Habituation to thaxtomin A increases resistance to common scab in ‘Russet Burbank’ potato
Authors: Beaudoin Nathalie , Isayenka Iauhenia , Ducharme Audrey , Massie Sophie , Gagnon André , Hogue Richard , Beaulieu Carole , Michaud Dominique
Published: June 2021

Common scab is a potato disease characterized by the formation of scab-like lesions on the surface of potato tubers. The actinobacterium Streptomyces scabiei is the main causal agent of common scab. During infection, this bacterium synthesizes the phytotoxin thaxtomin A which is essential for the production of disease symptoms. While thaxtomin A can activate an atypical programmed cell death in plant cell suspensions, it is possible to gradually habituate plant cells to thaxtomin A to provide resistance to lethal phytotoxin concentrations. Potato ‘Russet Burbank’ calli were habituated to thaxtomin A to regenerate the somaclone RB9 that produced tubers more resistant to common scab than those obtained from the original cultivar. Compared to the Russet Burbank cultivar, somaclone RB9 generated up to 22% more marketable tubers with an infected tuber area below the 5% threshold. Enhanced resistance was maintained over at least two years of cultivation in the field. However, average size of tubers was significantly reduced in somaclone RB9 compared to the parent cultivar. Small RB9 tubers had a thicker phellem than Russet Burbank tubers, which may contribute to improving resistance to common scab. These results show that thaxtomin A-habituation in potato is efficient to produce somaclones with increased and durable resistance to common scab.

Los SIG: nuevas herramientas para el estudio de los espacios paleolíticos
Authors: Ortega Martínez Paula
Published: June 2021

El hombre, como individuo y como grupo, tiene una concepción del lugarque habita. Este enfoque, permite interpretar la forma de vida de las sociedades en contextos espaciales significativos. No se puede aislar las sociedades paleolíticas del espacio que dominaban y del que se apropian para el desarrollo de sus labores cotidianas. Los suelos dehabitación constituyen un testimonio latente de las formas de vida del hombre paleolítico, del que pocos datos se conservan, salvo aquellos que se derivan de la excavación de yacimientos y del estudio del arte conservado, ambos reflejo de las actividades desarrolladas enel espacio doméstico.Los patrones habitacionales tienen que ser comprendidos en términos de relaciones espaciales que los materiales entablan entre si, en un marco genérico, el nivel de ocupación. Para este estudio contamos con los Sistemas de Información Geográfica, herramientas indispensablespara la gestión de los datos principalmente espaciales, pero también funcionales o tecnológicos.
La muerte en la Arqueología: visiones cruzadas / posiciones encontradas
Authors: Sánchez Polo Alejandra
Published: June 2021

La muerte, las necrópolis, los objetos enterrados junto a los difuntos constituyeron un reclamo para los primeros arqueólogos que con un indudable –pero ciertamente escaso– interés científico desenterraron estos preciados tesoros de innumerables yacimientosarqueológicos desde hace ya dos siglos. Progresivamente se ha ido abandonando esta posición anticuarista –sin duda, muy peligrosa para el desarrollo positivo de nuestra disciplina para adoptar otros marcos de referencia que no primaran el objeto en sí mismo sino a la sociedad que lo produjo. En la presente comunicación se abordarán las posiciones teóricas que a lo largo del siglo XX han marcado hitos en la historiografía, tomando ejemplos de importantes yacimientos excavados, haciendo especial hincapié en cómo el interés científicode cada época se centra en aspectos específicos. Para finalizar, se realizará un avance de las posiciones más vanguardistas, exploradoras de horizontes que recalan en la racionalidad de las gentes del pasado.
Escribir literatura polemológica en Roma
Authors: Paniagua Aguilar David
Published: June 2021

Una formulación ya clásica de Giuffrè afirma que “el ejército como fundamento principal del Imperio romano es un dato fuera de discusión”. Esta centralidad del ejército y de la dimensión militar también fue percibida como tal por los propios Romanos y prueba de ello fue la reflexión por escrito acerca de la res militaris, unas veces —las más— de tenor más práctico, otras más teórico. El continuo cultivo de esta materia constituyó un auténtico género literario con su propia tradición dentro de la literatura técnica. En lo sustancialesta tradición es poco conocida en sus detalles y apenas se ha ofrecido un cuadro panorámico y diacrónico de ella. Este el objeto de estas páginas, ofrecer un recorrido por los diferentes puntos que conforman la tradición polemográfica latina con una descripciónde sus características más notables.
Apropiaciones de la Antigüedad. Legitimación del poder y transmisión de un mito
Authors: Carbó García Juan Ramón
Published: June 2021

Se aborda en estas páginas la presentación del proyecto de investigación desarrollado en torno a la percepción de la Antigüedad y las apropiaciones de ésta realizadas a lo largo de las diferentes edades históricas en varios países y territorios europeos, pero especialmente en España y en Rumanía, para el caso específico planteado de la apropiación de la historia antigua rumana. Mediante el análisis de la historiografía rumana en relación con el nacionalismo en este país, y con el estudio del mito gético –en torno a la confusión e identificación entre los godos y los antiguos pobladores de Rumanía, los getas o dacios– y su transmisión en las genealogías míticas europeas desde la propia Antigüedad hasta nuestrosdías, la investigación pretende constatar con ese ejemplo el gran poder de legitimación y justificación del pretérito, y especialmente del más antiguo, en diferentes momentos y circunstancias nacionales.
Anarcosindicalismo, resistencia y grupos de afinidad. La comisión de propaganda confederal anarquista (1937-1939)
Authors: Martín Nieto Isaac
Published: June 2021

Durante la Guerra Civil española (1936-1939), casi todos los miembrosde los comités dirigentes de la Confederación Nacional del Trabajo (CNT) y de la Federación Anarquista Ibérica (FAI) militaban en algún grupo de afinidad, institución específicamente anarquista que permitía a sus miembros forjar esferas de influencia propias al otorgarles una disciplina interna y unas aspiraciones políticas comunes.Considerando que, a pesar de ello, la historiografía aún no ha integrado el análisis de las dinámicas grupales en el estudio del anarcosindicalismo, este trabajo pretende, además de destacar la potencialidad del nuevo enfoque interpretativo, demostrar la importancia de las relaciones de afinidad anarquista para explicar la fractura del apoyo libertario a la política de resistencia impulsada por el Gobierno de la República en guerra del doctor Negrín (1937-1939), centrando el análisis en las dialécticas de poder desatadas en torno a la Comisión de Propaganda Confederal y Anarquista del Centro.
Reviewing the Pertinence of Sentinel-1 SAR for Urban Land Use Land Cover Classification
Authors: Abudu Dan , Parvin Nigar Sultana , Andogah Geoffrey
Published: June 2021

Conventional approaches for urban land use land cover classification and quantification of land use changes have often relied on the ground surveys and urban censuses of urban surface properties. Advent of Remote Sensing technology supporting metric to centimetric spatial resolutions with simultaneous wide coverage, significantly reduced huge operational costs previously encountered using ground surveys. Weather, sensor’s spatial resolution and the complex compositions of urban areas comprising concrete, metallic, water, bare- and vegetation-covers, limits Remote Sensing ability to accurately discriminate urban features. The launch of Sentinel-1 Synthetic Aperture Radar, which operates at metric resolution and microwave frequencies evades the weather limitations and has been reported to accurately quantify urban compositions. This paper assessed the feasibility of Sentinel-1 SAR data for urban land use land cover classification by reviewing research papers that utilised these data. The review found that since 2014, 11 studies have specifically utilised the datasets.
Choose Your Own Adventure: Gamified Course Design in History of Science
Authors: Stewart John , Sheppard Kathleen
Published: June 2021

To combat high dropout rates and low motivation for online courses, we gamified a history of science course. To do so, we used an online educational program called 3DGameLab to convert what had been a well-liked face-to-face lecture and discussion course to an online format, for the purposes of long-distance teaching and learning. Within 3DGameLab, we prepared approximately three times as much content as would be taught in a face-to-face class. Clear tasks and immediate rewards in the form of experience points (XP) contributed to a transparent motivational system as compared to traditional grading. In this course, students completed their assignments asynchronously. Sustaining engagement is challenging in this format due to student self-management, but, with the game mode, students could repeat their attempts to pass a quest (a lesson) until they succeed (submit a passable response). The feedback cycle was short, and we found that students tend to persevere in the face of failure when they get rapid feedback, rather than quit. To test the adaptability of the asynchronous, gamified format, we also designed this course as a hybrid course. Students remained engaged when the feedback was quick, and the tasks were clearly set. We did not perform a quantitative study; the purpose of this article is to share a design study of our methods and subsequent experience with these modalities.
Innovative Transport Pressure Management Models for Efficient Transportation Management in the RUDN-University
Authors: Redina Margarita , Savenkova Elena , Khaustov Aleksandr , Silaeva Polina
Published: June 2021

The main transport flows on the RUDN territory are caused by the city public and private transport. The general transportation scheme around and through the campus develops some decades. Today this is a huge traffic system with high technogenic pressure on the surrounding ecosystems. The efforts of the university only on the organization of bike transport and shuttle buses cannot protect in this situation our territory. Thus, the university in collaboration with the Moscow government try to solve the transportation problem: a new underground station named RUDN will be built – this must help to optimize transport flows. Transportation management in the university campus (especially situated in the city) needs to apply reliable models for the optimization of transport pressure. That is why, for the RUDNUniversity campus in the South-West of Moscow, we try to develop the most sensitive indicators and to control a set of technogenic factors affecting environmental quality. The unique environmental monitoring system of the RUDN campus able to evaluate the environmental state of the territory and to contribute to maintaining the environmental quality is now under development. The primary results were presented in September 2019 during the first UI Green Metric World Sustainable Campuses Tour in RUDN.

Authors: Utama Yos Johan , Ambariyanto Ambariyanto
Published: June 2021

As a higher education institution with a vision to become a research university, programs and activities related to research are Universitas Diponegoro main concern. Research is one of the three main pillars of higher education in Indonesia, apart from education and community service. Besides that, as a state university, its development is also influenced by central government policies. Currently, Undip is a state university with legal status and has wide autonomy. This paper explains research programs, activities and challenges that still need to be addressed in the future. To increase research capacity at Diponegoro University, there are five main programs, namely: 1. Increasing the capacity of human resources; 2. Improvement of facilities and supporting facilities; 3. Increasing the availability of research funds, 4. Collaboration and 5. Creating a conducive environment to research development at universities. Based on the application of the five programs, there has been a substantial increase in a research capacity, especially when viewed from indicators of international scientific publications, and an increase in the number of patents obtained. But there are still many challenges that need to be overcome, including the increase in the citation of published papers and the utilization of patent by industries.

Fridays for Future in der Corona-Krise
Authors: Hunger Sophia , Hutter Swen
Published: June 2021

Die Corona-Krise hat Fridays for Future (FFF) – wie auch andere soziale Bewegungen – mit nicht absehbaren und einschneidenden Einschränkungen konfrontiert. Inwiefern kam es aufgrund dieser radikal veränderten Situation zu einer Anpassung des Handlungsrepertoires von FFF? Und ermöglichen online bzw. hybride Protestaktionen eine Ausweitung des Mobilisierungspotentials durch die Einbindung von geographischen Einheiten, die bisher nicht an die Bewegung angeschlossen waren? Diesen Fragen nähern wir uns in diesem Beitrag mittels neuer online-generierter Datenquellen. Dabei greifen wir auf Informationen zu den Teilnehmer*innen und Protestformen des Online-Streiks vom 24. April und des Klimastreiks vom 25. September 2020 zurück. Unsere deskriptiven Analysen zeigen regionale Varianzen in der Protestintensität und Innovationen in den Protestformen. Darauf aufbauend nutzen wir die geographisch kleinteilige Struktur der Daten, um in Regressionsanalysen etablierte Erklärungsfaktoren für die Mobilisierungskraft von FFF zu testen. Generell weisen die Ergebnisse auf keine deutliche Erweiterung der Mobilisierung hin: FFF konnte während der Pandemie besonders stark in urbanen, grün wählenden Gebieten mit hohem Bildungsniveau und Frauenanteil in Bevölkerung und Politik mobilisieren.

Adolescence as a “critical period” in the heritage language use. Polish in Germany
Authors: Pułaczewska Hanna
Published: June 2021

In the article, we consider the impact of adolescence upon the usage of Polish in Polish-German bilinguals raised and living in Germany and demonstrate how adolescence surfaces as a socially based “critical period” in this usage using results from a survey and interviews conducted with 30 teenagers. In the quantitative part of the study, we seek to establish whether adolescents’ age affected the pattern and quantity of their usage of Polish in the media and contacts with age peers, whether the latter two facets of growing up with Polish were interrelated, and which other factors affected peer-relevant activities in Polish. Both age and peer contact turned out to significantly affect the use of the media in Polish, while peer contact in Polish was affected by the parental use of Polish in parent-child communication. The qualitative part presents the context and motivation for using Polish by the youths in peer-relevant activities. We integrate the results with insights provided by child development psychology from the perspective of language socialisation theory and interpret the age-related decline of interest in the Polish media as an effect of a diminishing role of parents and the increasing role of age peers as role models in personal development.
El marcador conversacional ahre en memes: hacia la definición del marcador-meme en interacciones digitales de dos comunidades de práctica juveniles
Authors: De Luca Natalia
Published: June 2021

El presente artículo busca describir y analizar, desde un enfoque multimodal (Kress y van Leeuwen, 2001; Kress, 2005, 2009; Jewitt, 2009), las relaciones entre los marcadores del discurso (Martín Zorraquino y Portolés, 1999) y los memes (Knobel y Lankshear, 2005; Varis y Blommaert, 2015), a partir de una selección de memes que fueron compartidos en dos grupos de Whatsapp de estudiantes de dos escuelas secundarias de Buenos Aires. Para ilustrar esta relación, nos detendremos en el marcador ahre, marcador de gran frecuencia de uso en el habla de los estudiantes, con el fin de, en primer lugar, describir las funciones comunicativas que mantiene en los memes, y, en segundo lugar, indagar en qué medida este marcador desempeña solo una función discursiva verbal dentro del meme, o si se configura de manera autónoma como marcador-meme. Esta categoría novedosa y aporte de esta investigación nos permitirá evidenciar cómo un marcador oral puede constituirse en meme y, simultáneamente, cómo un meme puede funcionar como marcador en los intercambios en línea. Por último, discutiremos los resultados en torno al modal ontinuum (Tannen, 1982), y cómo los marcadores conversacionales en géneros digitales se inscriben como un recurso dentro del repertorio lingüístico de los estudiantes.
Kinetic and Kinematic Analysis of Various Drop Jump Performances in Army Reserve Officer Training Corps Cadets

Merrigan, JJ, O'Toole, KB, Wutzke, CJ, and Jones, MT. Kinetic and kinematic analysis of various drop jump performances in army reserve officer training corps cadets. J Strength Cond Res 36(3): 738–746, 2022—The purpose was to examine effects of sex, drop height, and external loads on drop jump mechanics in Reserve Officer Training Corps cadets and whether findings were associated with strength. Males (n = 14) and females (n = 12) completed maximal isokinetic concentric (slow-C and fast-C) and eccentric (slow-E and fast-E) knee extensions and flexions at 60°·s−1 and 180°·s−1. After 72 hours, 3 drop jumps were performed under 3 conditions (i.e., 30 cm unloaded [30UL], 30 cm loaded 15 kg [30L], and 60 cm unloaded [60UL]). No sex × condition interactions existed for any metric (p > 0.05). The 30L condition resulted in slower eccentric and concentric center of mass (COM) and angular velocities, reduced concentric vertical ground reaction forces (vGRF), and lower jump performances. Although 60UL resulted in greater eccentric COM and angular velocities, peak vGRF, impulse, and rate of force development (p < 0.008), no differences existed in jump performances. Males had faster COM and angular concentric velocities and smaller knee valgus angles, but no different vGRF compared with females. The change in the peak hip angle, because of 60UL, was associated with knee extension eccentric and concentric strength, whereas changes in knee angles were associated with eccentric strength. Likewise, eccentric strength influenced the effects of 30L on landing vGRF more so than concentric strength. Initial strength training is recommended, specifically emphasizing eccentric actions, before performing loaded (15 kg) drop jumps to reduce the increase of landing forces. However, caution may be required when performing drops from 60 cm because of increased forces, although no decline in jump performances were noted.

Stone, MH, Hornsby, WG, Haff, GG, Fry, AC, Suarez, DG, Liu, J, Gonzalez-Rave, JM, and Pierce, KC. Periodization and block periodization in sports: emphasis on strength-power training—a provocative and challenging narrative. J Strength Cond Res 35(8): 2351–2371, 2021—Periodization can be defined as a logical sequential, phasic method of manipulating fitness and recovery phases to increase the potential for achieving specific performance goals while minimizing the potential for nonfunctional over-reaching, overtraining, and injury. Periodization deals with the micromanagement of timelines and fitness phases and is cyclic in nature. On the other hand, programming deals with the micromanagement of the training process and deals with exercise selection, volume, intensity, etc. Evidence indicates that a periodized training process coupled with appropriate programming can produce superior athletic enhancement compared with nonperiodized process. There are 2 models of periodization, traditional and block. Traditional can take different forms (i.e., reverse). Block periodization has 2 subtypes, single goal or factor (individual sports) and multiple goals or factors (team sports). Both models have strengths and weaknesses but can be “tailored” through creative programming to produce excellent results for specific sports.
Gonadotropin-Releasing Hormone (GnRH) Neuron Potassium Currents and Excitability in Both Sexes Exhibit Minimal Changes upon Removal of Negative Feedback
Authors: DeFazio R. Anthony , Moenter Suzanne M.
Published: June 2021

Gonadotropin-releasing hormone (GnRH) drives pituitary secretion of luteinizing hormone and follicle-stimulating hormone, which in turn regulate gonadal functions including steroidogenesis. The pattern of GnRH release and thus fertility depend on gonadal steroid feedback. Under homeostatic (negative) feedback conditions, removal of the gonads from either females or males increases the amplitude and frequency of GnRH release and alters the long-term firing pattern of these neurons in brain slices. The neurobiological mechanisms intrinsic to GnRH neurons that are altered by homeostatic feedback are not well studied and have not been compared between sexes. During estradiol-positive feedback, which is unique to females, there are correlated changes in voltage-gated potassium currents and neuronal excitability. We thus hypothesized that these same mechanisms would be engaged in homeostatic negative feedback. Voltage-gated potassium channels play a direct role in setting excitability and action potential properties. Whole-cell patch-clamp recordings of GFP-identified GnRH neurons in brain slices from sham-operated and castrated adult female and male mice were made to assess fast and slow inactivating potassium currents as well as action potential properties. Surprisingly, no changes were observed among groups in most potassium current properties, input resistance, or capacitance, and this was reflected in a lack of differences in excitability and specific action potential properties. These results support the concept that, in contrast to positive feedback, steroid-negative feedback regulation of GnRH neurons in both sexes is likely conveyed to GnRH neurons via mechanisms that do not induce major changes in the biophysical properties of these cells.

Nitrous oxide (N2O) is a hypnotic gas with antidepressant and psychedelic properties at subanesthetic concentrations. Despite long-standing clinical use, there is insufficient understanding of its effect on neural dynamics and cortical processing, which is important for mechanistic understanding of its therapeutic effects. We administered subanesthetic (70%), inhaled N2O and studied the dynamic changes of spiking rate, spectral content, and somatosensory information representation in primary motor cortex (M1) in two male rhesus macaques implanted with Utah microelectrode arrays in the hand area of M1. The average sorted multiunit spiking rate in M1 increased from 8.1 ± 0.99 to 10.6 ± 1.3 Hz in Monkey W (p < 0.001) and from 5.6 ± 0.87 to 7.0 ± 1.1 Hz in Monkey N (p = 0.003). Power spectral densities increased in beta- and gamma-band power. To evaluate somatosensory content in M1 as a surrogate of information transfer, fingers were lightly brushed and classified using a naive Bayes classifier. In both monkeys, the proportion of correctly classified fingers dropped from 0.50 ± 0.06 before N2O inhalation to 0.34 ± 0.03 during N2O inhalation (p = 0.018), although some fingers continued to be correctly classified (p = 0.005). The decrease in correct classifications corresponded to decreased modulation depth for the population (p = 0.005) and fewer modulated units (p = 0.046). However, the increased single-unit firing rate was not correlated with its modulation depth (R2< 0.001,p = 0.93). These data suggest that N2O degrades information transfer, although no clear relationship was found between neuronal tuning and N2O-induced changes in firing rate.

Published: June 2021

New information is rarely learned in isolation; instead, most of what we experience can be incorporated into or uses previous knowledge networks in some form. Previous knowledge in form of a cognitive map can facilitate knowledge acquisition and will influence how we learn new spatial information. Here, we developed a new spatial navigation task where food locations are learned in a large, gangway maze to test how mice learn a large spatial map over a longer time period—the HexMaze. Analyzing performance across sessions as well as on specific trials, we can show simple memory effects as well as multiple effects of previous knowledge of the map accelerating both online learning and performance increases over offline periods when incorporating new information. We could identify the following three main phases: (1) learning the initial goal location; (2) faster learning after 2 weeks when learning a new goal location; and then (3) the ability to express one-session learning, leading to long-term memory effect after 12 weeks. Importantly, we are the first to show that buildup of a spatial map is dependent on how much time passes, not how often the animal is trained.

The investigation emerged from the diverse opinions existing among BEIC-ELCL actors regarding the pertinence of interaction, partial immersion and experiential learning communicative principies for the teaching of English to children in Costa Rica. Thus, whereas BEIC curriculum designers and professors considered these principies to be highly effective, many student-teachers in that program believe just the opposite.
Nell’occhio di María Zambrano: tra immagine pittorica e ragione poetica
Authors: Parente Lucia Maria Garzia
Published: June 2021

L’esperienza estetica di María Zambrano è articolata intorno ad un centro di valori sensibili dell’uomo. Valori che gli permettono di sentire costantemente la necessità ed il desiderio di andare oltre, di guardare in altro modo la semplice fruizione artistica e, così, tendere verso quel nucleo etico incarnato nella sua stessa esistenza: della sua esistenza unica del e nel cosmo.

Vogliamo centrare la nostra riflessione su alcuni dettagli della sua produzione estetica, che denota una rara sensibilità filosofica nel deserto desolato della barbarie del xx secolo, per identificare quell’incanto speciale dello sguardo zambraniano orientato alla bellezza: unica possibilità per l’essere umano di non perdersi nei meandri dell’oscurità del mondo e, in molti casi, della sua anima.
Los clowns de María Zambrano y la Generación del 27
Authors: Gutiérrez Bracho Carlos
Published: June 2021

En “El payaso y la filosofía”, María Zambrano reflexiona sobre la actuación de uno de los artistas clown más importantes del siglo XX, en Europa: Grock. En este texto, encuentra una similitud entre el filósofo y el payaso. Aunque se trata de un tema poco recurrente en la obra de esta pensadora, la vincula a los intelectuales de la Generación del 27, que dio lugar a “una nueva edad de oro” en la literatura española, porque algunos de sus miembros mostraron alto interés por los clowns, entre ellos Federico García Lorca, León Felipe y Rafael Alberti, así como algunos de los que pertenecieron a la llamada “otra” generación del 27, como Ramón Gómez de la Serna. Así, este trabajo trata sobre cómo, en un tiempo anterior a la Guerra Civil española, estos intelectuales encontraron, en la figura cómica, oportunidad para hablar de la lucha por la libertad y de una nueva dimensión de la experiencia humana.

Contra la tesis de Villey según la cual la sola presencia del derecho subjetivo es indicio de nominalismo (lo que haría nominalista al conjunto de la segunda escolástica), se sostiene que la relación de los teólogos-juristas españoles del XVI y XVII con la modernidad no es unívoca. Se muestra la figura de Francisco Suárez como ejemplar de las tensiones internas propias de una teoría jurídica que, aún tomista en algunos aspectos, integra elementos contradictorios, que le llevan a exaltar el derecho subjetivo como la realidad jurídica primordial, eclipsando, así, el lugar de lo justo y redefiniendo la ley.
Escolástica renacentista y recepción de la doctrina aristotélica sobre lo justo natural: Philipp Melanchthon y Francisco Suárez
Authors: Herreros Besa Alfonso , Contreras Aguirre Sebastián
Published: June 2021

La interpretación escolástica de Aristóteles se concentra en la idea del derecho natural para justificar los fundamentos prepolíticos de la realidad social. Ahora bien, no existe una sola gran síntesis escolástica, ni hay tampoco un único aristotelismo que sea común a todos los comentadores escolásticos de la Ethica ? 7. De ese modo, Philipp Melanchthon (1497-1560), el llamado præceptor Germaniæ, expone un Aristóteles distinto del que comenta el jesuita Francisco Suárez (1548-1617), porque, como se verá a continuación, mientras que Suárez entiende lo justo por naturaleza como el derecho de la razón práctica, Melanchthon lo identifica con el conocimiento teórico de los principios morales impresos por Dios en el hombre.
Tecno-especies: la humanidad que se hace a sí misma y los desechables
Authors: G. Navarro María , Kovacic Mateja
Published: June 2021

La cultura popular sigue alimentando el imaginario colectivo con cosas, humanas y no humanas, en las que podríamos convertirnos o con las que podríamos vernos confrontados. Además de robots, otras figuras significativas de la ficción popular que generaron imágenes son los seres humanos no humanos y los ciborgs, incorporadas a realidades socioculturales históricamente diversas. Los robots y la inteligencia artificial están redefiniendo el orden natural y su estructura jerárquica. No es raro, pues el orden natural siempre fluye, moldeado por los nuevos descubrimientos científicos, en especial la lectura del código genético, que revela y redefine las relaciones entre las formas de vida. Sin embargo, por primera vez, se está introduciendo una nueva especie artificial en los esquemas existentes y, por primera vez, parece hibridar el orden mundial natural antropocéntrico.
Values, goals and benefits of university research: The Public health perspective
Authors: Luarsabishvili Vladimer , Kiladze Maia
Published: June 2021

Public health as a healthcare system discipline is supported by the evidence-based biomedical research. Scientific discoveries or improvements are made by experiments and clinical trials with different research designs, and are analyzed by complex methods of statistical assessment. Research conducted at university is of particular interest, as it is a place with a wide selection of laboratorial and/or clinical facilities and a research staff. University research aims not only to accumulate new data but also to disseminate it among students by teaching. As the university community is based on the creation and extension of certain values admitted by all its members, university research brings into life new perspectives for research and founds the ways to benefit all members of both biomedical and non-biomedical society. Values as the main characteristics of modern civic society are important both from research point of view and of its perspectives. Thus, public health research may be transformed into an effective tool to rethink the assessment of old values and a formation of new ones.
Hemos derrotado al olvido: sobre la inmortalidad digital
Authors: Rojas Parma Lorena
Published: June 2021

La preocupación humana por la inmortalidad tiene una larga historia. En nuestros tiempos, con las promesas de la biotecnología y el transhumanismo, se nos anuncia una posibilidad de cumplir con ese sueño del corazón humano. Con todo, hoy, sin los complejos procesos que se implican en esas promesas, contamos con una tecnología que nos permite dar cuenta de nuestra vida en un sentido inmortal. Por toda la “eternidad digital” habrá pruebas de que vivimos: fotos, videos, búsquedas, conversaciones y un largo etcétera, nos resguardarán por siempre del abismo del olvido.  Los registros dejados en nuestras cuentas virtuales van a permanecer en la red, y una inmortalidad digital protegerá nuestro paso por la tierra. El artículo se propone explorar esta experiencia y sus posibles consecuencias.
Eingriffsbefugnisse nach der Leerverkaufs-VO bei Bedrohungen der Finanzstabilität und des Marktvertrauens

Das von der BaFin am 18. 2. 2019 erlassene Leerverkaufsverbot in Aktien der Wirecard AG ist bei der kritischen Aufarbeitung der Rolle von BaFin und BMF im Wirecard-Skandal zunehmend ins Zentrum gerückt. Insbesondere im Wirecard-Untersuchungsausschuss wird das Leerverkaufsverbot als „falsches Gütesiegel“ mitverantwortlich gemacht für die noch bis zum Tag der Stellung des Insolvenzantrags fortgeführten Tätigkeiten des einstigen deutschen Vorzeige-FinTechs. Doch nicht nur aus heutiger Sicht, sondern auch auf Basis der Tatsachen, die der BaFin am 18. 2. 2019 bekannt waren, bestehen durchgreifende Bedenken gegen die Rechtmäßigkeit des Leerverkaufsverbots. Aufbauend auf einer ausführlichen Ausarbeitung der Tatbestandsvoraussetzungen für den Erlass einer Notfallmaßnahme gem. Art. 20 Abs. 2 Leerverkaufs-VO macht der Beitrag klar, dass die tatbestandlichen Voraussetzungen für das Wirecard-Leerverkaufsverbot nicht gegeben waren.
Effect of calcite addition on technical properties and reduction of formaldehyde emissions of medium density fiberboard
Authors: Camlibel Osman
Published: June 2021

Physical, mechanical, and formaldehyde emission properties were studied for medium density fiberboard (MDF) produced with oak (75%) and pine (25%) fibers that had been mechanically refined in the presence of calcite particles. The calcite slurry was prepared at two levels of solids, 1.5% and 3% (10 and 20 kg·m-³). Chips were cooked for 4 min at 185 °C, under 8 bar vapor pressure in an Andritz defibrillator. 1.8% liquid paraffin, 0.72% ammonium sulphate solution, and 11% urea-formaldehyde were added by percentage based on oven-dried wood fibers in the blowline at the exit of the defibrator. The fibers were dried to 11% moisture content. MDF boards (2100 mm × 2800 mm × 18 mm) were created using a continuous hot-press process. The addition of calcite in the course of MDF production resulted in improved physical properties, such as thickness swelling (ThS 24 hours) and water absorption (WA 24 hours). MDF boards prepared with calcite exhibited higher internal bond (IB), modulus of rupture (MOR), and modulus of elasticity (MOE). Resistance to axial withdrawal of screw also was increased by addition of 3% calcite. In addition, the lowest levels of formaldehyde emission were observed for MDF prepared with calcite at the 3% level.

Lignocellulolytic white-rot fungi allow the bioconversion of agricultural wastes into value-added products that are used in a myriad of applications. The aim of this work was to use corn residues (Zea mays L.) to produce valuable products under solid-state fermentation (SSF) with Pleurotus ostreatus. White-rot fungus P. ostreatus was isolated from maize silage (MS) and thereafter it was inoculated on MS as substrate and compared with maize stover (MSt) and maize cobs (MC) to determine the best lignocellulosic substrate for the production of lignocellulolytic enzymes and extracellular protein. The MS gave the highest productivity of CMCase (368.2 U/mL), FPase (170.5 U/mL), laccase (11.4 U/mL), and MnPase (6.6 U/mL). This is compared to productivity on MSt of 222 U/mL, 50.2 U/mL, 4.55 U/mL, and 2.57 U/mL, respectively; and productivity on MC at the same incubation period as 150.5 U/mL, 48.2 U/mL, 3.58 U/mL, and 2.5 U/mL, respectively. The levels of enzyme production declined with increasing incubation period after 15 and 20 days using MS and MC, respectively, as substrates. Maximum liberated extracellular protein content (754 to 878 µg/mL) was recorded using MS, while a low amount (343 to 408 µg/mL) was liberated with using MSt and MC.

Designing RESTful API for the e-procurement system in private sector
Authors:   Institute of Software Systems NAS of Ukraine, Doroshenko А.Yu. , Bodak B.V. ,   NTUU "KPI"
Published: June 2021

The software for the e-procurement system was developed based on .NET Core RESTful API with Open API specifications. The server side uses RESTful API which ensures compatibility with the ma-jority of clients and enables them to exchange information in JSON format. The authentication and authorization flow was implemented using OAuth open standard paired with Microsoft Identity Service. User roles and functionality were handled with a standalone service for authentication and registration that made our system efficient and scalable. Business logic was designed to be split into micro-services accessible through rout-ing controllers. This approach allowed us to separate the responsibilities between the server and the client side. Special authorization headers passed during modi-fication queries allowed us to control and restrict access to particular resources for unauthorized users. The distributed cache mechanism inside the data repository level was used in order to increase the responsiveness of the system. The state handling subsystem was designed utilizing Finite State Machine concepts. The developed system was verified using unit and integration tests.
Comparison of the effectiveness of the Map-Reduce approach and the actor model in solving problems with high connectivity of inp data on the example of the optimization problem for a swarm of particles

The paper defines the notion of distributed problems with bounded input components. Particle Swarm Optimization problem is shown to be an example of such a class. Such a problem's implementation based on the Map-Reduce model (implemented on the Spark framework) and an implementation based on an actor model with shared memory support (implemented on Strumok DSL) is provided. Both versions' performance assessment is conducted. The hybrid actor model is shown to be an order of magnitude more effective in time and memory efficiency than Map-Reduce implementation. Additional optimization for the hybrid actor model solution is proposed. The prospects of using the hybrid actor model for other similar problems are given
