Harmonization of the definition of insecticidal substances for the purposes of production control and monitoring of finished compositions. III. Gel-like insecticidal compositions
Authors: Носикова Л.А. , Кочетов А.Н.
Published: August 2024

На примерах конкретных инсектицидных средств рассмотрены возможности гармонизации анализа гелеобразных композиций. В качестве основного инструмента для определения объектов на сложнейших пищевых матрицах рассмотрен метод ОФ ВЭЖХ. Лишь в некоторых случаях целесообразно его дополнить методом ГЖХ. Продемонстрирована возможность одновременного определения 10 субстанций разных классов, а также примеры анализа гелеобразных инсектицидных средств с действующими веществами на основе производных неоникотиноидов (имидаклоприд, ацетамиприд), пиретроидов (альфациперметрин), фенилпиразолонов (фипронил), оксадиазинов (индоксакарб), аминогидразонов (гидраметилнон) и ФОСов (фентион, диазинон, хлорпирифос). Рассмотрены сложности при проведении пробоподготовки. Предложенные подходы позволяют относительно быстро выработать аналитический метод контроля гелеобразных композиций с учетом рассмотренных в предыдущих частях рекомендаций по созданию методик для широкого круга инсектицидных субстанций, использующихся в практике пест-контроля.

Using examples of specific insecticidal agents, the possibilities of harmonizing the analysis of gellike compositions are considered. The method of HPLC is considered as the main tool for determining objects on the most complex food matrices. Only in some cases it is advisable to supplement it with the GC method. The possibility of simultaneous determination of 10 substances of different classes has been demonstrated, as well as examples of gel-like insecticidal agents of neonicotinoid derivatives (imidacloprid, acetamiprid), pyrethroids (alphacypermethrin), phenylpyrazolones (fipronil), oxadiazines (indoxacarb), aminohydrazones (hydramethylnone) and phosphates (fentione, diazinone, chlorpyrifos). The difficulties in carrying out sample preparation are considered. The proposed approaches make it possible to develop an analytical control method relatively quickly with the possibility of harmonization, taking into account the recommendations discussed in the previous parts on the creation of methods for a wide range of insecticidal substances used in the practice of pest control.

Published: August 2024

Земноводные (Amphibia) и пресмыкающиеся (Reptilia) – обособленная группа факультативных пест-животных. Наиболее опасная угроза для человека – отравление их ядами. В последнее время все более актуальными становятся такие формы их нежелательного воздействия, как создание негативного эмоционального фона и ущерб от инвазивных видов. Ряд биологических особенностей низших четвероногих, в первую очередь, пойкилотермность и биотопическая детерминированность распространения и перемещений, а также их специфическое поведение, определяют развитие современных методов их пест-контроля. Все более существенную роль в современном пест-менеджменте земноводных и пресмыкающихся выполняют технические решения по предотвращению проникновения этих объектов на защищаемые территории, а также методология формирования непривлекательной или неприемлемой для них среды.

Amphibians and Reptiles are special and distinct objects in the modern pest management. Traditionally the most important threat of the animals is poisoning (bytes or skin secrets). Relatively new challenges are the negative emotional impact as well as diverse risks of alien species. Several biological peculiarities such as poikilothermy or biotopic restrictions determine actual approaches of herpetological pest management. Trapping technics and bait uses are improving. At the same time methos of penetration restrictions are in progress especially environment transformation in a mode unacceptable for amphibians and reptiles. Very important aspect of the herpetological pest managements is that near all the species are objects of priority wild life conservation

METHODS OF PRESENTING THE WORKS OF RUSSIAN COMPOSERS TO CHINESE AUDIENCES (THE CASE OF B. A. TCHAIKOVSKY)
Authors: YANG ZH.
Published: August 2024

The article is devoted to the problem of introducing the musical heritage of B. A. Tchaikovsky into the education of Chinese music students. The insufficient number of theoretical works representing a multifaceted creative portrait of the composer and music collections do not contribute to the spread of his musical opuses in China. However, getting to know the work of this unique and relatively modern composer will be very useful for Chinese performers. His highly artistic music with an original intonation language, created in line with the best traditions of the Russian school of composition, can increase the level of performing culture of Chinese students at all levels of education. That is why this topic is relevant and requires further development. The article also presents the potential of various information and communication technologies that can be used in lectures and practical classes on the study of B. A. Tchaikovsky's work, including digital tools such as Ultimate Music Theory, Easy Xylophone and Magic Tiles Games.

Published: August 2024

The questions on long-term planning of an enterprise’ bonded loan interest rate payments have been studied. The methods have been considered and the classification of methods for planning the bonds interest rate proposed. Several groups of such planning methods have been singled out. The analysis of application of bond interest rate planning methods applied by enterprises of different national industries has been made. The analysis has been carried out in the spheres of mechanical engineering, generation, transmission and sales of electric power, ferrous metals production, transportation and logistics, foodstuffs production, and information transmission provision. Corporate bond issues issued between 2015 and 2020 have been analyzed. As a result, the three methods most frequently used by enterprises in planning bond interest rates have been identified: methods of considering the macroeconomic risk of an organization; methods of considering the combination of macroeconomic and individual risk of an organization; methods based on market analysis. The study of the mentioned methods allowed us to propose a method of planning the bond interest rate, which calculates the weighted average of the forecast bond interest rate. To assess the quality of the proposed method, it has been tested. The article concludes that it can be used at enterprises planning to issue their own bonded loans.

Published: August 2024

The article studies main socio-cultural resources that ensure the success of the management strategy of modern China. The Law “On Public Service” is considered as an important legal resource regulating the activities of public personnel. Since the social stability of the Chinese society is explained by the multiparty political system of the country with the leading role of the Communist Party of China, the article presents a table compiled by the author about the parties, including the logo, information about the leaders and their education, data on the degree of influence of each party in society and its establishment time. The possibility of consultations with the participation of all officially operating parties guarantees the Communist Party of China the adoption of a theoretically grounded plan for ongoing reforms implementation, which is interpreted as an important managerial resource along with personnel policy. The socio-cultural vector of the management strategy is interpreted in the discourse of the building socialism theory with Chinese specifics, which implies the living standards improvement with industries development that provide vital human needs and socially important innovation directions in science and economy. The author concludes that the management strategy resources have a multi-vector character, which is manifested in economic and cultural, scientific and technological, political and ideological spheres.
The phenomenon of procrastination
Authors: Kochetkova T. N.
Published: August 2024

Procrastination is one of the most researched and polemized topics of interest to domestic and foreign scientists due to its widespread prevalence among students and adults. The authors agree that syste matic violation of deadlines for necessary tasks completion causes subjective discomfort, but this behavior is regularly manifested in ordinary life, becoming “chronic” in nature.

   The purpose of the study is to analyze the phenomenon of procrastination.

   The work was based on the theoretical analysis of literature, generalization, empirical research results interpretation, conducted on the basis of a bank of techniques: E. Yu. Mandrikova’s questionnaire of self-organization of activity, K. Lay’s academic procrastination scale, Melbourne questionnaire of decision-making in the adaptation of T. V. Kornilova and S. A. Kornilova. Procrastination is similar to manifestations of laziness, low level of motivation and volitional self-regulation, awareness of the consequences of one’s own inaction, behavioral patterns repetition stability. However, thereare cardinal differences among them: laziness correlates with neutral or positive emotional background, hedonistic orientation, orientation to the present time, irresponsibility, and strength saving. Procrastination is built on burdensome experiences, mental immersion in the events of the past or future. It is energy-consuming, can lead to ideas destruction about one’s own personality and chronic diseases. Negative emotional background, weak self-control and low self-regulation are all prerequisites for developing procrastination and dependence on digital reality. The study results can be applied in the activities of teachers and practical psychologists, allowing to recognize and level procrastination manifestations.

Solution-Phase Synthesis of Alloyed Ba(Zr1-xTix)S3 Perovskite and Non-Perovskite Nanomaterials
Authors: Zilevu Daniel , Miller Kennedi , Arrykova Naira , Locke Autumn , Creutz Sidney
Published: August 2024

Chalcogenide perovskites, especially BaZrS3 and its related alloys, present a promising alternative to lead halide perovskites for optoelectronic applications due to their reduced toxicity and enhanced stability. However, the elevated temperature conditions necessary for preparing these materials create a barrier to their incorporation into thin-film devices. In this work, we report a solution-phase synthesis of colloidal nanoparticles of titanium-alloyed BaZrS3, Ba(Zr1-xTix)S3. The titanium alloying was achieved using reactive amide precursors in oleylamine solvent, and N,N'-diethylthiourea served as the sulfur source. Our methodology allowed for the synthesis of Ba(Zr1-xTix)S3 nanomaterials at temperatures at or below 300 oC. The resulting nanocrystals exhibited a phase transition from an orthorhombic distorted perovskite structure to a hexagonal non-perovskite phase as the Ti content surpassed x = 0.11, accompanied by a morphological evolution from nanoplatelets to nanohexagons and ultimately nanobars. The UV-Vis-NIR absorption spectra of BaZr1-xTixS3 nanoparticles exhibit increasing low-energy absorption as the Ti4+ content is increased. This work contributes to the development of low-temperature synthesis methods for Ba(Zr1-xTix)S3 nanomaterials, offering new potential pathways for materials design of chalcogenide perovskites for advanced optoelectronic applications.
Thermodynamic modeling of complex solid solutions in the Lu-H-N system via graph neural network accelerated Monte Carlo simulations

Published: August 2024

Metal hydrides are important across diverse applications such as hydrogen storage, batteries, gas sensors, nuclear reactions and high-temperature superconductivity. Previous computational studies of metal hydrides under extreme pressures, e.g., O(10^2) GPa, usually treat them as stoichiometric compounds without considering interstitial lattice disorder. As pressures become more moderate in the O(10^0) GPa and below range, hydrogen disorder at interstitial lattice sites becomes prominent, e.g. in the N-doped Lu hydride that was recently claimed superconducting near 1 GPa. Further adding compositional complexity from alloying and/or multi-element interstitial occupation makes elucidating pressure- and temperature-dependent observables intractable by first-principles calculations alone. We therefore propose a lattice graph neural network surrogate modeling approach to predict configuration- and pressure-dependent equation-of-state properties. Their efficiency permits Monte Carlo simulations to calculate Gibbs energies and pressure-dependent phase diagrams, thereby revealing insights into the synthesis conditions required for achieving desired phase equilibria. We demonstrate this concept for the compositionally complex cubic Lu(H, N,Va)3 system where three constituents (hydrogen, nitrogen and vacancy) have disordered multi-element interstitial occupancies and insights into pressure-dependent phase equilibria are critically needed, e.g., N-doping levels can significantly lower dehydrogenation temperatures and provide a new strategy to optimize hydrogen-storage alloys. This work can improve the thermodynamic understanding of the Lu-H-N system and help rational synthesis of N-doped Lu hydrides, but more generally demonstrates an efficient approach to model pressure-dependent thermodynamics of multi-component solid solutions.

Published: August 2024

We collected paired measurements of indoor and outdoor PM2.5 concentrations at 17 homes in Dhaka, Bangladesh, to quantify indoor-outdoor levels, their spatio-temporal variations, and influencing factors. A pair of PurpleAir PM2.5 sensors were deployed at each home, one indoors and the other outdoors, during the wet (June to August 2021) and dry (December 2021 to February 2022) seasons, and the locally calibrated (against a beta attenuation monitor) and quality-assured data were used for analysis. Indoor and outdoor PM2.5 levels were three times higher during the dry season (indoor 146 ± 22 µg/m³, outdoor 153 ± 23 µg/m³) than during the wet season (indoor 52 ± 12 µg/m³, outdoor 50 ± 11 µg/m³). Indoor to outdoor (I/O) ratios were close to 1 in both seasons (dry: 0.97 ± 0.14, wet: 1.05 ± 0.19). This suggests that regional background pollution levels significantly influence indoor levels observed in different households. Higher infiltration factors (dry: 0.83 ± 0.12; wet: 0.87 ± 0.14), determined through mixed effect regression of parallel indoor and outdoor timeseries data, further highlight the substantial impact of outdoor pollution on indoor levels. Data from individual households exhibited strong temporal correlation between indoor and outdoor levels in both seasons (Pearson R: 0.82 ± 0.12 during the dry season and 0.83 ± 0.14 during the wet season), whereas indoor-outdoor spatial correlations across measured households were moderate (R: 0.49 and 0.62 during dry and wet seasons, respectively). These spatial correlations and empirical regression modeling suggest that while the spatial variation of outdoor PM2.5 levels significantly influences indoor levels' spatial variation, other factors such as indoor source activities and ventilation-related features play crucial roles in explaining variabilities in indoor PM2.5 across homes. Overall, our study suggests that indoor environments in Dhaka city are nearly as polluted as outdoor settings, and this locally derived scientific evidence can be valuable for enhancing public awareness and developing mitigation measures to reduce PM2.5 exposures in Bangladesh.
Distinguishing Surface and Bulk Reactivity: Concentration Dependent Kinetics of Iodide Oxidation by Ozone in Microdroplets
Authors: Prophet Alexander , Polley Kritanjan , Brown Emily , Limmer David , Wilson Kevin
Published: August 2024

Iodine oxidation reactions play an important role in environmental, biological, and industrial contexts. The multiphase reaction between aqueous iodide and ozone is of particular interest due to its prevalence in the marine atmosphere and unique reactivity at the air-water interface. Here, we explore the concentration dependence of the I- + O3 reaction in levitated microdroplets under both acidic and basic conditions. To interpret the experimental kinetics, molecular simulations are used to benchmark a kinetic model, which enables insight into the reactivity of the interface, the nanometer-scale sub-surface region, and the bulk interior of the droplet. For all experiments, a kinetic description of gas- and liquid-phase diffusion is critical to interpreting the results. We find that the surface dominates the iodide oxidation kinetics under concentrated and acidic conditions, with the reactive uptake coefficient approaching an upper limit of 10-2 at pH 3. In contrast, reactions in the sub-surface dominate under more dilute and alkaline conditions, with inhibition of the surface reaction at pH 12 and an uptake coefficient that is 10x smaller. The origin of a changing surface mechanism with pH is explored and compared to previous ozone-dependent measurements.
Mechanistic Exploration of N-Heterocyclic Carbene Boranes as the Hydrogen Atom Transfer Reagent in Selective Hydro-defluorination Reactions
Authors: Jaiswal Amit Kumar , Skjelstad Bastian Bjerkem , Maeda Satoshi , Huang Chung-Yang Dennis
Published: August 2024

In the modern era of organic synthesis, mechanisms centering on radical intermediates have become increasingly impact-ful in unlocking novel reactivity. Among all, hydrogen atom transfer (HAT) represents one of the most fundamental chemical reaction steps and has found applications in designing practical transformations. Herein, we present a detailed case study on selective hydrodefluorination of trifluoromethylarenes utilizing N-heterocyclic carbene boranes (NHC-boranes) as the HAT donor. Under the optimal conditions featuring an acridine-based photocatalyst, complete selectivity for mono-hydrodefluorination was achieved across a wide array of substrates. Comprehensive mechanistic studies com-bining experimental and computational approaches disproved a chain process involving a fluorine atom transfer but ra-ther pointed to a HAT non-chain mechanism, where the key step involves the difluorobenzylic radical abstracting a hy-drogen atom from the NHC-borane to generate a boryl radical in a polarity-matched fashion. Evaluation of a selection of Lewis base-ligated boranes revealed molecular descriptors critical to the outcomes of this reaction, and a classification model is built to explain the structure-reactivity relationship and how various elementary steps can be influenced. These results collectively provide valuable information for future reaction design to elevate the utility of boranes in organic radical chemistry.

Published: August 2024

Protecting sensitive medical data, including prescription and pill data, during its handling and storage is critical in the digital era. Data vaults that protect privacy provide a strong way to protect this information, guaranteeing that patient information is kept private but yet available for authorised uses. Focussing on the safe preservation of pharmaceutical data, this project investigates the creation of sophisticated algorithms for privacy-preserving data vaults. We start by contrasting the suggested innovative technique, which combines elements of Zero-Knowledge Proofs with Enhanced Homomorphic Encryption, with other known cryptographic and data masking algorithms, such as Differential Privacy, Secure Multi-Party Computation, and Homomorphic Encryption. Data integrity, computational efficiency, and resistance to different attack vectors are some of the characteristics used in the comparison.As the results show, the suggested method offers aimproved performance against confidentiality compromises, especially in real-time data retrieval scenarios, while existing techniques offer varied degrees of efficiency and security. But this comes with more implementation complexity and processing overhead. Improved security characteristics, like less data leakage and strong user authentication systems, are benefits of the suggested approach. Large-scale applications may experience latency problems and require more powerful hardware, which are drawbacks.The trade-offs between various data privacy strategies are highlighted in this study, and it also highlights the necessity for on-going innovation in privacy-preserving technology, which makes a contribution to the region.

Reviving the Proposal For a Parliamentary Budget Officer
Authors: Ball Ian , Irwin Tim , Scott Graham
Published: August 2024

The 2019 proposal that New Zealand create a parliamentary budget officer should be revived, but with certain changes. First, the parliamentary budget officer should not be asked to estimate the cost of political parties’ electoral platforms, since that is not a proper function of an officer of Parliament, and the political sensitivity and resource intensiveness of such costings could interfere with the officer’s ability to help Parliament hold the executive to account. Second, the parliamentary budget officer should have a broader scope to comment on public finances than was envisaged in 2019. Third, the creation of a parliamentary budget officer should be accompanied by consideration of other ways of strengthening Parliament’s effectiveness in scrutinising public finances, such as having a member of the opposition chair the Finance and Expenditure Committee.

The Ka Ora, Ka Ako school lunch programme introduced in 2020 provides nutritious lunches to around 220,000 students in low-advantage schools. While the food security impacts of this programme have been well documented, its potential to enhance outcomes in other areas of public policy is underappreciated. We conducted a policy analysis to map the programme’s intersection with current public policy agendas in education, sustainability and health in Aotearoa New Zealand. We conclude that Ka Ora, Ka Ako can be a powerful platform to effect broad societal outcomes through alignment with school curricula, concerted effort to reducecarbon emissions, and commitment to delivering highly nutritious foods to all students in qualifying schools.

Pemilihan peminatan konsentrasi adalah hal yang wajib dilakukan oleh mahasiswa S1 Pendidikan Teknologi Informasi pada semester 5. Pada pemilihan peminatan konsentrasi tidak ada ketentuan resmi karena hanya berdasarkan minat dari mahasiswa dan tidak sedikit mahasiswa yang kebingungan pada saat akan memilih bidang minat yang mereka inginkan. Maka dari itu, tujuan penelitian ini adalah memberikan pertimbangan guna mendukung keputusan mahasiswa dalam menentukan bidang minat konsentrasi yang akan diambil berdasarkan nilai akademik dari mata kuliah yang menjadi dasar dari pemilihan konsentrasi. Dalam penelitian ini algoritma yang digunakan yaitu Naive Bayes dan akurasi yang didapatkan yaitu 100%. Hasil pengujian sistem yang dibuat menggunakan pengujian blackbox testing dan validasi oleh ahli media yaitu oleh dua dosen Teknik Informatika Universitas Negeri Surabaya, hasil blackbox testing menunjukkan bahwa sistem pendukung keputusan yang telah dibuat berhasil dan berjalan sesuai dengan hasil yang diharapkan dan hasil dari validasi dari ahli media yaitu validator pertama mendapatkan hasil persentase 90% dan validator kedua 82 % keduanya menunjukkan hasil persentase yang tinggi sehingga dari hasil tersebut dapat disimpulkan bahwa sistem pendukung keputusan menggunakan algoritma Naive Bayes berhasil dan bisa digunakan.
