ABSTRACTLayered structures can possess a high volumetric density of interfaces, which can result in novel magnetic properties. We report magnetic characteristics of two types of atomically layered structures, (001) oriented intermetallics with the CuAu(I) crystal structure and (111) oriented artificial multilayers. C-axis oriented superlattices of PtFe, PtCo, PdFe and PdCo with the layered CuAu(I) structure, possess large magnetic anisotropies and novel magneto-optic properties relative to the corresponding random alloys. These films are produced by annealing, with tetragonality and magnetic anisotropy developing in a fashion which depends on the initial bilayer period and annealing parameters. (111) oriented artificially grown Pd/CoCr multilayers are reported for perpendicular magnetic recording applications. Using a perpendicular contact probe transducer, the multilayers exhibit two times the readback signal of CoCr media. The multilayers can be made with low roughness suitable for contact recording, and can generate narrow readback pulses with large amplitude. Many aspects of Pd/Co performance, such as overwrite, can be predictably optimized for a given set of transducer properties. The reported results show that compositionally modulated structures can be made which have a wide variety of useful properties for perpendicular hard disk and magneto-optic recording.

The aim of the study was to evaluate the role of poikilocytosis in the acne vulgaris comorbidity with demodicosis and functional gallbladder disorder. Materials and methods: The study included 140 people with a diagnosis of moderate acne: group 1 – patients with AV, group 2 – patients with AV + Demodicosis, group 3- AV + Demodicosis + functional gallbladder disorder (FGD). Biochemical analysis of lipid profile and liver enzymes, bilirubin was performed with semi-automatic analyzer HUMALYZER 3000. Scanning electron microscopy was performed using scanning electron microscope PEI-106I “SELMI”. Ultrasound investigation was carried out by the SonoScape S6Pro US-diagnostic system with 3 – 5 MHz Ultrasound Probe Transducer С354. Results: The most significant changes in blood erythrocytes morphology were observed in patients with comorbidity of acne, demodicosis and FGD with highest increasing of deformed erythrocytes up to 21%, mainly due to echinocytes І, ІІ order. Correlation analysis has revealed a strong direct association r = +0.75 (p < 0.05) between the poikilocytosis and comorbidity of acne vulgaris with demodicosis and FGD. Conclusions: A strong direct association between acne vulgaris comorbid pathology and the increased number of deformation shapes of erythrocytes confirms the impact of FGD on morphological characteristics of erythrocytes and developing of poikilocytosis.
