The invention relates to transgenic plants exhibiting dramatically enhanced growth rates, greater seed and fruit/pod yields, earlier and more productive flowering, more efficient nitrogen utilization, increased tolerance to high salt conditions, and increased biomass yields. In one embodiment, transgenic plants engineered to over-express both glutamine phenylpyruvate transaminase (GPT) and glutamine synthetase (GS) are provided. The GPT+GS double-transgenic plants of the invention consistently exhibit enhanced growth characteristics, with T0 generation lines showing an increase in biomass over wild type counterparts of between 50% and 300%. Generations that result from sexual crosses and/or selfing typically perform even better, with some of the double-transgenic plants achieving an astounding four-fold biomass increase over wild type plants.

An adjustable lighting apparatus for illuminating a specimen while facilitating access to the specimen includes an elongated post defining a first axis, a hub movably attached to the post, and a pair of pivotable curved plate jaws, each jaw connected to the hub and configured for independent movement relative to the hub. The hub is configured for movement parallel to the first axis of the post. Each jaw of the pair of pivotable curved plate jaws has a concave interior surface and has one or more light sources positioned within or against the interior surface between a proximate jaw end and a distal jaw end for illuminating a specimen located within the expandable boundary.

Strong, light-weight composite laminates are made by impregnating layers of paper with a cellulose nanofiber (CNF) slurry, laying the coated papers up in a plurality of layers or stack, and subjecting the stack to pressure and heat for a period of time sufficient to cause the CNF to impregnate, reinforce, and bond the paper layers into a composite. The resulting composite has impressive mechanical strength and exhibits a substantially homogeneous composition throughout its depth. The composite should have good strength to weight properties, and be recyclable or compostable.

A scalable, energy efficient process for preparing cellulose nanofibers is disclosed. The process employs treating the cellulosic material with a first mechanical refiner with plates having a configuration of blades separated by grooves, and subsequently treating the material with a second mechanical refiner with plates having a configuration of blades separated by grooves different than the first refiner. The plate configurations and treatment operations are selected such that the first refiner produces a first SEL that is greater than the SEL of the second refiner, by as much as 2-50 fold. An exemplary high first SEL may be in the range of 1.5 to 8 J/m. Paper products made with about 2% to about 30% cellulose nanofibers having a length from about 0.2 mm to about 0.5 mm, preferably from 0.2 mm to about 0.4 mm have improved properties.

A wind turbine tower includes a plurality of tower sections axially aligned and connected together. Each tower section includes an inner wall having a tapered cylindrical shape concentrically positioned within an outer wall having a tapered cylindrical shape. An annular space is defined between the inner wall and the outer wall, and a layer of concrete is disposed within the annular space. A plurality of post-tensioning cables extend longitudinally within the annular space or outside the outer wall, such that a first one of the tower sections is connected to a second one of the tower sections by a plurality of the post-tensioning cables.
