Contrasting crustal evolution processes in the Dharwar craton: Insights from detrital zircon U–Pb and Hf isotopes
New in situ U–Pb-Hf analyses of detrital zircons from across the Archaean Dharwar craton indicate significant juvenile crustal extraction events at ~3.3 and 2.7 Ga, and continuous extraction from 3.7–3.3 Ga. Reworking in the older western block at ~3.0 Ga marks the onset of cratonisation, most likely due to ‘modern’ plate tectonic processes, while reworking in both the western and young...


Early Paleozoic tectonic evolution of the North Qinling orogenic belt: Evidence from geochemistry, phase equilibrium modeling and geochronology of metamorphosed mafic rocks from the Songshugou ophiolite
The Shangdan suture zone (SSZ) is the main collisional boundary between the North China Craton and the South China Craton, along which discontinuous Paleozoic ophiolites and subduction-accretion related volcanic arc assemblages occur. Here we report the petrology, geochemistry, geochronology and phase equilibria modeling of garnet amphibolite from the Songshugou ophiolite which is one of the la...
Anatomy of zircon growth in high pressure granulites: SIMS U-Pb geochronology and Lu-Hf isotopes from the Jiaobei Terrane, eastern North China Craton
Granulite facies rocks that witnessed high pressure and high temperature metamorphism preserve important records of the growth and recrystallizaton of zircons during the multiple stages of tectonic evolution of orogenic belts developed in complex subduction-collision settings. Here we investigate zircons in the Paleoproterozoic high pressure (HP) granulites from Jiaobei Terrane in the eastern N...


Estimating the oxidative ratio of UK peats and agricultural soils
Organic matter in the terrestrial biosphere has a fundamental role in moderating the exchange of CO2 between the atmosphere and the biosphere. One important property of organic matter is its oxidative ratio (OR); that is, the ratio of moles O2 released per mole CO2 sequestered through photosynthesis, that is, the lower the OR, less O2 is released per mole of CO2 fixed. In global assessments of ...
A 3D front-tracking approach for simulation of a two-phase fluid with insoluble surfactant
Surface active agents play a significant role in interfacial dynamics of multiphase systems. While the understanding of their behavior is crucial to many important practical applications, realistic mathematical modeling and computer simulation represent an extraordinary task. By employing a front-tracking method with Eulerian adaptive mesh refinement capabilities in concert with a finite volume...


Robust high-order space–time conservative schemes for solving conservation laws on hybrid meshes
In this paper, the second-order space–time conservation element and solution element (CE/SE) method proposed by Chang (1995) is implemented on hybrid meshes for solving conservation laws. In addition, the present scheme has been extended to high-order versions including third and fourth order. Most methodologies of proposed schemes are consistent with that of the original CE/SE method, includ...
Extra Chance Generalized Hybrid Monte Carlo
We study a method, Extra Chance Generalized Hybrid Monte Carlo, to avoid rejections in the Hybrid Monte Carlo method and related algorithms. In the spirit of delayed rejection, whenever a rejection would occur, extra work is done to find a fresh proposal that, hopefully, may be accepted. We present experiments that clearly indicate that the additional work per sample carried out in the extra ch...

A mesh partitioning algorithm for preserving spatial locality in arbitrary geometries
A space-filling curve (SFC) is a proximity preserving linear mapping of any multi-dimensional space and is widely used as a clustering tool. Equi-sized partitioning of an SFC ignores the loss in clustering quality that occurs due to inaccuracies in the mapping. Often, this results in poor locality within partitions, especially for the conceptually simple, Morton order curves. We present a heuri...
Organizational Ethics Research: A Systematic Review of Methods and Analytical Techniques
Ethics are of interest to business scholars because they influence decisions, behaviors, and outcomes. While scholars have increasingly shown interest in business ethics as a research topic, there are a mounting number of studies that examine ethical issues at the organizational level of analysis. This manuscript reports the results of a systematic review of empirical research on organizational...

Thermodynamic description of the holmium–nickel system
The holmium–nickel binary system has been thermodynamically assessed by means of the Thermo-Calc software. The Redlich–Kister (Ind Eng Chem 40:345–348, 1948) polynomial was used to describe the solid and liquid solution phases. Seven intermediate phases, Ho3Ni, Ho3Ni2, HoNi, HoNi3, Ho2Ni7, HoNi5, and Ho2Ni17 were treated as stoichiometric phases. The intermetallic compound HoNi2 in this b...
Thermo-swelling behavior of Kukersite oil shale
The volumetric change (thermal expansion or thermo-swelling) of Kukersite oil shale, which contains thermo-softening organic matter, was measured up to 1,000 °C using a spring loaded linear velocity displacement transducer under inert pyrolysis conditions. The research was focused on examining the thermal swelling taking place in the thermoplastic stage of pyrolysis. A heating rate of 10 °C...

Microcalorimetric study on biodegradation kinetic of micropollutant in wastewater by ammonia-oxidizing bacteria
In the present study, microcalorimetry was used to monitor the non-growth metabolism of Nitrosomonas europaea (N. europaea) cells, which could biodegrade the micropollutant (triclosan). The presence of triclosan promote non-growth metabolism and extend the life of N. europaea cells. However, at high concentration of triclosan (4 mg L−1), the acute toxicity was induced in cells. The addition...
Polypyridinic ligand coordination to Zn 2+ and Hg 2+ metal ions
The thermodynamic parameters for the complexation reaction between Zn2+ and Hg2+ ions with the mixed amino-polypyridinic ligands tris[(2-pyridyl)methyl]amine (TPA) and 6,6-bis–bis (pyridylmethyl)aminomethyl]-2,2-bipyridine (BTPA) have been obtained in anhydrous dimethylsulfoxyde (DMSO) by using spectrophotometry, polarography, potentiometry and titration calorimetry. Complexes with stoichiome...
Kinetics of thermal degradation of water borne polyurethane dispersion containing polycaprolactone with either isophorone diisocyanate or metatetramethyl xylene diisocyanate
Water borne polyurethane dispersions synthesized using poly caprolactone–isophorone diisocyanate combination and caprolactone–metatetramethyl xylene diisocyanate combination. Thermal stability of the polyurethane dispersions was studied using thermogravimetric technique. The activation energy of decomposition of these polyurethane dispersions was determined by applying classical kinetic mod...
Determination of natural rubber/poly(methyl methacrylate) blend composition by TG/DSC technique
Natural rubber/Poly(methyl methacrylate) or NR/PMMA blends were prepared by polymerization of the methyl methacrylate monomer and natural rubber latex. Their PMMA content before and after Soxhlet extraction was determined by 1H-NMR spectrometry. In this work, the thermal properties of the same NR/PMMA blends were determined using simultaneous thermogravimetry/differential scanning calorimetry (...
