The starch industry is a key sector of the European food industry with an annual turnover of approx. €4 billion. The production processes in the starch industry are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs). Membrane processes are only rarely used. This presentation will show how membrane processes can be used to optimise
A novel set up composed of an anaerobic biofilm reactor followed by ozonation was used for treatment of artificial and real textile effluents containing azo dyes. The biological treatment efficiently removed chemical oxygen demand and color. Ozonation further reduced the organic content of the effluents and was very important for the degradation of aromatic compounds, as shown by the reduction of
Business Rules (BR) and Business Processes (BP) are essential pillars in any Business Information System (BIS) and important areas of BIS design (BISD). Historically, BRs have been overlooked as a part of BISD. The Business Rules Approach (BRA) focuses on concepts and methods to remedy the neglected BR design and management. BRs in this perspective are stateless and concerned with the “what” of a
Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f
Thin films of different derivatives of fluorinated alkyl phosphoric acids have been deposited from aqueous solutions onto surfaces of oxidized polycrystalline nickel stamps. which are commonly used in several industrial applications of nanoimprint lithography (NIL). The films have been established in order to increase the antiadhesion tendencies at the stamp polymer interface. Thicknesses, chemica
Popular Abstract in English Most people see chemistry as an abstract and complicated subject because it deals with species that can not be seen with bare eyes. But if one think about it, chemistry is everywhere! Chemical processes happen all around you and inside you everyday : there is chemistry in the human body where proteins play a great role, in shampoo bottles, the toothpaste, in the cement A considerable amount of mineral particles are found to have a plate-like shape. The work in this thesis concerns theoretical investigations, using Monte Carlo method, of the properties of such particles in aqueous solutions. The objectives were first to create a model that could capture the essential physics of clay suspensions and also to understand the role of thermodynamics in certain chemical
The main purpose of the recently introduced Bürger-Diehl simulation model for secondary settling tanks was to resolve spatial discretization problems when both hindered settling and the phenomena of compression and dispersion are included. Straightforward time integration unfortunately means long computational times. The next step in the development is to introduce and investigate time-integration
The built environment accounts for a significant share of energy consumption and energy efficiency in this sector is important for the Swedish environmental objectives. Only a limited share of the total new construction of multifamily houses are constructed as low-energy buildings. Current building regulations lay down requirements for energy efficiency for new construction, and these will be tigh
Issue: To create a supporting IT-tool for project management in an integrated product development process at global companies is a complicated task. The IT-tool must be embedded in the organisation, managing the information flow in a correct way, support the product development framework, be accepted and commonly used in the whole company. These aspects must be fulfilled if an IT-tool for project
For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. Dry powder inhaler (DPI) is today one of the most used inhalers for pulmonary delivery.
This article describes a logistics-based framework for organizational change of service organizations. This framework is based on the key concepts of modern logistics: systems thinking for a holistic approach to business; process orientation for structure of the organization; and process management for continuous change and improvement. The development of logistics as a research and practitioner d
Lactone flavors with fruity, milky, coconut, and other aromas are widely used in the food and fragrance industries. Lactones are produced by chemical synthesis or by biotransformation of plant-sourced hydroxy fatty acids. We established a novel method to produce flavor lactones from abundant non-hydroxylated fatty acids using yeast cell factories. Oleaginous yeast Yarrowia lipolytica was engineere
Future-oriented environmental assessments—in particular, prospective life cycle assessments (LCAs)—are increasingly applied within the wastewater treatment (WWT) sector. This thesis contributes to this field of research by addressing how to estimate the environmental impact (improving LCA methodology) and what the impact amounts to (WWT-specific results) for a wastewater treatment plant not yet co
