Metal matrix composites (MMCs) are attracting automobile and aeronautical sector because of their superior mechanical physical characteristics which ultimately reduce the weight components hence energy requirements. These prepared by adding various reinforcements into base metal methods like stir casting, squeeze sand in-setu method, powder metallurgy etc. When more than one particle is added m...

In the coming decades, world agricultural systems will face serious transitions. Population growth, income and lifestyle changes will lead to considerable increases in food demand. Moreover, a rising demand for renewable energy and biodiversity protection may restrict the area available for food production. On the other hand, global climate change will affect production conditions for better or...

Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...

We study an incentive model of financial intermediation in which firms as well as intermediaries are capital constrained. We analyze how the distribution of wealth across firms, intermediaries, and uninformed investors affects investment, interest rates, and the intensity of monitoring. We show that all forms of capital tightening (a credit crunch, a collateral squeeze, or a savings squeeze) hi...

This paper studies the nonlinear effects of squeeze film stiffening on the performance of a high resolution MEMS nonresonant inertial sensor. It is shown that these effects introduce a surprising dynamic response that extends the operational frequency range of the devices by retarding the resonate response. In addition, this performance advantage will occur without the traditional gain trade-of...

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an appropriate framework in the case of an unregulated firm, whereas a firm under tight wholesale regulation shou...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

China is facing a male marriage squeeze, as there are more men in the marriage market than potential female partners. As a consequence, some men may fail to ever marry. However, while some studies have suggested that most unmarried men affected by the marriage squeeze in rural China feel a sense of failure, the quality of life of the men who remain unmarried against their will remains largely u...
