Published: November 2024

Penelitian ini bertujuan untuk mengetahui konsentrasi Total Suspended Solid (TSS) dan pola sebaran sedimen tersuspensi di muara Sungai Peniti, Kabupaten Mempawah, Kalimantan Barat. Titik sampling ditentukan berdasarkan metode purposive sampling. Terdapat 6 stasiun pengambilan sampel yaitu Stasiun 1-3 mewakili daerah muara sungai dan Stasiun 4-6 mewakili daerah arah lepas pantai, 500 meter dari mulut muara. Data yang dikumpulkan di masing-masing stasiun adalah data kedalaman, TSS, dan TDS. Nilai kedalaman diperoleh menggunakan depth finder, dan sampel air untuk TSS yang diambil menggunakan water sampler kemudian dianalisis menggunakan metode gravimetri, dan data TDS diukur menggunakan TDSmeter. Pola sebaran TSS diperoleh berdasarkan analisis data citra Landsat 8 dari tahun 2018-2020 yang didapatkan dari USGS. Hasil penelitian menunjukkan bahwa bagian lepas pantai lebih dangkal (1,1 m) dibandingkan dengan kedalaman di mulut sungai (1,5 m). Konsentrasi TSS tertinggi pada Stasiun 2, bagian mulut muara, dengan nilai 33203 mg/l dan terendah di Stasiun 4, lepas pantai, dengan nilai 45 mg/l. Tingginya konsentrasi TSS dapat mengakibatkan tingginya tingkat kekeruhan. Hasil pengukuran lapangan menunjukkan bahwa pola sebaran sedimen di muara sungai cenderung ke arah utara. Berdasarkan citra Landsat 8 diketahui bahwa pola sebaran TSS pada setiap musim, sedimen menyebar ke selatan pada Musim Barat dan sebaliknya akan menyebar ke utara pada Musim Timur. Pada Musim Peralihan I dan II, sedimen akan menyebar ke dua arah yang berbeda (utara dan selatan).

The power of Hellmann-Feynman theorem: Kohn-Sham DFT energy derivatives with respect to the parameters of exchange-correlation functional at linear cost
Authors: Kadilenko Evgeny M. , Grinis Roland
Published: November 2024

Efficient methods for computing derivatives with respect to the parameters of scientific models are crucial for applications in machine learning. These methods are important when training is done using gradient-based optimization algorithms or when the model is integrated with deep learning, as they help speed up calculations during the backpropagation pass. In the present work, we applied the Hellmann-Feynman theorem to calculate the derivatives of the Kohn-Sham DFT energies with respect to the parameters of the exchange-correlation functional. This approach was implemented in a prototype program on the basis of Python package PySCF. Using the LDA and GGA functionals as examples, we have shown that this approach scales approximately linear with the system size for a series of n-alkanes (CnH2n+2, n=4...64) with a double-zeta basis set. We demonstrated a significant speedup in the derivative calculations in comparison with the widely used automatic differentiation approach such as pytorch based DQC, which has a computational complexity of O(n^2.0) - O(n^2.5).

Published: November 2024

Redox flow batteries (RFBs) have emerged as significant energy storage systems amid the growing adoption of renewable energy. However, the advancement of all-organic RFBs is hindered by material crossover, limited energy density, and the time-consuming selection of suitable electrolyte partners. To address these challenges, bipolar redox-active organic molecules (BRMs) show promise for charge storage in symmetric organic redox flow batteries (SORFBs), although their development can be complex and tedious. In this study, we report an approach aimed at streamlining the identification of suitable compounds through an examination of the organophotocatalyst literature, illustrated through six acridinium compounds exhibiting stable redox states. These compounds were thoroughly characterized in electrochemical cells and subjected to cycling tests in fully symmetric flow batteries. Notably, a trisubstituted electron-rich acridinium compound emerged as a potential candidate, demonstrating over 20 days of cycling stability. Given the extensive library of organic catalysts and the advantages of SORFB designs, this approach will prove to be essential for developing an innovative electrochemical storage system.

Dissolution Dynamic Nuclear Polarization (dDNP) is a powerful hyperpolarization technique enabling sensitivity gains beyond four orders of magnitude in solution nuclear magnetic resonance (NMR). Over the last decades, researchers’ efforts have led to an extension of dDNP applications in fields such as imaging, metabolomics, and drug discovery. Lithium-ion batteries are one of the most widespread types of rechargeable batteries, which calls for a deeper understanding of the various physicochemical mechanisms involved in making them more efficient, safe, and sustainable. One of the key challenges lies in better understanding and limiting the degradation of the battery electrolyte, which can significantly impact the battery’s performance. While NMR has been used in attempts to understand these mechanisms, notably by investigating the degradation products, the intrinsic lack of sensitivity of this technique, combined with the limited accessible volume of such compounds, makes its application often challenging. In this work, we combine several state-of-the-art dDNP methodologies to acquire with high sensitivity solution 13C NMR spectra of battery electrolytes. We show that we can successfully detect hyperpolarized 13C signals on formulated battery electrolyte solutions on a 600 MHz spectrometer with sensitivity gains of up to 3 orders of magnitude. This work paves the way for studying lithium-ion battery electrolyte degradation under real usage conditions (cycling, thermal aging, air exposure…) with a 13C detection limit below the micromolar range. This methodology has the potential to provide new insights into degradation mechanisms and the role and effectiveness of additives to mitigate electrolyte degradation.
Triethoxysilane-Catalyzed Single and Sequential Regioselective Hydroboration of Terminal Alkynes: Sustainable Access to E-Alkenylboronate and Alkyl Gem-Diboronate Esters by Non-Covalent Interactions
Authors: Kaur Harleen , Ahuja Himani , Arevalo Rebeca
Published: November 2024

Triethoxysilane was found an efficient catalyst for the synthesis of E-alkenyl- and alkyldi-boronate esters by the single and sequential hydroboration of terminal alkynes respectively with pinacolborane. Mechanistic studies support that the formation of diboronate esters proceeds by a double hydroboration pathway with the steric and electronic profile at Si being key to enable the second hydroboration step. Weak non-covalent interactions involving the Si and the C≡C or C=C bonds in the alkynes or alkenylboronate esters have been identified as responsible for substrate activation toward the addition of HBPin, and the reaction of HSi(OEt)3 with HBPin as a catalyst deactivation pathway.
Protein-driven electron transfer process in a fatty acid photodecarboxylase

Published: November 2024

Naturally occurring photoenzymes are rare in nature, but among them, fatty acid photodecarboxylases derived from Chlorella variabilis (CvFAPs) have emerged as promising photobiocatalysts capable of performing redox-neutral, light-induced decarboxylation of free fatty acids (FAs) into C1-shortened n-alka(e)nes. Using a hybrid QM/MM approach combined with a polarizable embedding scheme, we identify the structural changes of the active site and determine the energetic landscape of the forward electron transfer (fET) from the FA substrate to the excited flavin adenine dinucleotide. We obtain a charge-transfer diradical structure where a water molecule rearranges spontaneously to form an H-bond interaction with the excited flavin, while the FA’s carboxylate group twists and migrates away from it. Together, these structural modifications provide the driving force necessary for the fET to proceed in a downhill direction. Moreover, by examining the R451K mutant where the FA substrate is farther from the flavin core, we show that the marked reduction of the electronic coupling is counterbalanced by an increased driving force, resulting in a fET lifetime similar to the WT, thereby suggesting a resilience of the process to this mutation. Finally, through QM/MM molecular dynamic simulations we reveal that, following fET, the decarboxylation of the FA radical occurs within tens of ps, overcoming an energy barrier of ~0.1 eV. Overall, by providing an atomistic characterization of the photoactivation of CvFAP, this work can be used for future protein engineering.
New method for extraction, identification and quantification of Non-Intentionally Added Substances (NIAS) in polystyrene

Published: November 2024

An efficient one-step extraction method was developed for the recovery of additives and Non-Intentionally Added Substances (NIAS) from polystyrene, performed at room temperature for 2.33 hours, without grinding to avoid fostering the formation of NIAS unrelated to polymer processing. Solvent use (39.2 mL/g) was greatly reduced compared to extraction conditions previously reported. The study of NIAS is analytically challenging but with high importance since their presence is a potential threat to human health and to the environment while reducing plastic potential recyclability. For an understanding of NIAS formation and influence of processing parameters, a systematic approach was taken, using virgin polystyrene mixed with known quantities of standard additives as model materials (Irganox_1076, Tinuvin_326, Irgafos_168). The degradation of one additive was identified by NMR and GC-MS. Precise multiple-point quantification with internal standard was performed by GC-MS, measuring a 5.1 wt% Irgafos_168 degradation, with additives LOD ranging from 0.55-0.95 ppm. Evaluation of analytical challenges, such as matrix effects, was discussed and quantified. This method will help the quality control of virgin and recycled PS materials, including food contact ones, and improve the knowledge of PS processing impact on NIAS formation.

Published: November 2024

Numerous studies have demonstrated the ability of Ru complexes to inhibit the growth of various bacterial strains, including both Gram-positive and Gram-negative bacteria. A library of (η6-p-cymene)Ru (II) and Ru (II) bis-bpy bearing thiazolhidrazinylidene-chroman-2,4-dione was synthesized, characterized and all novel complexes were evaluated for their antibacterial activity, and cytotoxicity. From this library, many compounds were identified as being active, against Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA). A polypyridyl complex, 14, showed a remarkable minimum inhibitor concentration (MIC) of 3.12 µM and therapeutic index (T.I) of >32. We performed mechanism of action studies for several complexes. We could assign disruption of bacterial membrane integrity as a possible mode of action of piano stool arene species, while the mode of action of polypyridyl complexes remains elusive.

Published: November 2024

Direct C-F bond functionalization of readily accessible polyfluorinated compounds is an efficient strategy for constructing complex fluorine-containing molecules. While the controllable cleavage of C-F bonds with high chemoselectivity in perfluoroalkyl groups has been an unmet challenge, we report herein a switchable, substrate-controlled method for the cleavage of single C(sp³)-F bonds or double C(sp³)-F bonds using photocatalysis. By this chemodivergent strategy, a variety of valuable yet previously inaccessible fluorinated pyrroles and γ-lactams can be produced with high chemoselectivity. This method exhibits a broad substrate scope and excellent functional group tolerance. Mechanistic studies have been conducted to elucidate the reaction pathway.

Published: November 2024

Introduction. Modern wheeled vehicles are equipped with plug-in all-wheel drive control systems that increase their trafficability, stability and controllability. A good example is the AWD (All-wheel drive) system, which provides the highest efficiency of a plug-in drive compared to a permanent all-wheel drive. In order to ensure and maintain the efficiency and safety of vehicles with plug-in all-wheel drive control systems, it is necessary to investigate their functioning during manufacture and operation stages. Road testing methods are the most widespread methods for testing the systems under consideration. However they are not always feasible in the conditions of enterprises which provide testing and examination of vehicles, as well as in the conditions of service stations, service centers and other organizations of the automotive industry.

   Materials and methods. For the purpose of analytical research, a developed set of mathematical models containing the “ Vehicles “ and the “Stand” subsystems models was used. The description of the models is completed with the software package “Universal mechanism-9”. Experimental studies of operation of the vehicle with an automated AWD system were carried out on a full-support multifunctional stand with IRNIT running drums. The Volvo S60 25T AWD automobile with Haldex clutch of II generation was used as a research object.

   Results and discussion. In the course of analytical and experimental studies, the results of investigating vehicle operation were obtained by simulating acceleration with the slipping of the driving wheels of both the front and rear axles: the traction force on the driving wheels and the wheel speed.

   Conclusion. The results of this analytical research and their correspondence to the results of experimental study show the possibility of conducting qualitative and quantitative testing of automobiles with plug-in all-wheel drive control systems on roller test benches. The use of a complex of mathematical models will further allow for the development of unique bench methods and equipment to carry out research on the operational properties of modern vehicles.

The role of the state in contemporary processes of late-late development. A diagnosis of the Ethiopian experience to illustrate a renewed debate
Authors: Pérez-Lagüela Elena
Published: November 2024

Recent economic performance in Ethiopia has revived research on the role of the state in development processes. Assessing the relevance of the Ethiopian experience provides valuable insights to the discussion on the scope and limits of state action in other contemporary development experiences. This paper presents a case study based on elite interviews conducted during fieldwork in Ethiopia. The results of our research suggest that, while it is possible to argue that the Ethiopian state acquired developmentalist traits during the period 1994-2015, the characterisation of the state as «developmentalist» was used to sustain Meles Zenawi’s personalist political project. In Ethiopia, state-led development was not just an economic strategy aimed at structural transformation, but rather a means to maintain power.
Role and significance of the infrastructure component of investment in human capital of rural areas
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Ermolenko O.D.
Published: November 2024

In the modern world, the role of human capital in the stable development of the country’s agriculture is enormous. The problems of agricultural development cannot be solved only by improving the material factors of production. The development of the labor factor based on human resources is of great importance. In this regard, human capital can be considered as a key element for the successful development of agriculture. However, today there is a stable negative trend of the human capital outflow from rural areas, which only aggravates the difficulties of development of both rural areas and the agro-industrial sector. These problems lead to a decrease in the labor activity of the rural population, an increase in social dependency and an extremely low level of interest in the reforms carried out by the government in the agro-industrial sector. To overcome negative trends and sustainable development of agriculture, it is necessary to take comprehensive measures aimed at solving problems associated with the development of human capital in rural areas, it is necessary to expand and develop the infrastructure component of investment. The development of human capital in rural areas is a key factor in the sustainable development of agriculture and the agro-industrial sector. The aim of the study was to determine the role and significance of infrastructure investments in human capital in rural areas. The methods of logical and comparative analysis, systematization of information and processing of statistical data were used in the process of work. The article examines the main factors influencing the formation of human capital in rural areas. Among the most acute problems are the lack of systematic and comprehensive implementation of investment programs and state support for the development of rural areas, as well as differences in the level and quality of life of the rural and urban population. The work emphasizes the need for active participation of entrepreneurs in the development of human capital in agriculture for the sustainable development of rural areas.

Achieving the priorities of ensuring the country’s food security, expanding the export potential of agriculture, as well as maintaining economic stability and social development under sanctions directly depends on the nature and effectiveness of reproduction processes in agriculture. During the sanctions the importance of reproduction in Russian agriculture increases, as the demand for domestic products increases due to the decrease in imports, there is a need to switch to domestic seeds, components and other resources. It is the expanded reproduction that provides agriculture with additional investment resources that can be directed to the development of the industry. To solve the problem of import substitution it is necessary to stimulate expanded reproduction in agriculture through the development and implementation of domestic breeding achievements, high-tech technologies, personnel training, and digitalization of the industry. The article analyzes the reproduction processes in Russian agriculture for the sanctions period from 2014 to 2022 on the basis of assessing the dynamics of key indices of agricultural production and reproduction factors; the nature of the dynamics of agricultural production is studied and the trend of development of this indicator is revealed; the characteristic of the reproduction processes and their effectiveness over time periods are characterized. The results of the study have shown that Russian agriculture, in the period of sanctions pressure adapts quite successfully to the external environment and with a certain improvement in the conditions of the reproduction process can not only maintain the existing trend, but also develop at a faster pace. For this purpose, it is necessary to provide the industry with sustainable investments that reduce imports of agricultural products, increase labor productivity, intensify production, attract qualified labor resources, and greenize production. As research methods, the article uses special statistical methods such as modeling the trend of a time series, analytical alignment and the moving average method, analysis of autocorrelation functions, construction of correlation and regression models, nonlinear dynamic models, etc.

The review presents information on the biocontrol potential of antagonist bacteria of the genera Bacillus, Pseudomonas and Streptomyces against toxin-producing fungi Fusarium. The harmfulness of Fusarium fungi species complex is that it not only affects grain, reducing the content and quality of protein, its final weight, but also causes contamination with mycotoxins. The ability of fungi of the genus Fusarium to produce mycotoxins is an important factor in the pathogenicity of fungi. Information on the toxicity of deoxynivalenol and zearalenone for humans and animals is presented. Bacteria of the genera Pseudomonas, Bacillus, Streptomyces spp. show antagonistic activity against fungi of the genus Fusarium. In agroecosystems, the most extensive research on bacterial agents for the control of phytopathogenic fungi has focused on antibiosis. The bacteria secrete lipopeptide antibiotics, phenazine derivatives, and other antifungal metabolites to directly inhibit F. graminearum. In addition, beneficial bacteria destroy fungal virulence factors, produce volatile antifungal compounds, and induce systemic plant resistance to phytopathogenic fungi. Biological control mechanisms (antibiosis, competition, hyperparasitism and induced resistance) can act simultaneously, resulting in disease control and therefore reduced mycotoxin contamination. This knowledge facilitates the targeted isolation of bacteria identified as microbiological agents for the biocontrol of phytopathogenic fungi. Understanding the molecular and biochemical basis of biocontrol will facilitate the development of more potent producers of effective biocontrol agents and a better understanding of the mechanisms of biocontrol activity.

Recently, along with the determination of physical and chemical pollution in establishing the quality of surface waters and especially river ecosystems, the biological and, first of all, the hydrobiological component has become increasingly important. The purpose of this work was to assess the ecological quality of river ecosystems in specially protected natural areas of Belarus and Uzbekistan based on the study of the macrozoobenthos community.

Alien, rare for Belarus and protected in Europe, species of aquatic organisms were identified at the model stations.

In the territory of the both states, a high abundance (from 30 to 80 %) of rheophilic species Plecoptera, Ephemeroptera and Trichoptera, which represent the three most priority indicator groups of aquatic organisms, was noted. Biotic indices were determined and the class of water purity of the rivers of the State landscape reserve “Srednyaya Pripyat”in Belarus and the Ugam-Chatkal State Natural National Park in the territory of Uzbekistan were calculated. In accordance with the EU Water Framework Directive, the ecological water quality at the studied sampling sites can be classified as good and high water purity classes in the territory of the both countries.

The mechanical behavior and structure formation of sheet specimens of the titanium alloy Ti–6Al–4V is studied. Low strain rate (quasi-static) deformation at ἐ = 0.001, 0.01, 0.1 and 1 s–1 is compared with fast (dynamic) deformation performed using the Hopkinson method with ἐ = 1290, 2066, 3567, and 3828 s–1. The features of the structure formation mechanism of the titanium alloy Ti–6Al–4V under high-strain-rate (≈3800 s–1) deformation have been determined, namely that along with the dislocation glide, the twinning develops, the characteristics of texture present in the original sheet material undergo changes, plastic deformation occurs throughout the entire volume of the α-phase and β-phase grains (while in the quasi-static mode, mainly plastic deformation of the α-phase grains takes place), dislocation pile-ups and cells inside the grains are formed, which points to intensive interaction of dislocations. The established mechanisms lead to a substantial increase in technological plasticity of the titanium alloy during impact hydroforming as compared to quasi-static deformation.
