Olive trees have been traditionally cultivated in dry conditions as it is a crop very well adapted to Mediterranean dry lands. Foliar fertilization is a widespread application method used by olive growers to correct frequent deficient levels of potassium in olive trees under rainfed conditions. Monopotassium Phosphate (MKP) is an economic and easily available fertilizer and a fast source of P a...

DEFINITION Sensor networks allow for micro-monitoring of different phenomena of interest in arbitrary physical environments. With this unique capability, sensor networks can capture the events in the real world as they happen in the form of high-resolution spatiotemporal data of various modalities, and provide the opportunity for real-time querying and analysis of the data for immediate respons...

Orchestrating learning is a quite complex task. In fact, it has been identified as one of the grand challenges in Technology Enhanced Learning (TEL) by the Stellar Network of Excellence. The objective of this article is to provide teachers and students with a tool to help them in their effort of orchestrating learning, that makes use of awareness artefacts. Using this powerful mechanism in lab ...

The grand challenge for the 21st century is to harness the accumulating knowledge of Earth’s biodiversity and the ecosystems that support it. To accomplish this, we must mobilize biological information  assemble it, organize it, and deliver it with dramatically increased capacity. We must elevate the global biological information infrastructure to a new level of capability  a “next generation...

introduction : the aim of this study was to examine and compare the apical sealing ability of ah26, ah plus and ah plus jet using a fluid filtration model. materials and methods : 70 single-rooted teeth were dissected from the cement-enamel junction. canals were prepared with protaper rotary system and manual k files and irrigated with 5.25% naocl and 17% edta. ten teeth were assigned as contro...

Systems biology is a comprehensive quantitative analysis of the manner in which all the components of a biological system interact functionally over time. Such an analysis is executed by an interdisciplinary team of investigators that is also capable of developing required technologies and computational tools. In this model, biology dictates what new technology and computational tools should be...
