    Synthesis of palm oil based-urethane acrylate (POBUA) resins was carried out by acrylation of epoxidizedpalm oil (EPOP) using acrylic acid in the presence of a catalyst and followed by isocyanation to obtainthe POBUA. Using the monomer as a diluent in the formulation, 4% of photoinitiator and incorporationof organoclay (1-5% wt), nanocomposites were obtained upon UV irradiation. The X-ray DiffractoryXRD study revealed that the nanocomposites obtained were of the exfoliation type. The presence ofthe clay improved the hardness and did not affect the thermal stability. Similarly, it increased the glasstransition temperature Tg but reduced the modulus as the clay content was increased. The improvementof the tensile strength was only obtained when the clay concentration was 5 phr.

    A GIS-based user-interface programme was developed to compute the geospatial Water ProductivityIndex (WPI) of a river-fed rice irrigation scheme in Northwest Selangor, Malaysia. The spatial analysisincludes irrigation blocks with sizes ranging from 20 to 300 ha. The amount of daily water use for eachirrigation block was determined using irrigation delivery model and stored in the database for both mainseason (August to December) and off season (February to May). After cut-off of the irrigation supply,a sub-module was used to compute the total water use including rainfall for each irrigation block. Therice yield data for both seasons were obtained from DOA (Department of Agriculture, Malaysia) of thescheme. Then, the Water Productivity Index (WPI) was computed for each irrigation block and spatialthematic map was also generated. ArcObjects and Visual Basic Application (VBA) programminglanguages were used to structure user-interface in the ArcGIS software. The WPI, expressed in termsof crop yield per unit amount of water used (irrigation and effective rainfall), ranged from 0.02 to 0.57kg/m3 in the main season and 0.02 to 0.40 in off season among irrigation blocks, respectively. Thedevelopment of the overall system and the procedure are illustrated using the data obtained from thestudy area. The approach could be used to depict the gaps between the existing and appropriate watermanagement practices. Suitable interventions could be made to fill the gaps and enhance water useefficiency at the field level and also help in saving irrigation water through remedial measures in theseason. The approach could be useful for irrigation managers to rectify and enhance decision-makingin both the management and operation of the next irrigation season.

    Objective: The smoking rate among patients with mental health problem is higher than in the general population. Effective pharmacotherapy to treat nicotine addiction is thus needed to reduce the morbidity and mortality associated with cigarette smoking among these patients. This article reviews the literature on the suitability of varenicline for smokers with mental health problems.
    Methods: A search of the literature was conducted using PubMed from year 2001 to July 2009 using key words varenicline alone and varenicline and mental health. Articles chosen were narrowed to those published in English. The type of articles chosen included clinical trials, metaanalyses, case reports, and review articles.
    Results: The search produced a total of 322 articles on varenicline and 14 articles on varenicline and mental health. Varenicline, a new drug for smoking cessation is an α4β2 partial agonist and partial antagonist at nicotinic acetylcholine receptor. As a partial agonist, varenicline relieves craving and withdrawal symptoms that occur during smoking abstinence and also reduce the rewarding effects of smoking in patients who relapse. However, at present, there is concern regarding the neuropsychiatric side effects such as aggressive behaviour, suicidal ideation, mania and depression associated with varenicline use in patients with mental health problems, but these reports did not show a causal-link or lack of link between these symptoms and varenicline.
    Conclusion: Current available data support the effectiveness of varenicline to treat nicotine dependence. However its safety among smokers with mental health problems remains to be elucidated. At present, further safety assessment is needed in this patient population. Until new data is available regarding the safety of varenicline in these populations, psychiatrists and physicians prescribing this medication should be extra cautious and monitor for possible psychiatric side effects when prescribing this medication to patients with pre-existing psychiatric disorders or have vulnerability to psychoses.

    Recurrent boils are troublesome enough to children and their parents to be finally referred to the paediatricians. This study attempts to provide local data on epidemiology, pattern of infections of offending organism especially Staphylococcus aureus and underlying immunological abnormality. This condition does not appear to be related to socio economic status nor is staphylococcal nasal cariage a direct contributing factor. Defect in neutrophil function especially the respiratory burst assayed via chemiluminescence response to Staphylococcus aureus is closely associated with this condition. It is hoped that this data would be a further impetus for further research into this exciting field.

    Spatial and temporal variations in concentrations of several metals and isotopes in sediment cores from around Penang Island, an area with economically important biological resources off the northwest coast of peninsular Malaysia, are reported. Because of a typical, monazite rich mineralogy in surrounding drainage basins, sedimentary metal enrichment factors relative to global average materials, enrichment factors (EFs) of ˃1.0 do not always indicate significant anthropogenic metal inputs. Because of extensive metal solubilization in the hot, organic carbon rich area, EFs of < 1.0 may be observed for several metals despite significant anthropogenic contributions. Comparison of metal-Al relationships in Penang area surface sediments with those in nearby and presumed uncontaminated Strait of Malacca sediments more accurately correct for atypical regional solubilization and mineralogical effects than comparison to global average materials. Such comparisons show concentrations of Cd, Cu, Pb, Ni, Cr, As, Sb, Zn and V have changed by less than a factor of two by anthropogenic discharges. Sedimentary concentration profiles of Pb, Zn and Cu, ratioed to Sc to normalize for variations in grain size and mineralogy, have subsurface maxima suggestive of modest and recently reduced anthropogenic inputs. Mn, U, As and Sb have Sc-normalized concentration profiles clearly affected by diagenetic processes. Sc-normalized profiles of Cr, Th, Ce and Sm show only small changes with depth, confirming insignificant anthropogenic inputs and undetectable postdepositional diagenetic mobility.
    Excess ²¹⁰Pb activities and fluxes in Penang area sediments are limited by supply of this radionuclide, in contrast to sediments of both the northwestern U.S.A. and Amazon continental shelves, where they are limited by particle scavenging reactions.²¹⁰Pb activities in sediments of
    the shallow, dynamic Penang area often show erratic or unconvincing changes with depth that
    cannot be reliably modeled by assuming steady state, constant deposition rate of particles of
    uniform chemistry, mineralogy and initial unsupported ²¹⁰Pb, and that mixing is limited to a
    recognizable surface layer and resemble a diffusive process.

    Effects of different types of solvent on the antioxidant and antibacterial activity of Quercus infectoria extract have not been well documented. Therefore, extraction process was conducted using conventional Soxhlet extraction with six different types of solvent (100% methanol, ethanol, acetone, water and 70% methanol, and ethanol). High performance liquid chromatography was implemented to identify gallic acid and tannic acid in the extracts. Water extracts contained the highest concentration of both gallic acid and tannic acid compared to other types of solvent; 51.14 mg/g sample and 1332.88 mg/g sample of gallic acid and tannic acid. Meanwhile, antioxidant and antibacterial activity were tested using DPPH free radicals scavenging and disc diffusion assay. Results demonstrated that water extracts gave the highest antioxidant activity (approximately 94.55%), while acetone extract gave the largest inhibition zone for disc diffusion assay (19.00mm respectively). The results also revealed rich sources of gallic acid and tannic acid in Q. infectoria which might provide a novel source of these natural antioxidant and antibacterial activity.

    A numerical simulation and analysis was performed to investigate the effect of absorber and buffer layer band gap grading and on a Copper-Indium-Gallium-Diselenide (CIGS) solar cell. The software used is the Solar Cell Capacitance Simulator (SCAPS). The absorber and buffer layer energy band structures’ effect on the cell’s output parameters such as open circuit voltage, short circuit current density, fill factor and efficiency were extensively simulated. Two structures of the energy band gap were simulated and studied for each of the absorber and buffer layer. The simulation was done on the uniform structure in which the energy band gap is constant throughout the layer. It was then continued on the cell with graded band structure, where the energy band gap of the material is varied throughout the layer. It was found that the cell with graded band structure in absorber and buffer layer had demonstrated higher efficiency and better performance in comparison with the cell with uniform band gap structure.

    Hamartomatous polyps of the tonsil are very rare. They have been described using various terms such as a lymphangiomatous polyp, lymphangiectatic fibrous polyp, lipomatous polyp or pedunculated tonsil, thus the actual incidence is difficult to be quantified. We present a case of hamartomatous polyp of the palatine tonsil in a 30-year-old female presented with recurent tonsillitis. Histopathological examination of the resected tonsils showed features of chronic tonsilitis with incidental finding of hamartomatous polyp characterized by a polypoidal tissue covered by stratified squamous epithelium and composed of thin-walled blood vessels, lymphatic channels, fibrofatty tissues, seromucinous glands and striated muscle fibres. An unusual incidental histopathological finding of a rare condition has been discussed along with the review of literature.

    Two species of plants, Andrographis paniculata and Euphorbia hirta were screened for antibacterial activities against three Gram positives and Gram negatives. The leaves from both plants were extracted by methanol extraction. The antibacterial activity was detected with spread plate well diffusion method. The extracts of both plants demonstrated inhibitory activity against both Gram negative and positives bacteria. Staphylococcus aureus, Bacillus subtilis, Streptococcus epidemidis, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. The minimum inhibitory concentration (MIC determination using micro dilution method showed that the A/tic of A. paniculata for the tested bacteria were 1.56 mg/ml (Staph. aureus), 3.13 mg/ml (Bacillus subtilis), 3.13 mg/ml (Strept. epidemidis), 1.56 mg/ml (Escherichia cob), 12.50 mg/ml (Klebsiella pneumoniae) and 3.13 mg/ml (Pseudomonas aeruginosa) respectively. The MIC value for E. hirta was 6.25 mg/ml (Staph. aureus) and 3.13 mg/ml (Bacillus subtilis), 3.13 mg/ml (Strept. Epidemidis), 3.13 mg/ml (Pseudomonas aeruginosa),12.5 mg/ml (Escherichia coli), and 6.25 mg/ml (Klebsiella pneumoniae). Both plants represent a potential for pharmaceutical and agricultural applications and are worthy of further study.

    We report a case of a 7-year-old girl who initially presented with painless right eyelid swelling with full extra-ocular movement (EOM). She was treated with intravenous broad-spectrum antibiotics for preseptal cellulitis but her condition worsened. An urgent magnetic resonance imaging (MRI) of the brain and orbit showed orbital abscess, subperiosteal abscess in the medial orbital wall and evidence of sinusitis in the anterior ethmoidal air cells. She underwent Endoscopic Orbital Decompression (EOD) surgery on day 4 of presentation and her condition improved remarkably. We report a case of orbital abscess with subperiosteal abscess in the medial orbital wall. This case highlights the possibility of progression of orbital cellulitis despite administration of a broad-spectrum antibiotic.

    Obesity is a well-established risk factor for cardiovascular disease. The objective of
    the study was to determine the prevalence of obesity and factors associated among secondary school students aged between 13 to 17 years at Slemani City Centre, Iraq. Methodology: A cross sectional study design was used. The calculated sample size was 1656. Probability proportional to size sampling technique was used to select the sample. A validated pretested questionnaire was used to collect the data. Weight and height were also taken. Data were analyzed using SPSS version 21. Chi-square test was used to determine an association between two categorical variables. Independent t-test was used to compare two means. Multiple logistic regression was used to determine the predictors for obesity. Results: The response rate was 92.54% and the overall mean age of the 1588 respondents was 15.42 (95% CI = 15.35, 15.49) years. The prevalence of overweight and obesity was 20.6% and 11.3% respectively. Variables significantly associated with overweight and obesity (age, monthly family income, education level of parents, body part satisfaction and body size perception) were entered into the logistic regression model. Multiple logistic regression analysis showed that the predictors for overweight and obesity were age, monthly family income, body part dissatisfaction and body size perception. Conclusion: The prevalence of overweight and obesity is high (20.6% and 11.3% respectively). The predictors of obesity among secondary school students aged between 13 to 17 years old at Slemani City Centre Kurdistan Region, Iraq were age, family income and body image dissatisfaction.

    Objective: A sizable body of criminology literature has suggested that personality factors are critical to the development of aggressive behaviour. While research on personality focusing on aggression often revolves on "Eynseck Three Factor Model" and "Big Five Model", research on "Alternative Five Factor Model" (AFFM) is rather inadequate. Objective: The present study aimed to examine the association between five types of personality traits and subscales of aggression. Methods: This observational cross-sectional study was conducted in two prisons in Peninsular Malaysia among 198 Malay adult male inmates. The participants were selected based on the purposive sampling method from those who were convicted for various types of crime. Two psychometric instruments adapted to the Malaysian context were used: Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Culture (ZKPQ-M-40-CC) and Aggression Questionnaire (AQ-M). Pearson correlation coefficient test was conducted to determine the association between five types of personality traits and subscales of aggression. Results: The results showed that there was a significant association between certain types of personality traits and subscales of aggression. The results were discussed in relation to theory and the context of crime. Conclusion: There is evidence that personality traits are linked to aggressive behaviour which may lead a person to commit offenses.

    Apart from environmental and social factors, psychological traits is largely linked with criminal and delinquent behaviour. The purpose of this article is to review four critical psychological traits of individuals that may lead to criminal behaviour in a nutshell. Methods: An archival research methodology was employed in this study where relevant search for literatures on these four psychological traits was made across search engines such as Google Scholar with relevant articles selected for this review. The literatures were microscopically reviewed in order to demonstrate the linkage between psychological traits and criminal behaviour. Results: Four psychological traits: personality trait, low selfcontrol, aggression behaviour, and cognitive distortion were chosen to address such linkages. All these four traits were discussed thoroughly in relation to crime and criminality contexts. Conclusion: It is crucial to understand the role of these traits and in-depth understanding of each psychological trait with relation of criminal behaviour offers an opportunity to the public at large to expand their knowledge on the importance of practicing and equipping oneself with healthy psychological traits to hinder from criminal and delinquent acts.

    Introduction: Crime is an immoral act capable of tearing the well-being of society and the nation. Various factors have been accredited as potential factors for crime engagement for example natural inclination, nurture or a combination of these factors. Within the domain of natural inclination, lack of self-control is often viewed as the primary cause of crime and delinquency. However, there are no valid and reliable Malay language psychometric instruments to measure the level of self-control among Malaysians.
    Objective: The aim of this study was to validate the Self Control Scale (SCS) for use among Malay speaking populations. Henceforth the Malay language version is identified as SCS-M.
    Method: A cross-sectional study was carried out on 150 inmates incarcerated within two prisons in Peninsular Malaysia in June 2012. Forward and Backward translations of the original SCS were carried out followed by content and face validation processes. Exploratory factor analysis and Cronbach's Alpha reliability analysis were performed.
    Result: Both content and face validation processes showed promising and good outcomes. Preliminary analysis for factor analysis supported factorability of the items. The factor loadings of SCS-M items did not correspond to the original six SCS dimensions. Since SCS is often administered as a unidimensional scale, a forced one factor analysis was performed and items with factor loadings exceeding 0.3 were retained. The result of internal consistency reliability of SCS-M demonstrated a good Cronbach's alpha value of 0.80.
    Conclusion: The findings supported that SCS-M is a valid and reliable unidimensional scale to measure the level of self-control among Malay speaking populations. It is anticipated that the emergence of SCS-M is vital for self-control assessment, treatment, and rehabilitation purposes.

    The reciprocal translocation t(9;22)(q34;q11) which gives rise to the Philadelphia (Ph1) chromosome and BCR/ABL fusion gene, plays a pivotal role in the diagnosis and pathogenesis of chronic myeloid leukemia (CML). In this study, we evaluated the role of fluorescence in situ hybridisation (FISH) in detecting the BCR/ABL rearrangement in CML patients. The sensitivity, specificity and detection rate of BCR/ABL gene using FISH, PCR and conventional cytogenetics (karyotyping) methods were also compared. 18 bone marrow samples of patients with clinically diagnosed CML and suspected of CML were collected. The sensitivity, specificity and positive predictive values of FISH were altogether 100% while the sensitivity, specificity and positive predictive values for conventional cytogenetics (karyotyping) were 85%, 100% and 100% respectively. Convetional cytogenetics (karyotyping) detected an additional chromosomal aberration in addition to the Ph1 chromosome. In conclusion, FISH is a highly sensitive method in detecting the BCR/ABL gene. Conventional cytogenetics (karyotyping) remains an important investigation in the work up of suspected CML patients since there is a possibility of detecting chromosomal aberrations in addition to the Ph1 translocation. Therefore, conventional cytogenetics (karyotyping) and FISH are complementary techniques and their results should be interpreted together with clinical information.

    Identifi cation of unknown suspect through bite marks has always been challenging. Narrowing list of suspects through sex and race markers is always recommend but rarely utilized due to limited publication in this area. Thus, this preliminary research was aimed to study the difference of bite mark made on dental wax between sex and race. A sample size of 40 UKM undergraduates comprising of Malay (male = 10, female = 10) and Chinese (male = 10, female = 10) were used in this study. Bite mark of subject was obtained through dental wax, digitally scanned and analyzed using Image-J software. Parameters measured were anterior teeth size, intercanine width and anterior teeth relative rotation. Result indicated that mandible left canine tooth size had signifi cant sexual dimorphism (p < 0.05) in differentiating sex. The means for male and female measured were 4.63 ± 1.05 mm and 5.35 ± 0.87 mm respectively. In addition to the result, tooth size of maxillary left canine and mandible left lateral incisor were signifi cantly different (p < 0.05) between races. Means for mandible left canine Malay and Chinese were 5.27 ± 1.01 mm and 4.50 ± 1.22 mm respectively. Furthermore, left lateral incisor mandible had means of 5.15 ± 0.87 mm and 4.60 ± 0.74 mm for Malay and Chinese respectively. Unfortunately, there were no signifi cant differences for intercanine width and anterior teeth relative rotation between the two major races in Malaysia. In conclusion, this research has demonstrated the possibility of using tooth size of mandible left canine, maxillary left canine and mandible left lateral discriminate sex and race.

    In this study polymer electrolytes composed of poly(methyl methacrylate) (PMMA) as a host polymer and ethylene carbonate (EC) as a plasticizer complexed with different lithium salts, i.e. lithium tetrafluoroborate (LiBF4) and lithium triflate (LiCF3SO3) were prepared by the solution casting technique. The conductivities of the films were characterized by impedance spectroscopy. At room temperature, the highest conductivities were 4.07 × 10–7S cm–1 and 3.40 × 10–5 S cm–1 achieved, respectively from the films containing 30 wt% LiBF4 in the PMMA-EC-LiBF4 system and 35 wt% LiCF3SO3 in the PMMA-EC-LiCF3SO3 system. The conductivity-temperature dependence of the films seemed to obey the Arrhenius equation in which the ion transport in these materials was thermally assisted. Scanning electron microscopy analysis showed that the surface of PMMA-EC-LiCF3SO3 film was smooth and homogeneous, hence lithium ions could traverse through the PMMA-EC-LiCF3SO3 film more easily compared to the PMMA-EC-LiBF4 film. X-Ray diffraction studies revealed that complexation had occurred and the complexes formed were amorphous.

    A molecularly imprinted polymer (MIP), with the ability to bind Pb(II) ion, was prepared using the non-covalent molecular imprinting methods and evaluated as a sorbent for the Pb(II) ion uptake. 4-vinylbenzoic acid was chosen as the complexing monomer. The imprinted polymer was synthesized by radical polymerization. The template (Pb(II) ions) was removed using 0.1 M HCl. As a result, the efficient adsorption was found to occur at pH 7. The result also showed the applicability of the Langmuir model for the sorption, with the maximum sorption capacity of 204.08 μg/mg.

    In this study, an anaerobic mesophilic bacterial strain, namely Clostridium butyricum KBH1, was isolated from a natural source. This strain grew well and produced biogas with an average hydrogen concentration of 60% (v/v) in the Reinforced Clostridial Media (RCM). To study the basic nutrient requirements, three main nutrients namely peptone (Pep), yeast extracts (Yes) and glucose (Glu) were chosen as factors, using an experimental design. The experiments were run according to 23 Full Factorial Design, followed by the Response Surface Method (RSM). The fermentation was performed in 30 ml serum bottles with 20 ml working volume in a sterile and anaerobic condition at 37°C with 5% inoculums. The results from the Analysis of Variance (ANOVA) for the factorial design showed that all the three factors had significantly affected the gas production by the C. butyricum. The response surface plot of the gas production by C. butyricum showed that the gas production could be enhanced by increasing peptone and yeast extract concentrations up to 15 g/l and 24 g/l respectively, without showing any substrate inhibition. Meanwhile, the glucose concentration showed an optimum at the middle point (8 g/l) with possible substrate inhibition at a high concentration (12 g/l). The total biogas production could be correlated to the three factors, using the quadratic equation: Gas =0.17 + 7.11Glu - 0.02Pep + 0.77Yes - 0.53Glu2 + 0.09Glu*Pep. The experimental results showed that the strain could grow well in substrate with high organic nitrogen content such as POME and might be not suitable for substrate with high sugar content due to substrate inhibition.
