Research ArticleOpen accessIn the author namesGastroprotective Effects of Melastoma malabathricum Aqueous Leaf Extract against Ethanol-Induced Gastric Ulcer Iin RatsFouad Hussain, Mahmood Ameen Abdulla, Suzita Mohd Noor et al.The gastro-protective effects of the aqueous leaf extract of Melastoma malabathricum was investigated against ethanol-induced gastric mucosal injuries in rats. There were four groups of adult sprague dawley rats, consisting of six rats per group. Macroscopically, oral administration of absolute ethanol to rats that had been pre-treated with only distilled water significantly produced extensive lesions of the gastric mucosa. Oral … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,774 accessesView PDFCite
Research ArticleOpen accessIn the author namesDesign of a Single-Phase Rectifier with Improved Power Factor and Low THD using Boost Converter TechniqueIsmail Daut, Rosnazri Ali, Soib TaibThe method of using Boost type of converter was proposed for a 300W single-phase rectifier in this paper. By designing the necessary techniques and methodology, the overall Power Factor (PF) and Total Harmonic Distortion would be improved to the expectation. The cause of having low PF and high THD for a diode-capacitor type of rectifiers is related to non-linearity of … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the author namesDynamical Analysis on the Transmission of Pertussis with Maternally Derived ImmunityAisha Aliyu Yakubu, Farah Aini Abdullah, Ahmad Izani Md Ismail, Yazariah Mohd YatimA susceptible-infected-recovered compartmental model incorporating maternally derived immunity compartment is analyzed in this study. The stability of the pertussis-disease-free and endemic equilibrium is studied. The basic reproduction number is obtained and its behavior analyzed by varying parameters. Numerical simulations indicated that when the waning parameter is increased, the frequency at which the population attains stability varies. However, the infected population … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 26 Jun 2020 · 6,294 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Role of SLC22A4 Gene Polymorphisms in the Response to Salbutamol in Asthmatic PatientsAlshymaa A. Ahmed, Nora M. Said, Alia A. El Shahaway, Nagwan A. IsmailResponse to Bronchodilators is influenced by many factors including genetics. To evaluate the influence of SLC22A4 gene polymorphisms (rs3792876 and rs2073838) on the response to inhaled salbutamol in asthmatic patients, bronchodilator response was assessed in 180 bronchial asthma patients via measuring changes of the Forced Expiratory Volume in one second (FEV1) after the administration of inhaled salbutamol and genotyping for … …American Journal of Immunology, Vol. 15, Issue 1 · 30 Jun 2019 · 7,470 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Lactate Treatments on Survival of Food-Borne Pathogens in Frozen Shrimp (Penaeus merguiensis)Alireza Shirazinejad, Noryati IsmailProblem statement: Sodium lactate treatments were evaluated for reducing population of pathogenic bacteria such as Salmonella enteritidis, E. coli O157:H7, Vibrio parahaemolyticus and Vibrio cholerae, inoculated on frozen shrimp (Penaeus merguiensis). Approach: Fresh shrimp were inoculated with the above pathogens, separately, at level of 105 CFU g-1 and appliedin sodium lactate solutions (NaL: 0.5% and 2.5% v/v) and 1% Lactic … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the author namesRobust Logistic Regression to Static Geometric Representation of RatiosAlireza Bahiraie, Noor Akma Ibrahim, A.K.M. Azhar, Ismail Bin MohdProblem statement: Some methodological problems concerning financial ratios such as non-proportionality, non-asymetricity, non-salacity were solved in this study and we presented a complementary technique for empirical analysis of financial ratios and bankruptcy risk. This new method would be a general methodological guideline associated with financial data and bankruptcy risk. Approach: We proposed the use of a new measure of risk, … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 8,216 accessesView PDFCite
Research ArticleOpen accessIn the author namesTracking Error Analysis of a Rotation-Elevation Mode HeliostatOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanFor the past few years, great efforts have been done in improving the tracking accuracy of a newly proposed rotation-elevation tracking mode heliostat. A special simulation program has been developed to systematically analyze the image movement and to find out the error of the parameters. In the simulation program, ray-tracing method was applied to work out the central point position … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,251 accessesView PDFCite
Research ArticleOpen accessIn the author namesSimplification of Sun Tracking Mode to Gain High Concentration Solar EnergyOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanPower conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, a new mode of sun tracking has … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,187 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordModeling the Nile: A Comprehensive Water Budget and Flow Assessment with the River Basin Flow Model (RBFM)Youssef Ismail HafezThe Nile River basin, covering 2.9 million km³ across 11countries, is one of the world's most complex hydrological systems. With an annual historical discharge of 84 billion m³ at Aswan, Egypt, and rainfall of around 1,660 billion m³ per year over the Nile basin, effective management of this vital transboundary resource requires a deep understanding of its hydrology. This study … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 18 Jun 2025 · 8,740 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNucleotide Sequence of the Coat Protein Gene of the Malaysian Passiflora Virus and its 3' Non-Coding RegionNorzihan Abdullah, Ismanizan Ismail, Vilasini Pillai et al.Problem statement: In this study, we identified the full length Coat Protein (CP) gene of the Malaysian Passiflora Virus (MPV) and its 3' non-coding region. The CP gene of the MPV contained 285 amino acid residues. Approach: Pairwise comparison of the MPV CP region with four other potyviruses, namely East Asian Passiflora Virus (EAPV), Passionfruit Woodiness Virus (PWV), Bean Common … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,723 accessesView PDFCite
