Osteoporosis is a metabolic disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk. Bone fragility depends on bone density, turnover and microarchitectural features, such as relative trabecular volume, spacing, number and connectivity. Previous fragility fractures increase the frac...

Stings from scorpions (Buthus tamulus) produce acute myocarditis and can result in death in children and adults. Acute myocarditis was induced in anaesthetised dogs by intravenous injection of 4 mg/kg venom (Buthus tamulus). Myocarditis was confirmed by ECG. Blood was collected before and 30 minutes after venom treatment and processed for osmotic fragility. An increase in osmotic fragility of r...

The enthalpy relaxation is performed in the glassy Ge22Se78 to understand the dynamic behaviors. The structure of the glass is examined by X-ray diffraction and Raman spectra. The dynamic parameters such as the fragility, stretching exponent and non-linear factor are determined. A low fragility of m = 27 is exhibited for the chalcogenide, however, the stretching exponent is found not to have a ...

Osmotic fragility of erythrocytes was studied in ten Duchenne dystrophic patients and eight healthy controls. Lysis started in Duchenne crythrocytes at a concentration of 6.5 g/l NaC1 and in the control erythrocytes at a concentration of 5.5 gIl NaCI. At all concentrations of sodium chloride (from 6.5 g/l to 4.5 g/l) significantly greater lysis was observed in the erythrocytes of dystrophic pat...

Elastic moduli of the glass and fragility of the corresponding supercooled liquid were found to be correlated in recently published results. In the present work, compositions within the Ca-Mg-Cu system are used to study the relationships between liquid fragility, glass-forming ability and elastic properties. The correlation between liquid fragility and elastic properties already observed for gl...

Semi-fragile image authentication methods are robust to JPEG images, but are fragile to other malicious manipulations. This paper presents a novel digital signature scheme that adopts statistic Ogive analysis in quantized discrete cosine transform (DCT) coefficients to construct a feature code for image authentication. The lower bound sensitivity of fragility can be determined by a predetermine...

A magnetostriction oscillator has been used for determining the relative fragility of human red cells to 9000 cycle vibrations under some different environmental conditions. The destruction of the cells is a logarithmic function of time according to the equation See PDF for Equation. Hypertonic saline solution, saponin, preheating, alcohol, and ether in subhemolytic concentrations decrease the ...

[acyment,nicok,raltman,fasteasuain]@dc.uba.ar ABSTRACT AOP systems evolvability is severely affected by the tight coupling between aspects and base code. This paper identifies the advice fragility problem, originated in the advice’s need to access the application context while being oblivious to base code details. Proposed solutions to the pointcut fragility problem have generally put forward v...

The existence of systematic variations of isobaric fragility in different supercooled Lennard-Jones binary mixtures is revealed by molecular dynamics simulations. The connection between fragility and local structures in the bulk is analyzed by means of a Voronoi construction. It is found that clusters of particles belonging to locally preferred structures form slow, long-lived domains, whose sp...

A parameter that is often used to characterize the dynamics of supercooled liquids is the dynamic fragility, however it is still debated how the fragility is related to other physical properties. Recent experimental data on colloidal systems have found that fragility decreases with increasing softness of the intermolecular potential. This result is in apparent disagreement with recent molecular...
