Prototype Development of a Real-Time Monitoring System Based on Android and Cloud Database for Textile Non-Thermal Plasma Treatment The textile modification process using plasma treatment requires accurate monitoring of gas species generated during operation; however, no system is currently available to measure these gas concentrations in real time. To address this gap, this study develops a plasma gas monitoring system for textile material modification, using experimental data obtained from laboratory tests conducted in 2024. The research employs a practical prototyping approach consisting of four stages: requirement identification, system design, prototype construction, and performance validation. The system is designed to continuously record plasma-generated gas concentrations and store the data in an internet-based database. The prototype consists of two main components: (1) a sensing unit built on an Arduino Uno microcontroller integrated with DHT-11 and MQ-131 sensors for measuring temperature, humidity, and ozone concentration, and (2) a data management platform using Google Spreadsheet connected to a mobile application to enable real-time monitoring and control. Evaluation results show that the monitoring tool achieved a Mean Absolute Error (MAE) of 0.6625 ppm, indicating that the system provides reasonably accurate measurements for initial validation. As this assessment is preliminary, future studies should employ a larger dataset to increase statistical robustness and further verify system performance. Overall, the findings contribute to the development of an accessible, Android-based plasma treatment monitoring system capable of supporting real-time monitoring in textile material modification applications.

Checklist of marine pelagic diatoms from the Turkish side of the Aegean Sea This study presents a comprehensive checklist of marine diatoms recorded along the Turkish coast of the Aegean Sea, based on the evaluation of 41 literature studies. A total of 194 diatom species, belonging to 75 genera, were identified in the pelagic waters of the region, with 32 species recognized as harmful. Among them, several species exhibited bloom events or reached high cell concentrations. The study also highlights significant research gaps, particularly the limited application of molecular techniques and some species are known to have domoic acid-producing potential, but their toxicity remains unexamined in this region due to the lack of dedicated studies. Future research should prioritize integrating molecular methods and domoic acid analyses to improve species identification, assess harmful algal bloom (HAB) risks, and strengthen long-term monitoring strategies. Furthermore, regularly updating species checklists is essential for developing comprehensive datasets, enhancing biodiversity assessments, and advancing phytoplankton research along the Turkish coast of the Aegean Sea.

Monte Carlo calculation of 119Sb microscale absorbed dose using cascaded and averaged Auger electron spectra &lt;p&gt;Radionuclides decaying by electron capture or internal transition produce a large number of Auger electrons in a cascade that follows their radioactive decay. A shortlist of the most potent Auger electron-emitters has appeared in the literature including &lt;sup&gt;103m&lt;/sup&gt;Rh, &lt;sup&gt;103&lt;/sup&gt;Pd, &lt;sup&gt;111&lt;/sup&gt;In, &lt;sup&gt;119&lt;/sup&gt;Sb, &lt;sup&gt;123&lt;/sup&gt;I, &lt;sup&gt;125&lt;/sup&gt;I, &lt;sup&gt;165&lt;/sup&gt;Er, and &lt;sup&gt;197&lt;/sup&gt;Hg. Among them, &lt;sup&gt;119&lt;/sup&gt;Sb has been identified as the most potent for targeting micrometastases, yielding several tens of Auger electrons per decay with energies from a few eV up to 30 keV. In this paper, we recalculate Auger, Coster-Kronig, and super Coster-Kronig yields and transition probabilities as subshell-normalized relative transition probabilities and develop a new method to create radionuclide sources in TOPAS Monte Carlo, the code for which has been made publicly available. We then apply our method to encode the Auger electron spectra of &lt;sup&gt;119&lt;/sup&gt;Sb from MIRD RADTABS and EADL into TOPAS and calculate the absorbed dose to water volumes of radius 10 nm up to 10 μm, finding that the averaged MIRD Auger electron spectrum underestimates the absorbed dose by a factor of 20 to 50 on this scale. We show that this result is not isolated to &lt;sup&gt;119&lt;/sup&gt;Sb and conclude that either the cascaded MIRD or EADL spectrum should be used for accurate microscale dosimetry. We compare with results obtained using the built-in Geant4 Atomic Relaxation for &lt;sup&gt;119&lt;/sup&gt;Sb in TOPAS and find an unexpected continuum of low-energy electrons but no excess absorbed dose relative to either MIRD or EADL. We show that 119Sb does not produce more absorbed dose in microscale volumes than &lt;sup&gt;103m&lt;/sup&gt;Rh, &lt;sup&gt;103&lt;/sup&gt;Pd, &lt;sup&gt;111&lt;/sup&gt;In, &lt;sup&gt;123&lt;/sup&gt;I, &lt;sup&gt;125&lt;/sup&gt;I, &lt;sup&gt;165&lt;/sup&gt;Er, or &lt;sup&gt;197&lt;/sup&gt;Hg, warranting future microdosimetry calculations of RBE and DNA damage to understand whether &lt;sup&gt;119&lt;/sup&gt;Sb is the most potent Auger electron-emitter, as claimed in the literature.&lt;/p&gt; Monte Carlo method ; Microscale chemistry ; Electron ; Spectral line ; Auger electron spectroscopy ; Computational physics ; Auger ; Physics ; Statistical physics ; Atomic physics ; Nuclear physics ; Mathematics ; Statistics ; Quantum mechanics Electron and X-Ray Spectroscopy Techniques ; Nuclear Materials and Properties ; Catalytic Processes in Materials Science

Comparison Of The Antibacterial Activity Of Palm Kernel Oil (PKO) &amp; Virgin Coconut Oil (VCO) Against Pseudomonas Aeruginosa Bacteria Pseudomonas aeruginosa, a gram-negative bacterium, is a significant cause of nosocomial infections and exhibits high levels of multidrug resistance, necessitating the exploration of alternative antibacterial agents. This study investigates the antibacterial activity of Palm Kernel Oil (PKO) and Virgin Coconut Oil (VCO) against Pseudomonas aeruginosa, employing a true experimental post-test design with microdilution and agar dilution methods. Conducted at the Universitas Muslim Indonesia, the study determined the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of PKO, VCO, and gentamicin. Results revealed that PKO had an MIC of 4096 µg/mL and an MBC of 8192 µg/mL, while VCO exhibited an MIC of 2048 µg/mL and an MBC of 4096 µg/mL. Gentamicin, used as a control, demonstrated superior antibacterial effectiveness with an MIC of 2 µg/mL and an MBC of 4 µg/mL. Statistical analysis indicated that VCO, with its higher lauric and myristic acid content, was more effective than PKO in inhibiting bacterial growth, although both oils were less effective than gentamicin. The study highlights the potential of VCO as a natural antibacterial agent, suggesting further research to optimize its efficacy through formulation modifications and combinations with other antimicrobial agents. Additionally, evaluating the effectiveness of VCO and gentamicin against other bacterial strains is recommended to expand the understanding of VCO's antibacterial capabilities. These findings contribute to the growing body of evidence supporting the use of natural products in combating antibiotic-resistant infections.

Untersuchungen zur biokompatiblen Beladung von Monozyten mit Eisenoxidnanopartikeln fur die magnetische Steuerung Monozyten sind Zellen des angeborenen Immunsystems, die im Blut zirkulieren und bei Infektionen ins Gewebe auswandern, wo sie zu Makrophagen oder dendritischen Zellen ausdifferenzieren. Im Blut haben Monozyten drei Hauptfunktionen zur Bekämpfung von Pathogenen, nämlich Phagozytose, Antigenpräsentation und Zytokinproduktion. Als Phagozyten können Monozyten nicht nur Pathogene, sondern auch andere Teilchen wie Nanopartikel, aufnehmen. Die gezielte Beladung von Zellen mit superparamagnetischen Eisenoxidnanopartikeln (SPIONs) eröffnet viele Anwendungsmöglichkeiten, wie die magnetische Steuerung von Zellen oder deren Visualisierung mittels Magnetreso- nanztomographie (MRT) oder Magnetpartikelbildgebung (MPI). Goldnanopartikel erlauben die Visualisierung von Zellen durch weitere unterschiedliche Methoden (MRT, Computerto- mographie (CT), Photoakustische Bildgebung (PAI), Plasmonen-Resonanz). Sowohl Eisenoxid- als auch Goldnanopartikel sind biokompatibel, in einfachen Syntheseverfahren herstellbar und ermöglichen die Bindung von Liganden, um sie mit weiteren Funktionen auszustatten. Durch die Beladung von Monozyten mit Eisenoxid- bzw. Goldnanopartikeln könnte beispielsweise deren Wanderung zu Entzündungsherden durch geeignete Bildgebungsverfahren verfolgt werden bzw. die Zellen magnetisch gezielt an den jeweiligen Wirkort gezogen werden. Ziel dieser Arbeit war es, zum einen die Beladung von Monozyten mit Eisenoxid- oder Goldnanopartikeln hinsichtlich Beladungsmenge und Auswirkungen auf die Zellvitalität hin zu untersuchen. Zum anderen wurde die magnetische Anreicherung der Zellen in einem statischen Magnetfeld untersucht und computergestützt simuliert.

Devising a method for designing multicomponent diffusers of compressors in turbogenerators with hydrogen cooling This study's object is the aerodynamic characteristics of the compressor diffusers in hydrogen-cooled turbogenerators. This paper reports a solution to the task of improving the efficiency of a cooling system discharge unit. This issue relates to enabling the necessary gas consumption while reducing the number of diffuser blades. The problem was solved by introducing a seal with improved technological control capabilities and step-by-step optimization of the diffuser flow part. Another issue is the thermal loads on the power components of the diffuser unit due to the action of circulating currents and temperature gradients. The problem was solved by introducing dielectric and non-magnetic elements into the structure, by additional finning and multi-component design for the diffuser strength circuits. The main result is the designed multi-component diffuser structure with a number of blades of 20 while enabling a head of Hst = 978 mm H2O. The adopted duct opening angle was 20°. Other necessary geometric parameters were determined. The introduction of a multilayer seal made it possible to reduce the gap between the impeller and the diffuser to 0.9 mm. The proposed design was tested on the bench at a manufacturing enterprise. The results of the study are attributed to the use of non-magnetic and dielectric materials (AISI 321 steel and fiberglass), as well as the introduction of additional strength decoupling elements. A special feature of the proposed method is the application of mathematical models based on the basic equations of gas dynamics, taking into account the composition principles of engineering alloys and synthetic materials. This could be achieved via a step-by-step optimization of the design. The proposed structure could be implemented when designing and modernizing hydrogen-cooled turbogenerators Gas compressor ; Computer science ; Process engineering ; Hydrogen ; Nuclear engineering ; Environmental science ; Engineering ; Mechanical engineering ; Chemistry Material Properties and Applications ; Engineering Diagnostics and Reliability ; Advanced Power Generation Technologies

Atomic Absorption Spectrophotometry-Based Evaluation of Iron and Chromium in Community Water Sources Purpose of the study: To determine the presence of heavy metal content, especially iron (Fe) and chromium (Cr) in artesian water wells and residents in Rejo Sari Village.. Methodology: In determining pH, pH meter and universal indicator paper were used. The pH values ​​obtained were 6.5; 6.4; 5.9; 7.4; 6.5 and 7.5. Determination of iron (Fe) and chromium (Cr) content was carried out using the Atomic Absorption Spectrophotometry (AAS) method. Main Findings: The results of the study showed that the concentrations of iron (Fe) were 1.9615 ppm, 0.4692 ppm, 0.4692 ppm, 0.4461 ppm, 1.5615 ppm, and 0.2769 ppm, respectively. One sample with chromium (Cr) concentration was detected at 0.06 ppm. Novelty/Originality of this study: This study presents a novel contribution by comparing the heavy metals Fe and Cr content in two types of well water sources—artesian wells and ring wells—specifically in a densely populated residential area, using an AAS-based quantitative analysis approach rarely applied simultaneously to both metals in a local context. This study also emphasizes the significance of spatial and environmental quality on heavy metal contamination, which has not been widely addressed in similar studies in the region.
