Allyship

Published: December 2024

When is an Ally not an Ally to Indigenous, marginalized, or racialized peoples? How important is it that today's youth are stepping up to fight the good fight for others?  Many questions arise when mentioning allyship and how it works.  What is the benefit?  Is there a benefit?  All good questions, and in this article, I intend to address the real issues involving the support of others towards these racialized and marginalized peoples.  It is noted that not all “famous” people, or celebrities that support our causes have the best intentions, and they may take away from those on the ground floor doing the work.  It is tireless, unappreciated work that goes unrecognized almost all the time, with the primary individuals or groups being placed in the spotlight…or even the limelight.  This is about supporting those people as human beings without asking for acknowledgment or accolades and feeling fulfilled by their actions only.  Exposing those such as Lorde, the artist from New Zealand, or educators from across this country whom we call pretendians builds an alliance with those who want social justice and believe that we all fight the good fight.

The research was conducted in 2018, 2020, and 2022 on the central experimental base of V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasno-dar. The purpose of the research was to state regularities of manifestation of main economically valuable traits of the highly oil variety Master during selection of promising families due to the results of their studying in a nursery of progeny estimation. As the initial material we used progenies of individual plants from elite population of the variety Master selected by seed weight from a head, oil content. During a vegeta-tive period, phenological observations and biometric measures due to the common technique were conducted. Oil content in seeds was determined by a method of nuclear magnetic resonance on a NMR-analyzer AVM-1006M due to the State Standard 8.597-2010. As indicators of variability, we used middle, minimal, and maximal meanings of a trait, a range of variability was determined. The changes in the structure population under influence of the selec-tion process were established by distributing the individual families into groups of trait expression. The intensity of rouge-off was determined by the ratio of the number of rouged-off families to the total num-ber in the initial population. It was found that over the years of research, the average yield in the proge-nies of selected plants was 3.17 t/ha, in the control – 3.02 t/ha; in oil content, respectively, 53.1 and 52.8%. Assessment and selection of the individual plants in the population contributed to the accumulation of highly productive biotypes, which led to an increase in yield by 5 %, compared to the control. The height of the plants and the oil content of the seeds remained almost at the same level as for this variety.

The main purpose of the work was to improve elements of the protection system of sunflower seeds and plants against diseases. A system of protective measures was tested, including tank mixtures of fungicides of biological and chemical origin and agro-chemicals against a complex of the most common harmful diseases on large-seeded sunflower variety Karavan bred at VNIIMK. The choice of fungicides for pre-sowing seed treatment and sunflower vegetation treatment was based on previously obtained data, which showed the best result in the laboratory conditions. The research was conducted at the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) in 2022 and 2023. The determination of biological efficiency and yield was carried out according to the generally accepted methods of VNIIMK and VISR. The main diseases on sunflower during the years of the research were downy mildew, alternariosis, bacteriosis and phomopsis. The com-bined use of an insecto-fungicidal tank mixture Scarlet, OE (imazalil, 100 g/l + tebuconazole, 60 g/l), 0.4 l/t + Apron XL, WE (mefenoxam, 350 g/l), 3.0 l/t + Potassium humate, 2.0 l/t + Kruiser, EC (thiamethox-am, 350 g/l), 8.0 l/t, followed by double treatment according with Mystery, OE (diphenoconazole, 40 g/l + pyraclostrobin, 80 g/l + tebuconazole, 80 g/l), 1.0 l/ha during the vegetative period allowed not only to reduce the prevalence of the main pathogens in the crop, but also to obtain the largest amount of saved yield – 0.60 t/ha.

Heterosis is a manifestation of increased hybrid vigor, usually observed in the first generation. In sunflower hybrids, as well as in many other cross-pollinated agricultural crops, heterosis is achieved by crossing maternal cytoplasmic male-sterile lines with pollen fertility restorers. Numerous data on the study of heterosis phenomena in this crop are given. Interrelations of economically useful traits in parental lines and their hybrids are shown. Genome sequencing is one of the most promising methods of developing highly productive sunflower hybrids.

There is presented an analysis of literary sources on the following issues: the concept of rhizosphere and its boundaries; composition and role of root exudates, fungi and bacteria; peculiarities of biological activity of soil; specificity of its some chemical and physical properties in rhizosphere. It is shown that the rhizosphere soil significantly differs from the bulk soil by the majority of parameters characterizing both the composition of solid phase and solution and functioning of separate components of the soil system. Rhizosphere soil contains a large number and diversity of microorganisms. The presence of these various substances and microorganisms leads to significant changes in the cycles of chemical reactions, to intensification of carbon cycle, nitrogen and phosphorus assimilation and organic matter decomposition. In the rhizosphere of sunflower with the increase in the number of microflora, the yield of plants increased. Hybrids have the most effective and stable structure of microflora in the rhizosphere of sunflower, the least – lines have the least one, which is determined by genetic features of agropopulation and excretion of root exometabiotics, which determine the development and activity of trophic groups of microorganisms.

Introduction. Modern fire protection systems use various technologies to detect the source of a fire and transmit a fire signal. They may also include systems for monitoring fire parameters. With the help of such systems, the rate of fire development can be predicted based on information received from the system based on monitoring results. This information may include temperature, smoke, oxygen levels and other parameters that can be measured in the combustion area. Fire protection systems can use this information to determine how quickly a fire is spreading and determine the most effective fire suppression methods. This may include changing the settings of the fire extinguishing or smoke removal system, as well as calling the fire services. Goals and objectives. Studying the specifics of changes in fire parameters based on the software implementation of a probabilistic model for predicting the rate of fire development and probability estimates of adverse events occurring at the protected site. Methods. The study used methods of mathematical modeling and forecasting, methods of set-theoretic description of complex processes; theory of relative importance of criteria. Results and discussion. A probabilistic model for predicting the rate of fire development has been developed to assess the probability of adverse events occurring at a fire protection facility. A software implementation of a probabilistic model using a software tool for computer modeling of fire dynamics monitoring is presented. Conclusion. A probabilistic model for predicting the rate of fire development can be useful in determining the actual rate of fire development and assessing the probability of the occurrence of various adverse events at the protection site during a fire. If this model is implemented in software, it can be used to automate the decision-making process, as well as to analyze large amounts of data and predict possible risks. In addition, such a model can be used to coordinate the actions of various fire departments, which will allow more efficient use of resources and reduce risks during a fire.

Introduction. Currently, due to the suspension of control and supervisory activities, state fire supervision units are carrying out a lot of work on fire prevention in order to reduce the number of fires through preventive measures. Existing regional information databases for recording fires make it possible to obtain the necessary information about these fires: from the time of reporting to the quantitative characteristics and damage caused. This information allows you to solve a number of problems and use statistical data on fires and their consequences with further development towards the use of artificial intelligence methods to predict the effectiveness of ongoing preventive measures. The result of such work may be testing the hypothesis about the impact of preventive measures on the cleanliness of fires in a particular municipality. Goal and task. The purpose of the study is to provide information support for management by managers of the organizational system of state fire supervision, compliance with preventive measures in an operational situation with fires, depending on the size of the settlement. To achieve the goal, it is necessary to perform cluster analysis of the data, create a prototype of a classifying neural network and construct a histogram for testing the null hypothesis of the Shapiro-Wilk test. Methods. Cluster analysis and intelligent analysis of data on fires in the selected territory were adopted as a scientific basis. Results and discussion. The expected result is information support for the heads of state fire supervision, which will improve the process of planning the work of the engineering and inspection staff of departments and improve the quality of preventive work. Conclusions. Based on the results of computational experiments, it was possible to come to the conclusion that the effectiveness of preventive measures depends on the size of the municipality and the size of the living population. It is proposed that heads of local fire supervision units, when planning the activities of employees, take into account the current operational situation with fires and pay attention to the content and quality of preventive measures, especially in mixed and rural municipalities (type 2 and type 3). The use of modern methods of data mining makes it possible to provide information support to the heads of state fire supervision when organizing preventive measures for the selected municipality.

Introduction. Within the framework of this article, the need to solve a thermal
engineering problem aimed at ensuring the fire safety of tanks with a protective wall is
substantiated. Computational modeling was also carried out using the developed
mathematical model to determine non-stationary temperature fields and stress-strain
states that arise in the bodies of a model tank with a protective wall under fire
conditions, with a nominal capacity of 700 and 5000 m3. Purpose and objectives.
Experimental and theoretical assessment of the non-stationary temperature field of the
protective wall of a "glass in a glass" type tank with oil and petroleum
products to predict its stability in case of fire. The task is to develop and test a
mathematical model in order to carry out numerical simulation of the interaction of a
fire flame with the protective wall of a tank to determine its non-stationary
temperature fields. Research methods. Numerical modeling was carried out on the basis of
a modern computing platform – COMSOL Multiphysics, which allows you to conveniently and
accurately simulate complex and complex physical processes, including the interaction of
an oil fire flame with the tank body and its protective wall. Results and its
discussion. As a result of numerical modeling, the values of the distribution of thermal
fields and the stress-strain state on the main tank and the protective wall of the
"glass in a glass" type tank were obtained. The calculation results are
visualized in the form of isofields, which also allows you to clearly understand the
distribution of temperature fields and stresses on each belt of the tank. Conclusions:
The results of numerical modeling were obtained to determine the non-stationary
temperature fields and stress-strain state that arise in the body of a mathematical
model of a tank with a protective wall under fire conditions. The developed and
justified numerical modeling method was tested on a reservoir with the most common
nominal capacity in operational practice, 5000 m3, with its corresponding geometric
parameters. The results of a complex numerical calculation showed that the temperature
value of the protective wall body in its upper zone can significantly exceed its
critical heating temperature and amount to about 720 °C, at which a stress-strain state
occurs. Keywords: reservoir; protective wall; oil; mathematical modeling; mathematical

Published: December 2024

Objectives:

Symptoms of anxiety and depression are more common in adolescents with type 1 diabetes (T1D) than in their peers without diabetes, and annual screening for psychological comorbidities is recommended in these patients. We aimed to pilot a screening protocol for symptoms of depression and anxiety in an adolescent T1D clinic to (i) establish the baseline prevalence of anxiety and depression symptoms and (ii) determine the feasibility and acceptability of the screening process.

Material and Methods:

Adolescents with T1D aged 14–18 years who were not currently accessing psychological services were screened using the patient health questionnaire-9 and generalized anxiety disorder-7 assessment. Patients reporting mild-severe symptoms of anxiety and/or depression were referred for further assessment and referral to psychological services, if appropriate.

Results:

20% of patients were already engaged with mental health services and so were not screened. Of the remaining patients, 29% reported experiencing mild-severe depressive symptoms, and 18% reported experiencing mild-severe anxious symptoms. Furthermore, the use of these screening tools identified one patient in need of urgent intervention, who was taken to the hospital emergency department.

Conclusion:

Our results highlight the importance of regular mental health screening using validated tools to capture all the patients who may benefit from referral to psychological services.

С использованием метода проростков проведена оценка эффективности наночастиц серебра, стабилизированных различными поверхностно-активными веществами, в качестве агентов для нанопраймирования. Показано, что при концентрации 50 мг/л наночастицы не влияли на энергию прорастания семян пшеницы мягкой Triticum aestivum L. при продолжительности нанопраймирования 6 и 15 ч, но снижали этот показатель на 6-18 процентных пунктов при обработке в течение 24 ч. Нанопраймирование всеми исследованными наночастицами серебра приводило к увеличению длины корней и побегов проростков и индекса жизнеспособности семян. Оптимальное время праймирования составило 15 ч вне зависимости от типа стабилизирующего агента наночастиц серебра. Максимальный эффект был обнаружен для наночастиц серебра, стабилизированных карбоксиметилцеллюлозой и олеатом натрия, характеризующихся наибольшими размерами и наименьшими абсолютными значениями электрокинетического потенциала.

The performance of silver nanoparticles stabilized by various surfactants as agents for nanopriming was evaluated using the seedling method. The nanoparticles at the concentration of 50 mg/l was shown to do not affect the germination energy of common wheat (Triticum aestivum L.) seeds if nanopriming continued 6 and 15 hours, but this indicator reduced by 6-18 percentage points when processed for 24 hours. Nanopriming with all the silver nanoparticles studied led to an increase in the length of the roots and shoots of seedlings and the vigor index of seeds. The optimal priming time was 15 hours, regardless of the type of stabilizing agent of silver nanoparticles. The maximum effect was found for silver nanoparticles stabilized with carboxymethyl cellulose and sodium oleate, characterized by the largest size and absolute value of the electrokinetic potential.
АГРОХИМИЧЕСКИЕ И БИОХИМИЧЕСКИЕ ПАРАМЕТРЫ ПЛОДОРОДИЯ ПАХОТНОЙ И ЦЕЛИННОЙ ДЕРНОВО-ПОДЗОЛИСТОЙ ПОЧВЫ ПРЕДУРАЛЬЯ

Изучено влияние минерального удобрения (NPK) на агрохимические свойства дерново подзолистой почвы и урожайность культур в длительном стационарном опыте в пятой ротации полевого севооборота. Практически по всем культурам наблюдалось повышение урожайности при внесении в почву NPK. Однако, повышение дозы минеральных удобрений выше 60 кг д.в./га не привело к существенному росту урожайности возделываемых культур. Проведено сравнение основных показателей плодородия и ферментативной активности пахотных и целинных дерново-подзолистых почв. Исследуемая почва изучаемых вариантов опыта имела «очень бедную» и «бедную» степень обогащенности каталазой и дегидрогеназой, которая находилась в корреляционной зависимости от кислотности почвенного раствора, r = 0,75 и 0,40 соответственно. Обогащенность почвы ферментами группы гидролаз находилась на уровне «бедной» и «средней» по шкале Звягинцева. В условиях вегетационного периода 2017 г. не установлено связи уреазной активности с содержанием в почве углерода и общего азота. В целинной почве уровень ферментативной активности гидролитических ферментов в 2-3 раза выше, чем в пахотной почве, получающей минеральные удобрения.

The influence of mineral fertilizer (NPK) on the agrochemical properties of soddy-podzolic soil and crop yield in a long-term stationary experiment in the fifth rotation of the field crop rotation was studied. In almost all crops, an increase in yield was observed when NPK was introduced into the soil. However, an increase in the dose of mineral fertilizers above 60 kg primary nutrient / ha did not lead to a significant increase in the yield of cultivated crops. The comparison of arable and virgin soddy-podzolic soils by the content of the main parameters of fertility and by enzymatic activity is carried out. The studied soil of the studied variants of the experiment had a "very poor" and "poor" degree of enrichment with catalase and dehydrogenase, which was correlated with the acidity of the soil solution, r = 0.75 and 0.40, respectively. The soil enrichment with hydrolase group enzymes was at the level of "poor" and "average" on the Zvyagintsev scale. The weather conditions of the growing season in 2017 did not allow us to establish a connection between urease activity and the content of carbon and total nitrogen in the soil. In virgin soil, the level of enzymatic activity of hydrolytic enzymes is 2-3 times higher than in arable soil receiving mineral fertilizers.
Фосфорное удобрение усиливает действие азота на урожай и качество пшеницы

Published: December 2024

В исследованиях Курганского НИИСХ - филиала ФГБНУ УрФАНИЦ УроРАН было сравнено влияние на урожайность и качество зерна яровой пшеницы действия и последействия фосфорных удобрений при разных уровнях внесения азотного удобрения в вариантах: 1) без фосфорного удобрения, 2) на фоне последействия многолетнего применения суперфосфата (Р21) 3) на фоне Р21 с последующим 10-летним внесением аммофоса (Р26). Возобновление применения фосфорного удобрения содействовало увеличению накопления клейковинных белков в зерне пшеницы на 1-2 процентных пункта (п. п.) в среднем за 2008-2017 гг., а в 2011 и 2012 гг. - на 6-7 п. п. к применению одного азота. Увеличение сбора клейковины, обусловленное как прибавкой урожая, так и повышением содержания клейковины в зерне, на фоне Р26 было существенно выше по отношению к фону Р21. Положительное действие фосфора заметнее проявлялось при недостатке влаги, когда растения активнее используют фосфор из гранул удобрения, чем из запасов высохшей почвы.

In the studies conducted in the Kurgan research Institute of agriculture - branch of FSBSI UrFASRC, UrB RAS the effect and aftereffect of phosphorus fertilizers on the yield and grain quality of spring wheat at different levels of nitrogen fertilizer are compared in the variants: 1) without phosphorus fertilizer, 2) on the background of the aftereffect of long-term application of superphosphate (P21), 3) on the background of P21 with subsequent 10-year additional fertilization with ammophos (Р26). The resumption of the use of phosphorus fertilizer contributed to an increase in the accumulation of gluten proteins in the wheat grain by 1-2 percentage points (p. p.) on average for 2008-2017, and in 2011 and 2012 by 6-7 p. p. versus the separate use of nitrogen. The increase in gluten harvest, due to both the increase in yield and the increase in gluten content in grain, against the background of P26 was significantly higher compared to the background of P21. The positive effect of phosphorus was more noticeable when there was a lack of moisture, when the plants make more use of phosphorus from fertilizer granules than from stocks of dried soil.

В статье представлены результаты исследований, которые проводились на опытном поле Нижегородского НИИСХ по изучению влияния различных паров на агрофизические свойства светло-серой лесной почвы, такие как плотность и структурно-агрегатный состав. Наблюдение за плотностью почвы осуществлялось в три срока: по всходам озимой пшеницы, в начале весенней вегетации и после уборки культуры. Установлено, что наибольшим разуплотняющим действием обладали сидеральные пары из лядвенца рогатого (Lotus corniculatus L.) и клевера лугового (Trifolium pratense L.). Разрыхляющее воздействие многолетних трав положительно повлияло на формирование агрономически ценных фракций в почве (0,25-10 мм). Количество почвенных агрегатов этой фракции в варианте, где предшественником озимой пшеницы являлся лядвенец рогатый на сидерат с использованием азотно-фосфорно-калийных удобрений составлял 75 %, коэффициент структурности - 3,0. Высокий показатель структурности отмечался при запашке под озимую пшеницу сидеральной массы клевера лугового - 2,5 (по фону Р90К90) и 2,6 (по N60Р90К90).

The article presents the results of research, conducted on the experimental field of Nizhny Novgorod Research Agricultural Institute, to study the effect of different fallows on the agrophysical properties of light-grey forest soil, such as density and structural and aggregate composition. The monitoring of soil density was carried out in three periods: on winter wheat seedlings; at the beginning of spring vegetation and after harvesting crop. The most decompression effect of green manure had the fallows occupied by Lotus corniculatus L. and Trifolium pratense L. The loosening effect of perennial grasses had the positive effect on formation of agronomically valuable fractions in the soil (0.25-10 mm). The number of soil aggregates of this fraction in the variant where the predecessor of winter wheat was Lotus corniculatus L., used as green manure with application of nitrogen-phosphorus-potassium fertilizers, was 75%, the structural coefficient - 3.0. The high rate of structural properties was observed after ploughing green manure mass of Trifolium pratense L. - 2.5 (background Р90К90) and 2.6 (background N60 Р90 К90).

On the connection between the Exact Factorization and the Born-Huang representation of the molecular wavefunction
Authors: Schürger Peter , Lassmann Yorick , Agostini Federica , Curchod Basile
Published: December 2024

In these Notes we present a new perspective on the exact-factorization expression of a molecular wavefunction, which does not rely of the probabilistic interpretation of the molecular wavefunction as a joint probability amplitude. Instead, we demonstrate a close relation with the traditional Born-Huang representation, as the exact factorization emerges as the representation in the basis the of eigenvectors of the electronic density matrix. In doing so, the partial normalization condition and gauge freedom arise naturally from the formalism. In a second part, we derive the equation of motion in the here introduced exact factorization basis.

Published: December 2024

Aqueous solubility is one key property of a chemical compound that determines its possible use in different applications from drug development to materials sciences. In this work, we present an aqueous solubility prediction study that leverages a curated dataset merged from four distinct sources. This unified dataset encompasses a diverse range of organic compounds, providing a robust foundation for our investigation of solubility prediction. Our approach involves employing a variety of machine learning and deep learning models that combine an extensive array of chemical descriptors, fingerprints, and functional groups. This methodology is designed to address the complexities of solubility prediction, and it is tailored to achieve high accuracy and generalization. We tested the finalized model on a diverse dataset of 1282 unique organic compounds from the Husskonnen dataset. The results of our analysis demonstrate the success of our model, which, given an R2 value of 0.92 and an MAE value of 0.40, outperforms existing prediction methods for aqueous solubility on one of the most diverse datasets in the field.

Published: December 2024

There is an ambiguity whether guava (Psidium guajava) leaves support or inhibits coagulation as it was commonly used as wound dressing. Our previous study extracted, identified, and screened using docking, bioactive compounds from guava leaves that has the potential to be coagulation factor IXa inhibitor. Docking has static limitations that require further evaluation [1]. To investigate the potential of bioactive compounds as inhibitors of coagulation factor IXa (CFIXa) using molecular dynamics (MD) simulations and binding free energy perturbation analyses.Top three docking-scored CFIXa-ligand complexes from our previous study were evaluated using MD simulations with GROMACS 2024 and CHARMM force fields. Simulations included minimization, NVT, NPT with and without restraints, followed by a 10 ns production run. Structural analysis was performed using RMSD, RMSF, SASA, and secondary structure analysis in UCSF ChimeraX. Binding free energies (ΔGbind) were calculated using gmx_mmpbsa with PB and GB models, and decomposition analysis identified key residues contributing to binding. Compound 7 showed the strongest binding with CFIXa, with a binding free energy ranging from -10 to -20 kcal/mol and stable interactions, particularly at H:THR245, while compound 2 demonstrated moderate binding with a binding free energy of -5 to -15 kcal/mol. Compound 3 exhibited instability, with RMSD fluctuations from 0.06 to 7.71 nm, and binding free energy approaching 0 kcal/mol, confirming its unbinding during the simulation. Compound 7 demonstrated the strongest binding interactions and stability, making it the most promising candidate for further development, while compound 2 showed moderate binding and potential for optimization through structural refinements. In contrast, compound 3 exhibited instability and weak binding, suggesting that modifications could improve its binding efficiency and specificity.
