Aguas con ojos. Pensando el agua a través de las imágenes animales de Tiwanaku
Authors: Villanueva Criales Juan
Published: March 2023

Este texto pone en tensión dos ideas sobre el agua: el modelo aristotélico del Agua como uno de los cuatro elementos primordiales de la materia, con sus cualidades inmanentes, y las ontologías andinas que propugnan múltiples instancias en que toman forma las aguas, emergiendo en sus propiedades y límites desde relaciones con espacios y personas, animales, cosas e imágenes. Las imágenes de animales acuáticos en la iconografía de Tiwanaku, percibidas con el auxilio de miradas que emanan de la etnohistoria y la etnografía andinas, permiten entender unas aguas dotadas de agencia y voluntad, que, lejos de ser asumidas como una única sustancia, deben ser criadas, aplacadas, alimentadas. La idea permite reflexionar, al final, acerca de la compleja situación en que aguas, animales, lugares y personas, como agentes en intracción constante, se encuentran en la Bolivia de hoy.
De espalda a la frontera. Equivalencia y creación/crianza de excesos
Authors: Romero Lozano Sergio Esteban
Published: March 2023

En el presente escrito pretendo poner en tensión nuestra necesidad pulsional por definir las cosas como un dispositivo de separación/exclusión que necesariamente compone toda relación de igualdad. El privilegio de la dimensión espacial necesaria para separar impide la comprensión de lo otro como un cuerpo diferente; por tanto, una noción de equivalencia que no busque la proyección formal espacial de un solo cuerpo como contenedor permitiría entender los elementos y sus relaciones dentro de la incertidumbre propia del nacimiento en un sistema de gestación vital. Parto de revisar la concepción de la noción de igualdad en la matemática para analizar cómo y qué se privilegió en la clausura del signo igual (=), para plantear cómo la idea de un «lo mismo» —que se relaciona con nuestra necesidad del definir/excluir— convivía con otros modos de la igualdad que en estos momentos resultarían más pertinentes. Finalmente, propongo la crianza como un modo de recuperar y mover el marco de la noción de igualdad hacia cosmovisiones que nos permitan otros dispositivos de creación/gestación del mundo; así también, como un concepto que puede heredar a la equivalencia una noción de vínculo con algo que, aunque en una dimensión pueda tener el mismo valor, no sólo tiene ese valor si no concibe continuamente sus propios excesos, su propio tejido de valores.

Recently, we have developed a new approach to measuring local temperatures and controlled heating using diamond particles containing luminescent “silicon-vacancy” centers (SiV). Here, in the development of this approach, the two dependencies are investigated by confocal laser spectroscopy. First, spectral characteristics of SiV-centers in diamond microparticles of various synthesis on the ambient temperature are studied. Second, the heating temperatures of diamond particles on the optical power are analyzed. The maximum temperature sensitivity of SiV-luminescence is determined for diamonds obtained at high pressures, while the maximum heating efficiency is observed for diamonds synthesized by chemical vapor deposition.

Обнаружено, что УФ-излучение с длиной волны 257 и 320 nm, не вызывает свечение А-полосы, что связано, по-видимому, с прямым межзонным фотовозбуждением алмаза.

In this paper nature crystals of the pink and brown colored diamonds with the evident plastic deformations were comprehensively studied with IR-Fourier spectroscopy and photoluminescence methods. A- and B-centers presence were revealed by IR-Fourier specters. Femtosecond (250 fs) UV-range laser pulses with wavelength of 257, 320, 352 and 365 nm inducted photoluminescence demonstrates N3 and H3 photoluminescence centers and broad structureless A-band luminescence. It was found that UV radiation with a wavelength of 257 and 320 nm does not cause A-band luminescence, which might be due to direct interband photoexcitation of diamond.

The dependence of the visible spectrum (harmonics 2 and 3/2) and the output of Cu K-alpha X-ray radiation on the energy and duration of subrelativistic intensity femtosecond laser pulse acting on a copper foil is investigated. It was found that for secondary radiation, the determining factor is the energy density, and not the intensity and duration of the pulse. The power-law dependencies of the secondary output radiation on the duration and the pulse energy have a significantly different indicator. The tendencies of changing the shape of the spectrum for regions dominated by various mechanisms of plasma heating are revealed.

The effect of focusing, taking into account self-focusing, on the interference of SRS (stimulated Raman scattering) and self-phase modulation in a 8-mm BaWO4 crystal pumped by laser pulses with a duration of 0.3 ps and a wavelength of 515 nm is experimentally studied. The maximum efficiency of SRS conversion (~23%) to the Stokes component of the ν1 = 925 cm–1 strongest mode is obtained with a lens with a focal length of 40 mm at the linear focus shift towards the rear facet of the crystal. The increase in efficiency, when the linear focus is shifted to the rear facet, is associated with an increase in the distance between the linear and nonlinear foci, which results in an increase in the effective length of the nonlinear interaction.

An analysis of ray-tracing schemes in the mid-IR range through the main model forms of rough and polished diamonds used for determining content of basic defects based on optical absorption measurements has been carried out. It is shown that in the traditional transmission measurement scheme only a small fraction of the radiation incident on the crystal is detected due to refraction and scattering in many crystals, leading to decreasing of the signal-to-noise ratio and to narrowing of the signal levels dynamic range. Practical recommendations are given and optimal variants of ray-tracing schemes through the most characteristic crystal shapes are proposed. This makes it possible to detect the maximum fraction of the radiation transmitted through the crystal, and to implement effective measurements of optical absorption in a wide dynamic range to determine the concentrations of basic defects with a high signal-to-noise ratio.

Published: March 2023

Multi-mode dynamics with Zitterbewegung of an electron in 2D Dirac crystal placed in the field of monochromatic radiation is studied. For calculations a model Hamiltonian taking into account two independent Dirac points has been used. Calculations have shown that the spectrum of electron oscillations contains a series of new (compared to the usual Zitterbewegung) frequencies. The latter, in the case of a high radiation frequency, are a combination of the Zitterbewegung frequency and frequencies that are multiples of the field frequency. In the case when the field frequency is comparable to the Zitterbewegung frequency, the spectrum of electron oscillations is determined by the field amplitude. The character of this dependence has been shown to be changed by changing of the direction of radiation polarization. The possibility of the appearance of a constant component of the electron velocity in the field of monochromatic radiation is also discussed.

Liberalization Policy and Spread of Private University in Nigeria: The North-South Dichotomy in Perspective
Authors: Ozohu-Suleiman, Ph.D. Abdulhamid , Liberty, Ph.D. Shehu Mustapha
Published: March 2023

Contemporary Nigeria provides an excellent example of a society in the labyrinth of the era of mass education. This era is particularly underscored by the quantum leap in the demand for higher education. Scholars of development studies have predicted this social change, referring to it as a significant attribute of societies in transition. Thus, in the last three decades or so, the increasing demand for higher education has been met with the liberalization of tertiary education by the federal government. Liberalization which seeks to unbundle government monopoly in the provision of tertiary education has equally been received with an impressive intervention by the private sector. Today, there are 111 private universities in Nigeria and the list is likely to grow considering the spate of applications by prospective investors. The paper seeks to examine this spectacular development in terms of the spread of investment in private university across regions. In specific terms, the paper undertakes a comparative study of southern and northern regional responses to the liberalization policy. It argues that the spread of private universities across regional divide leaves much to be desired, the implication being that a preponderance of the gains of liberalization of tertiary education is skewed against the northern region of Nigeria. This is predictably so in the light of the historical predisposing factors for western education in Southern Nigeria when compared to the north dating back to the colonial time. The paper established that apart from the historic poor reception of the north to western education, the equally poor private investment in tertiary education in the region, are some of the factors that extenuate spread. Moreover, the higher incidence of poverty in the north when compared to the south is partly responsible for the poor investment in the region, considering that the return on investment may not be attractive to sustain the enterprise. The paper concludes that though, the withdrawal of state monopoly in the provision of higher education is a welcomed development, the policy cannot be pursued at the expense of even spread that can contribute to improved access among the constituent regions. Therefore, it recommends among other that, the federal government should adopt an incremental approach towards meeting the UNESCO minimum benchmark of 26% budgetary allocation for education and that, while encouraging private participation in the provision of higher education, a deliberate policy to encourage even spread in investment in private university should be implemented.

Published: March 2023

The cultivation of pupils’ sports interests is related to the formation of pupils’ sports habits and their physical health in the future. At present, the physical condition of primary and secondary school students in China is not optimistic. Basketball, as a part of school sports, is widely carried out in schools in China. Scientific organization of basketball teaching in primary schools can better improve the physical quality of pupils and cultivate their interest in basketball. Pupils are still in the stage of physical and mental development, and their bones, muscles and nervous system are not well developed, their attention is easy to be distracted, and they can not carry out large amount of exercise, so they should focus on motivational exercise and basic teaching. As a means of teaching, games can improve pupils’ interest in the practice and stimulate their intrinsic motivation to participate in basketball, which should be appropriately increased in teaching.

Impulsos para una teología del trabajo por la paz
Authors: Siebenrock Roman A.
Published: March 2023

The biblical concept shalom is explored as a state of well-being, reconciliation, justice and love, peoples' hope, and God's gift and, then, the promise offered and realized in Jesus as the prince of peace, even in the midst of conflicts, is addressed. Next, the Church mission as a promoter of peace based on Paul VI's speech at the United Nations in 1965 is explored. Other teaching documents and prayer meetings in Assisi show that work for peace is an essential, not subordinate, part of the Church mission. Finally, work for peace is introduced as a path toward a full life in the four dimensions of human life: the smallest social unity (ubuntu), social relations, natural and cosmic integration, and the relation with the ultimate Mystery.

Evaluation of the Biomechanical Potential of Pennisetum Purpureum and Mangifera Indica Plant Roots for Sustainable Slope Stabilization
Authors: Usifo Patrick , Li-Quan Wu
Published: March 2023

Abstract: The potentials of the roots of Pennisetum purpureum and Mangifera indica for use in sustainable stabilization of slope were evaluted. The plant roots were sampled close to an erosion site in Nwonta Isuikwuato local government of Abia State Nigeria. The tensile strength of the roots segments was determined using the Universal Testing Machine (UTM) at the Michael Okpara University of Agriculture, Umudike. The effect of water content and dehydration due to adverse weather condition was studied by tensile testing the roots after different drying periods (30 minutes, 1 hour, and 24 hours). Laboratory experiments was performed to evaluate the engineering properties of the soil at the erosion site. The mean tensile strength of the Pennisetum purpureum obtained were 5.30 MPa (hydrated roots), 12.49 MPa (30 minutes dried) and 17.13 MPa (1 hour dried). After 24 hours drying the roots of Pennisetum purpureum which is a grass species was not strong enough to be tested for tensile strength. For the Mangifera indica the mean tensile strength obtained were 17.41 MPa (hydrated roots), 18.73 MPa (30 minutes dried) and 21.84 MPa (1 hour dried) and 34.10 (24 hours dried). The roots show that root tensile strength increased as the root moisture content reduces. The heightened rate of soil erosion in the study area could be due to the fact that the soils are predominantly sand with no cohesion as observed from the laboratory test. Hence, planting these vegetations can significantly lead to the improvement of the strength properties of the soil and minimise the rate of soil erosion and slope failure.

Crack Pattern an Indicator and Type of Distress in Concrete Structures: A Compilation of Causes, Measurement and Solution
Authors: Munzni B. K. , Solanki Lalit Kumar , Vidyarthi U S
Published: March 2023

Abstract: Crack occurs over time in almost all concrete which indicates distress. It varies in depth, width, direction, pattern, location, and cause. Cracks can be either active or dormant (inactive). Active cracks widen, deepen, or migrate through the concrete. Dormant cracks remain unchanged. Some dormant cracks, such as those caused by shrinkage during the curing process, pose no danger, but if left unrepaired, they can provide convenient channels for moisture penetration, which normally causes further damage. Structural cracks can result from temporary or continued overloads, uneven foundation settling, or original design inadequacies. Structural cracks are active if the overload is continued or if settlement is ongoing; they are dormant if the temporary overloads have been removed, or if differential settlement has stabilized. Thermally-induced cracks result from stresses produced by temperature changes. They frequently occur at the ends or corners of older concrete structures built without expansion joints capable of relieving such stresses. Superficial repairs do not eliminate underlying causes. To aggravate problems, professional consultation is recommended in almost every instance where noticeable crack occurs [1].
La Biopolitíca, neoliberalismo y proyecciones en la educación
Authors: Alegría Licuime Juan Esteban
Published: March 2023

El siguiente trabajo es una investigación cualitativa de carácter analítico, donde se aborda la relación entre biopolítica, neoliberalismo y educación. A partir del análisis de diversos documentos y autores, se problematizan las múltiples características que emergen de la gestión neoliberal de la escuela, donde adquieren relevancia los sistemas de control y los dispositivos disciplinarios. En nuestro país las décadas de implementación de las políticas neoliberales, cla­ramente están dando cuenta de una crisis estructural de la red pública de educación. Muestra de aquello son los reiterados conflictos y manifestaciones estudiantiles, huelgas prolongadas de docentes, precarización de los espacios laborales, etc. Lo cierto, es que la escuela como sitio del saber sistematizado parece estar en retirada, emergiendo la gestión burocrática, el disciplina­miento y la intervención psicosocial como sus aspectos más relevantes.
ON THE FEATURES OF THE FUNCTIONING OF CONSCIOUSNESS IN THE CONTEXT OF QUANTUM INFORMATION
Authors: Knyazev V. N. , Parshikova G. V.
Published: March 2023

The article deals with the relationship of ideas about the quantum-physical foundations of the functioning of consciousness with quantum computer science. The fundamental question of the nature of consciousness as a unique phenomenon characterized by self-development, adaptive functions, nonlinearity and openness remains debatable. Modern research on the so-called “quantum concept of consciousness” opens up the prospect for subsequent discoveries of new, unsolved patterns. At the junction of quantum mechanics, psychophysics and neurobiology, an interdisciplinary field of knowledge is now being formed and dynamically developing. The comprehension of the methods and formalisms developed within its framework in application to the ontological aspect of the essential nature of consciousness is chosen as the subject of research in this work. The universal laws of quantum mechanics, the concepts of quantum entanglement and the nonlocality of the wave function are important tools for understanding the role of the observer's consciousness at the quantum-molecular level (nanoscale) of consciousness functioning. The article shows that the principles of quantum data processing have a certain superiority over traditional methods of information processing and can become a significant analogue in the development of the quantum concept of consciousness. The characteristic processes of the “work” of consciousness are revealed, which cannot be comprehended without reference to entropic processes and quantum jumps at bifurcation points, entailing stochastic choice, i.e. information generation. The hypothesis of the quantum concept of consciousness is considered in relation to the macroscopic nature of consciousness, its synergetic complexity. The main conclusion is connected with the idea that the modern understanding of consciousness is undergoing many changes due to the widespread introduction of new knowledge in the field of computer science, quantum physics, and neuroscience.
FAR AND NEAR ORIGINS OF THE STANDARD MODEL IN PHYSICS OF FUNDAMENTAL INTERACTIONS (TO THE 150TH ANNIVERSARY OF F. KLEIN'S ERLANGEN PROGRAM AND TO THE 100TH ANNIVERSARY OF THE BIRTH OF C. YANG)
Authors: Vizgin V. P.
Published: March 2023

In connection with the 150th anniversary of F. Klein’s Erlangen program in geometry and the 100th anniversary of the birth of C. Yang, the main creator, non-Abelian gauge fields are discovered, the far and near sources of the standard in the physics of fundamental models of interactions are concluded. A distant source is the Erlangen program and its subsequent introduction of reaction to relative and classical physics. This material discusses the phenomenon of “inconceivable effectiveness of mathematics in special sciences” (J. Wigner), which becomes clearer on the basis of the “relay model” of the interaction between mathematics and physics proposed by D. Hilbert. The approximation of the Erlangen observation, which is applied to Noether's observations on the connection between meetings and meetings, is considered, as well as the application of the Erlangen observation to the history of physics. It is shown how the extension of this domain to local gauge domains is carried out by C. Yang and R. Millsakoch theories of non-Abelian field gauges (1954), which became a near source on the way to the standard and completed model in 1973-1974.

Vassal Mamluk rulers of Egypt and Syria in the service of the Ottomans
Authors: Ryzhenkova Tamara Alexeevna
Published: March 2023

The fall of the Mamluk Sultanate under the onslaught of the Ottoman invasion in 1516-1517 turned the entire course of events both in Egypt and throughout the Muslim world. However, the establishment of direct Turkish rule on the territory of the former Mamluk possessions was preceded by a short transitional period of vassalage. The Ottoman Sultan Selim I Yavuz (1512-1520) appointed in Egypt and Syria two devoted to him Mamluk emirs Khair-bek and Janbirdi al-Ghazali, whose actions infl the further strengthening of the power of the Turks in the Middle Eastern provinces. The main purpose of the study is to identify the reasons for such an abrupt change in the policy of the Ottomans in Egypt and Syria. The author examines in detail the period of rule of the vassal Mamluk emirs and tries to determine how their actions infl the decision of the High Porte to appoint their own governors and remove the Mamluks from power. Using the historical and genealogical method, the author begins with a description of the events of the Ottoman-Mamluk war of 1516-1517. During the confl both emirs showed far-sightedness and went over to the side of the Ottomans. Therefore, they earned the special favor of Sultan Selim. However, later, while in power, both Khair-bek and Janbirdi al-Ghazali showed a tendency to arbitrariness, which served as an alarm signal for the Ottomans. Moreover, after the death of Selim, Janbirdi openly opposed the Ottomans. The result of the reign of both commanders, therefore, was an even greater strengthening of the Turks and the further weakening of the Mamluks in the Islamic world.

Aim: To investigate the effects of farmyard manure addition, elevated CO2, soil sterilization, dry conditions, field-capacity conditions, and submerged conditions on clothianidin dissipation from the soil, as well as the effects of different pH levels, namely, pH 4.0, 7.0, and 9.2, on its dissipation from the aqueous solutions. Methodology: Samples were processed by the QuEChERS method from the soil and the dipping and shaking method from the aqueous solution, and then analyzed by Shimadzu HPLC-PDA. Results: The results revealed that clothianidin dissipation from soil and aqueous solution best fit first-order kinetics, with the coefficient of determination r2 value < 0.90. In the soil, varying clothianidin dissipation was recorded with significant impact and their decreasing dissipation rate was as follows: submerged conditions (t1/2103.7–107.5 days) > elevated CO2 (t1/2115.7–143.3 days) > farmyard manure addition (t1/2130.8–150.5 days) > field-capacity conditions (t1/2158.4–215.0 days) > dry conditions (t1/2250.8–334.4 days) > soil sterilization (t1/2342.0–376.2 days). In the aqueous solution, clothianidin dissipation was slow at pH 4.0 (t1/2430 days) but fast at pH 9.2 (t1/2273.6 d days). Interpretation: The findings suggest that clothianidin dissipation could be positively affected by FYM addition, elevated CO2, soil sterilization, dry conditions, field-capacity conditions, submerged conditions, and aqueous pH level in all the treatments. This information would help gain a better understanding of clothianidin dissipation in the environment for good agricultural practices,proper risk assessment, and monitoring guidelines.

Aim: To assess genotypes with ability to sustain yields under arid region and to understand the significance of interactive effects of genotype × environment to develop resilient cultivars for rainfed farming. Methodology: Performances of 12 pearl millet varieties and hybrids released for commercial cultivation in India, were estimated using RBD with three replications during rainy seasons of 2018, 2019 and 2020. The trials were conducted at the Agricultural Research Station, ANGRAU, Ananthapuramu, located in the Scarce Rainfall Zone of Andhra Pradesh, India, with an average annual rainfall of nearly 553 mm and 300 mm to 400 mm during rainy season. Results: The environment and genotype effects were highly significant in the Additive Main Effect and Multiplicative Interaction (AMMI) model, implying that environments are varied and genotypes performed differently in each environment offering a great scope for selecting better adaptive genotypes. Apart from moisture stress, the amount of rainfall received during both the anthesis and grain maturation stages were influenced grain yield through plant height, 1000-grain weight and dry fodder yield. Environment 3 was the best discriminating environment and the hybrids Pratap, 86M86 and NBH 5767 had outperformed the popular open pollinated varieties in ideal conditions. Interpretation: In terms of grain yield,Pusa Comp. 612 and Pratap have proved to be reliable and had a mean higher than the general mean over environments. As a result, Pusa Comp. 612 and Pratap are suggested for large-scale assessment in a wide range of locations in rainfed situations of arid regions.
