Authors: Колмогорова С.С. 
Published: January 2024

Для обеспечения безопасной и стабильной работы любой энергосистемы, необходимо постоянно контролировать и обслуживать оборудование и линии электропередач, находящиеся под напряжением. В зависимости от условий эксплуатации, необходимо анализировать электрические поля, которые не всегда являются однородными. Для анализа распределения заряда на сенсорные элементы заряда различной формы при воздействия электрического поля в статье представлена имитационная модель. Беря в расчет пространственное распределение электрического поля, неоднородность исследуемого поля, и накопление поверхностного заряда на датчик была получена количественная связь измеряемого электрическим полем и конечными результатами измерения. Результаты моделирования показывают высокую точность при оценке взаимосвязи между составляющими электрического поля для различных форм сенсорных элементов и хорошо согласуются с результатами анализа, полученными методом конечных элементов.
To provide safe and stable operation of any power system, it is necessary to constantly monitor and maintain energized equipment and transmission lines. Depending on the operating conditions, it is necessary to analyze electric fields, which are not always homogeneous. In order to analyze the charge distribution on differently shaped sensing elements under the influence of electric field, a simulation model is presented in this paper. By taking into account the spatial distribution of the electric field, the inhomogeneity of the field under study, and the accumulation of surface charge on the sensor, a quantitative relationship between the measured electric field and the final measurement results was obtained. The simulation results show high accuracy in evaluating the relationship between the electric field components for different forms of sensor elements and agree well with the analysis results obtained by finite element method.

В работе рассмотрены известные на данный момент фильтры изображений, относящиеся к разным классам для выявления особенностей при устранении шума с изображений, полученных с помощью метода активного формирования спектральных изображений с помощью гиперспектральных данных. Для этого были применены низкочастотный, высокочастотный, Гауссов, медианный, средний, нерезкий, консервативный, Лапласовский, удаление пятен Кримминса, двусторонний и плоский фильтры на изображения, полученные на одной длине волны лазерного излучения, одного вещества, но различных подложках, для выбора оптимального фильтра, в случаях сохранения полезного сигнала, эффективности фильтрации при различных подложках и удаления шума и выделения вещества на изображении. Так же были получены амплитудно-частотные характеристики полученных изображений после фильтрации для получения критериев выбора оптимального фильтра.
The paper considers currently known image filters belonging to different classes to identify features when eliminating noise from images obtained using the method of active spectral image formation using hyperspectral data. For this purpose, low-frequency, high-frequency, Gaussian, median, medium, blurred, conservative, Laplace, Crimmins stain removal, two-sided and flat filters were applied to images obtained at the same wavelength of laser radiation, of the same substance, but on different substrates, to select the optimal filter, in cases of preservation of a useful signal, filtration efficiency at various substrates and the removal of noise and the release of matter in the image. The amplitude-frequency characteristics of the images obtained after filtering were also obtained to obtain criteria for choosing the optimal filter.

Реакцией нуклеофильного гетероциклического замещения (SNipso-замещения) нитрогруппы в молекуле субстрата – 1-метил-5-нитро-1,2,4-триазола с участием пропаргилового спирта, как О-нуклеофильного агента, синтезировано новое функционализированное триазоловое производное – 1-метил-5-проп-2-инилокси-1Н-[1,2,4]триазол. Найдены условия взаимодействия 1-метил-5-нитро-1,2,4-триазола с пропаргиловым спиртом, обеспечивающие конверсию субстрата более 98 %. Доля продуктов конкурентных реакций – 1-метил-1,2,4-триазол-5-она и N-С триазолилтриазолона составляет 7,5 % и 0,9 % соответственно. Структура полученного алкинового производного надежно подтверждена комплексным анализом с помощью спектроскопического метода ЯМР: протонного магнитного резонанса (1Н ЯМР-спектроскопия) и спектроскопии ЯМР на ядрах углерода (13С ЯМР-спектроскопия). Методом ДСК изучены термические характеристики. Благодаря наличию функциональной алкиновой группы полученное соединение представляет интерес для использования его в качестве диполярофила в реакциях 1,3-диполярного циклоприсоединения, так как это позволит аккумулировать в одной молекулярной структуре полезные свойства как симметричного 1,2,4-триазола, так и образующегося в ходе реакции вицинального 1,2,3-триазола.A new functionalized triazole derivative, 1-methyl-5-prop-2-ynyloxy-1Н-[1,2,4]triazole, was synthesized by the reaction of nucleophilic substitution (SNipso-substitution) of the nitro group in the molecule of substrate 1-methyl-5-nitro-1,2,4-triazole, involving propargyl alcohol as an О-nucleophilic agent. The interaction conditions between 1-methyl-5-nitro-1,2,4-triazole and propargyl alcohol, which ensure a substrate conversion of more than 98%, were found. The proportions of the competitive reaction products, 1-methyl-1,2,4-triazol-5-one and an N-С bicycle, were 7,5 and 0,9%, respectively. The structure of the resultant alkyne derivative was credibly confirmed by a combined analysis using NMR spectroscopy, such as proton magnetic resonance (1Н NMR spectroscopy) and NMR spectroscopy on carbon nuclei (13С NMR spectroscopy).The thermal behavior was characterized by the DSC technique. Because of the presence of the functional alkyne group, the resultant compound is appealing for use as a dipolarophile in 1,3-dipolar cycloaddition reactions, as this will allow a single molecular structure to accumulate useful properties of both symmetric 1,2,4-triazole and vicinal 1,2,3-triazole resulting from the reaction.

В настоящее время бор рассматривается в качестве перспективного компонента взрывчатых составов благодаря высокой теплоте сгорания, что может значительно повысить фугасность взрывчатых веществ по сравнению с обычно используемыми добавками алюминия. Однако существуют противоречивые данные относительно эффективности применения бора. В работе проведены исследования по определению условий, позволяющих реализовать положительный эффект от замены алюминия на бор во взрывчатых составах с целью повышения их фугасности. В результате проведенных исследований определены особенности работоспособности боросодержащих взрывчатых составов. Показано, что необходимо соблюдать определенный баланс между массовым содержанием взрывчатого компонента и бора, при котором наблюдается значительное повышение фугасности.Currently, boron is considered as a promising component of explosive compositions due to its high combustion heat, which can significantly increase blasting power of explosives compared to commonly used aluminum additives. However, there are conflicting data regarding the efficiency of the boron use. In this work, the studies were carried out to determine the conditions that make it possible to realize the positive effect of replacing aluminum with boron in explosive compositions in order to increase their blasting power. As a result of the implemented research, the features of the performance of boron-containing explosive compositions were determined. It was shown that it is necessary to maintain a certain balance between the mass content of an explosive component and boron, wherein a significant increase in blasting power is observed.

Entre arrogance et microagression linguistiques
Authors: Arrighi Laurence 
Published: January 2024

Dans cette contribution, je propose l’interprétation d’une réaction individuelle face à des pratiques de marquage du discours rapporté utilisées dans des médias en milieu linguistique minoritaire (l’apposition à la suite de propos présentant des particularismes linguistiques locaux d’un (sic) ainsi que divers marquages métadiscursifs type « nous dit-il avec son charmant accent acadien »). Une recherche systématique au sein d’un corpus montre que ces pratiques sont notables bien que peu courantes. Ces pratiques relèvent sans doute de techniques professionnelles bien établies. Il n’en demeure pas moins qu’elles peuvent s’avérer indélicates envers la communauté que ces médias desservent ce dont témoigne la réaction individuelle que je prends comme point de départ. Je propose que l’on peut voir dans ces pratiques une forme d’arrogance linguistique (Messaoudi 2021) constituant une micro-agression linguistique (Razafimandimbimanana et Wacalie 2020) de plus auxquelles font face les minorités linguistiques.

Published: January 2024

Purpose: This study sought to assess the efficacy of bid disputes management mechanism in Kenya.

Theoretical Framework: Transparency in public procurement proceedings is a concern for most stakeholders. Allowing aggrieved bidders to challenge decisions of procuring entities is considered a critical development in the space of public procurement. The effectiveness and efficiency of bid disputes management mechanism should therefore be a concern for procuring entities, bidders, and development partners especially. This aspect is yet to be explored extensively in Africa.

Design/Methodology/Approach: The Methodology for Assessing Procurement Systems (MAPS) as propagated by the Organisation for Economic Co-operation and Development (OECD) helps evaluate the quality of public procurement systems and subsequently strategize on necessary reforms. This study applied MAPS to assess the efficacy of the bid disputes management mechanism in Kenya.

Findings: It was established that overall, the public procurement bid dispute management mechanism in Kenya was effective and efficient. However, shortcomings were noted concerning resourcing of Public Procurement Administrative Review Board (PPARB), unaffordable filing fees and accessibility of comprehensive, simple, and clear information on filing procedures.

Research, Practical and Social Implications: The findings of this study offer policy recommendations that will help promote effective and efficient management of public procurement bid disputes.

Originality/Value: The results of this study contribute to theory, practice and literature in the field of public procurement which is less researched in the Eastern Africa Region. The findings of the study can be replicated in countries that have based their procurement reforms on the United Nations Commission on International Trade Law (UNCITRAL) Model Law on Public Procurement. It is to be appreciated that application of MAPS indicators allows for subjective judgments by the assessor.

A microbacia do igarapé do Irurá pertence a bacia hidrográfica do Rio Tapajós, e está localizada na cidade de Santarém- PA, no Oeste do Pará. A cidade, não possui uma rede de saneamento básico adequado, que faz com que boa parte do esgoto doméstico e industrial seja lançado in natura, em igarapés e no rio Tapajós, afetando diretamente as condições da biota aquática, como o pescado, que é parte da dieta alimentar e renda da região. O objetivo desta pesquisa foi a caracterização geoquímica dos sedimentos superficiais da microbacia do igarapé do Irurá. As coletas de sedimentos foram realizadas em cinco pontos amostrais, desde a nascente do igarapé Irurá até próximo à foz, entre os anos de 2020 e 2021. Foram mensurados parâmetros físico-químicos, como: pH em Água e em cloreto de Potássio (KCl), acidez potencial, capacidade de troca de cátions (CTC), soma de bases (SB), saturação em bases (V), matéria orgânica (M.O), sulfato, fósforo total (PT), metais (Al,Cr, Cu, Fe, , Mn e Zn). Foi aplicado o teste estatístico de Análise de Principal de Componente (APC). Os resultados mostraram que a textura do sedimento foi caracterizada por arenosa, além disso, as concentrações dos contaminantes foram maiores na estação seca. A APC mostrou correlações diferentes entre seca e chuva, o que pode estar relacionado à sazonalidade. As maiores concentrações de contaminantes na estação seca, indica que pode ter uma transferência dos contaminantes para a coluna d’água, devido aos processos naturais de ressuspensão do sedimento, o que aumenta o risco para biota aquática. Diante disso, é necessário que ampliem os estudos sobre a contaminação de recursos aquáticos amazônicos, principalmente, em áreas urbanas, onde a taxa de degradação dos recursos hídricos é mais rápida.
