Portable flooring protects finished surfaces, is easily moved

To protect curved, finished surface and provide support for workmen, portable flooring has been made from rigid plastic foam blocks, faced with aluminum strips. Held together by nylon webbing, the flooring can be rolled up for easy carrying

Honeycomb panel and method of making same Patent

Method for honeycomb panel bonding by thermosetting film adhesive with electrical heat mean

Flexible honeycomb structure can bend to fit compound curves

For flexibility in forming a curved surface, a honeycomb configuration using multiple pleats has proved superior to the usual core structures. The partial pleats formed in individual cell walls permit movements to and from the central axis without tearing

Borrowing Trouble: Should the FDA Regulate Human Cloning?

Less than a year after scientist Ian Wilmut announced the birth of Dolly, the world's first cloned sheep, entrepreneur and physicist Richard Seed stated on National Public Radio that he intended to establish a for-profit clinic to clone human beings as soon as the technology was available. An immediate, visceral reaction to the prospect of human cloning reverberated throughout the nation and the rest of the world, as private and public organizations alike rushed to impose moratoriums, pass legislation, and appeal to scientists' morality to suppress any attempts to clone a human being. In the thick of this debate it became apparent that no existing arm of the federal government had jurisdiction to monitor privately-funded research. The Food and Drug Administration (FDA) then stepped forward and asserted that it, in fact, did have authority to regulate human cloning under the Public Health Service Act and the Federal Food, Drug and Cosmetic Act. Since then the dust has settled. More than one legal scholar has questioned the FDA's claim to authority, and the FDA itself concedes to be re-evaluating its position. While legal scholars struggle to define the scope of the FDA's power, ethical scholars appear engaged in a debate over the moral implications of cloning a human. What these groups have failed to address satisfactorily, and what I intend to resolve, is how these two debates are intertwined and how they can be disentangled. While the bounds of FDA authority may appear no more complicated than any other academic legal question, I intend to show that by regulating human cloning the FDA necessarily takes a stand in the currently ongoing ethical debate in which it should remain neutral

Vacuum-type backup bar speeds weld repairs

A backup bar designed to use both vacuum and air pressure provides a method of sealing the weld root of a faulty section of seam weld. With slight redesign, the bar can be made sufficiently flexible to fit any large cylindrical surface

Genetic evidence of human adaptation to a cooked diet

Humans have been argued to be biologically adapted to a cooked diet, but this hypothesis has not been tested at the molecular level. Here, we combine controlled feeding experiments in mice with comparative primate genomics to show that consumption of a cooked diet influences gene expression and that affected genes bear signals of positive selection in the human lineage. Liver gene expression profiles in mice fed standardized diets of meat or tuber were affected by food type and cooking, but not by caloric intake or consumer energy balance. Genes affected by cooking were highly correlated with genes known to be differentially expressed in liver between humans and other primates, and more genes in this overlap set show signals of positive selection in humans than would be expected by chance. Sequence changes in the genes under selection appear before the split between modern humans and two archaic human groups, Neandertals and Denisovans, supporting the idea that human adaptation to a cooked diet had begun by at least 275,000 years ago
