Utilization of BLOSSOMS Thermodynamics Energy Conversion video to properly incorporate active learning techniques had been shown to increase the students’ performance in learning introductory Thermodynamics topics. In this study, the effectiveness of using BLOSSOMS Thermodynamics Energy Conver-sion video towards students’ learning in a classroom when adopted by lecturers who is not trained in active learning is investigated. Two groups of undergraduate engineering students from a control class and a treatment class were involved in this study. The students from the treatment class were taught by a lecturer using the BLOSSOMS Thermodynamics Energy Conversion video, while the students from control class underwent conventional lecture style. The students were given pre and post inventory tests and their results were analysed using SPSS. It was found that BLOSSOMS Thermodynamics Energy Conversion video without the proper implementation of active learning technique does not have a significant ef-fect on the individual learning gain of the inventory test among students. The uti-lization of the video could be more effective if the instructor is well-trained in ac-tive learning techniques.

Construction waste is generated throughout the construction process such as during site clearance, material use, material damage, material non-use, excess procurement and human error. The exact quantity and composition of construction waste generated throughout the projects are difficult to be identified as they are keep on changing due to the dynamic nature of the construction activities. Different stages of construction generates different types and composition of waste. Therefore the trend of waste generated throughout the construction stages need to be identified. This paper will critically review literature on construction waste in order to understand the nature of waste generation from construction activities. Based on the literature studied, this paper propose a method to quantify waste for conventional construction. The proposed method comprises four steps. First is identification of construction stages and expected waste generated. Second is selection of construction sites with similar characteristics for uniform investigation. Third is sorting and weighing of mixed waste collected in a dumpster. The last step is summation of the recorded quantity. It is expected that the proposed method should be practical and suits current situation of Malaysian construction projects and support the agenda of National Strategic Plan for Solid Waste Management.

Surface discharge is a common electrical discharge that normally occurs on the surface of outdoor insulators and also causes the failure in the electrical insulation system. One of the causes of surface discharge is the presence of high voltage stress. Experimental works had been carried out to examine the surface discharge characteristics on polymeric samples as insulation material. The IEC (b) electrode configuration had been used to investigate the surface discharges phenomena of different types of polymeric materials with controlled of air relative humidity (RH). In these experimental works, three types of polymeric sample were selected, namely high-density polyethylene (HDPE), ethylene-vinyl acetate (EVA), and polystyrene (PS), respectively. The characteristics of the discharge are critically depending on the types of polymer. Surface discharges intensity, number of discharge occurrence, and surface morphology of each polymeric material were also investigated. Comparisons of these electrical characteristics were conducted among the samples. Results from the experiment showed that the EVA samples experienced severe degradation as compared to HDPE and PS samples.
