Preparação e caracterização de diferentes nanotransportadores sem substância ativa

Os nanotransportadores (NT) são sistemas desenvolvidos à escala nanométrica (< 1μm) sendo usados como veículo de substâncias ativas (SA) [1]. Atualmente a maioria dos trabalhos foca o encapsulamento de fármacos e caracterização dos NT obtidos, sendo escassos os dados relativos a NT sem SA. Este trabalho teve como objectivo a preparação e caracterização de diferentes tipos de NT sem SA: lipossomas (L), nanocápsu...

Evolución del control de rendimientos en esquema de selección de la raza ovina ...

La raza ovina Segureña es una de las tres razas ovinas españolas de más relevancia en la producción de carne, en España. Su importancia también viene dada porque se constituye en la principal fuente de generación de renta de unas de las regiones más deprimidas de Europa, como es el altiplano de Granada y las Sierras de Segura y las Villas. Al estar explotada en condiciones extensivas y semiextensivas, es además...

El efecto del área de distribución de las ganaderías sobre los caracteres de cr...

Para estudiar el efecto del área de distribución de las ganaderías sobre los caracteres de crecimiento del ovino segureño fue utilizada la información de los registros de control de rendimientos obtenidos por la Asociación Nacional de Criadores de Ovino Segureño – ANCOS – durante los años comprendidos entre 2000 y 2011, y que constaron de un total de 129.377 pesadas realizadas sobre 60.461 individuos pertenecie...

Two isoforms of vasa maternal factor in Senegalese sole: Biotechnological appli...

Primordial Germ Cells (PGCs) identification and manipulation present considerable potential for hatchery practice and surrogate broodstocks. To carry out the PGCs characterization a specific molecular marker is required. The vasa gene is a good candidate to identify PGCs and others germinal cells (Nagasawa et al., 2009). The aim of this study was the cloning of the Solea senegalensis vasa cDNA and its expressio...

Is the Murciano-Granadina a single goat breed? A molecular genetics approach

The population structure of the Murciano-Granadina breed was determined using 25 microsatellites from 266 goats of seven populations. The results of the genetic differentiation analysis showed that it is possible to differentiate the Murciana and Granadina populations even though a low F ST value (0.0432) had been obtained. Individuals could be assigned to their populations with a success rate of more than 80%....

Boundary layer thickness of cylinders and plane surfaces immersed in packed bed...

In this work, boundary layer development was investigated for a mass transfer process between a moving fluid and a slightly soluble cylinder or plane surface buried in a packed bed, in alignment with the direction of flow. The bed of inert particles is taken to have uniform voidage. For this purpose, numerical solutions of the partial differential equations describing mass concentration of the solute were under...

Gla proteins as markers for studies of skeletal development and malformations i...

Evaluation of the onset and the development of skeletal structures during larval ontogeny of commercially important species in southern Iberia Peninsula and Mediterranean area (...) is essential for the successful production of high quality fish.

Geometry effects on internal flow patterns

The aim of the work presented in this paper is to look for the changes in internal flows due to the combined action of thermal effects and atmospheric wind (natural ventilation) caused by external geometry. Two different configurations are presented as an illustration of the model application.
