Published: May 2021

The healthcare system is a vital element for any community, as it extremely affects the socio-economic development of any country. The current study aims to assess the performance of the healthcare systems of the countries above fifty million citizens in facing the spread of the COVID-19 pandemic since late December 2019. For this purpose, seven scenarios were adopted via the DEA methodology with six variables, which are the number of medical practitioners (doctors and nurses), hospital beds, Conducted Covid-19 tests, affected cases, recovered cases, and death cases. To shed light on the relative efficiency of drivers, the Tobit analysis was used. Besides, the study carried out various statistical tests for the DEA models' findings to validate the choice of the variables and the obtained scores. The DEA results reveal that less than half of the considered countries are relatively efficient. Moreover, the Tobit regression analysis showed that the main impact on the efficiency scores was due to the number of affected and recovered cases. Finally, the results of the tests of Spearman, Mann-Whitney U, and Kruskal-Wallis H indicate the internal validity and robustness of the chosen DEA models. The current study findings raise important implications, which can be helpful for decision makers regarding continuous improvement of performance, in which the findings assert the importance of achieving the best practices regarding relative efficiency through the linkage between the healthcare systems’ resources, and the needed outputs.

Published: May 2021

Este estudo teve como objetivo sintetizar as evidências sobre mo-tivações, pensamentos e experiências de adolescentes brasileiros com ideação suicida. A busca foi realizada em MEDLINE, EMBA-SE, LILACS, PsycINFO, Google Scholar e Google. A seleção de ar-tigos, a extração de dados e a avaliação da qualidade metodoló-gica foram realizadas por dois pesquisadores independentes. De 3.496 artigos identificados, quatro foram incluídos. As principais motivações para a ideação suicida foram a fragilidade dos víncu-los, quadro depressivo e carência afetiva. Os sentimentos predo-minantes foram solidão, tristeza, desamparo e desesperança. Os pensamentos relacionados com a crença de estar só no mundo e de não enxergar solução para seus sofrimentos e conflitos foram relatados. A ideação suicida pode ser um fenômeno importante entre adolescentes brasileiros, requerendo a atenção da socieda-de, especialmente da academia e governo, para ampliar a base de evidências e a discussão sobre políticas públicas preventivas ao suicídio.

Published: May 2021

Acumuladores são pessoas reconhecidas por reunir excessiva-mente objetos ou animais domésticos de forma desordenada e de-sorganizada. Geralmente vivem em locais com déficit de higiene, de autocuidado do corpo e do ambiente habitacional interferindo na sua qualidade de vida, de sua família e da comunidade onde vive. Na comunidade há potencial de risco para ocorrência de algu-mas endemias transmitidas por vetores, hospedeiros, incômodos e peçonhentos. O objetivo do estudo foi realizar uma revisão de evidências na literatura sobre acumuladores de materiais/objetos (síndrome de Diógenes) e de animais domésticos (síndrome de Noé) e seu impacto para a saúde com foco nas endemias. Uma pergunta estruturada orientou o método, com levantamento de termos em três idiomas, nas bases de dados de PubMed, Em-base, Cochrane, Web of Science, Portal Regional da BVS, Google Acadêmico, além de literatura cinzenta. Dezesseis documentos compuseram a análise, apontando a necessidade de um cuidado multiprofissional para o tratamento desses pacientes. Com essa revisão esperamos contribuir com o melhor entendimento dos pro-blemas dos acumuladores no que tange ao controle necessário para evitar endemias nos diversos níveis de atenção à saúde, com perspectiva a traçar um fluxo efetivo de atenção multiprofissional.

Advocacy e ativismo não são palavras intercambiáveis, mas no Brasil estão sendo usadas como sinônimos. Com foco na Reduçãode Danos, a fim de mostrar sua trajetória no Brasil e no mundo, o artigo abrange a história, o conceito e as políticas públicas sobredrogas. Falar sobre Redução de Danos refere-se a um Brasil que há mais de trinta anos aprendeu com a epidemia de aids traba-lhar com o diverso, construir parcerias e, assim, criar um tripé: sociedade civil, governo e instituições internacionais. Evidenciam-setambém contribuições e obstáculos impostos pela ONU, além dos esforços da sociedade civil para ensinar o que é cuidar e oferecereducação em drogas. As convenções da ONU sobre drogas e outras possibilidades de entender seus significados encobertos. Opapel da sociedade civil é destacado através de um exemplo de como ser um ativista internacional.
Conceito de redução de danos em políticas públicas relacionadas a drogas
Authors: De Melo Ribeiro Maurides , Bellini Júnior Antonio Carlos
Published: May 2021

O consumo de substâncias psicoativas é hábito milenar, mas desde o século XIX, se observa um movimento proibicionista, que tem papel hegemônico na questão das drogas e dita um controle social usando ferramental penal. A questão das drogas, sob um viés bélico e criminalizante, não traz efeito positivo esperado: a erradicação ou diminuição do uso de drogas; e, ao contrário, traz malefícios como a marginalização do usuário, o cerceamento do seu direito à saúde e de poder escolher pela aquisição de drogas de melhor qualidade. A marginalização impacta, ainda, em seletividade penal, onde, na sua maioria, homens, jovens e negros, são parte de altos índices de encarceramento em razão de crimes relacionados a delitos de drogas. Ainda se verificam relações entre o fenômeno da violência e sua articulação com as drogas. Como política alternativa ao probicionismo, a Redução de Danos leva em consideração a complexidade do fenômeno e a multiplicidade de variáveis, a individualização do risco na cena do uso de drogas. Tal política tem o direito humanitário como princípio basilar e considera a vulnerabilidade como critério de eleição para a adoção de ações de Redução de Danos.

Psicanálise e redução de danos
Authors: Cavallari Celi , Reale Diva
Published: May 2021

Em São Paulo, os projetos baseados nos princípios de Redução de Danos tiveram início na capital, em 1988, com a pesquisa e intervenção do Projeto Bleach do Centro de Referência e Tratamento de DST/Aids e, com o Projeto de distribuição de seringas e agulhas em Santos, em 1989. A presença de duas psicanalistas neste projeto paulistano pioneiro e, posteriormente, entre 1991 e 1994 no Projeto Prevenção ao Uso Indevido de Drogas e Aids constitui uma rara aproximação, na Saúde Pública, de campos teórico e práticos de caminhos independentes: a Psicanálise e a Redução de Danos. Investigar como esta aproximação pode amplificar as potências destas práticas é um dos principais objetivos deste artigo. Os projetos destacados trazem o compromisso ético com o incremento da autonomia de pessoas que sofreram prejuízos decorrentes de suas complexas condições de vulnerabilidade, amplificadas pelo abuso ou dependência de álcool e outras drogas e justificam a busca de opções, para além da clínica, que possam ganhar potência no cuidado singular e coletivo.

Trasplante en la enfermedad hepática por alcohol
Authors: Neira-Moreno Jessica Paola
Published: May 2021

La enfermedad hepática por alcohol es una de las enfermedades hepáticas más prevalentes en todo el mundo, y una de las principales causas de morbilidad y mortalidad. La enfermedad puede progresar desde estadios leves, como el hígado graso alcohólico, hasta condiciones severas que incluyen cirrosis y, en algunos casos, carcinoma hepatocelular. A su vez, la esteatohepatitis alcohólica grave es una presentación aguda de la enfermedad hepática por alcohol asociada con una alta mortalidad. A pesar del tratamiento, entre el 30% y el 50% de los pacientes con hepatitis alcohólica grave finalmente fallecen. En los casos de enfermedad avanzada, el trasplante hepático puede ser la única opción para la supervivencia del paciente. El trasplante por hepatitis alcohólica ha sido un tema controvertido, y algunos países todavía aplican la “regla de los 6 meses”, en la que se requiere este tiempo de abstinencia de alcohol antes de la cirugía. Estudios recientes recomiendan el trasplante de hígado en casos de hepatitis alcohólica grave que no responden a las terapias médicas, incluso sin el período de abstinencia requerido, ya que la mayoría de estos pacientes fallecen antes de 6 meses. Se requieren más estudios para apoyar la selección de los pacientes idóneos para trasplante hepático con un periodo de abstinencia menor de 6 meses. La prevención y el tratamiento de la enfermedad hepática alcohólica debe ser integral, con un abordaje multidisciplinario que incluya el manejo de la dependencia al consumo de alcohol, al igual que el manejo farmacológico o quirúrgico, de acuerdo con la necesidad de cada paciente.
Racism and Shaw
Authors: Dukore Bernard F.
Published: May 2021

For more than half a century, Shaw denounced racism and its counterpart, anti-Semitism, as well as the very idea of White supremacy, especially as they have been manifested in England and the British Empire (Egypt, India, South Africa, Australia, and Canada) as well as the United States and Nazi Germany. He related them to each other and to caste, social classes, and capitalism. This article surveys Shaw's dramatic and nondramatic works, including prefaces, interviews, articles, and his novella The Black Girl in Search of God, to provide an overview of Shaw's views on racism (including his solution to this social evil) and to argue that his perspectives remain relevant to twenty-first-century struggles against it.
Bernard Shaw's Interior Authors
Authors: Lenker Lagretta Tallent
Published: May 2021

This study serves as a prequel to my article “Shaw's Interior Authors: Censored and Modern,” which explores Shaw's use of characters who write in his plays and who experience some form of censorship that resembles the experiences of their creator. Interestingly, characters in the early works of Shaw, his five novels, also feel the sting of censorship, albeit in differing degrees from those in his dramas. Because Shaw's works, both plays and novels, that were suppressed often feature harsh indictments of established society, they become, in effect, proto-modern, as he attacks class, gender, and religious norms of his day.
Ding Xilin's Chinese Translation of The Man of Destiny
Authors: Li Kay
Published: May 2021

This article examines Ding Xilin's (丁西林) (1893–1974) Chinese translation of The Man of Destiny by making use of artificial intelligence and machine learning functionalities on IBM Cloud Computing Platforms to decipher Ding's cultural translation. While an untrained model of IBM Natural Language Understanding reveals Ding's using the translation to criticize imperialism, a trained machine learning model using IBM Watson Knowledge Studio shows the qualities of the Shavian Great Man. The IBM artificial intelligence and machine learning platforms, drawing attention to words and the semantic relations between them, uncover a subtle relationship between Ding Xilin's Chinese translation and the personality cult around China's Great Man, Mao Zedong (1893–1976), around the time of Ding's translation. The artificial intelligence platforms show that there may be subtle connections between Shaw's play and the most dominant figure in China at the time of the translation.
Victorian Masculinity and Mrs Warren's Profession
Authors: Park Jihay
Published: May 2021

This article focuses on the emergence of a new professional society in turn-of-the-century England and explores how Victorian masculinity is challenged by prostitution in George Bernard Shaw's play Mrs Warren's Profession (1893). Mrs Warren undermines Victorian masculinity by subverting the professional ideal undergirding late Victorian society. Mrs Warren challenges the Victorian acceptance of the Protestant notion of work as “duty” and alleges how work is deeply related with economic necessity. Also, Mrs Warren debunks the Victorian acceptance of the Christian notion of body and work and claims how work becomes a practice of self-formation via self-distancing not self-discipline.
Representing the moraic nasal in Japanese: evidence from Tōkyō, Ōsaka and Kagoshima
Authors: Youngberg Connor
Published: May 2021

This article reconsiders the nature and representation of the moraic nasal  in Japanese dialects, which is largely assumed to be a consonantal mora (Ito 1987, Vance 2008, Labrune 2008) or a variable segment (Yoshida S. 1996, 2003; Yoshida Y. 1999). I examine phonological processes and phonetic descriptions of the Tōkyō, Ōsaka and Kagoshima varieties of Japanese and show that previous representations do not capture all of the facts. I propose that N is best represented variously as a nasal consonant, a syllabic nasal or a nasal vowel depending on the dialect. I frame this account within the theory of Strict CV (Lowenstamm 1996) and I present new representations for N, taking into account segmental and prosodic behaviour of this segment. The overarching contribution is an analysis where the tonal status of N in Japanese dialects is directly derived from the status of nuclear positions that N is associated to or adjacent to, without reference to feature sensitive rules.
Critical Discourse Analysis of Iran-China Relations Through Football Headlines
Authors: Singh Rajdeep
Published: May 2021

Iran and China are getting closer day by day, from economic to political to social relations. Since media plays a significant role in shaping norms, social relations, and values in society, it is not a neutral medium to propagate information only. Social and political elites, as well as political fractions, use media to shape public opinion with the least cost. Therefore, this paper attempts to answer the question as to which ideologies, social and political thoughts Iranian football headline-writers attempt to convey to the wider public in Iran. To answer this question the main hypothesis of the paper posits that Iranian political and social elites are conveying a much more economic dimension of China, downplaying the political dimension of China, including the mounting political oppression inside China and Hong Kong, and the dramatic situation of Chinese Muslims. This paper approaches the abovementioned question under the framework of critical discourse analysis proposed by Norman Fairclough (1989). With regards to the methodology of the paper, a qualitative approach has been adopted, availing itself of different headlines of Iranian sport. Findings of the paper indicate that elites in Iran are proposing to the public a much rosier image of china due to closer political and economic ties between the two countries.
Continuous erector spinae plane block at lumbar level for relief of severe pain due to hip fracture: case series
Authors: Tovar-Gutiérrez Alejandro , Camelo-Rincón Julio Ernesto , Vásquez-Gómez Óscar Iván , Cadavid-Puentes Adriana Margarita
Published: May 2021

Introduction: Hip fracture pain is frequently acute and disabling and increases perioperative complications in the patient; hence it requires a multimodal analgesia approach. This case series describes the continuous erector spinae plane block at the lumbar level for hip fracture analgesia.

Methods: A search was conducted of patients with hip fracture referred to the pain service of Hospital Universitario San Vicente Fundación (HUSVF) from August 2019 to March 2020, who had undergone continuous erector spinae plane block as part of their analgesic regimen.

Results: A total of 6 patients, 4 females and 2 males with an average age of 75 years were identified. A reduction in pain intensity from acute to mild or absent was observed in every case, up to 24 hours after the initial injection. 66 % experienced a relapse of severe pain after 24 hours and 2 patients the catheter functionality failed after 24 hours. One patient underwent dermatome pinprick assessment.

Conclusions: The continuous erector spinae plane block with a single injection provided analgesic efficacy similar to other single injection peripheral blocks, although continuous analgesia for more than 24 hours was not achieved. Some variations in the block technique described may improve the analgesic effectiveness in patients with hip fracture pain.
Juan Evangelista Manrique, the true pioneer of spinal anesthesia in Colombia
Authors: Herrera Pedro José , Aguirre Serrano Herley
Published: May 2021

Several findings paved the way to the use of the spinal approach for anesthesia. Information about the originators and dates of their discoveries is controversial. According to personal communications, doctors Juan Bautista Montoya y Flórez, in Medellín, and Lisandro Leyva, in Bogotá, in 1904 and 1905 respectively, would appear to be the pioneers of spinal anesthesia in Colombia. Pioneering cases of this procedure carried out in 1901 by doctor Juan Evangelista Manrique and which continued to be performed by his colleagues and assistants of the medical community at the time are documented in the Corporis Fabrica dissertation collection of the National University of Colombia.

Introduction: Post-anesthetic complications, particularly respiratory complications, continue to be a source of concern due to their high frequency, particularly in pediatrics.
Objective: To describe the incidence of respiratory complications in the post-anesthesia care unit of an intermediate complexity center during a six-month period, and to explore the variables associated with major respiratory complications.
Materials and Methods: Retrospective cohort study based on clinical record reviews. The records of the post-anesthesia care unit of an intermediate complexity pediatric institution located in Medellin, Colombia, were reviewed. This center uses a nursing-based care model that includes patient extubation in the post-anesthesia care unit.
Results: The records of 1181 patients were analyzed. The cumulative incidences of major complications were bronchospasm 1.44%, laryngospasm 0.68% and respiratory depression 0.59%. There were no cases of cardiac arrest or acute pulmonary edema. A history of respiratory infection less than 15 days before the procedure, rhinitis and female sex were associated with major respiratory complications.
Conclusions: A low frequency of respiratory complications was found during care provided by nursing staff trained in anesthesia recovery and pediatric airway in the post-anesthesia care unit.

O RouteWatcher integra múltiplas fontes de dados em uma interface Web que permite pesquisadores e operadores identificarem e analisarem anomalias de roteamento.
A Implementação de um Protocolo Criptográﬁco para Geração Distribuída de Credenciais no Sistema CIVIS
Authors: De Sá Matheus , Araújo Roberto
Published: May 2021

O sistema para eleições via Internet CIVIS é baseado em um protocolo criptográﬁco que possibilita resistência à ataques coercivos, e para tal utiliza a ideia de credenciais. Uma credencial é formada por um conjunto de bits que deve ser gerado por um conjunto de autoridades eleitorais e entregue a cada votante em sigilo. Do contrário, o protocolo não garante resistência à ataques coercivos. Na versão atual do sistema CIVIS, entretanto, cada credencial é gerada porúnica autoridade eleitoral. Como consequência, o sistema depende que essa autoridade seja conﬁável para garantir a geração segura da credencial. Nesse contexto, este trabalho apresenta uma implementação de um protocolo para a geração distribuída de credencias a ﬁm de tornar a geração de credenciais mais segura no sistema.

Authors: Maqbool Mudasir , Dugassa Dinka , Fekadu Ginenus
Published: May 2021

Background: Epilepsy is a disorder that affects 1% of the global population. It is the second most common serious neurologic disorder after stroke, affecting humans. Since antiepileptic drugs have a narrow therapeutic index and their adverse effects can affect any organ, their widespread use has significant safety implications. Objectives: The study assessed adverse drug reactions (ADRs) using antiepileptic drugs in the Department of Neurology at a Tertiary Care Hospital, Srinagar, Jammu & Kashmir, India. Methods: This prospective observational study was conducted in the Department of Neurology of a Tertiary Care Hospital, Srinagar, Jammu & Kashmir, India, for eight months. It was a spontaneous reporting of ADRs by practicing physicians in the outpatient and inpatient settings that were included in the study. Results: Of the 3,300 patients who were on the anti-epileptic drug (AED), 92 (3.07%) had AED-related ADRs. A total of 18 cases were reported in the inpatient department and 74 cases in the outpatient setting. The most common ADRs were loss of appetite (34.78%), skin rashes (17.39%), and gum hypertrophy (9.78%). Of 80 ADRs, 42.5% were related to valproate, followed by phenytoin, carbamazepine, and levetiracetam. The suspected drug was changed in 22 patients with ADRs. Conclusions: For the early diagnosis and avoidance of ADRs, the frequent follow-up of patients on AEDs is needed to improve patient compliance with drug therapy and provide better drug therapy for avoiding associated morbidity and mortality.

Dyrosauridae is a clade of neosuchian crocodyliforms that diversified in terrestrial and aquatic environments across the Cretaceous-Paleogene transition. The postcranial anatomy of dyrosaurids has long been overlooked, obscuring both their disparity and their locomotive adaptations. Here we thoroughly describe of the postcranial remains of an unusually small dyrosaurid,Cerrejonisuchus improcerus, from the middle-late Paleocene Cerrejón Formation of Colombia, and we provide a wealth of new data concerning the postcranial anatomy of the key dyrosaurids:Congosaurus bequaertiandHyposaurus rogersii. We identify a series of postcranial autapomorphies inCerrejonisuchus improcerus(an elliptic-shaped odontoid laterally wide, a ulna possessing a double concavity, a fibula bearing a widely flattened proximal end, a pubis showing a large non-triangular distal surface) as well as functionally-important traits such as a relatively long ulna (85% of the humerus’ length), short forelimb (83% of hindlimb’s length), or thoracic vertebra bearing comparatively large lateral process (with widened parapophysis and diapophysis) along with strongly arched thoracic ribs allowing a more sturdy and cylindrical rib cage. These indicate a more terrestrial lifestyle forCerrejonisuchuscompared to the derived members of the clade. We also built a dataset of 187 traits on 27 taxa, that extensively samples the cranial and postcranial architectures of exemplar crocodyliforms. We analyze these data in via Principal Coordinate Analysis (PCoA) to visualize the postcranial morphospace occupation of Dyrosauridae, Thalattosuchia, and Crocodylia. Our data reveal the existence of a distinctive postcranial anatomy for Dyrosauridae that is markedly distinct from that of crocodylians. As a result, modern crocodylians are probably not good functional analog for extinct crocodyliformes. Postcranial data should also be more widely used in phylogenetic and disparity analyses of Crocodyliformes.

Phyllodes tumour is a rare tumour of the breast constituting less than 1% of all breast tumours. Malignant Phyllodes Tumour (MPT) accounts for only 10-30% of all phyllodes tumours. Heterologous sarcomatous differentiation in a MPT is an infrequent phenomenon, with the cases reported showing differentiation mostly towards liposarcoma, fibrosarcoma, angiosarcoma, osteosarcoma, or chondrosarcoma. MPTs with rhabdomyosarcomatous differentiation are scarcely seen with only three confirmed cases documented till date to the best of the knowledge after a thorough search of literature. Here, authors present a case of 45-year-old female who presented with a well-defined rapidly growing lump in the right breast for last one year. A core needle biopsy performed showed a sarcomatous picture on histology. Complete excision was subsequently done. On microscopy, most of the areas showed fibrosarcomatous changes with frequent mitoses. Some of the foci showed large pleomorphic cells in diffuse sheets that were polygonal with densely abundant eosinophilic cytoplasm and vesicular nucleus with prominent nucleoli (rhabdomyoblasts). Myogenin was diffusely positive on Immunohistochemistry (IHC). A diagnosis of MPT with rhabdomyosarcomatous differentiation was made. This case is reported here for its unusual presentation and to make pathologists aware of this rare heterologous differentiation of MPT.

Clear Cell Sarcoma of Kidney (CCSK) is a highly malignant renal tumour. The mean age of diagnosis is between 12-36 months. Due to heterogeneous histological appearance and age group affection similar to wilms tumour, it often leads to misdiagnosis. It has a tendency to metastasise distantly to bone and its therapeutic response differs from other childhood kidney tumours. So use of Immunohistochemical (IHC) markers becomes essential in many cases in differentiating CCSK from other paediatric renal neoplasms. It is extremely rare in adults, till now only 26 adult cases have been reported in the medical literature. Here, the case of a 49-year-old male presenting with haematuria and pedal oedema is reported. On radiological examination, he had a large left renal mass with tumour extension to Left Renal Vein (LRV) and Inferior Vena Cava (IVC) as thrombi. Histology and Immunohistochemistry (IHC) study revealed CCSK ruling the other differentials. This case is presented for its rarity in adult patients, unusual clinical feature of widespread vascular invasion rather than bone metastasis, simulating Renal Cell Carcinoma (RCC) and aggressive clinical behaviour. The diagnostic challenges faced by pathologist and clinicians further necessitate the proper diagnosis of the tumour for better management of such cases.

The objective of the present study was to evaluate some physicochemical and some antinutritional factors characteristics of sprouted seeds of white bean (Phaseolus vulgaris L.) with a view to their valorization in the Ivorian diet. The contents of dry matter, ash, reducing sugars, total sugars, fat, increased significantly under the effect of the germination of bean seeds. In addition, the mineral contents (Calcium, Magnesium, Iron, Sodium, Potassium) of sprouted bean samples are statistically different from those of ungerminated beans. Then, it was found that germination resulted in a significant increase in the contents of vitamins (A, B1, C, D and E). However, a significant decrease in the anti-nutritive compounds such alkaloid, oxalates, phytates and tannins was observed in the sprouted bean seeds. The mean values range from 45.00 ± 3.54 to 16.25 ± 1.28; from 68.29 ± 0.71 to 21.32 ± 0.18; from 81.72 ± 2.48 to 38.14 ± 1.76 and from 51.58 ± 0.26 to 19.35 ± 0.53 per cent respectively. Thus, germination is an effective processing method for increasing vitamins and mineral bioavailability, and for reducing significantly anti-nutritve compounds after the bean seeds germinate.

Biofloc technology is a new alternative in addressing water quality problems in aquaculture which is adapted from conventional domestic waste processing techniques. The main principle applied in this technology is water quality management which is based on the ability of heterotrophic bacteria to utilize organic and inorganic N in water. In a balanced C and N condition in water, heterotrophic bacteria which will utilize N, both in organic and inorganic form, are present in water for the formation of biomass so that the concentration of N in water is reduced. Several types of bacteria that are often used in biofloc are Bacillus sp., Bacillus subtilis, Pseudomonas sp., Bacillus lichenoformis, Bacillus pumilus; Lactobacillus sp.; Bacillus megaterium .  Microbes play key role in the biofloc systems. Microbes associated with floc after consumption help to improve digestion, reduces FCR reduces dietary protein level and heterotrophic bacteria, which together probiotic bacteria, inhibit the development of potential pathogen bacteria. With biofloc there are some improves in different aspects during culture like higher growth rates, increased survival, improved water quality, reduced amount of water used and decrease in diseases. Thus, role of microorganisms is important in biofloc system; therefore, it is necessary to carry out more studies related to identification of microbes that can be present in biofloc systems.

A field experiment was conducted during rabi season of 2017-18 at Agricultural College Farm, Bapatla to study the effect of seed pre - treatment and foliar application of zinc on dry matter production, partitioning and yield of mungbean under water stress. The experiment was laid out in a split plot design with three replications consists of two main treatments viz., no stress i.e. control (M0) and stress from flowering stage (i.e. from 30 DAS) up to harvest (M1) and seven sub-treatments viz., no zinc application (S0), seed treatment with 0.05% and 0.075% ZnSO4 solutions for 5 hrs before sowing (S1 and S2), foliar spray of 300, 400 and 500 ppm ZnSO4 at 30 DAS (S3, S4 and S5) and water spray at 30 DAS (S6). The results showed that leaf, stem, reproductive parts, total dry matter and seed yield was decreased by 23.0, 23.3, 15.3, 18.7 and 33.6 per cent, respectively in the plants that were subjected to stress from flowering stage over control plants. Foliar zinc spray @ 500 ppm at 30 DAS increased the leaf, stem, reproductive parts dry matter, total dry matter and seed yield by 24.6, 24.8, 20.9, 22.5 and 55.2 per cent, respectively, over untreated plants. Normal irrigated plants sprayed with zinc @ 500 ppm (M0S5) recorded the highest mean values of above parameters and the lowest mean values were recorded by the stressed plants with no zinc application (M1S0). Under water stress, mungbean plants sprayed with zinc @ 500 ppm at 30 DAS (M1S5) increased the leaf, stem, reproductive parts, total dry matter and seed yield by 17.6, 16.4, 23.9, 21.3 and 42.0 per cent, respectively, over unsprayed plants (M1S0).

Published: May 2021

The tobacco caterpillar, Spodoptera litura is a polyphagous pest with attacking almost 290 host plants species globally causing a wide range of yield losses to the agricultural crops. In this investigation symbiotic bacteria of entomopathogenic nematodes were evaluated for their insecticidal activity against larvae of S. litura under lab conditions. The intact cell suspension and cell-free extract were screened for their bacterial pathogenicity and the results showed mortality of larvae after 24h of post treatment. The percent mortality treated with intact cell suspension was significantly higher in larvae treated with EPB3 strain with 90% which was on par with the reference strain Bacillus thuringiensis after 72h of post treatment. There is no significant difference among the larval mortality treated with cell-free supernatant. The virulence test was carried out to find out the LD50 and LT50 against the larvae and the results showed that EPB3 and B. thuringiensis required 104 CFU for 50% lethality of larvae with a media lethal time of 24h and 22h, respectively when treated with cell suspension. In case of larvae treated with cell-free extract, LD50 value with 105-106 CFU with a median lethal time ranging from 33-45h. The results showed that the isolates EPB3 (Xenorhabdus nematophilus) is comparatively more virulent than other Photorhabdus isolates against the test insect S. litura. Further these symbiotic bacteria can be screened for their biocontrol efficiency under greenhouse and field conditions and can be developed as potential biopesticides against the insect pests.
