Analysis of Degradation Products from Wood and Methods for Detoxification of Lignocellulose Hydrolysates

Popular Abstract in Swedish Med dagens alla transporter finns det ett mycket stort behov av tillgång till billigt och miljövänligt drivmedel. Det bränsle som används i särklass mest är bensin framställd från råolja. Ett problem med bensinen är att den inte tillverkas från förnyelsebara råvarukällor. Detta innebär att när oljan tar slut så går det inte att tillverka mer bensin. Däremot är det idag In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. Several of these compounds might act as inhibitors during the fermentation of the sugars to ethanol. Thus, in order to obtain high etha

Enzymatic synthesis of acrylates. Catalyst properties and development of process and product

The increasingly apparent environmental problems in our surroundings necessitate a quest for sustainable development in all areas of human endeavour. Within the field of chemistry and the production of chemicals, the focus is increasingly on the development of green chemistry. This discipline aims to reduce environmental impact by replacing petrochemical raw materials with renewable feedstock and

ABSOLUTE QUANTIFICATION OF ACTIVITY CONTENT FROM PET IMAGES USING THE PHILIPS GEMINI TF PET/CT SYSTEM.

Positron emission tomography combined with computed tomography (PET/CT) is a quantitative technique suitable for diagnostics and uptake measurements. The quantitative results can be used for the purpose of the calculating absorbed dose to patients undergoing nuclear medicine investigations. Hence, the accuracy of the quantification of the activity content in organs or tissues is of great importanc

Endovascular techniques in acute arterial mesenteric ischemia.

Rapid developments in preoperative noninvasive imaging as well as advanced endovascular techniques have made endovascular treatment of acute arterial mesenteric ischemia a feasible treatment option in many patients. Multidetector computed tomographic angiography will provide the diagnosis and guide treatment in most cases. The use of mechanical and aspiration embolectomy, sometimes in combination

Comparing foreign accent and ”Rosengård Swedish”: some hypotheses and initial observations.

Within the research project ‘Language and language use among young people in multilingual urban settings’ (Lindberg 2004) my role is to describe SMG pronunciation, the pronunciation of ‘Swedish on Multilingual Ground’ (e.g. Rosengård Swedish). Thanks to means placed at my disposal by the Faculty of Humanities at Lund University, I am able to broaden my research field to include also a comparison o

QuikSCAT measurements and ECMWF wind forecasts - an explorative study

The aim of this paper is to study the covariance structure for the difference between satellite measurements and meteorological forecasts of near-surface ocean winds. This type of covariance enters in assimilation techniques such as Kalman filtering. I all, six residual fields are studied. Us of a Box-Cox transformation leads to approximately symmetrically distributed residual wind speed fields.

Novel and conventional biomarkers for prediction of incident cardiovascular events in the community.

CONTEXT: Prior studies have demonstrated conflicting results regarding how much information novel biomarkers add to cardiovascular risk assessment. OBJECTIVE: To evaluate the utility of contemporary biomarkers for predicting cardiovascular risk when added to conventional risk factors. DESIGN, SETTING, AND PARTICIPANTS: Cohort study of 5067 participants (mean age, 58 years; 60% women) without cardi

Being in charge of life: perceptions of lifestyle among women of retirement age.

Scand J Caring Sci; 2009 Being in charge of life: perceptions of lifestyle among women of retirement ageAim: The aim of this study was to describe the perceptions of lifestyle among women of retirement age. Background: Women go through many transitions during their lives, which impact on their lifestyle and possibly their outlook on life. Family circumstances such as motherhood and marital status
