A 4-H horse contest guide for a ranch horse competition. Contains descriptions of six classes: Ranch Horse Showmanship, Working Ranch Horse, Ranch Horse Trail, Cow Working, Roping, and Identification and Skills test. It also includes sample patterns and/or score sheets for most classes listed above.
This 4-H member manual begins with a short history of the American Western cowboy, and includes descriptions of and brief instructions for maneuvers a well-trained ranch horse can do; working, caring for, and branding or tagging cattle; and practical roping for ranch work.
This publication is adapted from 4-H Beef Project, originally prepared by Dean Frischknecht, Extension animal scientist emeritus; Guy Reynolds, Extension veterinarian emeritus; and Duane P. Johnson, Extension specialist, 4-H and Youth Development.

Gear technologists have, in recent years, developed rigid sorting grids, Sort-X, in bottom trawls, to improve the size selectivity of this type of gear. Experiments with the Sort-X system in the aft sections of trawls were carried out aboard Norwegian and Russian trawlers along the coast of Northern Norway and...
Anthropogenic modification watersheds and climate change have altered export from fluvial systems causing changes to the carbonate chemistry of river-influenced near shore environments. To determine the possible effects of riverine discharges on the mussel Perumytilus purpuratus, we performed in situ transplant experiments between river-influenced and open coastal habitats with contrasting...
Carpogenic germination of sclerotia and infection of flowers by ascospores of Sclerotinia minor is rare and seldom documented in most hosts. During 2007–2009, S. minor isolates were obtained from surface-sterilized pyrethrum flowers collected from fields in Australia. The isolation frequency of S. minor from flowers in 2007, 2008 and 2009...

Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investigated within an empirical framework. Here we attempt to delimit species boundaries in a closely related Glade of lichen-forming fungi...
Large ignimbrite flare-ups provide records of profound crustal modification during batholith formation at depth. The locations of source calderas and volumes and ages of the eruptions must be determined to develop models for the tectonomagmatic processes that occur during these events. Although high-precision isotopic ages of the ignimbrites are critical,...
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions.
First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...
