Enhanced Performance Of Dye Sensitized Solar Cells Utilizing Platinum Electrodeposit Counter Electrodes, Attila J. Mozer, George Tsekouras, Gordon G. Wallace
Enhanced Performance Of Dye Sensitized Solar Cells Utilizing Platinum Electrodeposit Counter Electrodes, Attila J. Mozer, George Tsekouras, Gordon G. Wallace
Gordon Wallace
Enhanced performance was observed for dye-sensitized solar cells (DSSCs) utilizing counter electrodes based on Pt electrodeposits compared to counter electrodes based on sputtered Pt. Scanning electron microscopy of Pt electrodeposits revealed that the use of an initial cathodic overpotential pulse followed by steady electrodeposition at a mild cathodic potential yielded ∼40nm particles, compared to ∼600nm particles when no such pulse was used. Cyclic voltammetry and electrochemical impedance spectroscopy (EIS) of electrode materials suggested that Pt electrodeposits would give enhanced performance as DSSC counter electrodes compared to sputtered Pt, and this was confirmed by device testing. EIS characterization of DSSCs under …
Age-Related Changes In Conventional Road Versus Off-Road Triathlon Performance, Romuald Lepers, Paul Stapley
Age-Related Changes In Conventional Road Versus Off-Road Triathlon Performance, Romuald Lepers, Paul Stapley
Dr Paul J Stapley
The aims of this study were: (i) to analyze agerelated declines in swimming, cycling, and running performances for road-based and off-road triathlons, and (ii) to compare age-related changes in these three disciplines between road-based and off-road triathlons. Swimming, cycling, running and total time performances of the top five males between 20 and 70 years of age (in 5-year intervals) were analyzed for short distance road-based (1.5 km swim, 40 km cycle, and 10 km run) and off-road (1.5 km swim, 30 km mountain bike, and 11 km trail run) triathlons at the 2009 World Championships. Independently of age, there was …
Differences In Gender And Performance In Off-Road Triathlon, Romuald Lepers, Paul Stapley
Differences In Gender And Performance In Off-Road Triathlon, Romuald Lepers, Paul Stapley
Dr Paul J Stapley
The aims of this study were: (1) to examine performance trends and compare elite male and female athletes at the off-road triathlon (1.5-km swim, 30-km mountain biking, and 11-km trail running) world championships since its inception in 1996, and (2) to compare gender-related differences between off-road triathlon and conventional road-based triathlon. Linear regression analyses and ANOVA were used to examine performance trends and differences between the sexes. Elite male performance times stabilized over the 2005-2009 period, whereas elite female performance times continued to improve, especially for the run leg. Differences in performance times between the sexes were less marked in …
Performance Of Body Mass Index In Predicting Diabetes And Hypertension In The Eastern Province Of Saudi Arabia, Ali M. Almajwal, Nadira A. Al-Baghli, Marijka J. Batterham, Peter G. Williams, Khalid A. Al-Turki, Aqeel J. Al-Ghamdi
Performance Of Body Mass Index In Predicting Diabetes And Hypertension In The Eastern Province Of Saudi Arabia, Ali M. Almajwal, Nadira A. Al-Baghli, Marijka J. Batterham, Peter G. Williams, Khalid A. Al-Turki, Aqeel J. Al-Ghamdi
Dr Marijka Batterham
BACKGROUND AND OBJECTIVES: BMI is the most widely used measure to diagnose obesity but its accuracy and usefulness in Saudi subjects is unknown. This study aimed to assess the validity of standard BMI cut-point values in the Saudi population. SUBJECTS/ METHODS: 197,681 adults participated in a cross-sectional study to detect diabetes and hypertension in the Saudi Eastern province in 2004/5, with blood pressure, fasting blood sugar, height and weight measurements taken. Sensitivities, specificities, areas under the curves, predictive values, likelihood ratios, false positive, false negatives and total misclassification ratios were calculated for various BMI values determined from receiver operating characteristic …
The Relationship Between Driving Anxiety And Driving Skill: A Review Of Human Factors And Anxiety-Performance Theories To Clarify Future Research Needs, Joanne Taylor, Frank P. Deane, John Podd
The Relationship Between Driving Anxiety And Driving Skill: A Review Of Human Factors And Anxiety-Performance Theories To Clarify Future Research Needs, Joanne Taylor, Frank P. Deane, John Podd
Frank Deane
This article examines theory and identifies gaps in research related to the role of driving skills in driving anxiety. Increasingly, investigators have examined the clinical features of driving anxiety and the more severe situation of driving fear and phobia, but the possible involvement of driving skills has been neglected. This is surprising given the potential implications for skills training and remediation in the assessment and treatment of some of those who experience driving anxiety, fear, and phobia. The largest body of relevant research comes from the driving and human factors literature on the relationship between anxiety and driving performance. The …

Examining The Direction Of Imagery And Self-Talk On Dart-Throwing Performance And Self Efficacy, Jennifer Cumming, Sanna M. Nordin, Robin Horton, Scott Reynolds
Jennifer Cumming
The study investigated the impact of varying combinations of facilitative and debilitative imagery and self-talk (ST) on self-effi cacy and performance of a dart-throwing task. Participants (N = 95) were allocated to 1 of 5 groups: (a) facilitative imagery/facilitative ST, (b) facilitative imagery/debilitative ST, (c) debilitative imagery/facilitative ST, (d) debilitative imagery/debilitative ST, or (e) control. Mixed-design ANOVAs revealed that performance, but not self-effi - cacy, changed over time as a function of the assigned experimental condition. Participants in the debilitative imagery/debilitative ST condition worsened their performance, and participants in the facilitative imagery/facilitative ST condition achieved better scores. These fi ndings …
