Interaction of cement particles with water or mechanism of hydration and hardening of cement

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2018
The relevance of the research is caused by the necessity to deepen theoretical conceptions about the mechanism of cement water interaction for more efficient use of Portland cement.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

The induction of the ovulatory period

open access: yes, 2015
Dos instrumentos potentes -la gonadotropina humana y el citrato del clomiphene-- están a nuestra disposición para la inducción del período ovulatorio en todos las pacientes que demuestran un período anovulatorio de origen central: psicogénico, neurogénico e hipofisario.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Direct torque control for dual three-phase induction motor drives [PDF]

open access: yes, 2004
A direct torque control (DTC) strategy for dual three-phase induction motor drives is discussed in this paper. The induction machine has two sets of stator three-phase windings spatially shifted by 30 electrical degrees.

The Period of Induction in Blood Clotting.

open access: yesExperimental Biology and Medicine, 1927
What are the changes taking place in blood plasma from the time it is drawn until the first fibrin appears? Although this period of apparent inactivity occupies the major portion of the so called “clotting time,” it has received very little attention from students of the problem of blood clotting.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
