Need for designing certain important structures to resist blast loads is increasing in the recent past years, due to the enhanced terrorist operations. A bomb explosion can cause very serious damage on the building's external and internal structural frames. Collapse of one structural member in the vicinity of the source of explosion, may then create critical stress redistributions and lead to c...

Côte d'Ivoire has, in order to diversify its economic resources, decided exploit mineral reserves. Industrial gold mining began 1991 with the opening of Ity mine department Zouan-Hounien, west country. Several regions country have seen mines open. In Loh-Djiboua region, Divo, Hiré opened 2013. Mine operations consist mechanical extraction for oxidized ore but also blasting sulfired ore. Mining ...

BLAST is an automatic verification tool for checking temporal safety properties of C programs. Given a C program and a temporal safety property, BLAST either statically proves that the program satisfies the safety property, or provides an execution path that exhibits a violation of the property (or, since the problem is undecidable, does not terminate). BLAST constructs, explores, and refines a...

Blast has been the leading cause of injury, particularly traumatic brain injury and visual system injury, in combat operations in Iraq and Afghanistan. We determined the effect of shock tube-generated primary blast on retinal electrophysiology and on retinal and brain optic tract histopathology in a rat model. The amplitude of a- and b-waves on the electroretinogram (ERG) for both right and lef...

Correct selection of coefficients for blasthole parameters in Ghalat limestone mine in Shahr-e-kord of Iran has resulted is designing and performing 20 blasting operations. After each blast, fragmented rocks larger than one square meter, called oversize, are estimated and prepared for secondary blasting. Next blasthole pattern were designed based on previous blasting results. The results of the...

BACKGROUND/OBJECTIVE Soldiers of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF) sustain blast-related mild traumatic brain injury (concussion) with alarming regularity. This study discusses factors in addition to concussion, such as co-morbid psychological difficulty (e.g. post-traumatic stress) and symptom validity concerns that may complicate neuropsychological evaluation in the la...

Pulverized coal injection has assisted the steel industry to lower operating costs, extend coke oven life and lower greenhouse emissions. As the understanding of the impact of quality of the injected coal has increased, there has been a shift from high volatile thermal coals to low volatile semi-anthracites. A heat and mass model was used to investigate the impact of the injected coal propertie...

The modelling of consequences to built infrastructure when subject to blast loading is well developed; however, there is considerable uncertainty and variability with explosive loading and system response; which provides many challenges for collateral damage estimation. In this paper, structural facades are assessed – with a focus on glazing – as this is a structural and load-capacity system th...
