Electron transmission through a steel capillary
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2018)
The transmission of low-energy electrons through a macroscopic steel capillary has been investigated both experimentally and theoretically. The length of the steel capillary was L = 19.5 mm and the inner diameter was d = ...
Use of active personal dosimeters in hospitals: EURADOS survey
(Journal of Radiological Protection, 2018)
Considering that occupational exposure in medicine is a matter of growing concern, active personal dosimeters (APDs) are also increasingly being used in different fields of application of ionising radiation in medicine. ...
Optimization of formulation and process parameters for the production of carvedilol nanosuspension by wet media milling
(International Journal of Pharmaceutics, 2018)
The aim of this study is to develop nanosuspension of carvedilol (CRV) by wet media milling. Concentration of polymeric stabilizer (hydroxypropyl cellulose-HPC-SL), milling speed and size of milling beads were identified ...
Up-conversion luminescence of GdVO4:Nd3+/Er3+ and GdVO4:Nd3+/Ho3+ phosphors under 808 nm excitation
(Optical Materials, 2018)
© 2018 Elsevier B.V. In recent years, there exists a tendency in research of up-conversion materials to shift excitation from 980 nm to shorter wavelengths. Here, in order to produce up-conversion luminescence emission of ...
Erratum: A new approach on modeling of the B-VIII, the ultimate achievement of the second “Uranverain”
(Nuclear Technology and Radiation Protection, 2018)
Ferrocene-containing tetrahydropyrazolopyrazolones: Antioxidant and antimicrobial activity
(Journal of Inorganic Biochemistry, 2018)
A series of ferrocenes which contain dinitrogen-fused pyrazolidinone ring were synthesized from acryloylferrocene (4) and N,N′‑cyclic azomethine imines (3). Novel 5‑aryl‑6‑ferrocenoyltetrahydropyrazolo[1,2‑a]pyrazol‑1(5H)-ones ...
Examining the Effects of the Destroying Ammunition, Mines, and Explosive Devices on the Presence of Heavy Metals in Soil of Open Detonation Pit: Part 1—Pseudo-total Concentration
(Water, Air, and Soil Pollution, 2018)
This paper presents the results of determining the pseudo-total concentration of five heavy metals in the soil on which the destruction of ammunition, mines, and explosive devices is carried out by the method of open ...
New complexity measures reveal that topographic loops of human alpha phase potentials are more complex in drowsy than in wake
(Medical & Biological Engineering & Computing, 2018)
A number of measures, stemming from nonlinear dynamics, exist to estimate complexity of biomedical objects. In most cases they are appropriate, but sometimes unconventional measures, more suited for specific objects, are ...
Broad-band emission of A3B′B′′2O9 complex perovskites (A = Ba, Sr; B′ = Zn; B′′ = Ta, Nb) realized by structural variations of the B site order–disorder
(Journal of Materials Chemistry C, 2018)
Broad emission with a full and continuous color spectrum realized by crystal engineering is extensively desired to simulate natural sunlight and improve the white color quality. Herein, new insight into the modulation of ...
Ultra-fast hadronic calorimetry
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2018)
Calorimeters for particle physics experiments with integration time of a few ns will substantially improve the capability of the experiment to resolve event pileup and to reject backgrounds. In this paper the time development ...
