Published: March 2023

Due to its excellent textural features, non-toxicity, low cost and high uptake capacity, biochar has been synthesized from various biomasses and utilized as a biosorbent to remove hexavalent chromium (Cr6+) from contaminated water. Herein, activated eucalyptus biochar (AEB) was prepared via a pyrolysis-chemical activation process and then used as a less expensive biosorbent to adsorb Cr6+ ions from an aqueous solution. Proximate, ultimate, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and Brunauer–Emmett–Teller (BET) analyses were employed in appraising the biosorbent characteristics. Furthermore, response surface methodology (RSM) and adaptive neuro-fuzzy inference system (ANFIS) were applied to establish the best operating conditions. Based on the results obtained, there was little discrepancy between the observed data and the data predicted by RSM and ANFIS approaches. In terms of prediction accuracy, ANFIS (MAE = 2.512 and R2=0.9200) was superior to RSM (MAE = 2.512 and R2=0.9002). Under best-optimized conditions (initial Cr6+ concentration = 38.14 mg/L, biosorbent dosage = 1.33 g/L and pH = 4.35), which were offered by the ANFIS–ACO technique, the maximum percentage removal of 99.92 ± 0.18% was achieved. The AEB performed exceptionally well due to its better textural characteristics, well-developed porous framework, and dominance of active surface functional groups, which were confirmed by BET, SEM, and FTIR analyses. The comparison of RSM, ACO and GA for process parameter optimization has not been reported in the open literature for Cr6+ adsorption by AEB and hence has been shown in this study.
On Non-Zero Vertex Signed Domination

Published: March 2023

For a graph G=(V,E) and a function f:V→{−1,+1}, if S⊆V then we write f(S)=∑v∈Sf(v). A function f is said to be a non-zero vertex signed dominating function (for short, NVSDF) of G if f(N[v])=0 holds for every vertex v in G, and the non-zero vertex signed domination number of G is defined as γsb(G)=max{f(V)|f is an NVSDF of G}. In this paper, the novel concept of the non-zero vertex signed domination for graphs is introduced. There is also a special symmetry concept in graphs. Some upper bounds of the non-zero vertex signed domination number of a graph are given. The exact value of γsb(G) for several special classes of graphs is determined. Finally, we pose some open problems.

Published: March 2023

The Czech Republic's changing presidency
The presidency stands out in the Czech constitution. Even though emphasis should be placed on a strong continuity running back to Masaryk, an analysis of the political situation since 1989 reveals significant changes, especially after the partition of Czechoslovakia. The presidency is a key institution in a parliamentary sort of system where the government has preeminence. The head of state's place and role are now changing as a function of politics and in line with the acting president's personality and conceptions. A political president, V. Klaus, has succeeded V. Havel, whose presidency had a strong moral dimension.
La (re)construction du fait régional au Monténégro : productions et représentations territoriales entre héritage et idéologie

The (re) construction of regionalisms in Montenegro: The production of territorial issues - between a heritage and an ideology
Given the changes in international borders following the breakup of Yugoslavia, new "minorities" emerged in Montenegro in a context of war and radical national discourses. Owing to the territorial grouping of these minorities, national and territorial claims took the form of virulent ethno- regionalisms.This holds in particular for the Muslims in Sandzhak, Albanians in Ulcinj and Tuzi, and Croats in Kotor. A new situation in Montenegro arose with the coming to power of the anti-Milosevich government in 1998 and the country's long march toward independence. An original situation in the Balkans has cropped up as, early on, minorities adhered to plans for Montenegrin independence. The oscillation between, on the one hand, an ethno-regionalism characterized by demands for autonomy or secession and, on the other hand, a local regionalism characterized by the defense of local interests and a de facto allegiance to central authorities can, by using the technique of mental maps, be detected in the ideas that Montenegrin peoples have of regions.
Régionalisme impossible, régionalisation improbable : la gestion territoriale en Turquie à l'heure du rapprochement avec l'Union européenne
Authors: Massicard Elise 
Published: March 2023

Impossible regionalism, improbable regionalization:
Territorial management in Turkey during the rapprochement with the EU
The opening of negotiations for Turkey to join the EU has coincided with important local government reforms. These reforms respond, in part, to fuzzy European demands but, even more, to internal "logics". Though reinforcing intermediate levels of authority, they do not lead to regionalization since a deep political and institutional tradition of centralization blocks any regionalism. These institutional changes let the political and administrative system intact. The major factor that might change the territorial patterns of resources is the implementation of a regional policy like the EU's. Given its resistance and adaptations, Turkey seems to be following the path taken by new EU member-states.

Endometriosis is a chronic inflammatory disease characterized by the presence of endometrial-like tissue outside the uterine cavity. Deep endometriosis is a lesion of the tissue of the abdominal cavity, similar to the endometrium, which spreads on the surface of the peritoneum or under it, is able to penetrate into adjacent structures and is accompanied by fibrosis and a violation of normal anatomy. Treatment of endometriosis includes pain reduction, improvement of fertility due to hormonal suppression of the level of endogenous estrogens, proapoptotic and anti-inflammatory effects on endometrioid tissue, as well as surgical removal or destruction of endometriosis foci and pelvic inflammatory process. But despite numerous studies, the optimal management of patients with deep endometriosis is still the subject of numerous discussions.
An analysis of modern recommendations for the management of patients with deep endometriosis, the role of medical and surgical treatment in reducing the symptoms of pelvic pain and improving the fertility and quality of life of patients was carried out.
The standardization of the procedure for surgical treatment of deep endometriosis proposed by us will help reproduce the sequence of surgical steps, which will lead to balancing the completeness of excision of tissues affected by endometriosis, and prevention of intra- and postoperative complications, preservation of female fertility.

Published: March 2023

<p>Image registration is a technique of matching and superimposing of features, which can be better applied to high-level vision tasks. However, high-level vision tasks often pay more attention to analysis of target areas. In summary, we rethink the collaborative relationship between image registration and high-level vision tasks, and propose a local registration strategy for constructing a robust adaptive attention gauge fields, and construct robust adaptive attention gauge fields to register images focus more on important target areas. In order to improve the robustness and timeliness of the algorithm for feature matching of target areas in complex environments, we propose a robust adaptive probability distribution(RA), and construct robust adaptive mixed model expectation maximum attention(RAMM-EMA). In order to make robust adaptive parameters to reach the global optimum in deep learning, we designed a simulated annealing method to optimize the robust adaptive parameters during training. In order to focus on important regions in the image as much as possible, propose a feature fusion map with weak boundaries and probabilistic properties, called Robust Adaptive Attention Gauge Fields(RAA-Gauge Fields). High-level vision tasks experiments on image fusion, object delect and 3D-reconstruction, the method presented in this paper is the most helpful, and registration effect of the target areas perform best under more extreme conditions. </p>
Orthogonal and Non-Orthogonal Multiple Access for Intelligent Reflection Surface in 6G Systems
Authors: Jiang Wei 
Published: March 2023

<p>Intelligent reflecting surface (IRS) is envisioned to become a key technology for the upcoming six-generation (6G) wireless system due to its potential of reaping high performance in a power-efficient and cost-efficient way. With its disruptive capability and hardware constraint, the integration of IRS imposes some fundamental particularities on the coordination of multi-user signal transmission. Consequently, the conventional orthogonal and non-orthogonal multiple-access schemes are hard to directly apply because of the joint optimization of active beamforming at the base station and passive reflection at the IRS. Relying on an alternating optimization method, we develop novel schemes for efficient multiple access in IRS-aided multi-user multi-antenna systems in this paper. Achievable performance in terms of the sum spectral efficiency is theoretically analyzed. A comprehensive comparison of different schemes and configurations is conducted through Monte-Carlo simulations to clarify which scheme is favorable for this emerging 6G paradigm. </p>

Auslegung von Druckfedern durch neu entwickelte Festigkeitsschaubilder verbessert
Authors: Petrich Martin , Kletzin Ulf 
Published: March 2023

inhalt Für die Auslegung von zyklisch beanspruchten Schraubendruckfedern enthält die Norm DIN EN 13906–1 Goodman-Diagramme mit zulässigen Spannungen. Deren Ermittlung liegt Jahrzehnte zurück, weshalb die Norm im Vergleich zum heutigen Stand der Technik zu Ungenauigkeiten in der Federauslegung führt, die je nach Material größtenteils konservativ, teilweise aber auch kritisch im Betrieb sind.

Um diese Unzulänglichkeiten zu überwinden, wurden die zulässigen Spannungen in einem Forschungsvorhaben mithilfe der 2020 erstmals erschienenen FKM-Richtlinie für Federn neu ermittelt, mit Schwingversuchen validiert und anschließend neue Schwingfestigkeitsdiagramme erstellt. Weiterhin wurde eine Übertragung der zulässigen Spannungen in den neuen Diagrammen auf andere, ähnliche Schraubendruckfedern entwickelt.

Der Beitrag soll die Ergebnisse des Vorhabens zusammenfassen und einen Eindruck vermitteln, welche Einflüsse auf die Schwingfestigkeit nun berücksichtigt werden können, um mit besser passenden Schaubildern konkurrenzfähige Federn in kürzerer Zeit und mit weniger Versuchsaufwand nach dem aktuellen Stand der Forschung auszulegen.
“The Foundling Trade” and the Life of the Fosterlings of the St. Petersburg Foster Home in the Villages of the St. Petersburg Province in the Second Half of the 19th — Early 20th Centuries

В статье дается краткая характеристика питомнического промысла, развивавшегося на территории Санкт-Петербургской губернии во второй половине XIX — начале XX века, а также его влияние на жизнь крестьянского населения западных уездов столичной губернии. В ходе исследования проанализирована государственная политика в отношении крестьянских семей, занимающихся воспитанием детей из петербургских сиротских учреждений, выявлены правовые механизмы, закрепленные на законодательном уровне передачи детей-сирот сельским жителям. Предпринята попытка на основе сохранившихся документов, воспоминаний современников и земской публицистики представить элементы повседневности (в том числе домашней жизни) питомцев грудного и более старшего, подросткового возраста, отношение к ним их воспитателей и кормилиц. Особое внимание уделено анализу публикаций в первой земской газете России «Гдовско-Ямбургский листок», касающихся проблем положения сирот в Санкт-Петербургском учебном округе. В делопроизводственных документах, заметках и статьях представителей общественности дана преимущественно отрицательная оценка деятельности воспитательного дома, в том числе раздачи питомцев по деревням, что во многом обусловливалось необходимостью реорганизации данных учреждений и форм их работы.
The article gives a brief description of the foundling trade that developed on the territory of the St. Petersburg province in the second half of the 19th — early 20th centuries, as well as its impact on the life of the peasant population in the western districts of the St. Petersburg province. The study analyzes the state policy in relation to peasant families involved in raising children from St. Petersburg orphanages. It identifies legislative mechanisms which enabled the placing of orphans to rural residents. The article analyzes surviving documents, memoirs, and zemstvo journals to discover basic elements of everyday life (including home life) of infants and older adolescents, the attitude of their educators and nurses towards them. The article scrutinizes publications in the Gdovsko-Yamburgsky listok (the Gdovsko-Yamburg Leaflet), the first Russian zemstvo newspaper, discussing orphans’ problems in the St. Petersburg educational district. The analysis of office documents, notes and articles written by members of the public shows that orphanages, whose activities received a predominantly negative assessment, needed dramatic reforms.
Peddling Newspapers and Journals in Russia in the Early 20th Century
Authors: Крылова Е.Н. 
Published: March 2023

В статье рассматривается вопрос организации разносной торговли периодическими изданиями в России в начале ХХ века, основное внимание уделено разносной торговли в столичных городах — Санкт-Петербурге и Москве. Цель исследования — определить основные виды разносчиков периодических изданий. На основе имеющихся источников автор выделяет четыре вида разносчиков, занимающихся распространением газет и журналов в крупных городах Российской империи. Автор приходит к выводу, что законодательство, регулирующее организацию разносной торговли произведениями печати, было противоречиво, что создавало предпосылки для возникновения разных форм распространения газет и журналов в пределах крупных городов. Полученные результаты могут быть использованы, в первую очередь, при подготовке общих курсов по истории России, чтении курсов лекций и спецкурсов по истории журналистики.
The article treats the issue of peddling newspapers and magazines in Russia in the early 20th century. The article focuses on the peddling trade in Moscow and St. Petersburg. The aim of the research is to identify types of peddlers dealing with periodicals. The analysis of available sources enables the author to identify four different types of peddlers who sold and distributed newspapers and journals in big cities of the Russian Empire. Thee author concludes that the laws regulating the peddling trade were rather inconsistent, hence there appeared different forms of peddling in big cities. The obtained results can be used to prepare lectures and seminars on Russian history and history of journalism.
