Three of the largest granite porphyries northern Portugal were studied to improve current knowledge on regional felsic vein hypabyssal magmatism. All exhibit microcrystalline groundmasses variable granularity (composed quartz, K-feldspar, and muscovite), plagioclase, biotite, cordierite phenocrysts, antirapakivi rapakivi feldspars, embayments in enrichments rare metal incompatible elements. The...

This study investigates the impact of carbon on kinetics spark plasma sintering (SPS) nano- and submicron powders WC-10 wt.%Co. Carbon, in form graphite, was introduced into by mixing. The activation energy solid-phase determined for conditions isothermal continuous heating. It has been demonstrated that increasing content leads to a decrease fraction ?-phase particles shift shrinkage curve tow...

In this paper, we study the role of degree mixing in the naming game. It is found that consensus can be accelerated on disassortative networks. We provide a qualitative explanation of this phenomenon based on clusters statistics. Compared with assortative mixing, disassortative mixing can promote the merging of different clusters, thus resulting in a shorter convergence time. Other quantities, ...

in this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. in this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

A Laser Induced Fluorescence technique (LIF) has been used to study the mixing behavior of two emerging streams in a T-Type mixing chamber. A mixing index on the basis of digital image light intensities is calculated. It has been shown that averaging over more than 800 images leads to a stable mixing index calculation. Moreover, the effect of equal and un-equal flow rates on the mixing behavior...

The barrier layer (BL) is an expansive halocline commonly found in the western equatorial Pacific, long been thought to inhibit entrainment of colder thermocline water into surface mixed (ML), consequently facilitating development El Niño. But here we find frequent turbulent mixing BL from both direct turbulence measurements and indirect estimates within 11-year-long Argo profile data set. obse...

For the A = 32, T = 2 quintet we provide a unified theoretical description for three related aspects of isospin mixing: the necessity of more than three terms in the isobaric mass multiplet equation, isospin-forbidden proton decay in 32Cl, and a correction to the allowed Fermi β+ decay of 32Ar. We demonstrate that all three effects observed in experiment can be traced to a common origin related...

Different immunoassay-based methods have been devised to detect protein targets. These methods have some challenges that make them inefficient for assaying ultra-low-amounted proteins. ELISA, iPCR, iRCA, and iNASBA are the common immunoassay-based methods of protein detection, each of which has specific and common technical challenges making it necessary to introduce a novel method in order to ...

An ultrasensitive microRNA assay was developed with one-step loop-mediated isothermal amplification (LAMP) initiated by the target microRNA.

Gas mixing in a T-shape micro mixer has been simulated using the Direct Simulation Monte Carlo (DSMC) method. It is considered that the adequate mixing occurs when the mass composition of the species, CO or N2, deviates below 1 % from their equilibrium composition. The mixing coefficient is defined as the ratio of the mixing length to the main channel’s height. As the inlet Kn increases, while ...
