Investigation of Interaction Mechanisms of High Energy Electrons and Gamma Quantum with Aqueous Solution of Methyl Orange Dye

The level of development of modern nuclear technologies forms a request for the development of new branches of science. At the same time, chemical dosimetry methods are also being improved [1, 2]. The essence of such methods consists in the quantitative determination of the radiation-chemical damages to the molecules of a substance when it is exposed to ionizing radiation [3, 4]. Liquid and solid solutions of organic dyes have intense bands optical absorption and fluorescence in the visible region of the spectrum, which makes it possible to use them in dosimetry systems [5, 6]. The use of organic dyes makes it possible to determine the absorbed dose in the range from 10-6 to 104 M Rad [7, 8]. In this work, we studied the processes of interaction of gamma-ray and high-energy electron fluxes with an aqueous solution of the organic dye methyl orange (C14H14N3О3SNa) [9, 10]. The calculations and experiment were carried out on a resonant electron accelerator with energies up to 30 MeV. The electron beam energy was 15 MeV. A tungsten converter was used to generate gamma quanta. The thickness of the converter varied from 0 to 6 mm. We have developed a computer program in C++ to simulate the irradiation process. This program uses the Geant4 class library based on the Monte Carlo method and runs in multi-threaded mode. For calculations, the model “PhysicsList emstandard_opt3” was chosen as the most suitable one. The value of radiation damage per one incident electron and produced gamma-quantum is determined in the work. The simulation results are compared with experimental data. Based on the results obtained, conclusions were drawn about the main mechanisms leading to the decomposition of organic dye molecules, and methods for optimizing the experiment for further research were proposed.

Categorization optimization in the construction of thematic products

ABSTRACT One of the steps in the construction of thematic products is the categorization. This process is done by partitioning the range of values of a given feature into several subranges and associating a new value, in this case ordinal, to all instances that are in that subrange. The objective of this work is to propose an innovative pre-categorization process that applies a computational search method to maximize the accuracy of thematic products during the classification stage. The theme feature used is the Above Ground Biomass (AGB), which estimation model is built over synthetic aperture radar features. A system is developed in Java script using the Weka data mining class library. The proposed heuristic is the hill climbing greedy, with the Kappa coefficient as the objective function. The results obtained shows that the proposed Categorization Optimization algorithm demonstrated the ability to obtain new states with subintervals of categories that increased the Kappa agreement index to 1.0 with much lower computational cost than the exhaustive search. The thematic products constructed maintained the representativeness of the study area while increasing in thematic accuracy.

Visual Simulation of Modern Supply Chain Based on MR Virtual Reality Technology

In order to improve the management and operation efficiency of the modern supply chain, this paper combines the MR virtual reality technology to carry out the visual simulation of the modern supply chain. Moreover, this paper uses MR virtual simulation technology to perform intelligent perception of supply chain transportation equipment and transportation objects, recognize its shape and the force it receives, and ensure that there is no damage during the transportation process. The visual simulation of supply chain is realized by real-time dynamic display based on geometric model. Moreover, this paper combines the MR virtual reality technology to define the geometric and kinematic characteristics of the modeled object, then encapsulates these characteristics into the object class, and defines the behavior characteristics to establish an object class library. Finally, the experimental research verifies that the modern supply chain visual simulation technology based on MR virtual reality technology has a good simulation effect in the supply chain system.

A software package for solving grid equations in areas with geometry "stretched" along one of the spatial directions

A method for solving grid equations in areas with geometry "stretched" along one of the spatial directions is proposed. Method proposed for model includes pollutants whose concentration in the Azov Sea, according to the analysis of scientific publications and environmental databases, exceeds the maximum permissible concentration (MPC). The mechanism of the preconditioner formation is described. The estimation of the minimum and maximum eigenvalues is performed. Using object-oriented analysis and design, a class library has been implemented to solve the problem of impurity propagation in a shallow reservoir. The architecture of an information system to support scientific research capable of functioning in conditions of using heterogeneous computing environments is described. The system is based on the requirement of the maximum possible use of free software in order to minimize capital and operational costs. The system uses classes that allow you to read and write information about the geometry of the object under study and the parameters of the calculated grid. Numerical experiments were carried out using the developed software package, including the proposed mathematical model, focused on the multiprocessor computing system (MCS). The dependences of the SLAE solution time on the number of diagonals and the order of the matrix are obtained. The number of iterations for solving grid equations has been experimentally determined depending on the ratio of the number of nodes in spatial coordinates.

Processing the overlay of geometry segments in solving hydrophysics problems by the finite difference method

The article deals with issues related to increasing the efficiency of working with data on the geometry of the computational domain when solving hydrophysics problems using the finite difference method. The model problem is a system of equations of the pollutant distribution, including the oil and its refined products, in the computational domain – Azov Sea. To describe the computational domain, a model of a two-dimensional computational grid is used, which is used in the implementation of numerical calculations. Class diagrams are presented for describing the geometry of the object under study, as well as its constituent segments. In order to improve the performance of calculations, an algorithm for combining geometry segments was developed, in which the original algorithm was divided into separate fragments by introducing a number of conditional structures. As a result of experimental data processing, regression equations were obtained that describe the dependence of the algorithm execution time on the number of joins. The developed algorithm and class library make it possible to work with the description of the geometry of the object under study as a set of parameterized primitives and educe the time spent on the formation of the description of the computational domain by up to 27%.

ПОИСК ТЕОРЕТИЧЕСКИХ ОСНОВ ПРОЕКТИРОВАНИЯ ДЕТСКИХ МЕДИАТЕК

The article deals with the issue of the prospective development of a new type of buildings - children's media libraries, which are a structural unit of a typological group of public buildings. This type of building has emerged from the globalized leisure needs of children of different age groups. Against the background of the post-stagnation development of the library network, through the implementation of various state programs, the principles of continuity of the classical library function are implemented and media technologies are included in leisure activities. At the junction of the confluence of these two areas, there is the emergence of children's media libraries, whose development is actively carried out in foreign countries and begins to emerge on the territory of the Russian Federation. The study below is devoted to the search for the theoretical foundations of the architectural design of this type of building. Without constructing a theoretical vector for the development of a functionally adaptive scenario, the architectural typology of children's media libraries will not have a thorough study in terms of functional, spatial and technological development. The article is divided into three blocks: an analytical comparison of the most characteristic examples of modern design of media libraries, a retrospective analysis of regulatory documents governing construction, which made it possible to systematize the development of libraries by types of buildings, and then a theoretical model of media libraries based on advanced architectural and pedagogical technologies is proposed.

Web Search Training and Query Formulation Behaviour of Undergraduates of Kano State University of Science and Technology (KUST) Wudil, Kano State, Nigeria

The Web is predominant source of information upon which most university students depend for accomplishing their academic tasks. This study investigated the influence of web search training program on query formulation behaviour of undergraduates of Kano State University of Science and Technology (KUST), Wudil, Kano State, Nigeria. The study was set to answer two research questions and tested a hypothesis. Quasi-experimental design of the pretest and posttest type was used for the study. All 20,679 undergraduates of KUST made up the target population. Convenience sampling technique was used to recruit only 35 students, who participated in a six-week training program and lab sessions. A structured and validated questionnaire was used for data collection at both pretest and posttest levels. Cronbach’s alpha reliability coefficient for the constructs ranged 0.78 to 0.88. Two adapted search task tests were used to assess students’ query formulation behaviour on the web before and after the training. Data were analyzed with descriptive statistics and t-test. Findings revealed that web search training had significant effect on the query formulation behaviour of participants (t(34) = 17.680; p <0.05,η2= 0.857). The study concluded that web search training is essential for all undergraduate students of KUST Wudil to enable them to develop appropriate web search query formulation behaviour and also accomplish their academic search tasks. The study recommended that academic librarians should include practical web search sessions in their use of library classes for freshmen.

Lessons learned from teaching: Reinventing the librarian in credit-bearing courses

Delaware Valley University is a private university located about one hour north of Philadelphia in bucolic Bucks County. The librarians at its Krauskopf Memorial Library have faculty status, which allows us to serve on faculty committees and teach credit-bearing courses. Despite this, librarians have only taught the first-year experience course, which is otherwise taught primarily by staff. This course is heavily scripted and not owned by the faculty, unlike other courses. It does not offer opportunity for course development or for building relationships with teaching faculty, both of which are important for instruction librarians. Most of our instruction librarians only have experience teaching one-shot information literacy sessions and are rarely embedded into a course. Much of the literature on semester-long library classes focuses on information literacy skills. These courses are designed by librarians as an antidote to the one-shot. But what if the information literacy was incorporated into course development? Could students learn research skills in a way that supported the ACRL Framework for Information Literacy for Higher Education and inspired students’ interests?

Phase-Controlled Synthesis and Quasi-Static Dielectric Resonances in Silver Iron Sulfide (AgFeS2 ) Nanocrystals.

Ternary metal-chalcogenide semiconductor nanocrystals are an attractive class of materials due to their tunable optoelectronic properties that result from a wide range of compositional flexibility and structural diversity. Here, the phase-controlled synthesis of colloidal silver iron sulfide (AgFeS2 ) nanocrystals is reported and their resonant light-matter interactions are investigated. The product composition can be shifted selectively from tetragonal to orthorhombic by simply adjusting the coordinating ligand concentration, while keeping the other reaction parameters unchanged. The results show that excess ligands impact precursor reactivity, and consequently the nanocrystal growth rate, thus deterministically dictating the resulting crystal structure. Moreover, it is demonstrated that the strong ultraviolet-visible extinction peak exhibited by AgFeS2 nanocrystals is a consequence of a quasi-static dielectric resonance (DR), analogous to the optical response observed in CuFeS2 nanocrystals. Spectroscopic studies and computational calculations confirm that a negative permittivity at ultraviolet/visible frequencies arises due to the electronic structure of these intermediate-band (IB) semiconductor nanocrystals, resulting in a DR consisting of resonant valence-band-to-intermediate-band excitations, as opposed to the well-known localized surface plasmon resonance response typically observed in metallic nanostructures. Overall, these results expand the current library of an underexplored class of IB semiconductors with unique optical properties, and also enrich the understanding of DRs in ternary metal-iron-sulfide nanomaterials.

Literatura i promoció social: lectura i creació literàries entre els menestrals catalans medievals

This article aims to prove the active role played by artisans as consumers (readers, owners, copyists) of literature besides elite and court circles, and links it to the strategies of social promotion launched by that dynamic social group. The analysis is based on two types of sources: on the one hand, on an extensive sample of the presence of literary works in the libraries of the medieval Catalan lower middle classes, derived from the main documentary collections on history of the books produced to date; and, on the other hand, on some literary codices copied by individuals belonging to that social sphere, which have been re-examined. In addition, some individuals are identified regarding the transmission of some works of Francesc Eiximenis ( Llibre de les dones and Llibre dels àngels ) and the Catalan translation of La Queste del saint Graal , as well as regarding the origin of Jaume Conesa’s translation of Guido delle Colonne’s Historia destructionis Troie .

Technical Report: Development and Implementation of an Open Source Template Interpretation Class Library for Automated Treatment Planning

PurposeWidespread implementation of automated treatment planning in radiation therapy remains elusive owing to variability in clinic and physician preferences, making it difficult to ensure consistent plan parameters. We have developed an open-source class library with the aim to improve efficiency and consistency for automated treatment planning in radiation therapy. Methods and MaterialsAn open-source class library has been developed that interprets clinical templates within a commercial treatment planning system into a treatment plan for automated planning. This code was leveraged for the automated planning of 39 patients and retrospectively compared with the 78 clinically approved manual plans. ResultsFrom the initial 39 patients, 74 of 78 plans were successfully generated without manual intervention. The target dose was more homogeneous for automated plans, with an average homogeneity index of 3.30 for manual plans versus 3.11 for automated plans (P = .107). The generalized equivalent uniform dose (gEUD) was decreased in the femurs and rectum for automated plans, with a mean gEUD of 3746 cGy versus 3338 cGy (P ≤ 0.001) and 5761 cGy versus 5634 cGy (P ≤ 0.001) for the femurs and rectum, respectively. Dose metrics for the bladder and rectum (V6500 cGy and V4000 cGy) showed recognizable but insignificant improvements. All automated plans delivered for quality assurance passed a gamma analysis (>95%), with an average composite pass rate of 99.3% for pelvis plans and 98.8% for prostate plans. Deliverability parameters such as total monitor units and aperture complexity indicated deliverable plans. ConclusionsProstate cancer and pelvic node radiation therapy can be automated using volumetric modulated arc therapy planning and clinical templates based on a standardized clinical workflow. The class library developed in this study conveniently interfaced between the plan template and the treatment planning system to automatically generate high-quality plans on customizable templates.

Network mechatronic positioning system of plasma spraying unit

The work is devoted to the implementation of the architecture of embedded computing systems in a high-speed complex for diagnostics of thermal spraying of coatings. On the basis of the Arduino Yun R.2 microcontroller, a software and hardware interface for controlling the positioning system equipment has been developed, and a message exchange protocol in a network environment for interacting with other subsystems of the measuring complex. The computing means of the system have implemented a protocol for synchronizing the internal clock with the neighbors of the measuring complex with an accuracy of 1 ms. Remote control of the positioning system is based on a remote control with an IR communication channel and an LCD screen. An alternative interface for interactive control of the system by the user is deployed on a microcontroller using a Web server. Also, the computing resources of the Atheros processor on the Arduino Yun provide the operation of a client-server application that uses a database to store information about tasks for moving the carriage and its movement tracks. The positioning system site supports the development of client applications in C++, C #, Python, Matlab using the source code of the class of control objects, reference materials and dynamic link libraries.

A Range and Performance Optimized Version of the Computer-Aided Speckle Interferometry Algorithm for Real-Time Displacement-Strain Field Monitoring

This work presents an optimized implementation of the Computer-Aided Speckle Interferometry algorithm which enables full-field determination of displacements and strains on commodity Graphics Processing Units at high resolution and frame rates. By combining careful control of the average speckle size in a laser speckle pattern with a simple sampling rate conversion scheme, a compact representation of the optical speckle is achieved. This allows for optimal use of Graphics Processing Unit architecture with robust range extension. The optimal mapping of the Computer-Aided Speckle Interferometry algorithm to Graphics Processing Unit architecture is shown in detail, and a straightforward method for disambiguating large displacements is illustrated. Lastly, this paper demonstrates a two-step subimage-tapering modification to the original algorithm that enables robust range enhancement while maintaining resolution. Results from numerical simulations on synthetic speckle patterns are shown, and runtime performance metrics are provided, with performance ranging up to 60 frames per second in some cases. The method is suitable for interactive experimental mechanics research, process and testing or any application where real-time high-resolution displacement-strain monitoring is needed. A .NET Framework class library enabling the incorporation of the algorithm into 3rd -party applications is available for download.

Virtual Screening of the Flavonoids Compounds with the SARS-CoV-2 3C-like Protease as the Lead Compounds for the COVID-19

As of 1st of September 2020, the COVID-19 pandemic has reached an unprecedented level of more than 25 million cases with more than 850,000 deaths. Moreover, all the drug candidates are still undergoing testing in clinical trials. In this regard, a breakthrough in drug design is necessary. One strategy to devise lead compounds is leveraging natural products as a lead source. Several companies and research institutes are currently developing anti-SARS-CoV-2 lead from natural products. Flavonoids are well known as a class of antiviral compounds library. The objective of this research is to employ virtual screening methods for obtaining the best lead compounds from the library of flavonoid compounds. This research employed virtual screening methods that comprised of downloading the protein and lead compound structures, QSAR analysis prediction, iterations of molecular docking simulation, and ADME-TOX simulation for toxicity prediction. The QSAR analysis found that the tested compounds have broad-spectrum antiviral activity, and some of them exhibit specific binding to the 3C-like Protease of the Coronavirus. Moreover, juglanin was found as the compound with the fittest binding with the Protease enzyme of SARS-CoV-2. Although most of the tested compounds are deemed toxic by the ADME-Tox test, further research should be conducted to comprehend the most feasible strategy to deliver the drug to the infected lung cells. The juglanin compound is selected as the fittest candidate as the SARS-CoV-2 lead compound in the tested flavonoid samples. However, further research should be conducted to observe the lead delivery method to the cell.

Jesuits, Transylvanian Baroque and the Middle Ages: Ignatius Batthyány and Saint Gerardus of Cenad

Although considered as the end of the Late (baroque) Scholasticism, in Central Europe the 18th century still bore the substance of philosophical thinking and education of the Jesuit baroque philosophy, especially its ideal of building study societies and classical libraries accompanied by astronomical observatories and scientific collections. The Jesuit model of Eger was brought by the Transylvanian Bishop Ignatius Batthyány at Alba Iulia where he has established a learning place consisting in a classical and theological library and founded a literary society, trained a professional librarian and aimed at offering a study place for meritory scholars. He was himself a theologian, paleographer and historian, edited and commented on the treatise Deliberatio supra hymnum trium puerorum ad Isingrimum liberalem by the 11th century Benedictine Bishop Gerardus of Cenad. Bishop Batthyány was for many reasons a baroque scholar although many times introduced as a man of Enlightenment by some historians.
