Memory Effect in Thin Thermocycling-modified La0.67Ca0.33MnO3 Films

open access: yesMedžiagotyra, 2012
Nonhomogeneous thin La0.67Ca0.33MnO3 films, having Tm in 180 K – 200 K temperature range, were thermocycled between 80 K and 210 K using liquid nitrogen.

Effect of Magnetic Field with Parabolic Motion on Fractional Second Grade Fluid

open access: yesFractal and Fractional, 2021
This paper is an analysis of the flow of magnetohydrodynamics (MHD) second grade fluid (SGF) under the influence of chemical reaction, heat generation/absorption, ramped temperature and concentration and thermodiffusion.

Center-of-mass angular momentum and memory effect in asymptotically flat spacetimes [PDF]

open access: yes, 2018
Gravitational-wave (GW) memory effects are constant changes in the GW strain and its time integrals, which are closely connected to changes in the charges that characterize asymptotically flat spacetimes.

Determination of Trace Gold in Geochemical Samples by Flame Atomic Fluorescence Spectrometry with PUFP Separation and Enrichment

open access: yesYankuang ceshi, 2020
BACKGROUND The detection sensitivity, stability, and linear range of Au using flame atomic fluorescence spectrometry (FAFS) is comparable to the method of inductivity coupled plasma-mass spectrometry (ICP-MS).

Some New Concepts of Shape Memory Effect of Polymers [PDF]

open access: yes, 2014
In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then by injection molding to obtain ...

A Protein-Linger Strategy Keeps the Plant On-Hold After Rehydration of Drought-Stressed Beta vulgaris

open access: yesFrontiers in Plant Science, 2019
Most crop plants are exposed to intermittent drought periods. To cope with these continuous changes, plants need strategies to prevent themselves from exhaustive adjustment maneuvers.

Subjective ratings of prospective memory deficits in chronic heavy alcohol users [PDF]

open access: yes, 2002
Chronic alcohol abuse has a detrimental effect on retrospective memory. Less is known about its putative effects on everyday memory. This study looked at self-ratings of prospective memory (PM) (memory for future events). After controlling for other drug

Hydrate Formation with the Memory Effect Using Classical Nucleation Theory

open access: yesCrystals
Methane hydrate formation is analytically studied in the presence of the water memory effect using the classical nucleation theory. The memory effect is introduced as a change in nucleation site from a three-dimensional heterogenous nucleation on a solid

Application of optimal control to the dynamic advertising decisions for supply chain with multiple delays

open access: yesSystems Science & Control Engineering, 2020
This paper is concerned with application problem of optimal control to a class of dynamic advertising models with multiple delays. Here, a dynamic model with state and control delays is introduced to describe the impacts of advertising delayed and memory

Effects of alcohol on subjective ratings of prospective and everyday memory deficits [PDF]

open access: yes, 2003
Background: Research has shown that heavy alcohol use has a detrimental effect on retrospective memory. Less is known about the effect of alcohol on everyday memory.
