Published: October 2022

В статье представлены результаты исследований влияния минеральных макро- и микроудобрений на урожайность и качество семян люпина белого. Полевые опыты проведены в 2013–2015 годах на кафедре растениеводства, селекции и овощеводства Белгородского ГАУ. Объект исследований — высокоинтенсивный сорт люпина белого Дега. Погодные условия в период проведения исследований характеризовались повышенным температурным режимом и низкой влагообеспеченностью. Почвенный покров опытного участка представлен чернозёмом типичным среднемощным малогумусным тяжелосуглинистого гранулометрического состава. Учётная площадь делянки — 10 м2, повторность четырёхкратная, размещение вариантов в повторениях систематическое. Полевой опыт включал следующие варианты внесения удобрений: контроль (без внесения удобрений), N60Р60К60, N60Р60К60 + «ЖУСС-2» (Cu — 32–40 г/л, Мо — 17–22 г/л), N60Р60К60 + «ЖУСС-3» (Cu — 16,2–20 г/л, Zn — 35–40 г/л). Аммиачную селитру, суперфосфат двойной и хлористый калий вносили под предпосевную культивацию, а жидкие удобрительные стимулирующие составы «ЖУСС-2» и «ЖУСС-3» использовали для внекорневой подкормки растений люпина в фазе бутонизации. В результате исследований установлено, что применение удобрений оказывало положительное влияние на урожайность, содержание сырого протеина в семенах, сбор сырого протеина урожаем. Внесение полного минерального удобрения (N60P60K60) и комплексное использование макро- и микроудобрений (N60Р60К60 + «ЖУСС-2», N60Р60К60 + «ЖУСС-3») в засушливых условиях вегетации способствовало получению высокой урожайности семян — 2,18, 2,50 и 2,45 т/га с содержанием сырого протеина 37,2, 38,2 и 37,9% соответственно.

Paper reports on the influence of mineral macro- and micro-fertilizers on productivity and seed quality of white lupine. Field trials took place in 2013–2015 at the department of Crop Production, Plant Breeding and Vegetable Production in Belgorod State Agrarian University. High-intensive white lupine “Dega” performed as the object of study. High temperature and low water availability were the parameters of weather in the period of investigations. Soil was chernozem with low humus and high loam contents. Plot size — 10 m2, number of repetitions — 4. Variants were arranged systematically. Experimental design: control (no fertilizers), N60Р60К60, N60Р60К60 + “ZHUSS-2” (Cu — 32–40 g/L, Мо — 17–22 g/L), N60Р60К60 + “ZHUSS-3” (Cu — 16.2–20 g/L, Zn — 35–40 g/L). Ammonium nitrate, double superphosphate and potassium chloride were applied in the period of pre-sowing tillage. Liquid fertilizers “ZHUSS-2” and “ZHUSS-3” were used for top dressing at the stage of bud formation. Fertilization positively affected crop productivity, crude protein content in seeds and yield in general. Application of N60P60K60 in combination with “ZHUSS-2” or “ZHUSS-3” under dry conditions resulted in high seed productivities of 2.18, 2.50 and 2.45 t ha-1 as well as crude protein contents of 37.2, 38.2 and 37.9%, respectively.

Considering the FAO perspectives for agriculture towards 2030 many natural sources will be no longer profitable for the synthesis of many biomaterials; however, triticale (X Triticosecale Wittmack) is a cereal crop synthetized to withstand marginal agricultural conditions, used primarily as fodder throughout the world. The synthesis of a novel anionic hydrogel with pH stimulus-response was developed based on Eronga triticale starch as sustainable biomass, using citrate (pKa~3.1, 4.7 and 6.4) as crosslinking agent. By scanning electron microscopy and X-ray diffraction, starch granules exhibited size and semi-crystallinity A-type. The presence of the anionic sensing group (COOH) was verified by infrared spectroscopy, and by a thermal analysis the hydrogels exhibited four endothermic curves (115-393°C, ~1.4-38 kJ/mol activation energy). The rheological analysis showed viscoelastic tendency (G’>G’’) and good stability (Tan δ<1) in the frequency, time, and strain sweeps. Gastrointestinal pH sensitivity (~2-7.8) was verified (α≤0.01) following Fick’s diffusive parameters, which resulted in a tendency to gradually release bovine albumin with the increase of pH~3-7.8 by anomalous and case-II diffusion with greater release at pH~7.8/3.5h (80-96%). The hydrogel showed good physical and diffusion performance, however, we aim to expand the biomaterials area using triticale starch due to its limited investigations, low-cost and green modification.

Published: October 2022

The reaction mechanism of the Pd/Senphos-catalyzed trans-hydroboration reaction of 1,3- enynes was investigated using various experimental techniques, including deuterium and double cross-over labeling experiments, X-ray crystallographic characterization of model reaction intermediates, and reaction progress kinetic analysis. Our experimental data are in support of an unusual outer-sphere oxidative addition mechanism where the catecholborane serves as a suitable electrophile to activate the Pd(0)-bound 1,3-enyne substrate to form a Pd-eta3-pi-allyl species, which has been determined to be the likely resting state of the catalytic cycle. Double cross-over labeling of the catecholborane points toward a second role played by the borane as a hydride delivery shuttle. DFT calculations reveal that the rate-limiting transition state of the reaction is the hydride abstraction by the catecholborane shuttle, which is consistent with the experimentally determined rate law: rate = k [enyne]0 [borane]1 [catalyst]1. The computed activation free energy DG‡ = 17.7 kcal/mol and KIE (kH/kD = 1.3) are also in line with experimental observations. Overall, this work experimentally establishes Lewis acids such as catecholborane as viable electrophilic activators to engage in an outer-sphere oxidative addition reaction and points towards this underutilized mechanism as a general approach to activate unsaturated substrates.
Iteroselectivity, the missing sibling of chemo-, regio- and stereoselectivities
Authors: Lavendomme Roy , Jabin Ivan
Published: October 2022

Iteroselectivity is the selectivity that governs the number of repeating chemical transformations that occur on a substrate bearing multiple identical reactive functions or when the reactive function is regenerated like in the case of polymerization. This new concept of selectivity is defined and compared with the classical chemo-, regio- and stereoselectivities encountered in chemical synthesis. Examples of iteroselective reactions are given ranging from very common reactions such as electrophilic aromatic substitutions to advanced methods involving large supramolecular complexes.

The desire to increase the energy density of stoichiometric layered LiTMO2 (TM = 3d transition metal) cathode materials has promoted investigation into their properties at high states of charge. Although there is increasing evidence for pronounced oxygen participation in the charge compensation mechanism, questions remain whether this is true O-redox, as observed in Li-excess cathodes. Through a high-resolution O K-edge resonant inelastic X-ray spectroscopy (RIXS) study of the Mn-free Ni-rich layered oxide, LiNi0.98W0.02O2, we demonstrate that the same oxidized oxygen environment exists in both Li-excess and non-Li-excess systems. The observation of identical RIXS loss features in both classes of compounds is remarkable given the differences in their crystallographic structure and delithiation pathways. This lack of a specific structural motif reveals the importance of electron correlation in the charge compensation mechanism for these systems and indicates how a better description of charge compensation in layered oxides is required to understand anionic redox for energy storage.
Inverse Radon transform without singularity for rays with a point focus
Authors: Vikhtinskaya T. G. , Lapitan K. E. , Nemchenko K. Е.
Published: October 2022

Background: The need to reconstruct images from their projections has been repeated many times as a means of studying an object in a wide variety of fields of science, technology and medicine.

The basis of this method is the penetration through object of beams under different angles and the acquisition of a shadow image on the surface sensitive to these rays. Since that the tissues and bones have different absorption densities from such projections it is possible to get a reasonably accurate idea of the presence of pathological formations or lesions.

Despite all the advantages of tomography, it has disadvantages. One of the most serious is the exceedance of radiation for humans. Therefore, there are several options for reducing the burden on the patient, one of which is the use of tomosynthesis instead of CT scanning. Tomosynthesis occupies an average position in informativeness between computer tomography and radiology not much higher than the dose of the latter. As a result, work is underway worldwide to improve the tomosynthesis method to increase the number of diseases that can be diagnosed by this method and to improve the quality of the images obtained.

Objectives: Defines the efficiency of the image recovery method when using the Radon transform in general form compared to classical methods.

Materials and methods: Mathematical physics methods for reconstructing medical images, namely the Fourier transform in the polar coordinate system and the Radon transform.

Results: As a result of the work done, an expression for the reverse Radon transform was obtained and the work of the tomograph with point focus of X-ray rays was modeled. When comparing different reconstruction techniques with the original image, the Radon transform is generally more accurate.

Conclusions: Despite the considerable increase in the time of reconstruction computation, about three times, this method has practical advantages in the case of detection of pathologies that only develop and have no clear boundaries or in the case of detection of small objects.

Authors: Pleskach L. , Virchenko V.
Published: October 2022

Species composition of epigeic bryophytes of the Olexandria Dendrological Park, located in the northeast of the Right-Bank forest-steppe of Ukraine, was studied. The research was conducted in 2017–2019. As a result, 40 species of 25 genera, 14 families, 7 orders, 2 classes, and 1 division were registered. A taxonomic analysis showed that the orders Hypnales (14 species), Pottiales (9 species) and Bryales (9 species) are represented best. The main families were as follows: Pottiaceae (9 species), Brachytheciaceae (7 species), Bryaceae (5 species), Amblystegiaceae and Mniaceae (4 species each). The most speciose were the genera Bryum (5 species), Brachythecium (4 species), Tortula (4 species) and Plagiomnium (3 species). Among the identified taxa, two species, (Barbula сonvoluta and Bryum rubens) are regionally rare in the Forest-Steppe zone of Ukraine. In the historical part of Olexandria, five species Ceratodon purpureus, Oxyrrhynchium hians, Hypnum cupressiforme, Atrichum undulatum, and Bryum moravicum were the most common epigean bryophytes. In the western part of the Dendropark, the prevalent species were Atrichum undulatum, Bryum moravicum, Oxyrrhynchium hians, Hypnum cupressiforme, Brachytheciastrum velutinum, and Hygroamblystegium varium, in the central part – Bryum moravicum, Hypnum cupressiforme, Ceratodon purpureus, and in the eastern part – Fissidens taxifolius, Fissidens viridulus, and Brachythecium rutabulum. Twenty species (50 % of the identified taxa) were obligate epigees while the other 20 species belonged to the facultative epigees. In 2018, a new species to the Dendropark’s bryoflora, Ephemerum minutissimum, was found in an oakery (locality 14). It grew there together with Dicranella heteromalla, Bryum rubens, Barbula convoluta, Ceratodon purpureus, Tortula acaulon, and Weissia brachycarpa. This is the second record of E. minutissimum from Ukraine. The highest number of epigeic moss species was registered in the central part of Olexandria (29 taxa). At present, the epigeic bryoflora of the Dendropark’s historical part comprises 44 % of its whole bryoflora (90 species).
Molecular genetic data in terms of associative and population genetics
Authors: Atramentova L. , Ehyakonandeh H.
Published: October 2022

In studies on associative genetics of various multifactorial diseases, it is most often found that the minor allele’s frequency in the group of patients is higher than in the group of healthy people. Due to reduced adaptation, the minor allele manifests itself as a disease. In the group of patients, the number of homozygotes by major allele is reduced, the number of heterozygous carriers of the provocative allele is increased, and the frequency of homozygotes by the provocative allele is significantly increased. The aim of this article was to analyze the unusual result for SNP 1298A/C of the MTHFR gene in multiple sclerosis, previously obtained by one of the authors. The allele frequencies in the control group and in the group of multiple sclerosis do not differ, but the distribution of genotypes in the patients does not correspond to the Hardy–Weinberg ratio in compare to healthy people. Among patients, the number of heterozygotes is increased and the number of each homozygote is decreased. The increase in the proportion of heterozygotes can be explained by the presence of one provocative allele, but the large shortage of homozygotes for the minor allele is unclear. To explain this fact, the composition of the group of patients was analysed. The patients are of different ages, this group is heterogeneous in sex and form of multiple sclerosis, but none of these indicators has not be taken into account in the analysis of the distribution of genotypes. The age of the disease is a diagnostic sign and may depend on the genotype. The manifestation of multifactorial diseases depends on gender as well. Clinical forms of the disease usually have a different genetic basis. Due to the neglect of these conditions, a genetically heterogeneous group is formed, and any result, difficult for explanation, can be obtained. The lack of СС genotypes may be due to increased mortality, which reduces the probability of patients to be investigated in the sample. These facts once again indicate the need to form homogeneous groups for research on associative genetics.
Association of Balantidium coli and intestinal coccidia (Eimeria, Cryptosporidium, Isospora) in domestic pigs in Azerbaijan
Authors: Hajiyeva N.
Published: October 2022

The purpose of our work is to determine the prevalence of associative infections of domestic pigs in the farms of Azerbaijan. The research was conducted in 2009–2015. The faeces samples were taken from 2272 domestic pigs of different ages kept in private farms in the districts of Balaken, Zagatala, Shamakhi, Ismayilli, Guba, Khachmaz, Khudat, Salyan and Absheron peninsula in Azerbaijan, in the region of the Great Caucasus. Species composition, infection intensity, and ecological features of the pig parasitic protozoans had not been studied prior to our research. In the course of our study, the associative invasions in domestic pigs were as follows: Eimeria and Isospora oocysts were found in 582 pigs (25.6 % out of the total animals examined), Eimeria and Cryptosporidium oocysts in 622 pigs (27.4 %), Eimeria oocysts with Balantidium cysts in 273 pigs (12.0 %), Isospora and Balantidium oocysts in 18 pigs (0.8 %), Eimeria, Isospora and Cryptosporidium oocysts were detected in mixed form from one pig only (0.04 %). None of the analysed faecal samples contained a four-component mixed parasitic invasion. The two-component mixed infestations, viz. Eimeriosis + Cryptosporidiosis and Eimeriosis + Isosporiasis, were recorded during the whole year, while the prevalence of Eimeriosis + Balantidiosis and Isosporiasis + Balantidiosis mixed infestations decreased in summer. Keeping pigs of different ages in one pen at the farms increases the risk of associative invasion. In the pig farms equipped with various technological devices, the epizootic situation is different. If the animals kept traditionally, the infestation with associative invasions is much higher. Among the animals that live in unventilated pens with a wooden floor, the intensity of mixed infestation is the highest that results in the extremely high economic loss in such farms. In the animals kept in warm pens with high humidity, the invasion intensity is high even in winter. The primary reasons of this phenomenon are heat and humidity that create favourable conditions for the exogenous development of coccidian oocysts.

Analysis of the existing basic collections and identification of the core collections with clearly defined properties are important stages of the plant genetic banks activities. The NCPGRU pea collection has not been studied through this lens. The article presents results of the study of pea (Pisum sativum L. subsp. sativum) accessions as donors of valuable breeding traits for its multipurpose use in agriculture and processing industries. We examined 307 accessions representing the breeding material from the working pea collection of the Laboratory of Grain Legume Breeding of the Plant Production Institute named after V.Ya. Yuriev and the collection accessions of various eco-geographical origins of the National Center for Plant Genetic Resources of Ukraine (NCPGRU). Eleven donors were selected by one or more important agronomic traits in combination with valuable economic characteristics (yield, performance, protein content in seeds, disease resistance (Fusarium wilt and Ascochyta blight)). The cultivars Modus, Efektnyi (multi-flowering (fn fna), leafless (tendril) (af)), Tsarevych (seed shedding resistance (def), leafless (af)), and SL DTR 94-120 (multi-flowering (fn fna), luhansk type of determinancy (d)) were chosen as donors for the grain pea breeding. Orpella (anthocyanin pigmentation of the corolla (A)) and Rezonator (stem length (Le)) were used for the grain/fodder pea breeding; Kharkivskyi Yantarnyi and Banan (seed culinary qualities) – for the groats pea breeding; Stambovyi (parchmentless pods (pv), fascicle stems (fa fas) and Asgrow sead (wrinkled seeds (r), leafless (af), multi-flowering (fn fna)) – for the garden pea breeding; Violena (the rb gene carrier – amylose-free starch) – for the technical pea breeding. All the accessions proved their donor capacities. A qualitatively new input material for practical selection has been derived by means of hybridization with some cultivars (Kharkivskyi Yantarnyi, Banan, Tsarevych, Violena, Asgrow seed). Further study of the NCHRRU pea collection aimed at identification of valuable accessions and creation a core collection is essential.

Published: October 2022

The aim of the work was to study the impact of drought on the millet (Panicum miliaceum L.) seed germination and morphological parameters of seedlings and to identify millet genotypes with balanced rhizo- and organogenesis under arid conditions. Since the soil drought weakens plant immunity during seed germination and provokes development of various diseases, especially smut (Sorosporium destruens (Schlecht) Yanki), it is necessary to identify plant genotypes with high resistance to virulent smut races. We studied resistance of 28 millet varieties to 13 smut races registered in Ukraine. The osmotic PEG 6000 (23 %) was used to simulate soil drought during the seed germination. After six days of incubation, seed germinability was assessed and the length of shoots and roots of seedlings was measured. The stress resistance of millet varieties was evaluated by the root length/shoot length ratio (R/S). Water deficit in the soil decreased seed germinability to 50.12 %. Morphological changes were more pronounced in shoots (decrease in length by 77.3 %) than in roots (decrease by 37.7 %). Under favorable weather conditions, the rhizo- and organogenesis in seedlings was even (R/S=0.75±0.02). In case of soil drought, the ratio R/S dropped to 2.19±0.03. Most of the varieties were resistant to smut races Rs 1, Rs 5–Rs 7, and Rs 9–Rs 11; in addition, around 10 % of the studied varieties was highly resistant (9–8 points) to smut races Rs 2, Rs 8, Rs 12, and Rs 13. Millet genotypes resistant to Rs 3 smut race were not found. Thus, the varieties with R/S ratio around one and higher should be considered the most valuable genetic material in selection for drought resistance. High R/S ratios were observed in the varieties Zapovitne (1.77), Zolushka (1.54), Olitan (1.4), Skado (1.79) and Danilo (1.79). The varieties Olitan and Danilo were highly resistant to the smut races Rs 1, Rs 4, Rs 7, Rs 9–Rs 11, while the varieties Novokyivske 0.1 (2.17) and Konstantynivske (2.22) to the smut races Rs 1, Rs 4–Rs 7, Rs 9–Rs 12. The variety Bila Altanka was not affected by the most virulent smut races Rs 2, Rs 8 and Rs 13. We recommend to include these millet genotypes in selection for drought and smut resistance.
EFL Students’ Perceptions of Online Flipped Classrooms during the Covid-19 Pandemic and Beyond
Authors: Hung Luu Nguyen Quoc
Published: October 2022

The online flipped classroom has been a growing trend in education, particularly since the Covid-19 pandemic, and now, in the new normal, online learning has become the dominant alternative to traditional learning. In this model of learning, students can prepare new materials through reading or watching lesson videos at home, and then, in the physical or virtual classroom, they have time for active discussions. Although the flipped classroom model has been popular for several decades, the implementation of the flipped classroom in online-based teaching and learning in the context of teaching English as a foreign language (TEFL) has not been widely researched. In this study, an online questionnaire with both closed-ended and open-ended questions was administered to 120 EFL students at a public university in Vietnam, with the aim of understanding EFL students’ perceptions of online flipped learning. The results reveal that students have a relatively positive perception of online flipped learning, although a number of typical challenges can have a negative influence on the effectiveness of this type of instruction. Many suggestions for improving the online flipped classroom were also presented.

El estudio analizó el gasto público local y el efecto flypaper en los gobiernos locales de la región de Puno-2018, las transferencias intergubernamentales pueden causar dos efectos el efecto flypaper y la pereza fiscal, el efecto flypaper es considerado cuando las transferencias intergubernamentales pueden causar una expansión del gasto público local mayor que ante un aumento equivalente en los ingresos propios de la municipalidad. Para determinar la existencia del efecto flypaper se estimó el modelo de gasto local en función a variables fiscales. Los resultados demuestran la existencia del efecto flypaper en los municipios de la región de Puno, el flypaper por la suma total de transferencias que recibe las municipalidades es de 0.74%, según el rubro canon el flypaper es 0.25% y del foncomun es 0.33%. Esto indica que ante un incremento en las transferencias del canon y foncomun el gasto local aumenta en 0.34% y 0.41% respectivamente, pero ante la misma proporción de incremento de los ingresos tributarios el gasto local aumenta tan solo en 0.09%, estos resultados demuestran que la expansión del gasto local es mayor ante las transferencias y esto comprobaría que los municipios prefieren proveer viene públicos con transferencias que con los ingresos tributarios.

Published: October 2022

In the implementation of learning and education, facilities and infrastructure are very important. The existence of management of facilities and infrastructure in educational institutions will be maintained and its use clear. If the existing facilities and infrastructure are inadequate, the implementation of the learning process in schools can be hampered and not run well. Vice versa, if the facilities and infrastructure are complete and supportive, they will be able to facilitate the learning process, because complete facilities and infrastructure will provide variations in the learning process. This study aims to determine how the management of facilities and infrastructure in improving the quality of learning at the Madrasah Tsanawiyah Ibnu Sina Karawang. It is carried out with a qualitative descriptive approach which is carried out by analyzing, describing, and summarizing various conditions obtained from a collection of information obtained from field interviews or direct observations regarding the problem in question. In managing facilities and infrastructure, MTs Ibnu Sina Karawang has implemented planning, procurement, and management of facilities and infrastructure. However, the condition of the facilities and infrastructure at MTs Ibnu Sina Karawang is still very minimal, with the condition of the rooms being lightly damaged and some heavily damaged, there is a leaky classroom roof, there is no library and laboratory space and the condition of the benches and tables are damaged. This is because there are still limited funds and budgets, and the number of students can be considered quite small. the existing funds are not sufficient to cover the costs in the management of facilities and infrastructure.

Authors: Mubtadi Novendi Arkham
Published: October 2022

Salah satu faktor yang dianggap mampu mempengaruhi efisiensi penyaluran zakat adalah tata kelola zakat Dua indikator tata Kelola zakat yaitu jumlah dewan (board size), dan komposisi profesional dalam dewan (professional on board). Penelitian ini menggunakan pedoman zakat internasional yang baru diluncurkan tahun 2016 lalu yaitu zakat core principles, sehingga diharapkan mampu menutupi kelemahan penelitian sebelumnya serta memberikan kemanfaatan bagi stakeholder karena dianggap relevan dengan konsep akuntabilitas yang termuat dalam sharia enterprise theory. Penelitian ini merupakan penelitian empiris menggunakan sampel jenuh yang diambil dari 5 Organisasi Pengelola Zakat (OPZ) di Kota dan Kabupaten Pekalongan dengan periode pengamatan dari tahun 2016–2020 sehingga unit analisis berjumlah 25. Data diperoleh dari laporan tahunan masing-masing OPZ. Hasil analisis regresi menggunakan program Microsof Excel 2016 diketahui bahwa board size dan professional on board berpengaruh terhadap efisiensi penyaluran zakat. Oleh karena itu, OPZ seharusnya lebih memperhatikan masalah tata kelola zakat khusunya dalam mempertimbangkan jumlah dewan dan jumlah profesional dalam dewan sebagai alat untuk mencapai efisiensi penyaluran zakat. Keterbatasan dari penelitian ini adalah jumlah sampel yang sedikit yaitu hanya lima OPZ di dua kabupaten’kota serta periode pengamatan yang hanya 5 tahun. Penelitian selanjutnya diharapkan menambah data cross section maupun time series sehingga data yang dihasilkan lebih akurat.

Recykling zużytych modułów fotowoltaicznych metodami mechaniczno-termicznymi
Authors: WAHMAN Mustapha , SUROWIAK Agnieszka
Published: October 2022

Instalacje fotowoltaiczne stały się bardzo popularnym rozwiązaniem na przestrzeni pierwszego dwudziestolecia XXI wieku.Spowodowane to było głównie rosnącym zainteresowaniem przemysłu i rządów poszczególnych państw dotyczącym skutków i kwestiiłagodzenia - zmian klimatycznych, potrzeby dekarbonizacji, jak również rosnącym zapotrzebowaniem na energię. Najbardziejpowszechnym problemem związanym z panelami fotowoltaicznymi (PV) jest to, że ich żywotność jest ograniczona, co powoduje, żeostatecznie będą musiały zostać wycofane z eksploatacji. Wraz z rozwojem mocy produkcyjnych PV na całym świecie, w przyszłościbędzie generowana duża ilość odpadów związanych z panelami fotowoltaicznymi. Ponieważ panele fotowoltaiczne zawierają metaleciężkie, takie jak ołów, kadm i cyna, może to mieć znaczący wpływ na środowisko naturalne. Ponadto, odpady te zawierają równieżcenne metale (np. srebro, gal, ind i german) oraz standardowe materiały (np. aluminium, szkło), które po odzyskaniu stanowią cenneźródło tych surowców. Oczekuje się, że opracowanie zrównoważonego, przyjaznego dla środowiska procesu recyklingu i maksymalizacjaodzysku komponentów z paneli fotowoltaicznych pod koniec ich życia rozwiąże problem odpadów fotowoltaicznych. W tejpracy zbadano trzy alternatywne metody recyklingu krzemowych paneli fotowoltaicznych (mono/polikrystalicznych) w oparciuo połączenie procesów mechanicznych i termicznych. Trzy metody odzysku polegały na wykorzystaniu kruszarki młotkowej, po którejzastosowano obróbkę termiczną i klasyfikację na sicie kwadratowym, kruszarki nożowej typu schredder, a następnie obróbkę termicznąi klasyfikację na sicie kwadratowym oraz obróbkę termiczną, po której następuje klasyfikacja na sicie szczelinowym. Przeprowadzonoanalizy otrzymanych produktów za pomocą dyfrakcji rentgenowskiej (XRD) i fluorescencji rentgenowskiej (XRF) w celuoceny efektów odzysku. Wyniki wykazały, że obróbka cieplna, a następnie zastosowanie sita szczelinowego jest najskuteczniejsząmetodą bezpośredniego odzyskiwania szkła dla wszystkich badanych typów modułów fotowoltaicznych.
