ABSTRACT

FORGOTTEN INTRABRONCHIAL LARGE FOREIGN BODY: CASE REPORT

Background: Airway foreign bodies are objects lodged in the airways from the larynx to the segmental bronchi. It is a typical emergency in children, rarely seen in adults, and diagnosis can be delayed in the elderly. Neglected airway foreign bodies are often discovered incidentally or when complications of the disease recur. This report describes the case of an elderly patient with a foreign body in the main bronchus, large size, neglected for more than 15 years, who was diagnosed and successfully intervened endoscopically to remove the foreign body at Hue Central Hospital.

Case report: A 75 - year - old male patient was admitted to the hospital because of a persistent cough. History suspected of choking on Sapote nut while eating (>15 years) with transient infiltrative syndrome, later presenting with recurrent lower respiratory tract infections. The patient was examined at a local medical facility but no foreign body was detected. About 1 month before admission, the patient coughed with little blood, so a CT scan of the lung was performed to detect foreign bodies.

Diagnosis: Chronic bronchitis/Forgotten airway foreign body. The patient underwent bronchoscopy with rigid and flexible tubes to remove all foreign bodies.

Conclusion: The diagnosis of an airway foreign body must be performed by an ENT doctor, and taking a history of foreign body exposure with invasive syndrome is crucial to avoid missed cases. Interventional treatment with rigid and flexible bronchoscopy provides optimal efficiency in removing large bronchial foreign bodies.

ABSTRACT

DEVELOPMENT AND EVALUATION OF A SURGICAL WOUND ASSESSMENT TOOL

Objective: Develop and validate a surgical wound assessment tool for the Vietnamese nurses.

Material and methods: The SWAT was developed in three phases. Phase I: developed an initial SWAT based on international evidence-based guidelines and a comprehensive literature review, Vietnamese surgeons then evaluated the initial SWAT. Phase II: wound care nurse experts in Vietnam used an interactive Delphi process to refine and develop a final version of the SWAT. Phase III: the final version of the SWAT was then evaluated among 260 surgical patients to validate its construct validity and inter - ratter reliability.

Results: Phase I: The overall scale-content validity index was 0.98. The SWAT included 30 items. Phase II: six out of 30 items were excluded from the tool. Phase III: results of the Exploratory Factor Ananysis supported a threecomponent structure of the SWAT. The Intraclass Correlation Coefficient value of the overall scale was 0.81 (95% CI 0.68 - 0.89, p < 0.001), confirming excellent inter - rater reliability.

Conclusion: The SWAT is a reliable and valid tool for monitoring and evaluation the status of surgical wound healing and detecting early factors that may increase surgical wound complications.
Dust Grains Cannot Grow to Millimeter Sizes in Protostellar Envelopes
Authors: Silsbee Kedron , Akimkin Vitaly , Ivlev Alexei V. , Testi Leonardo , Gong Munan , Caselli Paola
Published: December 2022

A big question in the field of star and planet formation is the time at which substantial dust grain growth occurs. The observed properties of dust emission across different wavelength ranges have been used as an indication that millimeter-sized grains are already present in the envelopes of young protostars. However, this interpretation is in tension with results from coagulation simulations, which are not able to produce such large grains in these conditions. In this work, we show analytically that the production of millimeter-sized grains in protostellar envelopes is impossible under the standard assumptions about the coagulation process. We discuss several possibilities that may serve to explain the observed dust emission in the absence of in situ grain growth to millimeter sizes.
The Jovian Energetic Ion Environment of Ganymede: Planetary Space Weather Considerations in View of the JUICE Mission

Published: December 2022

Determining the properties of radiation environments inside planetary magnetospheres is one of the key challenges of planetary space weather science. In this work, we expand our recent simulations of the Jovian energetic ion precipitation to Ganymede’s surface to deduce ion circulation patterns at the altitude of ∼500 km. We apply a single-particle Monte Carlo model to obtain 3D distribution maps of the H+, O++, and S+++ populations at the altitude of ∼500 km. We perform these simulations for three distinct configurations between Ganymede’s magnetic field and Jupiter’s plasma sheet, characterized by magnetic and electric field conditions similar to those during the NASA Galileo G2, G8, and G28 flybys (i.e., when the moon was above, inside, and below the center of Jupiter’s plasma sheet). Our results provide a reference frame for future studies of planetary space weather phenomena in the near-Ganymede region. For ions with energies up to some tens of kiloelectronvolts, we find an increased and spatially extended flow in the anti-Jupiter low-latitude and equatorial regions above Ganymede’s leading hemisphere. Our results also show that the ion flux incident at 500 km altitude is not a good approximation of the surface’s precipitating flux. To study, therefore, Ganymede’s surface erosion processes it may be best to consider also low-altitude orbits as part of future space missions. This study is relevant to the ESA JUpiter ICy moons Explorer mission, which will allow a detailed investigation of the Ganymede environment and its implications on the moon’s surface evolution.
Morphological diversity of pistil stigmas and its taxonomic significance of representatives of holoparasitic Orobanchaceae from Central Europe
Authors: Ruraż Karolina , Piwowarczyk Renata
Published: December 2022

The stigma is the terminal part of the carpel which receives pollen during the pollination process. Although the role of the stigmas in pollination is the same for all angiosperms, stigmas structures are very diverse. This study aimed to evaluate intraspecific, interspecific and intergeneric stigmas variability and then find differences of the stigma morphology amongst 24 holoparasitic Orobanche and Phelipanche species and provide new insights into its potential taxonomic value. This paper was also focused on selecting the best diagnostic features that would be used for future stigma analysis in other species of Orobanchaceae. These analyses were conducted with fresh, dry and fixed material using stereomicroscopy from different locations from Central Europe. Twenty-one quantitative or qualitative morphological features were analysed. This study highlights the variation of stigma morphology and characters which are useful to improve the taxonomic understanding of problematic taxa. Thus, two main types of stigmas were established, based on tested features: 1–oval, rarely hemispherical in shape, most often one-coloured with lobes separated in Phelipanche stigmas; 2–spherical to hemispherical, rarely oval, multi-coloured with partially fused or separated lobes in Orobanche stigmas. The best diagnostic features of the stigmas for distinguishing the Orobanchaceae are the type and subtype of stigma, the length and area of the stigma, the width of single lobes, the width in the middle part of the stigma, the length of upper and lower separation in the middle part between lobes and the angle between lobes in the upper and lower part. The morphological features of the stigmas are important criteria for distinguishing genera, sections and subsections, as well as related species. In this study, we present the first stigma morphological studies for the most numerous genera from the tribe Orobancheae and this paper may determine features possible to use in solving certain taxonomic problems and evolutionary relationships of the species.
La satisfaction genrée vis-à-vis de la rémunération : Vers la génération d’une échelle de mesure
Authors: Chelyat Niâma , Sahraoui Doha
Published: December 2022

Bien qu’elles soient conscientes qu’elles gagnent moins que les hommes, les femmes sont plus satisfaites à l’égard de leur rémunération. Plusieurs travaux ont apporté des explications à cette attitude paradoxale. Il existe toute une série de modèles de la satisfaction vis-à-vis de la rémunération ayant adopté une approche quantitative positiviste négligeant simultanément ce que les femmes intègrent lorsqu’il s’agit de porter un jugement sur leur rémunération. Soutenant que cette approche adoptée présente des lacunes dans la mesure où elle ignore la nature « genrée » de la satisfaction à l’égard de la rémunération, le présent travail adopte une position alternative et vise à aborder la satisfaction à l’égard de la rémunération du point de vue des femmes et d’intégrer les rapports de genre intériorisés. En adoptant le paradigme de Churchill, nous visons à développer une échelle de mesure « genrée » relative à la satisfaction vis-à-vis de leur rémunération, comprenant une exploration qui nous permettra d’affiner le concept et bien définir ses facettes.
Évaluation de l’impact de la transparence sur le capital de confiance des banques au Maroc : une étude de contextualisation
Authors: Chraibi Hassan , Dikaoui Omayma
Published: December 2022

La transparence est souvent citée comme un déterminant essentiel de la confiance. Cependant, la signification et l’importance de la transparence n’ont pas encore été vérifiées dans toutes les configurations des relations entre les organisations et leurs parties prenantes. Notre projet de recherche se propose de le faire dans le contexte particulier du secteur bancaire marocain. Dans cet article, nous proposons un modèle de lien entre la confiance et la transparence dans le cadre des relations entre les banques commerciales et leurs parties prenantes, notamment leurs entreprises clientes. Ce modèle étant construit dans un premier temps sur la base d’une analyse de l’état de l’art, nous nous proposons de le renforcer par une étude de contextualisation. Ce travail a permis de réconforter des hypothèses de causalités, tout en suggérant des liens intermédiaires entre clarté et bienveillance et entre clarté et intégrité.
Vaincre la Surprise Stratégique pour l’Économie de la Défense via le Système Stratégique de Signaux Précoces ®
Authors: Welferinger Stephane , Bisson Christophe
Published: December 2022

Si les grandes entreprises possèdent un service de veille stratégique, elles ont de plus en plus de mal à détecter et interpréter les signaux faibles. Cela s’explique par l’accroissement permanent du volume et de l’hétérogénéité des données mais aussi de la complexité de son environnement stratégique. Ainsi, la veille dite «  classique  » souvent silotée, basée sur le modèle ’Intelligence, Modélisation, Choix’ de Simon (1983) apparait être obsolète. Afin de faire face à ces défis, le Système Stratégique de Signaux Précoces ® est proposé comme méthode d’Intelligence Economique et Stratégique et appliqué pour la première fois au secteur de la défense. La modélisation en collaboration avec des experts du secteur et le calcul de scénarii comme les images potentielles futures de ce marché pour l’Europe ont été effectués via le logiciel dédié Stratbrain. Nous avons donc pu calculer les impacts et probabilités des thématiques importantes du secteur et déterminer les vecteurs de résistance ou de développement du domaine. Nous avons pu calculer puis visualiser le scénario le plus impactant à 3 ans (2021) dont la probabilité est assez forte et annonce une croissance molle sur cette région. Ce Système Stratégique de Signaux Précoces ® pourrait guider l’utilisation de l’intelligence artificielle pour constituer un système d’Intelligence Economique et Stratégique augmenté.
On fixed points, their geometry and application to satellite web coupling problem in $ \mathcal{S}- $metric spaces
Authors: Joshi Meena , Tomar Anita , Abdeljawad Thabet
Published: December 2022

We introduce an $ \mathcal{M-} $class function in an $ \mathcal{S-} $metric space which is a viable, productive, and powerful technique for finding the existence of a fixed point and fixed circle. Our conclusions unify, improve, extend, and generalize numerous results to a widespread class of discontinuous maps. Next, we introduce notions of a fixed ellipse (elliptic disc) in an $ \mathcal{S}- $metric space to investigate the geometry of the collection of fixed points and prove fixed ellipse (elliptic disc) theorems. In the sequel, we validate these conclusions with illustrative examples. We explore some conditions which eliminate the possibility of the identity map in the existence of an ellipse (elliptic disc). Some remarks, propositions, and examples to exhibit the feasibility of the results are presented. The paper is concluded with a discussion of activation functions that are discontinuous in nature and, consequently, utilized in a neural network for increasing the storage capacity. Towards the end, we solve the satellite web coupling problem and propose two open problems.
Logistic models to minimize the material handling cost within a cross-dock
Authors: Mukherjee Taniya , Sangal Isha , Sarkar Biswajit , Almaamari Qais Ahmed
Published: December 2022

Retail supply chains are intended to empower effectiveness, speed, and cost-savings, guaranteeing that items get to the end client brilliantly, giving rise to the new logistic strategy of cross-docking. Cross-docking popularity depends heavily on properly executing operational-level policies like assigning doors to trucks or handling resources to doors. This paper proposes a linear programming model based on door-to-storage assignment. The model aims to optimize the material handling cost within a cross-dock when goods are unloaded and transferred from the dock area to the storage area. A fraction of the products unloaded at the incoming gates is assigned to different storage zones depending on their demand frequency and the loading sequence. Numerical example considering a varying number of inbound cars, doors, products, and storage areas is analyzed, and the result proves that the cost can be minimized or savings can be intensified based on the feasibility of the research problem. The result explains that a variation in the number of inbound trucks, product quantity, and per-pallet handling prices influences the net material handling cost. However, it remains unaffected by the alteration in the number of material handling resources. The result also verifies that applying direct transfer of product through cross-docking is economical as fewer products in storage reduce the handling cost.
Modeling and simulation of task rescheduling strategy with resource substitution in cloud manufacturing
Authors: Zhang Xiaodong , Ren Dawei
Published: December 2022

When a cloud manufacturing environment extends to multi-user agent, multi-service agent and multi-regional spaces, the process of manufacturing services faces increased disturbances. When a task exception occurs because of disturbance, it is necessary to quickly reschedule the service task. We propose a multi-agent simulation modeling approach to simulate and evaluate the service process and task rescheduling strategy of cloud manufacturing, with which impact parameters can be achieved through careful study under different system disturbances. First, the simulation evaluation index is designed. In addition to the quality of service index of cloud manufacturing, the adaptive ability of task rescheduling strategy in response to a system disturbance is considered, and the flexibility of cloud manufacturing service index is proposed. Second, considering the substitution of resources, the internal and external transfer strategies of service providers are proposed. Finally, a simulation model of the cloud manufacturing service process of a complex electronic product is constructed by multi-agent simulation, and simulation experiments under multiple dynamic environments are designed to evaluate different task rescheduling strategies. The experimental results indicate that the external transfer strategy of the service provider in this case has higher quality of service and flexibility of service. Sensitivity analysis indicates that the matching rate of substitute resources for internal transfer strategy of service providers and the logistics distance of external transfer strategy of service providers are both sensitive parameters, which have significant impacts on the evaluation indexes.
Galerkin spectral method for a multi-term time-fractional diffusion equation and an application to inverse source problem
Authors: Sun L.L. , Chang M.L.
Published: December 2022

In this paper, we employ the Galerkin spectral method to handle a multi-term time-fractional diffusion equation, and investigate the numerical stability and convergence of the proposed method. In addition, we find an interesting application of the Galerkin spectral method to solving an inverse source problem efficiently from the noisy final data in a general bounded domain, and the uniqueness and the ill-posedness for the inverse problem are proved based on expression of the solution. Furthermore, we compare the calculation results of spectral method and finite difference method without any regularization method, and get a norm estimate of the coefficient matrix of a spectral method discretized. And for that we conclude that the spectral method itself can act as a regularization method for some inverse problem (such as inverse source problem). Finally, several numerical examples are used to illustrate the effectiveness and accuracy of the method.
“speak what terrible language you will”: Fooling with the Other in Shakespeare’s All’s Well That Ends Well
Authors: Hiscock Andrew
Published: December 2022

Drawing upon modern and early modern theorising on the question of language use and the cultural project of social cohesion, this paper focuses upon the construction of Community and the Other through language in one of Shakespeare’s “problem” plays, All’s Well That Ends Well. Concentrating upon the first scene from Act Four of Shakespeare’s bitter comedy, particular attention is given to the many and various implications of verbal violence for comic and other purposes in this theatrical staging of the military encampment. At the heart of this presentation lies the humiliated Paroles (words) with his ambiguous foolery and discordant roles in the intrigue. The article closes reflecting on the implications of the speech act, the witness and the victim when the Other is embodied through language.
“I cannot tell wat is dat”: Linguistic Conflict in Shakespeare’s King Henry V
Authors: Mayer Jean-Christophe
Published: December 2022

Shakespeare’s Henry V is unique in the way that it is a linguistically troubled and conflicted piece of writing. As one of its most recent editors put it, ‘No play of Shakespeare’s makes so much use of differences in language and has more language barriers’. The play is much more than an Anglo-French confrontation seen from an English angle. It anatomises the concept of nationhood: it is slippery, ambivalent, and fluid on the one hand, jingoistic and rigid on the other. Henry V is ideal when it comes to studying scenes in the Other’s language, as well as otherness and alterity. The two scenes this article mainly focuses on – the scene almost entirely in French (3.5), during which Princess Katherine of France tries to learn a few rudiments of English from her servant Alice, and the wooing scene between Henry V and the Princess where Alice acts partly as an interpreter between the two (5.2) – exploit and expose linguistic and cultural faultlines. Both scenes encapsulate many of the issues of the play at large. Moreover, while questioning the idea of foreignness through specific linguistic interplay, they challenge the very notion of Shakespearean scenic division in theatrically productive ways.
Historical Development of Fiscal Policy Operation among Sub-Saharan African Countries
Authors: Jibir Adamu , Abdu Musa , Bappayaya Bashir
Published: December 2022

In recent decades, economists and historians have increasingly turned to Africa’s colonial past to explain contemporary differences in economic outcomes – especially fiscal stance within the African continent, as well as differences between Africa and other regions of the world. This study joins the debate by exploring the historical records of colonial state finances to see their development and possible link with recent fiscal outcomes among Sub-Saharan African countries. The study applies simple descriptive statistical tools for the analysis of data. The study found that taxes constitute the financial and political backbone of the colonial state and were vital to the state building efforts of colonial governments. Similarly, there are significant differences and similarities between British and French territories in terms of tax administration and expenditure policies. In addition, there is greater importance on education expenditure in British colonies, stronger reliance on direct taxation in French colonies. The remarkable achievements in fiscal policy reforms by some SSA countries in recent years has its root to colonial era. To consolidate the gains and to tackle the challenges, it is imperative that SSA policy makers commit themselves – and remain firmly committed – to sound fiscal policies to ensure sustainable growth and development.
Review on Value Chain Analysis of Kothala Himbutu, Salacia chinensis
Authors: Amarathunge Semini Mudara , Prasada D.V.P.
Published: December 2022

Kothala Himbutu has high importance with medicinal value. The goal of this analysis is to get information that wanted to map the value chain, give suggestions, and get associated challenges focused on developing productive and globally competitive industries reliant upon the sustainable management of limited natural resources such as Kothala Himbutu. However, there is a gap in the ethnopharmacological literature in terms of understanding what importance a significant analysis of value chains of the underutilized crop, Kothala Himbutu could have. For this study, a mixed-methods approach focuses on a general review of the literature in a systematic online search with a hand search of bibliographies and discussions with respondents such as Ayurvedic practitioners, medicinal plant cultivators, herbal plant collectors, middlemen, Ayurvedic drug sellers, Ayurvedic drug manufacturers, and herbal raw material suppliers. The overall value chain operates with little vertical integration and almost no horizontal collaboration. Downstream activities depended on market demand while upstream activities were on value addition. Consumer awareness of value-added Kothala Himbutu products was insufficient due to the unavailability in the market. Our paper takes a critical stocktake of Kothala Himbutu value chain in Sri Lanka and focused to identify its role in rural medicine and income security.
Language Alienation of Sri Lankan Students Studying Overseas: An Empirical Study
Authors: Pabodha GPH , Abeywickrama Rohan
Published: December 2022

Every year, a considerable number of Sri Lankan students migrate overseas to further their studies. In comparison to previous years, the total number of students emigrating has increased significantly. Especially, in such countries, many migrant students are able to find new opportunities for their career development other than furthering their education. This qualitative research aims to examine the language alienation of Sri Lankan students studying overseas and how it has hindered the achievement of their academic outcomes. Ten migrant students studying in Canada and Australia for more than six months were selected as participants in the study. Semi-structured interview was administered to gather data and Thematic Analysis (TA) was used to arrange, analyze and interpret the data. The findings of the study revealed that 90% of the participants experienced language alienation upon arrival in these countries. They could not complete many of their daily tasks, such as making friends, understanding lectures, and participating in classroom events, due to the language barrier. Participants reported that the inadequate opportunity for enhancing their English communication skills in ESL classrooms in Sri Lanka is the key reason for this situation. As they claim, Sri Lankan primary and secondary education should give equal significance to all the English skills in the English curriculum rather than prioritizing writing and reading in examinations. This claim points to the need of practising speaking and listening in ESL classrooms without focusing only on examination-oriented teaching.
Geometrically Exact Beam-based Aeroelastic Modeling and Solution Of Composite Rotor Blades in Forward Flight
Authors: Shang Lina , Xia Pinqi , Hodges Dewey H. , Lin Changliang
Published: December 2022

In this paper, the geometrically exact beam model and aeroelastic solution methods for composite rotor blades in forward flight by the latest variational asymptotic beam sectional analysis (VABS) have been employed. The geometrically exact beam equations of motion in the mixed variational
form and the latest VABS are used to deal with one-dimensional blade analysis and the structural property of blade cross section, respectively. The methods can be used for the aeroelastic solution of composite rotor blades with arbitrary cross-sectional shape and material distribution, large
deflections and significant nonclassical effects such as cross-sectional warping, transverse shear deformation, and elastic couplings caused by anisotropic material properties. The Peters–He finite state dynamic inflow model and the Peters finite state airloads theory are used to calculate
the induced velocity and blade airloads, respectively. An auto-pilot trim scheme is used for calculating the blade pitch controls to meet the trim requirements. The convergence issue encountered when solving the geometrically exact, mixed variational aeroelastic equations in time domain has
been successfully addressed. The values of the empirical parameters in the auto-pilot trim scheme for the presented aeroelastic model have been properly selected. The accuracy of the presented aeroelastic modeling and solution methods has been verified against the SA349/2 flight-test data.
The influence of transverse shear deformation on the aeroelastic response of composite rotor blades was also investigated, indicating that this effect has a nonnegligible influence on the aeroelastic response of the five different kinds of elastically coupled hingeless composite rotors investigated
in this paper.

The objective of this study is to search for features and indicators from the identified geothermal resource sweet spot in the south Mount Meager area that are applicable to other volcanic complexes in the Garibaldi Volcanic Belt. A Landsat 8 multi-spectral band
dataset, for a total of 57 images ranging from visible through infrared to thermal infrared frequency channels and covering different years and seasons, were selected. Specific features that are indicative of high geothermal heat flux, fractured permeable zones, and groundwater circulation, the
three key elements in exploring for geothermal resource, were extracted. The thermal infrared images from different seasons show occurrence of high temperature anomalies and their association with volcanic and intrusive bodies, and reveal the variation in location and intensity of the anomalies with
time over four seasons, allowing inference of specific heat transform mechanisms. Automatically extracted linear features using AI/ML algorithms developed for computer vision from various frequency bands show various linear segment groups that are likely surface expression associated with local
volcanic activities, regional deformation and slope failure. In conjunction with regional structural models and field observations, the anomalies and features from remotely sensed images were interpreted to provide new insights for improving our understanding of the Mount Meager geothermal system
and its characteristics. After validation, the methods developed and indicators identified in this study can be applied to other volcanic complexes in the Garibaldi, or other volcanic belts for geothermal resource reconnaissance.

Frailty is a clinically measurable state of vulnerability to developing increased dependency and/or mortality when exposed to a stressor. Chronic diseases, aggressive treatments, antibiotic overuse, microbiota changes, immune senescence, and increased use of medical devices and implants (i.e., central lines and catheters) expose modern patients to healthcare-associated infections (HAIs), multidrug-resistant bacteria, and new and unusual opportunistic pathogens. Older adults are among the main victims of HAIs and are associated with high costs, disability, morbidity, and mortality. Ralstonia pickettii is an emerging opportunistic pathogen that causes rare nosocomial infections in frail individuals. Herein, we present a case of bloodstream infection caused by R. pickettii in an 88-year-old woman with a relatively mild course. In addition to describing this unusual finding, this report discusses the problem of HAIs in older adults. Older age, comorbidities, and hospital admissions were among the main risk factors for HAIs. Adherence to guidelines, training, auditing, and surveillance is crucial for reducing the burden of HAIs in acute settings. Furthermore, avoiding incongruous hospitalizations would have positive implications both for preventing HAIs and improving patient quality of life.

Nickel based super alloys are being studied for possible use in ultra-super critical thermal power plants. This paper reports tensile strength and hardness variation of these alloys at room temperature and 700C. The objective of this research is to compare cast, extruded INCONEL 625 alloys and propound theories explaining mechanical behaviour. Both cast and extruded samples were studied and the results have been reported. Extruded samples showed higher strength and lower ductility. Both yield strength curve and tensile strength curve showed serrations and the concept of serrations has been elaborated with available theories on serrations. Microstructures were analysed using optical microscope and scanning electron microscope.

Battery-Electric Buses (BEBs) are expensive compared to diesel buses and the biggest problem in the battery operated electric vehicle is always the range. The electric consumption is very high during extreme cold and extreme hot climates. Around the world, the developing economies are deploying BEBs on a large scale with the idea of sustainable green mobility. In this context it is required to reduce the energy consumption required for BEBs during extreme cold and hot weather. For this purpose, it is required to implement energy conservation procedures to prevent the heat entry and heat loss in the HVAC system of the BEBs. For simulating the transient effect of external solar load on the air-conditioning system of the vehicle, commercial Computational Fluid Dynamics software is used. In this project, simulation of energy consumption in a BEB is carried out using ANSYS FLUENT software. An energy conservation parametric study with different types of glass and wall materials has been carried out. There is a reduction in energy consumption of 20.52 % when using hard-coated solar glass and 26.07 % reduction when polyethylene insulation is used.

In recent years, one of the key emphases in electric car research has been batteries. Long-established battery technologies, such as lead-acid batteries, are necessary, but they must be upgraded. Lithium-ion batteries, for example, are a new technology that has lately entered the market. The introduction of hybrids, plug-in hybrids and electric vehicles has broadened the range of automobiles available. The energy density, charging and discharging properties, system integration and cost of battery technologies can all be used to classify them. Calendar life, cycle life, performance and safety at low and high temperatures are all important performance characteristics. In this study, a detailed comprehensive review has been done related to the development in battery technology for future mobility.

Published: December 2022

This paper presents the application of Eshelby-Mori-Tanaka-based micromechanical models for the properties prediction of misoriented carbon fiber composites. Fiber orientation and length distribution are used in property prediction. Empirical models, which capture the distribution of fiber orientation and fiber length in each direction are used in this study. Carbon epoxy composites, made from needle-punched carbon felt, are used in the paper. Fiber orientation and length distributions are determined for this composite. The empirical model was calibrated with the data obtained from needle-punched carbon epoxy composites. The effect of orientation and aspect ratio on the elastic modulus of composites is studied in this study. The prediction has been validated through the experimental results.

Published: December 2022

Al6061 alloy with 80-to-90-micron sized B4C reinforced metal composites were synthesized using two steps stir cast process. The developed composites were characterized for microstructural characterization with SEM/EDS and XRD. Al6061 alloy with 9% wt. of B4C reinforced composites were shown uniform particles distribution in Al matrix. Furthermore, EDS and XRD patterns confirmed the availability of these reinforced particles in the metal composites. Hardness, tensile, compression, impact and fatigue tests were done to discover the effect of adding B4C to the base alloy on the mechanical properties of the composites. The first four strengths as above were discovered to be more with the addition of B4C particles. There was a slight decline in the fatigue life and elongation of Al6061-B4C composites when compared with the base alloy.

Published: December 2022

This study aims to design a self-levelling platform loaded with a missile that is articulated from 0° to 90°. The platform is not situated rigidly on the ground, but it is placed on a railway track. This creates an unbalanced condition for the platform during the missile articulation because the railway guides are not rigid and act as springs. Consequently, the objective of study was to keep the platform in a steady condition at a particular plane at all times, irrespective of the change in load with respect to position and time. A prototype was designed on CATIA V5 software and tested by using Arduino IDE which replicates the original system on a small scale. The effect of railway track was created by using springs of various stiffness coefficients. The model was manufactured and the balancing of the platform was done using linear actuators coupled with an electronic control system with a feedback mechanism. The accelerometer was used to sense the angular variation in X and Y axes along the reference plane. The electro-mechanical linear actuators were used to nullify the unbalance and hence the levelling was achieved. The various tests were performed on the prototype with variable ground conditions using different combinations of springs to validate the balancing principle. It reveals that the levelling was successful with all combinations for any unbalanced ground condition.
