Concentrations of the incompatible trace elements and REEs in the upper mantle rocks of the Northern Semail ophiolite are very low, as typical in the residua of partial melting and in the early products of a fractionating magma. However, their geochemical characteristics have shown indications of hydrous magmas that more likely related to a subduction environment. Melt extraction can play a cru...

This study provides an overview on the development of the guidelines and legislation related to soil contamination in Finland, with the main focus on geochemical baselines. The use of geochemical baseline surveys in the assessment soil contamination in Finland and in some other countries is briefly discussed and the current practices in Finland are presented. Finally, the geochemical baselines ...

Surface complexation modeling (SCM) has emerged as a powerful tool for simulating heavy metal adsorption processes on the surface of soil solid components under different geochemical conditions. The component additivity (CA) approach is one of the strategies that have been widely used in multicomponent systems. In this study, potentiometric titration, isothermal adsorption, zeta potential measu...

We review the subject of Kähler anomalies in gauged supergravity, emphasizing that field equations are inconsistent when the Kähler potential is non-invariant under gauge transformations or when there are elementary Fayet-Iliopoulos couplings. Flux vacua solutions of string theory with gauged U(1) shift symmetries appear to avoid this problem. The major new result is that the Kähler anomaly inv...

Just as D-brane charge of Type IIA and Type IIB superstrings is classified, respectively, by K(X) and K(X), Ramond-Ramond fields in these theories are classified, respectively, by K(X) and K(X). By analyzing a recent proposal for how to interpret quantum self-duality of RR fields, we show that the Dirac quantization formula for the RR p-forms, when properly formulated, receives corrections that...

The temporal evolution of a regional-scale persistent low-frequency anomaly is examined with data from a 2100-day perpetual January general circulation model. The persistent episodes are determined with an objective analysis of the low-pass (.10 day) 350-mb streamfunction field that uses both pattern correlations and empirical orthogonal function (EOF) analysis. The composite evolution of each ...

The overlap hypercube fermion is constructed by inserting a lattice fermion with hypercubic couplings into the overlap formula. One obtains an exact Ginsparg-Wilson fermion, which is more complicated than the standard overlap fermion, but which has improved practical properties and is of current interest for use in numerical simulations. Here we deal with conceptual aspects of the overlap hyper...

Local structural property of an image is often considered in image enhancement with various high/low pass filters. Spatial association indexes (autocorrelation, covariance, and variogram) have been commonly used to characterize the local structure of surfaces for data interpolation in kriging. Singularity is another index measuring the scaling invariant property of measures from a multifractal ...

Papua New Guinea (PNG) is located at the convergence edge of Pacific Plate and Indo-Australian Plate, consisting three units. There are chromium mineralization types in PNG. Based on national-scale geochemical mapping PNG during 2015–2018, 1399 samples stream sediments were collected from Highland Region, Peninsula, Islands. This paper preliminarily studied chromium’s background, spatial distri...
