Published: September 2023

Maize is frequently contaminated with multiple mycotoxins, especially those produced by Aspergillus flavus and Fusarium verticillioides. As mycotoxin contamination is a critical factor that destabilizes global food safety, the current review provides an updated overview of the (co-)occurrence of A. flavus and F. verticillioides and (co-)contamination of aflatoxin B1 (AFB1) and fumonisin B1 (FB1) in maize. Furthermore, it summarizes their interactions in maize. The gathered data predict the (co-)occurrence and virulence of A. flavus and F. verticillioides would increase worldwide, especially in European cold climate countries. Studies on the interaction of both fungi regarding their growth mainly showed antagonistic interactions in vitro or in planta conditions. However, the (co-)contamination of AFB1 and FB1 has risen worldwide in the last decade. Primarily, this co-contamination increased by 32% in Europe (2010–2020 vs. 1992–2009). This implies that fungi and mycotoxins would severely threaten European-grown maize.

Authors: Xiao Huogen , Meng Baozhong
Published: September 2023

French-American hybrids and North American grape species play a significant role in Canada’s grape and wine industry. Unfortunately, the occurrence of viruses and viral diseases among these locally important non-vinifera grapes remains understudied. We report here the results from a large-scale survey to assess the prevalence of 14 viruses among 533 composite samples representing 2665 vines from seven French-American hybrid wine grape cultivars, two North American juice grape cultivars (Concord and Niagara), and the table grape cultivar Sovereign coronation. Based on reverse transcription polymerase chain reaction (RT-PCR) assays, ten viruses were detected. Grapevine rupestris stem pitting-associated virus, grapevine leafroll-associated virus 3, grapevine Pinot gris virus and grapevine red blotch virus were detected with the highest frequency. As expected, mixed infections were common; 62% of the samples contained two or more viruses. Overall, hybrid wine grapes were infected with more viruses and a higher prevalence of individual viruses than juice and table grapes. To validate these findings and to refine the virome of these non-European grapes, high-throughput sequencing (HTS) analyses of five composite samples representing each category of grapevine cultivars was performed. Results from HTS agreed with those from RT-PCR. Importantly, Vidal, a widely grown white-wine grape with international recognition due to its use in the award-winning icewine, is host to 14 viruses, four of which comprise multiple and distinct genetic variants. This comprehensive survey represents the most extensive examination of viruses among French-American hybrids and North American grapes to date.

Published: September 2023

This research focused on the rubber bushings of the rear sub-frame in an electric vehicle. A dynamic model was developed to represent the bushing, incorporating an elastic element, a frictional element, and a viscoelastic element arranged in series using a fractional-order Maxwell and a Kelvin–Voigt model. To identify the parameters of the bushing model, an improved adaptive chaotic particle swarm optimization algorithm was employed, in conjunction with dynamic stiffness test data obtained at an amplitude of 0.2 mm. The test data obtained at different amplitudes (0.2 mm, 0.3 mm, 0.5 mm, and 1 mm) were fitted to the model, resulting in fitting errors of 1.13%, 4.07%, 4.42%, and 28.82%, respectively, when compared to the corresponding test data in order to enhance the accuracy of the model fitting; the Sobol sensitivity analysis method was utilized to analyze the parameter sensitivity of the model. Following the analysis, the parameters α, β, and k2, which exhibited high sensitivity, were re-identified. This re-identification process led to a reduction in the fitting error at the 1 mm amplitude to 7.45%. The improved accuracy of the model plays a crucial role in enhancing the simulation accuracy of design of experiments (DOE) analysis and verifying the vehicle’s performance under various conditions, taking into account the influence of the bushing.

Published: September 2023

The increase in economic activities and the industrialization of countries have caused the growth of pollution created by waste and sewage. In particular, the textile industry produces large amounts of liquid contaminants due to the large amounts of water employed during the production of fabrics. In addition, dyes are another category of organic compound used in many industries, such as pharmaceuticals and rubber making. The presence of limitations in physico-chemical methods for the degradation of various dyes has stimulated the interest of researchers worldwide. One of the most economical ways is the use of photocatalytic decomposition under UV light radiation by green nanoparticles (NPs). In recent years, various metal NPs have been made using the green method that is cost-effective, eco-friendly, safe, and simple. Selenium (Se) is a crucial semiconductor metal that is widely utilized for its outstanding photovoltaic and optoelectronic attributes. Due to the excellent physical characteristics of Se, such as thermo-conductivity, anisotropy, and high photoconductivity, it has been used for removing various organic dyes. Hence, green SeNPs have attracted much attention in the catalytic decomposition process. The current review focuses on providing comprehensive studies concerning the degradation or reduction of various organic dyes through green SeNPs as an effective and efficient method and their mechanisms. It highlights the importance of utilizing green chemistry and catalytic properties. The aim is to benefit researchers from both academic and industrial backgrounds.

Published: September 2023

Background: The ongoing COVID-19 pandemic affects several aspects of food safety and food delivery hygiene for online food delivery applications (OFDAs). Several previous studies conducted at various times during the COVID-19 pandemic have yielded interesting results. This study aimed to determine and analyze whether perceptions of food safety and food delivery hygiene are short-term and long-term predictors of behavioral intention to use OFDAs. Methods: A quantitative approach and structural modeling were used in this study. SmartPLS is used to analyze five direct and two mediating effects of the variables used in this study. The data sample consists of OFDA users in Greater Jakarta during the second year of the COVID-19 pandemic. Results: Perceived food safety has a significant effect on behavioral intention to use these applications but does not affect behavioral intention to continue using these applications. Perceived food delivery hygiene does not influence using these apps for either short-term or long-term behavioral purposes. Experience with these apps related to food safety and food delivery hygiene during a pandemic can be indicative of their long-term viability. The mediating effect of behavioral intention to use on behavioral intention to continue using these apps affects perceived food safety but not food delivery hygiene. Conclusion: By emphasizing vaccination and boosting against COVID-19, providing hand sanitizer, and preserving the cleanliness and integrity of food packaging, the findings of this study can be put into practice towards the sustainable usage of OFDAs.

Authors: Kumar Abhishek , Chandrahasan Ravichandran
Published: September 2023

Background: Heavy metals are one of the global environmental challenges from the informal disposal of electronic waste, especially after the post-COVID phase. In the present study, the concentration of three heavy metals (Pb, Cd, and Cr) in the feathers of Corvus splendens, Passer domesticus and roosting sites at Bellandur Lake, Bengaluru, India were analyzed. Methods: A total of nine sediment samples (0-15 cm) were collected from the roosting sites and stored in polyethylene bags, and nine samples of C. splendens and P. domesticus bird shedding feathers through the molting phenomenon were collected naturally to avoid stimuli that can create conflict for the bird. The samples were collected early morning from 5.00 a.m. to 9 a.m. To determine heavy metals (Pb, Cd, and Cr) in feathers and sediments, the samples were digested and subjected to AAS and inductively coupled plasma-mass spectroscopy (ICP-MS). Furthermore, the generalized linear model was analyzed to test the covariance structure of bird diversity. Results: The Pearson’s correlation is found to be significant (P<0.05) for contaminated sediments and the feathers of the bird. Analysis of variance for the difference in the concentration of heavy metals within the bird’s species feathers was not statistically significant (P<0.05). Conclusion: The feathers of C. splendens and P. domesticus bird species are associated with blood vessels and heavy metals deposited in the blood through the food chain, which are contaminated with heavy metals. C. Splendens feathers were more contaminated with Cr, Pb, and Cd compared to P. domesticus feathers bird species.

Published: September 2023

Background: The energy crisis is a growing problem around the world, requiring the creation of alternative energy sources that can generate less carbon dioxide and benefit the ecosystem. Reutilization of wastewater is becoming the emerging energy solution. Wastewater contains a large amount of organic matter that can be oxidized in microbial fuel cells (MFCs) to produce electricity. MFCs use biodegradable materials to create energy in the presence of microorganisms. Methods: Purposive sampling technique was employed to collect samples from critical polluting sources. The samples were certainly maintained in a refrigerator at 4°C. Several mixes for sample were prepared and tested analytically- for physio-chemical and bacteriological characterizations of each substrate status at pre- and post-treatment stages. Electricity generating capacity of MFCs that employing different substrates was investigated experimentally using batch reactors. The cross-sectional methodology was employed to study possible power generation. Results: The maximum voltage output of 118.93, 144.84, and 89.76 mV were produced keeping the resistance unlimited for MFC1 (urine substrate), MFC2 (blackwater substrate), and MFC3 (graywater substrate), respectively. MFC that utilized graywater as a substrate brought the tiniest quantity of electricity; however, it stood the most stable. The highest COD reduction (65.83%) in the process was reported in urine substrate and the highest BOD5 removal (69.18%) was reported in black water substrate. Conclusion: The experimental results provided a promising indication of MFCs viability, providing hope for future power generation and alternative wastewater treatment option in developing countries.

Authors: Nalbur Berrak Erol , Yavaş Özcan
Published: September 2023

Background: Natural wastewater treatment systems (NWTSs) in small villages are a major challenge for European water authorities. With growing social demands for environmental practices, evaluating the feasibility and environmental impact of low-cost treatment systems for small residential areas is essential. Methods: To address this challenge, this study was conducted to evaluate 10 NWTSs seasonally in rural areas of Bursa, Turkey. Authorities over the facilities permitted the examination of workable, low-cost effluent management options. Also, using Open-LCA software based on ReCiPe MidPoint (H) version 1.67, these plants’ effects on global warming, Phosphorus-depletion, human toxicity, marine eutrophication, and freshwater eutrophication were examined. Results: According to the LCA findings, Deydinler NWTS had a greater impact across all three effect areas (freshwater eutrophication, marine eutrophication, and human toxicity), ranging from 11 to 41%. Pinar and Yenice facilities, however, had 26% and 27% larger impacts in the same two impacts (marine eutrophication and human toxicity). These systems performed on average at 67%, 50%, and 58% chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) elimination, respectively. Conclusion: According to the findings, 10 NWTSs have a treatment efficiency of about 70%. NWTSs are possibilities for decentralized wastewater treatment in small residential areas that are both cost-effective and environmentally favorable. By treating organic pollution naturally, without chemicals, and with minimal energy use, they lessen their negative environmental effects. The main findings of this study will be useful for academics in determining future research areas and identifying whom they might consult to help design carbon footprint of NWTS and future carbon reduction objectives.

Published: September 2023

Modern research in the forestry industry is increasingly focused on digitalization and remote sensingEarth. One of the promising areas is the formation of a digital terrain model and its subsequent study. In this regard, the purpose of the work is to identify relationships and establish dependencies between the parameters of the relief and forest conditions for the accelerated determination of key forestry and landscape characteristics, incl. using remote methods. The objects of the study were forest plantations located in the Prigorodnoye forestry of the Voronezh region. The formation of a digital terrain model was carried out on the basis of aviation and space monitoring materials using specialized software. In the course of the work, features of the terrain were identified that potentially affect the formation of growing conditions, and tabular analytical materials were compiled that allow taking into account landscape factors on a per-allocation basis. Data on the average slope steepness, slope exposure azimuth and height above sea level of each section in degrees were obtained and their statistical parameters were analyzed.A correlation was established between the forest typological component, which characterizes the moisture content of the soil and the height of the site above sea level (0.23-0.29), as well as the steepness of the slopes (0.30-0.32). The results of the research indicate that such a trend can be traced even with insignificant elevation changes and slope steepness, which are typical for the Prigorodnoye forestry. Wetter soil conditions in the territory of the study region (A3, B3, C3) are located on micro depressions or have groundwater close to the surface. The revealed pattern will make it possible to carry out an accelerated determination of growing conditions by a remote method based on terrain indicators and consider the proposed methods as potential tools for forest accounting.
Early Iranian Riders and Cavarly

Published: September 2023

The expansion of the Iranian peoples in first centuries of the 1st millennium BCE coincides with the creation and further development of the cavalry warfare in western Eurasia, as well as with the creation of the pastoral nomadic life-style which dominated the Great Steppe for millennia to come. The mounted warriors replaced the light chariots which dominated the Bronze Age battlefields which required perfect horsemanship however application of the recurved, double reflex. composite bow for mounted combat seemed another important factor in development of the cavalry force. Mounted archery which doubled the fire power of the mobile troops, earlier dominated by the chariots triggered the evolution of the various forms of cavalry, both as a response to a threat of the horse archers and independent forces used by the sedentary societies. Iranian contribution in spreading (and most likely invention) of the new technology is undeniable. Although horse riding and recurved composite bows were known earlier they could not overcome the power of the chariot force separately. Only the combination of the factors allowed fielding large and efficient cavalry troops as was practiced by the Scythians and became the success factor for the Achaemenid Empire. Survival of the chariots as late as the Seleucid times was possible because of changing their tactical function from the highly mobile shooting platform to heavy, at least partially, armored terror and shock weapon.

Published: September 2023

This research focuses on the wear analysis of heavy vehicle gearbox systems, with particular emphasis on the case study of operational load fluctuations as a factor influencing wear rates. Heavy vehicles play a central role in various industries, and gearboxes are key components that affect operational performance and reliability. In this study, we collected operational data from various heavy vehicles operating under various conditions and environments. Through rigorous statistical analysis, we were able to identify a significant relationship between operational load fluctuations and gearbox wear rates. The results indicate that an increase in operational load fluctuations can proportionally increase the wear rate. These results have important implications in the development of smarter and more efficient maintenance strategies for heavy vehicles, which can reduce unexpected maintenance costs and increase gearbox service life. In addition, this study also confirmed that the basic assumptions in regression analysis, such as normality of residuals, homoscedasticity, and independence of residuals, were well met. This validates the results of the regression analysis and provides a solid basis for decision-making in the context of heavy vehicle maintenance. Recommendations for further research development include more detailed data collection, the use of more advanced analysis methods, and the application of sensor and IoT technologies for real-time monitoring. With continued research in this area, we can advance our understanding of wear on heavy vehicle gearboxes and support the development of smarter maintenance strategies in the heavy transportation industry.

A nozzle device featuring a micro-electromechanical system (MEMS) was developed to realize a series of advanced micromanipulation steps for capturing pollens from flower stamen and fixing them in arrays on culture media without cell damage. The MEMS nozzle, which has an array of through-holes with counterbores, was fabricated by the photolithography and Si etching. During the manipulation, the pollen in the air was captured in the counterbores due to the negative pressure applied from the nozzle backside. When the device with the captured pollen was moved into the liquid culture media of the gelatin, the liquid was sucked into each counterbore, so that the captured pollen was covered. By cooling the culture media down and switching off negative pressure, the controlled release of sucked cells without damage and the fixation in array on solid culture media were achieved. Through experiments implemented by the nozzle, the positive effect of plasma-treated water on the pollen growth was verified. The microarray strategy presented in this work made the cell experiments and result analysis more effective, especially for the plasma bio-applications.

ASSÉDIO MORAL NO TRABALHO

Published: September 2023

Neste artigo é proposta uma análise sobre os reflexos do assédio moral em trabalhadores que buscaram auxílio em sindicato e escritórios de advocacia de uma cidade do interior de Minas Gerais. A metodologia utilizada foi uma revisão de literatura sobre o tema e a aplicação de questionários semi-estruturados que inferem sobre as características do assédio moral e suas consequências em relação ao trabalhador vitimado. Como resultado confirmou-se as hipóteses levantadas acerca do assunto nos trabalhadores locais, sendo o estresse o principal sintoma indicado pelos entrevistados, o desencadeamento da violência majoritariamente provocada por parte do superior hierárquico, os indivíduos expostos a situações de assédio desenvolvem algum tipo de psicopatologia e a maior incidência de assédio é no gênero feminino. Concluiu-se que a violência moral derivada das interações sociais e laborais não é somente um problema individual, mas um “assédio organizacional”, que se desenvolve em função de práticas agressivas ditadas pela produtividade a qualquer custo em detrimento de relações interpessoais razoáveis.

Objetivo do presente estudo foi relatar um caso de reabilitação de uma senhora idosa, 90 anos de idade, viúva, etnia branca, com osteoporose primária. A paciente sofreu queda uma pequena escada de cinco degraus, com corrimão em ambos os lados, dentro de um estabelecimento comercial no dia em julho de 2022. Como consequência da queda a idosa sofreu cinco fraturas distribuídas nos lados direito e esquerdo do quadril. Após a queda a idosa foi encaminhada através de uma ambulância para um hospital referência na cidade de Campinas, SP, Brasil. A equipe médica optou por tratamento conservador, ou seja, repouso e sem intervenção cirúrgica, dada a idade e as comorbidades da paciente. Ao quinto dia após a queda a paciente foi encaminhada para sua residência, já equipada com cama hospitalar, colchão inflável anti escaras, luz infravermelho e acompanhamento 24 horas por dia por enfermeira alto padrão e auxiliares, além de fisioterapeuta, exames de sangue, RX e consultas com ortopedista realizadas periodicamente nesse local. A mesma teve permanente apoio por parte de seus familiares e amigos, muito especialmente, no suporte psicológico e afetivo diante da situação. Após 45 dias a paciente voltou a ficar na posição sentada, apoiando os pés no solo e passou a utilizar cadeira de rodas. Durante todo o processo a mesma tomou suplementação alimentar para auxiliar na recuperação das fraturas e ficou pelo menos 40 minutos por dia com foco de luz infravermelha a 40 centímetros do quadril e do joelho. Contrações isométricas diárias a partir da chegada da paciente em sua residência e sessões de fisioterapia de quatro vezes por semana, que progrediram gradativamente de modo a garantir a melhoria da mobilidade articular no tornozelo, joelho e por último no quadril. Após 4 meses e meio, no início de dezembro a paciente já estava caminhando sozinha, inicialmente, com auxílio de uma bengala. Em ambientes fora de uma casa a mesma sempre utiliza a bengala para ter um ponto de apoio adicional.
