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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
