Las buenas decisiones no se logran fácilmente, son el resultado de un arduo ordenado proceso mental. Las condiciones cambian, así que no se debe exponer a los riesgos de una respuesta mecánica o un enfoque intuitivo. De hecho, las experiencias para decisiones rápidas pueden ser tan grandes que nos pueden llevar; sin darnos cuenta, a una trampa. El análisis de decisiones sustenta todas las funciones directivas. Nada de lo que un directivo hace es más importante que el uso de la mejor información disponible para tomar buenas decisiones. El daño causado a una organización por una decisión básicamente desacertada no puede ser evitado ni por la más cuidadosa planificación ni por una implementación básica.

These microorganisms can cause diseases in plants and animals, and might be responsible for an increase incidence of asthma and respiratory diseases in this region. A PM 2.5 air sampling station was installed in Castle Bruce, Dominica from March through July of 2002. Fourteen filters were obtained by running the air sampler continuously for 24 hour periods. The samples were collected in sterile Teflon filters (47 mm in diameter, 0.2 um pore size), inoculated in Malt Extract Agar (MEA) with lactic acid and incubated at 29° C. Colonies were counted, isolated and cultured on separate Petri dishes. Fungal classification to the genus level used macroscopic features and microscopic evaluation. The Nomarski light microscopy technique was used for identification of reproductive structures. A total of 105 colonies were isolated. Six genera including Asp...

Practical implementations of filter banks often require scaling of coefficients and differing binary word sizes to maintain dynamic range. When ...

The organism is very pleomorphic, motile and requires at least 8% (w/v) NaCl to grow. Polar lipid composition revealed the presence of a novel non-sulfate-containing glycolipid and the absence of the glycerol diether analogue of phosphatidylglycerosulfate. The G + C content of the DNA is 59 mol%. On the basis of 16S rRNA sequence data, the new isolate cannot be classified in one of the recognized genera, but occupies a position that is distantly related to the genus Haloferax. All these features justify the creation of a new genus and a new species for the family Halobacteriaceae, order Halobacteriales. The name Halogeometricum borinquense gen. nov., sp. nov. is proposed. The type strain is ATCC 700274T.
