Analysis Of Plastic Debris On Malaysia Beaches / Liyana 'Izzati Aris, Aris Liyana 'Izzati Jan 2012

Analysis Of Plastic Debris On Malaysia Beaches / Liyana 'Izzati Aris, Aris Liyana 'Izzati

Student Works (2010-2019)

Plastic debris is the main cluster of solid waste component present in the marine environment. Anthropogenic activities namely recreational and fishing activities are believed to contribute to the abundance of plastic debris (1 – 30 mm in size) especially along the beach. This study was undertaken to quantify and assess the degree of plastic debris buried in sand according to size with a view to classify such debris deposition at some Malaysian beaches. Another objective, the abundance distribution of the buried plastics was also studied in relation to the tidal zones of the beaches. Six selected beaches (in three different …

The Efficacy Of Alignment-Based And Alignment-Free Methods In Reconstructing Phylogenetic Trees Using Complete Mitochondrial Dna Sequence / Elham Yousef Kalafi, Elham Yousef Kalafi

Student Works (2010-2019)

Similarity searching tools are generally divided to two distinct groups: Alignment-based and alignment-free methods. There is no standard comparison between alignment-based and alignment-free methods` performance. In this project, I compared CLUSTALW, T-COFFEE and MUSCLE algorithms with four alignment-free methods, Kr, D2, D2z and MplusD to find out which of these methods are more efficient with respect to time and accuracy. In both alignment-based and alignment-free, results are represented by phylogenetic trees. Here, all phylogenetic trees are compared against the reference tree to determine how accurate the methods are. I found that alignment-based methods were the most accurate comparing to alignment-free …

Student Works (2010-2019)

We studied bacterial community structure in three different sewage treatment plants (STPs), namely STP 1, 2 and 3, in Klang Valley. STP 1, 2 and 3 were located in residential, commercial and light-industrial areas, respectively. Cu and Pb pollution detected in STP 3 was shown to affect its sludge production and biomass. Investigation by 16S rRNA PCR-DGGE demonstrated that bacterial community structures in the three STPs were different; and heavy metal resistant bacteria were predominant at STP 3. In order to determine the effects of heavy metal pollution on bacterial community structures, we used the canonical correspondence analysis, and showed …

Student Works (2010-2019)

MicroRNAs are ~20-22nt non protein-coding RNA regulatory genes that posttranscriptionally regulate many protein–coding genes to influence critical biological and metabolic processes. While the number of known microRNA is increasing, there is no published data for microRNA in freshwater prawns (Macrobrachium rosenbergii) a commercially cultured and economically important food species. Through deep parallel sequencing and an in silico data analysis approach, 327 miRNA families have been identified from small RNA libraries with reference to both the de novo transcriptome of M.rosenbergii obtained from RNA-Seq and to miRBase (Release 18.0, November 2011).

Obesity Study In Malaysian Malays With Focus On Candidate Genes And Biomarkers / Yamunah Devi Apalasamy, Yamunah Devi Apalasamy

Student Works (2010-2019)

Obesity is in rising prevalence globally and it has been associated with high mortality rate and other comorbidities. Obesity is a highly heritable disorder but genes responsible for hereditary variations remain to be largely elusive. Recent findings have shown that single nucleotide polymorphisms (SNPs) in the following genes predispose to the increased risk of obesity and obesity-related traits: leptin (LEP), melanocortin-4 receptor (MC4R), β2-adrenoceptor (ADRB2), insulin-induced gene 2 (INSIG2), syndecan 3 (SDC3), fat mass and obesity associated (FTO), resistin (RETN) and adiponectin (ADIPOQ). Biomarkers such as adiponectin, leptin and resistin have been shown to be tightly linked to obesity related …

Collocational Error Types In The Writing Of Iranian Efl Students / Marjan Ahmadi, Marjan Ahmadi Jan 2012

Collocational Error Types In The Writing Of Iranian Efl Students / Marjan Ahmadi, Marjan Ahmadi

Student Works (2010-2019)

Collocations are one of the most important concerns in EFL classes and materials. The significance of second language learners possessing some knowledge of collocaitons is now widely recognized. The learning of collocations can provide advantages such as increasing learners‟ language competence and also enhancing learners‟ communicative competence. Hence collocation knowledge is essential for EFL learners while collocation instructions in EFL courses become a necessity. EFL learners such as Persian learners of English make many collocational errors in their writing and in their speaking due to a lack of collocation competence in English. For instance, Persian/Iranian EFL learners say “learn knowledge” …
