Wood has played a major role throughout human history. Strong and versatile, the earliest humans used wood to make shelters, cook food, construct tools, build boats, and make weapons. Recently, scientists, politicians, and economists have renewed their interest in wood because of its unique properties, aesthetics, availability, abundance, and perhaps most important of all, its renewability. However, wood will not reach its highest use potential until we fully describe it, understand the mechanisms that control its performance properties, and, finally, are able to manipulate those properties to give us the desired performance we seek. The Handbook of Wood Chemistry and Wood Composites analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood. They emphasize the mechanisms of reaction involved and resulting changes in performance properties including modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating decades of teaching experience, the editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.
Proudly serving the scientific community for over a century, this 96th edition of the CRC Handbook of Chemistry and Physics is an update of a classic reference, mirroring the growth and direction of science. This venerable work continues to be the most accessed and respected scientific reference in the world. An authoritative resource consisting of tables of data and current international recommendations on nomenclature, symbols, and units, its usefulness spans not only the physical sciences but also related areas of biology, geology, and environmental science. The 96th edition of the Handbook includes 18 new or updated tables along with other updates and expansions. A new series highlighting the achievements of some of the major historical figures in chemistry and physics was initiated with the 94th edition. This series is continued with this edition, which is focused on Lord Kelvin, Michael Faraday, John Dalton, and Robert Boyle. This series, which provides biographical information, a list of major achievements, and notable quotations attributed to each of the renowned chemists and physicists, will be continued in succeeding editions. Each edition will feature two chemists and two physicists. The 96th edition now includes a complimentary eBook with purchase of the print version. This reference puts physical property data and mathematical formulas used in labs and classrooms every day within easy reach.

ظل يُقال لنا طيلة عشرات السنوات إن التفكير الإيجابي هو المفتاح إلى حياة سعيدة ثرية. لكن مارك مانسون يشتم تلك " الإيجابية " ويقول: " فلنكن صادقين، السيء سيء وعلينا أن نتعايش مع هذا ". لا يتهرّب مانسون من الحقائق ولا يغفلها بالسكّر، بل يقولها لنا كما هي: جرعة من الحقيقة الفجِّة الصادقة المنعشة هي ما ينقصنا اليوم. هذا الكتاب ترياق للذهنية التي نهدهد أنفسنا بها، ذهنية " فلنعمل على أن يكون لدينا كلنا شعور طيب " التي غزت المجتمع المعاصر فأفسدت جيلًا بأسره صار ينال ميداليات ذهبية لمجرد الحضور إلى المدرسة. ينصحنا مانسون بأن نعرف حدود إمكاناتنا وأن نتقبلها. وأن ندرك مخاوفنا ونواقصنا وما لسنا واثقين منه، وأن نكفّ عن التهرب والفرار من ذلك كله ونبدأ مواجهة الحقائق الموجعة، حتى نصير قادرين على العثور على ما نبحث عنه من جرأة ومثابرة وصدق ومسؤولية وتسامح وحب للمعرفة. لا يستطيع كل شخص أن يكون متميزًا متفوقًا. ففي المجتمع ناجحين وفاشلين؛ وقسم من هذا الواقع ليس عادلًا وليس نتيجة غلطتك أنت. وصحيح أن المال شيء حسن، لكن اهتمامك بما تفعله بحياتك أحسن كثيرًا؛ فالتجربة هي الثروة الحقيقية. إنها لحظة حديث حقيقي صادق لشخص يمسكك من كتفيك وينظر في عينيك. هذا الكتاب صفعة " منعشة لهذا الجيل حتى تساعده في عيش حياة راضية مستقرة.
These recommendations have been developed in the light of technical progress, the advent of new substances and materials, the exigencies of modern transport systems and, above all, the requirement to ensure the safety of people, property and the environment. They are addressed to governments and international organisations concerned with the regulation of the transport of dangerous goods. The Model Regulations cover the classification of dangerous goods, their listing, the use, construction, testing and approval of packagings and portable tanks, as well as consignment procedures such as marking, labeling, placarding and documentation. This sixteenth revised edition contains new provisions (e.g. transport of substances which are toxic by inhalation, requirements for metal hydride storage systems, provisions for fuel cell engines, use of open cryogenic receptacles) and revised provisions (e.g. transport of dangerous goods packed in limited quantities, classification criteria for environmentally hazardous substances, use of electronic data interchange transmission techniques and special provisions for fumigated cargo transport units)."
