Theoretical prerequisites for substantiating the parameters of a rotary ripper for interrow potato cultivation

The article is devoted to the study of the process of interaction of the rotary ripper’s working bodies with the soil. The classification of rotary machines and implements according to the energy transmitted to the working body and the location of the rotation axis is outlined. The article notes that the main characteristics of the rotor work body motion are the trajectory type, the magnitude and direction of velocity of its most characteristic point, and in some cases, the magnitude and direction of acceleration. The article presents the results of theoretical research in the field of kinematics of interaction of rotary working tools with the soil. The design of the rotary ripper is presented and the description of the trajectory of its working bodies is made, the value of movement of the scraper plate in the contact area with the soil is established. We analyzed the segment of the path from the beginning of contact with the soil (the beginning of dragging the surface layer of soil) and the end of contact (the end of dragging the surface layer of soil), on the line of which weed combing, loosening and destruction of soil crust occurs

Радионуклидная визуализация молочной железы с использованием специализированной гаммакамеры высокого разрешения CZT в диагностике и оценке эффективности лечения больных раком молочной железы (обзор литературы)

Breast Specific Gamma Imaging (BSGI) or Molecular Breast Imaging (MBI) is a highly sensitive and specific diagnostic method in activity assessment of pathological lesion including breast cancer and its metastases. Not being a competitor to X-ray mammography this technology provides more information in case of patients with dense breast glandular tissue and it can also be an additional diagnostic method in the algorithm of early diagnosis of breast cancer.Планарная маммосцинтиграфия по методике Breast Specific Gamma Imaging (BSGI) является высокочувствительным и специфичным методом диагностики активности патологического очага, в том числе первичного рака молочной железы и его метастазов. Не являясь конкурентом рентгеновской маммографии, технология позволяет получить дополнительную информацию при плотной железистой ткани и может служить дополнительным диагностическим методом в алгоритме ранней диагностики рака молочной железы

Influence of Tests Results on Serial Production of EXFEL Superconducting Cavities

The European XFEL (EXFEL) 1.3 GHz cavities were produced without any final cold RF performance guarantee for characteristics like accelerating gradient, quality factor or field emission. In the case of low-performance, DESY provided all re-treatment procedures in order to improve these characteristics getting closer to specification levels. But EXFEL cavities have very tight tolerances for the parameters like cavity length, cells eccentricity, fundamental mode frequency and field distribution on the operational mode. Usage of modern infrastructure, analytical methods and powerful tools of the database analysis allows us not only keeping these characteristics in specified ranges, but also investigate the cavity shape uncertainties and improve the damping of the higher order modes

Legal Status of an Arbitral Institution in the Arbitral Process in Italy

The role of an arbitral institution in the arbitration process in Italy has been analyzed at the present study. Statutory regulation of creation and legal status of the institutions and contractual nature of their powers and obligations have been examined. Statutory regulation of functioning of the institutions and the legal status of their founding subjects has been briefly outlined. The main types of arbitral institutions have been exposed

Both in signals and images, each element of the data array t 2 T is naturally associated with a number of its neighbors. It is convenient to express the neighborhood relation in the form of an undirected graph G which is understood as set of pairs of neighboring elements G ae T \Theta T . Th

ANALYSIS LAYER MODEL OF POLYMER COMPOSITE DESIGN UNDER MULTIFACTOR LOADING

A mathematical model is offered for the analysis of complex stress-strain state of the layer load-carrying structures of the aircraft planes. It is presented as sets of the equations of the constraining relations of load parameters, voltages and deformation. The complex multilayered solution method that allows including specific features of the design geometry and behaviour of structural materials through multifactor loading is used for the solution of the systems of the equations
