Objective—To evaluate the eVectiveness, in terms of injury prevention, of toughened pint glassware in bars. Design—Randomised controlled trial. Setting—A random sample of 57 bars in South Wales, West Midlands, and West of England. Subjects—A total of 1229 bar workers. Intervention—Complete replacement of pint glasses with annealed (control) or toughened (intervention) glassware. Main outcome me...

The effects of lung injury, positive end-expiratory pressure (PEEP), and norepinephrine on heterogeneity of regional pulmonary blood flow (rPBF, radioactive microspheres) were investigated. We hypothesized that lung injury increases heterogeneity of rPBF and that PEEP ventilation reduces these effects. Heterogeneity of rPBF is scale dependent and was therefore assessed in detail. Local correlat...

Laminated safety glass is used in the automobile industry and in architectural applications. Laminated safety glass consists of a plastic interlayer, such as a layer of poly vinyl butyral (PVB) or Butacite, surrounded by two adjacent glass plates as shown in Figure 1. The glass can be float glass, plate glass, tempered glass, or sheet glass, and the plastic interlayer is made of a viscoelastic ...

Personnel injury from flying glass produced during an explosion accident can represent a significant hazard, often in excess of hazards due to airblast, primary fragments, building collapse, and secondary fragments. The permissible overpressure in Inhabited Building Distance (IBD) from a Potential Explosion Site (PES) is 1.2 psi. This pressure is sufficient to cause failure of most windows in c...

In a bicycle–vehicle or motorcycle–vehicle accident, the head of an adult rider with helmet is very likely to impact windshield laminated glass. Such complex phenomenon normally involves injury, failure, and damage. The main purpose this work present computational framework for modeling interaction between helmeted headform glazing. To achieve this, finite element model established, where crush...

Idiopathic interstitial pneumonias are currently classified into four categories: usual interstitial pneumonia, nonspecific interstitial pneumonia with fibrosis, acute interstitial pneumonia and desquamative interstitial pneumonia. The fibrotic process in interstitial pneumonias appears to result from a complex interaction between fibroblasts, other lung parenchymal cells and macrophages. The c...

The menisci protect the articular cartilage by reducing contact pressure in the knee. To restore their function after injury, a new silk fibroin replacement scaffold was developed. To elucidate its tribological properties, friction of the implant was tested against cartilage and glass, where the latter is typically used in tribological cartilage studies. The silk scaffold exhibited a friction c...

PURPOSE To describe a case of free migration of intraocular glass in aphakia after glaucoma surgery. METHODS We report the case of a 27-year-old man with a history of perforating injury to the right eye 10 years previously and glaucoma surgery 1 year previously presenting with 1 month of pain and frequent floaters in front of the right eye. On examination, the glass fragment was seen to lie f...

BACKGROUND AND OBJECTIVES Glass ampoules have been widely used in packaging injection drugs. Glass has important characteristics that allow it to be widely used in fabrication of recipients for drugs and other sterile substances. However, contamination of solutions with glass microparticles on breaking open glass ampoules, the presence of metals, percutaneous injury, and biological contaminatio...
