A board-to board electrical connector assembly is provided for effecting a connection between two circuit boards. proprietary inbred maize varieties. The stator core is formed as a near-net-shape compact by an electromagnetic pressing process and has an as-formed density of at least about 98% of the theoretical density. The ends of the barrel portion are machined as desired for flushness. The resource block conversion unit converts the resource block allocation method for the resource block allocation information when the conversion is possible. The present invention provides a plant nutrition formulation including steps of providing a culture solution containing a culture medium, a non-woody fiber plant material and microbial suspension, fermenting the culture solution for preparing a biopulping solution, filtrating the biopulping solution for preparing a filtrate, and formulating the filtrate for preparing a plant nutrition.
