Wastewater-based epidemiology in countries with poor wastewater treatment — Epidemiological indicator function of SARS-CoV-2 RNA in surface waters
(Elsevier B.V., 2022)
Wastewater-based epidemiology (WBE) surveillance of COVID-19 and other future outbreaks is
a challenge for developing countries as most households are not connected to a sewerage system.
In December 2019, SARS-CoV-2 RNA ...
Span-to-depth ratio limits for deflection control of reinforced concrete elements
(Structural Concrete, 2022)
Indirect deflection control usually applies the limitation of the span-to-depth
ratio. The procedures that have developed in the past decades have mostly
been derived for predefined values of some of the relevant parameters. ...
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 ...
Numerical simulation of Submarine non-rigid landslide by an explicit three-step incompressible smoothed particle hydrodynamics
(Elsevier, 2021)
Many landslides in nature may be classified as deformable landslides. The landslide volume is usually modeled as a rheological material when SPH methods are used for landslide simulation, since these methods allow for the ...
Chebyshev polynomials and r-circulant matrices
(Applied Mathematics and Computation, 2022)
This paper connects two attractive topics in applied mathematics, r-circulant matrices and the
Chebyshev polynomials. The r-circulant matrices whose entries are the Chebyshev polynomials
of the first or second kind are ...
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 ...
Behaviour of demountable steel-concrete composite beams with bolts and headed studs
(Ernst & Sohn GmbH, 2023)
Implementation of demountable beams in steel-concrete composite floors enables
structure reuse during several life cycles, consequently leading to savings in material
consumption and reduction of emissions, providing ...
Shear behaviour of recycled aggregate concrete beams with and without shear reinforcement
(Engineering Structures, 2017)
An experimental study of the shear behaviour of recycled aggregate concrete (RAC) beams with and without shear reinforcement is presented. Nine full-scale simply supported beams were loaded in four-point bending tests until ...
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 ...
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 ...
