Published: January 2023

Background: The article presents experimental studies conducted on Wistar rats in the amount of 50 individuals. An artificial gum recession defect was created.

Aim: to evaluate the effectiveness of creating a gum recession model in the proposed way.

Material and methods: Experimental animals at the beginning of the study had an intact oral mucosa: pale pink color, without pathological changes. An experimental model of gum recession was created by excision of V-shaped periodontal tissues from the vestibular surface in the area of the lower jaw incisors of a rat, then a DispodentPak No. 000 retraction thread was applied in the area of the lower central incisors in the circular ligament of the tooth to a depth of 1.5 mm, and Vitrebond dental glass ionomer cement was applied to the vestibular surface of the neck of the tooth of the lower incisors, with at the same time, prednisone is administered intramuscularly at the rate of 12 mg / kg of animal weight on the 1st, 3rd and 5th day. For the experiment, female white rats in the amount of 50 individuals were used as a model. All animals were divided into 2 groups depending on the method of creating a gum recession defect. In the control group of rats, the defect was created according to the standard procedure by conducting a V-shaped incision.

Results: When creating the proposed model of experimental gum recession, the clinical and pathomorphological picture is achieved under the influence of local factors: V-shaped gum incision, retraction thread, dental glass ionomer cement. To suppress the processes of self-regeneration of the gums, the optimal dose of prednisone is administered.

Conclusions: On the 3rd day of the experiment, a V-shaped defect was observed in animals. On the 10th day, clinical signs of gum recession are determined: a defect with a depth of 2 mm. The average depth of recession in animals was (2 ± 1.7 mm). A relatively short process of modeling a gum recession (no more than a month). In this case, a local lesion of the gum is created, not burdened by any other pathology in the animal, and having both local and general (stress) pathogenetic factors, against the background of changes in the reactivity of the organism, which corresponds to the modern theory of the occurrence of recession as a polyethological disease in humans.

Miejsce w biografii jako wyraz wspólnego świata
Authors: Mendel Maria
Published: January 2023

W eseistycznej formie autorka daje wyraz zainteresowaniu miejscem w biografii, postrzeganym z perspektywy pytania o świat wspólny, współtworzony nie tylko przez ludzi. Pokazuje, jak obecność miejsca w biografii przypomina o tym świecie oraz zakrywającej go dychotomii Natura–Kultura. W odniesieniu do myśli, która podważając tę dychotomię odchodzi od pojęcia Natury (jak koncepcja „ciemnej ekologii” Timothy’ego Mortona) i opierając się na materiale literackim –Przewóz Andrzeja Stasiuka – argumentuje swoją tezę o miejscu w życiowej opowieści. Warunkując możliwość snucia opowieści o życiu, miejsce jest w niej oknem na symbiotyczną rzeczywistość; świat, który nie jest wyłącznie ludzki. Konkluzje aktualizują pedagogikę miejsca, akcentując potrzebę jej zorientowania na kultywowanie świata wspólnego i nowe, regeneracyjne myślenie o uczestnictwie człowieka w życiu i trwaniu tego świata.
Biografia i doświadczenie miejsca w kontekście współczesnych wydarzeń. Zaproszenie do refleksji
Authors: Kaźmierska Kaja
Published: January 2023

Artykuł jest refleksją nad znaczeniem miejsca w biografii w kontekście kultury współczesnej oraz ostatnich wydarzeń globalnych – pandemii i wojny, stanowiących ramę dla doświadczeń biograficznych. W odniesieniu do pierwszego aspektu wskazane są cechy kultury współczesnej unieważniające znaczenie miejsca jako stałego punku odniesienia w biografii. Z kolei doświadczenie pandemii i zapośredniczone doświadczenie wojny w Ukrainie analizowane są jako czynniki wymuszające (re)definicję relacji między miejscem i biografią oraz przepracowanie doświadczeń sformatowanych przez współczesność. Artykuł jest wstępną propozycją zmierzenia się z tą problematyką. Wymaga ona podjęcia systematycznej eksploracji również w polu badań biograficznych.
Las miejscem życia partyzantów oddziału „Ojca Jana”
Authors: Sabat Katarzyna
Published: January 2023

Działalność oddziału Franciszka Przysiężniaka ps. „Ojciec Jan” przypada na okres drugiej wojny światowej. Głównym miejscem stacjonowania konspiratorów były Lasy Janowskie położone w północnej części Kotliny Sandomierskiej. Celem artykułu jest przedstawienie znaczenie lasu jako miejsca egzystencji partyzantów „Ojca Jana” – w głuchych odstępach leśnych organizowano życie konspiracyjne, formowano postawy patriotyczne, zagrzewano do walki z wrogiem, a także rozmyślano o przyszłości po zakończeniu działań wojennych. Przyroda, którą byli otoczeni partyzanci wymagała przystosowania się do niej i jej dogłębnego poznania, co odzwierciedlają zachowane wspomnienia świadków tamtych czasów.

Between Fear and Hope: The Privatization of Government Higher Education Institutions in Saudi Arabia and the Role of Leadership in Managing Change
Authors: Shafai Areej
Published: January 2023

The purpose of this paper is to provide an analysis of privatization as it applies to public universities and colleges in the Kingdom of Saudi Arabia. It also aims to critically reflect on the expected concerns due to the new environmental change resulting from the implementation of privatization and its impact on performance. There is a scarcity of existing literature on how privatization affects employee performance, and whether or not employees remain competent in their new environment. This paper also focuses on the significant role of leadership as organizations transition from public organizations to privatized ones. An in-depth content analysis of the privatization of public Saudi higher education institutions was adapted as a methodological approach to this study. Through this approach, the gap that exists between the new transformations, the leadership required, and the necessary preparations for privatization were analyzed. The major findings indicate that the idea of privatization in and of itself constitutes a great fear and anxiety for employees due to the organizational, administrative, and cultural change that privatization may bring. Higher education institutions are in dire need of influential and visionary leaders who can manage and facilitate the privatization process to ensure its success and achievement of the desired goals. The paper explores the nature, potential consequences, and concerns of privatization. It highlights the importance of leadership as a fundamental pillar of change.

Published: January 2023

Atomic force microscopy (AFM) is highly regarded as a lens peering into the next discoveries of nanotechnology. Fundamental research in atomic interactions, molecular reactions, and biological cell behaviour are key focal points, demanding a continuous increase in resolution and sensitivity. While renowned fields such as optomechanics have marched towards outstanding signal-to-noise ratios, these improvements have yet to find a practical way to AFM. As a solution, we investigate here a mechanism in which individual mechanical eigenmodes of a microcantilever couple to one another, mimicking optomechanical techniques to reduce thermal noise. We have a look at the most commonly used modes in AFM, starting with the first two flexural modes of cantilevers and asses the impact of an amplified coupling between them. In the following, we expand our investigation to the sea of eigenmodes available in the same structure and find a maximum coupling of 9.38 × 103 Hz/nm between two torsional modes. Through such findings we aim to expand the field of multifrequency AFM with innumerable possibilities leading to improved signal-to-noise ratios, all accessible with no additional hardware.

Rapid tooling using additive manufacturing, or 3D printing, is an emerging manufacturing technology that has the potential to revolutionize the production of complex parts using only a computer and a design program. Lightweight structures with excellent dimensional precision and lower cost for customizable geometries are possible with these printed parts. In recent years, inherent constraints of polymers, metals, and ceramics have pushed researchers toward superior alternative composite materials to boost mechanical and other critical features; current 3D printing research follows this route from neat to composite materials. The characteristics, performance, and future uses of composite materials produced using additive manufacturing methods are discussed in this review. In addition, to discuss the state of the art in additive manufacturing, this article also fabricated many technologies, including robotics, machine learning, organ-on-a-chip, and 4D bioprinting.
Factors affecting firmness loss in apples during postharvest handling and cold/controlled atmosphere storage in India: A review
Authors: Damarla Ramesh Babu , Rao K.V. Narasimha
Published: January 2023

Apples attract humans with their dominant appeal and eating quality. The most dominant properties are color and texture. This review paper discusses the scientifically published results of apple texture through understanding internal properties like structural, physiological, physical, mechanical, water and cell wall contributions and post-harvest handling and storage methods. A critical appraisal is made of factors responsible for inner texture and sustenance during post-harvest and storage periods. The status of research data available is discussed from a firmness point of view of Indian apple varieties vis-à-vis those grown in other countries. Most of the research work on Indian apples reported physico-chemical parameters like weight, diameter, firmness, bio-chemical and nutrient components. The latest literature did not find data for the long term behaviour in CAS (6 to 10 months). The research data on factors responsible for texture loss is also very limited for Indian-origin apples. There are still large gaps in research on firmness loss in apple. Hence, suggestions are made on the scope for future research on apples grown in India for the benefit of farmers, traders, and consumers.

Authors: Manjunath B.L. . , Upretti K.K. . , Laxman R.H. . , Radha T.K. . , Raghupathi H.B. .
Published: January 2023

A field experiment to standardize the partial root-zone drying irrigation in papaya (Carica papaya L.) cultivar ‘Red Lady’ indicated that replenishing 70 % of the evaporative demand and changing the irrigation sides once in 12 days stored higher soil moisture (14.6 %) in the root zone. Irrigation meeting 60 % ER found to enhance the photosynthetic rate (13.9µ mol/m2/s) significantly, while shifting the irrigation at 16 days was found to reduce the rate (9.9 µ mol/m2/s). ABA production increased with an increase in the interval between the changing irrigation sides. Vertical growth of roots was significantly higher (67.3 cm) when irrigation was scheduled meeting 60 % pan evaporation with irrigation side changing once in 16 days. Replenishing 60 % of evaporation recorded significantly higher number of fruits (46.1/plant) and further changing the irrigation sides once in 12 days found to yield considerably more papaya fruits (53 /plant) and total yield (32.4 kg/plant) accounting to 100 t/ha. This treatment also recorded substantially higher water use efficiency (100.4 kg/ha.mm), saving 14.3 % water. Further, scheduling irrigation at 60 % ER and changing the irrigation sides at 12 day intervals was found to be more economical with higher gross returns (Rs. 10,00,000), net returns (Rs. 6,09,340) and benefit-cost ratio (2.60).
In vitro propagation of some important medicinal and ornamental Dendrobiums (Orchidaceae): A review
Authors: Pyati Ashok N.
Published: January 2023

Dendrobiums are highly valued in the floriculture industry and have important medicinal properties used in preparing herbal medicines in different parts of the world. Numerous anthropogenic factors are leading to the rapid loss of natural stands of germplasm. Plant tissue culture, specifically in vitro propagation, may be the only viable solution for preserving and reintroducing Rare Endangered Threatened (RET) back into the wild. An efficient protocol for in vitro seed germination and propagation through various explants of Dendrobiums was established. The protocols developed will help alleviate the pressure on the natural population under stress but also help meet its demands in pharmaceutical and ornamental industries and form the basis for conservation. A perusal of available literature reveals that micropropagation has been achieved using immature or mature seeds/embryos, protocorms, shoot tips, TLCs, leaf explants, pseudobulbs and nodal segments in Dendrobiums. This review provides a short synopsis of the advances made thus far in the in vitro propagation of ornamental and medicinal Dendrobiums.
Percutaneous Coronary Intervention in Single Coronary Ostium Presented with STEMI: A Case Report
Authors: Jefri Jefri , Wahidji Vickry
Published: January 2023

Introduction: Coronary artery anomalies presenting with ST-segment elevation myocardial infarction (STEMI) are uncommon and often are challenging to manage. We report a case of a successful percutaneous coronary intervention (PCI) of the right coronary artery (RCA) in a patient who presented with inferior STEMI and an anomaly of the left and right coronary arteries with a single coronary ostium in the right sinus of Valsalva.Case: Male, 71 years old, was admitted to the emergency department with 8 hours onset of chest pain. The patient was diagnosed with STEMI Inferior 8 hours of onset Killip I TIMI score 5. The patient was given a dual loading antiplatelet, high-dose nitrate and statin, then we planned him for primary PCI. Primary PCI was performed on the right transradial through the single osteal coronary artery from the right sinus Valsalva. We got the TIMI flow 3 without other complications during the action.Discussion: It is frequently difficult to identify the culprit lesion during primary PCI. The course of the anomalous vessel and the culprit lesion are clear often; the revascularization procedure hides several pitfalls.Conclusion: Coronary artery anomalies presenting with STEMI are uncommon but often challenging. Percutaneous coronary intervention is considered the first choice in patients with coronary anomaly presented with STEMI.
Effect of Gravity and Throughflow on Double Diffusive Convection in a Couple Stress Fluid Saturated Porous Media
Authors: Sravan Nayeka Gaikwad  , Preeti Bhushan Rangdal
Published: January 2023

We have investigated effect of throughflow and gravity modulation on double diffusive convection with couple-stress fluid saturated porous media. Applying the Landau model, we have derived finite amplitude of couple-stress convection in the presence of gravity modulation. The presence of a couple-stress parameter produces both diminishing and enhancing heat mass transfer in the layer. To present the results we have used Mathematica to obtain the Nusselt number and Sherwood numbers numerically. Further, it is shown that, throughflow and modulation of gravity controls double diffusive convection through convective amplitude and alter transport phenomenon.
Dynamic Response of Heat Transfer in Magnetohydrodynamic Blood Flow Through a Porous Bifurcated Artery with Overlapping Stenosis
Authors: Norliza Mohd Zain  , Zuhaila Ismail
Published: January 2023

The influence of heat transfers on magnetohydrodynamic blood flow treated as a Newtonian rheological model in permeable bifurcated arteries with a magnetic field applied in a transverse direction has been presented in this study. The blood flow is considered steady, incompressible, electrically conducting and porous as it consists of fatty accumulation on blood cells. A mathematical model governing such flow phenomena is developed by the Navier-Stokes and energy equations. The governing equations with appropriate boundary conditions are solved numerically by using a stabilized form of the finite element method, called the Galerkin least-squares method. The implementation of this method managed to overcome two sources of undesirable pathologies suffered by the Classical Galerkin method in solving the incompressible flow. This involves the requirement to satisfy the Babuška-Brezzi stability condition and the inherent instability arising from the approximations of highly advective flows. As a result, stable and converged solutions are generated for the velocity, temperature, pressure, wall shear stress and heat transfer coefficient in the constricted bifurcated artery by employing an equal order (quadratic triangular element) of interpolation function for velocity, pressure and temperature subspaces. The developed algorithm is validated with reported findings from previous literature where a close agreement has been achieved. Effects of the porosity parameter and Hartmann number in the presence of heat on blood flow characteristics at several locations along the branch artery are computed and presented graphically. The finding obtained from this work may be beneficial for cryosurgery and hyperthermia treatment in analysing the temperature distributions inside the vessel.

Authors: Azevedo Emanoel Mustafa de
Published: January 2023

As Reservas Extrativistas são uma categoria de Unidade de Conservação e se apresentam como importante ferramenta na conservação dos recursos ambientais, sociais e econômicos. Apesar do avanço legislativo, que culminou na criação do Sistema Nacional de Unidades de Conservação, no ano de 2000, e do novo modelo de gestão que foi adotado junto as Reservas Extrativistas no Estado do Acre, pouco se avançou na efetividade da gestão e na conservação do meio ambiente. Este estudo objetiva a análise da efetividade da gestão ambiental das Reservas Extrativistas no Estado do Acre, no período compreendido entre os anos de 1990 a 2018, com intuito de identificar se o novo modelo de gestão instituído pela Sistema Nacional de Unidades de Conservação (SNUC), tem contribuído para uma gestão efetiva, no que se refere a gestão, preservação ambiental e a economia. Constatou-se que as Reservas Extrativistas no Estado do Acre têm uma contribuição histórica e ambiental, porém pouco efetiva no que tange à gestão.

Resumo: O aumento da preocupação socioambiental com relação à exploração e ao beneficiamento de materiais rochosos, se tornam cada vez mais importantes no período contemporâneo em virtude de mitigar os impactos ambientais. Desta forma, o estudo foi realizado pela Agência Paulista em Tecnologia dos Agronegócios (APTA) - Polo Regional Alta Paulista, Adamantina (SP), utilizando amostra de resíduo coletada em julho de 2020 na forma de lama (pó de rocha oriundo do corte mais água) em beneficiadora do município de Adamantina (SP). Após secagem da lama ao sol, o material foi encaminhado ao Agrolab (Laboratório de Análises Agropecuárias) em Assis (SP) para caracterização química. O estudo objetivou caracterizar quimicamente o resíduo gerado por uma beneficiadora de rochas ornamentais, visando posterior utilização e avaliação em áreas de agricultura familiar no citado município e adjacências. Conclui-se que o resíduo apresenta elevado teor Si e não pode ser comercializado como pó de rocha; mas tem potencialidades de uso como fonte alternativa de K, Ca, Mg e S nas agriculturas familiar e agroecológica.

The Concept of Tarkib Isnadi In Arabic Grammatical Thought and Its Equivalence In Indonesian: A Contrastive Analysis
Authors: Arifianto Muhammad Lukman
Published: January 2023

This paper aims to explain the concept of Tarkib Isnadi in Arabic grammar and describe the equivalent concept and its components in Indonesian grammar. In the realm of Arabic grammar, Tarkib Isnadi is a core component in the structure of clauses or sentences in Arabic. A good understanding of Tarkib Isnadi in Arabic and its equivalent in Indonesian will make it easier for Arabic learners (L2) who come from native Indonesian speakers (L1) to identify clause and sentence structures in various Arabic discourses. The methods used in data analysis in this study are distribution and identity-referential methods. Based on observations, it is found that the concept of Tarkib Isnadi in Arabic has a concept equivalent to a clause in Indonesian because both have the core constituents or pillars of the sentence. On the other hand, there are also some differences in the concept of Tarkib Isnadi in Arabic with the concept of clauses in Indonesian. The difference mainly lies in terms of the formation of the concept and the filling components of their syntactic functions.

Abstract
This paper displays some modern linguistic approaches in teaching balaghah. Not only outlines the basic assumptions that underlie the use of these approaches in the study of balaghah, but also direct examples taken from the verses of the Qur’an. This study is considered very important to learn because will be discussed in this paper it can help Balaghah teachers in providing Balaghah materials with appropriate approaches. The approaches will help learners, so that learners gain a proper understanding of Balaghah theory and its application. This paper is the result of a literature review sourced from various national and international scientific books and articles. Data analysis is done by sorting the information and data found, classifying the data, finding relationships and examples directly from the Qur'an, verifying and concluding and analyzing. The results revealed several approaches in the teaching of Balaghah, namely the syntactic approach (Balaghah as a continuation of Nahwu), semantics (Dilalah as the main component in Balaghah), stylistics (Balaghah as Arabic stylistics), pragmatics (pay attention to communication between speaker and speaker), and semiotics. (digging the meaning of a sign through aspects of communication).

O Programa Garantia-Safra : gênese normativa e trajetória de implementação (2002-2021)
Authors: Valadares Alexandre , Alves Fábio , Silva Sandro Pereira
Published: January 2023

Propuseram a detalhar o Garantia-Safra (GS), criado em 2002 pelo governo federal para oferecer aos produtores familiares um apoio financeiro que atenuasse as perdas de safra ocasionadas pelos períodos de seca que afetam a região do semiárido brasileiro, sobretudo nos estados da região Nordeste. Os autores analisam o desempenho do GS a partir de sua trajetória em termos de estrutura normativa e cobertura programática ao longo das duas décadas de implementação (2002-2021), apontando sua importância para a agricultura familiar, mas indicando uma preocupante inflexão no seu potencial de execução, o que levaria a incertezas quanto ao seu futuro.
Migração intermunicipal no nordeste brasileiro : há evidências de seleção migratória?
Authors: Silva Filho Luís Abel da , Resende Guilherme Mendes
Published: January 2023

Investigações acerca da dinâmica migratória do fator de produção trabalho são relevantes em estudos econômicos. Na literatura nacional e internacional, há fortes evidências de que existem diferenciais de rendimentos entre migrantes e não migrantes, dadas, em sua maioria, por características não observáveis. Nesse sentido, este artigo tem o objetivo de analisar se os migrantes intermunicipais nordestinos são positivamente selecionados e se há diferenciais de rendimentos em favor deles. Recorreu-se aos dados dos Censos Demográficos do Brasil nos anos de 2000 e de 2010. O método utilizado foi um modelo proposto por Heckman (1979) em dois estágios, com correção de viés de seleção amostral. Os resultados mostram que há maior probabilidade de migração para homens e entre pessoas de raça/cor branca; aumenta a probabilidade de migração com a mudança de faixa de escolaridade; a probabilidade de migração se reduz para os casados e chefes de domicílio. No que se refere aos diferenciais de rendimentos, ser do sexo masculino, de raça/cor branca ou mudar de faixas de escolaridade conferem rendimentos superiores em relação aos seus comparativos. Em comparação aos migrantes intermunicipais do Maranhão, os migrantes intermunicipais dos demais estados da região Nordeste (com exceção do Piauí) auferem rendimentos superiores. No que se refere à decomposição, as características não observáveis e o componente de seletividade que afetam a decisão de migração também se mostram favoráveis aos diferenciais de rendimentos do trabalho, em favor dos migrantes, em ambos os anos da análise, mas o mesmo não ocorre com as características observáveis.

Authors: Santamaría-Burgos Mélsar
Published: January 2023

Con el propósito de conocer el desempeño del material de empaque para el almacenamiento y preservación del potencial germinativo de la semilla de Coffea arabica, se evaluaron cinco materiales para la semilla almacenada durante 12 meses en cuarto frío, bajo condiciones de temperatura y humedad relativa controladas: a 10,5°C y 65% de humedad relativa, en promedio. Los materiales de empaque evaluados fueron: polietileno (PE) calibre 6, papel kraft, trilaminado (PE, aluminio y papel), fique y polietileno bilaminado (PE multicapa). Se utilizó café cereza maduro procedente de la Estación Experimental Naranjal, cosechado en lotes de C. arabica de 4 años de edad, en buen estado fitosanitario y beneficiado en la Unidad de Beneficio de Semillas en Cenicafé. El café pergamino seco obtenido en el proceso de beneficio presentó valores entre 10,3% y 11,5% de humedad y porcentaje de germinación del 96%, con un error estándar de 0,94. La semilla se empacó y se dispuso de forma aleatoria al interior del cuarto frío en Cenicafé. En el laboratorio se midió el contenido de humedad y el porcentaje de germinación. Los materiales de empaque de mayor barrera al vapor de agua fueron polietileno, trilaminado y polietileno bilaminado, los cuales preservaron la calidad de la semilla durante los 12 meses, con porcentaje de germinación por encima del 94%, en promedio. Los empaques que ofrecieron menor barrera fueron papel kraft y fique, los cuales afectaron en mayor grado la germinación de la semilla, con valores entre 87% y 88%, en promedio, a partir de los seis meses. La bolsa de papel kraft, que se usa actualmente para el empaque, es un material apto para el almacenamiento de semillas de café, por períodos inferiores a seis meses.

Published: January 2023

Recientemente se ha incrementado el uso de cubiertas plásticas de color azul para realizar el secado solar del café, argumentando que sus propiedades ópticas tienen beneficios sobre la calidad en taza; sin embargo, su efecto sobre la misma es desconocido. Esta investigación determinó el efecto de cinco tipos de cubiertas plásticas diferentes, sobre la calidad sensorial y tiempos de secado realizando procesos de secado solar de manera simultánea mediante un diseño experimental de bloques completos al azar, utilizando café procedente de la Estación Experimental Naranjal. Se determinaron las curvas de secado en cada condición, así como el comportamiento de la temperatura. Al café obtenido se le realizó el análisis sensorial mediante el protocolo SCA. Se registró información acerca de las variables relacionadas con las condiciones ambientales durante cada proceso (factor de bloqueo). La calidad en taza obtuvo un promedio de 81,4 puntos SCA, el análisis de varianza no mostró diferencias significativas por efecto del uso de las diferentes cubiertas plásticas. Se presentaron diferencias en el tiempo de secado, siendo de hasta 40 horas menor para el testigo respecto a las cubiertas azul y naranja.
