The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Background: Employees acting towards company goals and having a strong desire to remain in the organisation are very important for the success of a company. In order to generate such organisational commitment of the employees, the knowledge about what motivates and satisfies them is essential. Purpose: The purpose of this thesis is to investigate and analyse the factors which motivate employees, under consideration of individual characteristics. Limitation: Age, gender, marital status, work area, position and the years a person has been working in the company represent the individual characteristics examined in this study. Realisation: Literature research as well as a practical survey consisting of mail questionnaires and personal interviews were carried out in order to best serve the purpose of this thesis.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

ITT Water & Wastewater (före detta ITT Flygt) tittar på att eventuellt genomföra en förbättring av ytbehandlingen av deras pumpar för att eliminera de rostangrepp pumparna utsätts för idag. Examensarbetets uppgift är här att analysera och beskriva miljöeffekterna av de nya ytbehandlingsmetoderna som företaget undersöker.Målet med studien är att få fram ett underlag och en rekommendation om vilken ytbehandlingsmetod företaget bör välja ur miljösynpunkt.De olika metoder som studerats är:? Järnfosfatering + ED-lackering? Zinkmanganfosfatering + ED-lackering? Oxsilan + ED-lackeringDessa metoder har jämförts med nollalternativet, vilket innebär att samma metod som tillämpas idag fortsätter att användas.Miljöeffekterna som studerats för de olika metoderna är:? utsläpp till luft och vatten? avfall? energiAv de tre nya metoderna samt nollalternativet är Oxsilan följt av ED-lackering det alternativ som ger minst påverkan på miljön. Metoden har inga utsläpp av flyktiga organiska ämnen till luft, inget farligt avfall bildas och det avfall som ändå bildas är litet. Metoden har även lägre energiåtgång än de andra studerade metoderna.2008:Nr 2 Teknik.

AbstractThe purpose of this bachelor thesis is to investigate whether Skatteverket?s interpretation of 3:9 and 3:10 IL is consistent with the legislator?s purpose with these rules.The bachelor thesis is written with a legal approach which seeks to use all sources of law in accordance to its legal source value.Individuals who are considered as tax residents in Sweden have the opportunity to be granted tax exemption according to the six-month-rule and the one-year-rule if the individual works abroad. If the income is taxed in the country of source and the individual has been working there for more than six months, the six-month-rule can be applicable. If the income has not been taxed in the country of source, the individual still can be granted tax exemption through the one-year-rule, but to do so he has to work in the same country for at least one year. Both rules require that the individual does not visit Sweden more than 72 days in a time span of one year.Skatteverket has, in its consideration, decided to add the 72 days on which an individual can visit Sweden with a new number of days, 24 days, which individuals can visit third countries.

Fartyg använder sig av stora dieselmotorer för framdrift och för att producera elektricitet ombord. Motorerna samt diverse kringsystem har behov av kylning och till detta används kemikaliebehandlat vatten i ett slutet kylsystem. Vid tömning och läckage från systemet tenderar det kemikaliebehandlade vattnet att hamna med länsvattnet. Länsvattnet genomgår en reningsprocess innan det pumpas överbord. Denna reningsprocess är inte utformad för att avskilja kemikalier och dessa tenderar att hamna i havet.

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

The foundations of the Swedish labour market have shifted due to a number of new circumstances affecting its framework. Employment is no longer a right taken for granted but rather something one should work hard to achieve. Given the new conditions, employers are not only trying to ensure their own businesses survival but also uphold the structures of our society. Competition between enterprises forces management to forge new boundaries to maintain profitability.Concerns have arisen whether or not these so called management strategies are within the limitations of the law. As a result and as a response to the design of the labour laws creativity is peaking to overrun the statutory regulations.

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

This bachelor?s project deals with both the problems of high water temperatures in fishponds at a fish-breeding station and of the nutrient load to nearby lakes and streams in Harasjömåla, Blekinge, Sweden. Theory, methods and results of the analyses are presented in the report..
