Authors: Patil Prakash Santosh , K. K. Dhande  
Published: December 2021

An experimental study was conducted to measure the heat transfer and pressure drop in a rectangular channel emphasizing a compound structure to improve the cooling performance of gas turbine blades. W shaped, semicircular, and multi semicircular shaped ribs with dimples are studied and applied to a lower surface of a channel. The experiment was carried out at a Reynolds number ranging from 10,000 to 32,000 and the ratio of pitch (P) to height (e) of the rib was 10. Also, the ratio of rib height (e) to channel hydraulic diameter (Dh) was 0.187 and the dimple depth (δ) to dimple diameter (D) ratio was 0.2. It was observed that the combination of ribs and dimple channel (compound channel) has an average of 23 % more heat transfer than the ribbed channel. W rib compound channel shows the highest thermal performance and enhanced up to 30 % more heat transfer than semi and multi-semicircular compound channel. friction rise was observed in the compound channel compared to the ribbed channel.

Efficient schemes to represent mathematical model of thin-sheet metal structures jointed by bolted joints for accurately predict the structure dynamic behaviour has been a significant unresolved issue in structural dynamics community. The biggest challenge is to efficiently incorporate the joints local deformation effects on the developed mathematical model via finite element (FE) method. Generally, the joints local deformation typically exerts on the joints mating area. To solve this issue, this paper proposes efficient schemes to represent mathematical model of thin-sheet metal structures jointed by bolted joints with application to accurately calculate the structure dynamic behaviour using FE model updating method. The initial FE model of the assembled structure was developed by employed Fastener Connector (CFAST) in MSC NASTRAN software to represent the bolted joints while, the inclusion of the local deformation effects at the bolted joints mating area was represented by contact elements. Then, the responses obtained from the FE model was evaluated by weight up with experimental data. FE model updating (FEMU) method then was utilised for minimising prediction discrepancies originated from the initial FE model based on the experimental data. The proposed scheme shows the accuracy of the initial prediction was improved from 25.03 % to 14.65 % while the accuracy of the predicted mode shapes via modal assurance criterion (MAC) analysis were above 0.8. Therefore, the findings offer useful schemes for improving the quality of predicted dynamic behaviour, particularly in the thin-sheet metal jointed structure and the developed model can be used with confident for any subsequence dynamic analyses.

Abstract
The foliated low-grade metamorphic rocks of the Triassic Bagolyhegy Metarhyolite Formation, mainly of pyroclastic origin, host post-metamorphic quartz-albite veins containing abundant tourmaline and occasionally rutile/ilmenite. The study of the Ti-oxide-mineralized veins with SEM-EDX revealed an unusual mineral assemblage comprising fine-grained Nb–Ta-bearing oxides (columbite-tantalite series, fluorcalciomicrolite and other Nb–Ti–Y–Fe-REE-oxide minerals) intergrown with Nb-rich polymorphs of TiO2 (anatase, rutile), ilmenite and zircon enriched with hafnium. This high field strength elements (HFSE)-bearing paragenesis is unexpected in this lithology, and was not described from any formation in the Paleozoic-Mesozoic rock suite of the Bükk Mountains (NE Hungary) before. The host metavolcanics are significantly depleted in all HFSE compared to the typical concentrations in felsic volcanics and the mineralized quartz-albite veins have even lower Ti–Nb–Ta concentration than the host rock, so the mineralization does not mean any enrichment. From proximal outcrops of the Triassic Szentistvánhegy Metavolcanics, potassic metasomatized lenses with albite-quartz vein fillings containing rutile/ilmenite are known. We studied them for comparison, but they only contain REE mineralization (allanite-monazite-xenotime); the Nb–Ta-content of Ti-oxide minerals is undetectably low. LA-ICP-MS measurements for U–Pb dating of Hf-rich zircon of the Nb–Ta-rich mineral assemblage gave 71.5 ± 5.9 Ma as lower intercept age while dating of allanite of the REE mineralized quartz-albite veins gave 113 ± 11 Ma as lower intercept age. The REE-bearing vein fillings formed during a separate mineralization phase in the Early Cretaceous, while the Nb–Ta mineralization was formed by post-metamorphic alkaline fluids in the Late Cretaceous., controlled by fault zones and fractures.

Published: December 2021

Abstract
Many of the engineering applications have faced the delicate contact problem in the area close to the forces where it is very difficult to experimentally carry out various measurements and draw important conclusions on the condition of the contact points. In this paper the forced state in the vicinity of the forces for the half-plane will be studied. Furthermore, the qualities displayed by the half-plane under the action of normal forces, tangential forces and the moment caused by a pair of forces will be analyzed, as well as changes in the elastic characteristics for the forced plane state and the deformed plane state.
Personalist Foundations of the Constitutional Principle of the Dignity of Human Person
Authors: Wojtyła Wojciech 
Published: December 2021

Placing the concept of human dignity in the preamble to the Constitution of the Republic of Poland reaffirms it as the foundation of the entire legal system in the state, where it has the status of a value determining application of all norms. Defining sense of human dignity and uncovering its sources is the goal not of the legal doctrine, however, but of philosophy. This paper is an attempt at answering the question, what reality is the person’s dignity from the viewpoint of personalism and what constitutes it. Answering this question is crucial to the process of law institution and application.
Sporne zagadnienia antropologiczne i historiozoficzne w rozważaniach Jacques’a Maritaina
Authors: Kotula Krzysztof 
Published: December 2021

Celem artykułu jest omówienie problematyki związanej z filozofią francuskiego neotomisty Jacques’a Maritaina. Szczególny akcent położony jest na stanowiska krytyczne wobec rozwiązań proponowanych przez Maritaina, ponieważ ten aspekt jest mało rozpowszechniony w polskiej refleksji personalistycznej. Podstawowe pytanie, jakie przyświeca podjętym tu rozważaniom, odnosi się do jakości i zasadności takich Maritainowskich teorii, jak nowa cywilizacja chrześcijańska oraz rozróżnienie na osobę i jednostkę. Całość rozważań osadzona jest na gruncie filozofii klasycznej, ponieważ Maritain starał się być kontynuatorem tej myśli.

Published: December 2021

The aim of the study was to identify features of varying localization of monoamines (catecholamines, serotonin) in the cell structures in tuberculosis-affected lung autopsy samples. Material and methods. 165 cases of secondary pulmonary tuberculosis were studied by examining 2,500 histological preparations from patients aged 30 to 55 years, divided into 5 groups, corresponding to the forms of tuberculosis. The Falck–Hillarp luminescence-histochemical method was used to determine the content of neurotransmitters in lung structures. Results. While using the Falck–Hillarp luminescence-histochemical method, mycobacteria tuberculosis containing catecholamines and serotonin were detected in autopsy material of lungs affected by a specific inflammatory process, as well as neuroamine-containing granular luminescent cells and mast cells. Affected and intact areas of the lungs contain different amounts of monoamines. The number of cells and level of the bioamines studied depends on the form of secondary tuberculosis. It was found that in small forms of secondary tuberculosis (acute focal, fibrous-focal, infiltrative), the number of cells and quantitative parameters of neurotransmitters (catecholamines, serotonin) examined in granular luminescent and mast cells change to rise. In case of lung destructive processes, the level of catecholamines in the structures studied of affected area was higher than in control. The concentration of serotonin in the studied cells lung tissue affected by the tuberculosis process was reduced. Elastic nerve fibers at the sites of mycobacteria were altered as well. They displayed no clear luminescence, looked “swollen”, sometimes lacking varicose veins. Conclusion. Comparing the results of the study with the literature data, it was found that pulmonary tuberculosis occurs as a delayed reaction, and Mycobacterium tuberculosis manifests itself as a corpuscular antigen.

The aim of the study was to examine an association of the rs602662 FUT2 genetic locus with the status of H. pylori infection and development of related diseases (chronic gastritis, gastric ulcer and 12 duodenal ulcer).Methods: The study included 91 patients, divided into two groups - "case" and "control". Criteria for the “case” group enrollment: diagnosis of gastric or duodenal ulcer, chronic non-atrophic gastritis; positive test for H. pylori.The “control” group included patients with episodic complaints of dyspepsia while undergoing a comprehensive examination, with negative test for H. pylori, as well as having no history of former therapy on H. pylori elimination.The study for the presence of the polymorphic locus rs602662 of the FUT2 gene was carried out by the standard TaqMan PCR method on a Real-Time CFX96 Touch amplifier. The follow-up period was 6 months.Results: The main group included 50 patients aged 21 to 50 years, the control group – 41 patients. Patients infected with H. pylori more often noticed symptoms of dyspepsia - in 36%, compared with the control group - 9.7%. A family history of associated diseases in the main group was significantly differed, χ2 = 4.97, p 0.05.To assess the contribution of the rs602662 locus genotype in FUT2 gene to the risk of clinically manifested H. pylori infection, the main group was divided into subgroups. In the distribution of alleles in these groups, significant differences were revealed. Allele "A" has a protective effect regarding the onset of clinical symptoms of dyspepsia. The odds ratio (OR) with the carriage of allele "A" (genotypes A / A and G / A versus G / G) to have clinical symptoms with a positive H. pylori status was 0.175 (CI = [0.049-0.625] chi2 = 7.79 p = 0.0053 ).Conclusion:1. No association of alleles and genotypes of the rs602662 locus of the FUT2 gene with the status of H. pylori infection was revealed.2. Carriage of allele "A" have a significant association with the absence of clinical symptoms in patients with a positive status of H. pylori infection, OR 0.175 (CI = [0.049-0.625] chi2 = 7.79 p = 0.0053).

Authors: Kiessling Benjamin , Kurin Gennady , Miller Matthew Thomas , Smail Kader 
Published: December 2021

This work presents an accuracy study of the open source OCR engine, Kraken, on the leading Arabic scholarly journal, al-Abhath. In contrast with other commercially available OCR engines, Kraken is shown to be capable of producing highly accurate Arabic-script OCR. The study also assesses the relative accuracy of typeface-specific and generalized models on the al-Abhath data and provides a microanalysis of the “error instances” and the contextual features that may have contributed to OCR misrecognition. Building on this analysis, the paper argues that Arabic-script OCR can be significantly improved through (1) a more systematic approach to training data production, and (2) the development of key technological components, especially multi-language models and improved line segmentation and layout analysis./Cet article présente une étude d’exactitude du moteur ROC open source, Krakan, sur la revue académique arabe de premier rang, al-Abhath. Contrairement à d’autres moteurs ROC disponibles sur le marché, Kraken se révèle être capable de produire de la ROC extrêmement exacte de l’écriture arabe. L’étude évalue aussi l’exactitude relative des modèles spécifiquement configurés à des polices et celle des modèles généralisés sur les données d’al-Abhath et fournit une microanalyse des « occurrences d’erreurs », ainsi qu’une microanalyse des éléments contextuels qui pourraient avoir contribué à la méreconnaissance ROC. S’appuyant sur cette analyse, cet article fait valoir que la ROC de l’écriture arabe peut être considérablement améliorée grâce à (1) une approche plus systématique d’entraînement de la production de données et (2) grâce au développement de composants technologiques fondamentaux, notammentl’amélioration des modèles multilingues, de la segmentation de ligne et de l’analyse de la mise en page.
La poétique de la banlieue chez Marina Tsvetaeva
Authors: Delporte Florent 
Published: December 2021

Depuis son départ de Russie, le parcours et la vie de Marina Tsvetaeva sont liés aux banlieues où elle séjourne durant quinze ans de 1923 à 1938, qu’il s’agisse des banlieues pragoises ou parisiennes (Meudon, Clamart, Vanves). Le choix d’y trouver refuge est souvent dicté par des contraintes matérielles et économiques. Mais « s’exiler » hors des centres-villes est aussi une attitude poétique qui n’est pas innocente pour un poète aussi sensible aux lieux que Tsvetaeva. Notre travail a donc pour but de différencier les banlieues où elle vécut, de briser certains préjugés sur ces endroits vus comme lointains et austères et de réfléchir à ce que la banlieue peut représenter dans son imaginaire poétique.
L’Europe de Marina Tsvetaeva, du mythe à la constellation
Authors: Bérenger Caroline 
Published: December 2021

Quels sont les contours de l’Europe de Marina Tsvetaeva ? Quelle est la part européenne d’une poétesse russe dont la parole a des accents universels ? L’Europe de son enfance remonte aux sources de la vocation poétique, baignée de romantisme allemand, dans l’ancien monde de la Russie prérévolutionnaire. C’est le lieu de naissance de la poésie, de la Tauride à la Crimée de Koktebel, des mythes antiques aux avant-gardes de l’âge d’argent, dans le sillage de la figure tutélaire d’Alexandre Pouchkine. L’Europe de la maturité est aussi celle de l’exil en 1922, puis de l’émigration en France. Marina Tsvetaeva devenue apatride est une étrangère. Tandis qu’elle traverse les frontières, elle célèbre dans son œuvre l’esprit tsigane et la vie nomade. Elle va vivre dans sa chair l’irruption de la barbarie et l’effondrement du continent. C’est alors qu’une troisième Europe se profile sur les ruines de l’ancienne, celle de la renaissance posthume qui prépare sa réception future. La réparation se fait par la filiation avec Maria Rainer Rilke, dans la communauté des poètes, un « monde toute-langue » animé par une « nostalgie de la culture universelle ». Ainsi se dessine la carte évolutive d’un continent intérieur, « Mon Europe » aurait dit Tsvetaeva, une patrie spirituelle, un topos poétique, une « topographie de l’âme ». Au-delà des ruptures géographiques et historiques, au centre et dans les marges, une trinité continentale émerge, l’« Eurussie » de Marina Tsvetaeva, le destin européen d’une œuvre poétique dont la russité non négociable est une percée dans l’universel.
NEUROCIENCIAS FRENTE AL DERECHO PENAL
Authors: Castro Sabrina E. 
Published: December 2021

Los debates sobre la relación entre las Neurociencias y el Derecho Penal pueden parecer muy actuales y novedosos, sin embargo, bien podría sostenerse que los orígenes son de larga data. Siempre ha existido el debate entre “determinismo vs. indeterminismo”, esa idea de que el mundo está predeterminado -de que todo tiene una causa y se puede explicar conforme leyes naturales o no. Este debate tradicional, podría trasladarse a la actualidad. Sin embargo, ya no se tratará de un debate tan filosófico ni cosmológico, sino que se tratará de un debate más objetivo enlistado tras métodos empíricos, basados en la experiencia y en la observación concreta de determinados hechos. Concretamente, se tratará de un debate que tendrá que ver con los datos concretos que nos aportan las neurociencias, y en qué medida ello influye – o podría influir- en el Derecho Penal actual, a la vez que replanteará de qué manera la incorporación de los datos aportados por otras ciencias y disciplinas condicionan – o podrían condicionar- para mantener el Derecho Penal que tenemos hoy en día. De esta manera, a lo que afecta el debate es
al mantenimiento o no, de un Derecho Penal de la Culpabilidad por el hecho, es decir que el debate versará sobre el fundamento material de la culpabilidad, sobre la idea de que el ser humano solo es culpable en la medida en que actúa libremente.

Abstract
Aftershock-monitoring networks deployed in the epicentral area of a damaging earthquake play important roles in earthquake early warning and ShakeMap estimation, which contribute to hazard mitigation. Using distributed acoustic sensing (DAS) technology with dark fiber can significantly reduce deployment time and cost, and improve spatial sampling, both of which help capture more aftershocks. In this study, we used a 7.6 km dark fiber in Tangshan, China, to monitor seismicity after the 12 July 2020 Ms 5.1 earthquake. The DAS array detected dozens of earthquakes missed by the local permanent network that doubled the number of aftershocks. The relocated aftershocks are distributed mainly north of the DAS array, and the ground-motion pattern changes also hint small-scale features. Our successful results demonstrate the feasibility of using DAS and dark fiber for rapid postearthquake response.
Evaluation of cell surface hydrophobicity and biofilm formation as pathogenic determinants among ESBL producing uropathogenic Escherichia coli
Authors: Anandkumar H  , Nigudgi Amaresh , Hajare Vinay , Biradar Sunil 
Published: December 2021

The attachment of the bacteria to the host cell and ability to invade the cell are regarded as important steps in the infectious process. The hydrophobicity of the microbial surface plays a critical role in the adherence of bacteria to the surface. The ability of biofilm formation can increase survival chance of microorganism, as cell growing in biofilm are highly resistant to the components of the immune system and many antimicrobial agents. Infection caused by ESBL- producers are associated with severe adverse outcomes and may be related to increased virulence of these strains.: A total of 100 urinary were selected for the study, of which 50 strains were from ESBL producers and 50 from non- ESBL-producing uropathogenic(UPEC) strains. The urinary isolates that were resistant to at least one of the three indicator cephalosporins (cefotaxime, cefpodoxime and ceftazidime) were tested for ESBL production by quantitative E-strip method. All the 100 urinary strains were tested for cell surface hydrophobicity (CSH) by salt aggregation method and Biofilm production by tissue culture plate method.Among ESBL producers, 19 (38%) were CSH positive and 34 (68%) were biofilm producers. However among non-ESBL producers, 05 (10%) were CSH positive and 12 (24%) were biofilm producers. Statistically significant difference (&#60;0.001) was seen in the occurrence of CSH and biofilm production between ESBL and non ESBL producing UPEC isolates.In the present study, it was found that the ESBL producing isolates had a higher ability to form biofilm and CSH; both of them are among the important virulence factors associated with cell surface adherence which is the first step in bacterial infection.
