Chemical enrichment and accretion of nitrogen-loud quasars [PDF]
Astronomy & Astrophysics, 2017 We present rest-frame optical spectra of 12 “nitrogen-loud” quasars at z ~ 2.2, whose rest-frame ultraviolet (UV) spectra show strong nitrogen broad emission lines. To investigate their narrow-line region (NLR) metallicities, we measure the equivalent width (EW) of the [O iii]λ5007 emission line: if the NLR metallicity is remarkably high, as suggested ...

International Journal of Mining Science and TechnologyThe microfine ilmenite generated during ilmenite beneficiation is challenging to separate from gangue. As a result, it is often discarded directly into tailings, causing wastage of titanium resources.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Motivations, work-family enrichment and job satisfaction: An indirect effects model [PDF]
, 2011 Self Determination Theory (SDT) recognises that people may experience their motivations as either coming from within themselves (autonomous) or from outside of themselves (controlled).

Element Nucleosynthetic Origins from Abundance Spatial Distributions beyond the Milky Way
The Astrophysical Journal LettersAn element’s astrophysical origin should be reflected in the spatial distribution of its abundance, yielding measurably different spatial distributions for elements with different nucleosynthetic sites.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

THE FIRST GALAXIES: CHEMICAL ENRICHMENT, MIXING, AND STAR FORMATION [PDF]
The Astrophysical Journal, 2010 Using three-dimensional cosmological simulations, we study the assembly process of one of the first galaxies, with a total mass of 10^8 M_sun, collapsing at z = 10. Our main goal is to trace the transport of the heavy chemical elements produced and dispersed by a pair-instability supernova exploding in one of the minihalo progenitors.

On the Use of the Multi-Site Langmuir Model for Predicting Methane Adsorption on Shale
EnergiesShale gas, mainly consisting of adsorbed gas and free gas, has served a critical role of supplying the growing global natural gas demand in the past decades. Considering that the adsorbed methane has contributed up to 80% of the total gas in place (GIP),
