Published: August 2024

Introduction. Many years of experience in design and operation of structures prove that the reliability of structures cannot be ensured by strength calculations alone. In addition to strength and stiffness of structures, their vibrations are often required to be considered. These types of calculations appear highly comprehensive, involving a large number of different factors to be taken into account. At present, as structures are becoming more and more complex, great attention is paid to seismic design, which is especially relevant for buildings subjected to high seismic loads. Engineering structures experience increased loads associated with the above-mentioned and other reasons. Free and forced vibrations of various elastic structures obtain a significant relevance among researchers as manifested by numerous publications on this issue.Aim. To present a complete mathematical problem for the two most common methods of end restraint, to determine natural frequency spectrum and eigenforms of beam vibrations.Materials and methods. The present study involves a beam of variable cross-section made of homogeneous material, subjected to transverse distributed load, which makes bending vibrations. Free and forced vibrations are described by differential equations. The homogeneous equation is solved first, then – the nonhomogeneous equation. The study involves application of D’Alembert’s principle, variable separation method, and test checks.Results. The authors obtained a fourth-order partial differential equation with constant coefficients and determined a natural frequency spectrum and eigenforms of vibrations. A high accuracy of the obtained results enables the characteristics of free and forced vibrations of beams to be determined in a shorter way with fewer calculations. Notably, the amplitude and eigenform of forced vibrations of beams appear dependent on the proximity of the disturbing frequency to the eigenvalues and the phase change of components in vector disturbance process.Conclusions. The authors advanced hypotheses about a dependence between the damping and linear viscous friction coefficients as well as about the constancy of damping coefficient for all eigenvalues.
Variability of strength and stiffness assessment for non-profile beam structures
Authors: Kulagin A. V. 
Published: August 2024

Introduction. Traditional ways to increase the structural strength and stiffness of beams are now almost exhausted, and optimization of production and operation technologies is mostly based on the use of new materials and increasing their reliability as bearing elements of a complex geometric profile. Bearing elements of building structures operate under high loads and, even despite their predominantly static nature, experience a complex volumetric stress and strain state, which can scarcely ever be confirmed empirically and statistically.Aim. To propose an approach to assessing the strength and stiffness of beam structures operating under conditions of transverse bending of a complex geometric profile.Materials and methods. Classical energy methods, including Castigliano, Maxwell–Mohr and Vereshchagin methods (moment area method), have been used to assess the strength and stiffness of non-profile beam structures, initial parameters, differential equations of the deflection curve.Results. The similarity parameters (fitting criteria) of Mises–Hencky and Zhurkov reflect the behavior of a brittle or plastic beam material reasonably well. These characteristics are proposed to be combined in the Arrhenius–Zhurkov durability functions.Conclusions. The dependencies given in the calculations can be recommended for improving the flexural static and fatigue strength, as well as the stiffness of the bearing elements of building structures.
Mixing and mingling in visual working memory: Inter-item competition is feature-specific during encoding and feature-general during maintenance
Authors: Wennberg Janna W. , Serences John T. 
Published: August 2024

AbstractVisual working memory (WM) is a central cognitive ability but is capacity-limited due to competition between remembered items. Understanding whether inter-item competition depends on the similarity of the features being remembered has important implications for determining if competition occurs in sensory or post-sensory stages of processing. Experiment 1 compared the precision of WM across homogeneous displays, where items belonged to the same feature type (e.g., colorful circles), and heterogeneous displays (e.g., colorful circles and oriented bars). Performance was better for heterogeneous displays, suggesting a feature-specific component of interference. However, Experiment 2 used a retro-cueing task to isolate encoding from online maintenance and revealed that inter-item competition during storage was not feature-specific. The data support recent models of WM in which inter-item interference – and hence capacity limits in WM – occurs in higher-order structures that receive convergent input from a diverse array of feature-specific representations.

Authors: Niehorster Diederick C. , Gullberg Marianne , Nyström Marcus 
Published: August 2024

AbstractWhen lab resources are shared among multiple research projects, issues such as experimental integrity, replicability, and data safety become important. Different research projects often need different software and settings that may well conflict with one another, and data collected for one project may not be safeguarded from exposure to researchers from other projects. In this paper we provide an infrastructure design and an open-source tool, labManager, that render multi-user lab facilities in the behavioral sciences accessible to research projects with widely varying needs. The solutions proposed ensure ease of management while simultaneously offering maximum flexibility by providing research projects with fully separated bare metal environments. This solution also ensures that collected data is kept separate, and compliant with relevant ethical standards and regulations such as General Data Protection Regulation (GDPR) legislation. Furthermore, we discuss preconditions for running shared lab facilities and provide practical advice.

A severe impact of human-induced climate change is the global decrease in crop yields, threatening the United Nations sustainable development goal (SDG) to end hunger, achieve food security, improve nutrition, and promote sustainable agriculture (SDG 2: “Zero Hunger Goal”).
Decision-making on appropriate mitigation strategies requires data integration from heterogeneous data-rich contexts including Earth observation (EO), biodiversity monitoring, gene banks as well as socio-economic data. Accordingly, large-scale initiatives for thematic data spaces, such as the European projects Destination Earth (DestinE) and the Green Deal Data Space, have been launched.
Underutilized crops and crop wild relatives (CWR) can contribute to mitigating the impacts of climate change since their greater genetic diversity allows adaptation of agro-food sources to extreme weather events such as flooding and drought or emerging crop pests.
Within the framework of Biodiversity Digital Twin (BioDT), a prototype digital twin for crop genetic resources modeling is under development. This prototype combines the scanning of genetic resources of CWRs and traditional cultivars for promising pest resistance and abiotic tolerance traits with advanced species distribution modeling and actual climate scenarios from EO. The aim is to generate habitat suitability maps and identify potential areas where relevant populations are potentially growing (Chala et al. 2024).
The talk gives an overview of data models used to facilitate the required interoperability of both Earth models and environmental data within and across different data spaces such as the DestinE Data Lake (Duatis Juarez et al. 2023). Based on our findings from the use case of agrobiodiversity digital twins, we will discuss approaches for processing machine-actionable digital objects (Fig. 1) containing workflow information (i.e., in the Common Workflow Language format, Crusoe et al. 2022), and for sharing resulting research data in a FAIR (Findable, Accessible, Interoperable, and Reusable) manner by leveraging on so-called webby FAIR Digital Objects involving Research Object Crate (RO-Crate, Soiland-Reyes et al. 2022), FAIR Signposting (Soiland-Reyes et al. 2024) and schema.org and its Bioschemas extension respectively (Castro et al. 2020),

Study’s Novelty/Excerpt

This study investigates the bacteriological safety of ready-to-eat (RTE) vegetables in the Gombe metropolis, Nigeria, focusing on their contamination with Salmonella enterica.
It identifies a significant contamination rate of 36% and establishes a strong association between poor handling practices and the presence of Salmonella, providing critical insights into the public health risks posed by these RTE vegetables.
The study's findings on antibiotic sensitivity patterns of Salmonella isolates further highlight the urgent need for targeted health interventions and improved food safety practices to mitigate typhoid transmission in this region.

Full Abstract
The worldwide twelve-monthly typhoid fever manifestations range amid 16–20 million ailments, ensuing in roughly 600,000 human mortalities, particularly amongst low-income and middle-income nations. Numerous typhoid outbreaks had previously been linked to contaminated vegetables. In the Gombe metropolis of Gombe state, Nigeria, ready-to-eat (RTE) vegetables are hawked around and handled using unhygienic methods. Hence, this study aimed to investigate and bridge the knowledge gap regarding the bacteriological safety of these ready-to-eat vegetables and the risk factors for their contamination with Salmonella enterica. A total of 100 samples were sourced from various locations in the Gombe metropolis, homogenized and inoculated on nutrient agar, Salmonella-Shigella agar, and MacConkey agar. Identification was executed by utilizing standard procedures of Gram’s staining and biochemical tests. Antibiotic sensitivity assessment was executed per CLSI guidelines, a questionnaire was utilized to acquire data for ascertaining the association amongst handling and contamination of the RTE vegetable salad, and this data was analyzed using a chi-square test. Findings revealed 36% of the samples were contaminated with Salmonella enterica, which were grey-white on nutrient agar, colorless colonies with black centers on Salmonella-Shigella agar, non-lactose fermenters on MacConkey agar, Gram-negative rod-shaped, motility and catalase positive, indole negative, urease negative, citrate negative, and KIA positive. Sensitivity showed the isolates were 100% sensitive to ofloxacin and chloramphenicol, 100% resistant to ceftazidime, cotrimoxazole, and ceftriaxone, but 95.4% were sensitive and 4.6% resistant to ampicillin. Data analysis revealed a significant association between contamination and some handling practices. The findings in this study have shown that the RTE vegetable salad is a source of public health hazard to the community, and also the information generated by this study can be used to create targeted health interventions against the RTE vegetable salad-transmitted typhoid in Gombe, Nigeria.

Study’s Novelty/Excerpt

This study investigates into the microbial contamination of second-hand clothes, highlighting their potential role in infection transmission.
The research highlights the significant phosphate-solubilizing activity of these native strains, which enhances phosphorus availability to plants through the secretion of organic acids and enzymes.
The findings underscore the need for public health interventions, including the washing and disinfection of second-hand clothing to mitigate the risk of spreading antibiotic-resistant pathogens.

Full Abstract
Used clothes can potentially be an element in the chain of infection transmission during normal daily activities. Second-hand wear is among such used clothes purchased by many people and used directly without considering any attending health implications. This study, therefore, examined the level of microbial contamination of second-hand clothes and the association between the different categories of the clothes and microbial contaminants. Second-hand clothes such as shirts, trousers, vests, socks, and shoes were bought from three Markets in Girei, Yola North and Yola South. Isolation of organisms was carried out via Standard Plate Count. Isolates were identified using morphology and appropriate biochemical methods. A chi-square test (P ≤ 0.05 significant) was done to analyze some of the data obtained. Antibiotic susceptibility of the bacterial isolates was also determined using the Kirby-Bauer method. The most frequently isolated bacteria were Staphylococcus aureus. Other bacteria isolated were Pseudomonas spp and E. coli. A total of four fungal species were isolated. These are Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger and Trichophyton rubrum. Trousers had the highest bacterial count (1.10 x103 CFU/mL) and fungal count (8.00 x104 CFU/mL). The data obtained shows no significant association between fungal species and the categories of clothes with (P = 0.15), but there is a significant association between bacterial species isolated and the categories of clothes analyzed (P = 0.02). S. aureus was susceptible to ciprofloxacin (100%) and erythromycin (92.8%), while Pseudomonas sp and E. coli were most susceptible to ciprofloxacin and sparfloxacin (100%). The least susceptibility was observed with amoxicillin and sulfamethoxazole-trimethoprim. It became obvious that these clothes are possible carriers of antibiotic-resistant pathogens for skin and other infections. Washing and disinfecting second-hand wear before use may be important in minimizing the potential health implications associated with the isolated pathogens.

Study’s Novelty/Excerpt

This study evaluates the combined effects of Turmeric, Coriander, and Mint (TCM) leaves on nutritional, functional, and antioxidant properties in polyherbal formulations, showing their superior glucose absorption capacity and antioxidant activity compared to single herbs.
The research highlights a significant nutritional shift in the TCM formulation, providing evidence for its enhanced efficacy in nutraceutical applications.
These findings show the potential of TCM as a novel botanical candidate for safe and effective pharmaceutical development.

Full Abstract
Conventional drugs have numerous side effects, toxicity, and microbial resistance, making them unsafe for consumption. Polyherbal formulations are popular due to their potency, low cost, clinical efficacy, safety, and success in chronic conditions. The study aims to evaluate the proximate, vitamin, functional, and antioxidant activity of polyherbal formulations of Turmeric, Coriander, and mint (TCM) leaves as potential botanical candidates for pharmaceutical screening. Thus, addressing these issues and improving access to drugs for individuals by focusing on polyherbal formulations (PHF) is a potential solution. All analyses conducted were determined according to standard assay guidelines. The proximate analysis shows no significant difference among the formulations (p > 0.05), with TCM showing a nutritional profile shift because of the combination of the herbs rather than single herbs. In the vitamin composition, Vitamin A displays a pattern among the formulations, with TC and CM showing higher values than TM and TCM, which are, in turn, better than the single herbs. Vitamin C fluctuates across the formulations. TM displays higher, while T shows the lowest. Vitamin E content remains relatively stable among the formulations with a difference from the single herbs. In the functional properties, GAC displays notable variations among the formulations. TCM exhibits the highest GAC at 14.7 %, indicating its superior ability to absorb glucose. TC, CM, TM, and the single herbs show a comparatively lower GAC value. WAC also varies among the formulations. TCM displays lower WAC compared to TC, TM and CM. The single herbs show the lowest WAC. OAC shows intriguing trends across the formulations. TCM and TC exhibit similar OAC, while CM shows a slightly higher OAC, and TM displays better than single herbs, showing no significant difference (p > 0.05). In the antioxidant Activity, TCM shows lightly higher scavenging activity in 40, 80 and 120 mg/mL concentrations than other formulations. The outcome of this study has led us to conclude that employing safe combinations of these herbal formulations for the production of nutraceuticals is recommended.
