We report a rare instance of nine foreign bodies in a neonate that included a coin, safety pin, screw, cotton piece, polythene piece, and four glass pieces. Of these, six foreign bodies were removed by esophagoscopy and endoscopy, two glass pieces were passed in feces and one could not be removed. The child died 5 days after admission.

Ceramics and glass ceramics based on industrial waste have been widely recognized as competitive products for building applications; however, there is a great potential for such materials with novel functionalities. In this paper, we discuss the development of magnetic sintered glass ceramics based on two iron-rich slags, coming from non-ferrous metallurgy and recycled borosilicate glass. The s...

Growing concern over detrimental noise in densely populated areas has called for improvements in the sound insulation of our building spaces. While laminated safety glass has been optimized for safety and security and offers effective screening of UV-radiation as an additional benefit, its acoustic performance – although superior to monolithic glass – has not been given full consideration in th...

1 1. What’s New in Automotive Safety? Automobile safety technology advanced by great strides throughout the 20th century, from the first appearance of speedometers and electric headlamps, to the development of seat belts and safety glass, to the emergence of anti-lock brakes and airbags. As consumers demand safety, more and more automobile manufacturers are providing sophisticated technology, f...

Indoor evacuation systems are needed for rescue and safety management. One of the challenges is to provide users with personalized evacuation routes in real time. To this end, this project aims at exploring the possibilities of Google Glass technology for participatory multiagent indoor evacuation simulations. Participatory multiagent simulation combines scenario-guided agents and humans equipp...

Ultraviolet radiation (UVR) has known adverse effects on the skin and eyes. Practitioners are becoming more aware of the importance of outdoor photoprotection. However, little attention is directed to the exposure of the skin and eyes to UVR through the window glass or sunglasses. The amount of ultraviolet transmission through glass depends mainly on the type of the glass. All types of commerci...

To create a more cost effective glass while preserving its safety, the composition of soda-lime silicate glass was modified. The amount of Silicon dioxide in the composition was decreased in order to lower the melting point of the glass, thus making the new glass more cost-effective due to lower energy consumption. Calcium oxide and sodium oxide concentrations were increased to raise chemical d...

In this paper, a one-dimensional photonic crystal filter based on the [SiO2/ZrO2] bilayer have been designed for application in safety glasses for working in 350-nm wavelength. High power lasers with low wavelength e.g. 350-nm have very high power which can cause serious damage to the operator’s eyes. In this paper using the transfer matrix method and theoretical calculation in MATLAB software ...
