Nonlinear buckling and postbuckling analysis of cylindrical and sinusoid FG-GPLRC panels under axial compressive load
Authors: Dao Quang Huy  , Nguyen Thi Phuong
Published: October 2023

This paper presents and analyzes the nonlinear buckling responses of cylindrical and sinusoid Functionally graded graphene platelet reinforced composite (FG-GPLRC) panels under axial compressive load. The higher-order shear deformation theory is applied to establish the governing equations of structures. The stress function is approximated using the like-Galerkin method, and the Galerkin method is applied to solve the governing equations. The critical buckling loads and postbuckling load-deflection curves are expressed in explicit form. The effects of panel types, geometrical parameters, imperfection, and foundation on the critical buckling loads and postbuckling curves of cylindrical and sinusoid FG-GPLRC panels are discussed. Numerical results also evaluate and compare the buckling responses of cylindrical and sinusoid panels.

Authors: Iqmaludin Iqmaludin
Published: October 2023

CT scan images with metal artefacts may reduce the image quality and diagnosis of CT scan images. Metal Artefact Reduction (MAR) can effectively reduce artifacts caused by metal implants. ASIR-V plays a role in reducing noise and improving image quality. To prove the reduction of metal image artefacts and optimization of CT scan image quality after the application of MAR and ASIR-V (30,60,90) of Head and Neck CT Scan by finding the value of SNR, CNR, anatomical information and the level of metal artefact interference after metal artefact reduction. Quasi-type experimental research design with pre-post test only without control group design. The study sample was 15 CT scan images of head and neck with purposive sampling. SNR and CNR measurements were quantitatively analyzed using the Wilk test, followed by the Wilcoxon test. Anatomical information assessment was performed qualitatively by two radiologists and analyzed by kappa test. Anatomical information and the level of metal artefact interference with CT scan images were carried out by the Friedman test, followed by the Wilcoxon test. There is a difference in SNR Pvalue (p=0.000<0.05), CNR Pvalue (p=0.000>0.05), anatomical information Pvalue (p=0.000<0.05), level of metal artefacts Pvalue (p=0.000<0.05) after using MAR and ASIR V. The use of MAR and ASIR-V methods can reduce metal artefacts in images that contain artefacts with the use of MAR + ASIR-V 90% the most optimal.

O interesse na utilização de águas residuárias tem crescido, devido a limitação de água de boa qualidade, em destaque para o semiárido. Este trabalho teve por objetivo analisar as alterações químicas do solo irrigado com águas residuárias e da adubação fosfatada, na produção de muda de Moringa oleifera Lam. O experimento foi instalado em estufa, do viveiro florestal da Estação Experimental Prof. Ignácio Salcedo do Instituto Nacional do Semiárido – INSA, Campina Grande – Paraíba. Adotou-se o delineamento de blocos casualizados, arranjo fatorial 5 x 2, com quatro repetições, com cinco percentuais de água residual doméstica tratada, diluída em água de abastecimento (25%; 50%; 75%; 100% e água de abastecimento tratada), associados a dois fatores nutricionais (AF – adubação fosfatada e SA – sem adubação). Aos 110 dias após condução dos tratamentos, avaliaram-se as seguintes características do solo: potencial hidrogeniônico, condutividade elétrica, cálcio, magnésio, sódio, fósforo, potássio, soma de bases, alumínio, hidrogênio, sulfato, capacidade de troca catiônica e matéria orgânica. O uso da adubação fosfatada contribuiu de maneira positiva nos teores de fósforo, carbono, matéria orgânica e capacidade de troca catiônica do solo. Os percentis crescente de água residuária alavancaram a soma de bases e a capacidade de troca catiônica, simultaneamente promoveu o aumento nos teores de Na+, Al, H+Al e na condutividade elétrica do extrato de saturação do solo.

Published: October 2023

Os grandes polos de produção bovina no Brasil realizam a condução da produção, por meio do pastoreio intensivo das pastagens, promovendo algum grau de degradação. Os sistemas agroflorestais são considerados alternativa viável para a recuperação de áreas degradadas, decorrentes da produção de gado, no entanto, a falta de conhecimento sobre os benefícios relacionados a esta estratégia de cultivo pode dificultar a adoção destes sistemas. Assim, objetivou-se entrevistar quatro setores da sociedade de São Félix do Xingu-PA para compreender e constatar a aceitação, contribuição, conhecimento e anseios para a implantação de sistema silvipastoril na região. Para esta pesquisa, aplicaram-se questionários em diferentes setores da sociedade local, setor acadêmico de nível superior, setor de comércio representado pelos empresários locais, setor da zona rural representado pelos agricultores e setor da zona urbana representado por membros da comunidade em geral. Sobre o sistema silvipastoril, o comércio apresentou maior porcentagem de desconhecimento (84,00%). Em relação aos benefícios do sistema, constatou-se que há um desconhecimento maior dos munícipes situados na zona urbana (88,89%). Ao questionar sobre ações realizadas com os sistemas silvipastoris, constatou-se que os munícipes da zona urbana (96,30%) nunca participaram das mesmas. Quanto à indicação do sistema, constatou que os setores do comércio (100,00%), zona rural (82,61%) e acadêmico (100,00%) são favoráveis à sua implantação. Sobre os benefícios ambientais, a zona urbana (85,19%) apresentou desconhecimento. E ao falar dos maiores retornos econômicos advindos do sistema, os entrevistados pertencentes ao comércio (84,00%) desconhecem esses retornos. Conclui-se que a maioria dos munícipes desconhecem o sistema, com isso, sugere-se que mais ações voltadas ao tema sejam realizadas, possibilitando levar essas informações à população, para que o sistema seja mais difundido e implantado pelos agricultores da região.
Breakeven price of CO2 credits driving farmers to use the area to plant forest instead of grain
Authors: Palumbo Marco , Ferraz-Almeida Risely
Published: October 2023

Afforestation and reforestation were the challenges the farmer can seize to plant a culture that can capture more carbon than the amount emitted for cultivation. Assuming that the land was legally rented and owned, and part of an area that had not been obtained through recent deforestation, the main questions were: “why a farmer should have preferred to reserve the area to plant trees?”; and “How much did one ton of Carbon Dioxide [CO2] have to be rewarded to buy this opportunity?” This work had the target to estimate which was the minimum price for carbon credit so that the farmer will plant a forest instead of using the soil for grain cultivation. Based on the analysis that economic aspects and profit were the main drivers considered by the farmer to decide how to use the soil in case the area was not classified as Legal Reserve or Permanent Protection Area, seeking the usage which maximized the value per hectare. Considering a eucalyptus commercial forest planted under the premises of the current study, results showed that a price of around 24 BRL per ton of CO2 in 2021 is enough to turn it economically feasible. Business case had been estimated with and without profit coming from the commercial use of forest, and even assuming that no wood is cut and sold, the 2021 price of 40,48 BRL per ton of CO2 can ensure more profit than grain production over 14 years timeframe, allowing the farmer to make money beyond the usual commercial use of a forest.
Interfaces do processo de construir-se professor: uma revisão integrativa da literatura sobre a professoralidade na saúde
Authors: Mattia Bianca Joana , Paz Arruda Teo Carla Rosane
Published: October 2023

A Constituição Federal brasileira positivou a saúde como direito, instituiu o Sistema Único de Saúde e o definiu como ordenador da formação profissional na área. Porém, a legislação não trata da docência na área da saúde. Assim, é importante entender como um profissional da saúde torna-se professor, buscando-se captar a essência desse fenômeno no conceito de professoralidade. O objetivo desse trabalho foi compreender a construção da professoralidade na área da saúde, por meio de uma Revisão Integrativa de Literatura. A busca pelos estudos foi realizada na Biblioteca Virtual em Saúde e no Portal de Periódicos CAPES, aplicando-se, aos selecionados, Análise de Conteúdo Temática. Este texto se ocupa da categoria “interfaces do processo de construir-se professor na área da saúde”, originada da análise de 32 artigos incluídos na revisão. Observou-se que a construção da professoralidade na saúde é campo permeado por tensões, influências e saberes. As principais tensões foram: reconhecimento da docência como processo que requer aporte teórico-metodológico; premência de perceber a docência como profissão e a formação docente como formação profissional; sobrecarga de trabalho docente; (pseudo)equivalência entre produção científica e qualificação docente; sensibilização docente para comprometer-se com a formação permanente. Entre as influências, destaca-se: formação disciplinar inicial; formação continuada; exemplos de antigos professores. Constatou-se que, além dos saberes disciplinares específicos, a docência na saúde requer saberes pedagógicos, políticos, históricos e filosóficos. Conclui-se que é imprescindível compreender os elementos que constituem a professoralidade nesta área, com vistas a uma práxis voltada ao fortalecimento do SUS.

Authors: Câmara Márcio Paz , Canan Silvia Regina
Published: October 2023

O presente artigo objetiva tratar sobre a gestão escolar democrática, analisando sua normatização, seu histórico e definição; também abordará a gestão e o processo participativo, a democracia e o direito social. A Lei n. 7.040/98/SEDUC/MT terá destaque, visando identificar os pontos fortes e as fragilidades desta Política Pública do Estado do Mato Grosso. Trata-se de parte de um estudo descritivo com abordagem qualitativa, resultante de pesquisa desenvolvida no Mestrado em Educação. Percebe-se que mesmo existindo uma legislação específica, a gestão escolar democrática no Estado em destaque ainda não se efetiva completamente, em muitas unidades escolares. Por outro lado, há de se destacar também a identificação de boas práticas aplicadas nas escolas. Os resultados encontrados também sinalizam a necessidade de uma maior periodicidade na formação continuada, para que haja estreitamento de laços entre a escola e os membros da comunidade escolar, visando a aplicação da Lei n. 7.040/98/SEDUC/MT e seus dispositivos legais.

Published: October 2023

O trabalho teve por objetivo compreender a política de atendimento à Educação Infantil do Município de São Paulo no período de 2005 a 2018. Trata-se de uma pesquisa de abordagem quanti-qualitativa, de natureza teórica e de tipo documental e bibliográfico. A coleta de dados foi feita por meio de pesquisa: i. em fontes primárias, com foco na legislação educacional, no orçamento municipal e nos dados de matrículas e escolas, compreendendo as três distintas redes; ii. em fontes bibliográficas acadêmicas sobre infância, direito à educação infantil, financiamento e privatização. O referencial teórico tem como base autores que desenvolveram estudos nas áreas de direito à educação, financiamento e privatização. O caminho analítico percorreu a trajetória histórica do conceito de infância, criança e de seu atendimento educacional, a positivação jurídica dos direitos das crianças, a política de financiamento dessa etapa educacional e as estratégias de atendimento e gestão propostas, em especial as que se orientam na direção da privatização dessa etapa de ensino. A análise dos dados permitiu identificar um aprofundamento da política de privatização na oferta de vagas para a Educação Infantil no Município de São Paulo, por meio da flexibilização desse atendimento.
O uso da sequência didática no ensino de geografia para a formação dos sujeitos do campo
Authors: Souza Tatiane Rodrigues de , Clemente Evandro César
Published: October 2023

O objetivo deste texto foi debater e apresentar proposição de Sequência Didática (SD) para o ensino de Geografia visando contribuir com o debate da proposta da Educação do Campo a partir dos conteúdos do Currículo Oficial do Estado de Goiás do Ensino Médio. A SD apresentada é voltada para as práticas educativas que buscam valorizar a diversidade e as singularidades dos alunos das escolas situadas nas áreas rurais. Os procedimentos metodológicos utilizados baseiam-se em pesquisa bibliográfica e documental, elaboração e aplicação da SD em uma instituição de ensino do município de Jataí-GO. Observou-se que a SD baseada nos conteúdos geográficos se constitui em uma metodologia que poderá fornecer aos alunos as bases necessárias para a formação e a compreensão da sua realidade. Todavia, acredita-se que todas as práticas pedagógicas ao longo da formação dos estudantes necessitam ser constantemente fortalecidas por debates que possam reconhecê-los como sujeitos sociais que devem se posicionar como classe e reivindicar seus direitos, como por exemplo, a educação do campo.
Wybrane metody estymacji w semiparametrycznym modelu granicznym
Authors: Prędki Artur
Published: October 2023

In the paper estimation methods of the production function which are used in the special frontier model are described. The frontier model is of a semiparametric nature, as the production frontier is not given analytically. However, assumptions related to the model errors have parametric character. In order to estimate the frontier, the so-called StoNED (Stochastic Non-smooth Envelopment of Data) multi-stage procedure is used. The first step forms the CNLS method (Convex Nonparametric Least Squares), which is a nonparametric counterpart of OLS. Next stages run according to a scheme, which has been used on the ground of the stochastic frontier models for many years. As a result not only the estimator of the production function is received, but also the estimator of the inefficiency term for a given production unit. In the paper some critical remarks are presented. They are related to faults and limitations of the research methodology. Next, the procedure is illustrated with an empirical study. Finally, potential directions for further research in the area are presented.

Authors: Lipieta Agnieszka
Published: October 2023

Assume that, in a private ownership Debreu economy Ep, among all the commodities there are at least two whose quantities, employed by consumers in all their plans of action, are proportional. This property leads producers change their production plans to satisfy the consumers’ requirements. The producers’ adjustment process, caused by the special form of consumers’ plans, is modeled. As the result, the economy ˇEp with dynamical production and consumption systems is defined. The commodity – price space of economy ˇEp is the space of continuous functions defined on time interval [0; 1] with values in the commodity – price space of economy Ep.

Published: October 2023

The article is devoted to problem of detection of overt or tacit collusion equilibrium in the context of choice of the appropriate econometric method, which is determined by the amount of information that the observer possesses. As a particular method to be used we have chosen a collusion marker coherent with an equilibrium of the proper model of strategic interaction – the presence of structural disturbances in the price process variance for phases of collusion and competition. We than used a proper econometric tool, namely Markov Switching Model with switching in variance regimes in order to verify its functionality in a context of a research. We applied the model to cement industry of India in a period of 1994–2009. We have reached some promising effects in discovery of collusion and competition phases, partially confirmed by facts from functionality of the industry and by reference research.

Authors: Żółtaszek Agata
Published: October 2023

Health care is a key sector of every economy and is of grate medical, social, and economical importance to all citizens. It is also one of the most diverse sectors in the world, especially in the aspect of financing. In Poland health care is mostly public funded. However due to system’s inefficiency new policies are discussed, some of which include various methods of co-payment. Popularisation of currently uncommon private medical insurance, either supplementary or complementary to public financing, are one of the proposed solutions. The main goal of this paper is to present health econometric micro simulation model of households’ medical expenses in Poland. Model is based on individual household panel data considering private funding of health care and willingness-to-pay for private medical insurance. It is to be used to forecast future situation depending on various funding reform proposals. This research is to prove usefulness of micro simulations in assessing health care police, which is of currently of major importance in Poland.
Mierzenie ryzyka stóp procentowych: przypadek rynku międzybankowego w Polsce
Authors: Olsza Paweł
Published: October 2023

The article presents an example of the application of different approaches to the measurement of interest rate risk. Empirical analysis described in the article was carried out using data from the Polish interbank market for the period from September 5th, 2000 to November 19th, 2010. Interest rate risk measurement techniques using principal component analysis (PCA) are presented in the article. These techniques, by giving appropriate economic interpretation of each principal component, can also be used in the sensitivity analysis of the portfolio of debt securities to specific interest rate curve movements. The article also discusses the issue of the appropriate selection of scope and range of market data used in the analysis and its possible impact on values and stability of eigenvectors obtained using PCA. Three different hedging strategies were tested in order to check the effectiveness of interest rate risk measurement using PCA, the first based on PCA, the other based on the measures of effective duration, effective convexity, and BPV, the last considered strategy assumed no hedging at all. The results showed no significant differences in the degree of portfolio value protection in case of hedging strategy using PCA and the one based on the measures of effective duration, effective convexity, and BPV.
Application of Structural Equation Modeling for analysing internal migration phenomena in Poland
Authors: Pietrzak Michał , Żurek Mirosława , Matusik Stanisław , Wilk Justyna
Published: October 2023

Migrations form the size and structure of human resources in regions. For that reason they have not only a demographic but also a social and economic character. The existing research is often not enough due to a spatial, temporary and also a multidimensional character of this occurrence. The subject of this paper is to apply Structural Equation Modeling (SEM) concept for analysing the population migration phenomena considering the gravity model. This approach allows describing the social and economic situation in regions considering a set of correlated variables and it also allows determining its influence on migration flows. The first part of the article describes the construction and interpretation of the gravity model and the concept of the SEM model. In the second part the adopted research procedure and the research scope are presented. In the last part, the results of the investigation are explained. The strength and direction of the impact of the socio-economic development on the migration flows between subregions (NUTS 3) in Poland in the years 2008-2010 are discussed.
Wykorzystanie modelu SVECM do badania zależności pomiędzy cenami surowców a cenami stali na rynku europejskim w latach 2003-2011
Authors: Papież Monika , Śmiech Sławomir
Published: October 2023

The article presents the analysis of the relations between the demand for steel products and the prices of steel and raw materials (coking coal) on the European market based on the monthly data in the period 2003-2011. The analysis of those relations was conducted with the use of Structural Vector Error Correction Model (SVECM), which allowed to determine the impact of the supply of raw materials and the demand for steel products on the prices of steel products. The results obtained indicate that steel market is in long run equilibrium. The price of coking coal is the dominant variable in the system, and the prices of crude steel depend on the prices of raw materials and the demand for steel products. The price of steel is not the Granger cause for the remaining variables. As expected, the system reacts both to the increase in the demand for steel products and the increase in the prices of raw materials. The forecasts obtained using the model are valid enough and can be treated as reference points by the participants of the steel market.

El trabajo por inscribirnos en la historia: memorias de una joven militante estudiantil en la dictadura uruguaya
Authors: Achugar Mariana
Published: October 2023

Los vacíos de la memoria con respecto a experiencia de jóvenes bajo el terrorismo de Estado son formas de impunidad que afectan a toda la sociedad e impiden comprender lo que hizo posible estos niveles de violencia. En el caso de las memorias sociales sobre la última dictadura en Uruguay las narrativas dominantes son protagonizadas por adultos y son construidas por adultos dando prioridad a los testimonios de varones. Este tono monocorde de la memoria hegemónica deja afuera gran parte de la experiencia que ayudaría a explorar otras posibles narrativas más allá de imaginarios de guerra. La incorporación de nuevos sujetos en las construcciones de la memoria social de la dictadura en Uruguay como las mujeres, lxs jóvenes responde a un nuevo contexto de escucha y a formas de organización que permiten intentar dar nuevos sentidos al pasado transformando recuerdos privados en memorias colectivas. En este trabajo se explora el caso de una joven militante estudiantil que introduce nuevos actores, acontecimientos y circunstancias que permiten desarticular discursos que sostienen la impunidad.
Comenzar a militar con alegría. Las acciones en el espacio público de lxs hijxs de represaliadxs en Córdoba y La Plata
Authors: Puttini María Paula , Pighin Daniela
Published: October 2023

Entre las diversas acciones que el Movimiento de Derechos Humanos desplegó en nuestro país durante la década de 1980, en algunas ciudades se desarrollaron talleres integrales que respondieron a las demandas de las infancias represaliadas. Sostenidos e impulsados desde la Federación Latinoamericana de Asociaciones de Familiares de Detenidos-Desaparecidos (FEDEFAM), los talleres se constituyeron en espacios donde transitar la experiencia de ser “hijx de represaliadx”. El objetivo del presente artículo radica en analizar los casos de dos de estos talleres: el “Taller Julio Cortázar” -Córdoba- y el “Taller de la Amistad” -La Plata-, atendiendo al lugar que ocuparon lxs jóvenes en dichos espacios. Específicamente, nos interesa estudiar la capacidad de agencia de las infancias y adolescencias represaliadas durante el terror de Estado. En torno a ello, nos preguntamos ¿qué acciones pudieron gestionar lxs jóvenes de manera autónoma? y si ¿estas acciones podrían entenderse como un paso a la acción colectiva en el espacio público? Para responder ambos interrogantes, en el caso de Córdoba, nos centraremos en diversas acciones llevadas a cabo por el grupo de adolescentes del “Taller Julio Cortázar” que implicaron tomar el espacio público o interactuar con pares. En el caso de La Plata, analizaremos acciones y posiciones asumidas por lxs adolescentes que dan cuenta de su autonomía dentro de este espacio.
APCs and Uneven Distribution

The things that concern me about article processing charges (APCs) for open access are not those surrounding quality control, “predatory publishers” or so forth. Given that we want the services of publishers, their labour costs must be met. If we want to have open access and then the material can’t be sold, an author-side payment mechanism looks the most obvious.

Mechanisms of protection of national and entity interests in Bosnia and Herzegovina's parliamentarism
Authors: Šukalo Marko
Published: October 2023

In the paper, the author analyzes the mechanisms for the protection of vital national and entity interests at the BiH level, in entities and cantons in the Federation of BiH, emphasizing the importance of these mechanisms as an essential element of Bosnian parliamentarism and the constitutional system as a whole. The normative analysis and the comparative method revealed differences in the procedures for the protection of vital national interests in the entities, on the one hand, and on the BiH level, on the other. The author presents the imperfections of these institutes, suggesting possible solutions, but at the same time emphasizing their essential value in the complex and segmented BiH. At the very end, the author concludes that the mechanism of protection of vital national interests in the BiH Parliament is relative, for which the Constitutional Court of BiH is responsible, and points out the importance of entity voting mechanisms, which expediently protects the rights of entities and constituent peoples.
The cooperation between libraries and museums with the review on the cooperation between the Public library "Bora Stanković", Vranje and the National museum of Vranje
Authors: Bundalo Sanja
Published: October 2023

The study is dealing with the cooperation between the libraries and museums. Essentially, every cultural institution's interest in different ways of cooperation comes naturally regarding the preservation and promotion of the cultural heritage. Until recently, there haven't been many initiatives towards promoting mutual cooperation. The matter requires a wider debate and closer attention because it affects almost all cultural institutions. However, there are some libraries and museums whose cooperation has been productive and successful. This study will present the examples of good practice which demonstrate that such cooperation as one between the public library "Bora Stanković" and the National Museum of the city of Vranje can last for decades as an object worth of praise and pride for each of the institutions. This cooperation has been gradually intensifying for years suggesting that the synergy between the two authentic local institutions can be an example to the whole cultural establishment.

This work presents the characteristics of children's magazines, the origin and development of children's periodicals in Serbia and the importance of children's magazines. In France, in 1757, the first children's literary magazine, Dečji magazin is created. During the 19th and 20th centuries, the following magazines were published in Serbian language: Školski list, Dečji prijatelj, Radovan, Golub, Neven and many others, whose existence significantly influenced the development of young readers who, in addition to poems and stories, could find a theatrical pieces, translations, riddles, rebuses, crossword puzzles and more. Editors, publishers and associates who were more prominent Serbs of that time, made a significant contribution to the development of the periodicals of that time. During the 20th century, the topic of the magazine changed, so the main topics were war, criticism of capitalism and building a new society. In the twenty-first century, the magazine also moved to online media. An example is certainly electronic literary magazine for children and youth - Slova na struju from the Public Library "Radislav Nikčević" in Jagodina. By reading magazines, children develop creativity and imagination, form a view of the world, develop beautiful feelings, and spend quality free time. There are also magazines that use their concept to affirm the creativity of students and thus encourage them to become creators of various contents.

Reading is a complex skill that primarily depends on the components of the reader's language knowledge that applies to understand the meaning of what he has read. Considering the modern man's need for knowledge of at least one foreign language, the paper refers to the types of reading that are used to achieve success at different levels of knowledge (intensive and extensive reading) and the application of certain strategies in order to understand the text. About 6,500 titles from various fields are available to the users of the Užice library's collection of books in foreign languages, which are most represented in English, Russian, German and French, and in a smaller number in over fifty other languages. Bilingual and multilingual publications are especially important for learning, when one of the languages is Serbian. The selection of a book, which should be aligned with the level of knowledge of the language in which it is read, librarian can make it easier with an adequate recommendation and reference to the effective searches of the fund in the Kobis+NBU database, which are presented in the paper.
The role of shelterbelt for soil management in Ethiopia
Authors: Asmare Melkamu
Published: October 2023

Soil is a vital component for the growth of trees and shrubs in the shelterbelts agroforestry practices. Management of trees has a critical contribution to soil improvements. People's use of shelterbelts is varying across agroecology zones of Ethiopia. Some nations use it as their cultural expression, while the others use it as area demarcation (farming and home). In shelterbelt agroforestry practice, Millettia ferruginea, Sesbania sesban and Acacia abyssinica legumes tree species were deliberately planted for soil management across agro-ecologies. Considering the population and the farm size of farmers in Ethiopia, most farmers' knowledge of shelterbelts for soil management is scantly documented. This is due to a low level of awareness and expert consultancy. Therefore, this paper reviews the soil management roles and possible threats, opportunities, and challenges of shelterbelts. This review paper was developed through using related published papers. Scientists reported that areas covered by well-managed shelterbelts had good soil physical, biological, and chemical properties. The soil quality and fertility of the area further improved through good soil microbial activities. The tree crop compatibility, climatic factors, land use policy, and scarcity of land were among the possible threat and challenges to shelterbelts establishment. Generally, good tree and shrub management skills result in a high level of land productivity. Therefore, further development planners should focus on the extensive demonstration of shelterbelt practices as well as training and monitoring of farmers on such issues for their livelihood improvements.
Evaluation of end tidal capnography and upper airway ultrasonography for confirmation of endotracheal tube placement in adult patients undergoing elective surgery: Capnography versus ultrasonography for endotracheal tube placement
Authors: Srikanth N. , Banerjee Neerja , Gupta Neha
Published: October 2023

Introduction: Capnography has been considered the gold standard method for confirmation of endotracheal tube placement. The current cross-sectional observational study was undertaken to compare upper airway ultrasonography and capnography for confirmation of endotracheal tube placement in patients undergoing elective surgery. Methods: 75 adult patients (18-60 years of age) belonging to ASA physical status I or II, scheduled for elective surgery under general anaesthesia requiring oral endotracheal intubation were enrolled for the study. After intubation, proper placement of endotracheal tube was confirmed by chest auscultation, end tidal capnography and upper airway ultrasonography simultaneously. Sensitivity, specificity, positive and negative predictive values of both capnography and ultrasonography were computed. Results: Using capnography, the position of endotracheal tube was found to be in the trachea in 72 patients (96%) and not in the trachea in 3 patients (4%). Ultrasonography was able to detect all 3 esophageal intubations but failed to confirm 2 endotracheal intubations. Capnography had sensitivity, specificity, positive and negative predictive values all at 100%. Ultrasonography had sensitivity of 97.22%, specificity of 100%, positive predictive value of 100% and negative predictive value of 60%. The kappa value was 0.737 which indicates a good correlation between capnography and upper airway ultrasound. Conclusion: Ultrasonography provides a real time dynamic visualization of the endotracheal tube. This study was able to demonstrate that ultrasonography is an acceptable, faster and safer method for confirming endotracheal tube placement. However, further studies are recommended to determine the best approach for emergency situations, patients with a difficult airway, and in critical care settings.

Abstract

Lymphoma is the most common lymphoid malignancy in hematology, including Hodgkin’s lymphoma and non - Hodgkin’s lymphoma. In particular, non - Hodgkin’s lymphoma is the majority (80 - 85%), classified into B - cell non - Hodgkin’s lymphomas, T cell non - Hodgkin’s lymphomas and NK/T cell non - Hodgkin’s lymphomas. Treatment of non - Hodgkin’s lymphoma includes surgery, radiotherapy and chemotherapy. Chemotherapy has been considered a standard treatment, but there are still some limitations. Nowadays, with the invention and development of the targeted therapy, it has opened a promising future for non - Hodgkin’s lymphoma patients. This therapy prevents the growth of cancer cells by directly interfering with specific molecules, thereby inhibiting reproduction and tumor growth. Currently, the targeted therapies used in non - Hodgkin’s lymphoma include monoclonal antibodies such as Anti - CD20 (Rituximab, Obinutuzumab),... antibody - drug conjugates such as Anti - CD30 (Brentuximab),... small molecular inhibitors such as Bruton Tyrosine Kinase Inhibitors (Ibrutinib), Proteasome Inhibitors (Bortezomib),... and CAR-T cell. In addition, some other targets are still being researched and put into use, thereby bringing many opportunities for non - Hodgkin’s lymphoma patients. The targeted therapy has proven outstanding effectiveness and played an irreplaceable role in the treatment of non - Hodgkin’s lymphoma.
