U-Th zircon SHRIMP and U-Th-total Pb monazite CHIME ages of 6 typical samples were established among different rock types outcropped into the Chah-Dozdan batholith from Iran. The zircon population displays simple internal structures in samples of the Chah-Dozdan batholith. The zircon crystals have well-preserved magmatic characteristics. In all population, the rims display younger ages than the...

A novel metamorphic anthropomorphic hand is for the first time introduced in this paper. This robotic hand has a reconfigurable palm that generates changeable topology and augments dexterity and versatility of the hand. Structure design of the robotic hand is presented and based on mechanism decomposition kinematics of the metamorphic anthropomorphic hand is characterized with closed-form solut...

Testing helps in preserving the quality and reliability of the software component thus ensuring its successful functioning. The task of testing components for which the final output for arbitrary input cannot be known in advance is a challenging task; as sometimes conditions or predicates in the software restrict the input domain Metamorphic testing is an effective technique for testing systems...

We study the effect of applying metamorphic testing to alleviate the oracle problem for numerical programs. We discuss a case study on the testing of a program that solves an elliptic partial differential equation with Dirichlet boundary conditions. We identify a metamorphic relation for the equation and demonstrate the effectiveness of metamorphic testing in identifying the error. The relation...

The measured clay-water isotope fractionation for boron was applied to natural organic-rich sediments undergoing illitization. Two field areas were chosen that show illitization occurring over a range of temperatures (80–500°C). Samples representing diagenetic temperatures of illitization (80–200°C) are from the Gulf of Mexico sedimentary basin at 4 to 6-km depth in the Eocene Wilcox Fm and Jur...

Raman-based geobarometry has recently become increasingly popular because it is an elegant way to obtain information on peak metamorphic conditions or the entire pressure-temperature-time (P-T-t) path of metamorphic rocks, especially those formed under ultrahigh-pressure (UHP) conditions. However, several problems need to be solved to get reliable estimates of metamorphic conditions. In this pa...

Metamorphic testing is a well known approach to tackle the oracle problem in software testing. This technique requires the use of source test cases that serve as seeds for the generation of follow-up test cases. Systematic design of test cases is crucial for the test quality. Thus, source test case generation strategy can make a big impact on the fault detection effectiveness of metamorphic tes...

Chloritoid and kyanite coexist in metapelites from the high-pressure/low-temperature Massa Unit Alpi Apuane metamorphic complex (Northern Apennines, Italy). The composition of chloritoid is extremely variable throughout Unit. Fe-chloritoid occurs association with hematite-free, graphite-bearing schists, whereas strongly zoned Fe-Mg found hematite kyanite. We investigated effect different bulk F...

Most of the organic nitrogen (Norg) on Earth is disseminated in crustal sediments and rocks in the form of fossil nitrogen-containing organic matter. The chemical speciation of fossil Norg within the overall molecular structure of organic matter changes with time and heating during burial. Progressive thermal evolution of organic matter involves phases of enhanced elimination of Norg and ultima...
