8241 | 2014 article | Primary school pupils acquisition of science process skills via hands-on activities and authentic assessment Nik Yusuff Nik Azmah, Rahaman Nor Mahaiza, Abdullah Norazilawati, This study is about the acquisition of science process skills by primary school pupils by means of hands-on teaching and learning, and authentic assessment method. Their interest and motivation in science were also inquired. The participants for the 5 months study consisted of 24 year-five pupils in one primary school in Selangor, Malaysia. The instruments used were an observation checklist, sets of science process skills achievement test, and interviews. Data collected from observation and achievement tests were analysed using rubrics, while information from interviews are analysed using NVivo 2.0. Findings from this study showed that the acquisition of science process skills among the pupils has increased tremendously and their interest and motivation in science were high. They were also able to apply the knowledge gained from hands-on learning to solve authentic problems. Therefore it is suggested that hands-on science teaching and learning as well as authentic assessment are used i..... 955 hits |
8242 | 2014 article | Preventing flute playing-related musculoskeletal disorders: applying ergonomic principles in individual and ensemble settings Lonsdale Karen Anne, Concerning levels of playing-related musculoskeletal disorders (PRMD) among flute players have been reported over a number of decades. However, recent research indicates that many flute players do not receive sufficient training in injury prevention during their studies. Identifying risks and preventing injuries is central to occupational, health and safety, yet there is little emphasis on this topic in instructional flute books and methods. Improving the ergonomic set-up of musicians is one way of minimising the risk of playing-related injuries occurring. This article recommends six injury prevention strategies based on ergonomic principles that flute teachers and band directors can apply in individual and ensemble teaching settings... 553 hits |

8245 | 2009 article | Phase-controlled converter for Nd:YAG laser flashlamp driver Hadi Yaacob Mohd Ikhwan, Bidin Noriah, Mat Daud Yaacob, Phase-controlled technique through thyristors (SCR) is used instead of diodes in order to form a power converter. Output voltage of this power converter can be varied by controlling the firing angle of SCR and is used to charge the capacitor banks. Each firing angles are referred to zero-crossing point of each half of the 50 Hz AC voltage. Adjustable voltage is then used to charge the capacitor bank inside Capacitor Charging Power Supply (CCPS) for Xenon flashlamp driver. Flashlamp produced source of pulsed light that pumped the Nd:YAG laser crystal. The Nd:YAG laser usually operates at various input energies, thus requiring variable values of voltage to charge the capacitor bank. Developed phase-controlled converter can steadily controll the output voltage of CCPS from 500 V to 1000 V... 1104 hits |
8246 | 2014 article | Phytochemical study of stem bark from Alstonia spathulata Bl. (Apocynaceae) Tee Chuan Thing, Lee Yean Shan, Tan Siow Ping, Awang Khalijah, Nafiah Mohd Azlan, Ahmad Kartini, In Malaysia, Alstonia spathulata Bl. is locally known as ‘Pulai Basong’ which distribute in peat forest. The separation of the chemical components from hexane and DCM crude extract of Alstonia spathulata was carried out using column chromatography (CC) and thin layer chromatography (TCL) techniques. A total of five known compound were isolated from the stem bark extracts and identified as: β-amyrin, β-amyrin acetate, lupeol acetate, stigmasterol and β-sitosterol. The elucidation structures of these compounds were established using 1D-NMR (1H, 13C and DEPT) and 2D-NMR (COSY, HSQC, HMBC) spectroscopic analysis, involving also comparison with data from the literature... 2346 hits |

8248 | 2015 article | Preliminary toxicity test and phytochemical screening of Sargassum polycystum crude extracts from marine macroalgae Daud Norhayati, Mohd Noor Nor Nafizah, Alimon Hasimah, Abdul Rashid Nursuhaidah, Sargassum polycystum is a species of brown algae (Phaeophyta). Some recent studies have found many uses of this algae, one of them is for medicine. In this study, crude hexane, dichloromethane and methanol extracts of Sargassum polycystum were tested for toxicity activity and screened for its principal chemical substances. The toxicity test was done using Brine Shrimp Lethality (BSL) test against Artemia salina Leach. The results of this study showed the LC50 value of methanol extract was 295.12 mgml-1, while both hexane and dichloromethane extracts were 275.42 mgml-1. The BSL test exhibited no significant toxicity against A.salina. Phytochemical screening shows S. polycystum contained non polar and polar components. As the conclusion, S. polycystum contained secondary metabolites that are not toxic to A. salina and they are not a potential source for toxicity... 2303 hits |
