Life-long learning is a key issue for our knowledge society. With social software systems new heterogeneous kinds of technology enhanced informal learning are now available to the life-long learner. Learners outside of learning institutions now have access to powerful social communities of experts and peers who are together forging a new web 2.0. This paper reviews current work in pan-European ...

Spermidine, N-(3-aminopropyl) butane-1,4-diamine, is a low-molecular-mass organic base (C7H19N3, CAS 124-20-9) and belongs to the polyamine family which includes spermine and putrescine, the direct precursor of spermidine (Figure 1). At ambient temperature (22-25 °C) spermidine is a colorless liquid or a white powder. In biological samples, the two primary amine groups and the secondary amine g...

Historically, fat was considered detrimental to health and lifespan. However, lipidomics, the quantification of all lipid molecules in a biological sample, and genetic studies in model organisms are revealing specific fats that may promote longevity. These emerging findings provide insight into the complex relationship between lipids and longevity.

Insect pollinators such as bumblebees play a vital role in many ecosystems, so it is important to understand their foraging movements on a landscape scale. We used harmonic radar to record the natural foraging behaviour of Bombus terrestris audax workers over their entire foraging career. Every flight ever made outside the nest by four foragers was recorded. Our data reveal where the bees flew ...

“That I, whose experience of teaching is extremely limited, should presume to discuss education is a matter, surely, that calls for no apology. It is a kind of behavior to which the present climate of opinion is wholly favorable. Bishops air their opinions about economics; biologists about metaphysics; inorganic chemists, about theology; the most irrelevant people are appointed to highly techni...

The purpose of the authors is to share their experience in SME’s employees training through Computed Assisted Learning and Telematics Tools. We want to show why training is a need for any company that wants to survive in a competitive market. Then we will give some good reasons for which we think this training must be done using distance learning and explain why telematics tools and multimedia ...

Overview Libraries operate within the service industry and increasingly are seeing marketing as a focus for ensuring that the services they provide are useful and appropriate. In a marketing context, users become customers; the services provided are products developed to meet customer needs; a price is involved in an exchange process (although it may not have a monetary value); the place in or ...

Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and procurement, as well as lower environmental and maintenance requirements when compared to older impregnated paper systems. The purpose of this paper is to outline some of the de...

Multiple task learning (MTL) neural networks are one of the better documented methods of inductive transfer of task knowledge (Caruana 1997). An MTL network is a feedforward multi-layer network with an output node for each task being learned. The standard back-propagation of error learning algorithm is used to train all tasks in parallel. The sharing of internal representation in the hidden nod...

Education will change tremendously within the next years. The significance of life-long learning and life accompanying education raises the need for new teaching and learning technologies. Although eLearning and knowledge management seem to fulfill the various requirements and much effort is being spent over years, the breakthrough is still missing in both fields. One reason for this is the fac...
