Popular Abstract in English Colors have always been part of human life and culture. Today natural pigments have been substituted by synthetic dyes that usually end up threatening nature itself by polluting the environment. To what extent can we use chemistry and biology to minimize the environmental impact of the textile industry? During the dyeing process a certain amount of dye, 2 to 50 percent,Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. New technologies have been developed in the last decades and in particular Advanced Oxidation Processes (AOPs)

The importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in various systems and industries. Stud bolts are manually welded onto the heat exchanger surface in their manufacturing process. A project to fully automate this process using an indust

Development is often looked upon in economical terms and often research tries to investigate how one country can produce or sell more in order to increase its GDP. This thesis does not exclude these considerations but focuses on health as an important aspect of development. I investigate why South Africans (SA) would place their lives at risk with full knowledge of AIDS by not using freely availab

Popular Abstract in English You may have never heard of gas turbine engines, but they are used in all kinds of un¬expected places. For example, many of the helicopters you see, a lot of s¬maller power plants and even the military vehicle use gas turbines. A gas turbine consists of a compressor, a combustion chamber and a turbine. Air is taken into the compressor and mechanically compressed. It isIn gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). The massive cost involved with the machining of nickel alloys has driven continued research and development of cut

Problem description An organized approach to corporate real estate (CRE) decisions i.e. a CRE strategy, can add value to a company in many ways. The decision to own or lease real estate is a vital part of the strategy. What factors are decisions to own or lease CRE based on? The authors seek patterns in decision factors for different industries. Identified patterns will provide an understanding of

The aim of this study is to identify which types of international pressures can be found in Georgia’s democratization process and to understand how international pressures and external factors promote democratization of Georgia, using a theory-testing process tracing method. An analytical framework consisting of four types international pressures; contagion, control, consent, and conditionality is

In this report the characteristics of the electron applicator system for an Elekta SLi Plus linear accelerator have been studied. The investigation will serve as a basis for a new applicator design that will give less radiation leakage. The present applicator system does not fully comply with the recommendations of the International Electrotechnical Commission (IEC) Standards recording radiation l

The prevalence of metabolic diseases such as type 2 diabetes mellitus (T2DM) is rapidly increasing all over the world. Frequent episodes of elevated postprandial blood glucose have been associated with oxidative stress and subclinical inflammation, and the importance of a tight glycaemic control has been identified as an important factor to maintain health and prevent T2DM, obesity and cardiovascu

Complex space components are getting more important as the request for high precision space missions is increasing. The main contribution to vibrations on a satellite is the reaction wheels, the primary actuator in the attitude control of the satellite. One of the main sources of vibrations is torque ripple which is caused by various reasons, one being the control algorithm. This thesis focuses on

Popular Abstract in English Look around and notice how many items have been manufactured or transported using petroleum-based products. In modern life, it is almost an impossible task to exclude them from our daily routine. They are present in plastics, cosmetics, cleaning products, medicaments, food, etc. To diminish our dependence on the demanded black liquid, a lot of research efforts have beenDepletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. Efficient processes for the conversion of pla

Thesis Purpose: Purpose of this thesis is to explore consumer perception of innovation in grocery retail products in Sweden. Particularly focusing on how consumers perceive innovation within private label and manufacturer brands. Methodology: Qualitative analysis has been conducted through semi-structured interviews in order to understand consumer perceptions towards innovation in grocery sector i

We've long focused on the green transition, discussing various systems emphasizing the technical aspects of transitioning our lives. Yet, as many people experience anxiety about climate change, other, more existential perspectives are rising to the surface. Questions such as What is a good life? becomes more pressing as we begin to feel the effects of climate change also in our part of the world.

The possibility to integrate sustainability considerations in the public procurement process has been debated over recent decades, resulting in several legislative changes. Collaboration between public and private sectors is emphasised as important in the development of sustainable public procurement but few studies focus on public-private collaboration related to sustainable public procurement.
