We present a detailed study of the massive star-forming region G35.2-0.74N with Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm multi-configuration observations. At 0.″2 (440 au) resolution, the continuum emission reveals several dense cores along a filamentary structure, consistent with previous ALMA 0.85 mm observations. At 0.″03 (66 au) resolution, we detect 22 compact sources, most of which are associated with the filament. Four of the sources are associated with compact centimeter continuum emission, and two of these are associated with H30α recombination line emission. The H30α line kinematics shows the ordered motion of the ionized gas, consistent with disk rotation and/or outflow expansion. We construct models of photoionized regions to simultaneously fit the multiwavelength free–free fluxes and the H30α total fluxes. The derived properties suggest the presence of at least three massive young stars with nascent hypercompact H
ii
regions. Two of these ionized regions are surrounded by a large rotating structure that feeds two individual disks, revealed by dense gas tracers, such as SO2, H2CO, and CH3OH. In particular, the SO2 emission highlights two spiral structures in one of the disks and probes the faster-rotating inner disks. The 12CO emission from the general region reveals a complex outflow structure, with at least four outflows identified. The remaining 18 compact sources are expected to be associated with lower-mass protostars forming in the vicinity of the massive stars. We find potential evidence for disk disruption due to dynamic interactions in the inner region of this protocluster. The spatial distribution of the sources suggests a smooth overall radial density gradient without subclustering, but with tentative evidence of primordial mass segregation.

Introduction: Diseases such as diabetes mellitus may be associated with adverse changes in body composition. Sarcopenia is characterized by a progressive and generalized loss of skeletal muscle mass and functionality.

Aim: To investigate the relationship between type 2 diabetes mellitus (T2DM) and sarcopenia.

Materials and methods: In a retrospective, non-randomized study, 35 T2DM patients, aged 20-80 years, were assessed for sarcopenia prevalence compared to controls (n=16). Appendicular skeletal mass (ASM) (kg) was measured, and sarcopenia was defined as SMI <7.0 and <5.7 kg/m2, in males and females, respectively, using the European Working Group on Sarcopenia in Elderly (EWGOSP) definition. Low physical performance was defined as a walking speed of <0.8 m/s.

Results: Incidence of sarcopenia was significantly higher in T2DM patients vs. controls (27% vs. 20%, p=0.01) and elderly vs. young participants (40% vs. 12%, p<0.001), respectively. Walking velocity was significantly lower in T2DM patients compared to male and female controls (1.08±0.22 vs. 1.23±0.18 and 1.07±0.26 vs. 1.26±0.16, respectively, p<0.001,).

Conclusions: A moderate prevalence of sarcopenia in patients with type 2 diabetes mellitus was observed, which appeared to increase significantly in older men. Finally, incidence of T2DM displayed decreased physical performance in both genders.
Cutaneous manifestations of aortoiliac occlusive disease: two cases and review of the literature
Authors: Dourmishev Lyubomir , Nikolova Kremena , Miteva Lyubka
Published: August 2022

Aortoiliac occlusive disease (AIOD) is non-inflammatory obstructive vasculopathy commonly affecting patients with advanced atherosclerosis, diabetes mellitus, or elevated cholesterol levels, and subjects with other risk factors such as cigarette smoking.

Two Caucasian patients (a 55-year-old woman and a 56-year-old man), with ulcerous cutaneous lesions of AIOD are reported. In both cases, medical history comprises initial lower limb claudication, multiple painful ulcers along the legs and absence of superficial femoral artery pulse. Severe obstruction of both infrarenal aorta and iliac arteries on the left side was demonstrated by contrast angiography and Doppler ultrasonography.

The evolution of the disease showed some characteristic findings, including pyoderma gangrenosum-like ulcerations as the initial cutaneous manifestation of AIOD, multiple painful ulcers along the lower extremities, and aorto-iliac occlusive disease due to atherosclerosis.

Early diagnosis and surgical reconstruction of vessels in patients with AIOD improved quality of life and limb salvage rates.
Invasive round goby shows higher sensitivity to salinization than native European perch
Authors: Backström Tobias , Winkelmann Carola
Published: August 2022

Salinity is an influential abiotic environmental factor in aquatic species, specifically in freshwater, where salinization causes ecosystem degradation. Secondary salinization, that is increases in salinity due to anthropogenic activities, can affect both osmoregulation and behaviour in freshwater fishes. It is generally believed that invasive species handle climatic change and environmental degradation better than native species, which is one reason for their invasion success. However, how invasive and native species cope with salinity changes remains little understood. Therefore, we investigated how low (500 µS/cm) and high salinity (2000 µS/cm) conditions affected oxygen consumption and behaviour in the invasive round goby (Neogobius melanostomus) and the native European perch (Perca fluviatilis). Our results showed that in round goby oxygen consumption increased and swimming and non-swimming movements changed in response to salinity increments, whereas European perch was not affected by salinity. Thus, it seems as if the invasive round goby is more sensitive to changes in salinity than the native European perch. Our results fit with the minority of studies indicating invasive species being less tolerant than some native species to environmental changes. This finding could be explained by the adaptation of round goby to low salinity due to its long establishment in River Rhine. Further, our results are also confirming that the effect of salinity is species-specific. In addition, European perch and round goby show diametrically different behavioural response to disturbance which could be an effect of holding different ecological niches as well as their anatomical differences.

Accès à l’emploi et revenus parmi les sortants du système de formation technique et professionnelle en Haïti : résultats empiriques sur données transversales
Authors: Jacob Sergot
Published: August 2022

Nous avons examiné, d’une part, la probabilité, pour les sortants du système de formation technique et professionnelle (SFTP) haïtien, d’accéder à l’emploi dans les 10 départements géographiques du pays ; et, d’autre part, les déterminants des revenus encaissés. Pour ce faire, nous avons exploité des données transversales de différentes natures et sources : qualitatives (collectées auprès de 75 acteurs du SFTP et du système économique ; et de 27 responsables de centres de formation) ; et quantitatives (auprès des 27 centres ; et de 530 diplômés sur la période 2011-2016). Nous avons recouru à trois types d’analyse : qualitative, descriptive et économétrique. Les résultats mettent en évidence un faible taux d’accès des diplômés à l’emploi (34 %), ce qui suggère l’existence de distorsions majeures tant dans le système de formation que dans celui du marché du travail, et aussi l’inefficacité des actions gouvernementales dans ces domaines. À l’aide d’estimateurs Probit univariés et de fonctions de gains, l’analyse économétrique montre que ce sont surtout des actifs sociaux – c’est-à-dire les réseaux relationnels et familiaux – qui, en donnant un accès privilégié aux opportunités disponibles, permettent aux diplômés de s’insérer dans la vie active et de dégager des revenus également plus élevés. Le secteur de formation, l’année d’obtention du diplôme, ou le type de centre fréquenté sont aussi déterminants. Les autorités politiques ne devraient plus ignorer ces aspects tant est importante la nécessité de rendre les chances égales en aval du système de formation, entre les sexes et au niveau social.

Protéger l’enfant ou préserver la famille ?
Authors: Zappi Lola
Published: August 2022

Dans l’entre-deux-guerres, le tribunal pour enfants de la Seine s’adjoint l’aide d’un service social. Les assistantes du Service social de l’enfance (SSE) ont massivement recours au placement d’enfants. Pourtant, leur mission ne s’arrête pas là. Durant toute la durée du placement, elles cherchent à s’assurer que les parents restent en contact avec leurs enfants. Comment expliquer cet apparent paradoxe ? Grâce aux dossiers du SSE, l’article montre que les assistantes sociales sont prises en tenaille entre deux injonctions contradictoires : d’une part, la peur de l’influence du « milieu » familial sur les jeunes de milieux populaires ; d’autre part, la psychologisation croissante des liens affectifs parents/enfants. En croisant une histoire des savoirs et une histoire du travail, l’article explore les innovations infra-réglementaires mises en œuvre par les assistantes sociales, et invite à nuancer une lecture monolithique de la « police des familles ».
Faire « famille » ou faire « communauté »
Authors: Jusseaume Anne
Published: August 2022

Cet article interroge l’utilisation des mots de la parenté dans les discours et le quotidien de la vie religieuse, à partir d’une étude de cas sur les Filles de la Charité, des années 1840 à la fin des années 1930. Présentée comme une famille de substitution aux sœurs, la vie en communauté se modèle sur l’idéal familial pour qualifier ses membres, ordonner les relations du quotidien et créer une uniformité institutionnelle caractérisée par un esprit propre à sa famille religieuse. La parenté quotidienne des sœurs ne doit pourtant pas prendre la forme familière , telle qu’elle est perçue par l’institution religieuse. Bien que le discours familial permette de tenir ensemble les différentes dimensions qui organisent la vie collective dans l’institution, la vie communautaire se distingue de la vie familiale et doit témoigner d’une réalité autre. Non seulement la famille « naturelle » est mise à distance, mais les comportements quotidiens doivent aussi s’éloigner d’un modèle familial bourgeois qui valorise l’affection, nécessitant une formation renouvelée dans l’entre-deux-guerres.
Écrire la vie d’une famille en institution : le journal du couple Bachellery (Paris, 1835-1852)
Authors: Rogers Rebecca
Published: August 2022

Cet article questionne les interactions entre vie familiale et vie institutionnelle à partir d’une source exceptionnelle : un journal de famille tenu par un couple de pédagogues – Joséphine et Félix Bachellery – entre 1835 et 1852. Maîtresse de pensionnat réputée à Paris sous la monarchie de Juillet, Joséphine Bachellery est connue pour ses prises de position publiques en faveur d’un enseignement secondaire de filles. Le journal témoigne de la face privée de ses engagements et révèle en creux une histoire rarement abordée : ce que la famille fait à l’institution scolaire. En chroniquant la vie de famille, le journal ne peut éluder le cadre de leur vie domestique : un important pensionnat où la maîtresse de pension agit comme cheffe d’entreprise, enseignante et mère de famille. Un double questionnement sous-tend l’analyse proposée : celui de la place des liens familiaux dans le fonctionnement institutionnel et, dans un deuxième temps, la manière dont les exigences du pensionnat interviennent dans la vie familiale, mettant parfois à rude épreuve les liens affectifs entre parents et enfants.
Measuring digital economy in China
Authors: Xu Yanting , Li Tinghui
Published: August 2022

The COVID-19 pandemic has highlighted the importance of the digital economy in restoring economic and social development, creating more jobs and improving people's well-being. To inform policy makers about changes to digital strategies, measuring the digital economy is a prerequisite. This study aimed to compile an index of digital economy at the provincial (municipalities, autonomous regions, collectively referred to as "provinces") level to present an accurate and in-depth depiction of how it has developed in China. Our sample covers 31 provinces in China, over the period 2010–2020. This paper firstly constructs the digital economy index system from the four dimensions of digital users, digital platforms, digital industries and digital innovation, and then adopts a combination of entropy weighting method and grey target theory to measure the digital economy index. This paper study revealed that China's digital economy has been on an upward trend from 2010 to 2019 and has a decline in 2020, and the digital innovation is an important driving force for the growth of the digital economy index. The convergence of China's digital economy is decreasing, indicating that the gap in digital economy development between provinces is increasing. The proposed index in this study can be used as a screening tool, decision making tool, benchmarking tool and guidance of high-quality digital economy development.

Published: August 2022

The calcification of ligamentum arteriosum occurs after the normal closure of the ductus arteriosus. Foreign body ingestion is a common event in the pediatric age, and it is frequently addressed in the Emergency Room. We report a case of foreign body in a patient with unknown calcification of the ligamentum arteriosum. His parents noted blood in the saliva, but he had no symptoms indicative of an acute clinical situation. The CT showed a hyperdense object in the aorto-pulmonary window with features compatible with a metallic object. The child underwent surgery, during which a calcified ligamentum arteriosum was found and no foreign body. This phenomenon has been described to be better identified using multi-section CT scans than X-Rays.

Published: August 2022

Big data learning analytics is still in its infancy and has been developed on several campuses worldwide. Ideally, all students' profiles should be described and embraced to optimize the development of any proposed system related to big data learning analytics. This paper aims to extract information related to factors contributing to students’ academic achievement using quantitative and qualitative approach, in which co-occurrence analysis were applied for quantitative approach and facet analysis for the qualitative approach. For data collection, Kitchenham’s technique were used to select and filter the literature, at the first iteration, 1,167 papers were found. After applying inclusion and exclusion criteria, 101 articles were processed for text mining. Titles and abstracts were analyzed using a text-mining tool, and then resulted clusters of words. Afterwards, clusters of words were labeled using facet analysis. This study results in eight interrelated clusters of academic achievement factors: demography, internal consistency, technology, student course engagement, activity in a classroom, educational system, socio-culture, and personality. Several insights into each cluster will be described and might be beneficial for researchers in learning analytics.

Requirement Analysis of Student Individual Learning Based on the Idea of Lifelong Learning
Authors: Wang Huimin , Zhang Wei
Published: August 2022

We are currently experiencing a knowledge-chasing society in which acquiring new knowledge and solving new problems are necessary and required skills for people to survive in human society in the future. Therefore, in such a circumstance, it is of certain research value to analyze the requirement satisfaction of Student Individual Learning (SIL) based on the idea of lifelong learning and discover problems in the process of SIL. However, existing studies generally have a few shortcomings such as the too narrow scope of study groups and the undiversified research objects. To this end, this paper took English learning as an example to research the requirement analysis of SIL based on the idea of lifelong learning. In the texts, the paper constructed a requirement satisfaction (RS) model of SIL, gave the calculation method of the learning benefit of SIL, and elaborated on the strategy optimization and selection method of SIL. The effectiveness of the proposed model was verified by experimental results attained in the study.
Impact of Internet Self-Efficacy and Self-Regulated Learning on Satisfaction and Academic Achievement in Online Learning: A Case Study in Vietnam
Authors: Dinh Tuong Cao , Nguyen Phuong Bao Ngoc
Published: August 2022

The unexpected prolonged expansion of the Covid-19 pandemic has urged nu-merous educational institutions worldwide, including Vietnam, to offer online courses. Identifying factors that impact student satisfaction and academic achievement, hence, becomes crucial in online learning environments. The current study examines the impact of students' self-regulated learning and Internet self-efficacy on these two learning outcomes in an online environment. The proposed research model consists of two exogenous variables including students' Internet self-efficacy and self-regulated learning, and two endogenous variables, namely students' satisfaction and academic achievement. 710 students from four universi-ties in Vietnam voluntarily participated in this study by completing an online sur-vey questionnaire. The data analysis was performed by Partial Least Square Structural Equation Modeling (PLS-SEM). The results indicated that Internet self-efficacy, goal setting, and help-seeking have direct positive effects on both student satisfaction and academic achievement. Self-evaluation positively affected student satisfaction while it did not have an impact on student academic achieve-ment. Elaboration, environment structuring, and task strategies did not have a sta-tistically significant relationship with student satisfaction as well as their academic achievement. Students' satisfaction has a direct positive impact on their academic achievement. Pedagogical implications and limitations of the study are also deduced.

ViCT or spelled "VISIT", is the name of a web-based application that is being developed to display various points and locations from the campus environment that can be accessed virtually. ViCT aims to help users, students, and the public explore campus with digital freedom of movement anytime and anywhere, educating users about campus facilities and services with an immersive technology experience that is eco-friendly and fun. The application development concept is unlimited visits and easily accessible via desktop and mobile, saving resources and costs. In this chapter, the focus of the researchers discusses the initial digital mapping of the campus environment, which is the object or study area of the development of virtual campus applications with 360-degree panoramic image techniques. Spherical panorama images are the primary basis of the virtual reality environment in this application. Each panoramic image is processed and merged into a unified whole on a web page. Spherical panorama photos captured using ultra-wide-angle lenses at the front and rear of the camera (dual fisheye) generate a visual field with a horizontal and vertical angle of view close to 360 degrees.
André Gide & Marcel Proust
Authors: Masson Pierre
Published: August 2022

Le 21 novembre 1912, le manuscrit de Marcel Proust, alors connu sous le nom du Temps perdu, est rejeté par La Nouvelle Revue française. Cette décision, dont André Gide endossera la responsabilité, est à l’origine d’une solide réputation d’inimitié entre les deux hommes.

Mais limiter à cette anecdote la relation entre les deux écrivains, c’est méconnaître tout ce que leur correspondance nous enseigne : « Le refus de ce livre restera la plus grave erreur de la N.R.F., et [...] l’un des regrets, des remords, les plus cuisants de ma vie. » Cet aveu de Gide, dans un courrier adressé à Proust plus d’un an après le rejet de son manuscrit, inaugure un dialogue qui se poursuivra jusqu’à la mort de ce dernier. Un dialogue complexe, parfois marqué par des désaccords profonds. Car si leur culte de l’art et leur désir d’affirmer leur sexualité auraient pu les rapprocher, leur vision de la littérature était opposée, et le trop explicite Proust allait devenir suspect aux yeux de Gide, à l’engagement plus raisonné.

C’est l’histoire de cet échange, tantôt passionné, tantôt distant, que Pierre Masson, l’un des plus grands spécialistes d’André Gide, reconstitue dans cet ouvrage.
André Gide & Jef Last
Authors: Gide André , Last Jef
Published: August 2022

André Gide, frais converti au communisme, et le jeune militant enthousiaste Jef Last se lièrent d’amitié en 1934, à l’occasion d’un grand meeting parisien. Dès le printemps suivant, ils voyageaient ensemble au Maroc ; en 1936, Last accompagne Gide en URSS... En 1947, il est encore à ses côtés aux Fêtes de la Jeunesse à Munich. Jusqu’à sa mort, Gide échangea une abondante correspondance avec « ce fou de Jef » (1898-1972), romancier et journaliste hollandais, polyglotte, grand voyageur et personnage pittoresque et haut en couleurs, l’« ami charmant » pour qui il avait éprouvé « cette sorte de sympathie subite et violente, qui bondit par-dessus les barrières factices ». Les quelque 180 lettres inédites publiées ici prennent place au côté des grandes correspondances gidiennes déjà connues, et sont particulièrement intéressantes pour comprendre la « politique » de Gide (le voyage en URSS, la guerre d’Espagne, Munich...), mais il y est aussi beaucoup question de littérature, de voyages – et d’amitié.
André Gide & Edmond Jaloux
Authors: Gide André , Jaloux Edmond
Published: August 2022

Le jeudi 23 avril 1896, dans sa chambre de la rue des Tonneliers à Marseille, un jeune poète de 18 ans, qui vient de faire paraître à compte d’auteur un recueil de vers symbolistes, reçoit la visite inattendue d’André Gide, de huit ans son aîné. Entre Edmond Jaloux et l’auteur de Paludes et du Voyage d’Urien dont il lit les œuvres à la manière d’un bréviaire où pulser un sens à sa vie et à son engagement littéraire, c’est le début d’une longue amitié qui, sans être ni pour l’un ni pour l’autre de premier plan, durera avec ses cimes et ses creux jusqu’à la fin de leurs jours. La correspondance, inaugurée par cette première rencontre, constitue d’abord pour le plus jeune une véritable initiation morale et intellectuelle, jalonnée par ses lectures renouvelées des œuvres de l’aîné – le « Récit de Ménalque », Les Nourritures terrestres et L’Immoraliste qu’il est l’un des premiers à comprendre - puis par l’écriture de ses premiers textes en prose qu’il soumet tremblant à son maître, enfin par l’attente fiévreuse de ses visites qu’il souhaiterait toujours plus fréquentes.Cette amitié passionnée de l’apprenti poète pour l’écrivain déjà reconnu par une élite pourrait sembler disproportionnée, mais Gide, qui ressent une vive sympathie pour l’enthousiasme de ce néophyte, éprouve auprès de lui la force de l’influence en littérature en l’aidant à se découvrir romancier. Ces lettres, inédites pour l’essentiel, découvrent ainsi les débuts d’une aventure intellectuelle et montrent que l’éducation d’un esprit ne consiste pas à le faire pareil à soi, mais à développer sa profonde singularité, son « idiosyncrasie » aurait dit Gide. Elles redonnent aussi vie à Edmond Jaloux, que son œuvre abondante, injustement oubliée, porta à l’Académie et dont le magistère, exercé notamment aux Nouvelles littéraires, fit de lui le critique le plus redouté de son temps.
André Gide & Eugène Rouart 1
Authors: Gide André , Rouart Eugène
Published: August 2022

On ne peut tout à fait comprendre l’œuvre et la vie d’André Gide sans y marquer la place essentielle tenue par son amitié avec Eugène Rouart. De 1893 à 1936, les liens entre les deux hommes, souvent tendus, parfois distants, restèrent affectueux, malgré les événements et les idées qui ont pu les troubler. Leur Correspondance, une des plus importantes et des plus révélatrices parmi celles que Gide entretint avec les plus notables de ses contemporains, aborde des domaines très divers : la littérature, bien sûr, mais également les beaux-arts, la sexualité, la politique, l’industrie et le commerce, les affaires, l’agriculture...Élevé dans un milieu de peintres, de musiciens, d’hommes politiques, d’industriels, Rouart offrait à Gide de nombreuses ouvertures dans le monde culturel de son époque. L’homosexualité rapprocha les deux amis. C’est dans ses lettres à Rouart que Gide conçut le projet d’écrire Corydon. Dédicataire de Paludes, Rouart écrivit un roman, La Villa sans maître, qui inspira L’Immoraliste où les chapitres sur l’activité agricole en particulier portent l’empreinte de cet homme dont Gide dira que sa vie était « la plus compliquée, la plus foisonnante et la plus dramatique » qu’il ait pu voir.Antidreyfusard fougueux en 1898, Rouart devint quelques années plus tard un pilier de la IIIe République - maire, conseiller général, chef de cabinet d’un ministre important, enfin sénateur. Captivé par le caractère hors norme de son ami, Gide se laissa entraîner par lui dans diverses entreprises commerciales que la publication de ces lettres éclaire pour la première fois. Elles fournissent aussi des précisions inédites sur la crise que le ménage Gide traversa en 1916-1918 et d’où naquit La Symphonie pastorale. L’intensité avec laquelle Rouart poursuivait ses ambitions, écartelé entre sa vie publique et ses désirs intimes, trouvait en Gide, constamment à l’affût d’expériences psychologiques hors du commun, un observateur attentif, toujours prompt à mettre à profit les aventures d’autrui : c’est ainsi que Rouart, au sommet de sa carrière, membre de l’Académie d’Agriculture et sénateur de la Haute-Garonne, sera le modèle du Robert de L’École des femmes.
Design of an Assistant Decision Support System for Sports Training Based on Association Rules
Authors: Zeng Zhiliang , Jiang Qianqiu
Published: August 2022

In order to quantitatively evaluate the effect of sports training, it is necessary to track the dynamic characteristics of sports by using sports training aided decision support system. When the existing sports training assistant decision support system extracts the features of decision association rules, some redundant features will appear when establishing the global association rules, which increases the amount and difficulty of data calculation and affects the effect of assistant decision support. On this basis, the data fusion of assistant decision support information is carried out, and the optimal assistant decision support scheme is obtained according to the fusion results. The experimental results show that the design system is superior to the existing auxiliary decision-making system in motion recognition rate, motion result accuracy rate, and decision-making accuracy rate, which can provide users with auxiliary decision-making support for sports training and has good practical application effect.

Published: August 2022

The human-computer interaction has been widely used in many fields, such intelligent prosthetic control, sports medicine, rehabilitation medicine, and clinical medicine. It has gradually become a research focus of social scientists. In the field of intelligent prosthesis, sEMG signal has become the most widely used control signal source because it is easy to obtain. The off-line sEMG control intelligent prosthesis needs to recognize the gestures to execute associated action. In order solve this issue, this paper adopts a CNN plus BiLSTM to automatically extract sEMG features and recognize the gestures. The CNN plus BiLSTM can overcome the drawbacks in the manual feature extraction methods. The experimental results show that the proposed gesture recognition framework can extract overall gesture features, which can improve the recognition rate.
A Distributed System-Based Multiplex Networks to Extract Texture Feature
Authors: Liu Yang , Yuan Weiqi
Published: August 2022

Defect detection is an indispensable part of quality detection in manufacturing. It is a challenging task to recognize defects on the surface of castings with random textures. This paper proposes a texture extraction method based on multiplex networks for defect segmentation in a random background. The proposed method redefines the image information in the form of multiplex network topologies according to the different properties of casting surface texture. Finally, the proposed method segments different texture regions by extracting the similarity of texture primitives in the multiplex networks. The study conducted experiments in a distributed system environment, and the results show that the proposed method is effective in actual industrial data sets. As an interdisciplinary application of network science and machine vision, the proposed method provides a valuable application mode for the development of complex networks in new fields and provides a new research idea for the texture analysis of castings.

Spinel ferrites nanoparticles have attracted the attention of researcher for memory storage devices. We have synthesized MgFeO4 pure sample and MgFe1.8Sm0.2O4 doped sample via solgel technique. The study of structural, electrical, dielectric, and I-V properties were studied of synthesized spinel magnesium ferrites nanoparticles. X-ray diffraction (XRD) confirmed the spinel structure of both compositions. The frequency dependent AC conductivity, dielectric constant, dielectric tangent loss, was studied in the range of 20Hz to 3MHz. I-V measurements has been done for the resistive switching properties. I-V curves of both compositions in the current study exhibits the formation of hysteresis loop. The hysteresis loop behavior shows that with the addition of samarium the trend of loop increases which plays crucial role as a Resistive Random-Access Memory (ReRAM) application in switching memory storage devices.

In this study, strain measurement can be analyzed in sub-10nm SiGe layer (~7 nm) grown on [100] Si substrate by chemical vapor deposition at the nanoscale level. The measurement technique is based on transmission electron microscopy (TEM), in which high-resolution transmission electron microscopy (HRTEM) image is combined with the image processing of geometric phase analysis (GPA) software. In this case, GPA analyzes the HRTEM images formed at the [011] zone axis to obtain information about strain maps along the [100] growth direction of the nanoscale SiGe region. The strain analyzed in the SiGe layer is within 1.6-2.9% with high precision and high spatial resolution.

Kapok fiber has been known for its hydrophobic-oleophilic characteristics and exhibits a great potential as oil sorbent. Methods in enhancing its hydrophobicity have been explored to improve its sorption performance in oil-in-water applications. This study investigates the oil sorption performance and hydrophobicity of kapok fibers coated with calcium stearate, a known waterproofing agent. The calcium stearate solution was prepared by mixing known amounts of stearic acid and calcium chloride in an ethanol solution. This was followed by hydrolysis using 0.12 M sodium hydroxide solution. The calcium stearate-coated kapok fibers exhibited higher hydrophobicity compared to raw kapok fibers with a water contact angle of ~137°. It achieved the highest oil sorption capacity and reusability of 50 g/g and 65% for viscous motor oil, respectively.

The development of variety printing methods and compatible conductive inks is to support the emerging high demand production of printed electronic devices. Conductive ink is used to create conductive paths as interconnecting tracks for the printed electronic devices. The method of integrating various conductive materials using thermoplastic viscous paste was introduced in order to enhance the ability of conductive ink to conducts electricity. Carbon nanomaterial’s offer many opportunities in the conductive ink application especially for printed and flexible electronics. This study aims to produce highly functional conductive ink using graphene nanoparticles (GNP) with Bisphenol-A (BPA) resins as a binder by investigate the mechanical properties and characterization of graphene nanoparticles conductive ink at of different patterns. The effect of nano-indentation, for straight line shape, curve shape, square shape and zigzag shape circuit printed on thermoplastic polyurethane (TPU) substrate were observed. The hardness and elastic modulus for the formulated graphene nanoparticles conductive ink shows that square patterns displayed a better mechanical properties compared to the other patterns. Scanning electron microscopy (SEM) and energy dispersive x-ray (EDX) finding also show that square pattern has a uniform distribution of (GNP) filler and lowest amount of atomic weight with fine granular particle indicating of lower resistance value which can contribute to have higher conductivity property. Overall obtained results showed that a square pattern produced good performance in term of mechanical properties that can enhance the conductivity of the conductive ink.

New bioactive materials were developed with claims of potential remineralization in the oral environment, particularly in acidic conditions. Direct bioactive restorative materials should resist mechanical load from mastication in saliva pH changes. However, the lack of evidence still exists on its bioactive ability to prevent demineralization. The purpose of this study was to evaluate the effects of cariogenic pH solution on acid buffer capacity and compressive strength of bioactive restorative materials. Thirty disc-shaped specimens of 5 commercial bioactive restorative materials were selected (diameter 15mm; thickness 1mm) and were immersed in 10ml of cariogenic pH solution (pH 4.7) at 37 ± 1°C. They were then evaluated for its buffer capacity using a pH meter every 30, 60, 90, 120, and 150 minutes respectively. Twelve specimens (diameter 4mm; height 6mm) of each material were immersed in a group of cariogenic pH solutions with pH 7 and 4.5 for 7 days. The compressive strength was tested using Universal Testing Machine and statistically analyzed by One-way ANOVA and Kruskal Wallis. The results showed an increase in pH of the cariogenic solution of all materials and an increasing immersion time. The compressive strength of Activa Bioactive Restorative had the lowest value after immersion in cariogenic solution pH 4.5. It can be concluded that bioactive restorative materials have a buffering capacity that can increase cariogenic pH solution towards neutral conditions within 150 minutes of immersion. Alkasite composite resin and Zirconomer Improved immersed for 7 days in cariogenic pH solution to stay stable at pH 4.5 and 7.

Pineapple wastes (skin, core and crown) are mainly composed of carbohydrates (cellulose, hemicellulose, and lignin). Non-starch polysaccharides (NSP) in feed are indigestible by the endogenous enzymes in poultry. Thus, exogenous enzymes (xylanase and cellulase) are required to overcome this problem. Due to high fiber content, pineapple wastes are unsuitable for animal feed. However, the fermented waste juice could be used to produce enzymes. The objective of this study is to produce xylanase and cellulase from the fermentation of pineapple waste using Lactobacillus casei (L. casei) bacteria inoculated from probiotic drink. The fermentation was performed using different screening parameters (incubation time, temperature, pH value and substrate concentration) according to Two-Level Full Factorial Design (FFD) by Design Expert. From this study, the incubation temperature and substrate concentration had the highest influence on the xylanase activity (39.82 U/mL) while the fermentation time and substrate concentration mostly affected the cellulase activity (8.05 U/mL). Meanwhile, the pH had the least influence on both enzyme activities. The pineapple waste at its best fermentation parameters not only offers an economical way of high enzyme production but also alleviates the agricultural waste disposal issue. Further optimization of the pineapple waste fermentation parameters is required though to maximize enzyme production.

The purpose of this study was to evaluate the effect of adding horn beetle nano chitosan (NCH) to Glass Ionomer Cement (GIC) liquid on surface roughness. The evaluation was done before and after the addition of NCH and from the length of time soaking in artificial saliva. The disc sample with a diameter of 6 mm and a height of 3 mm of total 40 samples were divided into four groups: the GIC control group, GIC modified NCH 0.5%, 1%, and 2%. Each sample was immersed for 24 hours and seven days in artificial saliva. Surface roughness before and after immersion was measured using the Surtronic S-100 Series Surface Roughness Tester. Data analysis was performed using a one-way ANOVA test to determine the effect of adding horn beetle NCH and paired t-test to determine the effect of immersion time on the surface roughness of GIC. Although the highest surface roughness values were found in sample GIC modified NCH 1% (2.51±0.86 for 24 hours) and in sample GIC modified NCH 2% (2.64±0.84 for 7 days), there was no significant differences for both the surface roughness with the addition of NCH (p > 0.05) and the length of immersed time (p > 0.05). As the conclusion, there is no effect of horn beetle nano chitosan to GIC surface roughness. However, the addition of horn beetle NCH presented rougher surfaces after immersion. These experiments can help predict the performance of these materials under clinical conditions.

Retracted article: In this study, the influence of silane coupling agent on the matrix/ fiber interface bonding and its effect to the mechanical properties of oil palm frond fiber reinforced polyester composites were investigated. Tensile and flexural properties of the composites were studied at 0 - 10.2 volume fraction (% fiber content). Results showed an increasing trend in tensile modulus while tensile strength and flexural strength reduced as the fiber content increased. Higher tensile modulus values were observed in silane treated fiber composites due to additional fiber/ matrix interaction and increment in polyester molecular chain mobility constraint. Reduction in tensile strength is caused by decrease in the matrix crystallinity and formation of stress concentration spots emerging from interface discontinuity. These obstructions, however, were reduced by fiber surface modification, which improved the tensile strength. Enhanced fiber dispersion upon surface modification was unveiled through scanning electron micrograph images.
