This paper presents analysis of the overall heat transfer inside exhaust port for port injection hydrogen fueled internal combustion engine (H2ICE). One-dimensional gas dynamics approach was used to describe the flow and heat transfer in the components of the engine model. The engine model was executed with variable engine speed of 2000 ≤ rpm ≤

The concentrations of phosphoric acid on the characteristics of high efficient activated carbon were investigated. Adsorptions capacities of activated carbon prepared by chemical method were carried out to evaluate the adsorptive of some heavy metals. It was found that treated (palm shell by sulphuric acid, 5%) raw material reduces contain of impur

Assessment for learning is a catalyst for reformation in instructional practices (Sahari, 1999), bridges theory and practices (Riley & Stern, 1998), and creates "a shared academic culture dedicated to assuring and improving the quality of higher education" (Ellyn, 2000, p. 2). This paper presents the findings of a national study conduct

Sonication treatment is used in the preparation of scaffold that elicitsminimal immune response after implantation. The aim of this study is to investigate the immunologic responseof sonicatedly decellularizedaortic scaffoldsafter 7 and 35 days of subcutaneousimplantation. In this study, aorta samples weresonicatedly decellularized in0.1% and 2% SD

This study was conducted to asses the impact of AKEPT’s Centre for Leadership in Learning and Teaching in facilitating and sustaining high quality instructional leadership through capacity building interventions. Among others, the objectives of this impact assessment project were to review the curriculum, levels of participations as well as to ex

Malaysia and Singapore are good examples of multicultural societies albeit with different acculturation ideologies. Both countries comprise three main ethnic groups but in diametrically opposite proportion. In Malaysia, 50.4% of the population is Malay, 23.7% Chinese, 11%indigenous peoples, 7.1% Indian, and 7.8% other races. In Singapore, the ratio

Objectives: To determine the total phenolic content, antioxidant and antimicrobial activities of the extracts from Calophyllum symingtonianum. Methods: The extracts were tested for their antioxidant activity by the DPPH radical scavenging assay and the β-carotene bleaching assay, while the antimicrobial activity was determined by disc diffusion me

Advancement and innovation in developing water filtering system enhances immensely in the field of water purification. In this study the acid treated rice husk ash was used as SiO2 source in the preparation of zeolite Y, a medium siliceous zeolite used as an ion exchangers in water treatment process. Purity, pore size distribution, FT-IR and SEM mi

Thermal and acid wash treatment of rice husk has been conducted 550 to 600 0C in air atmosphere and chemical treatments consisted of acid, H2SO4. Purity, pore size distribution, FT-IR and SEM micrographs of treated and non-treated samples are presented. In this study the acid treated rice husk ash was used as SiO2 source in the preparation of zeoli

Technology brings amazing changes in information and communication system. Most of the transportation operations have integrated technology to improve customer service. However, convincing customers to adopt new technology-driven businesses, such as ride-sharing apps, has become more challenging than ever. The current state of ride-sharing apps in
