding considered important to have in mind when undertaking an employer branding exercise.

Due to historically low prices for electricity in Sweden, many small-scale hydropowerplants were closed down. A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

The purpose of this master thesis was to study the librarians?assignment at the public accesses computers, especially howthe librarians perceive what their task is and what their taskshould be.In order to answer these questions a series of ten qualitativeinterviews ?inspired by the phenomenographic approach ?was conducted with librarians who were employed at smallpublic libraries in municipalities with 5 000 - 25 000residents in Sweden.The conclusions in the master thesis were that librarianshave both similarities and differences in how they perceivetheir tasks at the public computers. The most essential taskwas helping the user with information seeking. Thelibrarians also perceived that it should be included in theirduties to help users with the technical/practical issues at thepublic computers. Competence, time and assets were finallythree outlying factors which affected in what extent thelibrarians were able to help the users..
