Relevance. A mathematical model of the distribution of the leaf area of a cucumber plant has been developed. On this basis, it is possible to determine the area of the leaf surface of the plant without removing them from the plants. By measuring the minimum number of parameters: the length and width of the largest leaf and the number of leaves on the plant.Methods. We determined the area by two methods: using scales and by scanning the leaves in black-and-white image mode. We present here a step-by-step instruction on determining the area of the sheet in both cases: by weighing and by using graphic editor (program) for his scan file. The accuracy of determining the area is ± 2%.Results. We have developed and practically tested a system for mass determination of the area of cucumber leaves. It includes the development of a mathematical model of the distribution of leaf area by plants at the time of accounting. For practical use of the obtained formulas, it is enough to measure only three parameters on each plant: the number of leaves, the length and width of the largest typical leaf. A typicality criterion based on the ratio of the length and width of the sheet was proposed. The model coincides with the actual plant area with a typical distribution of ±5%. This allows two people to account for up to 500 plants in one working day. The proportion of plants with a typical leaf area distribution ranges from 90% at the beginning of the growing season to 80-85% at its end. This allows relatively accurate calculation of the total area in agrotechnical experiments at minimal cost. The leaves of the plant do not receive any impact and continue to grow at the same time.Conclusion. The developed method allows taking into account the area on the same plants repeatedly, at different phases of ontogenesis and in different periods of vegetation.

In the context of global energy instability caused by the transformation of global demand for energy and energy resources, one of the most important areas in the automotive industry is the development of electric vehicles. Serial production of high-tech electric vehicles with a long range contributes to the stabilization of the energy market and the sustainable development of the whole fuel-energy sector. To evaluate the possibility of optimizing the electric vehicles energy consumption, various regenerative braking strategies are discussed in the article based on the Nissan Leaf electric vehicle, which simulation model includes submodules of the traction electric motor, hybrid braking system, traction rechargeable battery and tires. In order to test the adequacy of the simulation model to reproduce the relationship between the operating parameters of electric vehicles various systems and evaluate their ability to regenerate energy during braking the simulation results were compared with the actual experimental data published by the Lab Avt research laboratory (USA). The relative error of the mathematical modeling results of the braking energy regeneration processes is 4.5 %, which indicates the adequacy of the electric vehicle simulation model and the possibility of its using as a base for research and comparison of the energy efficiency of various regenerative braking strategies. As the results of experiments have shown, the usage of the proposed control strategy of the regenerative braking maximum force allows increasing 2.14 times the energy recharging traffic to the battery as compared with the basic control strategy of fixed coefficient braking forces distribution with an increase in braking distance by 10 m. An alternative control strategy of regenerative braking optimal efficiency as compared to the basic control strategy provides a reduction in braking distance by 13.2 % at increasing by 84.4 % the amount of energy generated by the electric motor for recharging the batteries. The carried out investigations confirm the available significant potential for improving the efficiency of the electric vehicles usage by developing the control strategy and algorithms of the braking energy regeneration.

Measuring devices and systems containing sensors that require sinusoidal excitation are widely used in information and measurement technology both in production conditions and in research practice. Examples include various types of metal detectors, eddy current flaw detectors, analyzers of liquid media, electrometers with a dynamic capacitor, etc. The aim of the work was to develop the optimal architecture and algorithms for the operation of intelligent sensors intended for use in measuring systems operating according to the sinusoidal excitation – response scheme.This paper describes the approach proposed by the authors to the construction of intelligent sensors based on modern microcontrollers, the distinctive feature of which is the continuous generation of sinusoidal excitation and reading responses in the background, as well as setting the readiness flags for data processing in the main process of the microprocessor, which ensures uninterrupted execution of background processes, the main of which is the generation of a sinusoidal excitatory action.This approach has been tested in the development of charge-sensitive surface mapping systems, such as the Kelvin probe based on a vibrating capacitor, and the surface photo voltage probe for the case of semiconductors.

At present time widespread use of autonomous laser systems supposes reducing of supply energy, consumed by laser sources that are included in their composition and at the same time increasing of their output energy characteristics. The objective of this work was practical confirmation of possibility of laser beam combining in systems based on a ring delay line.The experimental setup that implements the principle of synchronous laser beam combining scheme on the ring fiber-optic delay line, developed by authors earlier, is made. The schematic diagram of the manufactured setup is presented, its operation principle is described in detail and its composition is considered. It is noted that in order to achieve the objective measurements of electrical signals received from the photodetector of the setup and measurements of the part of laser radiation power removed by the splitter and formed in the fiber-optic path of the setup are performed. Results of measurements are presented as the waveforms of electrical signals from the photodetector and of power values at the output of the splitter. Plots of dependence of the output power and the circulation power on the power of the initial laser beam introduced into the setup are presented.Analysis of results showed that the laser beam combining occurs in the ring fiber-optic delay line. Besides, it was found that the proposed scheme provides an increase in the power of the initial beam by 1.05…1.11 times.

Study of the Earth’s surface objects reflectance characteristics with unmanned aerial vehicles is one of the most actual remote sensing trends. Aim of this work was to develop a method for obtaining of photospectral data using unmanned aerial spectrometry vehicle.An adaptation of the cameras spatial resolution evaluating technique based on a specialized target photographic fixation was proposed. A method for synchronizing of the camera and spectrometer of the videospectral device was also proposed. It was based on an experiment with spectra and screen images recording. Different colors were sequentially displayed on the screen. The percentage contribution of each of colors to the “mixed” spectra was calculated. So the out-of-sync time estimation became possible. In addition the work proposed the method for combining images and spectra with their merging into photospectral images. The method allows to consider the aircraft displacement when linking the spectrometer field of view to the RGB image. The way for photospectral images combining based on the images key points detectors was also proposed.Spatial resolutions for 3 aerial vehicle cameras were obtained. The study showed that the spatial resolution decrease of Zenmuse H20T caused by the device carrier movement with a speed of up to 5 m/s can be ignored. The videospectral device camera and spectrometer out-of-sync time was evaluated. An automatic merging of a set of images using key points detection was made. The spectrometry areas were linked to the panoramic image. The reflectance coefficients were obtained for each of the areas in the range of 350–900 nm. The areas to image linking accuracy was 84.9 ± 11.6 %.A discrepancy between the angular spatial resolution values got experimentally and theoretically was revealed as a result of the cameras spatial resolution evaluating. This indicates the importance of the imaging equipment spatial resolution experimental evaluation. The videospectral device spectrometer and observation camera out-of-sync time evaluation made it possible to correct the data recording time. This led to the timing error standard deviation reduction from 142 ms to 15 ms. The way for the unmanned aerial spectrometry vehicle data obtaining in a photospectral representation was developed. The proposed methods and techniques can be used in similar unmanned systems.

Published: April 2023

Abstract
Background
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and has a well-established association with coronary artery bypass graft (CABG) surgery. Being able to predict post-operative atrial fibrillation (POAF) may improve surgical outcomes. This study aims to understand the efficacy of incorporating intraoperative medication data to predict first-time POAF in patients undergoing CABG surgery.
Methods
This study aims to understand the efficacy of incorporating intraoperative medication data to predict first-time POAF in patients undergoing CABG surgery. A large cohort of 3807 first-time CABG patients with no known history of atrial fibrillation was retrospectively assembled to study factors that contribute to occurrence of post-operative atrial fibrillation, in addition to testing models that may predict its incidence. To do so, several clinical features with established relevance to POAF were extracted from the electronic health record, along with a record of medications administered intra-operatively. Tests of performance with logistic regression, decision tree, and neural network predictive models showed slight improvements when incorporating medication information.
Results
Analysis of the collected set of clinical and medications data indicate that there may be effects contributing to POAF incidence captured in the medication administration records. However, a definitive causal relationship between the medications and POAF incidence is not established.
Conclusions
Our results show that improved predictive performance is achievable by incorporating a record of medications administered intra-operatively, but further investigation is needed to understand the implications of this for clinical practice.

Abstract

Single-crystal (SC) nickel-based superalloy castings offer high-temperature microstructural stability and superior
creep resistance, due to which they are exclusively used in the hot sections of gas turbine engines. However, SC
nickel-base superalloy components are difficult-to-cut while manufacturing. Worldwide research shows an
interest in improving the machinability of superalloys. The present work is investigating the controlled surface
damage on CMSX-4 superalloy through laser surface remelting technique towards the improvement of
machinability. The specimens were laser-treated using a constant laser power and scan speed and varying the
positive focal position to get a range of energy densities. The process, structure, and property were systematically
studied in the fusion zone (FZ). The FZ shape changed from keyhole to conduction mode with the increasing focal
position. The FZ showed a finer assorted dendritic structure and lesser elemental segregation than the base metal
(BM). In keyhole mode penetration, large pores, and multi-directional cracks were observed in the base region.
On the other hand, the conductive mode showed only vertical centreline cracks and no significant porosity. The
cracks are attributed to thermal stresses and elemental segregation produced during solidification. Microcracking
was also observed near the fusion boundary and is attributed to the presence of low melting Mo and Ti-rich
eutectics. The FZ away from the cracks showed 10% lower hardness than the BM, which is attributed to the
dissolution of 𝛾' phase. Overall, the laser processing under the given range of energy densities produced wide
variants of surface defects in the FZ.

Abstract
Dermatophytes and other members of Onygenales are unique in their ability to degrade keratin, affecting hair and nails, and in case of human hosts cause infection of the skin. Subtillisins are essential proteases in keratin assimilation, and subtilisin-like protease 1 (SUB1) and SUB3–7 are specific for dermatophytes. eIF2α kinases are serine-threonine kinases that perform essential functions in response to infection, proteotoxicity, and nutrient scavenging. The relatively conserved nature of EIF2AK4 among fungi makes them potential evolutionary markers, which may contribute to a deeper understanding of dermatophyte taxonomy and evolution. The aim of the present study was to evaluate the phylogeny of dermatophytes using EIF2AK4 and SUB1 genes, compared to ITS evolution. The EIF2AK4 tree had a similar topology to the SUB1 tree, and both deviated from the ITS gold standard by evolution. Our preliminary findings with a limited dataset suggest that the EIF2AK4 and SUB1 genes provide a reasonably correct reflection of the evolution of Arthrodermataceae. In addition, the study analyzed in vitro keratinolytic responses of 19 dermatophyte species using hairs of a broad selection of mammals as substrates. Trichophyton mentagrophytes and Nannizzia gypsea were the most active in degrading hair, while Trichophyton verrucosum, Trichophyton tonsurans and Epidermophyton floccosum showed low response. Hairs of Hyracoidea and Rodentia were most affected of all mammal hairs, while in contrast, bat hairs were difficult to degrade by nearly all tested dermatophyte species. Zoophilic species showed more activity than anthropophilic dermatophytes, but hair degradation profiles were not diagnostic for particular dermatophyte species.

Abstract
Background: Culture-compatible interventions are important for the success of mental health programs in different communities. The Thinking Healthy Program (THP) proposed by WHO is an evidence-based intervention for the treatment of prenatal depression that requires adaptation in any country or culture.
Methods: The THP was translated in two copies by two translators of Iranian origin with academic education in English. A panel of experts was held to perform content and face validations. A systematic review was conducted, the strategies of the program were presented using nominal group technique, and a pre-test was performed. Finally, both the mothers and peers were asked for their opinions through open-ended questions.
Results: Some terms were changed and some images were modified. Sexual health content and a training session about natural childbirth were added. Most of the mothers and peers considered the program acceptable and understandable and the images appropriate, and suggested expanding the program to all health care centers.
Conclusion: The Persian version of the THP seems to have adequate validity to be used in Iran.
