A total of 1992 ISA Brown hens were housed from 18 to 70 weeks of age, in four different types of cages: 2 models of standard cages (S5 and S6) and 2 models of furnished cages (F7 and F15). These cages housed 5, 6, 7 and 15 hens respectively with areas per hen of 660, 635, 826 and 1134 cm2. Furnished cages were fitted with a nest, a dust-bath and perches. The mortality rate was higher in the st...

Based on the combination of a three-phase diode bridge and a dc/dc boost converter, a new three-phase threeswitch three-level pulsewidth modulated (PWM) rectifier system is developed. It can be characterized by sinusoidal mains current consumption, controlled output voltage, and low-blocking voltage stress on the power transistors. The application could be, e.g., for feeding the dc link of a te...

Critics of commodification object to sales but not gifts of some goods, such as human blood or human organs, on grounds that such trade wrongly coerces, morally corrupts, and crowds out altruism. This essay takes issues with each of these claims. It disputes Micheal Sandel’s claim that voluntary exchange coerces, arguing that he confuses what is unfair with what is unfree. It argues, where trad...

It is known that the total power electrical loads consume from mains sum of their two components – active and reactive. Most electric drives modern industrial enterprises up to 40% reactive energy in relation energy. This results an increased full consumption thereby increasing load on supply mains. Modern are built as follows: rectifier-direct current link-inverter asynchronous motor. The at "...

A Personal Network (PN) is a network of devices belonging to a person. It may consist of a number of ad hoc sub-networks which are linked together through the Internet or any other means. We study battery-aware routing in PNs, and propose a new battery-aware routing algorithm for multi-hop communication in sub-networks of PNs. The proposed algorithm considers the remaining battery energy of nod...

Décrit pour la première fois par Velpeau en 1937, le winging scapula reste une affection rare, encore peu connue aussi bien du grand public que des professionnels de santé. Il s'agit en fait de la paralysie isolée du nerf thoracique long, responsable de l'innervation unique du muscle serratus antérieur, laquelle paralysie génère un décollement du bord spinal et de la pointe de l'omoplate, parti...
