Authors: Stogov M. V. , Kireeva E. A. , Dubinenko G. E. , Tverdokhlebov S. I.
Published: December 2023

Introduction Assessment of biological characteristics of polylactide/hydroxyapatite (PLLA/HA) biodegradable materials is requiered to specify indications for the use of PLLA/HA composite implants in clinical practice.

The present study was aimed to measure the kinetics of calcium and phosphate release from PLLA and its dependence on polymer structure crystallinity.

Material and methods Four types of biodegradable materials were studied in vitro. Samples of type 1 and type 3 made of crystalline PLLA after annealing contained 25 % and 50 % of HA mass fraction, respectively. Samples of type 2 and type 4 made of amorphous PLLA (without annealing) contained 25 % and 50 % of HA mass fraction, respectively. In every group, 6 samples were tested. The samples were incubated in an aqueous medium at 37 °C for 52 weeks. The rate of PLLA degradation was assessed by the accumulation of lactate monomer in the hydrolysate. The concentrations of calcium ions and phosphate ions were determined for assessment the HA hydrolysis rate. The degree of crystallinity of the polymer matrix was evaluated by scanning calorimetry.

Results The hydrolysis of PLLA and HA in the samples was not simultaneous. The PLLA was hydrolyzed first followed by HA hydrolysis. By the moment of complete hydrolysis of PLLA, there was only 15 % of hydrolyzed HA. The release of calcium ions occurred from the sixth week of incubation for all tested samples, that of phosphate ions from the third week. The total amount of the released calcium ions and phosphate ions decreased in the line: material 3 > material 4 > material 1 > material 2. Calcium ions in the hydrolysates were detected up to 42 weeks of incubation, phosphate ions up to the 52nd week.

Conclusion Higher crystallinity of PLLA achieved by annealing results in increased rate of hydrolysis of HA from PLLA matrix. Biological activity of PLLA/HA implants can be determined by degree of polymer crystallinity and saturation with HA.
Mechanical stimulation of distraction regenerate. Mini-review of current concepts
Authors: Cherkashin A.
Published: December 2023

Introduction One of the key limitations of distraction osteogenesis (DO) is the absence or delayed formation of a callus in the distraction gap, which can ultimately prolong the duration of treatment.

Purpose Multiple modalities of distraction regenerate (DR) stimulation are reviewed, with a focus on modulation of the mechanical environment required for DR formation and maturation.

Methods Preparing the review, the scientific platforms such as PubMed, Scopus, ResearchGate, RSCI were used for information searching. Search words or word combinations were mechanical bone union stimulation; axial dynamization, distraction regenerate.

Results Recent advances in mechanobiology prove the effectiveness of axial loading and mechanical stimulation during fracture healing. Further investigation is still required to develop the proper protocols and applications for invasive and non-invasive stimulation of the DR. Understanding the role of dynamization as a mechanical stimulation method is impossible without a consensus on the use of the terms and protocols involved.

Discussion We propose to define Axial Dynamization as the ability to provide axial load at the bone regeneration site with minimal translation and bending strain. Axial Dynamization works and is most likely achieved through multiple mechanisms: direct stimulation of the tissues by axial cyclic strain and elimination of translation forces at the DR site by reducing the effects of the cantilever bending of the pins.

Conclusion Axial Dynamization, along with other non-invasive methods of mechanical DR stimulation, should become a default component of limb-lengthening protocols.
Prediction of the Upper Flammability Limit of Pure Compounds
Authors: Albahri Tareq A.
Published: December 2023

A quantitative structure-property relation model was developed to predict the upper flammability limit (volume percent in air) of pure compounds, based only in their structures. A group contribution method was used to determine the upper flammability limit (UFL) through an artificial neural network. The method was used to identify the structure groups that have a significant contribution to the target property and concluded that 30 atom-type structure groups can represent the UFL for 550 pure substances. The models input parameters are the number of occurrence of each of the 30 structure groups in the molecule. The model predicts UFL with a correlation coefficient of 0.9996 and average absolute deviation of 0.17 vol %. The results were compared with multivariable regression model and other methods in the literature. The model is very useful and convenient for accessing the hazardous risk potential of chemicals for which experimental data is not available.

Phase filtering as a way to expand the instantaneous analysis band of aviation electronic warfare systems
Authors: Zamarin A.M.
Published: December 2023

Currently, the problem of individual protection of strike aircraft is acute, even if there is a small radar visibility, due to the fact that progress in the development of broadband radar stations radically changes the situation with the possibility of using high-precision weapons against aircraft. To effectively counter such means, it is necessary to ensure the maximum possible expansion of the instantaneous analysis band of aviation electronic warfare complexes while minimizing the weight and size characteristics. The classical techniques of increasing the broadband of aviation electronic warfare complexes have exhausted themselves and cannot provide the required solution to the problem. To significantly increase the broadband of aviation electronic warfare systems, it is necessary to use innovative methods of processing radio signals. An approach to the construction of aviation electronic warfare systems with the achievement of the widest instantaneous analysis band with minimal weight and size characteristics due to the use of phase filtration and the absence of a preselector has been de-veloped. The developed approach can be applied in the design of aviation electronic warfare systems that provide effective suppression of broadband radar stations.

Dentin sensitivity is a problem characterized by brief sharp pain that occurs in response to things like changes in temperature, sweet or sour substances and mechanical factors. This condition significantly affects the lives of patients leading to restrictions and changes in oral hygiene routines. It is crucial for care to understand the causes, symptoms, diagnosis and management of dentin sensitivity. The development of dentin sensitivity is closely related to the structure of teeth which involves the exposure of tubes in the dentin that contain nerve endings sensitive to stimuli. Different theories, such as the theory and direct innervation theory provide insights into how this pain occurs. Diagnosis involves an evaluation of signs and symptoms along with patient history and specific tests to confirm sensitivity. Management options include adjusting behaviors using desensitizing toothpaste or fluoride applications utilizing bonding agents or even undergoing procedures like gingival grafts. These approaches aim to reduce pain and improve the quality of life for individuals affected by dentin sensitivity. Dental professionals play a role, in diagnosing, treating and educating patients about this condition to ensure results and better oral health.

In the field of endodontic therapies, the use of antibiotics, especially in the form of root canal medications, plays a pivotal role in ensuring successful treatment outcomes. This review examines the role of triple antibiotic paste (TAP) in such therapies, delving into its composition, application, and effects on endodontic infections. TAP, a combination of metronidazole, ciprofloxacin, and minocycline, targets the diverse microbial flora in odontogenic infections. Its local application within the root canal space proves more effective than systemic administration, significantly reducing microbial count and aiding in tissue regeneration and disinfection. However, the use of TAP is not without challenges, as it can cause tooth discoloration, particularly due to minocycline, and raise concerns about antibiotic resistance and long-term biocompatibility. This study, conducted through a comprehensive literature search, evaluates the efficacy of TAP, its impact on tooth structure, and its role in maintaining the vitality of diseased pulp. The findings highlight TAP’s significant role in endodontic treatments, emphasizing its benefits in achieving therapeutic goals while acknowledging the need for careful consideration of its drawbacks.

Christoph Christian Sturm’s Theological Reflections on Nature
Authors: Drozdek Adam
Published: December 2023

Christoph Christian Sturm był osiemnastowiecznym duchownym niemieckim żywo zainteresowanym wiedzą przyrodniczą. Jako pastor wykorzystywał tę wiedzę do celów teologicznych: ludzie mogą i powinni wzmacniać swoją wiarę, badając Boże dzieła w przyrodzie, aby zobaczyć wyraźne znaki Jego mądrości, mocy i opatrzności odciśnięte w tych dziełach. Sturm także obszernie dyskutował problem teodycei, wskazując, że dobro zdecydowanie przeważa nad złem występującym w przyrodzie oraz w życiu społecznym i indywidualnym, a to, co postrzegane jest jako zło, to środki Boże użyte w pożytecznych celach
Sexual offenses against minors in the perspective of the amended book VI of the Code of Canon Law
Authors: Mazurkiewicz Dariusz
Published: December 2023

Pojawiające się oskarżenia wobec niektórych duchownych o wykorzystywanie seksualne osób małoletnich sprawiają, że prawodawca kościelny od wielu lat konsekwentnie zaostrza kanoniczne prawo karne. Celem takiego działania jest zapewnienie ochrony dzieciom i młodzieży. Dokonuje się to w trzech obszarach. Pierwszym jest budowanie systemów prewencyjnych, drugim promulgowanie karnych norm materialnych, trzecim tworzenie, na podstawie istniejącego prawa formalnego, lex specialis dotyczącego procedur zmierzających do ukarania sprawców, a tym samym naprawienia zgorszenia i wyrównania naruszonej sprawiedliwości. Ważne miejsce w całym systemie ochrony małoletnich zawierają karne normy materialne. Ostatnia nowelizacja Kodeksu Prawa Kanonicznego zaszeregowała przestępstwa seksualne popełnione wobec małoletnich i osób z nimi zrównanych jako czyny przeciwko życiu, godności i wolności człowieka, a zatem uznała je za najcięższe przestępstwa kanoniczne. Wykorzystując wcześniejsze normy, prawodawca kościelny najpierw spenalizował szeroko rozumiane czynności seksualne popełnione wobec tych osób, dalej jako przestępcze określił działania zmierzające do uwodzenia lub nakłaniania ich do prezentowania się w scenach pornograficznych, wreszcie do tego typu przestępstw zaliczył szeroko rozumiane nabywanie, przechowywanie, prezentowanie i rozpowszechnianie pornografii zawierającej wizerunki małoletnich. Definicja tych przestępstw niejednokrotnie jest szersza niż w ustawodawstwie państwowym. Dodatkowo w ostatniej nowelizacji prawodawca rozszerzył pojęcie podmiotu zdolnego do popełniania tego typu przestępstw. Kolejna nowelizacja prawa kanonicznego zwiększyła zatem zakres ochrony małoletnich i osób z nimi zrównanych.
The message of peace in the literary work of Thomas Merton
Authors: Oleśków Wojciech
Published: December 2023

Według Mertona przyczyną wszelkich konfliktów i wojen są grzechy człowieka, a szczególnie chciwość i egoizm, którym ulegając, człowiek zaczyna uciekać się do przemocy i nienawiści. Przestaje wtedy myśleć racjonalnie, zaczyna się bać o swoją wolność i przez to przestaje ufać sobie i innym. Traktuje drugiego człowieka jak wroga, co nie pomaga w rozwiązywaniu konfliktów w sposób pokojowy. Thomas pokazuje, że zadaniem chrześcijanina jest budowanie świata pokoju. Ważną ideą w tym zadaniu jest niestosowanie przemocy. Jest to postawa duchowa, oparta na miłości do Boga i drugiego człowieka. Jest to działanie bez wrogości i agresji. Taki człowiek dostrzega drugą osobę z jej problemami i trudnościami i pomaga je zwalczać. Jest on znakiem komunii i jedności między ludźmi. Otwiera się na inne osoby, na ich pragnienia i potrzeby. Ciągłym wyzwaniem, które podejmuje jest zauważenie Chrystusa w drugim człowieku i traktowanie go jak brata. Spełniając dzieła miłosierdzia, stara się o przywrócenie zrozumienia i jedności w środowisku, w którym żyje. Dzięki temu staje się ambasadorem miłości i pokoju, szczególnie wśród swoich najbliższych. Odnajduje pokój Chrystusa w sobie, w swoim wnętrzu. To jest podstawa wszelkiej działalności na zewnątrz. Troszcząc się o swój rozwój duchowy, odnajduje misję do podtrzymywania pokoju w świecie.

При сучасних триботехнічних розрахунках істотна роль відводиться теоріям тертя та зношування, що базуються на енергетиці процесів, які відбуваються на зовнішніх шарах деталей, що взаємодіють. Так, енергетичний підхід дозволив сформулювати точку зору, що при динамічному навантаженні двох пружних тіл, в результаті тертя, частина енергії оборотна і йде на розвиток пружних коливань, інша частина енергії непружної взаємодії деталей, на молекулярному рівні, перерозподіляється на інші види енергій і розсіюється в вигляді теплової енергії в навколишнє середовище, при цьому енергія, що залишилася, у разі коливань поверхневих шарів накопичується як незворотна частина потенційної енергії в більш глибоких шарах деталей. Ця енергія при досягненні певного порогового значення сприяє руйнуванню поверхневих і підповерхневих шарів елементів фрикційної пари. Облік температурних ефектів при терті дозволив ряду дослідників при визначенні коефіцієнтів і сил тертя виходити з гіпотези утворення містків зварювання при терті металів та подальшого їх руйнування.

Крім того, набули поширення гіпотези про дифузію атомів при терті елементів кінематичної пари, а також гіпотеза про можливість рекристалізації металів (та інших матеріалів) при кімнатній температурі.

Як узагальнення результатів розглянутих гіпотез автором [1] доведено, що процес тертя має подвійну природу і може бути описаний за допомогою молекулярно-механічної теорії тертя та зношування.

Наявність значної кількості гіпотез і теорій тертя та зношування, як явищ фізичних, обумовлено зручністю енергетичного підходу та надзвичайною складністю самого процесу.

Запропонована робота спрямована на уточнення та в деяких випадках спрощення триботехнічних та супутніх теплових розрахунків.

La literatura sobre conflictos socioambientales explica el estallamiento de disputas por el agua en casos donde hay claros aspectos contenciosos. Sin embargo, poco se ha discutido sobre los conflictos de baja intensidad. ¿Qué explica que los conflictos por agua permanezcan con baja intensidad y no detonen? En este artículo se responde a esta pregunta examinando el caso de la ciudad de Aguascalientes, México, mediante la evaluación de las semejanzas de los marcos perceptuales de los actores como una determinante para no escalar el conflicto en torno a la gestión del agua. En el estudio empírico se detectaron los marcos de percepción de los actores participantes y el uso político que se hace de la gestión del agua en Aguascalientes para explicar un conflicto latente con baja intensidad.

Methodology: The assessment of the implementation of the discussed investments was made on the basis of an analysis of the NPMWT, its last update from 2022 and data from the Central Statistical Office on the condition of sewage infrastructure in Poland. The analysis covered the years 2002-2022 and was of a comparative nature.

Main findings: Despite many investments, Poland still does not comply with the EU law. At the end of 2020 in 675 agglomerations with Equivalent Number of Residents ≥ 2000 (44,3% agglomeration in total) the sewage infrastructure was insufficient or the existing collective sewage systems and sewage treatment plants still did not meet the requirements of the Directive. This does not apply to the entire agglomeration, but only means that the assumed indicators of sewage treatment or sewage system have not been achieved in them.

Application of the study: The analysis contained in the article may be useful for central and local authorities responsible for investments in local infrastructure and students of faculties related to environmental protection and administration.

Originality/Novelty of the study: The subject discussed in the paper concerns important, current issues related to the fulfilment by Poland of the European Union law concerning the standards of urban wastewater treatment. The analysis of the sewage infrastructure was carried out from the point of view of equipping agglomerations measured by the size of the ENR, as well as nationwide – on the basis of data from the Central Statistical Office.
“Zapatista” as a Case of Impossible Identification: Subjectification in Rancière and the EZLN
Authors: Örküp Aykut
Published: December 2023

The Zapatista movement that went public on January 1st, 1994, as a national liberation army occupying several towns in Chiapas, Mexico had long-lasting effects. Apart from inspiring other movements all over the world, the Zapatista movement introduced an alternative to the objective of taking political power through electoral victory or armed struggle. The alternative politics in question was based on equality that entailed a subjectification process. In this way, what allowed for the emergence of the alternative was, in Rancière's terms, politics as subject formation against the police order that attributes the proper places of the parts of society as well as defining the parts themselves. While there is a constant risk of cooptation of the moment of politics by the police order, the continuous subject formation through impossible identification in the Zapatista movement could make the movement the movement of all the excluded by reflecting the struggles of the other excluded groups into the movement and reflecting the movement into those other struggles.

Violation of the Principle of Sovereignty that Legitimizes the Actions of the Security Council
Authors: Florea Dumitriţa , Gales Narcisa
Published: December 2023

The link between sovereignty and international law found its legal embodiment in the principle of sovereign equality of states. The principle of sovereign equality of states is a complex principle, in two ways: both of its components can be considered independent principles. The combination of these elements gave rise to an international legal phenomenon - the principle of sovereign equality of states. It assumes that any state must fully fulfil its international obligations. Within the framework of this principle of sovereign equality, sovereignty itself has regained its definition in the relations of international law. These relations, as a rule, are established between the subjects of international law, i.e. states, but they can also be between states and organizations or only between intergovernmental organizations. The essence of this principle is the rule, according to which the maintenance of international law and order is possible and can be ensured only with full respect for the legal equality of the participants. This means that each state must respect the sovereignty of the other participants in the system, that is, their right on their own territory to exercise legislative, executive, administrative and judicial power without any interference from other states, as well as to exercise independently external politics.
Wooden Language as a Form of Political or Media Communication - An Object of Interdisciplinary Study
Authors: Cătău-Vereș Daniela
Published: December 2023

Analysing the uses of the wooden language in political and media circumstances first requires situating this concept in an appropriate field of scientific research. This field is indeed multidisciplinary, because the wooden language, as a manifestation of language and a phenomenon of communication inspiring speakers with "an ordinary rhetorical feeling" (Krieg-Planque), constitutes a kind of "metalanguage specific to political discourse" (Fiala, Pineira, Sériot, 1989 and Krieg-Planque, 2010), whose analysis thus places us at the crossroads of at least three different disciplines, but close at the same time: linguistics, discourse analysis and information and communication sciences (although the path can take us to sociology, rhetoric or political science). This interdisciplinary rapprochement, as explained by Claire Oger in a chapter of the book Discourse Analysis and Human and Social Sciences, opens up "possibilities of interdisciplinary cooperation in the study of communication phenomena", from a pragmatic and enunciative perspective targeting the practices and discursive strategies of the social and political actors who are at their origin. In this perspective, the study of the wooden language can involve us in a field of interdisciplinary and transdisciplinary analysis at the same time, because it is a question in particular of analysing the modes of manufacture and manifestation of this element integrated in the material of political and social discursive reality.
Korpuslinguistik als Innovation im DaF-Studium und Korpora im DaF-Unterricht. Fallbeispiel Trnava (Slowakei)
Authors: Ďurčo Peter
Published: December 2023

In der universitären Lehre für Studierende der philologischen Fachrichtungen in der Slowakei besteht u. E. ein großes Manko in der Vermittlung der Informationen über die neuesten Technologien bei der Verarbeitung von sprachlichen Daten, was direkt mit dem Bereich der Korpuslinguistik zusammenhängt. Dies steht in krassem Gegensatz zu der Situation z. B. in Deutschland, wo an vielen Universitäten die Kurse zur Korpuslinguistik seit längerer Zeit angeboten werden. Man kann natürlich fragen: Brauchen DaF/DaZ-Lehrende und Studierende überhaupt Korpora? Wenn ja, wozu? Von welchen Korpora könnten sie am meisten Gebrauch machen? Welche Korpustools und Korpuseigenschaften sind am ehesten einsetzbar und hilfreich im Studium und DaF/DaZ-Unterricht? Solche und noch viele andere Fragen kann man im Zusammenhang mit der rasanten Entwicklung im Bereich der sprachlichen Ressourcen und Quellen und dem immensen technologischen Fortschritt im Bereich von verschiedenen Tools für NLP (Natural Language Processing) formulieren.

O podiplomskem študiju in perspektivah raziskovanja nemščine izven nemškega prostora
Authors: Štavbar Simona
Published: December 2023

Po zaključenem študiju germanistike in prevajalstva na Filozofski Fakulteti Univerze v Ljubljani sem se po priporočilu prof. dr. Ade Gruntar Jermol odločila, da podiplomski študij germanistike nadaljujem v Mariboru. Tako sem v študijskem letu 2010/2011 pričela študirati na Oddelku za germanistiko Filozofske fakultete Univerze v Mariboru. Izbrala sem doktorski študij nemškega jezika (študijski program Germanistične študije) in v okviru tega smer Nemški jezik. Pod mentorstvom prof. dr. Vide Jesenšek zaključujem doktorsko nalogo s področja strokovne leksikografije, ki nosi naslov Deutsche lexikographische Terminologie. Theoretische und praktische Aspekte des elektronischen Fachwörterbuchs. Izpite sem v času študija opravljala pri predavateljih z Oddelka in pri priznanih tujih strokovnjakih, ki z Oddelkom v okviru doktorskega študija sodelujejo (prof. dr. Peter Ďurčo, Univerza v Trnavi in prof. dr. Dmitrij Dobrovol’skij, Ruska akademija znanosti, Moskva in Avstrijska akademija znanosti, Dunaj). Sodelovanje s tujimi strokovnjaki, specialisti na posameznem jezikoslovnem področju, je v mojih očeh zelo pomembno, saj gre za poglobitev znanja in dragoceno pomoč pri reševanju strokovnih vprašanj. Za posredovano znanje, usmerjanje v času študija, za predloge o študijski literaturi, preglede seminarskih nalog, svetovanje v zvezi s pripravo doktorske naloge in strokovnih objav sem vsem predavateljem in mentorici zelo hvaležna.
Multicriteria Decision Making for the Selection of Agri-food Service Providers
Authors: Arif Jabir , Jawab Fouad
Published: December 2023

The agriculture sector in Morocco has become a necessity, given the intensification of global competition and the openness of markets to new regulations and requirements. In this regard, we want to put forward the guidelines for the successful agricultural outsourcing strategy in Morocco. The existence of high-performance and potential stakeholders called Agriculture Service Providers (ASP) to meet the specific contractors’ demands is crucial to the strategy’s success. Due to the multitude of MultiCriteria Decision Making Methods (MCDM), decision makers are faced with the challenge of selecting the most appropriate MCDM method, as each of these methods has its own limitations, specifities, and can yield different results when applied to a different problem. The study carried out is a comparative approach between a variety of multi-criteria decision making methods (MCDM) :AHP, TOPSIS, VIKOR and PROMETHEE II using fuzzy logic. A MCDM selection process aims to highlight the advantages and limitations of each method for evaluating the quality of the solution generated. We accomplished this by using assessing’s indicators. Finally, a sensitivity study was conducted to examine the robustness.

Sąsiedzkie wizyty Mikołaja Reja w Wereszczynie i ich historycznoliterackie reperkusje
Authors: Sitkowa Anna
Published: December 2023

W 1585 roku w Krakowie z drukarni Andrzeja Piotrkowczyka (zm. 1620) wyszło pięć utworów Józefa Wereszczyńskiego (po 1531–1598), złożonych w jeden fascykuł i objętych wspólną paginacją, acz samodzielnych typograficznie. Jednym z nich był Gościniec pewny niepomiernym moczygębom a omierzłym wydmikuflom świata tego do prawdziwego obaczenia a zbytków swych pohamowania z Pisma świętego i z rozmaitych autorów zebrany i wydany, w którym został zawarty Żywot Rejów, czyli opis wizyt Mikołaja Reja (1505–1569) w „ojczystym gnieździe” autora. Ów Żywot Rejów, będący karykaturą Nagłowiczanina – pijaka i obżartucha – jest obecnie najbardziej znanym fragmentem z całego piśmienniczego dorobku Wereszczyńskiego.
W artykule podjęto próbę odtworzenia dziejów „odkrycia” wspomnianego passusu, wskazania roli, jaką odegrał on w sposobie wartościowania postawy moralnej i literackiego dorobku Reja w stuleciu XIX, oraz prześledzenia nieustającej popularności Żywota Rejowego w wiekach XX i XXI.
Granica, wojna i miłość w prozie Birutė Jonuškaitė
Authors: Peluritytė-Tikuišienė Audinga
Published: December 2023

Birutė Jonuškaitė, litewska pisarka urodzona i wychowana w powiecie sejneńskim w Polsce, stała się w literaturze litewskiej jedną z najbardziej konsekwentnych autorek opowiadających prawdziwe historie o sąsiedztwie. Po studiach na Uniwersytecie Wileńskim Jonuškaitė pozostała w Wilnie. We wszystkich swoich powieściach opowiada o życiu diaspory litewskiej na ziemiach polskich. W ostatnich utworach, Maranta (2015) i Maestro (2019), tworzy swoisty epos literacki o historycznych związkach między rodzinami litewskimi i polskimi. Związki te rodzą się na litewskiej prowincji, na początku wieku, w miejscu, w którym zbiegają się granice kilku państw, a następnie w ciągu dziesięcioleci rozszerzają się na drogi i stolice Europy i świata. W tych powieściach, dotyczących problemów ogólnoludzkich, granica i pogranicze stają się istotnym problematycznym punktem orientacyjnym.
