Recent achievements in sunlight concentration techniques have increased the potential of solar power as a viable source of renewable energy. Through its critical analysis of current methods, Photovoltaic Conversion of Concentrated Sunlight provides a comprehensive treatment of the issues involved in the creation of an efficient and cost-effective sustainable power resource. The authors introduce significant new original research and offer an insight into previously inaccessible Russian studies. Logically structured, the text presents both theoretical and practical advances in the field. Features include:<br> * Discussion of fabrication problems for both terrestrial and space photovoltaic installations<br> * Investigation of the impact of resistive losses on the operation of solar cells and new procedures for measuring components of internal resistance<br> * Explanation of the semiconductor physics underlying photovoltaics<br> * Examination of the most efficient concentrator solar cell structures and materials plus exploration of ways to improve cell performance<br> * Original theoretical and experimental results on luminescence phenomena in concentrator cells<br> * Useful measurement techniques for the determination of diagnostic cell parameters<br> * Analysis of energy characteristics of photovoltaic installations with high and low concentration ratios<br> An invaluable asset to industrialists and academics concerned with semiconductors and photovoltaics, this book will also serve environmental scientists through its examination of the problems associated with large-scale use of this ecological technology.

As humans ventured into the twentieth century, the industrialized countries were confronted with the scourge of rickets. Although solariums were becoming common in the early 1900s and phototherapy was gaining popularity as a result of the awarding of a Nobel Prize to Finsen in 1903, it wasn't until 1921 when Hess and Unger demonstrated that rickets could be cured by exposure to sunlight that the healthful benefit of sun exposure appreciated. In 1941, Apperly (Cancer Research; 1: 191-195, 1941) noted that the occasional increased risk of skin cancer was associated with a decreased risk of many other more common and serious cancers. The alarming increase in the number of cases of skin cancer, especially melanoma, has caused great concern about the negative role of sunlight in health. The Sixth International Arnold Rikli Symposium on the Biologic Effects of Light was held in Boston, Massachusetts from June 16th - 18th, 2001. The goal of this Symposium was to focus on the very popular practice of tanning either by sunlight or by artificial light sources and the overall impact this practice has on health and disease. The program was organized by members of the Scientific Advisory Committee and my co-chair emeritus, Professor Ernst G. Jung. The Program Committee organized an outstanding state-of-the-art program that was enthusiastically received by the participants.

The XIIlth General Assembly of the International Astronomical Union, held in Prague from 22 to 31 August, 1967, brought together more than 1800 active astron- omers from 40 countries. The agenda of the Assembly ranged from administrative questions to highly intricate scientific problems. Thirty-eight Presidents of the IAU Commissions contributed by their reports to a detailed survey of Astronomy for the period 1964-67. These reports were published in the Transactions of the IAU, Volume XIIIA. Transactions volume XIIIB bring the results of the administrative meetings and of the meetings of Commissions held during the General Assembly. The present volume is devoted to the most important scientific results of the General Assembly as presented in the Invited Discourses, Joint Discussions, and at Special Meetings. It is an established policy of the Union to invite prominent astronomers to hold, during the General Assembly, formal discourses on topics of major importance due to recent significant developments. These Invited Discourses cover, as a rule, broad fields of astronomical interest and are meant to give basic information also to scien- tists from other branches. Subjects which call for a more detailed technical approach are dealt with in the Joint Discussions or at Special Meetings. Here, invited speakers present authoritative surveys complemented by communications on current or envisaged projects. The proceedings of two other meetings, on Moon Probes and on Coordination of Solar Observations Made at Ground-based Observatories and with Space Vehicles, are of a sufficiently wide interest to warrant the inclusion into this volume.


How To Apply For A Solar Microfit In Ontario

RRP $13.99

With the price of solar components on a steady decline over the past 10 years, there has never been a better time to take part in the Government of Ontario's solar Feed In Tariff program (FIT, or microFIT). Through my years of education in alternative energy, trained as an Alternative Energy Engineering Technologist, and then working for the past five years in the booming solar industry in Ontario, I have heard from many people that the reason that they don't proceed with a solar installation is because of the paperwork involved. This book is designed to show the entire process, step by step, to make it simple to apply for and obtain an application approval for a microFIT contract offer with the Independent Electrical Safety Operators (IESO), formerly known as the Ontario Power Authority (OPA) prior to 2015.

Ben Palmer-Brown's Tales from the sacred mist is a brief collection of opinions based on observing society. After reading Tales from the sacred mist we want the reader to realise that small personal changes can lead to self-improvement. We hope Tales from the sacred mist will enliven the reader to view their life and the world around them differently. A short extract: "For as much as we have suffered..." (page 18) Alternatively," May love give us the courage to overcome..." (page 20) The bold words reinforce the non-bold words and illustrate an opposing view. Tales from the sacred mist covers diverse subjects from age through to health, love and self-mastery. Tales from the sacred mist welcomes all, from beginner to advance. We want Tales from the sacred mist to encourage the reader to start their journey of self-discovery and help those who are already there...
