Sommario/riassunto |
|
All In a Day's Work will help you give students an exciting and varied look into the future, and the role played by an education in the sciences as a foundation for some of the world's most fascinating jobs. The book is a compendium of more than 30 of the popular "Career of the Month" columns from the NSTA high school member journal The Science Teacher. Each column profiles people in science-related jobs and is designed to be reproduced and shared with your high school students as they formulate future career and education plans. |

Sommario/riassunto |
|
The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensable resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on |
