Refletindo a Condição da Mulher Negra na Formação Patriarcal-Racista do Brasil à Luz de Lélia Gonzalez
Authors: Andrade Rafael , Lucena Glaucia
Published: June 2024

O artigo pretende fazer reflexões acerca do artigo Racismo e sexismo na cultura brasileira da filósofa Lélia Gonzalez, no qual a autora aborda a tripla opressão raça-gênero-classe sofrida pela mulher negra como herança da formação patriarcal-racista da cultura brasileira. Ainda hoje, a mulher negra desempenha papéis definidos desde a colonização europeia, tais como: da mãe preta, doméstica e mulata, portanto, perpetuando e sustentando modelos e visões racista e de subserviência dela. Há também um sobrelevamento da ideia de família brasileira branca e bem-sucedida, haja vista o demérito racista sobreposto por narrativas perpetuadas do racismo estrutural. Ademais, com intuito de manter a superexploração da população negra no Brasil, especialmente das mulheres, foi criado o mito da democracia racial, logo, surge a (falsa) impressão de que todos os povos vivem de modo harmonioso, quando na verdade predomina a exaltação da cultura do colonizador, bem como o racismo enquanto sistema de exclusão. Nesse sentido, buscando entender os efeitos psíquicos do racismo e do sexismo na vida das mulheres negras, Gonzalez enfrentou nomes importantes do pensamento social brasileiro, como Gilberto Freyre e Caio Prado Jr., e recorreu a psicanálise para explicitar a lógica do desejo implícito no processo de subjugação dos corpos das afro-brasileiras. Ao lutar contra o lugar de subalternidade das mulheres não brancas, Gonzalez aponta rumo a um feminismo com identidade afro-latino-americana. Pensar filosoficamente a sintomática do racismo à brasileira, especialmente a figura da mulher negra, é importantíssimo, sobretudo, urgente. A metodologia que guiou a pesquisa foi teórico-bibliográfica. Os escritos de Gonzalez encontram confluências teóricas em Djamila Ribeiro, Suelí Carneiro, Alex Ratts, Carla Akotirene, entre outros autores e trabalhos científicos que reafirmam questões cruciais e reflexões filosóficas acerca dos temas supracitados.

Authors: Alain Michel , Paul Amado
Published: June 2024

This article describes various approaches that utilize computer vision and Lidar technology. These approaches include, but not limited to, vision-based algorithms such as the Faster RCNN model and AprilTag; and single shot detectors (SSD). In carrying out docking and recharging operations, the aforementioned approaches have shown varying degrees of success and accuracy. In order to make it easier for mobile robot systems to perform autonomous docking and recharging (ADaR) in industrial settings, this study presents a new method that employs vision and Lidar technology. In this study, we propose the YOLOv7 deep learning model to find charging stations. To further simplify docking with the specified wireless charging station, a Lidar-based approach is used to precisely modify the robot's position. An account of the assessment standards and training procedure used for the adjusted YOLOv7 model is provided in the results and discussion section. In this research, it was found that the model's 86.5% mean Average Precision (mAP) within the IoU range of 0.5 to 0.9 is evidence of its efficacy. In addition, the detection and identification of charging stations had an average accuracy rate of 95% in the studies conducted in real-world settings.
Navigation Techniques and Algorithms for Mobile Robots and Automated Guided Vehicles
Authors: Wajda Andrzej
Published: June 2024

Mobile robots are self-contained devices that can navigate and move around their surroundings. They observe their environment and create maps using different sensors such as lidar, Global Positioning System (GPS), and cameras. Automated Guided Vehicles (AGVs) are vehicles that can move independently utilizing different approaches such as underground cables, laser scanners, or GPS systems. This research investigates several navigation methodologies and algorithms used in AGVs and mobile robots. It focusses on the advantages of integrating lidar technology with other sensors as well as how it is used in local navigation techniques. We look at two motion planning techniques for obstacle avoidance: the Artificial Potential Field (APF) approach and the Vector Field Histogram (VFH) algorithm. Two effective techniques for finding the best routes are discussed: the A* algorithm and Dijkstra's algorithm. The various AGV types and their navigation systems (such as wired, guide, laser, vision-based, and gyro-based) are also examined in the study. Neural networks and fuzzy logic are investigated as AGV control techniques, with line following and obstacle avoidance as examples of their use. The study emphasizes how crucial precise and dependable navigation systems are to the effective and secure operation of mobile robots and AGVs.
As multifacetas da deficiência intelectual: mediações pedagógicas além da abordagem clínica
Authors: Macêdo Tatiane Porto , Garcia Dorcely Isabel Bellanda
Published: June 2024

O presente artigo, apresenta-se como um estudo teórico e reflexivo sobre as implicações das mediações pedagógicas frente ao processo de ensino e aprendizagem de estudantes com deficiência intelectual, como uma das formas primordiais de se trabalhar com o determinado alunado. Elencando seu meio social e cultural propiciadores frente a aprendizagem e desenvolvimento não apenas dessa peculiaridade, mas de todos que compõe o contexto da sala de aula, pois uma mediação pensada em prol de alguma deficiência ou déficit vem abarcar toda a conjuntura da sala de aula, podendo ser repensada e aproveitada de forma qualitativa a todos. Diante dessa proposição, elenca-se a determinada deficiência como uma das especificidades mais complexas quando se refere a inclusão escolar do público-alvo da educação especial. Assim, propõe-se refletir e intermediar ao processo de aprendizagem e desenvolvimento a partir das indicações histórica e sociocultural a qual o estudante está inserido, e não enfatizar os aspectos biológicos como provedores de mediações, o que acaba ocasionando práticas mecanizadas e repetitivas de ensino que não se acrescenta de forma produtiva ao desenvolvimento das funções complexas superiores. Apresentando-se como objetivo, intervir de forma materializada quanto as práticas de ensino através de mediações pedagógicas significativas aos estudantes mencionados.  A metodologia utilizada é de cunho teórica e fundamenta-se na Teoria Histórico-Cultural que tem como principal representante Lev Vigotski. Como resultado verificou-se a importância de enfatizar as mediações pedagógicas contextualizadas e significativas ao meio sociocultural e histórico dos estudantes e não elencar como ações a serem desenvolvidas ao conceito que a organicidade da deficiência apregoa, ocasionando maior limitação e retrocesso quanto a aprendizagem e desenvolvimento desse público em especial.

Published: June 2024

In the present work, the experiments carried out aimed at the study and development of a composite based on Fe-Cu-Ni-Sn-WC, with different additions of Boron Carbide. The obtaining of this metallic matrix is intended for the production of pearls, for application in diamond wires used in cutting ornamental rocks. Five compositions were used for the investigation: samples with 2% B4C, 4% B4C, 5% B4C, 8% B4C, and 10% B4C. Initially, rectangular geometry composites were obtained via hot pressing, they were sintered under the same temperature conditions (800°C) and pressure (34MPa). The obtained segments reached approximately 18.00 mm in length, width between 12.80 mm and 15.20 mm, and 3.00 mm in height. The samples were characterized by the mechanical bending test, which allowed the investigation of properties at room temperature, such as yield strength, ultimate tensile strength, longitudinal elasticity modulus, toughness modulus, and resilience modulus. The results showed that the mixture containing 2% B4C presented better overall results. The studies conducted here serve as a basis for the development of new research aimed at producing diamond matrices for use in cutting tools. The inclusion of B4C in Fe-Cu-Ni-Sn-WC composites for creating ornamental rock cutting tools not only enhances efficiency and sustainability in the industry but also promotes significant advances in scientific research and the training of new specialists.

Este artigo explora a complexidade da violência contra a mulher negra no contexto específico do Nordeste brasileiro, ressaltando a interseccionalidade entre gênero e raça como uma dimensão crucial dessa problemática. Inicialmente, são abordadas as origens históricas e estruturais da violência de gênero no Brasil, com ênfase na sua interligação com o racismo estrutural. Posteriormente, a análise se aprofunda na violência direcionada especificamente às mulheres negras, destacando as disparidades significativas em relação à violência letal e não letal que enfrentam. Ao se concentrar nos dados alarmantes da violência em face da mulher negra na região Nordeste, conclui-se, através do método dedutivo, que essa população enfrenta uma carga desproporcional de violência. Com isso, constatando-se a necessidade de abordagens políticas e sociais mais abrangentes e eficazes. Ao mergulhar nos dados alarmantes que retratam a situação da mulher negra no contexto nordestino, emergem conclusões inquietantes que apontam para uma carga desproporcional de violência suportada por essa parcela da população. Nesse sentido, a aplicação do método dedutivo revela de forma inequívoca a urgência de abordagens políticas e sociais mais abrangentes e eficazes, capazes de enfrentar de maneira efetiva essa complexa problemática. A falta de acesso a serviços básicos de saúde, educação e segurança amplifica ainda mais sua vulnerabilidade, tornando-as alvos fáceis para a perpetuação da violência. Portanto, qualquer esforço para enfrentar efetivamente a violência contra a mulher negra no Nordeste deve levar em consideração não apenas suas manifestações mais visíveis, mas também as estruturas profundas de desigualdade que as sustentam. Isso exige uma abordagem holística e interdisciplinar, que una esforços de diversos setores da sociedade para promover uma verdadeira transformação cultural e estrutural.

Published: June 2024

O setor do varejo encontra-se num período em que o tempo e a qualidade dos produtos são tão importantes quanto o dinheiro investido. Portanto, o controle e gerenciamento do estoque é fundamental para atender às exigências atuais do mercado. Uma das formas de controlar o estoque é através de métodos como o ponto ideal de pedido, que busca identificar a relação do estoque mínimo do produto com o lead time de compra. Este conceito é essencial para garantir que a empresa tenha sempre a quantidade certa de produtos disponíveis, evitando tanto a falta quanto o excesso de mercadorias. O presente trabalho analisou o armazém dos produtos e evidenciar o impacto de um controle de estoque adequado. Para isso, é necessário analisar detalhadamente o banco de dados do setor de vendas, identificando os produtos de maior rotatividade e os mais vendidos. Com essa análise, foi possível constatar que os produtos que mais geram receitas para a empresa estão classificados no grupo “ração”. Além disso, houve uma grande oscilação nas vendas desses produtos, reforçando a necessidade de um controle de estoque preciso e bem gerenciado. Adicionalmente, foram identificados os pontos de pedido para os principais produtos, mantendo assim um estoque seguro e viável para a empresa. Essa identificação permite que a empresa reponha os produtos no momento exato, minimizando os riscos de falta de estoque que podem comprometer as vendas e a satisfação do cliente. Um estoque bem gerenciado também auxilia na redução de custos operacionais, evitando o acúmulo desnecessário de produtos. Portanto, o controle eficiente do estoque assegura a disponibilidade dos produtos mais vendidos e otimiza os recursos da empresa, garantindo uma operação mais fluida e lucrativa. Através do uso de métodos adequados e da análise constante dos dados de vendas, as empresas de varejo podem melhorar significativamente sua gestão de estoque.
The Subjective Ought and the Accessibility of Moral Truths
Authors: Choo Frederick
Published: June 2024

Many philosophers think that descriptive uncertainty is relevant to what we subjectively ought to do. This leads to a further question: is what we subjectively ought to do sensitive to our moral uncertainty as well? Includers say yes—what we subjectively ought to do is sensitive to both descriptive uncertainty and moral uncertainty. Excluders say no—only descriptive uncertainty matters to what we subjectively ought to do (i.e., moral uncertainty is irrelevant). Excluders argue that common motivations for the subjective ought only give us reason to think that descriptive uncertainty matters. This paper focuses on one motivation: accessibility. Excluders argue that accessibility does not motivate the Includers’ view because moral truths are always accessible – unlike descriptive facts which are not always accessible. My goal is to defend the Includers’ view by arguing that moral truths are not always accessible in the relevant sense.

The content explains the intuitive and logical aspects of the stories in the Koran. Intuition is a source of knowledge based on belief and experience. This dimension is found in the story of the Qur'an in various forms, initially in nature and unseen. It cannot be measured, but ultimately, it becomes logical because it is based on the laws that apply in society and can be validated through modern scientific approaches. It is what is called logical Intuition. This intuitive, logical aspect is found in Qur'an stories, which are attached to the principal or supporting characters and the story's plot. It is not revealed in the storyline, characterization, and message. Different from what was crystallized by Sayyid Quthb. He is an interpreter and writer who is clever at using persuasive narratives to arouse mental awareness and is straightforward so that it can be accepted by reason because it is by the realities of life and the laws that apply and develop in society. Perspective This is used as an approach to show the intuitive and logical aspects of the stories in the Qur'an.

Authors: Shalaby Mostafa , Saifan Hamed , Sooud Khaled , Tony Mohamed , Yassin Aya
Published: June 2024

Background:
Feed additives are products used in poultry nutrition to improve the quality of feed and safety of food byproducts from animal origin. They are promising antibiotic alternatives for production of broilers.
Aim:
This study aimed to investigate the effect of sodium butyrate (SB) and rosemary leaves (RL) on growth performance, biochemical profile, immunity, and carcass traits of broilers.
Methods:
Five hundred-one-day old chicks of Hubbard breed were reared on floor pens in a privet farm, Giza. The chicks were weighed on arrival (each chick weighted 43-45 gm) and randomly assigned into five equal groups, with four replicates each (25 chicks/replicate). Group 1 was fed on a broiler diet without any additions (control). The diets of groups 2 and 3 were supplemented with 500 g/ton SB and 4 kg/ton RL, respectively. In group 4, the diet was enriched with 250g/ton SB plus 2 kg/ton RL. Chicks in group 5 were fed on diet fortified with 500 g/ton SB plus 4 kg/ton RL.
Results:
Supplementation of broiler diet with 500 g/ton SB plus 4 kg /ton RL increased Body weight gain (BWG) and feed efficiency ratio (FER) of birds. It decreased serum levels of aspartate aminotransferase, alanine aminotransferase, total cholesterol triglycerides, malondialdehyde, but increased superoxide dismutase, catalase, and immunoglobulins, phagocytic activity, lysozyme activity, and nitric oxide concentrations. Antibody titers against Newcastle disease virus were also elevated.
Conclusion:
Supplementation of broiler diet with 500 g/ton SB plus 4 kg/ton RL gives the best result regarding productive efficiency and immunity of broiler chickens.
Anti-tumor effects of lapatinib on HER2-positive canine prostatic carcinoma cell lines
Authors: Kaji Kenjiro , Yonezawa Tomohiro , Yonezawa Tomohiro , Momoi Yasuyuki , Maeda Shingo
Published: June 2024

Background:
Canine prostatic carcinoma (cPC) is a urogenital tumor with poor prognosis, for which no effective treatment has been established. Recently, it has been shown that human epidermal growth factor receptor type 2 (HER2) is overexpressed in cPC cells; however, the efficacy of HER2-targeted therapy remains unclear.
Aim:
Investigate the anti-tumor effect of lapatinib on HER2-positive cPC cell lines.
Methods:
Two cell lines (muPC and bePC) were established from two dogs with cPC and the effects of lapatinib treatment on cell proliferation, apoptosis, and HER2 downstream signaling were investigated. Furthermore, muPC was used to generate tumor-bearing mice, and the anti-tumor effects of lapatinib were examined in vivo.
Results:
Lapatinib treatment inhibited the proliferation and phosphorylation of Erk1/2 and Akt, which are downstream signals of HER2. Furthermore, the TUNEL assay showed that lapatinib induced apoptosis in both cell lines. The muPC-engrafted nude mouse model showed that lapatinib significantly inhibited tumor growth and increased the area of necrotic tumor tissue compared to the vehicle-treated groups.
Conclusion:
Lapatinib exerts anti-tumor effects on cPC cells by inhibiting HER-2 signaling.
Erythropoietin as promoter of engraftment for treatment of radius/ulnar non-union fracture in a dog: Case report
Authors: Garnoeva Radka , Roydev Rumen , Vasileva Radina
Published: June 2024

Background:
Fractures with large bone defects and non-unions are a great challenge for veterinary orthopaedists. In small dog breeds, this complication is commonly encountered in fractures of the radius and ulna due to poorer vascularisation of the distal antebrachium region.
Case Description:
A case of radius/ulnar non-union in a 1.5-year-old Pinscher occurring after trauma and two successive unsuccessful osteosyntheses is described. During the operative revision, after removal of existing bone implants, the bone defect was filled with cortical autologous bone graft. Autocancellous bone mixed with erythropoietin was applied proximally and distally to the cortical autograft for stimulation of bone healing. The post-operative period was without complications. As early as the 9th post-operative week, the animal was able to bear weight on the limb, without signs of lameness, pain and swelling. Radiologically, a very good bridging of the graft was observed. Fifteen weeks after the operative revision, the fracture was completely healed with excellent clinical outcome.
Conclusion:
The application of autogenous cortical bone graft and cancellous autograft mixed with erythropoietin demonstrated an excellent therapeutic effect and resulted in complete regeneration of the large bone defect over a 15-week period.

Ces vidéos consistent en une longue succession d’images fixes issues d’un même processus de travail : des prises de vue des espaces sont combinées à des représentations des personnes réalisées en studio de manière à donner l’impression qu’un seul et même instant de la scène a été photographié selon une multitude de points de vue et de cadrages. Les deux vidéos consistent en un lent et long défilement bouclé de ces images composites en noir et blanc. L’effet conjoint de mouvement et d’immobilité est accusé par une bande-son qui égraine quelques notes de piano ou de guitare. Il s’agira de définir ce que recouvre l’expression « Sections of a Happy Moment ». On considérera que la représentation du bonheur dont il est question est tributaire des différents registres d’images auxquels ces œuvres se réfèrent, celui de la photographie de famille et celui des dispositifs de surveillance. Il conviendra également de prendre en compte le contexte architectural où ces scènes sont supposées avoir lieu ainsi que ceux et celles qui y vivent. C’est enfin de rythme des vidéos qui sera analysé en montrant qu’il permet d’établir une durée en phase avec le régime temporel qu’on associe au bonheur.
Architecture, Bonheur et banalité

Depuis plus d’un demi-siècle, la maison individuelle et son jardin restent le modèle d’habitation préféré des français. Les images publicitaires des constructeurs de pavillons, feignant la réalité de la parcelle et sa maison par l’utilisation d’imagerie 3D et de collages, permettent de saisir l’engouement toujours aussi fort que ce modèle suscite. En effet, elles offrent une collection dense et représentative de ce que l’on peut nommer le « rêve pavillonnaire ». Cet idéal se construit en images autour de systématismes de représentations qui délimitent les contours nets d’une certaine vision du bonheur, dont le pavillon est à la fois le décor et le moyen d’accès. Chaque image répète le même scénario : au premier plan, un jardin fleuri et maîtrisé, puis la maison détachée de son fond bleu, une voiture, un chien, une famille. À travers ces stéréotypes de représentation, qu’il s’agisse de composition spatiale, de personnages, de scènes ou d’objets, les publicités mettent en lumière les aspirations humaines profondes liées à l’habitat individuel. Au fil de cette imagerie répétitive et figée, le pavillon se présente comme la typologie d’habitation permettant au mieux l’expression du modèle traditionnel de la famille. D’une part, il offre une relation idéale avec ce dont il isole (la ville, le travail, les voisins, le reste du monde), et d’autre part, il permet l’attribution normée des rôles complémentaires incarnés par les différents membres de la famille. Dans son fonctionnement comme dans sa forme, le pavillon offre un modèle stable et familier qui rassure. Ainsi, il défend, à travers la sincérité de ses lignes simples et nettes, les valeurs d’honnêteté et d’innocence qui s’imposent inévitablement à ses habitants et leur mode de vie.La centaine d’images collectées offre une histoire universelle de la vie de famille dont on connaît par avance, et pour notre plus grand plaisir, le début, la fin et la trajectoire.
La photo 😀 toute seule

Depuis environ un siècle, les gens sourient sur les photos. Avant ce n’était pas le cas. Pour être plus sûres encore du résultat, des applications améliorent aujourd’hui nos sourires, si elles ne les créent pas de toute pièce. Elles suppriment nos imperfections, nous déplacent dans des décors de rêve, tandis que d’autres logiciels sélectionnent d’eux-mêmes les photos les plus réussies parmi les milliers que nous enregistrons, puis les diffusent accompagnées d’une jolie musique de fond.Bientôt, il ne sera plus nécessaire d’enregistrer des photos ou des vidéos : des logiciels dopés à l’intelligence artificielle produiront d’eux-mêmes les images idéalisées de notre bonheur.Nos photos personnelles et familiales ressemblent de plus en plus aux images de stock. Elles partagent leur style stéréotypé, clair, net, ordinaire, digeste, facilement compréhensible, et montrent le même monde idéalisé, heureux, souriant et lisse.Pour être plus sûres encore du résultat, des injections de Botox retendent nos visages, quelques coups de scalpel remettent en forme nos imperfections, des prothèses augmentent le volume de nos seins ou de nos fesses, des séances de sport en salle gonflent nos muscles, afin de faire coïncider notre physique et nos expressions avec les modèles de représentation.Bien que le concept de bonheur soit de nature flottante, éphémère et non quantifiable, il est aujourd’hui le sujet d’une injonction permanente. S’il est trop difficile de l’atteindre, différentes technologies du bonheur obligatoire produisent un arrière-plan qui s’ajoute automatiquement à nos existences et les reformatent pour s’approcher de la version idéalisée des images de stock et de la musique d’ambiance.C’est la vie sur fond vert.Ce texte s’intéresse aux divers procédés contribuant à rendre concrète et matérielle la pensée positive. Les modes de fabrication du sourire peuvent être directs et injonctifs (« Say cheese! »), médicaux (la chirurgie esthétique, qui solidifie littéralement le sourire sur le visage), simulationnels (intelligence artificielle), ou les trois simultanément.
Révolution française et fabrication de l’infamie politique
Authors: Soulas Nicolas
Published: June 2024

L’objectif de cette étude de cas centrée sur la chute des frères Payan, de la Drôme, est de mieux comprendre les mécanismes de construction et de déconstruction du héros révolutionnaire, et, partant, de l’infamie politique. En croisant les sources et les échelles du politique, il s’agira d’analyser les stratégies déployées par les « Thermidoriens » ou par les acteurs locaux pour abattre ces « idoles robespierristes ».
La légende noire de l’impératrice Eugénie : une damnation misogyne
Authors: Michelet Maxime
Published: June 2024

Eugénie de Montijo a été accusée de tous les maux : passionaria supposée de l’autoritarisme, responsable désignée des errements diplomatiques, hôtesse des décadences de la cour. Les fondements de cette légende noire sont à rechercher du côté d’une solide misogynie, réponse outrée aux responsabilités institutionnelles conférées par l’Empereur à son épouse. Eugénie fut en effet la femme la mieux préparée de son siècle à exercer la charge de l’État. Associée par son époux au conseil des ministres, désignée régente par l’Empereur, elle exercera trois fois la Régence et demeure la dernière femme à avoir occupé les fonctions de chef d’État en France. Restaurer l’Impératrice dans la réalité de son rôle politique et institutionnel fait apparaître encore plus nettement les bases de sa damnatio memoriae : l’effroyable transgression d’une « femme en politique » ne pouvait la condamner – à sa chute – qu’à la plus radicale des infamies.
Adelita, Valentina et les autres : la représentation des femmes révolutionnaires mexicaines dans les fictions narratives et filmiques du Mexique
Authors: Tachet Marie-Pierre
Published: June 2024

Bien que les femmes aient joué un rôle majeur dans la Révolution mexicaine, elles ont peu trouvé place dans les œuvres célébrant cette période. L’article montre la diversité des rôles qu’elles ont joués, de l’arrière, où elles ont assuré le ravitaillement, le blanchissage et les soins aux troupes, jusqu’à la pointe des combats, puisque plusieurs d’entre elles ont livré l’assaut. À ces cantinières et ces combattantes se sont ajoutées des espionnes, des journalistes, des infirmières allant jusqu’à fonder une nouvelle organisation de santé (la Croix blanche), des militantes plaidant pour une revalorisation des femmes dans le champ politique et social – autant de tâches essentielles que les représentations ultérieures ont occultées, cantonnant ces protagonistes dans le champ de la relation amoureuse, qui se prête idéalement à renforcer les hiérarchies genrées. L’article examine les différentes stratégies par lesquelles les représentations (lyriques, romanesques ou cinématographiques) ont neutralisé ces figures encombrantes, confirmant que les mouvements révolutionnaires ne sont pas nécessairement prêts à révolutionner le genre, et que l’intrusion du féminin en politique (en dehors de l’allégorie) a vite fait d’apparaître comme monstrueuse.

A lightwheel has the potential to be widely used to enhance the safety of racing cars and improve car performance by providing an estimation of wheel width spokes quantity, and other constant variables. This study is, therefore, aimed at designing a new lightweight racing wheel. In this study, a Finite Element Model (FEA) was implemented to investigate the static analysis of the newly designed lightweight racing wheel. Since the lightweight wheel characteristics play an important role in the stability and control of the racing car under severe manoeuvres, the wheel mass, von Mises stress, deformation, and safety factor were determined. It was observed that the circumferential component is vital for estimating the lightweight design of racing car wheel design. Therefore, this parameter could be better assessed for future studies.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from August 2020-June, 2021 to assess the allelopathic effects of the Echinochloa crusgalli residues on both rice yields and weeds therein. The experiment consisted five treatments of doses of residues of E. crusgalli viz. i) no residues (control), ii) E. crusgalli residues @ 0.7 t ha-1, iii) E. crusgalli residues @ 1.4 t ha-1, iv) E. crusgalli residues @ 2.1 t ha-1, v) farmers practice (two hand weeding @ 15 and 30 days after transplanting); and three treatments of the time of the application of the residues of E. crusgalli viz. i) one week before transplanting, ii) at the time of transplanting, iii) one week after transplanting. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Five weeds belonging to the five families were identified in the field such as Echinochloa crusgalli, Marsilea quadriflia, Monochori vaginalis, Paspalum scrobiculatum and Fimbristylis miliacea. The doses of residues of E. crusgalli had significant effect on yield and yield contributing characters of rice except number of non-effective tillers hill-1 and grains panicle-1. The highest grain yield (5.13 t ha-1), straw yield (6.19 t ha-1) biological yield (11.32 t ha-1) and harvest index (45.18%) were recorded when residues applied @ 2.1 t ha-1. In case of time of application of the residues, the highest grain yield (3.84 t ha-1) and straw yield (5.21 t ha-1) were found when the residues applied one week before transplanting. In case interaction between doses and time of application of the residues of E. crusgalli the highest the grain yield (5.98 tha-1), straw yield (6.67 t ha-1) and biological yield (11.32 t ha-1) were found when residues applied @ 2.1 tha-1 at one week before transplanting. Results of the study shows that the residues of Echinochloa crusgalli possess weed suppressing ability. Therefore, Echinochloa crusgalli residues could be applied to the rice field before one week of transplanting of seedlings to control weed growth and to get higher rice production.
