Published: December 2021

It is important to consider the nutritional demand among genotypes of the same species to achieve high yields. Thus, the objective of this study was to determine the concentration of nutrients in leaves, flowers, grains, and fruit straw in conilon coffee genotypes. The experiment was carried out under a randomized block design, with three replications and the evaluation of nine genotypes. Leaf collections were carried out every three months, from August 2019 to May 2020. Flowers were collected at flowering in July 2019 and fruits in June 2020, upon complete maturation of the genotypes. The materials were dried in an oven and sent for laboratory analysis to determine the nutritional content. Data were subjected to analysis of variance followed by a comparison of means and estimates of genetic parameters and clustering using the hierarchical method (UPGMA). The nutrients found in the highest concentrations in the evaluated plant organs were N and K for macronutrients and Fe for micronutrients. For the leaves, the concentrations of the main nutrients were high in the first and reduced in the last evaluated periods, possibly due to mobilization to the fruits. Considering all the plant tissues evaluated, the order of concentration of macronutrients and micronutrients was N > K > Ca > P = Mg = S and Fe > B > Mn > Cu > Zn, respectively. For a nutritional diagnosis, it is important to take comparisons of the genetic diversity and evaluation periods into consideration.

Published: December 2021

Winter dormancy is an adaptative mechanism that temperate and boreal trees have developed to protect their meristems against low temperatures. In apple trees (Malus domestica), cold temperatures induce bud dormancy at the end of summer/beginning of the fall. Apple buds stay dormant during winter until they are exposed to a period of cold, after which they can resume growth (budbreak) and initiate flowering in response to warmer temperatures in spring. It is well-known that small RNAs modulate temperature responses in many plant species, but however, how small RNAs are involved in genetic networks of temperature-mediated dormancy control in fruit tree species remains unclear. Here, we have made use of a recently developed ARGONAUTE (AGO)-purification technique to isolate small RNAs from apple buds. A small RNA-seq experiment resulted in the identification of 17 micro RNAs (miRNAs) that change their pattern of expression in apple buds during dormancy. Furthermore, the functional analysis of their predicted target genes suggests a main role of the 17 miRNAs in phenylpropanoid biosynthesis, gene regulation, plant development and growth, and response to stimulus. Finally, we studied the conservation of the Arabidopsis thaliana regulatory miR159-MYB module in apple in the context of the plant hormone abscisic acid homeostasis.
‘Pinore’: The New Red Wine Variety Cross-Bred between ‘Pinot Noir’ and ‘Regent’ Vines
Authors: Vršič Stanko , Vršič Klemen
Published: December 2021

Renewed interest in varieties that are more tolerant to diseases has emerged, which is mainly due to increased awareness by producers and consumers regarding the impact of phytochemicals in the environment. This paper describes the first Slovenian grapevine variety ‘Pinore’ crossed between the Vitis vinifera L. ‘Pinot Noir’ clone Mf and ‘Regent’ vines. The aim was to create an early ripening grape cultivar that has a good tolerance to biotic stress (e.g., downy and powdery mildew, botrytis) combined with the benefits of established cultivars and their intense wine colors. Some ampelographic characteristics of young shoots, mature leaves, bunches, and berries are presented, and its major agronomic traits, ripening time, grape yield, quality performances, and disease resistance were evaluated over a three-year period (2014–2017). Wine sensory analyses were performed and compared with the international variety ‘Pinot Noir’. The examined genotype showed good agronomic performance and a high wine quality as far as the content of polyphenols is concerned, especially in terms of anthocyanins and tolerance to diseases (Ren3/9 and Rpv3.1); it is significantly different compared to the reference variety ‘Pinot Noir’. In terms of ampelographic characteristics, the main differences are in the number of leaf lobes, the depth of the lateral sinuses, and the content of anthocyanins in its flesh. The investigated genotype has been proposed to the Committee of new varieties in Slovenia for the variety recognition procedure, and completion of the procedure planned for the end of 2023.

Apricot (Prunus armeniaca L.) is an important temperate fruit crop worldwide. The availability of wild apricot germplasm and its characterization through genomic studies can guide us towards its conservation, increasing productivity and nutritional composition. Therefore, in this study, we carried out the genomic characterization of 50 phenotypically variable accessions by using SSR markers in the erstwhile States of Jammu and Kashmir to reveal genetic variability among accessions and their genetic associations. The genetic parameter results revealed that the number of alleles per locus (Na) ranged from 1 to 6 with a mean Na value of 3.89 and the mean effective number of alleles (Ne) per locus 1.882 with a range of 1.22 to 2. Similarly, the polymorphic information content (PIC) values ranged from 0.464 to 0.104. The observed heterozygosity (Ho) (0.547) was found to have higher than expected heterozygosity (He) (0.453) with average heterozygosity of 0.4483. The dendrogram clustered genotypes into three main clades based on their pedigree. The population structure revealed IV sub-populations with all admixtures except the III sub-population, which was mainly formed of exotic cultivars. The average expected heterozygosity (He) and population differentiation within four sub-populations was 1.78 and 0.04, respectively, and explained 95.0% of the total genetic variance in the population. The results revealed that the SSR marker studies could easily decrypt the genetic variability present within the germplasm, which may form the base for the establishment of good gene banks by reducing redundancy of germplasm, selection of parents for any breeding program.
Large Eddy Simulation of Leakage Flow in a Stepped Labyrinth Seal
Authors: Kim Ji-Hwan , Ahn Joon
Published: December 2021

Large eddy simulation (LES) and Reynolds averaged Navier-Stokes simulation (RANS) of leakage flow in straight-through and stepped labyrinth seals were performed in order to compare their performances in sealing the secondary flow passage of the gas turbine based on the respective discharge coefficients. The results indicate a 17.8% higher leakage prevention performance for the stepped seal relative to that of the straight seal. Further, while the LES predicts an ~7% reduction in the discharge coefficient due to shaft rotation, this effect is underestimated by the RANS. Moreover, the LES correctly predicts a laminarized flow pattern in the clearance, whereas the RANS overestimates the turbulence kinetic energy. In addition, a turbulence kinetic energy spectrum analysis was performed based on the vorticity at selected points in order to identify the flow structure that has a dominant influence on the oscillation of the discharge coefficient. This analysis also enabled identification of the changes in the flow structure due to shaft rotation.

Authors: Baek Jin-Seok , Jo Nak-Beom , Kim Eung-Soo
Published: December 2021

The microwave dielectric properties of β-CaSiO3 glass–ceramics are compared with those of α-CaSiO3 ceramics. β-CaSiO3 is prepared using glass–ceramics method with two-step heat treatment at 730 °C for 1–7 h and at 900 °C for 3 h, and α-CaSiO3 is prepared using conventional solid-state reaction and sintered at 1460–1500 °C for 3 h. With increasing holding time at 730 °C, the degree of crystallisation and Qf of the β-CaSiO3 glass–ceramics increased. The β-CaSiO3 specimens heat-treated at 730 °C for 3 h and 900 °C for 3 h exhibit the following dielectric properties: K = 6.57, TCF = −36.22 ppm/°C, and Qf = 52,400 GHz (highest) for the entire range of heat treatment conditions. The Qf difference between β-CaSiO3 and α-CaSiO3 could be explained by the bond characteristics using Rietveld refinement. FT-IR analysis shows that the Ca–O bond is the dominant factor for the Qf of CaSiO3 ceramics compared to the Si–O bond. The higher Qf of β-CaSiO3 than that of α-CaSiO3 can be attributed to the higher bond strength of Ca–O for β-CaSiO3 than that for α-CaSiO3.

Published: December 2021

The aim of this study was to improve the quality of a vegetable oil, having in view its use as a quenchant for metallic parts in aircrafts. A process of pyrolysis under vacuum was applied to obtain a bio-oil with reduced viscosity and good quenching properties. Preliminarily, the rapeseed oil was fast pyrolyzed at temperature in the range of 300–375 °C and absolute pressure of 1 μbar. Some results such as viscosity and yields of bio-oil were obtained with a narrowing of the temperature range between 300–320 °C, for further processing. Quenching tests with bio-oils on stainless steel 25CD4 showed cooling curves closer to those of the standard mineral oil (Castrol IloquenchTM 1), by comparing them with unprocessed vegetable oil. The hardness of the steel after treatment rose from 29–30 HRC to 43–45 HRC, in accordance with requirements (35–45 HRC). Therefore, the conclusion is that bio-oils obtained by pyrolysis under vacuum are good quenchant proceeds from this study.
The Securitization of Love Jihad
Authors: Malji Andrea , Raza Syed Tahseen
Published: December 2021

The concept of ‘love jihad’ has typically been studied within the context of feminism, nationalism, or religion. However, a singular approach fails to recognize the interconnected impact that each of these has on the development of India’s security policies. This article analyzes how the archetype of the dangerous Muslim male is used to shape India’s securitization strategies. This paper argues that these policies reflect Hindu paranoia of decreasing dominance vis à vis Muslims. This will be explored within three contexts. First, it explores how the perceived threat of an increasing Muslim population shapes state-level and national policies. Second, it explores how the threat of love jihad has shaped India’s policies with its borders and neighboring countries. Third, it examines the international impact of the securitization of love jihad. This paper will demonstrate that at the foundation of these policies is a fear of Muslims strategizing to increase their population via intermarriage and migration. The perceived threat of love jihad has been increasingly utilized as a Hindutva campaign tactic to promote fear and create support for increased securitization policies both domestically and internationally.

Published: December 2021

Replacing fossil energy sources with renewable energy sources is a key strategic action to limit environmental issues. To achieve this goal, substitution with biomass is beneficial due to its versatility in various fields. In terms of circular economy and sustainability, the possibility of energy exploitation of residual biomass is particularly desirable in small-medium enterprises. The use of supply chain by-products can improve sustainability and create opportunities for companies. The purpose of this study is to evaluate the suitability of residual biomass of conifers and broad-leaved trees to produce quality pellets using an agri-pellet machine activated by the power take-off of a tractor. This system can be employed at the farm level. Wood biomass of four species was tested; poplar, stone pine, black locust, and oak. Wood chips samples were analyzed to determine their qualitative characteristics following the technical standard ISO 17225-4. Based on the results, different wood blends were created to produce pellets, subsequently characterized according to ISO 17225-2. The analyses carried out on wood chips and pellets were bulk density, moisture, ash content, calorific value, elemental composition, chlorine, sulfur, and heavy metals. In addition, particles size was measured only for wood chips, while the length, diameter, mechanical durability, and ash melting behaviors were determined only for pellets. Some of the analyzed mixtures show acceptable values according to the current ISO technical standards. The values related to the apparent pellet bulk density and the durability test highlight that not all the mixtures are suitable to produce quality pellets. Results also represent a good starting point for future studies.
Green Aspects of Ion Chromatography versus Other Methods in the Analysis of Common Inorganic Ions
Authors: Michalski Rajmund , Pecyna-Utylska Paulina
Published: December 2021

Due to the increasing environmental awareness of the public, green chemistry has become an important element of environmental protection. In laboratories around the world, millions of analyses of inorganic and organic anions and cations in water and wastewater samples, and solid and gaseous samples are performed daily. Unfortunately, these activities still generate large costs, including environmental costs, which are related to the scale of the studies, the use of toxic chemical reagents, the waste generated, and the energy consumed. The methods used so far for inorganic ion analysis, including classical methods, are increasingly being replaced by instrumental methods, primarily based on ion chromatography. This paper presents the most important advantages and limitations of ion chromatography, and compares them with the costs of classical analyses for the analytes and sample types. Both the financial and environmental costs associated with the determination of common inorganic ions, such as Cl−, NO2−, NO3−, and NH4+, in 1000 environmental samples, were compared using selected reference wet classical methods and ion chromatography. The advantages and limitations of ion chromatography that allow this separation technique to be classified as a green analytical chemistry method have been described herein.

Disinfectants and antiseptics are substances or solvents which play a key role inthe control of infections. Their wide functionality is applied in almost all human activities. Theseagents can have antiviral, antibacterial and antifungal effects. Disinfectants are synthetic agents thebiocidal effect of which destroys microorganisms in the environment, while antiseptics are appliedlocally, primarily on skin and/or mucosae. The morphological differences between Gram (+) andGram (–) bacteria raise questions regarding the biocidal effects of antibacterial agents againstdifferent types of infectious agents. The aim of our study is to evaluate the biocidal effect ofdisinfectants and antiseptics available on the market. The study uses a reference strain ofEscherichia coli and a laboratory isolate of Staphylococcus aureus. The analysis was conductedusing the agar well diffusion method. Results show that sodium hypochlorite, hydrogen peroxideH2O2 and mouthwashing water demonstrate strong bactericidal effect on both Gram (+) and Gram(–) bacteria. The bath cleaner gel, which is considered effective against Escherichia coli,demonstrated effectiveness against Staphylococcus aureus instead. The dishwashing gel,ethacridine lactate, silver water and lavandula water show intermediate or zero effect againstEscherichia coli and Staphylococcus aureus.

Published: December 2021

Relevance. Odontogenic infection is one of the most important problems of dental science. The variety of anti-inflammatory oral hygiene products determines the need for targeted selection of preventive toothpastes and rinses, balms, foams, elixirs, as well as monitoring and training the algorithm of hygienic measures for a patient with an odontogenic infection. The aim of the study was to study the hygienic status of the adult population for the selection of individual oral hygiene products for odontogenic infection, taking into account social and hygienic factors.

Materials and methods. The study examined the prevalence of odontogenic infection in the adult population to determine the need for professional care and dental education. The study involved 198 people without somatic pathology, who were allocated into four groups according to the performed oral care and taking into account the dental status and the intensity of oral microbiota formation in the adult population. The patients were followed-up every week for one month. The study examined the simplified oral hygiene index by GreenVermillion (OHI-S), PMA index and Mühlemann and Son sulcus bleeding index, which allowed calculating the effectiveness of oral care products.

Results. The preventive care effectiveness evaluation showed an increase in the cleansing effect in the adult population over the entire study period. The anti-inflammatory effectiveness analysis demonstrated positive changes: by the end of the study, the PMA index was 51.52 ± 3.40% in group 1; it increased by a factor of 3 and amounted to 44.17 ± 2.77% in group 2; 56.51 ± 4.61% – in group 3, 48.95 ± 3.60% – in group 4. The Mühlemann and Son sulcus bleeding index demonstrated the changes in the periodontal tissue condition and amounted to 52.78 ± 3.62% in group 1, 44.11 ± 3.54% in group 2, 54.97 ± 3.98% in group 3, 47.78 ± 2.73% in group 4.

Conclusions. The development of oral health promotion measures determines the significance of oral care products for the prevention of odontogenic infection in the adult population, which plays a crucial role in the individual program planning for the main dental disease prevention.

Authors: Yakoub D. J. , Startceva I. V. , Admakin O. I. , Solop I. A.
Published: December 2021

Relevance. Skeletal Class III malocclusion is one of the most difficult to correct. Genetics, environmental factors, and postembryonic development influence its etiology. Sagittal expansion of the upper jaw will ensure the correct position of the lower jaw, which in turn will improve the patient's aesthetic parameters and health. The study examines a treatment method using the Fixed anterior growth guidance appliance (FAGGA).

Materials and methods. This clinical case presents a 21-year-old male with skeletal class III due to maxillary bone deficiency. The patient refused surgery to increase the size of the upper jaw and opted for orthodontic treatment. The latter was performed using a Fixed anterior growth guidance appliance (FAGGA), followed by a rapid palatal (maxillary) expansion (RME) and brackets. We removed the FAGGA after eight months. The profile and occlusion improved.

Results. The change in the inclination and protrusion of the maxillary incisors improved the profile. We received 2mm of space behind the upper right canine and 1.5mm of space behind the left one and the SNA angle increased by 2 degrees. The treatment continues with RME and brackets.

Conclusions. An increase in inclination and protrusion of the maxillary incisors and a slight skeletal change improved the aesthetic parameters of the facial area.

Samuel Beckett, la poesía de lo imposible
Authors: Mayet Graciela
Published: December 2021

La escritura poética de Samuel Beckett presenta una percepción extrañada del tiempo. del espacio, de lo real y también una desconfianza en el sujeto y en el lenguaje. La palabra humana no puede dar cuenta de todo aquello, por eso el silencio, el fragmento, el balbuceo, son los recursos del poeta para valerse del lenguaje que es un medio inadecuado para la comunicación, pues su eficacia radica en su carencia. Esta desconfianza en el lenguaje se inicia en la modernidad y se acentúa en la postmodernidad. Filósofos y poetas comparten la idea de que las palabras despiertan percepciones de lo real porque el lenguaje es preocupación para ambos. El lenguaje solo puede ocuparse de una parcela de la realidad; de ahí que muchas veces solo queda el silencio. Beckett intuyó lo que los filósofos descubrieron: la imposibilidad de ir más allá con el lenguaje. La condición humana de un yo fragmentado solo puede percibir lo real fragmentado. Todas estas preocupaciones se hallan en los poemas de Beckett los cuales nos proponemos analizar.

Published: December 2021

Intraoperative confirmation of negative resection margins is an essential component of soft tissue sarcoma surgery. Frozen section examination of samples from the resection bed after excision of sarcomas is the gold standard for intraoperative assessment of margin status. However, it takes time to complete histologic examination of these samples, and the technique does not provide real-time diagnosis in the operating room (OR), which delays completion of the operation. This paper presents a study and development of sensing technology using Raman spectroscopy that could be used for detection and classification of the tumor after resection with negative sarcoma margins in real time. We acquired Raman spectra from samples of sarcoma and surrounding benign muscle, fat, and dermis during surgery and developed (i) a quantitative method (QM) and (ii) a machine learning method (MLM) to assess the spectral patterns and determine if they could accurately identify these tissue types when compared to findings in adjacent H&E-stained frozen sections. High classification accuracy (>85%) was achieved with both methods, indicating that these four types of tissue can be identified using the analytical methodology. A hand-held Raman probe could be employed to further develop the methodology to obtain spectra in the OR to provide real-time in vivo capability for the assessment of sarcoma resection margin status.
O Papel de Stálin e seu Período na Mentalidade Política Russa: uma Discussão Sobre o Complexo Legado do Ditador Soviético
Authors: Da Silva Bezerra Valdir
Published: December 2021

O presente artigo discute o papel de Stálin e de seu período na mentalidade política russa, bem como as razões que vêm levando observadores externos a compararem a Rússia atual ao período Stalinista (1924-1953). Para tanto, inicia-se com uma breve avaliação sobre a figura de Stálin e do ‘Culto à Personalidade do Líder’ como fenômeno, o qual teria retornado à Rússia dos dias atuais no contexto de uma crescente propagandização em torno de Vladimir Putin. Posteriormente, analisa-se a relativa melhora da imagem de Stálin perante os russos nos últimos anos e o papel da celebração anual referente ao Dia da Vitória como elemento de afirmação do papel de Stálin como ‘vencedor’ da Segunda Guerra Mundial. Por sua vez, na terceira parte do artigo, demonstra-se que a imagem de Stálin como ‘repressor’ também está presente na memória coletiva russa, ao contrário do que se pontua no Ocidente, provando, assim, a verdadeira ambivalência do legado do ditador soviético para o país.

Authors: GÜRDAL Aydın Aytaç
Published: December 2021

Most living things need oxygen to survive. However, the consumption of oxygen by cells causes the formation of reactive oxygen species (ROS). In this case, oxygen can have a toxic and mutating effect. It is reported that ROS, which create an imbalance between the antioxidant system of the organism and cause oxidative stress, cause chronic and acute diseases such as cardiovascular diseases, cancer, diabetes, Alzheimer's and some immune problems and aging. Antioxidants are substances that can delay or prevent the damage caused by oxygen in living environments, although they exist in low concentrations. Epidemiological studies report that an antioxidant-rich diet is beneficial and can have a great impact on disease prevention. For this reason, a lot of research should be done on natural antioxidants.
For this purpose, Diospyros kaki (persimmon), Prunus lauroceraus (cherry laurel), Vaccinium arctostaphylos (blue berry) fruits are dried at 60°C and then mixed with ethanol (40°C), hot water (75°C) and warm water (40°C). were subjected to the extraction process and extracts were obtained at the rates of 2.5% and 5%. The DPPH method was used to determine the antioxidant effect. According to the results obtained, the highest antioxidant activity was determined in the hot water extract of the blue berry fruit, and the lowest in the ethanol extract of the cherry laurel fruit. It was observed that increasing the extract concentration slightly increased the antioxidant activity.
martirologio radical. Sentidos de la revolución y la democracia a inicios del siglo XX en Argentina
Authors: Reyes Francisco Jerónimo , Valdéz María José
Published: December 2021

El fenómeno de la sacralización de la política en la configuración de identidades nacional-populares constituye un objeto de estudio instalado en historiografías europeas, pero aún no consolidado en otros ámbitos. Este trabajo ensaya un aporte en esa clave centrado en la interpretación del pasado revolucionario de la Unión Cívica Radical (UCR) en la etapa de su llegada al poder en Argentina, momento en el cual la exaltación de sus muertos como “mártires” de una causa de regeneración se asoció a su éxito electoral y al proceso de democratización. Mediante el análisis de las principales formulaciones intelectuales de esa secuencia histórica, de conmemoraciones ritualizadas organizadas por la UCR a lo largo de una década y media, así como de una serie de acontecimientos particularmente conflictivos, se apela a un conjunto de fuentes que incluye, en especial, a la prensa militante y a la opositora, escritos de más largo aliento e imágenes que ilustran esas instancias. La hipótesis del artículo expresa que ese pasado revolucionario reflejó la popularidad del radicalismo pero luego se tornó particularmente problemático cuando los antagonismos intra y extrapartidarios derivaron en el golpe de Estado de 1930.
Escribir la muerte de Eva: necrológicas y memorias populares en argentina
Authors: Gayol Sandra
Published: December 2021

El artículo analiza cartas de pésame, poesías y composiciones musicales que hombres y mujeres enviaron al presidente Juan Domingo Perón por la muerte de su esposa Eva en 1952. Para comprender cómo se construye una narrativa de dolor por la muerte se presta atención a los lenguajes, objetos y situaciones que estructuraron la escritura, así como a las emociones asociadas con la pérdida. Por medio de las cartas se intentó comunicar y poner algún orden a las experiencias de dolor; narrar el sentir del pueblo como indicador de la fecundidad del lazo político entre los dolientes y el peronismo; o proponer cómo recordar a Eva muerta y quien debería quedarse con la herencia política y emocional que planteaba su desaparición. El corpus de cartas brinda una oportunidad única para explorar cómo algunos hombres y mujeres intentaron dar sentido a un evento histórico crucial para sus vidas, para el peronismo y para la política argentina por fuera del ritual planificado y controlado por el estado.
“Buen gobierno” y militarización de la administración en el Río de la Plata. La trayectoria del virrey Marqués Gabriel de Avilés y del Fierro
Authors: Contreras Emanuel
Published: December 2021

En el presente artículo se reconstruye y caracteriza, a partir de fuentes editas e inéditas, la trayectoria político militar de Gabriel Avilés y del Fierro hasta su nombramiento como virrey del Río de la Plata (1799-1801). En base a ello, nos proponemos analizar cómo distintos elementos constituyentes del ideal de “buen gobierno” atravesaron y justificaron su carrera dentro de la Monarquía Hispánica, inserta en un clima reformista, de guerras entre monarquías y militarización de sus cuerpos políticos.
Juan Manuel de Rosas, “como un eco insondable”. Acerca de algunas apariciones del cintillo punzó en la campaña bonaerense y el extraño caso de las boas coloradas, 1852-1862
Authors: Eujanian Alejandro
Published: December 2021

Analizamos una serie de episodios acontecidos entre 1855 y 1862 en diversos pueblos ubicados a lo largo de la extensa frontera de la provincia de Buenos Aires, en los que las autoridades alertan, acusan y juzgan a paisanos por el uso de la divisa punzó o por dar gritos de “¡Viva Rosas!” en lugares públicos. Nos preguntamos por el sentido de estas manifestaciones y de las acciones desplegadas para reprimirlas, con la intención de responder a la pregunta acerca de cómo operó en diversos espacios una prohibición que fue produciendo una economía moral del recuerdo y del olvido.
La palabra de los otros: maestras denunciadas en las escuelas primarias fiscales durante la segunda mitad de la década del cuarenta
Authors: Ferreyra Gabriela Verónica
Published: December 2021

Este artículo explora los alcances y las limitaciones de los discursos escolares moralistas que contribuyeron a vigilar y regular el comportamiento de las maestras noveles durante la segunda parte de la década de 1940. Desde una perspectiva de género, se revisa la red de significaciones que conformaban la categoría “maestras” desde la mirada del Estado y de la sociedad civil, y se problematiza la referencia al “magisterio” como un bloque homogéneo de experiencia histórica común. El corpus documental está compuesto por una selección de sumarios administrativos pertenecientes al fondo del Consejo Nacional de Educación (CNE).
El “gaucho criollo” y los debates sobre el canon literario. Los premios de la Comisión Nacional de Cultura en la década del treinta en Argentina (1935 -1943)
Authors: Lacquaniti Leandro Gustavo
Published: December 2021

Este artículo estudia las políticas implementadas por la Comisión Nacional de Cultura (CNC) en el campo literario argentino de la década del treinta. Se ocupa especialmente del análisis de los debates sobre el género gauchesco en las sesiones internas de este organismo público y profundiza en los criterios de selección utilizados para la adjudicación de los premios literarios en los concursos promovidos por esta agencia estatal. La hipótesis es que un conjunto significativo de las acciones de la CNC se centró en la promoción y difusión de aquellas obras literarias que representaban al “gaucho criollo”, de componentes mestizos, como emblema auténtico de la cultura nacional.
El campo cultural e intelectual desde la perspectiva del MIR-Praxis (1955-1961)
Authors: Díaz Javier
Published: December 2021

En este artículo analizaremos la forma en que el campo intelectual y cultural fue visualizado e interpelado por el Movimiento Izquierda Revolucionaria (Praxis). Esto nos permitirá contribuir a reconstruir la concepción de esta organización política fundada por Silvio Frondizi y a poner de relieve los motivos de los cambios que aquella sufrió. Para ello determinaremos cuáles fueron las voces que intervinieron en los textos culturales de la prensa del MIR-P, qué diferencias presentaron, qué tópicos fueron transitados, qué tipo de interpelaciones se dirigió a los intelectuales.

Authors: DURAN Mehmet , TEPE Mehmet , DOĞUKAN Mevlüt , TOSUN Fadime , DİREKCİ Aykut
Published: December 2021

Amaç: Son yıllarda artan pediatrik gastrointestinal endoskopi uygulamasında hasta konforu ve işlemin daha kolay uygulanabilmesi açısından derin sedasyona ihtiyaç duyulmaktadır. Bu çalışmadaki amacımız ketamin ve propofol kombinasyonun pediatrik gastrointestinal endoskopide etkinliğini araştırmaktır.
Materyal ve metod: Aralık 2017 ve Mart 2019 tarihleri arasında ketamin ve propofol kombinasyonu ile sedoanaljezi yapılan pediatrik gastrointestinal endoskopi yapılan hastalar tarandı. Hastaların yaşı, cinsiyeti, ek ilaç ihtiyacı, komorbit durumlar, işlemin endikasyonları, meydana gelen komplikasyonlar, işlem süresi, derlenme süresi ve işlem sonrası bekleme süresi kaydedildi.
Bulgular: Çalışmaya 202 erkek, 195 kadın toplam 397 hasta dahil edildi. Ortalama yaşları 9.22±4.72 idi. Vakaların endoskopik ön tanıları incelendiğinde, en yüksek oranda (%53.4) karın ağrısı, ikinci olarak çölyak hastalığı ön tanısı (%15,3) ile alındığı dosya taramasından anlaşıldı. Vakaların işlem süresi 19.77±8.48, derlenme süresi 10.3±3.83 ve işlem sonrası bekleme süresi 17.41±4.19 olarak tespit edildi. Hastaların %20.7’sinda ek propofol ihtiyacı olmuştur. Vakaların,%3.3’nde (13 vaka) komplikasyon görülmüştür
Sonuç: Yaptığımız retrospektif incelemede, 397 hastada propofol ve ketamin kombinasyonu ile başarılı bir şekilde sedasyon sağlanmış olup düşük komplikasyon oranları tespit edilmiştir. Bu nedenle pediatrik gastrointestinal endoskopi uygulamalarında propofol ve ketamin kombinasyonun güvenle uygulanabileceğini düşünmekteyiz

Republikańskie teokracje kalwińskie w Europie
Authors: Wielomski Adam
Published: December 2021

The illiberal democracy is the political system where majority of citizens rule, but where is not the freedom of consciousness or where the liberal dividing of power is absent. In the modern history of Europe the best example of this political system we find in the Calvinist Republics as Geneva, Emden and Netherlands. It’s not the democracy in the contemporary meaning of this word because the notion of “citizen” is aristocratic. The citizens are the members of aristocracy and patricians of towns. But in this time the citizens are the people only. This system is not liberal, because the Catholics are persecuted. The aim of this text is the presentation vision and ideology of theses Republics. It’s the mixture of sovereignty of the people-citizens with the theocratic tendency of Calvinism. In the theory of Calvin, and in the practice of theses Republics we are the tension between the “too swords”: spiritual (Calvinist consistories) and temporal (political power). In the literature we are many of allusions that the theological-political thought of Jean Calvin is inspired by medieval papal theocracy. It’s theocracy with “purified” Word of God, and inspired by the fear of the “caesaropapism”. This fear was just. Every theocratic rule in the Calvinist republican regime is finished by the supremacy of temporal swords. This text present the process of change from papocaesarism to caesaropapism in every republican case.
Problem jeńców radzieckich w czasie II wojny światowej w pamięci i polityce historycznej ZSRR i Federacji Rosyjskiej
Authors: Wojtkowiak Jakub
Published: December 2021

This article deals with the problem of the presence of Soviet prisoners of war during World War II in the memory and politics of memory of the Soviet Union and contemporary Russia. It describes the most important stages of the attitude towards prisoners of war in different historical periods, including in: the Stalinist regime, when they were condemned; the Khrushchev Thaw, when they were rehabilitated; after the collapse of the Soviet Union, when the prisoner-of-war issues appeared in historical debate and culture; and in modern times, when prisoners of war have been pushed to the margins of the politics of memory and memory as an inconvenient problem from the point of view of the current glorification of Stalin and his era.
