Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. The purpose of this work was to study the degradation of organic matter at WWTPs within two areas in particular; 1) d
Popular Abstract in English Figure 1: Electron microscopy image of mesoporous material seen from above. The left image shows a possible shape of a silica particle (scale bar: 1 μm). The right image shows the mesopores in the particle (grey color) with the silicon dioxide walls (black color) (scale bar: 150 nm). Poly(N-isopropylacrylamide) (PNIPAAM) is a polymer that can provide the active part forMesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). This work addresses the following issues. i) Surface grafted PNIPAAM was found to be loca
Power supply systems play a very important role in applications of everyday life. Mainly, for low power generation, there are two ways of producing energy: electrochemical batteries and small engines. In the last few years many improvements have been carried out in order to obtain lighter batteries with longer duration but unfortunately the energy density of 1 MJ/kg seems to be an asymptotic value
The fundamental question posed in this study is how to approach the construction sector in order to cover its wide scope of activities, its great variety of actors and the external influences on it from the market and institutional environment. Construction includes such diverse economic activities as new production and as repair/maintenance, itinerant production and stationary manufacture, the pr
The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. However, in lean combustion, problems related to the flame stability can arise. Swi
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. Both actin and tubulin were shown to copurify with PM vesicles and this copurificati
Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. The distribution of the molecules between these two sites
Today's handheld computing devices equipped with novel wireless network technologies can provide their users with features such as mobility, multimedia support and group communication. On the other hand, the administrative effort required to enable all these features increases beyond the level that an ordinary user can manage. Ad hoc networks, being able to quickly organise themselves without user
The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely
Abstract in UndeterminedUzbekistan, after gaining independence from the Soviet Union in 1991, had publicly declared that it would adhere to democratic governance principles in designing and implementing its public administration policies. As a newly-independent state with democracy claims, Uzbekistan had tried to establish new democratic institutions with an effort to capture international communi
Rising temperatures can influence ecosystem processes both directly and indirectly, through effects on plant species and communities. An improved understanding of direct versus indirect effects of warming on ecosystem processes is needed for robust predictions of the impacts of climate change on terrestrial ecosystem carbon (C) dynamics. To explore potential direct and indirect effects of warming
Prodatec is a Mexican company manufacturing office furniture and closets. As the competiveness increases there are higher demands on better quality. The company wishes to compete by heading towards a Lean Manufacturing system. The first step is to implement 5S as a natural corner stone in the production. There is also a wish to be ISO 9000 certified in the future. During autumn 2008 the autst hor
The emergent Social Media presents risks and opportunities for the brand that academic research still needs to reach further understanding (MSI, 2010). From both theoretical and managerial points of view, research is needed in regards to consumer created negative brand meanings in social media settings. Further, consumers have now the ability to share negative brand product evaluations at a massiv
In this paper, we carried out a systematic literature review to document the emerging scientific knowledge about COVID-19 impact on livestock systems and food security in developing countries to identify gaps and possible avenues for future research undertakings. Specifically, we systematically reviewed 68 peer-reviewed articles extracted based on rigorous selection criteria fromScopus, PubMed and
Background: In contrast to typical measures employed to assess outcomes in healthcare such as mortality or recovery rates, it is difficult to define which specific outcomes of care are the most important in caring for dying individuals. Despite a variety of tools employed to assess different dimensions of palliative care, there is no consensus on a set of core outcomes to be measured in the last d
In this paper we call into question the relationship between development, inequality and territory in the current context of globalization and within the framework of public policies designed, supposedly, to benefit those social actors with fewer resources. In order to do this, we focus on a case study in the northeast of the province of Misiones, Argentina. Here tobacco production, forestry and a
Quantitative nuclear medicine imaging is an increasingly important frontier. In order to achieve quantitative imaging, various interactions of photons with matter have to be modeled and compensated. Although correction for photon attenuation has been addressed by including x-ray CT scans (accurate), correction for Compton scatter remains an open issue. The inclusion of scattered photons within the
Induced polarization (IP) is an acknowledged method in ore exploration and can be applied to evaluate the metal content in dumps containing the residues of ore processing facilities. Existing models explain the relationships between ore content and grain size of the ore particles with IP parameters. However, the models assume full water saturation of the ore containing samples, which is often not
This thesis contributes to research on experimental and behavioral economics as well as auction theory. It consists of five papers.The first paper, Differences Attract: An Experimental Study of Focusing in Economic Choice, studies whether individuals' decisions are affected by focus effects. The focus effect suggests that individuals focus more on an attribute that has a larger difference among th
