RF and DC characterization of vertical InAs nanowire MOSFET on Si substrates are presented. Nanowire arrays are epitaxially integrated on Si substrates by use of a thin InAs buffer layer. For device fabrication, high-k HfO2 gate dielectric and wrap-gates are used. Post-deposition annealing of the high-k is evaluated by comparing one annealed and one not-annealed sample. The annealed sample show be
This biweekly commentary in an Austrian online newspaper presents my reflections upon Bolivian society and politics
Due to political conflicts, the northern part of Cyprus is being under economical crisis. This is employed by environmental problems such as non-organised improvement of residential areas and their effects on habitat. Especially, three main cities where 75 percent of population is crowded, is seriously under the threat of sewerage problems. In this study the comparisons for available sewerage syst
I denna studie analyseras potentialen för en ökad tillförsel av biomassa från skog, jordbruk och akvatiska system i Sverige baserat på en sammanställning och bearbetning av aktuella potentialstudier. Analysen inkluderar tekno-ekonomiska begränsningar och minimering av risker för miljömålskonflikter vid en ökad produktion av biomassa. Dessutom analyseras potentialen för en ökad avsättning av biomas
Therapy directed against oncogenic FLT3 has been shown to induce response in patients with acute myeloid leukemia (AML), but these responses are almost always transient. To address the mechanism of FLT3 inhibitor resistance, we generated two resistant AML cell lines by sustained treatment with the FLT3 inhibitor sorafenib. Parental cell lines carry the FLT3-ITD (tandem duplication) mutation and ar
Organizational problem spaces can be viewed as complex, uncertain and ambiguous. They can also be understood as open problem spaces. As such, any engagement with them, and any effort to intervene in order to pursue desirable change, cannot be assumed to be just a matter of ‘complicatedness’. The issue is not just a need to cope with dynamics of system. It is also the perceptual ‘boundedness’ of mu
Convection is shown in earlier studies to improve the thermal contact between heat exchanger and borehole wall in water-filled boreholes. This study investigates the effect of convection on the required borehole length for a ground-coupled heat pump installation. Artificial convection was induced by an ordinary groundwater pump during a multi-injection rate thermal response test (MIR-TRT). For com
Study Design Controlled laboratory study; cross-sectional. Background Postural control following anterior cruciate ligament reconstruction (ACLR) primarily has been investigated during static single-leg balance tasks. Little is known about dynamic postural control deficits post-ACLR. Objectives To compare dynamic postural control (bilaterally) in persons who have undergone ACLR and healthy control
Type 1 (T1D) and type 2 (T2D) diabetes share pathophysiological characteristics, yet mechanistic links have remained elusive. T1D results from autoimmune destruction of pancreatic beta cells, whereas beta cell failure in T2D is delayed and progressive. Here we find a new genetic component of diabetes susceptibility in T1D non-obese diabetic (NOD) mice, identifying immune-independent beta cell frag
BACKGROUND: Preterm birth remains the major risk factor for the development of intraventricular hemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular hemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Antithrombin, a glycoprotein synthesized in the liver, is the major plasma inhibi
Objective To compare long-term work loss in methotrexate-refractory early rheumatoid arthritis (RA) randomized to addition of infliximab or conventional combination treatment. Methods Multicentre, two-arm, parallel, randomized, active-controlled, open-label trial. RA patients with <1y symptom duration were recruited from 15 rheumatology clinics in Sweden between 2002-2005. Patients who did not ach
Several commercial UF-membranes are characterized by water contact angles. Two different methods of contact angle measurements, the sessile drop and the captive bubble methods, are compared. Differences in results between the two methods occur for the DDS GR 61 membrane; otherwise the methods give rather consistent results. The advancing and the receding contact angles are measured for the UF-memb
A rheological method for screening water soluble polymers intended for fouling prevention of membranes is investigated.Viscosity is measured of mixtures between polymers (neutral Dextran T500 positively charged DEAE-dextran and negatively charged dextran sulphate) and proteins (BSA, ovalbumin, pepsin and lysozyme).The method is sensitive enough to detect interactions between the polymers and the p
Milk and whey are widely processed by membrane filtration, often using polysulphone membranes. Adsorption of β-lactoglobulin onto polysulphone was studied at protein concn. of 0.1 and 1.0%, as well as 12% to represent concn. encountered during ultrafiltration. Adsorption onto silica and methylated silica surfaces (representing strongly hydrophilic and strongly hydrophobic surfaces resp.) was also
