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

Only during the last two decades has the discourse on evaluation been on the Swedish agenda of social work and social care. One assumption is that a conscious need for evaluation knowledge and evaluation capacity has finally surfaced. This based on the view that work efforts of social service organizations are regarded as chiefly authority-based and to a lesser degree based upon scientific knowled

The empirical part of this study is based on a survey of 600 Swedish households and a number of interviews where questions about residential energy behaviour and possible policy instruments for change were raised. The study provides insight into current behavioural patterns and gives a bottom-up perspective on the realistic perspective potentials for change and ways to achieve them. Residential en

Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. An EM community in a phosphorus-poor forest was exposed to apatite and EM mycelia actively colonizing ingrowth bags were analyzed. Internal transcribed spacer (ITS)
