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 objective of the present book, which tries to summarize in an edited format and in a fairly comprehensive manner, many of the recent technical research accomplishments in the area of Smart Actuators and Smart Sensors, is to combine researchers and scientists from different fields into a single virtual room.
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.

Anti-reflective nano- and micro-structures on 4H-SiC for photodiodes
Min-Seok Kang1, Sung-Jae Joo2, Wook Bahng2, Ji-Hoon Lee1, Nam-Kyun Kim2, Sang-Mo Koo1*
Abstract In this study, nano-scale honeycomb-shaped structures with anti-reflection properties were successfully formed on SiC. The surface of 4H-SiC wafer after a conventional photolithography process was etched by inductively coupled plasma.
