Possible Remedies for Monopolistic Conditions in the Lumber Industry

In a previous issue of the Forester the writer traced the early history of the United States forestry policy. In a monograph which is now in the publisher\u27s hands the history of that forest policy has been brought down to the present time, and the results have been analyzed in detail. In that monograph the writer has indicated how as a result of the unwise policy pursued by Congress most of the timberlands of the country have gravitated into the hands of a few holders, and how, upon the basis of this concentration in the ownership of the standing timber, there have developed certain monopolistic conditions in the lumber manufacturing industry. It is the purpose of the present article to consider the various ways of dealing with this so-called lumber trust

A Chapter in the Early History of the United States Forest Policy

The attitude of the early settlers toward the timber resources of the country was generally one of carelessness or even hostility. This was only natural and inevitable, since in most regions the land was covered with forests, which must be cleared off before agriculture was possible, which represented only an obstacle to the spread of civilization-a negative value. Toward a resource which at first seemed inexhaustible and only a bar to progress, there could at least be no attitude of conservation

Why pedal power and why now? Exploring the possible economic and health benefits of large scale promotion and adoption of cycling as one of the primary means of transport in Malta

This paper will examine the possible economic and health benefits of large scale promotion and adoption of cycling as one of the primary means of transport in Malta. The paper will also propose a model of cost neutral transition as well as examine the particular areas of health expenditure that could be reduced.Bajada New Energy Ltd., CD Power Saving Co.

Coronagraph focal-plane phase masks based on photonic crystal technology: recent progress and observational strategy

Photonic crystal, an artificial periodic nanostructure of refractive indices, is one of the attractive technologies for coronagraph focal-plane masks aiming at direct imaging and characterization of terrestrial extrasolar planets. We manufactured the eight-octant phase mask (8OPM) and the vector vortex coronagraph (VVC) mask very precisely using the photonic crystal technology. Fully achromatic phase-mask coronagraphs can be realized by applying appropriate polarization filters to the masks. We carried out laboratory experiments of the polarization-filtered 8OPM coronagraph using the High-Contrast Imaging Testbed (HCIT), a state-of-the-art coronagraph simulator at the Jet Propulsion Laboratory (JPL). We report the experimental results of 10-8-level contrast across several wavelengths over 10% bandwidth around 800nm. In addition, we present future prospects and observational strategy for the photonic-crystal mask coronagraphs combined with differential imaging techniques to reach higher contrast. We proposed to apply the polarization-differential imaging (PDI) technique to the VVC, in which we built a two-channel coronagraph using polarizing beam splitters to avoid a loss of intensity due to the polarization filters. We also proposed to apply the angular-differential imaging (ADI) technique to the 8OPM coronagraph. The 8OPM/ADI mode mitigates an intensity loss due to a phase transition of the mask and provides a full field of view around central stars. We present results of preliminary laboratory demonstrations of the PDI and ADI observational modes with the phase-mask coronagraphs
