One of the most important elements of the bridge, from which the service life of this structure directly depends, is the supporting part. It provides the movement and rotation of span structures, as well as the transfer of all loads from the forces acting on them to the supports. The task of the designer is to select such support parts, that could be allowed maximum reducing of the forces, acting at the ends of the beams and having a minimum resistance to their free movement. It is necessary in each case to select the support part, which will most closely meet the requirements. To solve this problem, the author structured and tabulated the kinds of support parts. And also an analysis of the main characteristics of some of them.

Currently, counterfeit goods began dating in all types of consumer goods. The sector of textile products is one of the most susceptible to counterfeiting. A lot of companies confronted with the problem of counterfeiting of their products on a commercial scale. One of the promising directions in the area of protection against counterfeiting of products is the use of RFID technology. On the basis of one of the basic RFID standards established technology NFC, electronics manufacturers inserted into the smartphones the corresponding module. Using NFC technology, together with the developed system for the identification of products can serve as additional, and for some companies and the only protection against forgery.Each item in the system has a unique QR-code link to the page containing detailed information. Link consists of a website address and a unique identifier. The resulting QR-code may be printed on the label of the product, which is integrated with the NFC tag containing the same unique identifier. QR-code reading is carried out by appropriate application. NFC tag reading is possible if the corresponding module, which is now present in most mobile devices. The owner of a mobile device, comparing the received code, be able to distinguish original products from counterfeits.
