Magma is transported in brittle rock through dikes and sills. This movement may be accompanied by the release of seismic energy that can be tracked from the Earth’s surface. Locating dikes and deciphering their dynamics is therefore of prime importance in understanding and potentially forecasting volcanic eruptions. The Seismic Amplitude Ratio Analysis (SARA) method aims to track melt propagati...

UNLABELLED When cases of dental crowding are identified and diagnosed promptly, interceptive orthodontics is particularly successful. AIM To assess the differences in the eruption sequence of the mandibular canine and first premolar teeth in children with and without dental crowding. MATERIALS AND METHODS Children who attended the Shiraz Dental School's orthodontic clinic (Iran) from Septem...

Background The eruption pattern of temporary and permanent teeth are fairly constant with the growing age. So the age determination of an individual by examination of teeth is one of the accepted methods in legal system. A review of the literature shows there are differences in eruption pattern between different populations mainly due to variations in the constitutions and environment, so highl...

Canine forced eruption comprises one among a number of procedures that can be used in orthodontic treatment to ensure that cuspids are positioned in the dental arch in normal esthetic and functional conditions. Canine forced eruption should be characterized as an orthodontic movement. Unfortunately, in discussions of clinical orthodontic practice some professionals are reluctant to indicate ort...

An eruption is called 'fixed' if it recurs at the same site after re-exposure to the drug which precipitated the previous lesion. The eruption is commonly erythematous and sharply defined but may be bullous, herpetiform, or urticarial, and can be solitary or widely scattered. The commonest target areas are the trunk and the proximal portions of the limbs and the mouth, eyes, and urethra may som...

We apply a geospeedometer previously developed in this lab to investigate cooling rate profiles of rhyolitic samples initially held at 720^750‡C and quenched in water, liquid nitrogen, and air. For quench of mm-size samples in liquid nitrogen and in air, the cooling rate is uniform and is controlled by heat transfer in the quench medium instead of heat conduction in the sample. The heat transfe...

Eruption clouds in explosive volcanic eruptions are a kind of free boundary shear flow with very high Reynolds numbers (Re > 10), and their dynamics are governed by entrainment of ambient air into eruption clouds by turbulent mixing. We developed a numerical pseudo-gas model of an eruption cloud by employing three-dimensional coordinates, a high-order accuracy scheme, and a fine grid size in or...

Presently available research literature includes no less than a score of North American studies pertaining to the time and sequence of eruption of the primary or "'milk" teeth. For only about one-sixth of these studies is the medium of original report a dental periodical, the remaining five-sixths are in anthropologi-cal, biological, child development, medical (mainly pediatric) and psychologic...

Volcanic eruptions pose a threat to lives and property when volcano flanks and surroundings are densely populated. The local impact of an eruption depends firstly on its location, whether it occurs near a volcano summit, or down on the flanks. Then forecasting, with a defined accuracy, the location of a potential, imminent eruption would significantly improve the assessment and mitigation of vo...

Air transport supports economic growth and prosperity through the movement of passengers goods. As it grows more extensive complex, vulnerable its operations to unexpected natural disasters (e.g., typhoon volcanic eruption) will become. In Japan, many active volcanos are affecting airspace considered a threat national air transportation critical aviation equipment such as aircraft. The study fo...
