Cadre juridique des rejets de médicaments humains dans l’eau et ses perspectives d’évolution
Authors: MARCHAND-PILARD M.
Published: November 2021

"Dans l’Union européenne (UE) la source principale de médicaments humains dans
l’environnement est l’excrétion des patients. Ces médicaments n’ont pas été conçus en considération de
leur devenir postutilisation et les stations de traitement des eaux usées (STEU) urbaines n’ont pas été
conçues pour les éliminer. Face à cette situation a été développée une démarche en trois étapes. La
première phase a consisté à identifier les acteurs du cycle de vie des médicaments et analyser les
réglementations françaises et européennes applicables. La deuxième phase a permis de comparer les
modes de gestion de cette pollution en Allemagne, Suède et Suisse pour identifier les solutions mises en
place et les incitations qui ont conduit ces États à agir. La dernière phase consistera à regrouper les
précédents résultats pour identifier les mesures coercitives et/ou incitatives transposables en France,
voire à l’UE pour déployer ces solutions. Les deux premières phases ont permis de mettre en évidence les
limites et évolutions des réglementations européennes et françaises en matière de rejet des médicaments
humains dans l’eau. Il en ressort que la France n’a pas de cadre réglementaire approprié pour gérer cette
pollution, et semble fortement attachée aux actions de réduction à la source. Une intervention sur
l’ensemble du cycle de vie des médicaments serait pourtant nécessaire. Des actions de réduction à la
source ne sont pas efficaces à court terme et les actions correctives sont coûteuses et insuffisantes seules.
Les réglementations et politiques publiques doivent être décloisonnées pour aller vers des mesures
transversales mettant tous les acteurs à contribution. Les évolutions européennes récentes (nationales et
supranationales) laissent présager la demande de traitements avancés dans les STEU et un cadre plus
contraignant pour le retour au sol des boues, mais se pose la question du financement."

Business Sustainability: The Trend of Human Resource Disclosure Based on Malaysian Evidence
Authors: Abdullah Norhayati , A.H Fatima  , Maliah Sulaiman
Published: November 2021

This paper aims to investigate the trend of human resource disclosure (HRD) quality based on publicly disclosed annual reports of 235 Malaysian listed companies. The data was collected through content analysis method using HRD index. The results reveal that there is an increasing trend of HRD quality from 2010 to 2014.  However the significant increase is only between 2012 and 2013. This study provides empirical support for Institutional theory’s coercive isomorphism, through its findings on quality of HRD. This is because, the related disclosure regulations and the Malaysian government policy through Malaysia Plan may have significantly influenced firms to increase HRD quality in their annual reports.
A Methodology to Investigate Powered Two-Wheeler Rider’s Comfort over Road Sections with Skew Superelevation
Authors: Lemonakis Panagiotis , Kaliabetsos George , Moisiadis Nikolaos , Eliou Nikolaos
Published: November 2021

The proper surface water drainage not only affects vehicle movement dynamics but also increases the likelihood of an accident since inadequate drainage is associated with potential hydroplaning and splash and spray driving conditions. Nine solutions have been proposed to address hydroplaning in sections with inadequate drainage e.g. augmented superelevation and longitudinal slope, reduction of runoff length, and skew superelevation. The latter has been extensively implemented in highways recently, enhancing the safety level in the applied road segments regarding the effective drainage of the rainwater. However, the concept of the skew superelevation has raised concerns regarding the level of driver’s comfort when traveling over skew superelevation sections particularly with high speeds. These concerns were alleviated through the concept of the round-up skew superelevation which reduces both the lateral and the vertical acceleration imposed on the drivers and hence, improves comfort and traffic safety. The present study investigates the behaviour of power two-wheeler riders since they are susceptible to any changes on the pavement surface and therefore a comparison between the traditional superelevation practice and the skew superelevation concept is of paramount importance. The methodology is based on the utilization of sophisticated software to design the model of the road for several values of longitudinal slopes. Based on the values of the slopes and the use of mathematical equations, the accelerations imposed on the wheel of the motorcycle were calculated. Since the final aim of the study is the influence of the skew superelevation to the rider, it was deemed necessary to convey the calculated accelerations from the wheel to the rider. That was accomplished by implementing the quarter car suspension model adjusted to the features of two-wheeler vehicles. Finally, the accelerations derived from this process evaluated according to specific thresholds based on the literature which correspond to certain levels of comfort. The most important conclusion drawn is that the comfort of the riders is not dependent to a great extent on the form of the road gradient because the vertical acceleration imposed on the riders took similar values regardless of the value of the longitudinal slope.

Published: November 2021

Today, globalization as well as the advancement of technology is narrowing the distances of nations. Vietnam has become an attractive destination of tourists due in part to its charm, natural beauty, as well as its rich history and culture. The aim of this research is to study the effects of emotional experience factors on tourists’ satisfaction and their willingness to recommend the destinations, this study follows revised Destination Emotion Scales (DES) model. The survey was carried out with 224 foreign tourists who have travelled to a few famous places in Vietnam at least one time by both online and offline method. The methodology used in our research is a quantitative method. SPSS software 20 and AMOS 21 with SEM (structural equation modelling) were used to carry out analyzing on data gathered through a survey. This research found that the emotions of joy and love as significant influences on tourists’ satisfaction and its effect on intention to recommend while exploring whether or not the emotion of positive surprise does not support this relationship. The research makes a significant contribution to tourism marketing in Vietnam because some of the empirical findings found in the study deal with aspects of tourists’ satisfaction and their willingness to recommend necessary to improve tourism.

Problems of Diagnosis, Conservative Treatment and Long-Term Results of “Mallet Finger” Fracture
Authors: Bezuhlyi A.A. , Lysak A.S.
Published: November 2021

Summary. Distal phalanx dorsal edge fracture is treated in a relatively simple closed manner during the first weeks after injury. The role of the distal interphalangeal joint in the upper extremity integral function reaches conventionally only a few percent. This may lead to insufficient attention and a large number of mistakes in diagnosis and treatment of such injuries, which in turn provokes complications that are much more difficult to treat than the primary injury. This article considers the most common problems of diagnosis and treatment of “mallet finger” fractures. Advantages and disadvantages of various techniques used in the treatment of such fractures in acute and neglected cases are considered and analyzed.

Objective: to study the effect of distal phalanx dorsal edge avulsive fractures on function of the upper limb, quality of life, and depression rate in long term period after injury.

Materials and Methods. Data from 11 patients (8 (88%) males and 3 (12%) females) with neglected cases of distal phalanx dorsal edge avulsive fractures were studied. QuickDASH questionnaire and visual analog scales were used to study impaired quality of life and depression rate in such patients. Indicators that lead to the need for surgery in long term period after injury have been identified.

Results. It was determined that in long term period, in patients with a “mallet finger” fracture, function of the upper extremity suffered significantly and was 29.2±20.2 points (range 2.3-75) according to QuickDASH scale. This condition also significantly affected the general well-being of the patient. Average value of impaired quality of life was 43.6±24.6 (range 0-90 points), and depression rate due to upper extremity dysfunction was 44.6±22.7 (range 0-90 points).

Conclusions. Despite the relatively minor injury, high rates of dysfunction, impact on quality of life and depression rate indicate the need to restore finger function even in long term period after injury.
Treatment of Chronic and Complicated Ruptures of the Rotator Cuff of the Shoulder
Authors: Strafun O.S. , Sukhin O.Yu. , Lysak A.S. , Bohdan S.V.
Published: November 2021

Relevance. The etiology of ruptures of the rotator cuff of the shoulder (RC) is represented by a variety of diseases, including age-related degeneration, low- and high-energy trauma. Most often, a rupture of the RC, combined with trauma, occurs with anterior dislocation of the shoulder – in 56% of patients. The “terrible triad” of the shoulder, which leads to a loss of function and disability in patients, is diagnosed in 9-18% of patients. RC ruptures of <1-1.5 cm throughout the entire thickness of the tendon have a high risk of progression and formation of a massive rupture of the RC. According to various authors, massive ruptures occur in 40% of all RC ruptures.

Objective: to evaluate the results of surgical treatment of patients with old and complicated ruptures of the RC.

Materials and Methods. From 2016 to 2021, in the SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine”, Department of Microsurgery and Surgery of the Upper Limb, 140 patients with a ruptured RC were treated. The patients underwent: suture of the RC under arthroscopic control, open RC suture, transposition of the latissimus dorsi tendon into the RC defect, implantation of biodegradable InSpace balloon, or implantation of a biomatrix into the RC defect and reverse shoulder arthroplasty.

Results. The function was assessed before surgery and in the long-term postoperative period using the Constant-Murley Score. In 5 patients with an implanted balloon, the score increased from 34-38 to 56-61 in 8-12 months. In 7 patients with reinforced biomatrix implantation, the score increased from 34-38 to 65-69 in 9-12 months. In 7 patients with transposition of the latissimus dorsi tendon, the score increased from 35-37 to 68-75 in 9-12 months. In 10 patients with reverse arthroplasty, the score increased from 30-34 to 58-65 in 12-18 months. In 82 patients, after the suture of the RC under arthroscopic control of the shoulder, the score increased from 36-40 to 78-82 in 12-18 months. In 29 patients with an open suture of the RC, the score increased from 34-38 to 68-75 in 12-18 months.

Conclusions. Early diagnosis and timely surgical treatment for the pathology of the RC make it possible to obtain the best results in the long-term postoperative period. Massive and old ruptures of the RC require a complete instrumental examination in the preoperative period. The degree of adipose degeneration and rotator arthropathy is of key importance for determining the operative tactics of surgical treatment.
Increased circulating LDL cholesterol increases myeloma tumour burden in vivo

Multiple myeloma (MM) is a fatal malignancy characterized by an expansion of malignant plasma cells in the bone marrow (BM) and associated with osteolytic bone disease. MM is preceded by the benign condition, monoclonal gammopathy of undetermined significance (MGUS). Understanding MGUS progression and development of MM bone disease is key for patient management. We and others have previously demonstrated that diet-induced obesity promotes myeloma progression, but the mechanisms underlying this remain unknown. The aim of the current study was to determine the effect of dietary cholesterol on MM development. A 2% cholesterol diet was used to increase circulating LDL in mice. Mice were randomly distributed to either a) cholesterol diet 4 weeks prior to 5TGM1 MM inoculation (pretreatment) or b) cholesterol diet 4 weeks prior to MM inoculation and continued for the entire experiment (continuous). Mice on the continuous cholesterol diet had increased tumour burden, associated with an increase in lipid droplet content of MM cells. No differences in tumour burden were seen in those mice where cholesterol diet was halted at time of MM inoculation. In vitro, myeloma cells cultured with delipidated FBS had a 50% reduction in viability after 72 hours. Rich cholesterol content lipoproteins (LDL) but not VLDL could restore MM cell viability, suggesting that cholesterol is responsible for this lipid-depletion effect. Taken together, our results show that high cholesterol promotes myeloma and results in a higher lipid content in myeloma cells, ultimately increasing BM tumour burden. Pretreatment with a cholesterol diet did not alter disease progression suggesting a direct pro-tumourigenic effect of cholesterol. These results demonstrate both the detrimental effect of cholesterol on myeloma progression and the potential for dietary intervention approaches.

Lições Preliminares sobre Liberdade Religiosa e Dignidade da Pessoa Humana
Authors: Marques Regina Jean
Published: November 2021

A liberdade religiosa possui um conjunto de elementos organizados que dão corpo para a sua ordenação. A primeira base da sua natureza está no significado dos princípios, fruto da Filosofia do Direito, e no Direito Natural, concomitantemente. Os princí-pios apontam para a essência do ser, o que confere a existência de liberdades fundamentais, e assinala a centralidade da dignidade da pessoa humana. A religião representa um pressuposto essencial para a vida humana e confere ao indivíduo a noção de que ele é portador de direitos e garantias fundamentais.
Direito Natural e Ordem Constitucional Brasileira
Authors: Fernandes de Araújo Marcos Paulo
Published: November 2021

Este artigo investiga a relação entre o Direito Natural e a ordem constitucional brasileira, marcada pelo predomínio do neoconstitucionalismo. Tomando como ponto de partida do Direito Natural moderno a doutrina de Guilherme de Ockham, avançando pelas de Hobbes e Locke e chegando até Sieyès, procura-se demonstrar como o neoconstitucionalismo, longe de constituir algo de novo é apenas um novo estágio de desenvolvimento dessas doutrinas que são, já em sua raiz, nominalistas e antimetafísicas, não consti-tuindo tampouco uma superação do positivismo kelseniano, já que, como este, também é voluntarista em suas bases. Ao final, propõe-se um retorno à metafísica tomista do ato de ser intensivo como fundamento da construção de uma ordem jurídica renovada.
Entendendo e Respondendo Ao Nosso Momento Transgênero
Authors: Anderson Ryan
Published: November 2021

No centro do momento transgênero encontram-se ideias radicais sobre a pes-soa humana—em particular, que as pessoas são o que afirmam ser, independentemente de evidências em contrário. Os ativistas transgênero não admitem que esta seja uma afirma-ção metafórica. Como eles não querem conduzir o debate no nível da filosofia, eles a dis-farçam como uma afirmação científica e médica. Mas a medicina moderna não pode reatribuir o sexo fisicamente, e tentar fazê-lo não leva a bons resultados do ponto de vista psicossocial. A medicina transgênero é baseada em uma cosmovisão transgênica. Mas a cosmovisão promovida pelos ativistas transgênicos é inerentemente confusa e cheia de contradições internas. Os ativistas nunca reconhecem essas contradições. Em vez disso, eles se apoiam oportunisticamente em qualquer afirmação que seja mais útil em um deter-minado momento. Mas, se puxarmos com mais força em qualquer dos fios com os quais a ideologia transgênero é tecida, a tapeçaria inteira se desfaz.

Published: November 2021

Os adeptos das Testemunhas de Jeová são motivados por sua crença a recusar-se à hemotransfusão, já que as ordenanças da Bíblia, segundo eles, são claras quanto à devida abstenção do procedimento. percorrendo as interpreta-ções e questionamentos que comportam toda a discussão da temática, e ainda levando em consideração o dualismo existente entre a vida digna e a vida biológica, o presente estudo analisa a natureza jurídica dos direitos envolvidos e da necessária ponderação dos mesmos, observando-se também as circunstâncias fáticas que envolvem os casos concretos. Com isso, pretende-se perceber quais são os argumentos constitucionalmente adequados para fundamentação e resolução do impasse que se origina quando da colisão entre os direitos envolvidos.

iCompare: A Package for Automated Comparison of Solar System Integrators*
Authors: Chernyavskaya Maria , Jurić Mario , Moeyens Joachim , Eggl Siegfried , Jones Lynne
Published: November 2021

We present a tool for the comparison and validation of the integration packages suitable for Solar System dynamics. iCompare, written in Python, compares the ephemeris prediction accuracy of a suite of commonly-used integration packages (JPL/HORIZONS, OpenOrb, OrbFit at present). It integrates a set of test particles with orbits picked to explore both usual and unusual regions in Solar System phase space and compares the computed to reference ephemerides. The results are visualized in an intuitive dashboard. This allows for the assessment of integrator suitability as a function of population, as well as monitoring their performance from version to version (a capability needed for the Rubin Observatory’s software pipeline construction efforts). We provide the code on GitHub with a readily runnable version in Binder (https://github.com/dirac-institute/iCompare).
Two New roAp Stars Discovered with TESS

Published: November 2021

We present two new rapidly oscillating Ap (roAp) stars, TIC 198781841 and TIC 229960986, discovered in TESS photometric data. The periodogram of TIC 198781841 has a large peak at 166.506 day−1 (1.93 mHz), with two nearby peaks at 163.412 day−1 (1.89 mHz) and 169.600 day−1 (1.96 mHz). These correspond to three independent high-overtone pressure modes, with alternating even and odd ℓ values. TIC 229960986 has a high-frequency triplet centered at 191.641 day−1 (2.218 mHz), with sidebands at 191.164 day−1 (2.213 mHz) and 192.119 day−1 (2.224 mHz). This pulsation appears to be a rotationally split dipole mode, with sideband amplitudes significantly larger than that of the central peak; hence, both pulsation poles are seen over the rotation cycle. Our photometric identification of two new roAp stars underscores the remarkable ability of TESS to identify high-frequency pulsators without spectroscopic observations.
A TESS Detection of Candidate Double White Dwarf Binary with a 3.54 days Period
Authors: Garza Navarro Natalia , Wilson David J.
Published: November 2021

We report the recharacterization of TIC 471013547 as an eclipsing white dwarf binary using data obtained with the Transiting Exoplanet Survey Satellite (TESS). Eclipses from both components are detected, and we find a period of 3.541056 ± 0.000185 days with an ephemeris of TJD = 2458441.434 ± 0.000209 days. Its shared features with other double white dwarf eclipsing binaries and its lack of infrared excess indicate that the system likely consists of two white dwarfs.

Published: November 2021

We describe a pipeline to measure scintillation in fast radio bursts (FRBs) detected by CHIME/FRB in the 400–800 MHz band by analyzing the frequency structure of the FRB's spectrum. We use the pipeline to measure the characteristic frequency bandwidths of scintillation between 4–100 kHz in 12 FRBs corresponding to timescales of ∼2–40 μs for 10 FRBs detected by CHIME/FRB. For the other two FRBs, we did not detect scintillation in the region our analysis is sensitive. We compared the measured scintillation timescales to the NE2001 predictions for the scintillation timescales from the Milky Way. We find a strong correlation to be an indication that in most instances, the observed scintillation of FRBs can be explained by the Milky Way.
Relict populations of Lyonetia ledi Wocke, 1859 (Lepidoptera, Lyonetiidae) from the Alps indicate postglacial host-plant shift to the famous Alpenrose (Rhododendron ferrugineum L.)
Authors: Huemer Peter , Schmid Jürg
Published: November 2021

Lyonetia lediWocke, 1859 (Lyonetiidae), was hitherto considered as a boreal species with a circumpolar distribution pattern and relict populations in isolated peat bogs north-east of the Alps (Austria, Czech Republic, Germany). In Europe it is known as a leaf-miner onRhododendron tomentosumStokes ex Harmaja (Ericaceae) as the primary host-plant and alsoMyrica galeL. (Myricaceae). The first record ofL. ledifrom the Swiss Alps onRhododendron ferrugineumL., the famous Alpenrose, indicates an ancient host-plant switch during postglacial periods whenR. tomentosumandR. ferrugineumshared habitat in the prealps. Conspecificity with northern populations is supported by the adult morphology and supplementing DNA barcodes (mtDNA COI gene).L. lediis the first obligatory leaf-mining species onR. ferrugineum. Details of the life-history and habitat are described and figured. The record finally substantiates the probability of an autochthonous population in Carinthia (Austria), from where the species was recently published as new to the Alps.
Protokoll der Jahresversammlung der Schweizerischen Entomologischen Gesellschaft vom 5. März und 21. Juni 2021 via Videokonferenz
Authors: Neumann Marc
Published: November 2021

Aufgrund der anhaltenden Corona-Pandemie musste die Jahresversammlung leider auf einen Tag reduziert werden und ohne physische Präsenz stattfinden. Sie wurde daher per Videokonferenz abgehalten. Der Präsident Oliver Martin hatte dafür ein Meeting via Zoom organisiert, das reibungslos ablief.

Trotz der erschwerten Umstände konnte ein interessantes Vortragsprogramm für die Jahresversammlung zusammengestellt werden. Den Themenschwerpunkt bildete die experimentelle Forschung mit Hymenopteren, jedoch aus ganz unterschiedlichen Fachgebieten. Das Programm startete mit dem Hauptvortrag von Yuko Ulrich, Professorin an der ETH Zürich, zum Thema Sozialverhalten und Krankheitsdynamik bei Ameisen. Darin gab sie einen Einblick, wie im Labor soziale Interaktionen und die Mechanismen der Entstehung von Arbeitsteilung untersucht werden. Als Modellorganismus diente die räuberische Ameisenart Ooceraea biroi, die keine Königinnen ausbildet. Stattdessen vermehren sich alle Individuen parthenogenetisch, was den Faktor der genetischen Varianz in Experimenten deutlich reduziert. Mittels Kameras über mehreren Dutzend Ameisenkolonien und Farbcodes auf den Tieren konnte das Verhalten und der Aufenthaltsort (im Nest oder ausserhalb des Nests) jedes Individuums analysiert werden. Dann wurde der Einfluss der Koloniegrösse, sowie der Mischung von Genotypen und Körpergrössen innerhalb einer Ameisengruppe auf das Verhalten der Tiere untersucht. Abschliessend berichtete Frau Ulrich über die neueste Forschung mit experimentell infizierten Ameisen. Von Pilzsporen befallene Tiere werden intensiver von Artgenossen betreut, wodurch ihre Überlebensrate stark steigt. In zukünftigen Studien sollen die genannten Untersuchungen über mehrere Generationen von Ameisen hinweg ausgedehnt werden.

Antibiotic overuse in obstetric and gynecologic procedures at Zagazig university hospitals: A prospective observational study
Authors: M. Magdy Ahmed , A. Seksaka Mahmoud , F. Balata Gehan
Published: November 2021

Surgical site infection (SSI) constitutes a major problem in healthcare in terms of healthcare cost, morbidity and mortality. Surgical antibiotic prophylaxis (SAP) is one of the effective strategies for SSI prevention. Poor adherence to SAP guidelines across different countries has been observed. Misuse of prophylactic antibiotics threatens patient safety and leads to an increase in the acquisition of antibiotic resistance. The aim of this study was to assess the utilization of SAP in obstetric and gynecologic procedures in terms of indication for prophylaxis, antibiotic selection, timing of administration and prophylaxis duration. A prospective observational study was conducted at the obstetrics and gynecology department of Zagazig University Hospital during the period from January 2020 to June 2020. Medical records of 264 women were recorded and evaluated. The American Society of Health-System Pharmacists (ASHP) therapeutic guidelines, World Health Organization (WHO) recommendations and The American College of Obstetricians and Gynecologists (ACOG) practice bulletin were used for data evaluation and hence women were stratified into two groups. For women who underwent procedures in which guidelines recommended the use of SAP (200 patients; 75.75%), 198 women (99%) received preoperative prophylaxis. None of women (0%) received the recommended first line antibiotic by guidelines while the most commonly used prophylactic antibiotics were Cefotaxime (86 patients; 43.43%) and Ampicillin-sulbactam (62 patients; 31.31%). Preoperative antibiotic prophylaxis timing was 0-60 minutes before skin incision. All women received postoperative prophylaxis that extended to an average of 7 days. Regarding the other group who underwent procedures in which prophylactic antibiotics weren’t recommended by guidelines (64 patients; 24.24%), 37 women (57.81%) followed the guidelines and didn’t receive SAP while 27 women (42.18%) received SAP. Poor adherence to guidelines recommendations regarding prophylactic antibiotic selection and prophylaxis duration was observed. High utilization rate of prophylactic antibiotics in procedures that didn’t require their use was reported..
Macroscopic descriptions of follower-leader systems

Published: November 2021

The fundamental derivation of macroscopic model equations to describe swarms based on microscopic movement laws and mathematical analyses into their self-organisation capabilities remains a challenge from the perspective of both modelling and analysis. In this paper we clarify relevant continuous macroscopic model equations that describe follower-leader interactions for a swarm where these two populations are fixed. We study the behaviour of the swarm over long and short time scales to shed light on the number of leaders needed to initiate swarm movement, according to the homogeneous or inhomogeneous nature of the interaction (alignment) kernel. The results indicate the crucial role played by the interaction kernel to model transient behaviour.
Adaptive event-triggered state estimation for complex networks with nonlinearities against hybrid attacks
Authors: Deng Yahan ,   School of Information Engineering, Guangxi City Vocational University, Chongzuo 532100, China, Meng Zhenhai , Lu Hongqian
Published: November 2021

This paper investigates the event-triggered state estimation problem for a class of complex networks (CNs) suffered by hybrid cyber-attacks. It is assumed that a wireless network exists between sensors and remote estimators, and that data packets may be modified or blocked by malicious attackers. Adaptive event-triggered scheme (AETS) is introduced to alleviate the network congestion problem. With the help of two sets of Bernoulli distribution variables (BDVs) and an arbitrary function related to the system state, a mathematical model of the hybrid cyber-attacks is developed to portray randomly occurring denial-of-service (DoS) attacks and deception attacks. CNs, AETS, hybrid cyber-attacks, and state estimators are then incorporated into a unified architecture. The system state is cascaded with state errors as an augmented system. Furthermore, based on Lyapunov stability theory and linear matrix inequalities (LMIs), sufficient conditions to ensure the asymptotic stability of the augmented system are derived, and the corresponding state estimator is designed. Finally, the effectiveness of the theoretical method is demonstrated by numerical examples and simulations.

The $ r $-Lah numbers generalize the Lah numbers to the $ r $-Stirling numbers in the same sense. The Stirling numbers and the central factorial numbers are one of the important tools in enumerative combinatorics. The $ r $-Lah number counts the number of partitions of a set with $ n+r $ elements into $ k+r $ ordered blocks such that $ r $ distinguished elements have to be in distinct ordered blocks. In this paper, the $ r $-central Lah numbers and the $ r $-central Lah-Bell numbers ($ r\in \mathbb{N} $) are introduced parallel to the $ r $-extended central factorial numbers of the second kind and $ r $-extended central Bell polynomials. In addition, some identities related to these numbers including the generating functions, explicit formulas, binomial convolutions are derived. Moreover, the $ r $-central Lah numbers and the $ r $-central Lah-Bell numbers are shown to be represented by Riemann integral, respectively.
Hydrogen Diffusion Influence on the Stabilizing Phases Behavior in the Ti-6Al-4V Alloy
Authors: Mohsun Mohammed Kasim
Published: November 2021

For obtaining a unique microstructure in Ti-6Al-4V, hydrogen is utilized as a temporary alloying element; therefore, the mechanism of hydrogen diffusion in α and β phases should be understood. In this study, the electrochemical hydrogenation was applied to the half-length of thin titanium rods, and the diffusion annealing heat treatment was implemented at different temperatures. The hydrogen diffusion coefficient of α phase (Dα) and the hydrogen diffusion coefficient of β phase (Dβ) was determined by employing Abaqus software and C# program for three different homogeneous microstructures. The obtained results showed that Dβ increases, and Dα decreases when the hydrogen concentration in β phase increases. Furthermore, it was observed that each microstructure has a specific temperature in which the maximum hydrogen amount is absorbed. The hydrogen uptake depends more on the volume fraction of β phase than the volume fraction of α phase, which is considered an obstacle to hydrogen diffusion in this alloy.

Experimental Study of Tool Wear when Milling Tropical Wood with Various Tool Materials
Authors: Nguyen Huu Loc
Published: November 2021

The paper presents a study on the performance of cutter tip for wood milling process. The tests were performed with the tropical wood samples which were milled in the double sided wood planer, the measured micro-geometrical parameters encompassing the linear wear and tooltip radius. The study primarily contributes to developing a far better understanding of the physical nature of cutting tool wear in response with the growing concern of many researchers. Given this basis, it does not only assist the selection of reasonable cutting tool but also enable the detection of the patterns in the cutting tool wear process. In terms of tool wear and bluntness, there has been a number of researches taking account into the physical nature of cutting tools, - providing basis for selection of cutting tools apart from clarification of the current pattern of tool wear and bluntness. The load applied to the cutter during wood milling is the load that changes marks periodically. When starting to work after tool sharpening and finishing, the first stage changes the microscopic geometry - tool run-in process (rapid initial wear), followed by constant conditions of wear before a rapid wear which leads to failure at last. The objective of this study is to determine the influence of the cutting path to the tooltip radius and linear wear of the cutting edge. The paper employs method of least squares and variance analysis in application of the Minitab software to determine regression equations for relation of the tooltip radius and linear wear to the relative cutting length. The ultimate goal is to predict the life of cutting tool when milling tropical wood.

Published: November 2021

The normal stress of each layer of the laminate composite material will undergo complex changes after normal compression, and shear stress will also appear between the layers. In order to explore the distribution laws of normal stress and shear stress, this paper uses Hooke's law and the equilibrium condition of force to carry out mathematical derivation, the analytical formulas for normal stress and shear stress are obtained, and their respective maximum values ​​are given. Studies have shown that the maximum normal stress occurs at the center of the laminate, and its value is proportional to the external load, and is also closely related to the length, width, thickness, elastic modulus of the cementing agent, elastic modulus and Poisson’s ratio of the laminate; The maximum shear stress occurs at the four corners of the laminate, and its value is proportional to the external load and the shear modulus of the cementing agent, inversely proportional to the thickness of the cementing agent layer, and its value is also closely related to the length, width, elastic modulus and Poisson's ratio of the laminate. The analytical formulas for normal stress and interlayer shear stress is helpful to deepen the understanding of the internal force distribution law of laminated plates, and the maximum value calculation formula can greatly facilitate the calculation of strength.

Background: Carious lesions can occur on the proximal surfaces of the posterior teeth. Streptococcus mutans and Streptococcus sobrinus, are the main acidogenic bacteria that are commonly associated to dental caries. Interproximal cleaning is an important form of oral self-care habits, considering such areas of the dentition are easily affected by caries. Accordingly, dental floss has been used as an additional tool to enhance the quality of the cleaning process. It is reasonable that dental flossing should reduce interproximal caries risk because it is capable of removing parts of the interproximal plaque. The aim of this study was to evaluate the antibacterial activity of gold nanoparticle (AuNPs), when coated on unwaxed dental floss.Methods: Streptococcus mutans and Streptococcus sobrinus were cultured in Brain Heart Infusion (BHI) agar. Broth microdilution method was used to determine the minimum inhibitory concentrations (MICs) and the minimum bactericidal concentrations (MBCs) of the AuNPs with subcultures so obtained. Then, the bacteria were grown and spread on blood agar on which identical lengths (20mm) of unwaxed dental floss coated with gold nanoparticles (AuNPs) at concentration of 0.05, 0.1, and 0.5 mg/mL were placed. Control included untreated unwaxed dental floss and unwaxed dental floss with 0.2% Chlorhexidine (CHX). Five randomized sites of the inhibition zones were measured in millimeters in each concentration per floss. Means ± S.D. of the inhibition zones were calculated.Results: The MIC and MBC of AuNPs against S. sobrinus and S. mutans were 0.5 μg/mL and 1.0 μg/mL, respectively. The results indicated that gold nanoparticles (AuNPs) coated unwaxed dental floss, placed on blood agar with S. mutans and S. sobrinus demonstrated significant inhibition of bacterial growth. Gold nanoparticles (AuNPs) coated unwaxed dental floss at 0.05, 0.1, 0.5 mg/mL resulted in zones of inhibition ranging from 2.93 ± 0.30 mm to 4.71 ± 0.32 mm for S. sobrinus and 2.95 ± 1.73 mm to 5.18 ± 0.61 mm for S. mutans, respectively.Conclusion: Invitro study demonstrated that the AuNPs-coated unwaxed dental floss had antibacterial activities against cariogenic bacteria.

This study's goals are to fabricate and analyze the microstructure and optical properties of BT and Li-doped BT as the dependence of the Li concentrations (x) of 0.05, 0.1, and 0.15. The thin films of the BT and Li-doped BT have been successfully deposited on the quartz substrates by the sol-gel method. The microstructure and optical features were characterized via XRD and UV-Vis Spectrophotometer, respectively. The XRD patterns exhibit that the lattice parameter and cell volume of the Li-doped films are bigger than that of the BT due to the existence of Li doping in the BT host structure. Additionally, the tetragonality and crystallite size of all films decrease as the more Li number with the BLTO5 has the biggest lattice strain as compared to the others. Meanwhile, the optical characterization reveals that the transmittance spectra increase and the absorption edges shift to the shorter wavelengths as the addition of Li dopant indicating the bandgap values change. In contrast, the refractive index values of the films reduce by the more Li number.

Published: November 2021

An electrosparking experiment of ASP30 powder metallurgical steel was carried out through tool electrode forced cooling based on micro heat pipe bundle by using the semiconductor encapsulation mould. Results demonstrate that the micro groove formed among sintered copper fibers based on wick of micro heat pipe and the unique composite structure of the surface chopped morphology can not only increase capillary pressure of the wick, but also strengthen evaporation/condensation process at two ends of the micro heat pipe, and improve cooling effect of micro heat pipe to tool electrode significantly. Compared with traditional electrosparking, electrosparking of tool electrode forced cooling based on micro heat pipe bundle increases the inter-electrode cooling, chip removal and deionization of electrosparking and further lowers tool electrode loss by strengthening heat dissipation of tool electrode. Hence, it can improve stability of electrosparking, increase pulse utilization and increase the processing speed and processing surface quality significantly.

Acid mine drainage is characterized by low pH value, many types of heavy metals, high concentration of heavy metals and great environmental damage. Copper precipitation by sulfate reducing bacteria is a common method. In this experiment, the AMD after iron removal was treated by an upflow anaerobic bioreactor. The effects of HRT, carbon source type, carbon source dosage and reactor temperature on the operation of the reactor were studied. The optimum process parameters were determined: HRT was 12h, formic acid was used as carbon source and the dosage was 0.5g/L, and the temperature was 30 °C. Under the process conditions, the Cu concentration in the reactor effluent decreased to 0.043mg/L, and the recovery rate of Cu metal was 99.9%. The mechanism of copper deposition in the reactor was studied by characterization of the structure and morphology of the precipitated product and the analysis of the microbial community structure in the effluent of the reactor.
