Rice blast, an erratic niche disease incited by Magnaporthe grisea Cav., frequently limits rough rice yields and grower cultivar options in Arkansas rice production areas. Scientists poorly understand why some blast-susceptible varieties such as ‘Newbonnet’, ‘LaGrue’, ‘Mars’, and ‘Cypress’ become increasingly more blast resistant if grown in continuously flooded soil. A greenhouse depth-of-floo...

The comparison of nucleotide or protein sequences from the same or different organisms is a very powerful tool in molecular biology. By finding similarities between sequences, scientists can infer the function of newly sequenced genes, predict new members of gene families, and explore evolutionary relationships. Now that whole genomes are being sequenced, sequence similarity searching can be us...

The paper defines and describes blast waves, their interaction with a structure and its subsequent response. Explosions generate blast waves, which need not be due to explosives. A blast wave consists of two parts: a shock wave and a blast wind. The paper explains how shock waves are formed and their basic properties.The physics of blast waves is non-linear and therefore non-intuitive. To under...

purpose: in recent years high explosive bomb attacks have been increasingly directed against   civil structures by various terrorist organizations. this paper describes a numerical method for   assessing the interaction of high explosive air blast within the complex geometrical type of a   congested urban environment.   materials and methods: the first step in predicting blast effects on a targ...

Current blast design provisions for wood members are limited and may unintentionally lead to designs that too conservative or not sufficiently safe. Novel methodologies the of light-frame stud walls, glulam members, as well cross-laminated timber (CLT) panels subjected loads proposed verified with published experimental full-scale test results. Additionally, static dynamic tests were conducted ...

OBJECTIVE Explosive blast mild traumatic brain injury (mTBI) is associated with a variety of symptoms including memory impairment and posttraumatic stress disorder (PTSD). Explosive shock waves can cause hippocampal injury in a large animal model. We recently reported a method for detecting brain injury in soldiers with explosive blast mTBI using magnetic resonance spectroscopic imaging (MRSI)....

Blast is the most common biotic stress leading to the reduction of rice yield in many rice-growing areas of the world, including Malaysia. Improvement of blast resistance of rice varieties cultivated in blast endemic areas is one of the most important objectives of rice breeding programs. In this study, the marker-assisted backcrossing strategy was applied to improve the blast resistance of the...
