Nguyen, Thanh-Hoa Dang-Thi","doi":"10.21833/ijaas.2023.08.001","DOIUrl":"https://doi.org/10.21833/ijaas.2023.08.001","url":null,"abstract":"This research investigates the properties and modification of water caltrop starch (WCS) with a particular focus on its potential for retrogradation and resistance to enzymatic hydrolysis. The study begins by obtaining WCS with a recovery efficiency of 4.5% (w/w in dry basis). The native WCS exhibits notable characteristics, including an apparent amylose content of 45.4%, a ratio of amorphous/α-helix regions at 1.341, a degree of relative crystallinity of 54.43%, an average molecular weight of 6.58×104 g/mole, and a degree of polymerization of 365.57. The high amylose content and degree of crystallinity in native WCS indicate its favorable retrogradation potential and resistance to enzymatic hydrolysis. Textural analysis of the WCS gel reveals high hardness and chewiness but low adhesiveness, which further supports its potential for retrogradation applications. To explore the effects of repeated retrogradation cycles, native WCS was subjected to 3, 6, and 9 cycles. The increase in retrogradation cycles led to a decrease in apparent amylose content from 31.79% to 29.34%. This reduction can be attributed to the formation of double helix associations and the emergence of new crystalline regions from amylose molecules. Furthermore, an increase in retrogradation cycles resulted in enhanced syneresis of starch. Interestingly, as the number of retrogradation cycles increased, the enzymatic hydrolysis rate of retrograded WCS gradually decreased. Correspondingly, the estimated glycemic index (GI) of the samples decreased, reaching a range of 50.05 to 38.46. Consequently, treatment with repeated retrogradation proves to be an effective strategy for producing modified WCS with a low glycemic index (<50%), thereby presenting promising opportunities for low glycemic index applications.","PeriodicalId":46663,"journal":{"name":"International Journal of Advanced and Applied Sciences","volume":"86 5","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72387075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selected regression algorithms were implemented within the Waikato Environment for Knowledge Analysis. The assessment of their performance was conducted through the analysis of correlation coefficients, providing insights into their predictive capabilities. Notably, the Random Forest algorithm demonstrated the highest predictive power with an impressive correlation coefficient (r=0.76), surpassing other models in the analysis. Following Random Forest, the k-nearest neighbor algorithm achieved a substantial correlation coefficient of (r=0.65), followed by the Decision Tree (r=0.53), Linear regression (r=0.51), and the Multi-layer perceptron (r=0.51). In contrast, the Support Vector Machine showed a notably lower correlation coefficient (r=0.51), indicating its comparatively weaker predictive performance. Furthermore, this study uncovered two variables, \"Easy to Wash\" and \"Water Resistance,\" which displayed significant correlations of (r=0.49) and (r=-0.35), respectively, in relation to the predictive performance of the regression model. However, no significant correlation was observed for other variables. In light of these findings, future research endeavors may explore alternative predictive models to further assess and compare their performance against the outcomes presented in this study, contributing to the ongoing enhancement of slipper quality prediction methodologies.","PeriodicalId":46663,"journal":{"name":"International Journal of Advanced and Applied Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85292579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Empirical evidence substantiates that neonatal brain MRI surpasses both neonatal brain CT and ultrasound in diagnostic effectiveness. The underpinning rationale for this phenomenon lies in the heightened accuracy inherent to neonatal brain MRI procedures. To unravel the intricacies associated with disparities between neonatal and adult brain MRI procedures, the study meticulously investigates structural, shape, and size distinctions. This endeavor underscores the necessity for bespoke MRI apparatuses designed to account for these nuances. In pursuit of this objective, the integration of technologically advanced components such as compact scanners and refinements in magnetic and coil technologies has engendered tangible improvements. This innovation confluence bears testimony to the augmentation of patient safety, conferring a cascade effect wherein the precision of acquired MRI data underwrites accurate diagnoses and consequent therapeutic interventions.

Vaccine hesitancy, influenced by various vaccine-related factors, significantly impacts the adoption of COVID-19 vaccination. Misinformation contributes to vaccine distrust and hinders individuals' willingness to receive the vaccine. Despite its critical importance, there remains a paucity of comprehensive studies focusing on the determinants of vaccine confidence, leading to a deficiency in implementation research aimed at understanding and modifying individuals' behavior towards COVID-19 vaccination. This research endeavors to examine the influence of three key dimensions of trust in the COVID-19 vaccine, namely vaccine reliability, transparency in information dissemination, and pharmaceutical laboratory investment in innovation, on individuals' intention to receive the vaccine. Furthermore, we investigate the repercussions of these dimensions on actual COVID-19 vaccination behavior. Our quantitative study comprises a sample of 240 participants and employs a rigorous analytical approach. The findings underscore that individuals' intent to vaccinate against COVID-19 is positively affected by all three trust dimensions, i.e., drug reliability, innovation investment, and information transparency. Importantly, this intention positively correlates with actual vaccination behavior. This study substantiates the utility of the behavioral approach and the Theory of Planned Behavior (TPB) in elucidating vaccine hesitancy and the factors exerting influence on vaccine uptake.","PeriodicalId":46663,"journal":{"name":"International Journal of Advanced and Applied Sciences","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134997286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the escalated integration of DG systems has given rise to the predicament of reverse power flow, instigating elevated system power losses and voltage profile distortions. Thus, an imperative emerges to judiciously apportion and dimension DG systems, complemented by the incorporation of battery energy storage (BES) systems, as a remedial measure against these challenges. In this scholarly work, we present an innovative approach rooted in a precise energy management strategy (EMS) aimed at the adept allocation and capacity optimization of (PVDG-BES) systems. The study employs a two-step optimization methodology, the former facet of which expounds on the influence of BES system integration on grid power losses and voltage profiles during stable operational conditions. Subsequently, a pioneering optimization technique is formulated in the latter facet to identify the optimal siting and capacity allocation of the aforementioned system based on an optimal EMS framework. The primary focal point of this investigation is the minimization of total power losses. Validation of our proposition is conducted on the IEEE 14-bus standard system, incorporating the particle swarm optimization (PSO) algorithm. Simulation outcomes incontrovertibly affirm the efficacy and robustness of the proposed EMS, yielding substantive reductions in power losses and noteworthy enhancements in voltage profile integrity. Notably, the implementation of EMS leads to a remarkable 31% reduction in total power losses as compared to the initial scenario, prior to the amalgamation of PVDG-BES components. In sum, this study epitomizes a comprehensive strategy for fortifying power grid efficiency by orchestrating the symbiotic interplay of distribution generators and battery energy storage systems through an adept energy management paradigm.","PeriodicalId":46663,"journal":{"name":"International Journal of Advanced and Applied Sciences","volume":"2 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84025498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
