Reconstruction of the hydro generator excitation system on hydro power plant Trebinje 1 [PDF]

open access: yesTehnika, 2022
The excitation system of the hydro unit is a static self-excitation system that uses thyristor rectifiers in a three-phase fully controllable bridge connection with a digital two-channel regulation system characterized by a very fast response (eng.

Iodine molecule covalente excited states as determined by threshold electron spectrometry [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
The iodine molecule has been investigated by a threshold electron spectrometer in the incident electron energy range from 1.00 eV to 3.5eV. From the threshold electron spectrum contributions for excitation of three states known from optical ...

Cardiac tissue engineering [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
We hypothesized that clinically sized (1-5 mm thick),compact cardiac constructs containing physiologically high density of viable cells (≈108 cells/cm3) can be engineered in vitro by using biomimetic culture systems capable of providing oxygen transport ...

Engram Excitement [PDF]

open access: yesNeuron, 2019
Engram cells can encode and switch between multiple mnemonic functions, but how they intrinsically do so is unknown. Pignatelli, Ryan, and colleagues show that upon memory recall, the engram's excitability is transiently elevated, allowing its bearer to adapt to changing environments.

Dissipative Magnetic Soliton in a Spinor Polariton Bose–Einstein Condensate

open access: yesFrontiers in Physics, 2021
Magnetic soliton is an intriguing nonlinear topological excitation that carries magnetic charges while featuring a constant total density. So far, it has only been studied in the ultracold atomic gases with the framework of the equilibrium physics, where

Spectroscopic study of the light-induced changes of the core antenna complex CP43 in photosystem II

open access: yesPhotosynthetica, 2020
In this study, spectroscopic approaches were used to evaluate light-induced changes in chlorophyll protein 43 (CP43). Upon illumination, we observed chlorophyll (Chl) a bleaching with the complete opening of the tetrapyrrole ring.

Contribution to research of thermal loads in commercial vehicles powertrain mounts / Приложение к исследованию тепловой нагрузкиопоры силового привода грузового автомобиля / Prilog istraživanju toplotnih opterećenja oslonaca pogonske grupe teretnog motornog vozila [PDF]

open access: yesVojnotehnički Glasnik, 2017
Due to the effects of excitations of road micro-roughness and the powertrain as well as due to the conditions of movement (acceleration, braking, curvilinear movement), the weights of commercial vehicles perform complex spatial oscillations. The negative

Quantitative Compression Elastography With an Uncalibrated Stress Sensor

open access: yesFrontiers in Physics, 2022
Tissue stiffness is a key biomechanical property that can be exploited for diagnostic and therapeutic purposes. Tissue stiffness is typically measured quantitatively via shear wave elastography or qualitatively through compressive strain elastography ...
