New specimens of the problematic group Sphenothallus have been recovered from the early Cambrian Shuijingtuo and Niutitang Formations in South China. The two sites from the Shuijingtuo Formation were collected from Yanjiahe ...

Seston is the complex of organic and inorganic particles suspended in the water column in stream ecosystems. This detrital pool is a significant vector of energy and nutrients from headwaters to the ocean. Many of the ...

Sandwich plates and layered composites are common in many structural applications because of their combination of high stiffness and low weight. These plates combine top and bottom layers of high Young's modulus with ...

The field of self-healing materials is growing dramatically due to the obvious in- centive of having structural materials with the ability to repair damage. Some polymers have demonstrated the ability to heal from damage ...

This thesis investigates the constancy of light speed with respect to the light age using an active fiber-based Mach-Zehnder interferometer (MZI) illuminated by sunlight. The original sunlight in one arm, which has the age ...

Welcome to the movies! Welcome to the stars! Welcome to this grand illusion! All of it's yours. New Urbanism. Hollywood thinks you're stupid. Scientology. Retro-futurism. Taking back color from toiletries. Personal politics. ...

In an ideal world, unwanted or undesirable effects in a system could and would be completely ignored. In fact, this was the case in mid-80s' PC design when an 80286 microprocessor running at a "blazing" 12 MHz was considered ...

Rhizoctonia zeae is a common pathogen of tall fescue and other turfgrasses in various regions of the United States. Disease caused by R. zeae typically occurs during hot, humid summer months when conditions are ideal for ...

Joining of uniformly-curved composite sandwich panel segments, typical in state of the art aerospace launch vehicles, should be mass-efficient. Adhesively bonded joints can provide increased mass-efficiency over ...
