According to the new classification method, salt mines and underground work or areas where methane has not been observed but for which in boreholes found rock massifs are considered be fire / mine mining work. This allows only effective of exploitation maintained wire regime, rest being non-wire. The purpose this paper is determine rate (explosive gas) carbon dioxide (oxidizing operations Tg-Oc...

Reading comprehension is a challenging task, especially when executed across longer or across multiple evidence documents, where the answer is likely to reoccur. Existing neural architectures typically do not scale to the entire evidence, and hence, resort to selecting a single passage in the document (either via truncation or other means), and carefully searching for the answer within that pas...

This contribution comments on certain works of digital literature in order to demonstrate their use of formal and thematic literary techniques and show that ‘wreaders’ have their own creative pattern. Playing with hyperlinks involves disorganized thinking, associative laxity and conceptual, and linguistic alterations that infringe the linear construction of the literary paradigm. The mechanism ...

Purpose – This paper aims to assess the usability of electronic books (e-books) and paper books (p-books) with objective measures, including user comprehension, eye fatigue, and perception. Design/methodology/approach – A total of 56 sixth-year public school students participated in this study. This paper was conducted in the following order: pre-CFF measurement, p-/e-book reading, post-CFF mea...

The collected works of English mathematics educator, Mary Boole, might be invaluable for education and curriculum research that attempts to understand the question: “what counts as knowing?” Even though it was written before 1916, Boole’s work allows curriculum researchers and teacher educators interested in the question to experience a significant shift in thinking. For example, in the followi...

OBJECTIVES Radon concentrations for 31 Polish underground tourist routes were analyzed. The equivalent dose to the lung, the effective dose and the relative risk were calculated for employees of the analyzed routes on the grounds of information on radon concentrations, work time, etc. MATERIAL AND METHODS The relative risk for lung cancers was calculated using the Biological Effects of Ionizi...

Fatal accidents associated with underground coal mines require the implementation of high-level gas monitoring and miner’s localization approaches to promote underground safety and health. This study introduces a real-time monitoring, event-reporting and early-warning platform, based on cluster analysis for outlier detection, spatiotemporal statistical analysis, and an RSS range-based weighted ...

Wireless underground sensor networks (WUSNs) consist of buried nodes, which are connected to subsurface underground sensors, and use electromagnetic (EM) waves for underground communications. WUSNs are capable of operating in environments where no other computer network has functioned before, and has the potential to provide real-time, robust, and energy efficient sensing, and communication in ...

A review of literature related to fire evacuation in underground transportation systems, e.g., tunnels and subway stations, was carried out with the objectives (1) to identify a theoretical framework that can help understand of human behaviour in the event of a fire in underground transportation systems, (2) to use the theoretical framework to analyse and to identify problems related to fire ev...
