A recently completed economic study of timber demand projections for the next two decades in southeast Alaska explains four alternatives describing how the forest products industry could develop. The peer-reviewed study now in process of being published, Timber Products Output and Timber Harvests in Alaska: Projections for 2005-25, was prepared by Pacific Northwest Research Station scientists Allen Brackley, Thomas Rojas, and Richard Haynes.
"The projections of future demand are represented in our study by four scenarios," explains Brackley, a research forester based at the Alaska Wood Utilization Research and Development Center in Sitka, Alaska. "The first scenario projects a future very similar to the recent past. The second one assumes that lumber production increases and is stimulated by marketing and promotion programs that recognize the unique characteristics of lumber produced from the region. Scenarios three and four assume that an integrated industry returns to southeast Alaska.
"In 2015, the projected derived demand (a 5-year average based from 2013 to 2017) for forest products from southeast Alaska ranges from 37.9 to 299.0 million board feet (Scribner C-log scale), and the maximum projected derived demand in 2025 is 360 million board feet. An implicit assumption of all the scenarios is that an economically viable timber supply is available in southeast Alaska."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
