In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...

Many long established US DOE facilities are in possession of poorly documented wastes in a variety of forms spanning a broad range of waste containers, waste matrices and isotopic mixtures. Existing assay technologies such as the SuperHENC can address many of the expected waste configurations. However, there are also expected waste items that fall outside the normal operating range of these exc...

Determining the compressive strength of concrete is important in all phases construction and diagnosing technical condition existing reinforced buildings facilities during their service. In this article, author presents experimental results from research conducted over 6 years. The following non-destructive methods were used tests—elastic rebound, ultrasonic, SonReb destructive methods, latter ...

An increasing number of marine structures are utilizing composite materials. Major structure and components can be built lighter and corrosion-resistant using composite construction. The recreational boating industry has long recognized this and now commercial ferries are increasingly realizing fuel savings through weight reduction. The US Navy’s DDG-1000 topside structure and LPD-17 advanced e...

BACKGROUND Non-Inflammatory Destructive Periodontal Disease (NIDPD), is a severe destructive periodontal disease, that is characterized by the attachment loss and alveolar bone loss, without signs of the gingival inflammation, and the periodontal pocket development. OBJECTIVE Despite the fact that various cases of NIDPD have been reported; their etiology and disease evolution is still indefin...
