Slaying the Jurisprudential Beast: Virginia's Flawed Multi-Factor Approach to Differentiating Ordinary Building Materials from Equipment and Machinery under Code Sec. 8.01-250

Gypsum Co., Virginia courts have assembled a multi-factor test to distinguish the term of art, "ordinary building materials," from "equipment" or "machinery." This Comment argues that this sprawling and ... -establishedclassification system of improvements to realproperty, the courts would apply common-sense notions of "ordinary building materials" and "equipment" rather than the current multi-factoranalysis. This construction

Applications of Microwave Materials: A Review

The performance of microwave devices mainly depends on the properties of materials used in the fabrication. Knowledge of material properties at microwave frequencies is a prerequisite to select ... frequencies is a prerequisite to select suitable materials for various microwave applications and vice versa.
