Improving biocompatibility of cobalt based alloy using chemical etching and mechanical treatment
Arman Shah bin Abdullah
Biomedical grade of cobalt based alloy have found a plethora of applications as medical devices especially in dental and articulation joints like in total ankle, knee and hip arthroplasty. However, the long-term performance of this material is highly dependent on their ability to withstand in harsh aqueous environment effects such as corrosion and wear once they are used inside a human body. Loss of surface integrity and subsequent leaching of toxic metal ions as well as particles to the surrounding tissues may undermine biocompatibility of metallic implants, also potentially causing untimely loss of mechanical function and device failure. In this study, a biomedical grade of CoCrMo alloy surface was treated with various surface modification techniques such as chemical etching and mechanical roughening in order to improve its biocompatibility. Investigation was done to study which surface modification techniques possesses the positive effect in cell growth and exhibit excellent cell re.....

Keberkesanan perisian permainan komputer fracblock dalam pembelajaran pecahan di sekolah rendah
Yusri Abdullah
This research has developed an educational computer based software named FracBlock to enhance learning the topic ?fraction? for year 4. This software is used as an enhancement activity and to help students to master the topic. FracBlock software is developed based on the Multimedia Development Alessi & Trollip Model. The design of this research is Quasi Pre & Post Trial method with a controlled group. The sampel for this research is sixty students from year 4, comprising thirty for the treatment group and another thirty for the controlled group. This research also determines the change in student‘s attitude towards computer and learning mathematics after using the FracBlock software and evaluating the software. The change in attitude is measured using questionnaire which was translated from the Yong Children’s Computer Inventory and childrens attitude towards learning mathematics is measured with also a questionnaire translated from the Fennema-Sherman Attitude Scales. The quality .....

Pengaruh gaya kepimpinan guru terhadap tahap kepuasan murid dalam pengajaran dan pembelajaran Pendidikan Jasmani sekolah menengah
Ruzeanna Abdullah@Jahari
Pendidikan Jasmani dan Kesihatan (PJK) sering dianggap sebagai mata pelajaran sampingan, tidak penting mahupun mata pelajaran main-main. Rasionalnya adalah kerana mata pelajaran ini tidak dinilai dalam peperiksaan-peperiksaan utama, mata pelajaran ini di pandang sambil lewa sehingga ada sekolah yang mengambil waktu mata pelajaran Pendidikan Jasmani untuk di gantikan dengan aktiviti pengajaran dan pembelajaran mata pelajaran lain yang lebih penting dan di ambil dalam peperiksaan utama...

Mai Shihah Abdullah
Epidemiological studies pensensitifan allergens allergic three groups consisting of food , inhalan and apiculture products was conducted among residents Tanjong Malim , Perak . A total of 2523 respondents , including 141 indigenous population ( 41.4 % male , 58.5 % female : 30.8 % of children , 69.2 % adults : 94.4 % of the population urban , rural 5.6% ) were interviewed and underwent skin prick test . A total of 633 complete data index of mother, father and siblings were used to Familial aggregation test model . Design ex post facto correlation using a questionnaire to obtain information from the self- reporting respondents . Questionnaires were divided into five groups with two ( familial and symptoms) represents a factor of atopic booster while three others ( settlements , style life and behavior ) represents an environment encouraging factors . Panel battery test containing 43 allergens ( 19 meals , 9 and 15 inhalan apiculture products ) used to test for allergic sensitivity respo.....

High energy density fuels derived from Mallee Biomass: fuel properties and implications
Hanisom Abdullah
Mallee Biomass is considered to be a second-generation renewable feedstock in Australia and will play an important role in bioenergy development in Australia. Its production is of large-scale, low cost, small carbon footprint and high energy efficiency. However, biomass as a direct fuel is widely dispersed, bulky, fibrous and of high moisture content and low energy density. High logistic cost, poor grindability and mismatch of fuel property with coal are some of the key issues that impede biomass utilisation for power generation. Therefore, innovations are in urgent need to improve biomass volumetric energy densification, grindability and good fuel matching if co-fired with coal. Biomass pyrolysis is a flexible and low-cost approach that can be deployed for this purpose. Via pyrolysis, the bulky biomass can be converted to biomass-derived high-energy-density fuels such as biochar and/or biooil. So far there has been a lack of fundamental understanding of mallee biomass pyrolysis and pr.....

Rhythmic transitions during game playing session: a case study of Malaysian gamers
Muhammad Fadhil Wong Abdullah
This research investigates the actions of gamers during the in-game cut-scenes transitions and how they adapt in multiple higher level actions during their game playing sessions. Drawing on Mediated Discourse Analysis and Multimodal Interaction Analysis, the exact lower-level action - pressing a button and higher-level action - playing a game provides important insights throughout the entire video game playing session obtained through video ethnography method. Video data of 5760 minutes were collected over a period of twelve weeks from four participants. Videos transcription and multimodal transcript were utilized to further explain the complex interaction between the video gamer and the video game playing. The term ‘Rhythmic Transitions’ was derived from this research which explains the switching over from the primarily focused attention away during cut-scenes provided us with a perfectly linked and synchronized rhythm of actions. Findings provide important insights to games’ de.....

Prior knowledge in reading and comprehension
Maria Shu Hong Bee Abdullah
This research investigates a group of primary five students utilizing their prior knowledge as they construct meaning while reading the expository texts in the English as the Second Language (ESL) classroom. In this case, the students are viewed as bringing personal meaning actively to the reading process. The reading comprehension lessons were carried out with a group of elementary students’ reading behaviours being observed and audio-recorded and the data were collected and analyzed qualitatively. The KWLS grid was used to assist students to activate their prior knowledge by generating questions and discussion to construct meaning while reading. Activating and developing prior knowledge presents background material supporting the importance of schemata and prior knowledge for literacy development. In short, the outcome of this research showed that comprehension can and should be taught. At this time, the challenge for the field is to mesh research with reality. Students of all ages.....
