| 91 | 2009 Thesis | The nonabelian tensor squares of certain Bieberach group with cyclic point group pf order two Rohaidah Masri The torsion free crystallographic groups are called Bieberbach groups. These groups are extensions
of a finite point group and a free abelian group of finite rank. The rank of the free abelian group
is the dimension of Bieberbach group. In this research, Bieberbach groups with cyclic point group
of order two and Bieberbach groups with the elementary abelian 2-group C₁ x C₁ as the point group
are also considered. These groups
are polycyclic since they are extensions of polycyclic groups. Using computational methods
developed before for polycyclic groups, the nonabelian tensor squares for these Bieberbach groups
are determined. The formulas for the nonabelian tensor squares of four Bieberbach groups with
cyclic point group of order two and two Bieberbach groups with the elementary abelian 2-group C₁ x
C₂ as the point group are given. For the abelian
nonabelian tensor square, the formula obtained can be extended to calculate the nonabelian tensor

| 92 | 2012 Thesis | 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..... 76 hits |
| 93 | 2013 Thesis | 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

| 97 | 2024 Article | 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 ..... 62 hits |
| 98 | 2004 Thesis | 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..... 62 hits |
| 99 | 2004 Thesis | 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..... 59 hits |
| 100 | 2012 Thesis | 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
