A bench-scale unit for the development of an enzymatic process for the bioconversion of lignocellulosics to ethanol has been used to study the recycling of waste-water streams to minimize fresh-water requirements and reduce effluent streams. Willow, after impregnation with sulphur dioxide, was steam-pretreated, enzymatically hydrolysed, and the sugars produced were fermented using S. cerevisiae. T
Background-Considerable variability exists in the use of pharmacological thromboprophylaxis among acutely ill medical patients, partly because clinically relevant end points have not been fully assessed in this population. We undertook an international, multicenter, randomized, double-blind, placebo-controlled trial using clinically important outcomes to assess the efficacy and safety of daltepari
Experience curves are used to analyse the prospects for diffusion and adoption of renewable energy technologies, with special emphasis on wind turbines and photovoltaic (PV) modules. The analysis shows that the possibility of cost reductions of renewable energy technologies is greater than for conventional energy technologies. However, large investments are necessary to make wind turbines and PV m
An approach to teaching calorimetry is offered through practical, versatile undergraduate experiments using an isothermal heat conduction calorimeter, which measures a variety of heat changes--enthalpies of phase changes, hydration, dissolution, adsorption and desorption, and reaction--as well as the metabolic rate of living organisms. Isothermal heat-conduction calorimetry is contrasted with adia
Agriculture in many African countries is characterised by large diversity in production and great variation in growing conditions, irrigation potential and access to markets. This variation has proved to be a difficult matter when adjusting national agricultural policies and development projects to local conditions. In the face of the recent trend of less support for agricultural extension servic
Introduction: Biokinetic and dosimetry studies in small animals often precede clinical radionuclide therapies. As in human studies, a reliable evaluation of therapeutic efficacy is essential and must be based on accurate dosimetry, which must be based on a realistic dosimetry model. The aim of this study was to evaluate the differences in the results when using a more anatomic realistic mouse phan
Efficient variability management is a key issue in large-scale product line engineering, where products with different propositions are built on a common platform. Variability management implies challenges both on requirements engineering and configuration management. This paper presents findings from an improvement effort in an industrial case study including the following contributions: problem
When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat
Projects often suffer from lack of logistics considerations in the early phases. Since logistics is not the main focus of the people involved in the project, logistics solutions become reactive rather than proactive. With the increasing global competition, forcing companies to shorten time-to-market for their projects and becoming more cost effective, it becomes increasingly important to manage pr
Colonialism’ and ‘decolonization’ have been dealt with by postcolonial studies and, more recently, by scholars identified with the ‘de-colonial turn’. At the same time, in the ethnopolitically charged context of contemporary Bolivian society, colonialism and decolonization have become issues of political, existential and even cosmological import. This thesis identifies a need to root the ‘de-colon
The partitioning of 10% (w/w) lactic acid in ethylene oxide propylene oxide (EOPO) random copolymers and dextran T500 aqueous two-phase systems was studied. An analysis of variance design was applied to investigate the effect of pH, polymer concentration, and addition of polyethyleneimine to the aqueous two-phase systems. The lowest lactate partition coefficient of 0.09 was obtained at pH 6 in the
Artikeln diskuterar en föga uppmärksammad paradox inom etiken: Etiska teorier söker övervinna moralisk oenighet och bristande efterlevnad, men de lever på sitt misslyckande att åstadkomma detta. Om alla skulle handla efter universellt accepterade moraliska principer blev moralen ointressant. Kontraktsetiska teorier kan bidra till att förstå denna aspekt av etiken. Enligt dessa uppstår etiska probl
