Book Description
Theoretical and technical problems of electromagnetic compatibility (EMC) in mining are covered in this volume. EMC is discussed in three main groups of problems: sources (generation) of interference, propagation of interference in mining conditions, the influence of interferences on mining devices, particularly electronic devices used in deep coal mines. Propagation of interference and its influence on mining communication and signalling systems as well as on control systems of mining machines are discussed. Attention is paid to the influences of interference on dispatching sytems which give to the dispatcher some information about mining hazards. The book will be of interest to mining and electrical engineers.

Book Description
Due to the increased use of radio-based systems and microprocessor controlled equipment in coal mines, the Office of Mine Safety and Health Research (OMSHR) is interested in identifying available practices, standards, and resources that can be adopted to reduce the potential for electromagnetic interference (EMI). Research performed under this contract identified possible EMI requirements for coal mining equipment to ensure proper operation of equipment used in mines with a view towards maximizing mine safety, and also identified potential commercial resources for improvement of EMC in underground coal mines.

Book Description
Veterinary Clinical Pathology: A Case-Based Approach presents 200 cases with questions for those interested in improving their skills in veterinary clinical pathology. It emphasises an understanding of basic pathophysiologic mechanisms of disease, differential diagnoses and recognition of patterns associated with various diseases or conditions. Topics discussed include haematology, clinical chemistry, endocrinology, acid-base and blood gas analysis, haemostasis, urinalysis, biological variation and quality control. Species covered include the cat, dog and horse, with additional material on ruminants. Cases vary in difficulty, allowing beginners to improve their clinicopathologic skills while more complicated cases, or cases treating unfamiliar topics, are included for experienced readers. This book is a helpful revision aid for those in training as well as for those in practice who are pursuing continuing education. It is also a valuable resource for veterinary nurses and technicians.

Book Description
Wireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.
