“El pasado que debemos llevarnos al porvenir”: Compensación, modernidad y recuerdo en la filosofía de Odo Marquard
Authors: Pérez Baquero Rafael
Published: January 2024

This paper aims at offering an interpretation and critique of Odo Marquard’s philosophy regarding his analysis on the complex relationship between past and present within our regimen of historicity. By resorting to the conceptual tools of philosophy of history and by delving further into Marquard’s notion of “compensation” and his interpretation of modernity, this paper explores the different layers sourrounding his approach to the philosophical problem of historical time. Such interpretation will bring new light into the potentialities and weaknesses of Marquard’s philosophy.

El objetivo fundamental de este artículo es el de ofrecer una interpretación y crítica del pensamiento filosófico de Odo Marquard, con especial atención a la potencialidad heurística de su análisis para interpretar las complejas relaciones entre pasado y presente que se proyectan desde nuestro régimen de historicidad. Desde el ámbito de la filosofía de la historia contemporánea, profundizaremos en su noción de “compensación” y en su interpretación de la modernidad para explorar los diferentes estratos que subyacen a la aproximación de Marquard al problema del tiempo histórico. Ello nos permitirá sacar a la luz tanto las fortalezas de su análisis como sus debilidades.

Introduction: In clinical practice, the functional tests used to assess the risk of falls require precision techniques and elements that avoid subjectivity. The use of the Wii Balance Board (WBB) is an alternative to the above, since it is an inexpensive, portable tool that allows extracting variables that are related to the phenomenon under study.Objective: To classify the variables derived from the center of pressure (CoP) during the evaluation of postural control through the WBB, in older adults with and without risk of falls.Methods: A descriptive research design was used. A total of 40 older adults were studied, 20 with and 20 without risk of falls. Postural control was evaluated using the WBB, extracting kinetic and kinematic variables, which allowed the implementation of an attribute selector and the SVM algorithm (SVMs, Support Vector Machines), identifying older adults at risk of falls.Results: The variables that best allow us to classify older adults with and without risk of falling were speed, displacement and mean force. A two-class classifier was built, whose best performance was the Kappa index 0.95 (almost perfect agreement strength), 98% sensitivity, and 100% specificity.Conclusions: The use of WBB can be considered a low-cost alternative for the evaluation of the risk of falls in older adults.

Introducción: En la práctica clínica las pruebas funcionales utilizadas para evaluar el riesgo de caídas requieren de técnicas y elementos de precisión que eviten la subjetividad. El uso de la Wii Balance Board (WBB) es una alternativa ante lo expuesto, ya que es una herramienta económica, portátil y que permite extraer variables que se relacionan con el fenómeno en estudio.

Objetivo: Clasificar las variables derivadas del centro de presión (CoP) durante la evaluación del control postural por medio de la WBB, en adultos mayores con y sin riesgo de caídas.

Métodos: Se utilizó un diseño de investigación descriptivo. Se estudió a 40 adultos mayores, 20 con y 20 sin riesgo de caídas. El control postural fue evaluado mediante la WBB, extrayendo variables cinéticas y cinemáticas, que permitieron implementar un selector de atributos y el algoritmo SVM (SVMs, del inglés Support Vector Machines), identificando a los adultos mayores con riesgo de caídas.

Resultados: Las variables que mejor permiten clasificar a los adultos mayores con y sin riesgo de caída fueron la velocidad, desplazamiento y fuerza media. Se construyó un clasificador de dos clases, cuyo mejor desempeño fue el índice Kappa 0,95 (fuerza de concordancia casi perfecta), sensibilidad 98%, y especificidad 100%.

Conclusiones: El uso de WBB puede ser considerada una alternativa de bajo costo para la evaluación del riesgo de caídas en adultos mayores.
From Description to Transformation
Authors: Gleissner Leyla Sophie
Published: January 2024

In this paper, I investigate whether phenomenological description can help in transforming an unjust or violent situation. If one can agree that describing the situation of a group of marginalised subjects is necessary in order to define what is going wrong, then the question of whether the method can help change these states, remains unanswered. With this in mind, I then suggest that phenomenological description can only serve critical causes, under the condition that it takes the transformative power of language into account: by describing our experiences we already transform them. To this end, I draw on deconstructivist approaches, which focus on language as a social act of addressing oneself to others. I conclude by arguing that description can itself be a transformative tool – if we stress how it takes place under conditions of address that necessarily shape the experience to be described.

Published: January 2024

The purpose of this study is to study the direction of the development of daycare centers as a way to expand and revitalize the 0 to 1-year-old childcare center project, which is a specialized childcare project in Gyeonggi-do. The 0-year-old childcare center in Gyeonggi-do is the first childcare facility for 0 to 1-year-olds in the country in 2008 so that dual-income families can trust and entrust their children. In-depth interviews were conducted to study ways to expand and revitalize the specialized childcare projects in Gyeonggi-do, and the study participants consisted of four directors and three teachers working at a daycare center for 0 to 1-year-olds in Gyeonggi-do. In the process of searching for data, the ratio of teachers to children, the demand for specialized infant curriculum, the concerns over the integration of kindergartens and daycare centers, the director's concurrent position as teachers, and the demand for improvement of the childcare environment were found. Based on the demand for improvement, the policy proposals for the future development direction of daycare centers are as follows. First, support for the mandatory infant professional curriculum and in-depth curriculum for the professional reinforcement education of 0 to 1-year-old teachers was derived as an alternative. Second, the need for a review since 2015 was mentioned as a discussion on the director's concurrent position as a teacher, and the need to seriously consider whether the clarification of guidelines and supervision are well followed and effective was proposed. Third, we proposed to improve the environment for professional infant care by improving the childcare environment, secure the expertise of cooks, and devise measures to resolve the difficulty of preparing infant textbooks and parish play. Fourth, we proposed to provide services for customized care at the birth registration stage through active promotion of daycare centers for children aged 0 years. Based on this, we hope that the daycare center for children aged 0 to 1in Gyeonggi-do will be expanded and revitalized to start discussions to develop.

Authors:   The Korea Parents Education Association, Kim Sang Ok , Kim Eung Ja
Published: January 2024

The aim of this study is to investigate parents' perceptions of their children's game use and game literacy. For this study, 523 parents of children aged 3 to 6 were surveyed. The survey consisted of parents' perception of game use, children's game use status, and perception of game literacy, and the collected data was used to measure the level of parents' awareness through descriptive statistical analysis.
The research results are as follows. First, parents perceived their children's game use as having a negative impact on their children's development and emotions and appeared to control and guide their children's game use. Second, regarding the child's game use pattern, the child was using games in a healthy way and the level of game over-immersion was low by appropriately controlling game use. Third, regarding game literacy, game education for children and parent education to guide children were necessary, and education on healthy game use, positive and negative effects of games, and discernment about games was needed. Game education was also necessary to provide information. Regarding game literacy, there was recognition that information about useful games and education for children and parents about games at the daycare/kindergarten level were necessary.
The results of this study suggest that it is necessary to strengthen support for game literacy education for parents, to supply game content suitable for children, and to resolve negative perceptions of early childhood game use in the educational field. This study is meaningful in that it provides basic data for applying children's correct game use and game literacy to education by grasping the status of children's game use and game literacy recognized by parents in the reality that children's game use is increasing.

UMA PROPOSTA PARA AVALIAÇÃO DO RISCO DE CRÉDITO EM FINANCIAMENTOS DE LONGO PRAZO
Authors: Moura Heber José de
Published: January 2024

Propõe um processo para quantificação do risco de crédito associado a financiamentos de longo prazo. A proposta baseia-se na obtenção dos fluxos de caixa representativos da capacidade de pagamento das empresas, realizando o desconto financeiro a partir de uma taxa que engloba os principais fatores de risco associados à operação. Mostra que a avaliação do risco em projetos de longo prazo tem como peculiaridade o elevado grau de dificuldade para realizar projeções a respeito dos fluxos de caixa futuros das empresas. Isto porque, entre o instante da análise e o efetivo reembolso das obrigações assumidas pelo tomador do crédito, podem ocorrer variações significativas nas condições ambientais sobre as quais a empresa se situa, de tal forma que venham a alterar radicalmente as previsões feitas a partir do comportamento anterior das mesmas. O trabalho mostra a necessidade da adição de variáveis ambientais no processo de previsão de fluxo de caixa, para maior consistência na avaliação do risco de crédito.

WIFI-Based Human Identification of gait recognition in muti-scenario
Authors: Bai Ziyu
Published: January 2024

With the development of 5G and the maturity of embedded technology, the Internet of Things has become the most promising technology at present, and human motion recognition and fingerprint feature recognition are hot research topics in the Internet of Things. At the same time, the way of human-computer interaction no longer satisfies the interaction only through screens and our computing devices. We hope to achieve human-computer interaction through simpler and more direct operations. For example, gestures, speech, etc., while the current methods of human recognition are mostly achieved through video or wearable devices, both of which have certain limitations. For example, when using video devices to recognize human bodies, it is necessary to ensure that there are no obstacles on the line of sight (LOS) in the video and sufficient ambient light is available. The Wi-Fi recognition method proposed in this article has the advantages of non-wearable, no light source restriction, and the ability to achieve human recognition using non-line-of-sight paths. Wi-Fi is ubiquitous in modern society, so using Wi-Fi signals for indoor human sensing has important research value. Based on existing Wi-Fi gait recognition work, this paper proposes a Wi-Fi-RSMID system for indoor human recognition. By analyzing the channel state information of Wi-Fi signals during human walking, the Wi-Fi-RSMID system extracts key feature information through PCA principal component analysis of thirty subcarriers of CSI. It collects 155 feature points from five principal components of PAC using a method that combines time-frequency domain information, and achieves human recognition through random subspace method. Experiments show that the system can effectively identify the identities of 15 people in different scenarios, with an average recognition rate of about 75.3% - 85.6%.

With the rapid development of the Internet, the scale of the online advertising market has expanded rapidly, and display advertising has become the most popular means of publicity. Accurate advertising recommendation is the guarantee of Internet platform revenue, and accurate advertising click rate prediction is the premise of accurate recommendation and abnormal advertising detection. Therefore, such monitoring and recommendation can be achieved through machine learning combined with artificial intelligence, and the application of intelligent AD recommendation systems and abnormal AD monitoring in the field of machine learning represents a complex integration of technologies to improve the precision and effectiveness of digital marketing strategies. Intelligent AD recommendation systems utilize advanced machine learning algorithms to analyze user behavior and preferences to deliver tailored AD content. These systems leverage vast amounts of user data, including browsing history, purchase history, and engagement metrics, to predict and present the most relevant ads. This paper analyzes the data mining in machine learning algorithms and the real-time online recommendation algorithm of Gaussian process, and analyzes the abnormal advertising monitoring system for maintaining the integrity and efficiency of advertising campaigns. By using machine learning technology for pattern recognition and anomaly detection, various measures and indicators of advertising campaigns can be monitored in a vigilant manner.

The advertising industry is developing very rapidly, especially outdoor advertising, which has attracted people's attention. All kinds of commercial advertisements can be seen everywhere in outdoor public places, but the advertising delivery system on the market is relatively simple in function, and the evaluation of advertising effect lacks effective automatic analysis means, mainly carried out by manual observation, which is low in efficiency and difficult to conduct quantitative evaluation, which directly leads to the lack of targeted advertising. Artificial intelligence advertising refers to the use of artificial intelligence technology (such as voice recognition, face recognition, deep learning, machine learning, etc.), investigation, production, publishing advertising and other fields, the combination of artificial intelligence and advertising brings great value and convenience to people's lives. Among them, the most common algorithm that can achieve accurate and intelligent advertising is NLP, and the artificial intelligence advertising push system based on natural language processing (NLP) algorithm can provide a variety of useful applications in the advertising field. These applications can help advertisers better understand user needs, improve the accuracy and effectiveness of ads, and provide a better user experience. In order to fully tap the advertising information value contained in unstructured data, this paper introduces the text mining technology based on natural language processing, explores from principle to practice, and analyzes the push process and application of intelligent advertisements in daily life by analyzing the implementation steps of NLP algorithm model.

Multichannel Slotted ALOHA Simulator Design for Massive Machine-Type Communication (mMTC) on 5G Network
Authors: Feliana Ferlinda , Harwahyu Ruki , Overbeek Marlinda Vasty
Published: January 2024

Massive Machine-type Communication (mMTC) is one of the main service scenarios in 5G. At the time of initializing the connection to the base station, the MTC machines will make a connection request via the random access procedure. One of the schemes of random access procedure for handling this connection request is similar to how multichannel slotted ALOHA works. Multichannel slotted ALOHA itself is a development of the slotted ALOHA scheme which originally has only a single channel. At the initial state of mMTC, there will be an explosion of the number of demands to the available channels. Given the number of machines that will be connected, the likelihood of a collision on the same channel increases. As a result, the probability of failure also increases. The system's configuration has an impact on the likelihood of success and the time it takes to achieve it. The number of channels influences the likelihood of collisions, the backoff window influences the transmission distribution in each slot, and the maximum transmission limits the ability of device retransmission. These three arrangements have an impact on one another. The simulator build in this research is expected to make it easier for researchers to optimize multichannel slotted ALOHA configurations in 5G to handle the surge in access demands from mMTC devices.
Más allá del afrofuturismo anglosajón. El futurismo caribeño: la Santería en La mucama de Omicunlé de Rita Indiana
Authors: Caruso Maria Cristina
Published: January 2024

El termino Afrofuturismo remite a una etiqueta estético-artística acuñada en la década de los 90 para indicar productos culturales en los que futuros imaginarios hipertecnológicos acogen el triunfal regreso de la identidad africana prediaspórica en un contexto de superación frente a las diferencias raciales. Sin embargo, el término Afrofuturismo no se revela fácilmente adaptable a productos especulativos producidos afuera del marco afroestadounidense. Efectivamente en contextos cronotopológicos diferentes, como el Caribe Hispano, los elementos que remiten a la historia colonial y afro-diaspórica adquieren rasgos originales. Este trabajo propone un análisis descriptivo de la novela La mucama de Omicunlé (2015) de la escritora dominicana Rita Indiana como ejemplo de la corriente especulativo-proyectiva caribefuturista.
Nelson Estupiñán Bass: reposicionando su obra desde el realismo fantástico al afrofuturismo en Ecuador
Authors: Rodrigo-Mendizábal Iván Fernando
Published: January 2024

El artículo sitúa la obra del afroecuatoriano Nelson Estupiñán Bass en el marco de la ciencia ficción y el afrofuturismo. Se considera que, entendiendo su posicionamiento dentro del realismo fantástico con sesgo político, se puede hacer una lectura de su visión del afroecuatorianismo relacionada con la idea de futuro y futurización. Se descubre que es un autor preocupado por la contradicción entre realidad vivida y realidad encumbrada por la tecnociencia: una es la realidad de los oprimidos afrodescendientes y otra la de imaginación futurista moderna. Ello no le impide analizar las ideas sobre los modelos de utopía: si es preferible una utopía que recupere el pasado o la que promete el neoliberalismo, modelos que deberán ser motivo de discusión para la comunidad afro. Así mismo, se constata de su necesidad de innovar la novela con sus propuestas basadas en el materialismo dialéctico para provocar la conciencia crítica del lector.
El imaginario apocalíptico sobre el Conflicto Armado Interno Peruano (1980-2000) en tres cuentos andinos
Authors: Palacios Belinda
Published: January 2024

La literatura apocalíptica judeocristiana estuvo ligada, desde sus orígenes, a periodos de opresión y violencia o de cambio y agitación política y social. Constituyó, asimismo, una forma de resistencia simbólica a las circunstancias de su tiempo, pues revelaba un deseo de cambio radical de las estructuras existentes, bajo la convicción de que sólo un cataclismo cósmico podría alterar el orden del mundo y traer justicia (Focant, 2010; Weber, 1999: 35-51). Partiendo de este principio, nuestro artículo propone abordar una serie de cuentos que, en nuestra opinión, recurren a un imaginario apocalíptico (muchas veces enriquecido por elementos propios del imaginario andino) para recrear y describir el periodo del Conflicto Armado Interno peruano (1980-2000). Estos son “La guerra del arcángel san Gabriel”, de Dante Castro, “¡Pacha Tikra!”, de Walter Lingán y “Como cuando estábamos vivos”, de Luis Nieto Degregori. Nuestro propósito reside en revelar el sentido que se le da al Apocalipsis en cada uno de los textos, pues es ahí donde anida su potencial político y de reescritura de la historia, y donde mejor puede percibirse la interpretación personal del conflicto que vehicula cada autor.
Antonio Palacios, el movimiento travesti de Querétaro (México) en los años setenta y la visibilización pionera de masculinidades no hegemónicas
Authors: García Sánchez Raúl
Published: January 2024

El presente artículo surge al observar que, en gran medida, los estudios de género en el Estado de Querétaro, México, se han enfocado en los acontecimientos posteriores a la globalización, pero se ha investigado muy poco en relación con los años previos. Por ello, partiendo del método etnográfico, se realizaron varias entrevistas a Antonio Palacios, sobreviviente del movimiento travesti que impulsó, a finales de los años setenta, la visibilización y el reconocimiento civil de la homosexualidad masculina en la ciudad. Con la información proporcionada por Palacios, se realizó trabajo hemerográfico en el Archivo Histórico del Estado de Querétaro, para corroborar con notas periodísticas las tensiones que surgieron cuando el bar y antiguo prostíbulo La Iguana obtuvo la primera licencia del gobierno para funcionar como lugar de reunión gay. Se puede demostrar, de ese modo, que no solo en Querétaro, sino en gran parte de México, el movimiento travesti de los años setenta cimentó las bases de las luchas sociales alrededor de las masculinidades no hegemónicas, situación invisibilizada porque formaban parte del bloque posabismal, y eran relegados por cuestiones de clase. Este trabajo pretende abordar el movimiento travesti de esos años y destacar sus aportes a las generaciones queer posglobalización.
La emergencia de las identidades travestis en la cultura argentina
Authors: Insausti Santiago Joaquín
Published: January 2024

La investigación reconstruye las condiciones de emergencia de los modos de vida travestis entre las décadas de 1950 y 1980. La hipótesis principal será que tanto lo travesti como lo gay son producciones contemporáneas que tuvieron su génesis en las culturas maricas de antaño a través de un proceso de diferenciación mutua. Este proceso requirió como condición de posibilidad la escisión de la identidad sexual y de la identidad de género —antes indisociablemente imbricadas— como dos dimensiones independientes y autónomas. El trabajo recorrerá las transformaciones en la sexualidad y en los usos del género de maricas y travestis. Se analizará como la incorporación de saberes y prácticas sobre la manipulación del cuerpo y la impostación de la feminidad en carnavales y cabarets abrieron un espacio de posibilidad para la emergencia de la experiencia travesti contemporánea. Sostendré que el surgimiento de lo travesti es paralelo a la emergencia de las identidades gais a partir de un proceso simultáneo de diferenciación transfóbico que requirió la negación y el repudio de las travestis por parte de estos últimos. La investigación se basa en el análisis historiográfico de un corpus diverso de materiales culturales, hemerográficos y testimoniales.
Restos, rastros y memorias: 'El invencible verano de Liliana', de Cristina Rivera Garza
Authors: Maldonado Escoto Nely E.
Published: January 2024

Este artículo pretende analizar cómo Cristina Rivera Garza construye memoria sobre el feminicidio de su hermana en El invencible verano de Liliana (2021). Se parte de observar que, al realizar un trabajo profundo con las memorias desde el presente, los marcos culturales desde los que se reconfiguran las experiencias pasadas proveen las herramientas y el lenguaje que inciden en la forma en que se rememora. En este sentido, el lenguaje y la perspectiva que aportan a Rivera Garza los feminismos tanto teóricos como activistas, detonan un tipo de mirada que activa las memorias desde otra situacionalidad. Se postula entonces que el recorrido que Rivera Garza realiza vincula las labores de investigación y montaje con la puesta en movimiento de afectos y recuerdos, configurando así un archivo otro, un mapa-plano móvil y multidimensional que traza conexiones desde el pasado hasta el presente. A través de este archivo, es posible reflexionar sobre el pasado con herramientas actuales y construir así una memoria dinámica que interpela a sus lectores, activándoles también. El dinamismo por el que apuesta, desde una obra difícilmente encasillable en un género en particular, es parte de su dimensión política.
Hacia una nueva conceptualización de la narrativa sobre el indígena: del neoindigenismo al postindigenismo
Authors: Alemany Bay Carmen
Published: January 2024

Dada la evolución que ha sufrido la narrativa y, asimismo, la situación de los indígenas, y cómo este aparece en las historias noveladas, es el momento de pensar un término que se adecúe a las recientes expresiones literarias sobre esta temática. Una nueva nomenclatura, el postindigenismo, que supondría el relevo de la llamada narrativa neoindigenista; término que se aplicó a las novelas y relatos que sobre el indígena se publicaron en la década de los sesenta y parte de los setenta, y que tuvieron como precedente las narrativas sobre el indígena en los años cuarenta. Para comprender en toda su dimensión lo que supone esta nueva nomenclatura, nos centraremos en las conquistas recientes de los indígenas en América Latina, el paso del indianismo al indigenismo narrativo y de este al postindigenismo, sus características y sus peculiaridades, así como sus relaciones y diferencias con los anteriores movimientos. Cerraré esta cuestión con la ciencia ficción latinoamericana y la cuestión del indígena.

Theoretical computational models are widely used to describe latent cognitive processes. However, these models do not equally explain data across participants, with some individuals showing a bigger predictive gap than others. In the current study, we examined the use of theory-independent models, specifically recurrent neural networks (RNN), to classify the source of a predictive gap in the observed data of a single individual. This approach aims to identify whether the low predictability of behavioral data is mainly due to noisy decision-making or miss-specification of the theoretical model. First, we used computer simulation in the context of reinforcement learning to demonstrate that RNNs can be used to identify model miss-specification in simulated agents with varying degrees of behavioral noise. Specifically, both prediction performance and the number of RNN training epochs (i.e., the point of early stopping) can be used to estimate the amount of stochasticity in the data. Second, we applied our approach to an empirical dataset where the actions of low IQ participants, compared with high IQ participants, showed lower predictability by a well-known theoretical model (i.e., Daw’s hybrid model for the two-step task). Both the predictive gap and the point of early stopping of the RNN suggested that model miss-specification is similar across individuals. This led us to a provisional conclusion that low IQ subjects are mostly noisier compared to their high IQ peers, rather than being more miss-specified by the theoretical model. We discuss the implications and limitations of this approach, considering the growing literature in both theoretical and data-driven computational modeling in decision-making science.

Окаменелое дерево относится к группе флорогенных ювелирно-поделочных материалов и широко используется для изготовления разнообразных видов изделий. В статье впервые приведены результаты детального геммологического, минерального и геохимического изучения образцов окаменелого дерева ювелирно-поделочного качества с о. Сахалин из сантонских и кампанских отложений верхнего мела. По минеральному составу, декоративным и технологическим характеристикам выделяется два типа образцов. В первом типе исходный органический состав древесины практически полностью замещен кварцем и в меньшем количестве кальцитом с включениями пирита, доломита, микроклина и каолинита. Во втором типе существенно возрастает роль кальцита и снижается содержание кварца. Фрагменты окаменелого дерева имеют большие размеры, положительные декоративные, технологические, экологические характеристики. Оно может собираться в руслах рек с другими видами ювелирно-поделочных материалов без значительных материальных затрат и без нарушения сохранности окружающей среды.
Дорога ветров вдоль монгольских степей, "Природа"

Древнюю Монголию обычно представляют страной динозавров и другой мезозойской фауны и флоры. Однако еще совместные советско-монгольские экспедиции прошлого века показали, что докембрийские и палеозойские толщи этой страны содержат не менее интересные палеонтологические остатки и седиментологические свидетельства, важные для понимания развития всей Земли. Особый интерес для многочисленных ныне международных экспедиций представляет интервал геологического времени от 1 млрд до 500 млн лет назад, вместивший бурное развитие одноклеточных эукариот, всепланетные оледенения, один из главных этапов фосфатонакопления и становление животных с минеральным скелетом. Тем более что территория Монголии в те времена представляла собой не единый морской бассейн, а множество морей, приуроченных к разным микроконтинентам и вулканическим дугам, что позволяет понять, чем последовательность событий отличалась в разных обстановках.

Африканский баобаб — крайне неприхотливое, обладающее множеством полезных свойств дерево. Его различные части употребляются в пищу, используются в медицине и в изготовлении необходимых в хозяйстве изделий, поэтому баобабы имеют огромное значение для населения засушливых территорий. По какой причине баобабы могут выдерживать экстремальные засухи, расти на неблагоприятных почвах, быстро восстанавливаться от повреждений и доживать до 2 тыс. лет и более Ответ на эти вопросы кроется в особенностях внутреннего строения дерева: по мере роста внутри баобаба появляются новые «стволы». Такое явление наблюдается только у деревьев рода Adansonia. Для того чтобы разобраться, как изменяется структура баобаба с его возрастом и как это влияет на его рост и продолжительность жизни, мы отправились на северо-восток Южно-Африканской Республики, в провинцию Лимпопо, туда, где начинается ареал африканского баобаба.

На примере выращенных твердых растворов GaInAsP и GaInAsSbBi на подложках GaP с кристаллографической ориентацией (111) изучены особенности импульсного лазерного напыления многокомпонентных твердых растворов на основе соединений III–V групп. Твердые растворы выбраны исходя из обозначенных трудностей при выращивании методом импульсного лазерного напыления в связи с тем, что состоят из двух металлов III группы и трех легколетучих металлоидов V группы. Вследствие актуальности их практического использования для выращивания оптоэлектронных гетероструктур методами рентгеновского энергодисперсионного микроанализа, сканирующей электронной микроскопии и рамановского рассеяния проведен анализ состава твердых растворов и их морфологии. Экспериментально показано, что комбинирование лазерного флюенса и добавления в состав поверхностно-активных элементов, таких как Bi или Sb, позволяет снизить плотность капель на поверхности выращенной пленки на три порядка, а их средний размер уменьшить с 300 до 45 нм. Методом рентгеновского энергодисперсионного микроанализа определено, что капли состоят из индия. Основными причинами нарушения стехиометрии являются капли In и частичная десорбция элементов V группы. Установлено, что источником капель In являются образование жидкой фракции In на поверхности мишени при распылении с флюенсом 2,3 Дж/см2 и высокая поверхностная диффузия In из объема слоя на поверхность. Введение поверхностно-активных элементов в состав твердого раствора приводит к предотвращению десорбции легколетучих элементов V группы, например мышьяка. Повышением лазерного флюенса и подбором состава твердого раствора можно улучшать морфологию тонких пленок, выращенных методом импульсного лазерного напыления.
К экспериментальным доказательствам магниторецепции у серых тюленей Halichoerus grypus atlantica Nehring, 1886 , "Наука юга России"

Совокупность современных данных магнитобиологии позволяет говорить о том, что биологическое действие весьма слабых магнитных полей как искусственного происхождения, так и связанных с солнечной и геомагнитной активностью, является реальностью. Магниторецепция, то есть восприятие магнитных полей, как предполагается, играет важную роль для ориентации и навигации у некоторых наземных и водных животных. Многие морские млекопитающие, как китообразные, так и ластоногие, совершают длительные миграции на большие расстояния. И если использование магниторецепции китообразными широко обсуждается в научном сообществе, то исследования, посвященные восприятию магнитных полей ластоногими, практически отсутствуют. Для изучения магниточувствительности у ластоногих мы сконструировали экспериментальный стенд на основе системы колец Гельмгольца. Объект исследования три половозрелые самки серого тюленя Halichoerus grypus atlantica. С помощью метода инструментальных условных рефлексов и методики выбора объекта по заданным характеристикам мы обучили тюленей выбирать из двух или трех идентичных катушек Гельмгольца ту, в которой на данный момент генерировалось магнитное поле. В результате проведенных экспериментальных исследований нами было установлено, что искусственное магнитное поле частотой 8, 20 и 36 Гц с индукцией 110 130 мкТл является для серых тюленей воспринимаемым стимулом, на предъявление которого был выработан условный рефлекс. Средняя доля верных ответов превышала 79 % во всех контрольных испытаниях. Полученные данные позволяют утверждать, что серые тюлени обладают магниторецепцией.
