Iron's Icy Fate

towi/n&ju irons

• With more weight concentrated higher up on the back of the "MT" blade, the effective hitting area is increased . . . yet the overall size of the blade is reduced, f i ^ means you can hit a ball easier and for greater distance and accuracy. CornDare an "MT" and a conventional iron and find out for yourself. These are the reasons thousands of golfers now playing MacGregor "MTs" are sport ing im...

Fatigue Behaviour of Synthetic Nodular Cast Irons

A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...

Geology of the Icy Satellites

In the last 25 years, the explorations of the Voyager and Galileo missions have resulted in an entirely new view of the icy worlds orbiting the giant outer planets. These objects show a huge diversity in their characteristics, resulting from their formation histories, internal processes and interactions with their space environments. This paper will review the current state of knowledge about t...

Microbial Habitability of Icy Worlds

F or most of Earth’s history, life was microscopic and, even today, microorganisms dominate the planet. Hence, we believe that, if life exists beyond Earth, it likely started as microorganisms and may remain at this stage. Much of contemporary astrobiological research focuses on the metabolic potential of microorganisms and their ability to inhabit extreme environments. The search for life beyo...
