A previously developed computational model for 3D finite element simulations of wood during moisture changes is in the present work provided with a special-purpose graphical user interface. The software is designed to use a personal computer for the graphical user interface and to have possibility to use distributed computational resources for the simulation.

Many street vendors live under constant fear of eviction and harassment because the law does not recognize their businesses and they work outside the rule of law. Furthermore, in some cities street vending is a criminal offence to public order and vendors can be sent to prison. Using the empowerment theory, defended by Hernando De Soto, this article will examine to what extent formalization - unde

The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet

BACKGROUND: Circulating prostate cells can be detected with a reverse transcription-PCR (RT-PCR) assay for prostate-specific antigen (PSA) mRNA. We have developed a new quantitative RT-PCR method for measuring PSA mRNA. METHODS: The method uses a PSA-like internal standard (IS) mRNA that is added into the sample at the beginning of the RNA extraction and coamplified by RT-PCR with the PSA in the s

The acoustic field in an annular gas turbine combustion chamber with thirty burners has been studied using a hybrid approach. The acoustic field was determined by solving an inhomogeneous wave equation. The acoustic sources were provided by a low Mach number flow solver. The main focus was to determine the influence of nonuniform behavior and interactions of neighboring burners. For this reason th

Objective: Varying degrees of inter-organizational collaboration concerning children at risk has grown rapidly since the 1980s. Collaboration is understood to provide a more holistic view of the child’s needs, lead to better care and treatment, more efficient law enforcement as well as increase knowledge in general. The aim of this presentation is to explore processes and effects, by highlighting

Policy intervention schemes for increased deployment of solar photovoltaics (PV) have been launched in several countries, with varying success. In order to ensure an efficient deployment of the technology, thorough knowledge is needed about relevant present actors and institutions, and about how a desirable actor base and institutional setup should look like; mere cost reductions are not enough to

Using a system analysis approach compares different systems for handling and treatment of toilet waste and organic household waste. Design issues considered are source separation of urine, use of vacuum toilets and advanced nutrient recovery processes such as Reverse Osmosis (RO). All of the studied systems have low emissions of eutrophy ing compounds. Other environmental effects are mainly relate

The use of Commercial-off-the-Shelf (COTS) software has become more and more important in state-of-the-art and state-of-the-practice software and system development. The use of COTS software promises faster time-to-market, reduced development cost, increased productivity, and the possibility for companies to focus on their own core competencies. At the same time COTS software raises risks such as
