Grasa y chile: ingredientes cotidianos en las mesas mexicanas
Authors: Delgado Jacobo Dolores Patricia
Published: February 2023

La alimentación “a distancia” en pandemia ha forzado a la población a cambiar su estilo de vida incluyendo el alimentario. Si bien el estilo alimentario en México a lo largo de su historia ha tenido muchos cambios desde la época nómada hasta la occidentalización pasando por la prehispánica y la colonial. En ese recorrido, algunos nutrientes mexicanos han sobrevivido a los cambios como el maíz, el frijol, el chile, el jitomate y el aguacate, variando su preparación y conservación. La incorporación de la grasa animal derivada del cerdo, pollo o res ha enriquecido la preparación de alimentos “típicos” como las carnitas, las quesadillas o los tamales. En años de pandemia (2020 y 2021) su acceso se facilitó por los servicios de comida a domicilio. El presente trabajo consistió en revisar el estilo de vida alimentario en confinamiento a través de los reportes científicos, que permitieron obtener una descripción actual de los efectos de la pandemia en la alimentación de la población mexicana. Además de los efectos en la prevalencia de enfermedades crónicas no transmisibles como el sobrepeso y la obesidad.

Published: February 2023

El agua es el componente más abundante en el cuerpo humano, se distribuye por todas las células. En personas sanas la cantidad de agua total en el organismo tiene estabilidad debido a mecanismos fisiológicos, pero cuando las pérdidas de agua superan a los ingresos sobreviene la deshidratación, la cual produce efectos negativos en la salud de los individuos. Tanto la cantidad de líquido que se consume como la que el organismo necesita varían dependiendo de la dieta, disponibilidad, incluso de la educación, condiciones ambientales, edad, metabolismo, actividad física y condición de salud. El objetivo de este artículo es realizar una revisión de algunas bebidas disponibles, tanto de sus componentes como de los aportes que tienen al organismo y algunas recomendaciones respecto al consumo de agua, de forma general.

Abstract: Landing Gear is proved to be the most critical subsystems in aircraft. It is a crucial part in all ground operations, takeoff and landing of aeroplane. Landing gear operates as dead weight after an aircraft is in the air, burning more fuel and taking up room which can be used for other safety measures. When taking into account all the legal and safety standards, it is vital to shorten the time needed for the landing gear design and its development cycle. All aerospace sectors strive for attributes such as minimal weight and volume, great performance, and reduced life cycle costs. Our objective was to create a landing gear with the least amount of weight and volume while maintaining maximum structural integrity. To achieve this goal, we designed landing gear links using generative design. In addition to this, we also studied different parameters considered for landing gear design.

Overall risk dominates the medium rating, which is 28 risks and the high risk consists of 20 risks. The negative risk response is dominated by mitigate, which is 33 risks.
Reengineering of logistics processes as the basis for the establishment and operation of logistics centres in the construction industry
Authors: Sborshikov Sergey B. , Lazareva Natalia V.
Published: February 2023

Introduction. Digital and technological transformations of the national economy and the investment and construction sector as its integral part determine the need for the qualitative transformation of technical solutions in respect of both managerial and technological processes, referred to as reengineering in the present-day theory and practice. In turn, not only the main production activity is subject to such transformations, but also supplementary activities, including logistic support. In this regard, there is a contradiction between the transformed research and technology fundamentals of construction processes and traditional forms, as well as practical implementation patterns. In the field of logistics, this problem can be solved by logistics centres that are closely related to production and engineering structures. The purpose of the study is to establish a scientific rationale for the logistics efficiency intensification and improvement using logistics centres amid digital and technological transformation of the construction industry. This mission determines the following research tasks: establishing the nature of changes in flow management patterns applied to material and technical resources in the construction industry; proposing new configurations of these flows using logistics centres, determine the their position in the overall corporate structure. It is for the first time that this problem is formulated this way, which indicates its originality. The study is focused on logistics processes and their reengineering. Logistics centres are chosen as the subject of the study. Its practical value is a combination of the reengineering theory and new corporate structures such as production, engineering and logistics centres focused on intensifying processes of construction and enhancing the quality of the output.

Materials and methods. The theory of logistics of regulatory impacts is used as the main methodological approach. Structural and functional analysis is used to confirm certain assumptions. Earlier research, as well as publications of local and foreign researchers, was used by the authors as the source data.

Results. An organizational chart is proposed for the establishment and operation of a logistics centre in the construction industry; principal diagrams are developed for the flows of materials and resources; they are used to demonstrate interaction between a construction facility and a logistics centre.

Conclusions. A logistics centre is a promising tool for modernizing and intensifying the logistic support of construction processes; it unlocks a high potential for the economic efficiency and competitiveness, cuts hidden losses and is primarily determined by lower downtime and a smaller amount of in-house and external defective construction products.
Development of a methodology underlying a deterministic model of construction work arrangements on the basis of the concept of an organizational and technological platform for construction
Authors: Lapidus Azariy A. , Motylev Roman V. , Sokolnikov Vladimir V.
Published: February 2023

Introduction. Presently, intensively developing digital technologies can be contributed to theoretical models, engineering designs, as well as construction implementation methods. The article addresses the justification of a methodology underlying a deterministic model of construction work arrangements, designed to eliminate a methodological gap between theoretical methods of research and simulation, engineering methods of design and methods of implementing solutions to problems of construction processes.

Materials and methods. Relations between the key sets of elements of construction processes were identified to justify the methodology, underlying the deterministic model of construction arrangements, using methods of the general theory of systems. Approaches to development of an organizational and technological platform in the construction industry and researches in the field of organizational and technological reliability of construction processes are also provided. Model elements are presented as a consolidated block diagram of methods, technological and administrative procedures, as well as construction process periods. The authors present a system for classifying theoretical models that are applicable to construction process research.

Results. The methodology, underlying the deterministic model of construction process arrangements, is justified by a system of linear equations, describing construction process components. Construction process components are determined by the structural block diagram of construction process arrangement methods. Parameters and variables of equations convey a unified organizational and technological construction platform, and they can serve as a constituent of the criterion of meeting scheduled deadlines in the course of evaluating the organizational and technological reliability of the construction process.

Conclusions. The methodology, underlying the deterministic model of construction process arrangements, based on the concept of an organizational and technological platform of construction processes, represents a structure of algorithms designed to coordinate decisions concerning construction processes, obtained using various methods. This coordination is implemented using sets of ratios between technological and organizational parameters of construction processes and the criterion of predicted time reserves needed for the implementation of current processes and related engineering operations, given that resources and time are still available according to the construction schedule.

Authors: Shvetsova-Shilovskaya Elizaveta A.
Published: February 2023

Introduction. The reconstruction of Orthodox monastery complexes in the Russian North faces a number of challenges arising due to a dramatic increase in the number of pilgrims and tourists, as well as the restoration of traditional and emergence of new functions performed by monasteries. The author investigates the reconstruction of the Holy Trinity Zelenetsky Monastery (“the Zelenetsky Monastery”) in the Leningrad region amid an increasing number of visitors. By now, all the main traditional functions of this monastery have been restored in some way.

Materials and methods. The authors use an integrated approach to identify the general principles that allow solving the most relevant problems of the Zelenetsky Monastery. This approach includes investigation of historical and design documents on the monastery architecture, analysis of functions performed by this monastery, analysis of restoration results, as well as the comprehensive assessment of the outcome of recommendations proposed here.

Results. We propose a number of specific recommendations aimed at improving the architectural ensemble of the Zele­netsky Monastery. These recommendations are concerned with the master plan of the Zelenetsky Monastery, as well as the buildings of its main functional groups. The recommendations, that were formulated and justified earlier, are based on four general principles dealing with the reconstruction and development of Orthodox monastery complexes in the Russian North under the present-day conditions.

Conclusions. The authors have developed recommendations for the reconstruction of the Zelenetsky Monastery. The implementation of these recommendations leads to the optimal zoning of the monastery area, preservation of its architectural ensemble and surrounding natural landscape. It also ensures the best conditions for monastery visitors and brethren.
Prediction of principal stresses from external loads in sandy soils and ash-slag mixtures
Authors: Lunev Aleksandr A.
Published: February 2023

Introduction. Earlier studies indicate that a change in the structure of any material triggers a change in its stress state development pattern. It is obvious that when the type of soil, humidity and density of the massif change, its mechanical characteristics and the stress state change respectively. Therefore, to study the influence of genesis on the stress state, the authors analyzed dependences, proposed for predicting maximum principal stresses arising in soil massifs subjected to external loading by a round plate. The analysis shows that taking into account the features of the stress state development in the proposed models is connected with mechanical characteristics of soils. However, previous studies show that these dependencies are not universal.

Materials and methods. To verify the adequacy of the solutions, experimental studies were conducted to determine pressures arising in sandy soils, ash-slag mixtures subjected to external loading. Physical and mechanical characteristics of the materials in the state under study were determined (such as the angle of internal friction, specific adhesion, modulus of deformation (elasticity)).

Results. The experiments show that the pressure attenuation intensity increases with depth along with the increasing density of massifs, regardless of the genesis, and attenuation is more intense in ash-slag mixtures. The authors have found that the development of stresses in soils of various genesis can be described by applying solutions based on the mechanics of the granular medium (Kandaurov’s solution) and continuum mechanics (this solution was proposed by Frohlich).

Conclusions. The results of the work demonstrate the need to employ different approaches to predicting the stress state in soils of various genesis. Correlations between mechanical characteristics of soils (such as the friction angle and the modulus of elasticity) and parameters of the distributing medium indicate the need to study clay and other types of man-made soils.
Calculation of the level of energy efficient heat protection
Authors: Frolova Anastasiya A. , Lukhmenev Pavel I.
Published: February 2023

Introduction. The choice of the level of heat protection of buildings should be based on the economic performance of buildings, taking into account the cost of maintaining the pre-set thermal microclimate on the premises. Hence, it is necessary to initially determine the amount of energy consumed by the heating, atmospheric and mechanical cooling of buildings. Towards this end, buildings that are different in size and have different numbers of storeys are studied. These buildings are located in various Russian regions featuring different periods of heating and solar radiation intensity. They are Moscow (central Russia), Astrakhan (southern region) and Vorkuta (northern region).

Materials and methods. The problem is solved computationally; the authors use buildings of different geometry that are located in Moscow, Astrakhan and Vorkuta. Various levels of heat protection of external walls and coatings, as well as different values of heat gain are considered. For all options, annual energy costs are calculated using primary fuel costs. Simulation and comparison were chosen as the main research methods.

Results. The results are presented in the form of tables of annual primary energy consumption required to maintain the pre-set thermal parameters for various building options featuring different levels of heat protection and heat gain.

Conclusions. According to the research findings, the highest level of heat protection is the best heat protection option from the standpoint of energy consumption in the cities under consideration (Moscow, Astrakhan and Vorkuta). Year-round heat gains reduce the load on the heating system during cold seasons; however, they have a negative impact du­ring warm seasons and transition periods due to the additional load on the air conditioning system. According to the calculation results, if the building heat density equals or exceeds 40 W/m2, some rooms may need cooling during cold seasons.

Response to Cummins: The OHRC Right to Read Report will Move Ontario into the 21st Century
Authors: Klein Perry
Published: February 2023

In the April 2022 issue of the Journal of Teaching and Learning, Dr. Jim Cummins responded to the Ontario Human Rights Commission (2022a, 2022b) report on the Right to Read: Public Inquiry into Human Rights Issues Affecting Students with Reading Disabilities. He expressed several views on literacy education that are moderate and consistent with research. However, his very critical appraisal of the report is misdirected. The first section of the present article documents several recommendations and positions that Cummins attributes to the report but that it does not actually contain. The second section identifies five ways in which this report will bring Ontario’s special education policy into the 21st century, which Cummins has missed. The Right to Read report provides a paradigm for special education that Ontario should now apply to additional domains such as mathematics and social and emotional learning.
Quantifying EPR: the resource theory of nonclassicality of common-cause assemblages
Authors: Zjawin Beata , Schmid David , Hoban Matty J. , Sainz Ana Belén
Published: February 2023

Einstein-Podolsky-Rosen (EPR) steering is often (implicitly or explicitly) taken to be evidence for spooky action-at-a-distance. An alternative perspective on steering is that Alice has no causal influence on the physical state of Bob's system; rather, Alice merely updates her knowledge of the state of Bob's system by performing a measurement on a system correlated with his. In this work, we elaborate on this perspective (from which the very term 'steering' is seen to be inappropriate), and we are led to a resource-theoretic treatment of correlations in EPR scenarios. For both bipartite and multipartite scenarios, we develop the resulting resource theory, wherein the free operations are local operations and shared randomness (LOSR). We show that resource conversion under free operations in this paradigm can be evaluated with a single instance of a semidefinite program, making the problem numerically tractable. Moreover, we find that the structure of the pre-order of resources features interesting properties, such as infinite families of incomparable resources. In showing this, we derive new EPR resource monotones. We also discuss advantages of our approach over a pre-existing proposal for a resource theory of 'steering', and discuss how our approach sheds light on basic questions, such as which multipartite assemblages are classically explainable.

In this paper, the model of information exchange system was promoted.
With Miner’s linear cumulative damage theory and life prediction method,
the fatigue strength of Hinge Sleeve of Cubic was calculated and
simulated by ANSYS. Firstly, the model of Hinge Sleeve of Cubic is
established, and the stress of the Hinge Sleeve of Cubic is calculated.
Then the fatigue strength of Hinge Sleeve of Cubic was calculated with
Miner’s linear cumulative damage theory and life prediction method. In
ANSYS, combined with static analysis, topology optimization and Fatigue
function corresponding data, the information exchange system for life
optimization design of Hinge Sleeve of Cubic was created. According to
the required load conditions, the material foundation data and boundary
constraints are set, and the stress correction curve is loaded for
fatigue calculation. With the results of fatigue calculation, the
simulation verification is carried out again. The final model of
mass-reduction design is obtained through repeated optimization
verification by combining ANSYS data with topology optimization.
Compared with traditional theoretical calculation methods, the optimized
Hinge Sleeve of Cubic was obtained by the optimization method based on
information exchange model proposed, it has better computing

Published: February 2023

The aim of this study was to use micro-computed tomography (CT) analysis
to evaluate the efficiency of the XP-endo finisher (XPF) and passive
ultrasonic irrigation (PUI), alone or in combination, in reducing
accumulated hard tissue debris (AHTD) in the mesial canals of mandibular
molars. The teeth were micro-CT scanned preoperatively (S1), after
instrumentation (S2), after final irrigation (S3), and after a
supplementary activation (S4). The mesial roots were prepared with BT
Race sequence to apical size 35/.04 and divided in two groups according
to the final irrigation method and the sequential supplementary
activation (PUI + XPF group, n = 12; XPF + PUI group, n = 12). The data
of percentages of reduction of AHDT after the first irrigation and
supplementary activation were statistically analyzed (RM ANOVA). In the
apical third, XPF reduced the percentage of remaining AHTD (66.49%)
more significantly than the PUI (35.27%) (P < 0.05). The
supplementary activation promoted a statistically significant reduction
of AHTD in the apical-thirds of both groups (P < 0.05). In the
XPF group the middle (90.85%) and apical (80.02%) thirds were affected
by the supplementary activation with ultrasonic irrigation (P
< 0.05). Both PUI and XPF were efficient in the reduction of
AHTD, but in the apical third XPF was more effective. The supplementary
activation with both systems reduced the AHTD significantly. The order
of application of irrigation systems influences the reduction of
accumulated AHTD and the use of XPF followed by PUI proved to be more
efficient.
Reformas educativas para una crisis. Acerca de la educación del carácter en Platón y Aristóteles
Authors:   Uni­versidad Complutense de Madrid, Hernández de la Fuente David
Published: February 2023

This work considers the current crisis in the Western world, caused by the pandemic, war, energy supply issues, and other related disturbances, and its potential impact on current educational models, which are being reformed in various countries and attempts to relate it with historical precedents from classical antiquity that were a reaction to crises of ancient democracy through more or less utopian proposals for the reform of the traditional educational system put forward by two great thinkers: Plato and Aristotle. Our aim is to try to summarize the importance for these two thinkers of the education of individual character in the pursuit of the common goods of various political communities by uniting the wills of the citizens. The methodology used is rereading the fundamental passages of the classical sources on character and education in the young, comparing them with the points of view of most of the research, summarized in the assessments of the great manuals of the history of education. Despite being a well-known theme, it is worthwhile returning to these passages for an updated reflection in our contemporary world. Thus, it is apparent that, in spite of the obvious divergences between the philosophical systems of Plato and Aristotle, there is a curious similarity in the case of character education as the key to solve the problems posed for a society in times of crisis.

Published: February 2023

In recent years, several initiatives have attempted to integrate character education in universities. However, it is difficult at the university level to find initiatives aimed at generating communities in which their climate or culture contribute to character development, a relatively common approach at the school level in the character education movement. University residential centers may be an ideal setting for generating such communities. However, studies, guides, or programs along these lines are scarce or non-existent. A case worthy of study is that of Colegios Mayores, university residential communities in Spain with a centuries-old tradition that aim to contribute to the integral development of students. However, the literature on the educational dimension of this institution is also scarce and outdated. Contributing to outline its educational dimension, this study reports the results of a survey of directors of Colegios Mayores. The aims of this study are to: 1) explore whether the community of Colegios Mayores agrees in considering six practices as characteristic of this institution; 2) explore the level of implementation of each one of them; and 3) explore if the way in which the community members are involved in these practices responds to the social learning model of Communities of Practice proposed by Etienne Wenger. The questionnaire was answered by 19 directors, representing 15.2% of the population (N=125). Based on the results, it is reasonable to affirm that most directors of Colegios Mayores: 1) consider that the six practices proposed are characteristic of this institution; 2) already implement these practices in their centers; and 3) consider that the Communities of Practice model reflects the way in which the collegial community engages in these practices.

Global challenges require a transition from the existing linear economic model to models that will consider nature as a life support system for the development on the way to social well-being in the frame of the ecological economics paradigm. The article presents results of the development of formalizing the sustainable development monitoring using the concept of energy flows in open non-equilibrium stable socio-economic complex systems in the frame of ecological economics approach. The authors calculated and used a new system of universal parameters of sustainable development: total consumption of energy resources, total production, power losses and impact on environment, technological excellence. Level of human life was defined as a function of total production, environment changing, population changing and technological efficiency level. In context of considering approach, universal parameters were calculated using the data of Eurostat during the period from 1990 to 2019 and using statistical analyses methods. The main results: definition of the type and structure of the final consumption models (theoretical trends) on energy resources time series; allocation of stationary and non-stationary components in time series; calculation and primary interpretation of the system of basic parameters of a sustainable for the countries of Europe - Latvia, Lithuania, Estonia, Slovakia and Bulgaria. The countries as objects of research were selected in accordance with the following parameters: the population of each state is not more than 10 million and membership of the EU since 2004. The results of the research have indicated that there are several challenges in the analysed countries with several similarities, and there are possibilities to share and use the experience of energy resources flows approach for data analysis.

Published: February 2023

Metasurface can adjust the polarization, amplitude, phase, polarization mode, and propagation mode of electromagnetic waves flexibly and efficiently. Based on Pancharatnam–Berry phase theory, an all-medium geometric phase element structure was proposed to construct a transmission-coded metasurface metalens. In the mid-infrared band, a phase change material (GST) is used to regulate the unit structure in order to achieve the tunability of lens focus. In order to prove that the designed hyperlens has a good focusing effect, we numerically simulate the focusing electromagnetic field distribution characteristics, and the results show that the designed geometric phase hyperlens has a good focusing effect. Using the crystal and amorphous states of phase change materials, we can dynamically control the focus of the superlens.

Objective: The objective of this in vitro study was to evaluate the volumetric wear of three CAD/CAM (computer-aided design/computer-aided manufacturing) ceramic materials.

Materials and Methods: The materials evaluated were CEREC Blocs (Dentsply Sirona), Initial LRF (GC) and Amber Mill (HASS Corp). All the samples (n=30) were subjected to simulated brushing (100,000 cycles). The wear was assessed by superimposing pre- and post-brushing scans obtained with an intraoral optical scanner (CEREC Primescan; Dentsply Sirona, Germany), which was then imported into the OraCheck 5.0 software (Dentsply Sirona, Germany).

Results: The CAD/CAM ceramic materials tested showed no statistically significant differences in terms of the average volumetric wear (p-= 0.455).

Conclusion: Therefore, it can be concluded that the ceramic materials have a good behavior under simulated brushing, without significant volumetric alterations.
The Effects of the Economic Crisis on Greek Society and the Youth Unemployment: Self-Perception and Expectations of the Young Neets
Authors: Politou Angeliki , Nikolakaki Maria
Published: February 2023

The economic crisis of the previous decade left its mark on Greek society through its multidimensional economic and social effects. However, the most basic issue in Greek society was the rapid increase in unemployment and in particular youth unemployment, culminating in the emergence of the Neets phenomenon, the population of young people who are out of employment, education or training. Young people were affected the most during the economic crisis, shaping their expectations and self-perception against the risk of unemployment, poverty and social exclusion. In this context we explore expectations and self-perception of unemployed young people in debt-ridden Greece based on nationwide quantitative research conducted through questionnaires. The sample was 360 young persons of 15 – 25 years old who are out of employment, education or training (Neets). According to the results, the majority of young people maintain their optimism for their future, continuing to make plans, having high job motivations and desiring full employment, as well as the continuation of their training in programs which, however, are linked to the labor market. The reduction of their expectations and their participation in brain drain is done mainly for livelihood reasons and in the absence of other alternatives. The decrease in their optimism is mainly based on the fear of long-term unemployment, the low level of income, but also on the inability to utilize their high qualifications, while despite their optimism, young people show increased levels of anxiety and depression, due to the difficulties that they face. The capture of these expectations and self-perceptions is critical in the effort to develop appropriate and effective social barriers for reintegrating young people into work and social life and avoiding social exclusion. This is an issue of social vulnerability as reflected in modern sociological theory but also in the active practices of applied social and educational policy. This research can be framed also by the principles of critical pedagogy as young people could reach for critical consciousness before they radically change the material conditions of their society.

This study aims to understand the crises experienced by family-owned accommodation businesses in small island contexts and how resilience is built alongside the development of their dynamic capabilities (sensing, seizing, and transforming) as they navigate through crises. The study uses a qualitative method and focuses on the experiences of tourism businesses operating in the islands of Boracay, Negros, and Siargao, which are among the top island destinations in the Philippines. Semi-structured interviews with 18 participants were conducted through 1-hour online video calls, phone calls, and written 2 interviews. Crises that affect tourism businesses are mostly due to external factors. Small islands are at high risk of natural hazards, but businesses do not consider typhoons and earthquakes as crises per se since they frequently experience these hazards. Family businesses have distinct strategies, such as knowledge transfer, maintenance of stable financial resources, infrastructure development, employee training, better marketing strategies, and a focus on sustainability to enhance their dynamic capabilities and build their resilience, thus making them more adaptive to future crises. However, government support for the local tourism industry is still needed to ensure a sustainable tourism industry. Dynamic capabilities and resilience are often linked with each other yet there is limited knowledge on how resilience is built specifically in the context of family-owned businesses in small island context. This study addresses this gap in the literature by using dynamic capabilities as a framework to understand resilience development. Resilience and dynamic capabilities are then adaptive strategies in crisis management.
