Railway concrete sleepers have been developed and utilized in railway industry for over 50 years. Cyclic loading because of vibration on sleepers due to the train loading and the velocity of train itself and also a small percentage of bad wheels, can eventually lead to a crack network and failure of component. The objective of this study is to investigate the load carrying capacity of the selec...

This study presents experimental results performed on samples of Eutectic solder material (63 wt. % Sn 37 wt. % Pb). The tests were performed at high strain rates using Split Hopkinson’s Pressure Bar (SHPB). The strain rates were in the range of 400s -1 to 1300s -1 . Heating unit was added to conventional SHPB to vary initial sample temperature conditions. Tests were conducted at room temperatu...

OBJECTIVE Following partial meniscectomy, the remaining meniscus is exposed to an altered loading environment. In vitro 20% dynamic compressive strains on meniscal tissue explants has been shown to lead to an increase in release of glycosaminoglycans from the tissue and increased expression of interleukin-1alpha (IL-1alpha). The goal of this study was to determine if compressive loading which i...

We present a TEX macro package for generating the arabic writing from a standardized ASCII input notation. It can handle partial or full vocalization, and generates automatically most of the common ligatures. There is limited support for Farsi, Urdu, and Pashto. ArabTEX is compatible with Plain TEX and also most LATEX environments; arabic and other material can be mixed freely. For special purp...

This paper addresses the static properties and impact resistance of a ‘‘green’’ Ultra-High Performance Hybrid Fibre Reinforced Concrete (UHPHFRC). The design of concrete mixtures aims to achieve a densely compacted cementitious matrix, employing the modified Andreasen & Andersen particle packing model. The flowability, static mechanical properties and impact resistance capacity of UHPHFRC are m...
