This book gathers selected papers from the 8th International Field Exploration and Development Conference (IFEDC 2019) and addresses a broad range of topics, including: Low Permeability Reservoir, Unconventional Tight & Shale Oil Reservoir, Unconventional Heavy Oil and Coal Bed Gas, Digital and Intelligent Oilfield, Reservoir Dynamic Analysis, Oil and Gas Reservoir Surveillance and Management, Oil and Gas Reservoir Evaluation and Modeling, Drilling and Production Operation, Enhancement of Recovery, Oil and Gas Reservoir Exploration. The conference not only provided a platform to exchange experiences, but also promoted the advancement of scientific research in oil & gas exploration and production. The book is chiefly intended for industry experts, professors, researchers, senior engineers, and enterprise managers.
Osteoporosis is a systemic skeletal disease, strongly affecting postmenopausal women and characterized by an increased risk of bone fragility and a decrease in bone mass. Bone homeostasis requires a balance between bone-forming osteoblasts and bone-resorbing osteoclasts. When this balance is impaired, normal bone remodelling cannot keep bone mass stable, leading to osteopenia and osteoporosis. About 30–50% of all women in the world suffer from fractures due to osteoporosis throughout their lives. The treatments include improving metabolic abnormalities through complementary and alternative therapies, drug application and surgical therapy for the management of overweight, obesity and hormone metabolism disorder. Chinese traditional medicine has been increasingly considered as an effective therapy for osteoporosis. A series of formulae, herbs and natural products have been indicated for their effects in the prevention and treatment of osteoporosis, such as Liu-Wei-Di-Huang Wan (formula), Morindae Officinalis Radix (herb), Longspur epimedium glycoside (natural product). However, the mechanisms of action remain largely unexplored.

She, who was born before her marriage, turned into a complete slut with the contempt and curses of the entire world. That damn stinky man ate her whole body, yet did not show himself. That night, she could still vaguely remember how he robbed and occupied her, how his neck interweaved with her hot body and his tempting breathing.
This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds. A theory of mode-locking, based on the optical noise concept, is discussed. With this approximation, all paradoxes of ultrashort laser pulse formation have been explained. The book includes examples of very delicate laser operation in biomedical areas and extremely high power systems used for material processing and water purification. We hope this book will be useful for engineers and managers, for professors and students, and for those who are interested in laser science and technologies.

Given the frequent movement of commercial plants outside their native location, the consistent and standard use of plant names for proper identification and communication has become increasingly important. This second edition of World Economic Plants: A Standard Reference is a key tool in the maintenance of standards for the basic science underlyin
