Introduction: The COVID-19 pandemic has created an urgent demand for research, which has spurred the development of enhanced biosafety protocols in biosafety level (BSL)-3 laboratories to safeguard against the risks associated with handling highly contagious pathogens. Laboratory management failures can pose significant hazards. Methods: An external system captured images of personnel entering a laboratory, which were then analyzed by an AI-based system to verify their compliance with personal protective equipment (PPE) regulations, thereby introducing an additional layer of protection. A deep learning model was trained to detect the presence of essential PPE items, such as clothing, masks, hoods, double-layer gloves, shoe covers, and respirators, ensuring adherence to World Health Organization (WHO) standards. The internal laboratory management system used a deep learning model to delineate alert zones and monitor compliance with the imposed safety protocols. Results: The external detection system was trained on a dataset consisting of 4112 images divided into 15 PPE compliance classes. The model achieved an accuracy of 97.52 % and a recall of 97.03 %. The identification results were presented in real time via a visual interface and simultaneously stored on the administrator's dashboard for future reference. We trained the internal management system on 3347 images, achieving 90 % accuracy and 85 % recall. The results were transmitted in JSON format to the internal monitoring system, which triggered alerts in response to violations of safe practices or alert zones. Real-time notifications were sent to the administrators when the safety thresholds were met. Conclusion: The BSL-3 laboratory monitoring system significantly reduces the risk of exposure to pathogens for personnel during laboratory operations. By ensuring the correct use of PPE and enhancing adherence to the imposed safety protocols, this system contributes to maintaining the integrity of BSL-3 facilities

The existence of aquatic plants has a significant influence on the biota living at wellspring. The osmotic pressure is significant research to understand the adaptation of the environment changing to organism physiology. This research aims to know the Osmotic Work Rate by comparing osmolarity water value to aquatic plant plasma. The research method is the descriptive analysis of laboratory test results. The water sample was taken from the seven locations of the wellspring. Osmotic work rate is taken from comparing the plasma osmolarity value of the aquatic plant to water Osmolarity. Osmotic work rate zero means osmoregulation patterns isosmotic. The osmotic work rate greater than zero implies osmoregulation patterns hyperosmotic regulatory and osmoregulation patterns hypo-osmotic regulatory if the Osmotic work rate is less than zero. The patterns are used from the seven locations of good springs are the same, osmoregulation patterns of Hyperosmotic regulatory to the environment because the plasma osmolarity of water plants is more significant than water osmolarity.

A number of methods have been proposed for causal effect estimation, yet few have demonstrated efficacy in handling data with complex structures, such as images. To fill this gap, we propose Causal Multi-task Deep Ensemble (CMDE), a novel framework that learns both shared and group-specific information from the study population. We provide proofs demonstrating equivalency of CDME to a multi-task Gaussian process (GP) with a coregionalization kernel a priori. Compared to multi-task GP, CMDE efficiently handles high-dimensional and multi-modal covariates and provides pointwise uncertainty estimates of causal effects. We evaluate our method across various types of datasets and tasks and find that CMDE outperforms state-of-the-art methods on a majority of these tasks. © 2023, CC BY.

Metformin is an antidiabetic drug that can be obtained easily in pharmacies/on the market, because it is traded freely, so people can easily buy and consume it. Ferrous metal, aluminum metal, and zinc metals are metal quite easy to find and are often used by the public. Metformin and Ferrous metal, aluminum metal and zinc metals are metal are quite familiar in the community. This research aims to deconcentrate metformin which can be obtained easily in pharmacies / on the market by electrolysis method, using ferrous metal, aluminum metal, and zinc metals are as an anode and carbon as the cathode. Electrolysis of metformin has been carried out using ferrous metal, aluminum metal, and zinc metal as an anode. The success of the electrolysis process was seen with a decrease in the sample COD index. In the case without the addition of electrolytes using ferrous metals, the COD index of the sample reduction was very low (9-17%). This research aims to increase the success of the electrolysis process, by adding various kinds of electrolytes, such as acetic acid (weak electrolytes), hydrochloric acid (strong electrolytes), sodium chloride and Fenton reagents. The addition of electrolytes can increase electrolysis yield significantly. The interaction between metformin during electrolysis is traced to the possibility of changes in the chromophore group (with UV-Visible spectra) and the functional group (with FTIR spectra) of the sample. From the research data obtained information that there is a decrease and shift in UV-Visible spectra and changes in functional groups after the electrolysis process occurs. The best electrolysis percentage is obtained, after adding NaCl solution and Fenton's reagent in the range of 50 -66%. © Published under licence by IOP Publishing Ltd.

The thermogravimetric-Fourier transform infrared (TG-FTIR) analysis was to explore the pyrolysis behavior of seven degrees of thermal aging home decoration PVC insulation copper cables. It was found that the most dangerous threshold for pyrolysis of insulation is 20 days of aging. The apparent activation energy of the insulation was estimated by the Flynn-Wall-Ozawa (FWO) method, and the degree of thermal aging has a greater effect on the apparent activation energy of the second pyrolysis stage. The first stage of pyrolysis was based on the D-ZLT3 and F models, and the second stage was based on the A and E models, which were determined by the Málek method. In addition, the release products of the pyrolysis process were counted. Finally, it should be noted that different degrees of thermal aging affect the pyrolysis behavior of cable insulation but have little effect on the pyrolysis mechanism. © 2023, The Authors.

Soybeans have experienced massive growth in trade due to diet transitions. Large imports reduce expected returns for soybean growers in importer countries, influencing occupational choices and potentially facilitating population mobility, though the distant correlation's impact remains unclear. We develop a framework integrating diet dynamics, trade indexes, and human mobility. We found: (1) dietary transition promotes human mobility through global soybean trade;(2) rural areas contribute far less than urban areas, illustrating decoupling between rural regions and international trade;(3) enhancing rural-trade coupling could improve dietary and crop flow in rural regions;(4) the study provides a new perspective on how dietary transition promotes human mobility. These findings help policymakers identify soybean trade strategies for socioeconomic development and formulate interventions to optimize population distribution. By addressing rural decoupling, we emphasize aligning rural areas with global trade to mitigate mobility pressures and socioeconomic disparities, without altering original terms. © 2025 The Authors

Background: Tartrazine (TAT) is a widely used food colorant dye, offering an orange-yellow hue in various products such as foods, cosmetics, and pharmaceuticals. Despite its popularity, TAT is banned in several countries due to its potential health risks, including respiratory issues, migraines, and skin allergies. Moreover, TAT is linked with adverse effects on human physiology, including mutagenicity, biliary cirrhosis, changes in liver and kidney functions, and neurodegeneration at varying doses. Consequently, the detection of this food additive is crucial for safeguarding human health and protecting aquatic organisms. Methods: In this study, a novel sensor was developed for the detection of TAT, utilizing a composite material made from nickel phosphide decorated with functionalized carbon nanofiber (Ni2P@f-CNF). The Ni2P@f-CNF was synthesized and characterized through several techniques, including X-ray diffraction, X-ray photoelectron spectroscopy, field emission-scanning electron microscopy, and elemental mapping. The composite was then integrated with a glassy carbon electrode to create a sensor. The sensor's performance was evaluated in terms of detection limit, linear range, selectivity, sensitivity, reproducibility, repeatability, and long-term stability. Main Findings: The developed Ni2P@f-CNF composite sensor displayed a lower detection limit of 0.011 µM and a broad linear range from 0.01 to 1875 µM. Its selectivity and sensitivity were exceptional, primarily due to the catalytic activity of the Ni2P@f-CNF composite towards TAT. The sensor also demonstrated excellent reproducibility, repeatability, and notable long-term stability. Importantly, when applied in real-world scenarios, the sensor successfully detected TAT in soft drink and liquid soap samples, yielding high recovery rates between 97.45 % to 99.37 % and 98.26 % to 99.01 %, respectively, underscoring its potential applicability in practical settings. © 2024 Taiwan Institute of Chemical Engineer
