BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperat...
Volvulus is possible in any portion of the intestinal tract from the stomach to the sigmoid colon. Thus volvulus of the stomach, due to gastroptosis, an hour-glass contraction or certain kinds of injury, although extremely rare, is known. Volvulus of Meckel's diverticulum when it is persistent is recorded. Similarly volvulus of the small intestines, the ileo-csGcal junction or even of the csecu...
AIM To analyse serious eye injuries caused by bottles containing pressurised drinks. METHODS Retrospective review of the databases of US, Hungarian, and Mexican eye injury registries. RESULTS In the combined database (12 889 injuries), 90 cases (0.7%) were caused by bottle tops or glass splinters. The incidence varied widely: 0.3% (United States), 3.1% (Hungary), and 0.9% (Mexico), as did t...
Unregulated, pseudomedical procedures risk serious sequelae even when otherwise safe compounds are used. Silicone is commonly used legally in cosmetic procedures owing to its durability, resistance to heat and aging, and low immunogenicity. However, inappropriate or illegal silicone injection can pose severe local and systemic complications including serious pulmonary compromise. We describe th...
A 73-year-old man was admitted in respiratory failure that had subacutely progressed after five weeks of dapsone treatment for a skin rash. He also presented with fever, systemic erythroderma and liver dysfunction. Chest computed tomography showed diffuse reticular shadows with ground-glass opacity and bilateral mediastinal lymphadenopathy. Lymphocytes, but not eosinophils, were increased in th...
background: injury is a leading cause of morbidity and mortality in children. there is insufficient data on the epidemiology or incidence of injuries in the first two years of life, especially in iran. the main objective of this study was to describe the incidence and causes of injuries in a sample group of infants and toddlers in mashhad, iran. methods: this prospective, observational study, w...
INTRODUCTION Bombings, including the 1995 Oklahoma City bombing, remain an important public health threat. However, there has been little investigation into the impressions of injury risk or protective factors of bombing survivors. OBJECTIVE This study analyzes Oklahoma City bombing survivors' impressions of factors that influenced their risk of injury, and validates a hazard timeline outlini...
Terbium oxide doped tetraborate glasses were prepared from the reaction of Tb2O3 and Na2B4O7 .10 H2O on reagent grade. At first, the base borate glass of Na2B4O7 was prepared by melting dehydrated borax at 1000 ˚C for 30 min and then the obtained base glass was crushed and powdered. Appropriate amounts of Tb2O3 (5-20 mol %) and Na2B4O7 powdered glass were mixed and melted at 1200 ˚C for 15 min....
OBJECTIVES To evaluate characteristics and prognostic factors of open globe injuries (OGI) presented to King Fahad Specialist Hospital in the Jazan region, Saudi Arabia. Methods: This study is a retrospective review of medical records of OGI patients who underwent operative repair of their injuries in King Fahad Central Hospital, Jazan, Saudi Arabia between January 2011 and December 2013. Demo...
Amorphous steel slag was blended with different concentrations of waste glass (20, 40, 50, 60, 70 wt.%) and SiC to obtain a composite. According to Hot Stage Microscopy images, slag-glass composite contractions started at 1050 ºC. scanning electron microscope micrographs of slag-SiC (foaming agent) composite revealed tunnel-like porosities of 500 to 1000 microns. Gaseous products of carbide dec...
