Synthesis and antibacterial activity of iron manganite (FeMnO3) particles against the environmental bacterium Bacillus subtilis
(RSC Advances, 2020)
Nanocrystalline iron manganite powder was synthesized using the sol–gel combustion process, with glycine as fuel. It was further calcined at 900 °C for 8 h, resulting in the formation of a loose cubic FeMnO3 powder with a ...
Consistency test of coincidence-summing calculation methods for extended sources
(Applied Radiation and Isotopes, 2020)
An internal consistency test of the calculation of coincidence-summing correction factors FC for volume sources is presented. The test is based on exact equations relating the values of FC calculated for three ideal ...
Photoluminescence properties of nano-sized (Lu1-xYx)PO4:Pr3+ (x = 10, 20, 30, 40, 50 at. %) phosphor powders
(Optical Materials, 2020)
Herein we present the enhancement of photoluminescence properties of nano-sized LuPO4:Pr3+ phosphor powders synthesized by sol gel process with incorporation of yttrium ions inside of this single matrix to obtain ...
Constraining theories of gravity by fundamental plane of elliptical galaxies
(Physics of the Dark Universe, 2020)
We show that fundamental plane of elliptical galaxies can be used to obtain observational constraints on metric theories of gravity. Being it connected to global properties of ellipticals, it can fix parameters of modified ...
Characterization of PM2.5 sources in a Belgrade suburban area: a multi-scale receptor-oriented approach
(Environmental Science and Pollution Research, 2020)
Designated as the most harmful for health, PM2.5 aerosol fraction was a subject of our study. It was collected for all four seasons during 2014/15 in the suburban area of Belgrade (Serbia) and analysed for Al, Si, P, S, ...
Microstructure and Wear Behavior of MMC Coatings Deposited by Plasma Transferred Arc Welding and Thermal Flame Spraying Processes
(Transactions of the Indian Institute of Metals, 2020)
In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second ...
Pregnancy-induced hypertension decreases Kv1.3 potassium channel expression and function in human umbilical vein smooth muscle
(European Journal of Pharmacology, 2020)
Voltage-gated potassium (K ) channels are the largest superfamily of potassium (K) channels. A variety of K channels are expressed in the vascular smooth muscle cells (SMC). Studies have shown that gestational diabetes ...
The role of the adenosine triphosphate-sensitive potassium channels in pinacidil-induced vasodilatation of the human saphenous vein in patients with and without type 2 diabetes mellitus
(Journal of physiology and pharmacology : an official journal of the Polish Physiological Society, 2020)
Type 2 diabetes mellitus (T2DM) increases cardiovascular complications. Diabetic vascular dysfunction is associated with the reduced activity of the different smooth muscle potassium (K+) channels. Thus, the objective of ...
Simulation-based correction of dose enhancement factor values in photon brachytherapy with metal nanoparticle targeting
(Nuclear Science and Techniques, 2020)
The purpose of this study is to investigate and quantify the influence of nanoparticle composition, size, and concentration on the difference between dose enhancement values derived from Monte Carlo simulations with ...
Calcium ions tune the beats of cilia and flagella
(Biosystems, 2020)
The cytoskeleton of cilia and flagella is so called axoneme a stable cylindrical architecture of nine microtubule doublets. Axoneme performs periodic bending motion by utilizing specific dynein motor family powered by ATP ...
