    Nowadays, we face the problem regarding the depletion of oil and gas but at the same time, final energy consumption grew at a fast rate of 5.6 percent between 2000 and 2005 to reach 38.9 Mtoe in 2005. A substantial portion of the energy consumed was from oil (63 percent) which was mainly utilized in the transport and industrial sectors. Natural gas consumption also increased in a rapid manner to fuel electricity demand. The share of natural gas in total installed electricity generation capacity remains high at 70 percent in 2005, but has fallen slightly from 77 percent in 2000. Malaysia is endowed with conventional energy resources such as oil and gas as well as renewable like hydro, biomass and solar energy. At 2005 production levels, proven oil reserves are expected to last another 19 years while natural gas reserves are expected to last for about 33 years. Taking into account the growing energy consumption and domestic energy supply constraints, Malaysia has set sustainable development and diversification of energy sources, as the economy's main energy policy goals. The Five-Fuel Strategy recognises renewable energy resources as the economy's fifth fuel after oil, coal, natural gas and hydro. The introduction of biodiesel for the transport sector in 2005 is one of the positive steps that the government has undertaken to achieve sustainable energy development through diversification of fuel sources. We need to do something to overcome the problem of depletion of oil and gas that affect the energy supply in the future. One of the way is by doing the scenario planning. There are lots of method that can be used to create scenario planning. Two of them are Business As Usual (BAU) and Green Future (OF). In this project, I will used this two method for energy scenario planning in Malaysia

Dapatan kajian juga menunjukkan terdapat hubungan yang signifikan antara keputusan terkini dalam mata pelajaran Biologi dengan pencapaian markah konsep pembahagian sel

    Development of sprayer nozzle of The unpacked saturator for dissolved air flotation process.

    Get PDF
    Dissolved air flotation (DAF) process becomes prominent in water treatment technology all over the world. This process had been well-accepted as an alternative for sedimentation due to its potential to remove very small or light particles in a shorter period, simplicity of the design and only required less area. Proses pengapungan udara terlarut semakin meluas dalam aspek rawatan air di seluruh negara. Proses ini semakin diterima dengan baik sebagai satu altematif kepada proses pemendapan kerana potensinya dalam menyingkirkan partikel-partikel yang keeil serta ringan, rekabentuknya yang ringkas dan hanya memerlukan kawasan yang kecil

    Building a unique online corporate identity

    Get PDF
    Purpose: The purpose of this paper is to examine the current state of mission and vision statements on corporate websites of Malaysian and Singaporean corporations based on Aaker's brand personality dimensions and analyze how the dimensions are effectively used to develop a unique corporate identity. Design/methodology/approach: Content analysis is employed to examine similarities and differences for 300 Malaysian and 214 Singaporean consumer corporations based on Aaker's big five brand personality framework. Findings: Generally most companies tend to publish and communicate their mission and vision statements visibly to general stakeholders. First, both Malaysian and Singaporean companies have weak brand personality dimensions which reflect the projection of corporate identity of companies. Second, there is a significant difference in the brand personality dimensions between Malaysian and Singaporean consumer corporations. Finally, evidence showed that most Malaysian and Singaporean companies rather failed to position themselves in the marketplace using brand personality dimensions in their vision and mission statements. This may affect their overall organizational direction in building a unique corporate identity and gaining competitive advantages within the context of a global business environment. Practical implications: The study acknowledges the increase in communicating the mission and vision statements on the corporate websites of Malaysian and Singaporean corporations. However, there is a need for corporations in Malaysia and Singapore to orchestrate their core competence in order to develop a unique corporate identity in a global business environment. Originality/value: The study contributes to the corporate identity literature in providing an insight into how corporations communicate the desired brand personality through their websites for the critical inquiry of the dominant coalition and main stakeholders

    Get PDF
    The study investigates how interactional metadiscourse resources are used to articulate and construct gender identity among ESL learners in Malaysia. The main purpose of the study is to provide language practitioners with empirical data of how gender is projected in the academic writings of ESL learners and to what extent learners’ writings are affected by their gender. The data can then be utilised for the design and development of more effective academic writing courses in Malaysia. Quantitative and qualitative analyses were performed on the similarities and differences in the use of interactional metadiscourse resources, namely; hedges, boosters, attitude markers, engagement markers and self mentions between male and female ESL learners involved in the study. The findings of the quantitative analyses show no obvious differences in the writing style of female and male writers in the study, while the qualitative findings reveal slight differences in the way writers position themselves in the reader/writer interaction and in the expression of agreement statement

    Occurrence of Campylobacter and Salmonella in ducks and duck eggs in Selangor, Malaysia

    Get PDF
    The importance of Campylobacter and Salmonella as foodborne pathogens is well recognised globally. A recent work in Penang found ducks in commercial farms were infected with these organisms. The aim of the study was to detect the presence of Campylobacter and Salmonella in ducks and Salmonella in duck eggs in farms in a small part of Selangor. Cloacal swabs were obtained from 75 ducks and 30 duck eggs from three farms. The isolation and identification of Campylobacter and Salmonella were done using conventional methods. Twelve percent of Campylobacter and 16.0% of Salmonella were isolated from the ducks sampled. Salmonella was absent on and in eggs. Campylobacter isolates consisted of 22% Campylobacter jejuni and the remaining was Campylobacter coli. Three Salmonella serovars identified were Salmonella Agona, S. Braenderup and S. Corvallis. The presence of Campylobacter and Salmonella in ducks may cause contamination of the meat during processing and handling which can constitute public health hazard. Moreover, the farm workers may be exposed to the organisms through contact with the infected animals

    Normal soaking extraction (NSE) of rotenone from Derris elliptica

    Get PDF
    Derris elliptica or the tuba plant contains rotenone, bio-active compound known that has the potential to be used as bio-pesticide. Bio-pesticide is the best-known alternative bio-pesticide which has the potential to replace the use of conventional pesticides, as it is more environmentally friendly. The main objective of the paper is to obtain the best extraction solvent for optimizing the yield in rotenone extraction. Rotenone was extracted from Derris root using three different parts of roots and three types of solvent in Normal Soaking Extraction (NSE). The types of Derris roots are: (1) Fine root (2) Coarse root (3) Stem. The three types of solvent system are: (1) Acetone 95 % (v/v), (2) Chloroform 99.9 % (v/v) and (3) a mixture of ethanol: H2O (9:1) added with oxalic acid (1mg/ml). The liquid crude extracts were further cleaned up to remove the fine debris of roots. The presence of rotenone was confirmed using qualitative analysis Thin Layer Chromatography (TLC) and thereupon the determination of rotenone content was carried out using High Performance Liquid Chromatography (HPLC). From the results obtained, it was found that the Normal Soaking Extraction (NSE) using acetone 95 % (v/v) was the best method to extract the highest yield of rotenone; 1.14 % (w/w)
