Development Opportunities for the Hungarian Agricultural Startup Ecosystem
Authors: Borda Áron József , Balogh Jeremiás Máté
Published: July 2023

Nowadays, the role of agriculture and the food industry is gradually gaining importance, although it will face many challenges in the future. Digitalisation and newly founded innovative companies can provide solutions to these challenges. The recently established agtech startups could significantly transform the sector. The Hungarian agtech startup ecosystem is a relatively underdeveloped community, but its impact is already notable. The research analyses the characteristics of the Hungarian agriculture technology startup ecosystem and identifies the directions for its future development. Within a qualitative research framework, in-depth interviews were conducted with nine Hungary-based agri-startups, as well as the Hungarian National Chamber of Agriculture TechLab staff members, based on semi-structured questions, between 20 March and 20 April 2021. The results show that there is a good financial environment for Hungarian agtech startups to achieve high performance levels. However, there exist some barriers to success, such as the lack of a culture of failure and relaunch, the low prestige of the agricultural sector, and limited sales capabilities. So far, few Hungarian agtech companies have been able to achieve significant results at the international level. With the advanced digitalisation, the sector is becoming increasingly attractive to young people. The ecosystem’s experience of developing talent management and increased internationalisation over the years can help overcome the limits of the industry. If the startup sector manages to achieve international recognition in the coming years, Hungarian agricultural startups may have a promising future.
Die Annäherung an Möglichkeiten räumlicher Entwicklungen
Authors: Maurer Jakob
Published: July 2023

Es bereitet erhebliche Schwierigkeiten, eine korrekte Übersicht über die Möglichkeiten räumlicher Entwicklung großer Regionen wie Berlin-Brandenburg zu gewinnen. Ständig besteht die Gefahr, Wesentliches zu übersehen und vielleicht Unwichtiges übermäßig zu gewichten. Das gilt besonders für die unangenehmen Grenzen, die knappe Ressourcen setzen, und für unterschwellig sich vorbereitende soziale, wirtschaftliche und politische Prozesse, welche namentlich große Regionen negativ betreffen können. Die Bedeutung der Erkundung wird in der überörtlichen Raumplanung häufig unterschätzt.Es ist deshalb ratsam, ständig, systematisch und realistisch solche Möglichkeiten zu erkunden und sich ihnen anzunähern. Um zeitgerechte Informationen mit einem tragbaren Aufwand zu gewinnen bedarf es einer durchdachten Vorgehensweise und effizienter Methoden; was in vielen Fällen mißachtet wird.

Nuda codzienności w sztuce Marzec Iriny Waśkowskiej
Authors: Charko-Klekot Paulina
Published: July 2023

The article attempts to describe how everyday life and the ennui it entails influence the lives of the protagonists of Irina Vaskovskaya’s play March. The banality of everyday life is one of the main themes in this young author’s works – Vaskovskaya draws portraits of women that are bored and disillusioned with their shallow, bland life, who are waiting for a miracle to free them from the abyss of monotony. The protagonist of the play March stands out against the background of these characters. For her, the trivial everyday life becomes an incentive to abandon her current existence and look for happiness elsewhere (although the actions she takes are often destructive). In the case of the other characters, the lacklustre reality does not spark creativity, but only deepens their passivity and inertia. Vaskovskaya’s play is quite a sombre image of provincial Russia, whose inhabitants live in a state of numbness. While maintaining a semblance of normalcy, they flit between boredom and despair in relation to the meaninglessness of their existence.

Published: July 2023

The importance of STEAM education in preparing students to deal with societal challenges is nowadays an international recommendation. We may find different perspectives concerning STEAM education and the integration of its disciplines. A possible pathway to achieve a balanced integration is through Engineering Design (ED), starting from problems of reality that enable the articulated mobilization of concepts from various disciplinary areas, promoting interdisciplinary where teamwork and context play a fundamental role. This article reports a study with primary preservice teachers (6–12 years old) that aims to analyze the learning displayed and the difficulties underlying the usage of ED in solving STEAM problems. The participants were 45 preservice teachers. We adopted a qualitative methodology, and data were collected through observation, documents, artifacts, and photos. The preliminary results show a very positive reaction of the participants to the experience of solving real context problems collaboratively and mobilizing mathematical and physical science concepts in an integrated way. We identified active engagement, persistence, and motivation in the creation of a model that fulfilled the requested conditions. Difficulties were evidenced in the identification of some concepts and the mobilization of adequate scientific language in the argumentation of decisions.
A study on the larvicidal and adulticidal potential of Cladostepus spongiosus macroalgae and green-fabricated silver nanoparticles against mosquito vectors
Authors: Aziz Al Thabiani
Published: July 2023

Mosquito vectors in the present universe cause a major problem due to the transmission of pathogens with high morbidity. The present research aimed to explore the larvicidal and adulticidal toxicity of the Cladostepus spongiosus extract and its fabricated AgNPs on key mosquito vectors. The synthesized AgNPs were confirmed by UV-Vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectrophotometry, and X-ray diffraction analysis. In the mosquitocidal assay, the C. spongiosus extract has shown good larvicidal mortality against Aedes aegypti (88.9%), Anopheles stephensi (84.1%), and Culex. quinquefasciatus (81.6%). Further, adulticidal mortality percentages were 78.8%, 75.4%, and 67.6% against An. stephensi, Ae. Aegypti, and Cx. quinquefasciatus at 1,000 ppm. AgNPs revealed larvicidal mortality percentages of 94.8% against An. stephensi, 92.8% against Ae. Aegypti, and 90.6% against Cx. quinquefasciatus; the adulticidal potential was also revealed to be higher against An. stephensi (89.4%) followed by Ae. aegypti (86.8%) and Cx. quinquefasciatus (83.2%). Comparing the results achieved from the C. spongiosus extract and its derived AgNPs, promising activity was attained against key mosquito vectors at a minimal dose of 70 ppm of AgNPs. Thus, C. spongiosus-mediated AgNPs can be an alternative tool in controlling key mosquito vectors.

Authors: Xie Hongmei , Song Sijia , Zeng Jia , Zhang Guizhi , Chen Shuang
Published: July 2023

The CeO2 and CeCoO composite oxide catalysts with bimodal mesopore structures were prepared by hard-template method and used for ethanol complete oxidation in air. The physicochemicalphysicochemical properties of the prepared catalysts were characterized by XRD, BET, TEM, XPS, H2-TPR, and O2-TPD. The Co species can be dissolved into CeO2 lattice to form Ce–O–Co solid solution, which promotes reactive oxygen species to be formed on the prepared CeCoO oxide catalysts surface. The bimodal mesopore structures can be obtained by the used hard-template method, and the pore structures of the prepared CeCoO oxide catalysts can be affected by the introduction of Co species. The synergistic effects from bimodal mesopore structures and reactive oxygen species can effectively boost ethanol complete oxidation to final product CO2. The CeCo2 catalyst with Ce/Co mole ratio of 2.0 exhibites superior ethanol complete oxidation activity and service stability, the ethanol oxidation conversion and final oxidation product CO2 selectivity reached 99.8 % and 99.2 % at 200 °C, respectively. This work indicates that the bimodal mesoporous CeCoO solid solution composite oxide catalyst is a promising candidate for OVOCs oxidation elimination from air.

Published: July 2023

Natural fiber composite materials are able to compete with common synthetic materials in situations where the strength-to-weight ratio is important. In this study, we aim to analyze the mechanical, tribological, and surface morphology of composites fabricated from randomly oriented snake grass natural fiber with java plum seed filler. Different weight ratios of fiber to seed filler are chosen: 30:0, 28:2, 26:4, 24:6, 22:8, and 20:10. A 70 % epoxy resin was kept constant in all compositions. The fabricated hybrid composite samples were subjected to tensile, flexural, shear, Shore D hardness, water absorption, and wear tests as per ASTM standards, and the results were compared with those of snake grass mono fiber composites. The 20:10 composite has the maximum tensile strength, impact resistance, flexural strength, hardness, water absorption, and wear resistance compared to other composites. The fiber/matrix adhesion was explored using a scanning electron microscope (SEM). The 20:10 composite shows predominant mechanical and tribological characteristics, making it easier to utilize in structural and automotive applications.

Authors: Gong Chen , Fan Shujie , Yang Bin , Zhang Yu , Ni Jianping , Su Zhenhua
Published: July 2023

The aim of this study was to investigate an effective approach for improving the dissolving pulp properties for making specialty fiber. The caustic and enzymatic treatment of the properties of dissolving pulp was conducted by analyzing the macromolecular structure and chemical composition. The results showed that the enzymatic treatment was more effective on influencing the macromolecular properties, while the caustic treatment had more influence on structural changing, mainly cellulose crystal structure and crystallinity. Meanwhile, to maintain a higher purity and higher brightness, caustic treatment would be beneficial in comparison with enzymatic treatment. The performance of caustic treated sample was evaluated in regarding to chemical composition and acetylation reaction performance, using commercial pulp as reference. The competitive feature of treated sample suggested its potential in future application.
Identification of tuliposides K–M in tulip bulbs via an enzyme reaction-based screening method using a tuliposide-converting enzyme
Authors: Nomura Taiji , Omode Ayami , Kato Yasuo
Published: July 2023

Tuliposides (Pos) are major defense-related secondary metabolites in tulip, having 4-hydroxy-2-methylenebutanoyl and/or (3S)-3,4-dihydroxy-2-methylenebutanoyl groups at the C-1 and/or C-6 positions of d-glucose. The acyl group at the C-6 position is converted to antimicrobial lactones (tulipalins) by an endogenous Pos-converting enzyme. Based on this enzyme activity, we examined tulip bulb extracts and detected HPLC peaks that disappeared following the reaction by the Pos-converting enzyme. Spectroscopic analyses of the three purified compounds revealed that one of them was a glucose ester-type Pos, while the other two were identified as a glucoside ester-type Pos. These compounds were designated as PosK, L, and M. They were specific to bulbs, with the highest content in the outermost layer, but they were markedly less abundant than PosG, the minor bulb Pos we identified earlier. The study results suggest that tulip bulbs contain at least four minor Pos in addition to the major 6-PosA. Although PosK–M were present in almost all of the tested tulip cultivars, they were detected in only a few wild species, indicative of their potential utility as chemotaxonomic markers in tulip. Identification of PosK–M as 6-PosA derivatives unveils the biosynthetic diversity of Pos, the well-known group of secondary metabolites in tulip.
Performance Evaluation for Cohesionless Soil Stabilized with Lignin and Polymerized Lignin
Authors: Zheng Chao , Huang Jie , Bin-Shafique Sazzad , Matamoros Adolfo
Published: July 2023

Lignin is a natural copolymer found in plants that is a major waste from bioenergy and paper industries. In this study, comprehensive laboratory testing programs were carried out to evaluate the strength improvements and water resistance of soil after being stabilized by lignin and polymerized lignin. The chemical polymerization of pre-treated lignin involves a process of linking short lignin molecules to form longer ones and consuming hydrophilic functional groups to improve its stability under wet conditions. Various testing combinations were considered, including four lignin or polymerized lignin contents (0, 6, 8, and 10 %) and four lime contents (0, 2, 4, and 6 %). The results show that lignin-stabilized soil will take at least 14 days to reach maximum strength, whereas the minimum curing period is 21 days for soil stabilized with polymerized lignin. The optimum dosage is 8 % when lignin or polymerized lignin is used for soil stabilization. Polymerized lignin can provide approximately 10 to 20 % more strength improvement than lignin; however, lime seems work better with lignin than polymerized lignin when added as a strength booster. The water soaking tests showed that polymerized lignin has better moisture resistance than lignin, and additional lime can further improve the performance of stabilized soil with respect to water susceptibility. However, the strength of specimens cannot fully recover, decreasing slightly after each dry–wet cycle for both specimens treated by lignin and polymerized lignin. The total decrease is about 5∼10 % after two cycles. The temperature and pH value control and oxygen supply approach used in this study will be an important reference for future studies.
MEMÓRIA E ATUALIDADE: O ACONTECIMENTO DO TERRA À VISTA EM MIM
Authors: Borges Águeda Aparecida da Cruz
Published: July 2023

Este texto me abre espaço para registrar a importância do meu encontro com a obra Terra a Vista, a Análise de Discurso e a professora/autora. Aprendi que o espaço de enunciação é um espaço político de funcionamento e a posição em que enuncio é determinante na minha constituição subjetiva, assim, nesta escrita, a enunciação se constitui a partir do encontro anunciado que se transformou em afeto e em torno de um objetivo: homenagear a prof.ª Eni Orlandi, no sentido de demarcar, o aniversário de 30 anos de publicação do seu livro “Terra à Vista – discurso do confronto: velho e novo mundo”. A leitura desse livro, além de provocar a minha mudança de olhar para os povos originários do Brasil serviu/serve de fundamentos para os estudos que venho desenvolvendo com povos indígenas de algumas etnias, em específico, os Xavante, com quem trabalhei na tese de doutorado. Este texto é atravessado pela memória discursiva e me interpela, pois o modo como esse acontecimento significa em mim se desdobra no movimento de formulações que o constituem.
A ORDEM, CRITERIO Y NÚMERO, REVISTAS CATÓLICAS DE SIGNO VANGUARDISTA
Authors: Cabezas Laura
Published: July 2023

El presente artículo plantea un recorrido por las revistas católicas argentinas Criterio y Número y la revista católica brasileña A Ordem, con el objeto de visibilizar y problematizar la relación, no exenta de tensiones, entre catolicismo y vanguardia. Se ofrece una historización y descripción de las revistas, sus contextos de aparición, sus líneas dominantes y algunos de sus contenidos textuales y visuales. Se busca mostrar que en estas publicaciones culturales católicas, de fines de los años veinte, se produce ese encuentro singular, y hasta impensado para el siglo XX, como parte de un proceso de intelectualización del sentimiento religioso. La hipótesis sostiene que este encuentro entre el discurso católico y los lenguajes modernos del arte y la literatura cuestiona el relato secularizador de la modernidad y, al mismo tiempo, problematiza la oposición radical entre ambos ámbitos, mostrando fundamentos comunes. La filosofía medieval neotomista, base del pensamiento católico, y la estética del retorno al orden, que transitan algunos vanguardistas en ese momento, promueven la necesidad de un mundo más armónico, eterno y objetivo que mire al pasado y confíe en lo divino.
“SOU-ME”: FORMAS DO EU NA ENUNCIAÇÃO LITERÁRIA DO LIVRO DO DESASSOSSEGO
Authors: Cardoso Jr. Vicente de Souza
Published: July 2023

Este artigo pretende analisar a maneira como o enunciador do Livro do Desassossego mobiliza as formas de primeira pessoa em alguns dos fragmentos que compõem essa obra, escrita em prosa por Fernando Pessoa ao longo de duas décadas e atribuída ao semi-heterônimo Bernardo Soares. A base para a análise é a teoria da enunciação de Émile Benveniste e a leitura que o filósofo Dany-Robert Dufour faz dessa teoria, em suas reflexões sobre o dispositivo trinitário inerente às línguas naturais. Entre os resultados, pretende-se mostrar que, na obra analisada, a subjetividade deixa de ser somente uma condição subjacente à enunciação, para ser trazida à tona como objeto, passível de ser manejado na/pela enunciação literária.
FRANCISCO IZQUIERDO RÍOS: UM ESTUDO DE CRÍTICA E TRADUÇÃO
Authors: Nascimento Lilian Pereira
Published: July 2023

Esta pesquisa é uma breve fortuna crítica da obra de Francisco Izquierdo Ríos (1910-1981), autor da Amazônia Peruana, que escreveu sobre seu país, sua região e sua cultura. Com uma produção literária intensa, Izquierdo Ríos ainda é pouco pesquisado e traduzido. Há uma única tradução de sua obra publicada no Brasil, o romance Chove em Iquitos (1975), e por ter sido publicado durante o período militar brasileiro traz algumas discussões sobre crítica da tradução. O supracitado romance apresenta várias limitações tradutórias, como omissão de excertos por causa de temas censurados, desrespeito à linguagem regional, entre outras, para atender o “projeto de nação” idealizado pelos militares. Com Milton (2002) se analisa a política editorial da Clube do Livro, Lambert (2011) é base teórica sobre o modelo descritivo da tradução e Torres (2013) fundamenta questões sobre o perfil do tradutor. Izquierdo Ríos não se esgota no regionalismo, mas ultrapassa-o, principalmente quando atinge as dimensões estética e sociológica próprias da experiência literária.

Este artículo se propone trabajar con las apropiaciones de la noción de “archivo” por la crítica literaria latinoamericana, tanto en sus dimensiones conceptuales o teóricas, como en cuanto espacio concreto de estudios y prácticas de lectura que define una serie de herramientas hermenéutico-metodológicas. Con tal fin, se abordarán una serie de experiencias concretas que serán presentadas como inflexiones del ejercicio de la crítica literaria en su trabajo con diversos archivos de la literatura latinoamericana. En primer lugar, se realizará un breve repaso por el enfoque crítico-editorial que dio origen a la Colección Archivos, para a continuación abordar los trabajos de Ana María Barrenechea y Rolena Adorno con los manuscritos de Julio Cortázar y Felipe Guaman Poma de Ayala, respectivamente. Se concluirá con algunas consideraciones en torno al actual “giro archivístico” de la crítica latinoamericana y sus encrucijadas contemporáneas.
ARTE-FATO NUCLEAR: REVISTAS CULTURAIS E LITERÁRIAS BRASILEIRAS DO FINAL DOS ANOS 1970. CAMINHOS DA CRÍTICA
Authors: Fonseca Claudia Lorena
Published: July 2023

As revistas literárias e culturais são o espaço por excelência da discussão acerca do literário, exercendo papel determinante naquilo que diz respeito tanto à divulgação de novos autores; quanto à reflexão crítica. Tradicionalmente fundadas por grupos de intelectuais, essas publicações se constituem em veiculo de difusão de seu pensamento, de ideias e correntes, e das mais diversas concepções artísticas. De um contexto, em suma. Em determinados períodos históricos sua importância se intensifica, caso das revistas que circularam durante o período de vigência da ditadura civil-militar no Brasil, por exemplo. Neste estudo, nos dedicamos a três destas revistas: Anima, Através e Arte em Revista, todas elas surgidas na segunda metade dos anos 1970. Nosso objetivo é lançar um olhar apurado sobre um aspecto em especial: o exercício da crítica literária e as relações entre intelectuais brasileiros, além da relação destes com a crítica latino-americana. Que correntes teórico-críticas promovem? Constituem-se estas em um pensamento próprio ou bem de divulgação de correntes que estão em evidencia nos grandes centros de Europa e América do Norte? São necessariamente vanguardistas? Essas são algumas das questões que buscamos responder a partir de nosso trabalho. Para tanto, nos valemos dos estudos de diferentes teóricos que trataram do fenômeno Revistas, como Beatriz Sarlo, Pablo Rocca, Horacio Tarcus e Maria Lucia Camargo, entre outros.
Monoacylglycerol Lipase Protects the Presynaptic Cannabinoid 1 Receptor from Desensitization by Endocannabinoids after Persistent Inflammation
Authors: Bouchet Courtney A. , McPherson Kylie B. , Coutens Basile , Janowsky Aaron , Ingram Susan L.
Published: July 2023

Cannabinoid-targeted pain therapies are increasing with the expansion of cannabis legalization, however, their efficacy may be limited by pain-induced adaptations in the cannabinoid system. Cannabinoid receptor subtype 1 (CB1R) inhibition of spontaneous, GABAergic miniature IPSCs (mIPSCs) and evoked IPSCs (eIPSCs) in the ventrolateral periaqueductal gray (vlPAG) were compared in slices from naive and inflamed male and female Sprague Dawley rats. Complete Freund's Adjuvant (CFA) injections into the hindpaw induced persistent inflammation. In naive rats, exogenous cannabinoid agonists robustly reduce both eIPSCs and mIPSCs. After 5–7 d of inflammation, the effects of exogenous cannabinoids are significantly reduced because of CB1R desensitization via GRK2/3, as function is recovered in the presence of the GRK2/3 inhibitor, Compound 101 (Cmp101). Inhibition of GABA release by presynaptic μ-opioid receptors in the vlPAG does not desensitize with persistent inflammation. Unexpectedly, while CB1R desensitization significantly reduces the inhibition produced by exogenous agonists, depolarization-induced suppression of inhibition protocols that promote 2-arachidonoylglycerol (2-AG) synthesis exhibit prolonged CB1R activation after inflammation. 2-AG tone is detected in slices from CFA-treated rats when GRK2/3 is blocked, suggesting an increase in 2-AG synthesis after persistent inflammation. Inhibiting 2-AG degradation with the monoacylglycerol lipase (MAGL) inhibitor JZL184 during inflammation results in the desensitization of CB1Rs by endocannabinoids that is reversed with Cmp101. Collectively, these data indicate that persistent inflammation primes CB1Rs for desensitization, and MAGL degradation of 2-AG protects CB1Rs from desensitization in inflamed rats. These adaptations with inflammation have important implications for the development of cannabinoid-based pain therapeutics targeting MAGL and CB1Rs.

SIGNIFICANCE STATEMENTPresynaptic G-protein-coupled receptors are resistant to desensitization. Here we find that persistent inflammation increases endocannabinoid levels, priming presynaptic cannabinoid 1 receptors for desensitization on subsequent addition of exogenous agonists. Despite the reduced efficacy of exogenous agonists, endocannabinoids have prolonged efficacy after persistent inflammation. Endocannabinoids readily induce cannabinoid 1 receptor desensitization if their degradation is blocked, indicating that endocannabinoid concentrations are maintained at subdesensitizing levels and that degradation is critical for maintaining endocannabinoid regulation of presynaptic GABA release in the ventrolateral periaqueductal gray during inflammatory states. These adaptations with inflammation have important implications for the development of cannabinoid-based pain therapies.

Sculpting with the Sun
Authors: Lagarde Patricia
Published: July 2023

In the ancient Peruvian highlands, architecture and sculpture were inextricably linked to the mountainous Andean landscape. The character of light in this environment and how it illuminates architectural sculpture can fundamentally alter the way we perceive these objects. The dimensionality and placement of the tenon heads and cornice stones at Chavín de Huántar offer a unique opportunity to understand the role of the natural environment within architectural programs. Through a discussion of the sun’s role in casting dramatic shadows in the stones at Chavín, this article shifts our focus from object to shadow and demonstrates the powerful visual effects intended for individuals approaching the site. Utilizing the strong highland sun, sculptors leveraged the shadow-producing effects of these three-dimensional pieces to create spectacularly ornamented buildings. Although these vistas are lost today, archival photographs provide glimpses of the original perspectives. The sun generated movement of otherwise static sculptures, animating the heads mounted within the walls. Utilizing phenomenology of light, this paper positions the sculptures at Chavín within a cross-cultural dialogue on the role of natural light in the built environment. Together, the sculptures with their shadows animated the structure and focused the viewer’s attention on the monument from afar.

Mitochondrial biogenesis is the process of generating new mitochondria to maintain cellular homeostasis. Here, we report that viruses exploit mitochondrial biogenesis to antagonize innate antiviral immunity. We found that nuclear respiratory factor‐1 (NRF1), a vital transcriptional factor involved in nuclear‐mitochondrial interactions, is essential for RNA (VSV) or DNA (HSV‐1) virus‐induced mitochondrial biogenesis. NRF1 deficiency resulted in enhanced innate immunity, a diminished viral load, and morbidity in mice. Mechanistically, the inhibition of NRF1‐mediated mitochondrial biogenesis aggravated virus‐induced mitochondrial damage, promoted the release of mitochondrial DNA (mtDNA), increased the production of mitochondrial reactive oxygen species (mtROS), and activated the innate immune response. Notably, virus‐activated kinase TBK1 phosphorylated NRF1 at Ser318 and thereby triggered the inactivation of the NRF1‐TFAM axis during HSV‐1 infection. A knock‐in (KI) strategy that mimicked TBK1‐NRF1 signaling revealed that interrupting the TBK1‐NRF1 connection ablated mtDNA release and thereby attenuated the HSV‐1‐induced innate antiviral response. Our study reveals a previously unidentified antiviral mechanism that utilizes a NRF1‐mediated negative feedback loop to modulate mitochondrial biogenesis and antagonize innate immune response.

The issue of ethics in research involving children has become a significant concern for researchers. This situation pertains to obtaining consent and conducting recruitment during and after the study, while ensuring the safety and well-being of the children involved. This investigation aims to identify ethical challenges in child studies across different countries. The study explores the application of research ethics in various nations and highlights the ethical predicaments that arise when conducting research with children, specifically concerning upholding their rights. Furthermore, the study uncovers that the interplay of cultural, social, economic, and political contexts can complicate adhering to ethical standards and protocols. Additionally, it notes that power dynamics between children and adults may create an unequal footing for child participants in research. In light of this, the study stresses the importance of considering children’s opinions and involvement, particularly in the context of their education and welfare, to protect their rights. It also underscores the need to prioritize children’s emotional well-being, which can have significant implications for bullying, body image, relationships with friends and family, and other areas that demand high sensitivity.

Published: July 2023

Ponad 20-letnia recepcja Madame Antoniego Libery pozostaje bez precedensu. Jej unikalność polega na równoczesnym i intensywnym funkcjonowaniu utworu w trzech kręgach odbiorczych: profesjonalnym, nieprofesjonalnym oraz szkolnym (od 2018 roku to obowiązkowa lektura w szkołach ponadpodstawowych). Obecność Madame w obiegu krajowym podkreślają wskaźniki liczbowe: 150 tys. nakładu, drugie miejsce w plebiscycie 20-lecia. Powieść reprezentuje polską prozę za granicą: przełożono ją na ponad 20 języków, jest finalistką IMPAC oraz francuskiej nagrody europejskiej. Aby zrozumieć, w czym tkwi magnetyczna tajemnica utworu, który już za życia autora uzyskuje status arcydzieła, należy omówić kilka zagadnień: warstwy interpretacyjne (romans, obraz Polski gomułkowskiej, natura mitu), ukształtowanie języka (heksametr), kompozycję (powieść w powieści, echa i refreny), wielogatunkowość utworu oraz kreację narratora.

The analysis of the problem of interrelation of personal features and transgressive behavior in candidates for service in law enforcement agencies is presented in the work. The results of empirical research of 70 respondents-candidates for service at the age of 19–39 years old differentiated into two empirical groups: EG-1 (N = 35) – candidates for the post of police commissioner and EG-2 (N = 35) – candidates for the post of traffic police inspector. A comparative analysis of the studied parameters using U-Mann – Whitney criterion was conducted. It was found that EG-1 subjects differed in manifestation of “civic sphereˮ, “productivityˮ, and “speedˮ indicators. The test subjects of EG-2 surpassed the test subjects of EG-1 by the parameter “rigidityˮ. The correlation between personality traits and transgressive behavior was revealed using the rs-Spearman correlation analysis. It is shown that the configuration of the parameters of personality traits and transgressive behavior in each empirical group is different.

The article presents the practical aspects of studying the formation of communication skills of younger schoolchildren with mental retardation in the process of extracurricular theatrical activities. The specifics of the phenomenon of communication skills and the influence of theatrical activities on their formation are analyzed. In the course of the pilot study, it was found that at the ascertaining stage of the experiment, children of primary school age with mental retardation showed low levels of communication skills, indicating insufficient communicative competence, ineffective communicative interaction, insufficiently developed activity in the field of displaying and transmitting action landmarks: In order to form communication skills among younger schoolchildren with mental retardation, a program was developed that consists of three stages: preparatory, main and final. At the control stage of the experiment, the indicators of the development of communication skills became higher in the experimental group, which indicates the effectiveness of the use of the psycho-correction program by means of theatricalization, aimed at increasing the communication skills of children of primary school age with mental retardation.
Effects of injection temperature on mechanical properties of bagasse/polypropylene injection molding composites

Effects of injection temperature on thermal degradation and porosity of the bagasse/polypropylene injection molding composites were studied. Above 185 ºC, incomplete filling occurred. The incomplete filling increased with increase of injection temperature. It was found that the gas generated by thermal degradation of bagasse fibers was so accumulated in the injection cylinder that the injected composites ended up with incomplete filling. A modified injection method with the venting of gas increased the complete filling percentage. Mechanical properties decreased with increase of injection temperature from 165 ºC to 260 ºC. This was due to increase of porosity and fiber shortening. The calculated flexural modulus, which incorporated the effect of porosity and fiber length, agreed well with the experimental results. Composites with maleic acid anhydride grafted polypropylene (MAPP) were also investigated. Flexural strength and impact strength were improved by 45% and 35%, respectively, by addition of 20wt% MAPP. In the MAPP composites, fiber breakages at their roots were observed in the fracture surface after an impact test, while pulled-off fibers were observed in those without MAPP.

A pyrolysis tube furnace system was designed to assess the impact of different components on pyrolysis characteristics under nitrogen atmosphere, and pyrolysis temperature (400 to 900oC) as important factors acting on the samples during pyrolysis. The obtained pyrolysate was classified into three groups, i.e. the condensed liquid product (bio-oil), solid product (bio-char), and light gas. Gas chromatography (GC) was used to analyze ingredients of the light gas released during pyrolysis, and a gas chromatography/mass spectrometer (GC/MS) was used to analyze bio-oil. The results revealed that the volatiles from rice straw pyrolysis exceeded that from lignin at temperatures below 700oC as a result of the higher char generation from lignin pyrolysis. With an increase of pyrolysis temperature, the yield of char decreased and light gas persistently increased, and the yield of bio-tar was maximized at 500oC. In the gas product, H2, CO, CO2 and some light hydrocarbons (CH4, C2H4 and C2H6) could be found, and H2 and CO were abundant. Compounds of bio-oil derived from lignin were simple and consisted of aromatic hydrocarbons, chain hydrocarbon, monoaromatics, and a minor amount of ketones. Phenolic compounds, which comprised 50 to 60%, can be converted easily to obtain high-value chemicals and high quality biofuels.

It is difficult to use lignin in any analytical methodology without reducing its considerable polydispersity by fractionation. An ammonium lignosulphonate sample was fractionated using a method of partial solubility in solutions of isopropanol increasingly diluted with distilled water, effectively fractionating by polarity. Selected fractions were characterised by gravimetric determination of the fractions, and determination of acid insoluble lignin, soluble lignin, and carbohydrate contents. Acid-insoluble lignin content was very low, and soluble lignin provided the majority of the lignin content, as should be expected from sulphonated lignin. Carbohydrate contents were also fairly low, the highest percentage at 14.5 being in Fraction 2, with the bulk lignin and Fraction 3 having 6.5% and 3.2%, respectively. Differences in the composition of each fraction support the efficacy of the fractionation process and permitted selection of fractions for use in subsequent studies.

Nutrition is the most relevant and important topic to be dealt with in the present situation. Making adolescents eat healthy foods at times feels like an uphill task. However, in the long run, it is important as children need proper nutrients to stay healthy and grow strong. Adolescents are usually choosy about food, however food preferences can be developed through consistent exposure to a variety of foods. Globalization has made a major impact on food systems around the world. In present times, factors like fast-paced life, increasing nuclear families etc, have led to more dependence on fast food and ready to eat foods. Ethnic foods originate from the heritage and culture of an ethnic group that uses its knowledge of local plants and/or animal sources that can substitute fast foods like ketchup, jams, jellies, candies, mayonnaise etc. In the southern part of India, there are traditional foods which are natural, nutritious and delicious. This paper intends to bring out the richness of traditional South Indian foods. Itaims to throw light on many such traditional Indian recipes like Chutney Pudi, Unde which are not popular like other condiments and snacks. Some of the recipes are easy to prepare, nutritious, tasty and have a long shelf which can be usedas substitutes for sauce and jams. This is a humble attempt to communicate the wealth of culinary knowledge of Indians on traditional foods for the betterment of humankind all over the planet.
