A comprehensive geochemical survey was conducted in the western Yilgarn Craton, Western Australia, 2007, collecting 3142 surface samples of regolith. Our study used this data to target potential sites for undiscovered buried or concealed Cu-Zn-Pb, and NiCu deposits. The core approach singularity mapping technique detecting anomalies at local scale. This work proposes a procedure create composite multi-element map by linearly combining individual element maps, using element-to-element...
Ceria (CeO2) is a candidate for arsenic removal, and characterizing its surface speciation crucial controlling removal ability. Here, we focus on arsenates exploit ab initio calculations...
Blocking angiogenesis is an attractive strategy to inhibit tumor growth, invasion, and metastasis. We describe here the structure biological action of a new cyclic peptide derived from vascular endothelial growth factor (VEGF). This 17-amino acid molecule designated cyclopeptidic inhibitor (cyclo-VEGI, CBO-P11) encompasses residues 79–93 VEGF which are involved in interaction with receptor-2. In aqueous solution, cyclo-VEGI presents propensity adopt helix conformation that was largely...
Lithium (Li) was recently added to the list of critical raw materials by European Union due its significance for green energy transition. Thus, development new toolchains make Li exploration more economic and effective is needed. Stream sediment analysis can play an important part in these tool chains. In this work, two historical stream datasets covering parts Fregeneda-Almendra pegmatite field Douro region (Portugal) were reprocessed considering distinct approaches: spatial interpolation...
FT-IR spectrometry has proved to be a useful tool for determining series of plasma molecular concentrations. Dedicated experiments were first performed test the analytical performance that could obtained by using synthesized N3-peptide exhibiting -N3 absorption centered at 2110 cm(-1), spectral region where no organic material biological samples absorbs. Further, we investigated whether this technology was able allow quantification metabolic parameters (glucose and lactic acid) within...
The basal surfaces of phyllosilicate minerals have been widely studied, whereas the edge received little attention. However, in order to simulate complete clay particles at atomic level, modeling becomes crucially important, and such are likely be far more active. We used a combination quantum potential based techniques evaluate structure pyrophyllite their interaction an aqueous environment. These include {110}, {100}, {010}, {1̅10}, {130}, {1̅30}. found that CLAYFF force field is effective...
Introduction: Myxoma is a rare benign tumor of primitive connective tissue, most commonly found in the heart. It can also occur other soft tissues, such as skin, muscles, jawbones, and near joints. Myxomas upper limb, particularly hand, are extremely rare. This case adds to limited literature on hand myxomas, providing insights into its clinical presentation, diagnosis, management. Apart from this case, only two more cases myxoma with similar topography have been described. Case Report: A...
The Beja Layered Gabbroic Sequence (LGS) was emplaced in the southern border of Ossa Morena Zone Portugal during Variscan orogeny climax. With an area 315 km2 it remains one largest synorogenic intrusions worldwide, being chiefly preserved from postmagmatic tectono-metamorphic events. intrusion hosts potentially economic oxide mineralization and ore showings developed at different evolution stages intrusion. It overlaps time Ni-Cu-PGE Aguablanca deposit (Spain), sharing also similarities...
Mineral prospectivity modelling is a geospatial technique used to predict the likelihood of discovering economically viable mineral deposits in unexplored areas. This method integrates various geoscientific data, such as geological, geophysical, geochemical, and remote sensing using simple mathematical, statistical or artificial intelligence algorithms identify regions with high potential. By expert knowledge by analysing spatial patterns correlations between known occurrences geological...
The spatial distribution of the ghost crab Ocypode quadrata (Crustacea, Brachyura) was described in five low‐energy tide‐dominated sandy beaches São Sebastião Channel (Grande, Zimbro, Pitangueiras, Cabelo Gordo, and Segredo). On each beach, zonation study performed on random 1 m wide transects sampled from water line to vegetation. In general, individuals occurred above height relation mean low (MLW) peaked between 1.5 2.0 m. were then divided into three strips (tidal levels) parallel...
ABSTRACT High concentrations of indium (In) and selenium (Se) have been reported in the Neves-Corvo volcanic-hosted massive sulfide deposit, Portugal. The distribution these ore metals deposit is complex as a result combined effects early ore-forming processes late tectonometamorphic remobilization. In Se contents are higher Cu-rich types, lower Zn-rich types. At scale, both correlate positively with Cu, whereas their correlations Zn close to zero. This argues for genetic connection between...
Abstract The E-proteins E2A, HeLa E-box binding protein, and E2-2 constitute a class of basic helix-loop-helix transcription factors that differentially affect B cell development. E2A is by far the most investigated appears to operate at several levels during ontogeny. Less known concerning role other E-proteins. To address E2-2, we have performed transfers fetal liver (FL) cells into irradiated Rag-deficient mice. Although transfer E2-2-deficient alone can reconstitute all subpopulations,...
