Spatial and temporal dynamics of cyanobacteria and microcyctins in freshwater systems: implications for the management of water recources
Som Cit Si Nang
Excessive growth of cyanobacteria, commonly known as cyanobacterial blooms, appear to be increasing_ in magnitude and frequency worldwide, thus posing a serious threat to the safety and security of_ water resources. With the increasing global water stress, there is a need for effective management_ of cyanobacterial blooms in water bodies. So far, it has been a great challenge to mitigate and_ assess public health risks associated with cyanobacterial blooms due to difficulty in predicting_ the level of cyanobacterial biomass and microcystin concentrations in water bodies. Moreover, the_ effectiveness of the current bloom prevention and risk assessment strategies depend upon the_ understanding of the dynamics of cyanobacteria and microcystin under natural conditions. Thus, this_ research aims to: i) assess the variability of the relationship between cyanobacterial biomass and_ microcystin concentration, which is currently used to assess the risk to human and ecosystems_ health; ii) deter.....

Self-assembly of molecular wires on Au and Cu for molecular electronics
Aisyah Mohamad Sharif
Self-assembled monolayers (SAMs) of thiols, dithiols, or other bonding moieties are attractive   molecular  systems  with  expected  applications  in  novel  areas  such  as molecular electronics,  biotechnology and chemical and bio-sensing. With two thiol or two dicarboxylic acid moieties, with  aromatic and/or aliphatic backbone structures, these molecules have the ability to connect two  metal electrodes, and have been chosen for this fundamental work on molecular wires. Our work was first concerned with a study of the morphology and structure of self-assembled  monolayers of such molecules on Au(l 11), at low and at high molecular coverage. We used scanning  tunneling microscopy (STM) to investigate the self-assembly of two prototypic symmetric dithiols  (1,6-hexanedithiol and biphenyl-4,4'-dimethanethiol) from dilute aqueous solutions and were able to  correlate their growth with the deconstruction of the Au(111) herringbone pattern known to produce  a.....

Exploring public perception and acceptability of intelligent speed adaptation (ISA) in Malaysia
Noradrenalina Isah
Intelligent Speed Adaptation (ISA) is a promising technology for improving speed management and road safety. Despite its potential benefits, there is limited research on public perception and acceptance of ISA in Malaysia. This study employed a descriptive, cross-sectional framework and a tool constructed based on the available literature. Using an online survey of 776 respondents, this study explored how Malaysian drivers perceive and accept the ISA system as well as their level of knowledge about it. Descriptive statistics were performed using SPSS software to explore the data distribution and profile. The findings revealed that most respondents lacked knowledge and awareness about ISA, including their purpose to counter speeding (79.9%). Only 8.1% had a vehicle equipped with an ISA system, and 54.4% used navigation systems on their mobile phones. Most respondents were unsure about the impact of ISA on reducing vehicle emissions and enhancing fuel efficiency. Among the four types of .....

Penggunaan imbuhan-i dan -kan dalam novel perlumbaan kedua dan julia
Khushairi Fadzal
Pada tahun 2000 Kementerian Pendidikan telah menetapkan Komponen Kesusasteraan Melayu (KOMSAS) akan  menjadi sebahagian daripada mata pelajaran Bahasa Melayu. Melahn pengajaran KOMSAS ini pelajar akan  dapat mempelajari bidang interpersonal, bidang maklumat dan estetik. Mengikut sukatan baru ini  penumpuan pada bidang-bidang ini membolehkan para pelajar menggunakan bahasa Melayu secara berkesan  dalam kehidupan  harian,  bidang  pekerjaan  dan  sebagai  bahasa  ilmu.  Walaupun  tujuan  pengajaran KOMSAS kepada pelajar mempunyai tujuan yang baik, tetapi ada perkara-perkara yang perlu  diperhatikan terhadap teks KOMSAS ini. KOMSAS merupakan karya kreatif yang mempunyai kelonggaran  dalam aspek tatabahasa. Kajian ini dijalankan dengan tujuan untuk memperoleh maklumat tentang  penggunaan imbuhan -i dan -lean dalam novel Perlumbaan Kedua dan novel Julia. Maklumat yang akan  dikumpul nanti, adakah  penggunaan  imbuhan  -i  dan -kan dalam  novel tersebut  mene.....

Penguasaan perbendaharaan kata bahasa melayu murid tahun enam - kesan kedudukan sekolah, jantina, dan sosioekonomi keluarga
Manivannan Subramaniam
Kajian ini dilakukan  untuk melihat sejauh mana penguasaan perbendaharaan kata bahasa Melayu murid  darjah enam dan meninjau sama ada  wujud  perbezaan penguasaan  perbendaharaan kata antara murid di  bandar dan di luar bandar. Selain faktor  jantina  pengkaji  juga melihat   faktor  sosioekonomi   keluarga  yang mempengaruhi penguasaan perbendaharaan kata dalam kalangan murid.  Kajian ini  diadakan di dua lokasi yang berbeza. Sekolah Kebangsaan  Manjoi 1, Ipob  dan Sekolah Kebangsaan  Jalan Panglima Bukit Gantang , Ipoh mewakili kawasan bandar manakala Sekolah  Kebangsaan Jalan  Pengkalan Pegoh, Labat  dan Sekolah Kebangsaan Pengkalan Baru, Kampung Kepayang mewakili kawasan  luar bandar. Seramai 100 orang murid terlibat dalam kajian ini. Bentuk perbendaharaan kata yang  diberi tumpuan ialah kata nama, kata kerja, dan kata adjektif. Dapatan kajian menunjukkan, daripada  100 sampel hanya 46.00% murid sahaja dapat menggunakan lebih daripada min purata 1.....

Strategi pembelajaran bahasa melayu dalam kalangan pelajar asing
Sharala Subramaniam
Kajian ini memerihalkan strategi pembelajaran bahasa Melayu untuk penutur asing. Tujuan kajian ini  adalah untuk: (i) mengenal pasti strategi pembelajaran bahasa yang digunakan oleh pelajar asing  dalam mempelajari  bahasa Melayu di Malaysia, (ii) mengetahui nilai min bagi SPB yang digunakan  oleh pelajar asing yang berlainan budaya berdasarkan negara asal mereka dan (iii) mengenal pasti,  sama ada pelajar asing lebih bermotivasi instrumental atau integratif dalam pemilihan strategi  pembelajaran bahasa Melayu. lnstrumen soal selidik digunakan bagi mengumpulkan data. Seramai 173  orang pelajar asing yang mewakili enam buah negara telah dipilih sebagai responden kajian. Data  soal selidik dianalisis untuk menjawab soalan kajian. Dapatan kajian menunjukkan bahawa pelajar  asing lebih banyak memberi tumpuan di dalam kelas untuk menguasai bahasa Melayu. Strategi  pembelajaran bahasa yang digunakan oleh pelajar asing yang berlainan budaya berdasarkan negara  Nigeria, In.....

Assessment of obstetric ultrasound images using machine learning
Bahbibi Rahmatullah
Ultrasound-based fetal biometry is used to derive important clinical information for identifying IUGR (intra-uterine growth restriction) and managing risk in pregnancy. Accurate and reproducible biometric measurement relies heavily on a good standard image plane. However, qualitative visual assessment, which includes the visual identification of certain  anatomical landmarks in the image is prone to inter- and intra-reviewer variability and is also  time-consuming to perform. Automated anatomical structure detection is the first step towards the  development of a fast and reproducible quality assessment of fetal biometry images. This thesis  deals specifically with abdominal scans in the development and evaluation of methods to  automatically detect the stomach and the umbilical vem within them. First, an original method for detecting the stomach and the umbilical vem m fetal abdominal scans was developed using a machine learning framework. A classifier solution was des.....
