Electromyographic Analysis of Trunk Musculature following a Nine Hole Round of Golf: The Fatigue Factor
No full textThe purpose of this study is to determine the fatigue component in trunk musculature following a simulated nine hole round of golf through analysis of the trunk muscles during the golf swing.
Our subjects consisted of 4 males ages 22-26. Each subject performed 5 EMG monitored golf swings with a driver prior to and following a simulated 9 hole round of golf. This provided pre-round and post-round data to analyze and determine if significant fatigue occurred in the trunk musculature.
The results showed that a significant shift in median frequency occurred, signifying muscle fatigue, in 2 of the 4 subjects when all muscles were analyzed collectively. When individual muscles were analyzed each muscle experienced a significant shift in median frequency except the left abdominal oblique. The swing times for each subject were also analyzed and compared. The 2 subjects who fatigued demonstrated faster swing times suggesting a possible relationship between speed of the golf swing in increased muscle force output and increased muscle fatigue. These results will attempt to provide information on establishing training and conditioning programs targeting the trunk musculature. These programs can be developed to increase muscle endurance and decrease the likelihood of faulty swing mechanics and injury

Breaking News : Geneviève Thauvette
No full text" On view on the Inc.’s external Cannon Project Wall, Breaking News consists of a series of hand tinted self-portrait photographs that satirize the format and content of news reports. Through parody and caricature, heavy subject matter such as abduction, flood, disaster, televised suicide, and dictatorship are depicted in a surreal and jocular newsroom simulation. While the images are bright and enticing, the installation demands serious contemplation of how individuals in power and mainstream media work hand-in-hand to undermine the integrity and veracity of current events.

Test results and conditioning procedure of a limited streamer-tube calorimeter
No full textThe CHARM II Collaboration has built a massive, fine-grained calorimeter for the study of the elastic scattering {A figure is presented} short description of the detector will be followed by the presentation of some results obtained by exposing 40 of the 441 planes of the calorimeter to a beam of electrons and pions. Comments will be given about the conditioning procedure followed for the 154560 limited streamer tubes which compose the active part of the calorimeter
Thermal Properties of the Silicon Microstrip Endcap Detector
No full textIrradiated silicon detectors must be cooled in order to guarantee stable short and long term operation. Using the SiF1 milestone prototype we have performed a detailed analysis of the thermal properties of the silicon microstrip endcap detector. The strongest constraint on the cooling system is shown to be set by the need to avoid thermal runaway of the silicon detectors. We show that, taking into account the radiation damage to the silicon after 10 years of LHC operation and including some safety margin, the detector will need a cooling fluid temperature of around -20 C. The highest temperature on the silicon will then be in the range -15 C to -10 C. This sets an upper limit on the ambient temperature in the tracker volume

Test results of the streamer-tube system of the CHARM II neutrino detector
No full textThe CHARM II Collaboration is building a massive, fine-grained and low-density detector for the study of neutrino-electron scattering. Its target calorimeter consists of 441 detector planes with 155 232 plastic streamer tubes with digital readout of the wires and analog readout of external pickup strips. At the time of this report, about 25% of the calorimeter planes were equipped with electronics. Results on the performance of these tubes are presented as obtained with cosmic-rays and with electron and pion beams. We have also investigated the use of water vapour as an additive to the gas to suppress coating of the anode wires. The use of water would be of particular importance when using the tubes in a high-rate environment
