Проведен анализ влияния различных антидотов на яровую пшеницу (Triticum aestivum) сорта Тризо при стрессе, вызванном применением послевсходового гербицида Прима. Выявлено, что обработка посевов яровой пшеницы послевсходовым гербицидом в условиях Пензенской области снижала засоренность посевов, уменьшала фотосинтетическую активность и продуктивность растений. Применение антистрессантов, особенно мегафола и селената натрия, ослабляло химический стресс, вызываемый гербицидной обработкой, усиливало развитие листового аппарата, растение дольше сохраняло активную площадь ассимиляционной поверхности, что повышало фотосинтетическую деятельность яровой пшеницы и накопление сухого вещества.

An analysis of the effect of various antidotes on spring wheat (Triticum aestivum) cv. Triso under stress caused by the use of the post-emergence herbicide Prima was carried out. It was revealed that the treatment of spring wheat crops with a post-emergence herbicide in the conditions of the Penza region reduced the infestation of crops, reduced the photosynthetic activity and productivity of plants. The use of antistressants, especially megafol and sodium selenate, weakened the chemical stress caused by herbicide treatment, enhanced the development of the leaf apparatus, the plant retained the active area of the assimilation surface for a longer time, which increased the photosynthetic activity of spring wheat and the accumulation of dry matter.

В модельном эксперименте в контролируемых условиях исследовали влияние дыма, образующегося при горении растительных материалов на прорастание семян и начальный рост растений. Представлены данные по воздействию фумигации от материалов горения растительного происхождения на примере сосновых опилок на начальный рост таких сельскохозяйственных культур, как редис (Raphanus sativus), озимая пшеница (Triticum aestivum) и горох посевной (Pisum sativum). Исследовано влияние газообразных веществ на длину корней и побегов этих культур и их морфологические изменения после воздействия дыма в течение 5-30 мин. Продолжительность фумигации играет важную роль в снижении начального роста растений. Установлена высокая резистентность корней гороха к дыму. Выявлена высокая устойчивость побегов пшеницы, они обладают большей резистентностью к продуктам горения, чем редис и горох.

In a model experiment the effect of smoke generated by burning plant materials on seed germination and initial plant growth was studied under controlled conditions. Data on the e ect of fumigation from combustion materials of plant origin on the initial growth of such crops as radish (Raphanus sativus), winter wheat (Triticum aestivum) and pea (Pisum sativum) by the example of pine sawdust are presented. The e ect of gaseous substances on the length of roots and shoots of these crops and their morphological changes after exposure to smoke (5-30 min) was studied. Duration of fumigation plays an important role in reducing the initial growth of plants. High resistance of pea roots to smoke was established. High resistance of wheat shoots was revealed; they have greater resistance to the products of combustion than radish and pea

Рассмотрено структурное состояние и гранулометрический состав залежных и пахотных почв (haplic calcisols и fl uvisols calcaric) полупустыной зоны. Исследованные почвы характеризуются крайне низким содержанием гумуса. В изученных почвах преобладают гранулометрические фракции 0,05–0,005 мм. По сравнению с пашней для залежных аллювиальных луговых почв наблюдается увеличение песчаных фракций, мелкой пыли и илистых частиц, и снижение фракции крупной пыли; для залежных бурых аридных почв характерно уменьшение песчаных фракций, мелкой пыли и ила, и увеличение крупной и средней пыли. Структурное состояние пашни оценено как неудовлетворительное, а залежных почв как отличное. Установлено, что в почвах залежи по сравнению с почвой пашни значительно увеличивается содержание агрономически ценных агрегатов (для бурых аридных почв в 1,7 раза, для аллювиальных луговых в 2,1 раза), уменьшается доля агрегатов > 10 мм и < 0,25 мм. Состояние структуры целинных почв удовлетворительное.

The structural state and granulometric composition of fallow and arable soils (haplic calcisols and fl uvisols calcaric) of the semi-desert zone are considered. The studied soils are characterized by extremely low humus content. In the studied soils, granulometric fractions of 0.05–0.005 mm predominate. Compared to arable land, for long-fallow alluvial meadow soils there was the increase in sand fractions, fine dust and silt particles, and the decrease in the coarse dust fraction; fallow brown arid soils are characterized by the decrease in sand fractions, fine dust and silt, and the increase in coarse and medium dust. The structural condition of arable land is assessed as unsatisfactory, and that of fallow soils as excellent. It was established that in fallow soils, compared to arable soils, the content agronomically valuable aggregates significantly increased (for brown arid soils by 1.7 times, for alluvial meadow soils by 2.1 times), the proportion of aggregates > 10 mm and < 0.25 mm decreased. The state of the virgin soil structure was satisfactory.

In the conditions of small-scale experiment the effi ciency of fractional application of standard nitrogen fertilizers, single application of new encapsulated nitrogen fertilizers of prolonged action on the growth and decorative properties of plants for the creating new lawns were studied. A high positive eff ect based on two-year experiment was shown after the application of potassium humates together with nitrogen fertilizers in improvement of the decorative properties of new lawns (the content of chlorophyll, total nitrogen in plants, increasing of biomass, the projective covering reached maximum value). Single application of new nitrogen fertilizer of prolonged action (encapsulated urea) demonstrated the positive eff ect on the growth and development of lawn grasses, the obtained results were equivalent to fractional application of standard nitrogen fertilizers. The application of standard nitrogen fertilizers in the form of solutions reduces nitrogen losses from the soil at high temperatures and in arid conditions.

Изучили динамику популяции Hemerocallis minor как индикатора успешности реконструкции растительного покрова на отвалах вскрыши после добычи угля и проследили изменение свойств нанесенного слоя почвы для прогноза устойчивости функционирования восстановленной популяции во времени. Исследование проведено в 2018–2021 гг. на территории угледобывающего предприятия ООО «Шахтоуправление «Майское» в Кемеровской области. Установлено, что при нанесении слоя снятой почвы мощностью 20, 40, 60 см на поверхность отвала, минуя стадию буртования, популяция Hemerocallis minor восстанавливалась через 1–2 года. Отмечена тенденция к повышению рН нижних слоев нанесенного почвенно-растительного слоя (ПРС). Судя по метаболическому профилю микробного сообщества почвы, достаточно отчетливо заметно влияние тела отвала на нанесенный слой почвы. Сделан вывод, что устойчивость восстановленной популяции Hemerocallis minor во времени может быть ограничена недостатком влаги и ухудшением свойств нанесенного ПРС из-за влияния тела отвала. Действие этих факторов можно уменьшить путем увеличения мощности нанесенного ПРС.

The population dynamics of Hemerocallis minor as an indicator of the success of vegetation reconstruction on overburden dumps after coal mining was studied and the change in the properties of the applied soil layer was traced to predict the stability of the restored population over time. The study was conducted in 2018–2021 on the territory of the coal mining enterprise LLC Shakhtoupravlenie Mayskoye in the Kemerovo region (54°16'18.9 "N 86°52'48.0 "E). It was shown that when a layer of the removed soil of the thickness of 20, 40 and 60 cm was applied to the dump surface, bypassing the clamping stage, the population of Hemerocallis minor recovers in 1–2 years. The tendency to increase the pH of the lower layers of the applied top soil layer (TSL) was observed. Analysis of the metabolic profile of the soil microbial community showed the distinct influence of the dump body on the applied layer. A conclusion was made that the stability of the recovered population of Hemerocallis minor over time may be limited by the lack of moisture and deterioration of the properties of the applied TSL due to the influence of the dump body. The influence of this factor can be reduced by increasing the thickness of the applied TSL.

Design, Synthesis and Photophysical properties of an Iridium(III) complex bearing an Indolo[3,2,1-jk]carbazole-decorated NHC ligand
Authors: Griffin Máire , Mackenzie Campbell , Zysman-Colman Eli
Published: December 2024

The synthesis and characterization of a novel blue-green emitting neutral heteroleptic iridium(III) complex Ir(dFppy)2(iCzmi) (PL = 505 nm in MeCN) is reported. This represents the first example of an NHC ligand bearing an indolo-[3,2,1-jk]carbazolyl (iCz) unit, and the first use of an iCz containing ligand as the ancillary ligand in a heteroleptic Iridium(III) complex. The influence of the iCz moiety on the photophysical properties of Ir(dFppy)2(iCzmi) is explored by comparing its properties with those of the reference emitter – Ir(dFppy)2(pmi). Both complexes show similar photophysical properties, which are rationalized in terms of a detailed computational study.

Published: December 2024

The development of photocatalyst by tunning the Donor-Acceptor (D-A) properties into the covalent organic frameworks that regulate the photocatalytic production of highly valued chemical H2O2 by harvesting natural resources such as sunlight and seawater is one of the challenging tasks. In this study, we have demonstrated a systematic strategic-driven analysis to understand the role of D-A properties in an imine-linked covalent organic framework towards photocatalytic H2O2 production. We synthesized three imine-linked COF, among which triazine core containing framework COF-C demonstrated high selectivity for H2O2 generation, with a yield of 3674 μM.h-1 under an O2 saturated aqueous system in the absence of any sacrificial agents. Also, it showed a solar to chemical conversion efficiency (SCC) of 1.3% in pure water with an AQY of 36.2% in blue led (λ∼ 450 nm) in pure water. The COFs demonstrated stepwise 2e- ORR pathways leading toward photocatalytic production of H2O2, with Steller recyclability, which in the future has the potential to became a highly stable material for photocatalytic application. When benzyl alcohol was introduced to form a two-phase catalytic system, the production of H2O2 was remarkably enhanced in many folds. This work represents a series of study of COFs with significant advancement in the design that have enhanced the solar energy utilization and synthesis of value-added products.
Fewer, but better: on the benefits of surfactant-free colloidal syntheses of nanomaterials
Authors: Varga Marton , Quinson Jonathan
Published: December 2024

Colloidal syntheses are common bottom-up synthetic approaches to obtain various nanomaterials, e.g. gold nanoparticles, where a precursor, e.g. HAuCl4, is reduced in presence of reducing agents in a solvent. It is often claimed, and almost dogmatically believed, that stabilizers, capping agents, ligands, surfactants or other additives, must be added to ensure the stability of the colloids. Although there is almost a systematic use of such chemicals in the literature, a range of surfactant-free, or additive-free, colloidal syntheses have been reported. In those syntheses, the solvent plays the role of source of reducing agents and/or stabilizers. Recently, the use of alkaline solutions of low viscosity mono-alcohols, such as ethanol, has been shown to lead to stable surfactant-free colloids for various metal nanoparticles. Here, with the example of gold nanoparticles obtained at room temperature, it is shown that adding commonly reported stabilizers, such as trisodium citrate, PVP, SDS, poly(NIPAM), CTAB, or chemicals such as hydroquinone, actually does not lead to any advantages compared to the surfactant-free colloidal synthesis performed in alkaline mixture of water and 20 v.% ethanol. The results stress the potential of surfactant-free approaches compared to more conventional surfactant- and additives- assisted strategies to develop greener research studies and syntheses.
Defect Layer at the Surface of BaTaO2N and Implications for Photocatalysis
Authors: Smith Matthew , Li Wenpeng , Metha Gregory , Hisatomi Takashi , Domen Kazunari , Andersson Gunther
Published: December 2024

BaTaO2N has a valence and conduction band position which make the material a promising candidate for photocatalytic water splitting. However, the material shows a very low solar to hydrogen (STH) efficiency. It is generally assessed that the reason for the low STH is the presence of defects at the surface of the material which act as recombination centers for the excited electrons and holes. Here we show with high resolution transmission electron microscopy (HR TEM) an amorphous layer at the surface BaTaO2N which may be a cause of low STH. We demonstrate the amorphous layer can be removed through etching. Subsequently, the valence band structure is analyzed with UV photoelectron spectroscopy (UPS) and valence band X-ray photoelectron spectroscopy (VBXPS), where the latter has a significantly larger probing depth than the first. UPS reveals that non-etched BaTaO2N has a low density of states (DOS) whereas the VBXPS results are compatible with the optical band gap of the material. However, the DOS of BaTaO2N samples etched with H2SO4 solution were consistent with the optical band gap for both UPS and VBXPS measurements, indicating that after removal of the amorphous layer BaTaO2N is a suitable candidate for photocatalytic water splitting.
MTDL-GAN: De novo Design of Multi-Target Directed Ligands for Alzheimer’s Disease from Unpaired Sets of Target-Focused Chemical Library
Authors: Lee Taeyeub
Published: December 2024

BACKGROUND. Alzheimer’s disease (AD), the most common form of dementia, causes memory loss, cognitive decline, and behavioural changes, affecting over 32 million people globally. Current AD treatments that focus on single-target intervention often fail to significantly slow disease progression and may not be effective for all patients. Given AD's complex nature, a more effective approach may involve targeting multiple pathways simultaneously. METHODS. This study proposes the use of a cycle-consistent adversarial network to design multi-target directed ligands (MTDL-GAN), drugs designed to inhibit two primary AD target enzymes simultaneously. Our targets of interest are acetylcholinesterase (AChE), beta-secretase 1 (BACE1), and glycogen synthase kinase 3 beta (GSK3), which are known to have significant impacts on the progression and development of AD, each with a different mechanism of action. Inhibitor libraries were curated from ChEMBL27 and further characterized to represent each inhibitor domain, resulting in 69 AChE, 572 BACE1, and 246 GSK3 inhibitors. The MTDL-GAN was trained on these unpaired datasets to generate MTDL-like molecules. During the model training, all generated molecular structures were stored to create in silico MTDL libraries. From each MTDL library, 300 molecules were sampled for further analysis. Tanimoto similarity scores were computed to assess the structural similarity of the generated molecules to the target inhibitor domain, and molecular docking simulations were carried out to validate their \textit{in silico} binding affinities to the target enzymes. RESULTS. The proposed method effectively transformed molecules from the original inhibitor domains into MTDL-like molecules while maintaining their structural similarity to the original inhibitors. Less than 0.15% of the generated molecules have a Tanimoto similarity score above 0.85 to the known bioactive molecules in ChEMBL27, highlighting their structural novelty and potential for exploring new chemical space. Further investigation revealed that the sampled MTDLs demonstrate promising in silico dual-binding affinity while having favourable physicochemical properties and synthetic tractability. Among these, several MTDLs surpassed the in silico binding affinities of investigational drugs in phase 2/3 clinical trials. Molecular structures of these hit MTDLs are publicly available for academic research.

Published: December 2024

The focus of this research examines the symbols in various decorative shield motifs of the Taman Dayak tribe. The topic of study is related to the concept of decorative shield motifs in the Taman Dayak tribe. The shield of the Taman Dayak tribe is called Jabang or Kelau. Jabang (adjective) means a shield or protector who guards or protects. Kelau (noun) means shield as an object. As an object to decorate household furniture. For the Dayak Taman tribe, shields were used as body protection against spears, sabers or chopsticks during past wars. Seeing its function as a protective band, the shield must be made of strong material, not easily broken, broken, destroyed and light enough so that it is easy to use. The researcher used descriptive qualitative methods and critical reading of the text, namely: (1) Cultural philosophy books related to understanding the concept of symbolic motifs of the decorative shield motifs of the Taman Dayak tribe; (2) Articles that concentrate on studying the concept of motif symbols. The findings in this research are that the concept of symbols in the decorative motifs on the shields of the Dayak Taman tribe is a decoration that is believed to bring good luck to the wearer. The webbing is used to strengthen the shield as well as for its beauty. Nowadays, shields have changed their function from protective equipment to decoration, from weapons of war to traditional dance instruments. However, it is good to preserve the existing decorations, because they contain messages of wisdom about the harmony of life in the universe.

Obesity is a condition where there is an accumulation of excess body fat, which can
increase oxidative stress either in the blood or in tissues, such as brain tissue. This
situation can trigger atrophy in neurons and reduce brain-derived neurotrophic factor
(BDNF) levels, which can increase the risk of impaired cognitive function. This study
aimed to ascertain the effect of oyster mushroom (Pleurotus ostreatus) β-glucan extract on
the number of neurons and levels of BDNF in rats. The study design was a true

approach. Although there was no significant difference in the number of neurons (p =
0.692), the data revealed a significant difference in BDNF levels (p = 0.005). There was
no relationship between the number of neurons and BDNF levels (p = 0.874) and between
the β-glucan dose and the number of neurons (p = 0.796). However, there was a
relationship between β-glucan dose and BDNF levels (p = 0.001; r = 0.695). This study
concludes that the dose of β-glucan from oyster mushroom extract positively affects
BDNF levels but not the number of neurons. There was no relationship between the
number of neurons with BDNF levels and β-glucan dose. It was presumable because the
staining technique was less specific, so the possibility of other cells counted as neurons
may occur

A Method for Determining the Importance of Critical Emergency Indicators Based on Multi-granularity Uncertain Language
Authors: Yi Yongguang , Wang Zengqiang
Published: December 2024

In view of the complexity of emergencies and the subjectivity of decision-makers, a method of determining key emergency indicators based on multi-granularity uncertainty language is proposed. Firstly, decision members use preferred uncertain language phrases to represent the importance of each key indicator and use transformation functions to carry out the consistent transformation of this multi-granularity uncertain language information. Secondly, the group evaluation vector is obtained by using the extended weighted average operator of uncertainty, and then the weight vector of each key index is obtained by using the decision theory of uncertain language. Finally, an example is given to verify the practicability and effectiveness of the proposed method.

Published: December 2024

Stylosanthes is an excellent tropical leguminous forage. Anthracnose caused by Colletotrichum gloeosporioides is a major limiting factor in Stylosanthes production, which can lead to reduced forage and seed production and decreased quality. How to quickly screen resistant parents and varieties of Stylosanthes that are resistant to anthracnose has become an urgent problem to be solved in production. In this study, the high-performance liquid chromatography detection technology was established for simultaneous analysis of the content of salicylic acid, triethyl orthobenzoate, indazole, and soyasapogenol B in Stylosanthes leaves. The technology was further applied in the analysis of the relationship between secondary metabolites and resistance to anthracnose in 105 accessions of Stylosanthes. The result shows that salicylic acid is the most important factor for resistance to anthracnose. By detecting the content of salicylic acid in Stylosanthes leaves, a rapid screening technology for anthracnose-resistant parents and varieties of Stylosanthes was established, and 5 accessions of Stylosanthes with high resistance to anthracnose were screened. This study is of great significance to the Stylosanthes germplasm preservation and identification and its breeding.

Analyzing the Deconstruction and Reinvention of Infernal Affairs and The Departed Remake from a Cross-Cultural Perspective
Authors: Cao Luyin
Published: December 2024

The purpose of this article is to comprehensively analyze the phenomenon of deconstruction and reinvention in the remake process of the film Infernal Affairs (2002) and its Hollywood remake The Departed (2006) from a cross-cultural perspective. With the continuous advancement of globalization, the film is an important carrier of cultural communication, so its cross-cultural remake has become an important bridge connecting different cultures. Hollywood, as the leader of the global film industry, has not only maintained the vitality of the industry through the remake strategy but also successfully absorbed the cultural creativity of Asian countries. Taking The Departed and Infernal Affairs as examples, this paper explores in detail the differences in cultural positioning, the shift in narrative purpose, the similarities and differences in characterization, as well as the use of visual styles and the aesthetics of violence in the remakes of the two films. The study finds that Hollywood has profoundly deconstructed the Chinese cultural elements in the original film during the remake process, and reconstructed a narrative system in line with the American cultural background, thus realizing cultural reconstruction and dissemination. This process not only reflects the influence of cultural differences on film creation but also reveals the complexity of cultural infiltration in the context of globalization.
