Models of topographic support on Europa by lateral shell thickness variations have previously assumed a Newtonian ice viscosity. Here I show that using a more realistic stress-dependent viscosity gives relaxation times which can be significantly different. Topography of wavelength 100 km cannot be supported by lateral shell thickness variations for ∼ 50 Myr, unless the shell thickness is < 10 k...

AIM To evaluate corneal topographic changes and surgically induced astigmatism (SIA) after combined phacoemulsification and 25-gauge transconjunctival sutureless vitrectomy (25-G TSV). METHODS A retrospective study on 96 eyes of 87 patients who underwent combined phacoemulsification and 25-G TSV. The different topographic parameters and SIA were analyzed pre- and postoperatively. RESULTS Th...

Abstract We present new high-resolution topographic, illumination, and thermal models of Mercury’s 112 km diameter north polar crater, Prokofiev. The confirm previous results that water ice is stable at the surface within permanently shadowed regions (PSRs) Prokofiev for geologic timescales. largest radar-bright region in confirmed to extend up several kilometers past boundary its PSR, making i...

this study tried to explore disciplinary variations of web blurbs across soft and hard knowledge fields on the one hand, and to illustrate how academic publishers exploit interactional metadiscourse devices in move structure of their blurbs on the other.

The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987–1993) within images of satellite-derived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF that strongly affect spatial and temporal variability. Over the deep ocean basins...

Topographic decorrelation due to the local surface slope has been an obstacle to interferometric synthetic aperture radar (InSAR) applications. A modified spatial decorrelation function is derived as a function of the baseline and topography. This function explains the origin of the total topographic decorrelation phenomenon on the slopes directly facing radar illumination and layover, which ma...

Landslide is one of the natural disasters that occur in Malaysia. Topographic factors such as elevation, slope angle, slope aspect, general curvature, plan curvature, and profile curvature are considered as the main causes of landslides. In order to determine the dominant topographic factors in landslide mapping analysis, a study was conducted and presented in this paper. There are three main s...

Because yield maps provide only synthetic information on the whole crop cycle, it appears necessary to supplement them with more analytical tools enabling to explain the spatial variations in measured yield and to make diagnosis. Here we tested two candidate methods: simulation modelling and radiometric mapping of green leaf area index (GLAI) after anthesis, on a 15-ha wheat-cropped field with ...
