In order to make the hydrogen economy fully sustainable, renewable resources have to be employed for its production. Simulation models, developed with Aspen Plus to calculate mass and energy balances, will be used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. The main challenge is the reduction of water and heat demand connected t
This guideline for the investigation and initial treatment of atypical hemolytic uremic syndrome (HUS) is intended to offer an approach based on opinion, as evidence is lacking. It builds on the current ability to identify the etiology of specific diagnostic sub-groups of HUS. HUS in children is mostly due to infection, enterohemorrhagic Escherichia coli (EHEC), Shigella dysenteriae type 1 in some
The aim was to explore patients' experiences of information and their information needs after discharge for colorectal cancer surgery.
Fermentation of biomass residues and second generation biomasses is potentially a way to enable a sustainable production of hydrogen. Simulation models which calculate mass and energy balances, developed with Aspen Plus (R), are used to integrate the process steps necessary to produce pure hydrogen from biomass in a 2-stage fermentation process. Process and heat integration are introduced to reduc
A single antenna based virtual antenna array at the receiver can be used to find direction of different incoming radio signals impinging at the receiver. In this paper, we investigate the performance of random 3D virtual antenna arrays for DoA estimation. We have computed a Cramer-Rao Lower Bound (CRLB) for DoA estimation if the true antenna positions are not known, but these are estimated with an
Background: Neutralizing antibodies provide markers for vaccine-induced protective immunity in many viral infections. By analogy, HIV-1 neutralizing antibodies induced by immunization may well predict vaccine effectiveness. Assessment of neutralizing antibodies is therefore of primary importance, but is hampered by the fact that we do not know which assay(s) can provide measures of protective immu
Abstract in UndeterminedThis paper addresses the failure of activation programmes to achieve a rapid return to work when they are directed towards the long-term ill. The empirical basis for the paper is an analysis of the outcomes for 691 individuals in Sweden chosen for a re-activation policy programme to shorten their sick leave and increase their chances of returning to work. The outcome at the
The ambition to be recognized as a 'World City' or 'Global City' is rapidly increasing not the least among cities in the global south such as Hyderabad in India and Johannesburg in South Africa. While such a status seems promising for attracting foreign capital and for expanding the economic potential of urban areas, it may have adverse impacts on the hinterland and contribute to growing urban ine
This report describes the methodology for performing a quantitative risk analysis for a unidirectional road tunnel. By using representative accident scenarios, a basic queue model and performing an evacuation analysis the amount of casualties for each scenario can be estimated. By using the described methodology it gives the decision-makers a good idea of the risk level in the tunnel. The results
South East Asia, and Thailand in particular, are experiencing rapid population ageing. In Thailand older people are increasing in both proportion of the population and absolute number. Adaptations are needed to support this ageing population and to prevent poverty in old age. Since 2009 Thailand has had a minimum universal social pension, the Old Age Allowance (OAA) for all citizens aged 60 and ov
Issue of study: The plastic injection moulding industry has become highly competitive in terms of lead times and pricing, following an increase in low-cost manufacturing from Asia, as a part of the full supply chain. To remain competitive, mould tool manufacturers are looking to complement new tool manufacturing with local after-sales services in countries where their mould tools are being used. U
In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta
This thesis investigates the effect of commuting time on labour supply using US household survey data. To circumvent biased estimates as working hours and commuting time are jointly determined by the worker, a first differences approach is carried out, in which changes in the commute are assumed to be exogenous. The estimates suggest that there is no causal effect on labour supply that can be deri
Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. Here we investigate an alternative scenario, that is whether this proposed planet can exert observable perturbation on Main Belt astero
