The effect of caffeine ingestion on mood state and bench press performance to failure.

Abstract: Research has suggested that caffeine enhances aerobic performance. The evidence for high-intensity, short-term exercise, particularly resistance exercise is mixed and has not fully examined the psychological changes that occur after this mode of exercise with caffeine ingestion. This study examined the effect of caffeine (5 mg · kg(-1)) vs. placebo on bench press exercise to failure and the mood state response pre to postexercise. Thirteen moderately trained men (22.7 ± 6.0 years) completed 2 laboratory visits, after determination of 1 repetition maximum (1RM) on the bench press, where they performed bench press repetitions to failure at a load of 60% 1RM. Mood state was assessed 60 minutes pre and immediately post-substance ingestion. Borg's rating of perceived exertion (RPE) and peak blood lactate (PBla) were assessed after each test, and peak heart rate (PHR) was determined using heart rate telemetry. Participants completed significantly more repetitions to failure (p = 0.031) and lifted significantly greater weight (p = 0.027) in the caffeine condition compared to the placebo condition. The PHR (p = 0.0001) and PBla (p = 0.002) were higher after caffeine ingestion. The RPE was not different across conditions (p = 0.082). Mood state scores for vigor were greater (p = 0.001) and fatigue scores lower (p = 0.04) in the presence of caffeine. Fatigue scores were greater postexercise (p = 0.001) compared to scores pre exercise across conditions. Caffeine ingestion enhances performance in short-term, resistance exercise to failure and may favorably change the mood state response to exercise compared to a placebo.

The convergence of gaming practices with other media forms: what potential for learning? A review of the literature

Abstract: Nowhere in the current digital technology landscape is the process of ‘blurring the lines between media’ more apparent than with the uses and applications of gaming practices and technologies. Here the overlaps between new media and media interfaces are becoming significant as games technologies and practices are becoming more pervasive as commonplace social practices. This article reviews literature for evidence of these trends of convergent media forms as a starting point for a wider debate for using games technologies and practices to support learning practices. The article outlines convergences between gaming and cinema, gaming and the Internet, and gaming and emergent technologies and interfaces (e.g. mobile phones and social software). The article aims to foreground major dimensions of convergence in relation to the potential of innovations in educational practice and activities. The article concludes that variant forms of gaming are widespread. But while the converging forms of gaming with other me...

Removal of captopril pharmaceutical from synthetic pharmaceutical-industry wastewaters: Use of activated carbon derived from Butia catarinensis

Abstract: A high surface area activated carbon was produced from the seed of Butia catarinensis (Bc), which was utilized for removing captopril from synthetic pharmaceutical industry wastewaters. The activated carbon was made by mixing ZnCl2 and Bc at a proportion of 1:1 and pyrolyzed at 600° (ABc-600). The material was characterized by the Boehm titration, hydrophilic/ hydrophobic ratio, elemental analysis, TGA, FTIR, and N2 isotherm (surface area (SBET), total pore volume (TPV), and pore size distribution (PSD)). The characterization data showed that the adsorbent displayed a hydrophilic surface due to the presence of several polar groups. The carbon material presented a TPV of 0.392 cm3 g−1, and SBET of 1267 m2 g−1. The equilibrium and kinetics data were suitably fitted to Liu isotherm and Avrami-fractional-order. The employment of the ABc-600 in the treatment of synthetic pharmaceutical industry wastewater exhibited high effectiveness in their removals (up to 99.0 %).

Metrical Stress Sensitivity in Young Children and Its Relationship to Phonological Awareness and Reading.

Abstract: This paper reports two studies of young English-speaking children's ability to cope with changes to the metrical stress pattern of spoken words and the relationship between this ability, phonological awareness and early reading development. Initially, 39 children aged 4 and 5 years were assessed on their ability to identify mispronounced words, including words that had their metrical stress pattern reversed. The children were significantly worse at identifying words that had their metrical stress pattern reversed than words that were mispronounced in other ways. The second study was a cross-sectional comparison of 31 5, 6 and 7-year-old children's performance on the metrical stress reversal condition of the mispronunciation task. Measures of the children's written language skills and phonological awareness were also taken. The 7-year-old children outperformed the 5-year-olds on the metrical stress task. Performance on this measure was associated with most of the measures of phonological awareness and literacy, and was associated with rhyme awareness and spelling ability after age had been taken into account. Moreover, metrical stress sensitivity could account for variance in spelling ability after phonological awareness had been taken into account, and after vocabulary had been taken into account. This suggests that stress sensitivity may influence spelling development in a way that is independent of its contribution to phonological representations.

Synthesis and DFT investigation of new bismuth-containing MAX phases.

Abstract: The Mn + 1AXn phases (M = early transition metal; A = group A element and X = C and N) are materials exhibiting many important metallic and ceramic properties. In the present study powder processing experiments and density functional theory calculations are employed in parallel to examine formation of Zr2(Al1-xBix)C (0 ≤ x ≤ 1). Here we show that Zr2(Al1-xBix)C, and particularly with x ≈ 0.58, can be formed from powders even though the end members Zr2BiC and Zr2AlC seemingly cannot. This represents a significant extension of the MAX phase family, as this is the first report of a bismuth-based MAX phase.
