Role of zinc in inducing resistance in rice to whitebacked planthopper (Sogatella furcifera) under field conditions
Authors: Tripathy Seema , Rath Ladu Kishore
Published: November 2022

The study on influence of Zn applied in forms of fertilizer formulations was carried out against whitebacked planthopper (WBPH) [Sogatella furcifera (Horvath)] infesting rice under field conditions during kharif 2016, summer 2016-17 and kharif 2017 in the Central Research Farm, College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar. It was revealed that application of zinc to rice crop was instrumental in curbing the WBPH population. Basal application of Zn EDTA @ 40 kg/ha along with its foliar spray@ 0.8%, twice at 30 and 45 days after transplanting (DAT) (T6) was the best treatment in reducing the number of WBPH population over seasons as well as in increasing the grain yield. The next better treatment was T7 (ZnSO4 basal @ 25 kg/ha +Zn EDTA foliar spray @ 0.8% twice at 30 and 45 DAT) which also reduced the WBPH population substantially. From the entire study, it was inferred that reduction in WBPH population in various Zn supplementations as compared to control may be attributed to influence of Zn on rice plant physiology. Uptake of zinc definitely altered the nutritional status of rice plant as a result of which the population build up of WBPH on rice was minimized.

Published: November 2022

An experiment was conducted to quantify and evaluate bioactivity of phenolics from peel and callus extracts of sweet lime (Citrus medica). Cotyledon, epicotyl and hypocotyl-derived calli of sweet lime were obtained on solid MS medium supplemented with 2, 4-D and Kin. Cotyledon exhibited the best response on callus induction medium. Various extracts were prepared from peel and callus using different solvents, i.e. 50, 80 and 90% (v/v) of ethyl acetate, isopropyl alcohol, methanol and ethanol, employing maceration, orbital shaking, ultrasonic assisted and soxhlet extractions followed by estimation of total phenolic content (TPC) and total flavonoid content (TFC). Soxhlet extraction with 80% ethanol from peel was found to be the best combination as the yields of extracts; TPC and TFC were found to be the highest. Peel extract of sweet lime (80% ethanol, soxhlet) showed the highest antioxidant potential, i.e. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and antibacterial potential against Bacillus aryabhattai and Klebsiella sp. Thus, peel of sweet lime, being a potential source of phenolic compounds with antioxidant and antimicrobial properties, may be used as an ingredient for the preparation of functional foods.

Authors: Rani Jyoti , Rashmi Kumari , Sinha Sweta , Sahay Sanjay , Mandal S S , Singh Birender
Published: November 2022

A set of 24 maize inbred lines were analysed by using Rice SSR markers (40). Out of which, 14 SSR markers were found to be amplified and reproducible in which 10 markers showed polymorphism and rest showed monomorphic bands. A total of 32 polymorphic alleles were found. The average polymorphic information content (PIC) value was 0.28 with maximum 0.36 (RM552) and minimum 0.14 (RM216). By the use of Unweighted paired group method (UPGMA) for cluster analysis and formed four clusters in which genotype CML425 was found extremely diverse from rest of the genotypes. This represents its unique genetic structure from the rest genotypes. The overall result indicates that the genotypes present in these clusters have maximum genetic diversity that will help in classifying various genotypes in exact heterotic groups for future breeding programme. The study provided sufficient information about the genetic diversity of maize inbreds and that also identified common markers for rice and maize genetic studies that can be helpful for reducing cost effective measures for producing crop specific markers. In this way, identified clusters may be used for future breeding programme. This study also concluded that SSR marker can be taken as good complementing tool.

Published: November 2022

A field experiment was conducted on rice (Oryza sativa L.) during kharif season of 2017 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U P) to assess the nitrogen (N) use efficiency and performance of rice under different nitrogen management practice. Management practices included N levels with modified application through leaf colour chart (LCC) and chlorophyll meter (SPAD). The study shows that treatment T6 (LCC (50 kg N/ha) with basal N @50 kg/ha)gave highest yield and N-use efficiency which were comparable to T9 (SPAD (67 kg N/ha) with basal N @33 kg/ha). The total biological yield (grain + straw) of rice was significantly higher in T6 (114.4 q/ha) as compared to control (66.9 q/ha). The SPAD and LCC-treated plot showed higher N-use efficiency in rice over fixed-scheduling N treatments. Highest N content(1.88% (grain) and 0.76% (straw)) and uptake (128.14 kg/ha) was recorded in T6 treatmentin all stages (tillering, PI and harvest) which was comparable with T8 and T9 treatment.

Livelihood Diversity of Forcibly Displaced Rohingyas Encamped in Bangladesh
Authors: Hoque Mohammad Mainul , Yunus Mohammad
Published: November 2022

This paper assesses the livelihood strategies of the forcibly displaced Myanmar nationals encamped in Cox’s Bazar district of Bangladesh. Although the predominant source of livelihood of the encamped Rohingya households is supposed to be various sources of assistance and transfer receipts, almost 76 per cent of them report positive income from various sources, including farm activities, enterprises, labour market, remittance, and non-food transfers, despite restrictions on mobility and income generation through employment. While a few of the sources dampen income inequality, others exacerbate it. Similarly, while several factors facilitate participation in income generation both at the extensive and intensive margins, a few others appear to hinder the process. Both the diversity and the level of income appear to be higher for households in the old wave (arrived before 25 August 2017) compared to that in the new wave (arrived after 25 August 2017), possibly due to better integration and adaptation to the local environment and context. The encamped Rohingya households with supplementary earned income and receipts rather than exclusively depending on WFP assistance enjoy relatively better well-being, at least in terms of higher expenditure and dietary diversity. The evidence on the impact of earned income and receipts on household well-being indicators reinforces their appeal for the right to work.
Does Fuel Pricing Affect Males and Females Differently? Evidence from Kerosene Using Households in Rural Bangladesh
Authors: Chowdhury Tahreen Tahrima , Murshid K.A.S.
Published: November 2022

Energy sector reform, particularly the pricing of fuel and its gender-differentiated impacts, is rarely studied in the literature on energy and gender. This empirical study examines whether energy pricing has differential consequences for men and women with regard to kerosene oil use in rural Bangladesh. Specifically, the variables under focus are the duration of the study, duration of night-time leisure and time spent on income-generating activities. A household survey with 630 kerosene using rural households has been conducted in eight districts of Bangladesh. Apart from OLS estimation, we also use IV to address the endogeneity embedded in the model. The study finds that higher kerosene prices have a gender-differentiated effect on study duration, night-time leisure duration and time spent on income-generating activities in the context of household use of lighting fuel. Females are more adversely affected by higher kerosene prices in terms of study duration and night-time leisure hours. The effort to offset these losses by increasing effort on income-generating activities is less successful for women than men.
Multimorbidity among Women of Reproductive Age in Desertified and Degraded Districts of India
Authors: Manikandan A.D. , Unisa Sayeed , Praveenkumar M.P.
Published: November 2022

Multimorbidity or co-morbidity is defined as the co-occurrence of two or more chronic conditions in an individual. This paper analyses the prevalence of multimorbidity among women of reproductive age in backward districts of India. Multivariate linear regression is applied using the enter method to study factors independently associated with multimorbidity in women of reproductive age (15 and 49 years) in 75 desertified and degraded districts of India. Separate regressions are performed for women in both the rural and urban areas. The findings of the study reveal that the weighted prevalence of multimorbidity among reproductive women is 17.2 per cent. Further, regression analyses show that, among all explanatory variables, ageing and high income strongly affect multimorbidity among women aged between 15 and 49 years. However, the adverse effects of land degradation on multimorbidity could not be confirmed.
The Lived Dystopia of the Rohingya: Liminalisation, Demonisation, and Expulsion
Authors: Mozumder Mohammad Golam Nabi
Published: November 2022

The prospect and willingness of the Rohingyas to repatriate are, by and large, conditioned by their past experience of living in Myanmar. Discussions on repatriating the Rohingyas are likely to fail not because they are unwilling to return but mainly because of the lack of reasonable initiatives to address the deep-rooted animosity against the minority group prevalent in the country they had to flee. This paper analyses the findings of the 50 in-depth interviews of the refugees encamped in Cox’s Bazar. It presents ten instances of injustice, nine examples of forced payments, and systemic discrimination against the Rohingyas in Myanmar. Twenty-eight per cent of the respondents reported that at least one family member or relative was killed during the atrocities in 2017. The study finds that not all Buddhists participated in the attack against the Rohingyas; some reportedly helped the victims find safe shelter. The Rohingyas in Bangladesh suffer from an insufficient supply of relief during the last days of a relief distribution cycle. To survive, they take loans and seek illegal ways for finding employment outside the camp. While awaiting the perpetrators to be brought to justice, some Rohingyas remain optimistic about a peaceful return to their home country. And others are scared of even thinking of going back to the places where they witnessed both their homes and hopes burnt into ashes. Besides proposing two short-term measures— “burden-sharing” and “internal flight alternative”—this paper underscores the need for a novel approach in finding a durable solution to the problem.
VIOLÊNCIA POLICIAL COMO POLÍTICA PÚBLICA
Authors: Silva Monique Fonseca
Published: November 2022

O objetivo de estudar o caso da Arguição de Descumprimento de Preceito Fundamental (ADPF) 635 foi tratar a temática da violência policial como política pública. Se as operações policiais já eram um tema caro e que precisava ser enfrentado pela Corte Constitucional, com a pandemia da COVID-19, sua intervenção tornou-se extremamente necessária. As medidas sanitárias indicadas para o enfrentamento da pandemia incluíam distanciamento social que resultou em menos circulação de pessoas e, assim sendo, os agentes de segurança sentiram-se mais confortáveis para cometer abusos. Verificou-se nesta investigação que a política de segurança, em geral, é a ferramenta atual de manutenção de racismo e desigualdades, a partir da militarização da vida cotidiana de pessoas negras e pobres. A análise deste estudo evidenciou o basilar papel do racismo para permitir ao Estado a execução do biopoder e, diante da constatação das constantes violações de direitos humanos por parte do Estado brasileiro, verificou-se a prática da necropolítica no país.
A FUNÇÃO DEMOCRÁTICA DO INQUÉRITO POLICIAL NO PROCESSO PENAL
Authors: Drummond Lucas Ruas
Published: November 2022

O inquérito policial, espécie do gênero investigação preliminar, necessita de uma nova visão, através de um filtro democrático e atual. Sua verdadeira função dentro do processo penal, vez por outra, é flexibilizada e ampliada para além de sua estrutura e natureza jurídica, ensejando problemas de ordem prática e teórica. Neste sentido, o presente trabalho buscará resgatar o núcleo das investigações preliminares, dando ênfase ao inquérito policial, dada sua predominância sobre outras espécies de investigações preliminares, sem, contudo, excluir das observações as demais formas de investigação. Ao se adotar uma postura crítica frente às indevidas e reiteradas distorções do procedimento preparatório, sem pretensão de esgotar o tema, se buscará (re)afirmar as funções e limites do inquérito policial, para que o procedimento possa se prestar ao seu importante dever de coletar a justa causa para a formação da “opinio delicti” do acusador e a propositura da ação penal, sem, contudo, se imiscuir na decisão judicial.
DE LA "IGUALDAD FORMAL" A LA "IDENTIDAD"
Authors: Femenías María Luisa
Published: November 2022

La trama política que va del multiculturalismo a la democracia es tensa y compleja. Para algunos teóricos, las demandas multiculturales mantienen las estructuras tradicionales discriminatorias; para otros, supone un reconocimiento de las diferencias y por tanto la perspectiva idónea para hacer visibles las operaciones de dominio que las culturas hegemónicas implementan sobre las culturas minoritarias. Esta tensión merece revisarse tomando en cuenta la noción de interseccionalidad, y la situación de las mujeres, porque en los reclamos de identidad cultural llevan la peor parte. Además, la democracia debe hacerse cargo de los reclamos multiculturales positivos. Para ello la mejor opción es la democracia deliberativa que, en la versión de Vidiella, se basa en una igualdad sustantiva y es sensible a las cuestiones feministas y de género, siendo compatible además con un paradigma universalista de derechos.
A POSSIBILIDADE DE CARACTERIZAÇÃO DA IMPORTUNAÇÃO SEXUAL CASO O CRIME DE ASSÉDIO SEXUAL SEJA EXAURIDO
Authors: Rocha Lorraine Gonçalves Almeida
Published: November 2022

O presente artigo tem como objetivo verificar a possibilidade da incidência do crime de importunação sexual nos casos em que o agente, sendo chefe da vítima, não apenas constrangê- la, mas também obtiver a vantagem sexual almejada. O mero constrangimento e a prática do ato em si pressupõem lesões diferentes ao mesmo bem jurídico tutelado, qual seja a dignidade sexual, razão pela qual subsiste a necessidade de se realizar essa verificação. O tipo penal da importunação sexual prevê uma sanção mais grave do que a pena estabelecida para o crime de assédio e, por isso, o artigo pretende fazer crer mais adequada sua incidência à uma conduta que produz consequências mais nefastas. A pesquisa terá como foco não só a intencionalidade do agente, que é sempre o principal foco do Direito Penal, mas também a teoria das consequências, a qual coloca a vítima em atenção, levando em consideração os efeitos da ação para ela. Para tanto, analisará as mudanças ocasionadas na legislação e na jurisprudência pela criminalização da importunação sexual, que antes era tida apenas como uma contravenção penal, e o que a doutrina diz a respeito da possibilidade da aplicação do caráter subsidiário ao crime de assédio sexual. Também verificará as consequências sofridas pelas vítimas de violência sexual e a etiomologia da palavra importunação, bem como estudará um caso que foi julgado no Superior Tribunal de Justiça e que corrobora a incidência do crime de importunação sexual no caso de exaurimento do assédio sexual, traçando uma comparação entre o entendimento doutrinário e jurisprudencial acerca do assunto.
O DEBATE HABERMAS E PUTNAM
Authors: Rodrigues Sérgio Murilo
Published: November 2022

Valores e normas podem igualmente reivindicar uma validez universal fundada na racionalidade para questões relacionadas com a justiça? O filósofo norte-americano Hilary Putnam (1926-2016) considera que a dicotomia entre fatos e valores é uma falsa dicotomia e, uma vez superada, seria possível validar de forma racional e universal os juízos de valores. Já o filósofo alemão Jürgen Habermas (1929) defende que somente as normas podem ter validez racional e universal, pois os valores estão de tal maneira comprometidos com determinados modos de vida, contextos comunitários e culturais, que a universalização deles se torna uma tarefa pouco produtiva, para não dizer impossível. Este artigo abordará as contribuições do debate entre Habermas e Putnam sobre o problema dos valores e das normas na ética e suas implicações para as questões de justiça.

Recently, several research works have been conducted on processing of preference queries over data streams. Preference queries are useful for many application domains where users aim to find out the closest data items to their wishes. This paper presents a new operator for the StreamPref language that can be employed to obtain the top-k data stream sequences according to temporal conditional preferences. Temporal conditional preferences can allow a user to express how past instants of a data stream may influence his preferences at a present instant. In order to evaluate this new operator, two new algorithm strategies are also presented. The extensive set of experiments performed show that the incremental strategy presents a superior performance in all experimental settings. Moreover, the results achieved show that the proposed operator has a superior performance when compared to the equivalent operation in CQL.

A geometrical pattern is a set of points with all pairwise distances (or, more generally, relative distances) specified. Finding matches to such patterns has applications to spatial data in seismic, astronomical, and transportation contexts. Finding geometric patterns is a challenging problem as the potential number of sets of elements that compose shapes is exponentially large in the size of the dataset and the pattern. In this paper, we propose algorithms to find patterns in large data applications. Our methods combine quadtrees, matrix multiplication, and bucket join processing to discover sets of points that match a geometric pattern within some additive factor on the pairwise distances. Our distributed experiments show that the choice of composition algorithm (matrix multiplication or nested loops) depends on the freedom introduced in the query geometry through the distance additive factor. Three clearly identified blocks of threshold values guide the choice of the best composition algorithm.

A popularidade do desenvolvimento global de software Open Source aumenta a necessidade de busca por especialistas capazes de auxiliar outros desenvolvedores na resolução de tarefas complexas. O desafio é: dada uma tarefa, como identificar o melhor especialista (ou um conjunto de especialistas) para executá-la? Este problema é chamado de localização de especialistas. Algumas das dificuldades desta pesquisa são o grande volume de dados produzido, a ausência de maiores detalhes técnicos dos envolvidos e os diferentes níveis de colaboração. O objetivo deste trabalho é detectar especialistas e identificar grupos com participantes experientes em determinados tópicos em um fórum Q&A. Para tal, o fórum StackOverflow foi modelado como uma rede complexa. O método apresentado é composto pela detecção de comunidades sobrepostas através do algoritmo NetSCAN. Através de uma análise temporal foram reveladas as aptidões dos desenvolvedores, mostrando também uma tendência de mudança de seus interesses. A avaliação do método foi feita através de uma análise de viabilidade, comparando as notas das respostas dos especialistas (apontados pelo método proposto) com as notas das respostas dos usuários comuns.

In-memory databases, just as hard drive ones, may offer hundreds of customizable settings, making the task of system tuning overwhelming for a database administrator. Even worse, the number of parameters continues to grow over the years and they can affect performance in a not intuitive manner. Models that capture their behavior can assist automatic tuning mechanisms to obtain optimal performance. In this work, we propose a learning-based approach to select the most meaningful parameters and generate a performance model based on both the workload and the database configurations. Experimental results confirm that our approach can create accurate performance models using only a reduced set of selected parameters.
Database Tuning with Partial Indexes

Published: November 2022

Database tuning usually involves indexes, materialized views, partitioning, query rewriting and other techniques. One strategy that presents good results for performance improvements is the use of partial indexes. However, partial indexes have not been used for database tuning in the past. This is because the search space for partial indexes is exponential in the number of attributes and tuples of the table. In this paper, we address this problem by proposing an optimized strategy to select partial indexes. The optimization relies on reducing the amount of logic reads. We explain how to select the indexable attributes and their corresponding restrictions through a formal procedure. We implement our strategy to illustrate the benefits of partial indexes for tuning issues. Results are promising.

Diferentes protocolos de controle de concorrência impactam o desempenho do banco de dados, dependendo do perfil da carga de trabalho. Sem conhecimento prévio desta carga e suas mudanças, a decisão na escolha de um protocolo se torna desafiadora. Para tanto, criamos o FLEXMVCC, que integra dois protocolos de controle de concorrência multi-versão compatíveis, um otimista e um pessimista, capaz de se adaptar conforme as mudanças na carga de trabalho. Experimentos preliminares mostram que a troca entre protocolos é viável e representa um ganho de desempenho em relação aos protocolos estáticos.

Os workflows emergiram como uma abstração básica para estruturar experimentos de análise de dados no atual cenário de DISC (Data Intensive Scalable Computing). Em muitas situações, estes workflows são intensivos, seja computacionalmente ou em relação à manipulação de dados, exigindo a execução em ambientes de processamento de alto desempenho. Entretanto, paralelizar a execução de workflows comumente requer programação trabalhosa, de modo ad hoc e em baixo nível de abstração, o que torna difícil a exploração das oportunidades de otimização. Algumas abordagens algébricas foram desenvolvidas visando mitigar tal limitação. Este trabalho caminha na direção de convergir a álgebra de workflows com o processamento de consultas relacionais.

A grande quantidade de dados de RDF existente nos dias de hoje requer que as consultas SPARQL sejam processadas de forma eficiente. Uma possível abordagem para atingir tal objetivo e o armazenamento dos dados em uma base relacional de entidades, que explora a similaridade das estruturas para a horizontalização das triplas. Neste artigo, é proposto um método para a tradução de consultas SPARQL para SQL para ser processada sobre uma base relacional de entidades. Os experimentos realizados mostram que as consultas traduzidas e executadas sobre esta base obtiveram um ganho de desempenho de aproximadamente 250% em relação à consulta sobre uma tabela de triplas.

Background: The cell membrane acts as a filter, allowing ions to enter and leave the cell. Ionic channels are responsible for passing ions. This task is the responsibility of the ion channel gates, and ion transfer generates the action potential. Potassium channels play a prominent role in gastrointestinal smooth muscle cells and slow-wave production. Potassium channels are involved in acid secretion and gastric contraction. Gastric functional problems such as reflux disease and motility disorder are classified as electrophysiological disorders. Objectives: This study aimed to investigate the effect of potassium channel gates on the electrophysiology of the human gastric smooth muscle cells. Methods: Three states were considered for the potassium channels gate (Including physiological state, 50% blockage, and 90% blockage) to investigate the effect of the status of the gates, and a slow-wave diagram was obtained in these three states. Then, the value and the time of action potential were compared at five indicator points (initial potential, maximum spike potential, minimum valley potential, maximum plateau potential, and resting potential) in slow-wave. Results: The results showed that the maximum effect of the activation parameter of the potassium channel gate (τd,Kni) was in 90% blockage compared to the physiological state, so that the maximum spike potential decreases by 2.43%. Also, a 90% blockage in the fast potassium channel gate inactivation parameter (τf,Kfi) increased the maximum spike potential by 12.6% compared to the physiological state, while the minimum valley potential increased by 3%. In addition, the τf,Kfi parameter reduced the time of occurrence of the maximum plateau potential by 7.9%. Conclusions: Potassium channels affect the slow-wave of the human gastric smooth muscle cell in spike, valley, and plateau phases. Using this method and blocking ion channels by pharmacological agents, the effect of ions in different phases of the slow-wave can be investigated. Also, it can help improve the contractile and motility disorders of the smooth muscles of the gastrointestinal tract.
