Faible littératie et relations complexes aux soins
Authors: CONDETTE Sylvie
Published: June 2023

Les familles vivant dans la précarité parviennent difficilement à se projeter dans un avenir serein même si toutes espèrent que leurs enfants réussiront à sortir de l’impasse. Prenant appui sur deux recherches qualitatives, l’article montre que ces familles, accablées par des problèmes de tous ordres, adoptent des comportements d’adaptation ou de contournement qui les enlisent dans un quotidien toujours un peu plus sombre plutôt qu’ils ne leur permettent de gagner progressivement en autonomie. Dotées d’une faible littératie, ces familles entretiennent un rapport complexe aux soins et aux personnels sociaux et de santé, entre méfiance et incompréhension. Si des choix sont à réaliser dans ce domaine, les parents de ces familles renoncent à se soigner pour accorder la priorité à la santé de leurs enfants à qui ils portent une grande affection. Les services dédiés doivent alors se montrer attentifs à l’ensemble de ces situations singulières, notamment en établissant une communication apaisée et accessible qui fasse sens pour ces familles et qui leur permette de construire un pouvoir d’agir et une capacité à se projeter positivement. Des actions locales semblent particulièrement pertinentes pour créer davantage de proximité, développer un lien social individualisé, bâti sur une relation de confiance et la recherche partagée de solutions.

The Spacialization Revisited: Extensive Type’s Characterization and Contradictions in Theodor W. Adorno
Authors: Andrade João Paulo
Published: June 2023

As Adorno’s posthumous writings were released, a notable turn in his philosophy of music became noteworthy: by revealing an ambitious project on Beethoven, a quasi-axiomatic theory of musical time emerged, which seems to guide adornian thought at very significant works and texts, as Philosophy of New Music. Sketched in three configuration types of musical time, this theory surprises with the so-called “extensive type”. Adorno would then admit kinds of formal consistency (Stimmigkeit) that are not restricted to the ideal of development (Entwicklung) and assumes the possibility of a non-regressive spatialization, which contrasts with his own ontological definition of the medium. This paper discusses the contradictions of extensive type by presenting an analysis of the Archduke Trio op. 97, in the light of the well-known originary affinity between Beethoven and Hegel. At last, the text presents by which means and for what reasons the extensive type would lead Adorno to the last and most decisive modality of musical time’s configuration, the late style.
Foreign body in the gastrointestinal tract as a result of suicide attempt: a case report
Authors: Mehdiyev Elshad S.
Published: June 2023

One of the most common cases in practice is the possession by mentally ill and healthy people of various objects and chemicals for suicide. These observations are interesting; a sick soldier aged 21 years, with suicide intention, swallowed 32 pieces of metal nails, each of which was about 15 cm long.
Taking into account our examinations and observations, for patients with mental illness who have taken foreign bodies for suicide, the type and shape of the objects taken do not play a special role. The intellectual level of individuals who took foreign bodies to commit suicide is not satisfactory. Their actions are the product of primitive thinking.
This observation demonstrates a casuistic clinical case that miraculously did not end in death.
Hipotiroidismo refractario al tratamiento
Authors: Pantoja-Rosero María Elena , Lara-Viáfara Melissa Fernanda , Builes-Barrera Carlos Alfonso
Published: June 2023

Introduction: Refractory hypothyroidism is an entity in which patients require high doses of thyroid hormone, persisting with symptoms of hypothyroidism and high thyroid stimulating hormone (TSH) levels, representing a challenge for the clinician. Understanding its causes allows a better diagnostic approach and avoids overdosage and adverse effects. 
Objective: To present key concepts to help identify the causes of refractoriness to treatment, including adherence, malabsorption, or increased thyroid hormone demand. 
Methods: A search of the main concepts about the causes, diagnosis and treatment of refractory hypothyroidism was performed, according to the review presented at the congress of the Colombian Association of Internal Medicine (ACMI) on May 13 and 14, 2022.
Results: Persistent TSH elevation in patients receiving thyroid hormone supplementation may be present in up to 30% of patients with hypothyroidism. The most frequent cause is poor adherence to treatment, followed by malabsorption and increased demand for the drug. The diagnostic approach should be sequential to find the cause, in some performing specialized studies to rule out malabsorption.
Conclusions: Identifying the causes of refractory hypothyroidism to treatment are key to have an adequate symptomatic and clinical control of the pathology, and likewise avoid the use of supratherapeutic doses of levothyroxine, since it is related to major adverse effects at cardiovascular and bone level.

Relatos de la justicia en perspectiva de género: una mirada al enfoque de género desde la jurisprudencia nacional
Authors: Granados Quiñones María Angélica
Published: June 2023

Estudio de la jurisprudencia de la Corte Constitucional, la Corte Suprema de Justicia y el Consejo de Estado en relación con contextos de discriminación y violencia en los que son víctimas las mujeres en el entorno familiar, con el propósito de determinar si estos contextos o ideas que reproducen estereotipos y promueven la inequidad se han trasladado a la administración de justicia. Es decir, si, a la hora de decidir un caso, los operadores judiciales, además de utilizar el derecho, fundamentan sus fallos en interpretaciones subjetivas que responden a creencias, valores, conductas y expectativas de lo que debería ser el rol femenino en la sociedad o si, por el contrario, deciden teniendo en cuenta la perspectiva de género. Para tal fin, la autora hace un ejercicio de trasladar un texto académico a un escrito con diferentes voces narrativas, en donde se entrelaza la rigurosidad del estudio científico, con la voz femenina de la escritora, para construir una historia que dé sentido a los hechos y que proponga escenarios de debate y reflexión para el lector (a), con el objetivo de desescalar el lenguaje jurídico y técnico de los abogados (as) y permitir la compresión del texto a un público más amplio.

Published: June 2023

Introduction. The peculiarity of the current period development determined the need to change the vector, format and scale of the structural transformation of the Russian economy. This necessitated the need for domestic development only on the basis of achieving technological sovereignty as the main factor of economic growth and a condition of national security. It is revealed that one of the reasons for the low level of its achievement is the low innovative activity of organizations and a small proportion of organizations creating technological innovations and developments in the subjects of the Russian Federation. Theoretical analysis. The article examines the place and role of technological sovereignty in increasing national independence. Various approaches to understanding the essence of technological sovereignty are considered. A retrospective analysis of the “technological sovereignty” category formation is carried out, its priority over the policy of import substitution is proved. Empirical analysis. The analysis of the organizations’ innovative activity indicators dynamics by subjects of the Russian Federation and by types of economic activity, as well as the dynamics of the share of organizations in the total number of surveyed organizations of the Russian Federation engaged in technological innovations is carried out. The results allowed to make a conclusion about the negative trend of most of the indicators’ values. The obtained results confirmed the need to revise the vector of domestic economy development, the research activities activation as the main factor of ensuring technological sovereignty. Results. The result of the study is the identification and systematization of priority areas and measures to ensure technological sovereignty. The specific characteristics of the sovereignties influencing the achievement of universal sovereignty based on the construction of a sovereign economy model are shown. Based on theoretical and empirical analysis, assumptions are made about the different sovereignties level of development in the Russian Federation.
Adsorptive Elimination of Methyl Orange Dye over the Activated Carbon Derived from Bitter Almond Shells. An Isothermal, Thermodynamic, and Kinetic Study
Authors: AL-HYALİ Rana H. , ALKAZZAZ Wael , ALTAMER Duaa H.
Published: June 2023

Abstract: Bitter almond shells (BAS) were inspected as a low-cost precursor in producing activated carbon (AC) through the optimized ZnCl2 activation route. The raw BAS were impregnated with ZnCl2 at multiple ratios (1:1 - 3:1 ZnCl2:BAS), followed by carbonization at various temperatures (400 – 800 °C) for different durations (30 – 120 minutes) in a tubular reactor. The typical AC sample was prepared using a 1:1 ZnCl2:BAS impregnation ratio and activated at 500 °C for 60 minutes. The AC yield under those conditions was 23.46%. The BET surface area (SABET), Boehm titration method, point of zero charge (pHPZC), Field Emission-Scanning Electron Microscopy (FE-SEM), X-ray diffraction (XRD), Fourier Transform Infra-Red spectroscopy (FTIR), and Energy Dispersive X-ray (EDX) of the optimal AC sample were determined. The identification outcomes disclosed that this AC sample is mesoporous with SABET, iodine number, total pore volume, and average pore width of 1221.60 m2/g, 1444.23 mg/g,1.50 cm3/g, and 4.98 nm, respectively. The adsorptive removal of methyl orange (MO) dye from its aqueous phase by this AC was accomplished at various solution pH (2–10), different amounts of the AC (0.05-0.4 g), multiple initial concentrations (50–400 mg/L), variable temperature (10-50 °C) and varied contact time (0–420 min) in a batch- mode operation. The maximum monolayer adsorption capacity of 224.71 mg/g was obtained at 323 K, pH= 2.0, initial (MO) concentration of 400 mg/L, 0.25 g AC dose, and 420 minutes contact time. The kinetic outcomes best fitted to the pseudo-2nd -order kinetics model, while the MO equilibrium capacity obeyed the Langmuir model rather than other models. Thermodynamic studies of the MO adsorption by the BAS-derived AC disclosed that the adsorption was spontaneous and endothermic. The adsorption mechanism of MO by the declared AC mostly involved electrostatic attractions and hydrogen bonding interaction. This work demonstrates that BAS is an advantageous raw material for producing low-cost and effectual mesoporous AC carbon with substantive surface area.

Published: June 2023

This paper presents a synthesis of a sweet almond oil-based trimethylolpropane biolubricant and the evaluation of its temperature-dependent viscosity properties. The oil was converted into biodiesel by the transesterification process after extraction, refining, and acid-alkaline transesterification. After that, biolubricant was produced by further transesterifying biodiesel with trimethylolpropane at 105 oC at a ratio of 3.9:1 for a 60-minute reaction time with a potassium hydroxide catalyst concentration of 1 wt. %. According to the American Standard Test Methods (ASTM), the biolubricant's pour point and index of viscosity were determined to be 267.50 and -4 oC, respectively. The measured viscosities were 42.80, 30.18, 21.39, 12.25, and 8.90 cSt. cSt at 30, 40, 60, 80, and 100 °C, demonstrating an inverse relationship between temperature and lubricant viscosity. The difference between the FTIR spectra of the biodiesel and the biolubricant—1755.74 cm-1 versus 1743.96 cm-1—verifies the ester group. Sweet almond oil has a higher iodine content than unsaturated glycerides (9.52 g of iodine per 100 g of oil sample) and includes 53.478 % more unsaturated fatty acids than saturated fatty acids, and 71.725 % unsaturated fatty acids for biolubricant according to gas chromatographic data. Linoleic acid made up the majority of the fatty acids in the oil and synthetic biolubricant, with percentages of 31.44 and 45.93 %, respectively. Sweet almond biolubricant and oil contained palmitic, linoleic, and oleic acids. The biolubricant has the potential to function as light gear oil for automobiles because its characterization results correlate favorably with the ISO VG-32 criteria
Revista Apuntes Contables. Veinte años aportando en el debate y la visibilización de la investigación contable. Revisión bibliométrica de sus contribuciones
Authors: Católico Segura Diego Fernando
Published: June 2023

El objetivo del artículo es analizar de forma retrospectiva el desempeño de la Revista Apuntes Contables (RAC), y para ello se examinan, bajo un enfoque bibliométrico, las características de los artículos, el perfil de los autores y el impacto de la publicación. La información de la RAC se obtuvo de los archivos dispuestos en su sitio web, y se organizó y analizó en Microsoft Excel y vosviewer. Al examinar la trayectoria de la RAC durante sus dos décadas de existencia (2002-2023) se evidencia que los artículos se caracterizan principalmente por ahondar en asuntos asociados con las áreas temáticas de la contabilidad financiera y las finanzas, así como en la pedagogía y la educación contables. Sin embargo, ha ganado presencia el estudio de la disciplina y la profesión contables en relación con las Tecnologías de la Información y las Comunicaciones (tic), los delitos económicos y el fraude organizacional. El perfil de los autores muestra que la mayor participación es individual, el género no marca diferencia relevante y existe una mayor cualificación. El impacto de la revista ha sido creciente durante los últimos cinco años, aunque inferior al de otras publicaciones locales. El análisis integral hecho a la RAC en sus veinte años de trayectoria muestra su contribución en el campo contable, a la vez que sirve de diagnóstico para el diseño de una estrategia que permita que en el futuro incremente su calidad, pertinencia e impacto.

Food Pantries and Food Deserts: Health Implications of Access to Emergency Food in Low-Income Neighborhoods
Authors: Lee Wonhyung , Jurkowski Janine , Gentile Nicole
Published: June 2023

Access to emergency food is critical for the survival and health of vulnerable populations, but its importance is not understood in the context of food deserts. Using a cross-sectional survey based on Albany and Troy, New York, we compared the two food desert models, one based on paid (e.g., grocery stores) and the other based on free food options (e.g., emergency food sites such as pantries and soup kitchens). Structural equation modeling was conducted to identify pathways among people’s access to food sites, food consumption patterns, food insecurity, and health conditions. Access to grocery stores did not show significant links to food insecurity or health conditions, whereas access to emergency food, especially time taken to such food outlets, was found to be a significant factor for increased consumption of fresh food. Among the diet-related variables, food insecurity showed the strongest link to negative health outcomes. Access to free or low-cost options needs to be taken into consideration when designing research and practice concerning food deserts, food insecurity, and subsequent health effects.
A comparative research study on radical and extremist (hate) speakers in European Member States
Authors: van Ark Rumyana , Boutin Bérénice , Paulussen Cristophe
Published: June 2023

In the context of the proliferation of extremist hate speech in Europe in recent years, legislative provisions have been enacted that inevitably resulted in potentially substantial limitations on the right to freedom of speech. A number of individuals have been subjected to onerous administrative measures in relation to their speech – sometimes after a criminal conviction, sometimes in the absence of criminal law action. Thus, the question of proportionality has inevitably arisen – to what extent can a state legitimately and justifiably restrict the right to freedom of expression in the interests of national security? To put it differently, in respecting its broader social obligation to ensure and preserve security, how much should a state qualify the right to freedom of expression? In addressing these questions, this comparative report will first outline in more detail the applicable international and regional legal obligations and relevant case law in Sections 1 and 2 respectively. Section 3 will focus on the following countries – Belgium, Denmark, Germany, France and the United Kingdom – with particular emphasis on domestic legislative provisions, jurisprudence and national strategies specifically adopted to respond to the risks posed by extreme speakers. It should be noted at the outset that the United Kingdom has legislated against extreme and radical speech within its counter-terrorism legislation. The report will conclude a list of conclusions and closing remarks based on the impact of these domestic practices and legal responses on the right to freedom of expression.
Disfluências e Gaguez: Revisão e Critérios de Referenciação
Authors: Alarcão José , Lucas Isabel , Lapa Lígia , Monteiro Joana , Mota Castelo Teresa
Published: June 2023

A gaguez é uma perturbação da comunicação a nível da fluência em que a pessoa sabe claramente a mensagem que quer transmitir, mas o seu discurso é caracterizado por alterações do ritmo, repetições, prolongamentos, pausas e bloqueios, podendo ainda associar-se a quadros de ansiedade ou tensão emocional. Até uma em cada seis crianças, tipicamente entre os dois e os cinco anos, experienciam um período de disfluência transitória, com habitual recuperação espontânea até à idade escolar, verificando-se uma prevalência de gaguez em até 1% da população adulta, com maior incidência no sexo masculino (4:1). Em Portugal, é estimado que a gaguez afete cerca de 100 mil pessoas, adquirindo particular importância pela sua frequência e associação a redução da autoestima, ansiedade e isolamento social com impacto na capacidade de comunicação do indivíduo e no seu bem-estar e interações sociais. Este artigo tem como objectivo alertar para a complexidade da abordagem diagnóstica e terapêutica em idade pediátrica, com particular incidência na diferenciação entre disfluências normais da fala e perturbação da fluência com início na infância (gaguez) e critérios de referenciação, pretendendo consciencializar e facilitar a deteção e orientação precoce destes casos.

Authors: Souza Flávia Reis Ferreira de , Siqueira Bruno Moreira , Dala-Paula Bruno Martins
Published: June 2023

Os distúrbios relacionados ao glúten, a exemplo da doença celíaca, exigem uma dieta isenta deste ingrediente, que é fundamental durante o processo de panificação pelas suas características tecnológicas altamente desejáveis. No entanto, a demanda por produtos alimentares para fins especiais, isentos de glúten, vem crescendo. Este trabalho teve como objetivo realizar uma revisão bibliográfica acerca da utilização de substitutos aos ingredientes fontes de glúten (trigo, centeio, cevada), abordando aspectos econômicos, de saúde e longevidade, regulamentação, implicações tecnológicas na produção, com destaque para suas vantagens e desvantagens. Apesar do expressivo crescimento do mercado de alimentos sem glúten, o custo ainda é motivo de preocupação. O glúten é um componente essencial em muitos produtos de panificação, podendo ser encontrado naturalmente em alguns (a depender da matéria-prima fonte da farinha utilizada) e também ser empregado como aditivo alimentar. No entanto, há uma variedade de produtos alimentícios isentos de glúten, produzidos a partir de cereais e pseudocereais, como arroz, milho, quinoa painço e amaranto, que não formam o glúten. Além destes, pesquisas recentes vêm sendo realizadas para avaliar o efeito da utilização de farinha de fonio, guandu, semente do fruto do carvalho, fruta-pão, inhame roxo, aveia, dentre outros vegetais como possíveis substitutos à farinha de trigo, centeio e cevada. A produção de alimentos isentos de glúten, com elevada qualidade sensorial e baixo custo, é de suma importância para a garantia de qualidade de vida e longevidade aos indivíduos portadores de doença celíaca ou de outros distúrbios associados ao glúten.

Objective: to conduct the study of age distribution of bone mineral density (BMD) by the database of dualenergy X-ray absorptiometry (DXA) and to compare it with datа of population NHANES study. Material and methods. We used data from the densitometry of three-zone (total hip (TH), femoral neck (FN), and lumbar spine) measured by DXA from two outpatient clinics. The obtained data were compared with NHANES III for TH and FN and with NHANES 2005-08 for lumbar spine. The BMD value was corrected with the calibration coefficient for each DXA scanner. Adjustments were also made for the population distribution by sex and age. Results. Compared with NHANES for FN and TH, the obtained BMD values were significantly decreased for patients aged less than 50 years (men and women). The BMD values for FN and TH were unsignificantly decreased in men older 50 years. In women older 50 years unsignificantly decreased BMD values for FN and a significantly increased BMD values for TH were observed. The BMD values were decreased for lumbar spine in men and women throughout this age interval (more than 50 years old). Conclusion. The population BMD distribution in men and women was assessed by DXA method. The obtained dependence of the BMD for FN in women older 50 years was in good agreement with the results given by Russian and foreign authors.
The Relevance of Osteoscintigraphy Technique in Early Detection of Bone Metastatic Lesions: a Systematic Review
Authors: Litvinenko E. A. , Burova I. V.
Published: June 2023

Background. Due to intensive blood supply to the red bone marrow, as well as high adhesive abilities of tumor cells, bone tissue is a perfect structure for the metastatic process. Timely identification of the pathological process is highly relevant, since data from numerous sources on the use of radiation methods at later stages indicate the development of severe pathological conditions leading to neurological deficiency and significant decrease in a patient’s quality of life. Objective: to summarize data on the diagnostic effectiveness of osteoscintigraphy (OSG), as well as to conduct a comparative analysis of various diagnostic methods in bone metastases detection. Material and methods. The review was performed according to PRISMA standard (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). It included only full-text articles published in the period from 2015 to 2022, as well as particularly important publications from 2005 to 2014. The search for articles was carried out independently using CyberLeninka, eLibrary, Google Scholar, PubMed/MEDLINE databases, by key terms without the use of language restrictions: “osteoscintigraphy”, “radiology’, “tumors”, “bones”, “diagnosis”. Results. The final analysis included 56 scientific articles by a qualitative indicator. The advantages and disadvantages of the methods, as well as indications for the use of various diagnostic techniques in bone metastatic lesions detection were presented. It was shown that OSG will cost 6 times cheaper than positron emission tomography (PET), and 3 times cheaper than magnetic resonance imaging (MRI). The analysis of using radiation methods demonstrated that the specificity of computed tomography and radiography was at a high level, but this techniques had less pronounced sensitivity, and MRI, OSG and PET had greater sensitivity, but insufficient specificity. In the initial stage of the disease, OSG is one of the main methods of metastatic lesions visualization, but not the only way of diagnosis in diversification strategy aspect. Conclusion. OSG is an effective and informative technique for early detection of bone metastases, allowing to assess the functional state of the tumor and its surrounding tissues, even before the appearance of structural disorders visible by other diagnostic methods. To improve the accuracy of the study, it is advisable to use a set of radiation diagnostic techniques. The choice of a particular method is determined by its technical capability and financial availability.
Lorentz Boosts and Rapidity for Inertial Observers in Kruskal-Szekeres Coordinates
Authors: Laforet Christopher
Published: June 2023

The Lorentz boost and rapidity for a radially falling frame are derived for the Schwarzschild metric in Kruskal-Szekeres coordinates. It is found through this analysis that the spacetime is radially length contracted toward the metric source in the falling frame as a result of the Lorentz boosting relative to the rest frame (which is shown to be consistent with the rest frame). When the falling frame reaches the event horizon, the Lorentz boost goes to infinity, causing the falling frame to become light-like, but trapped at the horizon. It is shown that in the falling frame at the horizon, the density of the source goes to infinity as a result of the length contraction.

Authors: Pereira Jackeline da Silva , Santos Marco Aurélio Oliveira , Bandeira Felipe de Lima , Soares Francisco Igo Leite , Vieira Thiago Almeida
Published: June 2023

This study aims to provide a comprehensive analysis of the More Light for Amazon (MLA) program, examining the roles played by each stakeholder involved in the concession process and identifying the limitations faced for program success. The research employs a content analysis methodology, analyzing a variety of documents, including the Program Operational Manual, Commitment Terms, news articles, and concessionaires' notes. The findings reveal the crucial role of the government as an inducer of actions, establishing objectives and guiding norms for the private sector. Conversely, concessionaires assume the role of program implementers but encounter specific limitations in remote locations, challenging the provision and maintenance of the electrical system in beneficiary communities. The implementation of microgrid systems through concessions enhances coordination and integration between generation and distribution services, allowing for increased government control and ensuring transparency, efficiency, and program effectiveness. These identified elements represent significant challenges for the implementation of public policies in remote regions of the Amazon. Overcoming these challenges take coordinated and strategic actions involving both the government and concessionaires to ensure the complete fulfillment of energy needs in MLA program beneficiary communities.

Published: June 2023

In this paper, mesoporous electrodes consisted of Sb-doped SnO2 deposited onto Ti plates controlled corroded under acidic medium were synthesized by spin-coating method, and morpho structurally characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrodes were electrochemical testing in the degradation/mineralization by electrooxidation (EO) of doxorubicin (DOX) as single-component and multi-component together with capecitabine (CCB)-from cytostatic class and humic acid (HA)-from natural organic matter (NOM) class in the absence/the presence of activated carbon (AC) as particulate electrode. The best mineralization efficiency of 67 % was achieved for DOX mineralization using Sb-doped SnO2 deposited onto Ti plate controlled corroded with oxalic acid in electrooxidation process. The presence of AC within the electrolysis process generated a synergy effect of 52.75 % for TOC parameter removal, which is in accordance and quite better than the result reported in the literature. The aspects related to the complex mechanism of DOX degradation and mineralization are discussed. The superiority of AC assisted electrooxidation, as electrochemical filtering (EF), was proved considering simultaneous degradation and mineralization of mixture of doxorubicin, capecitabine and humic acid.
Identification of Climate-Smart Bread Wheat Germplasm Lines With Enhanced Adaptation to Global Warming

Published: June 2023

Bread wheat (Triticum aestivum L.) is one of the world's most important staple food crop providing 20% global energy and dietary proteins. It is widely grown in sub-tropical and tropical areas and as such exposed to heat-stress especially at grain filling period (GFP). Global warming has further affected its production and productivity in these heat-stressed environments. We examined the effect of heat-stress on 18 morpho-physiological and yield-related traits in 96 bread wheat accessions. Heat susceptibility index (HSI <0.60) and yield stability (i <0.55) used as criteria for selecting the tolerant accessions. Heat-stress, imposed by delayed sowing, decreased crop growth and GFP, and as a result reduced morphological and yield-related traits, namely days to 50% anthesis, plant height, peduncle length, flag-leaf area, spike length, spikelets per spike, grain length and width, thousand grain weight (TGW), harvest index and yield. The reduction in the trait values was severe in susceptible accessions (48.2% yield reduction in IC277741) than the tolerant. Physiological traits like chlorophyll content, canopy temperature depression (CTD), normalized difference vegetation index (NDVI), plant waxiness and leaf rolling showed higher expression in the tolerant accessions under heat-stress. Scanning electron microscopy of matured wheat grains revealed ultrastructural changes in endosperm and aleurone cells caused due to heat-stress. The reduction of size and density of large starch granules is the major cause of yield and TGW decrease in the heat-stress susceptible lines. The most stable and high-yielding accessions namely IC566223, IC128454, IC335792, EC576707, IC535176, IC529207, IC446713 and IC416019 were identified as the climate-smart germplasm lines. Germplasm lines possessing desirable traits were selected as po-tential parents for the development of bi-parental and multi-parental populations.

Based on the ERA5 reanalysis dataset of the European Centre for Medium-Range Weather Forecasts (ECMWF), the climatology of the planetary boundary layer height (PBLH) in Jiangsu, China, is studied. The PBLH based on ERA5 is verified by using radiosonde data, and the results show that the PBLH based on ERA5 fits very well with the PBLH diagnosed by the radiosonde data. Overall, the daytime average PBLH is between 700-1200 m, which is higher in the north and lower in the south. It is between 100 and 400 m at night, and it is lower in the north and higher in the south. PBLH exhibits complex spatiotemporal variation. In the daytime, the PBLH in inland areas is highest in spring, followed by fall and summer, and lowest in winter. At night, the seasonal variation in the PBLH is less obvious. The seasonal variation in the PBLH in coastal areas is higher in fall and winter and lower in spring and summer. PBLH shows an obvious diurnal cycle, usually reaching its peak at 14:00 (LST) or 15:00 (LST). The diurnal cycle of the PBLH is significantly positively correlated with the near-surface temperature and wind speed and significantly negatively correlated with the relative humidity and lower tropospheric stability. The daytime PBLH increases significantly in most areas. The increase in PBLH can be attributed to the increase in near-surface temperature and the decrease in near-surface relative humidity and lower tropospheric stability.

The Bayer process is the maim method of alumina production worldwide. The use of low-quality bauxites for alumina production results in the formation of a significant amount of technogenic waste - bauxite residue (BR). The Bayer reductive method is one possible way to eliminate BR stockpiling, but it requires high-pressure leaching at temperatures higher than 220 °C. In this research, the possibility of boehmitic bauxite atmospheric pressure leaching at both the first and second stages or high-pressure leaching at the second stage with the simultaneous reduction of hematite was investigated. Bauxite and solid residue after NaOH leaching were characterized using XRD, SEM-EDS, and Mössbauer spectroscopy methods. The first stage of leaching under atmospheric pressure with the addition of Fe(II) species in a strong alkali solution (330-400 g L–1 Na2O) results in a partial reduction of the iron minerals and an extraction of more than 60% of Si and 5-25% of Al (depending on caustic modulus of solution) after 1 h. The obtained desilicated bauxite was subjected to atmospheric leaching at 120 °C in a strong alkali solution (350 g L-1) or high-pressure leaching at 160-220 °C using the Bayer process mother liquor in order to obtain a concentrate with a magnetite content higher than 83 wt. %.

Companion animals are increasingly being recognized as important contributors to the spreading of antimicrobial resistant bacteria. The present work aimed to measure the antimicrobial drug prescribing in dogs and cats in the Campania region, Italy by analyzing the Veterinary Electronic Prescriptions (VEPs) between 2019 and 2020. The medical records associated with antimicrobial drug prescription were collected considering the drug delivery (systemic or local) and the rationale for the treatment chosen. In the period under investigation, 166879 drugs were prescribed of which 129116 (73.37 %) were antimicrobial. A total of 83965 (65.03 %) antibiotics were prescribed to dogs, 40477 (31.35 %) to cats, and 4674 (3.62 %) to other companion animals. In dogs the 90.48 % of VEPs prescribed for systemic treatment included an antimicrobial Critically Important or Highly Important or Important for human medicine (WHO, 2018). The most widely commonly prescribed class were fluoroquinolones. The main prescribed antimicrobials were the metronidazole-spiramycin (29.71%), amoxicillin-clavulanic (19.58%), enrofloxacin and cephalexin in dogs (16.52 %) and enrofloxacin (22.64%) and amoxicillin-clavulanic acid (21.37 %) in cats. Based on the results the wide use of broad-spectrum or second-line antibiotics is emerged together with the use of the critically important antimicrobials for human medicine.

The novel coronavirus has affected the mental state of the general public, more so among healthcare workers. During the pandemic when the infectivity had become intense, dental professionals were at stake as their work demanded more proximity with oral and nasal secretions. Many dentists had to close their clinics for fear of infection. This had a significant impact on their financial, social and emotional wellbeing. Stress is what arises when something we care about is at stake. Dentistry which is already a stressful discipline, the pandemic has multiplied the already existing pressures of isolation, the focus on perfectionism, compromise on treatment, and time pressures. Our study has attempted to assess the perceived stress among dentists and the various correlates impacting the same. Resilience is the capacity to bounce back productively during stressful situations. Resilience acts like a buffer to wither stress. Resilience is neither permanent nor global. In our study, we have attempted to assess resilience among dentists using a standard validated scale and various sociodemographic factors impacting resilience. Further, we have tried to assess the correlation between stress and resilience. We found that senior dentists with more years of experience had more resilience and their perceived stress was less. Though we found increased perceived stress among women dentists, resilience did not have any gender difference. It is essential to be pandemic prepared with the implementation of resilience-building strategies at various levels.

In the study, it was aimed to develop a valid and reliable scale in order to determine the self-efficacy perceptions of classroom teachers in the field of mathematics learning difficulties. In the development process of the scale, the basic resources and the scale development studies in the literature were examined. First, a pool of substances was created. Content validity was ensured by taking the opinions of 21 expert participants in the 24 question areas determined in the item pool. Content validity index was used in content validity. In this analysis, two questions were removed from the scale. Preliminary application was made with 44 participating teachers who are experts in their fields and exploratory factor analysis was started. For exploratory factor analysis, 359 people consisting of classroom teachers in Sakarya province were studied. In the explanatory factor analysis, 5 items were removed from the scale by looking at the factor load. The factor loadings for the 17 items in the scale vary between 0.508 and 0.976. Among the comparative fit indices obtained as a result of confirmatory factor analysis, RMSEA=0.067 and Cmin/DF=1.568 were calculated. The Cronbach alpha reliability coefficient of the measurements is 0.970. The data obtained were analyzed with statistical methods using SPSS 25, AMOS 24 and Microsoft Excel programs. The validity and reliability criteria of the scale developed within the scope of the study were met.

Published: June 2023

New analytical solutions of the heat conduction equation are presented in cylindrical and spherical coordinates. Then these solutions are reproduced with high accuracy by recent explicit and unconditionally stable finite difference methods. After this, real experimental data from the literature regarding a heated cylinder are reproduced by the explicit numerical methods as well as by Finite Element Methods (FEM) ANSYS workbench. Convection and nonlinear radiation are also considered on the boundary of the cylinder, and it is shown that the explicit methods are much more accurate than the commercial software.
Impact of Cooperation and Intra-Specific Competition of Prey on the Stability of Prey-Predator Models with Refuge
Authors: Pal Soumyadip , Al Basir Fahad , Ray Santanu
Published: June 2023

The main objective of this study is to find out the influence of cooperation and intra-specific competition in escaping predation through refuge of the prey population and the effect of the two intra-specific interactions on the dynamics of prey-predator systems. For this purposes, two mathematical models with Holling type-II functional response function have been proposed and analyzed. The first model includes cooperation among prey populations whereas the second one incorporates intra-specific competition. Existence conditions and stability of different equilibrium points of both models have been carried out for the qualitative behaviour of the systems. Refuge through intra-specific competition has a stabilizing role, whereas cooperation has a destabilizing role on the system dynamics. Periodic oscillations are observed in both the systems through Hopf bifurcation. From the analytical and numerical findings, we conclude that intra-specific competition affects the prey population and continuously checks the refuge class under a critical value, and thus it never becomes too large to cause predator extinction due to food scarcity. Conversely, cooperation leads maximum individuals to escape predation through the refuge so that predators will suffer from low predation success.
