Orbit-Orbit Resonance Capture in the Solar System

Science, 1972
A realistic model involving mutual gravitation and tidal dissipation for the first time provides a detailed explanation for satellite orbit-orbit resonance capture. Although applying directly only to Saturn's satellites Titan and Hyperion, the model reveals general principles of resonance capture, evolution, and stability which seem applicable to other

Magnetic Resonance Imaging of the Orbit

Radiologic Clinics of North America, 1987
Technological advances in MRI have resulted in the ability to obtain thin sections with high resolution; thus, MRI has become a serious competitor to CT in the evaluation of the orbit. MRI permits normal and pathologic anatomy to be visualized with exquisite detail in several planes.

Magnetic Resonance Imaging in Orbital Diagnosis

Radiologic Clinics of North America, 1988
Today, computed tomography is the primary diagnostic imaging test in orbital disease. Magnetic resonance in some instances is complementary and in a few conditions superior to CT. The relationship between these two imaging modalities is evolving.

Resonant orbitals in fluorinated epitaxial graphene

Physical Chemistry Chemical Physics, 2014
Fluorinated epitaxial graphene has potential applications in organic electronics. We present the calculation results by means of first-principles density-functional-theory for various fluorination patterns. Our results indicate that semi-fluorinated graphene conformations follow the same energetic order as the corresponding hydrogenated graphene ...

Magnetic Resonance Imaging of the Orbit

Seminars in Ophthalmology, 2008
Magnetic resonance imaging (MRI) employs the nuclear resonance phenomenon to produce images of living tissues. Unlike computed tomography (CT), which relies solely on differences in the propensity of tissues to absorb X-rays to produce various contrasts, MRI offers a wide variety of pulse sequences, each of which exploits differences in the magnetic ...

Magnetic resonance imaging of orbital tumors

European Radiology, 2006
This contribution provides an overview of diseases of eye and orbit and their appearance on magnetic resonance imaging. In recent years the diagnosis of eye and orbit pathology has profited significantly from increasingly sophisticated technical developments in the field of tomographic methods.

Magnetic Resonance Imaging of the Orbit

Topics in Magnetic Resonance Imaging, 1994
Magnetic resonance (MR) imaging plays an important role in evaluation of ocular and orbital lesions. Ocular tumors can be distinguished and delineated from adjacent fluid collections. Demonstration of internal septa within a well-defined mass leads to the diagnosis of cavernous hemangioma, whereas vascularity and internal lobulations are the hallmark ...

Higher order resonant orbits

Celestial Mechanics & Dynamical Astronomy, 1990
I present higher-order resonances of the tube and boomerang orbits in the co-rotating meridional plane of an axisymmetric galactic potential. Additionally, mirror forms of these orbits are given.

Orbiting sphere viscometer operated in resonant orbiting mode

2013 IEEE SENSORS, 2013
We present the operation of a previously introduced orbiting sphere viscometer in resonant mode at small amplitudes to demonstrate the feasibility of miniaturization. In chemical processes control, often comparability of novel viscosity measurement and sensing principles with well-established principles is essential since the measured viscosity ...
