Radiation‐Absorptive Heat Transport in Buoyancy‐Driven MHD Nanofluids Flow With Cross‐Diffusion and Chemical Interaction Effects Over a Vertical Moving Plate

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This article investigates the Soret–Dufour cross‐diffusion effects on radiation‐absorptive unsteady free‐convection of magnetized nanofluids (TiO2–water$$ {\mathrm{TiO}}_2\hbox{--} \mathrm{water} $$ and Cu–water$$ \mathrm{Cu}\hbox{--} \mathrm{water} $$) flow over a vertical moving permeable plate.

Potential of the NBS SRM-607 K-feldspar as a Rb/Sr and Sr isotope standard by high precision Rb measurements using MC-ICPMS

, 2015
We report high precision Rb/Sr and Sr isotope analyses for the NBS SRM-607 standard feldspar, which is widely used as a reference material for Rb-Sr ratios as well as Sr isotope compositions.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Laser ablation Rb/Sr dating by online chemical separation of Rb and Sr in an oxygen-filled reaction cell

, 2016
The Rb-Sr beta-decay dating system is one of the most attractive tools in geochronology, as Rb is sufficiently abundant in common K-bearing minerals like biotite, muscovite and K-feldspar.

Exposure, Extinction, and Cognitive Appraisals in Autistic Adults With Social Anxiety: Evidence From a Structured Speech Exposure Task

Autism Research, EarlyView.
ABSTRACT Social anxiety (SA) is highly prevalent among autistic adults, yet little is known about how autistic people respond to common therapeutic strategies, such as exposure tasks. This study examined responses to a structured speech exposure task embedded within an 8‐week modified cognitive–behavioral therapy (M‐CBT) program.

Rb-Sr isotope systematics and Sr/Ca-Ba/Ca ratios at DSDP Hole 89-462A

, 1986
Four samples of Nauru Basin basalts (Cores 94 to 109 of Hole 462A, sub-bottom depth 1077-1209 m) have 87Sr/86Sr ratios in the range 0.7037 to 0.7038, which is distinctly higher than the ratios of N-type MORB.
