Molecular design and synthesis of hydroxide ion exchange membranes carrying alicyclic quaternary ammonium cations

Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and thermal stability. Studies o

Effects of delayed cord clamping on neurodevelopment and infection at four months of age : A randomised trial

Aim To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4 months of life. Methods Full-term infants (n = 382) were randomised to delayed (≥180 sec) or early cord clamping (≤10 sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4 months. Immunoglobulin G

PVL-positiva Staph aureus gav nekrotiserande pneumoni : Beskrivning av tre svära fall hos tidigare friska unga

We describe three cases of community-acquired pneumonia, in which the causative agent was methicillin sensitive S. Aureus positive for Panton-Valentine leukocidin (PVL). The patients were previously healthy children (2 weeks, 12 years and 15 years old). No epidemiologic connection existed, confirmed by spa-typing. Two cases were primary pneumonias with signs of necrosis, and the third case was a p

Cartilage-binding antibodies induce pain through immune complex-mediated activation of neurons

Rheumatoid arthritis-associated joint pain is frequently observed independent of disease activity, suggesting unidentified pain mechanisms. We demonstrate that antibodies binding to cartilage, specific for collagen type II (CII) or cartilage oligomeric matrix protein (COMP), elicit mechanical hypersensitivity in mice, uncoupled from visual, histological and molecular indications of inflammation. C

Pre-treatment 18F-choline PET/CT is prognostic for biochemical recurrence, development of bone metastasis, and cancer specific mortality following radical local therapy of high-risk prostate cancer

Background: The aim of this study was to determine whether lymph node metastasis on pre-treatment 18F-choline PET/CT is an independent prognostic factor for biochemical recurrence (BCR), skeletal metastasis, and cancer specific mortality (CSM), after radical local treatment (radical prostatectomy and/or radiotherapy) in men with high-risk prostate cancer. Medical records were reviewed for men with

Introduction of new systems for evaluation of ballast bearing capacity

The stiffness assessment of the trackbed should include an assessment of ballast, subballast and formation (e.g sub-ballast depth, groundwater profile). Furthermore, a lack of a systematic monitoring brings to the impossibility to produce an effective long term track management system, by allocating budget where emergencies come. Consequently, there is an increasing importance in obtaining a consi

Laser triangulation measurement system : Application on railway track

Railway tracks are complex systems, made up numerous critical components such as rails, sleepers/ties, fasteners, ballast, joints, crossings, switches, that require regular monitoring in order to ensure track safety and optimize track efficiency. Many large railways make use of expensive Track Geometry Cars in order to measure railway asset condition through the measurement of rail geometry (gauge

A new perspective in the road asset management with the use of advanced monitoring system & BIM

The present paper reports different applications which have a common data source: Automatic Road Analyzer (ARAN) of the Transport Infrastructure Laboratory of the University of Catania. Data surveyed with ARAN were used to develop performance indicators of the road asset. A BIM model makes possible to improve the flexibility in information access and to merge data with the aim to allow a complete

Investigating the influence of segmentation in estimating safety performance functions for roadway sections

Safety performance functions (SPFs) are crucial to science-based road safety management. Success in developing and applying SPFs, apart data quality and availability, depends fundamentally on two key factors: the validity of the statistical inferences for the available data and on how well the data can be organized into distinct homogeneous entities. The latter aspect plays a key role in the ident

Safety assessment of passing relief lanes using microsimulation-based conflicts analysis

The paper target is to analyze the influence of passing lane section and merging area lengths, which represent a critical part in the geometric design of passing lanes. The lack of observed data and the still limited implementation of short passing 2 + 1 lane in Poland do not allow to perform a reliable performance-based design of their length to balance context and economical restrains with opera

Monitoring of railway track with light high efficiency systems

Rail Track performance is highly dependent upon the magnitude and variation of differential track geometry. Consequently, there is an increasing interest in obtaining a consistent measure of trackbed stiffness and track geometry in the physical and time restrictions applicable on live track for assessing potential maintenance requirement and subsequent design of remedial measures. Furthermore, a l
