Organic soil such as peat soil has a high organic content, compared with cohesive and cohesionless soil. The percentage of fiber content in peat soil shows the level degree of humification which is fibrous, hemic, and sapric. Organic and fibre content are two component properties that affect peat settlement due to its leading to extreme settlement issues for the foundation in long-terms. The purpose of this research is to identify the physical and mechanical properties of peat soil, as well as identify the displacement of bamboo Denrocalamus asper on peat settlement by applying continuous loading in physical modelling. Sample of peat from Kampung Parit Puteri Menangis, Benut, Johor. Sample preparations were divided into three parts which are physical properties (part 1), undisturbed samples were collected for moisture content, specific gravity, organic content, and fibre content. While mechanical properties (part 2), disturbed samples were collected for consolidation. As well as physical modelling (part 3) disturbed samples were collected for the displacement of settlement bamboo Dendrocalamus asper on peat soil. The outcomes of this research identified that the moisture content is 672%, specific gravity is 1.23, organic content is 88.34 – 96.19%, and fiber content is 38.1%. As well as the peat soil is categorized as H4 to H6 (Hemic). The outcomes for compressibility properties (Cc, Cv, and Cα) were determined as 0.13 to 1.54, 0.62 to 4.925, and 0.02 to 0.048 respectively. While for the outcome’s settlement bamboo Dendrocalamus asper on peat soil, the displacement decreased by 48 to 50% after applying a maximum load of 4 kg/cm2 in 2 hours. It can be concluded that the original peat soil needs to be treated to improve the settlement. The load applied on the peat soil affected the displacement of the foundation before collapse. The replacement with bamboo reinforcement on the peat reduces the displacement of settlement. The maximum settlement was decreased in a short period of 1 hour and 2 hours.

Published: July 2024

The deteriorating state of ecosystems poses risks for nature enthusiasts in forests and rivers. The hazardous headwater phenomenon, a frequent and potentially fatal occurrence, threatens human life and the environment. Recognizing the danger is challenging, as existing technologies focus on flow pattern analysis rather than identification. To address this gap, the Headwater Phenomenon Warning and Monitoring System, an IoT and mobile application, was developed. Integrating sensors like accelerometers, vibration, and rain detection, the system enables real-time monitoring and provides early warnings. The prototype contributes to early warning, flood forecast, hydrological research, climate impact assessment, disaster management, and environmental monitoring, aiding our understanding of climate change implications. The prototype underwent multiple DOE to validate sensor and communication system integrity and stability. Turbulence and vibration graphs were successfully recorded, enhancing hazard identification and real-time monitoring capabilities.

The present study aimed to investigate the mechanical properties of recycled Polyethylene Terephthalate (r-PET) and Polycarbonate (PC) composites, with the incorporation of Methylene Diphenyl Diisocyanate. The primary objective was to identify the optimal composition for achieving superior mechanical performance. The composition under examination comprises four ratios, namely r-PET/PC1 (20/80), r-PET/PC2 (40/60), r-PET/PC3 (60/40), and r-PET/PC4 (80/20), expressed as weight percentages. The concentration of MDI utilized in the experiment was maintained at a constant level of 0.9% based on weight. The r-PET/PC/MDI composite underwent blending using a Brabender Plastograph prior to being introduced into the injection moulding process for sample production. The mechanical properties can be ascertained through the analysis of data acquired through mechanical testing, encompassing Tensile tests, Flexural tests, and Impact tests. The findings indicate that there is an inverse relationship between the percentage of r-PET in the blend and the tensile strength, with an increase in r-PET resulting in a decrease in tensile strength. Conversely, there is a positive relationship between the percentage of r-PET and Young's modulus, with an increase in r-PET leading to an increase in Young's modulus. The flexural strength and flexural modulus exhibit variations as the r-PET content increases in the r-PET/PC/MDI blend. Lastly, it can be observed that the impact strength reduces as the proportion of r-PET in the blend increases. The findings of this experiment indicate that the composition of r-PET/PC1 yielded the most favourable results. The composition under investigation demonstrated the greatest recorded tensile strength, measuring 22.30 MPa, as well as the second highest flexural strength, measuring 119.77 MPa. However, the impact strength of r-PET/PC1 exhibited the greatest value compared to the other samples, measuring 0.32J. In summary, the findings indicate that the mechanical characteristics of the r-PET/PC/MDI mix can be improved through the optimization of PC content, hence enhancing the features of r-PET.

This study addresses common challenges in conventional home electricity usage, with a focus on safety concerns related to gas leakage. In many cases, current technology lacks immediate power usage tracking, and manual control of circuit breakers, sockets, and lamps proves challenging, especially when users are away. To overcome these issues, this project employs an ESP8266 Wi-Fi Shield Arduino as a microcontroller connected to sensors and a servo motor. In the proposed system, users can detect gas leakage, control lamp and socket activation, and manage the Residual Current Circuit Breaker (RCCB) with the servo motor by utilizing Blynk apps for monitoring. The main objective of this study is to design a centralized system that enables users to control and manage home electrical appliances via smartphone. The methodology involves developing a microcontroller program for the Cytron ESP8266 WiFi Shield, creating an auto-reclosure circuit breaker notification, and building a practical gas leakage detection prototype for household applications. Additionally, the system addresses lightning-induced overvoltage issues, analyzes nuisance tripping, and provides control over home appliance usage while effectively detecting hazardous gas leaks. The approach is based on Blynk and the ESP8266 Wi-Fi Shield Arduino by incorporating data from limit switch conditions, relay status, voltage sensors, current sensors, and power consumption. The results justify the servo's efficient performance, reliable relay operations, and precise gas sensor triggering. Despite slight variations in current and voltage values compared to the actual meter, the system offers a successful and systematic approach to enhancing home electricity management and safety.

Air pollution is a global issue causing 7 million deaths annually, primarily due to dangerous compounds and inhalable particles. The World Health Organization estimates that air pollution is a significant threat to human health and safety. The Internet of Things (IoT) is utilized in this research to analyse sensor data from various environmental monitoring devices. The objective is to build an IoT-based air quality system that assesses air quality conditions in specific areas and analyses air levels of various compounds. The study employs IoT technology to analyse data from various environmental sensors, aiming to create an IoT-based air quality system. The sensors include measuring NH, C6H6, VOCs (MQ135), CH4 (MQ5), and particle matter (PM2.5). The ESP32 microcontroller and thinger.io platform is used to develop the system. FastTree and Generalized Additive Model (GAM) are machine learning methods applied to predict and analyse air quality data. FastTree utilizes gradient-boosting to enhance accuracy, while GAM employs smooth parts, represented by splines, for relationship modelling. Evaluation metrics R2, RMSE, MSE, and MAE assess model performance, for MQ135 with FastTree outperforming GAM with an R2 of 91.91% compared to 78.05%. The IoT-based air quality system is user-friendly and effective, tracking harmful components against thresholds. Future work includes adding cameras and printed circuit boards for expanded analysis.

A nanostructured zinc oxide (ZnO) with different percentages of argon and oxygen gas flow rate was deposited on a silicon wafer by a simple hot tube thermal evaporation technique. The effect of different percentages of gas flow rate on the crystal structure, surface morphology and optical properties were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) and RAMAN spectroscopy, respectively. The changes of morphologies from FESEM were significant where the grown ZnO nanostructures show three different shapes which are nanotripods, nanoclusters and nanorods at 5%, 10% and 25% of oxygen gas, respectively. EDX results revealed that Zn and O elements have a major percentage in the sample indicating a composition has high purity of ZnO. XRD patterns displayed the most intense diffraction peak of ZnO at (101), which exhibited a single crystalline hexagonal structure with preferred growth orientation in the c-axis. RAMAN scattering study found that synthesized ZnO shows the high intensity of E2 mode and low intensity of E1 mode attributed to all the samples having good crystal quality containing fewer structural defects. In conclusion, the E15 sample with a 25% oxygen gas flow rate was selected as an optimum result for synthesizing a homogenous surface and high crystallinity of ZnO by using a hot tube thermal evaporation process. This work can enhance the development of ZnO production in various applications.

Vortex generator is a component that has a significant impact on aircraft performance. The function of the vortex generator is to create vortices that can optimize the aerodynamic performance of aircraft wings by avoiding air flow separation and increasing lift at high angle of attack. Vortex generator can provide increased lift during take-off and landing due to the increased wing angle of attack. Although the use of vortex generator can be carried out using an experimental approach, a computational fluid dynamic approach to determine the influence of geometric parameters and placement of the vortex generator needs to be carried out. The aim of this research is to determine the effect of parameters like placement on the wing chord, height of the boundary layer, length, shape, angle of incidence and distance between pairs on the lift and drag. The model used as a computational fluid dynamic calculation model is the Spalart Allmaras transient model. As a result, vortex generator does not always have a good effect on aerodynamics. All configurations have a negative influence on the lift and drag values, but the flow separation phenomenon can be reduced significantly. Of all the configurations, the best configuration is obtained by exhibiting an ogive shape, positioned at 13.8% of the chord length, set at a 13o angle of incidence. The vortex generator should have a height closely matching the boundary layer, with a length 6.5 times the height and a pair spacing of 6.7 times the height

Published: July 2024

This research aimed to develop a numerical solution to analyze the effects of solar radiation and nanoparticle shape factors on the flow of a hybrid nanofluid past a shrinking Darcy-Forchheimer porous medium. The base fluid chosen for this study is water (H2O), and the hybrid nanofluid consists of nanoparticles of silver (Ag) and titanium dioxide (TiO2) in four different shapes: bricks, cylinders, platelets, and blades. To account for solar radiation, the energy model incorporated a radiative heat flux, while the momentum problem considers the influence of a magnetic field. The application of an appropriate similarity transformation method converts the partial differential equations (PDEs) model into a system of nonlinear ordinary differential equations (ODEs). The mathematical model is solved using the shooting technique method and the bvp4c solver. The obtained results, along with the effects of the nanoparticle shape factor, solar radiation parameter, shrinking parameter, Darcy-Forchheimer number, and nanofluid volume fraction, are visually presented through figures and tables. It is worth noting that, in our numerical results, we observed the presence of dual solutions when λ < 0. Our findings indicate that the thermal transmittance increases with an increase in the nanoparticle shape factor and solar radiative parameter. Additionally, we observed an escalation in the velocity distribution in relation to the shrinking parameter and nanofluid volume fraction. Before reaching the two solutions, a flow stability analysis revealed that the first branch appears to be the most stable. Overall, these findings provide valuable insights into the behaviour of hybrid nanofluid flow in the presence of solar radiation and porous media.

Multi-environment yield trials and multi-trait stability analyses are essential to identify the superior genotype. The aim of this research was to assess the adaptation and stability of rice genotypes using additive main effect and multiplicative interaction (AMMI) and genotype plus genotype by environment (GGE) biplot analysis and multi-trait stability index (MTSI). In this study, 20 rice genotypes were evaluated for three seasons at the same location during 2020–21. Based on AMMI analysis, the genotypes G22 (Vandana), G32 (IC-0098989), G34 (IC-0135769), G60 (ADT 36), G61 (ADT 37), and G64 (ADT 45) were found to have high yield and were more stable. GGE analysis revealed that the high-yielding and stable genotypes were G22 (Vandana), G34 (IC-0135769), G60 (ADT 36), and G64 (ADT 45). The genotypes G65 (ADT 48), G60 (ADT 36), G38 (IC-0135529), and G33 (IC-0124198) were observed to be stable based on the Multi Trait Stability Index (MTSI). Based on the above, G60 (ADT 36) could be concluded as stable across all seasons, not only based on yield but also other important agronomic traits.

Este texto analisa questões relacionadas à coordenação federativa do Sistema Único de Saúde (SUS), com repercussões negativas sobre o acesso a bens e serviços públicos de saúde, visando à identificação e recomendação de medidas que contribuam para a solução gradual das dificuldades de acesso. Seguindo a metodologia de análise de políticas públicas, após a definição do problema público como dificuldade de acesso tempestivo, efetivo e equitativo a bens e serviços públicos de saúde foi elaborada uma árvore do problema e várias causas e consequências foram identificadas. A causa escolhida para intervenção neste estudo é a coordenação federativa insuficiente, também considerada um problema estrutural do SUS. Uma das formas de minorar o problema de acesso tempestivo e equitativo à atenção à saúde é aumentar a disponibilidade de bens e serviços de saúde nas áreas mais carentes. Mas isso deve ser feito da forma mais efetiva, dentro dos princípios e das diretrizes do SUS, com base em uma ação cooperativa entre os entes federados. Assim, ainda que existam outras formas de expandir a oferta pública de bens e serviços de saúde, entende-se que, em situações específicas, o consórcio intergovernamental é uma opção que não pode ser descartada. A proposta preliminar deste texto foi analisada em um fórum de política pública com a participação de pesquisadores, técnicos e gestores do SUS, com reconhecido conhecimento sobre o tema. As contribuições dos participantes do fórum foram incluídas no texto e o resumo das discussões consta nos apêndices.

Magnetic reconnection and current disruption are two key processes in driving energy conversion and dissipation in planetary magnetospheres. At the Earth, the two processes usually occur at different locations: the current disruption process occurs more frequently in the near-Earth magnetotail ∼10 R
E, while the magnetotail reconnection process is expected to take place in the more distant region where the current sheet is thinner. Occasionally, under very intense solar wind perturbations, reconnection could be located closer to the Earth where current disruption processes usually operate. But it is unclear what the situation is at giant planets, in which the plasma environment is very different from the Earth. In this study, we investigate a middle-Jupiter reconnection event at ∼43 R
J. During the event, the inferred integrated cross-field currents were substantially reduced, which we argue is a signature of current disruption. In this case, we suggest that magnetic reconnection could be colocated with a current disruption process in the Jovian magnetosphere, which is roughly analogous to the situation in the extremely perturbed Earth’s magnetosphere.
Determination of the Abundance of Mercury from the Hg ii Line at 5677.10 Å in Late B-type Stars. IV. HD 149121 (28 Her) and HD 178065
Authors: Monier Richard
Published: July 2024

The weak line of Hg ii located at 5677.10 Å is used to measure the mercury abundance in two HgMn stars, HD 149121 (28 Her) and HD 178065. This line is detected at 3σ above the noise in the adjacent continuum in both stars. The synthesis of this line confirms a large overabundance of mercury, about +4.57 dex in HD 149121, and +3.70 dex in HD 178065, which is less than the excesses derived from the 3983.93 Å line in earlier studies. The presence of previously reported weak emission lines of Ti ii at 6106.50 Å and of Cr ii at 6158.62 and 6182.30 Å in the spectrum of HD 178065 is confirmed. The synthesis of other lines close to the Hg ii line yields estimates of the abundance deficiencies or excesses relative to solar abundances. Oxygen has a solar abundance (0.00 dex), silicon is deficient (−0.48 dex), iron also (−0.22 dex) and chromium is overabundant in HD 178065.

Gaia DR3 data of 52 high galactic latitude Hα emission stars selected from the paper of Stephenson are analyzed. Ten new variable stars and eight new high velocity stars have been found. Details of six post-AGB stars and several other interesting stars are discussed. Many of the stars presented in this paper have Gaia DR3 light curves and spectra. A detailed study of these 52 stars is needed to derive their chemical composition and to further understand their binarity, circumstellar matter and evolutionary status. The astrophysical parameters from the Gaia DR3 data reveal several hot (OBA) and several F and G-type stars in this sample. Some of them are metal-poor stars.

Avec Myriam David, prendre soin d’un enfant placé. « Faire table rase de l’idée qu’il existe des placements sociaux simples »
Authors: Detry Laurette
Published: July 2024

Les fractures d’un parcours de vie, aussi précoces soient-elles, s’expriment à travers les relations. Elles résonnent immanquablement dans les détails de l’éducation des actions de la vie quotidienne. Prendre soin de celles-ci et s’y pencher vraiment, c’est proposer une fonction phorique à un enfant. Y associer d’autres outils (art, psychologie, nature, pédagogie, sport…), c’est reconnaître que prendre soin est pluriel entre singularité et groupe. Cette possibilité offre un tressage précieux entre continuité physique et continuité psychique articulées à une cohérence institutionnelle qui a parfois ses limites.

Giuseppe Maffei : anomalie ou articulation d’une pensée jungienne italienne ?
Authors: Carrara Stefano
Published: July 2024

L’auteur expose la pensée de Giuseppe Maffei, psychanalyste jungien disparu depuis peu qui, avec ses écrits et son activité de formateur, de superviseur et de créateur de liens et d’échanges culturels, a contribué d’une manière significative au développement de la psychologie analytique en Italie. Le cadre est constitué par le contexte de l’histoire et des particularités du mouvement jungien italien, avec en arrière-plan les rapports entre la psychologie analytique et la psychanalyse à l’enseigne du pluralisme présent dans les conceptions de Jung. La lecture de Jung de la part de Maffei était fortement enracinée dans la clinique, à partir de celle des psychoses, mais privée de toute approche de type « scolaire » ou hypostasiante ; chez lui, le dialogue avec la psychanalyse freudienne et postfreudienne était constant, sans jamais par ailleurs s’aligner sur elle. Tout « savoir » avait pour finalité chez lui la rencontre avec la réalité psychique de l’autre, et cela d’une manière profondément jungienne.
Violence et métamorphose dans la chrysalide nationaliste : mue et nécessaire déconstruction
Authors: Bates Carolyn , Braun Sophie
Published: July 2024

À travers une imagination active, l’auteure raconte le parcours d’une cure analytique de Démocratie encerclée par le nationalisme et devant résister aux nombreuses attaques portées contre elle. Elle cherche à retrouver le lien avec les origines tribales de sa mère pour enfin sortir d’un patriarcat étouffant et paralysant et que de la chrysalide sorte une identité plurielle et vivante.
L’impact démographique devenu non négligeable de la procréation médicalement assistée en France
Authors: de La Rochebrochard Élise
Published: July 2024

Depuis 30 ans, le recours à la procréation médicale assistée (PMA) a progressé de manière remarquablement linéaire, avec désormais 1 enfant sur 29 conçu par PMA. Le poids de la PMA dans la natalité française pourrait encore progresser dans les prochaines décennies avec une augmentation de l’infertilité dans la population sous l’effet combiné de l’augmentation de l’âge à la parentalité et d’une exposition grandissante aux perturbateurs endocriniens qui pourraient altérer la fertilité. Face à ces enjeux, de premières propositions ont été faites pour développer une stratégie nationale de lutte contre l’infertilité.
Entre la recherche d’un idéal et la réalité de la rencontre avec un sujet
Authors: Le Berre Rozenn
Published: July 2024

Nous interrogerons ici les enjeux éthiques et philosophiques d’un dialogue entre idéal et réalité dans le contexte des soins, en se concentrant en particulier sur le moment de la rencontre. À quelles conditions la rencontre intersubjective peut-elle survenir ? L’hypothèse que nous soutiendrons est que cette rencontre entre des sujets au cœur de la relation soignante est conditionnée par une dynamique complexe dont la fonction de l’idéal est l’enjeu.

Published: July 2024

For any positive integer $ \mathrm{n} $, let $ \mathrm{M_{p}} $ contain the prime numbers less than $ \mathrm{n} $. Assuming $ \mathrm{M_{p}} $ as the set of moduli, we draw a graph with the vertex set $ \{1, 2, 3, \cdots, \mathrm{n}\} $, and an edge will be built between the vertices $ \mathrm{p} $ and $ \mathrm{q} $ if and only if $ \mathrm{p}\equiv (\mathrm{q}\; mod\; \mathrm{m}) $ for some $ \mathrm{m}\in $ $ \mathrm{M_{p}}. $ We call this graph a prime congruence simple graph and label this graph as $ \mathrm{G}(\mathrm{n}, \mathrm{M}_{p}) $. The objective of this work is to characterize prime congruence simple graphs, and afterwards, by utilizing these graphs, solutions to the system of linear congruences are suggested and demonstrated by applying modular arithmetic. It is shown that this graph is always a connected graph. The generalized formulae for vertex degrees, size, chromatic number, domination number, clique number, and eccentricity of the prime congruence simple graphs are proposed and proved. Also, independence numbers as well as a covering number for the proposed graph through vertices and edges are evaluated. Lastly, as an application of prime congruence simple graphs, the solution of a system of linear congruences is discussed in terms of the degrees of the vertices.

Drought stress represents a major constraint with significant impacts on wheat crop globally. The use of plant growth-promoting bacteria (PGPB) has emerged as a promising strategy to alleviate the detrimental impacts of water stress and enhance plant development. We investigated 24 strains from diverse ecosystems, assessed for PGP traits and tolerance ability to abiotic stresses (drought, salinity, temperature, pH, heavy metals, pollutants, herbicides, and fungicides). The most effective bacterial strains Providencia vermicola ME1, Pantoea agglomerans Pa, Pseudomonas knackmussi MR6, and Bacillus sp D13 were chosen. Furthermore, these strains exhibited PGP activities under osmotic stress (0, 10, 20, and 30% PEG-6000). The impact of these osmotolerant PGPBs on wheat (Triticum durum L.) growth under drought stress was assessed at two plant growth stages. In an in vitro wheat seed germination experiment, bacterial inoculation significantly enhanced germination parameters. In pot experiments, the potential of these bacteria was evaluated in wheat plants under three treatments: Well-watered (100% field capacity), moderate stress (50% FC), and severe stress (25% FC). Results showed a significant decline in wheat growth parameters under increasing water stress for uninoculated seedlings. In contrast, bacterial inoculation mitigated these adverse effects, significantly improving morphological parameters and chlorophyll pigment contents under the stress conditions. While malondialdehyde (lipid peroxidation) and proline contents increased significantly with drought intensity, they decreased after bacterial inoculation. The antioxidant enzyme activities (GPX, CAT, and SOD) in plants decreased after bacterial inoculation. The increased root colonization capacity observed under water stress was attributed to their ability to favorable adaptations in a stressful environment. This study highlighted the potential of selected PGPB to alleviate water stress effects on wheat, promoting practical applications aimed at enhancing crop resilience under conditions of water shortage.
Numerical analysis of stretching/shrinking fully wet trapezoidal fin

Published: July 2024

The purpose of fins or extended surfaces is to increase the dissipation of heat from hot sources into their surroundings. Fins like annular fins, longitudinal fins, porous fins, and radial fins are used on the surface of equipments to enhance the rate of heat transfer. There are many applications of fins, including superheaters, refrigeration, automobile parts, combustion engines, electrical equipment, solar panels, and computer CPUs. Based on a wide range of applications, the effects of stretching/shrinking on a fully wet trapezoidal fin with internal heat generation is investigated. The shooting approach is used to calculate the trapezoidal fin's thermal profile, tip temperature, and efficiency. It is observed that with an increase in the shrinking and wet parameter, the temperature distribution decreases and efficiency increases. On the other hand, when stretching increases, the temperature distribution increases and efficiency diminishes. Using the computed results, it is concluded that shrinking trapezoidal fins improves the effectiveness and performance of the system.
¿Yma Súmac y/o Pastorita Huaracina? Límites y posibilidades de las políticas culturales de José María Arguedas
Authors: Suárez Trejo Javier Teofilo
Published: July 2024

El presente artículo es una primera aproximación a los límites y posibilidades de la comprensión arguediana de las políticas culturales, cuyo fin es mostrar una faceta poco estudiada del escritor y antropólogo peruano. En la primera parte, a través del análisis de diversas cartas, se ofrece un retrato de Arguedas como agudo crítico educativo y proactivo director de la Casa de la Cultura. En la segunda, se describe la noción de «Arte Andino» de Arguedas, y su impacto en el diseño de políticas culturales, a partir del análisis de la dicotomía entre el retablo «auténtico» de Joaquín López Antay y el «espectacular» de Jesús Urbano Rojas. Asimismo, se rastrean estos juicios hasta la década de 1940 en la que una dura crítica a Yma Súmac y a su productor, el musicólogo y compositor Moisés Vivanco, revela cómo este requerimiento de autenticidad permea el discurso arguediano hasta la década de 1960. Finalmente, se analiza cómo, a partir de la segunda mitad de los años sesenta, esta visión dicotómica se flexibiliza debido a la aparición de «instituciones nuevas» que no son sino iniciativas culturales y populares implementadas por los migrantes andinos en las ciudades costeñas del Perú.

During last decade, Internet and related web technology development enabled the arising of e-learning services and made distant learning a reality. As traditional face to face classroom became virtual classroom through Internet, traditional laboratories found their image in Electronic Laboratories (ELABs). These ones enable learners to train themselves on remote real or virtual systems. They represent essential components in e-learning environments, especially in scientific and technical disciplines.
In this context, AIP-Primeca RAO is a pool of resources and competencies about industrial topics for many universities in Rhône-Alpes french Region. Due to the constraints inherent in using heavy and shared industrial resources, AIP is setting up new laboratories related to automation as both local and distant resources. After recalling the global context of e-laboratories, this paper describes this platform. It evokes first returns of use and it details evolutions to come.

Published: July 2024

Over the last decade, there has been a move towards using remote laboratories in engineering education. The majority of these laboratories are static, involving limited user-controlled mechanical movements. The University of South Australia has developed such a laboratory, called NetLab that has been successfully utilized for teaching both on-campus and transnational programs in electrical and electronics engineering. Following this success, we are now developing a remote laboratory for microelectronic fabrication, MEFLab. The first stage of the development is a remote laboratory for visual inspection and testing of electronic circuits directly on the silicon wafer under a microscope which is normally conducted in a cleanroom. The major challenge of this project is the accurate positioning of micro-probes remotely over the internet. This paper presents the details of the setup of this new remote laboratory, with a particular emphasis on the development of the hardware, software and graphical user interface.

Automatic Evaluation of Studentâ??s Performance in Online Laboratories
Authors: Maiti Ananda
Published: July 2024

Online laboratories are increasingly being deployed in traditional on-campus as well as Web-based distance-learning courses (distance education) around the world. An online laboratory generally will consist of several experiments (a module). Evaluation of studentâ??s performance and grading in laboratory courses involves quiz/viva-voce examinations, checking of experimental data and the submitted laboratory report. The students submit online laboratory report containing experimental data, interpretation, and extracted parameters. The submitted values are automatically compared and graded, with the grading criteria decided by the instructor along with the option of awarding credit for the particular experiment session. In this paper, we describe in detail a proposal on the design and prototype implementation of automatic student performance evaluation and grading system in NetLAB laboratory management system (LMS) currently in use for undergraduate and graduate online laboratories at IIT Kharagpur.
Intérim : troubles dans la prévention

Published: July 2024

La santé au travail des salariés intérimaires fait l’objet d’un suivi particulier, le problème de leur sur-accidentalité étant régulièrement mis à l’agenda. Pourtant, ce constat dissimule les lacunes dans l’objectivation et la prise en charge des expositions professionnelles des intérimaires. Il s’agit moins d’une ignorance que de dispositifs de suivi qui peinent à déclencher et à équiper l’action de prévention. L’analyse porte sur trois dispositifs institués de suivi des risques professionnels : l’enregistrement administratif des accidents du travail et des maladies professionnelles par la Caisse nationale de l’assurance maladie des travailleurs salariés (Cnam-TS), le suivi de l’état de santé des intérimaires par les services de santé au travail et l’évaluation et la prévention des risques organisées par les entreprises de travail temporaire. Pour chacun de ces dispositifs, sont analysés les initiatives, les efforts et les arguments déployés par celles et ceux qui sont chargé·es de ces questions et qui se trouvent ainsi placé·es en difficulté pour agir.
