Authors: Hiranya Putri Megananda , Nurjanah Neneng , Herijulianti Eliza , Utami Ulfah
Published: June 2022

Toothbrush contamination occurs immediately after use and increases when use is repeated. After the toothbrush is used, it should be washed and disinfected. Bay leaf (Eugenia polyantha Wight) can be an alternative herbal disinfectant because it contains tannin, flavonoids and essential oils that are antiseptic and antimicrobial. This study was an experimental laboratory to see the inhibitory content of bay leaf extract concentration of 20%, 30%, 40%, 50% and 60% on the growth of toothbrush bacteria colonies. Samples are bacterial colonies originating from 8 toothbrushes that have been used by 8 students in the mass toothbrush activity in SDN Harapan in the City of Bandung, with inclusion criteria aged 9-12 years and having a DMF-T index> 3. Repeat treatment for each concentration was 4 times. The results showed that bay leaf extract at concentrations of 20%, 30%, 40%, 50% and 60% could inhibit the growth of bacterial colonies, but when compared with the antibacterial effects produced by antibiotics Ciprofloxacin (5 µg), inhibitory content of bay leaf extract the five concentrations are relatively smaller. Colonies of contaminant bacteria that often appear on toothbrushes are Neisseria sp and Streptococcus sp, Klebsiella sp, Enterobacteriaceae sp (Coliform), and Staphylococcus aureus. Further research can be developed to find out other herbal ingredients that can be combined to increase disinfection, good dosage forms and the right contact time between disinfectant and toothbrushes.

Authors: ADİN Mehmet Şükrü , İŞCAN Bahattin , BADAY Şehmus
Published: June 2022

Martensitic stainless steel AISI 431 and low carbon steel AISI 1020 are materials used together in many different industries. However, important problems are encountered when welding (fusion welding) these materials to each other. For this reason, friction welding process (Solid-state welding) is used to join these dissimilar metals. There are very few studies on joining these materials with friction welding. Therefore, the optimization of the welding parameters used in joining these dissimilar steel pairs with friction welding is of great important. In addition, the effects of the factors dependent on friction welding parameters need to be well understood. In this study, AISI 431 and AISI 1020 steel bars were successfully joined by friction welding, and the effects of welding parameters on tensile strength and axial shortening were investigated, and welding parameters were optimized using Taguchi method to obtain quality weld joints. The experimental results of the study showed that the highest tensile strength (573.32 MPa) of the joints was 54.53%, higher than the lowest tensile strength (370.99 MPa), the highest axial shortening (23.18 mm) was 650.16%, higher than the lowest axial shortening (3.09 mm). The optimal parameters for average axial shortening and average tensile strength were determined as A3B1C3 and A3B3C2; and the highest percentage contribution values for axial shortening and tensile strength were found to be 51.55% (rotating speed) and 63.90% (rotating speed); and R2 values for the average axial shortening and average tensile strengths were found to be 97% and 99.3%, respectively.

La primera mitad del año, cuando el COVID parecía comenzar a replegarse en el mundo, nos sorprendió el inicio de la guerra de Ucrania, el 24 de febrero de 2020, que al momento de escribir estas líneas, aun no tuvo resolución. El regreso a métodos tradicionales de invasión territorial (con preludio en la apropiación de Crimea en 2014) despertaron alarmas rojas en la seguridad europea y en la relación de Rusia con Estados Unidos y las expectativas respecto a la posición de China y los nuevos equilibrios globales. Asimismo la prolongación del conflicto trajo efectos secundarios no menores, como el aumento de los precios de la energía y alimentos, fertilizantes y minerales raros provenientes de Rusia y Ucrania, afectando las economías que venían de sufrir la retracción por el golpe de la pandemia, principalmente en el caso de los países del Sur

Published: June 2022

Pervious concrete pavement has been used widely as an effective practice for water management in low-impact development techniques. The hydrologic performance of pervious concrete pavement depends significantlyon the rainfall intensity and the designed slope. This study assessed the hydrologic performance of pervious concrete pavement by evaluating the time for surface ponding via finite element analysis. A series of simulations were carried out to explore the relationship between hydrologic performance and pervious concrete pavement by the Hydrus 2D program. The research’s results showed that as the slope increased, the time of surface ponding also increased. The data indicated that the slope variable had a low impact on the water level in pervious concrete pavement under a constant rainfall intensity. Observation of the effect of rainfall intensity showed that when the rainfall intensity increased twofold, the time for surface ponding dropped about two times. Furthermore, when surface ponding appeared, pervious concrete pavement at higher rainfall intensity had lower water content. The rainfall intensity also significantly affects the hydrologicperformance of the pervious concrete pavement. This study only assessed the hydrologic performance by using the time for surface ponding via finite element analysis. Further experimental studies should be conducted to examine the relationship of other factors to the hydrologic performance of pervious concrete pavement.

Published: June 2022

The Arbuscular Mycorrhiza fungi have a mutualistic relationship with 80% of terrestrial plants. Arbuscular Mycorrhiza fungi are considered as a biofertilizer source because of their positive effects on plant growth andproductivity They can help to reduce the amount of chemical fertilizers by up to 50% due to their ability in enhancing crops to uptake mineral nutrients efficently such as nitrogen, phosphorus, potassium, calcium, zinc. . . thereby increasing crop yield. Moreover, this endosymbiotic fungus also shows its potential as a biopesticide due to its ability to biologically antagonize a wide range of fungi, viruses, and nematodes, which cause diseases on plants. Besides, Arbuscular Mycorrhiza fungi also help plants to resist to abiotic streeses such as drought, salinity, and toxicity of heavy metals. The glomalin compound secreted by mycorrhizal fungi has the ability tobind tiny soil particles together to form a stable soil structure and aggregates, helping to improve soil qualitỵ Thus, Arbuscular Mycorrhiza fungi have a high use potential in sustainable agricultural development under the context of climate change such as drought, salinity intrusion.
Bankrobotika: mesterséges intelligencia és gépi tanulás alapú banki kockázatkezelés : Pénzmosás és terrorizmusfinanszírozás megakadályozása
Authors: Prisznyák Alexandra
Published: June 2022

A Pénzügyi Akciócsoport pénzmosással és terrorizmusfinanszírozással összefüggő országvizsgálat alapján leminősítette Magyarország R15-ajánlásnak (új technológiák alkalmazása) való megfelelését. Ezzel párhuzamosan a Magyar Nemzeti Bank 2020–2021 között számos, Magyarországon működő kereskedelmi bank esetében állapított meg bírságot a pénzmosás és terrorizmusfinanszírozás megelőzésével kapcsolatos hiányosságok miatt. A tanulmány hiánypótló elemzésként a banki kockázatkezelés, pénzmosás és terrorizmusfinanszírozás megelőzésért felelős területek nagymértékben kiegyensúlyozatlan adatállományán operáló felügyelt (osztályzás, regresszió), felügyelet nélküli (klaszteranalízis, anomália-észlelés) és hibrid gépi tanulási modelleket, alkalmazott algoritmusokat vizsgálja. A szerző hangsúlyozza, hogy nincs egyetlen ideális algoritmus. A választást a mögöttes működési logika mellett számos összehasonlító tényező támogatja. A modellépítés az üzleti IT- és vizionárius menedzsment hibrid szempontjainak kialakítását igényli.
Formation and Properties of Heterosystems Based on Porous Silicon, Graphitic Carbon Nitride and Semiconductor Compounds
Authors: Grebnev V. P. , Chubenko E. B. , Bondarenko V. P.
Published: June 2022

The possibility of pyrolytic synthesis of composite heterosystems based on macroporous silicon, graphitic carbon nitride and wide band semiconductors zinc oxide and zinc sulfide (g-C3N4/ZnO/ZnS) from a mechanical mixture of thiourea and zinc acetate at 500 – 600 °C was shown. The obtained material study by scanning electron microscopy and energy dispersive X-ray spectroscopy showed a uniform filling of macroporous silicon with the composite g-C3N4/ZnO/ZnS with the formation of a continuous composite film on the surface. The photoluminescence of the samples was controlled by the synthesis temperature. Increase of photoluminescence leads to shift of luminescence maximum in high energy range from 544 to 516 nm. It was found that photocatalytic activity of composite heterosystems obtained at a lower temperature is higher due to more developed surface morphology and smaller bandgap width. The materials obtained can be used to create photocatalytic coatings and functional layers of optoelectronic devices.

Authors: Vishniakou U. А. , Zhifeng Hu
Published: June 2022

The purpose of the article is to analyze methods, approaches and means of Internet of Things (IoT) technology for product quality control. The objectives of the article are: analysis of dairy farm management problems, development of the structure of the IoT network for milk quality analysis, development of an algorithm for the operation of the IoT milk quality control network, optimization of IoT network protocols choice. Two types of management are considered for the functioning of a dairy farm: production and processes. To implement dairy farm management using 4.0 technology, the use of an IoT network is proposed, in which various communication protocols are considered. The structure of the IoT network of four-level dairy farm management is proposed, which includes analyzers, a gateway, a cloud platform and various applications for farmers and operators. A generalized algorithm for milk quality control on a farm based on the developed IoT network structure is presented, which includes receiving information from analyzers, transmitting it through a gateway to a cloud platform for storage and intelligent processing, displaying results through operator applications. The application of intelligent algorithms for farm management is also considered: data processing and training ‒ ML, knowledge processing ‒ DT, security ‒ FL. The process of selecting a suitable network protocol for monitoring a dairy farm is carried out using the hierarchy analysis method, which uses expert estimates corresponding to four network indicators: transmission speed, distance, frequency and security. The formulated approaches can be applied in various production processes to monitor product quality.

Published: June 2022

The effectiveness of biofeedback trainings to develop relaxation skills was investigated using the NeuroDog hardware and software complex. Discriminant analysis (a method of multivariate statistical analysis) was carried out, which made it possible to assess the quality and accuracy of the grouping of drivers and assistant drivers of locomotive crews into groups with varying degrees of successful development of the relaxation skill. Highlighted the most informative signs of dividing drivers into groups. The accuracy of the presented groups was checked using linear qualification functions, the informativeness of the features was assessed by Fisher's F-criterion. The critical level of significance when testing statistical hypotheses is p < 0.05. In the course of discriminant analysis, a number of characteristics necessary for the interpretation of groups and their differences were calculated, such as: linear classification functions, canonical discriminant functions, and factor load of canonical discriminant functions. Informative differential diagnostic signs for diagnostics of locomotive crew drivers for the development of relaxation skills were shown. Formulas of linear qualifying functions are given. The diagnostic accuracy was 84.91 % on average.
