Abstract. Aerosols influence the Earth’s energy balance through direct radiative effects and indirectly by altering the cloud micro-physics. Anthropogenic aerosol emissions dropped considerably when the global COVID–19 pandemic resulted in severe restraints on mobility, production, and public life in spring 2020. Here we assess the effects of these reduced emissions on direct and indirect aerosol radiative forcing over Europe, excluding contributions from contrails. We simulate the atmospheric com- position with the ECHAM5/MESSy Atmospheric Chemistry (EMAC) model in a baseline (business as usual) and a reduced emission scenario. The model results are compared to aircraft observations from the BLUESKY aircraft campaign performed in May/June 2020 over Europe. The model agrees well with most of the observations, except for sulfur dioxide, particulate sulfate and nitrate in the upper troposphere, likely due to a somewhat biased representation of stratospheric aerosol chemistry and missing information about volcanic eruptions which could have influenced the campaign. The comparison with a business as usual scenario shows that the largest relative differences for tracers and aerosols are found in the upper troposphere, around the aircraft cruise altitude, due to the reduced aircraft emissions, while the largest absolute changes are present at the surface. We also find an increase in shortwave radiation of 0.327 ± 0.105 Wm−2 at the surface in Europe for May 2020, solely attributable to the direct aerosol effect, which is dominated by decreased aerosol scattering of sunlight, followed by reduced aerosol absorption, caused by lower concentrations of inorganic and black carbon aerosols in the troposphere. A further in- crease in shortwave radiation from aerosol indirect effects was found to be much smaller than its variability. Impacts on ice crystal- and cloud droplet number concentrations and effective crystal radii are found to be negligible.

Abstract. We collected surface snow samples from three different glaciers: Yala, Thana, and Sachin in the central and western Himalayas to understand the spatial variability and radiative impacts of light-absorbing particles. The Yala and Thana glaciers in Nepal and Bhutan, respectively, were selected to represent the central Himalayas. The Sachin glacier in Pakistan was selected to represent the western Himalayas. The samples were collected during the pre-and post-monsoon seasons of the year 2016. The samples were analysed for black carbon (BC) and water-insoluble organic carbon (OC) through the thermal optical method. The average mass concentrations (BC 2381.39 ng g−1; OC 3896.00 ng g−1; dust 101.05 µg g−1) in the western Himalaya (Sachin glacier) were quite higher compared to the mass concentrations (BC 357.93 ng g−1, OC 903.86 ng g−1, dust 21.95 µg g−1) at the central Himalaya (Yala glacier). The difference in mass concentration may be due to the difference in elevation, snow age, local pollution sources, and difference in meteorological conditions. BC in surface snow was also estimated through WRF-Chem simulations at the three glacier sites during the sampling periods. Simulations reasonably capture the spatial and seasonal patterns of the observed BC in snow but with a relatively smaller magnitude. Absolute snow albedo was estimated through the Snow, Ice, and Aerosol Radiation (SNICAR) model. The absolute snow albedo reduction was ranging between 0.48 % (Thana glacier during September) to 24 % (Sachin glacier during May) due to BC and 0.13 % (Yala glacier during September) to 5 % (Sachin glacier during May) due to dust. The instantaneous radiative forcing due to BC and dust was estimated in the range of 0 to 96.48 W m−2 and 0 to 25 W m−2 respectively. The lowest and highest albedo reduction and radiative forcing were observed in central and western Himalayan glaciers, respectively. The potential source regions of the deposited pollutants were inferred using WRF-Chem tagged-tracer simulations. Selected glaciers in the western Himalayas were mostly affected by long-range transport from the Middle East and Central Asia; however, the central Himalayan glaciers were mainly affected by local and South Asia emissions (from Nepal, India, and China) especially during the pre-monsoon season. Overall, South Asia and West Asia were the main contributing source regions of pollutants.

Published: December 2021

Abstract. The kinetics of the gas-phase reactions of hydroxyl radicals with cyclohexene oxide (CHO), 1,2-epoxyhexane (EHX), 1,2-epoxybutane (12EB), trans-2,3-epoxybutane (tEB) and cis-2,3-epoxybutane (cEB) have been investigated using the relative rate technique. The experiments have been performed at (298 ± 3) K and (760 ± 10) Torr total pressure of synthetic air using different reference compounds in a 1080 l Quartz Reactor (QUAREC) and a 480 l Duran glass chamber. The following room temperature rate coefficients (cm3 molecule−1 s−1) were obtained: k1 (OH+CHO) = (5.93 ± 1.78) × 10−12, k2 (OH+EHX) = (5.77 ± 1.29) × 10−12, k3 (OH+12EB) = (1.98 ± 0.39) × 10−12, k4 (OH+cEB) = (1.50 ± 0.26) × 10−12, k5 (OH+tEB) = (1.81 ± 0.42) × 10−12. With the exception of previous studies for 1,2-epoxybutane and cyclohexene oxide, this is to the best of our knowledge the first kinetic study of the reaction of these compounds with OH radicals. Atmospheric lifetimes, reactivity trends and atmospheric implications are discussed considering the epoxy compound rate coefficients obtained in the present study. In addition to a direct comparison with the literature data where possible, the results from the present study are compared with values estimated from the Structure Activity Relationship method.
10 years of temperature and wind observation on a 45 m tower at Dome C, East Antarctic plateau

Published: December 2021

Abstract. Long-term, continuous in situ observations of the
near-surface atmospheric boundary layer are critical for many weather and
climate applications. Although there is a proliferation of surface stations
globally, especially in and around populous areas, there are notably fewer
tall meteorological towers with multiple instrumented levels. This is
particularly true in remote and extreme environments such as the East
Antarctic plateau. In the article, we present and analyze 10 years of data
from six levels of meteorological instrumentation mounted on a 42 m tower
located at Dome C, East Antarctica, near the Concordia research station,
producing a unique climatology of the near-surface atmospheric environment
(Genthon et al., 2021a, b). Monthly temperature and wind data demonstrate
the large seasonal differences in the near-surface boundary layer dynamics,
depending on the presence or absence of solar surface forcing. Strong
vertical temperature gradients (inversions) frequently develop in calm,
winter conditions, while vertical convective mixing occurs in the summer,
leading to near-uniform temperatures along the tower. Seasonal variation in
wind speed is much less notable at this location than the temperature
variation as the winds are less influenced by the solar cycle; there are no
katabatic winds as Dome C is quite flat. Harmonic analysis confirms that
most of the energy in the power spectrum is at diurnal, annual and
semi-annual timescales. Analysis of observational uncertainty and
comparison to reanalysis data from the latest
generation of ECMWF (European Centre for Medium-Range Weather Forecasts)
reanalyses (ERA5) indicate that wind speed is
particularly difficult to measure at this location. Data are distributed on the PANGAEA data repository at
https://doi.org/10.1594/PANGAEA.932512 (Genthon et al., 2021a) and

Simulation Model of Reactive Nitrogen Species in an Urban Atmosphere using a Deep Neural Network: RND v1.0
Authors: Gil Junsu , Lee Meehye , Kim Jeonghwan , Lee Gangwoong , Ahn Joonyoung
Published: December 2021

Abstract. Nitrous acid (HONO), one of the reactive nitrogen oxides (NOy), plays an important role in the formation of ozone (O3) and fine aerosols (PM2.5) in the urban atmosphere. In this study, a simulation model of Reactive Nitrogen species using Deep neural network model (RND) was constructed to calculate the HONO mixing ratios through a deep learning technique using measured variables. A Python-based Deep Neural Network (DNN) was trained, validated, and tested with HONO measurement data obtained in Seoul during the warm months from 2016 to 2019. A k-fold cross validation and test results confirmed the performance of RND v1.0 with an Index Of Agreement (IOA) of 0.79 ~ 0.89 and a Mean Absolute Error (MAE) of 0.21 ~ 0.31 ppbv. The RNDV1.0 adequately represents the main characteristics of HONO and thus, RND v1.0 is proposed as a supplementary model for calculating the HONO mixing ratio in a high- NOx environment.
Effects of point source emission heights in WRF–STILT: a step towards exploiting nocturnal observations in models
Authors: Maier Fabian , Gerbig Christoph , Levin Ingeborg , Super Ingrid , Marshall Julia , Hammer Samuel
Published: December 2021

Abstract. An appropriate representation of point source emissions in atmospheric transport models is very challenging. In the Stochastic Time Inverted Lagrangian Transport model (STILT), all point source emissions are typically released from the surface, meaning that the actual emission stack height plus subsequent plume rise is not considered. This can lead to erroneous predictions of trace gas concentrations, especially during nighttime when vertical atmospheric mixing is minimal. In this study we use two WRF–STILT model approaches to simulate fossil fuel CO2 (ffCO2) concentrations: (1) the standard “surface source influence (SSI)” approach, and (2) an alternative “volume source influence (VSI)” approach, where nearby point sources release CO2 according to their effective emission height profiles. The comparison with 14C-based measured ffCO2 data from two-week integrated afternoon and nighttime samples collected at Heidelberg, 30 m above ground level, shows that the root-mean-square deviation (RMSD) between modelled and measured ffCO2 is indeed almost twice as high during night (RMSD = 6.3 ppm) compared to the afternoon (RMSD = 3.7 ppm) when using the standard SSI approach. In contrast, the VSI approach leads to a much better performance at nighttime (RMSD = 3.4 ppm), which is similar to its performance during afternoon (RMSD = 3.7 ppm). Representing nearby point source emissions with the VSI approach could, thus, be a first step towards exploiting nocturnal observations in STILT. To further investigate the differences between these two approaches, we conducted a model experiment in which we simulated the ffCO2 contributions from 12 artificial power plants with typical annual emissions of one million tons of CO2 and with distances between 5 and 200 km from the Heidelberg observation site. We find that such a power plant must be more than 50 km away from the observation site in order for the mean modelled ffCO2 concentration difference between the SSI and VSI approach to fall below 0.1 ppm.

Abstract. Numerical models are needed for evaluating aerosol processes in the atmosphere in state-of-the-art chemical transport models, urban-scale dispersion models and climatic models. This article describes a publicly available aerosol dynamics model MAFOR (Multicomponent Aerosol FORmation model; version 2.0); we address the main structure of the model, including the types of operation and the treatments of the aerosol processes. The main advantage of MAFOR v2.0 is the consistent treatment of both the mass- and number-based concentrations of particulate matter. An evaluation of the model is also presented, against a high-resolution observational dataset in a street canyon located in the centre of Helsinki (Finland) during an afternoon traffic rush hour on 13 December 2010. The experimental data included measurements at different locations in the street canyon of ultrafine particles, black carbon, and fine particulate mass PM1. This evaluation has also included an intercomparison with the corresponding predictions of two other prominent aerosol dynamics models, AEROFOR and SALSA. All three models fairly well simulated the decrease of the measured total particle number concentrations with increasing distance from the vehicular emission source. The MAFOR model reproduced the evolution of the observed particle number size distributions more accurately than the other two models. The MAFOR model also predicted the variation of the concentration of PM1 better than the SALSA model. We also analysed the relative importance of various aerosol processes based on the predictions of the three models. As expected, atmospheric dilution dominated over other processes; dry deposition was the second most significant process. Numerical sensitivity tests with the MAFOR model revealed that the uncertainties associated with the properties of the condensing organic vapours affected only the size range of particles smaller than 10 nm in diameter. These uncertainties do not therefore affect significantly the predictions of the whole of the number size distribution and the total number concentration. The MAFOR model version 2 is well documented and versatile to use, providing a range of alternative parametrizations for various aerosol processes. The model includes an efficient numerical integration of particle number and mass concentrations, an operator-splitting of processes, and the use of a fixed sectional method. The model could be used as a module in various atmospheric and climatic models.
“¿No habría algún lugar en que se pudiese estar como en la propia casa?” Saenz, la cuestión del “estar”, el encuentro con Heidegger y la proyección de estos asuntos en Kusch y Churata
Authors: Monasterios Pérez Elizabeth
Published: December 2021

This article addresses one of the major themes for reflection in Jaime Saenz's work: the question of “el estar”, developed as an artistic-epistemological elaboration that owes nothing to Western metaphysics. What interests here is to expose a poetic, critical and philosophical tradition of Latin American making, which is built around an ontology of "estar" and through the intervention of three key thinkers who in decisive moments of their reflection coincided in Bolivia: Jaime Saenz, Gamaliel Churata and Rodolfo Kusch. From different perspectives and expectations, these thinkers installed the philosophical provocation of "estar", giving way to the disturbing proposal that "estar” in life could precede and / or problematize the Heideggerian "being" in-the-world. The present work addresses these discussions in the case of Jaime Saenz.

Existence and Negativity: The Relevance of the Patočka–Bergson Controversy over Nothingness
Authors: Čapek Jakub
Published: December 2021

In in the second half of the 1940s, Jan Patočka emphasized the essentially negative character of human existence. He thus found himself in the neighborhood of Sartre’s existentialism, Heidegger’s philosophy of being, and Hegel’s dialectic, and at the same time in opposition to schools of thought which either completely reject the substantive use of “the nothing,” such as Carnap’s positivism, or relativize it, like Bergson. It is the latter polemic, Patočka’s with Bergson, which is discussed in this article. The concept of negativity in Patočka basically refers to the idea that human existence is defined by a capacity to adopt a distance toward what is pre-given, be it the reality of the physical world or the established habits and rules of a particular society. Negativity qua distance has in Patočka an absolute character. It is this claim that he defends in his critique of Bergson. The article attempts to reconstruct Patočka’s position. I claim that the wager on absolute negativity does not make Patočka a nihilist, but a philosopher of a negative holism, and, in a sense, even a moralist. Above a reconstruction of Patočka’s stance, I spell out some reservations focused especially on the systematic meaning of Patočka’s recourse to negativity. I suggest that negation is an indispensable part of a more complex existential structure Patočka is aiming at. The terms he uses for this structure include “thirst for the absolute,” “thirst for reality,” “restlessness of the heart” and “desire.” To translate these allusions onto a general plan, it is useful to talk about the capacity to establish differences that matter. As general as it seems, this turn of phrase can grasp both Patočka’s emphasis on negativity, and his emphasis on the absolute, the latter – nevertheless – not residing in a distance from being, but in differences established, maintained and abandoned by ourselves within being.

El estudio comparado de literatura y pintura,acompañado por la propia reflexión de ambos artistas, ofrece la oportunidad de abordar desde unaperspectiva múltiple ciertas características de las subjetividades representadas por el poeta y el pintor,cuya existencia aparece ligada a un profundo sentimiento trágico. Palabra, imagen y reflexión románticaemergen en este diálogo entre Hölderlin y Friedrich para ofrecer una fecunda clave de lectura a partir delo trágico, tanto en su dimensión artística, como vivencial.
Entre imaginación y representación. A propósito de la estética del espectáculo y la potencia imaginal de la existencia
Authors: González Araneda Sergio
Published: December 2021

A partir de las reflexiones filosóficas de Guy Debord intentamos repensar el cruce entre espectáculo y metafísica de la imagen en un contexto de capitalismo anárquico secular. Para esto, tomamos como guía de análisis la génesis y constitución de una estética del espectáculo que despliega y significa el mundo como mera representación de lo real. En un segundo momento, y con el concurso de Benjamin, Agamben y Heidegger, se hará patente la latencia del capitalismo como religión, dentro de la constelación de un capitalismo omniabarcante y tecnificado. Finalmente, mostraremos la modalidad  en que la metafísica de la imagen, administrada por una técnica de operatividad determinada, deviene en un orden fundamental, representativo y estático de sentido. Desde este contexto, planteamos una posibilidad tanto teórica como práctica de desarticular el espectáculo representativo (y representante) a partir de lo que denominamos potencia imaginativa de la existencia.
El problema de la objetividad en las imágenes de la naturaleza: Von Humboldt y Goethe
Authors: Gutiérrez García Rosa
Published: December 2021

El presente estudio quiere problematizar la noción de objetividad en las imágenes de la naturaleza a través de Von Humbold y Goethe, en el debate de la representación científica y a través de la relación ciencia-arte. Para ello, el presente ensayo se ha dividido en dos partes diferenciadas. En la primera se expone un estado de la cuestión sobre los párametros manejados en torno a la idea de objetividad, tanto en el contexto científico como en el filosófico, exponiendo los antecedentes pictóricos que darán paso a la segunda parte de este ensayo, y el modo en que éstas ideas se dilucidan en los casos particulares de von Humboldt y Goethe.
Dreams, the Female Gaze, and the City of Paris: Urban Landscapes through the Writings of the Surrealist Movement
Authors: Barreiro León Bárbara
Published: December 2021

From the time of the Renaissance, treaties on architecture, odes to the arts, and the study of their canons through written sources, have served to defend, emphasise, or proclaim the validity of different artistic forms and styles. In this way, programmes and manifestos have reinforced the character of organisations and movements through their fundamental ideas. The artistic Avantgardes have thus used this literary resource to lay the theoretical foundations for their future artistic contributions, being able to justify without any qualifications their most extravagant occurrences. The Avant-garde manifesto shall therefore be considered a literary contribution written in the first place for the subsequent development of the artistic and creative activity of the group or school. The Surrealist Movement generated a lot of written work because the founders, André Breton, Louis Aragon, and Philippe Soupault, were writers. Some of these texts included the Movement’s two manifestos, periodicals such as Le Surréalisme au service de la révolution, Littérature, or Minotaure, and individual writings that were penned by Breton and Aragon. This study will relate the Surrealist written work with the Movement’s idea of the city and its urban imaginary.
Roland Barthes, lo fílmico versus el cine. El sentido suspendido como definición de la modernidad cinematográfica
Authors: Monterrubio Ibáñez Lourdes
Published: December 2021

El presente artículo pretende analizar los textos de Roland Barthes sobre la práctica cinematográfica. Su resistencia al cine, vinculada a su escritura autobiográfica, se revela como la imposibilidad de fetichizar la imagen en movimiento, que debe entonces ser reducida a lo fotográfico, definiendo así un sentido obtuso que opone lo fílmico al cine. Sin embargo, a través de la concepción del sentido suspendido, Barthes detectó el surgimiento de una modernidad cinematográfica que era capaz, precisamente, de superar ese límite; a saber, destruir la imagen-acción y su temporalidad sin detener el movimiento. La elección de obras de Buñuel, Bergman, Resnais, Pasolini y Antonioni configura una concepción del sentido suspendido vinculada a la suspensión de la temporalidad y el extrañamiento que prefiguran la imagen-tiempo deleuziana. Barthes halla en la modernidad cinematográfica el punto ciego de su capacidad analítica, la de una imagen que suspende el sentido sin detener su movimiento.
Barthes: el inicio
Authors: Villacañas Berlanga José Luis
Published: December 2021

Este trabajo ofrece un análisis de la dialéctica de los conceptos placer (plaisir) y goce (jouissance) en la trayectoria de Roland Barthes. Desgarrado entre estos dos términos que debían activarse en el texto, toda su teoría dependía de una dialéctica neutra entre ellos que mostrara la afinidad entre el placer y el mandarinato de la lectura, y que dejara el papel para una revolución inaudita a la jouissance. El estudio muestra cómo el juego entre los dos términos conduce a una posición difícil de mantener, lo que llevó a su autor a proponer en Sade, Fourier, Loyola una forma de repetir el exceso y entrar en el punto cero del significado, una repetición formal, sin contenido y sin fin, pero también placentera.
Priscillianism and Women
Authors: Burrus Virginia
Published: December 2021

Several names of women who were supporters of Priscillian are known, such as Euchrotia, Procula, Urbica, Hedibia, and Agape, but they are to us no more than shadowy figures. To proceed further than what prosopography has to offer, we must depend on ambiguous evidence: the accusation of magical practices and sexual promiscuity in the Council of Saragossa, the debated female authorship of two anonymous letters preserved in a single, possibly Gallic manuscript, and lastly the Life of Saint Helia, where the issue of virginity is prominent but whose links with Priscillianism are at best tenuous.

According to the investigations conducted in the Yerevan parks and public gardens, the growth and development of the fragrant tree species are retarded due to the life activity of Obolodiplosis robiniae (black locust gall midge), Euura tibialis (sawflies) and Halyomorpha halys (brown marmorated stink bug); they also lose their decorative appearance. Besides, favorable conditions are created for the development of other pests.
The results of trials have indicated that the mentioned strains of BT microbiological preparation are rather effective, and hence can be applied in the planned and integrated struggle against E. tibialis, O. robiniae and H. halys.

Jaloukavacharan is sort of Raktmokshana which is drilled internationally in India since antiquated occasions to treat Oshthrogas, in which vitiated Kapha, Pitta and Rakta Doshas get let from the body. Jaloukavacharan is a powerful blood filtration treatment which has property to die down the aggravation, enlarging, redness and consuming sensation promptly and in which little amount of blood eliminated to kill collected vitiated Pitta,Kapha and Rakta dosha of many blood borne sicknesses. Accordingly sicknesses brought about by Pitta, Kapha and Rakta Dosha are remembered. Likewise it is a lot more secure and less confounded Normal interaction. Jalaukavcharana is exceptionally powerful old strategy for Panchakarma ignored by Physicians. There are many results of present day medication. So it is the need to spread mindfulness about Jalaukavcharana and its adequacy. In this manner Jalaukavcharana is the elective treatment promising more powerful and more secure results for the general public.

Anketa je propitivala stavove učenika i nastavnika iz više škola o različitim
situacijama vezanima uz korištenje interneta i ostavljanje digitalnih tragova.
Među anketnim pitanjima nalazilo se i devetnaest pitanja vezanih uz etičko

definirane stavove o etičkim pitanjima nego učenici. Pretpostavili smo da s
obzirom na aktualnost teme i profesiju kojom se bave nastavnici više
promišljaju o opasnostima na internetu te da imaju čvršće formirane moralne
stavove. Anketa je u većoj mjeri potkrijepila tu hipotezu.
Medicinska geografija
Authors: Kralj Vesna
Published: December 2021

Medicinska geografija
suvremena je znanstvena disciplina koja primjenjuje metodologiju geografije, te
koristi tehnike i koncepte svih disciplina geografije pri istraživanju zdravstvenih problema u prostoru,
proučava i geografsku rasprostranjenost oboljenja, te aktualne novonastale
zdravstvene probleme i bolesti. U sklopu geografije slijedi se stoljetni cilj – razmatranje veze prostor – geografski okoliš – zdravlje.
Korijeni joj sežu u
daleku povijest. Najpoznatiji dokaz je citat Hipokrata, 400 godina prije
Krista. O zraku, vodama i mjestima gdje Hipokrat ukazuje na povezanost okoliša
i kulturnih običaja za zdravljem ljudi. Liječnici iz 18. i 19. stoljeća prvi su
upotrijebili pojam „medicinska geografija“ i nastojali u svojim djelima opisati
i organizirati mnoge nove informacije u kojima se uočava povezanost bolesti,
kultura i okoliša, te su tako nastavljali holističku Hipokratovu tradiciju.
Ovdje ističemo istaknute znanstvenike koji su utemeljili medicinsku geografiju.
To su Jacques Mayer May i Leonhard Ludwig Finke. Finke je namjeravao „stvoriti“
geografsko-povijesno-sociološki“ esej i tiskane karte koje bi bile prve karte
svjetskih bolesti. Medicinska
geografija je ipak suvremena znanost, čiji početak počinje iza 1950. godine. Primjena
metodologije geografije za proučavanje zdravlja, znanosti napreduje koristeći
razne teorije, pristupe, interese i metodologije. Ujedno sudjeluje u brojnim
projektima, te ih i stvara. Utemeljitelj „otac“ suvremene medicinske
geografije, je Jacques Meyer May
(1896. – 1976.), francuski liječnik kirurgije. On smatra da je medicinska
geografija proučavanje o vezi između
patoloških faktora koji je mogu zvati „patogeni“
i geografskih faktora koje je dr. May nazvao, „geogeni“.
Kartiranje (mapiranje) zdravstvenih problema, odnosno unošenje medicinskih
podataka na geografske karte danas je redovita pojava. Prema tematskom području
karte sa medicinskim sadržajem su geomedicinske karte. Medicinska geologija je suvremena znanstvena
disciplina u progresiji koja se bavi proučavanjem utjecaja geoloških materijala
i procesa na zdravlje ljudi, kao i na životinje i biljke, pri čemu se uočavaju
dobri i mogući opasni utjecaji. Elementi u tragovima, bitni za naše zdravlje
posredno ili neposredno potječu iz Zemljine kore. Biometeorologija odnosi se na
sponu vrijeme – klima zdravlje.

Những vấn đề tồn tại trong sản xuất thanh long ở tỉnh Long An và các giải pháp phát triển bền vững
Authors: Nguyễn Tuân , Nguyễn Thị Như Ý
Published: December 2021

Diện tích trồng thanh long của tỉnh Long An đã tăng gấp 5 lần từ năm 2010 đến năm 2014 vượt xa quy hoạch ban đầu của tỉnh trong khi cơ sở hạ tầng và công tác hỗ trợ khuyến nông chưa theo kịp tốc độ sản xuất đã ảnh hưởng lớn đến năng suất và chất lượng sản phẩm, đồng thời dẫn đến tình trạng cung vượt cầu nên giá cả luôn biến động. Để phát triển thanh long ở Long An bền vững trước hết phải quy hoạch lại vùng sản xuất và lựa chọn những giống thanh long phù hợp nhất với địa phương, xây dựng và phát triển thương hiệu thanh long Châu Thành - Long An, mở rộng diện tích canh tác thanh long theo tiêu chuẩn VietGAP, GlobalGAP, nhân rộng các mô hình hợp tác xã sản xuất và tiêu thụ thanh long nhằm nâng cao chuỗi giá trị sản phẩm này.

Kindergarten and School Social Assistance During the COVID-19 Pandemic in Hungary
Authors: Homoki Andrea , Czinderi Kristóf
Published: December 2021

In this paper, we have analyzed the results obtained in the third year of our longitudinal research (2018–2020) regarding the work of kindergarten and school social workers, research conducted in connection with the Hungarian Educational Research Association. The service provided by kindergarten and school social workers was made generally available in Hungary by a legislation change implemented in 2018. By the end of the school year 2018/2019, after initial difficulties, we noticed a positive change in the supportive attitude and acceptance of teachers and public educational institutions towards the work of kindergarten and school social workers. We confirmed an increase in connections to fellow professions as well as in the level of mutual initiative (Homoki & Czinderi, 2020). The continuous development of the service and the reinforcement of professionals is essential as there is a high degree of fluctuation at the national level (Sinka, 2019), even more increased by the effects of the COVID-19 pandemic, posing unprecedented challenges for actors in public educational institutions. Based on our qualitative data obtained by a focus group interview, we have shown how social workers in different types of settlements and educational institutions of the country (N = 13) were ableto adapt to the crisis. What was the degree of fluctuation? What kind of challenges did they face, and what types of resources were they able to mobilize during the online education in the first and second waves of the pandemic? Our data show a shift in priorities at the individual, group, and community levels of social work.
Economic and Higher Education Partnership of Hungary and Kazakhstan
Authors: Mandel Kinga Magdolna , Belgibayeva Anargul
Published: December 2021

The aim of our research was to describe, compare, and analyze the development of business and educational co-operation between Kazakhstan and Hungary over the past 19 years. The research was prompted by the university-level co-operation between the two countries that star ted in 2018, which was made possible by the strategic partnership that is the topic of the present article. We started from the hypothesis that both business and educational co-operation has developed linearly and significantly during the last 19 years. Our research methodology was based on gathering and analyzing secondary macroeconomic, trade, and educational co-operation data in the period between 2011 and 2020. The data were obtained from publications, national offices (statistical, commerce, and education), and international bodies (like TempusPublic Foundation, Eurostat, International Monetary Fund [IMF], and the World Bank). In this paper, we intend to link the main political, social, and macroeconomic endowments with business and educational developments of partnership in the two countries, trying to map out prospects for co-operation. One conclusion is that, although in the political communications of the two countries we were able to identify significant governmental efforts on both sides to support and enforce economic and educational co-operation, the data indicate a decrease in the size of business investments. At the same time, however, the educational co-operation between the two parties continues to develop further.

A Brief Rationale for MMT Arguments
Authors: Tanaka Yasuhito
Published: December 2021

In this note we examine MMT (Modern Monetary Theory) arguments by a simple macroeconomic model without microeconomic foundation. Mainly we will show the following results. 1) In the underemployment case the national income is determined by the budget deficit. 2) In the full employment case we can define the budget deficit which is necessary and sufficient to achieve full employment. 3) The excessive budget deficit causes inflation. 4) We need budget deficit to achieve and maintain full employment under economic growth. 5) We can recover recession by the budget deficit which is larger than that when full employment is maintained. Also, we show that the budget deficit equals the increase in the savings between generations.

Brain skull traumatism: a neurological approach
Authors: Batista Matheus Neres , Sousa Júnior Joel Alves de , Carvalho Lanna do Carmo
Published: December 2021

Introduction: Brain Cranium Trauma (TBI) is defined as any traumatic injury that causes an anatomical lesion or functional impairment of the scalp, skull, meninges, brain or its vessels. In the set of injuries from external causes, the TBI stands out in terms of magnitude and, above all, as a cause of death and disability. Objectives: Demonstrate basic and current concepts in relation to the pathophysiology, diagnosis and treatment of TBI. Methods: The present work is a narrative review of the literature in the PubMed, SciELO and CNBI databases. As search criteria, the following keywords were used: “traumatic brain injury”; “Semiology”; “Neurology” and articles, which were limited to a specific period of 5 years. Exclusion: case reports and inclusion: 12 articles. Results: The main causes of TBI are car accidents, falls, being run over, aggression and sports activities. It was observed that most victims of TBI have subgaleal hematoma (HS), followed by fractures. In mild and moderate TBI, the appearance of HS is more prevalent, 48.5%. In TBI, severe, the incidence of subarachnoid hemorrhage predominates with 71.1% of cases in the first study and 62.5% in the second. Conclusion: The main group affected by TCE are mostly male and young, this predominance is related to the increase in violence with firearms, alcoholism and high speeds in traffic. The elderly group is at risk due to their susceptibility to falls. Children are also prone due to lack of motor coordination, resulting in acidentes.

Published: December 2021

Introduction: Cannabis sativa has several therapeutic properties and has been used for millennials for healing purposes. Among its benefits are analgesic, antiemetic and tranquilizing effects, acting strongly on the nervous system. Objective: This study aims to emphasize the importance of Cannabidiol as a therapeutic purpose for epilepsy, especially in Brazil, where its use is still controlled. Method: A systematic literature review, using bibliographic searches carried out in the electronic databases LILACS, PubMed and SciELO with the descriptors “cannabidiol” and “epilepsy”. Of 1645 searches found, 06 were used in the study. Results: Epileptic seizures can be generalized or partial and are determined by the affected area. The treatment for epilepsy are drugs that decrease the arousal capacity of neural tissue and a significant percentage of individuals cannot control them with traditional drugs alone. Endocannabinoids work in response to epileptiform activity, to activate CB1 receptors for excitatory neurons, to contain excess neuronal activity, which occurs during seizures. It is proven that patients who use it do not have toxic adverse effects. Conclusions: In Brazil, Cannabis is a controlled drug and the fact that it is imported, interfere in the treatment, who is interrupted while patient waits the new dosage. The importance of cannabidiol as a target for research and studies is verified, as it has ample potential in the treatment of epilepsy and reduces brain damage caused by it. In order that patients with epilepsy, have improvements in their quality of life.

Context: The Artery of Percheron (AOP) is an uncommon anatomic vascular variation derivated from posterior cerebral artery segment P1, wich branchs to irrigate bilaterally the thalamus in it is paramedian portion. Amidst vascular cerebral events of the ischemic type, thalamic infarction occour in 11% of the cases. The typical clinical presentation is constituted by the triad: cogniyivebehavior comitente, oculomotors and consience disturbs. Case report: J.F.M.L, 51 years old, male, was found unconscious in his residence by SAMU and then interned in Stroke Room of HGP in 02/06/2020 with a lowered level of consciousness (Glasgow 8). The tests demonstrated a bilateral thalamic infarct due to Artery of Percheron Ischemia. In 02/09/2020 it evolved into a Glasgow 9 being extubated. The CT after 3 days demonstrated absence of bleeding and prophylatically initiated simvastatin, clexane, physiotherapy and phonoaudiology. In 02/15/2020, during physical exam, the pacient was lucid, presented behavior alterations, had left cervical dystonia and ataxia. The patient progressed well and was discharged the next day. Conclusions: The AOP, when occluded, results in bilateral paramedian thalamic and the rostral midbrain infarctions wich may cause diagnosis issues, mainly because of the vast specter of diferential diagnosis. In the presence of triad signals characteritic of bilateral thalamic infarction in CT, it must suspect the manifestation of such entity.
