Published: October 2021

Purpose: The study aimed at finding out whether parents play a role in the teaching learning process of pupils in public schools in public primary schools in Laikipia West sub-county.

Methodology: A mixed method research design was used where   cross sectional descriptive survey was used on quantitative data and phenomenology was used to complement components of qualitative data. Population of 13 public Primary schools was sampled from the total 65 public Primary Schools in the Sub-County. Out of 2,236, pupils’ in class 6, 7 and 8, 3 girls and 3 boys were selected per class through stratification and simple random method.  Parents/ guardians for the selected pupils were purposively selected regardless of their age, level of education and gender.  All class teachers from the sampled schools were targeted and purposively selected. The data was collected using questionnaires, interview guide, document analysis guide and focus discussion guide. Statistical Package for Social Sciences (SPSS) version 17 was used to analyze quantitative data.

Results: The results from the study showed that there is prevalence of parental roles on the pupil’s learning process in Laikipia West Sub- County mainly through attending school functions, assisting with homework, communicating with teachers and their children and provision of learning resources.

Unique Contribution to Theory, Practice and Policy: The recommendation was that those parents who were not actively involved on pupil’s academic related matters be sensitized on their roles of promoting child education.  The County as well as national governments should support parents by establishing structures and policies that boost the standard of education in the area. According to this study such policies includes; establishing efficient and effective guidance and counseling programs in school, taking legal action on parents who keep their children at home, providing full sponsorship to needy parents and establishing boarding schools among the pastoralists communities.

Published: October 2021

Introdução: A candidíase vaginal recorrente é uma infecção que ocorre de forma frequente na vida da mulher. O trato genital feminino é acometido por fungos, sendo o principal a Candida albicans, que gera um desequilíbrio da flora vaginal por alterações fisiológicas ou não. Objetivos: Estudar os fatores que influenciam no surgimento da candidíase e quais os meios de prevenção devem ser reforçados para que a mesma não venha a surgir. Material e métodos: Foram utilizados como materiais e método para atingir os propósitos da presente pesquisa o estudo de revisão bibliográfica relacionado a candidíase, através da análise de artigos científicos encontrados na plataforma Scielo datados de 2010 a 2020 tanto em língua portuguesa quanto em inglesa publicados em revistas médicas. As palavras chaves utilizadas para a pesquisa foram "candídiase recorrente", "candidíase vaginal" e "recurrent candidiasis". Foram selecionados os artigos mais relevantes à proposta do artigo e que melhor se adequaram a atingir os objetivos descritos para a pesquisa. Resultados: Foi observado que a candidíase vaginal é recorrente quando ocorre no mínimo quatro casos de infecção ao ano. Os fatores que a desencadeiam ocorrem predominantemente àquelas mulheres que tem hábitos considerados de risco, como o uso de roupas com tecido sintéticos, justas na região perineal, bem como as portadora de diabetes, disfunções hormonais e as que sofrem estresse diariamente. Ainda, constatou-se o fato de que a mudança alimentar para uma nutrição saudável contribue para a cura e prevenção da candidíase. Conclusão: Os estudos mostram que o fungo que mais causa candidíase é o Candida albicans, ainda que existam outros. O tratamento indicado tradicionalmente é o uso de pomada vaginal e medicamento oral, além disso, algumas mudanças de hábitos alimentares podem ser preventivas. Uma das formas de diminuir os fatores seria evita-los e agregar uma alimentação saudável na vida cotidiana da mulher, aliado a distribuição de informações acerca do assunto quanto a profilaxia dessa infeccção que hostiliza tão frequentemente as mulheres.

Authors: Silva Caio Henrique Silva da , Trindade Bianca Caroline Gouvêa , Rodrigues Alzeir Machado
Published: October 2021

Introdução: A hanseníase (conhecida antigamente como lepra) é uma doença infectocontagiosa provocada pela bactéria Mycobacterium leprae, transmitida pelo contato direto com secreções respiratórias de um indivíduo infectado, assim como pelo contato com animais infectados, como os tatus. Atualmente, o Brasil é o segundo país com mais casos novos da enfermidade no mundo. É uma doença crônica, marcada pelo surgimento de lesões cutâneas associadas à alteração da sensibilidade no local, que pode levar a sequelas físicas incapacitantes e a deformidades em casos de tratamento tardio, configurando-se como um problema de saúde pública e de intervenção imprescindível. Objetivo: Caracterizar o perfil epidemiológico dos casos novos de hanseníase na população brasileira no ano de 2020. Material e métodos: Trata-se de um estudo ecológico, do tipo quantitativo e descritivo. Utilizaram-se dados obtidos a partir do Departamento de Informática do Sistema Único de Saúde (DATASUS), referentes às notificações de hanseníase no Brasil no ano de 2020. Avaliaram-se os dados de acordo com a unidade federativa, raça, sexo, faixa etária e escolaridade. Resultado: Em 2020 houve um total de 19.478 novos casos de hanseníase no Brasil. Os estados em que mais houveram notificações foram: Mato Grosso (2.795), Maranhão (2.308) e Pará (1.949). Analisando-se as regiões brasileiras, o Nordeste apresentou 8.190 casos, seguido do Centro-Oeste com 4.366 e Norte com 3.876 casos. Quanto à faixa-etária da população afetada, a maior parte (11.067) possui entre 40 e 69 anos, enquanto que no quesito raça, observou-se que houve um predomínio de casos em pessoas pardas (11.698). A prevalência de casos novos foi superior no sexo masculino (11.404) em comparação pessoas do sexo feminino (8.074). Acerca da escolaridade, verificou-se que a maior parte da população afetada (7.221) possui Ensino Fundamental incompleto. Conclusão: Diante do exposto, constatou-se que a população mais afetada compreende, sobretudo, homens, nordestinos, autodeclarados pardos, com idade entre 40 e 69 anos e que possuem o ensino fundamental incompleto. Percebe-se, desse modo, a necessidade de maior atenção ao perfil epidemiológico da população brasileira em relação à hanseníase, para que favoreça a redução das infecções por esta causa, bem como incentivar o diagnóstico precoce e promover maior adesão ao tratamento.

SEPSE DECORRENTE DE BACTÉRIAS MULTIRRESISTENTES EM UNIDADES DE TERAPIA INTENSIVA BRASILEIRAS: UMA REVISÃO INTEGRATIVA
Authors: Costa Ronald Pinto , Matos Gabriel Cheles Nascimento , Souza Gabriel Ângelo Araújo De , Santos Alcione De Oliveira Dos
Published: October 2021

Introdução: A sepse é conceituada como uma resposta inflamatória exacerbada do hospedeiro a doenças infecciosas. No Brasil, é considerada a segunda maior causa de mortalidade em Unidades de Terapia Intensiva (UTIs), além de gerar perdas econômicas aos hospitais, referentes ao prolongado período das internações. Pode ser causada por bactérias, vírus, fungos ou protozoários, sendo as bactérias os principais agentes etiológicos. Estas, quando caracterizadas como multirresistentes, resistem à ação de antimicrobianos disponíveis, por meio, por exemplo, de síntese enzimática e alterações na permeabilidade celular, dificultando o tratamento de doenças anteriormente tratáveis. As manifestações incluem variados estágios clínicos, como a síndrome da resposta inflamatória sistêmica, a sepse grave e o choque séptico. Objetivos: Assim, busca-se analisar o acometimento de sepse por bactérias multirresistentes em pacientes internados em UTIs brasileiras. Material e métodos: Para isso, utilizou-se pesquisa bibliográfica, através de ferramentas on-line de busca por artigos científicos em inglês e português, como Google Scholar, PubMed e Scielo, entre os anos de 2012 e 2020. Resultados: Dessa forma, constatou-se que organismos multirresistentes, como as bactérias gram-negativas Pseudomonas aeruginosa e Acinetobacter baumannii, predominam nas UTIs brasileiras. Contudo, o agente infeccioso mais incidente é a bactéria Staphylococus epiderdimis, que gera infecções relacionadas ao uso de cateteres e pode ser transmitida pela equipe de saúde, por localizar-se na pele de pessoas saudáveis. Sendo assim, há riscos aos indivíduos submetidos a procedimentos invasivos, com doenças crônicas ou pacientes hospitalizados por longos períodos. Além disso, o uso indiscriminado de antimicrobianos torna o ambiente suscetível ao aparecimento de microrganismos multirresistentes. Há casos em que a ineficiência de antimicrobianos dificulta o tratamento, podendo evoluir para óbito em 35-45% para casos de sepse grave e 52-65% para o choque séptico, principalmente na região Centro-Oeste do país. Conclusão: Por fim, infere-se que desafios relacionados à propagação de bactérias potencialmente causadoras de infecções em pacientes de UTI são comuns mundialmente. No Brasil, apesar da expressiva incidência de casos de resistência bacteriana, ainda há carência de pesquisas, a fim de efetivar ações sanitárias direcionadas para reduzir a gravidade de casos e índices de pacientes afetados anualmente.

Penelitian ini menyatakan bahwa sebuah karya buku dapat menjadi penggerak untuk kebangkitan umat Islam dari keterpurukan dan keterbelakangan. Buku merupakan sebagai medium untuk penyebaran ide, gagasan dan cita-cita serta menjadi kekuatan dalam sebuah arus pembangunan peradaban.  Namun pergolakan di Syuriah belakangan ini seperti menghapus apa yang ingin dicapai dalam buku tersebut yaitu kebangkitan umat. Manifesto merupakan catatan-catatan untuk menempuh tujuan utama kebangkitan umat. Buku ini paling tidak menawarkan sebuah gagasan walaupun realitas di Syuriah tidak terbentuk kebangkitan umat. Kajian terhadap karya ini dianalisis dengan menggunakan teori Gill Branston dan Roy Stafford dalam buku the Media Student’s Book (2003:11-15) yang menyebutkan bahwa (1) kata-kata atau tanda-tanda semiotika selalu memulai dari sebuah struktur nilai yang telah terbentuk dari masyarakat, (2) sebuah teks media selalu mengandung struktur, (3) sebuah teks mengandung makna denotasi dan konotasi. Pemaknaan secara semiotika, struktural, denotasi/konotasi terhadap karya buku karya Said Nursi ini menggambarkan pesan dibangun berdasarkan teks atau simbol yang sudah terstruktur dalam masyarakat Islam. Kedua, karya ini dibentuk oleh struktur yang terbangun saat penulisan buku. Ketiga, karya ini secara denotatif dapat dimaknai sebagai manifesto kebangkitan Islam secara keseluruhan. Namun secara konotatif karya ini menunjukkan keinginan untuk kebangkitan Islam di Syuriah namun gagal

Isolation of protease inhibitor producing bacteria from microbial mat and investigating its anti-biofilm potential against biofilm producing organism was selected as the main objective of the present study. Protease inhibitor (PI) was produced from bacterial isolates and purified using ammonium sulphate precipitation methods. Primary and secondary protease inhibitor assay was carried out separately to confirm the inhibition of protease enzyme activity both qualitatively and quantitatively. Antibacterial activity and anti-biofilm assay was performed to determine the biofilm prevention capabilities of PI. Three isolates (B1PI, B2PI and B3PI) were screened and B2PI bacterial culture was selected based on the results of primary and secondary protease inhibitor assay. Maximum trypsin inhibition of 77.5±0.25% was recorded for the isolate B2PI. Antibacterial activity of the B2PI protease inhibitor fractions exhibited inhibitory zones of 22.3±1.04mm and 20.2±0.25mm against Escherichia coli and Staphylococcus aureus respectively. Anti-biofilm assay of protease inhibitor fractions expressed 31.2μl/ml of MBIC against Escherichia coli and Staphylococcus aureus. The results conclude that, the protease inhibitor from the microbial mat isolate will be an effective alternative to the commercial antibiotics either alone or in combination with other drugs synergistically which shall be studied elaborately in future.

Authors: Nguyen Ngoc Tue  , Nguyen Duc Trung
Published: October 2021

It can be seen that the objects of wastewater that need to be treated are quite diverse in types and complex in terms of reaction mechanisms. The methods mainly focus on the treatment of toxic organic compounds, especially phenols or plant protection agents in industrial wastewater, paper industry, food production, textile industry, printing industry... The activation of H2O2 and O2 by complexes of transitional metal ions and suitable ligands creates oxidizing agents and ecologically healthy products. The intermediate substances arising in the activation process such as free radicals OH., O2., HO2., ... can oxidize many compounds, especially the ability to attack the aroma of organic pollutants. In this paper, the results of research on treating organic pollution in restaurant wastewater with H2O2 are presented as a catalyst of complexes between Mn2+ ions and EDTA. The conditions including pH, EDTA/Mn2+, the concentration of H2O2, Mn2+ were investigated to obtain the optimum conditions for improving COD treatment efficiency. This work proposes a method based on formation of the Mn(II)-EDTA complex,  b=1; with the optimal conditions of other factors as following [H2O2]0 = 0,75.10-3 mol/L; [Mn(EDTA)]2- = 33,33 mol/L, pH=10.5; t = 15 minutes. The initial COD of 1025 mg/L decreased to 135 mg/L after the proposed procedure.  The results provide solutions of homogeneous complex catalysts for domestic/restaurant and industrial wastewater treatment at room temperature and atmosphere.

Fifteen year-old teak wood samples planted in Ciamis FMU (Perhutani Enterprise) were evaluated for their chemical properties. Three seed sources such as conventional seed, clone, and superior wood and radial positions namely sapwood, outer heartwood, and inner heartwood were the observed factors. The specimens were taken from the bottom parts of their sources. Completely randomized design was used. Cell wall components were analyzed by various gravimetric methods.Analysis of variance and Duncan’s test were performed for data analysis. The results showed that no significant difference in the quantity of cell wall components (cellulose, hemicellulose, and lignin), extractives (ethanol-toluene and hot-water solubles), ash, and silica content among the seed sources. Superior teakwood or Jati Plus Perhutani, which has the highest growth rate (2.1~3.6 cm/year) among others, showed a comparative higher average pH values (7.08~7.38) and solubility in 1% NaOH (17.22~17.83%) than other sources. Radial factors significantly affected ethanol-toluene extractive and lignin content. The ethanol-toluene extractive had the highest content (9.30~11.54%) at the outer part of heartwood while lignin content was the lowest (28.12~30.10%) in the inner part. The result indicated some good characteristics of young teak trees compared to the mature ones in relation to wood processing.

Abstract. Recent simulation studies have provided evidence that a pulsating aurora (PsA) associated with high-energy electron precipitation is having a clear local impact on ozone chemistry in the polar middle mesosphere. However, it is not clear if the PsA is frequent enough to cause longer-term effects of measurable magnitude. There is also an open question of the relative contribution of PsA-related energetic electron precipitation (PsA EEP) to the total atmospheric forcing by solar energetic particle precipitation (EPP).
Here we investigate the PsA-EEP impact on stratospheric and mesospheric odd hydrogen, odd nitrogen, and ozone concentrations. We make use of the Whole Atmosphere Community Climate Model and recent understanding on PsA frequency, latitudinal and magnetic local time extent, and energy-flux spectra. Analysing an 18-month time period covering all seasons, we particularly look at PsA-EEP impacts at two polar observation stations located at opposite hemispheres: Tromsø in the Northern Hemisphere (NH) and Halley Research Station in the Southern Hemisphere (SH). We find that PsA EEP can have a measurable impact on ozone concentration above 30 km altitude, with ozone depletion by up to 8 % seen in winter periods due to PsA-EEP-driven NOx enhancement. We also find that direct mesospheric NOx production by high-energy electrons (E> 100 keV) accounts for about half of the PsA-EEP-driven upper stratospheric ozone depletion. A larger PsA-EEP impact is seen in the SH where the background dynamical variability is weaker than in the NH. Clearly indicated from our results, consideration of polar vortex dynamics is required to understand PsA-EEP impacts seen at ground observation stations, especially in the NH. We conclude that PsA-EEP has the potential to make an important contribution to the total EPP forcing; thus, it should be considered in atmospheric and climate simulations.
FABM-NflexPD 1.0: assessing an instantaneous acclimation approach for modeling phytoplankton growth
Authors: Kerimoglu Onur , Anugerahanti Prima , Smith Sherwood Lan
Published: October 2021

Abstract. Coupled physical–biogeochemical models can generally reproduce large-scale patterns of primary production and biogeochemistry, but they often underestimate observed variability and gradients. This is partially caused by insufficient representation of systematic variations in the elemental composition and pigment density of phytoplankton. Although progress has been made through approaches accounting for the dynamics of phytoplankton composition with additional state variables, formidable computational challenges arise when these are applied in spatially explicit setups. The instantaneous acclimation (IA) approach addresses these challenges by assuming that Chl:C:nutrient ratios are instantly optimized locally (within each modeled grid cell, at each time step), such that they can be resolved as diagnostic variables. Here, we present the first tests of IA in an idealized 1-D setup: we implemented the IA in the Framework for Aquatic Biogeochemical Models (FABM) and coupled it with the General Ocean Turbulence Model (GOTM) to simulate the spatiotemporal dynamics in a 1-D water column. We compare the IA model against a fully dynamic, otherwise equivalently acclimative (dynamic acclimation; DA) variant with an additional state variable and a third, non-acclimative and fixed-stoichiometry (FS) variant. We find that the IA and DA variants, which require the same parameter set, behave similarly in many respects, although some differences do emerge especially during the winter–spring and autumn–winter transitions.
These differences however are relatively small in comparison to the differences between the DA and FS variants, suggesting that the IA approach can be used as a cost-effective improvement over a fixed-stoichiometry approach. Our analysis provides insights into the roles of acclimative flexibilities in simulated primary production and nutrient drawdown rates, seasonal and vertical distribution of phytoplankton biomass, formation of thin chlorophyll layers and stoichiometry of detrital material.
Mechanisms of coherent re-arrangement for long-lived spin order
Authors: Teleanu Florin , Vasos Paul R.
Published: October 2021

Abstract. Long-lived spin order-based approaches for magnetic resonance rely on the transition between two magnetic environments of different symmetries, one
governed by the magnetic field of the spectrometer and the other where this
strong magnetic field is inconsequential. Research on the excitation of
magnetic-symmetry transitions in nuclear spins is a scientific field that
debuted in Southampton in the year 2000. We advanced in this field carrying the baggage of pre-established directions in NMR spectroscopy. We propose to
reveal herein the part of discoveries that may have been obscured by our
choice to only look at them through the experience of such pre-established
directions at the time. The methodological developments that are emphasised herein are the mechanisms of translation between the symmetric and
non-symmetric environments with respect to the main magnetic field
B0. More specifically, we look again thoroughly at zero-quantum
rotations in the starting blocks of long-lived state populations,
magnetisation transfers between hyperpolarised heteronuclei, and protons. These pulse sequences seed subsequent magnetic mechanisms that contribute to further applications. For instance, we show how some of the introduced
coherence rotations were combined with classical pulse blocks to obtain two-dimensional correlations between protons and heteronuclei. We hope the pulse sequence
building blocks discussed herein will open further perspectives for magnetic resonance experiments with long-lived spin order.

Новый геополитический контекст взаимоотношений Армении и России в условиях изменения баланса военно-политических сил региональных и мировых держав в регионе
Authors: Vaskov Maksim
Published: October 2021

The purpose of the article is to consider various historical and political aspects that form the geopolitical context of Russian-Armenian relations. The author tried to take into account the factors that appeared as the consequences of Azerbaijan's aggression and the results of the Second Artsakh War.
Using the methods of factorial and system analysis the article studies various combinations of interaction between states, both directly located in the region and being global political players for which political processes in the Transcaucasia are only a part of more global political projects. The existing system of political relations is distinguished by instability and the formation of a new system of political and military risks. All participants in political relations have reasons to seek complications in Russian-Armenian relations. There are also threats for them in the context of the domestic policy of Russia and Armenia.
Overcoming these negative phenomena is a condition for the preservation and development of statehood in both Russia and Armenia. The development of a negative scenario will lead to new military conflicts and systemic crises of the entire Greater Caucasus.

Authors: Dave Yagnik , Sorani Dinesh , Patel Mital
Published: October 2021

Introduction: The instruments used to measure QOL are useful methods of transforming subjective measurements into objective data that can be quantified and analyzed, and are also important for assessing the impact of health care interventions on patient’s HRQOL. The uses of a self-administered scale in a specific localize/native language would make research and the clinical management more effective. It is advised that a self-reported measure is translated and adapted to the appropriate culture before it is used with subjects whose first language is not English. A Guajarati version of Quality of Life (MINICHAL) in essential hypertension would provide Guajarati community opportunity to communicate more effectively with their therapist. The availability of a self-administered scale in their native language makes clinical management and research more effective.
Methodology: In this observational study, 36 patients with essential hypertension from the Rajkot city included. MINICHAL-QOL was translated into Gujarati from English using Forward – Backward - Forward method. To ensure the face and content validity using group consensus method, each item was examined by group of 6 experts having mean experience of 8.78 years in the field of Physiotherapy.
Result: The total value of intra-class correlation coefficient of test–retest reliability was 0.988. Reliability estimated by internal consistency estimated a Cronbach's alpha of 0.879. The translated Gujarati version of MINICHAL-QOL demonstrated good reliability and validity. In validity specifically face validity and content validity suggests valid tool which can be applicable in essential hypertensive patients.
Conclusion: The results indicated that the Gujarati version of MINICHAL had been successfully translated from English to Gujarati. The translated Gujarati version of MINICHAL–QOL demonstrated good reliability and validity. So, it can be useful tools to measure quality of life in essential hypertensive patients specifically applicable for Gujarati population.
