Risques, sécurité des salariés et diligences de l’employeur
Authors: Pereira Brigitte
Published: September 2021

Cet article traite de l’évolution des décisions de justice sur l’obligation de sécurité de l’employeur de 2000 à 2020. Cette évolution impacte le champ de la gestion des risques. D’une obligation de résultat à une obligation de diligence, l’employeur doit mettre en place les moyens pour assurer la sécurité des salariés. Il est incité à développer les diligences de sécurité en prenant en compte les décisions de justice préconisant la participation collective à l’évaluation des risques. On assiste alors à une mise en tension des deux champs (sciences de gestion et droit), ce qui conduit à des incidences managériales significatives. Cela est particulièrement remarquable lorsqu’on s’intéresse au risque actuel de contamination des salariés au SARS-CoV-2.

Published: September 2021

A first Russian isolate of the anthracnose fruit rot-causing Colletotrichum fungus was obtained from blackcur rant of Moscow and Bryansk regions. In the Bryansk Region, Colletotrichum sp. was isolated from berries of ten blackcur­ rant varieties, including Bagira, Mriya, Mriya-5, Selechenskaya, Litvinovskaya, Nadina, Nara, Yadrenaya, Sofievskaya and Ben Hopen. The Colletotrichum genus fungi were observed on Sadko and Bryanskiy Agat blackcurrants in the Moscow Region and on Dobrynya and Yadrenaya — at the Timiryazev Academy station in Moscow. Colletotrichum species endure mainly on mummified persistent blackcurrant berries in a viable form for over two years. Saprotrophic yeast-like fungiof the genera Cryptococcus and Rhodotorula largely compound the blackcurrant-infesting micromycete flora, aside to the hyphomycete Auerobasidium pullans and related genera Penicillium, Fusarium, Alternaria and Cladosporium. Some of these fungi are antagonistic to suppress the Colletotrichum genus fungi. A standard PCR sequencing was employed for the species identification of two Colletotrichum isolates from Bryansk and Moscow regions. Both isolates were found to represent the same species Colletotrichum fioriniae Marcelino & Gouli.
Applications of Mobile Learning and Transactional Distance Theory in the Context of Higher Education during COVID-19 Pandemic
Authors: Mubayrik Haifa F. Bin
Published: September 2021

ABSTRACT Mobile learning, which can be performed through numerous applications that run on smartphones, personal digital assistants, and other devices, has played a major role in education, especially during under the restrictive conditions due to the COVID-19 pandemic. This paper is a review of literature of mobile learning efficiency in education. Some application of m-learning in education have shown extensive success. Mobile learning could meet with success in a suitable learning environment. The recently developed transactional distance theory focuses on three elements in the connection and involvement in the distance education environment, namely, the teacher, the student, and dialogue. The core of that theory is investigating the ways that the learner can progress to becoming a self-directed learner with the support of the teacher. Though there are advantages to m-learning, there are some disadvantages of m-learning such as technical, physical and health issues
New Manufacturing Process and Product Developments in Metal Forming Industry Using Finite Element Modelling and Optimization Techniques
Authors: Nguyen Van Bac , English Martin
Published: September 2021

The objective of this paper is to outline a practical approach using numerical modelling and optimization techniques for process and product developments in metal cold rolled forming industry. The optimum economic viability in manufacturing industry requires a minimization of the amount of material used while the structural performance of a cold roll formed product relies on maintaining the stiffness and strength of the section in applications. This leads to the development of new cold forming processes and alternative cold roll formed profiles searching for the optimal profile. In this paper, a Finite Element modelling approach was utilized to simulating complicated manufacturing process and products and optimization techniques including Design Of Experiments was used to optimize the shape design of the end products to obtain lighter products while maintaining the product strength. These developments were illustrated through two case studies of Hadley Industries plc which included (1) numerical modelling of a novel Ultra STEEL® cold roll forming process, and (2) optimization of cold roll forming sections.
An Investigation into the Exploratory Use of Additive Manufacturing in Weir Design and Open Channel Flow
Authors: Benham Robert , Rehman Fayyaz
Published: September 2021

Additive Manufacturing (AM) offers a range of possibilities in fluid flow research. An existing 2.5 m open channel fluid flow experiment contains a set of standard weirs which are limited in design. This research will compare experimental AM weirs (e.g. labyrinth, piano, catenary), that would not be possible on some laser-cut polymer or machined aluminium weirs. Due to the bespoke complex nature of weirs’ design other manufacturing methods would be too expensive and impossible to use. AM technology allows a cost-effective solution for progressive design modifications to be implemented throughout investigations. This paper will highlight comparisons made between a range of AM produced weirs in terms of flow rate, fluid velocity profile, water level height and discharge coefficient. Computation fluid dynamic modelling (CFD) will also be used to verify, analyse, and compare results. Based on the experimental results and verification, the paper will also discuss the suitability of application of AM techniques in fluid flow analysis.

Authors: Wang Chang Jiang , Hazlehurst Kevin , Arjunan Arun , Shen Lida
Published: September 2021

Open and closed porous structures with lattice and honeycomb geometry can be built using laser powder bed fusion additive manufacturing processes. The porous structures can be used to tailor the mechanical properties of a component or provide other functionality, such as for bone ingrowth in medical implants. Porous structures were created and analysed in this paper both physically and using finite element modelling. It was found that the accuracy of the built parts was reasonable and within the manufacturing processes general tolerance of +/- 50 μm. However, it was noticeable that the corners of the square shape pores were naturally filleted by the manufacturing process. The finite element model was developed using ANSYS software, stress concentrations were observed in the porous structures under loading. In addition to this, fragments of the material were present on the internal surfaces of the pores, which were formed from partially melted powder particles.

Authors: Li Nanya , Link Guido , Ma Junhui , Jelonnek John
Published: September 2021

3D printing of lightweight continuous carbon fiber reinforced plastics (CCFRP) in three dimensions changes the traditional composite manufacturing processes. The continuous carbon fibers reinforced plastic filament can be printed along the load transmission path and significantly improve the strength of composite structures. Compared to the three-axis computer numerical controlled (CNC) machine based printing process, industrial robots provide the possibility to manufacture complex, spatial and large-scale composite structures. Here, the concept to use multi-robot to print complex spatial CCFRP components simultaneously has been presented. More than one 6 degrees of freedom industrial robots can cooperate with each other and solve the contradiction between structural complexity and printing reachability. During the printing process, the deformation of composite structures may happen, especially for the self-supporting components. Thus, in this paper, a Light Detection and Ranging (LiDAR) method is introduced to detect the deformation of printed composite structure and the movements of two UR robots. To obtain the point clouds of the printed structure, a LiDAR camera D435i has been installed on one robot. A new approach by combining coordinate transformation and iterative-closest-point (ICP) algorithm has been developed to merge the point clouds collected from different shooting angles of the camera.
Characterization of Titanium Metal Matrix Composites (Ti-MMC) Made Using Different Manufacturing Routes
Authors: Sanguigno Luigi , Lepore Marcello Antonio , Maligno Angelo Rosario
Published: September 2021

The mechanical and morphological properties of the unidirectional metal matrix composite (MMC) in titanium alloy reinforced with continuous silicon carbide (SiC) fibres are investigated. The lay-up manufacturing process known as the Foil / Fibre (FF) lay-up was compared with the matrix-coated-fibre (CF) method which promises a better final shape of the reinforcing fibre net. Tensile tests were performed to measure mechanical performance of the manufactured MMCs both longitudinally and transversely respect to the direction of SiC fibres. Elastic behaviour of the investigated MMCs was assumed orthotropic and related to mechanical properties and spatial distribution of the MMC constituents: SiC fibres and Titanium (Ti) matrix. This was achieved using micromechanical modelling based on Finite Element (FE) calculations. FE micromechanical modelling was carried out on the Representative Elementary Volume (REV) of the MMC microstructure resolved by non-destructive analysis such as X-Ray tomography. The analysis carried out highlighted and justified mechanical performance difference between composite laminates containing the same amount of SiC reinforcement fibres for unit of volume but made following different manufacturing routes. To compute overall orthotropic behaviour of the MMC laminate, each constituent was assumed as an elastic isotropic heterogeneity during the averaging. This simplify assumption was validated by comparison with experimental data during the mechanical characterization of the investigated MMC composites.
Creep-Fatigue Behaviours of Sn-Ag-Cu Solder Joints in Microelectronics Applications

Published: September 2021

Electronic manufacturing is one of the dynamic industries in the world in terms of leading technological advancements. Electronic assembly’s heart lies the ‘soldering technology’ and the ‘solder joints’ between electronic components and substrate. During the operation of electronic products, solder joints experience harsh environmental conditions in terms of cyclic change of temperature and vibration and exposure to moisture and chemicals. Due to the cyclic application of loads and higher operational temperature, solder joints fail primarily through creep and fatigue failures. This paper presents the creep-fatigue behaviours of solder joints in a ball grid array (BGA) soldered on a printed circuit board (PCB). Using finite element (FE) simulation, the solder joints were subjected to thermal cycling and isothermal ageing. Accelerated thermal cycling (ATC) was carried out using a temperate range from 40°C to 150°C, and isothermal ageing was done at −40, 25, 75 and 150°C temperatures for 45 days (64,800 mins). The solders studied are lead-based eutectic Sn63Pb37 and lead-free SAC305, SAC387, SAC396 and SAC405. The results were analysed using the failure criterion of equivalent stress, strain rate, deformation rate, and the solders’ strain energy density. The SAC405 and SAC396 have the least stress magnitude, strain rate, deformation rate, and strain energy density damage than the lead-based eutectic Sn63Pb37 solder; they have the highest fatigue lives based on the damage mechanisms. This research provides a technique for determining the preventive maintenance time of BGA components in mission-critical systems. Furthermore, it proposes developing a new life prediction model based on a combination of the damage parameters for improved prediction.

Published: September 2021

This paper investigates the use of the discrete wavelet transform (DWT) and Fast Fourier Transform (FFT) to improve the quality of extracted features for machine learning. The case study in this paper is detecting the health state of the ballscrew of a gantry type machine tool. For the implementation of the algorithm for feature extraction, wavelet is first applied to the data, followed by FFT and then useful features are extracted from the resultant signal. The extracted features were then used in various machine learning algorithms like decision tree, K-nearest neighbour (KNN) and support vector machine (SVM) for binary classification of the ballscrew state. The result shows significant improvement in the classification accuracy after the wavelet transform and FFT has been performed on the data.

A pharmacokinetic study of the absorption into the bloodstream, bioavailability and excretion of Gamavit from the body after intramuscular administration to laboratory mini-pigs was conducted. Quantitative determination was carried out by HPLC using a fluorimetric detector, for which Gamavit was labeled with Cy5 dye, which was then used for mini-pigs inoculation. The developed methods for determining Gamavit in the blood and feces were validated according to the following validation parameters: selectivity, calibration curve, accuracy, precision, limit of quantitative determination, sample transfer, and sample stability. The confirmed analytical range of the method for Gamavit detection in blood plasma and feces was 1.00…50.0 mcg/ml. Maximum concentration of Gamavit in the blood of mini-pigs after a single intramuscular injection was 30.97 mcg/ml and was reached on average 15 minutes after administration. 24 hours following administration, Gamavit was still detected in the blood in insignificant amounts. The average half-life of Gamavit in the blood is 8.64±3.50 hours. After administration at a dose of 0.1 ml/kg, the clearance of the drug is 1.27 l/kg * h, the excretion rate at an effective concentration of 30 mg/l is 38 mg/kg*h, and the maintenance dose when using the drug 1 time a day is 0.9…1.0 ml. The detection of the label in the feces of the studied animals indicates that one of the ways Gamavit removal is excretion with the help of bile acids, as well as partial excretion with feces.

The subject of the study is the process of mapping the construction of point clouds of technical systems using the algorithm of the nearest points. The goal is to minimize the alignment criterion by converting a set of cloud points Y into a set of cloud points X in a software product that uses an iterative closest point (ICP) algorithm. Objectives: to analyze the properties of input images that contain point clouds; to review the algorithms for identifying and comparing key points; implement a cloud comparison algorithm using the ISR algorithm; consider an example of the algorithm for estimating the approximate values of the elements of mutual orientation; implement software that allows you to compare files that contain point clouds and draw conclusions about the possibility of comparing them. The methods used are: search for points using the algorithm of iterative nearest points, the algorithm for estimating the approximate values of the elements of mutual orientation, the method of algorithm theory for the analysis of file structures STL (standard template library - format template library) format. The following results were obtained. The choice of the ICP algorithm for the task of reconstruction of the object of technical systems is substantiated; the main features of the ISR algorithm are considered; the algorithm of comparison of key points, and also optimization that allows reducing criterion of combination at the reconstruction of three-dimensional objects of technical systems results. Conclusions. The study found that the iterative near-point algorithm is more detailed and accurate when modeling objects. At the same time, this method requires very accurate values and when calculating the degree of proximity, the complexity of calculation by this algorithm increases many times. Whereas the algorithm for estimating the approximate values of the elements of mutual orientation does not require information about the approximate orientation of the point clouds, which simplifies the work and reduces the simulation time. It was found that not all files are comparable. Therefore, the software is implemented, which gives an opinion on the possibility of comparing points in the proposed two files, which contain clouds of points in the structure of the STL format.
Lost in Lockdown?
Authors: Yu Jing
Published: September 2021

Due to uneven and hierarchical global context, the United States has been the world’s number one “Educational Hub” (Knight, 2011), leading the internationalization of higher education in multiple forms, the top priority of which lies in international student recruitment and enrollment. However, the COVID-19 pandemic has thoroughly disrupted the traditional mobility experience—a situation that has broader implications for the demographic landscape of US higher education. This article explores how COVID-19 and pandemic-related Sinophobia affect Chinese students’ perspectives on their educational decision-making. Based on Zoom interviews of a sample of 21 Chinese undergraduate students, this study demonstrates that despite the leading role of the US in international education, it is gradually losing appeal to Chinese students due to disillusionment with the romanticized imaginary of the US, anxiety about uncertain policies, and safety concerns. The unidirectional student mobility from mainland China to the US may be interrupted with Singapore and Hong Kong as the emerging destinations.

This qualitative study demonstrates how a culturally responsive teaching (CRT) approach builds the capacity of faculty and staff to create a social and emotional learning (SEL) environment that is conducive to success for international students. The researchers propose a CRT-SEL model to address the increasing needs of mid-sized universities with emerging international students. The findings from 14 faculty and staff participants point to professional development strategies that can help reduce or remove barriers for working with international students. This study highlights the need to build upon the CRT and SEL tenets and align them with the existing support networks within the mid-size higher education institutions for classroom learnings and off-campus activities to bolster international students’ overall success. The results also indicate the faculty and staff’s varying priorities and diverging trajectories.

When studying abroad, international exchange students generally establish a new social network abroad. However, how international exchange students develop their social networks over time remains a blind spot in the academic literature. In this paper, we therefore analyze the initial formation and development of such networks among six Dutch Erasmus+ students. Starting from homophily theory, we particularly focus on the factors that enable and restrain initial social network formation and interaction patterns. Methodologically, we rely on a longitudinal qualitative approach, whereby we repeatedly interviewed these six students over time. Our findings reveal the importance of three main contexts in the initial social network formation of Erasmus+ students, namely the pre-mobility phase, the living place, and the social space. These findings provide insights for practitioners on which contexts to focus on when developing strategies to foster the integration of international exchange students at host institutions.

Authors: Al-Jawaldeh Ayoub , Abul-Fadl Azza
Published: September 2021

Introduction: Early exclusive breastfeeding (EBF) without foods or formula milk (FM) is recommended for the first six months of life, for optimum growth and development. Aim: This study aims to review studies in Egypt on nutritional status of preschool children by type of feeding. Methods: A two staged study was done: First; research was obtained from the Egyptian university libraries consortium (www.eulc.edu) on overweight, obesity stunting, and wasting in preschool children. We filtered 18 thesis fitting the criteria of the study. Next, analysis was done to compare EBF versus FM. Results: Comparison of nutritional status of children aged 6–59 months among formula versus EBF was as follows: Overweight 5.4% versus 3.45%, obesity 13.8% versus 5.65%, stunting 21.6% versus 1.15%, and wasting 9.7% versus 0.85%, respectively. Obesity and overweight were higher in males, whereas stunting and wasting were higher in females irrespective of mode of feeding. Early and extended formula feeding, foods before 6 months of life, packed foods, canned drinks, and low activity are risk factors for obesity. Colostrum feeding, exclusive and longer duration of breastfeeding, healthy food intake, and fruits and vegetables are protective. Studies report that deficiency of micronutrients is common with obesity. Conclusions: Prolonged formula feeding and unhealthy food intake are risk factors for the emerging and growing problem of obesity. Policies and legislations are needed to encourage exclusive breastfeeding and control marketing of unhealthy foods.

Authors: Kumar A Prem , Gopalakrishnan Nair Sandesh
Published: September 2021

Fournier’s gangrene is a form of necrotizing fascitis with abrupt onset of rapidly fulminating genital gangrene of idiopathic origin and gangrene up to deep fascia. It occurs usually in patients with urogenital infections and comorbidities such as diabetes, immunosuppression, or even trauma. Here, we present one such case of an 86-year-old female presenting with a history of pain and purulent discharge from the perianal region for 5 days. On examination, a wound of 20 × 15 cm perineal region extending up to the gluteal region posteriorly and labia majora anteriorly. The patient was planned for debridement under spinal anesthesia on an emergency basis followed by regular dressing and antibiotic therapy. The peri-operative period was uneventful. Along with surgical management, the patient was managed medically by control of sugars, treating sepsis with appropriate antibiotics. The patient recovered from sepsis, and the wound showed granulation tissue after 1 week of serial debridement. The wound was closed with a skin graft at a later date. Fournier’s gangrene should be kept as a differential diagnosis in females with perineal abscesses or necrotizing fascitis in females.

Pembiasaan Pola Hidup Bersih dan Sehat Guna Memutus Mata Rantai Penularan Covid-19 adalah sebuah kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh Program Studi Broadband Multimedia Jurusan Teknik Elektro PNJ. Kegiatan ini dilandasi oleh kenyataan bahwa saat ini sedang mewabah virus Covid 19 yang sangat cepat penyebarannya. Salah satu penyebab cepatnya penyebaran adalah kebiasaan buruk di masyarakat kita yang belum terbiasa membiasakan Pola Hidup Bersih dan Sehat sebagaimana yang disyaratkan oleh Kementerian Kesehatan RI. Seperti diketahui, virus covid 19 dapat masuk dan menjangkiti manusia adalah melalui mulut, hidung dan mata. Anggota tubuh manusia yang sering menyentuh bagian tersebut adalah tangan. Covid 19 menyebar menjangkiti manusia melalui droplet yang dikeluarkan penderita ketika ia berbicara, bersin atau batuk. Droplet tersebut bisa saja menempel pada benda-benda yang sering disentuh oleh tangan. Tanpa mencuci, apabila tangan yang tidak sengaja menyentuh droplet tersebut digunakan untuk makan atau menyentuh bagian mulut, hidung dan mata, maka kemungkinan besar ia akan tertular. Oleh karena itu sangat perlu untuk dilakukan program pembiasaan pola hidup bersih dan sehat diantaranya adalah mencuci tangan dengan sabun. Untuk mendukung program tersebut maka pada kegiatan pengabdian kepada masyarakat kali ini telah dilakukan pelatihan pembuatan sabun cuci tangan, pemberian tempat cuci tangan portable beserta sabun cuci tangan serta pembagian masker.
O PAPEL DA EDUCAÇÃO PARA A EMERGÊNCIA DE UM HOMEM NOVO NA ÉPOCA DAS LUZES
Authors: Alves-Jesus Susana Mourato
Published: September 2021

Ao longo do século XVIII registou-se um amplo movimento de valorização da educação enquanto via para a construção de um homem novo. Na Europa das Luzes, a articulação entre educação e liberdade afirma-se como uma relação necessária (e.g. Émile, de Rousseau), bem como condição fundamental para o exercício do progresso e para a capacitação do homem enquanto ator histórico no alto quadro civilizacional da Europa coeva. Partindo do princípio de que todo o homem seria dotado de razão em igualdade de circunstâncias, uma das pedras de toque da filosofia das Luzes passou precisamente pela necessidade de reforço da educação no quadro das modernas sociedades ocidentais, com vista à emancipação dos homens face ao paradigma dos Antigos. A presente proposta explora esta tendência de valorização da educação no âmbito do pensamento português da época. Destacaremos alguns autores cuja reflexão ajudou à construção desse olhar sobre a educação, enquanto meio fundamental para a implementação de uma nova sociedade e de um renovado sentido político. Articularemos ainda esses antecedentes teóricos com as amplas reformas pombalinas do ensino, que intentaram em certa medida, ainda que sob o signo das suas idiossincrasias, afirmar o sentido racionalizante e modernizante que os ideais educativo-pedagógicos da época postulavam.Palavras-chave: Educação.

O COTIDIANO MACABRO

Este trabalho se propõe a analisar a composição do terror no conto “El chico sucio” (2016), de Mariana Enríquez. Partindo da ideia de que essa narrativa da autora argentina traz em sua estrutura procedimentos narrativos do gótico-terror-horror atrelados ao político-social, buscaremos refletir sobre como a conjunção miséria, violência e crenças populares contribui para a instauração de uma atmosfera inquietante de violência-terror-horror, desencadeando na protagonista uma pluralidade de medos que a leva ao limite. Para tanto, contamos com o apoio teórico de estudiosos como, por exemplo, Pampa Arán, Aparecido Donizete Rossi, Werner Mackenbach, Alexandra Ortiz Wallner e Karl Schøllhammer. Almejamos, com isso, iluminar perspectivas interpretativas sobre a mencionada obra de Mariana Enríquez.Palavras-chave: Terror. Horror. Violência. Medo. Insólito.
