Molecular architecture of Gαo and the structural basis for RGS16-mediated deactivation [PDF]

, 2008
Heterotrimeric G proteins relay extracellular cues from heptahelical transmembrane receptors to downstream effector molecules. Composed of an α subunit with intrinsic GTPase activity and a βγ heterodimer, the trimeric complex dissociates upon receptor ...

Measurements of 2-D flow parameters around rectangular prisms arranged at the ground

Budownictwo i Architektura, 2008
Measurements of 2-D flows around a square and a rectangle (ratio 2:1) in wind tunnel have been presented in this paper. The results of these measurements presented here are pressure and standard deviation distributions on the models’ walls, components of

MEMD-Based Hybrid Modal Identification for High-Rise Structures with Multi-Sensor Vibration Measurements

Applied Sciences, 2022
Although widely used in various fields due to its powerful capability of signal processing, empirical mode decomposition has to decompose signals separately, which limits its application for multivariate data such as the structural monitoring data ...

Analysis of influence of the geometric parameters of mast systems on the natural frequency and vibration mode spectrum

MATEC Web of Conferences, 2017
Natural frequencies and eigenmodes of oscillations are the determining values in the study of dynamic processes in many constructions, including mast systems when they are affected by time-varying loads: wind, seismic, etc. [7].

Exact solution of the differential equation of transverse oscillations of the rod taking into account own weight

MATEC Web of Conferences, 2017
The free transverse oscillations of the rod of uniform cross section taking into account its own weight are considered in this work. The appropriate partial differential equation of transverse oscillations of a rod was reduced to two ordinary ...

Solution to excessive vibration of floors in a steel structured industrial building

Budownictwo i Architektura, 2008
This paper deals with the problem of vibration that occurs in many industrial buildings. It covers the complete procedure of handling such tasks. Two buildings in a “Lubelski Wegiel S.A.” coal mine were examined in 2003 – 2005.

Durability of self-healing concrete [PDF]

MATEC Web of Conferences, 2019
Application of self-healing concrete reduces the need for expensive maintenance and repair actions. However, the durability of self-healing concrete has only been scarcely investigated.

Experimental studies of fiber concrete creep

MATEC Web of Conferences, 2017
The results of two-stage experimental studies of the strength and deformation characteristics of fibrous concrete reinforced with steel fiber. In the experiments we used steel fiber with bent ends, which practically does not form "hedgehogs", which ...

The influence of SAPs on chloride ingress in cracked concrete [PDF]

MATEC Web of Conferences, 2019
Super Absorbent Polymers (SAPs) have proven to be effective as a self-healing agent for regaining the liquid tightness of cracked concrete. This is due to their large swelling capacity which allows them to (partially) block cracks which are in contact ...
