PURPOSE: To determine if a six-week plyometric training intervention would significantly decrease valgus knee movement in post-pubescent, adolescent females. METHODS: Eighteen female subjects, ages 13-17, participated in pre- plyometric training intervention testing consisting of a 5-minute warm-up on a cycle ergometer, followed by 3-max vertical jumps using a Vertec™. Reflective markers were placed on the following right and left anatomical locations: anterior superior iliac spine (ASIS), center of patella, and lateral malleolus of fibula. Both pre- and post-testing max vertical jumps were recorded using a digital camera and analyzed using Kinovea™ software to identify valgus angles. Prior to post-testing, all participants completed a six-week (3 days/week) plyometric intervention program. Throughout training sessions, participants were provided specific coaching cues in order to reduce valgus motion, as well as other incorrect mechanics. Training consisted of similar exercises: depth jumps, jump and reach, power skips. Intensity increased throughout training. Following the six-week plyometric training intervention, participants completed post-testing, consistent with pre-testing methods. Data were analyzed using an alpha value ofp\u3c 0.05. RESULTS: Significant differences were present in valgus knee angles, p= 0.001. Means were calculated for pre- (M = 27.9 degrees) and post- (M = 12.9 degrees) valgus angles. There were no significant differences in participant max vertical jumps ( p= 0.430). Means were calculated for pre- (M = 16.03 inches) and post- (M = 16.67 inches) max vertical jump height. However, 12 of 18 (66.7%) participants increased their vertical jump height. CONCLUSION: The results propose that the plyometric intervention training had a significant decrease on valgus knee angles, but did not significantly increase vertical jump height.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Wuchsformen in Rasengesellschaften am Südfuß des Schweizer Juras
No full textDie Physiognomie einiger Pflanzengesellschaften am Südfuß des Schweizer Juras zwischen Biel und Neuenburg wurde im Feld an jeweils mehreren Beständen nach verschiedenen Gesichtspunkten erfasst: Wuchsformen der vorhandenen Pflanzen in einer etwas feineren Differenzierung als bei ELLENBERG & MUELLER-DOMBOIS (1966), Blattformen und -größen, Behaarung, Skleromorphie, Sukkulenz. Diese Daten wurden analog wie in pflanzensoziologischen Tabellen dargestellt und ausgewertet. An Stelle der Arten stehen hier die Wuchsformen-, Blatt- und Behaarungstypen.
Anhand dieser physiognomischen Tabelle lassen sich die Vegetationstypen folgendermaßen charakterisieren: (a) Wiese (Dauco-Salvio-Mesobrometum): hochwüchsige, dichtgeschlossene Bestände mit meist großblättrigen Arten; viele Gräser. (b) Weide (Alchemillo-Cynosuretum): ähnliche Wuchsformen und Blattgrößen wie in der Wiese. Auffälligere Herdenbildung durch niederliegende wurzelnde Pflanzen; viele Arten mit Stacheln und Dornen, Vorkommen von Gehölzen. (c) Halbtrockenrasen (Teucrio-Mesobrometum): Ziemlich geschlossene, artenreiche und vielschichtige Bestände; große Vielfalt der Wuchsformen und Blattgrößen; hochwüchsige Arten, auffällig mosaikartig wachsend. (d) Trockenrasen (Teucrio-Xerobrometum): Lückige, niedrigwüchsige Rasen; einzelne Arten nur schwach ineinander verflochten, oft geschlossene Herden bildend. Blätter meist klein. Wuchsformen der Felsgesellschaften (Polsterpflanzen, Sukkulente) hinzutretend. (e) Bestände auf Felsgrus und Felsplatten (Alysso-Sedion): Niedrigwüchsige, kaum geschichtete Bestände von geringer Krautdeckung, dafür mit hohem Anteil von Moosen und Flechten. Wichtige Wuchsformen: Sukkulente, Polsterförmige Pflanzen und Rosettenpflanzen. Viele plagiotrop wachsende Arten; auch die Blätter meist flach zur Sonne gerichtet, klein, mit besonderem Verdunstungsschutz (Sukkulenz, Nadeln, Blattränder eingerollt, bläuliche Farbe usw.).
Anhand von Aufrissen der Vegetation entlang von 1 m langen Transekten werden die Vegetationstypen veranschaulicht.The physiognomy of some plant associations was described for several stands in terms of: growth-forms of all plants (differentiated somewhat more accurately than by ELLENBERG & MUELLER-D0MB0IS 1966), leaf forms and size, trichomes, scleromorphy, succulence. These data are presented in analogy to phytosociological tables. Instead of species, growth-form, leaf and trichome types have been noted.
The resulting associations may be characterized as follows:
(a) Meadow (Dauco-Salvio-Mesobrometum): Tall, densely closed stands with many relatively big leaves and many grasses. (b) Pasture (Alchemillo-Cynosuretum): Quite similar to meadow, but with more patches of creeping and rooting plants; many species with spines; woody plants occurring. (c) Mesoxerophytic meadow (Teucrio-Mesobrometum): Quite dense stands with many species, rich in growth forms and different leaf sizes; tall plants in patches. (d) Xerophytic meadow (Teucrio-Xerobrometum): Open and low stands, the plants often in closed patches; leaves usually small; growth forms of rocky habitats occurring. (e) Scree heath (Alysso-Sedion): Low stands, open, with many mosses and lichens; important growth-forms: succulents, plants with rosettes and cushion plants; leaves small, with protection against transpiration.
