    In article at pregnant mares Oryol, Russian-rysistoj and thoroughbred riding English breeds and the foals received from them modern results of researches of an indicator of erythrocyte sedimentation rate are presented to the colostrums, dairy period and after branch from mothers at a diet on cultural pastures and during the winter stall period, at feeding by the hay prepared on cultural pastures. ESR in blood of mares by the pregnancy end decreases, and with approach of new pregnancy and a lactation starts to raise and remains till 7-8 months of pregnancy at identical level. At foals after branch from mothers and full transition to a vegetative diet ESR is accelerated to the top sizes of physiological norm. ESR at mares of thoroughbred riding English breed, in comparison with Oryol and Russian-rysistoj, is accelerated in connection with acclimatization to new conditions of the North Ossetia of foothills of Caucasus.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдставлСны Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ исслСдований показатСля скорости осСдания эритроцитов (БОЭ) Ρƒ ΠΆΠ΅Ρ€Π΅Π±Ρ‹Ρ… ΠΊΠΎΠ±Ρ‹Π» орловской, русско-рысистой ΠΈ чистокровной Π²Π΅Ρ€Ρ…ΠΎΠ²ΠΎΠΉ английской ΠΏΠΎΡ€ΠΎΠ΄; Ρƒ ΠΏΠΎΠ»ΡƒΡ‡Π΅Π½Π½Ρ‹Ρ… ΠΎΡ‚ Π½ΠΈΡ… ТСрСбят: Π² ΠΌΠΎΠ»ΠΎΠ·ΠΈΠ²Π½Ρ‹ΠΉ ΠΈ ΠΌΠΎΠ»ΠΎΡ‡Π½Ρ‹ΠΉ ΠΏΠ΅Ρ€ΠΈΠΎΠ΄ ΠΈ послС ΠΎΡ‚ΡŠΠ΅ΠΌΠ° ΠΎΡ‚ ΠΌΠ°Ρ‚Π΅Ρ€Π΅ΠΉ (ΠΏΡ€ΠΈ ΠΏΠ°ΡΡ‚ΡŒΠ±Π΅ Π½Π° ΠΊΡƒΠ»ΡŒΡ‚ΡƒΡ€Π½Ρ‹Ρ… Π·Π°Π³ΠΎΠ½Π½Ρ‹Ρ… Π»Π΅Π²Π°Π΄Π°Ρ… ΠΈ Π² Π·ΠΈΠΌΠ½ΠΈΠΉ стойловый ΠΏΠ΅Ρ€ΠΈΠΎΠ΄ - ΠΏΡ€ΠΈ ΠΊΠΎΡ€ΠΌΠ»Π΅Π½ΠΈΠΈ сСном, Π·Π°Π³ΠΎΡ‚ΠΎΠ²Π»Π΅Π½Π½Ρ‹ΠΌ Π½Π° Π»Π΅Π²Π°Π΄Π°Ρ…).

    Investigation of a linear variable optical filter (LVOF) manufacturing process

    Get PDF
    This paper reports on fabrication process for Linear Variable Optical Filters (LVOF). This LVOF can be fabricated in a resist layer by just one lithography step. The profile of resist structure is subsequently transferred into quartz substrate by plasma etching. Complete LVOF fabrication involves deposition of a lower dielectric mirror using a stack of dielectrics on the substrate, tapered layer formation and deposition of the top dielectric mirror [1]. Shown possibility of LVOF using in experimental hyperspectral setups

    Controlling the orbital angular momentum of Gaussian vortices by shifting the point of phase singularity

    Get PDF
    A simple formula is obtained to describe the normalized orbital angular momentum (OAM) of a Gaussian beam after passing through a shifter spiral phase plate (SPP). The formula shows that while being equal to the topological charge at the zero off-axis shift, the OAM becomes fractional with increasing shift and it is tending to zero exponentially. Analytic expressions of the complex amplitude of the Gaussian beam having passed through the off-axis SPP show that as the beam propagates, the isolated intensity null moves from the initial point defined by the vector of the SPP's center shift along a straight line perpendicular to the said vector. Using a liquid crystal light modulator, crescent-shaped beams are experimentally generated.This work was supported by the Federal Agency of Scientific Organizations (agreement No 007-Π“Π—/Π§3363/26) and funded by the Russian Science Foundation (RSF), grant No. 17-19-01186

    Analysis of dielectric circular cylinder light spot narrowing by whispering gallery modes and influence of material absorption

    We present results of numerical analysis of the diffraction of a plane monochromatic TE-wave on an ideal homogeneous dielectric cylinder with several resonant wavelength scale radii. Two subsequent near-surface maxima of intensity (two focuses) generated at the cylinder output were found on the optical axis. The first subwavelength focus is formed by one of the whispering gallery mode lobes. Its intensity is 50 times the incident light intensity and its full width at the half maximum of the intensity is equal to 0.155 of the incident wavelength. The second focus is two times less in intensity. Its focal spot known as a photonic nanojet is stretched toward the optical axis. The second focus is formed at a distance about the wavelength from the cylinder surface. Its width is equal to 0.44 of the wavelength and its length is two wavelengths. The influence of material absorption on the light focusing is also examined by numerical simulation.This work was supported by the Federal Agency of Scientific Organizations (agreement No 007-Π“Π—/Π§3363/26) and the Ministry of Education and Science of the Russian Federation (# SP-4375.2016.5), a RF Presidential grants for support of leading scientific schools (NSh-6307.2018.8) and young candidate of science (MK-9019.2016.2),and the Russian Foundation for Basic Research (##17-47-630420, 17-47-630417, 16-47-630483, 15-07-01174)
