Sensitivity Analysis of Runoff and Wind with Respect to Yellow River Estuary Salinity Plume Based on FVCOM
Authors: Qin Huawei , Shi Hongyuan , Gai Yunyun , Qiao Shouwen , Li Qingjie
Published: April 2023

In 2020, Yellow River runoff was more than twice as much as past years, and the proportion of strong winds was also higher than that in past years, which will inevitably lead to a change in salinity plume distribution in the Yellow River Estuary and Laizhou Bay. Based on FVCOM numerical modelling, this paper presents the spatial salinity distribution and dispersion of the Yellow River Estuary and Laizhou Bay during the wet and dry seasons in 2020. We used data from six tidal and current stations and two salinity stations to verify the model, and the results showed that the model can simulate the local hydrodynamic and salinity distribution well. The influence of river discharge and wind speed on salinity diffusion was then investigated. The simulation results showed that under the action of residual currents, fresh water from the Yellow River spread to Laizhou Bay, and the low salinity area of Laizhou Bay was mainly distributed in the northwest. The envelope area of 27 psu isohaline can account for about one-quarter of Laizhou Bay in the wet season, while the low-salinity area was only concentrated near the estuary of Yellow River in the dry season. River discharge mainly affects the diffusion area and depth of fresh water, and wind can change the diffusion structure and direction. In the wet season, with the increase in wind speed, the surface area of the plume decreased gradually, and the direction of the fresh water plume changed counterclockwise from south to north. During the dry season, the plume spread to the northwest along the nearshore. The increase in wind speed in the early stage increased the surface plume area, and the plume area decreased above a wind speed of 10 m/s due to the change in the turbulence structure. The model developed and the results from this study provide valuable information for establishing robust water resource regulations for the Yellow River. This is particularly important to ensure that the areas with low salinity in the Yellow River Estuary will not decrease and affect the reproduction of fish species.

Published: April 2023

Concerns regarding plastic pollution, especially microplastics, have increased, as they can be present in different environmental compartments, including estuarine areas and saltmarshes. Although saltmarshes are highly vulnerable to different human activities and pressures, they have the ability to trap/retain contaminants in their vegetated sediments. However, there is still little information regarding the role of saltmarshes in microplastic retention. Thus, the present study aims to investigate the capability of an estuarine saltmarsh to trap microplastics by comparing microplastic concentrations in vegetated (saltmarsh) and non-vegetated sediments. Microplastic content from sediment (vegetated and non-vegetated) samples collected at different sampling sites in Lima River estuary was estimated using previously optimised extraction protocols, and the observed particles were then characterised accordingly to their size, colour, shape, and polymer (by FTIR). Water samples were also collected and analysed for their microplastics content to complement MPs characterisation within the estuarine area. Microplastics were detected in all sediment samples, with fibres being the most common type of microplastic found, followed by fragments/particles. Overall, vegetated sediments, especially those of saltmarsh species Juncus maritimus, presented a higher number of plastic items. These results indicated that microplastics tend to be trapped in vegetated sediments, supporting the fact that saltmarshes have a significant influence on the transport, distribution, and accumulation of MPs in estuarine areas.

Published: April 2023

This paper represents the results of a study of the chemical composition of salt lakes within the Burabay rock mass in eastern Kazakhstan. We sampled water and bottom deposits, geochemically analyzed the composition of the salt lakes, and performed aerial photography of the lakes to geometrize them. We studied the linkage between the rare-metal mineralization of granites of the Burabay rock mass and the salt lakes within the territory. Based on the obtained data, we identified the prospects of the survey area for rare metals. The surveys included 15 water samples and 15 bottom-deposit samples. To identify the source of salt in the lake water and deposits, the chemical composition of Burabay rocks was analyzed and seven samples of coarse-grained and porphyritic granites were selected. It was established that the water and bottom deposits accumulated elevated concentrations of valuable components (i.e., Sr, Rb, and U); this fact may be considered as an argument for conducting special surveys of small lakes in the region. The results obtained can be used for conducting further explorations and mining operations in the survey area in order to revive the rare-metal industry in the region, which will allow the development of new high-tech production and the creation of new jobs in this sphere.
Flood Frequency Analysis Using the Gamma Family Probability Distributions
Authors: Ilinca Cornel , Anghel Cristian Gabriel
Published: April 2023

This article presents six probability distributions from the gamma family with three parameters for the flood frequency analysis in hydrology. The choice of the gamma family of statistical distributions was driven by its frequent use in hydrology. In the Faculty of Hydrotechnics, the improvement of the estimation of maximum flows, including the methodological bases for the realization of a regionalization study with the linear moments method with the corrected parameters, was researched and is an element of novelty. The linear moments method performs better than the method of ordinary moments because it avoids the choice of skewness depending on the origin of the flows, and is the method practiced in Romania. The L-moments method conforms to the current trend for estimating the parameters of statistical distributions. Observed data from hydrometric stations are of relatively short length, so the statistical parameters that characterize them are of a sample that requires correction. The correction of the statistical parameters is proposed using the method of least squares based on the inverse functions of the statistical distributions expressed with the frequency factor for L-moments. All the necessary elements for their use are presented, such as quantile functions, the exact and approximate relations for estimating parameters, and frequency factors. A flood frequency analysis case study was carried out for the Ialomita river to verify the proposed methodology. The performance of this distributions is evaluated using Kling–Gupta and Nash–Sutcliff coefficients.
Evaluating the Effect of Deforestation on Decadal Runoffs in Malaysia Using the Revised Curve Number Rainfall Runoff Approach
Authors: Khor Jen Feng , Lim Steven , Ling Lloyd
Published: April 2023

This study presents a revised and calibrated Soil Conservation Service (SCS) curve number (CN) rainfall runoff model for predicting runoff in Malaysia using a new power correlation Ia = SL, where L represents the initial abstraction coefficient ratio. The traditional SCS-CN model with the proposed relation Ia = 0.2S is found to be unreliable, and the revised model exhibits improved accuracy. The study emphasizes the need to design flood control infrastructure based on the maximum estimated runoff amount to avoid underestimation of the runoff volume. If the flood control infrastructure is designed based on the optimum CN0.2 values, it could lead to an underestimation of the runoff volume of 50,100 m3 per 1 km2 catchment area in Malaysia. The forest areas reduced by 25% in Peninsular Malaysia from the 1970s to the 1990s and 9% in East Malaysia from the 1980s to the 2010s, which was accompanied by an increase in decadal runoff difference, with the most significant rises of 108% in Peninsular Malaysia from the 1970s to the 1990s and 32% in East Malaysia from the 1980s to the 2010s. This study recommends taking land use changes into account during flood prevention planning to effectively address flood issues. Overall, the findings of this study have significant implications for flood prevention and land use management in Malaysia. The revised model presents a viable alternative to the conventional SCS-CN model, with a focus on estimating the maximum runoff amount and accounting for land use alterations in flood prevention planning. This approach has the potential to enhance flood management in the region.
Una radiografía de las tasas de interés bancarias para las pymes en México
Authors: Chavarín Rodríguez Rubén
Published: April 2023

El objetivo general del presente trabajo es estudiar la evolución de las tasas de interés bancarias cobradas a las pymes en México, por medio de la revisión de las trayectorias individuales de 14 bancos representativos del sistema bancario mexicano. En particular, se analiza si existe una relación de largo plazo (mediante las pruebas de cointegración de Johansen y de Gregory-Hansen) entre la serie de la tasa de referencia TIIE 28 días y la serie de tasa de interés para Pymes de cada banco. Los resultados muestran que el seguir la misma trayectoria de largo plazo que la tasa de referencia no asegura una conducta competitiva (en precios) por parte de los bancos. Los bancos de escala grande son los únicos capaces de cobrar tasas por encima de la tasa promedio del mercado. Además, no existe una relación entre el nivel de las tasas fijadas por los bancos y su participación de mercado en el crédito a las pymes, lo cual significa que las tasas de interés no representan una variable fundamental de competencia en dicho mercado.
Représentations féminines et masculines chez des patientes présentant un syndrome sec
Authors: Baudin Marianne
Published: April 2023

Marianne Baudin, Representaciones femeninas y masculinas en las pacientes que presentan

un síndrome seco.

El síndrome seco es una patología autoinmune esencialmente femenina que interroga de manera directa la expresión de los deseos y los afectos (sequedad de lágrimas, secreciones salivales y vaginales).

El análisis de las representaciones femeninas y masculinas en el Rorschach y en el TAT de 36 pacientes muestra que todas estas mujeres se ven confrontadas a una herida, tanto del cuerpo real como del cuerpo fantasmático.

Ello, sea cual fuere la gravedad de la enfermedad, va a interrogar nuevamente el trabajo psíquico del complejo de castración, y las orientaciones libidinales, narcisísticas y objetales.

Las diferencias aparecen entre las pacientes de acuerdo a su edad : las de edad mas avanzada se tornan de manera privilegiada hacia el polo masculino, sobre el que se desplazan las descalificaciones castradoras ; las pacientes mâs jóvenes se mantienen en una búsqueda del doble narcisistico con el fin de atenuar el sufrimiento de su feminidad.

Évelyne Séchaud, Del vínculo a la mancha. Abuela y nieta : un lazo singular.

A partir de una escena observada entre una abuela patenta y su nieta, se exponen algunos aspectos de la problemática femenina en su desarrollo pulsional y objetal. Por un lado, la representation de una mancha, viene a réunir en lo visual, lo anal y lo sexual de la sangre menstrual. Entre abuela y nieta circulan las representaciones enigmticas de la sexualidad femenina. Por otro lado, la lectura analitica del cuento de Charles Perrault, Caperucita roja, viene a apoyar la idea que, abuela y nieta, están unidas por el secreto de su amor hacia el mismo hombre, hijo de una y padre de la otra. Este lazo que las une, provee a la nieta un sostén dentro de su cambio de objeto inicial y un modelo identificatorio.

La temporalité au féminin : une représentation paradoxale
Authors: Breucker Marie-Noëlle
Published: April 2023

Marie-Nöelle Breucker, The temporality of femininity : a paradoxical representation.

When dealing with the articulation between temporality and femininity, the question of the origin of temporality arises, which contains a part of inescapable violence in the process of integrating the "infans". The conflictual nature of conscious, preconscious and unconscious representations of time attest to the paradoxical nature of its experience. But is there a temporal paradox of femininity ? This could be considered from two perspectives: the femininity of bisexuality and psychofemininity. Puberty gives us an example of the confrontation of cyclical time and the necessary inscription within the arrow of time. This specificity of femininity can be found as an evocation in fairytales and as a repetition in the transference that occurs during psychoanalytic treatment. This is how the inescapableness of the féminin superego and masochism, the immoderateness of narcisism and the unbearableness of anxiety and castration can be seen.

Key-words : Temporality, Femininity, Representation, Psychoanalytic treatment, Fairy tale.

El libro de Roy Schafer : L' interpretación psicoanalítica del Rorschach representa desde hace ya cuarenta años, une referencia de la evaluación psicológica de orientación psicodinámica. En este artículo la contribución de Schafer es reexaminada a la luz de recientes investigaciones sobre el Rorschach. Luego de un resumen de los capítulos principales de Schafer, nosotros hacemos una relectura crítica de su abordaje del Rorchach a partir de la práctica moderna de la evaluación. Las diferencias entre las bases epistemológicas de los métodos psicoanalítico y empirico de interpretación del Rorschach son puestos en evidencia y las perspectivas de una integración de estos dos puntos de vistas son analizados. Como conclusión : la contribución de Schafer se descubre tari innovadora hoy como hace cuarenta años.
La compulsion à penser. De l'Homme aux Rats à Schreber
Authors: Perron Roger
Published: April 2023

Chez ces deux patients célèbres de Freud, le fonctionnement de la pensée est marqué par l'angoisse du vide, un vide propice au surgissement d'images et de représentations torturantes ; un incessant travail de pensée tente alors de prêter sens au non-sens et de coordonner ces représentations chargées d'angoisse ; dans l'un et l'autre cas ceci débouche sur une compulsion à penser qui ne laisse au malade aucun répit.

Cependant les différences sont évidentes : dans le cas de névrose obsessionnelle (l'Homme aux Rats), le malade sait qu'il s'agit de ses propres processus psychiques ; dans le cas de la paranoïa (Schreber) la projection fonctionne massivement pour imputer à une origine extérieure les causes des phénomènes constatés ; et Schreber va beaucoup plus loin que l'Homme aux Rats dans la recherche de cohérence, jusqu'à élaborer un nouveau monde.

Sur la base de cette étude sont suggérées quelques réflexions en prise sur la « clinique quotidienne ».

Un cas de dépression limite éclairé par le Rorschach associatif : Catherine
Authors: Bloch-Jacquot Florence
Published: April 2023

À partir des propositions théoriques de J. Bergeret situant les problématiques dépressives, l'étude de cas proposée présente l'intérêt de la méthode associative d'inspiration psychanalytique du Rorschach ou « Rorschach associatif » (de Tychey) dans des perspectives diagnostiques et thérapeutiques des dépressions. Le Rorschach associatif permet de mettre à jour la nature de l'angoisse dominante, le type de relation d'objet, les lieux de conflictualité et les ratés de la symbolisation. La psychogenèse de l'organisation psychique peut être abordée puisque la consigne invite le sujet à s'interroger sur le lien entre sa réalité interne et la réalité externe de ses expériences passées.

Caroline Chomé, Stéphanie Devisscher y Luc Mubikangiey, La creación del cuento maravilloso en el niño : actividad de mediación y de simbolización.

Los autores presentan la primera hoja de una investigación consagrada a la concepción de un instrumento proyectivo cuyos fundamentos y principios se inspiran directamente del cuento maravilloso. Partiendo de ciertas características del cuento tradicional, los autores han invitado a niños de 8 años a crear sus propios relatos de cuento. Las proposiciones que sostienen la gestión de los autores pueden resumirse de la siguiente manera : a) la creación de un relato maravilloso compromete la proyección de la realidad interna del sujeto ; b) por su estructura interna, el cuento opera como un contenido de dife- rentes expresiones y figuraciones de los fantasmas inconscientes. Los resultados son analizados y discutidos dentro de una doble perspectiva : una, centrada sobre el instrumento, considéra la función mediadora del cuento maravilloso, el otro, basado en la comparación de los relatos, se interesa al estatuto del objeto en la realidad psíquica así como a los procesos de simbolización que permiten la elaboración.

Monika Boekholt and Simone Cottin, Infantile psychopathology and the elaboration of the depressive position : a projective clinical perspective.

Starting from the field of infantile psychopathology and the projective approach, the authors propose to center their reflection on the organizational axes of psychic life before the appearance of oedipal constructions. In so doing, they evoke three very different clinical examples : hysteria, psychosis and the consequences of a severe somatic disturbance to underline the key position of the elaboration of the depressive position in the appearance or the extinction of pathological processes.

La bidimensionnalité de l'espace psychique chez l'enfant asthmatique. Étude clinique à partir du « dessin d'une maison avec quelqu'un à l'intérieur »
Authors: Moyano Olivier
Published: April 2023

Olivier Moyano, The bidimensionality of psychic space in the asthmatic child. A clinical study from the « drawing of a house with someone inside ».

The asthmatic child suffers from a pathology of psychic space as a consequence of the specific organizational mode of his object relations. The allergy spatializes intersubjective relations in a mode of bidimensionality and reciprocal inclusion, both at the level of psychic and real space. The present study shows that although this aspect of psychic dimensionality can remain discreet or ever hidden ordinarily, whenever the asthmatic child suffers from an affective upset, it becomes very visible again, demonstrating the possibilities of regression of the allergic subject depending on the variations in his relations to the other person. This bidimensionality can be seen in the child's drawing (following instructions : « Draw a house with someone inside »).

Seeking new strategies to tune the intrinsic defect and optimize the thermoelectric performance via no or less use of external doped elements (i.e., plain optimization) is an important method to realize the sustainable development of thermoelectric materials. Meanwhile, creating dislocation defects in oxide systems is quite challenging because the rigid and stiff ionic/covalent bonds can hardly tolerate the large strain energy associated with dislocations. Herein, taking BiCuSeO oxide as an example, the present work reports a successful construction of dense lattice dislocations in BiCuSeO by self-doping of Se at the O site (i.e., Se
O
self-substitution), and achieves plain optimization of the thermoelectric properties with only external Pb doping. Owing to the self-substitution-induced large lattice distortion and the potential reinforcement effect by Pb doping, high-density (about 3.0 × 10

Serving as targeting ligands, aptamers have shown promise in precision medicine. However, the lack of knowledge of the biosafety and metabolism patterns in the human body largely impeded aptamers’ clinical translation. To bridge this gap, here we report the first-in-human pharmacokinetics study of protein tyrosine kinase 7 targeted SGC8 aptamer via in vivo PET tracking of gallium-68 (
68
Ga) radiolabeled aptamers. The specificity and binding affinity of a radiolabeled aptamer, named
68
Ga[Ga]-NOTA-SGC8, were maintained as proven in vitro. Further preclinical biosafety and biodistribution evaluation confirmed that aptamers have no biotoxicity, potential mutation risks, or genotoxicity at high dosage (40 mg/kg). Based on this result, a first-in-human clinical trial was approved and carried out to evaluate the circulation and metabolism profiles, as well as biosafety, of the radiolabeled SGC8 aptamer in the human body. Taking advantage of the cutting-edge total-body PET, the aptamers’ distribution pattern in the human body was acquired in a dynamic fashion. This study revealed that radiolabeled aptamers are harmless to normal organs and most of them are accumulated in the kidney and cleared from the bladder via urine, which agrees with preclinical studies. Meanwhile, a physiologically based pharmacokinetic model of aptamer was developed, which could potentially predict therapeutic responses and plan personalized treatment strategies. This research studied the biosafety and dynamic pharmacokinetics of aptamers in the human body for the first time, as well as demonstrated the capability of novel molecular imaging fashion in drug development.

¿Cumple la formación docente con las condiciones de importancia, oportunidad, innovación y actualidad suficientes como para justificar que la Revista Iberoamericana de Educación dedique un número monográfico al tema?

Este número 33 de la Revista –y quizás otros en el futuro– intenta ser una respuesta a ese interrogante. En todo caso, el constante resurgir del tema en publicaciones, conferencias, reuniones y declaraciones parece indicar que existe un problema, o aspectos del mismo, que no están adecuadamente resueltos.

Este pudo haber sido el sentido que los ministros de Educación de Iberoamérica dieron al Plan de Cooperación para la Formación Docente que aprobaron en la XIII Conferencia Iberoamericana de Educación (Tarija, Bolivia, 2003).

Resulta evidente y necesario que la recuperación de un tema clásico en la literatura educativa se hiciese desde un marco interpretativo de la realidad en la que se produce hoy tanto la formación como el desempeño docente.

THE INFLUENCE OF MATHEMATICS TEACHERS' JOB SATISFACTION AND MOTIVATION ON THE USE OF DIGITAL MATHEMATICS TEACHING MATERIALS IN ELEMENTARY SCHOOLS
Authors: Kolin Ellysuzyla Jerry , Siew Nyet Moi
Published: April 2023

The use of digital teaching aids in the online teaching and learning (TL) process of Mathematics is synonymous during the era of the Covid-19 pandemic. However, online TL is not easy for Mathematics teachers. Teacher job satisfaction and motivation should be taken into account as a result of this pandemic era. Therefore, a survey study was conducted to examine the influence of job satisfaction and motivation of Mathematics teachers on the use of digital teaching aids in primary schools in North West Coast, Sabah. A total of 242 primary school Mathematics teachers were selected using simple random sampling. This study was a quantitative study using a survey research design. Data was collected using three questionnaires that each measured the level of job satisfaction, motivation and the use of mathematics digital teaching aids among teachers. The findings of the study found that the level of job satisfaction, motivation and the use of mathematics digital teaching aids were at a high level (Mean > 3.90). Meanwhile, job satisfaction and motivation were found to have a positive and significant relationship (rJS = .638, p < .05; rm = .541, p < .05) and influence (BetaJS = .492, tJS = 9.304, p < .05; Betam = .309, t m= 5.838, p < .05) on the use of mathematics digital teaching aids. This study can be used as a guide and measure for those responsible for planning and implementing efforts to improve the level of mathematics achievement of students in primary schools.
Higher-order topological sound transport in synthetic spaces
Authors: Zheng Taotao , Zhou Yuxiang , Ge Hao , Xu Chudong , Lu Ming-Hui
Published: April 2023

We design a four-dimensional system with straight waveguides composed of coordinate-dependent coupled waveguides. By controlling the phase in synthetic space and the excitation of the corresponding sound source mode, we show that the pumping incorporating adiabatic modulation of discretely varied coupling waveguides along a given orbit in the phason space occurs only in specific space directions. In addition, robust corner-to-corner topological pumping is achieved in finite-sized two-dimensional modulated acoustic structures. Our results provide a general strategy to achieve topological pumping through discrete property modulations and pave new paths for studying higher-dimensional topological phases in discrete systems.

The roasting stage is one of the most important steps in the manufacture of cocoa powder. In the roasting process, a distinctive flavor and color are formed, besides that it will reduce the acid content in cacao, cell wall swelling is caused by protein hydrolysis and water absorption. However, the color and flavor formed still vary greatly depending on the length of the roasting process, temperature, and the tools used. The Field Work Practice (PKL) activities carried out aim to find out the cocoa processing process to become the final product. There are two types of cocoa produced at the Pagergunung factory, namely edel, and bulk types. The stages of cocoa processing carried out at the Pagergunung Factory include the stages of receiving, fermenting, drying, tempering, sorting, mixing, and packaging. One of the processes that determine the distinctive flavor and color of chocolate products is the roasting process. The roasting process carried out at the Pagergunung Glenmore Factory is carried out as much as 10 kg per roast at a temperature of 100°-120°C to make the texture of the cocoa beans more crunchy even though there is a weight loss of 1.5 kg. With this roasting method, the signature chocolate of the Glenmore Pager Mountain Factory is produced.

The restriction on an individual’s physical functioning, mobility and other functions of daily living pertains to impact one’s life in many aspects. But psychological buildups are of more important in order to adjust with physical disability in routine life. The current study stressed on to explore the relationship between self-efficacy and internalized psychological problems (depression, anxiety and stress) in physically disabled adolescents and find the gender differences in self-efficacy and internalized psychological problems. The sample was consisted of 100 adolescents (50 males and 50 females-age ranging from 13 to 17 years) were selected from the special educational institutes of physically disabled adolescents, Lahore. The Generalized Self-Efficacy Scale (Schwarzer & Jerusalem, 1993), DASS-21 (Lovibond & Lovibond, 1995) and Demographic Form was used in this research to measure the variables. The data was analyzed through SPSS and Pearson Product Coefficient Correlation and independent sample t-test were used. Results showed the significant negative correlation between self-efficacy and internalized psychological problems. Gender differences were significant on self-efficacy and internalized psychological problems.

O artigo apresenta reflexões sobre dificuldades de aprendizagem em Matemática de três turmas de 1º ano do Ensino Médio de uma escola estadual do Rio Grande do Sul. Trata-se de uma pesquisa quanti-qualitativa, com aproximações de um estudo de caso. A partir de um estudo bibliográfico sobre o ensino da Matemática e as dificuldades de aprendizagem, e de uma pesquisa de campo com 87 estudantes do 1º ano do Ensino Médio, procuram-se identificar causas das dificuldades de aprendizagem em Matemática. Verificou-se que as dificuldades estão relacionadas com o grau de dificuldade dos conteúdos trabalhados em sala de aula, a falta de interesse dos estudantes para aprender e a falta de conhecimentos básicos de conteúdos desenvolvidos no Ensino Fundamental. Diante do exposto, sugere-se reorganização curricular, valorizando a postura ativa do estudante e o desenvolvimento de habilidades e competências; dinamização de estratégias de ensino; inovação de materiais didáticos; e ressignificação do processo avaliativo.
Designing ultra-fast all-optical full-subtractor using the photonic crystal structure
Authors: Pakrai Forogh , Soroosh Mohammad , Ganji Jabbar
Published: April 2023

In this paper, a photonic crystal-based structure for an all-optical full-subtractor has been proposed. The structure includes six nonlinear resonant rings to transmit the incoming optical waves toward the output ports. Using the different radii for nonlinear rods made the possibility of the dropping operation for different amounts of optical intensities. The nonlinear rods are made of a doped-glass with an optical Kerr coefficient of 10–15 m2/W. To calculate the components of the optical waves throughout the structure, the finite-difference time-domain method has been used. The simulation results prove the correct functionality of the proposed structure. Besides, the maximum rise time of the device is equal to 2 ps. The contrast ratio and the area of the structure are around 8.08 dB and 2790 µm2, respectively.

Published: April 2023

In this paper, performance analysis of free space optical (FSO) system operating in conditions of strong atmospheric turbulence over Gamma–Chi-square turbulence model, has been carried out. We have observed reception over multi-pulse pulse-position (MPPM) modulation format for the case of strong atmospheric turbulence conditions modeled with Gamma–Chi-square turbulence model and have compared it with turbulence modeling distributions such are: Gamma–Gamma distribution, K-distribution, negative exponential distribution, log–normal distribution. First, we have provided closed-form analytical expressions for average bit error rate (ABER) at the reception for each observed case and then based on them, we have obtained numerical and Monte Carlo simulation results in order to observe turbulence level impact on system performance.

Experimental studies of concrete relaxation in various modes

Published: April 2023

Introduction.At present, creep is the main parameter determined in the long-term loading tests of concrete samples. However, creep appears to be only one of the deformation properties of a concrete sample during operation under the action of long-term loading. Another important property involves stress relaxation. Moreover, in individual problems (temperature problems, force redistribution problems, etc.), stress relaxation plays a more important role than creep. The introduction of a new test procedure can improve the accuracy of the obtained results (in standard creep tests, concrete relaxation is determined only mathematically), which in turn will increase the accuracy of calculations.

Aim.To develop a procedure for testing concrete samples with the determination of their stress relaxation.

Materials and methods.The article describes a methodology for conducting an experiment to study the relaxation of concrete samples in compression and bending modes, as well as the parameters of test benches, samples and the principles of load transfer.

Results.The main results of experimental studies are presented graphically. An analysis of the results obtained was carried out; the convenience of conducting tests was evaluated.

Conclusion.The prospects of the proposed approach for testing concrete samples are demonstrated, and recommendations for amending GOST 24544 are prepared.

Se presenta el análisis de tres sitios arqueológicos con representaciones rupestres ubicados en la Estancia la Criolla, localizada al sur del lago Cardiel (Santa Cruz, Argentina). En ellos se identificó una baja frecuencia de motivos, con una alta diversidad morfológica, realizados mediante técnicas de grabado y pintura. Así, se aporta información sobre el espacio intermedio que vincula dos grandes áreas con una extensa trayectoria de investigación científica como son el lago Cardiel y la meseta del Cardiel Chico. Los resultados alcanzados sobre el análisis de pátinas, desvaídos y superposiciones de los grabados y pinturas permiten sugerir la existencia de al menos tres momentos de ejecución de este registro rupestre, los cuales contextualizan las ocupaciones humanas del área desde el Holoceno medio hasta el siglo XX.
