Introduction: Diagnosis of orbital foreign body (FB) penetration is usually obvious when part of the FB is still attached at the entry wound (1). However, the depth and course of the FB in this case was not visible.   Case Report: A 5-year old female presented with a pencil penetrating the left orbit. A computed tomography (CT) scan showed that the pencil penetrated the left orbit (extraseptal)...

Time evolution of wave packets built from the eigenstates of the Dirac equation for a hydrogenic system is considered. We investigate the space and spin motion of wave packets which, in the non-relativistic limit, are stationary states with a probability density distributed uniformly along the classical, elliptical orbit (elliptic WP). We show that the precession of such a WP, due to relativist...

BACKGROUND Porcine proliferative enteropathy in pigs is caused by the obligate, intracellular bacterium Lawsonia intracellularis. In vitro studies have shown close bacterium-cell interaction followed by cellular uptake of the bacterium within 3 h post inoculation (PI). However, knowledge of the initial in vivo interaction between porcine intestinal epithelium and the bacterium is limited. The a...

The major eruption of volcano Hunga Tonga-Hunga Ha'apai in Tonga on 15 January 2022 generated atmospheric Lamb waves that propagated over the world. This seemed first volcanic wave event was clearly captured by state-of-the-art geostationary meteorological satellites. paper provides visualization using thermal infrared images from satellite Himawari-8. second time derivatives 10-min interval il...

Abstract Tasmannia lanceolata (native pepper) has been reported as susceptible to Phytophthora cinnamomi and the objective of this study was identify variability in native pepper resistance P. . Plant material collected from populations across Tasmania (four regions) selected commercially grown cultivars, 47 clones were successfully propagated. Two disease screening experiments conducted “soil-...

Long-term configuration stability is essential for a space-based gravitational-wave observatory, which can be affected by orbit insertion errors. This paper investigated the of geocentric observatory from view uncertainty propagation. The effects errors on are propagated using Unscented Transformation (UT). best UT tuning factor selected based accuracy analysis different factors. position and v...

OBJECTIVES Chewing sugar-free gum has been shown to promote enamel remineralization. Manufacturers are now adding calcium to the gum in an approach to further promote enamel remineralization. The aim of this study was to compare the remineralization efficacy of four sugar-free chewing gums, two containing added calcium, utilizing a double-blind, randomized, crossover in situ model. METHODS Th...

Introduction:Many different kinds of chewing gum can increase the flow of saliva, and they have been proven to have anti-bacterial effects as well. The aim of this study was to compare the effect of natural turpentine and synthetic sugar-free gums on dental plaque pH after a sucrose challenge. Methods: This randomized clinical trial was conducted on 15 subjects, who refrained from oral hygiene ...
