The number of companies operate on a global scale is on the rise seeking profitable business opportunities in the global arena. Global businesses have unique information requirements due to the integrated businesses activities in geographically dispersed business units, sourcing up to date consolidated information from numerous business processes, operating in different time zones and managing ...

introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...

The Dehaj area, located in the southern part of the Urumieh-Dokhtar magmatic belt, is a well-endowed terrain hosting a number of world-class porphyry copper deposits. These deposits are all hosted in an acidic to intermediate volcano-plutonic sequence greatly affected by various types of the hydrothermal alterations, whether argillic, phyllic or propylitic. Although there are a handful of hithe...

The internal structure of Seafloor Massive Sulfides (SMS) deposits is one the most important and complex issues facing study modern hydrothermal ore systems. Semenov-5 field a unique area where mass wasting on slope oceanic core (OCC) exposes subsurface portion deposit offers an exceptional opportunity to observe massive sulfides that have formed not only seafloor but in sub-seafloor zones as w...

We introduce a novel type of droplet generator that produces droplets of a volume set by the geometry of the droplet generator and not by the flow rates of the liquids. The generator consists of a classic T-junction with a bypass channel. This bypass directs the continuous fluid around the forming droplets, so that they can fill the space between the inlet of the dispersed phase and the exit of...

Maya and Aztec cities exhibited a distinctive kind of low-density urbanism common in ancient Mesoamerica. The non-monumental components of these cities differed from the high-density ancient and historical cities in the Old World that are often considered the norm for pre-modern urbanism. Distinctive features include the practice of intensive agricultural cultivation within urban settlements, r...

Tooth primordia at early stages of mineralization in the sharks Negaprion brevirostris and Triaenodon obesus were examined electron microscopically for evidence of ameloblastic secretion and its relation to calcification of the enamel (enameloid) layer. Ameloblasts are polarized with most of the mitochondria and all of the Golgi dictyosomes localized in the infranuclear end of the cell toward t...

We have used the activity-dependent probe FM1-43 with electron microscopy (EM) to examine endocytosis at the vertebrate nerve-muscle synapse. Preparations were fixed after very brief neural stimulation at reduced temperature, and internalized FM1-43 was photoconverted into an electron-dense reaction product. To locate the reaction product, we reconstructed computer renderings of individual term...

The study of dispersed organic matter the Mesozoic sediments Gydan parametric well 130 (north Western Siberia) made it possible to reveal its genesis, maceral composition, and secondary changes. Obtained information allowed reconstructing catagenetic zoning section, determining position lower boundary oil occurrence, main zones gas generation
