Authors: RAM HARDEV , KUMAR RAKESH , MEENA RAJESH KUMAR , MALIK RAMAN , MALLIKARJUN MALLIKARJUN , SAXENA ANURAG
Published: August 2022

A field experiment was carried out during kharif 2016 and 2017 at ICAR-NDRI, Karnal to evaluate the effect of tillage and nitrogen management on productivity, quality and profitability of baby corn (Zea mays L.). The experiment consisted of 18 treatments comprising three tillage practices, viz. zero tillage (ZT), conventional tillage (CT) and raised beds (RB) as main plots while six nitrogen (N) management practices, viz. control, N75%, N75+Azotobactor, N100%, N100+Azotobactor and N125% were assigned in sub-plots in split plot design with three replications. Among tillage practices, RB showed significantly higher yield attributes, yield, green fodder (376.7 q/ha) and baby cobs yield (10.3 q/ha) over CT (346.7 and 8.38 q/ha) and ZT (363.6 and 9.36 q/ha). Among the N management options, increasing N levels increased growth and yield attributes and yield up to 100% N with application of Azotobactor. The maximum pooled cost of production was recorded under CT followed by RB and lowest in ZT. However, mean net return was observed highest under RB (`111.9 lakh/ha) followed by ZT (`103.6 lakh/ha) and lowest in CT (`89.3 lakh/ha). The saving in total cost of cultivation due to ZT was `900 to 2,500/ha, as compared to RB and CT, respectively. Hence, to realize higher productivity, profitability and sustain soil health, baby corn planted under raised bed with application of 100% N with azotobactor was quite cost efficient, this can further strengthen and sustain the performance of livestock in terms of quality green fodder availability.

Published: August 2022

INTRODUÇÃO: A lesão renal na COVID-19 ainda não está totalmente elucidada, mas sabe-se que ela é diversa e multifatorial. Os maiores estudos realizados apontam a prevalência de alguns fatores de risco associados à uma maior propensão para o desenvolvimento da lesão renal. Além disso, tem sido discutida nesse cenário a importância da avaliação e detecção precoce da lesão renal, o que auxiliaria na predição de prognóstico e, ainda, o desfecho clínico durante o tratamento da infecção pelo vírus. MATERIAIS E METÓDOS: O presente estudo trata-se de uma revisão da literatura. Os dados apresentados provêm de artigos científicos publicados entre os anos de 2019 e 2020. A busca de artigos científicos foi realizada nos bancos de dados SCIELO, PUBMED. DISCUSSÃO: Sabe-se que vários são os fatores envolvidos na relação entre COVID-19 e lesão renal, desde danos diretos causados pelo vírus até mecanismos inespecíficos que desencadeiam uma série de prejuízos à saúde. Além disso, quando associado a fatores de risco como idade avançada e hipertensão a infecção pelo coronavírus pode ocasionar complicações renais e aumento da mortalidade. Desse modo, faz-se necessário o desenvolvimento de mecanismos para realização de uma investigação minuciosa do estresse renal causado pelo vírus com o intuito de auxiliar no diagnóstico precoce e na prevenção de quadros mais graves. Ainda assim, a recuperação da função renal é difícil e necessita de um acompanhamento com especialista para monitoramento da sua evolução. CONCLUSÃO: Por mais que diversos artigos tenham sido publicados, ainda se faz necessário o desenvolvimento de maiores estudos que determinem com segurança os mecanismos fisiopatológicos, a detecção precoce da lesão renal e o seu manejo específico.

Published: August 2022

Objetivos: Relatar o número de casos da raiva na região Nordeste no período de 2013 a 2017 e identificar aspectos correlacionados ao panorama epidemiológico da sua distribuição. Metodologia: Foram utilizados para a coleta de dados informações do Sistema de Informação de Agravos de Notificação (SINAN). Resultados: A região Nordeste foi responsável por mais da metade dos casos confirmados de raiva humana no Brasil (67%). A maioria dos casos no Nordeste acometeram pessoas do sexo masculino (89%), adultos com faixa etária de 20-39 anos (56%), residentes de áreas urbanas (56%), sendo a maior parte das agressões feitas por animais não vacinados (80%). Conclusão: A raiva humana no Nordeste parece estar atrelada a baixos índices de desenvolvimento humano, falta de informações a respeito das vias de infecção e gravidade da doença, inadequada profilaxia de pós-exposição e interrupção do tratamento. Além disso, a possível subnotificação de casos suspeitos dificulta as ações das autoridades de saúde locais.

One of the most important stages in root canal treatment is shaping. Manufacturers have developed various equipment and techniques to achieve better shaping abilities This study aims to evaluate the effects of 3 different rotary file systems, produced with the different heat-treated NiTi alloys technology on root canal transportation and centering ability via CBCT. A total of 36, Vertucci Type IV mesiobuccal (MB) root canals of mandibular molars were used. After pre-instrumented CBCT images were taken, the samples were randomized according to initial canal curvature angles into three groups (n=12). Root canal instrumentation was completed according to the manufacturer’s instructions in all groups (VDW.Rotate, K3XF, Hyflex EDM). Post-instrumented CBCT images were taken. The root canal transportation and centering ability was calculated according to the Gambill et al described before (1996). Statistical analysis was performed using the IBM Statistics SPSS 20.01 program. One-way ANAVO and post-hoc Tukey tests were used for evaluating the differences among the groups. The significance level was set at P=0.05. There were no statistical differences at any level on canal transportation and centering ability according to groups. However, the tendency to transportation changed according to differences in horizontal levels. In conclusion, all systems produced similar canal transports in the mandıbular molar canals and these systems were all clinically acceptable limits.

QUEER-PROBLEMS AS A FACT OF AESTHETICS IN THE WORKS OF OLES ULIANENKO
Authors: SHTEINBUK Feliks
Published: August 2022

The purpose of the research is to establish why the author uses images of queer identities on the example of Oles Ulianenko’s works. The research methodology is based on the hypothesis that to achieve the specified goal should be possible providing the three methods are used, namely hermeneutic, the comparative-typological, and the corporal- mimetic method to analyse fiction. The scientific novelty of the research is that queer issues are represented as an aesthetic phenomenon in Ukrainian literary studies for the first time. The Conclusions. First, the queer content depicted in the works under analysis proves that people find their ability to derive pleasure from various actions, ideas, fantasies, and things, related to sexual sphere, extraordinary significant. Second, the ability and desire to receive pleasure can be limited neither by laughter nor by the death threat, which ontologically should allegedly deny sexual urges. Third, direct portraying of people’s conflicting abilities and desires is specific aesthetics. Fourth, queer content does not exist by itself since it is an inevitable peculiar accompaniment of passion, being a queer phenomenon which violates not a fancy moral but a real rational norm. Fifth, the works by Oles Ulianenko are artistically powerful because he does not neglect anything Queer-problems as a fact of aesthetics in the works of Oles Ulianenko ISSN 2824-1843 (Online), ISSN 2824-8074 (Print) 57 in his desperate attempts to reach extreme aesthetic limit, opening almost unlimited horizon of senses which is completely different, much deeper than any ideological, political, or pedagogical speculation. Sixth, this horizon is determined by a wonderful and simultaneously imperfect, and exciting artistic strategy, caused by queer efforts to overcome the last limits of erotic and sexual decency, as a result of which such incredible aesthetics appears.

Published: August 2022

This study focuses on a short-term pedochronosequence of Kurgan № 1 at the Boldyrevo IV kurgan cemetery in the Orenburg Region of the Southern Cis-Urals. According to archaeological findings, the kurgan was built over several decades by people of the Yamnaya (Pit-Grave) culture of the Early Bronze Age (around 5500 BP), with the exact time of its building to be confirmed by radiocarbon dating and further archaeological information. A comparative analysis of the four earthen constructions of the kurgan and the paleosols buried under those constructions was conducted. Results suggest that the kurgan building period was accompanied by the following changes in paleosol morphology and physicochemical properties: the humus horizon acquired a tonguing-like lower boundary, decreased organic carbon content and magnetic susceptibility, while the whole profile was characterized by increasing degree of zooturbation; the impregnation by carbonates in the middle part of the profile and the contents of carbonate carbon, gypsum, and exchangeable sodium increased. Similar trends of morphological and physicochemical changes were observed in the materials of the kurgan constructions. Based on these findings it can conclude that the climate went through aridization rise during the period of the kurgan building. The paleobotanical data from palynological and microbiomorphic analyses indicate that there was a tendency for paleoclimate aridization and, possibly a cooling trend during the studied period of the Yamnaya culture, which was probably more arid than the modern climate.
ANTHROPOCENTRISM AND THE EXPLOITATION OF NATURE: AN ECOCRITICAL ANALYSIS OF JOSEPH CONRAD'S HEART OF DARKNESS
Authors: Caleb Monday Jonah
Published: August 2022

One of the defining eras in the history of mankind is the Age of Enlightenment. While it acted as a bridge between contemporary times and the classical and the medieval epochs of mankind's existence, it ushered in new forms of challenges that the modern society is grappling with, among which the depletion of nature, occasioned by wanton exploitation, is one. Among other creeds of the Age of Enlightenment is the focus on reason as the source of authority. It is also known that the ability to reason resides with humans and humans' ability to reason, among others, account for the promotion of a human centred view of the universe, which further gave impetus to the rise and growth of science and technology. This advancement affects all other aspects of existence, including the non-human world. Thus, using the ideological postulations of ecocriticism, this paper examines how the view of humans being the point of reference of existence empowers the mind to exploit the non-human world as well as other humans. From the analysis, this paperdiscovers that by elevating human experience and values as the loci of the universe, humans assume a god-father status over the elements of nature. This depletion is made possible through the instrumentation of science and technology. This paper concludes that the anthropocentric views ushered by the Age of Enlightenment empowered humans to explore and subsequently exploit the non-human world. Due to this, there is a need to move from an anthropocentric perception of the universe to a nature oriented view of existence in a bid to save the earth both for the present and the future.
The Niger Delta and the Quest for Street Politics in Jowhor Ile’s "And After Many Days"
Authors: Akung Jonas , Nathaniel Ojima
Published: August 2022

This article examines the protest tradition in the Nigerian Niger-Delta fiction and advocates for the necessity of street politics as an alternative to a mere expression of anger; using Jowhor Ile’s debut and adroit novel, And after many Days (2016), which won the Etisalat Prize for literature in 2017. The article adopts the qualitative research method to explore the dimensions of violence meted on the people of the region. It argues that street politics will suffice in alleviating the region’s problems. Street politics is the politics of dissent and active non-compliance which tends to arm the people for active resistance against the forces of exploitation. Using postcolonial ecocritical lens, the article contends that multi-national companies operating in the region connive with local political leaders to rob the people of their God-given resources. The paper concludes that if the region’s crisis must be addressed, internal colonialism must be dealt with, and this can only be achieved by the creation of active dissidents, through street politics, similar to the Arab Spring.
Discursive Construction of Synonymous Relations in Political Speeches
Authors: Prof. Akin Odebunmi  , Dr. Funke Josephine Oni
Published: August 2022

Abstract

Existing studies on political discourse have investigated the role of language in propaganda, the emotive use of language by politicians, the ideological undertone of modal verbs in political speeches, often ignoring the discursive use of synonyms, especially in the Nigerian context. This paper thus examines the discursive construction of synonyms in selected speeches of former Nigerian president, Olusegun Obasanjo with the aim of identifying the ideological implication of the synonymous construction in the speeches. His speeches are worth studying as he was the first military head of state to be elected a civilian president, thereby leading the country on two good occasions. Twelve speeches were purposively sampled comprising those he made as a military head of state and as a civilian president. These periods are important in Nigeria’s political history. The study adopted evaluative semantics and sociocognitive approach of critical discourse analysis as theoretical basis.  The former accounts for the synonymous relations in the speeches and the latter, their ideological import. The findings show that the synonymous relations represent optimism and expectations from individual, society and institution. Synonyms related to optimism are characterised by government’s commitment to positive change, transformation and hope, while synonyms that relate to issue of expectation from the individual, the society and institutions are characterised by societal development, forbearance, disorder, healthy information management and dissemination, and negative practices and values. Thus, these synonymous relations, when considered together with the co(n)text, reflect Obasanjo’s reformist agenda.
The developing link of metabolic growth factors in insulin resistance

Published: August 2022

Obesity has become a major problem in public health over the past few years. It is strongly associated with insulin resistance, the central pathological process in many metabolic disorders. Now it is generally acknowledged that adipose tissue plays a vital role in the obesity-induced insulin resistance as an active endocrine organ. Many “classic” adipokines such as TNF-α, IL-6, adiponectin, and leptin have been studied extensively but recently many novel metabolic regulators which belong to growth factor family, such as FGF21, VEGF, TGF-β superfamily, have gained much attention. While some of these growth factors have showed greater promise in palliating insulin resistance and type 2 diabetes mellitus (T2DM), the role of others’ remains obscure or shrouded in mystery due to their pleiotropic nature. Plethora of research has been reported to trace their role in insulin-resistance in peripheral insulin-responsive tissues, like adipose tissue and skeletal muscle. In this review we attempted to analyze the role of various growth factors in insulin resistance as a result of mutual cross-talk between metabolic tissues.

Sistemas de Reputação, bastante usados em redes P2P, têm como objetivo a avaliação individual de peers, baseando-se nas suas interações prévias. Tais sistemas podem ser utilizados para garantir a segurança em nível de serviços. Este artigo propõe o uso de um Sistema de Reputação orientado a serviços e baseado em lógica nebulosa, como forma de aumentar o nível de segurança dos serviços trocados entre estações. O artigo apresenta a descrição do sistema proposto, o cenário de aplicação e as simulações realizadas para sua avaliação.
Quebrando a Barreira entre Mecanismos de Segurança através da Composição de Serviços Web: Uma Arquitetura para Detecção de Ataques Distribuídos e de Múltiplas Etapas
Authors: Fagundes Leonardo Lemes , Gaspary Luciano Paschoal
Published: August 2022

Nos últimos anos tem se observado o avanço de ataques planejados, como DDoS, compostos de múltiplas etapas e partindo de diversos hosts. As soluções mais tradicionais para detecção de intrusão não estão preparadas para lidar com essa natureza de ataque devido, entre outros fatores, à carência de mecanismos para comunicação uniforme com diferentes sistemas de segurança (ex: IDS, firewall, etc.) e para correlação, em tempo hábil, dos eventos observados. Para suprir tal lacuna, este artigo propõe uma arquitetura orientada a serviços para detecção de ataques distribuídos e de múltiplas etapas. A arquitetura foi desenvolvida com base no padrão WSDM (Web Services Distributed Management) e avaliada experimentalmente usando cenário de ataque DDoS proposto pelo MIT Lincoln Laboratory.
A new probabilistic public key algorithm based on elliptic logarithms
Authors: Araujo Neto Afonso Comba de , Weber Raul Fernando
Published: August 2022

This paper introduces a new probabilistic public key algorithm based on elliptic curves and show that it is secure. The security of the scheme is solely based on the difficulty of the elliptic curve discrete logarithm problem while at the same time it has a constant message expansion for one encryption of a plaintext of any practical size. In the alternative algorithms, like Cramer-Shoup and PSEC, for a large plaintext, either the message expansion is proportional to its size or an additional security assumption is needed. Although some restrictions are posed on the public part of the key, we show how to easily find the needed parameters, and also suggest ways to make the public key as small as possible.
Revogação com Downgrade
Authors: Negrello Fábio , Wainer Jacques
Published: August 2022

Este artigo apresenta um modelo flexível de autorização que permite controlar de forma precisa a formação de cadeias de delegações, tanto através da limitação no comprimento tais cadeias, como atráves da definição de condições para aceitação de novas delegações. Direcionado a este modelo, é proposto um algoritmo eficiente de revogação com downgrade, que mantém os sujeitos com o maior conjunto possível de direitos, considerando-se as cadeias de suporte alternativas restantes após a revogação de delegações. É apresentado um algoritmo para aceitação, que verifica se há ao menos uma cadeia de suporte válida para cada nova delegação.

Authors: Ueda Eduardo Takeo , Terada Routo
Published: August 2022

Neste artigo analisamos uma das técnicas de criptanálise mais bem sucedidas contra o algoritmo RC6, o ataque χ2. Utilizamos este tipo de criptanálise como ataque de distinção e também como ataque de recuperação da chave. Apresentamos uma versão modificada do algoritmo RC6 que foi projetada através da introdução de uma função de troca em sua estrutura. Constatamos através de experimentos estatísticos que esta nova versão é mais forte contra a técnica de criptanálise χ2.
Reconhecimento de padrões de comportamento individual baseado no histórico de navegação em um Web Site
Authors: Carmo Luiz Fernando Rust da Costa , Costa Danielle
Published: August 2022

Este artigo investiga o uso do conceito de confiança para controle de acesso e autenticação de usuários em aplicações Web. A evolução da confiança é estabelecida através da avaliação do comportamento do usuário, e depende de fatores como: um ambiente Web apropriado à coleta e armazenamento de informações do comportamento do usuário, e a atribuição de uma medida de confiança a este comportamento. Para quantificar, e conseqüentemente, estabelecer uma medida de confiança, várias técnicas de reconhecimento de padrões de comportamento foram investigadas e avaliadas empiricamente através de um processo experimental.
Anonymous one-time broadcast using non-interactive dining cryptographer nets with applications to voting
Authors: van de Graaf Jeroen
Published: August 2022

All voting protocols proposed so far, with the exception of a few, have the property that the privacy of the ballot is only computational. In this paper we outline a new and conceptually simple approach allowing us to construct a protocol in which the privacy of the ballot is unconditional. Our basic idea is to modify the protocol of Fujioka, Okamoto and Ohta[10], which uses blind signatures so that the voter can obtain a valid ballot. However, instead of using a MIX net, we use a new broadcast protocol for anonymously publishing the vote, a non-interactive variation of the Dining Cryptographer Net.

Neste trabalho é apresentada uma abordagem alternativa, denominada SecBox, para proteção de arquivos de sistema e multimídia no interior de set-top boxes. Basicamente, o sistema usa uma combinação de algoritmos de criptografia e esteganografia, não explorados na área. Como resultado direto, a SecBox pode auxiliar na prevenção de ataques aos dispositivos de armazenamento e pirataria digital. O sistema tem funcionamento em set-top boxes com Linux que utilizam quaisquer sistemas de arquivos.
Uma Proposta de Marcação de Pacotes para Rastreamento Robusto a Ataques
Authors: Moreira Marcelo D. D. , Laufer Rafael P. , Velloso Pedro , Duarte Otto Carlos M. B.
Published: August 2022

Este artigo propõe uma nova estrutura de marcação de pacotes robusta a ataques a aplicações distribuídas como o rastreamento de pacotes IP. A estrutura de dados baseia-se no Filtro de Bloom, que permite representar de forma compacta um conjunto de elementos. O objetivo da proposta, denominada Filtro de Bloom Concatenado (FBC), é prover robustez à interferência do atacante e, com isto, garantir maior segurança na transferência da informação em um meio inseguro. A idéia chave da proposta é concatenar diversos subfiltros, cada qual admitindo somente um elemento. Resultados analíticos mostram que o filtro proposto é bem eficaz e que a probabilidade de sucesso do ataque proposto decresce exponencialmente com o tamanho de cada subfiltro. Não foi encontrada na literatura nenhuma proposta que provesse tal robustez sem a limitação de perda de informação legítima.
Avaliação de Proteção contra Ataques de Negação de Serviço Distribuídos (DDoS) utilizando Lista de IPs Confiáveis
Authors: Oliveira Luis , Aschoff Rafael , Lins Bruno , Feitosa Eduardo , Sadok Djamel
Published: August 2022

A severidade dos problemas causados por ataques DDoS e o aumento da freqüência e sofisticação dos mesmos têm contribuído para o surgimento de um grande número de mecanismos de defesa. Neste trabalho é proposto um sistema de detecção e prevenção de ataques DDoS baseado numa arquitetura modularizada. A idéia principal da solução consiste em manter uma tabela com o histórico de boas conexões já estabelecidas na rede, para que em situações de ataque essas sejam favorecidas com a maior parte da largura de banda disponível em detrimento de conexões desconhecidas e/ou de atacantes que serão limitadas por filtros. Os resultados dos testes demonstraram que a solução apresenta bom desempenho contra ataques DDoS massivos, grande escalabilidade e baixo consumo de recursos do sistema enquanto não prejudica o trafego legitimo.
Avaliação de Confiança Contextual em Grades Computacionais Multímodo usando Plataformas Seguras
Authors: Costa Ricardo de Barros , Carmo Luiz Fernando Rust da Costa
Published: August 2022

Esse artigo investiga o uso integrado de plataformas seguras (TPM), técnicas de virtualização, e mecanismos baseados em confiança, em uma grade computacional, visando à proteção das aplicações, e dos próprios recursos da grade. Para isso, definem-se quatro possíveis modos de operação para o nó de uma grade (multímodo), com níveis de proteção variando em função dos mecanismos de segurança requisitados. O Modo de operação de uma aplicação é selecionado conforme a confiança contextual apresentada pelo usuário no momento de sua submissão. Para o cálculo da confiança são considerados quatro diferentes fatores: forma de identificação, robustez da plataforma cliente, qualidade da comunicação e reputação do usuário. As simulações efetuadas fornecem subsídios quanto aos limiares de níveis de confiança que devem ser usados para a determinação do modo de operação, visando aperfeiçoar o desempenho da grade.
Extensões ao Modelo RBAC de Restrições para suportar Obrigações do UCONABC
Authors: Silva Edemilson S. , Santin Altair O. , Jamhour Edgard , Maziero Carlos A. , Toktar Emir
Published: August 2022

Este artigo apresenta uma proposta de extensão ao modelo Role-Based Access Control (RBAC) para suportar atividades que exigem mudanças nos atributos de autorização em tempo de execução. Tais atividades não podem ser divididas em subtarefas a serem executadas seqüencialmente e nem podem ser realizadas por um único papel. A abordagem apresentada permite a criação de papéis quorum, que só podem ser ativados numa sessão com o endosso de um quorum de outros papéis. Um protótipo mostra a viabilidade da proposta em um cenário de gerenciamento de redes. No caso, um conjunto pré-definido de papéis ativa o papel quorum para executar uma configuração na rede sem a participação do administrador da mesma.

Ongoing automation and the open access implementation of critical systems are increasing security vulnerability in automation and control networks employed in the electric power sector. This work is of the view that the integration between policy-based management and access control mechanisms is necessary to take us closer to a more effective solution for the combat against security threats. This paper introduces a modular architecture based on the XACML framework and applies this to automation and control networks used in the electric power industry. This security architecture is described and its components are individually analyzed and tested in a real power production environment. This paper also describes relevant encountered difficulties, provides results and new insights into access control when applied to industrial critical network infrastructures.
POLVO-IIDS: Um Sistema de Detecção de Intrusão Inteligente Baseado em Anomalias
Authors: Mafra Paulo M. , Fraga Joni da Silva , Moll Vinícius , Santin Altair Olivo
Published: August 2022

Os sistemas de detecção de intrusão (IDS) têm como atribuição a identificação de ataques e ameaças aos sistemas computacionais. Adicionalmente, os IDSs podem desempenhar funções de prevenção a intrusão (IPS), incluíndo-se ações pro-ativas às intrusões. Um problema recorrente destes sistemas de detecção de intrusão é a dificuldade de diferenciar ataques de acessos legítimos. Muitos sistemas utilizam assinaturas de ataques conhecidos, contudo não conseguem identificar variações destes ataques nem novos ataques. Este artigo apresenta um modelo de sistema de detecção de intrusão que classifica mensagens por análise comportamental como normal ou anômala. Para detecção de anomalias são utilizadas duas técnicas de inteligência artificial chamadas support vector machine (SVM) e redes neurais de Kohonen (KNN). O uso destas técnicas em conjunto visa melhorar a taxa de acerto do IDS desenvolvido, identificando ataques conhecidos ou novos em tempo real.

Published: August 2022

As linguagens de descrição de composição de Serviços Web tratam especificamente da definição da lógica dos processos de negócio e não dão suporte a especificação dos aspectos de segurança dos Serviços Web envolvidos. Este artigo define um modelo que, com o auxílio do padrão WS-Policy e das linguagens WS-BPEL e WS-CDL, promove a verificação preliminar da compatibilidade das políticas de qualidade de proteção dos participantes de um processo de negócio e constrói a política composta do processo.
