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.

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 ...

The positional-specificity effect reveals a passive-trace contribution to visual short-term memory. [PDF]

open access: yes, 2013
The positional-specificity effect refers to enhanced performance in visual short-term memory (VSTM) when the recognition probe is presented at the same location as had been the sample, even though location is irrelevant to the match/nonmatch decision. We

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).

Memory Effect and Fast Spinodal Decomposition [PDF]

open access: yes, 2007
We consider the modification of the Cahn-Hilliard equation when a time delay process through a memory function is taken into account. We then study the process of spinodal decomposition in fast phase transitions associated with a conserved order ...

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.

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.

Graviton Mass and Memory [PDF]

open access: yes, 2018
Gravitational memory, a residual change, arises after a finite gravitational wave pulse interacts with free masses. We calculate the memory effect in massive gravity as a function of the graviton mass $(m_g)$ and show that it is discretely different from

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
