BACKGROUND AND PURPOSE Aneurysm geometry has been shown to predict the need for adjunctive techniques in the endovascular treatment of intracranial aneurysms. We conducted a systematic retrospective study examining which thresholds of dome-to-neck ratio, maximum neck width, and aspect ratio of intracranial aneurysms best predict the need for adjunctive techniques in endovascular management. M...

OBJECTIVE Validation of a bedside test to measure the monocular and binocular subjective visual vertical (SVV). METHODS Monocular and binocular measurements of the SVV were made in 30 healthy subjects (mean age 46.1 +/- 16.4 years) and 30 patients with acute peripheral or central vestibular lesions (mean age 51.3 +/- 17.1 years). The established method uses a hemispheric dome (adjustment of a...

The best ground-based astronomical sites in terms of telescope sensitivity at infrared and sub-millimetre wavelengths are located on the Antarctic plateau – where high atmospheric transparency and low sky emission are observed due to the extremely cold and dry air; these benefits are well characterised at the South Pole station. The relative advantages offered by three potentially superior site...

Dome-shaped macula is described as an inward bulge of the macula within a posterior staphyloma in highly myopic eyes. Choroidal neovascularization is a known complication that can cause visual loss in dome-shaped macula. Herein, we describe a patient who presented with features of polypoidal choroidal neovascularization that developed on a background of high myopia with dome-shaped macula.

Introduction: Lunar concentric craters represent an anomalous type of impact structures on the Moon [1]. The concentric crater Archytas G in mare Frigoris has first been catalogued as a concentric crater in [2]. According to Fig. 1, it is located on top of a large lunar intrusive dome, termed Ar1 in [3]. The dome Ar1 is the only lunar dome known to date with a concentric crater on its surface. ...

It has been shown that the maxillary palps of Locusta migratoria (L.) play an important part in food selection when the insect has not been deprived of food for a long period (Blaney & Chapman, 1970; Blaney, Chapman & Wilson, 1973). The receptors primarily concerned are those on the flexible dome at the distal tip of the palp, and in the fifth instar larvae of Locusta there are about 370 of the...

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

A decade of site testing at the South Pole has shown that the Antarctic Plateau can offer enormous opportunities for astronomers. The combination of extreme cold and dryness, high altitude and very low wind speeds throughout the troposphere confers powerful advantages—especially for infrared and sub-millimetre astronomy. However, Dome C is higher, drier and colder than South Pole, and has signi...
