On the influence of resonance photon scattering on atom interference
(Physica Scripta, 2010)
Here, the influence of resonance photon-atom scattering on the atom interference pattern at the exit of a three-grating Mach-Zehnder interferometer is studied. It is assumed that the scattering process does not destroy the ...
Model for practical carbonation depth prediction for high volume fly ash concrete and recycled aggregate concrete
(Elsevier, 2019)
The reuse of industrial residue streams such as fly ash (FA) or waste materials such as recycled concrete aggregate (RCA) can be beneficial both from an economic and an ecological point of view. Extensive research, ...
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction
(American Association of Physics Teachers - AAPT.org, 2019)
Recently, Panuski and Mungan presented the results of their study of light diffraction from a variable-width single slit by observing and measuring the diffraction pattern on an observation screen placed at a fixed distance. ...
Alkali-activated concrete with Serbian fly ash and its radiological impact
(Elsevier, 2016)
The present paper reports the results of a study on different types of fly ash from Serbian coal burning power plants and their potential use as a binder in alkali-activated concrete (AAC) depending on their radiological ...
Environmental assessment of green concretes for structural use
(Journal of Cleaner Production, 2017)
This paper presents a comparative environmental assessment of several different green concrete mixes
for structural use. Four green concrete mixes were compared with a conventional concrete mix: recycled
aggregate concrete ...
A database on flexural and shear strength of reinforced recycled aggregate concrete beams and comparison to Eurocode 2 predictions
(Construction and Building Materials, 2016)
A comprehensive database of recycled aggregate concrete and companion natural aggregate concrete beams’ flexural and shear strength was compiled from 217 experimental results. Strict criteria were applied to determine the ...
Bed-mounted Electro Magnetic meters: Assessment of the (Missing) Technical Parameters
(Elsevier, 2019)
Flow measurements in Urban Drainage Systems (UDS) are essential for pollution control and system management. Since the accuracy of, today the most popular, Acoustic Doppler Velocimeters is impeded by several factors, this ...
On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Deflection control for reinforced recycled aggregate concrete beams: Experimental database and extension of the fib Model Code 2010 model
(Structural Concrete, 2019)
Recycled aggregate concrete (RAC) has emerged as a viable solution for
solving some of the environmental problems of concrete production.
However, design guidelines for deflection control of reinforced RAC
members have ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high-volume fly ash concrete ...
