Influence of the Nonequilibrium Material State on Wear Resistance

open access: yesLubricants, 2019
The influence of the nonequilibrium state of a material on its wear resistance is investigated in this study. Using methods of non-equilibrium thermodynamics and the theory of self-organization, a non-equilibrium material is shown to possess an overall ...

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

open access: yesLubricants, 2020
In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive ...

Conserved secondary structures in Aspergillus. [PDF]

open access: yesPLoS ONE, 2008
Recent evidence suggests that the number and variety of functional RNAs (ncRNAs as well as cis-acting RNA elements within mRNAs) is much higher than previously thought; thus, the ability to computationally predict and analyze RNAs has taken on new ...

COOLAIR antisense RNAs form evolutionarily conserved elaborate secondary structures

open access: yesCell Reports, 2016
SUMMARY There is considerable debate about the functionality of long non-coding RNAs (lncRNAs). Lack of sequence conservation has been used to argue against functional relevance. We investigate antisense lncRNAs called COOLAIR at the A.

Comprehensive in vivo secondary structure of the SARS-CoV-2 genome reveals novel regulatory motifs and mechanisms

open access: yesMolecules and Cells, 2021
Severe-acute-respiratory-syndrome-related coronavirus 2 (SARS-CoV-2) is the positive-sense RNA virus that causes coronavirus disease 2019 (COVID-19). The genome of SARS-CoV-2 is unique among viral RNAs in its vast potential to form RNA structures, yet as

Unfolding/Refolding Study on Collagen from Sea Cucumber Based on 2D Fourier Transform Infrared Spectroscopy

open access: yesMolecules, 2016
We aimed to explore the differences of thermal behaviors between insoluble collagen fibrils (ICFs) and pepsin-solubilized collagens (PSCs) from sea cucumber Stichopus japonicus.

Secondary School Students’ Cognitive Structures Regarding Educational Games

open access: yesScience Education International, 2023
To employ educational games in education as intended, it is required to show students’ cognitive structures for this concept. As a result, the purpose of this research was to reveal the cognitive structures of secondary school students regarding ...

Secondary Structure and Mosaic Structure of Crystals [PDF]

open access: yesPhysical Review, 1932
In the following a brief summary is given of some of the essentials of the theory of the secondary structure. This structure is very sensitive to external disturbing effects which frequently cause the transition of crystals from thermally stable into thermally pseudostable configurations for which the term mosaic structure is proposed.
