Using a large sample of accounting data for non …nancial companies in France on the period 1990-2004, the paper studies the interactions between macroeconomic shocks and companies’…nancial fragility. We consider links in both directions, namely whether …rms’bankruptcies are a¤ected by macroeconomic variables, and whether bankruptcies determine the business cycle. We estimate forecasting equatio...

The fatigue performance from pre-corroded pits was studied in laser-shock-peened AA7075-T651 with and without a protective ablation-layer. Surface microstructural characterisation showed laser-shock-peening generated residual stresses up to −400MPa, limited hardness moderate surface roughness increase. specimens were exposed 3.5 wt-% sodium chloride solution for different levels of galvanostati...

A new theoretical Evans function condition is used as the basis of a numerical test of viscous shock wave stability. Accuracy of the method is demonstrated through comparison against exact solutions, a convergence study, and evaluation of approximate error equations. Robustness is demonstrated by applying the method to waves for which no current analytic results apply (highly nonlinear waves fr...

Various studies have been conducted to determine the dynamics that single packages undergo during distribution between destinations as a function of package size and weight and carrier. Previous studies have normally focused on regional and domestic measurements of these environments in Europe and North America. However, no information is available to determine the international handling and sh...

Adhesive bonding of metal sheets presents many practical advantages when compared to other joining methods, but its application for critical components is limited by the absence of reliable nondestructive methods that can assure the bond strength of the joint. In this paper, a method based on shock waves produced by pulsed lasers is applied to the evaluation of adhesive bond strength of two alu...

This paper reports modeling improvements for micro-scale laser shock processing (LSP), fatigue testing of shock processed copper samples, and microstructure characterization of shock processed materials (Cu and Ni). Plasma expansion is modeled as laser supported combustion wave, in which radial and axial expansions are considered. Stress/strain analysis is extended to three-dimensional and take...

INTRODUCTION Adrenal failure (AF) is associated with increased mortality in septic patients. Nonetheless, there is no agreement regarding the best diagnostic criteria for AF. We compared the diagnosis of AF considering different baseline total cortisol cutoff values and Deltamax values after low (1 microg) and high (249 microg) doses of corticotropin, we analyzed the impact of serum albumin on ...

Several mitigation and suppression policies, such as social distancing, city lockdowns, remote working, testing, providing personal protective equipment and health care resource availability have been implemented by the governments in response to Covid-19 pandemic. Until now (October 23, 2020), over 1.14 million deaths in the world including 31,650 just in Iran have been officially attributed t...

BACKGROUND Fluid resuscitation is considered a cornerstone of shock treatment, but recent data have underlined the potential hazards of fluid overload. The passive leg raise (PLR) test has been introduced as one of many strategies to predict 'fluid responsiveness.' The use of PLR testing is applicable to a wide range of clinical situations and has the potential to reduce fluid administration, s...
