Estructura morfológica y variación topográfica del contenido lipídico en la grasa del delfín listado

We investigate stratification patterns and topographical variations in the blubber of the striped dolphin (Stenella coeruleoalba) to gain insights into its regionally-specific functions. We collected blubber from 10 stranded striped dolphins (5 females and 5 males) from the eastern coast of Spain in 2007-2009, at 11 body positions. Histological measurements (adipocyte number and area) and blubber lipid content were analysed for each position. Histological measurements revealed stratification of blubber into outer, middle, and inner layers. Both the adipocyte number and area were largest in the middle layer. The adipocyte number was higher in the outer than the inner layer, whereas the adipocyte area was higher in the inner than the outer layer. The ventral anterior position did not follow this pattern, likely due to its proximity to the acoustic blubber, which is known to have a different biochemical composition. The stratification in morphological blubber characteristics most likely reflects functional differences. The outer layer may provide structural support and act as a mechanical barrier with a minor role in energy storage. The middle layer may be responsible for thermoregulation, and the inner layer could be responsible for energy mobilization, which is favoured by its proximity to the body core and a higher vascularization. In addition, an increasing gradient from dorsal to ventral positions was observed in the mean number of adipocytes and lipid content, with the exception of the caudal region. Although both ventral and dorsal blubber can have insulator and buoyancy functions, the ventral blubber may mainly serve as an energy reserve.En el presente estudio se investigaron los patrones de estratificación así como las variaciones topográficas en la grasa del delfín listado (Stenella coeruleoalba) con el fin de conocer mejor las posibles funciones regionales de este tejido. Se recolectaron muestras de grasa en 11 posiciones corporales diferentes de 10 delfines listados (5 hembras y 5 machos) varados en la costa este de España entre los años 2007 y 2009. Las medidas histológicas (número de adipocitos y área de los mismos) y el contenido lipídico se analizaron en cada una de las posiciones. Las medidas histológicas mostraron que la grasa se estratificaba en 3 capas: externa, media e interna. Tanto el número de adipocitos como su área eran mayores en la capa media. El número de adipocitos era superior en la capa externa que en la interna, mientras que el área de los adipocitos era mayor en la capa interna que en la externa. Sin embargo, la región ventral anterior no seguía este patrón, probablemente esto sea debido a que esta región se encuentra muy próxima a la grasa acústica, que es conocida por presentar una composición bioquímica diferente al resto de grasa corporal. La estratificación morfológica observada en la grasa probablemente esté reflejando una diferenciación funcional. La capa más externa podría dar soporte estructural y actuar como barrera mecánica, con un papel menos importante como almacén de reservas energéticas. La capa media podría ser responsable de la termorregulación, mientras que en la capa interna se produciría la movilización energética, lo cual se vería favorecido por su elevada vascularización y por estar en contacto con el interior del cuerpo. Además, se observó que tanto el número de adipocitos como el contenido lipídico seguían un gradiente creciente desde las posiciones dorsales a las ventrales, a excepción de la región caudal. Aunque tanto la grasa de la región dorsal como la de la ventral pueden presentar funciones de flotabilidad y aislamiento térmico, la grasa de la región ventral podría estar actuando principalmente como región de reserva energética

Subducting slab ultra-slow velocity layer coincident with silent earthquakes in southern Mexico

Great earthquakes have repeatedly occurred on the plate interface in a few shallow-dipping subduction zones where the subducting and overriding plates are strongly locked. Silent earthquakes (or slow slip events) were recently discovered at the down-dip extension of the locked zone and interact with the earthquake cycle. Here, we show that locally observed converted SP arrivals and teleseismic underside reflections that sample the top of the subducting plate in southern Mexico reveal that the ultra-slow velocity layer (USL) varies spatially (3 to 5 kilometers, with an S-wave velocity of ~2.0 to 2.7 kilometers per second). Most slow slip patches coincide with the presence of the USL, and they are bounded by the absence of the USL. The extent of the USL delineates the zone of transitional frictional behavior

Eficiência técnica dos produtores de leite em assentados rurais da reforma agrária

This paper aimed to evaluate the technical efficiency of milk producers in the Projeto de Assentamento (PA) Feliz União, municipality of Lagoa Grande, MG. To this collected data to some of the milk production of 23 settlers in 2007 and later was used as analytical tools used Data Envelopment Analysis (DEA) to assess the technical efficiency of producers. The results show that the majority of producers (84%) are technically inefficient. Of inefficient farmers, 87% are operating under increasing returns to scale and 13% operating under diminishing returns to scale. Analyzing it is efficient and inefficient producers are mainly realizes that efficient producers are more intensive factor in the labor force and have herd dairy specialist for the activity. Technical assistance was not an important factor that explains the efficiency and inefficiency of producers.Rural settlement, DEA, Milk, Minas Gerais, Farm Management,

On-board and port 3D printing to promote a maritime plastic circular economy

Oceanic plastic pollution has become one of the most serious problems in terms of the environment, and Circular Economy (CE) strategies are being implemented to reduce it. The article presents the results of a diagnosis of plastic waste in the maritime sector and the use of 3D printing as an enabling technology of CE around plastic. Maritime industries were asked about their plastic waste generation and potential parts and components which could be replaced by equivalent parts made by 3D printing. To close the CE loop, these parts would be printed with filament from the maritime industries’ plastic waste. The article addresses this process of generating filament that enables the CE and how this printing process can be affected and corrected under on-board conditions. A polypropylene-based strapping tape waste was chosen to produce recycled filament. This filament resulted stiffer than the commercial filament and, through an additivation process, it achieved better flexural properties. Finally, the 3D printing process during on-board unstable conditions was improved by an automatic and electronic correction on the 3D printer machine itself.European Regional Development Fund | Ref.

Isotopic evidence of limited exchange between Mediterranean and eastern North Atlantic fin whales

RATIONALE The relationship between stocks of fin whales inhabiting the temperate eastern North Atlantic and the Mediterranean Sea is subject to controversy. The use of chemical markers facilitates an alternative insight into population structure and potential borders between stocks because the two areas present dissimilar isotopic baselines. METHODS Baleen plates, composed of inert tissue that keeps a permanent chronological record of the isotopic value of body circulating fluids, were used to investigate connectivity and boundaries between the stocks. Values were determined by continuous flow isotope ratio mass spectrometry. RESULTS Stable isotopes confirm that, while the two subpopulations generally forage in well-differentiated grounds, some individuals with characteristic Atlantic values do penetrate into the Mediterranean Sea up to the northernmost latitudes of the region. As a consequence, the border between the two putative subpopulations may be not as definite as previous acoustic investigations suggested. The discriminant function obtained in this study may assist researchers to use baleen plate isotopic data to assign the origin of fin whales of uncertain provenance. CONCLUSIONS This study strengthens the stock subdivision currently accepted for management and conservation while recognizes a low level of exchange between the Mediterranean and temperate eastern North Atlantic subdivisions.

O CINISMO E OS DESMANDOS DA RAZÃO: ALGUMAS QUESTÕES SOBRE A RACIONALIDADE FORMAL

Este texto procura circunscrever alguns traços de um tipo de racionalidade formal, que encontra no cinismo uma de suas expressões privilegiadas. Buscamos delimitar algumas características do modo de operação dessa razão, sobretudo enquanto negatividade ou recusa da significação própria ao seu objeto e, no limite, ao mundo. Nessa direção, tentamos, ainda, apontar alguns limites para esse projeto de formalização total e de negação completa do mundo enquanto tal

A POLÍTICA COMO ESPAÇO DE APARIÇÃO DA LIBERDADE: A RESPOSTA DE HANNAH ARENDT

Este texto procura trabalhar a noção de política formulada por Hannah Arendt, especialmente em sua relação com a intersubjetividade e com a liberdade. O que se pretende mostrar é que a autora compreende a dimensão política como intrínseca à condição humana, como o espaço partilhado por um sujeito que é originariamente ser-com e no qual todo ato livre pode aparecer, realizando-se efetivamente. Buscamos mostrar que, nessa formulação, é central a experiência do totalitarismo, a reflexão sobre o papel e o sentido da política frente a um acontecimento que parece obscurecer todas as categorias do pensamento tradicional
