In this paper we propose a foundational vision of e-Services, in which we distinguish between the external behavior of an e-Service as seen by clients, and the internal behavior as seen by a deployed application running the e-Service. Such behaviors are formally expressed as execution trees describing the interactions of the e-Service with its client and with other e-Services. Using these notio...

Plant nutritionist have traditionally considered the obvious way to feed plants is through the soil, where plant roots are meant to uptake water and nutrients, but in recent years foliar feeding has been developed to supply plants with their nutritional needs. The development of pressurised irrigation equipment such as drip irrigation has promoted the need for water-soluble fertilisers, as clea...

Background and objectives: Echinophora platyloba is used for flavoring foods, cheese and yoghurt. Despite several pharmacological studies on the plant, no attempt has been made to isolate the non-volatile secondary metabolites and assess the antimicrobial effects. So, phytochemical investigation seems to be useful for better use of this plant. Methods: </strong...

The genus Enterobacter comprises a range of beneficial plant-associated bacteria showing plant growth promotion. Enterobacter ludwigii belongs to the Enterobacter cloacae complex and has been reported to include human pathogens but also plant-associated strains with plant beneficial capacities. To assess the role of Enterobacter endophytes in hydrocarbon degradation, plant colonization, abundan...

Since years ago, phytopharmaceutical drugs have been used by various societies, as a traditional treatment. Echinacea purpurea (Asteraceae) is the best known of the dozen or so species of the genus Echinacea, a group of perennial prairie wildflowers native to the central grasslands of North American. E. purpurea is cultivated widely throughout the United states, Canada and Europe, although it h...

Plant genomics and phenomics represents the most promising tools for accelerating yield gains and overcoming emerging crop productivity bottlenecks. However, accessing this wealth of plant diversity requires the characterization of this material using state-of-the-art genomic, phenomic and molecular technologies and the release of subsequent research data via a long-term stable, open-access por...

15 16 Here we investigate relationships between NDVI, Biomass, and Leaf Area Index (LAI) for 17 six key plant species near Barrow, Alaska. We explore how key plant species differ in 18 biomass, leaf area index (LAI) and how can v e g e t a t i o n spectral indices be used to 19 estimate biomass and LAI for key plant species. A vegetation index (VI) or a spectral 20 vegetation index (SVI) is a q...

Sessile organisms often exhibit morphological changes in response to permanent exposure to mechanical stimulation (wind or water movements). The adaptive value of these morphological changes (hydrodynamic performance and consequences on fitness) has not been studied extensively, particularly for higher plants submitted to flow stress. The aim was to determine the adaptive value of morphological...
