FEA simulation of the huge indexing table for a multi-purpose machine tool is provided. Excessive corner flexibility of the initial design is revealed. A set of reinforcing design solutions is generated. Several combinations of cast iron ribs and polymer concrete inserts are analyzed. Corner rigidity is enhanced from 48.8 to 388.5 N/μm with table weight rising from 5.36 to 6.98 ...

Bionic solution for reinforcement of “travelling column” machine is developed. It concerns special project of old heavy precise machine redesign and renovation. It is proposed to attach tree-like polymer-concrete outer bandage to the flexible column. Bionic-shape vertical console is created. Design is proved by FEA simulation. Static rigidity is increased twice. Bending eigenmode ...

Based on the OBE concept and promoting education with science, this paper organically combines the drilling innovative test in metal processing with the mechanical professional knowledge, and expounds in detail the application of four-way piezoelectric drilling dynamometer in the transverse cutting vibration test of drill bit through the design of simulation test platform.

Analysis of the manufacturing of the part for the subsequent development of the forging drawing. Simulation in a CAE system with subsequent calculation of operation parameters. The choice of equipment based on the data obtained during modeling. Analysis of the results obtained and determination of the amount of metal saved.

With hypocalcemia, PTH synthesis is enhanced, which increases the osteolytic activity of osteoblasts and osteocytes, activating osteocytic osteolysis, stimulates the movement of osteoclasts to the site of resorption and their activity [1, 3]. With hypercalcemia, according to the feedback principle, the synthesis of calcitonin increases, which stimulates the flow of calcium and ...

The prevention and treatment post-burn deformation of foot is difficult practice. These interferences should be direct the firstly for prevention of rising pathologic scars.

In this article, questions were raised about the effectiveness of optimizing medical accounting records and the introduction of information systems that should help improve the quality of both medical care and accounting records. The above, in turn, should lead to a reduction in the time spent on filling out paper carriers in the activities of practicing doctors of medical organizations.

The paper presents questions on the use and production of matrix stents for peripheral and coronary arteries to restore the lumen of coronary and peripheral blood vessels by catheter balloon expansion. Materials for their creation and methods of obtaining these materials are considered.

We did not immediately switch from massive computers with numerous toggle switches to the use of modern computers, keyboards and computer mice - it took years, and now people all over the world use them daily and hourly. With the rapid development of technology, it's only a matter of time before the whole world enters a new era – the era of humanmachine interfaces.

ERCP includes many complex manipulations that require nervous and physical stress, both from the patient and from the examiners, therefore, the use of such a study is indicated only in cases where non-invasive diagnostic methods d not provide the necessary information about the state of the biliary tract and pancreas.
