Full-scale ethanol production from spruce has been evaluated, mainly from an energy perspective, using an Aspen Plus-model including all major process steps. The model input was based on data recently obtained on lab scale or in a process development unit. A number of different process configurations are presented in order to demonstrate how heat integration within the ethanol process significantl

We investigate a model for buffer management of multi-class traffic into a finite shared buffer. A hierarchy of increasingly stronger linear programming relaxations for this model is proposed. The number of hierarchies equals the number of job classes. Each relaxation in the hierarchy is constructed by projecting the original achievable performance region into a polytope with fewer variables and f

Popular Abstract in English Our exploitation of yeasts, dating back to the Neolithic period, in fermented and baked foods remains deeply routed in societies due to their cultural and economic importance. Due to the long intimate relationship with yeasts, Saccharomyces cerevisiae, the “baker’s yeast” remains the organism of choice. However, there is an enormous biodiversity of other yeasts, termed Abstract: For millennia, the “yeast” Saccharomyces cerevisiae remains by far the most extensively studied and exploited yeast in food and industrial applications. A number of researches and developments have been done since the establishment of the biochemical function of yeast by Louis Pasteur in 1860, however modern lifestyles often connected to food related health trends demand new and innovati

Bytecode folding is an effective technique for speeding up execution in Java virtual machines. This paper investigates a hardware implementation of the aforementioned technique on BlueJEP, a Java embedded processor. Since BlueJEP is a micro-programmed stack machine, we adopt a micro-instruction oriented approach, folding up to four microinstructions (corresponding to up to four bytecodes, on occas

In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

BACKGROUND: Knowledge is limited regarding the association between stem cells in histologically benign breast tissue and risk factors for breast cancer, and hence we addressed this issue in the present study. Recently, we assessed the histology of benign breast tissue from cancer and non-cancer patients for cells positive for the putative stem cell marker aldehyde dehydrogenase 1 A1 (ALDH), and th

Bone marrow (BM) contains a rare population of mesenchymal stromal cells (MSCs), which have been characterized as nonhematopoietic skeletal progenitor cells with central importance for the hematopoietic microenvironment. Classically, MSCs are isolated by plastic adherence and subsequent culture. However, as cultured stromal cells differ from their in vivo progenitors, it is important to identify t

As a by-product of a meeting between my university’s vice-chancellor and the manager of the largest bank in the small southern town of Ystad in 2006, I, almost accidentally, soon after came to commence teaching and researching media production, production studies, media industries studies or film and media industry studies, as the subject finally came to be called at Lund. The teaching part involv

The evaluation of emergency, disaster and crisis management exercises supports both individual and organisational learning, facilitates the development of response capabilities, and helps to determine whether the current level of preparedness is good enough. Nevertheless, despite its importance in the field of disaster risk management, there is a lack of a comprehensive overview of research in the

Background: Forensic psychiatric patients present a challenge as they manifest severe mental disorders together with criminal behaviour. There are well-known risk factors for criminal behaviour in the general population, yet knowledge of what predicts reconviction in the Swedish forensic population in the long-term perspective is still insufficient. Aims: The study aims to (1) describe background
