Published: July 2023

Lung vital capacity of is different for each individual depending on personal characteristics, such as age, body mass index (BMI), and exercise habits or environmental factors, such as exposure to cigarette smoke. This study aimed to determine the relationship between personal characteristics, duration of exposure to cigarette smoke, and lung vital capacity in passive smokers in one of the areas in Indonesia. This study was a cross-sectional observational analytic study conducted during the period of August to September 2019. Data were collected through interviews and measurements using the Contec SP10BT spirometer. Participants were sampled consecutively with only women who did not smoke but had at least one family member who actively smoked and was over 20 years old participated in this study. Women were selected as the population due to the fact that the proportion of passive smokers among women is higher than men, while the age group of above 20 years old was selected with a consideration of the average age for the optimum lung capacity. The relationship between personal characteristics and a history of exposure to cigarette smoke with lung vital capacity was analyzed using Pearson and Spearman correlation test. There is a significant relationship between age, exercise habits, duration of exposure to cigarette smoke, and vital lung capacity (p=0.000; p=0.018; p=0.000) among the participants of the study. However, further research is still needed to be able to generalize this finding into a broader community.

Published: July 2023

Each coil of copper produces a magnetic field and the total field inside the solenoid will be the sum of the fields caused by each coil of current. If the solenoid coils are very closely spaced, the internal field will be essentially parallel to the axis except at the very ends. To find out the magnitude of the magnetic field inside the solenoid, you can use Ampere’s law, namely B=μo∙N∙I, where B is the magnetic field strength (T), µo is air permeability (4×10‒7 T m/A), N is the number of turns and I is an electric current. The value of B depends on the number of turns per unit length, N, and current I. The field is independent of the position inside the solenoid, so the value of B is uniform. This only applies to infinite solenoids, but is a good approximation for actual points that are not near the ends of the solenoid.
The research object is 4 identical copper coils with a length of 3 cm, a coil diameter of 2 cm, a cross section of 1.5 mm2 with an inductance value of 2.17 µH. Before coating curcumin on the copper winding, the initial value of the magnetic field strength was 2.54 µTesla. After the coating process of curcumin:H2O concentration, the value of the magnetic field strength increased.
The method used was immersing 4 copper coils with an inductance value of 2.17 µH in curcumin:H2O concentration in a 100 ml volume measuring cup, with the respective concentrations: (20 %:80 %), (40 %:60 %), (60 %:40 %), (80 %:20 %) in a certain time. Then the copper coil conductor is supplied with a 5-volt DC voltage source. Then the value of the magnetic field strength (B) and electric current is measured, the results are compared with the system before immersing the copper coil.
The measurement results showed that the values of electric current and magnetic field strength increased after curcumin coating compared to before treatment. To see the bonding performance of curcumin and copper, the FTIR test and simulation of the curcumin: copper bond were carried out using Avogadro software. In the IR test, there is a strong absorption of aromatic C-C from 1,650 cm-1 to 1,500 cm-1. Whereas in the simulation, the bond between copper and curcumin produces a bond energy of 164.532 kJ/mol or equivalent to 171.12×10-2 eV

The object of this study is the aperture brightness of the image of the object, which has a variety of typical shapes in the frames of the series. It directly depends on the stability of the shooting conditions of the objects under study. Thus, determining the exact aperture brightness of an object in the frame becomes more difficult. For this purpose, a method was devised for determining the aperture brightness of an object using the typical shape of its image on a series of frames.
This method is based on the formation of a typical shape of a digital image of an object based on data from all frames of the series. The typical shape makes it possible to take into account the peculiarities of the formation of the image of the object on each frame of the series. Based on this, a more accurate estimate of the initial approximation of the parameters of all Gaussian images of the object is performed. In addition, the adaptation of the method to the standard shape makes it possible to perform a more accurate assessment of the aperture brightness of the object in comparison with the analytically defined profile. An estimate of the aperture brightness of the object was derived using the least squares method. Due to minimization using the Levenberg-Marquardt algorithm, the use of the method improved identification with reference objects and reduced the number of false positives. The study showed a decrease in the standard deviation of frame identification errors by 5–7 times when using a typical shape of a digital image.
The devised method for determining an object's aperture brightness using its image's typical shape was tested in practice within the framework of the CoLiTec project. It was implemented in the intra-frame processing unit of the CoLiTecVS software for the automated construction of brilliance curves of the studied variable stars. Owing to the use of the CoLiTecVS software and the proposed computational method implemented in it, more than 700,000 measurements of various objects under study were successfully processed and identified

This work used soursop as a green corrosion inhibitor to protect API 5L Grade A from detrimental corrodent under produced water. Despite the effectiveness of inorganic inhibitors, recent evidence on their toxicity test suggests that implementing organic inhibitors is substantial to replace synthetic corrosion inhibitors. However, soursop utilization as a green corrosion inhibitor is poorly understood due to the lack of a comprehensive extraction mode and inhibitive mechanism. Several tests were conducted, including weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS), to unveil the nature of corrosion inhibition. Fourier Transform Infra-Red Spectroscopy revealed the dominant functional groups to bind with the substrate. The potentiodynamic polarization results show that the inhibitor is a mixed-type inhibitor that influences the anodic and cathodic reactions. The weight loss test showcases the highest inhibition efficiency of 52.62 % upon adding 2 ml inhibitors upon eight observation days. The polarization and EIS results provide that the inhibitor reduces the corrosion rate with higher inhibition of 88.52 %. The mentioned result is associated with the attachment of non-polar and polar Annona muricata Linn functional groups. The primary functional group involves C=O, C‒C and –O.H., which actively bonded to the metal's surface. The aromatic group at a wavenumber of 1,050 and 1,090 cm-1 shows ether's presence and behaves as an adsorption center. In this work, combining three solvents, hexane, acetone, and ethanol, elicits the complete extraction of the predominant compound from soursop

Published: July 2023

The subject of this study is the quality indicators (geometric accuracy, roughness, cylindricity and taperness) of holes obtained by drilling in aircraft structures (AS) made of polymeric composite materials (PCM). The quality indicators of holes in AS made from PCM were studied by using kinematic schemes across and along the direction of drilling. A kinematic scheme of formation of the predicted surface roughness of the hole in AS made from PCM has been built. The calculation of the predicted roughness of PCM holes taking into account the geometry of the drill and drilling modes has been proposed. Experimental studies have been implemented to establish the parameters of predicted roughness, geometric accuracy, taperness, as well as deviations from cylindricity. The methods used were the method of expert assessments and experimental studies of quality indicators of PCM openings. The following results were obtained: the roughness in full-scale experiments turned out to be lower than the theoretical calculated values with a difference of not more than 10...15 %. It was found that roughness, taperness, deviations from geometric precision and cylindricity differ in characteristic rotation zones of the drill from 0° to 360° and depend on the drilling parameters and PCM properties. It was found that the deviation from the hole cylindricity is affected by the shrinkage of the material. The appearance of ovality in the holes of prototypes was established. The results of experimental studies of measurements of hole diameters to establish deviations from cylindricity, geometric accuracy, and taperness met the production requirements for the accuracy of their manufacture. For geometric precision and deviation from cylindricity, the results ranged from 7 to 12 IT grades, and for taperness, from 0.083 to 0.28 % per a hole in AS made from PCM and 9–10 IT grades

The object of the study are the fruits of cucurbits crops, as well as confectionery products based on the fruits of watermelons and melons. The fruits of watermelons and melons are not processed on an industrial scale for a number of reasons: the lack of technological solutions for primary processing and preparation for processing, the instability of raw materials for processing. The pulp of watermelons must be processed within 5 hours under certain conditions; in the pulp of melons, changes in microbiological indicators begin within an hour of storage at room conditions. Because fruits have a high moisture content, the solution for effective fruit processing is to bind this moisture with thickeners and produce jelly candies. Sweets made without antioxidants did not withstand the standard shelf life for jelly sweets, and the growth of mold fungi increased. The reason may be the low acidity of the raw material. Citric acid was added as an antioxidant. There were problems of taste and smell; citric acid interrupts the natural smell of raw materials. During the search, the powder of dried, red-fruited rowan was chosen. The finished product had a barely perceptible natural aroma, the powder did not affect the taste. There were inclusions in the cross-section, but the appearance became more attractive.
Jelly sweets without the addition of rowan powder had active mold growth on the 7th day of storage at a temperature of 22–25 °C; with the addition of rowan powder under the same storage conditions, they showed growth on the 16th day.
The finished product meets all physical, chemical, and microbiological standards. The shelf life of such jelly sweets at a temperature of +6 °C in sealed packaging is up to 30 days without mold formation
Devising a method for detecting “evil twin” attacks on IEEE 802.11 networks (Wi-Fi) with KNN classification model

Published: July 2023

The object of research is IEEE 802.11 (Wi-Fi) networks, which are often the targets of a group of attacks called "evil twin". Research into this area is extremely important because Wi-Fi technology is a very common method of connecting to a network and is usually the first target of cybercriminals when they attack businesses. With the help of a systematic analysis of the literature focused on countering attacks of the "evil twin" type, this work identifies the main advantages of using artificial intelligence systems in the analysis of network data and identification of intrusions in Wi-Fi networks. To evaluate the effectiveness of intrusion detection and cybercrime analysis, a number of experiments as close as possible to real attacks on Wi-Fi networks were conducted.
As part of the research reported in this paper, a method is proposed for detecting cybercrimes in IEEE 802.11 (Wi-Fi) wireless networks using artificial intelligence, namely a model built on the basis of the k-nearest neighbors method. This method is based on the classification of previously collected data, namely the signal strength from the access point, and then continuous comparison of the newly collected data with the trained model.
A compact and energy-efficient prototype of a hardware and software system has been designed for the implementation of monitoring, analysis of ethernet network packets and data storage based on time series. In order to reduce the load on the computer network and taking into account the limited computing power of the system, a method of data aggregation was proposed, which ensures fast transfer of information.
The results, namely 100 % of test cases (more than 7 thousand), were classified correctly, which indicates that the chosen method of data analysis will significantly increase the security of information and communication systems at the state and private levels

Published: July 2023

The flammability of wood largely limits the use of wooden structures in modern construction. Therefore, there is a need to protect the wooden structures of buildings and structures from fire danger.
Ammophos-A, ammonium sulfate, expanded perliteб and epoxy were used to develop the fire-retardant surface coating. The experiments were carried out by changing the amount of one of these components in the composition, leaving the others constant. At the same time, fire hazard indicators were controlled parameters. In this way, the optimal ratios of the components of the flame-retardant composition were established, which were: 15:15:10:50 (wt.%), respectively, ammophos-A, ammonium sulfate, expanded perlite, epoxy resin, further designated flame retardant AS-143. The test parameters of structural samples treated with this flame retardant at a consumption of 400–500 g/m2 were: weight loss 4.0–5.0 %, flame burning time 11–18 s, flameless 19–23 s. The effectiveness of the flame retardant AS-143 was established in comparison with flame retardant No. 13, which, according to the weight loss of the samples, was 43.2 %.
The essence of the results is explained by the correct selection of chemical compounds and their component ratio in the fire-retardant composition, which exhibit a synergistic character during the combustion of wooden structures.
At the next stage, in addition to surface treatment of wooden structures, they were faced with fire-resistant plasterboard sheets. Fire tests were carried out under field conditions for 30 minutes, the results of which were: the length of flame propagation over the surface of the samples was 456–678 mm; flame propagation speed 0.015–0.023 m/min.
The data indicate that wooden structures treated in a combined way belong to group I of fire protection efficiency. These structures can be safely used in buildings and structures, especially with enclosing, attic, or attic types

Multiwell Fiber Optic Sensing Reveals Effects of CO2 Flow on Triggered Seismicity

Abstract
Induced seismicity is one of the main risks for gigaton-scale geological storage of carbon dioxide (CO2). Thus, passive seismic monitoring is often recommended as a necessary component of the monitoring systems for CO2 storage projects, with a particular forcus on risk mitigation. We present the first field study, CO2CRC Otway Project Stage 3 (Victoria, Australia), where distributed acoustic sensing (DAS) enabled high-precision tracking of the induced seismicity triggered by a small CO2 injection and also informed the reservoir models. In 610 days of passive seismic monitoring of the Stage 3 injection, we detected 17 microseismic events (maximum moment magnitude Mw 0.1) using five deep boreholes equipped with enhanced-sensitivity optical fiber. The DAS array has sensitivity sufficient for detection and location of induced events with Mw∼−2 in a monitoring borehole located up to 1500 m away. Thanks to the dense spatial sampling by the DAS, we were able to estimate the focal mechanisms for events with Mw&gt;−1.5; although the monitoring boreholes provided very limited angular coverage. The main cluster of the events has the same location and source mechanism as the one triggered by the previous CO2 injection at the Otway Project site, Stage 2C. Surprizingly, the Stage 2C and Stage 3 events closely followed the actual movement of the CO2 saturation plume front (not the pressure front), as observed using controlled-source reflection seismic images. The nature of the plume-fault interaction remains unclear, but some alteration of the fault gouge by CO2 might be responsible for the faults’ reactivation by the pressure perturbation. Importantly, the seismogenic fault could not be identified in the seismic images and was only revealed by DAS observations, which also demonstrated the signature of fluid–rock interaction, that may control the CO2 flow.
