By taking the super-long railway tunnel as the object of research, based on setting problems of emergency stations adopted by super-long railway tunnels, from the viewpoint of people's safe evacuation, several aspects were studied, such as the mode of evacuation and rescue by adopting emergency station, the number and interval of the cross passage, and the people's safe evacuation time under di...

Many people heat their homes with wood-burning stoves. However, toxic fire effluent can escape from old or improperly operated stoves. The authors describe a case in which bronchiolitis obliterans developed in a man within hours after he burned synthetic construction materials in his wood-burning stove. Certain factors, such as careless or improper use of the stove, the size of the room, the la...

awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. in this study, effects of fire onphysical and chemical characteristics of soil were investigated. this research was carriedout in a randomized block design method in the...

covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. while numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. random generation techniques c...

This paper displays how to derive the factors of Ubiquitous Sensor Network (hereafter, USN) technology that comprise inspection, plan, construction and maintenance ahead of launching construction of intercity highways that are the key to civil constructions for urbanization. And it also shows the plan of USN technologies currently adopted in each process of construction areas, grouped into Tunn...

fire blight is an important worldwide disease of pome fruits that control of which through antibiotics is particularly critical. in this case and in absence of another chemical methods, the biocontrol methods can be considered as the best alternative for control of fire blight. in this study efficacy of 5 isolates of antagonistic bacteria belongs to pseudomonas fluorescens and pantoea agglomera...
