WASHINGTON (AP) — Democrats promised Thursday to speed an economic recovery package through Congress, but vowed to rearrange President Bush’s budget proposal to ben­ efit m iddle-income Americans, not the rich. “ Democrats w ill not obstruct, but we w ill try to improve the p re s id e n t’s p acka ge ,” sa id House Majority Leader Richard Gephardt, D-Mo., as the Budget Committee began hearings...

Recent lattice data indicates that volume occupied by topological fermionic modes shrinks to zero in the continuum limit of vanishing lattice spacing. The data apparently cannot be accommodated within, say, conventional instanton model. We review field-theoretic arguments which demonstrate that the topological fermionic modes are to shrink to a vanishing submanifold of the whole four dimensiona...

We study the form factor of thermoresponsive microgels based on poly(N-isopropylacrylamide) at high generalized volume fractions, ζ, where the particles must shrink or interpenetrate to fit into the available space. Small-angle neutron scattering with contrast matching techniques is used to determine the particle form factor. We find that the particle size is constant up to a volume fraction ro...

Porosity is a major problem occurring in aluminium alloy casting. During the process of solidification, alloy would shrink and emit dissolving hydrogen causing porosity formation inside the solidified part which leads to mechanical properties degradation. This research aims to produce a formula to explain the resulting porosity with the initial chemical compositions and cooling rate. A mathemat...
