Acoustic-visual release and temporalities on scene : the founding of a tradition by Banda Calypso.

O objetivo deste artigo ? discutir, a partir do DVD comemorativo dos 15 anos da Banda Calypso, a proposi??o da funda??o de uma tradi??o de m?sica popular pelo grupo paraense. Para isso, em um primeiro momento, retomaremos o conceito de ?descarga ac?stica? para entender a peculiaridade do discurso do grupo frente a tradi??es intelectuais j? estabelecidas. Em seguida, abordaremos os mecanismos visuais e sonoros acionados pela Calypso no desdobramento de matrizes temporais espec?ficas. Isso permitir? refletir como essas temporalidades s?o inscritas na textualidade do pr?prio DVD. Entendemos que o ?brega?, compreendido a partir de uma refer?ncia ? matriz melodram?tica, consegue urdir tempos aparentemente desconexos e se torna um eixo condutor da narrativa.The purpose of this paper is to discuss the proposal to found a tradition of popular music made by Banda Calpyso in its 15-year commemorative DVD. Therefore, we seek to resignify the concept of ?acoustic release ?in order to understand the peculiarities of the discourse engendered by this group, especially in the questioning of established academic traditions. Then, we analyze the visual and sound mechanisms triggered by Calypso to configure specific temporalities. Our proposition is that the ?brega?, understood as a reference to a melodramatic matrix, can manage to unite seemingly disconnected times and becomes a guiding axis of the narrative

Genetic divergence and importance of morphological characters in genotypes of kale

A caracteriza??o morfol?gica de gen?tipos de couve ? necess?ria bem como as estimativas da diverg?ncia gen?tica entre os mesmos. O presente trabalho teve como objetivos estudar os caracteres morfol?gicos dos gen?tipos de couve oriundos do banco de germoplasma da UFVJM, a diverg?ncia gen?tica existente entre os gen?tipos e a import?ncia destes caracteres nas estimativas da diverg?ncia. O experimento foi conduzido no Setor de Olericultura da UFVJM, Diamantina-MG, utilizando-se o delineamento experimental em blocos casualizados com trinta gen?tipos e quatro repeti??es, constitu?das por cinco plantas. Para a caracteriza??o morfol?gica avaliaram-se em cada planta quarenta e quatro caracter?sticas. Verifcou-se que h? gen?tipos com grande diverg?ncia gen?tica entre si, sendo os gen?tipos UFLA-6 e UFVJM-24 os mais divergentes em rela??o aos demais, contudo, a maioria dos gen?tipos ? similar. Verifcou-se tamb?m que h? caracter?sticas importantes que podem ser usadas nas estimativas da diverg?nciaFunda??o de Amparo ?

We studied the morphological characters of kale genotypes originated from the germplasm bank of UFVJM, the genetic divergence among the genotypes and the importance of these characters in the estimates of divergence. The experiment was carried out in the Department of Horticulture of UFVJM, Diamantina, Minas Gerais state, Brazil, using the randomized complete block design with four replications and thirty genotypes, consisting of five plants. Forty-four traits were evaluated on each plant for morphological evaluations. Some genotypes showed high genetic divergence, such as the genotypes UFLA-6 and 24-UFVJM, which were the most divergent compared to the others. Most of the genotypes, however, were similar to each other. It was also observed that there are important characteristics that can be used in the estimation of divergence

Facile synthesis and characterization of symmetric N-[(Phenylcarbonyl) carbamothioyl]benzamide thiourea : experimental and theoretical investigations.

A thiourea derivative, N-[(phenylcarbonyl)carbamothioyl]benzamide, was synthesized and characterized by elemental analysis, thermal analysis, spectroscopic methods (Fourier transform infrared (FTIR), UV-Vis, Raman, matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF), tandem mass spectrometry (MS/MS) and nuclear magnetic resonance (NMR)) and quantum-chemical calculations. The synthetic route was simple and efficient, conducted just by one-step and no purification step was needed. The compound crystallizes in a non-centrosymmetric orthorhombic crystal system with a P21 21 21 space group, with a= 5.06220(10) ?, b= 11.8623(3) ?, c= 21.9682(8) ?. The molecular conformation of the solid is stabilized by the N-H???O intramolecular hydrogen bond, which was present in the X-ray structure and was also found in the optimized geometry. The theoretical analysis showed that this strong interaction remains even when molecules are solvated, i.e., the rotation barrier and the hydrogen bond strength are greater than the solvent stabilization energy. In addition to this hydrogen bond effect, the relative position of phenyl groups has a certain influence on the chemical behavior of this thiourea and probably for other phenylthioureas

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Spatial evaluation of larvae of Culicidae (Diptera) from different breeding sites: application of a geospatial method and implications for vector control

Spatial evaluation of Culicidae (Diptera) larvae from different breeding sites: application of a geospatial method and implications for vector control. This study investigates the spatial distribution of urban Culicidae and informs entomological monitoring of species that use artificial containers as larval habitats. Collections of mosquito larvae were conducted in the São Paulo State municipality of Santa Bárbara d' Oeste between 2004 and 2006 during house-to-house visits. A total of 1,891 samples and nine different species were sampled. Species distribution was assessed using the kriging statistical method by extrapolating municipal administrative divisions. The sampling method followed the norms of the municipal health services of the Ministry of Health and can thus be adopted by public health authorities in disease control and delimitation of risk areas. Moreover, this type of survey and analysis can be employed for entomological surveillance of urban vectors that use artificial containers as larval habitat

Does the aggressiveness of the prey modify the attack behavior of the predator Supputius cincticeps (St\ue5l) (Hemiptera, Pentatomidae)?

Does the aggressiveness of the prey modify the attack behavior of the predator Supputius cincticeps (Stål) (Hemiptera, Pentatomidae)? The stink bug Supputius cincticeps (Stål) (Hemiptera, Pentatomidae) is a predator found in several Brazilian regions, which possesses desirable attributes as a natural control agent and in biological control programs. The aim of this study was to test if the attack behavior and predation success of S. cincticeps were affected by prey species. Larvae of Tenebrio molitor (L.) (Coleoptera, Tenebrionidae), Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae), and Thyrinteina arnobia (Stoll) (Lepidoptera, Geometridae) were offered to S. cincticeps in laboratory bioassays where predatory attack and prey defensive behaviors were observed for 2-hour periods. The attack behavior of S. cincticeps changed with the prey species offered. More than 25% of T. molitor and S. frugiperda larvae were immediately attacked, but T. arnobia was not immediately attacked by S. cincticeps. Successful attack (i.e., successful insertion of the predator stylets into the prey) depends on the region of the body attacked, with a greater proportion of successful attacks in the anterior than in the median or posterior regions. Larvae of T. arnobia and S. frugiperda displayed a sequence of abrupt head and body movements in response to S. cincticeps attack. Attempts of predation were more successful on T. molitor and S. frugiperda than on T. arnobia. Information about the differential attack behavior of S. cincticeps on different prey species is important for designing successful biological control programs using this hemipteran predator.<br>A agressividade da presa altera o comportamento de ataque do predador Supputius cincticeps (Stål) (Hemiptera, Pentatomidae)? O percevejo Supputius cincticeps (Stål) (Hemiptera, Pentatomidae) é um predador encontrado em várias regiões brasileiras, que possui atributos desejáveis como agente de controle natural ou em programas de controle biológico. O objetivo deste trabalho foi testar se diferentes espécies de presa podem afetar o comportamento de ataque e o sucesso de predação de S. cincticeps. Larvas de Tenebrio molitor (L.) (Coleoptera, Tenebrionidae), Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) e Thyrinteina arnobia (Stoll) (Lepidoptera, Geometridae) foram oferecidas a S. cincticeps, em bioensaios de laboratório, onde o comportamento de ataque do predador e o comportamento de defesa das presas foram observados por período de duas horas. O comportamento de ataque de S. cincticeps às presas apresentou variações nas frequências dos atos predatórios. O sucesso da inserção dos estiletes na presa depende da parte do corpo que é atacada (anterior, mediana ou posterior), apresentando maior sucesso quando o ataque ocorre na região anterior. As larvas de T. arnobia e S. frugiperda apresentaram maior frequência de movimentos bruscos quando atacadas por S. cincticeps, enquanto as de T. molitor não exibiram tais reações. Consequentemente, o sucesso da predação de S. cincticeps foi maior sobre T. molitor e S. frugiperda e consideravelmente menor em T. arnobia. Essas informações sobre as diferenças no comportamento de ataque de S. cincticeps a diferentes presas são úteis para os programas de controle biológico envolvendo hemípteros predadore
