Authors: Silva Angélica da Fontoura Garcia , Campeão Vagner
Published: December 2024

Este estudo investiga os conhecimentos e as reflexões de professoras e futuras professoras sobre o ensino da divisão, com foco nos significados de partilha e cota. A pesquisa, conduzida em um grupo de estudos em uma escola pública de São Paulo, utiliza uma abordagem qualitativa para explorar os conceitos matemáticos associados à divisão. Os dados revelam que, dos 28 problemas elaborados pelas participantes, 24 abordaram a partilha, enquanto apenas 2 enfocaram a cota. As discussões evidenciaram que a partilha é mais familiar e concreta para as professoras, enquanto a cota apresentou maior grau de dificuldade. As participantes destacaram a importância de integrar ambos os significados no ensino da divisão, em conformidade com as orientações da Base Nacional Comum Curricular (BNCC), e discutiram estratégias para superar as dificuldades associadas ao significado de cota em sala de aula. A troca de experiências no grupo de estudos favoreceu a ressignificação dos conhecimentos e o aprimoramento das práticas pedagógicas. O estudo conclui que esses espaços de colaboração são fundamentais para o desenvolvimento do conhecimento profissional docente, permitindo que professoras ampliem suas estratégias de ensino e promovam uma abordagem mais equilibrada entre partilha e cota no ensino da matemática.

Effects of soil properties on erosion and breaching of natural coastal barriers under extreme storm surges
Authors: Elsayed Saber , Oumeraci Hocine , Goseberg Nils
Published: December 2024

Natural coastal barriers (NCB), e.g., barrier islands and dunes, represent important defense features against storm surges and coastal flooding. Due to climate change, the probability of extreme storms has been increased. Consequently, NCB may suffer significant erosion, which increases their breaching probability. However, available numerical models for NCB breaching still predict locations and sizes of possible breaches with moderate accuracy. This observation highlights the need for a deeper understanding of the factors triggering the alongshore variable response of NCB to storm surges so that weak locations can be determined. This exploratory study offers a synthesis of evidence that alongshore varying soil permeability of unvegetated NCB may control the alongshore varying abiotic soil resistance to erosion and determine possible breaching locations. Following research, therefore, presents an extension to the XBeach model, now accounting for spatial variability of soil resistance through soil permeability. To numerically quantify soil permeability effects on wave-induced breaching, the extended XBeach has been applied to a synthetic case study of spatially varying soil resistance. Results revealed that longshore variability of soil resistance along the barrier is mainly triggered by spatially varying permeability. The results also guide toward enhancing the resilience of NCB against breaching through improving their soil properties.
Reformulasi Norma Hukum Pasal 140 Ayat (2) Hurud D Kitab Undang-Undang Hukum Acara Pidana (KUHAP) Perspektif Due Process of Law
Authors: Jafril Muammar , Malik Faissal , Amriyanto
Published: December 2024

Masalah mendasar ketentuan Pasal 140 ayat 2 huruf (d) terletak pada belum diaturnya ketentuan mengenai limit waktu penentuan kembali sehingga kapan pun perkara dibuka maka mereka harus siap menyandang kembali status sebagai tersangka. Adapun tujuan dari penelitian ini ialah untuk menganalisis penuntutan kembali perkara pidana tanpa batas waktu sesuai asas due process of law dan norma pasal 140 ayat (2) huruf d KUHAP. Penelitian ini menggunakan metode hukum normatif dengan menganalisis norma hukum positif dan menghubungkannya dengan praktik pelaksanaan. Fokus penelitian adalah pemahaman terhadap permasalahan normatif dalam ilmu hukum dogmatik, meliputi deskripsi norma hukum, perumusan norma hukum (peraturan perundang-undangan), dan implementasi norma hukum (praktik yudisial). Hasil penelitian menunjukkan bahwa penuntutan kembali perkara pidana tanpa batas waktu ketentuan Pasal 140 ayat (2) huruf d KUHAP tidak mencerminkan prinsip keadilan, karena dimensi hak asasi manusia dan prinsip proses hukum yang adil (due process of law) tidak terwakili dalam konstruksi pasal tersebut. Jika suatu pasal dalam KUHAP tidak mengatur dengan jelas dan tegas untuk membatasi wewenang penegak hukum akan berpotensi subkjetif dalam memberikan hukuman, sehingga perlu adanya reformulasi terhadap pasal tersebut agar keadilan dalam proses peradilan dapat terwujud.

Published: December 2024

Penelitian ini bertujuan untuk mengetahui norma-norma adat dan budaya di Solok mempengaruhi stigma terhadap perempuan perokok di Solok. Metode yang digunakan adalah pendekatan kualitatif deskriptif dengan menggunakan konsep stigma menurut Erving Goffman sebagai kerangka teoritis utama. Subjek penelitian adalah masyarakat Solok berusia 17-40 tahun, sedangkan objek penelitiannya adalah perempuan perokok. Teknik wawancara mendalam dilakukan terhadap sepuluh informan yang dipilih secara purposif di Solok, dengan menggunakan triangulasi sumber untuk memastikan keabsahan data. Hasil penelitian menunjukkan bahwa sebagian infroman memiliki pandangan negatif terhadap perempuan perokok. Mereka menganggap bahwa perilaku merokok pada perempuan dapat merusak citra serta reputasi perempuan sebagaimana perempuan dalam budaya matrilineal. Dari perspektif adat dan budaya Solok, stigma negatif ini muncul karena adanya pandangan tradisional (matrilineal) yang memengaruhi persepsi terhadap perempuan perokok sebagai orang yang tidak mematuhi norma norma yang berlaku dalam masyarakat. Implikasi dari temuan ini adalah perlunya pendekatan yang lebih sensitif dan inklusif dalam memahami faktor budaya lokal dalam mengelola stigma terhadap perempuan perokok di masyarakat Solok. Penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan strategi intervensi sosial yang lebih efektif untuk mengurangi stigma dan meningkatkan dukungan terhadap perempuan perokok.

Published: December 2024

Background: Acute pesticide poisoning has remained a significant public health concern for decades. Supportive care has been the mainstay of treatment. Intravenous lipid emulsion (ILE) therapy offers a potential new strategy.
Objectives: This systematic review aimed to evaluate the current research on the efficacy of ILE in treating aluminum phosphide (AlP) poisoning.
Methods: A comprehensive electronic search was conducted across various databases including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Campbell Systematic Reviews, Scopus, Web of Science, Springer Nature, Elsevier, Google Scholar, and regional databases encompassing Mansoura, Zagazig, Ain Shams universities, and Indian publications. Studies published in English language were considered for inclusion (from 2015 to 2023). Inclusion criteria focused on human studies evaluating the use of ILE for AlP intoxication.
Results: Five studies met the inclusion criteria, three studies were randomized controlled trials, one was observational cross sectional study, and one was case report encompassing a total of 224 patients. Of these, 102 patients received ILE, with all studies utilizing 20% ILE. Three studies administered ILE as a continuous intravenous infusion at a rate of 10 mL/h. Two other studies employed a bolus dose regimen, ranging from 1-3 mL/kg delivered over one minute, followed by continuous infusion. The overall mortality rate was 68.6% in the ILE group compared to 76.2% in the control group and the need for mechanical ventilation was lower in the ILE group with clinical improvement in the ILE group.
Conclusion: Intravenous lipid emulsion represents a novel therapeutic approach in toxicology with the potential to improve patient outcomes. This review suggests ILE may reduce mortality associated with AlP poisoning. Additionally, ILE use might be associated with decreased, need for mechanical ventilation, hospital stay and discharge time among survivors.

Authors: Gannamaneni Sriraj , P Anitha , AS Smiline Girija , Priyadharsini Vijayashree
Published: December 2024

Objective: Periodontitis is a chronic inflammatory disease affecting teeth' supporting tissues. It is caused by specific bacterial species, including Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), and Treponema denticola, known as the "red complex" group. These bacteria manipulate the immune response and promote tissue destruction, making them key players in periodontal pathogenesis. The present study aims to identify the potential molecular targets of Emodin against the red complex pathogens.
Method: The interaction between the phytocompound Emodin and red complex pathogens was identified using the STITCH tool. The proteins identified were then classified into functional categories using the VICMPred. The virulent proteins identified were then subjected to Bepired prediction, which provided information about the epitopes in the virulent proteins. Finally, the subcellular location of the proteins was demonstrated with the pSORTb tool.
Results: Carbamoyl-phosphate synthase is a large subunit identified as a virulence protein in Pg and Tf. DNA topoisomerase IV subunit A was found to be the common virulence protein for Pg and Td. The DNA gyrase subunit A and ATPase/histidine kinase/DNA gyrase B/HSP90 domain-containing protein were found to be identified in Td and Tf. It was the only protein predicted to be in the cytoplasmic membrane, while others were found in the cytoplasm. The four virulent proteins targeted by Emodin were found to harbor multiple epitopes.
Conclusion: Emodin was found to interact with all three pathogens of the red complex group. However, further experimental validation is warranted to prove the antimicrobial effect of Emodin against periodontal pathogens.

The preponderance of microbial and oxidative stress-mediated diseases is quite alarming. The need for novel drug development is highlighted by the fact that antimicrobial resistance is rising and many current antioxidant drugs only provide little symptomatic alleviation. The aim of this work was to synthesize leucine derived sulfamoyl pentanamides with antioxidant and antimicrobial activities. New leucine-based sulfamoyl pentanamides were synthesized and elemental analysis, 1H-NMR, 13C-NMR, and FTIR were used to elucidate their structures. They underwent molecular docking investigations as well as in vitro antioxidant and antimicrobial activity analyses. Compound 5a (0.60 gm/ml) was the most active compound against Pseudomonas aeroginosa, whereas compound 5f (0.30-0.40 mg/ml) was the most effective antibacterial agent against E. Coli, S. typhi, S. aureus, and B. subtilis. The compounds with the best antifungal activity against C. albican and A. niger, respectively, were 5g (0.80 mg/ml) and 5e (0.50 mg/ml). In the in vitro antioxidant assessment, compounds 5g (1.174µg/ml) and 5h (1.172µg/ml) exhibited similar antioxidant activity to ascorbic acid (IC50 1.001µglml). In addition, most of the target compounds have relatively strong antibacterial, antifungal, and antioxidant potentials, according to molecular docking study. Since every target compound complied with Lipinski's rule of five, it is likely that they might be used as therapeutic candidates to treat oxidative stress-related illnesses and microbial infections.

New design of the conic shape screw conveyor is presented in the paper and the results of theoretical investigations of the bulk material kinematic movement in this conveyor were shown. Dependencies for finding kinematic and operating parameters, which provide long-term stability of such mixers were found. Stand equipment for investigation of the transporting efficiency and mixing of the bulk materials have been developed and manufactured. Mechanic screw conveyors’ properties at high frequency range of rotation, under smooth and sharp starting, rotation frequency change and reversing in the automatic regime have been studied taking advantage of the ALTIVAR 71 and multipurpose measuring system with accelerometers for finding dynamic loadings by PC. The results of experimental investigations of the efficiency depending on the screw pitch and every next turn, the screw conic surface inclination and the screw rotation frequency are presented. It will make possible to clear the process of the bulk materials transporting and mixing for every possible combination of the initial parameters. Specifically, increasing the increment of the cargo displacement radius per turn from 1 mm to 5 mm results in a velocity increase ranging from 1.28 times to 2.44 times. Moreover, increasing the inclination angle of the forming cone surface from 1 degree to 2 degrees provides a 1.18-fold increase in productivity, and varying the increment of the screw pitch from 0.004 m to 0.01 m per turn results in a 1.07-fold decrease in productivity. Increasing the rotation frequency of the conical screw α from 200 r/min to 500 r/min leads to a doubling of productivity.

Authors: LI Zhibo , LIU Yuan
Published: December 2024

Multi-unmanned aerial vehicle (UAV) collaborative task planning and distribution path planning are the core content of agricultural UAV logistics distribution. In this study, the multi-UAV collaborative task planning and the distribution path planning were discussed, and such constraint conditions as UAV load capacity, battery capacity and flight time were comprehensively considered, aiming to reduce the number of UAVs and their power consumption. To ensure the safe and efficient completion of multi-UAV logistics distribution tasks, 3D agricultural ultralow space was subjected to environment modeling, and a bilevel planning model for collaborative planning of UAV distribution route and flight path was constructed. Then, an improved particle swarm optimization (PSO) algorithm with the improved learning factor and inertia coefficient was designed on the basis of PSO framework, and the global optimal solution in the current iteration was improved using variable neighborhood descent search. The feasibility of the proposed algorithm was verified by analyzing a practical case. With the central city area of XX City as the study area, 1 logistics & freight transportation center was taken as the central warehouse (coordinates: 50, 50, unit: km) and 50 intelligent express cabinets as the express cabinets of UAVs. The obtained results were comparatively analyzed with those acquired through the basic PSO algorithm. The results manifest that the proposed algorithm performs better than the compared algorithms. The improved PSO algorithm is superior to the basic PSO algorithm in aspects of total UAV flight distance, number of UAVs used and algorithm convergence time, indicating that the model and algorithm established in this study are feasible and effective.

Published: December 2024

In the context of the development of intelligent systems in the agricultural field, systems that help farmers in agricultural production, the realization of intelligent systems to help them in the commercialization of agricultural products is both actual and necessary. The commercialization of agricultural products directly by the farmer, at the farm gate, requires specially authorized spaces, personnel, connection to utilities, etc., which limits the possibilities for sale of products by farmers, thus losing both the final customer and the farmer, as the product enters the distribution chain, which implies an additional cost and uncertainties regarding the product origin. The article presents the SVIEE-R equipment, an automatic and autonomous system for selling agricultural products at the farm gate, which does not require the presence of a salesperson or connection to electricity and which can store agricultural products that require refrigeration, such as: vegetables, fruits, dairy products, etc. The intelligent SVIEE-R vending machine is a smart system that continuously informs both the farmer and the customer about the stock level of stored products, the storage temperature, and can be placed anywhere due to the energy independence provided by an array of photovoltaic panels and accumulators.
OBSTACLE AVOIDANCE PLANNING OF GRAPE PICKING ROBOTS BASED ON DEEP REINFORCEMENT LEARNING
Authors: LIU Pei
Published: December 2024

Given that picking robots are faced with many picking tasks in the field operation environment and the target and obstacles are located at random and uncertain positions, an obstacle avoidance planning method for the picking path of virtual robots based on deep reinforcement learning was proposed to achieve rapid route planning of robots under a lot of uncertain tasks. Next, the random motion strategy of virtual robots was set according to the physical structure of robot bodies. By comparatively analyzing the advantages and disadvantages of the observed values input by different networks, an environmental observation set was established in combination with actual picking behaviors as the network input; then, a reward function was established by introducing the idea of target attraction and obstacle repulsion contained in the artificial potential field method, aiming to evaluate the behavior of virtual robots and increase the success rate of obstacle avoidance. The results of the simulation experiment showed that the success rate obtained by virtual robots in completing the picking task reached 95.5% under obstacles set at different positions. The coverage path length of the deep reinforcement learning algorithm was reduced by 272.79 in compared with that of genetic algorithm, with a reduction rate of 5.09%. The total time consumed by navigation was 1549.24 s, which was 83.15 s shorter than that of the traditional algorithm. The study results manifest that the system can efficiently guide virtual robots to rapidly reach the random picking points on the premise of avoiding obstacles, meet picking task requirements and provide theoretical and technical support for the picking path planning of real robots.

The research aims to estimate the influence of the main vibration sources in grain harvesters on the combine operator. The study also has a comparative aspect, including two harvesters, a conventional one (C 110H) and one with an axial flow (CASE IH). The main sources of vibration considered were the thresher, chassis, and header for both types of harvesters, with the addition of the shaker as a source for the conventional harvester. The receiver is considered to be the operator's seat. The emission spectra of each source are recorded according to ISO 2631-1:2001 and ISO 2631-5:2018, as well as the spectrum received at the operator's seat. To estimate the influence of vibration sources on the operator's seat, interspectral correlations and influence coefficients were studied. The conclusions are useful for ranking the intensity of vibration sources affecting the operator's comfort and for comparing the comfort level between two grain harvesters with different operational technologies. What the paper introduces as new in the field of estimating the exposure time limit to harvester vibrations is the calculation algorithm for the exposure time limit and vibration intensity estimators.

In order to prolong the preservation period of daylily and make better use of its edible value, most of the daylily on the market are dried vegetables. Aiming at the problems of small size of dried daylily, similar color and texture between dried daylily, and difficulty in grading, this study proposes a method for grading dried daylily based on SSD. In the backbone feature extraction stage, the original backbone network VGG16 is replaced with the residual network model ResNet50 to realize the feature extraction of dried daylily. ResNet50 can deepen the network better and is more suitable for dried daylily feature extraction. Secondly, a feature fusion layer is added to improve the problem of insufficient utilization of shallow features in SSD network, which is more suitable for detail detection and improves the accuracy of dried daylily grading. Finally, the input image size is selected [512,512] to increase the image pixels, so that the network can capture more details of the dried daylily to improve the detection accuracy. The results show that the grading precision of the improved SSD algorithm is significantly improved compared with the traditional SSD, and the mean average precision is increased by 4.17%. At the same time, the same data set was used to test on the YOLOv5 model. Compared with YOLOv5s, YOLOv5s-CA and YOLOv5s-CBAM, the mean average precision was increased by 18.32%, 21.82% and 22.02% respectively, which further verified the precision and feasibility of the method and provided effective technical support for the grading of dried daylily.
