Abstract
Over the almost 190 years-long research of the Ditrău Alkaline Massif (Eastern Carpathians, Romania), felsic rocks have been regarded as homogeneous, uniform units of the igneous complex. Nevertheless, our detailed textural study revealed that the felsic suite (diorite–alkaline feldspar syenite and nepheline-bearing syenite–granite series) cropping out north of the Jolotca Creek valley is more heterogenous at micro-scale than previously thought. This heterogeneity partly derives from abundant mafic mineral-rich clusters; nevertheless, felsic minerals also exhibit various, remarkable textural features. Outcrop to micro-scale traits of felsic crystal settling, mafic mineral aggregates and flow fabrics along with metamorphic country rock xenoliths suggest that the studied rocks crystallized under dynamic magmatic conditions. Cumulate formation, shear flow, convection currents as well as various open-system magmatic processes (e.g., magma recharge, magma mixing and mingling, crystal or mush transfer and recycling, country rock assimilation) played a significant role in the petrogenesis of the examined felsic suite.
Based on field observations as well as on the microtextural relationship of the minerals, two major groups of felsic rocks were distinguished: (1) felsic rocks (lacking or containing sparse mafic minerals) spatially associated with mafic rocks and (2) felsic rocks (with mafic minerals and clots) spatially unassociated with mafic rocks. Rocks of the former group are dominated by plagioclase, accompanied by minor alkaline feldspar, biotite and accessory titanite. Distinct structural and textural features suggest the physical accumulation of the rock-forming phases. Such textural properties can also be observed in some rocks of the second group. Isolated mafic minerals are rather scarce in the latter; nevertheless, different types of aggregates made up of either identical or various mafic phases are more common. Clustered minerals are either intact or show different stages of alteration.
A detailed petrographic study of the above-mentioned peculiarities has been implemented in order to define their potential origin(s) and petrogenetic significance.

AbstractFerroelectric nanoparticles, due to their high non-linear optical response, are of considerable practical interest for their use as nanoprobes for the study of biological materials by multiphoton microscopy methods. To prevent toxic effects, it is necessary to modify the surface using biocompatible polymers. Here we report the results of the study on the effect of surface modification of BaTiO3 nanoparticles with hydrolyzed chitosan obtained from shrimp exoskeletons (Penaeus vannamei). It was found that increasing of the hydrolyzed chitosan concentration in the solution during surface modification from 1 to 3% leads to a significant reduction in nanoparticle agglomeration, while the intensity of the second harmonic generation changes insignificantly.

Published: April 2022

AbstractIn hot-humid climates, porous external surfaces of the buildings with high water sorption capabilities could contribute to the surface temperatures reduction through the release of latent heat by evaporative cooling. On the other hand, compact and low permeable finishing materials could have mechanical and durability benefits respect to the underlying supports, for example reducing the permeability to degrading agents. In this paper, the properties of lime base coat renders with pore modulating additives (sepiolite and colloidal nano silica) have been surveyed to evaluate their effectiveness in water absorption, thermal performance, and the fulfilment of mechanical requirements for the application on the external side of the walls. A traditional lime–sand formulation was taken as reference. After preliminary tests on workability and shrinkage, the optimal mix designs were selected and the samples were subjected to several mechanical and thermo-hygrometric tests, before and after accelerated aging. The results allowed demonstrating that the use of sepiolite in substitution of sand, enhances the render ductility, thermal resistance and water uptake but worsens its mechanical stability, increasing the shrinkage effects and slightly reducing the ultimate strength values. The addition of colloidal nano silica, either to lime–sepiolite or to lime–sand renders, fails to produce any improvement in their either physical or mechanical behavior. Mixed formulations (lime–sand with sepiolite and nano silica) behave as simple lime–sand solutions, showing optimal compressive and flexural strength but reduced water uptake capabilities. This demonstrates that the presence of sand prevails in the performance of the render, and that the adoption of other additives doesn’t worth the cost for the benefit presented.

Authors: Jiménez Ramírez Milton César 
Published: April 2022

La democracia constitucional es un procedimiento y una práctica que dispone la mayor participación posible de los ciudadanos en los asuntos públicos, así como la búsqueda dedecisiones legitimas a través de un diálogo igualitario e incluyente. La democracia constitucional es la garantía del autogobierno popular en consonancia con la protección de losderechos humanos. Este escrito hará una aproximación a los principales impactos generados por la crisis sanitaria del COVID-19 sobre la democracia constitucional. Por ello, bajo un método cualitativo (documental) con enfoque analítico, hermenéutico y crítico se procederá a: (i) Analizar el concepto de democracia constitucional y sus principales desviaciones; (ii) Identificar la crisis sanitaria como un fenómeno que impulsa la insuficiencia del diseño constitucional, lo que se expresa desde el ámbito político, social e institucional. Como conclusión se mostrará la necesidad de repensar el diseño constitucional, especialmente desde la deliberación y el reforzamiento del sistema de controles al poderpresidencial.
La constitucionalización de la responsabilidad y su proyección en la jurisprudencia del Consejo de Estado colombiano
Authors: Arenas Mendoza Hugo Andrés 
Published: April 2022

Este artículo de investigación tiene por objetivo demostrar que a partir del artículo 90 de la Constitución se ha producido el fenómeno de la constitucionalización de la responsabilidad estatal y, concretamente, la modificación de la jurisprudencia del Consejo de Estado. La metodología aplicada es la inductiva y se parte del análisis histórico para demostrar como el Consejo de Estado introdujo la figura de la constitucionalización en sus decisiones, su argumentación y su aplicación en sus sentencias. A partir de esto, se evidenció que el Consejo de Estado aplica las directrices de la norma fundamental, en cuatro ámbitos principales: 1. El impacto de la constitucionalización en los elementos configuradores de la responsabilidad; 2. La importancia de la introducción del control de convencionalidad; 3. La clasificación de los daños inmateriales y la creación de la de los daños a bienes constitucional o convencionalmente protegidos y 4. La reparación integral del daño.
Formation of a Quasi-Marxist Legal Understanding in Soviet Legal Science in the 1920s–1930s
Authors: Sheptalin A. A. 
Published: April 2022

The paper is devoted to one of the clearest examples of misconceptions and falsifications known to the science of the theory of state and law — the ongoing identification of the Soviet (Marxist-Leninist) legal understanding with Marxism. The relevance of the topic is also due to the need to correct the prevailing ideas about «Marxist» (materialistic) concepts of legal understanding and the theory of the origin of the state and law. The subject of the study is the process and general causes of the distortion of the Marxist legal understanding in Soviet jurisprudence in the 1920s-1930s. The aim of the work is to identify the main differences between the authentic Marxist legal understanding and the quasi-Marxist Soviet legal understanding, as well as to attract attention of the scientific community to the problem of their unjustified identification.Based on a wide range of legal literature of the early Soviet period, the course of the development of the Marxist debate on the understanding of law and the reasons for the appearance of the quasi-Marxist definition of law from 1938, which became the ideological basis and model for subsequent definitions for several decades, is considered. The main contradictions between the Marxist and Soviet understanding of law are shown, primarily related to the «nationalization» of the institution of law, the identification of law and law, ignoring the production and economic conditionality of law, as well as recognition of the key role of state power, force and coercion in the genesis of law.According to the author, the authority of the Lenin’s works, then Stalin’s ones initially influenced the Soviet legal understanding. It later developed along a simplified positivist path and significantly distanced itself from Marxism, because the Soviet theory of state and law was formed post factum on the foundation of state legal practice, consolidating and sacralizing decisions developed during not scientific, but political discussion.

The aim in our pilot research study is to evaluate accuracy of implant placed using guided surgery with an ingeniously developed guide, therefore the deviation between the virtual planning and the postoperative implant position has to be evaluated.7 patients were randomly selected from the Out Patient Department of our hospital and 10 implants were placed in them with the help of an indigenously developed 3D surgical guide. Pre-operative & Post-operative CBCT was compared in a software for the evaluation of precision. Site specific comparative evaluation was done in 4 parameters i.e., entry deviation, apex deviation, depth deviation in single plane and angulation between long axis of placed and planned implants.The results were tabulated and standard statistical analyses were done. Mean ± Standard deviation of entry deviation were 0.4 ± 0.29 mm., exit deviation 0.7 ± 0.33 mm., angulation deviation 3 ± 1.7 deg. And depth deviation 0.2 ± 0.13 mm. All the P values were &#60; 0.001. So statistically highly significant fewer chances of errors are seen in cases where this surgical guide was used.This evidence backed ingeniously designed implant template reliably guides precise & predictable implant placement in each & every case thus promulgating the best care for all concept further with a vision for the future.
Effect of different angulation of forces on mini implant and abutment at various levels
Authors: Ramagoni Naveen Kumar 
Published: April 2022

The objective of the study was to evaluate the effect of varying loads of forces at different angulation at various levels of orthodontic mini implant system by using finite element analysis. A 3-dimensional model of the mini implant was constructed to simulate force magnitudes and directions, screw diameters and lengths, and implanted depths of mini implants. Finite element study was conducted with horizontal forces of 100, 150, and 200 g were applied to the mini implant and abutment at angulations 90° and 120. Von Mises stress, strain and displacement values were then evaluated using the ANSYS software. Both stress and displacement increased with increasing the amount of loading force. These 2 indexes were linearly proportional to the force magnitude and produced the highest values when the force was 200 g applied at 120° to the long axis of the miniimplant. The peak deformation and von Mises stress was concentrated on the miniscrew at the cervical level under 200 g at 120°. A wider screw diameter provided superior mechanical advantages. No remarkable differences in the strain distribution were observed at both angulations. However, the stress distribution of the abutment models showed a remarkable difference as compared with the models of mini implant. The high-level area (shown in orange) was localized to the head of the implant and the abutment (cervical part). Compared with 90° group, the orange coloured area was easily observed more in the cervical part of abutment. The von Mises stress values in the MI, were found to be lowest under 100 g force at 90°. Higher initial loading on the mini implant should be avoided and horizontal force on the cervical level of MI should be prevented or minimized for better stability. The abutment has maximum stress concentration which is significantly useful in decreasing the stress concentration on the bone, and has a buffering action on MI. Force range used is within clinically recommended levels; however, the increase in load causes a proportional increase in the stress values.
The Right to a Fair Trial in the Area of Russian and Austrian Public Law
Authors: Karamanukyan D. T. , Chvosta P. 
Published: April 2022

The research paper examines the legal category of procedural (proceedings) law “Right to a Fair Trial” as a fundamental element of the European Human Rights Convention and the judicial practice of the European Court of Human Rights. The Authors concentrate mainly on the general part of Article 6 and focus on crucial aspects of the mentioned right which have become significant for the daily legal practice in the Russian Federation, Republic of Austria and other member states. In the domestic Russian legal doctrine, there are sectoral and international legal studies devoted to the Convention for the Protection of Human Rights and Fundamental Freedoms, the functioning of the European Court of Human Rights and the legal nature of its acts (A. Abashidze, E. Alisevich, M. Biryukov, S. Kalashnikova,V. Tumanov, K. Aristova).Along with this, from the standpoint of conventional rights, Russian legal scholars studied the procedural features of the implementation of acts of the European Court of Human Rights and the application of conventional norms in civil, arbitration and criminal cases (I. Vorontsova, T. Solovieva, M. Glazkova, S. Afanasiev, L. Volosatova, E. Iodkovsky, K. Mashkova, etc.).The private-scientific research methods used by the Authors in the presented scientific article, predominantly comparative, require the study of the works of foreign scholars in the field of law, which include P. Leanza, O. Pridal, D. Spielmann, V. M. Zupancic, H. Mosler, A. Buyse. Despite the rather large volume of doctrinal sources on the nature and implementation of conventional rights, the issues of applying the right to a fair trial in administrative disputes and cases arising from public law relations have not become the subject of scientific research. The empirical basis of the study conducted by the Authors is composed of 66 pilot judgments and other acts of the European Court of Human Rights on complaints from individuals against Russia, Austria, France, Finland, the Netherlands, Great Britain, Switzerland and other member states of the Council of Europe; judicial acts of the courts of Russia, Austria and other European countries. It is concluded that the practice of Article 6 of the European Human Rights Convention by the European Court has had a remarkable and sometimes unprecedented impact on public law and law enforcement activities of the European countries that are parties to the Convention. As Russian and Austrian experience shows, the decision of the European Court on behalf of the enforcement of Article 6 in one specific case can induce the state not only to adopt a separate law, but also to carry out serious institutional changes. Many such examples are given below by the Authors, which testify that the decisions of the European Court are able to act as a powerful law-forming force on the national level.

Published: April 2022

Abstract
Background:
Studies have demonstrated the efficacy of oxygen delivery-guided perfusion (ODGP) in preventing postoperative acute kidney injury, but the benefit of ODGP for delirium has not been confirmed. We retrospectively investigated the risk factors for postoperative delirium in patients who underwent ODGP (with oxygen delivery index [DO2i]>300 mL/min/m2).
Methods:
Consecutive patients who underwent on-pump cardiovascular surgery with ODGP between January 2018 and December 2020 were retrospectively analyzed. In addition to examining patients DO2i during cardiopulmonary bypass (CPB), we quantified the two primary DO2 components – hematocrit (Hct) and pump flow. Delirium was defined based on the Intensive Care Delirium Screening Checklist (ICDSC). Patients were divided into three groups: no delirium (ICDSC score = 0), subsyndromal delirium (ICDSC score = 1–3), and clinical delirium (ICDSC score ≥ 4).
Results:
Multivariate analysis identified only age and the cumulative time below the Hct threshold of 25% as predictive factors of postoperative delirium. Although patients with higher ICDSC scores had greater hemodilution during CPB, ODGP resulted in a higher pump flow, and DO2i was maintained above 300 mL/min/m2, with no significant difference between the three groups.
Conclusions:
A low Hct level during CPB with ODGP and age were independent predictors of postoperative delirium. Further investigations are needed to determine the ability of ODGP to prevent low Hct during CPB.
