We suggest a new explanation for the presence of crustally derived zircons in the upper-mantle rocks of ophiolitic complexes, as an alternative to subduction-related models. Integrated isotopic (U-Pb, Hf, and O isotopes) and trace-element data for zircons from the Tumut ophiolitic complex (southeast Australia) indicate that these grains are related to granitic magmatism and were introduced into...

The Chenaillet Ophiolite is one of the best-preserved remnants of the Piemont-Liguria oceanic basin, a branch of the Central Atlantic that opened during the separation of Adria/Africa from Europe. Despite numerous studies of structure, petrology, geochemistry and isotope geochronology, the timing and genesis of various magmatic rocks within the Chenaillet Ophiolite are still controversial. We p...

Microbial abundance and diversity in deep subsurface environments is dependent upon the availability of energy and carbon. However, supplies of oxidants and reductants capable of sustaining life within mafic and ultramafic continental aquifers undergoing low-temperature water-rock reaction are relatively unknown. We conducted an extensive analysis of the geochemistry and microbial communities r...

BACKGROUND AND AIM Cardiovascular disease is the major cause of mortality in hemodialysis patients. Oxidative stress and hyperhomocysteinemia may contribute to an increased risk of CVD. Therefore, we assessed the status of antioxidant and homocysteine-lowering vitamins related to cardiovascular disease in hemodialysis patients at Vasei hospital in Sabzevar. METHODS In this cross-sectional stu...

This paper presents an interesting direction for using grid technique in SoC design. Its target is to build a synthetic platform called SoC-PSE to conquer major problems that designers encounter with the productivity gap between VLSI complexity and design productivity by realizing the sharing of IP cores and SoC design tools in complex network environment and facilitating the collaboration duri...

The communication interconnects among the cores of the futuristic SoC is a vital challenge. NoC is being proposed as the appropriate solution for addressing these communication challenges of complex SoCs. To address design complexity and reuse, NoC systems are typically desired to be built from predesigned and pre-verified homogenous or heterogeneous building blocks such as programmable RISC co...

Age delimitation integrated with aeromagnetometric and aerogammaspectrometric survey advances the understanding of ophiolite evolution in Brasiliano Orogen. We focused on Bossoroca ophiolite, because oceanic crustal mantle rocks contain zircon metasomatic chloritite. A metadiorite a metavolcanoclastic rock were also studied to delimit relationship between island-arc infrastructure superstructur...

UML is gaining increased attention as a system design language. This is confirmed by several reported experiences and current standardization activities such as the SysML initiative, which extends UML toward the Systems Engineering domain. This paper summarizes the main features of SysML and analyzes the synergies between Systems Engineering and complex SoC design using UML. In particular, the ...
