Rising economic value of a large number of metals as a result of their importance for new technologies and industrial development has renewed worldwide interest for mineral exploration and detailed studies of ore deposits. The Dill’s (2010) “chessboard” classification of mineral deposits is the most recent attempt to provide an exhaustive overview of all mineral deposits known to date. However,...

[1] New slope measurements from the Mars Orbiter Laser Altimeter (MOLA), in conjunction with the Rock Mass Rating system (RMR), permit inversions of slope height and angle from wallrock and interior deposits within Valles Marineris troughs for strength and lithology. Wallrock (50 < RMR < 65) is stronger than interior deposits (30 < RMR < 55). These values are consistent with layered igneous roc...

INTRODUCTION Amyloidosis in elderly individuals can be an independent alteration and a characteristic of aging. However, the clinical, pathophysiologic, and biochemical characteristics of amyloidosis related to age remain uncertain.

Palaeoenvironmental research in the Southern Levant presents a series of challenges, partly due to the unequal distribution of palaeoenvironmental records and potential archives throughout the region. Our knowledge of climatic evolution, during the last approximately 25,000 years, is of crucial importance to understand cultural developments. More local, well-dated, multi-proxy studies are much ...

A patient was shown to have acute arthritis in a metacarpophalangeal joint, with local calcification indicated by x-rays. Surgical and pathological examinations showed strictly intra-articular apatite crystal deposits and an erosive osteoarthritis. These crystal deposits could account for the synovial inflammation; they are thought to be related to bone fragments embedded in the synovium. The p...
