Kinematics of Spherical Milling Cutters Forming

© 2017 The Authors. Published by Elsevier Ltd. The mathematical relations between the helical surface on the sphere, the formlining, and the process of forming the spherical cutter by the disc-shaped tool are revealed. An algorithm and a program for calculating the spherical milling parameters based on kinematics of formation were developed, taking into account the kinematics of shaping, the determination of the profile of a disk tool for processing a spherical cutter. The effect of the parameters of the helical surface on the profile of the disk tool is investigated. To be able to integrate with other systems in the program, a system of inter-program data exchange - export of table of output variables in Microsoft Excel - was implemented

Tool creation and operation system development for large engineering enterprises

On the basis of JSC "KAMAZ", the article describes a new concept of the automated tool creation and operation (TCO) system with tool identification at all stages of the life cycle with the possibility of adaptation to any machine-building enterprise. Russian machine-building companies have traditionally made over 80% of the tool themself. Therefore, the concept of TCO system is wider than adopted in the European countries Tool management (TM) concept. A general structure of the classification is developed for all kinds of tool manufacture. The system allows the assignment of a unique code to each tool. This permits to create the preconditions for the development of subsystems of its purchasing, design, production and operation. © IDOSI Publications, 2014

Scientific - industrial aspects of integration product lifecycle management and enterprise resource planning systems

The developed module will provide a dynamic implementation of the integration information systems such as product lifecycle management (PLM), enterprise resource planning (ERP) and others of the enterprise through the use of intelligent agents and knowledge based on experience and rules. Integration module is independent of the software architecture of information systems, because it uses with the embedded integration solutions of different systems. It can work with two or more information systems using bidirectional data transmission scheme. The result will be to minimize errors by eliminating the human factor, the exclusion of manual labor and increase efficiency of decision making. © IDOSI Publications, 2013

Detection of macro-thyrotropinaemia in patients with Hashimotos thyroiditis and subclinical hypothyroidism

The level of thyroid stimulating hormone is one of the diagnostic indicators of thyroid function. In subclinical hypothyroidism, its concentration in the blood serum increases, while the level of thyroid hormones remains normal. One of the reasons for this is the phenomenon of macrotyrotropinemia, in which the macro isoforms of thyrotropin (a complex of thyrotropic hormone with immunoglobulin) are present in the blood. It is assumed that the biological activity of macrotyrotropin is low, and may accumulate in the circulation, causing a falsely elevated level of thyroid-stimulating hormone in serum. The aim of this study is to identify the nature and prevalence of the macrothyrotropinemia phenomenon among patients with subclinical hypothyroidism in presence of autoimmune thyroiditis and a group of healthy donors. Materials and methods: Fifty serum samples of venous blood served as the material for the study: 30 patients with subclinical hypothyroidism in presence of autoimmune thyroiditis; 10, with manifesting hypothyroidism, 10 conditionally healthy donors without thyroid gland pathology (control group). The group was derived from results of the clinical laboratory at the Clinical Hospital at the Kazan station railway. Patients’ blood serum was screened for the presence of macrotrorotropin by polyethylene glycol precipitation method, followed by analysis by gel filtration chromatography. Results of this study were as follows: screening of blood sera was performed by gel filtration and affinity chromatography. Polyethylene glycol was shown to precipitate 50 to 100% serum thyrotropin, of which true macrotrothropin makes 56-98%. In the patients with subclinical hypothyroidism with a thyroid-stimulating hormone level of more than 10 pIU/ml, a trend towards an increase in the level of macrothyrotrophinaemia has been shown. The content of macrotyrotropin complex in patients with subclinical hypothyroidism, in whom the level of antibodies to thyroperoxidase is > 500 U/L, is significantly higher if compared to the patients with manifesting hypothyroidism. Elevated levels of antibodies to thyroperoxidase can lead to the generation of macrotyropin. Our findings have shown that the phenomenon of macrothyrotropinemia is quite common in patients with subclinical and manifesting hypothyroidism with Hashimoto thyroiditis (53.3%) and in control group (25%). Macrotyrotropin complex probably consists of thyrotropin and IgG. Patients with a thyroid-stimulating hormone level of > 10 pIU/ml are candidates for screening for the presence of the macrotyrotropin complex.The activity of the autoimmune process may correlate with the phenomenon of macrothyrotropinemia. The results can be used to develop an additional tool when choosing therapy in clinical practice
