Abstract Aim of the present work focuses with influence processing parameters on fabricated composites LM25 alloy SiC particles reinforcement through squeeze casting technique. The following process like stirring speed from 550 to 750 rpm, weight proportions 4 8% and melting temperature 600 700oC were employed. Then processed subjected microstructural analysis mechanical tests ascertain metallu...

Many natural materials demonstrate ideal design inspirations for the development of lightweight composite with excellent damage tolerance. One notable example is layered architecture nacre, which possesses toughness an order magnitude higher than its constituent parts. Man-made nacre-like ceramic/polymer composites obtained through direct infiltration polymer in ceramic scaffolds have been show...

Abstract This study emphasis on a novel fabrication technique to fabricate hybrid cermets using Al 6061 alloy with nano sized SiC, 2 O 3 and TiO as reinforcements. During the process, melted pool was ultrasonicated disperse nanoparticles at 20 kHz for 5 min pressure of 50 MPa applied eliminate voids. The influence physical, thermal mechanical properties were evaluated by tensile, wear studies. ...

We present a simple three-class model in the Kaleckian tradition to investigate the implications of a dominant managerial class class for the dynamics of demand and distribution. Managers are hired by capitalists to supervise workers, but supervision results in surplus extraction and wage inequality. The adjustment of capacity utilization to accommodate goods market disequilibrium produces two ...

The diffraction limit sets the smallest achievable linewidth at half the wavelength. With a subwavelength plasmonic lens allowing one to reduce the diffraction via an asymmetry and to generate and squeeze the wave functions, an incident light is focused by the aperture to a single line with its width smaller than the limited value in the intermediate zone. The focused fields are capable of prop...

This paper examines minority squeeze-outs and their regulation in Germany, a country where majority shareholders have extensively used this tool since its introduction in 2002. Using unique data on court rulings and compensations, we analyze a sample of 324 squeeze-outs of publicly listed companies from 2002 to 2011. Large firms with foreign large shareholders are the most likely to be delisted...

Ten right-handed patients with Parkinson's disease and 9 normal subjects performed five different types of movements as rapidly as possible in their own time: isotonic elbow flexion through an angle of 15 deg ('flex'); isometric squeezing of a force transducer between thumb and fingers ('squeeze'); isotonic finger flexion ('cut'); simultaneous performance of both 'flex' and 'squeeze'; simultane...
