Large-Eddy Simulation of Low-Reynolds-Number Flow Around Partially Porous Airfoils
Authors: Li Jinyu , Nagata Koji , Watanabe Tomoaki
Published: July 2023

This paper uses the large-eddy simulation framework in OpenFOAM to investigate the flow characteristics around two-dimensional partially porous airfoils with symmetrical flat geometries, which were used in a previous experiment. The effects of a porous medium near the trailing edge are investigated at a chord Reynolds number of 350,000. Two porous media are modeled to investigate how the porous medium influences the flow around the airfoil and aerodynamic performance: One is a normal porous medium, defined as a homogeneous and isotropic material with identical properties in all directions. The other medium consists of straight holes perpendicular to the airfoil surface, allowing fluid to pass through unidirectionally. It is observed that drag and lift forces vary, depending on the internal structure of the porous medium. The size of the laminar separation bubbles also varies, depending on the parameters of the porous medium, such as the internal structure, the length of the porous section, and the porosity. It is shown that an airfoil with a low-porosity unidirectional porous medium increases the lift-to-drag ratio at high angles of attack as compared with the nonporous airfoil.
Bayesian Gappy Proper Orthogonal Decomposition for Aerodynamic Data Fusion
Authors: Bertram Anna , Bekemeyer Philipp , Held Matthias
Published: July 2023

During the development of an aircraft, a multitude of aerodynamic data are required for different flight conditions throughout the flight envelope. Nowadays, a large portion of these data are routinely acquired by computational fluid dynamics simulations. However, due to modeling and convergence issues especially for extreme flight conditions, numerical data cannot be reliably generated for the entire flight envelope yet. Hence, numerical data are complemented by data from wind tunnel experiments and flight testing. However, the data from these different sources will always show some discrepancies to deal with. Data fusion methods aim at combining the individual strengths and weaknesses of data from different sources in order to provide a consistent data set for the entire parameter domain. In this work we propose an extension to the well-established Gappy proper orthogonal decomposition technique by reformulating the least-squares problem as a regression task. A Bayesian perspective is imposed to account for uncertainties during the data fusion process. This involves a kernelized regression formulation that also addresses the problem of linearity imposed by the dimensionality reduction method and therefore adds more flexibility to the approach. The performance and robustness of the approach is demonstrated investigating an industrially relevant, large-scale aircraft test case fusing high-quality experimental and numerical data. Compared to the established Gappy POD approach, the new method shows a significantly improved agreement with the observed wind tunnel data for the investigated test case. In addition, the new approach enables to provide credible bounds for the fused result, which serve as an indicator for the associated uncertainty.
Forebody Articulation at High Angles of Incidence
Authors: Kumar Roopesh , Foster Devon S. , Kumar Rajan , Dickinson Benjamin T.
Published: July 2023

An experimental investigation was carried out to understand the effect of forebody articulation on the aerodynamic characteristics and the flowfield development over a slender body at high angles of incidence. The experiments were carried out at the Florida A&M University and Florida State University low-speed wind tunnel over a range of forebody deflection ([Formula: see text], [Formula: see text], and [Formula: see text]) and flow conditions. The results show that a positive forebody deflection increases the normal-force coefficient, whereas a negative forebody deflection decreases the normal-force coefficient at high angles of incidence. Pitching moment characteristics showed that all forebody deflections tested produce a pitching moment despite minimal normal force at low angles of incidence. Lateral aerodynamic characteristics showed that the side-force onset angle does not solely depend on the semi-apex angle of the forebody (as predicted for axisymmetric slender bodies), and the role of the forebody-to-aftbody transition geometry in initiating vortex asymmetry is equally important. The particle image velocimetry results show that a positive forebody deflection increases the size, strength, and circulation of the vortices developing on the body, leading to an increase in aerodynamic forces and moments. The flowfield development for a negative forebody deflection is dominated by secondary shear-layer vortices originating from the forebody to aftbody junction.
Fraseología y romancero: una mirada renovada
Authors:   Universitat de València (España), Echenique Elizondo María Teresa
Published: July 2023

«Romancero» and historical Phraseology are philological fields whose oral and written transmission intersect, with relevant outcomes. This article offers some reflections on the convenience of studying both fields concurrently, given that some phraseological units contained in Spanish ballads show historical, geographical and social significant variation that may contribute to their diachronic study; to this must be added the prospective benefits of applying the methodological principles of historical phraseology to the study of the «Romancero», as they could shed light on the process of oral and written transmission of Spanish ballads.
De las fórmulas notariales latinas a las romances en el siglo xiii. A propósito de la traducción en la fraseología histórica del español
Authors:   Universitat de València (España), García Valle Adela
Published: July 2023

This paper analyzes the legal formulae in the language of two extensive medieval notarial documents. The first text, dating from 1210, was written in Latin, while the other, from 1253, is a translation of the earlier document in the Romance language of the time, following the command of Alfonso X to “translate into Romance... letters written in Latin... so that all women and men may understand them”. This allows for a direct comparison of the legal expressions in the two documents and thus for a study that sheds light on the origins of a considerable number of legal constructions and their transfer from Latin to Romance. While situated within the framework of Philology, the analysis also takes into account the contributions of other, more recent, approaches to the study of phraseology, such as that of Construction Grammar, also allowing for an appraisal of the capacity and technique displayed by the scribes of that period to manage two different registers, notarial Latin and Romance, throughout the process of translation.
Canon literario y fraseología en el proceso de codificación gramatical del castellano (1492-1770)
Authors:   Universitat de València (España), Martínez Alcalde María José
Published: July 2023

The classic definition of grammar as a discipline linked to the notion of correctness and use by renowned authors is transferred to the process of grammatical coding of the Spanish language, with various nuances that concern the chronology of the works, but also their objectives. The discrepancy on the possibility of establishing a canon of Castilian authors similar to Latin as the basis of the grammatical norm can be observed, together with its relationship with the parallel resource to Phraseology, in particular to proverbs or phraseological units that are identified within this denomination. This work focuses on the study of these issues in the autochthonous Castilian grammars of the interval between the publication of Nebrija’s Gramática sobre la lengua castellana (1492), and the period of the eighteenth century prior to the publication of the first Gramática of the Royal Spanish Academy.
Unidades fraseológicas suboracionales en un corpus de textos jurídicos: el esquema [PREP. + SUST. + PREP.]
Authors:   Università degli Studi di Verona (Italia), Hourani-Martín Dunia
Published: July 2023

In this paper I present an analysis of prepositional constructions corresponding to the schema [prep. + noun + prep.], which are used in a corpus of Hispanic legal texts to express a specific judicial action. In order to do so, first of all, all the combinations registered in the CRIMO corpus are extracted automatically. Then, they are grouped according to the meaning they refer to and, after a formal analysis following the cohesion tests established by Montoro del Arco (2006: 190-197), their status as intrasentential phraseological units with prepositional or adverbial function is validated. Finally, I compare from a qualitative perspective the similarities and differences among the variants within the same group, highlighting aspects related to their geographical distribution if they are relevant.
Fraseología jurídica en la obra de Benito Pérez Galdós

Published: July 2023

In previous works (Tabares Plasencia 2018, 2020, 2021a, 2021b), the importance of legal elements in Spanish literature has been pointed out. This article will mainly offer a sample of verbonominal constructions, together with an analysis of the abundant legal phraseology present in the work of one of the most prolific writers of our literature, Benito Pérez Galdós. Beforehand, however, the author’s relationship with Law, as well as the characteristics of the CORLITES corpus (Corpus of Spanish Literature), will be briefly outlined. This corpus has been compiled with the aim of extracting and analysing, from a diachronic point of view, the legal terminology and phraseology used in Spanish literary texts from the origins of the Spanish language until the first two decades of the 20th century, with a special emphasis on the CORLIGA subcorpus (Corpus of Literature-Galdós).
Fraseología y literatura: el caso del Quijote

Published: July 2023

Cervantes’s literary work has been the object of study of a wide variety of disciplines, among which Philology undoubtedly stands out. This paper aims to explore the author’s use of what Coseriu called «repeated discourse», namely, phraseology. For this purpose, we will reflect on the use of literary texts as a source of linguistic research, on the typology of the fixed units used in the novel and on the functions that Cervantes assigns to them.
La fraseología como recurso estilístico y expresión identitaria: el ejemplo de L’empire du mensonge, de Aminata Sow Fall
Authors:   Université Gaston Berger (Senegal), Voltaire Dioussé Gustave
Published: July 2023

In this paper, literature is considered as a corpus for the study of phraseology. Specifically, the novel analysed is L’empire du Mensonge by Aminata Sow Fall, one of the most outstanding figures in Senegalese literature. Applying the theoretical-methodological foundations initially proposed, the reading of this novel has allowed to create an inventory list of twenty-five phraseological units (locutions, proverbs, and routine formulae), not of French, but of the author’s first language, namely Wolof. With this work, and due to the peculiarity of the novel under analysis, in which an outstanding presence of words and statements of the Wolof language can be found, I contemplate a double purpose in its use of phraseology: as a stylistic resource used in order to be understood by the Senegalese reader, and as the expression of identity

Reflexiones acerca de la traducción de elementos del «discurso repetido»
Authors:   Universität Leipzig ( Alemania), Wotjak Gerd
Published: July 2023

The use of repeated discourse justifies the consideration of lato sensu phraseology. Among the various units covered by this broad concept of Phraseology, non-idiomatic verbonominal constructions (NVC) (non-idiomatic collocations) and idioms have been chosen for this analysis and reflection. For all the subgroups of these NVCs it is necessary to specify, in their citation form, the semanticity (woman, man, child, etc.), the semantic role and the syntactic function of the lexical units or fillers which fill the argument slots of the verb and evoke both its meaning and its syntagmatic semantic macrostructure (SSM). This is due to the fact that only (partially) transparent NVCs have also a literal meaning and an extended midstructure with a communicative potential that can make their translation into other languages difficult, not only in a playful use (puns).
Psychosocial Factors Affecting Self-Regulated Learning among Indonesian Islamic College Students: The Mediating Role of Perception Feedback
Authors: Mutiah Diana , Paulina Melisa , Putra Muhammad Dwirifqi Kharisma
Published: July 2023

In facing various problems during the online learning process, individuals need to have self-regulated learning to be able to undergo online lectures optimally and effectively. Hence, student’s knowledge increases, and learning objectives are achieved. This study aims to investigate the mediating effect of self-efficacy in the relationship between perception feedback on self-regulated learning in undergraduate students. Whether the mediation had varying effects on different age levels and sex differences was also examined. The sampling technique used in this study is non-probability sampling with 410 students. This study uses a quantitative approach with path analysis. In this study, researchers used confirmatory factor analysis (CFA) using Lisrel 8.8 to test the instrument's construct validity. The results showed a direct effect from the independent variables, namely self-efficacy, family support, and an indirect effect through mediator variables, namely self-efficacy, family support, friend support, and gender. The effect of self-efficacy and family support is partial mediation on self-regulated learning. In contrast, peer support and gender demographic variables have a perfect mediating effect on self-regulated learning with perception feedback as a mediator.

Personality and religiosity have been found to be the most important predictors of marital satisfaction in empirical studies. However, there has not yet been any research that examines the causal relationship between personality and religiosity and the impact of both on marital satisfaction in the same model, from the perspective of da'wah psychology. In the current study, we aimed to verify the relationship between personality and marital satisfaction is mediated by religiosity, as it is perceived as motivation from the perspective da’wah of psychology. This research uses a quantitative approach, and statistical analysis methods in path analysis research using Mplus software version 8.0. The sample consisted of 347 participants. The results show that 1) Personality type affects marital satisfaction mediated by religiosity fit with data significantly and negatively and 2) Negative personality emotionality affects marital satisfaction both directly and through religiosity as a mediator variable, where religiosity is as a partial mediator. The perspective of da'wah psychology is an approach that integrates religious principles with psychological knowledge so that it can provide a deeper understanding of helping individuals develop their potential and improve the quality of their lives and provide a framework for understanding the role of religiosity by emphasizing the importance of applying religious values in shaping marital satisfaction. The implications of this study highlight the importance of religiosity as a mediator in overcoming problems and suppressing negative emotionality so as to increase marital satisfaction in each couple within the framework of da'wah psychology.

Статья посвящена результатам исследования методами нейтронной томографии и дифракции двух серебряных перстней конца I - перв. пол. II в. н. э. и трех бронзовых монет первой трети III в. н. э. из раскопок могильника римского времени Фронтовое 3 (Юго-Западный Крым). Исследования серебряных корродированных перстней, выполненные методом нейтронной томографии и дифракции, позволили диагностировать процесс коррозионного растрескивания под напряжением, возникающего в результате применявшейся в римское время техники изготовления перстней (ковка с наклепом). Анализ фазового состава металла римских фоллисов по методу нейтронной томографии и дифракции показал, что они были изготовлены из тройной бронзы без присадки серебра; это отличает рецептуру их сплава от применявшегося для выпуска таких монет в западных провинциях Римской империи. Методом нейтронной томографии также установлено отсутствие следов серебрения на поверхности фоллисов перв. трети IV в. н. э. из Фронтового 3

The paper describes results of the analysis of two silver rings dating to the end of the 1st - first half of the 2nd centuries AD and three bronze coins from the first third of the 3rd century AD found during excavations of Frontovoye 3. The site is a cemetery of the Roman period in Southwestern Crimea. The analysis of corroded silver fingerrings was performed using methods of neutron tomography and diffraction. Methods of neutron structural diagnostics offered an opportunity to determine the process of corrosion cracking caused by the forging technique used in the Roman time. The analyzed phase composition of the metal the Roman folles were made from demonstrated that three-component bronze without silver addition was used in their production, which means that their formula is different from that applied to mint such coins in western provinces of the Roman Empire. The neutron tomography method did not find any traces of silver plating on the surface of the folles dating to the first third of the 4th century AD discovered at Frontovoye 3.

Статья посвящена введению в научный оборот и анализу серии клейм на тонкостенных красноглиняных сосудах, обнаруженных при изучении Елизаветовского городища на Дону в одном из строительных комплексов второй половины IV в. до н. э. Как правило, находки подобного рода связываются исследователями с мерными сосудами и являются достаточно редкими для памятников скифо-античного времени Северного Причерноморья. В материалах Елизаветовского городища такие находки обнаружены впервые. Присутствие на этом поселении фрагментов таких сосудов, а также обнаруженные в разные годы свинцовые гири свидетельствуют о применении в торговых операциях на городище стандартизированной системы мер и весов и развитии здесь не только оптовой, но и мелкой розничной торговли.

The paper introduces into scientific discourse and analyzes a series of stamps on red clay thin-walled vessels found during excavations of the Elizavetovskoye fortified settlement in the Don region in one of construction complexes dating back to the second half of the 4th century BC. Scholars tend to link such finds to measuring vessels which are rather rare for Scythian-Ancient Greek sites in the North Pontic region. These vessels are the first finds of this type discovered at the Elizavetovskoye settlement. Presence of fragments of this kind of vessels as well as lead weights discovered in various years suggest the use of a standardized system of weights and measures in trade transactions and development of not only wholesale but also retail trade at Elizavetovskoe settlement on the Don.
Altar 1 from Uaxactun (Petén, Guatemala): Analysis of the Zoomorphic Monument of the Ancient Maya
Authors: Сафронов А.В.
Published: July 2023

Одним из слабоизученных памятников Вашактуна - важного политического центра древних майя является алтарь 1, обнаруженный в 1921 г., но до сих пор лишь поверхностно описанный в историографии. Это монумент нерегулярной формы, представляющий собой изваяние в форме черепахи и относящийся к категории т. н. зооморфных алтарей - изображений мифического животного. Панцирь черепахи покрыт плохо сохранившимся рельефом, детальный анализ которого стал возможен благодаря созданию 3Э-модсли алтаря, подготовленной в рамках исследования Регионального археологического проекта Вашактуна (PARU). Данная публикация по священа анализу иконографии и определению роли монумента в истории города. Алтарь 1 связан с мифологическим сюжетом о Боге кукурузы, воскресающем из Космической черепахи, символизирующей земную твердь. В иконографии монумента Бог кукурузы имперсонируется с царем «Носильщик солнца» (его имя записано в головном уборе), правившим на рубеже IV-V вв. и упоминаемым на стелах 4 и 5, а также на настенных росписях здания B-XIII. По аналогии со сходными памятниками мы предполагаем, что алтарь 1 из Вашактуна являлся посмертным монументом «Носильщика Солнца» и был установлен между 402 и 406 гг.

Altar 1 ol Uaxactun discovered in 1921, is one ol the not well-known monuments ol that important Classic Maya political center and still only superficially described in historiography. That is a monument ol irregular shape that depicts a turtle and belongs to the category ol zoomorphic altars - the images ol mythical monsters. The turtle carapace is covered with poorly preserved reliel, a detailed analysis ol which was made possible thanks to the production ol a 3D model ol the altar, prepared as part ol the research work ol the Regional archaeological project ol Uaxactun (PARU). This publication is devoted to the analysis ol iconography and the definition ol the role ol the monument in the history ol the city. Altar 1 is associated with a mythological story ol Maize God resurrecting lrom a Cosmic Turtle symbolizing the Earth. In the iconography ol the monument the Maize God is impersonated by the king ol Uaxactun known as «Sunraiser», his name is recorded in the headdress, who ruled at the turn of the IV-V cent. and is mentioned on stelae 4 and 5, as well as on the murals of structure B-XIII. By analogy with similar monuments, we assume that Altar 1 of Uaxactun could be a posthumous monument of the «Sunraiser» and was erected between 402-406 AD.

Фронтовое 3 - новый могильник римской эпохи в Юго-Западном Крыму, полностью изученный экспедицией ИА РАН в 2018 г. Среди погребальных сооружений, открытых на памятнике, наиболее многочисленны подбойные могилы и грунтовые склепы. В статье рассматривается вопрос о культурном взаимодействии групп населения, использовавших эти типы погребальных сооружений, по данным изучения лепной керамики. Представленное исследование посвящено сравнительному анализу форм лепных сосудов, найденных в подбойных могилах и грунтовых склепах. В нем применяется методика анализа форм глиняных сосудов, разработанная в рамках историко-культурного подхода к изучению древней керамики. Установлено, что традиции создания форм лепных сосудов, найденных в рассматриваемых типах погребальных сооружений, характеризуются большим сходством. Результаты сопоставления данных о формах лепных сосудов с технологией их изготовления, планиграфией и хронологией могильника свидетельствуют, что основной причиной этого сходства является смешанность населения, хоронившего в разных типах могильных сооружений на некрополе Фронтовое 3.

Frontovoye 3 is a new cemetery of the Roman period in the southwestern Crimea that was fully excavated by the Institute of Archaeology, RAS, in 2018. Among funerary constructions discovered at the site, the most numerous are niche graves and inground vaults. The paper explores the issue regarding cultural linkages among the population groups that used these types of funerary constructions based on data on the examined hand-made ceramics. This study focuses on comparative analysis of the forms of handmade vessels discovered in the niche graves and the burial vaults. It relies on the methodology of analyzing forms of clay vessels developed proceeding from the historical and cultural approach employed in studies of ancient ceramics. It was found that the traditions of creating the forms of hand-made vessels retrieved from such funerary constructions demonstrate a high level of similarity. Comparison of the data on the forms of hand-made vessels, their production technology and spatial distribution and chronology of the cemetery provide evidence that the main reason of this similarity is the mixed character of population groups that buried their dead in various funerary constructions at Frontovoye 3.

Specifications Grading at Scale: Improved Letter Grades and Grading-Related Interactions in a Course with over 1,000 Students
Authors: McKnelly Kate J. , Howitz William J. , Thane Taylor A. , Link Renée D.
Published: July 2023

In our previous work we piloted a specifications grading system in an organic chemistry laboratory course with 37 students. Our current work describes the scale up of that specifications grading system to a course with over 1,000 students. Strategies used for keeping the system manageable and mitigating the time commitment required to do so are described. We found that the time necessary to grade student work and manage the specifications grading implementation of the course was not any greater than for the previous, points-based course, that grade-related interactions were more positive, and that student letter grades increased. Despite the increase in final letter grades, we encountered some resistance to the grading system from students and graduate teaching assistants. Here, we explore their concerns and address the difficulty of alternative grading methods in overcoming habituation to traditional points-based grading systems. Future work is needed to evaluate student and graduate teaching assistant buy-in, to assess potential improvement in student work, and to address questions regarding equity in specifications grading systems.
Ultrasensitive Ionophore-Based Liquid Sensors for Colorimetric Ion Measurements in Whole Blood
Authors: Ghanbari Ghalehjoughi Nasrin , Wang Renjie , Kelley Savannah , Wang Xuewei
Published: July 2023

Self-monitoring of electrolytes using a small volume of capillary blood is needed for the management of many chronic dis-eases. Herein we report an ionophore-based colorimetric sensor for electrolyte measurements in a small drop of blood. The sensor is a pipette microtip preloaded with a segment of oil (plasticizer) containing a pH-sensitive chromoionophore, a cation exchanger, and an ionophore. The analyte is extracted from the sample into the oil via a mixing protocol controlled by a stepper motor. The oil with an optimized ratio of sensing chemicals shows an unprecedentedly large color response for elec-trolytes in the very narrow concentration range of clinical relevance. This ultrahigh sensitivity is based on an exhaustive re-sponse mode with a novel mechanism of defining lower and higher limits of detection. Compared to previous optodes and molecular probes for ions, the proposed platform is especially suitable for at-home blood electrolyte measurements because 1) the oil sensor is interrogated independently from the sample and, therefore, works for whole blood without requiring plasma separation; 2) the liquid sensor does not need individual calibration as the consistency between sensors from the same solution or different batches of solution is high compared to solid sensors such as ion-selective electrodes and optodes; 3) the sensing system consisting of a disposable oil sensor, a programmed stepper motor, and a smartphone is portable, cost-effective, and user-friendly. The accuracy and precision of Ca2+ sensors are validated in 51 blood samples with varying con-centrations of total plasma Ca2+. Oil sensors with an ultrasensitive response can also be obtained for other ions such as K+.
Air-stable Copolymer Exhibiting Near-Infrared Long-Persistent Luminescence
Authors: Lin Zesen , Li Maosheng , Kabe Ryota
Published: July 2023

Organic materials exhibiting long-lasting emission in the near infrared are expected to have applications in bio-imaging and other areas. Although room temperature phosphorescence and thermally activated delayed fluorescence display long-lived emission of approximately one minute, organic long-persistent luminescence (OLPL) systems with a similar emission mechanism to inorganic persistent emitters can emit for several hours at room temperature. In particular, OLPL with a hole-diffusion mechanism can function even in the presence of oxygen. However, ionic materials lack long-term stability in neutral organic host owing to aggregation and phase separation. In this study, we synthesised polymers with stable near-infrared persistent luminescence at room temperature via the copolymerisation of electron donors and acceptors. The copolymers exhibit long-persistent luminescence (LPL) at temperatures below the glass transition temperature and can be excited by approximately the entire range of visible light. LPL properties and spectra can be controlled by the dopant.

Published: July 2023

Introduction Gingivitis is an inflammatory condition caused by bacterial biofilm that accumulates on teeth. It is a complex disease that involves the loss of attachment around teeth due to the action of microorganisms which is a major cause of tooth loss in adults. Tooth brushing is the most accepted practice for the maintenance of oral hygiene. Chemotherapeutic agents such as mouthwashes containing chlorhexidine have been suggested as an adjuvant in reducing plaque formation however they can be associated with certain undesirable adverse effects. Keeping that in mind a novel traditional Indian method called oil pulling is regaining popularity. Oil pulling involves swishing oil in the mouth for oral and systemic health benefits.Aim The present study focused on benefits of oil pulling in maintaining daily oral hygiene and its effects on oral microfloral colony counts.Methodology The study period was six months and the duration of the study was 21 days. Evaluation of salivary pH dental plaque and gingivitis was done at baseline 0 after 7 14 and 21 days. After recording baseline data patients underwent thorough scaling and root planing. Patients were divided randomly into Group 1 and 2 and bottles containing mustard oil and rice bran oil to swish were distributed respectively. Instruction to swish 10 ml of the given oil twice daily for about 1 to 2 minutes was given.Results Reduction in the colony count was greater with rice bran oil than mustard oil.Conclusion Rice bran oil and mustard oil were found to be effective in the maintenance of oral health. Rice bran oil was found to be more effective compared to mustard oil in reducing the oral microbial colony count and plaque.

Authors: Yadav Ashish , Vijay Amit
Published: July 2023

Background and Aim The Indian population is mostly undiagnosed with diabetes due to a lack of awareness leading to serious and long-term complications. Diabetic complications can be prevented by early detection. Thus there is a need to increase opportunities for reliable diabetes screening and early detection. Therefore this study aimed to evaluate gingival crevicular blood for screening the diabetic population.Methods A cross-sectional study was conducted in the Department of Periodontology of a Dental College and Hospital in Jaipur comprising 150 patients 25-70 years who fulfilled the inclusion criteria. The excess blood produced during the periodontal examination was carefully collected and blood glucose levels were estimated using the self-monitoring device glucometer. Glucose levels were also evaluated from the Finger-prick blood samples using a glucometer. Data obtained were statistically analyzed using Studentrsquos t-test and Pearsonrsquos correlation test.Results The study provided a statistically strong correlation between gingival crevicular blood GCB and capillary finger-prick blood CFB. The mean GCB level was 136.13 plusmn 36.95 mgdl and the CFB levels were 161.62 plusmn 51.84 mgdl. A significant correlation was observed r0.887 plt0.01.Conclusion The study indicates that GCB collected during the periodontal examination can be a good source of blood for glucometric analysis and could be used as a reliable effective and non-invasive chair-side mode of monitoring or screening diabetes in periodontal patients.

Airborne particulate matter (PM) are a major environmental pollutant adversely affecting human health. Exposure to atmospheric PM is correlated with significant damages to physiological systems from respiratory and circulatory level to reproductive and central nervous systems. The paper describes the elemental composition of a particular category of PM2.5 – microspheres, originate in exhaust pipes of automobiles and deposited onto vegetation planted along the roads. Microspheres were characterized using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX). Based on size and chemical composition, the hazard on human health of identified microspheres was evaluated. SEM investigation showed that microspheres size was between 3 and 0.5 μm. EDX analysis indicate that microspheres have a complex elemental structure, which concentrate mainly Si and Al in combination with Mg, Na, Fe, K, Ca and Cl, and seldom Ba and Ti. Our results showed that detected airborne microsphere are breathable and potential harmful to human health.
PPS-FPCM: PRIVACY-PRESERVING SEMI-FUZZY POSSIBILISTIC C-MEANS

Applying traditional clustering techniques to big data on the cloud while preserving the privacy of the data is a challenge due to the required division and exponential operations in each iteration, which complicate its implementation on encrypted data. Several existing approaches are based on approximating the formulas of centers, weights, and memberships as three polynomial functions according to the multivariate Taylor formula. However, they usually suffer an increase in complexity and a slight drop in accuracy. In this paper, a novel Privacy-Preserving semi-fuzzy clustering algorithm based on the possibilistic paradigm, termed PPS-FPCM, is presented. Its main feature is that it avoids exponentiation and division operations, at each iteration, without losing accuracy. By restricting the typicality to an ordered set of discrete values between zero and one decided by the data owner (DO), the computation is simplified. The second key idea is the use of this soft typicality to detect outliers and compute the corresponding semi-fuzzy memberships, which is used to increase the in-between cluster distance. However, the initial typicality requires a magnitude relation comparison, which is still difficult to do over encrypted data. In this research study, we show how the existing incomplete re-encryption method can be used to tackle this problem. In each iteration, centers and distances to the new centers are computed on a calculator cloud server (CaCS) which is responsible for storing the cipher texts of the (DO)’s data and processing them. Then, CaCS sends the incompletely re-encrypted difference between these distances and iteratively updated bin values that correspond to the discrete possibilistic memberships that are initially decided by the (DO) to the comparator cloud server (CoCS). CoCS decrypts the difference and returns the results of comparisons. When CaCS receives the results of comparison from CoCS, it decides on an appropriate soft typicality or resends the difference of the same distance to another bin value. The required number of comparisons is O(log the number of bins). CaCS iteratively computes the corresponding semi-fuzzy memberships, computes the refined memberships, and updates the centers. In the end, CaCS sends the final soft memberships and centers to the (DO). The proposed algorithm is applicable to normal data and homomorphically encrypted data, is more effective than several related algorithms, and can produce accurate results using large enough (16 or more) discrete values with a high reduction on runtime as the number of comparisons is much less complex than exponential and division operations with added communication cost between CaCS and CoCS.

EPS systems integrate Advanced Driver Assistance Systems (ADAS) while the driver controls the steering wheel. Touch sensors, torque, and position sensors improve driver involvement, safety, and control in EPS. ADAS features like lane-keeping assistance and adaptive cruise control are activated by the driver’s steering wheel touch. EPS with driver-enabled ADAS integration, using touch sensors, empowers drivers while leveraging enhanced automation. The vehicle model design incorporates touch sensors, Arduino, and motor drivers to enable Advanced Driver Assistance Systems (ADAS) exclusively when the driver holds the steering wheel. The touch sensors detect the driver’s touch on the steering wheel, triggering the ADAS functionalities and allowing the vehicle to move. The Arduino microcontroller, equipped with embedded C code, processes the touch sensor inputs and communicates with the motor drivers to initiate vehicle propulsion. The embedded C code facilitates real-time monitoring and control of the touch sensor inputs, enabling a seamless integration between driver interaction and vehicle movement, thereby enhancing both safety and user experience

Objective: To carry out empirical research on the role of project-achieving quality control circle (QCC) in constructing a new model of contactless medical service for outpatients. Methods: A QCC, consisting of information office members from a grade A tertiary hospital in Wenzhou, was established to conduct a research project with the theme “Constructing a new model of contactless medical service based on outpatients’ experience.” According to the ten steps and PDCA cycle, an analysis was carried out before and after the QCC activities, focusing on improving pre-consultation services, providing steward-like services, and facilitating post-consultation management. Results: After the QCC activities, the mobile appointment rate, missed appointment rate, the proportion of smart check-ins, and the average check-in time were 55.68%, 4.02%, 39.75%, and 8.24 ± 3.66 min, respectively; in contrast, before the activities, they were 32.00%, 7.88%, 0.00%, and 14.96 ± 4.98 min, respectively; the difference between the two groups was statistically significant (χ2 = 3480.112, 4994.496; Fisher’s exact probability = 963788.570; t = 5.323, P < 0.001). Many experts have also visited the hospital to learn about this system, thus rendering social and economic benefits. Conclusion: Project-achieving QCC activities are suitable for complex situations, such as constructing a new model of contactless medical service, and can significantly improve outpatient service quality, enhance patients’ experience, and improve the abilities of circle members.
