Using three different laser systems, we demonstrate a convenient and simple plasma based diagnostic of the contrast of high-power short-pulse lasers. The technique is based on measuring the specular reflectivity from a solid target. The reflectivity remains high even at relativistic intensities above 10(19) W/cm(2) in the case of a high-contrast prepulse-free laser. On the contrary, the specular r
Granule neurons from the rat dentate gyrus were acutely isolated and whole-cell currents recorded. Maximal enhancement of 7 muM gamma-aminobutyric acid (GABA; EC30) evoked currents was obtained with 100 muM pentobarbital where the peak-current was 2.1 +/- 0.2 of control. One hundred muM pentobarbital alone evoked no current response whereas I mM pentobarbital elicited a current response that was 0
Purpose: Conventionally, the management of exocrine pancreatic insufficiency (EPI) involves the consumption of a specific diet as well as the replacement of pancreatic enzymes, the effectiveness of which is usually measured by a classical method of blood analyses of non-esterified fatty acids (NEFA) and triglycerides (TG). Dietary supplementation with a pancreatic enzyme preparation (PEP), in conj
Background: Increased fucosylation of serum,glycoproteins has previously been reported in patients with liver disease. We analyzed alpha(1)-acid glycoprotein (AGP) fucosylation in serum samples from patients investigated for suspected liver disease to evaluate its value as a biochemical marker for liver cirrhosis. Methods: We used a novel lectin immunoassay adapted to the AutoDELFIA system to anal
This study aimed at evaluating the possibility of predicting septicemia in burn patients by using wound surface and tissue culture techniques as well as blood cultures. Fifty patients with full-thickness burn wounds covering at least 10% of the total body surface area were included. Signs of septicemia were noted in 21 patients (42%) and 29 patients died (58%). The bacterial colonization of the bu
Surface complexation of orthophosphate ions at the water-suspended-and-aged gamma-Al2O3/water interface has been studied by means of a series of batch experiments in 0.1 M Na(Cl) medium at 25.0 degrees C in the range 4.8 < -log [H+] < 9.6. The ratio between phosphate concentration and concentration of surface active groups (=AlOH) was varied between 0.15 and 1.50. The suspensions were equilibrated
Popular Abstract in Swedish Detta arbete behandlar regleringen av arbetsgivarens arbetsledningsrätt och arbetstagarens arbetsskyldighet i svensk, engelsk och tysk rätt i ljuset av arbetslivets ökade flexibilisering. Arbetslivets flexibilisering handlar om att öka anpassningsförmågan och rörligheten, och beskrivs ofta som övergången från den traditionella anställningen till atypiska anställningar. The general aim of this doctoral thesis is to study the legal regulation of the managerial prerogative and how it relates to the employee’s obligation to work in Swedish, English and German law in the light of the increasing flexibilisation of working life. The ongoing flexibilisation of working life is often described as an increase in adaptability and allocative flexibility, and as a shift from
What is normally described as bias? A possible definition comprises attempts to distort or mislead to achieve a certain perspective, i.e. subjective descriptions intended to mislead. If designers were able to exclude bias from informing systems, then this would maximize their effectiveness. This implicit conjecture appears to underpin much of the research in our field. However, in our efforts to s
We compared three different molecular methods currently used for screening of Mhc variation in population studies of Atlantic salmon. Restriction fragment length polymorphism (RFLP) of the entire class II gene detected 22 haplotypes. Seventeen exon 2 sequences were obtained from individuals carrying the 22 haplotypes, two of which had not been detected by RFLP. The six alleles (27%) detected by RF
In this article, we present the results from photoconductivity measurements in the infrared spectral region (3-10 mum) on ensembles of self-assembled InAs quantum dots embedded in a matrix of InP. In the spectral distribution of the photocurrent, peaks are observed which we interpret in terms of transitions from the dots' ground- and first-excited states to the conduction band of the dots/matrix.
Silurian bentonites from Sweden and the eastern Baltic are correlated using XRD analysis of sanidine composition. Identifying the same bentonite in different sections has constrained correlations between the conodont, graptolite and chitinozoan zonations. Three bentonites correlate the Cyrtograptus murchisoni Zone with the upper part of the Pterospathodus amorphognathoides Zone and both the Lower
INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP)-induced pancreatitis (EIP) provides an opportunity to study different pathophysiologic events early in the course of acute pancreatitis. AIMS: To investigate whether the leakage of pancreatic proenzymes (anionic trypsinogen), pancreatic protease activation (carboxypeptidase B activation peptide), cytokine response (interleukin [IL
OBJECTIVE: Recent studies have found an increased risk for both anxiety disorder and attention-deficit hyperactivity disorder (ADHD) in the adult relatives of children with ADHD in comparison with adult relatives of normal controls. Such findings may account for the high rates of comorbid anxiety found in children with ADHD, and they suggest a relationship between the two disorders. However, addit
Polyamines are essential for tumor cell growth, and the polyamine pathway represents an attractive target for cancer treatment. Several polyamine transport proteins have been cloned and characterized in bacteria and yeast cells; however, the mechanism of polyamine entry into mammalian cells remains poorly defined, although a role for proteoglycans has been suggested. Here, we show that the HIV-Tat
Bream Abramis brama) undergo ontogenetic diet shift from zooplankton to benthic macroinvertebrates, but the switching size may be highly variable. To unravel under what conditions bream are pelagic versus benthic foragers, we experimentally determined size-dependent foraging capacities on three prey types from the planktivory and benthivory niche: zooplankton, visible and buried macroinvertebrates
In Sweden, clear changes in the care of the elderly have occurred during the 1990s, with fewer people being provided public care, although greater efforts are now directed towards those most in need of help. Elderly people are cared for increasingly in other ways: by the family, by means of market-provided care, and by voluntary and informal means. Differences between municipalities are considerab
The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time scale is based on various records from the DYE-3, the GRIP, and the NorthGRIP ice cores, the glacial part is solely based on NorthGRIP records. Here we present an 18 ka extension of the time scale such that GICC05
Post-traumatic Stress Disorder (PTSD) is a syndrome de®ned by the intrusive reexperiencing of a trauma, avoidance of traumatic reminders, and persistent physiological arousal. PTSD is associated with high levels of comorbidity and may increase the risk for additional disorders over time. While controversies remain regarding the applicability of the PTSD criteria to very young children, it has prov
