A brief overview of methods for cutting round bars and pipes is presented, their main advantages, disadvantages field application are considered. It proposed to use the effect fatigue fracture breaking. The task study this process under action cyclic loads. possibility applying known provisions calculating theory strength analysis low-cycle tested. comparative assessment theoretical experimenta...

the new non-conventional cutting process by the use of thermal shock is a convenient procedure for cutting the brittle materials such as glasses and ceramics. this method is based on the application of localized thermal shock to brittle materials by the use of hot air jet, which induces thermal stresses at the tip of an existed pre-crack. due to the thermo-elastic behavior of materials, the pre...

The material removal rate (MRR) plays a critical role in the chemical mechanical planarization (CMP) process semiconductor industry. Many physics-based and data-driven approaches have been proposed to-date to predict MRR. Nevertheless, most of them neglect underlying equipment structure containing essential interaction mechanisms among different components. To fill gap, this paper proposes nove...

Grinding of various materials is carried out in ways: cutting, crushing, sawing, breaking, hitting.
 In the technological equipment meat processing plants, grinding achieved by a combination several types mechanical action. Each type characterized an average particle size, while large, medium, fine, ultrafine (colloidal grinding) used.
 A block diagram and products has been compiled, ...

Various surgical approaches and methods of hemostasis have been reported for intraabdominal ligation and hemostasis in equine MIS. In recent years laparoscopic approaches have become popular in light of the fact that they are minimally invasive, provide superior visualization, allow tension free hemostasis, and eliminate the need for general anesthesia. Laparoscopic techniques described for lig...

Wireless sensor networks (WSN) have become a significant technology in recent years. They can be widely used in many applications. WSNs consist of a large number of sensor nodes and each of them is energy-constrained and low-power dissipation. Most of the sensor nodes are tiny sensors with small memories and do not acquire their own locations. This means determining the locations of the unknown...

Manual harvesting has predominated in the South African sugar industry since 1948, when sugarcane was first cropped at Compensation on the north coast of KwaZulu-Natal. However, as successive generations of labour have attained higher levels of education and their living standards have improved, employment aspirations have risen above the strenous but monotonous hand cutting of sugarcane, and t...

Silicosis is a fibrotic disease of the lungs caused by inhalation, retention, and pulmonary reaction to crystalline silica. Crystalline silica exposure is widespread, and silica sand is an inexpensive and versatile component of many manufacturing processes. Its use and the incidence of silicosis are increased in industrial operations by the mechanization and the use of sandblasting, drilling, p...

The methods of molecular biology allow for analyzing the methylation pattern in the whole genome and in particular genes. We differentiate methylated sequences from unmethylated ones by means of cutting the genomic template with methylation-sensitive restriction enzymes or by sodium bisulfite DNA modification. Chemical modification precedes most quantitative and qualitative PCR techniques: MS-P...
