Lamprey watershed education and outreach

The Lamprey River Nomination Committee sought the assistance of the Piscataqua Region Estuaries Partnership (PREP) to complete an extensive and detailed information package to nominate the Lamprey River and its major tributaries to the NH Rivers Management and Protection Program. The nomination package was due at DES on June 1, 2010, was reviewed and accepted by the State Rivers Management Committee in September and forwarded to the Commissioner of DES. The nomination is now working through the NH legislature with hearings anticipated during the spring 2011 session. If passed, the bill should be signed by Governor Lynch in July of 2011. Assistance from PREP was essential for the completion of a major outreach effort to landowners along the rivers under consideration, communication with each town selec tboard, planning board and conservation commission, and with many partners and organizations throughout the watershe

PEER Arizona strong-motion database and GMPEs evaluation

This report summarizes the products and results of a study on the collection, processing, and analysis of earthquake ground-motions recorded in Arizona at several recording stations within 200 km from the Palo Verde Nuclear Generating Station in central Arizona. The recorded ground motion in Arizona were compiled and processed according to the Pacific Earthquake Engineering Research Center’s (PEER) record-processing standards. Shear wave velocity profiles at ten recording stations were measured through the spectral analysis of surface wave dispersion technique. Additionally, “kappa” a measure of energy dissipation in the top 1 to 2 km of the crust, was estimated by three methodologies. The average κ0 (kappa at zero-kilometer distance) was estimated from all sites as 0.033 sec. Finally, response spectra of the recorded ground motions in Arizona were compared with those predicted by the NGA-West2 ground motion prediction equations at large distances in Arizona. The comparison showed that overall the recorded 5% damped response spectral ordinates were over predicted by the NGA-West2 models by a range of 0-0.35 natural log units for events occurring in Central California, and by a range of 0.2-0.7 natural log units for events occurring in Southern California and the Gulf of California

On the Complexity of Recognizing S-composite and S-prime Graphs

S-prime graphs are graphs that cannot be represented as nontrivial subgraphs of nontrivial Cartesian products of graphs, i.e., whenever it is a subgraph of a nontrivial Cartesian product graph it is a subgraph of one the factors. A graph is S-composite if it is not S-prime. Although linear time recognition algorithms for determining whether a graph is prime or not with respect to the Cartesian product are known, it remained unknown if a similar result holds also for the recognition of S-prime and S-composite graphs. In this contribution the computational complexity of recognizing S-composite and S-prime graphs is considered. Klav{\v{z}}ar \emph{et al.} [\emph{Discr.\ Math.} \textbf{244}: 223-230 (2002)] proved that a graph is S-composite if and only if it admits a nontrivial path-$k$-coloring. The problem of determining whether there exists a path-$k$-coloring for a given graph is shown to be NP-complete even for $k=2$. This in turn is utilized to show that determining whether a graph is S-composite is NP-complete and thus, determining whether a graph is S-prime is CoNP-complete. Many other problems are shown to be NP-hard, using the latter results

The Originality of Fredrick Jackson Turner as an Historian and Teacher

The originality of Frederick Jackson Turner can be recognized against a background consisting of evidence of his contributions to the two fields, history and teaching. The stage will be set by a short biographical treatment of Turner. This avenue of approach will lead to an elaboration of Turner\u27s major historical interpretation. This concept will be described and two subordinate facets of his thesis will be examined briefly. The teaching aspects of Turner\u27s career will be illuminated by analyzing the inseparable historian-teacher relationship and, in addition, the quality and lasting effects of his influence will be treated. It is not the design here to attempt to criticize or present a summary of either Turner\u27s Work or that of his supporters or critics
