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...

Aeromonas spp. are among the most ubiquitous microorganisms, as they have been isolated from different environmental niches including waters, soil, as well as wounds and digestive tracts of poikilothermic animals and humans. Although much attention has been paid to the pathogenicity of Aeromonads, the role of these bacteria in environmentally important processes, such as transformation of heavy...

Introduction: The identification of various iron and magnesium sulfates in data from the Mars Exploration Rovers (MER), OMEGA on Mars Express, and CRISM on MRO [e.g. 1-5] provides the impetus to explore analog environments that produce these minerals on Earth. A number of mechanisms have been proposed as models of Martian surface conditions and given the diversity of surface locations on Mars w...

With the development of intelligent coal mine construction, China’s production safety has been greatly improved, but gas explosion accidents still cannot be completely avoided and unsafe acts miners are an important cause accidents. Therefore, this study firstly collected 100 cases in China, improved framework human factors analysis classification system (HFACS) used it to identify causes miner...

Even in the context of smart mines, unsafe human acts are still an important cause coal mine gas explosion accidents, but there few models to analyze accidents. This study tries solve this problem through a risk assessment method accidents based on Human Factor Analysis and Classification system (HFACS-GE) Bayesian networks (BN). After verifying reliability HFACS-GE framework, BN model factors ...

Laboratory experiments were conducted to determine the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources. The prototype smoke detector combines optical scattering measurements with ionization chamber measurements in order to reduce/eliminate nuisance alarms due to the presence of airborn...

The article presents the analysis how actual coal dust explosion hazard is at distance of initial 200 metres safety zone maintained along entire length driven inclined drift II – face 567 in BRZESZCZE colliery, which was used during realization project titled Modelling mechanism explosive deposition vicinity mined faces terms identification, assessment and levelling possibility its financed by ...

Abstract In order to study the flame propagation characteristics and influencing factors of gas-coal dust mixed explosion in containers, this paper quantitatively explores effect mechanism two-phase concentration ratio closed section restraint mode on coupling by numerical simulation, comprehensively considering coal pyrolysis model mass heat transfer model. The current research results show th...
