Borrowing from multiple creditors exposes firms to liquidation risks due to coordination problems among creditors, but it also improves the firms’ repayment incentives, thereby increasing pledgeability. Based on this trade-off, I develop a dynamic debt rollover model to analyze the evolution of creditor dispersion. Consistent with empirical findings, firms optimally increase the number of credi...

despite the preventative and therapeutic effects of regular exercise, exhaustive exercise may be harmful to health. the present study aimed to determine the protective effect of endurance training and cinnamon bark extract (cbe) supplementation on oxidative responses induced by an exhaustive exercise schedule in rats. the rats were randomly divided into the following five groups of 6; control s...

April 14, 2013 was the 10th anniversary of the completion of the first draft of the Human Genome Project (http://www.genome.gov/). Results are still far from the revolution “in the diagnosis, prevention and treatment of human disease” forecasted by president Clinton. However, in the last decade psychiatric genetics has seen unprecedented advances in understanding the mechanisms underpinning man...

expansion equal channel angular extrusion (exp-ecae) is a severe plastic deformation (spd) operation for processing bulk materials. in the current study, aa7075 al was spd-processed by expansion equal channel angular extrusion (ex-ecae) at various temperatures and ram velocities. then, using split hopkinson pressure bar (shpb), the severely deformed products were compressed at room temperature ...

One hundred and forty-four years elapsed between the publication of Copernicus’s De Revolutionibus, which opened the great scientific revolution of the XVII century, and the publication of Newton’s Principia, the final synthesis that brought that revolution to a spectacularly successful end. During those hundred and forty-four years, the basic grammar for understanding the physical world change...

introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

Objective(s) The aim of this study was to investigate the effects of aerobics, pilates exercises and low calorie diet on leptin levels and some lipid profiles and anthropometric factors in sedentary women. Materials and Methods Forty six women (age 36.41±3.47) were recruited and divided into four groups: aerobic exercise group (EX), Pilates exercise group (Pilates), low calorie diet (LCD) an...

results a significant increase in blood abca1 (ex group p < 0.002, t = - 9.876) and apo a-i (ex group p < 0.05, t = 2.76) gene expression was shown following the 12 weeks of training. plasma high-density lipoprotein-cholesterol (hdl-c) concentration increased (p < 0.001, t = 4.90 respectively) while plasma low-density lipoprotein-cholesterol (ldl-c) concentration decreased (p < 0.001, t = 4.27)...
