14-3-3 proteins. a highly conserved, widespread family of eukaryotic proteins [PDF]

open access: yes, 1992
A family of proteins known as 14-3-3 is currently receiving increased attention by investigators studying a broad range of biological systems, including plants and invertebrates. The outstanding feature of this family is the extraordinarily high sequence

Study of de-aggregation of mechanochemically synthesized ZnSe nanoparticles by re-milling in the presence of ZnCl2 solution [PDF]

open access: yesActa Montanistica Slovaca, 2013
Conventional mechanochemical synthesis of zinc selenide, ZnSe nanoparticles was performed in a planetary ball mill by high-energy milling of zinc (Zn) and selenium (Se) powders. Mechanochemically synthesized ZnSe was subsequently re-milled in circulation

Influence of rootstocks for Sangiovese vineyards in a high-altitude region of Santa Catarina State, Brazil: Impact on sensory and quality characteristics of wines

open access: yesSemina: Ciências Agrárias, 2023
Adapting grape varieties to new viticultural regions requires studying the influence of rootstock on wine quality. This study aimed to identify rootstocks that most enhance the enological characteristics of grapes of the Sangiovese variety grown in the ...

X-ray Diagnostics of Relativistic Reflection Around Supermassive Black Holes [PDF]

open access: yes, 2011
This thesis presents an investigation into the X-ray energy and variability spectra of Seyfert galaxies. Reflection of the X-ray continuum by the accretion disc in these Active Galactic Nuclei (AGN) is expected to produce an iron line and an ...

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

open access: yesChemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

Validity and Reliability of the Self-Administered Timed Up and Go Test in Assessing Fall Risk in Community-Dwelling Older Adults

open access: yesGeriatrics
Objectives: This study aimed to evaluate the validity and reliability of the self-administered Timed Up and Go (TUG) test—a gold standard for fall risk screening—by comparing it to the traditional face-to-face assessment conducted by a physiotherapist ...

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based
