How Nicola Tesla’s theory of resonance supersedes Faraday’s ‘Law of Electrolysis’ and has been used to release hydrogen and oxygen efficiently from water to run engines on an endless supply of carbon-free fuel. Who used it (including two NASA engineers), how it works and how it can supply all our energy needs. This book assumes no technical knowledge, cutting through the jargon step-by-step, but also has links to many sources of information, including patents, scientific reports and online information for the reader to pursue further. Hydrogen does not pollute, there are massive amounts of it in water and we do not need to store it if we make it on-demand. This process does not break any laws of science, which is a popular myth. This book explains how easy it is to release from abundant water, in a super-efficient process using inexpensive materials and components.

The Kenya Gazette is an official publication of the government of the Republic of Kenya. It contains notices of new legislation, notices required to be published by law or policy as well as other announcements that are published for general public information. It is published every week, usually on Friday, with occasional releases of special or supplementary editions within the week.

Revised to reflect recent advances in technology, this is a course for intermediate and advanced typing / word-processing programmes. It includes photocopiable documents for completion of the exercises, as well as displayed answers to all exercises not already set out in the main text. In this edition extra information and exercises are included on language arts skills which include a punctuation review, the use of prepositions, subject and verb agreement, word comparisons such as accept/except and advice/advise.

Bradford Hill has defined a clinical trial as "A carefully and ethically designed experiment with the aim of answering some precisely framed question" [1]. This definition specifies a careful design and requires the provision of adequate controls. Random allocation of treatments to subjects is important to ensure is entitled that the treated and control groups are similar. Therefore this book Randomised Controlled Clinical Trials. We can define a randomised controlled trial by rewriting Bradford Hill's definition as follows, "A carefully and ethi cally designed experiment which includes the provision of adequate and ap propriate controls by a process of randomisation, so that precisely framed questions can be answered. " I am a firm advocate ofRandomised Controlled Clinical Trials but intend to give a balanced view of the advantages and disadvantages of these ethical experiments. This book is directed primarily at the medical research worker, although certain chapters may find a wider application. When discussing a randomised controlled trial, it is neither practicable nor desirable to divorce theory from practice, however the first ten chapters con centrate mainly on theory, and the remainder focus on practice. The segment on trial design is followed by sections on writing the protocol, designing the forms, conducting the trial, and analysing the results. This book is meant to serve both as a reference manual and a practical guide to the design and performance of a trial.
