A Study on Foreign Language Learning Anxiety Among English Major Students in Online Environments
Authors: Shams Muzhgan , Khosha Afifa
Published: June 2024

Foreign language learning anxiety is a common phenomenon among students, impacting their language acquisition and proficiency levels. English major students, particularly in an online setting, face unique challenges that can exacerbate anxiety levels. Understanding the factors contributing to this anxiety is crucial for designing effective language learning strategies and support systems. This study employed a mixed-methods approach, combining surveys and interviews to gather data on English major students' experiences with foreign language learning anxiety in an online environment. Participants were selected from various English programs, and data collection involved self-report measures and in-depth interviews to capture both quantitative and qualitative insights. The primary objective of this study was to investigate the prevalence and impact of foreign language learning anxiety on English major students in an online setting. By examining the factors contributing to anxiety and its effects on language learning outcomes, the study aimed to provide valuable insights for educators and policymakers to enhance online language learning experiences for students. Findings: The study revealed that while online English learning can reduce overall anxiety levels and improve listening and reading skills, it also leads to increased anxiety in communication tasks. Factors such as technology-related challenges, lack of face-to-face interaction, and performance pressure contribute to students' anxiety levels. Understanding these dynamics is essential for developing targeted interventions and support mechanisms to help students navigate and overcome language learning anxiety in online environments.

Mística como espelhamento de si no além-mundo:
Authors: Souza Nogueira Paulo Augusto
Published: June 2024

Neste artigo, perguntamo-nos pelo modelo de experiência mística que subjaz ao Martírio de Perpétua e Felicidade, uma narrativa em primeira pessoa das visões do além-mundo da jovem matrona cristã, Víbia Perpétua, antes de seu martírio junto a outros catecúmenos, em Cartago, em cerca de 204 d.C. Nos relatos, encontramos uma personagem que, diante da morte, desde sua posição liminar, visita o mundo do além – os céus e o mundo inferior – para interceder pelas pessoas e para contemplar a corte celeste. Esse modelo de mística não segue o padrão tradicional de mística entendida como conhecimento do sagrado transcendente que reverbera no interior do indivíduo. Antes, trata-se de uma mística em que o visionário se projeta no mundo com vistas à transformação, segundo o modelo da mística visionária apocalíptica. No relato do Martírio de Perpétua e Felicidade, no entanto, prevalecem as imagens concretas, as sensações físicas e as emoções. Nesse relato em primeira pessoa, o leitor antigo, em contextos rituais, era convidado a se unir ao “eu” narrativo e experimentava a transformação a partir das fronteiras do mundo dos mortos e dos vivos, em transições entre o macro e o microcosmo, nas inversões de gênero e de status social e religioso.
THE MODELLING AND ANALYSIS OF TEMPERATURE-DEPENDENT SILICON AND SILICON CARBIDE-BASED POWER DEVICE PERFORMANCE FOR HIGH-VOLTAGE APPLICATIONS USING MACHINE-LEARNING APPROACHES
Authors: POOBALAN BANU , Hashim Nuralia Syahida , Natarajan Manikandan
Published: June 2024

This study has revealed that On-State-Drain to Source resistance RDS(on) is one of the most significant variables influencing the performance of silicon and SiC-based power semiconductor devices in high-voltage applications. The low RDS(on) of power devices helps to drastically cut energy usage, enabling customers to create greener systems and products that lower CO2 emissions. In SiC MOSFETs, low RDS(on) enables significant system size and power consumption reductions in a range of applications, including traction inverters for electric vehicles and switching power supply. This work analyses the characteristics of silicon (Si) and Silicon Carbide (SiC)-based power semiconductor devices’ performance in terms of total gate charge, drain current, power dissipation, thermal resistance and switching speed. This work affirms that SiC-based power devices provide superior performance as compared to silicon power devices for the abovementioned parameters at the same voltage rating of 650 V. The study highlights the effects of RDS (on) on Si and SiC-based power devices and provides insight into the predictive modeling of the analyzed parameters at elevated temperatures, which is a novel contribution to this field of research. The models and formulations generated from this work help the designers select the power devices with the required RDS(on) and correlate their effects by estimating the values of other important parameters, mainly, continuous drain current and zero voltage drain current at elevated temperature, with the exception of the real-time device testing procedure. The models and formulations generated using regression in this work are further validated using Mean Absolute Percentage Error (MAPE) and R2 techniques. The outcome of this work is expected to be implemented in the current machine-learning technology for device testing purposes.

The apple orchards with large land extensions represent a challenge in monitoring crops. Remote sensing techniques can analyze and obtain information on the general state of crops using multispectral data and vegetation indexes. This study aimed to analyze the flowering phenological of three apple orchards using images from Sentinel-2 satellite and a Phantom 4 pro/pro+ drone in three apple-producing regions. The images were processed using ArcGIS software and the Normalized Difference Vegetation Index (NDVI). The results were statistically analyzed through discriminant to classify and identify significant differences between the flowering phenological stages. NDVI maps were obtained for the study areas, and the NDVI values ranged from 0.09 to 0.26 and from 0.22 to 0.35 for drone and satellite images, respectively. It was possible to differentiate between two groups of phenological stages in the apple orchards (pre-bloom and post-bloom). The information generated can be a complementary tool for monitoring the apple tree crop.

Authors: Sobrinho Jodeylson Islony de Lima
Published: June 2024

Esse artigo de cunho teórico-crítico é um substrato dos resultados da nossa pesquisa de doutoramento em Serviço Social, na qual buscamos apreender o movimento das determinações que envolvem o avanço atual do conservadorismo e da “captura” da subjetividade profissional no âmbito do Serviço Social contemporâneo em detrimento do trabalho profissional de acordo com a cultura crítica da profissão, em tempos ultraneoliberalizantes. Munimos-nos do materialismo-histórico dialético como método de pesquisa e priorizamos como estratégia de investigação a análise e interpretação de dados bibliográficos, a partir da delimitação de 35 artigos publicados nos anais do XVI Congresso Brasileiro de Assistentes Sociais (CBAS) do ano de 2019. Para a análise do material selecionado, delimitamos as seguintes categorias analíticas: precarização do trabalho; trabalho profissional; projeto ético-político e crise do capital. De forma complementar, utilizamos fragmentos das entrevistas realizadas no âmbito da minha pesquisa de mestrado, tendo em vista que certas questões careciam de aprofundamento. Apresento, portanto, um dos elementos evidenciado na pesquisa que trata especificadamente de como a incorporação da racionalidade e das diretrizes institucionais, como fundamento do trabalho profissional, recai no contrassenso à cultura crítica do Serviço Social.
Benchmarking Llama 3 70B for Code Generation: A Comprehensive Evaluation
Authors: Ersoy Pınar , Erşahin Mustafa
Published: June 2024

This study benchmarks the capabilities of Llama 3 70B, a 70-billion parameter large language model (LLM), for code generation tasks. To effectively train and fine-tune this massive model, we integrate PyTorch Fully Sharded Data Parallel (FSDP) [1], [2] for distributed training and Quantized Low-Rank Adaptation (Q-LoRA) [7] for efficient fine-tuning. We address challenges associated with distributed training, including communication overhead and synchronization complexities, through optimization strategies like gradient accumulation, optimizer state sharding, and mixed precision training. Additionally, we employ advanced training techniques such as Curriculum Learning, Dynamic Batch Sizing, and Adaptive Optimization Algorithms to enhance model performance and training efficiency. Our primary focus is evaluating the performance of the fine-tuned Llama 3 70B model on two widely-recognized code generation benchmarks: HumanEval [8] and MBPP [9]. HumanEval assesses the model's ability to translate natural language problem descriptions into functionally correct code, while MBPP evaluates its proficiency in solving complex programming problems by generating accurate Python code. We present detailed performance results on these benchmarks, analyzing the model's strengths and limitations in various code generation scenarios. Furthermore, we compare the impact of our training and fine-tuning methodologies on scalability, memory efficiency, and training speed, demonstrating the feasibility and efficiency of our approach. This benchmark study offers valuable insights for researchers and practitioners exploring the application of LLMs for code generation. It provides a comprehensive evaluation of Llama 3 70B's capabilities, sheds light on the effectiveness of various training and fine-tuning techniques, and emphasizes the importance of rigorous benchmark evaluation in driving progress within this rapidly evolving field.

The power of abstract vs. the force of gravity – unusual constructions by Christian Kerez
Authors: Radwański Damian
Published: June 2024

The article seeks an answer to the question: what creates the unique nature of the design domain of Christian Kerez's projects, who for over 20 years has preferred the creation of experimental load-bearing systems to the processing of proven patterns and optimization of effective static models rooted in rational paradigms of the modernist period?This case study was conducted based on statements and interviews of the author of unusual solutions and on the basis of the analysis of his two lesser-known competition projects from 2008 - Holcim Competence Center in Holderbank and Swiss Re Next in Zurich.The conducted research shows that the creator perceives his objects in a purely conceptual way, each time through the prism of different, abstract rules that determine all domains of the building, including the structural one. The effects of the strategy developed by the Swiss are peculiar formal and structural solutions that stimulate unusual feelings of the observer, which in the analyzed projects seem to undermine even such a basic and obvious constant as the law of universal gravitation in an exceptionally suggestive way.

Digital image correlation technique versus traditional measurement methods on the example of fiber reinforced concrete tests
Authors: Blazy Julia , Drobiec Łukasz
Published: June 2024

Fiber reinforced concrete is characterized by the ability to transfer loads with increasing crack width, even after reaching the maximum load capacity. Therefore, it is necessary to observe and analyse the propagation and increase of the crack. For this purpose, the traditional measurement methods like clip gauges or linear variable displacement transducers can be used. However, the digital image correlation technique is increasingly gaining popularity as an alternative, supplementary or verifying measurement method. The article focuses on the comparative analysis of the results from direct measuring devices with the results from virtual sensors obtained in the three-point bending test and Montevideo splitting tensile test. Fiber reinforced concrete samples with three different types of polymer fibers and their different content in the concrete mix were tested
Analysis of the possibility of rectification of the wall of the historical barrack B-138 located in the KL Auschwitz-Birkenau
Authors: Gromysz Krzysztof , Szoblik Łukasz
Published: June 2024

The construction of the German Nazi concentration and extermination camp Auschwitz II – Birkenau started at the end of 1941. A barrack with the current inventory no. B-138, situated at the section BI, was then erected. The barrack has documentary and historical value. The barrack walls are characterised by low stiffness, because with the building’s plan of 36.3 m × 11.4 m, the walls are only 0.12 m thick. All the outer walls have been substantially deformed or vertically deflected. Up to 156 mm wide gaps have formed between the deformed and deflected walls and contiguous walls as a result. The stability of the walls is at risk, because a bad-quality wall was loaded with horizontal and vertical forces transmitted from the roof on the eccentricity reaching 160 mm. Deformations were progressing over time as a consequence of such forces. Individual rectification procedures is proposed. This article presents a procedure of handling the western gable wall. The deformation of the western gable wall will be removed by changing its static scheme, by inserting hinge regions into the wall along the line of selected bed joints. Separate wall patches, which could rotate relative to each other, will be created as a result of the forces acting perpendicular to the wall surface. By causing the mutual rotation of such patches, the western gable wall will the desired vertical position.The stability of such a system during rectification was analyzed and it was shown to be maintained. On this basis, it is concluded that the analyzed method of rectification of the wall is possible to implement. After the rectification, the joints of the transverse wall will be replaced, and the wall itself will be anchored to the longitudinal walls with the use of reinforcement embedded in the joints

The damaged viaduct functioned until 2014, when it was repaired and adapted to transfer considerable mining influences. In 2021, the viaduct was dismantled due to the reconstruction of the voivodship road running over it
Ultimate load-bearing capacity of samples made of self-compacting concrete placed inside composite pipes
Authors: Ostrowski Krzysztof , Sikora Oliwia , Furtak Kazimierz
Published: June 2024

In recent years, composite materials have been widely used to reinforce existing structures, including concrete elements. This process generally consists in gluing a carbon fibers (or other) mat to a previously prepared concrete surface, most often using epoxy resin. Making concrete structures – especially concrete columns – involves the need to make formwork and scaffolding systems and then demolding the elements. This process can be time-consuming, which affects the speed and cost of building a concrete column. This work proposes a method of preparing composite tubes from carbon laminates and their subsequent use as a lost mold for the production of cylindrical composite samples. Composite tubes with an average thickness of 0.3 and 0.9 mm were filled with self-compacting concrete and then subjected to destructive testing in the uniaxial compression test. The compressive strength of the concrete in the 0.3 mm (SCC-0.3) and 0.9 mm (SCC-0.9) pipe sheath was 37% and 95% higher, respectively, compared to the reference concrete. The average value of the maximum axial deformation was 0.0048, 0.0069 and 0.0151 for self-compacting concrete (SCC), SCC-0.3 and SCC-0.9, respectively. An increase in the modulus of elasticity was also noted for the concrete in the composite pipes. The obtained results showed good cooperation of the external reinforcement (composite tube) with the concrete core, despite the infinitesimal adhesion between these elements

Authors: Gil-Mastalerczyk Joanna , Mochocka Sylwia , Wijas Małgorzata
Published: June 2024

The multidimensionality of contemporary architectural design, from the conceptual to the execution stage, requires mandatory consideration at every stage of design and execution, of the needs of people with functional limitations, including seniors. The starting point for the design of architecture for seniors is the main principles of universal design formulated and developed by Ronald Mace since the early 1970s. Drawing on these theories, the article presents student visions of structures designed for seniors using workshop research techniques as part of the ongoing POWR “Accessibility Hub – centre for practical accessibility learning” (orig. Hub dostępności – centrum praktycznej nauki dostępności) Project and the research by design methodology. Linking the design process with scientific research has unleashed new possibilities for interpreting architectural solutions and has become an important source of new knowledge
Barriers and opportunities for implementing predictive maintenance of railway station buildings
Authors: Gajzler Marcin
Published: June 2024

The article discusses the possibility of implementing predictive maintenance of station buildings in terms of ensuring their reliability by maintaining proper technical condition without introducing restrictions on use. Basic building maintenance strategies were discussed, including the obligations arising from legal requirements. Based on observations of railway station buildings, it was found that there is no sufficient sensory infrastructure to fully implement predictive maintenance. In addition, potential possibilities of using solutions enabling the implementation of a predictive approach were considered. As an alternative, in particular a solution enabling the acquisition of information and data, an own approach was presented to support technical management based on predictive maintenance.
Opinions of users of the Poznan Metropolitan Railway in the light of survey research
Authors: Grabarczyk Agata , Pasławski Jerzy
Published: June 2024

The main aim of the article is to determine the requirements of agglomeration railway passengers in order to change transport habits. The focus was on the requirements for small railway stations, which play an important role in the process of implementing the idea of sustainable transport. Most travelers use their private cars for daily commuting. This is largely due to the neglect of public transport, which requires a fundamental change in policy – its focus on the development of sustainable transport, the pillar of which is rail transport along with non-motorized transport options (e.g. cycling, walking). The survey showed that the most important point of the survey were the problems that travelers face on a daily basis at railway stations/stops. The basic ones include: lack of toilets, waiting rooms, cafes/bars and commercial and service points. Development plans for the Poznan Metropolitan Railway (PKM) were also presented – a project to use the city's freight bypass in the PKM system. Its main goal is to bring the metropolis closer to the idea of a 15-minute city and 15-minute stations in order to achieve the concept of sustainable transport in the city and agglomeration. Due to the critical assessment of Innovative System Stations as a solution that, due to non-standard equipment, causes problems with significant costs of vandalism, it was proposed to introduce System Modular Stations based on flexibility, enabling – thanks to the introduction of the idea of modularity in the construction of a small station – adapting the station/stop equipment to the changing requirements of passengers. The flexible approach is based on staged investing, which also significantly reduces the level of initial investment expenses. The initial solution is to equip the station with basic equipment that meets the survey results. Naturally, the key to success in the design, construction and operation of small stations is cooperation between PKP, regional authorities and the local community.
Principles of determining remuneration of a court expert and opinions prepared by scientific and technical institutes in terms of case law
Authors: Bal Michał
Published: June 2024

The institution of a court expert is necessary for the proper functioning of the judicial system. At the same time, the lack of an appropriate number of experts, the problem of finding experts with appropriate qualifications, and especially remuneration, cause that court experts most often constitute a burden on the judicial system. The solution to this problem may be to increase the participation of experts by using the services of scientific institutes, universities, and scientific and technical associations. Their remuneration rules differ from those resulting from the regulations and apply to individual experts entered on the court list. The case law expands the possibility of freely shaping remuneration for institutions, but it contains certain threats that require special attention and ability to apply the law from the managers of these organizations. Undoubtedly, the benefits for the court system, but also for appraisers and the institutions themselves mean that, despite certain threats, this type of evidence should be particularly developed.

Highly significant variance due to genotypes revealed presence of sufficient variability for all the traits except number of seeds/pod (SP). Among the characters, high Hbs2 associated with high GA% were recorded in number of primary branches/plant (NB), plant height (PH) and 100-seed weight (SW). Path analysis revealed that, number of pods/plant (PP) (0.840) had the greatest direct effects in influencing seed yield/plant (SYPP), followed by biological yield/plant (BYPP) (0.795), number of seeds/pod (SP) (0.474), number of primary branches/plant (NB) (0.309) and harvest index (HI) (0.307). Correlation studies among root and shoot parameters under hydroponic studies revealed significant correlation between root dry weight (RDW) and shoot dry weight (SDW); shoot fresh weight (SFW) and root fresh weight (RFW); total root length (TRL) and surface area (SA); and haematoxylin stain score (STNS) and root regrowth (RRG). Based on mean performance of SYPP and attributing traits, combined with root growth studies under hydroponics, the high yielding and Al toxicity tolerant genotypes identified were LRIL-37, LRIL-22, LRIL-68, LRIL-96 and LRIL-97. In addition to serving as parents in hybridization programmes, these genotypes may undergo additional evaluation in multiple environments prior to final release in an effort to enhance performance.

Present study was carried out during rainy (kharif) season of 2022 and summer season of 2023 at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu to identify cotton (Gossypium hirsutum L.) genotypes with enhanced morphological traits to resist leafhopper [Amrasca (Amrasca) biguttula (Shiraki, 1912)] infestations. To achieve this, 5 distinct genotypes were selected as parents, generating 10 F1 hybrids using the half-diallel method. Field and polyhouse experiments were conducted over a 30–120 days-interval. Genotypes, environments, and their interactions (G × E) played a significant role in confirming resistance. Infestation levels varied throughout growth stages, with the highest at 60 DAS (days after sowing). Microscopy analysis revealed glandular trichomes (GTs) and more single-celled non- GTs (NGTs) with complex dendritic branches (2–8) on primary stem leaves. Negative correlations of trichome density, trichome length and gossypol glands with leafhopper populations in both environments suggested a deterrent role. Conversely, leaf thickness positively associated, indicating potential pest preference. Stepwise regression highlighted combination of morphological traits, significantly contributed to greater leafhopper resistance, rather than a single factor. These findings provide valuable insights for selecting and breeding resistant cotton genotypes against leafhoppers.

Present study was carried out during winter (rabi) seasons of 2021–22 and 2022–23 at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh to evaluate the terminal heat tolerance ability of 30 wheat (Triticum aestivum L.) genotypes using 8 heat stress tolerance indices. The results indicate that 12 genotypes showed low yield reduction as compared to average yield reduction. The stress susceptibility index (SSI) was observed as robust indicator for identifying heat-tolerant genotypes. Stress tolerance index (TOL) was observed crucial which reflects genotype's ability to maintain grain yield under terminal heat stress. Analysis of correlation revealed positive relationships between grain yield under normal and stress conditions, suggesting that best-performing genotypes under normal conditions also perform well under terminal heat stress conditions. Principal component analysis and biplot analysis further confirmed the importance of studied tolerance indices for identification of heat tolerance genotypes. PC1 was associated with yield potential and heat tolerance, while PC2 was associated with stress susceptibility. Based on analysis, genotypes, viz. DBW14, DBW90, HD2864, HD2932, HD2985, HS375, HUW234, RAJ4083, WH1021, WH1124, DBW71 and PBW757 exhibited higher terminal heat stress tolerance. Cluster analysis revealed two major clusters, cluster I contained 12 heat tolerant genotype while cluster II was consisting 18 heat susceptible genotypes. The SSI and TOL index were found promising indices for identification of heat tolerant genotypes of wheat.

A field experiment was conducted during rainy (kharif) seasons of 2019 and 2020 at ICAR-Indian Agricultural Research Institute, New Delhi to monitor the effect of precision nitrogen (N) and water management options on yield and nutrient acquisition in grain and straw of direct-seeded rice (DSR, basmati) (Oryza sativa L.). Experiment was conducted under two cultivation methods, in a triplicate split-plot design (SPD). The main-plots were allocated to 6 combinations of 2 DSR cultivation approaches, viz. growing DSR in ploughed land (CTDSR); and growing DSR without tilling the land (ZTDSR); and 3 water regimes [adequate water; water supply at 20% available soil moisture exhaustion (ASME); and 40% ASME + silicon (Si) supply @80 kg/ha]. Sub-plots had 3 N supply decisions, viz. 100% recommended rate of N (RRN: 150 kg/ha); NutrientExpert (NE) + leaf colour chart (LCC); and NE + soil plant analysis development (SPAD) meter-based N scheduling. Conventional till-direct seeded rice produced 1.9, 3.1 and 5.7% greater grain yield, grain protein content and protein yield, respectively, over ZTDSR; the respective improvement in grain N, P and K uptake was 5.9, 7.9 and 4.9%. Adequate water regime resulted in 11.5, 7.3 and 18.7% more grain yield, grain protein content and protein yield, respectively, over water supply at 20% ASME with concomitant enhancement in grain N, P and K uptake of 19, 24 and 23%, respectively. A significant improvement in grain yield (9.2%), grain protein (11.7%) content and protein yield (22.1%) was detected with NE® + SPAD meter- based N application over RRN; the N, P and K uptake in grain also spiked by 22.1, 42.1 and 31.7%, respectively. Hence, NE + SPAD-based N application and adequate water regime (irrigation at 72 h of drying of surface water) could be beneficial for improving yield and quality of both CA-based and conventionally cultivated DSR.

Oxidative enzyme activity in plants is affected by innumerable direct as well as indirect ways. Sowing dates, nutrients in the form of foliar sprays and pre-seed treatments are the most common paths that can enhance the activity of oxidative enzymes in plants. The present field study was carried out during rainy (kharif ) seasons of 2019–20 and 2021–22 at the experimental field of Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana to evaluate the seed quality and yield of cowpea [Vigna unguiculata (L.) Walp] affected by the date of sowing, foliar application and seed treatment. The experiment was laid out in split-split plot design (SSPD) having 3 sowing dates, viz. 30 March (S1); 30 May (S2); and 30 June (S3) and 3 different seed treatments along with control i.e. T0, Control (untreated seeds); T1, Captan @2 g/kg; T2, Vitavax @2 g/kg; and T3, Bavistin @2 g/kg, replicated thrice. Nutrient spray, viz. FS0, No spray; FS1, NPK (18:18:18) @2%; FS2, NPK (17:44:0)-Urea phosphate @2% and FS3, NPK (0:0:50)- Sulphate of potash @2% were also done at at 35–45 DAS (days after sowing) and 55–65 DAS. The results reported that delayed sowing time reduced the oxidative enzyme activity and thus affected the productivity of quality cowpea. Captan was observed to be the most efficient and preventive, seed treatment agent. Out of the three-nutrient spray NPK @18:18:18 resulted in the maximum oxidative enzyme activity. The best quality seeds having highest values of oxidative enzyme activity including Catalase, Peroxidase, Dehydrogenase and Superoxide Dismutase were harvested from captan treated seed of second sowing with two sprays of NPK (18:18:18).
