6.1 Introduction The previous sections in this unit include many terms which may have been unfamiliar to you: for example, atom, element, compound, molecule and bond. Chemistry has a language all of its own and grasping the terminology can be as much of a problem as understanding the chemistry itself. In Section 6, you will consider the language of chemistry before returning to the examination of bonding.
4 Questions In what ways, if any, does the distance to a star influence its position on an H–R diagram? The distance to a star does not influence it 8.4 Fragile X syndrome Fragile X syndrome is the final example of a genetic disease considered here. What does the term ‘genetic disease’ mean? Genetic disea 8.2 Wilson's disease The effects of a protein that is absent, or present but not doing its job, may not be evident for many years. This is called late onset, and is exemplified by Wilson's disease. Many molecules within the body require small amounts of minerals such as iron, magnesium or copper to function properly. There are mechanisms for absorbing these minerals from the diet. However, in excess, these same minerals can be toxic, as is the case with copper. So there are also mechanisms for getting rid 1.5.6 Sedimentary structures Consider some of the places where sedimentary materials are moved and deposited. Are the sediments always laid down in perfectly horizontal, perfectly flat layers? No; as often as not, the depositing surface is not perfectly flat. Instead, a system of parallel ridges, or ripple marks, like the ones shown in Author(s): GS-02: Panels and workspaces Chirstmas Carp have built-in "compass" Amazon Adventure—Documenting Life in Ecuador's Yasuní National Park Creating After Effects mobile compositions Master Computer Science Didactisch pakket : Practicum osmotische verschijnselen bij planten en dierencellen Deze bundel werd samengesteld door het team achter Eurekas, de wedstrijd rond wetenschap en technologie voor het secundair onderwijs, en de lerarenopleiding van KATHO.

Dec 23 - The carp sold at Czech Christmas markets are helping scientists confirm that the fish may have geomagnetic sensing capabilities, always lining up in a north-south direction. Tara Cleary reports.
Ecuador's Yasuní Park is one of the Amazon's last wild frontiers, boasting an incredible biodiversity—treetop orchids, prowling jaguars, nearly 600 species of birds—and serving as home for two indigenous nations. But a vast untapped oil supply beneath the forest floor is attracting the attention of multinational oil companies. National Geographic sent a team of five photographers, each with a different specialty, into the heart of the Amazon to document the delicate balance of

The objective of the MSc programme in Computer Science is to prepare students to become professional computer scientists with the knowledge, capabilities and attitudes that they will need to participate (either alone or in cooperation with other specialists) in solving problems in society, science or institutions (whether private or public). Master of Science graduates have the ability to update their professional knowledge continually and to acquire knowledge independently from related fields w
The purpose of this course is to learn how to specify the behavior of embedded systems and to experience the design
of a provably correct system. In this course you will learn how to formally
specify requirements and to prove (or disprove) them on the behaviour. With a practical assignment
you will experience how to apply the techniques in practice.

Free/Open-Source Software (FOSS) has grown from small beginnings to a ma jor trend in the IT industry. Big companies like IBM have reoriented their business and are now deriving the majority of their revenues from services related to FOSS.
Countless small and medium enterprises all over the world are also successful in this area.
In this paper we propose an approach to enhance the adaptivity of an existing Website by plugging on top of it (epiphyte approach) a recommender system that displays additional
tips and functionalities in a separate window. The recommender system analyzes the way the user browses through the Website according to predefined prototypical ways of using the Website (models of use) and then proposes information or functionalities that appear useful according to this model of use. Different mo
Active participation of learners is considered a major benefit of simulation-based learning. However, in most courses only few persons can act simultaneously in the simulator while the remaining group observes the running scenario. We investigated how these observation phases can be instructionally designed for more active participation. Research in educational psychology suggests the use of collaboration scripts to structure these observation phases. A collaboration script is an instruction tha
Comparing multiple examples within problem categories is usually considered a necessary prerequisite for schema acquisition. However, there is an evident lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment - that builds up on a series of studies conducted by Quilici and Mayer (1996)
The challenge facing new technologies is whether they can contribute to a qualitative step up and to education for all as a process of facilitating the development of creative people with the ability to think critically and to engage in socially relevant decision making. In this paper, we describe a project whose purpose is to develop a learning environment that takes into account current expertise in learning theory in order to facilitate productive collaboration in a way that leads to active c
The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then pro
Le but de cet article est de faire le lien entre les expériences vécues par des étudiants durant les TP et les activités conçues et décrites par lenseignant. Nous tentons donc de déduire la nature des expériences dapprentissage vécues par les étudiants en TP, à partir du discours des enseignants sur ce quils font et ce quils demandent aux étudiants de faire. Nous introduisons un cadre théorique que nous utilisons pour caractériser des Travaux Pratiques : selon leurs buts et
