  • Plastic products are indispensable in our everyday life. Today, the injection molding is the most used method for producing plastics parts. Using injection molding process, the plastic materials can be melted or remelted and injected at high pressure into the mold cavity to produce parts with desired shape. I started my study on injection molding seven years ago. When I was an undergraduate student, I got acquainted with mechanics and control. Then, injection molding opened a new and interesting world for me to know mechanical engineering and plastic materials....

  • The European Union has been at the forefront of research on the environment and health for many years. Through successive European Research Framework Programmes and national science programmes, we have greatly increased our understanding of the complex links between environmental risk factors and their effects on the health of citizens, various vulnerable sections of society and the population as a whole. This accumulated scientific knowledge has helped shape national and EU policy initiatives designed to protect our environment and promote human health throughout the continent.

  • I examined the structure of the cryofractured book lung of Phidippus audax with a scanning electron microscope. Each book lung is essentially a stack of flattened air-sacs, or lamellae, which project anteriorly into the lateral hemolymph space of the anterior opisthosoma. Each lamella is roughly triangular in shape. Hemolymph flows across each lamella from the medial to the lateral side (Fig. 1). Air enters the lamellae from the third, posterior side, after passing through a network of irregular cuticular struts (air filter) which lines the atrium of the book lung.
