Research ArticleOpen accessIn the abstractVisual-Spatial Attention Abilities Among School Children Exposed to Low Environmental Lead LevelSana Maidoumi, Mariam Ouisselsat, Charif Radouan Ouaziz et al.Lead (Pb) is an intrusive toxic matter which harms the neuro-cognitive and behavioral development of children even with doses considered normal. The present paper aims at evaluating the visual-spatial attention function among 142 schoolchildren living in a mining area (cases) in comparison to 177 living in the Chouiter area (control group) in Marrakech. We used the Bell Dam Test (BDT) … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 12 Oct 2022 · 5,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Control Strategy for Parallel Fan-Powered VAV SystemsNabil Nassif, Iffat Ridwana, Mostafa Tahmasebi, Pejman EbrahimiASHRAE Guideline 36 recommends resetting the Supply Air Temperature (SAT) for Variable Air Volume (VAV) systems to balance fan power, heating and cooling loads and zone reheat requirements. This is achieved by employing a trim and response algorithm in conjunction with using the outside air temperature and readings from zone cooling loops. However, resetting the SAT for the VAV systems … …Energy Research Journal, Vol. 13, Issue 1 · 6 Jun 2022 · 10,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Identification of Leishmania Species in Patient with Cutaneous Leishmaniasis in an Endemic Area of Fars Province, Southern IranVahid Rahmanian, Nader Sharifi, Zahra Kargar Jahromi et al.The Cutaneous Leishmaniasis (CL) contains a range of factors, which provide different patterns of transmission that make it difficult to control. The aim of this study was to identify the different species of Leishmania in the Jahrom district of Fars province, southern Iran. This descriptive study was done on CL suspected cases who were referential to the Reference of Jahrom … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 2 Apr 2021 · 6,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hybrid Approach to Process Planning: The Urban Traffic Controller ExampleJimoh Falilat Olaitan, Simon Parkinson, Thomas Leo McCluskeyAutomated planning and scheduling are increasingly utilised in solving evsery day planning task. Planning in domains with continuous numeric changes present certain limitations and tremendous challenges to advanced planning algorithms. There are many pertinent examples to the engineering community; however, a case study is provided through the urban traffic controller domain. This paper introduce a novel hybrid approach to state-space … …Journal of Computer Science, Vol. 13, Issue 8 · 23 Aug 2017 · 7,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaximizing Fungal Growth in State-of-the-Art Tray Solid-State Fermenter: Aeration Strategies Optimized for Enhanced PerformanceMusaalbakri Abdul Manan, Colin WebbThis study introduced a tray fermenter, featuring eight layers of squared perforated trays, specifically designed for solid-state fermentation applications. It is named the multi-layer squared tray solid-state fermenter. The fermenter employs two aeration strategies with varying air flow rates to optimize fungal growth. Firstly, sterilized moistened air at 8 L/min flows from the bottom through the perforated trays. Secondly, a … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 9 Apr 2024 · 6,453 accessesView PDFCite
InvestigationOpen accessIn the abstractThe Effect of Adding Zeolite in the Feed of Chickens Cobb 500Angel Roberto Sánchez Quinche, Faviola Margarita Pindo Nagua, Oliverio Napoleón Vargas González et al.The objective of this study was to evaluate the effects of the addition of zeolite on the feeding of Cobb 500 chickens in the productive parameters. The work was carried out in an integral farm of Ecuador, adopting the standards of biosafety and animal welfare for the breeding of poultry; no vaccines or drugs were administered. 200 chickens (1-day old) … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 3 · 25 Sep 2017 · 8,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Rainfall Characteristics for Monitoring of the Extreme Rainfall Event in Makassar CityWahidah Sanusi, Usman Mulbar, Hendra Jaya et al.Flooding is a common problem that occurs in some regions of Indonesia, including Makassar city. In the planning of flood control, rainfall variables are very necessary as the frequency, intensity and duration of rainfall. The relationship of these variables can be expressed in a curve Intensity-Duration-Frequency (IDF). The objectives of this study are to identify the best fitting distribution of … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 10 Apr 2017 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoft Sensor Modeling of Product Concentration in Glutamate Fermentation using Gaussian Process RegressionRongjian Zheng, Feng PanThe on-line control of glutamate fermentation process is difficult, owing to the typical uncertainties of biochemical process and the lack of suitable on-line sensors for primary process variables. A prediction model based on Gaussian Process Regression (GPR) is presented to predict glutamate concentration online. First, Partial Least Squares (PLS) is applied to extract the features of the input secondary variables … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 17 Sep 2016 · 7,663 accessesView PDFCite
