Background: Intraocular foreign bodies (IOFBs) such as air gun pellet is a rare finding in wild animals like Rhesus macaque (Macaca mulatta). The purpose of the present scientific report is to describe the surgical retrieval of IOFB secondary to ballistic wound in a wild Rhesus macaque. Case description: A juvenile female wild Rhesus macaque was brought with the history of swollen and inflamed ...

growing demand of invisible braces byesthetically conscious patients has led to remarkable inventions in materials for esthetic labial archwires. archwires with excellent optical clarity and mechanical properties comparable to conventional archwires have been manufactured by almost all the leading companies of orthodontic products in the past two decades, but their clinical use is still limited...

BACKGROUND Carcinogenicity of nickel compounds has been well documented. However, the carcinogenic effect of metallic nickel is still unclear. The present study investigates metallic nickel nano- and fine particle-induced apoptosis and the signal pathways involved in this process in JB6 cells. The data obtained from this study will be of benefit for elucidating the pathological and carcinogenic...

It is shown that certain metallic photonic crystals can enable negative refraction and subwavelength imaging without relying on a negative effective index. These metallic structures are very simple in design and appear straightforward for fabrication. Their unusual electromagnetic response should provide an interesting comparison with the metallic left-handed materials.

The backscattering contribution to the conductivity, irrelevant for metallic single-walled carbon nanotubes, is proved to become much significant for doped semiconducting systems, in agreement with experiments. In the case of multi-walled nanotubes, the intershell coupling is further shown to enhance the contribution of backscattering for ”metallic” double-walled, whereas it remains insignifica...

in this paper, the evidences and remnants of archaeometallurgical activities in elamite site of haft tappeh (14th century bc) have investigated and identification of archaeometallurgical materials have been done based on analytical investigations. sem-eds analysis and metallography were used to identify the chemical composition and microstructural features of archaeometallurgical materials in h...

Metallic glasses are amorphous materials that possess unique mechanical properties, such as high tensile strengths and good fracture toughnesses. Also, since they are amorphous, metallic glasses exhibit a glass transition, and at temperatures above this glass transition, they soften dramatically and are therefore amenable to net-shape thermoplastic forming processes. This combination of superio...
