Published: June 2024

Background:

Ultra-low-field magnetic resonance imaging (ULF-MRI) has emerged as an alternative with several portable clinical applications. This review aims to comprehensively explore its applications, potential limitations, technological advancements, and expert recommendations.

Methods:

A review of the literature was conducted across medical databases to identify relevant studies. Articles on clinical usage of ULF-MRI were included, and data regarding applications, limitations, and advancements were extracted. A total of 25 articles were included for qualitative analysis.

Results:

The review reveals ULF-MRI efficacy in intensive care settings and intraoperatively. Technological strides are evident through innovative reconstruction techniques and integration with machine learning approaches. Additional advantages include features such as portability, cost-effectiveness, reduced power requirements, and improved patient comfort. However, alongside these strengths, certain limitations of ULF-MRI were identified, including low signal-to-noise ratio, limited resolution and length of scanning sequences, as well as variety and absence of regulatory-approved contrast-enhanced imaging. Recommendations from experts emphasize optimizing imaging quality, including addressing signal-to-noise ratio (SNR) and resolution, decreasing the length of scan time, and expanding point-of-care magnetic resonance imaging availability.

Conclusion:

This review summarizes the potential of ULF-MRI. The technology’s adaptability in intensive care unit settings and its diverse clinical and surgical applications, while accounting for SNR and resolution limitations, highlight its significance, especially in resource-limited settings. Technological advancements, alongside expert recommendations, pave the way for refining and expanding ULF-MRI’s utility. However, adequate training is crucial for widespread utilization.

Authors: Torres-Urquia Annelisse , Jesus Orlando De
Published: June 2024

Background:

Head and spine injuries sustained following golf cart accidents have been rarely analyzed. This study aimed to describe a series of patients sustaining golf cart injuries requiring neurosurgical management for head or spine injuries.

Methods:

The University of Puerto Rico Neurosurgery database was used to retrospectively identify and investigate patients who sustained a golf cart-related injury requiring a neurosurgical evaluation during 15 years.

Results:

The analysis identified 25 patients with golf cart-related injuries requiring neurosurgical management with a median age of 16 (interquartile range 13–34). Seventeen patients (68%) were female. The primary mechanism of injury was ejection from the cart in 84% of the patients (n = 21). The most frequent head injury was a skull fracture in 80% of patients (n = 20). Intracranial hemorrhage was present in 76% of patients (n = 19), with brain contusions (n = 16, 64%) being the most common. Eighteen patients (72%) were admitted for surgery or neurological monitoring. The median hospital length of stay among hospitalized patients was 5.5 days. Ten patients (40%) were admitted to the intensive care unit (ICU) with a median stay of 8.5 days. Four patients (16%) required surgery for their injuries. At discharge, 80% of patients (n = 20) had a good outcome.

Conclusion:

This study showed that children and adolescents are at high risk for golf cart-related neurosurgical injuries. This form of transportation can produce considerable neurological injuries, the primary mechanism of injury being ejection from the cart. Approximately three-quarters of the patients need hospital admission, with half requiring an ICU stay.

Correlation between emotional acceptance of parents and independence level of adolescents
Authors: Kozyreva V. V. , Pham V.A.T.
Published: June 2024

The article considers the formation of independence in adolescents under the influence of emotional acceptance from parents in Vietnam and Russia. Parental emotional acceptance helps teenagers gain self-confidence and avoid difficulties when they make decisions and solve problems, thereby developing independence in thinking and behaviour. Using the methodologies “Behaviour of parents and the attitude of adolescents to them” by E. Shafer and “Diagnostics of students’ independence” by L.A. Sergienko, the authors analyse the correlation between emotional acceptance from influential parents and the level of a teenager’ autonomy. In addition, the influence of fathers and mothers on the independence of adolescents is different. The results show that emotional acceptance from both parents helps teenagers develop autunomy better than emotional acceptance from just one person. Besides, the level of emotional support is higher among Russian parents than among Vietnamese ones, and this leads to the fact that Russian teenagers are more independent than Vietnamese ones. Emotional acceptance from parents plays an important role in the development of autonomy in children, therefore parents need to create healthy relationships with them.
Identification of characteristics of Russian students’ professional identity in the humanitarian, technical, and economic areas of training
Authors: Shcherbakova O. I. , Osipov V. P.
Published: June 2024

The purpose of this research work is to identify the features of the Russian students’ professional identity who study in humanitarian, technical, and economic areas of professional training. The theoretical analysis of scientific works, within the framework of which the problem of the Russian students’ professional identity is considered, has allowed us to conclude that most of them are static and isolated, and it largely affects the content of the results. An empirical study of the statuses of 245 students’ professional identity from the Plekhanov Russian University of Economics, based on the methodology of J.Е. Marcia, has provided an opportunity to use tools of descriptive and analytical statistics. Due to the frequency analysis of the results of the empirical study, predominance of the state of achieved identity in the overall structure of respondents has been revealed. However, in the course of a more detailed intergroup examination, through the Pearson’ chi-square test, it has been proven that along with the transition from “man – sign” specialties to “man – man” specialties, the number of students with the status of the achieved professional identity decreases. Meanwhile, the number of students who have moratorium of professional identity increases. The scientific novelty of this study lies in a comparative approach to the study of professional identity of students from higher educational institutions.

Authors: Akopyan A. R. , Vorontsova Yu. V. , Krysov V. V.
Published: June 2024

In the modern world, cryptocurrencies are widely used in various economic sectors. One of the advantages of applying this type of currency is the ability to conduct fast and secure financial transactions without the involvement of intermediaries. Cryptocurrency can become an incentive for the development of new business models and creation of new opportunities for small and medium entrepreneurs. The purpose of the study is to determine the potential of applying cryptocurrencies in creative industries as well as possibility of using their advantages. Almost everyone in society is a user and potential creator of intellectual activity. Its protection through a system of national and international rules called intellectual property rights is necessary to ensure financing of innovations and creativity, which, in turn, leads to economic, cultural and social progress. Intellectual property protection also contributes to the production and dissemination of knowledge and a wide range of high-quality goods and services. Copyright is the main method of prevention of piracy and theft of intellectual property. Studying the prospects of using cryptocurrency in production in creative industries is necessary to make its formation as an important tool in this area possible.

Authors: Asra Ridho , Malmakova Aigul , Jones Alan
Published: June 2024

The tractable preparation of phase-I drug metabolites is a critical step to understand the first-pass behaviour of novel chemical entities in drug discovery. In this study we have developed a structure electroactivity relationship (SeAR) informed electrochemical reaction of the parent 2-chlorophenothiazine and anti-psychotic, chlorpromazine. The ability to dial-in under current controlled conditions the formation of S-oxide and novel S,S-dioxide metabolites has been achieved for the first time on a multimilligram scale using a direct batch electrode platform. A potential rationale for the electrochemical formation of these metabolites in situ is proposed using molecular docking to a cytochrome P450 enzyme.
A Bulk Phase Transformation Drives Ammonia Synthesis on Barium Hydride
Authors: Tosello Gardini Axel , Raucci Umberto , Parrinello Michele
Published: June 2024

It is believed by some that the key to a successful industrial heterogeneous catalyst is a complex dynamical behavior, in which the catalyst is more than just a provider of catalytic sites. With the help of machine learning-driven molecular dynamics simulations, we show that this is indeed the case for the thermally activated synthesis of ammonia catalysed by BaH2. This system has recently been experimentally investigated and shown to act as a highly efficient catalyst for ammonia synthesis, if and only if it is alternately exposed first to N2 and then to H2 in a chemical looping process. Our simulations reveal that when first exposed to N2, BaH2 undergoes a profound change and it is transformed into a superionic mixed compound, BaH(2-2x)(NH)x, characterized by a high mobility of both hydrides and imides. This transformation is not limited to the surface but involves the entire catalyst. When this compound is exposed to H2 in the second step of the looping process, the ammonia is readily formed and released, a process greatly facilitated by the high ionic mobility. Once all the nitrogen hydrides are hydrogenated, the system reverts to its initial state and it is ready for the next looping process.
Modelling ligand exchange in metal complexes with machine learning potentials

Published: June 2024

Metal ions are irreplaceable in many areas of chemistry, including (bio)catalysis, self-assembly and charge transfer processes. Yet, modelling their structural and dynamic properties in diverse chemical environments remains challenging for both force fields and ab initio methods. Here, we introduce a strategy to train machine learning potentials (MLPs) using MACE, an equivariant message-passing neural network, for metal-ligand complexes in explicit solvents. We explore the structure and ligand exchange dynamics of Mg2+ in water and Pd2+ in acetonitrile as two illustrative model systems. The trained potentials accurately reproduce equilibrium structures of the complexes in solution, including different coordination numbers and geometries. Furthermore, the MLPs can model structural changes between metal ions and ligands in the first coordination shell, and reproduce the free energy barriers for the corresponding ligand exchange. The strategy presented here provides a computationally efficient approach to model metal ions in solution, paving the way for modelling larger and more diverse metal complexes relevant to biomolecules and supramolecular assemblies.
Excited State Electronic Structure of Dimethyl Disulfide Involved in Photodissociation at ∼200 nm
Authors: Rishi Varun , Cole-Filipiak Neil , Ramasesha Krupa , McCaslin Laura
Published: June 2024

Dimethyl disulfide (DMDS), one of the smallest organic molecules with an S-S bond, serves as a model system for understanding photofragmentation in polypeptides and pro- teins. Prior studies of DMDS photodissociation excited at ∼266 nm and ∼248 nm have elucidated the mechanisms of S-S and C-S bond cleavage, which involve the lowest excited electronic states S1 and S2. Far less is known about the dissociation mechanisms and elec- tronic structure of relevant excited states of DMDS excited at ∼200 nm. Herein we present calculations of the electronic structure and properties of excited states S1-S6 accessed when DMDS is excited at ∼200 nm. Our analysis includes a comparison of theoretical and ex- perimental UV spectra, as well as theoretically predicted one-dimensional cuts through the singlet and triplet potential energy surfaces along the S-S and C-S bond dissociation coordinates. Finally, we present calculations of spin-orbit coupling constants at the Franck- Condon geometry to assess the likelihood of ultrafast intersystem crossing. We show that choosing an accurate yet computationally efficient electronic structure method for calcu- lating the S0-S6 potential energy surfaces along relevant dissociation coordinates is chal- lenging due to excited states with doubly excited character and/or mixed Rydberg-valence character. Our findings demonstrate that the extended multi-state complete active space second-order perturbation theory (XMS-CASPT2) balances this computational efficiency and accuracy, as it captures both the Rydberg character of states in the Franck-Condon region and multiconfigurational character toward the bond-dissociation limits. We com- pare the performance of XMS-CASPT2 to a new variant of equation of motion coupled cluster theory with single, double, and perturbative triple corrections, EOM-CCSD(T)(a)*, finding that EOM-CCSD(T)(a)* significantly improves the treatment of doubly excited states compared to EOM-CCSD, but struggles to quantitatively capture asymptotic ener- gies along bond dissociation coordinates for these states.
Leveraging our Teacher’s Experience to Improve Machine Learning: Application to pKa Prediction
Authors: Genzling Jérôme , Luo Ziling , Weiser Benjamin , Moitessier Nicolas
Published: June 2024

Machine learning (ML) is gaining momentum in chemistry for the prediction of various molecular properties, or for the generation of novel molecules with specific properties. However, these models can only be trained on relatively scarce, often low-quality data. Thus, memorization (rather than learn-ing) may result in poorly generalizable models. To address this issue, we aimed to revisit the way ML is practiced in chemistry. Using pKa prediction as an example, we present our strategy which involves imparting Chemistry knowledge to ML algorithms. We posit that teaching fundamental principles (e.g., electronegativity and inductive effect) to machines to predict properties (e.g., pKa), analogous to the way we teach students, will allow them to predict more advanced, yet related, properties. Thus, ML will leverage the chemists’ knowledge and qualitative principles to quantify and predict chemical properties.
Impact of the halogen PB radii in the estimation of protein-ligand binding energies using MM-PBSA calculations
Authors: Fortuna Andreia , Costa Paulo J.
Published: June 2024

Halogenation is a commonly used strategy in drug design, not only due to the improvement of ADME properties of the compounds but also due to the ability of halogens to engage in halogen bonds (XBs) with biological targets such as proteins. The prediction of binding free energies (\dGbind{}) is paramount in drug development, and, in this context, MM-PBSA calculations are a fast and commonly used method to achieve such a task. However, the usage of parameters to describe halogen anisotropy, such as extra-points of charge (EPs) that allow for the sampling of XBs, in MM-PBSA calculations is not common. Despite the recent development of optimized radii for halogens (r$_{opt}$), compatible with EP implementations, providing accurate hydration free energies at the PBSA level, the impact of these parameters in the calculation of binding free energies (\dGbind{}) on protein-ligand complexes was yet to be tackled. In this work, we evaluated the performance of r$_{opt}$ in the estimation of \dGbind{} values using MM-PBSA calculations for three sets of CK2 inhibitors. for which the experimental binding energies are available. We tested the performance of three EP models and standard RESP charges (i.e. when no EP is added), along with the effect of the internal dielectric constant ($\epsilon$_{\textnormal{in}}$) and sampling time. Our results indicate that, while directly using the X-ray structure does not typically lead to good results, relaxation through MM minimization, especially with $\epsilon$_{\textnormal{in}}$ = 4, leads to very decent correlations with the experimental values. Better correlations were achieved when adding configurational sampling via MD simulations, though, the Pearson coefficients varied substantially with sampling time and PBSA setup used, indicating that longer sampling times do not necessarily lead to higher correlations with experimental values. For all cases, optimized halogen radii (r$_{opt}$) leads to slight improvements whereas the description of the halogen anisotropy \textit{via} and EP considerably improved the correlations for \textbf{Set A} and \textbf{Set C}. In addition, our findings suggest that $\epsilon$_{\textnormal{in}}$ has a considerable impact on the prediction of the \dGbind{} values, with the usage of an EP being enough to account for polarizability for systems with several halogens, whereas for systems with fewer halogens, a higher $\epsilon$_{\textnormal{in}}$ might be needed. Moreover, the use of an EP allowed the sampling of XBs without impairing the sampling of hydrogen bonds (HBs). To date, this study is the first to provide a comprehensive benchmark using MM-PBSA calculations, thus giving insights into which parameters contribute to a better description of halogen bonding systems.
Guiding the rational design of biocompatible metal-organic frameworks for drug delivery
Authors: Menon Dhruv , Fairen-Jimenez David
Published: June 2024

In drug delivery, metal-organic frameworks (MOFs) have emerged as an interesting paradigm owing to their tuneable porosity, structural diversity, and ease of external surface functionalization. Compared to other drug delivery systems, state-of-the-art MOFs can encapsulate up to 50 times higher quantities of drugs per unit of mass while showing very long release times. Nevertheless, for their translation into clinical applications, concerns regarding MOF biocompatibility necessitate comprehensive mitigation. Unfortunately, experiments are resource and time-intensive, while modeling approaches fail to capture the behavior of MOFs in intricate biological systems. Herein, we report a novel computational pipeline guided by machine learning (ML) for probing the biocompatibility of MOFs. The pipeline is designed to expedite the assessment of potential MOF toxicity based on the chemical properties of their precursors. Interpretable ML models were built on a database of over 35,000 organic molecules, predicting the potential toxicity of MOF linkers with 83% accuracy. Additionally, we established a comprehensive database cataloging the toxicity of MOF metallic centers. Leveraging these, we have screened the Cambridge Structural Database (CSD) containing 86,000 non-disordered MOFs, identifying existing and future promising candidates with minimal toxicity profiles for drug delivery applications. Beyond high-throughput screening, the developed models shed light on the chemical landscape associated with high biocompatibility precursor molecules, enabling the derivation of guidelines for the rational design of biocompatible MOFs. This framework thus expedites the identification of biocompatible materials, while facilitating deeper insights into their underlying chemistry.

Examining the Determinants of Renewable Energy Consumption in the Southern African Power Pool
Authors: Aidoo Lesley
Published: June 2024

The main factors influencing the Southern African Power Pool’s (SAPP) usage of renewable energy are examined in this article. The 12 nations that constitute the SAPP are the sources of the data from 1988 to 2018. The effect of GDP, gross fixed capital formation, labour, trade, and non-renewable energy on renewable energy in SAPP is estimated using the panel ARDL method. The empirical findings suggest that, in the long run, all coefficients of explanatory variables have positive signs, except for gross fixed capital formation and non-renewable energy, which have negative signs. Furthermore, all results were statistically significant at one to five percent. This implies that the reduction in renewable energy in the SAPP is caused by non-renewable energy and gross fixed capital formation in the long run, but not by any other explanatory variable. The results also showed that each SAPP member country’s impact on renewable energy was varied. The SAPP could, therefore, encourage the adoption of renewable energy sources through the results presented in this report. Based on these findings, the study suggests that economic policies that hasten economic development and growth will increase renewable energy consumption.

Juan de Mata (c.1690 – 1747), un retablista aragonés en tierras castellano-manchegas
Authors: Sánchez García Miguel Ángel
Published: June 2024

Resumen
La presencia de escultores, doradores y pintores levantinos en tierras conquenses y albacetenses durante el siglo XVIII está bien atestiguada tanto en la documentación como en las investigaciones realizadas sobre la retablística en dichas tierras en aquella centuria. Sin embargo, la presencia de artífices llegados de otras zonas es menos conocida. Este artículo está dedicado a estudiar la figura de Juan de Mata, maestro escultor aragonés, que trabajó en la diócesis de Cuenca y en el arzobispado toledano, de cuya trayectoria vital y profesional apenas teníamos noticia.
Abstract
The presence of Levantine sculptors, gilders and painters in Cuenca and Albacete during the eighteenth century is well attested not only in the documentation, but also in the research carried out on the altarpiece in these lands in that century. However, the presence of artificers from other areas is less well known. This article is dedicated to study the figure of Juan de Mata, an Aragonese, master sculptor, who worked in the diocese of Cuenca and in the archbishopric of Toledo, and we hardly knew about his life and professional career.

Las cárceles del Steri de Palermo, investigación y musealización
Authors: Fiume Giovanna
Published: June 2024

Resumen
En 1603, el Santo Oficio inició la construcción de un nuevo edificio destinado a prisión secreta. Terminado en 1610, se añadió otro piso en 1630 con un total de catorce celdas. En sus paredes, los presos arañan, escriben, dibujan como en una página en blanco, utilizando materiales disponibles localmente. Por la coherencia y riqueza de las manifestaciones escritas, este edificio es único en comparación con otros casos de estudio y con las inscripciones y dibujos carcelarios, aunque abundantes en la época moderna.
La prisión, con sus muros historiados, representa al mismo tiempo una fuente escrita y una fuente material: autor, mensaje, soporte y contexto son inseparables y juntos constituyen un documento, la prisión es su archivo. Si tenemos en cuenta la dispersión de los documentos a lo largo de los siglos, hasta la quema tras la supresión de la corte en 1782, comprenderemos la imperiosa necesidad de salvaguardar este testimonio, inseparable del soporte y del contexto en el que se encuentra. La necesidad de preservar un artefacto delicado y perecedero debe conciliarse con su disfrute: el ensayo sugiere una posible estrategia para su conservación y uso.
Abstract
In 1603, the Holy Office initiated the construction of a new building to be used as a secret prison. Completed in 1610, another floor was added in 1630 for a total of forteen cells. On their walls the presos scratch, write, draw as if on a blank page, using locally available materials. In terms of the consistency and richness of the writing manifestations, this building is unique compared to other case studies and the abundant prison inscriptions and drawings in the modern age.
The prison, with its historicised walls, represents both a written source and a material source: author, message, medium and context are inseparable and together constitute a document; the prison is its archive. If we take into account the dispersion of the documents over the centuries, up to the burning after the suppression of the court in 1782, we can understand the imperative need to safeguard this testimony, inseparable from the medium and the context in which it is embedded. The need to preserve a delicate and perishable artefact must be reconciled with its use: the essay suggests a possible strategy.

Ammán: Leer la ciudad a través del desplazamiento
Authors: Dalal Ayham
Published: June 2024

Ammán es una ciudad moldeada por múltiples desplazamientos. En 1952 y 1955 se crearon dos campos de refugiados, llamados Al-Hussein y Al-Wihdat, respectivamente, para palestinos desplazados cerca del centro de la ciudad. Poco después la ciudad empezó a experimentar un rápido crecimiento debido a las continuas oleadas de desplazamientos. Unos años más tarde, los campos se mezclaron con el tejido urbano emergente de la ciudad. Este artículo explica esta transformación urbana y cómo provocó la polarización de la ciudad en dos partes: el empobrecido este, regido por acuerdos informales, y el rico oeste, con estructuras de apoyo formales. Después de 2011, Jordania recibió refugiados sirios, muchos de los cuales se asentaron en Ammán. Este documento aborda la siguiente cuestión: ¿cómo creció Ammán frente al desplazamiento? Y teniendo en cuenta la llegada relativamente reciente de sirios a la ciudad (en comparación con otros refugiados), ¿cómo se encontraron con la ciudad y sortearon sus disparidades socioeconómicas? Basándose en el trabajo de campo realizado en Ammán en 2022-23, el autor muestra cómo los sirios se dividieron entre las dos partes de la ciudad, y cómo los que tenían menos recursos acabaron viviendo en el este con sus campos palestinos, mientras que los que tenían más recursos luchaban por sobrevivir en el oeste de Ammán.

Atrapar lo efímero. Niebla, nubes, humo, burbujas, en la arquitectura japonesa contemporánea
Authors: López del Río Alberto
Published: June 2024

Los fenómenos atmosféricos, como las nubes o la niebla, en su manifestación más sutil, son muy apreciados por la cultura japonesa, lo que se aprecia particularmente en la literatura, la poesía o la pintura. Estos fenómenos, efímeros en su propia naturaleza, se asocian a un determinado pathos típicamente japonés, el mono no aware, que valora las cosas leves y fugaces por su propia condición cambiante y perecedera, así como por su asociación con la condición efímera de la vida humana. Estas cualidades tienen su presencia innegable en la arquitectura tradicional, muy vinculada al paisaje en el que se asienta y de naturaleza perecedera por su propia materialidad, y ya en el siglo XX y principios del XXI, la arquitectura japonesa ha buscado reestablecer una relación con la naturaleza que parecía haber desaparecido. Para ello, no sólo ha tratado de retomar la cercanía perdida, recurriendo a métodos compositivos tradicionales adaptados a los nuevos materiales, necesidades y realidades urbanas, sino que ha buscado nuevas maneras de establecer una relación poética con lo que la que rodea. Uno de los mecanismos más extendidos para conseguirlo ha sido el empleo de la metáfora, asociando el objeto arquitectónico a una imagen que le sirve de referente formal o conceptual. Es en este contexto en el que la nube, desde diversas manifestaciones, se ha revelado como una imagen fructífera a la hora de actuar como referente arquitectónico.
Bloques de hielo y piedra. Relatos sobre tiempo y materia en la obra de Miguel Ángel
Authors: Navarro de Pablos Javier , Martínez García-Posada Ángel
Published: June 2024

A través del ambiguo estado inacabado de ciertas obras de Miguel Ángel Buonarroti se recorren sus experimentaciones con el tiempo y la materia, asumidos como instrumentos de proyecto consciente. Desde una desconocida escultura efímera de hielo en el Palacio Medici hasta su última obra, la Piedad Rondanini, Miguel Ángel explora los límites de la piedra en un camino que le conduce desde la perfección del mármol pulido a la abstracción del bloque en bruto. Registrando cronológicamente sus trabajos se reconocen los achaques de la edad, como si las esculturas fuesen una extensión de sí mismo, desde el rostro adolescente de la Piedad Vaticana a la deformación física de la serie de Esclavos de la tumba de Julio II. Siglos después de su muerte, resuenan dilemas patrimoniales como el acomodo de la Rondanini en el Castello Sforzesco de Milán, que propiciaría un primer proyecto del estudio BBPR y una posterior recolocación en la que participaría infructuosamente Álvaro Siza, o la protección de las obras de la Academia de Florencia y el Museo Pushkin de Moscú durante los bombardeos aliados de la Segunda Guerra Mundial a través de sistemas efímeros que rescatan la condición liminal de las obras en construcción. A través de todas estas obras, seguimos reflexionando desde el presente sobre la idea de obra abierta, que encauza nuestras reflexiones arquitectónicas sobre arquitectura, materialidad y tiempo.
Sistemas enredados. El Método Leoz frente a la técnica constructiva
Authors: Picado Fernández Rubén , De Blas Gutiérrez de la Vega María José
Published: June 2024

Rafael Leoz fue un arquitecto enigmático entre los de su generación porque investigó en algo diferente a los demás: un método para proyectar la arquitectura del futuro; y el hecho de haber llegado a construir algunos edificios con ese ‘método’ revela la importancia de su aportación. Tras su participación en la VI Bienal de Sao Paulo de 1961, compuso una atractiva narración que, recogida en numerosas publicaciones, le ha situado al borde de la mitificación. Las investigaciones sobre su trabajo se han centrado principalmente en el ‘módulo Hele’ y en su implicación sobre la industrialización de la vivienda social y esta circunstancia es la principal razón por la que no se haya profundizado en las implicaciones de su método, recogido en el libro Redes y Ritmos Espaciales.
En sus escasos quince años de vida profesional, Leoz estableció unas relaciones muy fructíferas con artistas, pensadores y políticos, pero fue su conexión con el arte concreto y su colaboración con el CCUM (Centro de Cálculo de la Universidad de Madrid) lo que fortaleció la investigación sobre su método. Ya en los 70, la incorporación de las nuevas dimensiones geométricas de los hiper-poliedros, cuyos principios fueron esbozados en un inconcluso libro, verificó la validez del ‘Método Leoz’ con la construcción de la Embajada de España en Brasilia. El Método Leoz, aplicable tanto a la docencia como al proyecto de la arquitectura, muestra una manera de hacer que, fundamentada en su esencia modular, permite entender la creación de espacios como el resultado de una constante transformación combinatoria desplegada en el tiempo.

Yunan-Roma güləşində də idmanın digər təkmübarizlik növlərində olduğu kimi idman hazırlığının fizioloji məzmununa idman nəticələrinə nail olmaq üçün funksional ilkin şərtlərin yaradılması daxildir. İdman forması idman nəticələrinə nail olmaq üçün optimal hazırlıqdır. Bu, müəyyən bir bacarıq səviyyəsində idmançının hazırlığının ən yüksək inkişaf səviyyəsini əks etdirir. Orqanizmin optimal hazırlığı ayrı-ayrı orqan və sistemlərin yüksək funksional həddi, iş proseslərinin mükəmməl koordinasiyasını və funksiyalarını gücləndirmək qabiliyyəti, xarici və daxili mühitin mənfi amillərinin təsirinə qarşı müqavimət ilə xarakterizə olunur. İdman forması kinestetik analizatorun (məs., üzgüçülərdə “su hissi”, xizək sürənlərdə “qar hissi” və s.) funksiyalarında fizioloji dəyişikliklərlə sıx əlaqəli olan xüsusi psixoloji fon ilə xarakterizə olunur. İdman forması vəziyyətində şüurlu nəzarətin rolu və emosional vəziyyəti tənzimləmək qabiliyyəti artır. Hərəki, vegetativ və zehni fəaliyyət sahələrində belə geniş və mürəkkəb dəyişikliklər toplusu tədricən formalaşır. İdman formasını əldə etmək üçün vaxt 5-6 ay vaxt tələb olunur. Bu müddətlər həm də illik təlim dövründə hazırlıq dövrünün müddətini müəyyən edir.

Azərbaycanda dövlət müstəqilliyinin bərpasından sonra təhsil sahəsində ən əlamətdar hadisə ardıcıl və məqsədyönlü islahatların başlanması olmuşdur.
Ümummilli liderimiz Heydər Əliyev uşaq və gənclərlə bağlı çıxışlarında müstəqil Azərbaycanın gələcək inkişafında fəal iştirak etmək üçün bu günkü uşaqların hərtərəfli, harmonik inkişaf etmiş, gələcəkdə əmək fəaliyyətində yüksək nəticələr göstərə biləcək, Vətən torpağını layiqincə qoruya biləcək, sağlam və vətənpərvər vətəndaş olmaqlarını idman naliyyətlərilə respublikamızın bayrağını yüksəklərə qaldıraraq, özlərini və respublikamızı layiqli şəkildə nümayiş etdirməklərini bildirirdi.
Onun layiqli davamçısı olan Müzəffər Ali Baş Komandan, prezident İlham Əliyev qeyd etdiyi kimi Azərbaycan xalqına 44 günlük Vətən müharibəsində şəhidliyə yüksələrək, qazi olaraq, bizə qalibiyyəti bəxş edən dünənki uşaqlar, bu günkü Ana vətən torpağına bağlı olan vətənpərvər gənclərdir.
Qeyd etmək lazımdır ki, uşaqların formalaşıb inkişaf etməsində, Vətənə layiqli övlad olmasının əsas amillərindən biri də onların sağlamlığı və fiziki hazırlığıdır.
