Influence of CFBC Fly Ash Chemical Composition and Mechanical Activation on the Properties of Geopolymer [PDF]

open access: yesArchives of Metallurgy and Materials
Circulating fluidized bed combustion (CFBC) fly ash has the potential as a precursor to making geopolymer concrete because of its rich silica and alumina content.

Closing in on a mechanism for activation

open access: yeseLife, 2014
When insulin-like growth factor-1 (IGF1) binds to its receptor, a physical constraint is released that allows the two transmembrane helices to come together to facilitate activation of the receptor.

Mechanisms of Opsin Activation [PDF]

open access: yesJournal of Biological Chemistry, 1996
Rhodopsin is constrained in an inactive conformation by interactions with 11-cis-retinal including formation of a protonated Schiff base with Lys296. Upon photoisomerization, major structural rearrangements that involve protonation of the active site Glu113 and cytoplasmic acidic residues, including Glu134, lead to the formation of the active form of ...

Mechanism of STIM activation

open access: yesCurrent Opinion in Physiology, 2020
Store-operated calcium entry (SOCE) through Orai ion channels is an intracellular signaling pathway that is initiated by ligand-induced depletion of calcium from the endoplasmic reticulum (ER) store. The molecular link between SOCE and ER store depletion is thereby provided by a distinct class of single pass ER transmembrane proteins known as stromal ...

Mathematical modeling of the mechanical characteristic of the activated PTFE-matrix using the method of planning the experiment [PDF]

open access: yesЖурнал інженерних наук, 2018
In this paper, the influence of the parameters of the technological process of mechanical activation on the physical characteristics of the polytetrafluoroethylene (PTFE) matrix is investigated.

The mechanism of mRNA activation

open access: yes, 2023
Summary During translation initiation, messenger RNA molecules must be identified and activated for loading into a ribosome. In this rate-limiting step, the heterotrimeric protein eukaryotic initiation factor eIF4F must recognize and productively interact with the 7-methylguanosine cap at the 5’ end of the messenger RNA and subsequently

Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

open access: yes, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

Mechanisms of Viral Activators

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 1998
Adenovirus large E1A, Epstein-Barr virus Zebra, and herpes simplex virus VP16 were studied as models of animal cell transcriptional activators. Large E1A can activate transcription from a TATA box, a result that leads us to suggest that it interacts with a general transcription factor.

Effect of La3+ Modification on the Electrochemical Performance of Na3V2(PO4)2F3

open access: yesBatteries, 2018
La3+ modification of Na3V2(PO4)2F3 was performed by the direct mechanochemically assisted solid-state synthesis of the Na3V2−xLax(PO4)2F3 compositions, and by the LaPO4 coating of the as-prepared Na3V2(PO4)2F3 via the precipitation method.
