Steam traps play a significant role in condensate evacuation from steam as well heating ventilation and cooling systems (HVAC), i.e., industrial climate chambers. Preventive maintenance periodical audit of increase reliability reduce the number facility off hours. In some elements system, can damage parts, which means that monitoring their function is one basic preventive tasks. One way checkin...

Industrial ventilation and air conditioning systems aim to ensure the conditions of purity microclimate corresponding activity man nature technological process. The parameters state which are interest for technique are: temperature humidity, atmospheric pressure, speed. For study on variation inside industrial installations, in experiment laboratory, systems, was performed circulation through d...

The aim of this paper is twofold: first, to explore the effects of industrial cluster on innovation capacity, and second, to study the impact of external resources on firms’ innovation capacity especially under Chinese regional economic policy. This is a critical subject that lacks sufficient analysis. Through years of investment and effort, several IT industrial clusters have developed in Chin...

The heat released by local exhaust ventilation is one of the most common hazards emitted during various industrial processes in buildings. This work solves problems order to find numerical solution model that adequately describes development a free convective jet above flat source and near side hood located source. Various turbulence models options wall functions are considered for application ...

A previously healthy 24-year-old male-to-female transsexual presented with a 48-h history of dyspnea, fever, and signs of severe hypoxemia (SpO 2 , 72%). The patient reported having undergone an illegal procedure 10 days prior, when industrial liquid silicone had been injected into her buttocks for cosmetic purposes. The patient had previously received silicone breast implants. After admission,...

background: welding is one of the most exercised industrial processes which welders are exposed to chemical and physical hazardous agents. this study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. methods: a total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of wel...

abstract background: transtracheal jet ventilation is an alternative ventilatory approach in airway surgery. the purpose of this study was to compare respiratory efficacy of percutaneous transtracheal with endotracheal, low frequency jet ventilation during microlaryngeal surgery. methods: ninety asa class i-ii patients aged between 16 and 70 years undergoing elective microlaryngeal surgery were...
