Cobertura y estructura de los bosques de mangle en la baja Guajira, Caribe colombiano OceanDocs
Orjuela Rojas, A. M.; Villamil, Carlos A.; Sanjuan-Muñoz, A..
En abril de 2007 se estimó la cobertura y se determinaron los atributos estructurales de los bosques de mangle establecidos en la Baja Guajira. La cobertura del bosque se estimó a partir de imágenes ASTER y de un mosaico de fotografías aéreas. La estructura se determinó sobre transectos de 10 m de ancho y del largo de la franja del bosque de mangle. En cada uno de éstos se identificaron y contaron los árboles de mangle, midiéndoles altura total y diámetro a la altura del pecho (DAP) y se calculó el área basal, la densidad y el Índice de Valor de Importancia (IVI). En la Baja Guajira se estimó una cobertura de mangle de 59.9 ha. Laguncularia racemosa fue la especie más frecuente (87 %) y dominante (0.54 m2 · ha-1), Rhizophora mangle se presentó en el 75 %...

Concevoir des structures pour l'élevage des poissons en mer ArchiMer
Priour, Daniel.
The quick evolution of fish farming in Europe, and its development towards the open sea needs suitable farming tools. These tools must withstand the difficult sea states, but they must be easy to use, well adapted to the fish farming and not too much expensive. This book helps the design of such tools. It defines the solicitations of the sea on all the structures, and presents rules and methods to control these solicitations. Here, a structure is composed of a rearing support, a mooring system and equipments. This book describes these components, class them and gives lists of providers. The rearing support can be a cage, a group of cages or a boat. The support can float or to be submersible. The mooring system can be made up ropes, chains, anchors,...

Development and validation of empirical models for the prediction of selected antioxidants in stored oranges CIGR Journal
OLUSHOLA, SUNMONU MUSLIU; ADESOJI, OLANIYAN MATHEW; JUNIOR, ADUBA JOSEPH.
Abstract: Empirical models were developed to predict some selected antioxidants present in stored oranges under a modified atmosphere.  Three sets of four different types of passive evaporative cooling structures made of two different materials; clay and aluminium were designed and constructed as part of the study.  One set consisted of four separate cooling chambers.  Two cooling chambers were made with aluminium container (cylindrical and rectangular shapes) and the other two were made of clay container (cylindrical and rectangular).  These four containers were separately inserted inside a bigger clay pot inter-spaced with clay soil of 5 cm (to form tin-in-pot, pot-in-pot, tin-in-wall and wall-in wall) with the outside structure wrapped with jute sack....

Estructura y regeneración del bosque de la Ciénaga de Chololón, Isla Barú, Parque Nacional Natural Corales del Rosario y San Bernardo, Caribe Colombiano OceanDocs
Osorno Arango, A. M.; Valle, A. G.; Gil Agudelo, D. L..
Los manglares son ecosistemas que representan un enlace relevante en el ambiente de transición entre los medios marino y terrestre; poseen gran importancia a nivel biológico y socio-económico, siendo un ecosistema marino estratégico. A lo largo de la costa Caribe colombiana hay varias ciénagas o lagunas costeras en cuyo borde se han establecido diversos bosques de manglar, algunos de los cuales hasta el momento no cuentan con suficiente información cienífica que los describa a nivel cualitativo y que represente sus procesos biológicos y los caracterice en forma cuantitativa. El presente trabjao de investigación contribuye al conocimiento actual de la estructura, distribución, abundancia y capacidad de regeración del bosque de manglar que circunda la...

Mata Matters: Structures AgEcon
Gould, William.
Mata is Stata’s matrix language. In the Mata Matters column, we show how Mata can be used interactively to solve problems and as a programming language to add new features to Stata. Structures are the subject of this column. Structures are an advanced programming technique that can greatly simplify complicated code.

New group of oligosaccharides excreted in honeydew from scale insects Stigmacoccus sp. And coccus hesperidium L. Ciência Rural
Bogo,Amauri.
Analysis of the honeydew from scale insects Stigmacoccus sp. and Coccus hesperidium (L.) were carried out by paper chromatography, FAB-MS and GC-MS. The results showed three components (tri-, tetra- and penta-saccharides) which were composed by 1,4 glucose(s) linked to the glucose of sucrose. The findings therefore imply significant and novel metabolic transformations of sugars by the insect and/or microbial symbionts. From these results, structures and common names as "Stigmatriose, Stigmatetraose and Stigmapentose" were proposed for these oligosaccharides because they were found initially in Stigmacoccus sp. honeydew.
