Background: Fire and explosion hazards are extremely important in processing units. This study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. Materials and Methods: The present qualitative case study was conducted using Dow’s index in 2015. The fire and explosion hazard index...

ABSTRACT I analyse some properties of the luminous transient event SN 2019zrk and conclude that jets were main powering sources pre-explosion outburst (pre-cursor) ejection a massive circumstellar matter (CSM), very energetic explosion itself, post-explosion bump in light curve. The energy source is mainly companion (main sequence, Wolf–Rayet, neutron star, or black hole) star accreted mass lau...

In research studies, a student starts with writing a research proposal, followed up by intensive literature and industrial survey in his/her own research area. The student must perform his/her own research with validation under supervisor’s guidance. The student’s own research work must be differentiated from others work in order to demonstrate the unique originality and significance of the stu...

With the increasing complexity of control rooms and the information explosion, effective multitasking is now desired. Monochronicity and polychronicity, which describe a person's ability to do one thing and many things at a time, respectively, have been studied for a long time. However, it is not clear these abilities are related to various individual characteristics. Forty-eight Chinese partic...

Looking back over the last three decades of Roman archaeology I find it difficult not to be impressed by the huge advances the discipline had made. The quantity of information collected has increased enormously. Romanists have enthusiastically embraced new archaeological technologies, and entire new subject areas landscape archaeology, palaeopathology, and underwater archaeology for instance ha...

In research or experimental works related to blast loads, the amount of explosion material and distance of explosion point are very important. So, in this paper has been attempted to present a parametric study of the reactive powder concrete subjected to blast load. The effect of the different amount of TNT adopted the literature, distance of explosion point from RPC slab and also the location ...

the history of five thousand years of human civilization (with only 292 years with no war) and the experiencesof the past two decades of our country shows that the enemies’ approach is based on strong air attack just inthe first month, and civilians bombarding begins if the spirit of national defense continues after two weeks.so the buildings in the cities are damaged in different ways by the a...

Computing has been an enormous accelerator to science and it has led to an information explosion in many different fields. Future advances in science depend on the ability to comprehend these vast amounts of data. In this paper, we discuss challenges and opportunities for social data analysis in the scientific domain.

The hypothesis is considered that: Once an AI system with roughly human-level general intelligence is created, an “intelligence explosion” involving the relatively rapid creation of increasingly more generally intelligent AI systems will very likely ensue, resulting in the rapid emergence of dramatically superhuman intelligences. Various arguments against this hypothesis are considered and foun...
