The Chah-Bagh gold occurrence is located in Muteh mining district, in the central part of the Sanandaj-Sirjan zone. Gold mineralization occurs in ductile to ductile-brittle shear zones and is comparable with orogenic gold deposits. Silicification and sulfidization are the most important hydrothermal alteration features in the inner parts of altered shear zones and coincide most closely with the...

In this chapter, the authors review a variety of algorithms developed by different groups for automatically segmenting structures in medical images, such as brain MRI scans. Some of the simpler methods, based on active contours, deformable image registration, and anisotropic Markov random fields, have known weaknesses, which can be largely overcome by learning methods that better encode knowled...

Mitochondrial DNA (mtDNA) haplotype diversity was determined for 46 Ngöbé Amerinds sampled widely across their geographic range in western Panamá. The Ngöbé data were compared with mtDNA control region I sequences from two additional Amerind groups located at the northern and southern extremes of Amerind distribution, the Nuu-Chah-Nulth of the Pacific Northwest and the Chilean Mapuche and from ...

Gambits are central to human decision-making. Our goal is provide a theory of Gambits. A Gambit combination psychological and technical factors designed disrupt predictable play. Chess provides an environment study gambits behavioral game theory. based on the Bellman optimality path for sequential This allows us calculate Q $$ -values where material (usually pawn) sacrificed dynamic On empirica...

one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...

today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. the optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. nebka ...

The term scatologia is derived from the Greek word, skato, for dung and logos for speech (Gayford, 1997). Thus, telephone scatologia, also referred to as telephone scatophilia and telephonicophilia, is a paraphilia (PA) characterized by a pattern of sexual arousal associated with exposing an unsuspecting victim to sexual and obscene material over the phone (Milner & Dopke, 1997; Schewe, 1997). ...
