Increasing the Blast Resistance of Concrete Masonry Walls Using Fabric Reinforced Cementitious Matrix (FRCM) Composites
… from different sources , including seismic or blast events. When subjected to blast, wall elements experience large pressures on one of their faces due to the high pressure produced in the air when an explosion takes place. This wave of compressed air travels in a very short time and hits the …

Nanoenhanced Polyurea As A Blast Resistant Coating For Concrete Masonry Walls
Blast impact is a major concern in the world today. The leading cause of death due to blast impacts is rapidly moving debris. To prevent this many researchers are looking for methods of improved blast resistance for concrete masonry walls. However, many available protective coatings are not flame …

Finite Element Analysis of the Application of Synthetic Fiber Ropes to Reduce Blast Response of Frames
Blast resistance has recently become increasingly relevant for structural engineers. Blast loads are created by explosive devices that, upon detonation, create pressure loads that are much higher than most that a structure would ever experience. While there are many types of blast loads that are …

Adhesive properties of thermoset fibre metal laminates
… to its damage tolerance and potential impact and blast resistance. GLARE is not commercially available and attempts at manufacturing FMLs similar to GLARE at the Blast Impact Survivability and Research Unit (BISRU) laboratories have been unsuccessful. The FMLs readily exhibited debonding between …

Rice Blast Disease in the U.S. and Africa: Determination of Pathogen Diversity and the Identification of Resistance Genes for Disease Management
<p>Rice blast caused by Magnaporthe oryzae (= Pyricularia oryzae) B. Couch, is a leading disease of rice. Magnaporthe oryzae exhibits a high degree of diversity. The diversity of isolates of M. oryzae from Africa and the U.S. were examined using vegetative compatibility and virulence phenotyping as …
