English Version Translated into ChineseForty years of experience in the laboratory fume hood industry told Chip Albright that something was wrong. Albright was compelled to write this book after hearing the callous comment, "It doesn't matter if the hoods work, it only matters that we have them and that people assume they work." Observing hundreds of laboratories around the world exposed the fact that the fume hood is the most misunderstood and misused safety device in most laboratories. People who work in laboratories assume they are being protected from harmful air contaminants - but, are they?Until now, understanding the complexity of laboratory ventilation systems was a nearly impossible feat for most. This book takes a step by step approach to explaining the interface between the fume hood, the laboratory ventilation system and the building HVAC. It reveals not only the failings of these systems, but suggests solutions for making them better. Finally, a single source that includes:?the history of the fume hood?a detailed explanation of how a fume hood works?why most fume hoods do not perform effectively?why all laboratory users should be concerned?how to ensure that your laboratory fume hood is actually keeping your laboratory safeAlbright's holistic approach to the subject is refreshing and effective. This book will leave you with a deeper understanding of the science behind fume hoods and heightened awareness of how they can protect the people in a laboratory. If you own or work in a laboratory, this book is required reading. More Info: https://laboratoryfumehoodsexplained.com/
This document specifies the technical requirements for air performance, noise, odor reduction, grease absorption factor of range hoods and other cooking fume extractors (hereinafter referred to as "appliances"), which have a rated voltage not exceeding 250 V; describes the corresponding inspection rules, test methods; specifies the content of marking, packaging, transportation, storage, etc.; at the same time provides product classification for technical requirements. This document does not cover: - Appliances installed for industrial and commercial purposes; - Appliances installed in special places, such as where corrosive or explosive gases (dust, steam or flammable gases) are present.
This is the story of LSD told by a concerned yet hopeful father, organic chemist Albert Hofmann, Ph.D. He traces LSD's path from a promising psychiatric research medicine to a recreational drug sparking hysteria and prohibition. In LSD: My Problem Child, we follow Dr. Hofmann's trek across Mexico to discover sacred plants related to LSD, and listen in as he corresponds with other notable figures about his remarkable discovery. Underlying it all is Dr. Hofmann's powerful conclusion that mystical experiences may be our planet's best hope for survival. Whether induced by LSD, meditation, or arising spontaneously, such experiences help us to comprehend "the wonder, the mystery of the divine, in the microcosm of the atom, in the macrocosm of the spiral nebula, in the seeds of plants, in the body and soul of people." More than sixty years after the birth of Albert Hofmann's problem child, his vision of its true potential is more relevant, and more needed, than ever.
A respected resource for decades, the Guide for the Care and Use of Laboratory Animals has been updated by a committee of experts, taking into consideration input from the scientific and laboratory animal communities and the public at large. The Guide incorporates new scientific information on common laboratory animals, including aquatic species, and includes extensive references. It is organized around major components of animal use: Key concepts of animal care and use. The Guide sets the framework for the humane care and use of laboratory animals. Animal care and use program. The Guide discusses the concept of a broad Program of Animal Care and Use, including roles and responsibilities of the Institutional Official, Attending Veterinarian and the Institutional Animal Care and Use Committee. Animal environment, husbandry, and management. A chapter on this topic is now divided into sections on terrestrial and aquatic animals and provides recommendations for housing and environment, husbandry, behavioral and population management, and more. Veterinary care. The Guide discusses veterinary care and the responsibilities of the Attending Veterinarian. It includes recommendations on animal procurement and transportation, preventive medicine (including animal biosecurity), and clinical care and management. The Guide addresses distress and pain recognition and relief, and issues surrounding euthanasia. Physical plant. The Guide identifies design issues, providing construction guidelines for functional areas; considerations such as drainage, vibration and noise control, and environmental monitoring; and specialized facilities for animal housing and research needs. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities. This updated and expanded resource of proven value will be important to scientists and researchers, veterinarians, animal care personnel, facilities managers, institutional administrators, policy makers involved in research issues, and animal welfare advocates.
The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.
