This study simultaneously varied experiences of recent victory or defeat, 2-hour familiarity with the meeting place, and hen weight in order to understand their combined effects on the establishment of dyadic dominance relationships between hens not previously acquainted with each other. Three kinds of encounters were arranged: (i) a previous winner unfamiliar with the meeting place met a previ...

a telephone trumpet t. When the primary circuit is closed, the enclosed iron bar d becomes magnetised, and in its turn it magnetises the smaller bar b. Secondary currents are thus induced in the fine coil around b. It will be observed that the prolonged axis of d cuts b at its middle ; two secondary currents of equal strength and running in opposite directions are thus induced in the fine coil ...

Martin Kirschner cirujano alemán que empleó por primera vez alambres para la fijación de las fracturas, éstos en la actualidad son de uso frecuente en el tratamiento ortopédico, también desarrolló un abordaje para rodilla, cirugías en las extremidades, así como un método para realizar un esófago artificial, él fue primero en realizar una embolectomía de la arteria pulmonar llamada operación de ...

Polygonal subdivisions, i.e. the representation of categorical data in the vector model, are a common data type in GIS applications, in thematic maps, in topographic maps and in digital landscape models. Their cartographic generalization is termed polygon generalization. Cartographic generalization or generalization is one of the basic principles of cartography, namely the legible and comprehen...

OBJECTIVE : This paper reports the incidence, origin, course and anatomical relationships of intramuscular Martin-Gruber anastomosis. METHODS : Anatomical dissection of 100 limbs from 50 adults cadavers was performed. The intramuscular Martin-Gruber anastomosis was found in five forearms, three in the right and two in the left side, one was bilateral. All communication were located between th...

The number of households and businesses using HFC cable networks for Internet access is rapidly approaching 40 million in the United States. The cable industry has standardized on a single MAC and physical layer standard, the Data Over Cable System Interface Specification (DOCSIS). The emerging IEEE 802.16 broadband wireless access MAC protocol is based on DOCSIS. We have implemented a simulati...

Heights are functions that measure the arithmetic complexity of an algebraically defined object. They have become a major tool in many branches of number theory such as Diophantine analysis, transcendental number theory, Diophantine approximation, arithmetic of dynamical systems, etc. Moreover, they have also some very subtle functorial and functional properties, making it worthwile to study th...
