Authors: Fuza Ângela Francine , Menegassi Renilson José
Published: February 2025

Neste estudo, a ordenação e a sequenciação de perguntas na leitura do gênero discursivo Panfleto Institucional, como proposta de aplicação no 6.º ano do Ensino Fundamental, são discutidas, destacando-se a forma como auxiliam o aluno-leitor na sua produção de sentidos. Para isso, o trabalho centraliza-se nas perspectivas sobre leitura, com ênfase nos estudos da Linguí­stica Aplicada e da prática de ordenação e de sequenciação de leitura, discutida por Solé (1998) e ampliada por Menegassi (2008; 2011; 2016), que destacam a relevância dessa proposta como parte do processo de desenvolvimento do leitor na escola. Como resultado, têm-se a ordenação e a sequenciação de perguntas para o gênero eleito, permitindo ao aluno: (1) extrair significados e atribuir sentidos ao que lê; (2) estabelecer o elo entre linguagem verbal e não verbal; (3) posicionar-se diante da temática do texto; (4) produzir um texto como réplica/contrapalavra; (5) realizar inferências e produzir sentidos.
O que diz o egresso de um curso de Letras sobre sua formação: argumentação em discursos sobre o ensino superior
Authors: Souza Gilton Sampaio de , Costa Rosa Leite da , Moreira Marí­lia Cavalcante de Freitas
Published: February 2025

Neste trabalho, analisamos, em respostas de egressos de Letras, aspectos do processo argumentativo em discursos sobre a formação que lhes foi oferecida e sobre o próprio curso. Focalizamos a construção argumentativa do discurso, as teses, as técnicas argumentativas empregadas e o auditório a que se dirigem os oradores. O corpus é constituí­do por dez respostas coletadas por meio de questionários escritos, aplicados a egressos de diferentes turmas de formação, que foram analisadas adotando-se uma abordagem qualitativa de pesquisa. A fundamentação teórica é advinda da Nova Retórica, de Perelman e Olbstrects-Tyteca (2014) e de Perelman (1993), com as contribuições de autores da área (ABREU,1999; IDE, 2000, dentre outros). Os resultados apontam que: a) as teses sobre a formação oferecida se constroem por associação e por dissociação de noções, em que a formação no curso se revela produtiva com professores que estimulam a pós-graduação, por exemplo; e b) as teses defendidas sobre o curso constituem-se prioritariamente por associação de noções, em que predominam os argumentos por interação ato-pessoa na valorização do curso. A conclusão da pesquisa apresenta teses sobre o curso e a formação oferecida em que os argumentos que se baseiam na estrutura do real se sobrepõem, sobretudo na interação ato-pessoa, revelando o lugar da qualidade e da pessoa como superior na hierarquia dos valores.

Authors: Adelino Francisca Janete da Silva , Nascimento Erivaldo Pereira do
Published: February 2025

Este trabalho analisa o funcionamento semântico-argumentativo da modalização deôntica na construção do gênero entrevista de seleção de emprego. Intentamos saber (i) quais recursos linguí­sticos instauram a modalização deôntica em entrevistas de seleção de emprego; e (ii) como esses modalizadores funcionam estrategicamente para gerar orientação argumentativa durante o processo interativo. Para isso, lançamos mão dos pressupostos da semântica argumentativa, em diálogo com os estudos da modalização desenvolvidos por Castilho e Castilho (2002), Neves (2011), Nascimento (2010), Nascimento e Silva (2012), entre outros. A investigação assume uma abordagem qualitativa e um caráter descritivo de base interpretativa, já que identificamos e interpretamos os modalizadores deônticos presentes no gênero entrevista de seleção de emprego, atentando para o seu funcionamento argumentativo. O corpus é constituí­do por vinte e duas entrevistas de seleção de emprego gravadas, coletadas em um Centro Universitário localizado em Natal-RN. As análises revelam que, durante o processo interativo, entrevistadores e entrevistados fazem uso de quatro tipos de modalizadores deônticos: deôntico de obrigatoriedade, deôntico de possibilidade, deôntico de proibição e deôntico volitivo. Ademais, os interlocutores constroem pontos de vista, crenças e pensamentos que compõem o ambiente social do qual fazem parte. Cada modalizador deôntico compreende uma orientação argumentativa e apresenta nuances axiológicas que variam de acordo com o posicionamento ocupado pelo locutor. Tal orientação compõe a teia argumentativa que constitui o gênero entrevista de seleção de emprego.

Authors: Gehrke Nara Augustin , Cabral Sara Regina Scotta
Published: February 2025

Abordando a produção textual como um complexo processo cognitivo (FLOWER; HAYES, 1981) e os gêneros segundo a proposta de Martin e Rose (2008), desenvolvemos o projeto "Um novo olhar sobre nossocotidiano", uma experiência pedagógica com a leitura e a produção de microcrônicas verbo-visuais, objetivando melhorar qualitativamente os textos com a reescrita. O gênero microcrônica verbo-visual tem o propósito sociocomunicativo de partilhar uma impressão pessoal sobre um tema considerado relevante socialmente, a partir do que o cronista interpreta da representação dos significados atinentes ao cotidiano representados em uma imagem fotográfica. Fizeram parte do projeto cinco turmas de semestres iniciais de cursos de graduação de uma universidade pública do interior do Rio Grande do Sul, ao longo de três anos. Nesse projeto, demos especial atenção à reescrita baseada na leitura de três participantes: o aluno-cronista, o professor, através de bilhetes orientadores, e os pares/colegas, através de avaliação holí­stica e protocolo de leitura crí­tica. Os resultados apontaram para a revisão colaborativa como prática promotora não só da qualificação dos textos, mas também de um engajamento mais efetivo dos estudantes na produção textual.
As listas e o efeito de apagamento enunciativo nos livros didáticos de filosofia
Authors: Sardá Daniela Nienkötter
Published: February 2025

O presente artigo discute a questão das listas – fenômeno ainda pouco estudado no campo das Ciências da Linguagem –, destacando sua utilidade como ferramenta de análise de discursos. Já na introdução, apresentamos o quadro teórico da análise comparativa de discursos, domí­nio que norteou nossa pesquisa de doutorado, da qual as análises aqui expostas são oriundas. Em seguida, na seção 2, apresentamos o estágio atual do estudo das listas, partindo dos estudos de Paveau e Rosier (2009) e Rabatel (2013). A seção 3, por sua vez, é dedicada à apresentação de algumas noções mobilizadas na análise das listas, a saber as noções de ponto de vista (PDV) (RABATEL, 2016 [2008], 2011a), posturas enunciativas (RABATEL, 2016 [2007], 2015, 2006), responsabilidade enunciativa (RABATEL, 2016 [2008]; VION, 2011) e apagamento enunciativo (PHILIPPE, 2002; VION, 2001). Na seção 4, apresentamos as análises propriamente ditas. Mostramos, com base num corpus de livros didáticos de filosofia publicados recentemente no Brasil, como seus autores se servem das listas para, de certa forma, apagarem-se de seus discursos, criando uma distância entre eles mesmos e suas afirmações. Ao final do artigo, na seção 5, discutimos como essa "estratégia" de apagamento enunciativo – entre aspas, pois nem sempre se trata de uma atitude consciente – está ligada à cultura pedagógica do enciclopedismo, ainda bastante recorrente nos livros didáticos de filosofia no Brasil.
Kesehatan Mental dalam Perspektif Islam dan Barat
Authors: Jannah Miftahul
Published: February 2025

Mental health is a crucial aspect of human life that determines psychological, social, and spiritual well-being. This study analyzes mental health from two main perspectives: Islam and the Western. The Islamic perspective emphasizes balance between physical, psychological, social, and spiritual aspects, with religious values as the fundamental foundation. The concept of jiwa takwa plays a key role in shaping mentally healthy individuals, where inner peace is achieved through worship, zikr, and surrender to the Divine. On the other hand, the Western perspective tends to refer to modern psychological theories that emphasize a scientific approach, defining mental health as a state free from psychological disorders, the ability to adapt to the environment, and the optimization of one’s potential. This approach relies on more empirical measures, such as emotional well-being, cognitive stability, and effective social functioning. Despite their differences, both perspectives highlight the importance of mental balance and individual quality of life. Integrating religious values with modern psychological approaches can provide a holistic solution for understanding and fostering more comprehensive mental health.

Authors: Priyanto Priyanto , Ningsih Arum Gati , Nurfadilah Nurfadilah
Published: February 2025

Writing scientific arguments is an essential skill in higher education, yet first-year students often face difficulties in constructing systematic and evidence-based arguments. This study aims to analyze the application of the Claim, Evidence, Reasoning (CER) framework in learning to write scientific arguments in higher education. Using a descriptive qualitative approach, this study involved first-year students in a series of learning activities to write scientific arguments using the CER framework. Data were collected through analyzing students' argument texts and classroom observations. The results showed that the CER framework helped students to develop claims that were more specific and based on real problems. In addition, students are also able to select and cite relevant evidence from trusted sources, and develop logical reasoning in linking evidence to claims. However, there are still challenges in finding and evaluating the credibility of sources, as well as in constructing explicit reasoning. Therefore, learning reinforcement strategies, such as interactive discussions, independent practice, guidance in finding credible sources, and individualized feedback are needed to increase the effectiveness of the CER framework in learning academic writing. This study confirms that the CER framework is an effective approach to improve students' critical thinking and academic writing skills.

Authors:   Altai State Agricultural University, Sadov Viktor V. , Sorokin Sergey A. ,   Altai State Agricultural University
Published: February 2025

The article presents a study of the process of loading a shredder with an auger
feeder with the possibility of regulating the feed and the effect of feed on the main output parameters. The factors influencing the operation process of the shredder together with the feeder are
determined, and a model for controlling the operation of this system is compiled. A direct-flow line
for grinding grain components was designed and manufactured, with which experimental studies
were conducted. A program for controlling the process of dosing grain material has been devel- oped. Experimental dependences on the effect of specific energy consumption on productivity and
average particle size when changing the material supply to the shredder are obtained. These results
will allow us to obtain the required grinding module with the lowest energy consumption and the
possibility of regulating the module during the grinding process through the control of the feeder
using software.

Peptides isolated from fish protein hydrolysates can be used in food systems as
functional ingredients of specialized food products. A study was conducted to determine the fractional composition and amino acid sequence of the protein of the pink salmon innards. The crushed
innards of chilled pink salmon were used as an object of research. Extraction methods based on the
use of ammonium sulfate were used to isolate proteins. The amino acid sequence in a peptide was determined by mass spectrometric method. Two protein fractions were isolated in the chilled pink
salmon innards. The amino acid sequence of fraction 1 was 194 amino acids, and fraction 2 was
134 amino acids. The sequences contain certain repetitive amino acid motifs, in particular CC, EE,
YY, VV, PP, AA, LL, NM, PPE, CYR and others, indicating the presence of structural or functional
areas in the protein composition that may have significant biological effects with target cells. For
further isolation and identification of biologically active peptides from amino acid sequences of
protein fractions, it is advisable to carry out a predetermined prediction of protein hydrolysis (in
silico) followed by peptidomic analysis based on mass spectrometry. It will allow monitoring the
content of already known peptides in fractions, but at the same time using it as a tool for the discovery of new bioactive peptides.

Studies have been conducted to predict the physico-chemical characteristics and
indicators of medicinal chemistry of a hypocholesterolenic food peptide responsible for its distribution, bioavailability and metabolism. The synthesized new hypocholesterolenic peptide with the
amino acids sequence of CHAECGAACKEFCLEG was used as an object. The predicted molecular
weight of the peptide is 1 669.64 Da. The actual value of the synthesized peptide is 1 670 Da, which
indicates that the synthesized peptide meets its predicted characteristics. The peptide is lipophilic,
has optimal pharmacokinetic and safety profiles. The index of pKa is 1,382 units and lower than
the base (5,199 units) by 3.76 times, which indicates a high bioavailability of the peptide. Analysis
of molecular descriptors: the proportion of carbon atoms sp3
(Fsp3
) is 0.771 units with an optimal
value of more than 0.43 units, which indicates weak colloidal aggregation, high bioavailability. The
studied peptide is well soluble in biological fluids, is in an unbound state, does not form colloidal
aggregation, and is able to reach target cells, which indicates its bioavailability and high biological
efficiency.

Carrying out agrotechnical operations at various agrofons and transporting ag- ricultural goods across fields and field roads is accompanied by the impact on the soil cover of
wheeled and tracked tractors, combines, trailers and other technical means involved in the techno- logical process of cultivation and harvesting of crops. The interaction of the movers with the soil is
accompanied by its deformation by the contacting working elements of the movers, which signifi- cantly affects the resistance to movement of the agricultural unit. To assess the ability of the soil to
resist deformation, a number of dependencies are proposed, based on a pattern that estimates the
amount of soil deformation from the applied load when a stamp of various sizes is pressed into it.
A number of factors influence the deformation of the soil when exposed to a mover: the type of
soil, the thickness of the fertile layer, the presence or absence of a turf layer intertwined with the
root system of plants, the presence or absence of a dense clay sub-arable base, soil moisture, its
structure, other factors. When assessing the ability of the soil to deform under the load caused by
the immersion of agricultural machinery movers into it, it is difficult to take into account the influence of all factors involved in this process. However, it seems possible to assess the stress state of
the soil during the introduction of deformers into it by analyzing some indicators that change as the
depth of the introduction of the deformer increases, as well as analyzing the intensity of changes
in these indicators. This article attempts to obtain a dependence that comprehensively reflects the
influence of soil conditions on the resistance to indentation of the movers and also provides some
results of research aimed at developing such a dependence.
The use of sterile A2 cytoplasm in breeding of hybrids F1 of sugar sorghum
Authors:   Russian Research and Design-Technological Institute of Sorghum and Corn, Kibalnik Oksana P.
Published: February 2025

One of the promising crops with multipurpose use in various branches of the
agro-industrial complex is considered to be sugar sorghum. The creation of hybrids based on different sources of sterility will expand their genetic diversity and increase biomass productivity due
to the effect of heterosis. The aim of the research was to study sugar sorghum hybrids based on A2
cytoplasm according to the main breeding characteristics. Hybrids were tested in comparison with
the standard varieties Volzhskoye 51, Flagman during 2022–2024 at the experimental field of the
Russian Research and Design-Technological Institute of Sorghum and Corn. Hybrids of the first
generation were obtained with the participation of CMS-lines A2 KVV114, A2 Chaika (female
form) and cultivars k-64, k-10832, k-54, k-5529, k-581 (paternal form) from the collection of the
N. I. Vavilov All-Russian Institute of Plant Genetic Resources. Studies have shown that the isolated hybrids A2 KVV 114/k-10832 and A2 KVV 114/k-54 are recommended for use as succulent
feeds due to the powerful development of the leaf apparatus (upper and middle tier), biomass yield
and average sugar content in the stem juice. The advantage over standard varieties was revealed
in the range of 7.8–67.9% for a number of basic breeding characteristics (plant height at maturity,
flag-leaf area, number of leaves, biomass yield). In addition, the A2 KVV 114/k-54 hybrid had
an excess over the standards of Volzhskoye 51, Flagman in terms of the largest leaf area, which
ranged from 43.0 to 72.4%. Thus, the results of the scientific work indicate the expediency of involving sterile cytoplasm of A2 type in breeding programs for the breeding of productive hybrids
sugar sorghum.

Reduction of losses in the process of grain production is the most promising direc- tion for meeting the to meet the needs of the population for food. It was revealed that grain losses
are significantly affected by production technologies, the level of which depends on the economic
development of countries. Minimal grain losses, about 5%, during post-harvest processing and
storage occur with high technologies, which are used mainly in industrial countries. At the same
time, grain losses in developing countries amount to about 20%. Under unfavorable conditions, for
example, when waiting for wet grain to be processed on threshing floors, losses can reach 30–50%.
The aim of the research is to analyze the conceptual technological provisions for minimizing loss- es and maintaining grain quality during its post-harvest processing and storage. The main research
method included retrospective and system analysis of technological processes of post-harvest
grain handling of main cereal crops, as well as biotic and abiotic factors affecting grain quality and
its safety. The change in grain quality during its post-harvest handling, which was characterized
by internal and acquired properties, was considered. The parameters of grain quality deterioration
during post-harvest handling and storage, the role of aeration and drying in maintaining quality
were discussed. Particular attention was paid to the need for a thorough analysis of the effect of
the drying method on grain quality when developing a grain drying strategy and post-harvest han- dling. The presented schemes of the design features of a storage facility for safe storage of seeds
in bags and a system for monitoring grain mass in bulk are scientifically significant and can be
applied in design bureaus developing technologies and machines for grain handling and storage.

There are two subspecies of the Siberian cisco (Coregonus sardinella) in Yakutia,
the East Siberian vendace and the Yakut shallow-water cisco. The East Siberian vendace from the
Ust-Yansky district has been studied. The results of the study of the East Siberian vendace meat
showed that it has a high nutritional value, the protein content was 15%, fat – 9%. The value of the
East Siberian vendace meat is primarily due to the content of high-grade protein. The results of the
biological value assessment analysis showed that the East Siberian vendace proteins exceed the
protein value of an ideal protein in terms of the biological value of essential amino acids. The East
Siberian vendace fat contains polyunsaturated fatty acids. Consequently, the East Siberian vendace
fillets are valuable raw materials for the production of fish pates. The blueberry supplementation
improves organoleptic characteristics, increases the flavor of the pate. The purpose of the work is
to design the technology of fish pate made from the East Siberian vendace with blueberries. The
average yield of fillets was taken as 62%, flank - 16%. The work uses generally accepted organo- leptic, physico-chemical, microbiological methods for determining the mass fraction of water, fat,
proteins, minerals, vitamins in fish, blueberry and pate. The modes and duration of technological
processes for the production of pate have been developed, which ensured the quality of the finished
product. The quality indicators of the pate were experimentally determined, and a comprehensive
assessment of the nutritional value of pate was given. The pate quality analysis data showed that
the product meets safety requirements and has high nutritional value and excellent consumer prop- erties. Based on these studies, technical documentation for fish pates with blueberries has been
developed.
Calculating the power of an internal combustion engine with a Common Rail fuel system when operating in free acceleration mode

Published: February 2025

A new methodology of calculating the power of an internal combustion engines
(ICE) in free acceleration mode, based on the assessment of reactions occurring on its supports is
proposed. Experimental studies were carried out on the YAMZ-53445-22 internal combustion engine with a set of installed measuring equipment. The operation of the internal combustion engine
was carried out in free acceleration mode from minimum to maximum crankshaft speed on all cyl- inders and with one disconnected cylinder. At each operation mode of the internal combustion en- gine, the crank-shift rotation speed, the value of reactions of the supports and the indicator torque
were measured, after which the reactive torque and engine reactive power were calculated. As a
result, it was found that the maximum value of the indicative power of the internal combustion en- gine, calculated by the built-in diagnostic system in relation to the cycle fuel supply, was observed
at the crankshaft speed from 2 648 to 2 700 min-1 and was 70,3 kW when operating on all cylinders
and 80.6 kW when operating with one disconnected cylinder. The highest value of reactive power
was achieved when the internal combustion engine was running on all cylinders and was 40 kW
at crankshaft speed 2 697 min-1. Disconnection of one of the cylinders led to a decrease in the reactive power of the internal combustion engine to 25 kW at the crankshaft speed of 2 591 min-1.
The experimental studies have shown that it is possible to estimate the power performance of the
internal combustion engine by the value of reactions of its supports in free acceleration mode. The
nominal effective power by the proposed method can be determined only at additional loading of
the internal combustion engine, for example, by the forces of resistance.

The modern level of mechanization of agricultural enterprises with large land areas
in their turnover is characterized by the presence of a significant number of wheeled energy-saturated semi-frame tractors of 5–8 traction class. The use of tractors of this class on small-contour
fields of the central and northern agricultural zones of the Amur region, characterized by the significant presence of slope fields with a slope angle of more than 5 degrees, does not correspond to
the parameters of efficiency and safety. It should also be noted that small peasant farms also play
a significant role in the production of agricultural crops in the Amur region, while the volume of
products produced by them is up to 28 % of the total gross crop production in the region. At the
same time, it is noted that most of the small-scale fields of the region belong to and are cultivated
by the farms. The need for their processing is reflected in the formation of machine and tractor
parks of this category of farms. What determines the use of tractors of class 1.4–2 for agricultural
work, while their technological characteristics require improvement through the introduction and
application of new technical solutions. The article deals with the issues of forming the performance of a promising wheeled machine-tractor unit equipped with a loading-stabilizing device,
the novelty of which, the inventive level and industrial applicability are confirmed by a patent of
the Russian Federation for the result of intellectual activity. An original mathematical apparatus is
proposed that contributes to the calculation of the efficiency of the machine-tractor unit. It is established that the installation of the device of the proposed design in the running system of the unit
is able to increase the working speed both during field work and during movement along transport
routes, reduce slipping, increase the utilization factor of shift time.

Currently, honeysuckle is very popular in the gardens of the Amur region. Breeding work to create varieties of honeysuckle with a high content of biologically active substances
is actively underway in the Far Eastern State Agrarian University. The paper presents data on the study of the chemical composition of honeysuckle berries of 4 varieties and 7 prospective hybrids.
The largest berry was a hybrid of 4/3 (Slivovaya) and 29/5 (Bananovaya), the weight of 100 berries
was 95.2 g and 128.9 g, respectively. The F-12 and F-13 hybrids were the most productive. The
highest sugar content was observed in hybrids 29/5 (Bananovaya), F-13, F-14 and F-15 and was
at the level of 13–13.7 %. Titrated acidity in terms of malic acid among the selective hybrids of
honeysuckle varied from 0.56 % (F 14) to 1.56 % (F-17). Prospective hybrids 29/5 (Bananovaya)
and F-12 had a higher ascorbic acid content (76.7 mg/100 g) compared to other hybrids. Honeysuckle is a source of flavonoids, the structure of which has been identified by IR spectroscopy. IR
spectra of flavonoids of berries of hybrids F-13, F-15, 29/5 (Bananovaya) and varieties Podarok
Amurchanam, Stepanovskaya 1 are similar to the IR spectrum of quercetin.

The problem of metabolic disorders in the human body, causing obesity and diabetes mellitus, is relevant. An alternative way to prevent and treat these diseases is the use of combined synergistic biologically active agents. Sea buckthorn oil is a natural source of essential and unsaturated fatty acids and other bioactive compounds. Sea buckthorn seeds are characterized by a unique combination of omega-3, 6, 7, 9 fatty acids with anti-toxic and cardio-protective properties.
The soft part of the berry and the peel of sea buckthorn is one of the few vegetable sources with a
high content of omega-7 monounsaturated fatty acid (43 %), which regulates lipid-carbohydrate
metabolism in the body. It is known that probiotic microorganisms play an important role in the
prevention and correction of lipid metabolism. In general, studies on the effect of polyunsaturated
fatty acids of sea buckthorn oil on probiotic microorganisms are limited. Therefore, sea buckthorn
oil and pure cultures of bifidobacteria Bifidobacterium longum DK-100 were chosen to create a
multifunctional dietary supplement. In this paper, the effect of polyunsaturated fatty acids of sea
buckthorn oil on the biochemical activity of bifidobacteria was studied. The most favorable concentration of sea buckthorn oil of 3 % was found to increase the number of bifidobacteria cells
during cultivation. It has been proved that the storability of the bacterial concentrate is prolonged
in the presence of sea buckthorn oil. The viable status of bifidobacteria cells is hundreds of billions
cells in 1 cm3. Probably, polyunsaturated fatty acids of sea buckthorn oil are included in bacterial
cell metabolism as a component of membrane phospholipids and storage substances.

Knowledge of potential pest risks is essential for soybean disease control planning.
The purpose of this study is to obtain actual information about the patterns of the spread of diseases in soybean fields in the Amur region, as well as the influence of various factors, such as wild
vegetation near the field, weather, etc. The author shows the results of field and laboratory studies
from 2019 to 2022. The distribution and density of soybean diseases in different areas of the Amur
region and the species composition of soybean diseases were studied. Mathematical processing of
the obtained data was carried out by the method of calculating the Euclidean metric. Clustering of
local lists of types of fungal diseases was performed on the basis of the obtained calculations. The
most common disease is septoriose (Septoria glycines). The rarest disease is sclerotiniose (Sclerotinia sclerotiorum). A new disease for the territory of the Amur region was discovered: soybean
stem cancer (Diaporthe phaseolorum var. caulivora). The pathogen agent weakens the plant, so
fusarium becomes diffuse form and causes tracheomycosis wilt of soybean plants. The dependence
of the density and spread of soybean diseases on the following factors was revealed: the composition of the adjacent wild plants, the degree of isolation of the field, and local weather conditions.
The degree of isolation and quarantine measures have the greatest influence on the spread of cercosporosis (Cercospora sojina). Powdery mildew (Erysiphe communis) is highly sensitive to local
weather and climate conditions. Septoriose (Septoria glycines) weakly responds to these factors.
Throughout the region, this disease is widespread and has a high density in soybean crops.

The article presents the results of three-factor experiment on corn crops of local
selection Birsu, Alitet 2, Guran 2 and hybrids of foreign selection Moldavskiy 215 SV, Р 7515,
Р 8521 and Р 7460, on different mineral nutrition backgrounds and two sowing dates in the conditions of Khabarovsk krai. The studies were carried out in 2021–2022 on the experimental field
of the Far Eastern Agricultural Research Institute. The soil of the experimental section was meadow-brown, heavy loamy soil. The experiment was prepared in fourfold repetition. On average,
the growing season lasted approximately 108 days. The highest grain yield, up to 125.3 c/ha was
noted on the mineral nutrition background No.2 (N110P110K90) and No.3 (N130P130K90). Increased
dose of mineral fertilizers on background No.3 led to a slowdown in the onset of all phases of corn development by an average of 3–5 days in comparison to plants on backgrounds No.2 and No.1
(N90P90K90). In the conditions of Khabarovsk krai, the full ripeness of grain occured at the beggining of the first ten days of September in the varieties of selection of the Far Eastern Agricultural
Research Institute – Birsu, Alitet 2, Guran 2 and hybrid Moldavsky 215SV, while hybrids Р 7515,
Р 8521 and Р 7460 reached only wax ripeness during this period. It was noted that the greatest
influence on yield indicators and morpholobiological characteristics had varietal characteristics
(69.98 %) and the dose of mineral fertilizers (5.2 %), rather than sowing time (1.38 %). New varieties of local selection Alitet 2 and Guran 2 can be recommended for introduction into production
in Khabarovsk krai.

The analysis of the state of soil resources in organic agricultural production and
systems of their restoration is carried out. Seven factors affecting soil fertility from the point
of view of its restoration and improvement have been identified: the use of siderates, organic
fertilizers, precision farming systems; the implementation of scientifically based zonal crop
rotations; the technogenic impact of machinery and equipment on the arable layer of land; the
use of new varieties of grain crops taking into account zonal features; the management of technological processes for restoring and increasing soil fertility. Detailed attention is paid to the
consideration and development of technologies for the processing of liquid manure and the production on its basis of high-quality liquid and solid concentrated organic fertilizers (COE) using
biologically active additives (dietary supplements). The principles of constructing a system of
machines for the restoration of soil resources are substantiated. The technological characteristics of the basic machines for the production of solid manure are given: a mobile installation
for the local treatment of liquid manure with a capacity of up to 45 m3
/h for the initial manure;
a shoulder agitator with equipment for dosing the application of dietary supplements with a
capacity of up to 400 t/h; a machine for the introduction of solid COE with a pneumocentric distributing working body for their surface application with doses up to 4 t/ha. The basic machine
for the preparation and application of liquid COE is a mobile unit based on the LFM type with
autonomous equipment for mixing dietary supplements with liquid manure and liquid fraction
of manure and application with doses from 1 to 4 t/ha. The use of liquid and solid COE with
small doses of application allows not only to improve the condition of the productive soil layer
according to biochemical parameters, but also to recoup the costs of their production with the
resulting addition of grain and fodder crops.

The development of technologies and means of harvesting grain crops contributes to an increase in the level of mechanization of work, labor productivity, the quality of
threshing and a reduction in harvesting time, but they all have specific drawbacks. This is due
to the fact that the development of technologies is carried out without the use of innovations
that are fundamentally different from traditional means. The article analyzes modern methods
and means of harvesting grain crops by various methods, identifies their main shortcomings. It has been established that most of the existing harvesting methods do not provide threshing of
grain crops in conditions of high soil moisture; in areas of fields with a large slope and difficult
terrain; and also have a significant force effect on the soil, leading to its overcompaction. An
equation for the variable performance of an unmanned aerial vehicle is obtained, as well as a
condition for the efficiency of its operation. The shift productivity of the vehicle was calculated
when harvesting grain crops, taking into account its carrying capacity, the yield of grain crops
and the distance of transportation of the spike part of plants to the threshing point. It has been
established that an increase in the distance of transportation of the ears of plants to the threshing
point leads to a decrease in the shift productivity of the unmammed aerial vehicle; an increase
in crop yields and carrying capacity leads to an increase in the shift productivity of the vehicle.
Taking into account the obtained theoretical results of the research, a layout diagram of a unit
for harvesting grain crops was developed on the basis of a standard unmanned aerial vehicle.

A brief description of the energy supply state in Nyurbinsky ulus is given. The article gives the gas fields information in Yakutia. It is noted that in the near future there are no
plans to connect the ulus to gas networks. The heating network in the villages there operates on
electric boilers. Since the 1970s, the power supply of the ulus has been provided by an electric
line of 110 kV, with a length of 394 km. Currently, emergency power outages have become more
frequent due to the high wear of wooden supports. The danger lies in the fact that if an accident
occurs in winter, then there is a threat of freezing of residential buildings, social infrastructure
and industrial buildings. To solve problem mentioned above, it is proposed to introduce pyrol- ysis technology for solid waste disposal in villages. By cleaning the environment from solid
waste, it is possible to obtain alternative fuel in the form of pyrolysis gas along the way. The combustible component in it is methane, similar in its parameters to natural gas. By conducting
pyrogas through a gas generator, there’s a possibility to obtain electrical energy and, thus, create
an autonomous electric station.
