One of the most important characteristics of annular arrays is their superior focal capabilities. In order to achieve the desired focussing, each of the elements is fired in different times. The delay times used for beam focussing are called focal laws. The focal laws are automatically calculated from the inspection software. In order to make sure that the focal laws are calculated correctly fr...

Modern production of structural parts in the aeronautic industry is characterized by mechanically optimized structures that can be complicated to inspect due to complex geometries and/or complex materials. Developing NDT procedures is thus more challenging and could become costly without tools to help NDT design and performance predictions. Simulation is a major asset to help engineers to evalu...

Traditional online wheel-set ultrasonic inspection method and inspection technology can not meet the new requirement of High Power Locomotive wheel-set online. In this article, features of locomotive wheel and defect distribution are analyzed, and a more strictly online inspection requirement is put forward. Based on which, an optimized multi arrangement of phased array and conventional ultraso...

Modern pig farming is a significant sector of modern agriculture in many countries. The attractiveness its products associated with their excellent taste and economic affordability. intensive development breeding considers the latest achievements field biology during early ontogenesis. Optimal functioning hemostasis growing piglets relies on platelet activity. Its low severity phase milk vegeta...

Both aging and chronic inflammation produce complex structural and biochemical alterations to the lung known to impact work of breathing. Mice deficient in surfactant protein D (Sftpd) develop progressive age-related lung pathology characterized by tissue destruction/remodeling, accumulation of foamy macrophages and alteration in surfactant composition. This study proposes to relate changes in ...

Aims: The variability in evolution of the novel coronavirus has perplexed medical community. We herein report case a patient with specific characteristics, somewhat outside reported average values.
 Presentation Case: A 60-year-old type I diabetic was admitted as an outpatient to university hospital for following symptoms: fever up 38.1˚C, malaise, and shortness breath. Upon admittance, ch...

efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted inrecent years. however, many basic questions have been ambiguous up until now. nanoparticlespenetrate into pore volume of porous media, stick on the core surface, and by creating homogeneouswater-wet area, cause to alter wettability. this work introduces the new concept of adding znonanoparticle...
