Introduction of mechanized vermicomposting for utilization of vegetable waste of horticultural farms
Authors: Senchuk N.
Published: February 2022

The article deals with the expediency of using vermicomposting technologies in horticulture. Recommendations for the introduction of vermiculture technology in horticulture have been developed. Before the introduction of vermiculture technology, it is necessary to prepare the substrate. It is recommended to use the following composition of the substrate: plant tops; sawdust; tree leaves; peat, lime (up to 2 % by weight of the substrate). The substrate must undergo fermentation for at least 3 months, 3–5 months in winter. Storage of the substrate can last 8–10 months at a humidity of 70–80 %. The readiness of the substrate for consumption is determined by the ratio of carbon to nitrogen, which should be about 20. Acidity 6–8 pN. Selection of raw compost is carried out 2 times a year. Then it is used as fertilizer or sent for processing. If you process the shredded branches, the full selection can be done in 1.5 years. The dependence for determining the required biomass of earthworms on the productivity of vermigulture to process the established mass of substrate for the year of vermiculture has been established. It is determined that to create a vermigree with a capacity of 100 tons of substrate/year requires 10 kg of earthworm biomass, 500 tons of substrate/year – 45 kg, 1000 tons of substrate/year – 91 kg, 1500 tons of substrate/year – 137 kg, 2000 tons substrate/year – 182 kg. The given methodical bases of mechanized vermig farms give the chance to carry out the calculations necessary for processing of waste of vegetable origin in garden and park farms and reception of biohumus and biomass of earthworms. The introduction of such technology will allow the safe disposal of waste of plant origin of horticulture: tree leaves, waste from ﬂower production, etc. to obtain a highly effective fertilizer – compost.

Authors: Vdovenko S. , Hetman N. , Didur I.
Published: February 2022

The article aims to study the intensity of heavy metals (lead, cadmium) accumulation in the vegetative mass of milk thistle on different soils. Based on the analysis of literary sources, it was found that milk thistle has a wide range of applications and, due to the presence of biologically active substances in its composition, has useful and medicinal properties. However, we have noted the plants liability for heavy metals accumulation which can affect the quality and safety of milk thistle. The purpose of the research is to study the intensity of the accumulation of heavy metals by the vegetative mass of milk thistle when grown in a modern feld crop rotation on different soils. The article presents data from scientifc literary sources and the results of our own feld and laboratory research. The study results reveal an excess of the maximum permissible concentrations of the toxicants in the vegetative mass under growing milk thistle on light gray podzolized, gray forest and dark gray podzolized soils with a lead content of 2.5 mg/kg–2.8 mg/kg and cadmium content of 0.2 mg/kg–0.22 mg/kg. In particular, an excess of the maximum permissible concentrations in the vegetative mass for lead by 1.97 – 2.86 times and cadmium – by 1.18 – 1.44 times was noted. The lowest content and the lowest coefcient of accumulation of lead and cadmium in the vegetative mass of milk thistle was observed on dark gray podzolized soils, and the highest – on light gray podzolized soils. It was also found that the hazard coefcient of lead and cadmium in the vegetative mass of milk thistle exceeded 1.0, which indicates the low quality of this raw material. The vegetative mass of milk thistle, which was grown on dark gray podzolized soils, was characterized by the lowest hazard coefcient, while the highest – on light gray podzolized soils.

Methodological approaches in the study of agroecosystems’ biodiversity
Authors: Lavrov V. , Grabovska T.
Published: February 2022

In agroecosystems, the structure and dynamics of taxonomic and functional biodiversity differs signifcantly from the local intact identical standard types of ecosystems and depends on the type and duration of management, the degree of environmental friendliness of the applied technologies. Agroecosystems signifcantly affect the biodiversity of the surrounding areas. To harmonize its preservation in agricultural landscapes with the aim of optimizing agriculture, it is necessary to improve the methods of its research. It is established that the choice of methodological bases (principles, criteria and methods) of biodiversity research depends on the purpose and hierarchical level of ecosystem analysis, scale of the researched question, as each group of living organisms selected according to a certain principle has its peculiarities, identifcation and characterization of which requires appropriate methods, necessary knowledge, special equipment and other resources of scientifc research. It is advisable to apply a systematic approach, biotic and / or ecological criteria and indices for assessing / analyzing the diversity of biota, the ratio and characteristics of its ecological groups, indicator capacity of species, multifunctional relationships (within and between taxa and their environment) and other ecological indicators describing the state of integrity of the agroecosystem, its functional diversity and dynamics. Gradient analysis by changing the values of determining factors is appropriate for zoning the distribution in space of different levels of agroecosystem transformation and its biodiversity. Retrospective analysis makes it possible to identify the causes, characterize the dynamics of changes in biodiversity in the past and future and justify the directions of its conservation.

Published: February 2022

Parsnip is a valuable vegetable crop. Its roots are used in various sectors of the economy due to its rich chemical composition. But the area under the crop is insignifcant. Despite the signifcant number of scientifc publications, the issue of parsnip growth in the conditions of Transcarpathiahas not been explored. Therefore, the aim of our research was to study the processes of growth and development, yield and preservation of parsnip roots for cultivation in soil and climatic conditions of the foothills of Transcarpathia. When studying the phenology of varieties, it was noted that the period from the emergence of seedlings to the formation of a rosette of leaves was the shortest in the variety of Hungarian selection Felhosszu and lasted 31 days. The shortest interphase period "rosette formation – root formation", which lasted 41 days, was recorded on the variant with the variety of German selection Boris. The study of the biometric parameters of the rosette of parsnip leaves showed that its height and diameter are dominated by the Felhosszu variety – 69.8 and 38.4 cm, respectively. The number of leaves in the rosette (6.4 pcs.) was the maximum in the Borisvariety. The standard variety Petryk was distinguished by its length (26.8 cm), diameter (4.9 cm) and weight of root crops (158.8 g). This variety formed the highest yield – 56.7 t/ ha, within which 90.3 % were marketable products. The Boris variety formed a marketable harvest at the level of 45.9, and Felhosszu – 44.9 t/ha, which was 87.4 and 82.8 % of the total harvest, respectively. To study the best way to preserve products, we used three methods of storage: bulk in boxes, unwashed and washed in plastic bags. Maximum weight loss was observed during storage of root crops in bulk in boxes. They ranged from 6.2 to 6.7 %. The largest share of the mass was lost by the food organs of the German selection variety. But these losses in different storage methods were distributed unevenly over time. At the beginning of storage they were high enough, by January-February they sharply decreased, and further grew again. Among the methods of storing roots, the best one was to store them unwashed in plastic bags. In this way, the yield of marketable roots after long-term storage from late October to late May ranged from 92.8 to 93.6 % and was highest in the Petryk variety . This variety gave the highest yield of marketable roots and for their preservation in bulk in boxes and washed in plastic bags.

Published: February 2022

The studies conducted in the contrastive by their hydrothermal conditions 2019–2020 examined F 2 hybrid populations created by crossing different early ripening varieties of soft winter wheat. Most of F 2 populations used in various crossbreeding schemes of early ripening, middle-early, medium-ripening, and middle-late varieties for both average number of grains in the ear and its maximum manifestation, signifcantly exceeded the original forms and characterized by signifcant formation. The obtained results indicate a signifcant inﬂuence of the selected pairs for hybridization and hydrothermal conditions of the year on the formation of the number of grains in F2 populations of soft winter wheat. However, hybrid populations with early ripening varieties as the maternal form are less susceptible to adverse hydrothermal conditions. The research results give ground for defning hybrid populations, which had less than the average number of grains in the ear for F 2 in the most contrastive hydrothermal conditions and were characterized by high rates and frequency of positive transgressions, namely: Myronivska early / B.Ts. semidwarf; Myronivska early / Zolotokosa.; Myronivska early / Chorniava; Kolchuga / Stolychna; Myronivska early / Vdala; Shchedra nyva / Vidrada; Antonivka / Stolychna. The identifed correlations between the degree of phenotypic dominance in F1 and the degree and frequency of positive transgressions indicate an insignifcantly weak direct to inverse relationship between these indicators. At a reliable level, in the years of research, a strong (r = 0.774…0.893) correlation was found with the degree of positive transgressions and the frequency of recombinants.
Key words: degree and frequency of transgression, soft winter wheat, maturity groups, parental forms, variability, number of grains of the main ear, population F2, degree of phenotypic dominance.
Dietary supplementation of sodium bicarbonate, probiotic and L-ascorbic acid affects laying performance and eggshell quality in older hens
Authors: Dey B , Ray BC , Saha DJ
Published: February 2022

Eggshell quality issues are a substantial hidden cost for egg producers and a matter of concern for older hens. To address the issue, a trial was conducted to determine the effects of various dietary supplements on eggshell quality in older hens. A total of 48 Hy-line brown commercial laying hens aged 76 weeks were considered for the experiment. There were four dietary treatments with three replications per treatment, maintaining four birds per replication. All the diets had similar energy and protein contents except for the doses of test ingredients. The diets contained T1 (control: layer mash feed), T2 (control + 3g NaHCO3/kg feed), T3 (control + 2 g/kg multi-strain probiotics) and T4 (control + 0.4 g/kg L-ascorbic acid). Laying performances and eggshell qualities were measured three times during the whole experimental period. Dietary inclusions of all the test materials reflected a significant increase in egg production (p<0.0001). Similar to egg production, a rise in egg mass output (p=0.0006) was depicted in all the treated groups. An improvement (p=0.0001) in feed conversion ratio (feed:egg mass) was obtained due to the feeding of the additives as well. The addition of NaHCO3, a multi-strain probiotic, and L-ascorbic acid to the diet increased shell percent (p=0.0611) and shell thickness (p=0.0293). The inclusion of three test ingredients in the layer diet showed the better shell thickness (p=0.0293) than the control group. Taken together, it may, therefore, be opined that the dietary supplementation of sodium bicarbonate, multi-strain probiotics, and L-ascorbic acid significantly improves the quality of eggshell and overall laying performance of older hens.

Summary. Oral hygiene is a complex set of preventive measures that involve usage of objects and means aimed at preventing the development of pathological processes in the oral cavity. For oral hygiene, a complex of products is used: tooth powders, pastes, gels, rinses, elixirs, balsams, chewing gum and care items – toothbrushes, dental floss, intradental brushes and toothpicks. Tooth powders are made from chemically precipitated chalk (calcium or magnesium carbonate), both abrasive components and various excipients (biologically active substances, fillers, adsorbents, flavors, bleaches, dyes, flavors, anti-inflammatory and flavor components). Hygienic form in the form of tooth powder in comparison with other forms of release (balms, gels, solutions, pastes) has the ability to better clean the tooth enamel surface. Powder such a tool cleans the surface of the teeth not only from soft plaque, but also from hard, and also neutralizes the acids formed in the oral cavity, thus regulating the microbiocenosis. In addition, it has disinfectant and deodorizing properties. The conducted researches allowed to develop the optimized structure, technology of hygienic for itself in the form of tooth powder. Tooth powder with extract Salvia officinalis will prevent diseases of the oral cavity of various etiology, thoroughly remove plaque, regulate microbiocenosis and give a pleasant smell and flavor – will refresh the breath. And also to control the quality of tooth powder with Salvia officinalis extract. In particular, the quality control of tooth powders was carried out in accordance with the requirements of the regulatory documentation of GOST 592-77 «Tooth powder» and organoleptic and physicochemical parameters.

Purpose. Comparative analysis of the strength of hybrid restoration composites of light polymerization during their local load using the phenomenon of acoustic emission and fractographic studies of fracture samples. Materials and methods. For comparative studies, hybrid dental composites of domestic and foreign production were selected: Latelux (Latus, Ukraine), Tetric N-Ceram (Ivoclar Vivadent, Liechtenstein), Charisma Classic (Kulzer, Germany). Disc samples 13 mm in diameter and 5 mm thick, which were made in a specially designed form, were used for testing. The samples were loaded on an SVR-5 installation using a ball indenter with a speed of its movement of 0.002 mm/s until the samples were completely destroyed. During the experiments, acoustic emission information was simultaneously recorded using the SKOP-8 measuring system. Electron microscopic studies of materials were performed using a scanning electron microscope (SEM) ZEISS EVO 40XVP. Results. Under loading by local compression, mixed types of fracture occur in the dental composites under study, with the difference that plastic deformation is somewhat less pronounced in the Charisma Classic composite and more radial macrocracks propagate in Tetric N-Ceram and Charisma Classic. Conclusions. Comparison of the sizes of chips in different materials, which were formed as a result of the propagation of conical cracks, makes it possible to make the result that during the local compression load of the Latelux composite new fracture surfaces were formed, much smaller than in the other two materials. Their formation was accompanied by AE signals with significantly lower amplitudes and then energy than in the Tetric N-Ceram and Charisma Classic composites. Key words: light polymerization composites for dental restoration, power loading, fractographic studies, acoustic emission.

Relevance. It is believed that the main cause of carious demineralization is microorganisms. However, the deterioration of the process is facilitated by the disruption of mineral metabolism in the oral cavity and, primarily, due to the insufficient supply of minerals naturally, from saliva. Aim: to study the effect of reduced functional activity of salivary glands on the intensity of the carious process and the sensitivity of teeth to stimuli in persons who have undergone COVID-19. Materials and methods. The studies involved 27 patients aged 18–42 years, 17 of them suffered from COVID-19. To compare the results, a group of individuals in the same age range who did not have COVID-19 was selected. All studied salivation rate, caries intensity, Green-Vermillon oral hygiene index (G-V), enamel solubility by TER test scale and the sensitivity of teeth to stimul. Results. In patients with COVID-19, immediately after recovery, pronounced hyposalivation (0.27±0.04 ml/min) was observed. After 1 year, this figure has not changed significantly; the intensity of caries increased by 35 %; the G-V index was at the middle level; the TER test had high rates and most of the patients with COVID-19 developed tooth hyperesthesia, which indicated that demineralization prevailed over remineralization. Conclusions. 1. In patients who have undergone COVID-19, enamel resistance decreases and the risk of developing a carious process increases and the appearance of hypersensitivity of teeth due to insufficient natural mineralization due to a decrease in the amount of saliva released – the main source of minerals entering the tooth enamel. 2. The microbial cantamination factor of demineralized enamel exacerbating the process is also not excluded. However, with good oral hygiene, the role of this factor is significantly reduced. 3. Persons who have undergone COVID-19 need dispensary supervision by a dentist, as well as medical and preventive measures that reduce the risk of developing a carious process. Key words: Patients who were sick with COVID-19; salivary gland function; enamel demineralization; caries intensity; tooth hypersensitivity.

Abstract. The pathogenesis and clinical course of chronic generalized periodontitis due to coronavirus disease acquires rapidly progressive signs, which significantly reduces the quality of life in the postcovid period and requires scientists to find other effective, minimally invasive techniques that will complement and increase the effectiveness of such treatment for patients, that will reduce the usage of pharmaceutic drugs. Relevant, in this context, technique to which attention should be paid is Helbo therapy, using a laser «Helbo Thera Lite», which has a wide range of advantages over analogues. Changes in periodontal indices after a comprehensive dental treatment with additional inclusion of the course of Helbo therapy and the appointment of a corrective treatment complex have a significant tendency to improve the clinical picture in the oral cavity, which makes the use of this technique especially relevant. It will facilitate the introduction of the proposed treatment regimens of chronic generalized periodontitis in the postcovid period to the dentists in the future.

Abstract. Modern dentistry dictates certain rules, including the necessity to consider the etiology of the development of dentognatic anomaly and/or deformation in order to choose a proper treatment method for an orthodontic patient. Etiology is closely related to the growth and development of the human dentognathic system, which have different mechanisms at different stages and are influenced by various factors. We propose for review a sequenced and phased chronology of growth and development of the maxillofacial system in terms of age. Key words: growth and development of dentognatic system, the growth of the upper jaw, the growth of the lower jaw, active growth, completion of growth, features of the growth and development of the human dentognatic system, systematization.

Annotation. Аdentia has a negative effect on the development of the dentition, and the absence of the first molars creates conditions for a progressive decrease in the height of the bite, which does not lend itself to self-regulation and leads to disruption of the functioning of other organs of the dentoalveolar system and the occurrence of complications. Orthodontic closure of dental arch defects restores the integrity of the dentition and improves the functioning of the dentition as a whole. The aim of this work was to study the results of orthodontic treatment of young patients with edentulous permanent teeth using microimplants. According to the results of the treatment of 17 patients with edentulous teeth with the actually developed orthodontic method using microimplants, positive results were obtained regarding molar protraction, which is faster than using the conventional method and the rotation of mesial teeth arising from molar protraction is leveled. Key words: adentia, orthodontic treatment, microimplant.

Purpose: to study the methods for determining the dental age of children described in scientific sources, as well as to assess the availability and complexity of such methods and the reliability of the results obtained. Materials and methods. Literary review of world scientific publications on modern methods for determining the dental age in children. Results. The literature presents various methods for assessing dental age, which can be classified as: visual, radiological, morphological, biochemical, histological, and the like. Each of these methods has a large number of copyright modifications, depending on the region of residence, belonging to a particular race or gender, the methodology of the research itself, and many other factors. Dwelling on individual techniques, one can analyze both the complexity and availability of their implementation, and the reliability of the expected results. Conclusions. Methods based on the study of the formation of bone and dental structures are the most common, accurate and effective in determining the dental age of children, since they practically do not depend on environmental factors, are not exposed to environmental and social factors and are mostly genetically determined. Key words: dental age, biological age, method for determining dental age, orthopantomogram.

Authors: Ramos-Saldaña Santos
Published: February 2022

En la presente investigación fue de enfoque cuantitativo, nivel descriptivo correlacional y diseño no experimental de corte transversal. La población se conformó de 90 estudiantes del primer ciclo del IESTP “Pacarán”. La muestra fue censal. Se aplicaron la Escala de clima emocional y el Cuestionario sobre capacidades de liderazgo. Entre los resultados, se observó una respuesta positiva en la mayoría de preguntas de ambos cuestionarios. Se obtuvo una correlación de Pearson con un valor de 0,914. Los resultados sugieren que el clima emocional sí incide significativamente en el desarrollo de las capacidades de liderazgo en estudiantes del primer ciclo del instituto estudiado. Ante lo cual se recomienda modernizar y restructurar la dinámica pedagógica para mejorar el clima emocional y con ello promover un mejor rendimiento académico en los estudiantes de dicho instituto.
Bone Regeneration with Platelet-Rich Fibrin Following Surgical Management of Periapical Lesion: Achieving Success in a Resource-limited Area. A Case Report
Authors: SO Gbadebo , AO Oyediran , TA Egbe
Published: February 2022

Background: Intra-oral bony defects following periradicular surgery have been documented to have high selfregenerating potential (especially when small). However, early permanent rehabilitation of tooth to function is important post-surgery. Thus, there is a need to enhance bone healing through regeneration due to the prolonged natural bone healing process. Many materials have been proposed and used but the Platelet-rich fibrin (PRF); a second-generation platelet with fibrin membranes enriched with platelets growth factors is an autologous material, easy to produce and a cost-effective way of regenerating bony defects. Aim: To assess and report the regenerative potential of PRF following periradicular surgery. Methodology: A case report of a 60-year old female who presented with a chronic periapical abscess in relation to the upper right incisors. A periapical pathology of 30mm in its widest dimension was present on the radiograph. Following root canal treatment, the patient had periradicular surgery to remove the apical cystic lesion. The bony defect was filled with autologous platelet-rich fibrin (produced through centrifuging of peripheral blood) to stimulate bone regeneration, and the tooth was reviewed for one year. Result: The one-year review post periradicular surgery showed good healing and bone regeneration. Conclusion: The report showed the use of PRF in regeneration of intra bony defect post degranulation of periapical lesion (after removal of cystic lesion) as an effective and cheap way of achieving regeneration.

The COVID-19 pandemic has had a massive impact on the world at large with over a hundred million cases and millions of deaths, the physical impact of the disease is obvious. There is another aspect of the pandemic’s effect, however, that is largely left under discussed. Alongside the disease itself, the COVID-19 pandemic brings the mental health challenges that the many changes from living in such a time creates. Throughout this paper, the impact that this pandemic has had on the mental health of the population at large will be examined. Along with this, the effect of this mental health impact on the demand for mental health services will be examined. The impact of COVID-19 will also be compared with those of previous pandemics while exploring how this increase of demand is being addressed by those in the field. To gather all the necessary information for exploring these topics, a search of the Web of Science data base was conducted. Initial searches revealed an obvious increase in mental health problems amongst the general population during the pandemic, with grief, anxiety, and depression all showing significant increases, with increases of almost 10% in some cases. Searches into the providing of mental health care in the pandemic environment quickly revealed the trend towards telemedicine in order to meet the increased demand safely. This and other changes in the field of mental health have been taking place over the course of the pandemic allowing for their effectiveness and usage to be easily studied. With all this in mind, this paper will attempt to thoroughly explore all of these ideas and paint a clear picture of the impact that the COVID-19 pandemic has had on the mental health of the public and on the providing of mental health services.

One of the most serious complications following kidney transplantation is graft thrombosis. This can be associated with extra morbidity for the patient as well as the need for dialysis. We present a case of the late exploration in a poorly perfused kidney following living donor kidney transplantation, which was saved by explantation, reperfusion on the back table and re-transplantation.
