Download E-books The Chemistry of Alchemy: From Dragon's Blood to Donkey Dung, How Chemistry Was Forged PDF

By Cathy Cobb, Harold Goldwhite

A special approach to the background of technological know-how utilizing  do-it-yourself experiments in addition to short old profiles to illustrate how the traditional alchemists stumbled upon the technological know-how of chemistry.

Be the alchemist! discover the legend of alchemy with the technology of chemistry. take pleasure in over twenty hands-on demonstrations of alchemical reactions. 

In this exploration of the traditional paintings of alchemy, 3 veteran chemists express that the alchemists' quest concerned genuine technological know-how and so they recount interesting tales of the sages who played those unusual experiments.

Why waste extra phrases in this bizarre deviation within the evolution of chemistry? because the authors convey, the writings of medieval alchemists could seem just like the ravings of brain-addled fools, yet there's extra to the tale than that.

Recent scholarship has proven that a few doubtless nonsensical mysticism is, in reality, decipherable code, and Western eu alchemists functioned from a more impregnable theoretical beginning than formerly notion. that they had a guideline, in keeping with adventure:  separate and purify fabrics via fireplace and reconstitute them into items, together with, in fact, gold and the common elixir, the Philosophers' stone.

Their efforts weren't in useless:  by trial, by means of errors, by way of layout, and by means of endurance, the alchemists came across acids, alkalis, alcohols, salts, and delightful, strong, and colourful reactions--which might be reproduced utilizing universal items, minerals, metals, and salts.  

So assemble your vats and stoke your fires! prepare to make burning waters, peacocks' tails, Philosophers' stone, and, after all, gold!

Download E-books Intelligent Drug Development: Trials and Errors in Clinical Research PDF

By Michael Tansey

Scientific study is seriously regulated and contains coordination of various pharmaceutical-related disciplines. every one person trial consists of contractual, regulatory, and ethics approval at each one web site and in each one nation. medical trials became so advanced and executive standards so stringent that researchers frequently technique trials too carefully, confident that the method is sure to be insurmountably complex and riddled with roadblocks. A step again is required, an goal exam of the drug improvement method as an entire, and suggestions made for streamlining the method in any respect stages.
With Intelligent Drug Development, Michael Tansey systematically addresses the main parts that have an effect on the standard, timeliness, and cost-effectiveness of the drug-development technique, and identifies steps that may be adjusted and made extra effective. Tansey makes use of his personal studies engaging in scientific trials to create a consultant that gives versatile, adaptable methods of imposing the required procedures of improvement. in addition, the approaches defined within the publication are usually not based both on a specific corporation constitution or on any particular know-how; hence, Tansey's strategy could be applied at any corporation, despite measurement. The e-book comprises particular examples that illustrate a number of the ways that the rules should be utilized, in addition to feedback for offering a greater context during which the alterations could be carried out. The protocols for drug improvement and medical learn have grown more and more advanced in recent times, making clever Drug Development a wanted exam of the pharmaceutical process.
