The role of the public accounts committee in enhancing government accountability in Malaysia
This chapter provides an overview of the institutional framework of Malaysia's federal Public Accounts Committee (PAC), and the Committee's role in enhancing public sector
accountability. The development of the PAC and its relationship to the government structure in Malaysia are discussed alongside other institutions within the administrative framework of accountability. These include the Accountant General's Department and the National Audit
Department. A description of the PAC's powers, responsibilities, membership and working practices precedes a discussion on its effectiveness in supporting the enhancement of accountability. In addition, this chapter also cites cases examined by the PAC that were highlighted in the media
Application Of Digital Camera Data For Air Quality Detection.
Air pollution problem becomes increasingly critical in this present-day, whether in the developed or developing countries. Air management is one of the important issues in this 21st century. Malaysia is also affected by this problem
Remote Sensing Of Pm10 From Landsat Tm Imagery.
Air pollution concentration has been estimated over Penang Island from Landsat TM 7. In-situ measurements of the corresponding air pollution parameter (particulate matter less than 10 micron, PM10) were carried out simultaneously with the acquisition of the satellite imagery
Flexible Wearable Antenna on Electromagnetic Band Gap using PDMS substrate
A robust and low-profile electromagnetic band-gap (EBG) based on flexible wearable antenna covering 2.4 GHz frequency band is presented. The incorporated EBG with antenna reduces the radiation into the human body around 17 dB and decreases the impacts of frequency detuning. The overall dimension of the antenna integrated with EBG is 56 x 56 x 4 mm3 with relative impedance bandwidth of 8.3% is achieved. The proposed design has improved the gain up to 7 dBi. Specific absorption rate (SAR) assessment is also studied to certify the performance of the antenna when it is located proximity to human tissue. The flexible antenna with aforementioned performances could be chosen as a good candidate for integration into a range of wearable devices for medical application
Determination Of Aerosol Optical Thickness From Spectral Sky Transmittance.
The objective of this study is to test the feasibility of the proposed technique for retrieving spectral aerosol optical thickness (AOT) from the spectral transmittance measurements. The measurements have been acquired around Penang Island, Malaysia. Ground-based measurements were made with a handheld spectroradiometer. The measured spectral transmittance data were then converted to AOT values 6 spectral bands between 400 and 900 nm. Spectral AOT maps were generated using Kriging interpolation method for the 6 spectral bands. Air quality map was produced using this technique
Causative failure factors of communications management in mixed-use development projects in Malaysia
Construction delay has been a persistent challenge for the Malaysian construction industry. This has resulted in many issues, including public complaints, government loss of reputation and income and a decline in the gross domestic product output of the industry. Furthermore, the construction industry is a complex business with several stakeholders continually sharing information. Hence, ensuring project success has to be the utmost important task of a project manager. Often the construction industry is marred by high cases of delays, overruns, poor quality, health and safety issues, emissions and sustainability issues as a result of ineffective communication practices. Therefore, this paper aims to examine causative failure factors of communications management in mixed-use development projects in Malaysia. Based on the literature review, 11 factors and 44 items were identified. These factors and items were evaluated by 141 respondents from the Malaysian construction industry. Data analysis was done using SPSS 23.0. This study found that the most critical causative failure factor is team meeting discussions. The respondents believe that there is lack of stakeholder cooperation due to poor representation during the discussions, which also reflects the inadequacy of mutual respect, confidence and trust among stakeholders. As a recommendation, frequent team meeting discussions provide a platform for effective information exchange, thus help to reduce mixed-use project failures in Malaysia
PM10 Retrieval From Spectroradiometer Measurements.
This study attempts to determine the aerosol optical thickness (AOT) from spectroradiometer data. The spectroradiometer is used to measure the atmospheric transmittances in a wide spectrum over Penang Island, Malaysia
Protection induced by external Ca +2 application on proline accumulation, ion balance, photosynthetic pigments, protein and ABA concentration of mustard seedlings (Sinapis alba L.) under salinity stress
ABSTRACT The effect of external Ca 2+ application of different concentration to salinity-treated (100 mM NaCl) mustard plant (Sinapis alba L.) was investigated in relation to ion uptake, proline, chlorophyll a&b, protein and ABA concentrations. Salinity treatment (100 mM NaCl) led to significant decreases in Ca 2+ & K + uptake and Chl. a&b contents, accompanied by significant increases in Na + uptake, proline and ABA concentrations. Salinity treatment also induced the appearance of new protein bands. The most effective concentrations of CaCl 2 treatment in protecting mustard plants against the adverse effect of NaCl salinity were 5, 10, and 15 mM CaCl 2 . This could be attributed to the effect of CaCl 2 in decreasing ABA concentration, the synthesis of new polypeptides and increasing K + and Ca 2+ uptake
Multi-Parameter Entanglement in Femtosecond Parametric Down-Conversion
A theory of spontaneous parametric down-conversion, which gives rise to a
quantum state that is entangled in multiple parameters, such as
three-dimensional wavevector and polarization, allows us to understand the
unusual characteristics of fourth-order quantum interference in many
experiments, including ultrafast type-II parametric down-conversion, the
specific example illustrated in this paper. The comprehensive approach provided
here permits the engineering of quantum states suitable for quantum information
schemes and new quantum technologies.Comment: to appear in Physical Review
The rarity of terrestrial gamma-ray flashes
We report on the first search for Terrestrial Gamma-ray Flashes (TGFs) from altitudes where they are thought to be produced. The Airborne Detector for Energetic Lightning Emissions (ADELE), an array of gamma-ray detectors, was flown near the tops of Florida thunderstorms in August/September 2009. The plane passed within 10 km horizontal distance of 1213 lightning discharges and only once detected a TGF. If these discharges had produced TGFs of the same intensity as those seen from space, every one should have been seen by ADELE. Separate and significant nondetections are established for intracloud lightning, negative cloud-to-ground lightning, and narrow bipolar events. We conclude that TGFs are not a primary triggering mechanism for lightning. We estimate the TGF-to-flash ratio to be on the order of 10^(−2) to 10^(−3) and show that TGF intensities cannot follow the well-known power-law distribution seen in earthquakes and solar flares, due to our limits on the presence of faint events
