The glass transition activation energy‚ Et‚ is among the important characteristic parameters of the glasses. Et is defined as the amount of energy absorbed by a group of atoms in the glassy region and therefore‚ a jump from one metastable state to another is possible. In addition‚ the activation energy of glass transition can be obtained as a function of the glass transition temperature‚ Tg‚ using the second approach proposed by Kissinger [26]:

Wildlife Conservation in My Country In Malaysia‚ just like elsewhere the modern world‚ many species of wildlife are disappearing fast‚ and conservation measures are needed to prevent animals and plants from vanishing for good. Habitat destruction is a main part of the problem but many animals are being killed and taken by hunters and poachers too. Many rare animals are hunted for food and even for sport. Some are caught alive and then sold on to collectors. One of the saddest and sickest reasons

SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of
