Hydrogen refueling stations are one of the key infrastructure components for hydrogen-fueled economy. Skid-mounted hydrogen (SHRSs) can be more easily commercialized due to their smaller footprints and lower costs compared stationary stations. The present work modeled explosions in a skid-mounted station predict overpressures hydrogen-air mixtures investigate protective effects different explos...

Construction and demolition waste (CDW) materials account for a considerable part of throughout the world. As these are not usually recycled, reusing them in construction projects is major significance. In this study, recycled concrete, bricks, glass were used as 100% aggregates chip seal, which corrective or preventive pavement maintenance method. A cationic rapid setting (CRS-2) bitumen emuls...

Abstract—The reheating furnace is used to reheat the steel slabs before the hot-rolling process. The supported system includes the stationary/moving beams, and the skid buttons which block some thermal radiation transmitted to the bottom of the slabs. Therefore, it is important to analyze the steel slab temperature distribution during the heating period. A three-dimensional mathematical transie...

Introduction: Asthma is a chronic inflammatory airway disease. Genetic and environmental factors have been important role in the induction of asthma. It's estimated that asthma affect 2.7 to 35.4% of child (in average 13.4%) in Iran. The aims of this study to assess the costs of asthma patients admitted in Boali hospital in Sari in the north of Iran. Patients and Methods: This descriptive study...

Forestry operations can significantly alter hydrological and erosional processes in a catchment. In the course of developing timberland, a network of persistent roads and skid trails causing soil compaction is usually established. Hereby, the infiltration rate of the soil is distinctly reduced, which leads to the generation of overland flow—this may also cause soil erosion. In this study, a sma...
