Plant Drug Analysis A Thin Layer Chromatography Atlas


Free Download Plant Drug Analysis: A Thin Layer Chromatography Atlas By Sabine Bladt
1996 | 399 Pages | ISBN: 3540586768 | PDF | 117 MB
This second edition of Plant Drug Analysis includes more than 200 updated color photographs of superb quality demonstrating chromatograms of all relevant standard drugs. All drugs presented meet the standard of the official pharmacopoeia and originate from well-defined botanical sources. With this guide the technique of thin layer chromatography can be easily used without previous pharmacognostic training. Only commercially available equipment and reagents are needed, the sources as well as all practical details are given. From the reviews "…should not be missed in any laboratory dealing with crude drug analysis" trends in analytical chemistry "…a unique and remarkable collection…an invaluable guide" Phytochemistry "The color photographs…are unbelievably well done" Analytical Biochemistry "…a required text for any laboratory concerned with the analysis of medicinal plant products" Irish Pharmacy Journal

Chemistry and Radiation Changes in the Ozone Layer


Free Download Chemistry and Radiation Changes in the Ozone Layer By P. J. Crutzen (auth.), Christos S. Zerefos, Ivar S. A. Isaksen, Ioannis Ziomas (eds.)
2000 | 398 Pages | ISBN: 0792365143 | PDF | 13 MB
Recent studies have demonstrated a link between ozone changes caused by human activities and changing UV levels at the Earth’s surface, as well as a link to climate through changes in radiative forcing and links to changes in chemical composition. This book draws together key scientists who provide state of the art contributions on the variable ozone layer and the interplay of longwave and shortwave radiative interactions which link ozone, the climate and UV issues.

Layer Signals A Practical Guide for Layer Focused Management


Free Download Monique Bestman, Marko Ruis, Jos Heijmans, "Layer Signals: A Practical Guide for Layer Focused Management"
English | 2013 | ISBN: 9087401248 | PDF | pages: 18 | 13.2 mb
‘Laying hens are not egg laying machines. Proper care requires knowledge of the animal and the capability to use this in practice. For optimal results.’ Not all poultry farmers maximise the full potential of their birds. Both kept in cage or floor systems, for a good performance during the production period, the management should be correct and efficient. But how do you know that what you are doing is right? Your chickens continuously send out signals: about their health, how well they know their way around their surroundings and whether they feel happy and comfortable. Do you recognise the signals your chickens are giving? Do you know the difference between abnormal, runny droppings and healthy caecal droppings? Are you able to identify abnormalities of the egg and trace this back to the cause? And do something about it? If you recognise the signs that point to potential problems, then make sure you are armed with information to take the appropriate steps to get your flock back on track. But to do so, you must know all the ins and outs of your own farm and be able to assess the impact these changes will have on your animals. Laying Hens is a practical guide that shows you how to pick up the signals given by your animals at an early stage, how to interpret them and which action to take. Poultry Signals presents practical knowledge of animal oriented poultry farming in an easy, accessible format.

Fundamentals of Boundary-Layer Meteorology


Free Download Fundamentals of Boundary-Layer Meteorology by Xuhui Lee
English | PDF EPUB (True) | 376 Pages | ISBN : 3031326679 | 33.3 MB
This book is filled with didactic elements such as exercises, charts and case study examples. It introduces a set of fundamental equations that govern the conservation of mass (dry air, water vapor, trace gases), momentum and energy in the lower atmosphere. It offers students an up-to-date literature overview and introduces theory to a field that is mostly empirical in nature. Dedicated to undergraduate or graduate students in atmospheric sciences and meteorology, this textbook compels students about the importance of the subject and its application.

Quantum Communication The Physical Layer of Future Optical Networks


Free Download Quantum Communication The Physical Layer of Future Optical Networks (208 Pages)
by Mahdi Hosseini

English | 2023 | ISBN: 9811279055 | 209 pages | True PDF | 34.29 MB
This book is the second volume in the series New Era Electronics, a compilation of lecture notes defining the important concepts tied to the electronics transition happening in the 21st century. Quantum communication is introduced in this volume through the coverage of relevant, basic concepts of quantum mechanics and the introduction of quantum elements of a quantum optical communication system. Also included is a quantum description of electromagnetic fields and its interaction with atoms to generate, store, measure and control quantum optical information encoded onto optical fields. By taking a conceptual and less mathematical approach to quantum optics and quantum information, this book becomes accessible to broader audiences and engineers working actively in the technical field. The reader is only required to have a basic understanding of undergraduate linear algebra.
