USING KINETIC ISOMETRIC MID-THIGH PULL VARIABLES TO PREDICT D-I MALE SPRINTERS’ 60M PERFORMANCE

The purpose of the study was to determine the relationship of isometric mid-thigh pull kinetic variables including: peak force (PF), instantaneous force at 50, 90, 200 and 250 milliseconds (F@50, 90, 200 and 250 ms) rate of force development (RFD@ 50, 90, 200 and 250 ms) and impulse at 50, 90, 200, and 250 ms (IP @ 50, 90, 200 and 250 ms) to college male sprinters’ 60 m running performance. Eleven NCAA Division I male sprinters participated in the study that included two testing sessions. The first session included sprint testing and the second session included isometric mid-thigh pull strength assessment. The results from current study indicated that explosive force production variables (F@ 50 ms, RFD @ 50 and 90 ms, IP @ 90 and 200 ms) showed strong correlations with 60 m running time and maximal running velocity; while the MPF was not related to sprint variables

Area-Wide Suppression of the Mediterranean Fruit Fly, Ceratitis capitata, and the Oriental Fruit Fly, Bactrocera dorsalis, in Kamuela, Hawaii

The United States Department of Agriculture's Agricultural Research Service initiated an area-wide fruit fly management program in Hawaii in 2000. The first demonstration site was established in Kamuela, Hawaii, USA. This paper documents suppression of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in a 40 km2 area containing urban, rural and agricultural zones during a 6 year period. The suppression techniques included sanitation, GF-120 NF Naturalyte Fruit Fly Bait sprays, male annihilation, Biolure® traps, and parasitoids against C. capitata and B. dorsalis. In addition, small numbers of sterile males were released against B. dorsalis. Substantial reductions in fruit infestation levels were achieved for both species (90.7 and 60.7% for C. capitata and B. dorsalis, respectively) throughout the treatment period. Fruit fly captures in the 40 km2 treatment area were significantly lower during the 6 year period than those recorded in three non-treated areas. The strategy of combining suppression techniques in an area-wide approach is discussed

Les caracteres ecclesiastiques dans I'oeuvre d'Anatole France.

Le but de cette étude est de déterminer 1'attitude d'Anatole France envers l'Eglise, et particulièrement ses idées sur les prêtres catholiques. A cette fin, J'ai divisé ce traité en deux parties principales. La première partie traite des sources possibles, qui, selon mon Jugement, ont pu contribuer à influencer l'auteur dans la formation de ces idées religieuses, et ainsi dans ses opinions des prêtres de la religion catholique. En d'autres tenues, nous allons d'abord étudier ces choses qui le conduirent à rejeter le culte de ses ancêtres. [...

The Devil\u27s Territory The Modern World in Flannery O\u27Connor

Flannery O\u27Connor writes from the standpoint of Christian orthodoxy. That is the most sigificant point to consider in any study of her work. Her themes, here imagery, her grostequerie, her comedy -- all must be interpreted in the light of her Christian concerns. In particular, appearing over and over in her work in modern man searching for salvation in the false idols of the twentieth-century -- the city, modern technology, and secular philosphy and science. These idols invariably fail, leaving him ready for salvation through Christ. Along the way O\u27Connor employs images that effectively reveal the tawdriness, the emptiness, the artificiality, the desperation of modern life without the true salvation of Christ. Her modern searchers are memorable -- Haze Motes, Rayber and Tarwater, Tom T. Shiflett, Mr. Fortune, Ruby Hill, Mr. Head. And the images are unforgettable -- an artificial gold corsage, gaudy movie theaters, rhinestone-covered spectacles, sweet potato colored hair, the Walgreen drugstore. These images pervade O\u27Connor\u27s work and illuminate the modern world -- the devil\u27s territory. This paper will offer an interpretation of her work by examining her use of the imagery of the modern city and its accounterments. An introduction will briefly discuss the major critical approaches to O\u27Connor and their relationship to this thesis. The first chapter deals with A Good Man Is Hard to Find, the second with Everything That Rises Must Converge, and the third with The Violent Bear It Away. The last chapter will consider in detail Wise Blood, in which the use of imagery of the modern world appears most clearly, most pervasively, and most effectively

Cattle Grazing Effects on Macroinvertebrates in an Oregon Mountain Stream

Cattle grazing effects on aquatic macroinvertebrates were assessed in a 4-year experiment of a mountain stream in northeastern Oregon. From 1996 through 1999, 10 cow-calf pairs were introduced into 6 experimental units along the stream for 42 days between July and September, and effects on aquatic macroinvertebrates were compared with 3 units in which no grazing occurred. Streambank and geomorphological variables were also measured to provide context for interpretation of effects on aquatic macroinvertebrates. Macroinvertebrate response to grazing was subtle, indicated by significantly lower abundance in grazed units. We measured more profound effects on streambanks: grazing caused an average decrease of 18% in bank length of the highest stability/cover class and caused an average increase of 8% in the lowest condition class over the course of each summer. By June of each following year, banks had recovered to their previous June condition, but grazing each summer caused a progressively larger decline in bank condition by September. Streambank effects were accompanied by an increase in cobble embeddedness over time in grazed units and were correlated with grazing-associated stream widening. Treatment effects were overwhelmed, however, by a profound decline in the abundance of most macroinvertebrates over the study period, with a drop in September 1999 to 14% of the initial September abundance of 1997. While the drop was more precipitous in grazed units, declines were common to all study units, suggesting that something more widespread affected the system during this time. Logging on lands just upstream of the study area in 1998 and 1999, in which trucks drove through the study stream without the benefit of a culvert, sent sediment plumes into the study area each of those 2 years and could have caused the precipitous decline in aquatic macroinvertebrates. The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Survival of sterile male Mediterranean fruit flies in large field cages after release at different ages.

In Mediterranean fruit fly (Ceratitis capitata) sterile insect technique (SIT) programs worldwide, sterile flies are usually released at 2?3 days of age. However, they usually do not reach full sexual maturity until ca. 5 days of age. We tested whether holding sterile males longer at a fly emergence and release facility, until they were 5 days old, might result in significantly more flies surviving to reach sexual maturity in the field. In large field cages in Hawaii, we released sterile Mediterranean fruit fly males 2 or 5 days old under conditions where food and water were provided, or not provided. Flies were released 2 days after peak emergence in one field cage, while they were released 5 days after peak emergence in a second field cage. The numbers of flies flying out and remaining (dead, dying or non-flying) in the holding boxes were recorded on the day of fly release. At 5 and 8 days of fly age, the size of the male fly populations were estimated using trimedlure-baited traps placed into each of the two field cages for a 30-min period when the numbers of flies trapped were compared. Following six tests (three replications each with and without water and sugar provided), the differences in fly captures (i.e. survival) between 2 days vs. 5 days old releases were highly significant. With food and water provided, several times as many flies from the 5-day-old release field cage were captured at 5 and 8 days of age compared to the 2-day-old release field cage. These differences were magnified under conditions of no food and water provided. Holding Mediterranean fruit flies longer prior to release, requires more holding space and food, but will lead to significantly greater numbers of sexually mature flies in the field.Supplement 1
