Materials and methods. Four amylopectin varieties Chabanivske, Zhyvynka (NSC Institute of Agriculture) and Osoblyve and Alternatyvne (Institute of Plant Industry named after V.Ya. Yuriev) were taken as experimental material. The main economically valuable characteristics of the varieties and their biochemical properties of grain were made in 2018–-2020. The main technological indicators of the dough and the assessment of the quality of bread from a mixture of spring wheat flour of the Myronivska variety and grain flour of the Chabanivske variety were carried out in accordance with the current methods. Millet flour was added to wheat flour in proportions of 2.5, 5.0, 7.5 and 10.0%.
The purpose of our research was to study the main economically valuable traits, biochemical properties and resistance to 13 smut races of Ukrainian amylopectin varieties of millet and to determine the optimal percentage of adding millet flour to spring wheat flour to improve the quality of bread.
The discussion of the results. According to the results of scientific work, it has been established that millet waxy varieties differ in their economically valuable characteristics. So, varieties Chabanivske and Zhyvynka have a short growing season, on average, 75 and 77 days, respectively, and varieties Osoblyve and Alternatyvne – 93 and 100 days, respectively. Due to the increased height of the plants of the Osoblyve and Alternatyvne varieties, they can also be grown for animal feed. In terms of biochemical parameters, modern amylopectin varieties did not differ significantly, but showed a high content of protein (13.50–14.0%) and carotenoids (4.8–5.6 mg/kg). Amylos-free starch genotypes varied significantly in terms of head smut resistance. Variety Chabanivske was affected by 13 smut races, varieties Alternatyvne and Osoblyve received 8 and 7 points in 1 and 10 races. Variety Zhyvynka showed high resistance to 8 smut races: Rs 1, Rs 4–Rs 7, Rs 9–Rs 11 – 9 points. The addition of flour from amylos-free starch millet improved the elasticity and extensibility of the dough, increased the balance of these physical properties of the dough with each other, improved the strength of the flour, but did not affect the sedimentation rate. Bread baked with the addition of 2.5% or 5.0% Chabanivske grain flour to the Myronivska spring wheat flour had a larger volume, better taste and appearance compared to the standard.
Conclusions. Waxi varieties (Chabanivske, Zhyvynka, Osoblyve, Alternatyvne), were developed in Ukraine, are characterized by high economically valuable traits and high indicators of grain quality. The main use of these varieties is grain and fodder. The Zhyvynka variety is characterized by high resistance (9 points) to 8 races of smut (Rs 1, Rs 4–Rs 7, Rs 9–Rs 11). The addition of Chabanivske grade waxy-millet flour to wheat flour improves its baking qualities and the taste of bread, while the films are additional fiber that promotes digestion

Purpose and objectives. The cultivation technology development was aimed at maximizing the potential productivity of the crop. To accomplish this, studies of heterogeneity are not only of theoretical but also of practical value, as knowledge of this phenomenon can open new opportunities to improve seed quality.
Materials and methods. In 2019–2020, the field and laboratory experiments were carried out in the rice crop rotation of the Institute of Rice of NAAS. The farming technique of the experiment met the requirements for experimentation, as Dospekhov B.A. described.
Results and discussion. This article covers the results on the performance patterns of new rice cultivars and their seed parameters, depending on the matrical heterogeneity. The yield in the field experiments across the study years ranged 8.05 to 11.68 t/ha, depending on a combination of the factors under investigation. It was found that the rice produced high yields in the plots sown with seeds from the upper part of the panicle, regardless of the cultivar. In the plots sown with seeds from the lower part of the panicle, there was a shortfall of planting material from 1.85 to 2.30 t/ha in comparison with the plots sown with seeds from the upper part of the panicle. Therefore, sowing seeds from the lower part of the panicle means irrational use of planting material, resulting in thinned crops and decreased yields, which in turn leads to the production of low-quality seeds.
Conclusions. Thus, the matrical heterogeneity-based selection of rice seeds from the upper part of the panicle in the primary stages of seed production is an important technological approach. This contributes to an increase in the yield and quality of rice seeds, allowing for accelerated implementation of new rice cultivars into production.

Purpose. To study and rationalize the main aspects of interregional transfer of breeding/plant innovations with export potential, of synergistic interaction between science, education and commodity production for more rapid innovative development of the country's regions.
Material and methods. The study methods were dialectical, abstract-logical, monographic, computational/constructional, economic-statistical, graphic modeling and others. The study was based on the Laws of Ukraine, regulations and guidelines on market relations in the agrarian sector and seed production; statistical data and reports of basic farms of the institute.
Results and discussion. For timely transfer of more adapted varieties, hybrids and parental components to production, we analyzed the numbers of accessions bred at the PPI nd.a. V.Ya. Yuriev NAAS in the State Register of Plant Varieties Suitable for Dissemination in Ukraine in 2021. As a result, we found that in 2021 the number of the major crop accessions bred at the Institute decreased by 15 compared to 2017, while during these years most breeding innovations were in demand from grain producers.
That is, there is no urgent need to create as many new varieties as possible, and the implementation of breeding innovations into production is gradual, with due account for producers’ wishes and the market changes. In particular, the most competitive winter wheat varieties were Rozkishna, Shulyndinka, Harmonika, Zapashna, Doskonala, and Zdobna; variety Stoir and hybrids Saturn and Yupiter were the most competitive rye accessions; Ad 256, Amos, Nikanor and Buket were the most competitive winter triticale varieties.
Analysis of the average sales of winter crop seeds of first generations in 2017–2021 indicated their gradual overproduction, as only 60–85% of these seeds were sold.
Regarding the production and sales of spring cereals, legumes and groats crops, we learnt that pea, millet and spring barley varieties were in the greatest demand from users of grain products (the sale percentage was 74%, 69%, and 60%, respectively). The most competitive pea varieties were Oplot and Haiduk; Modern, Avhur, and Ahrarii were the most competitive spring barley varieties; Spadshchyna and Uliublena were the most competitive spring wheat varieties; Konstantynivske, Vitrylo, and Kozatske were the most competitive millet varieties.
Conclusions. Thus, the results of the study for the period of 2017–2021 proved the feasibility of timely transfer of breeding/plant innovations with export potential (varieties, hybrids and parental components), which is important for scientific justification of seed production volumes for each generation and is a reference point for creating more profitable varieties and hybrids.

Published: May 2023

The article consists of three parts. The analysis of existing technologies of wireless power transfer (WPT) is carried out in the first part. It is noted that one of the factors that determines the choice of one or another WPT technology is the distance over which the power is transmitted and the type of electromagnetic (EM) energy used. The essence of WPT technologies in the near zone, Fresnel zone and Fraunhofer zone is explained. A generalized block diagram of the WPT system is presented. Areas of application and trends in the further development of the WPT technologies over short distances using induction and resonance methods, the WPT technologies over long distances, the technology of EM energy harvesting from the surrounding space and its conversion into direct current for powering low-power devices are considered.
The achievements of the team of the antenna laboratory of the Kharkiv National University of Radio Electronics (KhNURE) in the area of WPT are presented in the second part of the article. Namely, the electrodynamics’ approach is considered which is based on a single idea about the functioning of WPT systems and which include antennas and their circuits and ways of excitation with nonlinear elements. The stages of building a nonlinear mathematical model (MM) of the electrodynamics’ level of the WPT system are presented, according to which the entire WPT system, which generally includes the transmitting subsystem and the receiving subsystem, is considered as a single multi-input antenna system with nonlinear characteristics. The proposed MM provides a complete representation of the WPT systems operation of a wide class and purpose, in which fundamentally different WPT technologies are used.
The third part of the article presents new results related to continued research. The analysis of the adequacy of the developed MM of WPT system is carried out. The results of simulation of WPT systems with the induction method of energy transfer (near zone) and their comparison with theoretical and experimental data of other authors showed the reliability and universality of the proposed approach and the MM of WPT system developed on its basis.
Theoretical investigation of injection-locked differential oscillator
Authors: Rapin V.V. 
Published: May 2023

A preliminary analysis of published works on this topic showed that at present there is no sufficiently substantiated theory of such devices, and the approximate approaches used are rough and do not always meet the requirements of practice. The proposed transition from a differential self-oscillator to an equivalent single-circuit oscillator has not received a convincing justification.
This article presents a methodology for studying a synchronized differential oscillator using rigorous methods. A mathematical model of such oscillator is presented in the form of nonlinear differential equations obtained on the basis of Kirchhoff's laws. Their analysis made it possible to substantiate the transition to the model of a single circuit LC oscillator, equivalent to a differential one. A technique for such a transition is proposed, including the procedure for determining the nonlinear characteristics of the amplifying element of this self-oscillator, based on the nonlinear characteristics of two amplifying elements of the differential oscillator.
The mathematical model of an equivalent oscillator is represented by a non-linear differential Van der Pol equation in a dimensionless form, it is simple and accurate. This form of representation made it possible to single out a small parameter and estimate its value. In the case of small values of the small parameter, as is known, traditional methods can be used for its analysis. Thus, the task of studying the synchronization process of a differential oscillator is reduced to the study of the synchronization process of a Van der Pol oscillator. The presented results can be useful in the development of various devices based on synchronized differential oscillators.

The management of difficult choledocholithiasis, which accounts for 10—15% of all cases of bile duct stones, has not yet been definitively defined. One of the treatment options for difficult choledocholithiasis is laparoscopic choledocholithoextraction combined with choledochoscopy.
Objective — to evaluate the experience of a single centre in the treatment of difficult choledocholithiasis using laparoscopic choledocholithoextraction and choledochoscopy.
Materials and methods. A total of 47 patients, including 16 (34%) men and 31 (66%) women with difficult choledocholithiasis, were enrolled in the study and received treatment at our centre. All patients were operated on using laparoscopic choledocholithoextraction combined with choledochoscopy. Thereafter, the results of treatment were analysed for the cohort of patients. In the study, we identified the causes of difficult choledocholithiasis and evaluated the achievement of complete bile duct clearance, the surgery duration, total and postoperative bed days, complications, and mortality.
Results. All patients underwent laparoscopic choledocholithoextraction combined with choledochoscopy. The causes of difficult choledocholithiasis were as follows: characteristics of bile duct stones — 27 (57.4%), altered anatomy of the organs of the hepatopancreatobiliary zone — 11 (23.6%), specific location of bile duct stones — 9 (19.1%). After laparoscopic choledocholitoextraction combined with choledochoscopy, complete bile duct clearance was achieved in 95.7% of cases. The average duration of the operation was 130.0±14.7 min. The length of hospital stay after surgery was, on average, 14.3±1.7 days. 4 (8.5%) patients had complications corresponding to classes II (2 (4.2%)) and III (2 (4.2%)) according to the standardized Clavien‑Dindo classification (2009).
Conclusions. Laparoscopic choledocholithoextraction combined with choledochoscopy can be used as one of the technologies for the treatment of difficult choledocholithiasis.

The journal is entitled The Analysis of American Slang in The Kissing Booth Movie. The purpose of this analysis is to find out whether primary slang and secondary slang are used by the characters in the film or not, as well as to find the type of meaning of the slang meaning based on the context of the situation of the word itself. The data used is taken from the script of the film entitled 'The Kissing Booth'. The documentation method is used to collect data and qualitatively will be explained by the theory proposed by Chapman (2007) which divides the types of slang into Primary Slang and Secondary Slang. The functions of language include communication, the expression of identity, play, imaginative expression, and emotional release. In addition, the theory proposed by Leech (1981) divides the types of meaning into seven types including conceptual meaning, connotative meaning, social meaning, affective meaning, reflected meaning, collective meaning, and thematic meaning. Slang that is found in the script of the film, and there are several types of secondary slang also found in the script. Among the seven types of meaning, only conceptual meaning, reflected meaning, and affective meaning were found. The meaning of these slang words is in accordance with the context in which the word is used. Language, is a system of conventional spoken, manual (signed), or written symbols by means of which human beings, as members of a social group and participants in its culture, express themselves.
Teachers Experiences on Remote Learning During the Covid-19 Period
Authors: Wambaria Mary 
Published: May 2023

The World Health Organization (WHO) declared Covid-19 a global pandemic in March 2020, and warned about its highly contagious nature. Throughout the first quarter of 2020 many governments closed their schools temporarily in response to COVID-19 spread where more than 1.5 billion enrolled students of all ages from all around the globe experienced interruption of education. This aimed at reducing the chances of humans infecting each other with Covid-19, especially in places humans interact closely including educational institutions. This paper explores the experiences of the teachers on remote learning during the covid-19 period in four counties in Kenya gathered through a survey conducted in February 2021, collecting data by administering both open and closed ended questionnaire. The objectives of this study were to establish: availability of digital infrastructure for remote learning; the digital teaching and learning resources used by teachers in remote learning and teachers digital pedagogical skills necessary for remote learning. Distance education and online collaborative learning theories are discussed. A total of 116 teachers in both primary and secondary schools in Kenya responded to a questionnaire consisting of both quantitative and qualitative questions, with qualitative data analysed thematically and quantitative data with descriptive statistics. The result indicates that the teachers faced technological and pedagogical challenges teaching through remote learning. This study is intended to provide an early contribution to the understanding of teachers experiences in remote learning during the pandemic, an historical documentation, a point of reference for similar studies in the future and, hopefully, a first step towards collective reflection on possible avenues of development for our educational system build on informed policy decision making.

Published: May 2023

Individuals with autism spectrum disorders (ASD) make up a diagnosis characterized by a multifunctional neurocognitive disorder, based on a limited structure to perform nodal-synaptic interrelationships between the contents of learning. Likewise, this disorder may be associated with a set of comorbid symptom groups, which, regarding their intensity, may border with ASD main diagnosis and lead to basic errors that affect subsequent social- educational treatment. This study analyses most recurrent associated comorbid groups, as well as, if the presence of symptomatic comorbid groups is differential regarding group shape: normotypical and ASD groups. A total of 390 children participated in this study, 128 belonged to normotypical group and 262 did it to experimental group, subdivided into three levels of ASD. Results found through multivariate- test indicate that the whole dimension significantly affects group way intersection, age and sex (sig: .00). The post-hoc test analysis indicates this influence was differential regarding to the group type for the following dimensions: cognition, behaviour, psychoaffectivity, language and psychomotor disorder, while relative differences were not observed in specific- clinical dimension, where only epilepsy showed a differential result: no differences were found in general- clinic dimension.
Lay abstract
ASD´ diagnosis and treatment shows, to date, many weak points that need to be improved. Previous studies have shown how important is the psycho-educational component regarding ASD treatment, therefore it is necessary to understand the specific characteristics of the nuclear ASD diagnosis, in order to work out a specific therapy according to every single case.
In the current study, we examined and analysed ASD patients as well as participants showing comorbid symptoms such as epilepsy, in order to show how these comorbidities can reach a very high level, leading to a confused and wrong ASD nuclear diagnosis.
Therefore, it is essential to gain more insight into the specific diagnosis process, defining the ASD symptoms very precisely in order to develop more accurate and specific educational programs.
This study contributes to the improvement in ASD diagnosis, providing a large number of participants in order to study the relation between several comorbid symptoms and its reliability as ASD indicative factors or not.
Enhancing employability through hospital placements for Biomedical Science students
Authors: Alsam Selwa , Beard Louise , Hepburn Leanne 
Published: May 2023

Collaboration between Universities and hospitals has provided the National Health Service (NHS) with many excellent Biomedical Scientists through the placement year scheme. Here, we document the number of students joining the placement scheme and the number and type of hospital departments offering student placements over a 10-year period.
Prior to 2012, students were able to join fully-funded placements through the Higher Education Funding Council for England (HEFCE). Since then, there has been a fluctuation in numbers completing a placement year at the University of Essex, but the employability of these graduates remains consistently higher than our 3-year graduates. We demonstrate the positive impact of completing a placement year in an NHS hospital laboratory for students, and the contribution to university metrics in good degrees and graduate outcomes as well as the provision of much needed, qualified biomedical science staff to hospitals.
