Effects of Triclopyr on Variable-Leaf Watermilfoil

The objective of the study described here was to determine the effect on variable-leaf watermilfoil of various combinations of triclopyr concentrations and exposure times using dosage rates that controlled Eurasian watermilfoil under laboratory and field conditions (Netherland and Getsinger 1992, Getsinger et al. 1997, Petty et al. 1998)

Psychological Readiness Effect on Return-to-Play in Collegiate Athletes

Psychological readiness has been studied extensively over the past 20 years.2,4,6 It is becoming increasingly important to understand completely how athletes psychologically deal with a physical injury. Current research has identified specific intrinsic and extrinsic factors that have shown to present negative effects on athletes.1,4,5 They have also identified specific psychological factors that play a major role in the rehabilitation process.2,3,5 However, current research has not studied the entire psychological experience of athletes and their determining factors. They also have not used surveys that allow for both qualitative and quantitative data to be collected. Therefore, the purpose of this study was to see what psychological extrinsic and intrinsic factors combined, do to the return to play of collegiate athletes. To identify the correlation between psychological readiness and return to play, surveys were distributed to NCAA universities within the state of Ohio. Athletic trainers then distributed the survey to all athletes who had missed sport related activities due to their injury. Quantitative results showed no statistical difference, but there were common themes found within the qualitative data. The qualitative results showed similar results to current research. Results showed that athletes tend to do more than what their athletic trainers allowed them, coaches pressured athletes to return sooner than they could, and overall athletes had a good rehabilitation experience. Despite the amount of limitations in this study, the qualitative data will help further athletic trainers knowledge about how athletes react to athletic injuries

Gas temperature measurements using the dual-line detection Rayleigh scattering technique

A new laser-induced Rayleigh scattering method is presented for the improved temperature diagnostics of gas flows. In the present technique, the two lines of a copper vapor laser are used to obtain the time and space resolved temperature. A single set of optics is used to form the optical probe and to collect the signal simultaneously from both the 510 nm and the 578 nm lines. The dual-line detection allows for the determination and removal of surface-scattered laser light from a Rayleigh signal thereby improving the applicability of Rayleigh scattering to near wall flows with a high degree of glare. An optical system using the dual-line detection technique is built, calibrated and tested in a hot air jet under various levels of background contamination. The results indicate that highly accurate temperature measurements are possible even when the laser-line background intensity, captured by the collecting optics, is five times that of the Rayleigh signal

Experiential aspects of neglect: a phenomenological inquiry

A review of the empirical literature on maltreatment points to the need for more knowledge about neglect, especially the subjective aspects of neglect. In order to gain information about this topic, twelve adult volunteers were interviewed in detail about various times in which they had experienced themselves as neglected. In accordance with the principles of existential phenomenology, a qualitative methodology for research within the social sciences, the transcribed interviews were thematized, in this case with the aid of a group of scholars trained in phenomenological interpretation. Three interrelated themes emerged against the ground of Interpersonal Relationships: Feeling Alone, Feeling Invisible And Being Used. A fourth related theme. Being Affected, emerged against the ground ofThe Self. Implications for conducting psychotherapy with those who have experienced themselves as neglected are addressed, as are suggestions for future research
