Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to orthodontics. Inter-root and inter-coronary measurements are performed before and after expansion. Above measurements are performed on the upper jaw model representing an upper jaw digital model superimposed by an oral scanning of the dentition and a computer tomogram. Then value of expansion of upper jaw is determined by crowns and by teeth roots in millimetres, where ΔX is an extension of teeth crowns in millimetres, ΔY is an extension of tooth roots in millimetres. If ΔX ≠ 0 and ΔY = 0, inclined nature of teeth displacement is determined. If ΔY ≠ 0, CAI - crown-apical index is calculated using formula CAI = ΔX/ΔY. If CAI value = 1, the corporal nature of teeth displacement is determined as a result of upper jaw expansion. In the CAI ≠ 1, the tooth displacement pattern is determined as being inclined-translational. In this case, the change in the dental implantation is determined by calculating the difference in the angles formed by the longitudinal axis of the tooth and perpendicular lowered on occlusal plane from root apex, before expansion and after expansion of upper jaw. After that, the obtained value is compared between the same teeth of the left and right dentitions, if observing the differences between them, the asymmetry of the teeth movement is determined with the expansion of the upper jaw. 
     EFFECT: method enables assessing the nature of movement of canines, premolars and molars, improving accuracy of arrangement of cephalometric points, assessing the effectiveness of the mechanics of operation of the applied distraction apparatus and the expansion results of the upper jaw without using absolute values.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to surgery, traumatology and orthopedics, and can be used in stage treatment of patients with chronic recurrent periprosthetic hip infection caused by microbial pathogens with high resistance to antibiotics. Method involves a two-stage complex surgical treatment, wherein at the first stage after removal of all previously installed orthopedic structures and materials, including bone cement, a radical surgical treatment of the periprosthetic infection focus is performed. Bone tissue affected by osteomyelitis process is removed, and compromised surrounding soft tissues are excised. Formed tissue cavity is then filled by non-free transplantation of an islet flap from the lateral broad muscle of thigh. This island muscular flap is moved on a constant vascular pedicle including a descending branch of the lateral envelope of the femoral artery and accompanying similar veins. Postoperative period involves an antibiotic course of at least 8 weeks. Further, in the patients with long-term remission of the infectious process, a second stage of surgical management, revision replacement surgery, is performed not earlier than 12 months after the first operation. In postoperative period repeated course of antibiotic therapy for at least 8 weeks. 
     EFFECT: method provides higher clinical effectiveness and possibility of further recovery of lower extremity support ability by means of revision hip replacement due to absence of foreign body infection, which can serve as a basis for microbial biofilm formation, as well as good blood supply of an islet muscular flap replacing the cavity in the region of the hip joint formed during radical surgical treatment.

Abstract: FIELD: telecommunications. 
     SUBSTANCE: to realise the described result, a method for telecommunications is proposed for achieving potential productivity, interference resistance, and speed of connection, consisting in the fact that in case of errors in analogue communication channels the information is transmitted in portions. Located in front of the portion is the header - pilot signal - followed by the body of the portion. The body of the portion is formed by a first convolution, wherein reduced copies of the pilot signal are used as said convolution. The formed portion is then read into the communication channel at the maximum permissible speed. At the output of the communication channel, the following tasks are performed using a synchroniser on AS-transformation: a portion is detected and divided into a header and a body; a first scan of the header and the body of the portion is performed, returning the inaccurate information with errors; a second scan is performed, returning distortion and interference; the result of the second scan is subtracted from the result of the first scan.

Abstract: Предложенное изобретение относится к дозирующему оборудованию и может быть использовано для подачи различных сыпучих материалов в сельскохозяйственной, лесной, семяобрабатывающей технике с целью их разделения на фракции. Устройство для подачи сыпучего материала содержит треугольный бункер, выполненный с возможностью регулировки угла его наклона, вращающиеся ролики, установленные на корпусе, подающую заслонку, выполненную с возможностью регулировки угла ее наклона, 3 пары регулирующих поток сыпучего материала заслонок, зазоры между которыми определяют подачу сыпучего материала на вращающиеся ролики устройства. Степень открытия подающей заслонки обеспечивает определенный зазор между подающей заслонкой и дном треугольного бункера, который создает поток сыпучего материала. Три пары регулирующих поток сыпучего материала заслонок выполнены саморегулируемыми с возможностью изменения угла их схождения-расхождения с помощью оттарированных пружин, имеющих разные коэффициенты упругости, а следовательно, и разное усилие растяжения. Оттарированные пружины средних саморегулируемых заслонок имеют меньшее усилие растяжения по сравнению с оттарированными пружинами верхних саморегулируемых заслонок и большее - по сравнению с оттарированными пружинами нижних саморегулируемых заслонок, в результате чего перед верхними саморегулируемыми заслонками накапливается наибольшая масса сыпучего материала, а перед нижними саморегулируемыми заслонками - наименьшая, чем обеспечивается саморегулирование и равномерное прохождение потока сыпучего материала.

     SUBSTANCE: invention relates to methods for protecting products from counterfeiting and is intended to determine the authenticity of products using technical means. A protective agent is formed on the product by applying on it at least one control mark containing nanosized cellulose particles, metal nanoparticles with a particle size of 15 to 100 nm, selected from the group: gold nanoparticles, silver nanoparticles, nanoparticles of an alloy of gold and silver, nanoparticles consisting of a gold core and a silver shell, nanoparticles consisting of a silver core and a gold shell, mixtures of any of these nanoparticles, and exhibiting the properties of surface plasmon resonance at a wavelength selected from the range from 400 to 2000 nm, at least two coding organic substances previously adsorbed on metal nanoparticles, related to Lewis bases, having high polarizability and characterized by different Raman spectra and a protective additive having the property of photoluminescence or elastic light scattering when irradiated at a wavelength in the range from 400 to 2000 nm, which differs from the wavelength of the surface plasmon resonance of the metal nanoparticles used. Each control mark with a certain quantitative composition is assigned to a certain specific symbol and a combination of symbols with a given sequence is formed, corresponding to the designation of the item under test. Then, after the operation of the product, the control marks are read by their irradiation with monochromatic electromagnetic radiation at the wavelength of the surface plasmon resonance of the metal nanoparticles used with simultaneous registration of the giant Raman spectra of each of the applied control marks, by which their quantitative compositions are determined. The latter are compares with the quantitative compositions of the applied control marks corresponding to specific symbols. Then the correspondence of the received sequence of symbols with the designation of the item under test is checked, and if the received sequence of characters coincides with the designation of the item under test, a conclusion is made about the authenticity of the item under test. 
     EFFECT: invention ensures the stability of protection over time, protecting control marks from wear and contamination during the operation of products, increases the number of evaluative features by optimizing the composition of the protective agent applied to the product, while reduces the possibility of counterfeiting, copying and changing.
