The article about The theoretical basis for the development of new types of tool materials was the tendency to periodically update the working relief of the grinding surface- implementation of the elastic-relaxation mechanism of resistance to dynamic loads and ensuring self-sharpening of the tool due to plasticity and moderate mechanical strength of PTFE combined with elastic-deformation properties of diamond particles of natural origin.

This review attempts to see if listening systems are compelling to impact listening appreciation and the significant objective of the review is to uncover whether pre-tuning in, whilelistening and post-listening exercises are the most critical to interpret the primary thought of a listening text. It has been discovered that while-listening questions assume the significant part in cognizance of listening materials.

Scientific and technological progress, production efficiency in many spheres of the national economy is determined by the level of development of machinery by a key branch of the economy. Complex mechanization and automation, advanced technology, new materials with improved characteristics allow us to increase the technical level, resource and reliability of equipment, accelerate the production of new generations of machines and equipment.

The solution to the problem is to increase the service life before major repairs of the main types of machines, equipment and appliances, reducing their metal consumption, reduction of the number of workers engaged in repairs, energy storage, materials, increased productivity, environmental friendliness and safety depends on increasing the wear resistance and reliability of friction units.

Innovation and mechanical instruments assume a critical part in the creating scene in different viewpoints. PCs and language instructing have joined as indistinguishable marvel for years and years and innovation has become fundamental piece of educating and learning device in the language study hall. In unknown dialect instructing and learning measure, we can profit from such innovative devices as television, Radio, PCs, The web, Disc player, Sound Tapes, Electronic Word reference, Cell phones, Force point recordings, Skype, diverse informal organizations and DVDs. Web access and programming programs have facilitated in numerous parts of our lives, just as our instructive life. Inferable from innovative apparatuses, Students learn and get things speedier and simpler than any time in recent memory because of the utilization of mechanical gadgets.
