Phylogenetic analysis of killer whale (Orcinus orca) and humpback whale (Megaptera novaeangliae) populations along the Northern Norwegian fjords and adjacent waters

Killer whales (Orcinus orca) and humpback whales (Megaptera novaeangliae) are two widely distributed cetacean species and both seasonally congregate in the waters off the fjords in Northern Norway to feast on the Norwegian Spring Spawning herring (Clupea harengus). With phylogenetic analysis of complete mitochondrial genomes, obtained by shotgun sequencing, from individuals sampled through four years, this study has attempted to shed light on the geographical origin and phylogenetic position of Norwegian killer whales and humpback whales in the global context of each species. In total, 19 haplotypes were identified among 134 killer whales, and 18 haplotypes were identified among 94 humpback whales. The killer whales sampled in Northern Norway showed structuring between individuals and cluster in a clade with other individuals from Eastern North Atlantic Ocean previously described in literature. The humpback whales showed less clear clustering within the global context but have revealed a potential connection of four individuals with haplotypes from the Southern Hemisphere. Overall, this study suggests that the feeding aggregations in Northern Norway gather killer whales mainly from Eastern North Atlantic Ocean, and humpback whales from the North Atlantic and possibly from the South Atlantic Ocean

'Em todas as coisas a mudança é doce': Varietas e paixão na música italiana renascentista

Neste estudo investigamos a procura ocorrida durante a Renascença por uma música emocionalmente envolvente. Por meio do estudo dos redescobertos tratados de retórica da Antiguidade, os teóricos da música na Itália reforçam a ligação entre música e poesia e aplicam a máxima de Platão de que a música deve servir ao texto. Mediante estudos de fontes primárias – Tinctoris, Ganassi, Vicentino, Zarlino e Alberti – e secundárias sobre teóricos como Cí­cero e Quintiliano, elementos da retórica, principalmente decorum e pronuntiatio, são abordados para dar suporte à hipótese de que o conceito retórico de varietas foi usado como meio para criar expressividade musical

O etnólogo pela pena: meditações póstumas sobre escolhas monográficas

Este artigo oferece uma reavaliação crítica do processo de elaboração de O fantasista e o flagelo: sentidos de si e de África para Günther Theodor Tessmann (1884-1969), uma monografia de graduação que se debruça sobre a trajetória de vida de um etnólogo alemão. Por uma perspectiva de bastidores, a abordagem da análise se dará em primeira pessoa, tratando a fundo as vias sinuosas que originam certas escolhas metodológicas, interrogando seus fundamentos subjetivos e suas consequências objetivas para a artesania de um texto que se apresenta como uma contribuição para o campo das ciências sociais

Foam mat drying of yacon juice: Experimental analysis and computer simulation

Abstract The foam mat drying of yacon juice (YJ) and concentrate yacon juice (CYJ) was conducted under various conditions of thickness of product (0.5, 1.0 and 1.5 cm) and air temperature (50, 60 and 70 °C). After drying the resulted dry powder was removed from the metallic tray and pulverized. Layer thickness and air temperature influenced statistically ( p > 0.5) drying time, moisture content and water activity (Aw) of the product. The shortest drying time to reach the desired Aw (0.1–0.3) corresponds to the condition of 0.5 cm and 70 °C for both juices – 59 and 65 min for the YJ and CYJ, respectively. The process was modeled in terms of heat and mass transfer and then simulated by a finite element method software. The model was able to predict the process satisfactorily and the foam drying technique allowed to obtain yacon powder of good quality, which can be inserted in various food formulations

Parâmetros interpretativos para a sonata para violino solo em lá menor, BWV 1003 de J. S. Bach

Resumo: Este trabalho trata de questões de interpretação de música barroca, mais especificamente de parâmetros interpretativos para a Sonata para Violino solo em Lá menor, BWV 1003 de Johann Sebastian Bach. A sonata faz parte de um conjunto de obras que são referência absoluta no repertório para violino e imprescindíveis na formação violinística. O estudo traz um resumo do debate travado no final do século XX sobre o papel do intérprete e sua relação com o texto musical e com o compositor. É apresentada uma síntese da crítica e autocrítica feita da interpretação historicamente informada e chega-se à conclusão que o movimento de música antiga é legítimo, trazendo diversificação para o cenário interpretativo. Para contextualizar a sonata, traço um histórico da música escrita para violino desde o início do século XVII até a gênese dos Sei Solo por volta de 1720. Uma análise é feita de sete gravações diferentes da sonata, quatro modernas e três com violino barroco, e estas são confrontadas com ou comparadas à literatura sobre interpretação dos últimos 300 anos

Almond and peanut flours suppelmented with iron as potential ingredients to develop gluten-free cookies

Brazil is the second biggest worldwide producer of cookies and there are many varieties in the market; however, only a few are gluten-free. The objectives of this work were to formulate two gluten-free cookies added with iron, peanut or almond, and analyze their physicochemical, chromatic and sensory properties. Moisture, instrumental color (L*, a*, b* and C*), ash, proteins, lipids, iron, carbohydrates (estimated by difference), and water activity were determined. The acceptance of the products was assessed by 115 untrained taste panelists using a five-point hedonic scale. The data collected from the physicochemical analyses were submitted to Levene's, ANOVA, and Tukey's tests, which showed statistical difference (p < 0.05) in all the attributes for centesimal composition, water activity, and color of the cookies. Peanut and almond cookies could be considered sources of iron once they presented at least 15% of the daily recommended value of intake. They also garnered acceptance indexes of 80 and 85%, respectively, concluding that both formulations developed in this study were source of iron and contained high concentration of lipids and proteins with great sensory acceptance, suggesting their potential consumption by gluten-intolerants
