Branquitude, racismo e sexismo em docências realizadas por mulheres negras no ensino de história
Authors: Meinerz Carla Beatriz , Santos Priscila de Souza , Pereira Priscila Nunes
Published: July 2021

Objetiva-se no texto analisar o ensino de história na formação inicial e continuada, através do estágio docente obrigatório em espaços escolares, tematizando o racismo institucional e o sexismo. O conceito de racismo institucional será interseccionado com o de sexismo, pois a análise destaca fenômenos observados com jovens estudantes negras, licenciandas do Curso de História da Universidade Federal do Rio Grande do Sul (UFRGS). Sob a perspectiva da abordagem qualitativa, consideram-se as práticas pedagógicas, construídas em processos de ensino e pesquisa, desenvolvidas a partir de autorreflexões e entrevistas abertas com estudantes negras em formação inicial. Problematiza-se a presença da branquitude, do sexismo e do racismo nas formas de viver e pensar essas práticas pedagógicas. Fundamenta-se em autoras como bell hooks, Grada Kilomba, Nilma Lino Gomes e Petronilha Beatriz Gonçalves e Silva, em associação com produções do campo específico do ensino de história no Brasil. As considerações parciais apontam a presença hegemônica das maneiras de agir e de pensar da branquitude no imaginário das comunidades escolares e universitárias, produzindo ações de discriminação racial e de gênero.
Relações étnico-raciais e de gênero em debate nos Ateliês de Pesquisa: (re)invenções nas Práticas Pedagógicas
Authors: Medeiros Marleide Alves de Oliveira , De Souza Vaneza Oliveira , Da Silva Ana Lúcia Gomes
Published: July 2021

Este artigo tem como objetivo discutir os principais resultados apresentados pelas pesquisas “Relações étnico-raciais e de gênero no contexto das práticas pedagógicas: escrevivências e (re)invenções na educação básica” e a pesquisa “Ensino de História e Cultura Afro-brasileira, Africana e Identidade: desafios e implicações nas Práticas pedagógicas”[1]. Dialogamos com os métodos adotados nas pesquisas, a etnoescrevivência e a pesquisa ação colaborativa, tomando os Ateliês de Pesquisa (APs) como dispositivo de construção de dados e intervenção, que possibilitou a construção de um movimento (auto)formativo e coautoral, pautado na colaboração e na reflexão sobre a prática. As discussões teóricas dialogam principalmente com hooks (2017); Lima (2015); Pimenta (2005); Silva e Costa (2020) e outros/as autores/as. Os resultados apontaram que ao tomar como centralidade as narrativas da experiência docente e suas histórias de vida no entrelace do desenvolvimento profissional, os APs provocaram deslocamentos nos processos formativos com os temas raça e gênero, produzindo reflexão e alteração nas práticas pedagógicas. Demonstraram ainda, que não basta ser colaborador da pesquisa para que a cocriação e coautoria se estabeleçam, é fundamental que o ethos da confiança, a relação ética e horizontal seja construída ao longo do processo, haja vista que o modus operandi dos Ateliês de Pesquisa prima pela horizontalidade, invenção e experiência ancoradas no real do cotidiano escolar como propulsoras da produção do conhecimento pedagógico considerado como conhecimento científico do campo da docência.
Ativismo Negr@: entrecruzando epistemologias feministas nas trajetórias de mulheres negras e religiosas
Authors: Fontes Manoelle Lopes , Pacheco Ana Cláudia Lemos
Published: July 2021

Neste artigo propomos discutir as trajetórias e encruzilhadas de mulheres negras adeptas do catolicismo e do candomblé, a partir da análise subsidiada por epistemologias situadas no campo do Ativismo Negr@, tomando como referência o feminismo negro e decolonial e a teologia feminista católica, procurando captar as narrativas sobre corpo, sexualidade, etnia, raça e religiosidade, de onde emergem intersecções. Para fazermos esse diálogo, contamos com as trajetórias de duas mulheres negras sul baianas, residentes no município de Canavieiras, autodeclaradas negras, com idades de 53 e 62 anos, sendo uma católica e outra candomblecista, respectivamente. As “trajetórias em narrativas” das duas colaboradoras da pesquisa nos revelaram encruzilhadas de pontos de vista sobre corpo e sexualidade, em que a religiosidade norteava a mobilização de diferentes conceitos e representações sobre o gênero. Nesse sentido, o corpo aparece narrado de diferentes formas, sobretudo como ferramenta para o acesso e a manutenção das práticas religiosas, que através da legitimação de elementos sacralizados permitem a efetivação e veiculação de crenças e valores que atravessam o campo da moralidade, afetando, assim, as percepções sobre os desejos e as práticas sexuais de mulheres negras.
Pedagógica da semente do movimento zapatista: semeadura e crescimento de um sujeito político coletivo
Authors: Sáenz Boldt Charlotte Marie , Barbosa Lia Pinheiro , Salazar Tania Cruz
Published: July 2021

En este artículo, se teoriza el proceso político-educativo-ético que proviene del Zapatismo y que se implementa afuera de sus territorios autónomos. Proponemos nombrarlo una Pedagógica de Semilla retomando el sentido multifacético que el filósofo Enrique Dussel le otorga a la pedagógica; y de semilla, por ser una educación política-ética que se va sembrando y que va creciendo a través de diversos encuentros e intercambios interculturales. Esta pedagógica va tejiendo una subjetividad colectiva de carácter político que lucha por una vida digna en común y que carga una potencialidad revolucionaria. Es parte de una continua resistencia sociohistórica de cara a sistemas y prácticas de dominación humana; un movimiento de movimientos que incluye tanto como transciende, luchas singulares. Esta Pedagógica de Semilla que está basada en la praxis Zapatista desde 1994 y su interlocución con el mundo exterior, busca integrar lo que una modernidad cartesiana y la imposición colonial han separado: saberes y relaciones entre comunidades humanas con la naturaleza de la cual son una parte integral. En este artículo, se teoriza la manera particular en la que esta pedagógica de semilla Zapatista propone, practica y avanza en relaciones y éticas políticas y socioecológicas.
ESTÁGIO SUPERVISIONADO E ENSINO REMOTO EMERGENCIAL: O (IM)POSSÍVEL E O INÉDITO O VIÁVEL EM UM CURSO DE LICENCIATURA EM LÍNGUA INGLESA
Authors: Araújo Lígia Cristina Domingos
Published: July 2021

Este trabalho apresenta um recorte de análises de uma pesquisa em andamento, na qual são discutidas experiências de estágio supervisionado de um curso de licenciatura de língua inglesa durante a implantação do Ensino Remoto Emergencial em uma universidade pública em Minas Gerais. Busca-se refletir sobre como instituição, professores e licenciandos construíram soluções para viabilizar a prática do estágio remoto durante a pandemia de COVID-19 à luz de um possível diálogo entre as noções freireanas de situação-limite e inédito viável e o aporte psicanalítico freudo-lacaniano com os conceitos de castração, real e impossível. O estudo sugere que a ação coletiva, com destaque para a atuação das professoras das disciplinas de estágio, viabilizou a prática remota dos estágios, mesmo com a identificação de limitações importantes, o que os remete à ideia de castração e à falha constitutiva da educação. Dessa forma, o reconhecimento da pandemia e seus efeitos enquanto marca de impossibilidade e não de impotência propiciou a emergência do inédito-viável, que se traduziu na construção de alternativas de ação para os contextos singulares de estágio.

Published: July 2021

Esta comunicación recoge un ejercicio de reflexión crítica al documentar la organización de la Práctica Pedagógica Investigativa (PPI) de un programa de formación de profesores durante la coyuntura que emerge de la pandemia por Covid-19. La PPI es un espacio formativo destacado por llevar al profesor en formación a ocupar el rol del profesor, para que desde esa posición construya saberes de la profesión. De allí, la importancia de reflexionar sobre las formas en que este espacio se configuró en la pandemia. La documentación de la PPI se realizó a partir del análisis de: 1) el plan de estudios del programa de interés, 2) los microcurrículos de las unidades temáticas (cursos) que conforman la PPI, 3) una encuesta a estudiantes de las unidades temáticas, y 4) una encuesta realizada a los profesores de las unidades temáticas. Las encuestas se recabaron con etnografía virtual. Como hallazgos se encuentra que la PPI se modificó haciendo énfasis en el ejercicio de la planeación y la innovación relacionada con el uso de materiales y plataformas tecnológicas. La articulación de la teoría y la práctica se ven restringidos a pilotajes y estudios de casos con pequeños grupos.
CONTRIBUTOS EMER(UR)GENTES PARA A CONSTRUÇÃO PROFISSIONAL DOS EDUCADORES/PROFESSORES – REFLEXÕES EM TEMPOS PANDÉMICOS
Authors: Sarmento Teresa , Silva Carlos
Published: July 2021

A formação de professores obriga à mobilização e articulação de diferentes tipos de saberes, de ordem pessoal e profissional. Tornar-se professor é, assim, um processo individual e coletivo que exige a simbiose interna da ação, da experiência e da emoção, no sentido de se constituir como uma ação total de uma pessoa no desempenho de uma profissão específica. O presente texto parte de uma abordagem sobre princípios basilares da formação de professores, de índole humanista/reconstrutivista, assim como de uma detalhada reflexão em torno do que consideramos por princípios curriculares para a formação, com base em propostas ou ideias inspiradoras (inovadoras) de sentido disruptivo com o estabelecido. O estágio é um núcleo central no processo formativo, pelo que é aqui especialmente mencionado. Este é desenvolvido com o suporte de uma rede colaborativa constituída pelo(s) estagiário(s), o professor cooperante e o professor supervisor, num processo de colaboração, ação e reflexão, em que a investigação pedagógica aporta um significado muito relevante. Terminamos o texto com um sentido de emer(ur)engência relativa à formação, com uma reflexão induzida pela auscultação sobre algumas perceções de estudantes candidatos a educadores e professores no contexto pandémico, que se repercutem em lógicas já consolidadas da premência de redes colaborativas para a construção profissional, que nos levam a uma última ponderação, em jeito de síntese, sobre contributos de como podemos caminhar no sentido da formação de professores.
ESTÁGIO SUPERVISIONADO NO CONTEXTO DO ENSINO REMOTO EMERGENCIAL: ENTRE A EXPECTATIVA E A RESSIGNIFICAÇÃO
Authors: Ferraz Roselane Duarte , Ferreira Lúcia Gracia
Published: July 2021

O artigo traz um estudo de abordagem qualitativa em que intenciona analisar os sentidos do estágio supervisionado no ensino remoto, a partir de aspectos formativos-pedagógicos de alunos/as-estagiários/as. Trata-se dos Estágios em Educação Infantil e Anos Iniciais do Ensino Fundamental, componentes curriculares obrigatórios do curso de licenciatura em Pedagogia, da Universidade Estadual do Sudoeste da Bahia, Itapetinga, no ano de 2020. Metodologicamente, foram analisados os diários de bordo apresentados como relatório final dos estágios, bem como os dados provenientes dos fóruns de discussão ocorridos no decorrer dos estágios. Utilizamos a técnica da análise de conteúdo, através da análise temática (BARDIN, 2010). Os resultados apontam que as expectativas dos estagiários evidenciaram os aspectos constitutivos do estágio, considerando essa etapa formativa como um campo de construção dos saberes docentes, de ressignificação das práticas de ensino e aprendizagem. Os sentidos de estágio são tecidos quando os graduandos ao revelarem suas expectativas sobre uma perspectiva de estágio que não se materializou e, quando ressignificam o modo como este aconteceu, colocam em pauta a formação docente no contexto do ensino remoto.

Adipose tissue (AT) is a key metabolic organ which functions are rhythmically regulated by an endogenous circadian clock. Feeding is a “zeitgeber” aligning the clock in AT with the external time, but mechanisms of this regulation remain largely unclear. We tested the hypothesis that postprandial changes of the hormone insulin directly entrain circadian clocks in AT and investigated a transcriptional-dependent mechanism of this regulation. We analyzed gene expression in subcutaneous AT (SAT) of obese subjects collected before and after the hyperinsulinemic-euglycemic clamp or control saline infusion (SC). The expressions of core clock genes PER2, PER3, and NR1D1 in SAT were differentially changed upon insulin and saline infusion, suggesting insulin-dependent clock regulation. In human stem cell–derived adipocytes, mouse 3T3-L1 cells, and AT explants from mPer2Luc knockin mice, insulin induced a transient increase of the Per2 mRNA and protein expression, leading to the phase shift of circadian oscillations, with similar effects for Per1. Insulin effects were dependent on the region between −64 and −43 in the Per2 promoter but not on CRE and E-box elements. Our results demonstrate that insulin directly regulates circadian clocks in AT and isolated adipocytes, thus representing a primary mechanism of feeding-induced AT clock entrainment.
Love in Dionysius the Areopagite and St Maximus the Confessor
Authors: Louth Andrew
Published: July 2021

Love (erōs, agapē) is a fundamental category in the sixth-century Dionysius the Areopagite and the seventh-century Maximus the Confessor, the latter being confessedly dependant on the former, and both formative for the later Byzantine tradition. Both are indebted to earlier thinkers, both pagan thinkers such as Plato, Plotinus, and Proclus, and Christian thinkers such as Origen and the Cappadocian Fathers. Dionysius’s teaching on love presents a fundamentally metaphysical account, with cosmic entailments. He assimilates the two Greek words for love, erōs and agapē, seeing them both as manifestations of beauty and responses to beauty, and using them more or less interchangeably for the ecstatic love of God for the cosmos and the love that underlies the creatures’ return to union, to the One. Maximus shares Dionysius’s sense of love as metaphysical and cosmic, but his teaching is much more practical, and presents love as something that can be attained by the Christian or monk, though it requires genuine ascetic struggle. He makes more of a distinction between erōs and agapē than Dionysius, seeing erōs as perfecting the soul’s desire, while agapē perfects the soul’s thumos, psychic energy. Maximus’s understanding of the interrelated psychological makeup of the soul, influenced by Evagrius, though with its own characteristic emphases, also underlies his sense of what is meant by the restoration of the cosmos.

PT. Elastis Reka Aktif including companies engaged in manufacturing made from rHDPE (recycling High Density Polyethylene). The problem that often occurs is that the achievement of the Not Good Key Point Indicator exceeds the tolerance given by management by 1%. Therefore, improvements were made using the Six Sigma method and the Failure Mode Effect Analysis method in order to get the priority of improvement targets. The first improvement proposal given to the company is for RPN 280, namely the material characteristics are not homogeneous by proposing a re-design of the silo which is in the pelletizing process and the fourth is RPN 252 where the roll takeup and winder positions are not parallel, namely by providing area boundaries in order to minimize the position not being aligned. parallel. After providing a proposal for each potential problem and socializing it to the production side, it is hoped that it can reduce the reject rate in the blowing process.

Published: July 2021

The challenges of using locally available materials in Nigeria to meet the tiles demand that will be affordable and compete favourably with imported products will no doubt not only contribute to our Gross Domestic Product but also meet the yearning of the Federal Government on her local content policy. This necessitated this study to aim at the production of ceramic floor tiles with clays modified with naturally occurring materials. An experimental method was adopted to carry out this research work. Different clay samples were purposively gotten from Mbaukwu town, Anambra State, Nigeria. Rice husk, silt, feldspar, quartz was obtained to serve as modifiers. An elaborate nested experimental design, structured as an analytical hierarchy process, and festooned with three base materials, 4-modifiers, and with replications, facilitated the achievement of the production. The nested design was developed to guide in the optimum combination of materials that will give the best yield of tiles. The base materials were used in combination with the four modifiers at different percentage levels. The tiles produced were subjected to same test in order to ascertain their behavior in terms of weather, resistance to abrasion, compatibility with mortar, water absorption, dilute acid, Sodium Hydroxide and detergent. The experimental tiles produced compete favorably with any foreign product as it was seen to match up with “Vetrified tiles” and “Gomex tile” from Italy and satisfies NIS 427: 2000. Glazed ceramic floor tiles have been successfully manufactured locally using clay and other naturally occurring materials and it has given excellent performance characteristics.

Published: July 2021

This paper discusses the dynamic modelling of a solar energy system with vehicle to home (V2H) option for Newfoundland condition. A location was chosen (13 Polina Road) in St. John’s, Newfoundland, Canada. Using BEopt, Homer and MATLAB software, an optimized system was designed for the chosen site to satisfy the house’s energy demand. Furthermore, the concept of V2H is also implemented with aid of smart current sensors installed in the house. When the power provided by the PV panel and the stored energy in the inhouse battery is less than the load’s energy demand, the Nissan Leaf’s battery used to supply home loads in V2H operation mode. The system operates based on the information generated by the sensors. Detailed system dynamic modelling is also presented along with the simulation results. Eight system control modes are proposed and simulated.

Assessing the Impact of Changes on Design and Material of Howe Bridges by Finite Element Analysis
Authors: Martins Jairo Aparecido , Romão Estaner Claro
Published: July 2021

This paper presents an investigation of changes on design and material of a Howe bridge under vertical loads. Specifically, it aimed to find out how small changes on Howe bridge design and material affected von Mises stresses as well as stresses at Z direction. As a method, it was used a finite element analysis (linear-elastic) by Autodesk F-360. Half of a bridge was designed (one bridge side) and loaded with a central higher load and two equal smaller lateral loads. In essence, von Mises stresses (s) and stress at Z direction (sz) decreased on stresses values until a certain design change, which was proportional to a raise of mass due to beams added on the trusses. With a change of material to a lighter metal, from steel to aluminum, it was possible to overcome the mass drawback brought by steel and utterly possible to end up for a more effective design for a Howe truss bridge by applying minimal design changes.
Pengaruh Latihan Fisik terhadap Perbaikan Resistensi Insulin
Authors: Sukarno Devitya Angielevi
Published: July 2021

Abstract--Insulin resistance underlies the pathogenesis of chronic disease, such as diabetes mellitus which has high morbidity and mortality rate. Insulin resistance is a pathological condition when cells fail to respond normally to the insulin hormone, because of insulin signaling pathway disruption. Bound between insulin and insulin’s receptor cannot phosphorylate tyrosine and fail to activate insulin receptor substrate-1 (IRS-1). This failure decrease Glucose transporter-4 (GLUT-4) expression on the skeletal muscle’s cell membrane, that leads to decrease glucose influx and increase blood glucose level. A routine physical training which does according to adequate training dose, will activate adenosin 5’monophosphate-activated protein kinase (AMPK) and lead to the translocation of GLUT-4 vesicles without insulin and insulin’s receptor bonding.GLUT-4 expression on the skeletal muscle’s cell membrane which is stimulated by muscle contraction will increase glucose influx and decrease blood glucose level.

Keywords: insulin resistance; physical training; insulin signaling pathway

 

Abstrak--Resistensi insulin merupakan penyebab yang mendasari terjadinya penyakit kronis seperti diabetes melitus yang memiliki angka morbiditas dan mortalitas tinggi.Resistensi insulin merupakan keadaan patologis dimana terjadi kegagalan respon seluler terhadap hormon insulin akibat gangguan pada jalur sinyal insulin.Ikatan insulin pada reseptornya tidak dapat menyebabkan fosforilasi tirosin sehingga tidak dapat mengaktivasi insulin receptor substrate-1 (IRS-1). Kegagalan aktivasi tersebut akan menyebabkan penurunan ekspresi Glucose transporter-4 (GLUT-4) pada membran sel otot rangka sehingga ambilan glukosa oleh sel menurun dan glukosa darah meningkat. Latihan fisik yang dilakukan secara rutin, teratur dan sesuai dengan dosis latihan yang tepat dapat mengaktivasi adenosin 5’monophosphate-activated protein kinase (AMPK), sehingga menyebabkan translokasi vesikel berisi GLUT-4, tanpa melalui ikatan insulin dengan reseptornya. Ekspresi GLUT-4 pada membran sel yang dirangsang oleh kontraksi otot akan meningkatkan ambilan glukosa dan menurunkan glukosa darah.

Authors: Chourasia Avin S. , Dalei Narendra N. , Jha Karunakar
Published: July 2021

Examining the interrelationships between critical success factors (CSFs) is of importance for the successful development of PPP airports. Many studies are available for the identification of CSFs for infrastructure projects, but very limited research have been conducted so far on investigating the interrelationships between the CSFs of PPP airports. The study is based on the institutional theory, which considers the exploration of the relationships between different institutional factors. The results show that Process Characteristics have comparatively more impact on Public Characteristics and, similarly, Cooperative Environment has more impact on Process Characteristics. However, Process Characteristics have a less significant impact on Private Characteristics. The study also revealed that to achieve high-quality services and the protection of public interest under a PPP mechanism, proper government supervision is required. Moreover, customers’ satisfaction and their opinion are also responsible for the achievement of high-quality services and better value for money.
Idéburen sektorssamverkan med Malmö universitet
Authors: Sjölander Jens , Brunnström Pål
Published: July 2021

Den här rapporten är en delrapport inom ramen för det Vinnovafinansierade projektet Strategiska partnerskap för effektiv och transparent samverkan (Spets) och belyser Malmö universitets samverkan med organisationer inom den idéburna sektorn. Rapporten bygger på en intervjustudie med tio idéburna organisationer, och speglar samverkan med Malmö universitet ur deras perspektiv: vilken samverkan som bedrivs, vad den ger organisationerna, utmaningar och hinder samt möjlighet för utveckling av samverkan, till exempel genom ett strategiskt partnerskapsavtal.Rapporten visar att det på Malmö universitet sker en hel del samverkan både kopplat till forskning, utbildning och nyttiggörande och att denna samverkan när den sker i relation till idéburen sektor främst är kopplad till tre av universitetets fakulteter – Fakulteten Kultur och samhälle, Fakulteten Hälsa och samhälle samt Fakulteten Lärande och samhälle. De intervjuade organisationernas motiv för samverkan med universitetet varierar, och undersökningen indikerar att organisationerna ser samverkan som ett sätt att fylla behov av kunskap och kompetensförsörjning, att genom vänlig kritik stimulera till nytänkande, samt att ge organisationerna ökad legitimitet i deras arbete för samhällsförändring. Undersökningen visar att det finns behov av ökad systematik i samverkan och att mer skulle kunna göras för att stärka samverkan kring forskning och utbildning. De intervjuade organisationerna lyfter behovet av mer forskning om och tillsammans med den idéburna sektorns organisationer och behovet av mer samverkan kopplat till studenters uppsatser och praktik. Här finns en möjlighet att möta organisationernas behov av kunskap, kompetens och framtida personal. Det finns även ett behov av fler arenor för möten, gärna regelbundet återkommande, mellan universitetet och den idéburen sektor, och organisationerna efterlyser även generellt ökade kunskaper om den idéburna sektorns särart, förutsättningar och behov, inom akademin såväl som i samhället i stort. Undersökningen belyser även behovet av utökat stöd och finansiering för forskare som samverkar med idéburen sektor, då finansiering av samverkan är ett särskilt problem.

Published: July 2021

The objective of this research is to select the most suitable drilling location of new groundwater exploration wells, with a decision-making tool from Geographic Information System (GIS). The optimum location will be evaluated base on the hydro-geoelectrical parameter derived from Vertical Electrical Sound (VES) including Longitudinal Conductance, the thickness of the aquifer, the apparent resistivity and Transmissivity. From the Geo-electrical method (VES) the finds shows that the aquifers in the study area have Apparent Resistivity ranging from 0.32 to 40.24 Î©m, Thickness between 0.21 m to 15.06 m, Longitudinal Conductance ranging from 0.006 to 10.246Î©-1 and Transmissivity ranging from 0.14 to 10.38m2/day. Hydro-geoelectrical data were integrated into GIS to precisely determine the best location for groundwater borehole. Finally, the study location was classified into three classes; not suitable, moderately suitable and highly suitability with respect to the input factors using the Fuzzy overly combing method. Itâ€™s evident that the middle part of the area in study represents the optimum location for the drilling of groundwater boreholes.

Authors: Ali Kamal K. , Ibraheem Reem Kh. , Thabit Hassan A.
Published: July 2021

Coherent noise such as ground roll and guided wave is present in the seismic line DE21 (East Diwaniya south eastern Iraq) and it obscures seismic signal and degrades from the quality of data. To attenuate the coherent noise from the shot gather and the Stack of the seismic line, AGORA filter was applied in order to obtain the good signal as the hyperbola shape in shot gather and the reflectors will be clearly to interpret it later. It has given good results and the coherent noise was attenuated in high ratio on all the line. The spectrum analysis is confirmed the effectiveness of AGORA filter to attenuate the coherent noise.
Quantum Key Distribution and Chaos Bandwidth Effects on Impact Security of Quantum Communications
Authors: Al Hasani Mahdi H. , Al Naimee Kais A. M.
Published: July 2021

The influence of bias current on the bandwidth of chaotic signals in semiconductor lasers by optical feedback has been studied experimentally and numerically. The measured data reveal that the bandwidth increase when the system becomes chaotic and this chaotic signal has a broadband spectrum so it can be used as a carrier for the quantum key. Mixing chaotic signal and quantum key make a very small change in chaotic bandwidth that does not affect the security of data transmitted.

Authors: Majeed Amjed A. , Al-Aubydi Mouruj A.
Published: July 2021

Klebsiella pneumoniae is one of common hospital-acquired bacteria causing nosocomial pneumonia, urinary tract infections, and intra-abdominal infections. The aim of this study is investigating the Modulation effect of Zinc Oxide nanoparticles (ZnO NPs) against multidrug resistant K. pneumonia which was isolated from Respiratory Tract Infections (RTIs). The results of isolation and characterization of bacterial specimens showed that 20.81% of RTIs were Klebsiella pneumoniae. The strongest isolate showed resistant for most usable antibiotics selected. Simultaneously, ZnO NPs were produced by an aqueous extract of Green Tea leaves as a reducing and stabilizer agent. The Ultraviolet-Visible (UV-Vis) spectrum was indicated a successful production of ZnO NPs at 383 nm. X-Ray Diffractometry (XRD) pattern showed peaks at 2Î¸ positions matching to standards and indicating a formation of hexagonal (wurtzite) shape of ZnO NPs, with an average size of 22nm. Fourier Transform- Infrared (FT-IR) spectra of ZnO NPs revealed the participating of Green Tea biomolecules in the synthesis process. The minimum inhibitory concentration (MIC) of ZnO NPs against K. pneumoniae was 3.2 mg/mL. The results of using nanoparticles showed a morphological changing in K. pneumoniae colonies, and a modulation effect occurred against some antibiotic resistance of Klebsiella pneumoniae such as Gentamycin and Levofloxacin.

Published: July 2021

16 March of every year marked the anniversary of the chemical gas attack on the City of Halabja, Kurdistan, Iraq, and its nearby villages. In the process, 5000 people reportedly died from the attack. Many more were wounded and the event left nearly 60 000 people displaced. A perceived consequence of the chemical bombing of Halabja City was the environmental pollution of the soil and water. A recent questionnaire completed by the population of Halabja City indicated that 35% believed that water pollution was still an issue, and 55% thought that soil pollution posed a high risk.In 2016, were requested by the Halabja City governor to investigate the situation. And to lay to rest the perception and concerns of soil and water still being contaminated by the events that happened on that day in March 1988. A total of 8 soil and 18 water samples were collected, Soil samples were collected from thesurface and as close as possible to bomb sites and craters, in contrast, water samples were collected from seven springs, ten water wells, and one surface streams downslope as close as possible to the bombed areas. The samples were analyzed for chemical warfare agents which are Arsenic, Cyanide, Fluoride, soluble  orthophosphate, Nitrate, Phosphorous, Sulphate, and Sulphur. The results indicated no negative contamination remaining in both water and soil. The geology and hydrogeology in the area played an important role in helping the chemical warfare agents (CWA) to degrade during the past 28 years. Most of the CWA used arewater- soluble and solubility increases when the agents are either hydrolyzed or oxidized. The hydrolysis products have equal toxicity to the parent chemicals, posing a similar threat to the environment. In contrast, the intact chemicals can be adsorbed onto sediment, where they can be stored for a longer time.

Published: July 2021

Age is a predominant parameter for arbitrating an individual, for security and access concerns of the data that exist in cyber space. Nowadays we find a rapid growth in unethical practices from youngsters as well as skilled cyber users. Facial image renders a variety of information that can be used, when processed to ascertain the age of individuals. In this paper, local facial features are considered to predict the age group, where local Binary Pattern (LBP) is extracted from four regions of facial images. The prominent areas where wrinkles are developed naturally in human as age increases are taken for feature extraction. Further these feature vectors are subjected to  ensemble techniques that increases the accuracy of the model hence improving the efficiency in terms of MAE and performance parameters for age group classification. The proposed approach was evaluated on FG-NET facial aging dataset.
