Reconstruction des premières enveloppes dans la psychothérapie d’une enfant autiste
Authors: Provoost Adeline
Published: December 2023

Cet article s’intéresse au processus de reconstruction des enveloppes corporo-psychiques chez une enfant autiste de trois ans, suivie en psychothérapie. Après un temps d’accueil mère-enfant, basé sur le principe de la co-construction narrative, la thérapie individuelle s’est orientée vers des expériences très précoces de recherche d’une contenance première, ouvrant la voie à un accès plus grand au langage et à l’intersubjectivité.
La notion de traumatisme
Authors: Lindenmeyer Cristina
Published: December 2023

De nos jours, la notion de traumatisme est loin d’être méconnue. Au contraire, l’usage populaire en a pris possession en l’appliquant de mille et une manières, lui donnant, parfois, un sens éloigné de ce qu’elle traduisait à son origine. En outre, l’emploi de cette notion ne se limite pas à la problématique du sujet individuel mais peut aussi faire référence aux adversités vécues par des groupes de personnes. Si cette notion a pu être soumise à de nombreuses extrapolations théoriques ou purement linguistiques, elle reste néanmoins pertinente dans la mesure où elle nous aide à mettre du sens face aux récits des certains patients que nous rencontrons dans pratique actuelle. Dans ce texte, l’auteur retrace la conception de la notion de traumatisme par Freud.

Published: December 2023

La réponse à la question de la place des familles dans la prise en charge d’enfants avec autisme semble actuellement établie, à savoir que les parents sont des partenaires indispensables du soin, tant sur la question évidente du projet de soin et d’orientation, que sur la connaissance de leur enfant et la façon dont il est nécessaire de l’appréhender. Néanmoins, dans les faits, il est parfois difficile de créer une manière adéquate, confortable pour les soignants et les parents d’intégrer ces derniers aux soins de leur enfant. Nous présentons dans cet article la façon dont les équipes de notre hôpital de jour travaillent au quotidien avec les familles ; nous partageons une partie de notre cheminement et exposons différentes modalités d’accueil des familles.
« Éclipse de raison »François Lamy contre la musique
Authors: Benigni Fiormichele
Published: December 2023

Dans son volumineux traité De la connoissance de soi-mesme , le bénédictin cartésien François Lamy fait plusieurs références à l’expérience musicale et aux relations entre la musique, la poésie et la rhétorique. L’enquête du philosophe se situe à la fois au niveau de l’analyse moraliste et à celui de la description des processus neurophysiologiques. Cependant, derrière la condamnation des effets de la musique et des dangereuses dynamiques passionnelles qu’elle déclenche, l’ouvrage de Lamy esquisse une réflexion générale sur les « idées accessoires » et les pensées « sourdes » et « clandestines » qui échappent à la conscience du sujet.

Chaos emergence and dissipation in a three-species food web model with intraguild predation and cooperative hunting
Authors: Sk Nazmul , Mondal Bapin , Sarkar Abhijit , Santra Shyam Sundar , Baleanu Dumitru , Altanji Mohamed
Published: December 2023

We explore the dynamics of a three-species Lotka-Volterra model incorporating intraguild (IG) predation. The model encompasses interactions between a basal prey, intraguild prey and omnivorous top/intraguild predator. These interactions are characterized by linear functional responses, while considering intraspecific competition and cooperative hunting dynamics. The study involves a comprehensive stability of different steady states and bifurcation analysis. Bifurcation structures unveil shifts in equilibrium stability and the emergence of new equilibrium states. Investigation into dynamics around the coexistence equilibrium highlights diverse behaviors, including stable coexistence, oscillations and chaos. Furthermore, exploration of species' densities under parameter variations uncovers distinct patterns, ranging from stability to chaos. Incorporating the concept of hunting cooperation among IG predators and IG prey can lead to the emergence or suppression of chaotic oscillations, respectively. Additionally, we observe that lower consumption rate of IG predator and cooperation of IG predator helps the system to keep in a stable state position.
An improved memetic algorithm to solve the energy-efficient distributed flexible job shop scheduling problem with transportation and start-stop constraints
Authors: Gu Yifan , Xu Hua , Yang Jinfeng , Li Rui
Published: December 2023

In the current global cooperative production environment, modern industries are confronted with intricate production plans, demanding the adoption of contemporary production scheduling strategies. Within this context, distributed manufacturing has emerged as a prominent trend. Manufacturing enterprises, especially those engaged in activities like automotive mold production and welding, are facing a significant challenge in managing a significant amount of small-scale tasks characterized by short processing times. In this situation, it becomes imperative to consider the transportation time of jobs between machines. This paper simultaneously considers the transportation time of jobs between machines and the start-stop operation of the machines, which is the first time to our knowledge. An improved memetic algorithm (IMA) is proposed to solve the multi-objective distributed flexible job shop scheduling problem (MODFJSP) with the goal of minimizing maximum completion time and energy consumption. Then, a new multi-start simulated annealing algorithm is proposed and integrated into the IMA to improve the exploration ability and diversity of the algorithm. Furthermore, a new multiple-initialization rule is designed to enhance the quality of the initial population. Additionally, four improved variable neighborhood search strategies and two energy-saving strategies are designed to enhance the search ability and reduce energy consumption. To verify the effectiveness of the IMA, we conducted extensive testing and comprehensive evaluation on 20 instances. The results indicate that, when faced with the MODFJSP, the IMA can achieve better solutions in almost all instances, which is of great significance for the improvement of production scheduling in intelligent manufacturing.

Published: December 2023

Accurate cloud detection is an important step to improve the utilization rate of remote sensing (RS). However, existing cloud detection algorithms have difficulty in identifying edge clouds and broken clouds. Therefore, based on the channel data of the Himawari-8 satellite, this work proposes a method that combines the feature enhancement module with the Gaussian mixture model (GMM). First, statistical analysis using the probability density functions (PDFs) of spectral data from clouds and underlying surface pixels was conducted, selecting cluster features suitable for daytime and nighttime. Then, in this work, the Laplacian operator is introduced to enhance the spectral features of cloud edges and broken clouds. Additionally, enhanced spectral features are input into the debugged GMM model for cloud detection. Validation against visual interpretation shows promising consistency, with the proposed algorithm outperforming other methods such as RF, KNN and GMM in accuracy metrics, demonstrating its potential for high-precision cloud detection in RS images.

Computer-Aided Instruction (CAI) is one of the interactive teaching methods that electronically presents instructional resources and enhances learner performance. In health settings, using CAI is one of the important ways to improve learners’ knowledge and usefulness in their healthcare specialization yet there is still a lack of research that offers a comprehensive synthesis of investigating into the adoption of CAI in healthcare. This research aims to provide a comprehensive review of related literatures on the enablers and barriers for technology adoption of CAI in healthcare. 31 journals were analyzed and revealed that several studies were utilizing the Unified Theory of Acceptance and Use of Technology (UTAUT). The researchers then conducted qualitative coding for thematic analysis and categorized the qualitative data to find themes and patterns. Enablers as well as barriers to CAI adoption in healthcare were then discussed along with the common conclusions, limitations and recommendations for future studies. Results shows that key enablers were perceived ease of use, ease of usefulness, performance expectancy, social influence, user experience, and effort expectancy while identified key barriers were government support, funding constraints, and interactivity. The majority of the research articles highlighted the benefits of CAI in healthcare education as an innovative method for boosting the effectiveness of both teaching and learning.
Verdade e Justiça em Emmanuel Levinas
Authors: Carrara Ozanan Vicente
Published: December 2023

Para se abordar a questão da verdade, no pensamento de Levinas, faz-se necessário procurar antes o seu fundamento que, na ética como filosofia primeira, é a justiça. Em seguida, é preciso fazer o caminho da fenomenologia levinasiana em diálogo com as fenomenologias de Husserl e Heidegger, além de passar pelo modo como Kierkegaard compreende ética. Levinas busca o Sentido dos sentidos, distanciando-se de Husserl para quem o sujeito é a fonte de todo sentido; mas também se distanciando da ontologia de Heidegger que opera uma redução de tudo ao ser, suprimindo a exceção do Outro. Se Kierkegaard descobriu a interioridade como marca indelével da subjetividade que recusa se perder na obra da totalização, ele não consegue escapar de outra violência que não compreende a exterioridade como vindo de fora de todo Sistema, deixando o ético se perder no geral. A relação ética, tal como Levinas a compreende, é, ao contrário, uma relação de único a único. A significação primeira da Verdade é de ordem ética e não se entende senão em relação com a justiça - retidão do face a face - que a ontologia traduzirá tardiamente como verdade que se mostrará no ser.

The key integral factors of cold chain industries have been identified on the basis of an extensive literature review as well as analyzing the influencing factors through the KMO Test for identification of the factors of cold chain performance. The end result will establish a relationship between high driving powers with low dependences and high strategic dependencies with low significance. It will also identify the major inhibitors, their role in the operation, and their effect on a cold chain in India.
Oxidation Behavior of Atmospheric Plasma Sprayed NiAl Coating at High Pressure Oxygen Atmosphere
Authors: Zhang Li , Liao Xian Jin , Luo Xiao Tao , Li Chang Jiu
Published: December 2023

The high-temperature and high-pressure oxygen-rich combustion gases often cause the high temperature gas conduit in rocket engine to suffer severe oxidation, resulting in a reduced service life. The present study deposited a dense NiAl coating on GH4202 superalloy using atmospheric plasma spraying and investigated its oxidation behavior in a high temperature and high-pressure oxygen atmosphere. The results showed that the NiAl coating presented excellent bonding with the superalloy substrate throughout tests. The uncoated GH4202 substrate was severely oxidized during high pressure oxygen atmosphere. It was found that only a continuous very thin Al2O3 oxide scale evolved on the NiAl coating surface and no oxidation was observed at the interface between the NiAl coating and GH4202 substrate. Moreover, no significant inner oxidation occurred to NiAl coating. Therefore, the present APS NiAl coating can provide effective protection of superalloy from oxidation at high pressure oxygen combustion gas atmosphere.
Development of Functionally Graded Metal-Ceramic Systems by Directed Energy Deposition: A Review
Authors: Ratnala Dilipkumar Choudary , Andersson Joel , Joshi Shrikant
Published: December 2023

Ceramics and metals are the two vastly explored classes of materials whose individual characteristics and targeted applications differ significantly. Continuous thrust for space exploration and energy generation demands materials with a wide range of properties. To tackle this demand, ceramic-metal combined structures that club heat, wear, and corrosion resistance of ceramics to the high toughness, good strength, and better machinability of metals are desirable. While various processing routes to combine ceramics and metals have been developed through the years, solutions to address problems associated with the interface, thermal property mismatch, and poor adhesion need to be explored. In this context, Functional Graded Materials (FGMs) have attracted particular attention by virtue of their ability to avoid sharp interfaces and local stress concentrations. Out of all, Additive Manufacturing (AM) routes, particularly the Directed Energy Deposition (DED) technique, is emerging as a productive technique capable of fabricating a wide range of metal-ceramic graded structures. This paper specifically discusses metal-ceramic FGMs ́ capability as a potential high-temperature material with customized multifunctional material properties. It further outlines the primary concerns with the realization of metal-ceramic graded structures and major techniques developed to mitigate problems encountered in processing them. Specific emphasis is laid on the powder-based Laser DED (L-DED) technique of FGM fabrication owing to its control over complex geometries and microstructural engineering.
Numerical Modeling of In-Flight Molten Metal Droplet Dynamics and Particle Oxidation in Atmospheric Plasma Spraying
Authors: Mahrukh Mahrukh , Zhang Li , Liu Sen Hui , Li Chang Jiu
Published: December 2023

In Atmospheric Plasma Spraying (APS), it is important to understand the controlling factors dominating molten metal droplets’ reaction dynamics to control final coating compositions and properties. The present paper focuses on a novel Computational Fluid Dynamics (CFD) modeling of mass transfer mechanisms of an inflight molten metal droplet leading to droplet oxidation control during APS. The onset conditions of droplet internal circulation and its effect on the deoxidizer oxidation behavior during APS are theoretically examined. Moreover, rapidly supplying these elements from the inside to the droplet surface requires the rapid switching of the mass transfer mechanism to rapid convective flow due to a very limited in-flight time of less than 1ms. The temperature and velocity variations within the droplet would influence the thermo-physical properties of the droplet and the plasma gas and it controls the onset of the internal circulations within the droplets. A novel User Defined Function (UDF) is developed to capture the onset of Hill’s vortex formation and its effect on the rapid-rate convective mass transfer mechanism during APS. Further, a detailed analysis of particle size effect on in-flight in-situ deoxidation during APS of NiAlC droplets was performed. It is observed that the smaller size droplets will undergo more severe oxidation during a flight than larger size droplets due to more molecules of O2 available for reaction in the smaller droplet.

Authors: Schreyer Manuela , Gerber Alexander , Neubert Steffen
Published: December 2023

Optimizing the manufacturing process to increase the product quality is a major challenge most industry branches just like aluminum production have to face. To continuously improve the production quality, it is necessary to develop new methods to identify parameters which may influence the product quality. Influencing parameters can be found at various production steps. Production data is recorded by numerous sensors throughout the entire manufacturing process. The goal is to develop methods for analysing the sensor data from each step of the production process to effectively identify specific patterns that may indicate critical process parameters along the production chain. The work shows feature extraction methods to find characteristics in the sensor data that could affect the product-quality.
Effect of Special Plating Films on Galvanic Corrosion Behavior between Metal and CFRTP
Authors: Kobayashi Tatsuya , Shimizu Kei , Shohji Ikuo
Published: December 2023

In this study, electrochemical measurements and observations investigated galvanic corrosion behavior between various metals with or without projection-shaped Ni–Cu alloy plating film and carbon-fiber-reinforced thermoplastic (CFRTP) of corroded areas. Stainless steel, aluminum alloy, and CFRTP plates were prepared. Ni and Ni–Cu alloy electroplating were performed on the stainless steel plate. Electroless zinc plating, Ni, and Ni–Cu alloy electroplating were performed on the aluminum alloy plate. The galvanic current between the metal and CFRTP plates was measured using an electrochemical measurement system. The test solution was 0.06 mol/L NaCl aqueous solution. For Stainless steel/CFRTP, the galvanic current flow was negligible with and without the Ni–Cu alloy plating film. For aluminum alloy/CFRTP without the Ni–Cu alloy plating film, the galvanic current ranged from-80 to-120 μA/cm2 at a test temperature of 60°C. For aluminum alloy with the Ni–Cu alloy plating film, the galvanic current ranged from-60 to-80 μA/cm2. The galvanic current for the aluminum alloy plate with Ni–Cu alloy plating was lower than that of the aluminum alloy plate without Ni–Cu alloy plating film. The result suggests that the formation of the Ni–Cu alloy plating on the aluminum alloy improves corrosion resistance.
Interactive Evaluation of Interfacial Damages on Loosening Behavior of Acetabular Cup Loosening Using AE and IR Method
Authors: Otsuka Yuichi , Sakonju Takuya , Miyashita Yukio
Published: December 2023

We aim at revealing the damage behavior of HAp sprayed coating on the surface of acetabular cup subjected to cyclic loading using AE (Acoustic Emission) method and IR (Infrared thermography) methods. Fatigue test was conducted in SBF(simulated body fluid), and the displacement of acetabular cup embedded in simulated bone was measured by two cantilever pairs. Acoustic emissions from delamination or wear of HAp coating were also measured by AE method, and the temperature change due to friction and wear near the top was measured by IR method. The analysed result could estimate the process in which delamination occurs in the initial stage of test and then friction and wear occur. The rotation displacement of acetabular cup could be associated with cracking or delamination of the HAp sprayed coating, friction and wear at the interfaces between simulated bone and acetabular cup. The subsidence displacement of acetabular cup can be caused by collapse of the simulated bone accompanied by an increase in AE energy as well as an increase in dissipated energy. Combined analyses using AE method and IR method clarified that the inelastic damages in simulated bone at the top of acetabular cups could lead the acceleration of both normal and rotational displacement of the acetabular cup whereas interface damages also attributed to exaggerate the displacement by deteriorated fixation.
Challenge to Performance Evaluation of Fusion Reactor Materials by Fission Neutron and Charged Particle Irradiation
Authors: Muroga Takeo
Published: December 2023

Since there are no fusion reactors generating high-flux 14 MeV neutrons, it is necessary to evaluate materials’ performance in fusion reactors based on a correlation of fission neutron and charged particle irradiations. However, the irradiation tests involve various issues which prevent simple correlation and evaluation. In this paper, the issues related to irradiation temperature control and dose rate effects are pointed out and analyzed, and proposals regarding future irradiation tests are given.

Published: December 2023

Typically, samples for PCR instruments are prepared manually by trained laboratory personnel, which in this case refers to the sample preparation, the dispensing of a master mix and a biological sample with subsequent mixing. To reduce the workload, there are approaches towards fully automated PCR systems, but in most cases only proprietary thermal cyclers can be used. Other approaches involve a similarly complex robotic solution. In this work, the spectrum was extended by a method that can be integrated into the workflow of existing PCR protocols. For this purpose, a user-friendly solution using a microfluidic chip was developed. For the sample preparation different mixing concepts were selected as well as a concept for aliquoting. Optimization and evaluation were assisted by utilization of simulations to study system behavior. The systems consisting of a mixer and a flow splitter were manufactured by milling. Subsequently, the mixing and aliquoting capability of the system could be investigated in the laboratory assembly. The testing of this prototype showed moderate results which are attributed to the accuracy of the laboratory assembly.

Published: December 2023

Considering its very good mechanical properties, especially the high strength and toughness, and also its well-known case-hardening ability, the AMS 6265 (9310 VAR) low alloy steel is widely used in the aeronautical industry for manufacturing heavy-duty products and parts, like pinions, shafts, gears, piston pins, and other critical aircraft components. In this study, a surface modification treatment via shot peening method was applied to an initially case-hardened (quenched and carburized) AMS 6265 aircraft steel. In shot peening, the mechanical properties of the surface layer are improved, by generating plastically deformed micro-areas when exposing the metal surface to a stream of steel, glass, or ceramic shots. The initial case-hardened AMS 6265 alloy steel and all surface treated samples were structurally investigated by means of OM (optical microscopy), SEM-BSE (scanning electron microscopy – backscattered electrons imaging), and XRD (X-Ray diffraction) analysis, being also mechanically tested in tensile and microhardness tests. The influence of different shot peening parameters (shot size, peening pressure, and exposure time) on mechanical properties evolution and microstructural features, for the analyzed AMS 6265 alloy steel, was established in this present research.

Recently, ultracompact electric vehicles (EVs) have begun to be sold, instead of general vehicles equipped with gasoline engines, for transportation. However, because the outer plate of an ultracompact EV has low rigidity, the road noise generated by rotation and the wind noise generated from the vehicle's projection shape are transmitted to the inside of the EV. This interior noise reduces the ride comfort for passengers. Therefore, an active noise control (ANC) system was proposed for controlling noise transmitted from the outside of the EV. The proposed ANC system was configured to control the sound generated using a giant magnetostrictive actuator on the wall surface in the cabin of the EV, instead of a vehicle installation speaker.In this study, Tb, Dy, and Fe powders, which are giant magnetostrictive materials, were mixed and mechanically alloyed to produce multiple giant magnetostrictive materials to be used in the proposed ANC system. The displacement of each alloyed giant magnetostrictive material was measured. In addition, each alloyed material was analyzed using X-ray diffraction and their crystal orientation was confirmed.

Published: December 2023

Organ models that resemble the original anatomy are needed in the education and training of human and veterinary doctors. The organs should be as close as possible to the original in shape, colour and feel. Furthermore, these organ models must be able to be handled in such a way that they can be examined by palpation and imaging (ultrasound, X-ray, CT and endoscopy). The diagnostic procedures should detect pathologies such as cysts, tumours, ruptures, haemorrhages or air collections. Following the diagnostic measures, it must be possible to initiate a therapy. Possible therapeutic measures are surgery with a scalpel, electrosurgery or puncture. The present work deals with the production of training models by means of a casting process. With this method, the models can be produced quickly and at low cost. Different compositions of hydrogels and other biomaterials are investigated. These gels are examined for the following properties, among others: thermostability, electrical conductivity and dimensional stability under pressure. Other parameters such as pot life, cross-linking time and durability in relation to mould formation will also be considered.

Introduction: Unlike in developed countries, there is no established expanded newborn screening (eNBS) in resource-limited settings. In Sri Lanka, the Ministry of Health has adopted screening only for congenital hypothyroidism, critical congenital heart diseases and congenital deafness as a policy in all newborns. Hence, there is a requirement to assess the need for eNBS in Sri Lanka. This requires epidemiological studies of the inherited metabolic disorders (IMDs) before investment to ensure costeffectiveness of the programme and reflections on acceptance by beneficiaries.Objectives: To evaluate the pregnant women's knowledge, attitudes and willingness towards eNBS.Method: A descriptive cross-sectional study was conducted at the Mahamodara Maternity Hospital antenatal clinics, Galle, Southern Province, Sri Lanka. A convenient sample was obtained from the antenatal clinics. A pre-tested intervieweradministered questionnaire was used to assess basic socio-demographic details, knowledge and perception of eNBSResults: A total of 602 pregnant women took part in the study. The mean age was 29±5.7 years; 67% were in the 25-40-year age group; 37.2% were primigravida and 60% were in the third trimester. More than 50% of the study participants knew about the heel prick test done at birth. However, only 34.8% and 28% were aware of the screening for congenital hypothyroidism and congenital heart disease, respectively; 93.6% of mothers had not heard of the term IMD, and only seven were aware of the term eNBS. Nevertheless, more than 80% of participants were willing to screen their babies at birth for underlying IMDs, even if it is available on payment, as the current programme was free of charge to the family. Similarly, 96.2% were willing to screen their babies for incurable diseases.Conclusions: Though most women were aware of the heel prick test done at birth, only a suboptimal proportion of them was aware of the disease/s checked using the test. In addition, there was poor knowledge about the IMDs and eNBS. However, there were positive attitudes towards eNBS.

Design and Failure Analysis of Motorbike Sub-frame Using Finite
Element Analysis
Authors: Sharma Ashish , Khare Saharash
Published: December 2023

All two-wheeler industries validate their product’s fatigue life on proving track
before heading for mass production. Proving test tracks are made to simulate the
end-user environment in order to find out the possible fatigue failures during
each development stage of vehicle design, which in turn helps the CAE analysts
to verify the design before it goes to the end-user hands. In this article we
present the design and failure analysis of sub-frame assembly of motorbike
observed during the accelerated fatigue test on proving track. Sub-frame main
rod was found broken exactly between two weld endings during fatigue test before
reaching 6% of the target fatigue life. Possible causes of sub-frame failures
have been identified/analyzed in detail using fish bone diagram. A finite
element analysis (FEA) model of sub-frame assembly was developed and a random
response analysis was carried out on initial design. Acceleration input loads
measured from test track have been given at the sub-frame mounting points to
calculate output responses. Output responses show a high magnitude of amplitude
stresses on the sub-frame main rod exactly where track test failure occurred.
Fishbone diagram analysis indicates that the improper design of the stay
bracket, stress concentrations regions in the design, improper weld/tool
fixture, and method of welding could be reasons for failure. FEA on the final
design concept shows a reduction of amplitude stress to 49% and an increase of
fatigue life to an infinite limit as compared to initial design.
Bioactivity-guided fractionation of antimalarial active extract of Spondias mombin Linn stem bark
Authors: Orumwensodia Kissinger O. , Uadia Patrick O.
Published: December 2023

Herbs have proven to be viable therapeutic alternatives for treatment of diseases like malaria. This study explores the phytochemical, nutritional, antioxidant and antimalarial potentials of Spondias mombin Linn. stem bark. Hexane, methanol, ethanol and aqueous extracts were separately obtained from dried pulverized stem bark, while the most active extracts were fractionated by column chromatography. Extracts/fractions were screened for phytochemical, nutritional and antioxidant properties using established protocols, while antimalarial activity was against Plasmodium berghei NK65 in mice using the chemo-suppressive, prophylactic, curative and mean survival time (MST) tests. Phenolics, flavonoids and tannins were detected in all the extracts. Percentage nutritional composition of the plant material showed it contained moisture (5.14 ± 0.01%), crude fibre (1.00 ± 0.01%), nitrogen free extract (66.18 ± 0.42%), crude protein (7.42 ± 0.10%), crude fat (18.24 ± 1.01%) and crude ash (2.03 ± 0.01%). The extracts scavenged ferrous and DPPH radicals with methanol extract having the highest antioxidant activity. Extracts reduced parasitaemia and prolonged MST relative to infected untreated group. Aqueous and ethanol extracts were the most active in the chemosuppressive (81.63%: MST 20.00 ± 2.21 days) and prophylactic (87.48%: MST 18.20 ± 2.48 days) tests respectively. The hydro-ethanol extract was partitioned into hexane, hexane:ethylacetate-HE, ethylacetate-EA, ethylacetate:methanol-EM and methanol residue-MR fractions. The fractions had varying antimalarial activity with some almost doubling MST relative to infected untreated group.

Published: December 2023

More than a health crisis, the Covid-19 pandemic turned out to be a major disruptive factor influencing the psychological well-being of the survivors. The Covid lockdown, thus provided the recent global brush with boredom, with boredom assuming different faces and persona. The stay-at-home orders had not accounted for this complimentary disease of a phenomenon initially. The confinement for uncertain periods of time proved to be mentally extolling as much as it was anything else. This essay tries to look into the psychological and physiological manifestations of Covid induced boredom as reflected in the select poems of Steeve Wheeler’s Ellipsis and Jane Marla Robbins’ Poems of Covid-19: Stuck in Lockdown: The First Three Months.

Background

Anti-inflammatory diets have shown effective in reducing pro-inflammatory cytokines, and neuropathic pain and depression in individuals with spinal cord injury or disease (SCI/D). However, work to date has focused on community-dwelling individuals with SCI/D, and the diet’s efficacy in an inpatient population, and the feasibility of offering it in a hospital, are unknown. The inpatient setting may be ideal for introducing an anti-inflammatory diet, as immune-related health complications peak acutely after SCI, and forming new dietary habits may be easier in an inpatient setting. Thus, it is necessary to investigate the feasibility of an anti-inflammatory diet in the inpatient SCI/D setting.

Objectives

Phase 1: Understand the nutritional value of the current meal plans in selected inpatient SCI/D hospitals and their compliance with our anti-inflammatory diet.

Phase 2: Understand the opinions that inpatients with SCI/D have regarding their currently offered meal choices and their readiness to learn about, and adopt, an anti-inflammatory diet.

Phase 3: Understand the barriers and facilitators for implementing an anti-inflammatory diet in an inpatient setting from the perspective of hospital administrators.

Proposed Design/Methods

This study will take place in the SCI inpatient settings in two Ontario hospitals. Four to five inpatients from each site will be interviewed in Phase 1 and 2, and four to five Food Services administrators from each site will be interviewed in Phase 3. Menu plans, as well as individual food logs will be analyzed for nutritional value and compliance to an anti-inflammatory diet. Interviews will be subject to thematic analysis.
Finite $F$-representation type for homogeneous coordinate rings of non-Fano varieties
Authors: Mallory Devlin
Published: December 2023

Finite $F$-representation type is an important notion in characteristic-$p$ commutative algebra, but explicit examples of varieties with or without this property are few. We prove that a large class of homogeneous coordinate rings in positive characteristic will fail to have finite $F$-representation type. To do so, we prove a connection between differential operators on the homogeneous coordinate ring of $X$ and the existence of global sections of a twist of $(\mathrm{Sym}^m \Omega_X)^\vee$. By results of Takagi and Takahashi, this allows us to rule out FFRT for coordinate rings of varieties with $(\mathrm{Sym}^m \Omega_X)^\vee$ not ``positive''. By using results positivity and semistability conditions for the (co)tangent sheaves, we show that several classes of varieties fail to have finite $F$-representation type, including abelian varieties, most Calabi--Yau varieties, and complete intersections of general type. Our work also provides examples of the structure of the ring of differential operators for non-$F$-pure varieties, which to this point have largely been unexplored.

Social and Emotional Learning: A Literature Review from Islamic Perspective
Authors: Ali Sami
Published: December 2023

Through the process of social and emotional learning (SEL), both adults and children can learn the abilities needed to comprehend and control their emotions, form wholesome relationships, and make moral decisions. From an Islamic standpoint, social and emotional learning is regarded as a vital part of a comprehensive education since it aids in the development of the moral and ethical compass required to lead a happy and purposeful life. This paper aims to examine SEL from an Islamic perspective through the relevant scientific literature. The advantages of SEL for people as individuals, families, and communities are also covered in the review. Growing attention has been shown in the application of SEL to enhance character education in recent years. Through the SEL process, both adults and children can learn the skills needed to recognize and control their emotions, form wholesome relationships, and make moral decisions. It is a comprehensive method that takes into account the behavioral, affective, and cognitive facets of learning. The study of Islamic principles, practices, and beliefs is included in the wide field of Islamic religious education (IRE). It is a crucial component of many Muslim children's and youths' education. Since IRE instills in pupils the value of honesty, compassion, forgiveness, and other virtues, it can be a potent instrument for fostering character development.

Objective: Myeloproliferative neoplasms (MPN) are occasionally associated with autoimmune manifestations. The prevalence of positive direct antiglobulin test (DAT) in patients with JAK2V617F mutation is not yet known.

Methods: We conducted a cohort study of all consecutive patients with JAK2V617F mutation who underwent DAT at presentation from 2010 to 2022. We also looked for the prevalence of autoimmune diseases (AIDs) and relation to thrombosis.

Results: Fifty nine patients formed the cohort, 22 females and 37 males, with a mean age of 65 years. The median follow-up time was 90 months. A positive-DAT was found in 6 to 7% of essential thrombocythemia (ET) and polycythemia vera (PV) patients, 60% of primary myelofibrosis (PMF) patients and 50% of myelodysplasia/myeloproliferation (MDS/MPN) patients with or without anemia. Autoimmune manifestations were present in 13% of patients with PV and 50% of those with MDS/MPN features. Overall, 25% of patients had autoimmune phenomena including the 15% with positive-DAT.

Conclusion: In patients with JAK2V617F mutation, those with PMF and MDS/MPN subtypes are most likely to display a positive-DAT results and autoimmune manifestations (≥ 50%). Patients with PV and ET are less likely to exhibit autoimmune manifestations (≤ 10%). No correlation with the occurrence of thrombosis was seen.

Published: December 2023

En-route Flight Information (EFI) is a science that studies the procedures for guiding aircraft in uncontrolled airspace. With the development of teaching aid technology, digitizing the EFI learning system in the form of a website-based TopSky Simulator is expected to make it easier for cadets to understand the concept of EFI learning about providing advisory and surveillance services in Uncontrolled Airspace. The deepening of EFI learning material is very necessary as a preparation for cadets before carrying out On the Job Training which must be undertaken by cadets of the Surabaya Aviation Polytechnic to carry out field work practices as an application of knowledge, especially in fields that have been studied during class education both in theory and practice. Therefore, the author intends to develop learning support facilities, especially the En-route Flight Information course by making this TopSky Simulator website. It is hoped that the information system and the features available in it can help teachers and cadets in learning flight traffic control via radar and practicing it well in the field

Published: December 2023

This plan is motivated by the results of observations regarding the teaching and learning process for Cadets of the Surabaya Aviation Polytechnic, during the run-up and refueling practicum processes. This tool is planned to overcome the inefficiency of the refueling equipment in the Surabaya Aviation Polytechnic hangar, because when cadets do refueling it is not accurate to calculate the fuel that has entered the plane. In making this tool, applying microcontroller technology to a flow meter with a digital display by utilizing Arduino as a fuel flow measurement controller and for a flow meter sensor which functions to calculate the flow of fuel flowing through the tool, the results of the fuel meter measurements are then processed by Arduino which has been Fill in the program then the results are displayed on the LCD display.
