Comparison of Two Methods of Fatigue Testing Bone Cement.

Two different methods have been used to fatigue test four bone cements. Each method has been used previously, but the results have not been compared. The ISO 527 based method tests a minimum of 10 samples over a single stress range in tension only and uses Weibull analysis to calculate the median number of cycles to failure and the Weibull modulus. The ASTM F2118 test regime uses fewer specimens a

IgG4 subclass glutamic acid decarboxylase antibodies (GADA) are associated with a reduced risk of developing type 1 diabetes as well as increased C-peptide levels in GADA positive gestational diabetes.

Some women with gestational diabetes (GDM) present with autoantibodies associated with type 1 diabetes. These are usually directed against glutamic acid decarboxylase (GADA) and suggested to predict development of type 1 diabetes. The primary aim of this study was to investigate if GADA IgG subclasses at onset of GDM could assist in predicting postpartum development. Of 1225 women diagnosed with f

Pricing strategies and pricing capabilities

This article explores the intersection of pricing strategies and pricing capabilities by summarizing four distinct streams of research. By doing so, it provides insights into the challenges involved in implementing value-based pricing strategies as well as the generic challenges of building pricing capabilities. It also outlines the strategic importance of pricing capabilities.

Crystal structure of N-glycosylated human glypican-1 core protein: Structure of two loops evolutionarily conserved in vertebrate glypican-1.

Glypicans are a family of cell-surface proteoglycans that regulate Wnt, hedgehog, bone morphogenetic protein and fibroblast growth factor signaling. Loss-of-function mutations in glypican core proteins and in glycosaminoglycan synthezing enzymes have revealed that glypican core proteins and their glycosaminoglycan chains are important in shaping animal development. Glypican core proteins consist o

On mechanisms and models of multi-component gas diffusion in porous structures of fuel cell electrodes

Small scale particles/pores from micrometers and down to nanometers often occur in multi-functional porous electrodes in fuel cells, to enhance the catalytic reaction activities and accordingly the cell performance. Multi-component and -phase mass transport phenomena of reactants and products are strongly coupled with other transport processes as well as various reactions. All these processes form

Small bowel capsule endoscopy in the management of established Crohn's disease: clinical impact, safety, and correlation with inflammatory biomarkers.

Multiple studies have established the superior diagnostic accuracy of video capsule endoscopy (VCE) for the diagnosis of small bowel (SB) Crohn's disease (CD). However, data on the clinical impact of VCE in patients with established CD are scarce. The aim of this study was to examine the impact and safety of VCE on the clinical management of patients with established CD.

International Development of the Patient-Reported Outcome Indices for Multiple Sclerosis (PRIMUS)

Background: The Patient-Reported Indices for Multiple Sclerosis (PRIMUS) comprises a suite of three scales for assessing symptoms, activity limitations, and quality of life in multiple sclerosis (MS). It was developed in the UK and has been shown to have excellent psychometric properties. This study describes the adaptation of eight language versions for Canadian English, Canadian French, French,

Triangulating a Plane

In this theoretical paper we consider the problem of accurately triangulating a scene plane. Rather than first triangulating a set of points and then fitting a plane to these points, we try to minimize the back-projection errors as functions of the plane parameters directly. As this is both geometrically and statistically meaningful our method performs better than the standard two step procedure.

Three Theoretical Perspectives on Information Literacy

The concept of information literacy refers to purposeful information practices in a society characterized by almost limitless access to information and where information practices in digital environments shape and constitute important elements in most people’s lives in our part of the world. The meaning of the term information literacy varies according to the theoretical lens from which it is appr

Expression of insulin signalling components in the sensory epithelium of the human saccule.

Several studies have demonstrated a link between diabetes and the dysfunction of the inner ear. Few studies, however, have reported the signalling mechanisms involved in metabolic control in human inner ear cells. Knowledge of the expression and role of the insulin receptor and downstream signalling components in the inner ear is sparce. Our immunohistochemistry approach has shown that the insulin

Flicker is part of a multi-cue response criterion in fiddler crab predator avoidance.

Predator avoidance behaviour costs time, energy and opportunities, and prey animals need to balance these costs with the risk of predation. The necessary decisions to strike this balance are often based on information that is inherently imperfect and incomplete due to the limited sensory capabilities of prey animals. Our knowledge, however, about how prey animals solve the challenging task of rest

Frequency-modulated light scattering in colloidal suspensions

Frequency-modulated light field fluctuations due to moving particles in colloidal suspensions are examined using heterodyne interferometry. The power spectrum is the combined result of a time-of-flight-related frequency distribution due to light scattering and frequency shifts due to the Doppler effect. An approximation model is developed based on diffusion theory and verified experimentally. The

Kristina Söderbaum: Swedish citizen, Nazi superstar

This article deals with the reception of German film star Kristina Söderbaum in her native Sweden. Söderbaum reached the heights of superstardom, becoming one of Germany’s top box office stars of all time. Until 1945 she appeared exclusively in films directed by her husband, Veit Harlan. The Swedish press closely monitored Söderbaum’s career, though her most infamous film Jud Süss/Jew Süss (1940)

Pathogenic Ischemic Stroke Phenotypes in the NINDS-Stroke Genetics Network.

NINDS (National Institute of Neurological Disorders and Stroke)-SiGN (Stroke Genetics Network) is an international consortium of ischemic stroke studies that aims to generate high-quality phenotype data to identify the genetic basis of pathogenic stroke subtypes. This analysis characterizes the etiopathogenetic basis of ischemic stroke and reliability of stroke classification in the consortium.

Search for a Supersymmetric Partner to the Top Quark in Final States with Jets and Missing Transverse Momentum at root s=7 TeV with the ATLAS Detector

A search for direct pair production of supersymmetric top squarks ((t) over tilde (1)) is presented, assuming the (t) over tilde (1) decays into a top quark and the lightest supersymmetric particle, (chi) over tilde (0)(1), and that both top quarks decay to purely hadronic final states. A total of 16 (4) events are observed compared to a predicted standard model background of 13.5(-3.6)(+3.7) (4.4

An improved high-order scheme for DNS of low Mach number turbulent reacting flows based on stiff chemistry solver

We present an improved numerical scheme for numerical simulations of low Mach number turbulent reacting flows with detailed chemistry and transport. The method is based on a semi-implicit operator-splitting scheme with a stiff solver for integration of the chemical kinetic rates, developed by Knio et al. [O.M. Knio, H.N. Najm, P.S. Wyckoff, A semi-implicit numerical scheme for reacting flow II. St

Transient Colloidal Stability Controls the Particle Formation of SBA-15.

A hypothesis about (transient) colloidal stability as a controlling mechanism for particle formation in SBA-15 is presented. The hypothesis is based on results from both in situ and ex situ investigations, including cryogenic transmission electron microscopy (cryo-TEM), UV-vis spectroscopy, and dynamic light scattering (DLS). Cryo-TEM images show that particles grow via the formation of silica-Plu

Predictive markers of abdominal aortic stiffness measured by echo-tracking in subjects with varying insulin sensitivity.

Arterial stiffness is influenced by advancing age and vascular disease and is an independent risk factor for cardiovascular events and death. Using ultrasound measurements, arterial stiffness in a specific arterial segment can be assessed. The aim of this observational study was to explore the prospective and cross-sectional associations between arterial stiffness measured by ultrasound locally in
