Central East Antarctic ice cores preserve stratigraphic records of mineral dust originating from remote sources in the Southern Hemisphere, and represent useful indicators of climatic variations on glacial-interglacial time scales. The peripheries of the East Antarctic Ice Sheet, where ice-free areas with the potential to emit dust exist, have been less explored from this point of view. Here, w...
BACKGROUND The prevailing view amongst neurosurgeons is that the larger the aneurysm, the higher the chance of rupture. This implies that very small aneurysms rarely rupture. To investigate this theory, we conducted a cross-sectional hospital-based study of aneurysmal subarachnoid hemorrhage, with an emphasis on aneurysm size at the time of rupture. METHODS We retrospectively reviewed hospi...
PURPOSE To study the tomographic and pathomorphologic features of dome-shaped maculas with swept-source optical coherence tomography (OCT). DESIGN Prospective, cross-sectional study. METHODS The macular area of 51 highly myopic eyes (35 patients) with dome-shaped maculas was studied with swept-source OCT at 1050 nm. Three-dimensional (3-D) data sets were obtained with raster scanning coveri...
Applying prestress is the key technique of the cable dome. However, it is difficult to ensure that designed prestress of cables have been exactly applied to the structure in the site due to the fact that various kinds of errors will be introduced during construction. Thus it is necessary to present an effective method to guide construction to avoid construction team regulate the real prestress ...
Dietary guidelines are important tool for selection a healthy diet. There is no special dietary guidelines for Arab people. Health Institutes are mainly using the Western dietary guidelines, such as American Food Pyramid. The objective of this paper therefore, was to summarize the steps taken by Arab Centers for Nutrition to establish "Food Dome", the dietary guidelines for the Arab countries. ...
Primary cultured monolayers of rat Type II pneumocytes were used to investigate the effects of NO2 on alveolar epithelial barrier properties. Such monlayers form fluid-filled domes which are thought to result from active solute transport from medium to substratum, with water following passively. Using dome formation as a transport marker, 5-day-old cultures were directly exposed to 30 ppm NO2 i...
The 1111-type iron-based superconductor LnFeAsO(1-x)Fx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into LaFeAsO by H, rather than F, revealed a double-dome-shaped Tc-x diagram, with a first dome (SC1, 0.05<x<0.20) and a second dome (SC2, 0.2<x<0.5). Here, we report the Tc for the whole hydrogen-doping range in LaFeAs...
