Las nociones de “archivo”, “posverdad” y “capitalismo gore” se vuelven un elemento imprescindible para el análisis de la pieza y la comprensión del acto de desaparición.
La articulación de la oposición siria a la luz del Proceso de Ginebra (2011-2016). Origen y limitaciones de su actividad
Authors: Bazaga Ceballos Lucía
Published: December 2021

Este artículo reconstruye la composición y las alianzas de los tres grupos opositores sirios que, bajo el amparo de la comunidad internacional, se dieron entre 2011 y 2016: el CNS, la CNFROS y el ACN. El objetivo es valorar cómo la injerencia de las potencias extranjeras en el desarrollo de la oposición al régimen de Bashar al-Assad ha influido en el propio devenir del Proceso de Ginebra, la vía planteada por Naciones Unidas para otorgar una solución política al conflicto. Para evitar la reproducción de una visión reduccionista, el método seguido se ha basado en la puesta en relación de los planos doméstico, regional e internacional que han intercedido en el conflicto. De este modo, se ha vislumbrado cómo la oposición arrastró consigo dos problemas fundamentalmente: carecía de legitimidad dentro de Siria y tenía una dependencia total de sus patrocinadores. En consecuencia, la injerencia extranjera pareció determinar la asimetría del conflicto y la forma en que las partes enfrentadas se relacionaron, de tal forma que el Proceso de Ginebra se planteó como un juego de suma cero de difícil solución que acabó por ceder el papel de árbitro del conflicto al máximo valedor del régimen, Rusia.

Published: December 2021

This research suggests a maxmin model for the selection of investment portfolios. The risk evaluation coefficients are introduced. The components of portfolio are found by solving linear programming task in onemodel and non-linear programming task in the other.  In the experimental part of the research ineffective portfolios exerted from these models are tested referring to the statistical data of the Baltic stock market. Realizations of the suggested portfolios with different risk coefficient values are compared to realizations of effective (Pareto optimal) portfolios.
Comparison of estimation methods for the density of autoregressive parameter in aggregated AR(1) processes
Authors: Celov Dmitrij , Leipus Remigijus , Kvedaras Virmantas
Published: December 2021

The article investigates the properties of two alternative disaggregation methods. First one, proposed in Chong (2006), is based on the assumption of polynomial autoregressive parameter density. Second one, proposed in Leipus et al. (2006), uses the approximation of the density by the means of Gegenbauer polynomials. Examining results of Monte-Carlo simulations it is shown that none of the methods was found to outperform another. Chong’s method is narrowed by the class of polynomial densities, and the secondmethod is not effective in the presence of common innovations.Bothmethodswork correctly under assumptions proposed in the corresponding articles.

Вплив оздоровчо-рухової активності на вегетативний баланс жінок похилого віку
Authors: Рубан Лариса , Путятіна Галина , Цигановська Наталія
Published: December 2021

Мета: на підставі аналізу сучасної спеціальної літератури вивчити вегетативний баланс в осіб похилого віку за допомогою проведення кардіоінтервалографії в динаміці оздоровчо-рухової активності.

Матеріал і методи: до дослідження було залучено 60 жінок похилого віку. Жінки Гр.1 (n=24) відносно здорові; жінки Гр. 2 (n=17) з періодично виникаючим підвищенням артеріального тиску до 150/90 мм.рт.ст.; жінки Гр. 3 (n=19) з постійними показниками артеріального тиску 150/90 – 160/100 мм.рт.ст., проте, медикаментозну терапію не приймали. Запис кардіоінтервалографії було зроблено за допомогою комп’ютерної системи CardiolabPlus.

Результати: жінки Гр.1 мали збалансований вплив симпатичного і парасимпатичного відділів вегетативної нервової системи. В Гр.2 на тлі нормального вихідного вегетативного тонусу при ортостатичній пробі спостерігали гіперсимпатикотонічну реактивність. У жінок Гр.3 встановлено розвиток в організмі напруги регуляторних вегетативних і гуморальних систем. Розроблено оздоровчу програму, яка була представлена освітньою частиною, ранковою гігієнічною гімнастикою та оздоровчою ходьбою. Динаміка змін у жінок Гр. 2 вказала на поліпшення вегетостабілізуючих властивостей, зниження напруженості механізмів вегетативної регуляції ВНС, завдяки впливу оздоровчо-рухової активності. У жінок Гр.3 спостерігали позитивну тенденцію. Проте, початковий вегетативний тонус коливався в межах ейтонії з вираженою гіперсимпатикотонічною реактивністю. Високий показник індексу напруги після ортостатичної проби вказує на наявність в організмі жінок Гр.3 напруги регуляторних вегетативних і гуморальних систем, що є наслідком неконтрольованого підвищення артеріального тиску.

Висновки: результати проведеного дослідження вказують на наявність у жінок похилого віку вегетативного дисбалансу з переважанням активності симпатичного відділу вегетативної нервової системи і перенапругою регуляторних систем. Розробка програм оздоровчо-рухової активності буде сприяти покращенню стану здоров’я, продовженню активного та повноцінного життя осіб похилого та літнього віку.

Ключові слова: похилий вік, кардіоінтервалографії, варіабельність серцевого ритму.

Authors:   Association of Employers’ Organizations of Ukraine, Kostrytsya Vasil , Burlai Tetiana ,   State Institution "Institute for Economics and Forecasting, NAS of Ukraine"
Published: December 2021

The shocking consequences of the COVID-19 pandemic have exacerbated the need to ensure the resilience of societies in the face of new epidemiological challenges. An integral element of the resilience system is the efficiency, balance and sustainability of national labor markets and the employment sector as a whole, which has had a devastating effect on the “coronavirus”. The purpose of the study is to identify global post-pandemic destructions in the field of employment, determine the main ways and factors of its recovery, as well as the resource potential of international management structures necessary to accelerate this process. Used statistical and analytical approaches, as well as methods of systemic, comparative and graphical analysis. Analyzed modern international approaches to the formation of employment recovery policy aimed at overcoming the negative consequences of the COVID-19 pandemic for the world of work, public welfare and social justice. The resource potential of new UN and ILO initiatives to stabilize employment and accelerate the pace of its recovery on a global scale has been revealed. The key factors of the global dynamics of employment recovery have been identified, including: anti-malignant vaccination; fiscal stimulus; labor productivity; work migration; the level of development of national social protection systems and labor market institutions, digitalization, as well as involvement of countries in integration processes. The results of the study prove that in the formation of modern state policy aimed at accelerating the post-pandemic recovery of the economy and society, the key factors of employment recovery, as well as the corresponding strategic initiatives of international institutions, should be taken into account.

This paper analyses the state of power engineering in Ukraine and the main trends in the development of the world market in the field of converting high-capacity powerful power units of thermal power plants into ultra-supercritical (USC) ones. It is shown that the energy sector of Ukraine requires special attention and the introduction of new modern technical solutions. Worldwide trends indicate that the emphasis is now on increasing the steam parameters before a turbine to ultra-supercritical ones. This allows one both to increase the efficiency of power units and to reduce thermal emissions, fighting the global environmental problem of climate warming. The implementation of this approach is proposed taking into account the realities of the Ukrainian economy and the available technical capabilities of the power engineering industry. This paper presents the results of variational computational studies of the thermal scheme of the 300 MW power unit of the K-300-23.5 turbine to be converted into a USC one. The problem was solved under the condition of maximizing the preservation of the thermal scheme, increasing the efficiency of the power unit and minimizing capital investments during the modernization of the turbine. It was chosen to preserve the regeneration system, as well as the medium-pressure (MP) and low-pressure (LP) cylinders. Considered and calculated were variants with the addition to the existing turbine of a USC cylinder and the creation of a new high-pressure cylinder (HPC) with insignificant changes in its overall characteristics. The results of computational studies showed that the most rational variant for modernizing the 300 MW turbine plant is the creation of a new HPC designed for operation at USC steam parameters as well as the addition to the IPC of a new cylinder with the purpose of increasing the reheat steam parameters while preserving the regeneration system.
Vibrations of a Cylindrical Sandwich Shell with a Honeycomb Core Made Using FDM technology

Presented is a model of the dynamic deformation of a three-layer cylindrical shell with a honeycomb core, manufactured by fused deposition modeling (FDM), and skins reinforced with oriented carbon nano-tubes (CNT). A ULTEM 9085 thermoplastic-based honeycomb core is considered. To analyze the stress-strain state of the honeycomb core, a finite element homogenization procedure was used. As a result of this procedure, the dynamic response of the honeycomb core is modeled by a homogeneous orthotropic material, whose mechanical properties correspond to those of the core. The proposed model is based on the high-order theory, extended for the analysis of sandwich structures. The skin displacement projections are expanded along the transverse coordinate up to quadratic terms. The honeycomb core displacement projections are expanded along the transverse coordinate up to cubic terms. To ensure the integrity of the structure, shell displacement continuity conditions at the junction of the layers are used. The investigation of linear vibrations of the shell is carried out using the Rayleigh-Ritz method. For its application, the potential and kinetic energies of the structure are derived. Considered are the natural frequencies and modes of vibrations of a one-side clamped cylindrical sandwich shell. The dependence of the forms and frequencies of vibrations on the honeycomb core thickness and the direction of reinforcement of the shell skins have been investigated. It was found that the eigenforms of a sandwich shell are characterized by a smaller number of waves in the circumferential direction, as well as a much earlier appearance of axisymmetric forms. This means that when analyzing the resonant vibrations of a sandwich shell, it is necessary to take into account axisymmetric shapes. Changing the direction of reinforcement of the skins with CNTs makes it possible to significantly influence the frequencies of the natural vibrations of the shell, which are characterized by a nonzero number of waves in the circumferential direction. It was found that this parameter does not affect the frequencies of the axisymmetric shapes of the shell under consideration.

An approach to the experimental and computational study of the shear properties of honeycomb cores (HC) produced using Fused Deposition Modeling (FDM) technology is proposed. The experimental approach is based on a new sample type for testing HCs for shear. This sample contains two HCs and three steel plates. Shear tests are carried out in the TiraTest 2300 universal tensile testing machine. The HCs are made of ULTEM 9085 and PLA with FDM technology, which is implemented in the 3D Fortus 900 system. The tests resulted in obtaining the shear properties of the HCs by averaging the stress-strain curves of five samples. As follows from the analysis of the experimental results, brittle destruction of an HC is observed. Before its destruction, the value of shear deformation for samples made of PLA was 0.0134, and for samples made of ULTEM, 0.0257. The experimental analysis was accompanied by numerical finite element (FE) modeling of shear experiments, taking into account the deformation of the equipment. With the FE modeling of the experiments, to describe the behavior of the samples, it is necessary to take into account the influence, on the measurements of the shear properties, of the equipment and the deformation of each honeycomb cell. The deformation of three plates was taken into account; the elastic properties of the adhesive joint were not taken into account. A computer model of the deformation of the HCs with equipment was built using ANSYS Design Modeler. With FE modeling, only the elastic behavior of the HCs was considered.

Published: December 2021

The study examined language choice of Bidayuh in mixed marriages with Melanau, Chinese, and Malay. A survey was conducted involving 101 respondents in mixed marriages in Kuching, Sarawak (18 Bidayuh-Melanau; 41 Bidayuh-Chinese; 42 Bidayuh-Malay). The objective ethnolinguistic vitality of the groups was assessed using structural factors in the community according to Giles, Taylor and Bourhis (1977): demographic strength, institutional support, and status variables. The results are as follows: Melanau, low; Bidayuh, medium to low; Chinese, medium; and Malay, high. The respondents' proficiency in their ethnic language showed that in Bidayuh-Melanau mixed marriages, proficiency in Bidayuh was retained but Melanau was lost because of its low vitality. Bidayuh-Chinese respondents' proficiency in both ethnic languages was adequate for casual conversations, indicating that languages of similar vitality levels have equal dominance in mixed marriages. In Bidayuh-Malay mixed marriages, only about one-quarter of the respondents could speak Bidayuh as their ethnic language whereas more than half were proficient in Sarawak Malay dialect because of the high vitality of the Malay. The domains where the ethnic languages are still frequently used were family, religion, and friendship but the Chinese and Malay could use their ethnic languages in the employment domain. The findings suggest that there is lack of agency of parents to pass on their ethnic language, thereby allowing the societal trend of prestigious languages to dominate.

La enmienda conjetural en la novela corta del Barroco (con una coda lazarillesca)
Authors: Tanganelli Paolo
Published: December 2021

Con ejemplos de cinco autores barrocos de novelas cortas (Camerino, Castillo Solórzano, Piña, Sanz del Castillo y Vital Pizarro y Cuña) se examinan las condiciones que, frente a errores no subsanables ope codicum, permiten acudir a la enmienda ope ingenii. Las circunstancias básicas tienen que ver, naturalmente, tanto con la reconstrucción de la probable génesis de la corruptela como con el respeto de la lengua de la época y los hábitos estilísticos del propio género. Pero, además, es necesario acatar un tercer requisito: las conjeturas deben acoplarse al usus scribendi de los respectivos autores –siempre que sea objetivable– o, a zaga del método de Poliziano, con el de sus auctoritates. En la última parte, dedicada al Lazarillo, se vuelve sobre la conjetura “deste artife” (Ruffinatto), proponiendo una explicación alternativa de la probable deturpación “deste arte”.
La novela corta en los catálogos del librero Alonso y Padilla
Authors: Castillo-Martínez Cristina
Published: December 2021

Este artículo sondea la presencia de la novela corta del siglo XVII en los catálogos que Pedro Joseph Alonso y Padilla fue distribuyendo en su librería. Se han tenido en cuenta las distintas versiones de lo que hizo desde 1720 a 1740, analizando después aquellos títulos que realmente editó. Por qué eligió unos y no otros se antoja difícil de averiguar, pero sí que es revelador el hecho de que se fijara en nombres tan representativos como Cervantes, Zayas, Carvajal, Castillo Solórzano o Salas Barbadillo.
«La gitanilla» (Anónimo, 1914) y «La ilustre fregona» (Francisco Carrillo Casado, 1926): dos guiones cervantinos del cine mudo

El presente artículo rescata un par de guiones del cine primitivo: La gitanilla (Anónimo, 1914) –conservado en la Bibliothèque Nationale de France– y La ilustre fregona (Francisco Carrillo Casado, 1926) –Biblioteca Nacional de España–, basados en sendos relatos de Cervantes (Novelas ejemplares, 1613). Primero, pasaré revista a las adaptaciones perdidas de la colección barroca; sondearé después el concepto de “guion” en la era muda; y, por último, profundizaré en ambas reescrituras, atendiendo tanto a su peculiaridad formal como a sus divergencias argumentales respecto a los textos base.
O potrzebie badań lokalnych pogranicza na przykładzie Babimojszczyzny w XX wieku
Authors:   Mgr, Uniwersytet Zielonogórski, Wydział Humanistyczny, Polska, Zielińska Katarzyna
Published: December 2021

The aim of the study is an attempt to refer to the historiography of a small microregion at the border of today's provinces: Lubuskie and Wielkopolskie, called "Babimojszczyzna". The time perspective relating to the events of World War I, Polish-German disputes, as well as the transformations in Poland and Germany after 1989 requires a new approach to historical narratives. The thesis of the article is the assumption that the hitherto historiography of this complex microregion in Polish-German relations in the first half of the 20th century did not develop new approaches. Another problem is the lack of real effects under the research models on the Polish and German narratives of the last thirty years. Their lack is particularly noticed in the context of the condition of social memory in the vicinity of Babimost, where only the tradition of the Polish Uprising 1918-1919 and the struggle for Polishness is cultivated, without a broader context. The discussed region can also be an interesting example for other similar historical areas, which, like all borderlands, were the subject of natural osmosis rather than their contact.
Wpływ Euromajdanu i Rewolucji Godności na tworzenie nowych mediów na Ukrainie

Published: December 2021

The process of changing the media landscape in Ukraine cannot be called simple. At the same time, these changes are very large and irreversible - as well as changes in Ukrainian society. This paper deals with the issues related to the present media landscape of Ukraine and the factors that influence it. The work describes the relationship between the media and the events of Euromaidan and the Revolution of Dignity, as well as the identity crisis that led to the events of 2013–2014 in Ukraine. The role of the mass media in the democratic revolutions in Ukraine is very important. The changing position of the media, the influence of the oligarchs, and the resistance of media workers - all of this was a part of the revolution that changed not only Ukrainian society but also the mass media for the better. Journalists, being public figures, were active participants in the revolution and stood close to its roots. Admittedly, this had an impact on the specifics of the work of journalists who had to operate in extreme conditions, first during the Revolution of Dignity, and later broadcasting events in Crimea and eastern Ukraine. The events of the Euromaidan completely changed the situation, putting an end to the crisis of national self-identification. The media not only reflected on but also created these changes while experiencing restructuration. A new type of media has emerged – are ordinary people who, using their profiles in social networks, acted to spread the information about events, commented on them, and shared their reflections.
Organisation of Lublin confinement institutions in 1939–1944 within the ramifications of the German security apparatus
Authors:   Master of Arts, PHD student at the Maria-Curie Skłodowska University in Lublin, Poland, Michniowski Marcin ,   Museum assistant at the National Museum in Lublin, Poland
Published: December 2021

The aim of the article is to present the confinement institutions set up in Lublin in 1939–1944 by the German occupier, and to analyse the organisational aspects of their functioning in the operational context of various agencies of the security system of the Third Reich and the General Government. The first part of the essay consists of background information necessary to conduct the analysis – exposition of the administrational division of Polish territory after the September campaign and the structure of the security apparatus introduced by the German occupier. In the main body, three main stages of establishment of the confinement institutions are outlined, based on the comparison of the circumstances influencing their formation. Simultaneously, their official subordination to appropriate agencies of the security system is shown, what is compared to the actual dominance of various parties over different prisons and camps. As such, it is possible to present the whole segment of the German occupational system, from two distinctive perspectives: existence of a series of suitable institutions serving specific roles in order to strengthen the occupier’s control over the Polish population, and the competition of respective agencies of the German security apparatus over the masses of prisoners.
The Ceramics Production of the Cis-Ural Srubnaya Culture: A Case Study of the Kurgan Cemetery I Near Tverdilovo Village
Authors: Fayzullin Ildar , Kuptsova Lydiya , Mukhametdinov Vadim
Published: December 2021

The article analyzes the ceramics of the Timber culture, recovered from a kurgan cemetery near the village of Tverdilovo (excavated in 2017 in the Western Orenburg region). Under embankment of kurgan 1, 30 vessels were found in 21 burials, made in a narrow chronological interval. When considering these vessels according to one methodological system, which includes morphological and technical and technological analysis, the peculiarities of the production of pottery were highlighted both for a single group of the population and for the region as a whole. The analysis of the technological traditions of ceramics production from the Tverditovo kurgan cemetery shows that the population that left these ceramics was not homogeneous. There are two different traditions even at the stage of selection of plastic soft raw materials: one of them used silty clay for making dishes, the other applied natural clay. So, it is difficult to explain an isolated case of using sludge and low-grade ferrum clay. Using comparative analysis we can assume that the nearest burial monument according to its ceramics products is the Bogolubovskiy kurgan cemetery where we also can find silty and natural clay and the receipt of molding mass as “clay+ chamotte+ organic materials”. Pottery traditions of the population that left the presented vessels were heterogeneous, which is recorded both in terms of morphological and technological characteristics. A similar picture is typical for other settlement and burial sites in the Orenburg Cis-Urals.

Our research aims to assess the chestnut tree health status in three various locations: Baia Mare, Tauti Magheraus, Baia Sprie, in order to find the most efficient methods to prevent and to combat the bark cancer which develops in the clime conditions of Baia Mare basin. The primary assessment was performed through the determination of the attack degree (AD %), of its frequency (F%) and its intensity (I%) . We took in observation 10 chestnut trees from each location. We determined the number and size of both trunk and branches lesions for each chestnut tree. The intensity of the attack in the three studied areas ranked from the highest intensity 47.5% for Baia Sprie location followed by the intensity of 33.0 % for Tautii Magheraus, to the intensity of 26.5% for Baia Mare. Our analysis performed after the administration of the combat chemical method, we found that this measure was not efficient because the infection did not diminish; thus we recommend the dry chestnut tree elimination, its hygiene cuts, using the biologic combat.

Plant species characteristic of arid and semi-arid zones, such as Argania spinosa (L.) Skeels, have a taproot that allows them to reach the soil horizons more quickly. Unfortunately, in the nursery, the containers of culture used for the production of seedlings do not support an excellent development of the root architecture that can be able to resist the shock of transplantation, in particular of the hydric stress. This study aimed to evaluate the physiological and biochemical behavior of Argania spinosa seedlings grown in containers of different depths under water stress. An experiment was conducted with 90 seedlings from the different containers (P1 for depth of 16 cm, P2 for depth of 30 cm, and P3 for depth of 60 cm), and three watering treatments (well-watered 100% of field capacity, moderate stress with 50% of field capacity and severe stress with 25% of the field capacity). Our results showed that seedlings from the 16 cm container had lower values of water status. Malondialdehyde content, electrolyte leakage, hydrogen peroxide, and superoxide radical content gave higher values on seedlings from the shallow container. The benefits of increasing the container depth of nursery seedlings contribute to the improvement of physiological and biochemical responses of seedlings under water stress. To fully validate our findings, a long-term field study must be conducted.

This study aimed to determine the concentrations of ten metals (Mn, Ni, Ca, Mg, Fe, Zn, Cr, Pb, Cd, Cu) in the soil at depths of 10 and 20 cm and selected plant species (Populus nigra L., Fraxinus ornus L., Salix alba L., Salix caprea L.), as well as to assess the ability of these plants of metal bioaccumulation, translocation and phytoremediation on the location of the mine pit and flotation tailings of the selected mine (in the center of the Republic of Serbia). The concentrations of Pb and Cu in the investigated soil at a depth of 10 cm were above remediation values stated in the regulations of the Republic of Serbia. At the same time, the concentration of Cd, Cr, Pb and Cu was above the limit values in both of the examined soil depths, while Ni in the soil at a depth of 10 cm was above the limit value determined in the Directives of the European Union. The species F. ornus shows the ability to phytoextract Ca, species P. nigra Zn, Ca and Cd, while both Salix species have the capacity to phytoextract Zn and Ca. The results showed that species S. alba is an efficient bioaccumulator of Mn, Fe, Cr, Pb, Zn and Ca, S. caprea of Fe, Cu, Cr, Mg and Pb, and P. nigra of Mn and Cd. The bioaccumulation and translocation of the investigated elements depend on plant species and their organ. The selection of plant species adequate for remediation should take this into account.

Published: December 2021

The incidence of grapevine virus infections in Korean vineyards was investigated from July to October, 2020. A total of 177 petiole samples were collected from two or three different cultivars in each of four different regions; these were examined by reverse transcription-polymerase chain reaction assay for the presence of 14 major viruses. The overall occurrence of grapevine viruses was 91.0%, and the level of incidence was high irrespective of region or cultivar. The predominant viruses were grapevine leafroll-associated virus 3 (80.2%), grapevine fleck virus (70.6%), and grapevine rupestris stem pitting-associated virus (49.2%). Most grapevines were infected with multiple viruses, suggesting that Korean vineyards are likely to suffer economic losses resulting from viral diseases. This is the first extensive survey performed in Korea to observe the outbreak status of diverse grapevine viruses; surveys of this type can provide important information for the management of grapevine viruses in Korea.

Through the last century, the increased greenhouse gases emissions altered the atmosphere’s composition and resulted to the phenomenon known as climate change. Climate change threatens the sustainability of the agricultural sector in the Mediterranean region. Droughts and extreme heat waves will probably become more frequent in the next few decades, thus maintaining sufficient yields in heat and drought susceptible major crops will be challenging. In Greece, cotton is of paramount economic importance. Besides the fact that it is regarded as the most significant fiber crop, Greece is the main cotton producer of the European Union. The aim of the present review was to examine the environmental factors that might affect cotton production in Greece and assess whether (or not) climate change has the potential to limit the productivity of this crop in the near future. According to the existing literature, cotton can adapt to the changing climate. Climate change-induced elevated CO2 levels and temperatures might even benefit cotton. The mitigation of the adverse effects of climate change is possible via the adaptation of site-specific agronomic practices. A simplistic framework, based on the literature and the goals of the European Union, that aims to the preservation of sufficient cotton yields in Greece is proposed in the present study.

Sixteen rice genotypes were planted under normal and high temperature during 2018 and 2019 seasons to understand the mechanisms that make plants tolerant or susceptible to heat stress and methods which may lead to generate new varieties with sustainable yield production. The combined analysis showed significant differences at the level of probability 0.05 and 0.01 among years for all characters except, chlorophyll content and leaf rolling which would indicate wide differences among the weather of both years. Environment’s variance was significant at the level of probability 0.01 over all characteristics. The significant differences at the level of probability 0.01 were recorded among genotypes and G x E interaction variances for all characteristics. The highest values of panicles number plant-1 were obtained from ‘Giza 178’ and ‘Hybrid 2’, however, the highest values of 100-grain weight were recorded with ‘Giza 179’ and ‘Egyptian Yasmine’. The minimum values of sterility% were recorded with ‘Sakha 107’ and ‘IET1444’. Concerning the cultivars performance across two environments, the cultivars ‘Giza 178’, ‘Giza 179’, ‘Sakha 107’ and ‘IET 1444’ gave the best desirable values over natural and heat stress so, those cultivars are considered to play a vital role in breeding program to enhance heat stresses tolerance accompanied with high yield potential.
The occurrence of Fusarium species in white spears of Asparagus officinalis
Authors: ANDRZEJAK Roman , JANOWSKA Beata
Published: December 2021

The aim of the study was to determine the species composition of fungi of the Fusarium genus found on white Asparagus officinalis spears, depending on the presence or absence of disease symptoms, age of the plantation, date of harvest and the place from which samples were collected for mycological analysis. Additionally, the pathogenicity of selected Fusarium spp. isolates was determined. A. officinalis L. was cultivated for white spears. The research was conducted on the German dioecious cultivar ‘Eposs’. Samples of A. officinalis spears for tests were collected from two plantations. Six species of fungi of the Fusarium genus were identified in the asparagus spears: F. culmorum, F. equiseti, F. oxysporum, F. proliferatum, F. solani, and F. fujikuroi. Among the Fusarium species colonizing Asparagus officinalis the greatest threat is F. oxysporum. Always there are more isolates in the spears with the symptoms, in epidermis. The late harvest date favors the development of fusariosis. This means that the spears harvested at the latest date (late June) are the most heavily colonised by fungi. The isolates of fungi of the Fusarium genus collected from the spears exhibit pathogenicity against A. officinalis plants.

Este artículo caracteriza las prácticas comunicacionales de los comités que promovieron las consultas populares convocadas contra proyectos de extracción minero-energética en dos municipios de Colombia: Arbeláez (Cundinamarca) y Fusagasugá (Cundinamarca). Con este fin, se abordan los factores que originaron el conflicto socioambiental, se reconstruye el proceso de convocatoria a la consulta y se detalla el “repertorio de prácticas comunicacionales” que organizaron los comités promotores, comprendido como la integración de nanomedios y artes populares y su articulación con las acciones de organizaciones sociales que impulsaron las consultas. Se concluye que el proceso de comunicación de los comités robustece el reconocimiento de los conflictos socioambientales en la comunidad, expande y diversifica la opinión pública y contribuye al desarrollo de mecanismos de participación popular.

Authors:   Universidad de Buenos Aires, LENARDUZZI Victor , SAMELA Gabriela ,   Universidad de Buenos Aires Argentina
Published: December 2021

Este trabajo propone un acercamiento al problema del efecto enjambre en la comunicación contemporánea a partir de la obra de Franco Berardi, en diálogo con otros autores. Para ello se presentan sus aportes respecto de la comunicación, el semiocapitalismo y la gobernanza. Luego, se discute la idea de una “inteligencia colectiva” como potencial de creatividad y libertad a partir de la noción de generall intelect (Marx, Virno, Berardi). A partir de esta cuestión, abordamos el tema “enjambre” como la deriva de la cultura digital contemporánea y sus articulaciones con los conceptos de red y multitud.
Comunicación política en la era postcovid

En este número se presentan trabajos importantes guiados en la temática: “El subsuelo de lo político: Sustratos sociales, culturales, comunicacionales y tecnológicos de la acción colectiva en América Latina en el siglo XXI”, que en palabras de sus coordinadores expone a la economía, la cultura, la comunicación, la religión, en general lo social y, sobre todo, la política (entendida como un conjunto de prácticas, formas de pensar e instituciones que regulan y organizan la convivencia humana) han experimentado una variedad de cambios, transiciones y transformaciones que se han acelerado durante las dos primeras décadas del siglo XXI. Lo político, el conflicto, el antagonismo y el desacuerdo, según los supuestos del pensamiento filosófico posfundacional, se han destacado por ser elementos aceleradores. Mejor aún, lo político es comprendido desde esta perspectiva como un momento instituyente de dichas transformaciones. Su principal característica es el ser inasible y contingente. Lo político se manifiesta como una dimensión ontológica de la política.
