Physical profiling of international cricket players: an investigation between bowlers and batters
Get PDFThis study aimed to develop a physical profile of international cricketers, and investigate if positional differences exist between bowlers and batters. Nineteen, international male cricketers, eleven bowlers (age 24.1 ± 5.2 years; height 179.73 ± 5.27 cm; weight 73.64 ± 6.65 kg), and eight batters (age 22.9 ± 3.8 years; height 180.25 ± 5.57 cm; weight 77.01 ± 8.99 kg) participated in this study. The physical test battery included; power, speed, strength and aerobic fitness tests. Batters demonstrated significantly higher scores for the countermovement jump (p \u3c 0.03; ES = -1.55) and squat jump (p \u3c 0.03; ES = -0.98). Furthermore, batters showed non-significant but small ES for faster 0–5 m (ES = 0.40) and 0–10 m (ES = 0.35) sprint times, superior hand grip strength (ES = -0.20), and higher Yo-Yo intermittent recovery test scores (ES = -0.46). Bowlers showed non-significant but small ES for faster 5 km time trials (ES = -0.51), lower bodyweight (ES = -0.42) and lower body fat percentage (ES = -0.30). However, intra-positional (i.e., seam and spin bowlers) and individual differences amongst players were observed. The physical profiles presented in this study can be used by coaches responsible for the physical development of cricket players to compare their existing data with. Furthermore, it is recommended that practitioners account for individual physical fitness profiles in addition to team profiles, to effectively design and evaluate tailored programs, with the aim of improving both physical and cricket performance
Allometry of urban trees in subtropical Hong Kong and effects of habitat types
No full text© 2020, Springer Nature B.V. Context: Quantitative information regarding tree species-specific size is an essential tool for landscape planning. It reflects tree-environment and human–environment interactions in the urban landscape. The effects of habitat types on tree allometry have seldom been evaluated. Objectives: Firstly, to derive size-related information of common urban tree species in Hong Kong. Secondly, to evaluate the effects of habitat types on tree allometry. Methods: A database of 28,622 trees was established by a field assessment. The allometric relationships (DBH-height and DBH-crown width relationships), by both OLS regression and quantile regression, and maximum size of 30 common urban tree species, and the effects of five main habitat types on tree allometry were determined. Species were assigned to groups according to dimensional traits by cluster analysis. Results: In general, the allometric relationships of height and crown width to DBH were significant and varied among species. The wide prediction intervals of the OLS regression indicated the high uncertainty of allometric relationships in our region. The 99th percentile crown width of most species reached 10 m, hinting the general failure of most habitats to meet the planting space requirement. Only two large-stature species have narrow crowns. Habitat types posed significant but small species-specific effects on tree allometry. Roadside tree pit was a particularly stressful environment. Conclusions: Our findings can act as a reference for landscape planning and management in Hong Kong and nearby cities, including species growth space requirement and habitat limitations. However, prediction of height or crown width from DBH must be carefully interpreted in our city
Thermal-irradiance behaviours of subtropical intensive green roof in winter and landscape-soil design implications
No full text© 2019 Elsevier B.V. As urban green space, green roof has been increasingly installed in cities mainly for amenities, temperature regulation and energy conservation. Nevertheless, in subtropical urban setting and during winter, the thermal and radiation behaviours of green roofs, especially the intensive type, have remained poorly understood. This paper examined the effect of a woodland-type intensive green roof (IGR) on the roof-level microclimate by comparing temperature and radiation parameters against a reference bare roof (BR). In-situ microclimatic monitoring was conducted on an IGR and BR pair in subtropical Hong Kong throughout a winter. Using objective selection criteria, 30 sampled days with representative winter weather, namely sunny, cloudy and rainy conditions, were identified for statistical analyses of interactions among key factors. The results showed that the woodland canopy intercepted about 90% of incoming solar radiation regardless of weather, thus substantially suppressing the energy source of passive warming, and instead creating undesirable cooling of ground surface and canopy-enclosed air. Surface and air temperatures on IGR were lower than BR, with the highest mean difference reaching 2.77 °C and 2.27 °C respectively in sunny daytime. The vegetation canopy retained some but insufficient outgoing thermal radiation to counteract the observed cooling. Limited solar inputs could only slightly warm the soil which experienced heat loss in cloudy weather to raise indoor heating load. The empirical findings provided the basis to recommend changes in landscape and soil designs to allow IGR to yield thermal benefits in winter and to improve building energy efficiency
An experimental study to measure the concentration of nanofluids by using refractive index
Get PDFIn a decade, nanofluids are a new kind of fluid that has rapid development and wide application in various fields. Especially, nanofluids as a heat transfer fluids in different industrial instead of the traditional heat transfer fluids such as water, oil, and ethylene glycol…etc. The nanofluids have consisted the nano-size metal or metal oxide pArticles with base fluids, the nanoparticles have a superior thermo property to enhance the heat transfer performance of based fluids. Concentration is an important factor that can be influenced by most of the thermal properties of nanofluids. In present, the concentration of nanofluids is predetermined, the amount of nanoparticle and the base fluids should be measured before the nanofluids preparation. However, no specific method for the measurement of nanofluids concentration in real-time and by non-contact method until the present. The Refractive index is an important parameter of material. It is also applied in much researches for material analysis such as material concentration analysis. The current study intended to experiment to find out the correlation between the refractive index and concentration of nanofluids for further development of the non-contact method for the measurement of nanofluids. In this study, a total of 10 different concentrations of Titania oxide (TiO2) nanofluid samples prepared for measurement of refractive index by the minimum deviation method and reference to Jenkin\u27s proposed experiment setting in 1982. The results of this study presented that the refractive index value increased from 1.3411 to 1.3953 by increasing the TiO2 nanofluid concentration from 0.001% to 0.04%. The results of this works will be very helpful for further development of the method of measurement of the nanofluids concentration
