Degradation of linear alkylbenzene sulfonate (LAS) in UASB reactors was optimized by varying the bioavailability of LAS based on the concentration of biomass in the system (1.3-16 g TS/L), the hydraulic retention time (HRT), which was operated at 6, 35 or 80 h, and the concentration of co-substrates as specific organic loading rates (SOLR) ranging from 0.03-0.18 g COD/g TVS.d. The highest degra...

Abstract Nowadays supply chain management has become one of the powerful business concepts for organizations to gain a competitive advantage in global market. This is the reason that now competition between the firms has been replaced by competitiveness among the supply chains. Moreover, the popular literature dealing with supply chain is replete with discussions of leanness and agility. Agile ...

Resumen.—Otis tarda es el ave con mayor dimorfismo sexual y una de las de mayor peso entre las que conservan la capacidad de vuelo. Los machos adultos capturados en España fueron 2.48 veces más pesados que las hembras y sus medidas lineales un 18–30% mayores que las de las hembras. Entre finales del invierno y la estación reproductiva el peso medio aumentó en un 16% en las hembras y en un 20% e...

BACKGROUND In the present investigation, the effect of Candidatus Liberibacter asiaticus (Las), a bacterium considered to be responsible for causing huanglongbing (HLB) disease in citrus, on the physiology of its vector, the Asian citrus psyllid (ACP) Diaphorina citri Kuwayama, was determined. Specifically, the effects of Las infection on the susceptibility of ACP to selected insecticides were ...

The laser scanning technology has become de-facto as a successful measuring mean in numerous applications of remote sensing and mapping. A development of hardware has been followed by a development of a new data file format standard know as the American society for Photogrammetry and Remote Sensing (ASPRS) Lidar Exchange Format (LAS). This data format standard has been designed in order to make...

A partir de la pregunta planteada por Paolo Freire en su ensayo ¿Extensión o Comunicación? (1976). El artículo examina el proceso en que el desarrollo de las TIC ha sido instrumentado por algunas políticas gubernamentales en Latinoamérica ¿Ha sido este un proceso extensionista, que impone una forma de entender la realidad sobre otra; o un proceso de comunicación, guiado por un diálogo recíproco...

Bacteria communicate with each other to regulate cell density-dependent gene expression via a quorum-sensing (QS) cascade. In Pseudomonas aeruginosa, two known QS systems, las and rhl, control the expression of many factors that relate to virulence, pathogenicity, and biofilm development. Microarray studies of the las and rhl regulons led to our hypothesis that a complicated hierarchy in the QS...

With the high percentage (up to 75%) of initial lateral ankle sprains (LAS) leading to repetitive sprains and chronic symptoms, it is imperative to better understand how best to treat and rehabilitate LAS events. The purpose of this paper is to review LAS pathophysiology, predisposing factors, and the current evidence regarding therapeutic modalities and exercises used in the treatment of LAS. ...
