Basma Foad,Salwa H. Abdel-Latif,TOSHIKAZU TAKEDA 한국원자력학회 2018 Nuclear Engineering and Technology Vol.50 No.8

In this work, the reactor kinetics capability is used to compute the design safety parameters in a PWR dueto complete loss of coolant flow during protected and unprotected accidents. A thermal-hydraulic codecoupled with a point reactor kinetic model are used for these calculations; where kinetics parametershave been developed from the neutronic SRAC code to provide inputs to RELAP5-3D code to calculateparameters related to safety and guarantee that they meet the regulatory requirements. In RELAP5-3Dthe reactivity feedback is computed by both separable and tabular models. The results show theimportance of the reactivity feedback on calculating the power which is the key parameter that controlsthe clad and fuel temperatures to maintain them below their melting point and therefore prevent coremelt. In addition, extending modeling capability from separable to tabular model has nonremarkableinfluence on calculated safety parameters

To fulfil the ever-growing demand for durable and multi-resistant textile fabrics against pathogenic bacteria, thiswork is aim to investigate the dual effect of coating cotton/polyester fabrics by composite of antibiotics/metal oxidenanoparticles. To carry out this study, cotton/polyester blended fabrics with different constructions were coated withZnONPs, ZrO2NPs, antibiotics namely doxymycin, cefadroxil, and ciprofloxacin (1 % w/v) individually and combined inpresence of citric acid and sodium hypophosphite as a crosslinking agent and a catalyst respectively. Nitrogen content (%N),metal content, and antibacterial activity as well as performance and physical properties were assessed. Full characterizationof untreated and treated fabrics by FTIR, SEM and EDX analysis were also carried out to confirm the binding and fixation ofthe used antibiotics and/or MONPs onto/within the fabric structure. The results revealed that the coated fabric samples byantibiotic/MONPs exhibited high nitrogen and metal contents as well as excellent antibacterial activity compared to thecoated fabrics by the nominated MONPs and antibiotics individually. The results also showed that the variation in theantibacterial functionality, performance and physical properties of the treated fabrics are governed by the type of substrate,type of construction and type of additives. Additionally, coated fabrics evinced satisfactory antibacterial efficacy even after15 washing cycles.

Various antiepileptic drugs (AEDs) especially enzyme-inducing AEDs might be associated withincreased vascular risk, through impairment of the endogenous antioxidative ability which may triggeroxygen-dependent tissue injury. Lamotrigine (LTG) a non-enzyme-inducing AED has scarce informationregarding its effects on oxidative stress. The present study aimed to study the possible modulationof vascular risk factors of epileptogenesis by LTG, in a rat model of kindling seizure induced bypentylenetetrazole (PTZ). Four groups of male Wister rats were used; vehicle control group, PTZ group(alternate day PTZ, 30 mg/kg, i.p), LTG/PTZ group (LTG 20 mg/kg/day p.o and alternate day PTZ)and LTG group. The study period was 5 weeks. Lipoproteins and total homocysteine (tHcy), malondialdehyde(MDA) and reduced glutathione (GSH) were measured. Aortic endothelial function studyand histopathological examination of the rats’ brains, aortas and coronaries were conducted. Serumtotal cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C), tHcy, MDA,GSH levels were significantly higher in epileptic rats than normal controls rats. A decrease inHDL-cholesterol with high atherosclerotic index was also demonstrated. The administration of LTGimproved the PTZ-kindled seizures. It produced a significant decrease in TC, TG and LDL-cholesterol,MDA, aortic GSH and increase in HDL-cholesterol with no significant effect on serum GSH and tHcylevels. LTG improved endothelium-dependent relaxation, decreased hippocampal neurodegenerativechanges and atherosclerotic changes of aortas and coronaries. LTG decreased seizures severity,hippocampal damage and improved vascular risk markers in this rat model of kindling seizures.

Basma Chlaihani,이연우 한국유아교육학회 2022 INTERNATIONAL JOURNAL OF EARLY CHILDHOOD EDUCATION Vol.28 No.2

This study used topic modeling, more specifically, the Latent Dirichlet Allocation (LDA) technique to analyse the trends found in scholarly research on literature-based instruction (LBI) in the area of early childhood education in the last twenty-two years (i.e., 2000 to 2021). A total of 150 papers published in 73 peer-reviewed journals met the selection criteria. Six topics were identified as the general topics dealt with by most of the papers. They were ‘arts and crafts,’ ‘types of reading and development,’ ‘inclusive education,’ ‘science, technology, and mathematics,’ ‘socio-emotional development,’ and ‘language.’ The results implied that the trend of research on LBI in the last 22 years has shown that it is an independent field, worthy of the attention of different scholars in different parts of the world. The trend of research also suggested that future studies in the field are needed with regard to specific topics and some specific contexts.

Autism spectrum disorder (ASD) is a developmental disorder associated with cognitive and neurobehavioral disorders. It affects the person’s behavior and performance. Autism affects verbal and non-verbal communication in social interactions. Early screening and diagnosis of ASD are essential and helpful for early educational planning and treatment, the provision of family support, and for providing appropriate medical support for the child on time. Thus, developing automated methods for diagnosing ASD is becoming an essential need. Herein, we investigate using various machine learning methods to build predictive models for diagnosing ASD in children using facial images. To achieve this, we used an autistic children dataset containing 2936 facial images of children with autism and typical children. In application, we used classical machine learning methods, such as support vector machine and random forest. In addition to using deep-learning methods, we used a state-of-the-art method, that is, automated machine learning (AutoML). We compared the results obtained from the existing techniques. Consequently, we obtained that AutoML achieved the highest performance of approximately 96% accuracy via the Hyperpot and tree-based pipeline optimization tool optimization. Furthermore, AutoML methods enabled us to easily find the best parameter settings without any human efforts for feature engineering.
