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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
