Introduction

In the global field of nanotechnology, the production of silver nanoparticles (AgNPs) is an environmentally beneficial technique. To prevent the diseases caused by many commonly used pesticides, it is essential to synthesize safe alternatives from low-cost sources.

Material and methods

This study focuses on the eco-friendly extracellular production of AgNPs using an aqueous extract of Ulva lactuca as a reducing agent in a silver nitrate solution. The biosynthetic reaction was confirmed through various analytical techniques, including ultraviolet–visible (UV–Vis) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), and energy dispersive X-ray analysis (EDAX). Moreover, antioxidant activity was confirmed. It has also been evaluated against a variety of bacteria and fungi that have an impact on humans, animals, and plants.

Results and discussion

The mean size of the nanoparticles (NPs) varied from 45–61 nm. The disk diffusion testing results show that, in comparison to the tested antibiotics, Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, and Klebsiella pneumoniae were more responsive to U. lactuca-silver nanoparticles (U-AgNPs) extract. eldor 50% sc fungicide was used at the prescribed dose of 0.5 μL/mL, and the antifungal activity of aqueous and U-AgNPs extracts was examined at three concentrations of 0.62, 1.25, and 2.5 mg/mL. Through the suppression of spore germination, in vitro investigations demonstrated that U-AgNPs at varying doses greatly hindered the process of reproductive growth of Botrytis cinerea. Comparing U-AgNPs to the standard synthetic fungicide Teldor 50% sc, it is noteworthy to observe that a substantial control efficacy against tomato and strawberry gray mold was noticed, especially at concentrations of 2.5mg/mL on the entire tomato and strawberry plants and also on the detached leaves and fruits without causing any appearance damage. In summary, this study advances the field of agronanotechnology by demonstrating the potential application of a fungicide based on NPs to prevent gray mold on tomato and strawberry plants in greenhouse environments and throughout the postharvest phase.
Surgeons’ opinions and concerns regarding prophylactic mesh placement when conducting a permanent ileo- and colostomy A survey among 172 surgeons in Germany, Switzerland, and Austria
Authors: Paasch Christoph , Kalmykov Egan Leonidovich , Lorenz Ralph , Neveling Nele , Mantke Rene
Published: November 2024

Background

Prophylactic mesh placement when creating a permanent colostomy was recommended by the 2017 European Hernia Society guidelines on the prevention and treatment of parastomal hernias (GPTPH2017). The extent of this recommendation is under debate based on the long-term data from clinical trials. Our aim was to conduct a survey of surgeons revealing perspectives and concerns regarding GPTPH2017 and to discuss their concerns.

Methods

From January 2023 to September 2023 a survey among surgeons of Germany, Switzerland and Austria was conducted. The questionnaire addressed demographic data of the participants, information on work experience/location, number of elective permanent colo- and ileostomies, and opinions on the recommendation of GPTPH2017 for prophylactic mesh placement.

Results

A total of 172 surgeons from Germany, Austria and Switzerland answered the questionnaire and 59 of them stated professional experience of 20–30 years. Most of the surgeons (n = 51, 31.3%) worked in a primary care hospital. A total of 112 participants were familiar with the GPTPH2017. Sixty-five surgeons (40%) stated that they never conduct a prophylactic mesh placement when creating an elective permanent colostomy (rarely, n = 44 (26.7%). Seven participants always place a mesh (4.2%, missing data: 7). Main concerns regarding prophylactic mesh placement was the concern of surgeons about wound infection (n = 107, 67.7%) and lack of evidence (n = 65, 41.1%). For some participants the GPTPH2017 is seen to be industry-driven with low evidence, too old and leading to overtreatment.

Conclusions

The main reason for not placing a prophylactic mesh when conducting a permanent colostomy was the risk of wound infection.
The Role and Mechanism of Deubiquitinase USP7 in Tumor-Associated Inflammation
Authors: Wang Luhong , Zhang Yong , Yu Tao , Wu Huijian
Published: November 2024

Deubiquitinating enzymes are a class of proteases that remove ubiquitin tags from proteins, thereby controlling protein stability and function. Tumor inflammation arises from interactions between tumor cells and their microenvironment, which trigger an inflammatory response. The deubiquitinating enzyme USP7 plays a central role in this process. Research suggests that USP7 may modulate various signaling pathways related to inflammatory responses through its deubiquitinating activity, thereby influencing tumor development and progression, including regulating T cell immune activity, improving macrophage anti-tumor activity, and regulating NF-κB signal pathways. Overall, describing the role and mechanism of USP7 in the tumor inflammatory response is of great importance for elucidating the regulatory mechanism of tumor inflammation and developing new therapeutic strategies. This article mainly reviews the structure, function, role, and mechanism of USP7 in the tumor inflammation response.
Complexity Quantification of Driving Scenarios with Dynamic Evolution Characteristics
Authors: Liu Tianyue , Wang Cong , Yin Ziqiao , Mi Zhilong , Xiong Xiya , Guo Binghui
Published: November 2024

Complexity is a key measure of driving scenario significance for scenario-based autonomous driving tests. However, current methods for quantifying scenario complexity primarily focus on static scenes rather than dynamic scenarios and fail to represent the dynamic evolution of scenarios. Autonomous vehicle performance may vary significantly across scenarios with different dynamic changes. This paper proposes the Dynamic Scenario Complexity Quantification (DSCQ) method for autonomous driving, which integrates the effects of the environment, road conditions, and dynamic entities in traffic on complexity. Additionally, it introduces Dynamic Effect Entropy to measure uncertainty arising from scenario evolution. Using the real-world DENSE dataset, we demonstrate that the proposed method more accurately quantifies real scenario complexity with dynamic evolution. Although certain scenes may appear less complex, their significant dynamic changes over time are captured by our proposed method but overlooked by conventional approaches. The correlation between scenario complexity and object detection algorithm performance further proves the effectiveness of the method. DSCQ quantifies driving scenario complexity across both spatial and temporal scales, filling the gap of existing methods that only consider spatial complexity. This approach shows the potential to enhance AV safety testing efficiency in varied and evolving scenarios.
Balancing Page Endurance Variation Between Layers to Extend 3D NAND Flash Memory Lifetime
Authors: Wang Jialin , Fan Yi , Du Yajuan , Huang Siyi , Wan Yu
Published: November 2024

With vertical stacking, 3D NAND’s flash memory can achieve continuous capacity growth. However, the endurance variation between the stacked layers becomes more and more significant due to process variation, which will lead to the underutilization of many pages and seriously affect the lifetime of 3D NAND’s flash memory. We investigated the endurance variation characteristics between layers and divided the stacked layers into the top, middle, and bottom layers according to the endurance characteristics. We found that the endurance of the bottom layer pages is much weaker than that of the other two layers, which is the primary factor that affects the lifetime of 3D NAND’s flash memory. In response to this endurance variation feature, we proposed a new layer-aware write strategy, called LA-Write. First of all, the write–skip unit in LA-Write will reduce the wear pressure of the pages through write–skip operations. Secondly, LA-Write maintains a layer-aware table, which stores the probability of pages in different layers performing the write–skip operation. Setting the probability of the bottom pages to the highest value will result in more write–skip operations on the bottom layers, mitigating endurance variations between layers. We carried out our experiments of LA-Write on DiskSim, a popular SSD simulator. Compared to existing schemes, experimental results show that LA-Write can greatly increase SSD’s lifetime.

Authors: Shao Junli , Wu Di
Published: November 2024

In response to the issues of dye wastewater pollution and coal gangue accumulation, a novel adsorbent, coal gangue-loaded hydroxyapatite (CG@HAP) was prepared using coal gangue as the raw material for the adsorption of malachite green dye wastewater. Based on batch experiments, combined with adsorption kinetics and isotherm models, as well as XRF, FTIR, XRD, and SEM analysis, the characteristics of CG@HAP in adsorbing malachite green were investigated. The results show that CG@HAP can be prepared by adding 150 mL of 0.15 mol/L (NH4)2HPO4 solution and 150 mL of 0.25 mol/L CaCl2 solution to 10 g coal gangue under the condition of pH = 10, allowing it to stand at room temperature for 24 h. When the dosage of CG@HAP was 0.10 g and the adsorption time was 180 min, the adsorption removal rate and adsorption capacity of CG@HAP for 400 mg/L malachite green reached 92.62% and 370.49 mg/g, respectively. The adsorption of malachite green by CG@HAP followed the pseudo-second-order kinetic model and the Langmuir isotherm model. The adsorption of malachite green by CG@HAP was primarily governed by chemical reactions, adhering to the Langmuir monolayer adsorption principle. The maximum adsorption capacity of CG@HAP for malachite green was 386 mg/g. CG@HAP exhibited sustained and efficient dynamic adsorption of malachite green, maintaining a removal rate between 83.52% and 99.96%. CG@HAP proved to be an efficient adsorbent for malachite green, with great potential for application.

Agunmu (ground herbal medicine) is a form of West African traditional medicine consisting of a cocktail of herbs. The goal of this study is to evaluate a formulation of Agunmu made from M. indica, A. repens, E. chlorantha, A. boonei, and B. ferruginea, sold in the open market and commonly used for the treatment of malaria by the locals, for its antimalarial effects and to determine the active principles that may contribute to the antimalarial effect. The ethanolic extract obtained from this formulation (Ag-Iba) was analyzed, using TLC, LC-MS, and Tandem-MS techniques, to determine its phytochemical properties. The extract was tested in vitro against representative bacteria strains, cancer and normal human cell lines, and susceptible (D6) and resistant (W2) Plasmodium falciparum. In subsequent in vivo experiments, graded doses of the extract were used to treat mice infected with chloroquine-susceptible (NK-65) and chloroquine-resistant (ANKA) strains of Plasmodium berghei. Bacteria growth was monitored with a disc diffusion assay, cancer cell viability was determined with MTS assay, and percentage parasitemia and parasite clearance were determined by microscopy. Bound heme content, host mitochondria permeability transition (mPT) pore opening, F0F1-ATPase, and lipid peroxidation were determined via spectrophotometry. Indices of oxidative stress, anti-oxidant activities, toxicity, cell death, and inflammatory responses were obtained using biochemical and ELISA techniques. The histology of the liver and spleen was performed using the standard method. We elucidated the structures of the critical active principles in the extract to be flavonoids: kaempferol, quercetin, myricetin, and their glycosides with little or no detectable levels of the toxic Aristolochic acids that are found in Aristolochia repens, one of the components of the formulation. The extract also showed anti-plasmodial activity in in vitro and in vivo models. Furthermore, the extract dose-dependently decreased mitochondrial dysfunction, cell death, and inflammatory and oxidative damage but increased antioxidant potentials. Presumably, the active principles in the extract work as a combinatorial therapy to elicit potent antimalarial activity. Overall, our study unraveled the active components from a commercial herbal formulation that could be reformulated for antimalarial therapy.
Decision-Making in Remanufacturing Supply Chains: Game Theory Analysis of Recycling Models and Consumer Value Perception
Authors: Cheng Yingchun , Wang Jianhua
Published: November 2024

In view of the uncertainty regarding consumers’ perceived value of remanufactured products, a remanufacturing supply chain system with the manufacturer as the Stackelberg leader is constructed, in which the manufacturer faces three modes, namely the manufacturer recycling mode (M), the retailer recycling mode (R), and the entrusted third-party recycling mode (3P). The remanufacturing supply chain is analyzed using the game theory approach in these three recycling modes. Using game theory to analyze the optimal pricing and profits of each supply chain participant, we also discuss the impact of consumers’ perceived value uncertainty on the profits of each party under the different recycling modes, and we then explore the selection of recycling channels in the remanufacturing supply chain. The results show that when the perceived value uncertainty is at a medium or low level, retailers are responsible for recycling used products and producing remanufactured products, which brings higher profits to the supply chain system; when the perceived value uncertainty is high, the demand for remanufactured products in the market decreases, and the recycling revenue of remanufactured products is lower. Finally, the validity of the theoretical model is verified by a numerical simulation.

Authors: Altınok Yipel Fulya , Yipel Mustafa , Altuğ Nuri , Özdemir Nurullah
Published: November 2024

Depending on bioconcentration, elements are classified as macro and micro. While some are essential for biological processes but may be toxic above the tolerable concentrations, than is necessary to monitor the concentrations. Also, the deficiency or excess of micro- and macroelements may diminish the effect of substances, such as other elements or drugs, or cause them to exert toxic effects. In the present study, macro (Ca, K, Mg, Na, and P) and micro (Al, B, Mn, Mo, Sb, Sn, and Tl) element concentrations and correlations were determined in shelter dogs. According to the results, the high to low micro- and macroelement concentrations were found to be K>Ca>P>Mg>Na and Se>Al>Mn>B>Mo>Sb>Sn>Tl respectively. Statistically significant positive (Ca-Sn, Mg-Mn, Mg-Sb, Mg-Se, P-Al, P-Sb) and negative (K-Al, K-Mn, Na-Al, Na-Sb, Na-Sn) correlations were determined between macro- and microelements. The concentrations of the macroelements that were analyzed in this study were within the reference range. There is no data on the concentrations and biological or toxic effects of some elements, such as B, Sb, Sn, and Tl, in dogs. Reference biomarkers should be identified for the early diagnosis of conditions induced by altered element concentrations and the health impacts of these changes should be thoroughly investigated.

Published: November 2024

In this study, the finite element method is used to analyse the distribution of shear stresses in aeronautical structures repaired by composite patching and reinforced with a metallic stiffener. The stress distribution in the adhesive layer will be analysed to estimate the durability of the repair technique in the presence and absence of the stiffener in the aeronautical structure. The results obtained show that the presence of the stiffener does not have a significant effect on the level of adhesive stresses under the composite patch, but conversely the adhesive stresses under the stiffener are quite high. This study was carried out for the case of plates.

The present study addressed the cardiovascular complications arising from dengue virus (DENV) infection. Dengue is a disease transmitted by mosquitoes of the species Aedes aegypti. This disease can range from mild to severe, being classified into four categories: A (without warning signs), B (with warning signs), C (severe), and D (complicated). DENV infection can provoke an intense inflammatory response, increased vascular permeability, and direct damage to cardiomyocytes. This can lead to various cardiovascular complications, including myocarditis, pericarditis, and cardiomyopathies. The critical phase of dengue is marked by cardiovascular symptoms such as hypotension, cardiac rhythm disturbances, and signs of heart failure. Studies in animal models have shown that DENV infection results in systemic inflammation, increased vascular permeability, reduced blood pressure, and alterations in cardiac function. The association between preexisting cardiovascular diseases and severe dengue infection is complex, increasing the risk of severe complications. Dengue treatment is mainly symptomatic, involving hydration and the use of analgesics, with intensive support measures in severe cases. Early identification and adequate treatment of cardiovascular complications are essential to improve clinical outcomes. Therefore, it can be concluded that dengue represents a significant challenge to public health, especially in endemic regions. Understanding the cardiovascular complications associated with DENV infection is crucial for the effective management of patients and for reducing mortality. Continuous research and epidemiological surveillance are essential to improve dengue prevention and treatment strategies, ensuring a better quality of life for affected patients.

A Cefaleia é  comum nos serviços de saúde, afetando grande parte da população, e entender sua origem é fundamental para escolher o tratamento correto. Este estudo tem como objetivo avaliar a relação entre os possíveis tratamentos, a migrânea e o neuropeptídeo CGRP (Peptídeo relacionado ao gene da calcitonina). Para alcançar esse objetivo foram analisadas diversas referências sobre o tema, buscando relações e discrepâncias. A discussão deste estudo mostrou que novos tratamentos com monoclonais, conhecidos como "gepants", baseados no CGRP, são eficazes em reduzir tanto a frequência quanto a intensidade das crises de enxaqueca em pacientes difíceis de tratar. Entretanto, apesar de serem seguros, seu uso pode ser limitado devido à necessidade de administração intravenosa e custo elevado. Dessa forma, esses medicamentos estão se tornando opções de tratamento de destaque para casos severos de migrânea, embora sua aplicação dependa de considerações individuais e custo-benefício.

Published: November 2024

Digital skills form an integral part of the success of digital transformation in an internal audit function. The internal audit function has a responsibility to facilitate digitalization and automate procedures to verify that each phase relating to the mission is efficient and cost-effective. Factors that create an efficient internal audit process need to be detected in order to improve the digital transformation process.
A qualitative methodology parallel to the quantitative analysis discusses open-ended questions from questionnaires and interviews with BADR Bank auditors. In this way, the mixed-methods approach will produce a statistical perspective and granular insights from the auditors' point of view to enable a more subtle fine-tuning of the internal audit process for organizations working hard towards the automation of procedures.
The main objective of this article: to understand the new perspectives on smart ways to perform internal auditing using digital technologies.
Essay on the determinants of the location of industrial companies: case of the Akbou industrial zone
Authors: Siham Hamitouche , Ouidir Souman Mohand
Published: November 2024

The objective of our work is to study the factors influencing the location of industrial companies in the Taharacht (Akbou) area of Algeria. After a theoretical analysis of models and paradigms, our results revealed that the proximity of production factors does not influence the location of industrial companies in the Taharacht-Akbou area; instead, the presence of other industries, known as the "effect of externalities," guides their location. The analysis also reveals that the "industrial zone" serves as the primary and most important factor in determining the location of companies in this particular locality. The unique feature of the industrial zone lies in its ability to offer benefits such as reduced implementation costs and the availability of attractive land suitable for industrial buildings, among other benefits.

A região Nordeste do estado do Pará enfrenta um sério problema de degradação de pastagens devido à atividade pecuária. O sistema Integração Lavoura Pecuária Floresta (ILPF) surge como uma alternativa promissora para reverter esse cenário, combinando a recuperação ambiental com a viabilidade econômica. Esse trabalho tem como objetivo avaliar as modificações na fertilidade do solo após cinco anos de cultivo de espécies florestais no sistema ILPF, visando a recuperação de áreas de pastagens degradadas. Foram comparadas duas áreas: uma com cultivo de milho intercalado com as espécies florestais mogno africano e paricá (Khaya ivorensis e Schizolobium amazonicum), respectivamente, e outra com cultivo convencional de milho. Após cinco anos, foram coletadas amostras de solo em diferentes profundidades para analisar a fertilidade. Os resultados mostraram que os sistemas ILPF contribuíram para a recuperação da fertilidade superficial, reduzindo a erosão e aumentando o teor de matéria orgânica e alguns nutrientes. No entanto, observou-se redução da fertilidade em profundidade e aumento do alumínio. Esses resultados indicam a necessidade de se estabelecer um manejo adequado da fertilidade do solo para otimizar os benefícios do ILPF e garantir a sustentabilidade do sistema a longo prazo.

Authors: Şahin Emrullah , Arslan Naciye Nur , Aydemir Fırat
Published: November 2024

The Industrial Internet of Things (IIoT) refers to a structure where multiple devices and sensors communicate with each other over a network. As the number of internet-connected devices increases, so does the number of attacks on these devices. Therefore, it has become important to secure the data and prevent potential threats to the data in factories or workplaces. In this study, a deep learning-based architecture was used to determine whether the data collected from IIoT sensors was under attack by looking at network traffic. The data that was not exposed to attacks was stored on the Ethereum Blockchain network. The Ethereum blockchain network ensured that sensor data was stored securely without relying on any central authority and prevented data loss in case of any attack. Thanks to the communication process over the blockchain network, updating and sharing data was facilitated. The proposed deep learning-based intrusion detection system separated normal and anomaly data with 100% accuracy. The anomaly data were identified with an average of 95% accuracy for which attack type they belonged to. The data that was not exposed to attacks was processed on the blockchain network, and an alert system was implemented for the detected attack data. This study presents a method that companies can use to secure IIoT sensor data.

Authors: Melo Lourido Gilcélia , da Silva Figueiredo Adrya , Guzzo Coutinho Paulo Eduardo , Carvalho Raymê dos Santos , Sousa Cézar Kelve Franklimara
Published: November 2024

In this work, we report a rare feeding behavior, where adults of two species of frugivorous butterflies were feeding on fungi, Hamadryas februa februa (Hübner) on Auricularia cornea Ehrenb., and Pierella lena brasiliensis (Felder & Felder) on Phallus indusiatus Vent. These events occurred between April and May 2024 in two distinct areas: the first at Campus I of the Instituto Nacional de Pesquisas da Amazônia (INPA) and the second at the Museu da Amazônia (MUSA), both in Manaus, State
of Amazonas, Brazil. The rarity of mycophagy events involving Lepidoptera adults, as observed
twice here, suggests a potential for the dispersal of fungal spores and underscores the need for more studies to further explore the relationship between these taxonomic groups.

Minas Gerais state, Brazil, is home to significant biological diversity, including social wasps
(Vespidae: Polistinae). However, they have suffered substantial losses of their original cover due to anthropogenic actions, which justifies carrying out inventory studies. Therefore, this study aims to analyze the species richness and distribution of social wasps in Minas Gerais and add information
to the municipality of Luminárias, southern Minas Gerais. There are inventories in 32 locations
in Minas Gerais, inside and outside Conservation Units (CUs), with a higher concentration in the
Atlantic Forest. In total, 118 social wasp species are recorded in the state and 74 are considered rare, i.e. occurring in less than 20% of the localities. The Caatinga, along with the protected areas in the Cerrado and the Atlantic Forest in the eastern and northeastern parts of the state, is under-sampled. Luminárias, despite not being located in a UC, has a considerable richness of rare species, two of which have only been previously recorded in Conservation Units. This allows us to infer that this municipality is home to a relevant vespid fauna for the state, corroborating other studies that suggest the creation of a UC for the region

Este livro traz uma série de reflexões sobre a extrema violência da ocupação do território em seus diversos momentos, da Colônia ao Brasil do milagre econômico. Da província do Grão-Pará ao “vazio” da Amazônia e de Mato Grosso, ainda antes de sua divisão administrativa. Os artigos são fruto do VII Seminário Internacional História e Historiografia, evento que consolida uma rede de programas e pesquisadores, cuja articulação, iniciada em 2005, destaca discussões e histórias que durante muito tempo foram relegadas ao segundo plano, mas que são fundamentais para que possamos compreender nossa formação como povo, como nação.

Published: November 2024

Kehadiran imam dalam Gereja memiliki peran yang sangat penting. Peran utama seorang imam adalah menjadi penghubung antara Allah dan manusia. Peran ini dipercayakan oleh Yesus Kristus kepada mereka, sejak mereka memperoleh Sakramen Tahbisan. Mengingat begitu pentingnya peran seorang imam, mereka perlu dipersiapkan dalam masa pembinaan yang cukup panjang. Praksis pembinaan calon imam di Seminari Tinggi CM melibatkan lima dimensi pembinaan, yakni manusiawi, rohani, intelektual, pastoral, dan komunitas. Salah satu aspek yang dibahas dalam karya ilmiah ini adalah dimensi manusiawi. Fokus penelitian karya ilmiah ini terletak pada usaha untuk memperoleh koneksi antara praksis kerja harian para formandi Seminari Tinggi CM dengan Laborem Exercens artikel 26. Dalam merancang karya ilmiah ini, penulis menggunakan metode studi literatur. Berbagai sumber yang mendukung riset ini dikumpulkan oleh penulis untuk kemudian ditelaah secara kritis. Penulis menemukan bahwa artikel 26 pada Laborem Exercens memiliki kaitan erat dengan pembinaan dimensi manusiawi, dimana salah satu bentuknya adalah kerja harian. Kerja harian dipandang sebagai  kesempatan bagi para formandi untuk belajar banyak, mengembangkan bakat kemampuannya, beranjak keluar dari dirinya dan melampaui dirinya. Manfaat kerja tersebut sangat mendukung dimensi pembinaan manusiawi mereka.
