Saccharomyces cerevisiae produces ethanol efficiently from the hexose sugars in lignocellulose hydrolysates, but it can not utilise pentose sugars such as xylose and arabinose. Stable xylose-utilising S. cerevisiae strains obtained by integration of the Pichia stipitis genes encoding xylose reductase (XR), xylitol dehydrogenase (XDH) and xylulokinase, exhibit low ethanol yields when utilising xylo

Popular Abstract in Swedish Glukos är kroppens viktigaste energikälla och distribueras via blodet. Hjärncellerna är helt beroende av glukos för sin energiförsörjning. Nervceller har dålig förmåga att lagra glukos och låga blodsockerhalter påverkar negativt dessa cellers funktion och kan ytterst leda till koma och död. Det är därför inte förvånande att blodsockerhalten normalt hålles inom ganska snAbstract The electrophysiological properties of insulin-secreting b-cells, glucagon-releasing a-cells and somatostation-producing d-cells in intact mouse pancreatic islets were investigated using the perforated patch whole-cell technique. It is demonstrated that it is possible to functionally identify the different cell types in situ. The ?-cells have a cell capacitance of 7.4 pF and differ from

Despite rigorous efforts to improve the construction working environment in the European Union, the fatal accident rate is approximately 13 workers per 100,000 as against 5 per 100,000 for the all sectors average. Although the accident rates have declined steadily and steeply since 1994, it still remains unacceptably high. Thousands of construction workers still suffer severe injury and even death

Packaging and the role it plays in supply chain efficiency is overlooked in most design and development research. An opportunity exists to meet the needs of supply chains to increase efficiency. This research presents three propositions on how to reduce the gap between supply chain needs and satisfaction in interaction with the product and packaging system. It also proposes a supply chain focused

A constantly growing intercontinental trade and modernization of transport infrastructure transformed the traditional patterns of carriage of goods globally. The majority of manufactured goods nowadays are transported in by sea in containers; however, transportation by land precedes and follows the sea carriage. These developments have created the preconditions for the development of multimodal tr

In this paper unequal error-correcting capabilities of convolutional codes are studied. State-transition graphs are used for investigating the error-correcting capabilities for specific inputs or outputs of given convolutional encoding matrices. Active burst input- and output-distances are defined and shown to be generalizations of the active burst distance. These new distances provide better esti

This article discusses the rise of the global anti-corruption "industry" with its elements of international campaigns and conventions, the traffic in project funds, people, knowledge and ideas, and how global structures interact with the local politics of anticorruption. The metaphor of landscape is utitilized to show the different perspectives -- global summits and local sites -- how anticorrupti

Det finns goda skäl till att engagera studenterna i deras egen bedömning vid både formativ och summativ examination. Vi har under kursen Molekylär Cellbiologi för Ekosystemvetare vid LTH undersökt studenternas förmåga att bedöma muntliga projektredovisningar och jämfört den med lärarnas. Under kursen genomförde studenterna ett projekt där en muntlig gruppredovisning med efterföljande kamratdiskuss
