Mechanical Performance and Durability of Concretes with Partial Replacement of Natural Aggregates by Construction and Demolition Waste

open access: yesWaste
This study investigated the mechanical performance and durability of concretes produced with varying proportions of recycled coarse aggregate from construction and demolition waste (CDW), ranging from 0% to 100% replacement of natural coarse aggregate ...

Investigation of measurement method of saturation magnetization of iron core material using electromagnet

open access: yesAIP Advances, 2018
This paper discusses a measurement method for saturation magnetizations of iron core materials using an electromagnet, which can apply an extremely large magnetic field strength to a specimen.

Extraction of Organic Acids with Hydrophobic Eutectic Mixtures Containing Terpenoids and Decanoic Acid

open access: yesJournal of Chemical Engineering of Japan, 2023
In this study, we prepared eutectic mixtures containing decanoic acid as the hydrophobic hydrogen bonding donor, a lidocaine analog, and quaternary ammonium salt or terpenoid as the hydrophobic hydrogen bonding acceptor.

Hydrodynamic Characteristics of Two Side-by-Side Cylinders at a Pitch Ratio of 2 at Low Subcritical Reynolds Numbers

open access: yesFluids, 2022
Isothermal turbulent flow around circular cylinders arranged side-by-side was numerically simulated on a commercial finite-volumes platform, ANSYS® CFX, version 2020 R2. The turbulence was modeled by using k-ω shear stress transport (k-ω SST).

Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]

open access: yes, 2004
Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.

GMRT radio continuum study of Wolf Rayet galaxies I: NGC 4214 and NGC 4449

open access: yes, 2014
We report low frequency observations of Wolf-Rayet galaxies, NGC 4214 and NGC 4449 at 610, 325 and 150 MHz, using the Giant Meterwave Radio Telescope (GMRT). We detect diffuse extended emission from NGC 4214 at and NGC 4449.

Specific Extraction of Aspartic Acid and Tyrosine with Aqueous Two-phase Systems Formed by Hydrophilic Organic Solvent and Monomeric Sugars

open access: yesJournal of Chemical Engineering of Japan, 2023
An aqueous two-phase system (ATPS) formed by hydrophilic organic solvent and sugars is environmentally benign and has the advantages of fast phase separation.

Product mixing in the alternating group [PDF]

open access: yes, 2016
We prove the following one-sided product-mixing theorem for the alternating group: Given subsets $X,Y,Z \subset A_n$ of densities $\alpha,\beta,\gamma$ satisfying $\min(\alpha\beta,\alpha\gamma,\beta\gamma)\gg n^{-1}(\log n)^7$, there are at least $ (1+o(

MN 610 – barley cultivar

open access: yesCrop Breeding and Applied Biotechnology, 2005
Barley cultivar ‘MN 610’ was developed by Bebidas das Américas (American Beverage Company -AmBev). It was derived from a cross of the lines PFC 85104 x PFC 85106. ‘MN 610’ presents good adaptation and performs well in lowfertility environments.

Effect of Soil Type on Running Performance of Small Lunar Rover

open access: yesAerospace
It is very easy for a small lunar rover to slip on the regolith of the lunar surface and become stuck. Previous studies have quantitatively evaluated the effects of wheel geometry, such as elliptical or eccentric wheels, on the performance of a rover ...
