Allografts in PCL reconstructions

Posterior cruciate ligament (PCL) injuries are often associated with other ligament lesions. Multiligament reconstructions require an important quantity of grafts and often determine the need for cadaver allografts during the surgical repair procedures. Herein, the fundamentals of allografts that have been currently used for PCL reconstructions are overviewed. The main issues to be considered when surgeons choose this therapeutic option are also discussed

Phosphate Glasses

This chapter is dedicated to the studies on phosphate glasses, from their fundamental aspects to their most relevant applications of today. P2O5-based glasses have experienced a continuously increasing number of published works in the last decades and still they possess a bright potential. Their sometimes intricate structure has made its study a quite relevant field for the Glass Science community which attracts more and more researchers. And, on the other hand, the associated difficulties in their preparation on a large scale have led to the development of specific methods, such as those used for the melting of Nd-laser glasses. They are particularly known to have a low chemical durability, though the progress in the optimization of their composition demonstrates that can be very competitive and, in this respect, we will also pay attention to the improvement of their properties as a result of their nitridation. The structure and main physico-chemical properties of phosphate glasses will be reviewed, highlighting the most relevant and well-known applications existing nowadays, such as sealing and laser glasses, biomedical, as solid electrolytes or for the storage of wastes.F.

Organizational attractiveness is in the eye of the beholder: the interaction of demographic characteristics with foreignness

Our analysis of 4605 individual evaluations of the 60 companies in the Reputation Quotient Annual 2000 study suggests that foreign-headquartered companies are less attractive employers, whereas more international companies are more attractive. Moreover, we find that gender, race, respondent age and educational level significantly interact with our foreignness variables in predicting company attractiveness.
