Ese tiempo de ser jóvenes
Authors:   , Cuchan Natalia Soledad
Published: February 2022

La presente tesis de maestría reconstruye y analiza, a través de un estudio de caso, las experiencias de convivencia y participación que construyen jóvenes y adultos en escuelas secundarias rurales del sudeste de la provincia de Buenos Aires. El contexto rural, poco visible en las investigaciones, se encuentra atravesado por la redefinición de la concepción tradicional sobre “lo rural” y el crecimiento del nivel de educación secundario en estos territorios, a partir de la progresiva extensión de su obligatoriedad. El estudio asume una perspectiva micro política de la vida escolar, intentando aportar a la reflexión sobre las interacciones que subyacen entre las políticas educativas y las experiencias escolares, desde la singularidad de sus contextos. En cuanto a lo metodológico, recupera estrategias del enfoque etnográfico y de la investigación social antropológica, combinando prácticas de observación participante, entrevistas semiestructuradas y grupos de discusión, con el análisis de fuentes secundarias. Los desafíos de la democratización de las prácticas escolares dialogan con la familiaridad de las comunidades rurales, no por ello exentas de conflictos y permeadas, a su vez, por cuestiones de género que moldean las relaciones institucionales. La complejidad de los vínculos que implica el encuentro con otros ha permitido observar cómo la convivencia se dirime en estas escuelas ante ciertos “nudos” que visibilizan la autorregulación y la ausencia de regulación, ciertas “sospechas” sobre las sanciones que actúan como fuerzas que intentan ordenar los vínculos, pero también formas de disolver conflictos. Las acciones y situaciones en las que las juventudes rurales se reconocen participando remiten a la cotidianidad y a la sociabilidad entre pares, en ocasiones vinculadas a las propuestas de los centros de estudiantes. Iniciativas ligadas a las mejoras edilicias o proyectos recreativos, son interpretados como “básicas” por los adultos, pero demuestran la importancia del tiempo de estar en la escuela para estas juventudes. La comprensión de la política y las expresiones de politicidad de los actores se encuentran signadas tanto por su distanciamiento con lo escolar como por el reconocimiento desde los márgenes de lo rural, canalizando demandas y preocupaciones estudiantiles.

Assessment of the wind power generation uncertainty on the steady-state operation of electric power systems
Authors: Sandoval Pérez Uriel Fernando , Fuerte Esquivel Claudio Ruben
Published: February 2022

Nowadays, the large-scale integration of wind energy conversion systems in transmission networks is one of the most effective and practical options for generating electricity from renewable sources. However, the increase in wind energy penetration causes the operation of electrical power systems to become more dependent and vulnerable to variations in wind speed. Within this context, it is necessary to perform probabilistic power flow (PPF) studies to maintain system integrity in the face of stochastic wind power generation. This paper describes and implements a power flow method that considers the uncertainties that arise from wind generation behavior. This PPF approach, based on a point estimation technique, is validated against thousands of Monte Carlo simulations.

Published: February 2022

In the article, the chemical stability of celsian ceramics at different firing temperatures was investigated and the structural-phase features of the obtained samples before and after interaction with alkaline and acid media were studied.

The technology of obtaining test samples was two-stage. The first stage was the synthesis of the celsian phase in a muffle furnace at a temperature of 1200 °C with a holding time of 2 hours and subsequent cooling together with the furnace. The second stage took place in a silitic furnace at temperatures of 1300, 1350 and 1400 °C with a set rate of 15 deg/min and holding at a maximum temperature of 4 hours. The chemical resistance of celsian ceramics was determined in relation to 20 % solutions of HCl and NaOH. The phase composition of the test samples was determined using the method of X-ray phase analysis (X-ray diffraction) using a DRON-3M diffractometer. The studies of the experimental samples microstructure and the surface morphology of their faults were carried out by the direct method of scanning electron microscopy using a scanning electron microscope PhenomPro.

It was found that in relation to the 20 % solution of NaOH celsian ceramics was insoluble and has a value of alkali resistance in the range of 99.47—99.67 %. The study of microstructure and phase composition of celsian ceramics samples after treatment with 20 % NaOH solution showed that in all studied samples there was only a crystalline phase of celsian, the corrosion process didn’t occur. In relation to the 20 % HCl solution, the process of celsian ceramics corrosion was observed with the complete chemical interaction of the celsian phase with hydrochloric acid and the subsequent formation of the barium chloride dihydrate phase.

Published: February 2022

The article analyzes the advantages and disadvantages of large-format ultra-thin ceramic granite slabs, shows the need and identifies ways to increase their strength. The composition of the ceramic matrix has been developed, provides the maximum level of sintering (W ≤ 0.5 %) in accordance with the requirements for ceramic plates of class ВІа, and the choice of the reinforcing filler has also been substantiated. It has been experimentally established that mullite-silica fibers have a positive effect on the physical and mechanical properties of the slabs, which makes it possible to reduce their thickness by three times, and therefore significantly reduce the weight of products. The fractional composition of the grinding products of mullitesilica fibers was determined depending on the grinding conditions, and the influence of the quantitative and qualitative characteristics of the reinforcing filler on the main properties that determine the quality of ceramic granite slabs was investigated. The conditions for the formation of densely sintered composite materials with a complex of high-performance properties have been determined. It was shown the possibility of increasing the samples bending strength up to 57 MPa by introducing 4 wt. % of finely dispersed mullitesilica fibers, most of which (~ 60 %) have a length up to 45 microns, which is achieved by 3 min grinding in a planetary mill at a speed of 300 rpm. The structural-phase features of the samples obtained under the high-speed firing conditions, which consist in the increased amount of the mullite phase formation in the presence of mullite-silica fibers, have been established. The latter not only reinforce the ceramic matrix, but also act as a precursor of new mullite formations, the crystals of which, in the presence of a melt, acquire an isometric shape and contribute to an increase in the products strength. The research results indicate the promising obtain large-format ultra-thin ceramic granite slabs using composite materials technology. The combination of excellent technical qualities, large dimensions, and reduced slabs thickness opens up the new possibilities for using composite ceramic granite in design of furniture and large rooms due to the possibility of creating a continuous seamless coating and a significant reduction in the products weight.

Published: February 2022

The article presents the studies results of magnetic-pulse pressing in relation to ceramic masses based on non-sintering loam with the addition of coal flotation waste and the possibility of its use as a method for intensifying structural and phase transformations during sintering of masses was shown. A comparative characteristic of the properties of ceramic materials obtained by the usual mode of heat treatment at a temperature of 950 °C by the method of magnetic-pulse pressing with different amplitude of impact force was presented. To determine the operating parameters influence of the magnetic-pulse press on the samples properties, their pressing was carried out with a controlled voltage at a constant capacitance of the capacitor. It was found that an increase in the amplitude of the impact force from 6 kN to 15 kN leads to a decrease in the water absorption of ceramic samples from 21.6 % to 12.1—15.0 %, open porosity from 34.6 % to 21.6—27.0 %, and a threefold increase in mechanical strength. In comparison with samples of static pressing, the cold crushing strength of dynamic pressing samples increases by 34 % (from 8.7 MPa to 13.1 MPa) even with the minimum amplitude of the impact force (6 kN). The macrostructure, phase composition and properties of dynamic pressing ceramic samples obtained at firing temperatures of 920 °C and 950 °C have been studied. It was found that the samples had practically the same level of technical characteristics (water absorption, density, and strength) and they were similar in structure and phase composition (quartz, microcline, ɑ-hematite, X-ray amorphous phase). The possibility of obtaining ceramic materials with a completed process of the structural-phase composition formation and properties at a lower firing temperature has been established.

On the basis of carried out studies, the possibility of using dynamic pressing as a method for intensifying structural-phase transformations during sintering of ceramic materials has been shown, which can serve as a reserve for energy saving when obtaining ordinary structural building ceramics of increased grade.

On the High Dimensional RSA Algorithm—A Public Key Cryptosystem Based on Lattice and Algebraic Number Theory
Authors: Zhiyong Zheng , fengxia liu
Published: February 2022

 The most known of public key cryptosystem was introduced in 1978 by Rivest, Shamir and Adleman [19] and now called the RSA public key cryptosystem in their honor. Later, a few authors gave a simply extension of RSA over algebraic numbers field( see [20]- [22]), but they require that the ring of algebraic integers is Euclidean ring, this requirement is much more stronger than the class number one condition. In this paper, we introduce a high dimensional form of RSA by making use of the ring of algebraic integers of an algebraic number field and the lattice theory. We give an attainable algorithm (see Algorithm I below) of which is significant both from the theoretical and practical point of view. Our main purpose in this paper is to show that the high dimensional RSA is a lattice based on public key cryptosystem indeed, of which would be considered as a new number in the family of post-quantum cryptography(see [17] and [18]). On the other hand, we give a matrix expression for any algebraic number fields (see Theorem 2.7 below), which is a new result even in the sense of classical algebraic number theory.

Efforts to improve the quality of education in Indonesia are carried out in various ways. One of them is by changing conventional education into technology-based education. The strategy in improving the quality of education is done by applying information technology in learning in schools. With this application, it will support the learning process that produces skilled students in anticipating the progress of science and technology. The purpose of this study was to find out how teachers and the application of information technology in improving the quality of learning. The research used is a qualitative approach from the results of observations, interviews and documentation. The subject used in this study is the MI Miftahul Ulum Bago Pasirian institution. Based on research conducted by researchers, the roles played by teachers in learning are: first, encouraging students to interact with learning resources or learning media; second, encouraging students to have discussions with their friends; third, asking questions from the teacher to students or students to their friends; fourth, monitoring students' perceptions and thinking processes; fifth, monitor and observe the learning outcomes; sixth, as a mediator in student discussions; and seventh, evaluating to always improve student learning outcomes. This role is accompanied by implementing information technology systems in learning
Should Shareholders Be Rewarded for Loyalty? European Experiments on the Wedge Between Tenured Voting and Takeover Law
Authors: Mosca Chiara
Published: February 2022

Corporate law reveals its democratic background when it comes to the general meetings of shareholders, finding, on both sides of the Atlantic, its most tangible expression in the “one share, one vote” principle. While, in the political landscape, the “one person, one vote” standard is absolute dogma and weighting votes according to people’s preferences and interests has never proved feasible, in the corporate scenario the one share, one vote principle is constantly challenged by the incentives of companies and their shareholders to shape corporate rights according to specific needs. In this respect, some legislators (specifically in France and Italy) have provided mechanisms that allow more loyal shareholders to increase their voting power. Tenured voting (or time-phased voting rights) should be analyzed in light of the modern corporate governance debate, which calls for a stronger role for long-term investors. However, the other side of the coin should be considered: the increase in voting rights broadens the range of control-enhancing mechanisms, although specific sunset clauses (whether provided for by law or voluntarily opted in by companies) may restore the one share, one vote rule. The analysis suggests that the mechanism based on tenured voting is more transparent and potentially less stable than other common control-enhancing mechanisms and deserves to be considered in the debate. At the EU level, the possibility left to the Member States of weighting shareholders’ voting power according to their long-term interests, leads to legislative fragmentation across Europe. Specifically, in Italy, the adoption of tenured voting coupled with a tradition of ownership concentration sharply empowers controlling shareholders. At the same time, European takeover regulation plays an exogenous role in indirectly selecting the companies that adopt time-phased voting rights. The final result is completely mistrusted, as tenured voting rights disappoint their expectations and are rarely used to meet a true need of long termism. The paper describes the paradox that emerges when tenured voting rights interact with the core principles of the EU financial market law system, and it offers various ways to alleviate this difficult coexistence.
Deruglatory Riders Redux
Authors: McGarity Thomas
Published: February 2022

Soon after the 2010 elections placed the Republican Party in control of the House of Representatives, the House took up a number of deregulatory bills. Recognizing that deregulatory legislation had little chance of passing the Senate, which remained under the control of the Democratic Party, or of being signed by President Obama, the House leadership reprised a strategy adopted by the Republican leaders during the 104th Congress in the 1990s. The deregulatory provisions were attached as riders to much-needed legislation in an attempt to force the Senate and the President to accept the deregulatory riders to avoid the adverse consequences offailing to pass the more important bills. This Article examines the deregulatory riders of the 104th Congress and the experience to date with deregulatory riders during the 112th Congress. Although riders are not inherently good or evil, the Article concludes that riders, like the deregulatory riders examined here, that advance narrow special interests over the general public welfare represent bad public policy. The Article examines several methods for discouraging deregulatory riders, but concludes that none of them are likely to be implemented until the public signals its strong disapproval of deregulatory riders.
Midnight Rules: A Reform Agenda
Authors: Beermann Jack
Published: February 2022

There is a documented increase in the volume of regulatory activity during the last ninety days of presidential administrations when the President is a lame duck, having either been defeated in a bid for re-election or being at the end of the second term in office. This includes an increase in the number of final rules issued as compared to other periods. The phenomenon of late-term regulatory activity has been called “midnight regulation,” based on a comparison to the Cinderella story in which the magic wears off at the stroke of midnight. This Article looks closely at one species of midnight regulation— namely, midnight rules. This Article defines midnight rules as agency rules promulgated in the last ninety days of an administration. This Article focuses on legislative midnight rules (normally issued under the notice and comment procedures of the Administrative Procedure Act (APA)), because they are the most visible and often the most controversial actions taken in the final days of administrations and because they are usually the most difficult to alter or revoke among the various midnight actions taken by outgoing administrations. However, because late-term activity goes beyond legislative rulemaking, this report also discusses, to a lesser extent, other phenomena such as the issuance of non-legislative rules including interpretative rules and policy statements; non-rule regulatory documents, such as guidance documents and executive orders; and the use of other presidential powers, such as the pardon power and the ability to entrench political appointees into protected employment positions in the new administration. This Article documents the existence of the midnight rules phenomenon both quantitatively and qualitatively, using numerical measures of the volume of rules and qualitative analysis of some rules as illustrations. The Article reviews various explanations for the existence of the phenomenon, ranging from the simple human tendency to work to deadline, to more complicated political factors that may affect the timing of rules. The Article also reports on interviews of officials involved in rulemaking to inform the analysis of the causes and effects of the midnight rulemaking phenomenon. This Article also addresses midnight rulemaking from a policy perspective, asking whether there are reasons to be concerned about the phenomenon. Midnight rulemaking and midnight regulation generally have been strongly condemned by commentators and media from across the political spectrum. There are at least two possible sets of concerns regarding the increase in rulemaking at the end of an administration: first, midnight rules may be of lower quality than rules issued at other times during administrations, and second, midnight rulemaking may involve undesirable political consequences, mainly the unwarranted extension of an outgoing administration’s agenda into the successor’s term. It may be very difficult to arrive at firm conclusions on either of these potential objections to midnight rulemaking, but this Article will attempt to do so from various perspectives.
