Orbita

Mechanics of the orbita.

The oculomotor periphery was formerly regarded as a simple mechanism executing complex behaviors explicitly specified by innervation. It is now recognized that several fundamental aspects of ocular motility are properties of the extraocular muscles (EOMs) and their associated connective tissue pulleys. The Active Pulley Hypothesis proposes that rectus and inferior oblique EOMs have connective t...

Ein routine-integrierbares Planungswerkzeug zur operativen Rekonstruktion der Orbita

Kurzfassung. Bei Frakturen des Orbitabodens kann ein Titangitter zur Rekonstruktion operativ eingesetzt werden. In dieser Arbeit wird ein Planungswerkzeug entwickelt, welches mit Hilfe eines aktiven Konturmodells die Orbita in CT Daten segmentiert, ihr Volumen berechnet und visualisiert. Neben den technischen Integrationsstufen der Funktionsund Präsentationsintegration, welche durch den Einsatz...

Natural Product Research in the Australian Marine Invertebrate Dicathais orbita

The predatory marine gastropod Dicathais orbita has been the subject of a significant amount of biological and chemical research over the past five decades. Natural products research on D. orbita includes the isolation and identification of brominated indoles and choline esters as precursors of Tyrian purple, as well as the synthesis of structural analogues, bioactivity testing, biodistribution...

Seasonal clill1.atic forcing of alpine glaciers revealed with orbita l synthe tic aperture radar

The evolut ion of four dynamic radar glacier zones at the surface of an alpine icefield in British Columbia is monitored using a time series of 35 First European Remote Sensing Satellite ( ERS-I ) synthetic aperture radar (SAR) i mages acquired from 1992 to 1994 . These zones result from changing wetness and textural properties, and ap­ pear to represent: (I) cold snow with no l iquid water pre...
