Particles of RuSeMo and RuSnMo have been produced by ball milling; they present catalytic activity towards the oxygen reduction reaction (ORR) in acid media. A Tafel slope close to 120 mV/dec was found for both materials. Their morphology was first characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and TEM images reveal particles in the sub-micromet

Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. To address this challenge, a novel, polymer-based neural probe, with protrusions tailored to the

In this study, a three-phase hollow fiber liquid-phase microextraction (HF-LPME) method combined with liquid chromatography-mass spectrometry was developed for direct determination of four non-steroidal anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) in sewage sludge. The drugs were extracted from non-spiked and spiked slurry samples with different amounts of sludge into a

Chronic lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are two lung diseases that are continuously increasing worldwide. Despite extensively research to find curative treatment, no so such therapy exists today. New hypothesis suggests that an aberrant chronic wound healing process takes place which involves both the classical inflammation and more chronic changes of

Upper limits on direct photon production were determined as a function of the transverse momentum for 0.7 < pT ≤ 3.2 GeV/c with the WA98 experiment in p + C and p + Pb collisions at . The results are compared to direct photon measurements in Pb + Pb collisions at by WA98. Implications for a possible thermal direct photon contribution are discussed.

Popular Abstract in Swedish Avhandlingens övergripande syfte är att kritiskt studera interorganisatoriska samverkansprocesser och sammanhängande konsekvenser, med ett särskilt fokus på rättens och maktens betydelse. Analysen av det empiriska materialet, som speglar samverkan i en kontext av barnahus på sex orter i Sverige (samverkan under ett tak kring utredningar av misstänkta brott mot barn), The overarching objective of the dissertation is to study inter-organisational collaboration processes and their associated consequences in a critical manner, with particular emphasis on the importance of law and power. The analysis of the empirical material, reflecting collaboration in the context of Barnahus on six locations in Sweden (collaboration under one roof regarding investigations of s

Commercial potato protein concentrate (PPC) was investigated as a source of thermoformed bio-based plastic film. Pressing temperatures of 100 to 190 degrees C with 15 to 25% glycerol were used to form PPC films. The shape of the tensile stress-strain curve in thermoformed PPC was controlled by glycerol level and was independent of processing temperature. Tensile testing revealed that elongation at

OBJECTIVE: To estimate the incremental cost-effectiveness of infliximab versus conventional combination treatment over 21 months in patients with methotrexate-refractory early rheumatoid arthritis. METHODS: In this multicentre, two-arm, parallel, randomised, active-controlled, open-label trial, rheumatoid arthritis patients with

An exploratory study of a train evacuation inside a tunnel was performed in order to study the effects of different train exit configurations on the flow rate of people through the exit. A total of 84 participants in the ages 18–40 years took part in the experiment, which was carried out on two separate days and involved 18 evacuation scenarios. The statistical analysis of the experiment demonstra

Context: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. Objective: To critically review the recent data on the management of NMIBC to arrive at a general consensus. Evidence acquisition: A detailed Med

The structuring of quantitative genetic variation can have a significant impact on the adaptive potential and long-term viability of species in changing landscapes. The present study of the grass Briza media investigated the relationships between patterns of heritable variation in phenotypic characters and descriptors of landscape structure, land-use history and local habitat conditions in a lands

Rhaphidicyrtis trichosporella (Nyl.) Vain. is reported here as new to Sweden from five sites in the southernmost part of the country, two in the province of Skåne and three in Småland. All sites are deciduous woodlands of different composition, but most likely with a long ecological continuity. Two records are from scaling bark of Alnus glutinosa in Alnus swamps, two from hard and smooth bark of F

The Kruppel-like protein ZNF224 is a co-factor of the Wilms' tumor 1 protein, WT1. We have previously shown that ZNF224 exerts a specific proapoptotic role in chronic myelogenous leukemia (CML) K562 cells and contributes to cytosine arabinoside-induced apoptosis, by modulating WT1-dependent transcription of apoptotic genes. Here we demonstrate that ZNF224 gene expression is down-regulated both in

A measurement of the total pp cross section at the LHC at root s = 7 TeV is presented. In a special run with high-beta* beam optics, an integrated luminosity of 80 mu b(-1) was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the diffe

Background: Bioethanol produced from the lignocellulosic fractions of sugar cane (bagasse and leaves), i.e. second generation (2G) bioethanol, has a promising market potential as an automotive fuel; however, the process is still under investigation on pilot/demonstration scale. From a process perspective, improvements in plant design can lower the production cost, providing better profitability an

Popular Abstract in English Colorectal cancer (CRC) is a cancer caused by uncontrolled cell growth in colon or rectum. CRC is the third most common cancer and the fourth leading cause of cancer related death in the world. It is a multifactorial disease, both genetic predisposition and environmental play a role in the development of CRC. CRC is closely linked to chronic inflammation. Patients with Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of death from cancer worldwide. People suffering from inflammatory bowel disease, such as Crohns’ disease and ulcerative colitis, are at an increased risk of developing CRC. The development of CRC is highly influenced by the tumour microenvironment. Tumour cells are able to recruit macrophages and change their beh
