  • PETRENCU, Anatol (Universitatea Tehnica a Moldovei, 2020)
    La 28 iunie 1940, având susținerea Germaniei naziste, URSS a atacat România, răpindui teritorii strămoșești – Basarabia, nordul Bucovinei, Ținutul Herța. În aceste teritorii sovieticii au aplicat politici sociale, practicate ...
  • COJOCARU, Victor; SIDORENKO, Anatol; VRABII, Daniel (Editura Academiei Romane, 2016)
    Strokes are an acute neurological disorder resulting from blockage of blood supply to an area of the brain or cerebral hemorrhage. Strokes are a clinical syndrome produced by brain tissue damage following ischemic events. ...
  • URSACHI, Elena (Universitatea Tehnică a Moldovei, 2021)
    The development of technologies in recent years has led to the evolution of the fashion industry. 3d modeling is a new stage and will allow the preview of the final product. There are many reasons to move from paper and ...
  • ANDRONIC, Silvia (Academy of Sciences of Moldova, 2015)
    The Peierls structural transition in quasi-one-dimensional (Q1D) TTF-TCNQ organic crystals of is studied in the 3D approximation. Two the most important electron-phonon interactions are considered. The analytic expression ...

    In this work, the one-step three-dimensional (3D) printing of 20 nm nanowire (NW)-covered CuO/Cu2O/Cu microparticles (MPs) with diameters of 15–25 μm on the surface of the glass substrate forming an ordered net is successfully ...
  • FOGEL, Nina Ya.; CHERKASOVA, V. G.; RYBALCHENKO, V. N.; KORETZKAYA, O. A.; SIDORENKO, A. S. (Springer Nature Switzerland, 1996)
    Two-dimensional and three-dimensional vortex-lattice melting is observed on superconducting Mo/Si multilayers. Quasi-2D melting takes place in the range of high magnetic fields. The position of the melting transition on ...
  • SCHUR, J.; BIBER, S.; COJOCARI, O.; SCHMIDT, L.-P.; HARTNAGEL, H.-L. (IEEE, 2013)
    In this paper we present measurement results of a micro-machined split-block waveguide mixer for 600 GHz. The mixer implements a planar GaAs Schottky diode on a quartz substrate. Two different diode designs used for this ...
  • GIBSON, Hugh J.; COJOCARI, Oleg; OPREA, Ion; THOMAS, Bertrand; NARHI, Tapani (Oxford, 2015)
    Several recent space missions have required un-cooled receivers for radiometer use above 500GHz for atmosphere probing. These include MetOP 2nd generation meteorological satellites and Jupiter Moons JUICE spacecraft. The ...
