: The measurements for assessing the antero-posterior discrepancy between the apical bases are many with their individual benefits and shortcomings. So, it is very important to categorize the reliability of the major diagnostic criteria for successful planning of treatment and to fore see the outcome. The present study assesses the predictability of Wits appraisal, ANB, Beta, Yen, W, µ and Pi angles as an indicators of anteroposterior dysplasia. A total of 120 lateral cephalograms of skeletal Class I, II and III patients were selected based on Down’s facial angle and then tracing was carried out manually to measure Wits appraisal, ANB, Beta, Yen, W, µ and Pi angles. Analysis of variance and correlation coefficient analysis were done to assess the significance of association between these variables. Yen angle is highly predictable and a homogenously distributed angular parameter used to assess sagittal discrepancy. The most desirable differentiation results among the three skeletal relationship were represented by Beta angle followed by Yen angle. Statistically significant correlation among the seven parameters for skeletal Class I relationship were shown by Yen and W angle, for skeletal Class II relationship by Beta angle and µ angle and for skeletal Class III relationship by Beta angle and W angle. No statistically significant correlation existed between Yen Angle and Beta Angle in all the three groups. Yen angle was found to have the most homogenous and predictable parameter. A statistically significant correlation for skeletal Class I relationship were observed between Yen and W angle, for skeletal Class II relationship between Beta and µ angle and for skeletal Class III relationship between Beta angle and W angle and they can be used interchangeably in assessing skeletal jaw relationship.

The aim of the study is to highlight the common difficulties faced and experiences of the patients while undergoing fixed orthodontic treatment, along with their oral hygiene practices and perception of the treatment. The study was conducted to survey the patients undergoing fixed orthodontic treatment using an online questionnaire via Google forms, with four sections. An informed consent was taken from the patients. The questionnaire was divided into 4 sections.Section 1: Demographic details and Informed consentSection 2: Difficulties and Experience of the patient during Orthodontic treatmentSection 3: Oral Hygiene Practices during Orthodontic treatmentSection 4: Patient’s perception of the treatment The most common difficulty found to be faced by the patients undergoing fixed orthodontic treatment is pain due to activation of wire after an orthodontic appointment (63.5%), followed by ulcers on cheeks/lips (44.3%) and swollen gums (30.5%). It was also found that majority of participants (79.8%) used an orthodontic toothbrush and 66% of them brushed twice daily to maintain their oral hygiene. As per patient’s perception, 61.6% of participants were bothered by longer duration of the treatment. The study concluded that patients undergoing fixed orthodontic treatment face a number of difficulties. Although pain due to wire activation was the most often reported issue, quite few participants sought any medication for pain alleviation, suggesting that the pain was not particularly intense. The majority of participants used an orthodontic brush, while only a few used floss to maintain oral hygiene. Around half of the total participants were conscious of their appearance due to visible braces.

Published: June 2023

The purpose of the publication is to develop a methodology for presenting the unit "6 kV compressor-synchronous electric motor" in the form of a finite state machine.
It is hypothesized that the behavior of the compressor unit can be associated with the behavior of an abstract deterministic finite state machine.
The theory of finite state machines and graphs is applied to analyze the operation of a compressor installation using the example of a compressor of a large-tonnage shop for the production of ammonia. It is shown that the theory of finite state machines allows combining all possible modes of operation and shutdown of compressor units. Coding of reasons for compressor shutdown due to problems in the electrical or mechanical parts of the compressor unit is proposed. A diagram of state transitions has been developed for it. Such a diagram can be useful for compiling a concise description and understanding of the operation of a compressor unit, advanced training of technological personnel during industrial training, for emergency training, etc.
A graphical analysis of the obtained diagram was carried out. The optimal (most perceived in terms of energy efficiency) route of the graph is determined.
The proposed form of abbreviated recording of the compressor operation cycle and the electronic mileage log, which allows you to calculate the remaining resource of the compressor installation and the compressor operation time.
The implemented methods make it possible to identify bottlenecks in the complex electrical and technological equipment of industrial enterprises.

Published: June 2023

This article studies the future development of the energy industry with the aim of reducing greenhouse gas emissions. Three different options for planning the use of electricity-generating enterprises and determining the most optimal for the environment and economy of the country based on graphs of the dynamics of greenhouse gas emissions into the atmosphere are considered. The assessment and selection of the most optimal option is based on the Low-Carbon Development Strategy of Ukraine.
The types of electricity generation that most pollute the environment and those that practically do not pollute have been determined. The share of produced electricity accounted for by each type of generation and the dynamics of electricity production in recent years were considered in percentage terms. Also, this article provides an example of one of the countries abandoning nuclear energy, and what consequences this had for the energy balance and the development of a low-carbon economy. The most appropriate option for the development of power plants in Ukraine was determined and it was considered how in the future it is possible to increase the share of electricity produced at nuclear power plants and reduce the share of electricity produced at thermal power plants. The development of nuclear energy has a positive effect on the country's energy independence, so it must be developed and, if possible, switched to new types of reactors in order to make energy even more secure.
RESEARCH OF VALVE MOTOR CONVERTER CONTROL METHODS
Authors: Zakladnyi Oleg , Prokopenko Volodymyr 
Published: June 2023

A technique for selecting the electrical equipment of a valve motor with machine commutation has been developed, which takes into account the ways of controlling the inverter. The installed capacity of the electrical equipment of the valve motor (VD) is determined by technological requirements and depends on the structure of the converter, the method of commutation of the converter keys and the methods of controlling the inverter. The use of autonomous inverters with artificial switching, the keys of which are switched due to the reactive energy accumulated in additional switching devices, increases the utilization factor of the synchronous machine. However, in this case, the circuit becomes more complicated and the installed power of the converter increases. The use of IGBT transistors and IGCT thyristors leads to a significant increase in the cost of the equipment.
To reduce the influence of the rectifier VD on the network and match the drive voltage with the supply voltage, a matching transformer and reactive power compensation device may be needed. The amount of power of this equipment is affected by the method of controlling the rectifier, the nature of the engine load and the range of speed changes.
Voltage regulation of the rectifier can be symmetrical or asymmetrical. Several methods of asymmetric regulation are known, among which one of the most expedient is alternating. In the case of alternating control in the three-phase bridge circuit, an artificial zero circuit is created, as a result of which the duration of the current flowing through the secondary windings of the transformer becomes less than 2/3 of the half-cycle of the supply voltage. In addition, the energy indicators also increase, in particular, the reactive power consumption decreases and the shift and power coefficients increase.

Published: June 2023

Purpose. The goal of the article is to develop a method for identifying hazards and predicting the possibility of a technogenic emergency caused by the spread of compounds with heavy metals in the soil during long-term storage of galvanic sludge in open areas.
Methodology. The method is developed on the basis of a mathematical model that allows estimating changes in the depth of distribution and level of soil salinity over time using initial information about soil structure and its characteristics (molecular diffusion coefficient, volume humidity), annual volumes and conditions of sludge storage in the enterprise. Restrictions are set: the presence of harmful substances on the soil surface with a concentration that exceeds the permissible level; inadmissibility of harmful substances to aquifers.
Results. The practical use of the method made it possible to identify the main dangers and predict the possibility of an emergency situation with negative environmental consequences during long-term storage of galvanic waste in open areas. The dynamics of soil salinity levels and the depth of penetration of heavy metals increase over twenty years of conservation has been determined, as well as the possibility of hazardous compounds entering groundwater has been assessed.
Originality. The non-linear, non-stationary mathematical model is based on the theory of physico-chemical hydrodynamics of cellular media. The process of motion of metal salts has been described by the differential equation of motion and conservation of mass of matter for vertical mass transfer of matter.
Practical value. Formalization of information about the hazards arising during the storage of industrial waste with chemically active elements allows to consider the subject area as a complex dynamic system consisting of objects of different nature, the totality of which determines the level of danger of emergencies with environmental consequences. The developed method makes it possible to transfer the obtained results to decision-making support systems, predicting possible consequences and material costs associated with post-emergency measures, motivating the management to take measures in advance.

A new approach for DVHOP localization algorithm improvement in Wireless Sensor Network
Authors: Arroub Omar , Darif Anouar , Saadane Rachid , Rahmani My Driss , Aarab Zineb 
Published: June 2023

Wireless sensor networks (WSN) are mostly utilized in many applications. Indeed, WSN is composed of sensors to evaluate some physical phenomena. However, the information brought by the sensor still missed if we don&#039;t know the exact location of the event. Several localization algorithms have been proposed in order to locate the nodes in WSN. The localization algorithms are categorized into range-based and range-free techniques. The range-based techniques use either distance or time to calculate the coordinates of unknown nodes. Nevertheless, those kinds of techniques need some additional material in computation purpose. Therefore, range-based techniques present an expensive solution for positioning in WSN. Alternatively, range-free techniques may do the same task without involving additional material. But they don’t offer a high precision of localization in comparison with range-based techniques. DVHOP is the most popular range-free technique that uses the hop count method in the localization process. In this work, we propose an improvement of DVHOP localization algorithm to create three improved versions of this algorithm and we have achieved that by adopting two meta-heuristic (simulated annealing, particle swarm optimization) and FMINCON solver dedicated to the optimization in the field of WSN nodes localization. The experimental results obtained in this work show clearly the gain and the good impact of our proposition.

Published: June 2023

Background: This study was planned to determine the dosage and duration of thymoquinone (TQ) at which it demonstrates the optimum effect on the total antioxidant status (TAS) and the biochemical parameters in the blood serum.
Materials and Methods: 48 male rats (Wistar-albino) weighing between 200-250 g were used as material. Group 1 (control) (TQ solution 5 mg/kg/day), Group 2 (15 mg/kg/day), Group 3 (30 mg/kg/day), Group 4 (45 mg/kg/day) and Group 5 (60 mg/kg/day) were designated, each containing 8 rats. Different doses of TQ (oral gavage) were administered for four weeks.
Results: The TAS levels were determined to be considerably low statistically in all TQ-administered groups in comparison with the control group. It was determined that the serum biochemical parameters exerted a significant effect depending on the TQ doses.
Conclusion: As a result, rats administered with TQ orally, at 60 mg/kg dosage, show that the liver and kidney function parameters in particular as different from normal. This brings us to the conclusion that at this dosage, there is reliable biochemical wise but future protective studies in which 30 mg/kg doses can be used safely is encouraged.
