A single-particle plasmon sensor to monitor proteolytic activity in real-time
Authors: Oliveira-Silva Rui , Wang Yuyang , Nooteboom Sjoerd , F. Prazeres Duarte M. , R. Paulo Pedro M. , Zijlstra Peter
Published: June 2023

We have established a label-free plasmonic platform that monitors proteolytic activity in real-time. The sensor consists of a random array of gold nanorods that are functionalized with a design peptide that is specifically cleaved by thrombin resulting in a blue-shift of the longitudinal plasmon. By monitoring the plasmon of many individual nanorods we determined thrombin’s proteolytic activity in real-time and inferred relevant kinetic parameters. Furthermore, comparison to a kinetic model revealed that the plasmon shift is dictated by a competition between peptide cleavage and thrombin binding, which have opposing effects on the measured plasmon shift. The dynamic range of the sensor is greater than two orders of magnitude, and it is capable of detecting physiologically relevant levels of active thrombin down to 3 nM in buffered conditions. We expect these plasmon-mediated label-free sensors open the window to a range of applications stretching from diagnostic and characterization of bleeding disorders to fundamental proteolytic and pharmacological studies.

Published: June 2023

Main-group compounds that can mimic the behavior of the transition-metal (TM) complexes are of great interest due to their potential in TM-free catalysis. Here, we report the synthesis, isolation and full characterization of the geometrically constrained phosphenium cation with the 2,6-bis(o-carborano)pyridine pincer-type ligand. A preliminary reactivity study showed that this cation is capable of activating H−H bond by a formal oxidative addition to PIII cationic center, which is unprecedented reactivity for PIII-centers, producing new dihydrophosphonium cation. Remarkably, this new phosphenium cation is capable of catalyzing the hydrogenation reactions of C=C double bonds and fused aromatic systems.

THE INFLUENCE OF NLU AND GENERATIVE AI ON THE DEVELOPMENT OF CYBER DEFENSE SYSTEMS
Authors: Sukaylo Igor , Korshun Nataliia
Published: June 2023

The combination of cyber security systems and artificial intelligence is a logical step at this stage of information technology development. Today, many cybersecurity vendors are incorporating machine learning and artificial intelligence into their products or services. However, the effectiveness of investments in advanced machine learning and deep learning technologies in terms of generating meaningful measurable results from these products is a matter of debate. When designing such systems, there are problems with achieving accuracy and scaling. The article considers the classification of artificial intelligence systems, artificial intelligence models used by security products, their capabilities, recommendations that should be taken into account when using generative artificial intelligence technologies for cyber protection systems are given. ChatGPT's NLP capabilities can be used to simplify the configuration of policies in security products. An approach that considers both short-term and long-term metrics to measure progress, differentiation, and customer value through AI is appropriate. The issue of using generative AI based on platform solutions, which allows aggregating various user data, exchanging ideas and experience among a large community, and processing high-quality telemetry data, is also considered. Thanks to the network effect, there is an opportunity to retrain AI models and improve the effectiveness of cyber defense for all users. These benefits lead to a virtual cycle of increased user engagement and improved cyber security outcomes, making platform-based security solutions an attractive choice for businesses and individuals alike. When conducting a cyber security audit of any IT infrastructure using AI, the limits and depth of the audit are established taking into account previous experience.
Fertilidad edáfica y nutrición en el cultivo de cacao (Theobroma cacao L.) en tres suelos de Tabasco, México
Authors: Francisco-Santiago Sandra Patricia , Palma-López David Jesús , Sánchez-Hernández Rufo , Obrador-Olán José Jesús , García-Alamilla Pedro
Published: June 2023

El cacao es un cultivo tradicional en el sur de México, que exhibe baja productividad debido a limitantes edáficas y de nutrición, por lo que el objetivo de la investigación fue diagnosticar la fertilidad edáfica y contenido nutrimental de las plantaciones de cacao, en los principales grupos de suelos cultivados en la Chontalpa, principal zona productora de Tabasco, para identificar las variables del suelo y nutrimentales que restringen la productividad del cultivo. Mediante análisis de imágenes satelitales, se seleccionaron sitios de muestreos en suelos representativos del área de estudio y se geoposicionaron las coordenadas para ubicarlos. Se describieron perfiles de suelos para clasificar los suelos de los sitios de estudio, y se colectaron muestras de suelos a las profundidades de 0-10, 10-30 y 30-50 cm, para determinar variables indicadoras de la fertilidad del suelo. En árboles productores se colectaron muestras foliares para determinar las concentraciones de macronutrientes. Los resultados indican que las plantaciones se cultivan sobre Vertisols, Cambisols y Fluvisols, que no presentan restricciones en la mayoría de las propiedades edáficas. Sin embargo, debido a la baja relación C/N (< 12) de los suelos, hay una disminución en los contenidos de MO y N, que se suman a un déficit de K, que provocan bajas concentraciones de ambos macronutrientes en el follaje de las plantas. Se concluye que las principales restricciones edáficas que pueden afectar al cultivo del cacao en la Chontalpa son la rápida pérdida de MO y déficit de N y K en el suelo, que provocan bajas concentraciones de ambos nutrientes en el follaje de los árboles.

Authors: Anggara Afwan , Setiafindari Widya
Published: June 2023

Determining the class quota at each period of filling out the KRS (Study Plan Card) at the beginning of the semester is often an activity that cannot be determined easily. This is due to several important factors in it, one of the most influential and difficult things is the uncertainty when determining the quota for the number of students who will take the course in question, if later there is an error in predicting the number of students who will take the course, then the class quota that is prepared will certainly be less so that it leads to the disruption of the ongoing Student KRS registration process. The method used in this study is forecasting using trend analysis which aims to determine how much capacity or inventory is needed for decision-making, then a system will be designed that can be used to predict the number of forecasting quotas for courses that will be provided. The system design applies the system development method with UML. The stages of the process are carried out from collecting and processing subject offer quota data several previous academic years. Research has succeeded in building a model to make predictions using the Trend Analysis method, so that it can be used as a recommendation for the number of quotas offered for the next academic year.

Forgotten collections. Natural History materials preserved in little-known centers
Authors: González Bueno Antonio
Published: June 2023

The most common collection identification tools fix staffing, infrastructure, and size rations to establish which institutions appear on their listing. From this characteristic derives the existence of a set of materials, some of exceptional value, absent in the usual onsultation indexes, due to the fact that the institution does not meet the necessary requirements. We present a global vision of the ‘forgotten collections’ conserved in non-university educational centers, local museums and other spaces located in Spanish territory that conserved materials of Natural History. All of them are funds of special interest to know both, the scientific activity of their authors, as well as to testify their research work. Las herramientas más habituales de identificación de colecciones establecen requisitos de dotación de personal, infraestructura y tamaño para establecer qué instituciones aparecen en sus listados; de esta característica se deriva la existencia de un conjunto de materiales, algunos de excepcional valor, ausentes en los índices de consulta habitual, en razón de que la institución no cumple con los requisitos exigidos. Presentamos una visión global de las ‘colecciones olvidadas’ conservadas en centros docentes no universitarios, museos locales y otros espacios ubicados en territorio español que custodian ejemplares de Historia Natural. Todas ellas albergan fondos de especial interés para conocer tanto la actividad científica de sus autores, como para testificar su tarea investigadora.

Origins and circulation of prehistoric collections in Madrid museums
Authors: Pelayo Francisco
Published: June 2023

The National Museum of Natural Sciences was the first scientific institution in Madrid that guarded a collection of prehistoric objects. The donation was sent in 1847 by a Spanish diplomat appointed in Copenhagen. Twenty years later this collection would be transferred to the National Archaeological Museum, created in 1867. This was the beginning of the circulation of prehistoric collections among the museums of Madrid. The purchase by the State of private collections of prehistoric objects, collected by amateurs, increased the specimens of the two great national museums, that of Natural Sciences and that of Archeology. These two state museums exchanged collections, passing the copies of anthropology, paleontology and geology to the Natural Sciences Museum, and the stone tools to the Archeology Museum. The transfer of collections between museums was extended after the creation of the Anthropology Museum in 1910 and the Prehistoric Museum of the Madrid City Council in 1929. After the Civil War, the prehistory collections of the Anthropology Museum were transferred to the Archaeological Museum. El Museo Nacional de Ciencias Naturales fue la primera institución científica de Madrid que custodió una colección de objetos prehistóricos. La donación fue enviada en 1847 por un diplomático español destinado en Copenhague. Veinte años después esta colección se transfirió al Museo Arqueológico Nacional, creado en 1867. Este fue el comienzo de la circulación de colecciones de prehistoria entre los museos de Madrid. La compra por el Estado de colecciones privadas de objetos prehistóricos, recogidas por aficionados, incrementaron los fondos de los dos grandes museos nacionales, el de Ciencias Naturales y el de Arqueología. Estos dos museos estatales intercambiaron colecciones, pasando al de Ciencias Naturales los ejemplares de antropología, paleontología y geología, y al Arqueológico los instrumentos líticos. La transferencia de colecciones entre museos se extendió tras la creación del Museo de Antropología en 1910 y del Museo Prehistórico del Ayuntamiento de Madrid en 1929. Tras la Guerra Civil, los fondos de prehistoria del Museo de Antropología se traspasaron al Museo Arqueológico.

Published: June 2023

The synthesis of catalysts based on cobalt, copper and manganese oxides by sol-gel method with combustion was carried out, and their catalytic activity was studied in the reaction of low-temperature oxidation of carbon monoxide to dioxide. Oxides of cobalt, copper and manganese, as well as their double oxides (Co–Mn, Cu–Mn and Co–Cu) were synthesized. X-ray phase analysis showed the formation of manganites and oxides of corresponding metals in the Co–Mn and Cu–Mn systems. It was revealed that in the Co–Cu system only oxides of separate metals are formed. It was found that cobaltmanganese and copper-manganese oxide systems synthesized by sol-gel combustion method exhibit high catalytic activity in the low-temperature (110–140 0C) conversion of carbon monoxide into dioxide. One-step synthesis of Cu–Mn/Al2O3 catalytic system was also carried out by sol-gel method with burning precursors with binder hydrogel (Al2O3), and its high activity in low-temperature conversion of carbon monoxide was revealed. The catalytic systems were investigated by X-ray diffraction, IR spectral methods, BET, SEM. The results obtained show the possibility of obtaining active multicomponent oxide catalysts in low-temperature oxidation of carbon monoxide by technologically simple sol-gel combustion method.
Sуnthesis of terpene–methacrylic acid copolymers and their effect on the stability of inorganic dispersions in the presence of cationic surfactants
Authors: Vorobiev A. D. , Bucha S. V. , Vorobieva E. V. , Krutko N. P. , Lipai Yu. V. , Astakhova M. A.
Published: June 2023

Copolymers of methacrylic acid and natural terpene monomers (α-pinene; β-pinene; ∆3-karene) with the molecular weight of (0.3–0.5)∙104 and a content of carboxyl groups of 14.5–16.3 % were synthesized. For the synthesized copolymers, hydrodynamic radius and the Kuhn segment, which characterizes flexibility of a polymer chain, were determined, as well as the Huggins constant in aqueous and saline solutions, and concentration regions for formation of supramolecular structures. In the presence of a cationic surfactant (benzetonium chloride, Hyamine), depending on the concentration of copolymers in the system, polymer-surfactant complexes were formed in soluble and insoluble forms. It has been shown that the effectiveness of the stabilizing action of soluble complexes with respect to an aqueous dispersion of calcium carbonate increases with an increase in the content of nonpolar groups in the polymer chain. A cationic surfactant (Hyamine) has been proposed as a precipitant in the method for the quantitative determination of carboxyl-containing polymers in aqueous and saline media.
Rheological properties and group chemical composition of oxidized bitumen in the presence of fibrous materials of various structures
Authors: Luksha O. V. , Krut’ko N. P. , Chernetskaya V. M.
Published: June 2023

The rheological properties of oxidized bitumen in the presence of fibrous materials based on cellulose and chrysotile asbestos used as stabilizing additives in the production of crushed stone-mastic asphalt concrete mixtures have been studied. It has been established that the supramolecular structure of fibers characterizing the interaction between macromolecules largely determines the effectiveness of their structuring action for oxidized bitumen. Thus, the introduction of cellulose fiber leads to an increase in the ability of the bitumen colloidal structure to the simultaneous occurrence of elastic and plastic components of deformation. This is due to the uniform distribution of the fiber in the dispersion medium of bitumen due to the penetration of hydrocarbon components of bitumen into the interfibrillary space of cellulose and the rupture of hydrogen bonds between hydroxyl groups. Тhe presence of strong structural bonds between chrysotile-asbestos macromolecules prevents the formation of strong reinforcing mesh in bitumen oils. As a result, the values of the structural and rheological parameters Pk1, Pk2 and Pm of the bitumen/chrysotile-asbestos composition are 1.5–2 times lower compared to the values for the bitumen/cellulose composition. The results of the study of the group composition and structural-rheological properties of bitumen compositions after heating at T = 163 °C indicate a higher stability of the bitumen-cellulose structure to the processes of thermal oxidative degradation compared to the structure formed in the bitumen/chrysotile-asbestos composition. By the method of thin-layer chromatography, it was found that the concentration of oils in the bitumen/chrysotile-asbestos composition is higher as compared to the bitumen/cellulose composition, indicating that the weakening of rheological properties and thermal stability in the presence of chrysotile-asbestos is not related to the microstructure of its fibers, which, according to some researchers, is prone to selective diffusion of oils into the capillaries of fibrils.

The results of a study on the use of glauconite-containing overburden rocks of the Novodvorskoye deposit of the Pinsk district of the Brest region to produce glasses for various purposes are presented. The compositions of raw materials in the system «glauconite-containing rock – chalk – iron oxide – soda ash» have been developed, the limiting amount of the raw components and basic oxides in glasses have been optimized. It has been established that the main criterion for obtaining high-quality glasses is a rational combination of refractory and low-melting oxides, which ensures the homogeneity of glasses, working viscosity, the ability to form in various ways, the absence of a tendency to crystallization, black color in the mass, as well as a complex of satisfactory physical and chemical properties. The results of the study confirmed the prospects of using the glauconite-containing overburden for the synthesis of glasses for various purposes, which will contribute to the rational use of natural resources and associated minerals of the Novodvorskoye deposit of the Republic of Belarus, and will improve the environmental situation in the areas adjacent to the deposit.

The aim of the work was to study the morphological state of the dentition of persons with normal occlusion according to cephalometric X-ray using extraoral parameters.

A method for assessing the state of the maxillofacial system using the PoN reference line, PL line, PLV extrafacial vertical line is proposed. Schemes for determining the parameters formed on their basis are presented as well. These parameters will allow diagnosing disorders of maxillofacial system in patients with malocclusions at a higher quality level.

The average values of the proposed new parameters were determined and presented in tables using extraoral parameters in persons 7–15 years old with normal occlusion. A comparative analysis of the angular and linear indices of cephalometric images in persons 7–12 and 12–15 years old with normal occlusion showed that with age the tendency of their change is identical to traditional methods.

The proposed and studied angular and linear indices of cephalometric images in persons 7–15 years old with normal occlusion using extraoral parameters (PL line and PLV vertical line) are recommended for use in the practical work of orthodontists.

Kuliah Kerja Nyata (KKN) merupakan salah satu bentuk pengabdian kepada masyarakat yang dilakukan perguruan tinggi. Kegiatan KKN dilakukan di Desa Mondu, Kecamatan Kanatang, Kabupaten Sumba Timur. Desa ini selain memiliki potensi, juga terdapat beberapa permasalahan, yakni sejumlah siswa sekolah dasar dan menengah mengalami kesulitan dalam memahami materi pelajaran di sekolah sebagai akibat sekolah dari rumah yang terjadi pada saat pandemi Covid-19,  beberapa UMKM khususnya usaha tenun ikat yang pemasaran produknya hanya melalui penjualan di pasar tradisional dan menunggu pembeli datang membeli produknya sehingga omzet penjualan kecil dan terdampak juga dari pandemi Covid-19, dan beberapa objek wisata yang ada di Desa mondu belum semuanya diketahui oleh masyarakat luas. Oleh karena itu, program KKN yang dilakukan adalah bimbingan belajar bagi siswa, pengenalan media sosial bagi pengrajin tenun ikat, dan membuat video objek wisata di Desa Mondu. Tujuan dari kegiatan KKN ini adalah untuk menjawab ketiga permasalahan yang telah disebutkan. Metode kegiatan yang digunakan adalah metode ceramah, tanya jawab, dan latihan  (bimbingan belajar), metode sosialisasi dan praktik (pengenalan media sosial), serta  perancangan konsep dan perekaman gambar (pembuatan video objek wisata).  Hasil yang dicapai adalah beberapa siswa mampu menguasai materi pembelajaran yang diberikan, terdapat empat akun media sosial yang dibuat untuk kelompok pengrajin tenun ikat, dan video objek wisata yang telah dibuat dan disebarkan.  Dapat disimpulkan bahwa pelaksanaan Kuliah Kerja Nyata (KKN) yang telah dirancang dapat berjalan sesuai dengan yang telah direncanakan dan kegiatan ini juga mampu menjawab beberapa permasalahan terkait pendidikan, pemasaran produk, dan pariwisata.
