Unlike conductors and semiconductors, super conducting materials are relatively rare. Again, these exhibit conductivity only at low temperature. In this chapter, an attempt has been made to present a brief historical background of discovery conductors. This is followed by presentation unusual magnetic properties materials, type 1 2 theories hypothesis proposed explain materials. Crystal structu...

malignant germ-cell tumors (mgct) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. endodermal sinus tumor (est) forms the most common histologic subtype of mgct. the vagina is an extremely rare site for gcts. an 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina. she was pale and a mass was palpable ...

concentrations of 42 trace elements, including rare earths, in croatian thermal waters wereinvestigated. originating from different parts of croatia, i.e. different types of aquifers, studied thermal watersprovide insight into the range of concentrations of broad spectrum of elements in croatian thermal waters.covering a wide range of temperature (30 - 92 °c), studied thermal waters are general...

Zinc oxide is a very interesting material for several technological applications. The properties of ZnO materials have been investigated and the influence of the 3D structure has been evaluated. Controlling experimental parameters is possible to obtain branched structures, which results in the preparation of materials presenting high surface area. Herein, we present a hydrothermal procedure to ...
