The same 5-foot white PVC pipe was used as a measuring rod in all three pictures. In this this montage, all three trees are in their second growing season and a part of a Texas Cooperative Extension forestry research project.
Forest landowners can greatly increase the survival rate of pine tree seedlings by changing when and how they plant, according to research conducted here. "There’s been too many (reforestation) failures over the last decade or so," said Dr. Eric Taylor, Texas Cooperative Extension forestry specialist. "Some landowners have had to replant two, three or even four years in a row because of poor seedling survival."
Second-year data from an ongoing comparison of planting methods show that survival rates could be significantly increased by using containerized seedlings and planting in the fall instead of the winter or early spring.
In 2000, a Texas Forest Service survey showed Texas had 12 million acres in forest land, all of it in the East Texas Piney Woods area. Approximately 61 percent of the forest land was owned by non-industrial private forest landowners. Another 32 percent was owned by industry and investment groups, and the remainder was publicly owned. In 2000, approximately 160,000 acres were being replanted each year. Non-industrial private landowners accounted for about half of the replantings.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
