Published: February 2025

The purpose of the study is to generalize approaches to calculating the optimal
duration of grain crop sowing. The authors provided a historical chronology of the use of direct operating costs, cumulative and complete costs. Generally, researchers believed that crop losses from
delaying sowing operations were proportional to their duration, and from depreciation charges on
machinery were inversely proportional to optimizing the duration of sowing operations. However,
after the introduction in 2018 of the state standard regulating the economic assessment of agricultural machinery, all direct operating costs for machinery, including depreciation charges for
machinery, became constant in rubles per hour of operation of the machine and tractor unit and
do not depend on the duration of sowing operations. On the other hand, it is necessary to take into
account the costs associated with the maintenance of agricultural machinery, insurance payments
and loans. The authors gave examples of approbation. The simulation experiment for steam-treated wheat using normal technology for Siberia, depending on the choice of aggregates, shows a
probability of 2.5–9.5% failure to perform the operation within the specified agrotechnical time.
There is a calculation of the optimal duration of direct sowing of wheat in Siberia using the John
Deere 96 tractor and the John Deere 730 sowing complex using a formula based on the derivative
of total costs.

The article considers the possibility of using vegetable raw materials of the Far
East region in the production technology of a functional food product. The objects of the research
were the samples of guelder rose jelly with arabinogalactan. The recipe included various dosages of
guelder rose fruits – 10; 15 and 20 % by weight of raw materials (samples No. 1, No. 2, No. 3). The
amount of arabinogalactan in all formulations was 2.5 %. The technological production scheme of
«Guelder rose jelly with arabinogalactan» was developed. Based on the organoleptic analysis, sample No. 2 was selected for research, with the inclusion of 15 % of guelder rose fruits and 2.5 % of
arabinogalactan in the recipe. When determining the physical and chemical parameters the following values were obtained: the mass fraction of moisture was 67.61 %; mass fraction of titratable acids 1.6 %; the presence of impurities – was not detected. As a result of microbiological study it was
found that the studied parameters were within normal limits and met the requirements of regulatory
documents. The values of the amino acid composition indicated the presence of 14 amino acids in
the jelly, of which 8 amino acids were essential and 6 were non-essential. The study of the vitamin
composition determined the content of carotene, vitamin P (rutin), vitamin C (ascorbic acid) and
vitamin E in the content of 26.5; 116.8; 44.0 and 0.87 mg respectively. At the final stage of research
an analysis of hazards was carried out, critical control points were identified and preventive actions
were developed for each stage of the production process.

The influence of seed application rates and doses of mineral fertilizers in the zones
of soil fertility of the studied area on the water regime of the soil and the yield of spring wheat in
the conditions of the Altai krai is considered during field experimental studies. To select the optimal experimental parameters that ensure reliable data acquisition, a full-factor experiment was
implemented for three factors. Moisture reserves in the meter layer for each experimental site were
determined during the growing season. Based on the superimposition of graphical dependencies of
the amount of seeds, fertilizers and the yield obtained by soil fertility zones, the significance of the
studied factors was revealed and their rational combinations were established to ensure maximum
yield. It has been confirmed that the soil fertility zone has the most significant impact on the water
regime of the soil and the yield of spring wheat among the studied factors. The high efficiency of
the correct application of differentiated sowing and the application of mineral fertilizers has been
proven. For example, the range of yield changes was 28.6–41.5 c/ha.

The article presents the study of helminthofauna of the bears held in captivity in
Blagoveshchensk, the Amur region. A total of five animals of different ages were examined. The
search was carried out in autumn before hibernation and in the following spring after waking up
from hibernation. The bears’ feces were examined for the presence of eggs of nematodes, cestodes,
trematodes and oocysts of protozoa by a combined method. This method includes flotation using
a sodium nitrite solution with a density of 1.32 and sedimentation. Eggs of the nematodes Uncinaria skrjabini and Toxascaris transfuga were found. Eggs of trematodes, cestodes and protozoan
oocysts were not found. The extensiveness of invasion by uncinariae (U. skrjabini) was 100 %
with the intensity of invasion from 8 to 218 eggs per 1 g of feces. The extensiveness of invasion by
ascarids (T. transfuga) was rather low (40 %) with the intensity of invasion from 2 to 6 eggs. After
the examination and before hibernation the bears were dewormed with the drug containing fenbendazole at a dose of 34 mg/kg of the active substance once orally. After the winter hibernation which
lasted about 5 months, the following spring the authors performed the control ovoscopy of feces.
Uncinariasis and ascariasis were registered in all animals. After repeated deworming with the drug
containing albendazole at a dose of 15 mg/kg (once orally) it has been stated that the effectiveness
of deworming was 80 % in uncinariasis and 100 % in ascariasis. It has been recommended to develop a scheme of therapeutic and diagnostic measures aimed at increasing the effectiveness of the
fight against helminthiasis of the bears.

Published: February 2025

The process of harvesting soybeans by direct harvesting is a very energy-consuming process. The application of the method of combing plants on the root will partially reduce
energy consumption by reducing the working organs. It has been found out that modern combine
harvesters do not provide the quality of harvesting in accordance with agrotechnical requirements.
The results on the use of a combing harvester for harvesting soybeans by the method of combing
plants on the vine are presented. With a minimum level of losses behind the harvester (7.9 %),
optimal indicators of the technological process of harvesting soybeans by the method of combing
were determined. Based on the data of the experiment, a regression equation has been obtained
that adequately characterizes this process. An alternative version of the combing header is present- ed, which allows excluding the impact of the inertial component and leads to cracking of soybeans
before they break off from the stem and fly forward along the course of the tractor with the comb- ing header. In the future, it is possible to use a screw combing harvester for harvesting seed crops
with a row spacing of 30 cm or more.

As a result of the conducted studies, it was found that when green pear cuttings
were taken from uterine bushes in the first decade of June (June 07) and when the slices were
treated with the growth stimulant β-indolyl-3-butyric acid (IBA) (50 mg/l), the forms PG 12
(k), PG 17-16, PG 2 had the greatest degree of their rooting. The clonal rootstocks of pears
PG 12 (k), PG 17-16, PG 2 had the largest number of rooted cuttings. Without treatment with a plant growth regulator, the best results of rooting and the number of rooted cuttings were
characterized by the forms PG 12 (k), PG 17-16, PG 2. When treated with the plant this growth
stimulator (50 mg/l), green cuttings cut in the second decade of June (June 20) and subsequent
rooting allowed us to establish that the best indicators of rooting and rooted cuttings were PG 12
(k), PG 17-16, PG 2. Without the use of a plant growth stimulator, the forms PG 12 (k), PG 17-
16, PG 2 were characterized by the highest percentage of rooting and rooted pear cuttings. When
treated with the plant growth stimulator, the forms PG 12 (k), PG 17-16, PG 12, PG 2 had the
greatest length of increments and the greatest length of the root system. Without the use of a plant
growth stimulator, the forms PG 12 (k), PG 17-16, PG 12, PG 2 had the best result of the length
of the increments and the length of the root system. After taking green pear cuttings from uterine
bushes in the second decade of June (June 20) and when treating the slices with the plant growth
stimulant β-indolyl-3-butyric acid (IBA) (50 mg/l) and without treatment, the best forms were
PG 12 (k), PG 17-16, PG 12, PG 2. PG 12 (k), PG 17-16, PG 12, PG 2 were characterized by
the greatest length of increments, the length of the root system during treatment and without
treatment with a plant growth stimulator.

Published: February 2025

The tuber productivity of a variety is genetically determined by a number of char- acters and is adjusted by the impact of environmental factors. As a result of a comprehensive
agroecological assessment of the collection of domestic and foreign potato varieties in contrasting
agrometeorological conditions in 2014–2022, the variability of the value of the tuber productiv- ity trait, which characterized separately isolated genotypes according to the phenotypic value of
the trait, was studied with the imposition of additional ecological variation. The purpose of the
research is to identify the sources of increased potato tuber productivity in a comparative assessment of the studied assortment of domestic and foreign selection in the conditions of the Middle
Priamurye. The results of the field experiment were obtained and their statistical processing was
carried out. A variational analysis of the data was carried out. The sample volumes for each sample are given, the range of tuber productivity variation is established. The indices of variance,
standard deviation, error of the sample mean, coefficients of variation and evenness of the studied
quantitative trait, which by phenotypic value characterized the response of each studied genotype
to specific environmental factors, were determined and analyzed. As genetic sources of increased
tuber productivity from the Russian assortment of potatoes with a slight variability of the trait and
the value of the evenness coefficient, which is 83.1–95.1 %, the following varieties were selected
(t/ha): Lyubava (29.6); Kholmogorsky (28.6); Saprykinsky (27.4); Geyser (26.9); Krepysh (26.2);
Vasily (26.1) and Krasavitsa Bryanshchiny (25.6). From foreign varieties, samples with medium
and significant variability of the trait (75.1–87.1 %) can be considered (t/ha): Red Lady (29.2);
Rocco (28.0); Odyssey (27.1); Latena (27.7); Adretta (26.2) and Lugovskoy (26.2). With an average productivity of the Russian varieties over the years of study amounting to 25.8 t/ha, there was
established their benefit over foreign varieties with a yield of 23.6 t/ha.

Capercaillie meat is mostly used for personal consumption, which, in our opinion,
is explained by the termination of centralized procurement of meat products of game industry after
the break up of the USSR. But over the last years the wild meat market is beginning to restore and the opportunities for more detailed economic evaluation of game industry arise. The study presents
original data on estimation of abundance and game bag for capercaillie in Kirov region, as well as
the comparison with official data of the State Monitoring. It also contains the results of investiga- tion of weight characteristics of capercaillie in the area, upon which the production of capercaillie
hunting is estimated and expressed in monetary and physical terms. Safety of capercaillie hunt
food products is analysed according to literature data, and the possibility of obtaining additional
products is estimated.

Experimental modeling of oxidative stress is an important component of pharmacological studies at the preclinical stage. The article presents the results of approbation of the model of the impact of a low-frequency alternating magnetic field in comparison with the previously
proven model of the influence of high temperatures on a warm-blooded organism. For the experiment, 4 groups of laboratory animals were formed, 30–36 rats each. The advantages of the model
of oxidative stress formation under the influence of a magnetic field are confirmed by a more
pronounced accumulation of lipid peroxidation products in the blood plasma and liver tissue of
rats compared to intact animals and rats subjected to hyperthermia. The influence of the magnetic
field on rats was accompanied by a statistically significant excess of the level of diene conjugates
relative to intact rats by 17–21 % in blood plasma and by 36–43 % in liver tissue (p<0.05). The
concentration of lipid hydroperoxides under magnetic induction increased by 14–20 % in blood
plasma and 30–32 % in liver tissue compared with the intact group (p<0.05). More pronounced
dynamics was demonstrated by the secondary product of lipid peroxidation – malon dialdehyde,
the accumulation of which was statistically significantly higher in animals exposed to high temperatures. Thus, the advantages of the model of oxidative stress formation under the influence of a
low-frequency alternating magnetic field have been experimentally confirmed.

Based on the previously conducted analysis of the structural and technological
schemes of presses for obtaining a feed products, a structural and functional scheme of a press
for obtaining granular-briquetted mixtures based on root-grain compositions has been devel- oped. Earlier studies have made it possible to determine the dimensional characteristics, as well
as the physical and mechanical properties and indicators of the initial grain and root-tuberous
raw materials. It is established that the determining factors on which the final quality of the
resulting product (granules, briquettes) depends are the parameters of the operation of the final
element – the pressing-forming block of the press. The factors that have the greatest influence on
the process under the study are identified, and the levels of their variation for the implementation
of the proposed experiment planning matrix are determined. As a result of experimental studies
consisting of 15 experiments, regression analysis was carried out and the values of standard deviation, correlation and determination coefficients were obtained, the F-criterion was determined
and its significance values. Based on the mathematical processing of experimental data, mathematical models were obtained that adequately described the nature of the process of preparing a
homogenized-molded mixture at the final stage – in the pressing-forming block. The reliability
of the models was assessed by the significance level of the Fisher criterion, which was less than
0.05, which confirmed the significance of the models obtained. Mathematical processing of the
obtained models revealed areas of extreme values of factors: the angular velocity of the knife, the
length of the channel and the thickness of the briquette wall; at which the accepted optimization
criteria (uniformity, strength of granules and energy intensity) tend to the established optimal
value. A graphical interpretation of the obtained dependencies in the form of surfaces and their
sections is carried out, which allows us to visually assess how the change of each factor affects
the accepted optimization criterion when working with the pressing-forming block of the press.

Differentiated learning is learning that prioritizes and facilitates student needs according to student characteristics, one of which is learning readiness, which consists of groups ready for challenges, understanding concepts and repeated concepts. From these three groups, it will be analyzed how learning obstacles occur in analyzing the circle concept. This research is a qualitative descriptive study with 15 research subjects. Based on the results of data analysis, it can be concluded that the group of students who understand the concept and repeat the concept experience epistemological obstacles in understanding the relationship between the central angle and the circumferential angle, analyzing the area of a circle, analyzing the elements of a circle, and analyzing the relationship between the central angle and the area of the circle. Apart from that, students experience difficulty in representing the problems given because students are unable to find information and instructions from the questions given.

An increasing number of children in the United States are growing up in
multispecies families, where humans and companion animals form close
bonds and share daily life. A burgeoning body of work highlights the
significant role of animals in shaping developmental outcomes across a
wide range of domains. Few studies examine how children in multispecies
families perceive and construct their relationships in the context of
growing cultural sentimentalization of pets. Using narrative and visual
methods, we explored children’s perspectives on their relationships with
their companion animals. We recruited 24 parent-child dyads in the
United States (children aged 3-7 years). We interviewed parents, asked
children to draw and describe their favorite memories with their pets,
and interviewed children about their relationships with companion
animals. Using narrative and mapping procedures, our analyses revealed
three themes: children constructed companion animals as family members,
integrated them into daily activities, and attributed subjectivity to
them. Our findings highlight how children navigate complex relationships
with animals, providing implications for child development, empathy, and
the human-animal bond within multispecies families.

Abstract
The effective and damage-free removal of deteriorated paint and varnish from wood surfaces is vital for both aesthetic and long-term material use. Traditional methods like scraping or sanding are labor-intensive and time-consuming. Moreover, alternative solutions like paint strippers pose significant threats to human health and the environment. To address these challenges, this study introduces a groundbreaking solution: the Cabin Type Full Automation Paint Removal Machine (CAPREM), designed and manufactured. The CAPREM is engineered to efficiently eliminate layers of paint and varnish from diverse materials, including wood, by blasting abrasive media onto the surface using compressed air. With the ability to control and adjust parameters such as air pressure, nozzle diameter, removal angle, removal distance, and feed rate, the machine offers flexibility for various coating layer removal scenarios. Furthermore, by enhancing the diversity of abrasive media, the CAPREM aims to provide an environmentally friendly solution for coating layer removal, benefiting multiple industries and advancing research in this field.

The study assessed the effectiveness of scientific cultivation techniques for sesame using improved varieties GT-4 and GJT-5 during 2021–2022 in Anjar, Bhuj, and Nakhatrana talukas of Kachchh district, Gujarat, India. Conducted over 11.6 hectares through 29 demonstrations by ICAR-CAZRI and Krishi Vigyan Kendra, Bhuj, India. The demonstration trials addressed the region’s saline-alkaline sandy soils with pH levels ranging from 8.5 to 9.2 and significant nutrient deficiencies. Sesame was sown between mid-February and early March and harvested from late April to early May. Improved practices included using high-yielding varieties, seed treatment, timely sowing, line sowing, recommended fertilizer application, and integrated pest management. The demonstrations achieved a 17.18% increase in seed yield, with 941 kg ha-¹ compared to 803.5 kg ha-¹ from farmers’ traditional practices. Technological gaps of 300 kg ha-¹ over two years highlighted the need for better soil management, irrigation, and seed quality to achieve potential yields. Extension gaps, ranging from 124 to 151 kg ha-¹, emphasized the importance of farmer education in adopting advanced agricultural methods. The technology index declined to 17.49%, reflecting improved feasibility and adoption of the innovations over time. Economic analysis showed demonstration plots had higher net returns (` 44,406 ha-¹) and a superior benefit-cost ratio (2.85) compared to local practices (` 30,133 ha-¹; B:C ratio 2.57). Post-demonstration, significant adoption of improved practices such as field preparation, fertilizer application, and pest management was observed. This study underscores the role of CFLDs in enhancing sesame productivity, economic returns, and farmer adoption of modern agricultural practices in challenging agro-climatic conditions.

Published: February 2025

The study was conducted beginning from 2009 to 2020 (11 years) at ICAR-Indian Agricultural Research Institute, New Delhi, India to evaluate the long-term effects of various residue management practices (RMPs) on soil organic carbon (SOC) fractions in wheat based cropping systems in north-western India. A split-split plot design included four RMPs: biochar (BC) application, crop residue incorporation (CRI), crop residue burning (CRB), and complete residue removal (CRR), applied across three cropping systems: wheat-maize (WMCS), wheat–pearl millet (WPCS), and wheat–rice (WRCS). The study examined SOC mineralization, particulate organic matter carbon (POM-C), and oxidizable organic carbon (OOC) fractions. The findings reveal that BC application significantly enhances the stability of SOC, as evident from the higher activation energy (Ae) and Q10 values, particularly in macroaggregates across different soil depths. Regardless of the cropping systems, the plots treated with BC had the largest percentage of macroaggregate associated POM-C in both the soil depths, specifically 5.67 g kg-1 at 0–15 cm and 2.41 g kg-1 at 15–30 cm. Furthermore, the findings demonstrated that the application of crop residue incorporation (CRI) and BC treatments consistently increase the amount of higher labile carbon (C) available in the soil, hence promoted nutrient cycling and microbial activity. In contrast, CRB and CRR treatments showed lower SOC stability and labile C contents. These results highlight BC’s potential as a sustainable residue management strategy (RMP) for boosting soil health and SOC sequestration in wheat based cropping systems.

Pantoea dispersa strain DSM 30073 is an endophytic bacterium isolated from the Ambon banana plant. From in vitro tests, this strain shows characteristics such as PGPB (Plant Growth Promoting Bacteria) and can support the growth of Cavendish banana plants, but its effect on Ipomoea reptans is unknown. The purpose of this study was to determine the efficacy of endophytic bacteria Pantoea dispersa strain DSM 30073 against the growth of Ipomoea reptans. The research design used was a one-factor Complete Randomized Design (CRD), namely inoculation frequency (P): control (P0), one-time inoculation (P1), and two-time inoculation (P2). The inoculum was confirmed to be pure by gram staining and cultured on NB medium with a 24-hour shake at room temperature. After 24 hours, the cells were harvested, and a suspension was made by adding Ringer's solution until it reached an OD600 nm of 0.8 â€“ 1. Seeds were sterilized using 70 % alcohol followed by 1 % NaOCl for 1 minute each, then washed using sterile aquadest 3 times.Â  Sterile seeds were inoculated with an inoculum suspension for 30 minutes (P1). After inoculation, seeds are planted on a sterile soil medium. Repeated inoculation is carried out on the 11th day (P2). The growth of Ipomoea reptans is observed: plant height (cm), number of leaves (strands), leaf stretch (cm), wet weight of the plant (g), root length (cm), and number of roots (total). After 30 days, data on plant height 16.1 cm (control) â€“ 17.4 cm (inoculation), wet weight of plants 1.1 g (control) â€“ 1.4 g (inoculation 2 times), number of leaves 7 strands (control) â€“ 8 strands (inoculation 2 times), and leaf stretch 10.2 cm â€“ 10.9 cm (inoculation 2 times). Inoculation of Pantoea dispersa strain DSM 30073 had no effect on plant height growth, wet weight, leaf number, and leaf stretch but was significantly different in root parameters. It can be concluded that the Pantoea dispersa was not seen to support the growth of Ipomoea reptans significantly until 30 days after inoculation.

Authors: Hulscher Nicolas , McCullough Peter
Published: February 2025

COVID-19 vaccines have been previously associated with pulmonary hemorrhage, typically observed shortly after vaccination. We present a healthy, 47-year-old Caucasian male that died unexpectedly from acute pulmonary hemorrhage 555 days after completing the BNT162b2 (Pfizer) COVID-19 vaccination primary series. Before death, he exhibited symptoms of a mild respiratory infection. Despite a healthy medical history and no medication use, the patient’s condition rapidly deteriorated and he experienced severe respiratory distress, followed by cardiopulmonary arrest with evidence of profuse pulmonary bleeding. Autopsy findings revealed massive lung congestion without embolism, normal heart size, and moderate coronary atherosclerosis without myocardial infarction. Despite these findings, the medical examiner determined the cause of death was attributed to atherosclerotic and hypertensive cardiovascular disease, without considering the recent pulmonary hemorrhage and unremarkable medical history. The autopsy failed to investigate potential contributions from the COVID-19 vaccine, such as the presence of the Spike protein, vaccine mRNA, or related antibodies. A batch analysis revealed the BNT162b2 vaccine batch this patient received is among the top 2.8% for number of reported deaths out of all Pfizer COVID-19 vaccine batches and is associated with fatal cardiovascular adverse events including cardiac arrest. The evidence suggests that this man died of a cardiopulmonary arrest most likely as a result of acute pulmonary hemorrhage, with the COVID-19 vaccine potentially playing a role in the development of cardiopulmonary pathology and hemorrhage. We propose autopsy protocols for deceased individuals that have received one or more COVID-19 vaccines to help improve diagnostic accuracy in future cases.

Authors: Mohammed Najlaa Hosny Ameen
Published: February 2025

This research analyses the portrayal of colonialism in two literary works, namely Heart of Darkness by Joseph Conrad and Nervous Conditions by Tsitsi Dangarembga by placing them within their historical and cultural settings. Both publications explicate the power dynamics, cultural conflicts, and psychological effects linked to colonial domination.
Through the narrative of Charles Marlow’s travels in Heart of Dark- ness, Conrad reveals the brutality, exploitation, and ethical decline that frequently accompany colonial ventures. Dangarembga’s novel Nervous Conditions investigates the context of postwar Zimbabwe, through the lens of Tambudzai’s experiences. The book offers insights into the intricate relationships between gender, race, and class that arise against the backdrop of colonialism. Both works encourage readers to contemplate matters of authority, involvement, and opposition. The goal of this study is to uncover the nuanced themes and narrative strategies used by the authors to explore the topic of colonialism and thereby shed light on the intricate interplay of power, identity, and resistance within a colonial setting. It emphasizes the enduring impact of colonialism on both individuals and society, using a comparative approach to enhance our awareness of the intricacies of colonial inheritances and the significance of literature in addressing them.
