Ochrona życia dzieci nienarodzonych w nauczaniu Kościołów katolickiego i luterańskiego
Authors: Filipiuk Łukasz
Published: March 2024

Artykuł dotyczy problematyki obrony życia nienarodzonych w nauczaniu Kościołów katolickiego i luterańskiego. Niniejsza refleksja została podjęta w związków z przypadającą w 2023 roku 30. rocznicą wprowadzenia w Polsce Ustawy o planowaniu rodziny, ochronie płodu ludzkiego i warunkach dopuszczalności przerywania ciąży. Kościół katolicki i Kościół ewangelicko-augsburski na różny sposób wyrażają troskę o los dzieci poczętych zagrożonych aborcją. Każdy z nich podejmuje wysiłek teologiczny tak dla uzasadnienia, jak również dla obrony wartości i godności życia ludzkiego. Chodzi jednak o to, by w ramach dialogu ekumenicznego podjąć wspólne działania promujące cywilizację życia. Ze wszystkich inicjatyw, modlitwa powinna być na pierwszym miejscu. Następnie z niej mogą wynikać inne, pożądane działania. Istotny jest duszpasterski przekaz treści, które trafiają do wiernych obu Kościołów. Mają one prowadzić do akceptacji tego, co służy życiu, i odrzucenia wszelkich form zakłamania prawdy o godności ludzkiej osoby, o wartości życia, o poszanowaniu prawa do życia. Tego rodzaju wysiłek już został podjęty, ale wciąż wydaje się być niewystarczający w obliczu ataków na życie dzieci nienarodzonych ze strony środowisk proaborcyjnych.
Orthodoxy and interreligious dialogue
Authors: Boldisor Adrian
Published: March 2024

The interreligious dialogue has a very important place in all the meeting agendas from all over the world, regardless the topic addressed. Having a concrete dynamic, this kind of theological problematic follows the general spiritual movement of communities and their unresolved necessities. Although the interreligious dialogue has an old history, it developed today on the basis of actual issues of violence and disagreements between peoples. Therefore, because religion has an essential place in the life of human communities from all over the world, the dialogue with people of other faiths and ideologies must be necessarily promoted. In this context, the Orthodox Church representatives participated at many meetings in the purpose to promote and sustain the interreligious dialogue, bringing in actuality their bi-millenaries theological experience, based on the Holy Scripture and Holy Tradition. From the orthodox point of view, the liberty is the greatest gift which God has give to man and also a free world cannot exist without love between people. This love has its fundament and purpose in the Holy Trinity.

Ekumenia na rozdrożu – ku jedności czy wspólnocie?
Authors: Porada Rajmund
Published: March 2024

W artykule podjęto problem uwarunkowań osłabienia ekumenicznego impetu, który można było zaobserwować w drugiej połowie XX w. i który doprowadził do postawienia na nowo kluczowego pytania o cel ekumenicznej drogi. Mimo złożoności i wielości problemów dzielących Kościoły uznano, że głównym powodem stagnacji są różnice w rozumieniu Kościoła. Swoistego rodzaju cezurą znaczącą rozejście się celów ekumenicznej drogi, zwłaszcza w relacjach katolicko-protestanckich, na których zasadniczo skoncentrowano uwagę, była deklaracja Dominus Iesus. Odtąd pojawiają się po protestanckiej stronie wypowiedzi wyraźnie dystansujące się od koncepcji widzialnej jedności i preferujące niejako alternatywny model wspólnoty Kościołów. W odpowiedzi na te głosy sformułowano argumenty za pozornym charakterem tak stawianej alternatywy. Urzeczywistnianie widzialnej jedności Kościoła może bowiem dokonać się wyłącznie „przez” i „we” wspólnocie różnych Kościołów, ponieważ sam Kościół jest zgromadzeniem (wspólnotą) wszystkich ludów i narodów w jednym ludzie Bożym.
The modiҥcation of algorithms for the estimation of the fractal dimension for cloud’s images
Authors: Калайда В.Т. , Шапошников А.И.
Published: March 2024

Статья посвящена разработке методики оценки фрактальной размерности облачных образований. Изображения облачного покрова Земли содержат наложенные и частично перекрывающие друг друга различные типы облачности. Каждый тип облачности обладает различными значениями коэффициентов ослабления излучения, поэтому задача разделения типов облачности является важнейшей при вычислении радиационного баланса. Значимый информативный параметр при классификации облачности — фрактальная размерность. Вместе с тем получаемые при использовании ҡсовременныхә методов и алгоритмов оценки фрактальной размерности существенным образом зависят от ҡпозиционированияә объекта. В работе предложена эффективная (по точности), инвариантная относительно ҡпозиционированияә объекта, методика оценки фрактальной размерности.

The research addresses the development of methodology for estimating the fractal dimension of cloud formations. Images of the Earth’s cloud cover contain superimposed and partially overlapped different types of cloud cover. Taking into account that each type of cloudiness has different values of coefficients for radiation attenuation, the problem of separating cloud types is the most important when assessing the radiation balance. The most important feature used in the classiҥcation of cloudiness is the fractal dimension. At the same time, the estimates obtained by using ҡmodernә methods and algorithms for estimating the fractal dimension signiҥcantly depend on the ҡpositioningә of the object. The paper proposes an effective (in terms of accuracy) method for estimating the fractal dimension, which is invariant with respect to the ҡpositioningә of an object.

Quantum mechanics/molecular mechanics (QM/MM) simulations offer an efficient way to model reactions occurring in complex environments. This study introduces a specialized set of charge and Lennard-Jones parameters tailored for electrostatically embedded QM/MM calculations, aiming to accurately model both adsorption processes and catalytic reactions in zirconium-based metal-organic frameworks (Zr-MOFs). To validate our approach, we compare adsorption energies derived from QM/MM simulations against experimental results and Monte Carlo simulation outcomes. The developed parameters showcase the ability of QM/MM simulations to represent long-range electrostatic and van der Waals interactions faithfully. This capability is evidenced by the prediction of adsorption energies with a low root mean square error of 1.1 kcal/mol across a wide range of adsorbates. The practical applicability of our QM/MM model is further illustrated through the study of glucose isomerization and epimerization reactions catalyzed by two structurally distinct Zr-MOF catalysts, UiO-66 and MOF-808. Our QM/MM calculations closely align with experimental activation energies. Importantly, the parameter set introduced here is shown to be compatible with the widely used universal force field (UFF). Moreover, we thoroughly explore how the size of the cluster model and the choice of density functional theory (DFT) methodologies influence the simulation outcomes. This work provides an accurate and computationally efficient framework for modeling complex catalytic reactions within Zr-MOFs, contributing valuable insights into their mechanistic behaviors and facilitating further advancements in this dynamic area of research.

Authors: Biswas Sohag , Wang Xian , Wong Bryan
Published: March 2024

The elimination of per- and polyfluoroalkyl substances (PFAS) in water continues to garner significant attention due to their enduring presence in the environment and associated health concerns. The emergence of advanced reduction processes (ARPs) holds significant promise in reducing persistent PFAS in water, primarily due to its ability to produce short-lived yet highly reductive hydrated electrons. This concise review offers insights into the latest developments in ARP-based PFAS degradation, encompassing both experimental and theoretical investigations conducted within the last 2 - 5 years. We conclude with an outlook on potential research avenues in this dynamic field and suggest future experimental and computational strategies to enhance ARP capabilities.

Building reliable and robust quantitative structure-property relationship (QSPR) models is a challenging task. First, the experimental data needs to be obtained, analyzed and curated. Second, the number of available methods is continuously growing and evaluating different algorithms and methodologies can be arduous. Finally, the last hurdle that researchers face is to ensure the reproducibility of their models and facilitate their transferability into practice. In this work, we introduce QSPRpred, a toolkit for analysis of bioactivity data sets and QSPR modelling, which attempts to address the aforementioned challenges. QSPRpred's modular Python API enables users to intuitively describe different parts of a modelling workflow using a plethora of pre-implemented components, but also integrate customized implementations in a "plug-and-play" manner. QSPRpred data sets and models are directly serializable, which means they can be readily reproduced and put into operation after training as the models are saved with all required data pre-processing steps to make predictions on new compounds directly from SMILES strings. The general-purpose character of QSPRpred is also demonstrated by inclusion of support for multi-task and proteochemometric modelling. The package is extensively documented and comes with a large collection of tutorials to help new users. In this paper, we describe all of QSPRpred's functionalities and also conduct a small benchmarking case study to illustrate how different components can be leveraged to compare a diverse set of models. QSPRpred is fully open-source and available at https://github.com/CDDLeiden/QSPRpred. Scientific Contribution QSPRpred aims to provide a complex, but comprehensive Python API to conduct all tasks encountered in QSPR modelling from data preparation and analysis to model creation and model deployment. In contrast to similar packages, QSPRpred offers a wider and more exhaustive range of capabilities and integrations with many popular packages that also go beyond QSPR modelling. A significant contribution of QSPRpred is also in its automated and highly standardized serialization scheme, which significantly improves reproducibility and transferability of models.
An Automated Dual Modeling Approach to Accelerate Reaction Analysis and Optimization
Authors: Sagmeister Peter , Melnizky Lukas , Williams Jason , Kappe C. Oliver
Published: March 2024

In modern pharmaceutical research, the demand for expeditious development of synthetic routes to active pharmaceutical ingredients (APIs) has led to a paradigm shift towards data-rich process development. Conventional methodologies en-compass prolonged timelines for reaction and analytical model developments. Both method developments are separated into different departments and often require an iterative process to optimize the models. Addressing this issue, we intro-duce an innovative dual modeling approach, seamlessly integrating the development of a Process Analytical Technology (PAT) strategy with reaction optimization. This integrated approach is exemplified in diverse amidation reactions and the synthesis of the API benznidazole. The platform, characterized by a high degree of automation and minimal operator in-volvement, achieves PAT calibration through a “standard addition” approach. Dynamic experiments are executed to screen a broad process space and gather data for fitting kinetic parameters. Employing a Julia-coded software program facilitates rapid kinetic parameter fitting and in-situ optimization within minutes. This highly automated workflow not only expedites the understanding and optimization of chemical processes, but also holds significant promise for time and resource savings within the pharmaceutical industry.

The structural dynamics involved in the mechanical flexibility of molecular crystals are not well understood yet. Here, we report an elastically bending lipidated molecular crystal that shows systematic shifts in characteristic vibrational frequencies across the bent crystal region - revealing the nature of structural changes during bending and the local internal stress distribution. The elastic flexibility is rendered by intermolecular N-H∙∙∙O hydrogen-bonded chains along with strong yet flexible alkyl-chain hydrophobic interactions in this crystal structure. The blue shifts in the bond stretching modes (such as C=O and C-H modes) in the inner arc region and red shifts in the outer arc region of the bent crystals observed via micro-Raman mapping are counterintuitive to the bending models based on intermolecular hydrogen bonds. Correlating these shifts with the trends observed from high-pressure Raman studies on the crystal reveals the local stress difference between the inner arc and outer arc regions of the bent crystal to be ~2 GPa, more than an order of magnitude higher than the previously proposed value in elastically bending crystals. High local internal stress can have direct ramifications on the properties of molecular piezoelectric energy harvesters, actuators, semiconductors, and flexible optoelectronic materials.

Authors: Shakoor Aamir , Mangi Sajjad Ali
Published: March 2024

This study focuses on the utilization of Rice Husk Ash (RHA) as partial replacement of Ordinary Portland Cement (OPC) in concrete in addition with Polypropylene (PP) fiber. The main goal of this study was to decrease dependence on OPC and address environmental waste generated through rice mills. This study considered concrete cubes prepared through 1:2:4 ration with 0.50 water-cement ratio with and without RHA and PP fibers. The water curing was done for 7 and 28 days, with three specimens for each proportion, and the average value was considered as the result. It was observed that the compressive strength of M2 concrete which containing 10% RHA was noticed 7% higher than the control mix concrete and declared as 10% RHA as optimum dosage. Next, the performance in terms of compressive strength of concrete containing optimum dosage of RHA in presence of PP fibers of three different lengths were also evaluated and found that the 0.1% of PP fiber of 0.5 inches length gives the 25% higher strength performance as compared to the control mix and 17% higher than the concrete containing 10% RHA only at the age of 28days. Hence, this study concluded that the replacing OPC cement with 10% RHA produces satisfactory strength performance and incorporation of PP fiber gives better strength performances.

Many studies indicate the incidence of bronchial tuberculosis from 10% to 40%, taking into account the level of diagnostic measures to detect tuberculosis and the availability of endoscopic services. An important problem in the treatment of tuberculosis is psychological problems in patients, including those with drug-resistant tuberculosis. In phthisiology, attention is drawn to the widespread history of stress in patients with tuberculosis and the complexity of psychological rehabilitation against the background of treatment. In relation to such patients, it is advisable to use a comprehensive medical and psychological approach, including specialized care based on the developed models of psychological rehabilitation. A large number of studies show that among patients with tuberculosis of the trachea and bronchi, young women, non-smokers with a high level of education and income are about 2 times more likely. An important problem is also unstable compliance and low stress tolerance in patients with neurotic personality organization, prone to actualization of maladaptive stereotypes of responding to the difficulties of the treatment process. This clinical example demonstrates the high efficiency of complex treatment of the tuberculosis process, which included anti-tuberculosis therapy, inhalation therapy, surgical treatment and psychological correction. Despite the late diagnosis of the tuberculosis process, relief of intoxication syndrome, cessation of bacte excretion and improvement of the clinical condition were achieved by 2 months of treatment. This approach in the complex treatment of the tuberculosis process is extremely important and relevant to achieve high treatment results.

INTERNATIONAL TRADE IN AGRI-FOOD PRODUCTS IN THE CONTEXT OF REGIONAL PECULIARITIES AND INTERNATIONAL ECONOMIC INTEGRATION
Authors: Kryvenko Nadiia
Published: March 2024

This paper examines world trade in agri-food products in the context of international economic integration. This is due to the importance of foreign trade for the economic development of countries, especially in the context of globalisation, the increase in the number of integration groups whose participation affects the terms of trade of their member and non-member countries, and the aggravation of the food crisis. The purpose of this article is to identify the state and trends of world trade in agri-food products, taking into account regional characteristics and the participation of countries in integration groupings, and to determine their role in the future. Methodology. The research is based on a comparison of parts of individual regions and integration groups in world trade, identifying trends and features. The publication uses the methods of analysis, synthesis, generalisation, comparative assessment, and graphical methods, in particular, to identify the main trends, draw conclusions, etc. Results. The study shows that world trade in agri-food products is growing significantly, both globally and by region. The countries of Europe and the Americas are the main exporters, but the countries of Asia, South and Central America and Africa are the fastest growing exporters. However, the main suppliers remain the member countries of the most advanced integration groupings - the European Union, the North American Free Trade Agreement (NAFTA) and the Southern Common Market (MERCOSUR). It is proposed to divide the main exporters into regions, integration groups and countries. The issue of food security is one of the most important in modern conditions and within the integration groups. It is advisable that they contribute to some extent to solving this problem at the regional level and in relation to third countries. To this end, it is advisable to develop measures to provide food aid to countries affected by natural disasters, climate change or other adverse circumstances on several fronts: within integration groups, in the region and at the global level. These groups are expected to remain among the largest suppliers of agri-food products in the future, and one of the main reasons for this is their participation in integration groups, which facilitates the liberalisation of the movement of new technologies, in particular to the agricultural sector.

En este artículo examinamos los matrimonios de carácter diplomático realizados por las casas reales fenicias con otros estados del Mediterráneo oriental a lo largo del I milenio a. C., así como entre los miembros de sus propias aristocracias, incluyendo también las radicadas en sus colonias, particularmente Cartago. Al mismo tiempo contemplamos sus antecedentes en la Edad del Bronce, lo que nos permite comprobar que se trataba de una costumbre que estaba muy arraigada en su pasado. Su existencia los convierte en un instrumento más de la política exterior de estas ciudades estado, en plena concordancia con lo que hicieron también otras monarquías y aristocracias de su época.

Gibraltar subduction zone is invading the Atlantic

Subduction initiation is a cornerstone of the Wilson cycle. It marks the turning point in an ocean’s lifetime, allowing its lithosphere to be recycled into the mantle. However, formation of subduction zones in Atlantic-type oceans is challenging, given it commonly involves the action of an external force, such as the slab pull from a nearby subduction zone, a far-field compression or the impact of a plume. Notwithstanding, the Atlantic already has two subduction zones, the Lesser Antilles and the Scotia arcs. These subduction zones have been forced from the nearby Pacific subduction zones. The Gibraltar Arc is another place where a subduction zone is invading the Atlantic. This corresponds to a direct migration of a subduction zone that developed in the closing Mediterranean basin. Nevertheless, few authors consider the Gibraltar subduction still active because it has significantly slowed down in the last millions of years. Here, we use new gravity-driven geodynamic models that reproduce the evolution of the Western Mediterranean, show how the Gibraltar Arc formed and test if it is still active. The results suggest that the arc will propagate further into the Atlantic after a period of quiescence. The models also show how a subduction zone starting in a closing ocean (Ligurian) can migrate into a new opening ocean (Atlantic) through a narrow oceanic corridor. Subduction invasion is likely a common mechanism of subduction initiation in Atlantic-type oceans and a fundamental process in the recent geological evolution of Earth.

Process Prediction and Control by an Empirical Model Based on Equivalent Diffusion for Carburizing or Carbonitriding Processes
Authors: Simons R. W.
Published: March 2024

An empirical model has been developed by studying the rate of case formation for various materials. This model uses the relationship observed between material hardenability and case rate. Material hardenability is based on a modified version of Ideal Diameter by using the nominal steel composition with the exception of holding carbon constant at 0.40% (a rough estimation of the carbon level required for effective case depth). It predicts the level of diffusion needed to meet specification requirements and adjust parameters to optimize process design and resulting product characteristics. Inputs needed for process control are the equivalent diffusion number and a material classification. All times, temperatures, carbon set points and level off parameters are automatically downloaded to the equipment for process execution.
