The concentration ratio of alkaline earth elements calcium, barium and strontium in grains of diploid, tetraploid and hexaploid wheat [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2017
Even though calcium (Ca), strontium (Sr) and barium (Ba) belong to the same group of the periodic table of elements, and thus have similar chemical features, their importance for plants differs greatly.

Effect of dissolved oxygen and chemical oxygen demand to nitrogen ratios on the partial nitrification/denitrification process in moving bed biofilm reactors [PDF]

open access: yes, 2011
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewater with high ammonium concentration or low C/N ratio.

A combination of transcriptional and microRNA regulation improves the stability of the relative concentrations of target genes [PDF]

open access: yes, 2013
It is well known that, under suitable conditions, microRNAs are able to fine tune the relative concentration of their targets to any desired value. We show that this function is particularly effective when one of the targets is a Transcription Factor (TF)

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Experimental Investigation of a Medium Temperature Single-Phase Thermosyphon in an Evacuated Tube Receiver Coupled With Compound Parabolic Concentrator

open access: yesFrontiers in Energy Research, 2021
The integration of evacuated tube receivers with non-imaging compound parabolic concentrators (CPCs) operating in thermosyphon mode provides the opportunity to deliver solar thermal energy in the medium temperature range that is suitable for many ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Electronic features of Gaussian quantum well as depending on the parameters

open access: yesCumhuriyet Science Journal, 2020
In this study, the electronic characteristics of Gaussian quantum well have been examined as dependent on the parameters such as the concentration ratio, the even power parameter and Gaussian potential range.

Long-lived submicrometric bubbles in very diluted alkali halide water solutions

open access: yes, 2012
Solutions of LiCl and of NaCl in ultrapure water were studied through Rayleigh/Brillouin scattering as a function of the concentration (molarity, M) of dissolved salt from 0.2M to extremely low concentration (2.10^-17 M ).

Effects of mixing on evolution of hydrocarbon ratios in the troposphere [PDF]

open access: yes, 2007
Nonmethane hydrocarbon (NMHC) concentration ratios provide useful indicators of tropospheric oxidation and transport processes. However, the influences of both photochemical and mixing processes are inextricably linked in the evolution of these ratios ...

Evaluating summarised radionuclide concentration ratio datasets for wildlife [PDF]

open access: yesJournal of Environmental Radioactivity, 2013
Concentration ratios (CR(wo-media)) are used in most radioecological models to predict whole-body radionuclide activity concentrations in wildlife from those in environmental media. This simplistic approach amalgamates the various factors influencing transfer within a single generic value and, as a result, comparisons of model predictions with site ...
