Plastics Technology - Original PDF
نویسندگان: خلاصه: This introductory book covers the entire spectrum of plastics technology/engineering, from raw materials to finished plastic products. It is not just for university students in plastics technology and other engineering disciplines but also for beginners to the field in general. The interconnectivity between the different relevant knowledge areas of plastics technology, such as materials engineering, processing technology, and product development, is emphasized. A chapter "Plastics and the Environment" is also included, covering a topic often of great concern to students and newcomers to the field. Also includes numerous videos, conveniently linked via QR codes, to better demonstrate key processes visually.
Design of Injection Molded Plastic Parts - Original PDF
نویسندگان: خلاصه: This book creates a new perspective on the design of plastic parts. In many books there is a strong focus on the material, the material properties, and the calculation or dimensioning. What is often not taken into account is that very many plastic components only have to withstand low loads; in very many applications, the focus is on the actual design. This requires a good understanding of the injection molds that must be built to produce the plastic components. Depending on the design of the injection molded component, these molds become more complex and more prone to failure during production. The complex process of manufacturing a plastic part becomes holistically understandable as a link is created between the molder, the mold maker, and the part designer. The focus is on injection molds and therefore on thermoplastics. Everything that is necessary for the design and manufacture of an injection molded component is presented in a simple, extremely practical manner and limited to the essentials. Many descriptive pictures as well as examples based on the demonstration component "Polyman" facilitate the understanding enormously.
MOTHER TERESA - PDF
نویسندگان: خلاصه: In response to high school and public library needs, Greenwood developed this distinguished series of full-length biographies specifically for student use. Prepared by field experts and professionals, these engaging biographies are tailored for high school students who need challenging yet accessible biographies. Ideal for secondary school assignments, the length, format and subject areas are designed to meet educators’ requirements and students’ interests. Greenwood offers an extensive selection of biographies spanning all curriculum related subject areas including social studies, the sciences, literature and the arts, history and politics, as well as popular culture, covering public figures and famous personalities from all time periods and backgrounds, both historic and contemporary, who have made an impact on American and/or world culture. Greenwood biographies were chosen based on comprehensive feedback from librarians and educators. Consideration was given to both curriculum relevance and inherent interest. The result is an intriguing mix of the well known and the unexpected, the saints and the sinners from long-ago history and contemporary pop culture. Readers will find a wide array of subject choices from fascinating crime figures like Al Capone to inspiring pioneers like Margaret Mead, from the greatest minds of our time like Stephen Hawking to the most amazing success stories of our day like J.K. Rowling. While the emphasis is on fact, not glorification, the books are meant to be fun to read. Each volume provides in-depth information about the subject’s life from birth through childhood, the teen years, and adulthood. A thorough account relates family background and education, traces personal and professional influences, and explores struggles, accomplishments, and contributions. A timeline highlights the most significant life events against a historical perspective. Bibliographies supplement the reference value of each
