We present an analytic scheme to connect the fragility and viscoelasticity of metallic glasses to the effective ion-ion interaction in the metal. This is achieved by an approximation of the short-range repulsive part of the interaction, combined with nonaffine lattice dynamics to obtain analytical expressions for the shear modulus, viscosity, and fragility in terms of the ion-ion interaction. B...

Objective To identify the prevalence of osteoporosis and hypovitaminosis D among patients at the Siriraj Metabolic Bone Disease (MBD) Clinic, and to compare initial vitamin D levels in patients with and without a history of fragility fractures. Methods Medical records of patients who attended our MBD clinic between 2012 and 2015 were retrospectively reviewed. Patient baseline demographic, cli...

Background Calcium and Vitamin D supplementation in elderly patients may decrease the risk of hip fracture by up to one-third. Many patients suffering fragility fractures do not go on to receive this treatment despite clear recommendations from the National Institute for Health and Clinical Excellence (NICE). The aim of this study was to audit the proportion of patients admitted with a hip frac...

The aim of this commentary is to address a number of issues and omissions arising from the integrative review of Bulmer-Smith et al. (2009) on emotional intelligence (EI) and nursing. An important objective is to bring to the attention of readers the growing research on trait EI (or trait emotional self-efficacy), which did not feature in Bulmer-Smith et al.’s review. As a scientific alternativ...

The pharmacokinetics and analgesic effect of i.v. ketamine in doses of 125 microgram kg-1 and 250 microgram kg-1 were determined in five healthy volunteers. Analgesia was measured with the submaximal effort tourniquet test. Both doses of ketamine prolonged the period of pain-free ischaemic exercise while the plasma ketamine concentration was greater than 100 ng ml-1. Ketamine was distributed ra...

Research on state fragility has seldom examined questions of persistence and transition of states. We develop a sixfold typology of states to examine how key structural features of states evolve and contribute to successful exits from fragility in some cases and persistence in others. Particularly worrisome is the lack of positive transition among the weakest states. Our findings are derived fr...

This paper, introduces a new methodology for the design and analysis of digital watermarking systems which, from an information theoretic point of view, incorporates robustness and fragility. The proposed methodology is developed by focusing on the probability of error versus watermark-to-noise ratio curve, describing the technique performance, and a scenario for coded techniques which takes in...

Abnormalities in osmotic fragility have been observed in hereditary spherocytosis, hereditary elliptocytosis, pyruvate kinase deficiency, thalassaemia and iron-deficient red cells (1). Harris et al have reported a decrease in osmotic fragility of the red cells of sickle cell anaemia patients from Africa (2). The Indian patients are genetically and clinically different from the African patients ...

I T HAS been demonstrated by Fahraeus’4 that normal red blood cells have a tendency to bcccme spheroidal in shape after standing in vitro at body ternperature. G#{228}nsslen,5 Haden6 and Castle and Daland7 have shown that spheroidal red cells are more susceptible to osmotic hemolysis than are normal corpuscles. Haden found that normal red cells when suspended in graded hypotonic salt solutions ...
