Differential Signs of Verbal Phraseological Units of the Belarusian Language with the Meanings of Activity and Relationship
Authors:   Yanka Kupala State University of Grodno, Marsheuskaya Valiantsina V.
Published: January 2024

This article deals with the formal and semantic properties of verbal phraseological units with the meanings of activity and relationship in the Belarusian language. The key research method applied here is descriptive, followed by the comparative and analytical methods. The author established that the subject of verbal units with the meaning of activity can only be a person (a group of people), an active doer of a certain activity who consciously and purposefully carries out this activity. In verbal phraseological units with the meaning of relationship, the subject and object are participants in an interaction (they can be a person, an inanimate object or an abstract concept). Changes in the subject-object environment can lead to the transformation of meaning and the development of polysemy of verbal phraseological units. As a rule, the object of verbal phraseological units with the meaning of specific activity is a product of an activity; however, many units are objectless. Verbal phraseological units with the meaning of abstract activity reflect the mental and speech activity of the person subject (human) and are mostly objectless. The subject of verbal phraseological units with the meaning of relationship is not an active doer of an action aimed to create (or destroy) an object (product of activity), but is characterized, first and foremost, by a relationship to a person or an object. The author has established that the phraseological units with the meaning of relationship can be divided into four groups: 1) interpersonal (interaction between people or groups of people), 2) person–object (relationship of a person to an object) 3) object–person (an object’s influence on a person) and 4) interobject (certain dependencies between objects). In the Belarusian language, рhraseological units with the meaning of interpersonal relatioship prevail. The results obtained can be implemented in the practice of teaching phraseology in higher education institutions and schools as well as in the theory and practice of phraseography.

Published: January 2024

This article turns to the relationship between the Bashkir Autonomous Soviet Socialist Republic (ASSR) and the Ukrainian Soviet Socialist Republic (SSR) to demonstrate the solidarity of Soviet peoples and regions during the Great Patriotic War. This period was a gruelling test of strength and unity for the fraternal peoples of the USSR. Special attention in the study is given to the role of the workers of the Bashkir ASSR in the restoration of the national economy of the Donbass, liberated from the Fascist occupation. Little-studied archival documents are introduced here, covering the extent of the aid, including social assistance, provided by the people of the Bashkir ASSR to the affected territories (machinery and building materials, industrial equipment, livestock, food and consumer goods). It is noted that during the harsh war years, the best qualities of Soviet peoples were drawn forth, which have enduring significance and stay relevant today: solidarity, cooperation and selfless mutual aid, which made an important contribution to the victory. In addition, it is argued that the aid to the liberated regions strengthened the economic and political unity of Soviet society and laid the foundations for the country’s successful post-war reconstruction. The research is based on documents from the National Archives of the Republic of Bashkortostan, which keeps an extensive body of invaluable sources on the history of the relationship between the peoples during the Great Patriotic War (materials on the evacuation of factories and scientific and cultural institutions as well as the population of the Ukrainian SSR, on launching the evacuated industrial plants in the Bashkir Autonomous Soviet Socialist Republic, on the cooperation between Ukrainian and Bashkir scientists, writers and cultural figures, as well as on the aid of Bashkir workers to the liberated territories of the Ukrainian SSR).

Authors: Gunjan Shukla  , Namrata Srivastava  , Kalpana Jain  , Kartik Chhonker
Published: January 2024

Background: Pilates Method as been a popular background for almost a century and is now used worldwide as a form of fitness and holistic health because it can be tailored to individual needs and fitness levels. Lucia first advised mat exercises performed on the floor, adapting them to individual physical and temporal constraints without compromising the wider element. He later labeled a series of specialized devices, including springs and rollers, that provide resistance to develop divergent movement patterns.13Performing exercise with medium intensity has positive effects on the maternal health. The goal of obstetriccare is to provide the right conditions for a safe delivery and make it a pleasant experience. Labor pain is anunavoidable component ofchild birth whose proper management, despite the great advances in midwifery, is still one of the major challenges related to women’s health. Pregnant women should also be clinically evaluated before starting exercise to ensure there is no medical reason to stop exercising.Methods:Patients were randomly divided into two groups of 15 people in each group. In the intervention group,a Pilates exercise program was developed in collaboration with a Pilates trainer. The program was tailored to the susceptibility of pregnant women and was administered twice weekly for 8 weeks.Four tools were used in this study, including a two-part checklist, the Borg Rating of Perceived Exertion (RPE),the Visual Analogue Scale (VAS), and the McKee Childbirth Satisfaction Rating Scale. A two-section checklist was used in this study to collect the required information.Conclusion:, According to the results of this study, Pilates exercise during pregnancy is a safe method to reduce the length of the active phase and second stage of labor, reducelabor pain, and increase maternal satisfaction with the child birth process. However, Pilates exercise did not significantlyreduce the need to episiotomy and caesarean section.

Authors: Dnyaneshwari K. Bhongade  , Amrita Sakharwade
Published: January 2024

Background:Computer work often involves both physical and mental demands. The physical demands are characterizedby low-force exertions and static postures that are sustained for long durations. Elevated shoulder postures,prolonged static contractions and the task duration have been identified as computer-related risk factorsfor neck and shoulderproblems, so this is responsible for development of trigger points particularly in the uppertrapezius muscles in forearm-unsupported computer operators as compared to forearm-supported.The uppertrapezius (UT)is designated as a postural muscle and is highly suspected ofoveruse because it works constantlyagainst gravity to maintain an erect head and neck position. This studyaims to identify upper trapezius triggerpoints (TrPs) developed with or without forearm support (FS) in computer operators.Materials and Methods: The study took place in the worksite of computer operators in Nagpur,Maharashtra for1.5 year. With a power of 90 and significance error of 1%, a total of 40 patients were taken according to the convenientsampling and divided into two categories computer operators Group A: with FS and Group B: without FS,following signs and symptoms like Trigger point, posterolateral neck and upper back pain most common in which group assessed by using, VAS (Visual Analogue Scale) for measuring pain intensity, Trigger Point Rating Scale is used for myofascial screening. Neck Disability Index for assessing the neck-related disability due to pain taken.Result: The study was conducted on 40 people, in which 20 people with forearm support and 20 people withforearm unsupported. The result is that forearm support reduces the load on the UTand also reduces the risk ofdevelopment of upper trapezius TrPs as compared to the forearm unsupported.Conclusion: Based on the results of these studies, it has been concluded that the development of UT TrPsincomputer operators without FS is more common as compared to FS.
“Urgência de um corpo livre do seu enredo”: a Ninfa e o tempo na poesia de Tatiana Faia
Authors: Genelhu Fagundes Mônica
Published: January 2024

Este artigo propõe uma leitura de dois livros da poeta portuguesa Tatiana Faia – Leopardo e abstracção (2020) e Adriano (2022) – reconhecendo aí aparições da figura da Ninfa, estudada por Aby Warburg e retomada por Georges Didi-Huberman como alegoria teórica que mobiliza um pensamento desestabilizador sobre o tempo e sua lógica. Insistente e fluida, reincidente e metamórfica, a Ninfa atravessa a história da cultura, criando dobras entre tempos e entre textos, promovendo cruzamentos críticos do passado e do presente. Gesto reflexivo que parece especialmente caro para uma poeta contemporânea que também se dedica aos estudos clássicos.

Memórias em luto, vozes subjugadas: o silêncio materno na narrativa de Hatoum e Lobo Antunes
Authors: Prevedello Tatiana
Published: January 2024

Neste estudo buscaremos aproximar algumas linhas hermenêuticas dos romances Relato de um certo Oriente (1989), de Milton Hatoum, e Ontem não te vi em Babilónia (2006), de António Lobo Antunes. Em ambas as narrativas, a maternidade de duas personagens é marcada pelo silêncio acerca da identidade paterna e pelo destino trágico, que vitima as filhas de ambas as mulheres: Soraya Ângela, a menina surda-muda no romance de Hatoum, morre na infância em decorrência de um grave acidente; a filha inominada de Ana Emília, no enredo loboantuniano, comete suicídio aos quinze anos. Neste âmbito, pretendemos adentrar-nos em mecanismos memorialísticos que configuram a forma como as duas mães ficcionais, construídas sob os auspícios do silêncio, são representadas no embate com a ausência paterna, a tragédia e a morte.
Escuro, de Ana Luísa Amaral: poesia em rizoma
Authors: Antunes Susana L. M.
Published: January 2024

O presente artigo propõe uma leitura crítica do livro Escuro (2014), de Ana Luísa Amaral, a partir da perspetiva filosófica da noção de rizoma proposta por Gilles Deleuze (1925-1995) e Pierre-Félix Guattari (1930-1992). Neste sentido, as multiplicidades cruzadas pela diferença do pensamento num jogo permanente e dicotómico presente em Escuro possibilitam a horizontalidade da poesia que se movimenta na força da delicadeza subterrânea do rizoma que se multiplica diferencialmente. Pela arquitetura corporalizada na multilinearidade de diferentes rotas de leitura, Escuro é perspetivado a partir da análise dicotómica e rizomática que enforma a rede conceptual deleuze-guattariana.
A (i)mobilidade narrativa em O ano da morte de Ricardo Reis, de José Saramago
Authors: Gonçalves Adriana
Published: January 2024

O ano da morte de Ricardo Reis, publicado em 1984, ficcionalizará a morte daquele que é, por excelência, uma figura da ficção. Durante a narrativa, interessam-nos as diferenças existentes entre a figura do heterônimo pes­soano e a reprodução dele na obra de Saramago no que diz respeito à certa (i)mobilidade. As relações simbólicas construídas por Saramago entre o personagem-heterônimo e o poeta (também ficcionalizado) e, especial­mente, dele com as figuras femininas, afetarão diretamente sua movi­mentação na narrativa.

O Retorno de Dulce Maria Cardoso: a memória alterizada ou as sobras do Império
Authors: Cerdeira Teresa Cristina
Published: January 2024

O Retorno, de Dulce Maria Cardoso, é um romance que se inscreve nesse quadro bem específico de “narrativas de retornados”. No avesso das me­mórias da conquista e da colonização, a viagem de retorno ao Portugal continental deixou um saldo dramático em quem vivenciou essa forma peculiar de desterro. Porque, a bem dizer, o termo “retornado” era muitas vezes uma etiqueta ilegítima, já que grande parte dos jovens portugueses da segunda ou terceira geração de colonos em África nunca lá tinham es­tado e, para eles, Portugal se limitava ao conhecimento abstrato da Histó­ria nacional que a escola lhes transmitia. Dulce Maria Cardoso, em 1975, era um desses retornados.

Published: January 2024

Human resources are an important asset in an organization. One way to retain employees in an organization requires increasing Employee Engagement, workload, and job satisfaction with employee performance. This research aims to identify key factors that influence employee performance from a subjective point of view and investigate how POB indicators and DCS aspects are reflected in employee experiences. This research design uses a qualitative method with a case study approach, research data is collected through in-depth interviews with employees so that conclusions can be obtained as a result of the research. The results of this research indicate that Employee Engagement has important value in improving employee performance. Employees who feel involved, have control in carrying out their work and feel valued by the organization tend to be more motivated and committed to making maximum contributions. On the other hand, excessive workload can have a negative impact on employee performance, causing stress, fatigue, and decreased productivity. However, if the workload is balanced with adequate control, optimal performance can be achieved. Job satisfaction plays an important role in improving employee performance. Employees who feel satisfied with their jobs tend to be creative, innovative and have a high level of commitment to the organization. The implication of this research is that it is important for organizations to develop strategies that enable employees to feel involved, overcome high workloads, and feel satisfied with their work so that they can improve the performance and services provided to JKN participants.

Large eye–head gaze shifts measured with a wearable eye tracker and an industrial camera
Authors: Hooge Ignace T. C. , Niehorster Diederick C. , Nyström Marcus , Hessels Roy S.
Published: January 2024

We built a novel setup to record large gaze shifts (up to 140$$^\circ $$

∘

). The setup consists of a wearable eye tracker and a high-speed camera with fiducial marker technology to track the head. We tested our setup by replicating findings from the classic eye–head gaze shift literature. We conclude that our new inexpensive setup is good enough to investigate the dynamics of large eye–head gaze shifts. This novel setup could be used for future research on large eye–head gaze shifts, but also for research on gaze during e.g., human interaction. We further discuss reference frames and terminology in head-free eye tracking. Despite a transition from head-fixed eye tracking to head-free gaze tracking, researchers still use head-fixed eye movement terminology when discussing world-fixed gaze phenomena. We propose to use more specific terminology for world-fixed phenomena, including gaze fixation, gaze pursuit, and gaze saccade.
Cultural practices as a form of active cultural consumption
Authors: Oliinyk Oleksandra
Published: January 2024

This paper focuses on the influence of passive and active cultural practices on the processes of inculturation and socialization. Despite the various attention to cultural practices (and cultural consumption), there are a number of different interpretations, which are based on the basic perception of the interaction of the cultural producer with the consumer, and, accordingly, the proactive involvement of the consumer in the cultural life. The article examines the hypotheses of cultural practices that form the modern thesaurus of cultural theory, using relatively recent data on cultural practices in Ukraine. The basis of the conceptualization of cultural practices in the study is the perception of cultural producer-consumer relations as a system of access to resources and goods, where cultural consumption is determined by access to cultural goods, and the level of involvement (participation) in cultural consumption is distinguished as active and passive.
Particular attention in the research is paid to the functions of cultural practices, in particular as a potential tool for revitalizing the socio-cultural and economic life of cities. The significance of the self-organizing potential of cultural practices, in our opinion, is most clearly traced in the studies of urbanists and social geographers, whose theoretical and practical theses indirectly deduce how — even if hypothetically — cultural consumption and cultural practices affect changes in society, and how society ultimately changes cultural practices.
Formation of individuality of a jazz performer: theoretical and practical aspects
Authors: Vinarikov Danylo
Published: January 2024

The experience of leading musicians and composers played a key role in the formation of jazz art. They invented not only new ways of improvisation, but also new styles, genres, and forms of jazz, created educational institutions, and launched festivals and competitions that helped young jazz performers develop their sound and be competitive. In the twenty-first century, such a specific quality as the individuality of sound is becoming a central feature of individual and collective jazz practices. To achieve it, jazz performers should use previous historical experience, and have certain theoretical knowledge and understanding of the laws of jazz performance. The article proves the necessity of combining theoretical and practical knowledge that should be used by a jazz performer, ensemble leader, or jazz orchestra conductor to develop an individual style of sound and work with a jazz band.
The relevance of study of visual identification of the Olympic ceremonial costume of the national team of Ukraine: the question of cultural expansion
Authors: Mykhailova Tetiana
Published: January 2024

The issue of national identity, in particular visual identification, requires considerable attention in the direction of the conformity of the declared sign or their combinations. Certain signs and their compositions influence the social perception of the information consumer, correcting the already existing opinion about the communicator at the stage of his or her development of relations with the recipients. Vestimentary code of ceremonial costume in projects of international cooperation is a component of illustrative representation of states, peoples or nations. These and other specified reasons determine the importance of scientific and applied research on the Olympic ceremonial costume of the national team of Ukraine, that is, a versatile study of the relay of cultural codes, meanings and ideas of a nation that participates in competitions covering millions of audiences of various representations.

Within the framework of the study of the Olympic ceremonial parade costume of the national team of Ukraine 1994– 2022, its symbolic system and aspects of the transformation of the determinants of artistic and informational identification are comprehensively studied in accordance with the semiotics of design, national constructs, globalization requirements and the provisions of the Olympic Charter.

This work determines the relevance of the study of the visual identification of the Olympic ceremonial costume of the Ukrainian national team and the role of the cultural expansion of russia, which was the result of the symbolic uncertainty of identification at world competitions.
The goddess of Moon in archaic symbolism and folk ornaments (about symmetrical seven-and three-membered structures)
Authors: Prychepii Yevhen
Published: January 2024

Insight into the semantics of symbols and ornaments that conveyed the cycle of the Moon is important for understanding the worldview of people of the Stone Age. The purpose of the article is to identify the symbols that conveyed the cycle of the Moon and establish their semantics. The structural method was used in the research. The author’s concept is outlined, according to which the cycle of the Moon in ancient times was conveyed by a three- and seven-member structure of symbols, which was characterized by a symmetrical arrangement of symbols and the combination of three or seven symbols into a single whole. A number of symbol structures on the ceramic products of the Trypilians and on the artifacts of other early farmers of Old Europe, which can convey the cycle of the moon, have been analyzed. Similar three- and seven-membered structures were found in the ornaments of Podillya towels. It is shown that the concept of three- and seven-membered structures of the symbols of the cycle of the Moon can be the key to insight into the semantics of many structures of archaic symbols and ornaments, and can also serve to explain the origin of triads of goddesses (like the three Moiras, etc.) in mythology.

Authors: Alhasani Reem
Published: January 2024

Aim: Our goal in this work was to investigate Chenopodium ambrosioides bioactive profile as well as its in vitro antidiabetic, neuroprotective, and antioxidant properties.
Methods: The antioxidant capacity of Chenopodium ambrosioides extracts (CAE) was assessed by using four complimentary tests: 2,2-diphenyl-1-(2,4,6-trinitrophenol) hydrazyl (DPPH), ferric reducing antioxidant power (FRAP), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and total antioxidant capacity (TAC) assays. α-Glucosidase, acetylcholinesterase, and butyrylcholinesterase inhibition assays were used to assess the antidiabetic and neuroprotective potential of CAE.
Results: According to the assay findings, CAE exhibited considerable antioxidant activity and a high concentration of proanthocyanidins, flavonoids, tannins, and total phenols. CAE showed significant total antioxidant activity (EC50 106.51 µg/mL) in comparison to the ascorbic acid (EC50 76.34 µg/mL). There is no as such significant difference between the inhibitory effects of CAE towards α-glucosidase (IC50 27.5 µg/mL) in comparison to acarbose (IC50 39.3 µg/mL), however CAE showed considerable inhibition to acetylcholinesterase (IC50 29.3 µg/mL) and butyrylcholinesterase activity of (IC50 57.8 µg/mL) as compared to the standard drug galantamine (IC50 53.6 µg/mL).
Conclusion: These results suggest that based on the antioxidant and enzyme inhibitory potential, CAE could be used as a natural remedy for the treatment of diabetes and neurodegenerative disorders.

Finite Element Analysis of the Main Structure for a New Conceptual Aircraft Passenger Vertical Seat Design
Authors: Fairuz Izzuddin Romli  , Norhafizah Mohamad Dasuki  , Mohammad Yazdi Harmin
Published: January 2024

Standing cabin is a new design concept of aircraft passenger cabin whereby passengers are transported in the standing position throughout flight as opposed to current seated position. An important element of this cabin concept is the design of the vertical seat to support the passengers, which has to be in compliance with requirements of aviation regulation. In commercial aircraft applications, weight of passenger seat is a significant factor that can affect flight performance of the aircraft. Meanwhile, the seat’s structure should have adequate strength to ensure proper safety provision to passengers. Hence weight and strength are potentially two conflicting design requirements for the vertical seat, and the optimum structural design should have the best compromise with regards to these two requirements. In this study, parametric study on primary structural design of the proposed vertical seat concept is done to obtain an optimized design that satisfies the strength requirements for safety of passengers without causing high penalty to the overall aircraft weight and performance. The simulation analysis for the main structures of the vertical seat design is conducted through finite element method using ABAQUS software. From the results of the analysis, main structural parts made from aluminium alloy with diameter 90 mm and thickness 3 mm are selected for the optimum vertical seat design. This standing seat design has also been shown to have adequate strength and can satisfy the safety regulation requirement without failure. The maximum stress on the seat’s structure under 9-g forward loading is found to be 147.5 MPa, which is lower than ultimate strength of aluminium. Moreover, the seat’s weight is estimated to be 9.5 kg and the maximum deflection of its main structures under forward 9-g loading is 28.42 mm. All in all, the stress analysis results highlight that the structural strength of the optimal vertical seat design can satisfy the requirements of the governing aviation regulations to provide safety to passengers.
Enhancing Strength and Impact Resistance of Latex Rubberized Concrete through Steel Fiber Incorporation
Authors: Siong Kang Lim  , Le Yi Eng  , Jee Hock Lim  , Ming Kun Yew  , Yee Ling Lee  , Ming Han Lim
Published: January 2024

Rubberized concrete, which incorporates crumb rubber, offers improved impact resistance, toughness, and ductility compared to regular concrete. However, its strength is typically lower due to weak interfacial transition zones (ITZ) between the crumb rubber and hardened cement paste. This study aims to investigate the potential of steel fiber and SBR Latex in compensating for the strength reduction caused by the inclusion of crumb rubber. Specifically, the research focuses on the effect of incorporating steel fiber into latex rubberized concrete (LRC) on compressive strength, flexural strength, splitting tensile strength, and impact resistance. To determine the optimal mix proportion, trial mixes of LRC and Latex-based rubberized concrete with 15 kg/m3 steel fiber (LRC-15% SF) were tested for their compressive strength, splitting tensile strength, flexural strength, and impact resistance. The selected mix proportion had achieved a minimum of 55 Mpa of 28-day characteristic strength. Experimental results indicated that the inclusion of steel fiber led to improved strength properties in LRC. The optimal LRC-15% SF mixture, with a water-to-cement (w/c) ratio of 0.28, outperformed the control mix (w/c ratio of 0.28) by 3.18%, 10.70%, and 17.94% in compressive, splitting tensile, and flexural strengths, respectively, at 56 days. Additionally, the LRC-15% SF exhibited higher impact resistance, showing a 46.27% and 14.71% increase in the 400 mm and 200 mm span length impact tests, respectively, at 56 days.

This study examines the unsteady Fe3O4-CoFe2O4/H2O flow over a shrinking disk using both procedures (numerical and statistical). The respective boundary layer model is first transformed into a set of ODEs (ordinary differential equations) using the similarity transformations, and then solved numerically using the bvp4c solver. The duality of solutions is presented within specific use of the parameters such as magnetic field, suction strength and volumetric concentration of hybrid nanoparticles. From the numerical results, the velocity profile increases as the suction and magnetic parameters slightly increase. However, the temperature profile shows a reverse trend as compared to the velocity profile. Meanwhile, the justification of present physical factors (magnetic parameter, suction parameter) whether they are significant or not on the development of responses is tested using the RSM with the fit general linear model in Minitab. In addition, the generated response equation is also beneficial in predicting the flow and thermal distributions of this working fluid for other values of the emerging parameters.

Wood has found widespread use in various applications, however, this extensive usage has resulted in adverse environmental effects, such as contributing to global warming. To mitigate these impacts, there is potential in utilizing reclaimed spent bleach earth (SBE) as an alternative source for biocomposite materials. While polylactic (PLA) polymer is biodegradable, it exhibits limited mechanical properties. This study aims to explore the feasibility of incorporating SBE into polymer matrices. Different filler loading percentages for the PLA/SBE composite (0 wt.%, 10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.%) and extruder temperatures (170°C and 180°C) were considered. The SBE powder underwent characterization using techniques including Particle Size Analysis (PSA), X-Ray Diffraction (XRD), and Field Emission with Energy Dispersive X-Ray (FESEM-EDX). Characterization data revealed that SBE particles ranged in size from 40.24 μm to 51.37 μm and exhibited a crystalline structure. Density of the SBE/PLA composite directly correlated with composition, whereas tensile strength and Young's modulus displayed an inverse relationship. Moreover, varying the temperature by 10°C did not result in significant property changes. The connection between properties and SBE filler loading was evident through alterations in density and Young's modulus values. Furthermore, the composite's behavior shifted from ductile to brittle. Examination of surface fractures through fractography established a link between composite properties, filler loading, and temperature. Images of all samples displayed well-dispersed structures without significant voids. In conclusion, ANOVA analysis indicated that filler loading significantly impacted strength properties. These findings serve as a valuable addition to the existing database, which is currently limited in its coverage of SBE/PLA polymer composites, particularly in applications like packaging.

This research focused on wear analysis by using the coefficient of friction (COF) and high-speed CNC turning machine against ceramic cutting tools made from 80 wt.% Al2O3 - 20 wt.% ZrO2 mixed with 0.2 - 0.8 wt.% Cr2O3. The results showed that the sample with a composition ratio of 80 wt.% Al2O3 – 20 wt.% ZrO2 – 0.6 wt.% Cr2O3 demonstrated the lowest coefficient of friction of 0.305. In terms of tool wear, this cutting tool showed uniform abrasion marks on the flank wear, resulting in 60% - 80% better tool life compared to Al2O3 and Al2O3-ZrO2. Based on the observation by using SEM, analyses showed that grains were tightly bound to each other at a high cutting speed of 350 m/min and with a feed rate of 0.175 mm/rev, compared to Al2O3 and Al2O3- ZrO2 which showed visible chipping and notch. The addition of 0.6 wt.% Cr2O3 on Al2O3-ZrO2 composition was enough to increase the strength and reliability against ceramic cutting tools for machining purposes.

This research delves into the distinct wear scar properties exhibited by pure nickel and nickel composite coatings with varying concentrations of fly ash when sliding against a stainless steel ball on an aluminium alloy 6061 (AA6061) substrate. The composite coatings were formulated from a modified nickel Watt's bath using an electrodeposition technique, involving a 1-hour process at 40°C and a current density of 5 A/dm². Through experimentation utilizing a high-frequency reciprocating rig (HFRR) tester, the resulting composite coatings underwent assessment, capturing the features of the scar surfaces. Notably, the Ni-FA (nickel-fly ash) composite coating, comprising 90 g/l of fly ash, demonstrated notably enhanced wear resistance in contrast to both the pure nickel coating and the Ni-FA composite coatings with lower fly ash concentrations. The disparities in morphology between the pure nickel and Ni-FA composite coatings were discernible through scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDS), and analysis of surface roughness on the wear scars. These distinctions can be attributed to the varying impacts of fly ash concentration on the wear scar characteristics.

In basketball, it is crucial to understand the optimal shooting pattern for each individual in terms of gender and shooting distances from the basket. However, incorporating biomechanics shooting analysis quantitatively into the learning process is not preferable. Hence, the purpose of this study is to determine the quantitative aspect of basketball shooting for biomechanics analysis using the OpenPose motion capture system. This marker-less motion capture system generated the biomechanical parameter data subjected to a significant difference test for shooting performance. A total of four players – two males and two females, divided into two levels (intermediate and novice) performed ten continuous jump shots from two different shooting distances (4.57 m and 6.40 m) from the basket. Each individual’s biomechanical parameters were tested in a statistical or independent t test to determine which significant parameter has a measurable difference in shooting performance. When the effects of different body angles on missed to scored baskets were compared, only the right elbow angle (intermediate female player), the right shoulder angle (novice male player) and the left hip angle (intermediate female player and novice male player) showed a significant difference (p < 0.05) towards shooting performance. In the comparison of the velocity of right upper limb key points, only the velocity of the right shoulder (intermediate male player) showed a significant difference (p < 0.05) toward shooting performance. In conclusion, the findings of this study suggest that shooting analysis should be done quantitatively to demonstrate a more profound and clear understanding of biomechanics when considering an improvement in shooting performance.

This paper presents a numerical simulation approach using the finite element method (FEM) in ANSYS software to overcome the limited accessibility of laser soldering machines which are expensive. The study aims to examine the viability of simulating a laser soldering process using ANSYS steady-state thermal simulation. The simulation aims to produce accurate predictions for temperature distribution, heat flow, and deformation of the material during the process. A Gaussian laser beam equation is used to analyse the interaction between the laser beam and metallic components, particularly on PCB boards. This paper evaluates the properties of a laser beam and the Sn-3.0Ag-0.5Cu (SAC305) lead-free solders which are commonly used in electronic industries. As a result of the thermal analysis, the temperature distribution within the solder spots, as well as the copper as printed circuit board (PCB) can be determined, whereas the mechanical analysis of the materials can be determined by looking at their deformation and stress in the system. The results show that the laser beam effectively contains heat within the solder contacts, reducing the risk of excessive heat transfer. The copper acts as an efficient heat sink, managing thermal energy during the process. However, the solder point experiences substantial deformation and stress, indicating potential limitations in its performance. Nonetheless, the neighbouring components and solder joints exhibit a factor of safety, ensuring the overall safety and reliability of the system.
