How perceiving additional baskets modifies youth basketball players’ performances
No full textThis study aimed to identify how playing basketball with two additional baskets influences the players’ technical, physiological, physical and especially, positional performance. Fourteen youth players performed eight 5vs.5 simulated basketball games, four with the two official baskets and four with two-extra official baskets, each one placed in the court restricted area. The variables collected were technical (field-goals made and missed, offensive and defensive rebounds, steals, passes, dribble-drive, give-and-go and ball possessions), physiological (heart rate monotony and sample entropy), workload (total distance covered and distance covered at different velocities) and positioning-related (distance to the nearest opponent, distance to the nearest teammate, stretch-index and distance between centroids). The results showed that the four-baskets games favoured the emergence of individual behaviours, increasing the game\u27 physical demands and promoting a collective dispersion, which might impair team playing. Conversely, when playing with two-baskets, there was less distance between teammates. In conclusion, this study has clear implications for practice as it emphasizes that coaches can manipulate the number of baskets to modulate training workload and promote different individual and team behaviours
《香港最早期政黨及民主鬥士：革新會及公民協會》
No full text一直以來，香港史的論著都認為本地政黨在上世紀八十年代後才興起，而香港人在九十年代開始才比較關心政治。本書通過對戰後初期成立的香港革新會及香港公民協會的詳細研究，推翻上述看法。香港革新會及香港公民協會並非一般所指的壓力團體，而是積極爭取政治、經濟及社會改革的政黨。作為政府與市民之間的橋樑，它們特別關注香港的城市發展、房屋政策、醫療保障、經濟發展、教育普及、治安及小販問題。兩個政黨的活躍成員包括貝納祺、簡悅強、葉錫恩、胡鴻烈、張有興、鄒偉雄、陳子鈞等，擔任市政局議員多年，在當年香港社會和政壇甚有影響力。本書首開這兩個政黨學術研究之先河，通過本研究，可加深對殖民政府與宗主國的關係、戰後的殖民地性質，以及被遺忘的香港革新會及香港公民協會的了解
Color Reflectance Study of Decolorized Reactive Dyed Cotton Knitted Fabric by Ozone Plasma Treatment
No full textOzone plasma treatment is available to be applied on color modification and color fading due to ozone generating function. It is an environment friendly process that treats died cotton under dry condition in order to avoid chemical effluents. This study aims to investigate color reflectance of decolorized reactive dyed cotton knitted fabric by ozone plasma treatment. Reactive dyed cotton knitted fabrics with different color depths (0.5%, 1.5%, 3.0%) were prepared to be treated by various of plasma conditions, including different ozone concentrations (10%, 30%, 50%, 70%) controlled by adjusting gas power output, water contents (35%, 45%) of fabric samples and ozone treatment durations (10 mins, 20 mins, 30 mins). The color fading effect is evaluated by the color reflectance percentage (R%) using spectrophotometer under illuminant D65. The effective decolorization in terms of high reflectance percentage was revealed from plasma treatment with higher ozone concentrations (50% and 70% ozone in air) and longer treatment duration (20 mins or above). However, the percentage of water content contained in the fabrics is shown to have insignificant relationship with the color fading effects
Atmospheric pressure plasma‐induced decolorisation of cotton knitted fabric dyed with reactive dye
No full textThe aim of this study was to investigate the decolorisation effect of atmospheric pressure plasma treatment on knitted fabrics dyed with reactive dyes under different processing parameters, ie, air concentration, treatment duration and water content. The fabrics were dyed with reactive dye of a blue colour, and the colour depths were 0.5%, 1.5% and 3.0% on weight of fabric. The colour properties of untreated and plasma‐treated fabric samples were evaluated by means of reflectance, K/S and relative unlevelness index. The colour properties were evaluated instrumentally and quantitatively in order to study the decolorisation effect induced by atmospheric pressure plasma treatment. Experimental results revealed that the desired decolorisation effect was heavily influenced by the atmospheric pressure plasma treatment processing parameters. Although the desired decolorisation effect could be obtained by controlling the processing parameters of the atmospheric pressure plasma treatment, the treatment did not provide any significant reduction in the bursting strength of the fabric
NiMoAl catalysts derived from heptamolybdate-intercalated layered double hydroxides for hydrodeoxygenation of Anisole
No full textThe catalytic performance of NiMoAl catalysts derived from layered double hydroxide (LDH) precursors with molybdenum species incorporated into the interlayers was investigated for the hydrodeoxygenation (HDO) of anisole as a model compound of the lignin. The results showed that high dispersion of small Ni nanoparticles with 2–5 nm due to the pinning effect of Mo from Mo7O246− intercalated the LDHs. Due to presence of the oxygen vacancy sites on the molybdenum oxide, the NiMoAl catalysts exhibit higher conversion of anisole than the corresponding NiAl catalyst. The activity for hydrodeoxygenation was enhanced with the increased content of molybdenum species, which can be attributed to the larger amount of acid sites-promoted removal of oxygen from anisole. In addition, the NiMoAl catalysts show higher resistance to deactivation than the NiAl catalyst, and can be broadly applied to other hydrodeoxygenation reactions
Effects of eccentricity on seismic behavior of non-seismically designed reinforced concrete beam-column joint
No full textThe staggering numbers of eccentric reinforced concrete beam-column joints without seismic design details were used in existing RC frame building due to geometrical constraints, which implied high susceptibility of the building structures to anticipated seismic risk. Three exterior RC beam-column joints were fabricated and tested, which were applied reversed cyclic loads to simulate seismic action. In this study, the effects of stirrup ratio in joints and the eccentricity which is defined as the distance between the axis of the beam and column on seismic performance are investigated. The test results provide a further understanding of the failure mode and shear strength of exterior beam-column joints. It is shown that the eccentricity will significantly reduce the seismic performance and shear strength of the joints, which will cause the brittle failure of frame buildings, while the stirrups in the joint core can improve the seismic performance. To verify the availability of current codes in predicting the shear strength of eccentric beam-column joints with non-seismic detailed, the experimental results are compared with the predicted shear force of two non-seismic codes (HK code and Eurocode 2) and three seismic codes (Eurocode 8, NZS 3101 and ACI 318-14). The comparison results indicate that the existing non-seismic and seismic design codes of practice do not predict the shear strength of the exterior non-seismically designed joints precisely
