Intro to Archery
INTRODUCTION TO ARCHERY TARGET ARCHERY This the most commonly practiced form of archery worldwide and is practiced within most Archery Australia clubs. Target tournaments are conducted regularly and held both indoors and outdoors. Shooting distances vary from 18 metres (indoor) to 90 metres (outdoor), with target sizes being 40 or 60 centimetres for indoors and either 80 or 122 centimetres for outdoors. Targets have five colours with each colour being divided into 2 to provide 10 scoring zones. The innermost ring is given a value of 10 points, down to the outermost ring with a value of 1 point. Target rounds involve shooting a set number of arrows over one or several distances. Indoor events involve shooting a total of either 30 or 60 arrows; with outdoor events shooting 72, 90, 120 or 144 arrows are shot. FIELD ARCHERY Field archery is a challenging outdoor discipline in which the archer takes on the terrain as well as the target. Field archery is a combination of archery, golf, and bush walking. A course is set up in a bush land setting taking advantage of hills, slopes, angles and light and shade. A field course is made up of either 24 or 28 targets depending on the round being shot. The archer is required to shoot either three or four arrows at each target. Distances range from 10 to 60 metres and target face sizes vary from 20 to 80 centimetres. CLOUT ARCHERY Clout archery is another popular discipline in Australia because due to its fun aspect. Clout archery is derived from medieval warfare where archers would lob arrows onto the advancing army. -
+1. Introduction 2. Cyrillic Letter Rumanian Yn
MAIN.HTM 10/13/2006 06:42 PM +1. INTRODUCTION These are comments to "Additional Cyrillic Characters In Unicode: A Preliminary Proposal". I'm examining each section of that document, as well as adding some extra notes (marked "+" in titles). Below I use standard Russian Cyrillic characters; please be sure that you have appropriate fonts installed. If everything is OK, the following two lines must look similarly (encoding CP-1251): (sample Cyrillic letters) АабВЕеЗКкМНОопРрСсТуХхЧЬ (Latin letters and digits) Aa6BEe3KkMHOonPpCcTyXx4b 2. CYRILLIC LETTER RUMANIAN YN In the late Cyrillic semi-uncial Rumanian/Moldavian editions, the shape of YN was very similar to inverted PSI, see the following sample from the Ноул Тестамент (New Testament) of 1818, Neamt/Нямец, folio 542 v.: file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 1 of 28 MAIN.HTM 10/13/2006 06:42 PM Here you can see YN and PSI in both upper- and lowercase forms. Note that the upper part of YN is not a sharp arrowhead, but something horizontally cut even with kind of serif (in the uppercase form). Thus, the shape of the letter in modern-style fonts (like Times or Arial) may look somewhat similar to Cyrillic "Л"/"л" with the central vertical stem looking like in lowercase "ф" drawn from the middle of upper horizontal line downwards, with regular serif at the bottom (horizontal, not slanted): Compare also with the proposed shape of PSI (Section 36). 3. CYRILLIC LETTER IOTIFIED A file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 2 of 28 MAIN.HTM 10/13/2006 06:42 PM I support the idea that "IA" must be separated from "Я". -

Old Cyrillic in Unicode*
Old Cyrillic in Unicode* Ivan A Derzhanski Institute for Mathematics and Computer Science, Bulgarian Academy of Sciences [email protected] The current version of the Unicode Standard acknowledges the existence of a pre- modern version of the Cyrillic script, but its support thereof is limited to assigning code points to several obsolete letters. Meanwhile mediæval Cyrillic manuscripts and some early printed books feature a plethora of letter shapes, ligatures, diacritic and punctuation marks that want proper representation. (In addition, contemporary editions of mediæval texts employ a variety of annotation signs.) As generally with scripts that predate printing, an obvious problem is the abundance of functional, chronological, regional and decorative variant shapes, the precise details of whose distribution are often unknown. The present contents of the block will need to be interpreted with Old Cyrillic in mind, and decisions to be made as to which remaining characters should be implemented via Unicode’s mechanism of variation selection, as ligatures in the typeface, or as code points in the Private space or the standard Cyrillic block. I discuss the initial stage of this work. The Unicode Standard (Unicode 4.0.1) makes a controversial statement: The historical form of the Cyrillic alphabet is treated as a font style variation of modern Cyrillic because the historical forms are relatively close to the modern appearance, and because some of them are still in modern use in languages other than Russian (for example, U+0406 “I” CYRILLIC CAPITAL LETTER I is used in modern Ukrainian and Byelorussian). Some of the letters in this range were used in modern typefaces in Russian and Bulgarian. -

Principles of Archery Range Architecture a Redesign of the Yolo Bowmen South Range
Principles of Archery Range Architecture A Redesign of the Yolo Bowmen South Range Devin Caprari June 13, 2008 Principles of Archery Range Architecture: A Redesign of the Yolo Bowmen South Range A Senior Project Presented to the Faulty of the Landscape Architecture Department University of California, Davis In Partial Fulfillment of the Requirement for the Degree of Bachelors of Science of Landscape Architecture Accepted and Approved by: ________________________________________ Faculty Committee Member, Steve Greco ________________________________________ Committee Member, Christine Alford ________________________________________ Faculty Sr. Project Advisor, Robert Thayer Devin Caprari June 13, 2008 Abstract This project is an attempt to incorporate broader environmental design principles into the existing (and limited) body of literature concerning the design of field archery ranges. I have organized these design considerations into four principles that archery clubs and land planners can utilize. Observing sensitivity to the environment, providing a layout for safe shooting, making the space comfortable, and programming inclusive spaces makes a range that serves its community well. These principles are to explain concisely how a range can be made not only to accommodate archers but also to exist harmoniously with neighboring land as well as function as a valuable community building asset. Finally, an example design treatment to the Yolo Bowmen Archery Range of Grasslands Regional Park will help to clarify the principles set forth in -
