AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

The aim with this paper is to study Karl Popper?s view on realism and relativism. Further aim is to see whether those ideas have been consistent over the years. The paper argues that Popper since his first interest in philosophy has taken a realistic and antirelativistic attitude. Only his arguments for this position have been developed to meet his critics.Common sense speaks for realism but can neither be proven nor refuted.

Tripeptidyl peptidase II (TPPII) is an exopeptidase which cleaves tripeptides from theN-terminus of peptides. The exact functional role of TPPII is still a matter of investigation. Itis believed that the enzyme is primarily involved in intracellular protein degradation, where itcooperates with the proteasome and other peptidases to degrade proteins into free aminoacids. These amino acids can subsequently be used in the production of new proteins. The aimof this work was to express murine wild type TPPII using E.

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

This Degree Project is carried through in association with Fototext in Guthenburg. The firmsees benefits using?Soft Proof? technology for both economic and time-saving. The reasonfor ?Soft Proofing? for internal/ external production is to estimate and controll documentswithout using digital or chemical printing output.The different technical solutions to ?Soft Proof?, knowledges and facts aboutColorManagement together with PDF-workflow is going to pattern for a correct succesfull?Soft Proofing? on the monitor.Acrobat 5 in association with Photoshop 6 are effectively used in ?Soft Proofing? technic.The advance and capacity of the graphical softwares which are explained in this reporthelps the users to begin to experiment with ?Soft Proof?.

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
