The study area is located in Jabal-Barez Ranges, southeastern part of Kerman Copper Belt (KCB), where the porphyry copper mineralization such as Kerver occurs. This article deals with the enhancement of hydrothermal alteration minerals for exploration of porphyry Cu mineralization, and differentiates intense hydrothermal alteration zones from those with low intensity. Shortwave Infrared (SWIR) ...
Since the advent of effective cytotoxic combinations in the early 1970s, results from chemotherapy for small cell lung cancer have improved very little. Maintenance chemotherapy appears of no benefit. Although attractive theoretically, "non-cross-resistant" combinations may not yet exist, and most data do not support alternating 1 regimen with another. Anticoagulant therapy with warfarin probab...
abstract in the wake of renaissance, not only then art and literature pieces but the resulting diverse expressions well reflected the turning revolts in science, philosophy, and politics, and their association which is tremendously clear even among a single artist’s works, e.g. donatello’s sculptures, transparently echoing challenges between old traditions and then new reformations vastly infl...
Gazu prospect area is located about 65Km southeast of Tabas in the southern part of Shotori range. Sub-volcanic intermediate intrusive rocks (Upper Cretaceous?), monzonitic to dioritic in composition, intruded into carbonate rocks of Shotori Formation (Triassic) which are the main source for copper mineralization in Gazu district. Alteration zones associated within the intrusive are: Quartz- ...
Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones ...
In today’s environment of shrinking resources, and consistent need for accurate inspections, simulation software is an effective cost cutting tool. CIVA is an advanced NDT simulation software dedicated to modeling ultrasonic (UT), radiographic (RT) and eddy current (ET) inspections without the need for physical test sample or inspection equipment. Each inspection module is comprised of simulati...
Since the beginning of the nineties, the CEA (the French Atomic Energy Commisssion), with developing the CIVA NDT expertise platform is greatly involved in the development of simulation tools. Over the years, and with successive versions of CIVA, the results of modeling research work have been being integrated into the software both for ultrasonics and Eddy current techniques. In order to fullf...
Collaboration networks provide a method for examining the highly heterogeneous structure of collaborative communities. However, we still have limited theoretical understanding of how individual heterogeneity relates to network heterogeneity. The model presented here provides a framework linking an individual’s skill set to her position in the collaboration network, and the distribution of skill...
In a recent publication on experimental haemarthrosis in the rabbit we described many interesting ultrastructural changes that occur in the synovial membrane (Roy and Ghadially, 1966). Two such changes attracted our attention: an increase in the number of intermediate and Type B synovial cells, and the occurrence of many small and large vesicles containing fiocculent and granular material. Howe...
