Gill The Wild Plants of the Burren & the Aran Islands
The Burren and the Aran Islands are renowned worldwide for their beautiful wild flowers and plants. Charles Nelson has selected 136 of the most widely occurring plus a number of special plants. By illustrating each plant with a colour photograph, showing it in the wild alongside space to record the place and date of discovery, this becomes a souvenir of rambles in search of wild flowers. Introduced by short chapters on the region plus user instructions, the photographs are grouped according to flower colour and pages are colour-coded so one can flick to the appropriate section.

Taylor & Francis Inc High-Frequency and Microwave Circuit Design
An integral part of any communications system, high-frequency and microwave design stimulates major progress in the wireless world and continues to serve as a foundation for the commercial wireless products we use every day. The exceptional pace of advancement in developing these systems stipulates that engineers be well versed in multiple areas of electronics engineering. With more illustrations, examples, and worked problems, High-Frequency and Microwave Circuit Design, Second Edition provides engineers with a diverse body of knowledge they can use to meet the needs of this rapidly progressing field.The book details the modulation and demodulation of circuits and relates resonant circuits to practical needs. The author provides a logical progression of material that moves from medium frequencies to microwave frequencies. He introduces rectangular waveguides as high-pass devices and explains conditions under which dielectric breakdown may limit the amount of power that may be transmitted in a completely expanded chapter. The section on antennas is completely updated to demystify the useful characteristic of antennas and relate their performance to the requirements of digital communication systems. Exploring the latest developments in communications engineering, this reference outlines a variety of topics using sufficient mathematical derivations and provides an overview of the concepts engineers need to understand current technologies and develop those of the future.
