The aim of the work presented in this thesis is the improvement of xylose fermentation performance of recombinant Saccharomyces cerevisiae strains expressing XYL1 and XYL2 from Pichia stipitis, encoding xylose reductase (XR) and xylitol dehydrogenase (XDH). A recombinant strain of S. cerevisiae, fermenting both xylose and glucose to ethanol could decrease the production cost of ethanol from ligno-

Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. There is a need to understand how the smooth muscle of the intestine and bladder can interact when brought into close contact surgically,

The Discrete Wavelet Transform (DWT) is a new way to analyze gas flow measurements in engine cylinders. The DWT technique differs significantly from the Fast Fourier Transform (FFT) in that with the former, the analysis of information can be done in both the time domain and frequency domain. The basic theory of wavelets is presented and the use of DWT is demonstrated on information derived from la

The purpose is to provide a brief overview of activities related to biofuels for transport in the Asia-Pacific Region, which covers a diverse range of countries and economies. The focus is on the Asia-Pacific Economic Cooperation (APEC),which is the premier forum for facilitating economic growth, cooperation, trade, and investment in the Asia-Pacific Region. APEC provides a forum for cooperation o

Otillräckligt blodflöde till hjärnan (cerebral ischemi) uppträder vid en rad kliniska tillstånd, exempelvis slaganfall (stroke), hjärtstillestånd och gravt sänkt blodtryck. Hjärnskador till följd av våld mot huvudet (traumatiska hjärnskadIschemic and traumatic brain damage are major causes of disability and death. While much effort has been spent to develop pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. Neuronal death following ischemia and trauma occurs in selected cell populations of the brain at various time points after the insult. It is believed that death of neurons are in part

In an exploratory investigation of personality patterns, Swedish air force pilots (n = 22) and ground officers (n = 14) were tested with the Creative Functioning Test, the Serial Color Word test, and the Spiral After-Effect Technique. The participants also answered open questions about their work and about creativity related items. Achievement ratings were made by their superior officers. An initi

Data from 3 whole body manikins, 2 babies and an adult, were used in the study. All the manikins used the same computer program and similar measuring and control units. No special measurements were made for baby and adult manikin comparison, but available data from earlier measurements was used. The conditions involved air layer insulation measurements (AL), laying on back on an insulating surface

Switched capacitors are here investigated for use in reconfigurable matching networks, particularly for DVB-H frequencies. A $0.13$ $mu$m CMOS circuit is evaluated through both simulations and measurements. Source grounded NMOS transistors are used to switch high quality metal capacitors located above metal layer 8. The quality factor and tuning range depend on frequency, switch voltage, capacitor

Mass spectrometry was used to determine the endotoxin (lipopolysaccharide, LPS) marker 3-hydroxytetradecanoic acid and 3-deoxy -D-manno-2-octulosonic acid in cigarette tobacco and smoke particles. Tobacco from cigarettes of different brands purchased in four different countries in Europe and Asia contained similar amounts of LPS. Indoor exposure to environmental tobacco smoke (ETS) in rooms of smo

Popular Abstract in Swedish Vid diabetes råder en oförmåga att hålla nere blodsockret, i synnerhet efter en måltid. Under normala förhållanden orsakar en höjning av blodsockret att insulinfrisättningen stimuleras. Insulin ökar upptaget av glukos i vävnaderna i kroppen, vilket sänker blodsockret. Under vissa förhållanden, såsom fetma, minskar effekten av insulin, ett fenomen som även kallas insulinThe parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP). Exogenous administration of either GRP or PACAP ha
