Published: January 2023

The effect of annealing temperature on the structural and magnetic properties of a rare earth (La3+) doped cobalt ferrite with fine sediment from the Bengawan Solo River as the source of Fe3+ has been studied. Co-presipitation method is use for preparation nanoparticles whole this experiment. In order to modified the physical properties, the annealing treatment of 2000C, 3000C, and 4000C are performed. The obtained nanoparticles are characterized their structural properties by using X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. Then, magnetic properties evaluated by using Vibrating Sample Magnetometer (VSM). XRD results have shown that there is an increase in crystallite size with an increase in the given annealing temperature from 24.56 nm to 27.83 nm. The increase in crystallite size can be attributed to the increase in the internal energy of the crystal structure which promotes atomic diffusion. Meanwhile, there is a decrease in the value of the lattice parameter with an increase in the given annealing temperature. The decrease in lattice parameters with increasing crystallite size is generally due to the lattice parameters reaching a minimum energy with increasing crystallite size. The formation of La3+-O2- for the incorporation of rare earth ions into the lattice requires high energy. The FTIR results show an absorption that appears at the peak around ~580 cm-1. This indicates that the La3+ cation has successfully replaced the original structure of cobalt ferrite. The VSM results show that there is an increase in the value of Hc with an increase in the annealing temperature given from 100 Oe to 160 Oe. This is supported by the increase of anisotropy constant and increasing temperature annealing.
Effects of Hydrolysis Ratio on the Structure and Adsorption Properties of Porous Starch
Authors: Jiang Xiao Dong , Wang Jian Kun
Published: January 2023

This study was carried out to investigate the effects of hydrolysis ratio on the structure and adsorption properties of porous starch. The starches with different hydrolysis ratios were prepared by enzymolysis (combination of α-amylase and glucoamylase), and its adsorption capacity was evaluated by using methylene blue (MB) and soybean oil as adsorption objects. The results suggest that crystallinity, specific surface area and adsorption capacity of porous starch were gradually improved with the increase of hydrolysis degree. The crystallinity of native starch was increased by enzymolysis from 28.43±0.23% to 34.70±0.69%, and the specific surface area was increased from 0.58±0.002 m2/g to 1.82±0.014 m2/g. Moreover, the adsorption capacity toward (MB) was increased from 2.88 mg/g to 3.87 mg/g at 25°C, which was accurately described by the pseudo-first-order kinetic model, and the oil absorption ratio was also greatly improved from 23.2±0.16% to 76.1±0.11%. Thus, the properties of porous starch can be adjusted by controlling the hydrolysis ratio to meet different needs in the market.

Published: January 2023

This work aims to reveal the effect of the stand of distance (SOD)during the abrasive water jet cutting processes of Material implant stainless steel 316L on its corrosion properties. Abrasive water jet cutting processes were conducted in 5 different SOD there are 1, 2, 3, 4, and 5 mm between the nose of the nozzle and substrate surface. After these processes, the cross-section of the substrate was evaluated on its corrosion character using the potentiodynamic polarization method under Cl based solution. This process was conducted at room temperature with an almost steady state condition scan using Ag/AgCl/KCl as the reference Electrode and Pt as the counter electrode. The Results show that the corrosion resistance decreased as the SOD increased.

Authors: Sagaya A. , Abdulrahaman A. A.
Published: January 2023

Duranta erecta L. is one of the most important plants used in landscaping with many medicinal properties though not studied well. Several reports have been previously published on the variations in this species leading to various taxa names. The methanol extracts were analysed by GC-MS in order to identify specific compounds unique to the different forms that exists. Eighty-nine compounds were scored for the eight forms, carboxylic acids and alcohol occupied the most abundant compounds and ketone, aldehyde, alkane, alkene, alkyne, nitrile, ester, amide, epoxide and heterocyclic compounds were also detected.  All the eight forms revealed similarity percentage value lower than 50% and the highest value for the compounds was observed between variegated yellow and variegated yellow double (VY X VYD 32.14%) and the lowest between variegated white and thorny green (VW X TG 14.08%). The Cluster Analysis (CA) revealed that all the variegated forms cluster together while the broad green, yellow bush and green bush form another cluster. The thorny green remains in isolation from other forms and standing as the major cluster two. On PC1 highest score was correlated with TG form while others had values with negative scores. In component 2 (PC2), highest score is correlated with YV, VW, VYD and VY which are morphologically similar while others had negative scores. GC-MS was successfully employed in this study to classify the forms therein proposing as hybrids using the multivariate analysis.

Comparative study between clinical diagnosis, plain radiography and sonography for the diagnosis of nontraumatic acute abdomen
Authors: Sharma Pradeep , Sood Rajan , Sharma Mukul , Gupta Arun K. , Chauhan Arun
Published: January 2023

ABSTRACT

Background:

Acute abdomen is the most commonly attended surgical emergency. It can be caused by intra-abdominal, extra-abdominal and metabolic causes. A few imaging modalities are at disposal of primary care physicians like plain x-ray and ultrasonography.

Materials and Methods:

This study has been done to compare the efficacy of clinical diagnosis, plain radiography and sonography in diagnosis of non-traumatic acute abdomen. Every patient under study admitted in the Department of General Surgery underwent thorough clinical evaluation, biochemical investigations, X-rays and sonography. Findings of clinical evaluation, X-Rays and sonography were compared to the final diagnosis found intraoperatively.

Results:

Clinical diagnosis was made in 47 (94%) out of 50 patients. X-rays were able to diagnose in 20 patients (40%) whereas sonography diagnosed 26 patients (52%).

Conclusion:

The present study showed that clinical evaluation, x-rays or Ultrasound alone are not sufficient to diagnose cause of non-traumatic acute abdomen in all cases. Clinical evaluation combined with x-rays and ultrasound increases the number and accuracy of pre-operative diagnosis in non-traumatic acute abdomen.
Multifocal posterior fossa pilocytic astrocytoma in a child: Case report and review of literature
Authors: Gala Foram B , Agarwal Harshal , Chawla Pawan , Andar Uday
Published: January 2023

Abstract

Pilocytic astrocytoma (PA) is the most common posterior fossa tumor in children; however, multifocal posterior fossa PA is very rare in children and is usually associated with risk factors such as neurofibromatosis. We described a rare case of multifocal posterior fossa PA involving pons, bilateral cerebellar hemispheres, vermis, and middle cerebellar peduncle in a child in the absence of any associated risk factor. The lesion also showed extensive areas of calcification which is also uncommon in PA.
Finite transitive groups having many suborbits of cardinality at most 2 and an application to the enumeration of Cayley graphs
Authors: Spiga Pablo
Published: January 2023

Let G be a finite transitive group on a set
$\Omega $
, let
$\alpha \in \Omega $
, and let
$G_{\alpha }$
be the stabilizer of the point
$\alpha $
in G. In this paper, we are interested in the proportion
$$ \begin{align*} \frac{|\{\omega\in \Omega\mid \omega \textrm{ lies in a }G_{\alpha}\textrm{-orbit of cardinality at most 2}\}|}{|\Omega|}, \end{align*} $$

that is, the proportion of elements of
$\Omega $
lying in a suborbit of cardinality at most 2. We show that, if this proportion is greater than
$5/6$
, then each element of
$\Omega $
lies in a suborbit of cardinality at most 2, and hence G is classified by a result of Bergman and Lenstra. We also classify the permutation groups attaining the bound
$5/6$
.

We use these results to answer a question concerning the enumeration of Cayley graphs. Given a transitive group G containing a regular subgroup R, we determine an upper bound on the number of Cayley graphs on R containing G in their automorphism groups.
Mean square values of L-functions over subgroups for nonprimitive characters, Dedekind sums and bounds on relative class numbers
Authors: Louboutin Stéphane R. , Munsch Marc
Published: January 2023

An explicit formula for the mean value of
$\vert L(1,\chi )\vert ^2$
is known, where
$\chi $
runs over all odd primitive Dirichlet characters of prime conductors p. Bounds on the relative class number of the cyclotomic field
${\mathbb Q}(\zeta _p)$
follow. Lately, the authors obtained that the mean value of
$\vert L(1,\chi )\vert ^2$
is asymptotic to
$\pi ^2/6$
, where
$\chi $
runs over all odd primitive Dirichlet characters of prime conductors
$p\equiv 1\ \ \pmod {2d}$
which are trivial on a subgroup H of odd order d of the multiplicative group
$({\mathbb Z}/p{\mathbb Z})^*$
, provided that
$d\ll \frac {\log p}{\log \log p}$
. Bounds on the relative class number of the subfield of degree
$\frac {p-1}{2d}$
of the cyclotomic field
${\mathbb Q}(\zeta _p)$
follow. Here, for a given integer
$d_0>1$
, we consider the same questions for the nonprimitive odd Dirichlet characters
$\chi '$
modulo
$d_0p$
induced by the odd primitive characters
$\chi $
modulo p. We obtain new estimates for Dedekind sums and deduce that the mean value of
$\vert L(1,\chi ')\vert ^2$
is asymptotic to
$\frac {\pi ^2}{6}\prod _{q\mid d_0}\left (1-\frac {1}{q^2}\right )$
, where
$\chi $
runs over all odd primitive Dirichlet characters of prime conductors p which are trivial on a subgroup H of odd order
$d\ll \frac {\log p}{\log \log p}$
. As a consequence, we improve the previous bounds on the relative class number of the subfield of degree
$\frac {p-1}{2d}$
of the cyclotomic field
${\mathbb Q}(\zeta _p)$
. Moreover, we give a method to obtain explicit formulas and use Mersenne primes to show that our restriction on d is essentially sharp.
Case Report: Amphotericin B and Mefloquine as a Salvage Treatment of Alveolar Echinococcosis
Authors: Jelicic Karlo , Papic Neven , Viskovic Klaudija , Vince Adriana
Published: January 2023

Alveolar echinococcosis is an emerging zoonotic disease caused by the parasite Echinococcus multilocularis. Most patients are diagnosed at a late stage, when lifelong treatment with benzimidazoles is required to stop disease progression. However, for patients who do not tolerate benzimidazole therapy, there are no alternatives. Here, we present a patient with advanced alveolar echinococcosis who was successfully treated with amphotericin B deoxycholate and mefloquine as a rescue therapy after he developed albendazole intolerance.
The main peculiarities of labour migrants’ integration in Georgia (case of Tbilisi and Batumi)
Authors: Gogsadze Giorgi , Dolbaia Tamar , Sitchinava Tatiana
Published: January 2023

Following the dissolution of the Soviet Union, Georgia became a country of intensive emigration. However, the last decade has marked a notable change in the country’s migration profile due to the inflow of immigrants. This is a new challenge for contemporary Georgia, especially in terms of immigrant integration. The purpose of this paper is to identify the main features of labour migrants’ integration into Georgian society. The research findings are mostly based on the results of a qualitative sociological research, employing in-depth interviews with migrant workers residing in Georgia, and experts of the field. Lack of complete legislation and sound policies is the main characteristic feature of labour immigration management in Georgia; therefore, the migrant integration process goes spontaneously: one group of migrants, namely English- and Russian-speakers, as well as skilled workers still feel comfortable, and they keep intense communication with the local population. Another part of migrants who is denied state support in studying Georgian remains isolated from the host society.
The Ethical Values and Leadership Practices in Deuteronomy
Authors: Emina Kemi Anthony
Published: January 2023

A search for a philosophy of leadership has to begin with ontological and epistemological questions. The former deals with what leadership is and the latter is concerned with how one can know. Hence, this work engages in exploring the meaning, scope, and nature of leadership through the methods of analysing common words and metaphors of leadership in the Old Testament, particularly the Book of Deuteronomy. In addition, the research perspectives on the nature of leadership in the area of leadership studies are discussed to arrive at a more comprehensive understanding of the characteristics and functions of leadership. This article deals with the ethical values that lay the foundation for the leadership practices in Deuteronomy. In doing so, sources of moral courage will be discussed first, as people’s personal and corporate moral courage has to originate from certain concepts, which serve as a philosophical underpinning, driving leaders in the ethical directions of leadership practices. Next, leadership with a concern for people and ethics is discussed. The crux of the philosophy of Deuteronomy is that people should choose life by obeying the law of the Lord and avoid destruction that results from disobeying the law. Hence, leadership practices are there to create life or well-being for the people. Finally, there will be a study on how ethical practices shape society, with reference to Israelite society in the context of the narratives in the Book of Deuteronomy.
The Pastor’s Role in Effectively Managing the Congregation’s Potential: A Case Study in GKII Gracia Sintang
Authors: Herwinesastra Herwinesastra , Luther Henry , Rostiani Rostiani
Published: January 2023

This article examines the pastor's role as a religious leader in empowering the congregation's potential. Research for this article was conducted in GKII Gracia parish, Sintang. Qualitative method was utilized by the researchers, who interviewed the pastor, church committee members, and many members of the congregation. Data triangulation was used to obtain pertinent information from interview transcripts, and the results were then presented in a descriptive manner. Based on the collected data, these roles—which the pastor does in his capacity as a spiritual leader—were recognized as being essential to achieving church autonomy in GKII Gracia Sintang: 1) enlistment of the congregation in spiritual ministry to involve them according to their own abilities and potential, 2) optimization of external opportunities and utilization of internal potential to achieve good results, 3) mobilization of the congregation through encouraging and galvanizing them to participate in church ministry. In order to support these roles, particularly mobilization, training, pastoral visitation, and sermon delivery aimed at awakening the congregation to the importance of their participation were carried out.

A Study on Dental Caries and Remedial Measures Needed Among the School Children Aged Between 6-12 Years in Selected Schools of Tumkur Town, to Develop Information Guide Sheet on Prevention of Dental Caries
Authors: L Clement L , A Michael Jeba Arasi
Published: January 2023

Dental Caries can affect attendance, scholastic performance (lack of attention due to pain) and nutritional status. Children suffering from toothache or dental problems avoid or change their regular eating patterns. In neglected oral hygiene along with dental caries, periodontal diseases are seen. Periodontitis from the upper jaw may transmit the infection to the brain. Fluoride plays an important role in the prevention of dental caries, but it also causes fluorosis in excess amounts. Fluorosis aggravates dental carries. It is imperative to diagnose these problems at their early stage to prevent complications & to restore them in case it’s a permanent teeth. Objectives of the study • Assess the existing knowledge of school children regarding dental caries. • To examine by visualization of the oral cavity for the presence of dental caries. • To associate the presence of dental caries with demographic data of children. • To determine the remedial/treatment needs. • To prepare the information booklet on preventive measures and remedial measures as well. Methods: The research design of the study was a descriptive cross-sectional study. The population was school children of age 6-12 years. The study originated with a sample of 150 children from selected schools in Tumkur. The sample of an equal proportion of children was scientifically drawn at random by using a random number table from each age group. Results: The present study shows that the mean knowledge among school children was 44.1%. This study revealed that schoolchildren were having very less knowledge regarding dental caries. Knowledge of prevention was 39.5%. This shows that school children were having very less knowledge regarding the prevention of dental caries. The prevalence of dental caries was 61.3% and this is the proportion referred for treatment needs among school children. The study found a significant association between knowledge of dental caries with the age of the children (χ2 =24.64, df=2), the mother’s education (χ2 =19.87, df=1) father’s education (χ2 =4.62, df=1), Mother’s occupation (χ2 =8.06, df=1), father’s occupation (χ2 =6.04, df=1) and several children (χ2 =17.72, df=1) are resulted as significant at 5% level. The proportion of treatment needs identified among the school children was 83.7% for teeth restoration, 13.0% for tooth extraction, and 3.3% for special treatments. Conclusion: The above findings depict that school children were having an inadequate level of knowledge on the prevention of dental caries. Based on the findings, an information guide sheet was developed to create awareness among school children.

Authors: Kulkarni Roopa R , Sharma Abhishek D , Koundinya Bhuvan K , Anirudh Chokkanahalli , N Yashas
Published: January 2023

India faces a serious threat from several insect pests and diseases in the area of grape cultivation. Grape cultivation throughout India is currently facing several major threats, including fungal pests and diseases such as downy mildew, powdery mildew, anthracnose, and mealybug. This disruption to the grape industry inevitably leads to economic losses for both farmers and the countrywide economy. By using appropriate pesticides at the right time and in dosages, farmers can minimize these negative effects while still preserving crops even in the presence of harmful chemicals. Additionally, neglecting grape leaf diseases can lead to significant damage to plants. Powdery mildew and downy mildew are two prime examples of plant diseases that can take a heavy toll on crop yields. Integrated technology into viticulture and horticulture is critical for improving grape production and preventing future economic turmoil. A disease of the grape leaves like downy mildew, or powdery mildew can cause great losses to the farmers. In the leaves, fruits, and on stems of plants, we can identify diseases. Detecting the diseases of the leaves in their early stages is a challenging task and is a must for higher yield. Current researches trends are on the chemical composition of pesticides, in turn, are harmful to human health.
Colonialismo, comunidad y capital. Pensar el despojo, pensar América Latina
Authors: Martínez Navarrete Edgars
Published: January 2023

Este libro reúne una serie de textos que analizan las intersecciones entre las herencias coloniales, las múltiples formas de despojo capitalista y las respuestas que han dado distintas experiencias comunitario-populares en América Latina. Creemos que la profundización del capitalismo neoliberal que en estos momentos se deja caer sobre las tensiones irresueltas de la dialéctica Estado y sociedad en nuestra América, está signada por la persistencia histórica de diversas modalidades de colonialismo que siguen operando. Ante ello, parte de los sujetos afectados por las consecuencias de la expoliación capitalista y su lógica colonial han reaccionado con fuerza, y a partir de sus propias tradiciones de organización, están trastocando el sentido convencional de la participación política en América Latina. Ante la necesidad de comprender nuestra América, cada uno de los textos de este libro busca contribuir con claves analíticas que permitan ir más allá del binomio conceptual de despojo y resistencia para entender la complejidad de sus imbricaciones, tensiones y formas de resolución. Con ello queremos contribuir a la academia y a los movimientos comunitarios y populares con los que trabajamos y somos parte, con ideas y planteamientos que puedan ser útiles para analizar algunas de las intersecciones subyacentes entre la comunidad, el colonialismo y al capital. Con ello queremos aportar a entender su despliegue a escala continental sin perder de vista la especificidad de las formas y respuestas que se han articulado desde diversas experiencias políticas en las últimas tres décadas.
Mujeres autónomas y autodeterminación de los andes bolivianos: una apuesta ante el colonialismo interno
Authors: Arteaga Böhrt Ana Cecilia
Published: January 2023

En un contexto marcado por los cambios de orden político y legal, y a su vez, por el poder centralizado del aparato burocrático del Estado Plurinacional boliviano, analizo el devenir de las autonomías en Bolivia, enfocándome principalmente en los proyectos de autodeterminación en los Andes. Reflexiono particularmente en torno al proyecto de Totora Marka (departamento de Oruro), desde la mirada de las mujeres aymaras, visibilizando sus esfuerzos por hacer reconocer su voz en las instancias de decisión colectiva y traducir sus sentidos y demandas de género. Me interesa desarrollar las formas de organización creadas, renovadas y reforzadas ante las lógicas del despojo capitalista, colonial y patriarcal que se desarrollan en torno al Estado-nación. En este marco, me enfoco en el concepto de colonialismo interno para explicar la trilogía entre comunidad, colonialismo y capital desde los proyectos de autodeterminación.

Las comunidades indígenas y campesinas de América Latina enfrentan una ofensiva extractivista signada por el despliegue de múltiples procesos de despojo y violencia sobre aquellos territorios y medios de existencia que garantizan su sustento y hacen posible la reproducción de la vida humana y no humana. En este texto, esbozo un breve recuento de la emergencia contemporánea del movimiento indígena en México en la década de los noventa y el tiempo más reciente en el que se articulan y agrupan centenas de luchas en defensa de la vida. Así, analizo desde la clave de la producción de lo común, las dinámicas de las tramas comunitarias que se organizan para enfrentar los asedios y afectaciones del extractivismo en sus territorios.
Comunidad, desposesión y recreación étnica en México y Guatemala
Authors: Bastos Amigo Santiago
Published: January 2023

Este capítulo propone considerar la comunidad indígena no como una permanencia precolonial, sino como una construcción histórica en que es fundamental la vivencia por siglos dentro de una situación de subordinación étnica, por lo que se trata de una entidad compleja y contradictoria, cambiante y diversa. En la actualidad la comunidad indígena en México y Guatemala está en proceso de transformación en el contexto neoliberal. Uno de los factores de cambio es el papel desarrollado por las instituciones y lógicas comunitarias en las luchas contra las actividades extractivistas que se desarrollan en sus territorios. Al insertarse esta defensa dentro de las luchas por los derechos de los pueblos indígenas, la comunidad indígena es vista como anticolonial y anticapitalista convirtiéndose en un horizonte de lucha poderoso que transforma a las mismas estructuras comunitarias.
Reproducir los comunes: estrategias Maya-Q’eqchi’s contra la expansión de monocultivos en el Valle del Polochic, Guatemala
Authors: Mingorría Sara
Published: January 2023

En este capítulo se analiza cómo y porqué se crean y reproducen los comunes temporales y duraderos, como parte de los entramados comunitarios de los Maya-Q’eqchi’ en el Valle del Polochic, Guatemala. Se muestra como la reproducción de los comunes Maya-Q’eqchi’, ha sido y es la base de la resistencia ante la nueva oleada de despojo por la expansión de los monocultivos de caña de azúcar y palma aceitera propiedad de familias oligarcas descendientes de alemanes. Se analiza el común como una forma de lucha característica de los Maya-Q’eqchi’, desde sus múltiples diferencias de funcionamiento y estructura entre territorios habitados por Maya-Q’eqchi’ y también desde sus diferencias dentro del mismo territorio. Finalmente, se discute sobre los factores que han condicionado esas diferencias y cómo son reconfigurados por la historia y las dinámicas socioeconómicas y ambientales; así como por la estructura y funcionamiento que adquiere el propio común.

El objetivo general del presente estudio fue determinar la incidencia de la gestión administrativa escolar en la satisfacción de los padres de familia del nivel primaria de un colegio público de Huaral en el 2022, para esto se consideró realizar una investigación de tipo aplicada, con un enfoque cuantitativo, con diseño no experimental y un alcance correlacional causal. Se estudió como población a los padres de familia, estudiando una muestra de 114 padres, determinado a partir del muestreo aleatorio simple. A ellos se les aplicó 2 cuestionarios validados y confiables. Entre sus principales resultados se encontró que el 47% de los padres de familia consideró que la gestión administrativa se presenta en nivel alto; el 51% indicó que esta variable se presenta en nivel medio y un 2% en nivel bajo; así también, que el 63% de los padres de familia, mostraron un nivel de satisfacción alto, un 36% mostraron un nivel medio de satisfacción y un 1% un nivel bajo. Tras aplicar la prueba de correlación de Spearman se encontró que las dimensiones de la gestión administrativa se relacionan de forma significativa con la satisfacción de los padres de familia, así mismo se aplicó la prueba de d de Somers y se obtuvo que existió una dependencia de la satisfacción con respecto a la gestión administrativa percibida. Se concluyó que la gestión administrativa escolar incide sobre la satisfacción de los padres de familia en la institución en estudio, es decir que a medida que la gestión administrativa mejore, la satisfacción verá reflejada esta mejora en su comportamiento.
PERSPECTIVAS DA BNCC SOBRE ALFABETIZAÇÃO E LETRAMENTO PARA A PRÁTICA DE PROFESSORES ALFABETIZADORES NAS SÉRIES INICIAIS
Authors: MELO DA SILVA ALDENIZE , DE JESUS PINHEIRO FERREIRA BENEDITO
Published: January 2023

O presente trabalho discute sobre a alfabetização e o letramento que está dentro do componente curricular língua portuguesa na Base Nacional Comum Curricular (BNCC) nas séries iniciais, sobretudo nos 1º e 2º anos do ensino fundamental. Essa pesquisa visa abordar sobre como se dá o processo de alfabetização e letramento existente na Base e as perspectivas desse processo para a prática de professores alfabetizadores. Tendo como objetivo principal verificar como a alfabetização e o letramento aparecem dentro do documento da BNCC. Este artigo é resultado de uma pesquisa de cunho curricular, e para o desdobramento do referido artigo, dadas as temáticas para a investigação, usou-se a pesquisa bibliográfica, buscando dialogar com nomeados autores como Soares (1999; 2003; 2020), Mortatti (2006), Fiorin (2011), Freire (1990; 1996), entre outros autores visando abordar sobre o contexto da alfabetização e letramento e fundamentar a pesquisa. Assim, também foi utilizada a técnica de análise documental, ao qual se utilizou a BNCC como fonte para extrair os dados almejados e desenvolver a pesquisa. Com base nos estudos realizados conclui-se que, a BNCC relaciona a alfabetização com o sistema de “codificar e decodificar” os fonemas e grafemas, na aquisição da leitura e da escrita contribuindo para que o aluno tenha o domínio da “mecânica” da língua oral e escrita. O letramento por sua vez na BNCC está relacionado ao contato da criança com as variadas práticas de leituras nos diversos contextos sociais e que na escola, primordialmente nas séries iniciais (1º e 2º anos), essas práticas serão consolidadas e ampliadas.

Introduction: Three doses of SARS-CoV-2 mRNA vaccines have been recommended for cancer patients to reduce the risk of severe disease. Anti-neoplastic treatment, such as chemotherapy, may affect long-term vaccine immunogenicity.
Method: Patients with solid or haematological cancer were recruited from 2 hospitals between July 2021 and March 2022. Humoral response was evaluated using GenScript cPASS surrogate virus neutralisation assays. Clinical outcomes were obtained from medical records and national mandatory-reporting databases.
Results: A total of 273 patients were recruited, with 40 having haematological malignancies and the rest solid tumours. Among the participants, 204 (74.7%) were receiving active cancer therapy, including 98 (35.9%) undergoing systemic chemotherapy and the rest targeted therapy or immunotherapy. All patients were seronegative at baseline. Seroconversion rates after receiving 1, 2 and 3 doses of SARS-CoV-2 mRNA vaccination were 35.2%, 79.4% and 92.4%, respectively. After 3 doses, patients on active treatment for haematological malignancies had lower antibodies (57.3%±46.2) when compared to patients on immunotherapy (94.1%±9.56, P<0.05) and chemotherapy (92.8%±18.1, P<0.05). SARS-CoV-2 infection was reported in 77 (28.2%) patients, of which 18 were severe. No patient receiving a third dose within 90 days of the second dose experienced severe infection.
Conclusion: This study demonstrates the benefit of early administration of the third dose among cancer patients.

Neste trabalho, resultado de seu estágio pós-doutoral na Universidade Federal da Paraíba (UFPB), Manassés Morais Xavier, docente da Universidade Federal de Campina Grande (UFCG), dois centros de excelência em pesquisa linguística, desenha uma investigação primorosa que parte de seu repertório teórico – especialmente em Bakhtin e Martín-Barbero; passa pela exposição de uma metodologia que se debruça sobre as interações (postagens e comentários) reais de pessoas que se manifestam em redes sociais como o Instagram, entre outras, inclusive apresentando esses ambientes ao leitor e à leitora; constrói uma análise coerente e relevante sobre o que ali ocorre, em especial por meio de situações escolhidas, isto é, o pesquisador seleciona cinco “acontecimentos enunciativos” específicos, que “dão o que falar”, como dizemos popularmente, a fim de observar e analisar as interações ali, quais sejam: (1) a publicação do samba-enredo da Mangueira, escola de samba carioca, (2) uma notícia sobre o ex-presidente da república, (3) uma notícia sobre um ex-ministro da educação do governo anterior, (4) um caso de assassinato de criança que mobilizou o país e (5) uma notícia sobre a Covid-19. O coração do trabalho de Manassés Xavier é justamente essa análise, que põe em evidência as interações que ali ocorrem, dando ensejo a conclusões importantes sobre discurso e sociedade. Segundo o autor deste livro intitulado As redes sociais digitais como acontecimentos enunciativos de interações discursivas, obra que se soma ao rol das mais relevantes no tema, “lemos as redes sociais como o convite ao exercício dialógico de responder a enunciados concretos por natureza”. Além disso, elas se revelam como “terreno propício para a não indiferença à palavra enquanto signo, e signo ideológico”, já que as pessoas em interação nesses espaços explicitam, segundo o investigador, uma “perspectiva de uso da palavra orientada para a interação discursiva, podendo perceber e construir pontos de vista, valorações”, tal como é possível flagrar e confirmar nos dados organizados e sistematicamente aqui apresentados.

The goal of this study was to evaluate the effect of corporate governance on the performance of SACCOs, in Rukiga District. SACCO governance was a predictor variable and performance of SACCOs was the study’s outcome variables. A cross-sectional survey was the precursor to the study. Quantitative and qualitative analysis were combined with the collection and analysis of data from 109 respondents. Descriptive, bivariate, and multivariate analyses were used in the analysis, which was done on three different levels. Frequency tables were employed to portray the data as descriptive analysis required presentation of a single variable and its characteristics. A Pearson correlation matrix was used to determine the correlations between the predictor factors and the dependent variable at the bivariate level. The modified predictor variables for corporate governance were regressed against the dependent variable at the multivariate level (performance of SACCOs). To fit the data, a linear regression model was employed. Corporate governance (coef. = 0. 532) has a positive influence on the performance of SACCO in Rukiga District, according to research results from the regression model. The key finding of this study is that corporate governance significantly affects SACCOS performance. The study therefore suggests that in order to ensure the sustainability of SACCO performance in Rubanda District, greater emphasis should be placed on implementing corporate governance.
Basic Principles Inspire the Relationship between the Leaders and the Followers in the Physical Revolution in Bali

The basic principles of leadership in Bali have been known since the royal era and even earlier, namely since the community has settled down, gathered, defended the environment, since then the leadership element has entered. Leadership in Balinese society is inseparable from Balinese local wisdom, which is a form of unification of culture, customs, and religion. During the royal period until the physical revolution in Bali, leadership was always based on the philosophy of Hinduism. A leader in his leadership should always be based on the teachings of Asta Brata. In the 1945 physical revolution in Bali, leadership on the part of the fighters was greatly influenced by circumstances and nationalism. To be able to understand the loyalty of the people in war cannot be separated from the basic principles that underlie the link between leaders and followers which originate from the teachings of Hindu religious philosophy, especially teachings that discuss the basis of leadership which is always oriented to the nature/gods as a manifestation of God. To support the status of a leader, it is usually manifested in the form of an heirloom keris, the use of titles, troops and so on. Familiarity, the sense of responsibility of the leader with the loyalty that is led melts together. The leader will inflame the spirit of struggle, his followers are always loyal to support him. So that a strong patron-client relationship is established. From this background, this paper reveals the basic principles that underlie the link between leaders and followers in the physical revolution in Bali. The main problem: What are the basic principles that underlie the link between leaders and followers before and during the physical revolution in Bali? Data collection used the historical method through several stages, namely heuristics, source criticism, interpretation, and the stage of writing research results. The limited written data sources that were collected to complete this work used the method of direct interviews with the combatants who held the helm at that time. And supported by a patron-client approach. The results of the study show that the basic principles that underlie the link between leaders and those who are led before and during the physical revolution in Bali are strongly influenced by situations and conditions, the spirit of leadership which originates from the teachings of Hinduism. The link between the leader and the fed is an absolute requirement for the emergence of leadership because there are people who want to follow those who lead.

This study examines a discrete-time enzyme model with Caputo fractional order. We look into the existence and uniqueness of fixed points in the discrete dynamic model and discover parametric criteria for their local asymptotic stability. Additionally, it is demonstrated using bifurcation theory that the system experiences Period-Doubling and Neimark-Sacker bifurcation in a constrained area around the singular positive fixed point and that an invariant circle would result. It has been determined that the parameter values and the initial conditions have a significant impact on the dynamical behavior of the fractional order enzyme model. Additionally, with the use of Matlab tools, numerical analysis is offered to illustrate the theoretical debates. Therefore, numerical simulations are used to support the key theoretical findings.

Tea plants are one of the exports commodities in Indonesia. In their development, the plantation ecosystem is heavily influenced by several factors, both internal and external factors. In the field of applied mathematics, mathematical modelling can be used to analyze the development of tea plant growth and their interactions each other in their ecosystem. The mathematical model in this research is combining three main models, there are logistic model, epidemiological model, and predator prey model by adding fungicide and insecticide controls. Furthermore, local and global stability analysis is carried out and the optimal control problem is solved by Pontryagin maximum principle. The results of the analysis obtained five equilibrium points. Local stability analysis was carried out using the Routh Hurwitz criteria which showed the fifth equilibrium point is locally asymptotically stable. The basic reproduction number in the model is 0.99. Because 16R0<1" style="width: 28pt; height: 11pt;">, it can be concluded that there is no spread of disease in the tea plantation ecosystem after a period of 5 years. The control provided can reduce pest and disease attacks. After being given control, the population of infected tea plants decreased by 93.21%, Empoasca pests decreased by 99.47%, and leaf roller caterpillars decreased by 99.31% compared to the model that was not given control.

The lived experience of using educational technology is embedded in a specific social and cultural context. This study aims to investigate the meaning of the lived experience of the pesantren community using technology for education in their learning environment. This study used the hermeneutic phenomenology method to interpret the meaning of the experience of the pesantren community. Eight people from a pesantren for college students were purposively selected as participants. They were asked to describe their experiences using technology for education, how they used it, and what it meant for them. Thematic analysis of the interview transcripts was then carried out to obtain interpretations of the meaning of the participant experiences. The analysis results reveal the meaning surrounding maintaining the pesantren subculture, the disruptive impact of technology, and the struggle for inclusion and social mobility. This study concludes that technology can be used to adapt the culture of pesantren education. The contribution of this research strengthens the theoretical implications of the linkages between educational technology and culture by providing empirical evidence from the experience of the pesantren community as a subculture.

Klidar's novel by Mahmoud Dolatabadi is one of the culmination of contemporary prose in Iran, and Uncle Tom’s cabin's novel by Harriet Beechrasto is one of the most distinguished American novels. In the present article, some similarities and differences in content and structure, as well as the fictional characters of these two authors have been investigated. The main similarity between the two authors is that each of them has spoken emotionally about the political and social issues of their time, and historical events direct the narrative movements of these two novels, which are a socio-political expression of a fact. And these two novels from different aspects, including: Influenced by the prevailing conditions of society, intellectual and literary similarities and writing styles, descriptions, characterizations have been criticized and both dramatic moments have been portrayed in a prominent way.
