Phytoplankton size changes and diversity loss in the southwestern Mediterranean Sea in relation to long-term hydrographic variability
(
Academic Press
, 2020 , Article)
Structural changes in plankton primary producers have large implications for food web dynamics, energy fluxes and the vertical export of biogenic particulate carbon. Here we examine phytoplankton data spanning the period ...
A computational model for suspensions of motile micro-organisms in the flow of ferrofluid
(
Elsevier
, 2020 , Article)
The performance of friction drag, heat transfer rate, and mass transfer is illustrated the in boundary layer flow region via density of motile microorganisms. Magnetic dipole in presence of Curie temperature and density ...
Nanofluid in tilted cavity with partially heated walls
(
Elsevier
, 2014 , Article)
Lattice Boltzmann Method is applied to investigate the natural convection flow utilizing nanofluids in square enclosure with partially heated walls. The fluid in the cavity is a water-based nanofluid containing different ...
An alternative proof of Lie’s linearization theorem using a new λ-symmetry criterion
(
Elsevier
, 2015 , Article)
An alternative proof of Lie’s approach for the linearization of scalar second-order ordinary differential equations is derived by using the relationship between λ-symmetries and first integrals. This relation further leads ...
Ferromagnetic effects for nanofluid venture through composite permeable stenosed arteries with different nanosize particles
(
American Institute of Physics
, 2015 , Article)
In the present article ferromagnetic field effects for copper nanoparticles for blood flow through composite permeable stenosed arteries is discussed. The copper nanoparticles for the blood flow with water as base fluid ...
A novel index based on planktonic copepod reproductive traits as a tool for marine ecotoxicology studies
(
Elsevier B.V.
, 2020 , Article)
Copepods are excellent bioindicators of climate change and ecosystem pollution in anthropized coastal waters. This work reviewed the results of previous studies examining changes in egg production rate (EPR), hatching ...
Global variability in seawater Mg:Ca and Sr:Ca ratios in the modern ocean
(
National Academy of Sciences
, 2020 , Article)
Seawater Mg:Ca and Sr:Ca ratios are biogeochemical parameters reflecting the Earth–ocean–atmosphere dynamic exchange of elements. The ratios’ dependence on the environment and organisms’ biology facilitates their application ...
Analysis of ferrite nanoparticles in the flow of ferromagnetic nanofluid
(
Public Library of Science
, 2018 , Article)
Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4—C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4—C2H6O2 (Nickel zinc ferrite-ethylene ...
MHD effects on nanofluid with energy and hydrothermal behavior between two collateral plates application of new semi analytical technique
(
Vinca Inst Nuclear Sci
, 2017 , Article)
In this study, heat and mass transfer characteristic of unsteady nanofluid flow between parallel plates is investigated. The important effect of Brownian motion and thermophoresis has been included in the model of nanofluid. ...
Mathematical analysis of ferromagnetic fluid embedded in a porous medium
(
Elsevier
, 2017 , Article)
This article focuses on the impacts of heat transport phenomenon in a ferrofluid in presence of a magnetic dipole. The flow is caused by stretching of the surface. The analysis is disclosed with porous medium and thermal ...
