    ANOMALOUS SCALING OF THE PASSIVE SCALAR

    Full text link
    We establish anomalous inertial range scaling of structure functions for a model of advection of a passive scalar by a random velocity field. The velocity statistics is taken gaussian with decorrelation in time and velocity differences scaling as ∣x∣κ/2|x|^{\kappa/2} in space, with 0≀κ<20\leq\kappa < 2. The scalar is driven by a gaussian forcing acting on spatial scale LL and decorrelated in time. The structure functions for the scalar are well defined as the diffusivity is taken to zero and acquire anomalous scaling behavior for large pumping scales LL. The anomalous exponent is calculated explicitly for the 4^{\m\rm th} structure function and for small ΞΊ\kappa and it differs from previous predictions. For all but the second structure functions the anomalous exponents are nonvanishing.Comment: 8 pages, late

    The authors characterized a heterogeneous group of a rare disease - Langerhans and non-Langerhans cell histiocytosis, and analyzed key differential and diagnostic differences between these forms of the disease. A very rare case of non- Langerhans cell histiocytosis (Rosai-Dorfman disease) in a female patient aged 63 with the subsequent spontaneous regression of eruptions was described. Key skin manifestations of the Rosai-Dorfman disease included papular eruptions of the typical intense pink color with a yellowish and brown tint. Morphologic changes were characterized by proliferation of histiocytes and accumulation of different lipids and pentalamellar markers (S-100 protein, Π‘D 14, Π‘D 68, lysozyme) in their cytoplasm. Though the Rosai-Dorfman disease usually involves lymph nodes, this case was characterized by unaffected nodular structures.ΠžΡ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΠΎΠ²Π°Π½Π° нСоднородная Π³Ρ€ΡƒΠΏΠΏΠ° Ρ€Π΅Π΄ΠΊΠΈΡ… гистиоцитозов лангСргансового ΠΈ нСлангСргансового Ρ‚ΠΈΠΏΠΎΠ²; ΠΏΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Ρ‹ ΠΈΡ… основныС Π΄ΠΈΡ„Ρ„Π΅Ρ€Π΅Π½Ρ†ΠΈΠ°Π»ΡŒΠ½ΠΎ-диагностичСскиС различия.

    The article presents a literature review and case study of a rare form of dermatitis in a female patient aged 61 - Kyrle disease (hyperkeratosis follicularis et parafollicularis in cutem penetrans). It also provides a detailed description of the clinical picture and differential diagnostics of the disease. The following typical changes were observed based on the results of histological examination: epidermic invaginations filled with corneous masses and areas of focal parakeratosis. Essential improvement in skin process dynamics was achieved against the background of treatment with Acitretin.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½Ρ‹ Π°Π½Π°Π»ΠΈΠ· Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹ ΠΈ описаниС наблюдСния ΠΊΡ€Π°ΠΉΠ½Π΅ Ρ€Π΅Π΄ΠΊΠΎΠ³ΠΎ Π΄Π΅Ρ€ΠΌΠ°Ρ‚ΠΎΠ·Π° - Π±ΠΎΠ»Π΅Π·Π½ΠΈ ΠšΠΈΡ€Π»Π΅ (ΠΊΠ΅Ρ€Π°Ρ‚ΠΎΠ· фолликулярный ΠΈ парафолликулярный, ΠΏΡ€ΠΎΠ½ΠΈΠΊΠ°ΡŽΡ‰ΠΈΠΉ Π² ΠΊΠΎΠΆΡƒ) Ρƒ больной 61 Π³ΠΎΠ΄Π°.
