Clinical Impact of Antibiotic Resistance
1998The development of antimicrobial agents for clinical use has brought unquestionable benefits to individuals and to society. Infections that formerly were frequently fatal have become routinely curable. Furthermore, the availability of effective antibiotic therapy has facilitated the employment by physicians of potent immunosuppressive therapy in the ...

Phenomenology of impact resistance and impact testing
Journal of Applied Polymer Science, 1965The impact resistance of plastics can be described in terms of three contributions; these are the elastic, plastic, and crack propagation phases. By using a recording pendulum impact device it is possible to analyze any material as to the relative importance of the above phenomena.

Impact of volume resistance on the surface resistance of paper
2018 19th International Scientific Conference on Electric Power Engineering (EPE), 2018In this publication, the paper deals with surface resistance, surface resistivity and volumetric resistance of electro- insulating materials. In the next part of the publication, an experiment is described which examines the surface resistance of paper and how the surface resistance is influenced by the number of paper stacked on top of each other.

Brittleness and Impact Resistance
Journal of the American Ceramic Society, 1969Impact resistance and brittleness have often been confused as identical properties for ceramic materials. This study determines the conditions under which the static characteristic of brittleness diverges from the dynamic characteristic of impact resistivity.

A drumhead for percussion instruments having improved resistance against denting and damaging by drumstick impact includes a synthetic plastic film base sheet and a protective overlay adhered to the upper, impact surface of the base sheet. The protective overlay consists of two thin sheets of woven synthetic plastic cloth which are bonded together with

During its service life, a structure may be subjected to various environmental and loading conditions. However, in general, the properties determined under one set of conditions may not be used to determine the behaviour of the material under a different set of conditions. For example, it is well known that concrete is a strain rate sensitive material;

Impact resistance: an overview.
Journal of the American Optometric Association, 1982The basic concepts of impact resistance are reviewed. Also discussed are the research on materials, treatment and testing procedures, mechanisms of fracture and the factors affecting impact resistance. Research has shown that the strength of a lens treated or untreated is well below the theoretical strength of glass.
