This meta-analysis analyzed the prevalence of diarrheoal diseases among children less than fiveyears in three selected Eas African countries from 2012–2017. Search engines used Google Scholar, Proquest,and PubMed. Primarily, 300 studes were selected; hence 297 were eliminated using inclusion and exclusion criteria. The PICO (population, intervention, comparison, and outcome) guide helped in the analysis of the three selected stdies. The prevalence of diarrhoea among children less than fiveyears in the three selected EastAfrican countries from 2012 to 2017, averaged to 27% range from a minimum of 11% to a maximum of 54% of the 5478 total respondents (OR 2.07).

Evaluation Of Cooking Oil As Processing Addtive For Natural Rubber, Syamin Y. M., Azemi S., Dzaraini K.
ASEAN Journal on Science and Technology for Development
It was reported recently that high amount of aromatic ring or number of polycyclic aromatic hydrocarbon compounds found in aromatic oil are carcinogenic. This paper discusses the work to evaluate the Malaysian cooking oil as an alternative option to be used as process oil since cooking oil is safe to use and non-toxic. The performance of cooking oil is compared againstaromatic and paraffinioils. The results showed that rubber compounds containing cooking oil produced almostsimilar cure characteristicsas those produced by aromatic and paraffinioils indicating that it did not interfere with the vulcanization reaction. The physical properties of the vulcanizates containing cooking …
Hydrocarbons As Refrigerants―A Review, Koh J. H., Zakaria Z.
Hydrocarbons As Refrigerants―A Review, Koh J. H., Zakaria Z.
ASEAN Journal on Science and Technology for Development
Refrigerants used in air conditioning and refrigeration (AC&R) indusries have come full circle since the beginning of the industrialrevolution. With concern on issues relating to the environment such as the global warming and climate change issues, we should finda better alternative than to continue using these refrigerants that cause global warming and ozone depletion. AC&R industryplayers have blended in by introducing some new equipment and components that are specificallydesigned for hydrocarbon (HC) use. Mostnew refrigerators sold in Malaysia are already equipped with isobutane [a hydrocarbon designated as R-600a by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards]as …

ASEAN Journal on Science and Technology for Development
Malaysia is the largest producer and exporter of examination and surgical gloves in the world and currently faced with mitigating large amounts of waste generated during the glove production process. This waste is mainly generated from glove dipping tanks and is referred as dipping tank coagulum (DTC). It is considered as scheduled waste which requires mandatory disposal by incineration, in compliance to the Scheduled Waste Regulations set by the Department of Environment. Work described in this study showed, DTC samples with a polymer content of >40%, both ash and calcium carbonate content of <10% and curatives <2% (Sulphur, antioxidants, accelerators and ZnO) when blended with virgin rubbers (SMR 10 and SMR 20) were found to be suitable for manufacturing value-added rubber products. DTC samples with polymer contents of <40% and lower in curativescould still be considered for recycling, by adding higher portions of virgin rubber for manufacturing products like shoe soles, carpet underlay and thermoplastic elastomer products. Glove manufactures should ideally set up on-site DTC processing facilities at their factory premises equipped with crepers as well as space to ‘air dry’ the creped DTC samples. Creped samples could be sent to the Malaysian Rubber Board (MRB) for chemical analyses. Factory owners could also present the analytical results from MRB to the recyclers to obtain a good premium for their processed DTC samples to be used as raw materials.

Short Communication: Sulphur Levels And Fuel Quality In Peninsular Malaysia, Ramalingam M., Fuad A. Ahmad
ASEAN Journal on Science and Technology for Development
This paper presents the investigation on sulphur levels in fuels collected from different petrol stations in Peninsular Malaysia. Diesel and gasoline samples were analysed for sulphur using X-ray fluorescence spectrometry technique. In general, diesel concentrations of sulphur were only slightly lower than the Deprtment of Environment’s current sulphur limit of 500 p.p.m. across 2010–2014 (the range was 289–698 p.p.m., 374–410 p.p.m., 319–436 p.p.m., 447–605 p.p.m. and 300–477 p.p.m. for 2010, 2011, 2012, 2013 and 2014, respectively). Sulphur concentrations were relatively low in gasoline samples: the mean figures were 95, 77, 96, 74, 240 and 125 for 2009, 2010, 2011, 2012, …

Periphytic Diatoms In The Polluted Linggi (Sensu Stricto) And Kundor Rivers, Negeri Sembilan, Malaysia, Khan I.S.A. Nather
ASEAN Journal on Science and Technology for Development
The investigation in this paper aimed to describe periphytic diatom assemblage, species composition and distribution in tropical polluted Linggi (sensu stricto or s.s.) and Kundor rivers in Negeri Sembilan, Malaysia. Regardless of ecological and environmental conditions, diatoms were the numerically dominant flora among periphytic algae collected monthly over a period of 13 months at nine stations in the Linggi (s.s.) and Kundor rivers. The freshwater periphytic diatom samples were collected mainly using artificial substrates and supplemented with natural substrates. The periphytic diatoms thus collected from both natural and artificial substrates comprised 86 taxa (82 pennate and 4 centric forms) belonging …

ASEAN Journal on Science and Technology for Development
In this work, we computationally investigated from quantum chemical calculations (DFT) at the BP86 level with the various basis sets def2-SVP, def2-TZVPP, and TZ2P+, chemical bonding issues of the recently described carbene-analogues gold(I) complexes AuCl-NHEMe (Au1-NHE) with E = C – Pb. The optimized structures and the metal-ligand bond dissociation energy (BDE) were calculated, and the nature of the E→Au bond was studied with charge and energy decomposition methods. The equilibrium structures of the system showed that there were major differences in the bonded orientation from the ligands NHC-NHPb to gold(I) complex between the lighter and the heavier homologues.

ASEAN Journal on Science and Technology for Development
A team of healthcare professionals in the Department of Emergency and Medical Services demonstrated decision-making processes for a poisoned pediatric patient with a Do-not-resuscitate (DNR) order. At the same time, clinical guidelines for poison resuscitations were critically applied. Lastly, the case examined and evaluated emergency care, management, treatment and diagnostic laboratory tests for pediatric poisoned patients. Ideas on pertinent literatures of decision-making models, clinical guidelines on poison resuscitation and DNR policies were already known by the majority. In addition, ideas on the benefits such as becoming enlightened on how to make sound judgments in an emergency situation, particularly addressing issues …

ASEAN Journal on Science and Technology for Development
The changes in the global environmental conditions have placed great challenges on governments, industries, and societies. Business organizations are often blamed for being the sources of theseenvironmental problems. This study aimed to examine the factors influencing the perceived environmental performance of firms certified under the ISO 14001 in Malaysia. A total of 268 manufacturing companies responded to the questionnaires. In this study, structural equation modeling was applied to test the hypotheses. It was found that the “environmental policy”, “environmental training”, “regulatory stakeholder’s pressures”, and “customer pressures”, influence the firm’s perceived environmental performance in which “customer pressures”, was found to be …

ASEAN Journal on Science and Technology for Development
In this study, the photochemical degradation via photo-Fenton process was carried out to degrade dyes in textile industrial wastewaters. Experimental design methodology was also applied for optimizing effects of factors which influencethe effective treatment such as ferric dose, hydroperoxide dosage, initial pH, reaction time and initial chemical oxygen demand (COD). Two independent variables namely colour and COD removal efficiencieswere used to evaluate the treatment yield. Under the optimal conditions, ca. 99% and ca. 88%, colour, and COD were removed, respectively.
