Factors effecting the induction of rat forestomach hyperplasia induced by Swedish oral smokeless tobacco (snus)
(Regulatory Toxicology and Pharmacology, 2019)
Long term exposure to oral smokeless tobacco may induce lesions in the oral cavity characterized by a hyperplastic epithelium. The possible role of nicotine and the physical properties of oral tobacco for developing these ...
Evidence for Top Quark Production in Nucleus-Nucleus Collisions
(Physical Review Letters, 2020)
Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10−6 sec, thereby allowing the study of the quark-gluon plasma (QGP), a state of ...
Measurements of tt¯H Production and the CP Structure of the Yukawa Interaction between the Higgs Boson and Top Quark in the Diphoton Decay Channel
(Physical Review Letters, 2020)
The first observation of the tt¯H process in a single Higgs boson decay channel with the full reconstruction of the final state (H→γγ) is presented, with a significance of 6.6 standard deviations (σ). The CP structure of ...
Nickel vertical posts: Influence of thickness on magnetic and optical properties
(Belgrade : Institute of Physics Belgrade, 2021)
In the present study we have investigated the influence of the nickel (Ni) thin films thicknesses on their structural, magnetic and optical properties. Nickel vertical posts were deposited by Glancing Angle Deposition ...
Tunable quantum phase transitions in asymmetric HgTe/CdxHg1-xTe double quantum wells
(Belgrade : Vinča Institute of Nuclear Sciences, University of Belgrade, 2019)
The quantum spin Hall (QSH) effect is a unique phase of matter characterized by a pair of helical edge states protected by time-reversal symmetry. The existence of this phase was first theoretically proposed for graphene ...
Thermal Stability Improvement of Cr3+-Activated Broadband Near-Infrared Phosphors via State Population Optimization
(Advanced Optical Materials, 2023)
Technological progress has accelerated the researches into broadband near-infrared (NIR) luminescent materials as next-generation intelligent NIR light sources; however, poor thermal stability restricts the applications ...
Ispitivanje aktivnih ambijentalnih dozimetara u poljima pozadinskog zračenja niskog intenziteta / Assaying active ambient dosimeters at low background levels
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2019)
Etaloniranje aktivnih ambijentalnih dozimetara izvodi se pri poznatim jačinama ambijentalnog doznog ekvivalenta pri čemu se vrši korekcija na vrednost prirodnog pozadinskog zračenja (fona). Izmerenu vrednost ambijentalnog ...
Performance testing of dosimeters used in interventional radiology: Results from the VERIDIC project
(Radiation Measurements, 2021)
Interventional procedures in radiology and cardiology are associated with high dose to the patient. Accurate dosimetry is essential and calibration of the equipment is a means to provide the necessary accuracy of dose ...
Modeling of intersubband transitions in ZnO/ZnMgO Coupled Quantum Wells
(Belgrade : Institute of Physics, 2021)
In recent years ZnO has become a popular semiconductor withmany potential applications in infra-red and THz optical devices owing to awide direct bandgap (3.4 eV) in combination with relatively high exciton binding energy ...
