Engineering properties of scoria concrete as a construction material

Global Journal of Engineering Research, 2015
The weight and cost of plain concrete are part of the setbacks in its use for construction purposes especially in low-cost housing delivery. This paper reports the experimental results of samples of concrete produced from a mix combination of cement, fine aggregate (sand) and volcanic scoria as coarse aggregate.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Evaluation of lime plaster on masonry walls in historical buildings prior to renovation

Budownictwo i Architektura
This study analysed a quantitative assessment of the adhesion of lime plasters to the substrate in a historic neo-Gothic building. The diagnostics of the plasters were conducted to preserve their large surface area due to their historical value. The use

AUTOMATED CALIBRATION OF FEM MODELS USING LIDAR POINT CLOUDS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
In present work it is pretended to estimate elastic parameters of beams through the combined use of precision geomatic techniques (laser scanning) and structural behaviour simulation tools. The study has two aims, on the one hand, to develop an algorithm

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Synthesis of MnO2–CuO–Fe2O3/CNTs catalysts: low-temperature SCR activity and formation mechanism

Beilstein Journal of Nanotechnology, 2019
MnO2–CuO–Fe2O3/CNTs catalysts, as a low-dimensional material, were fabricated by a mild redox strategy and used in denitration reactions. A formation mechanism of the catalysts was proposed. NO conversions of 4% MnO2–CuO–Fe2O3/CNTs catalyst of 43.1–87.9%

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The Influence of Cl- and Ca2+ on the Passive Film of 00Cr10MoV Steel in Simulated Concrete Solution

International Journal of Electrochemical Science, 2017
The influence of Cl- and Ca2+ on the naturally growing passive film of a new, alloyed stainless steel with 10% Cr and 0% Ni was investigated by electrochemical impedance spectroscopy, Mott-Schottky curves, X-ray photoelectron spectroscopy (XPS), and ...

Resistance Properties to Chloride Ingress of Standard-Cured Concrete Made with an Admixture Incorporating Rich SiO2 and Al2O3

International Journal of Concrete Structures and Materials, 2020
In regions where the concrete structures are exposed to a salty environment, the concrete requires high resistance to chloride-ion penetration. To achieve higher resistance against chloride ingress, a pozzolanic admixture incorporating a high volume of ...
