Controlled pilot development unit-scale fed-batch cultivation of yeast on spruce hydrolysates

Yeast production on hydrolysate is a likely process solution in large-scale ethanol production from lignocellulose. The hydrolysate will be available on site, and the yeast has furthermore been shown to acquire an increased inhibitor tolerance when cultivated on hydrolysate. However, due to over-flow metabolism and inhibition, efficient yeast production on hydrolysate can only be achieved by well-

Laser Doppler flowmetry during hyperaemic reactions in the skin

Laser Doppler flowmetry (LDF) was used to study skin blood flow in the finger tip and on the dorsum of the hand in healthy volunteers. Vasodilatation in the finger tip was induced by immersing the arm in water at 42 degrees C, and vasodilatation in the dorsum of the hand by intracutaneous injection of dihydralazine. Simultaneous measurements were performed using venous occlusion plethysmography (f

Closure after gastrostomy button

A gastrostomy device is removed from the gastrostoma when no longer needed. The aim of the study was to test the hypothesis of whether it is possible for the surgeon to decide which stoma has to be closed with a gastroraphy and which to leave for a spontaneous closure within a reasonable period of time. Out of a cohort of 321 patients, who had been operated with a video-assisted gastrostomy, we in

On the allophonic behaviour of German /x/ vs /k/ - an EPG investigation

Facts about the phonotactics and the allophonic behaviour of German /x/ vs /k/ are summarized and discussed concerning the question of categorical vs gradual assimilation. It is concluded that the different allophonic variation of /x/ vs /k/ can more appropriately be described in terms of a difference in articulatory control rather than in assimilation. This difference is associated with a stronge

Persistent spectral hole burning from oxygen-evolving Photosystem II cores from cyanobacteria and higher plants

Persistent spectral hole burning was performed on active Photosystem II (PSII) cores from spinach and Synechocystis 6803, each containing about 32 chl a molecules per core. Hole-burning action spectra are presented. The data appear inconsistent with a mechanism involving non-photochemical hole burning, as has previously been observed in isolated PSII protein-pigment fragments. A photochemical hole

Managing pain in older persons who receive home-help for their daily living. Perceptions by older persons and care providers

Pain is a common problem for older persons who need professional help for their daily living. In this study 94 older persons (75+) in persistent pain were compared with 52 care providers concerning the pain management methods they had used/administered during the previous week and how helpful they perceived these methods to be. interviews were based on 16 items from the original version of the pai

3-D Monte Carlo-based scatter compensation in quantitative I-131SPECT reconstruction

We have implemented highly accurate Monte Carlo based scatter modeling (MCS) with 3-D ordered subsets expectation maximization (OSEM) reconstruction for I-131 single photon emission computed tomography (SPECT). The scatter is included in the statistical model as an additive term and attenuation and detector response are included in the forward/backprojector. In the present implementation of MCS, a

Crank Angle Resolved HC Detection Using LIF in the Exhausts of Small Two-Stroke Engines Running at High Engine Speed

In order to separate the HC-emissions from two-stroke engines into short-circuit losses and emissions due to incomplete combustion, Laser Induced Fluorescence (LIF) measurements were performed on the exhaust gases just outside the exhaust ports of two engines of different designs. The difference between the two engines was the design of the transfer channels. One engine had "finger" transfer chan

Systematic Studies of N IV Transitions of Astrophysical Importance

E1, M2, M1 and E2 rates of transitions between n = 2 levels of N IV have been calculated using the tw independent codes CIV3 and MCHF. Convergence of each of the approaches has been studied and comparisons made as the complexity of the calculations increases to include valence, core-valence and core-core correlation. The agreement between the two methods is sufficiently good to allow us to set qui

Classification of traveling waves for a class of nonlinear wave equations

We classify the weak traveling wave solutions for a class of one-dimensional non-linear shallow water wave models. The equations are shown to admit smooth, peaked, and cusped solutions, as well as more exotic waves such as stumpons and composite waves. We also explain how some previously studied traveling wave solutions of the models fit into this classification.

Farvatten och blindskär i barnhabiliteringen. Examinationspaper från en påbyggnadsutbildning

Rapporten bygger på examinationspaper från en påbyggnadsutbildning för 29 praktiker inom Barn- och ungdomshabiliteringen i Sverige, som genomfördes under 2001–2002 av en nationell arbetsgrupp från aktörer inom barnhabiliteringsfältet. Som examination på kursen skrev deltagarna en reflektion över en aspekt av sin praktiska vardag, där denna problematiserades i termer av sin relationella, sociala, o
