Granite State Poll for New Hampshire Estuaries Project

The University of New Hampshire Survey Center included a question on its July 2004 Granite State Poll for the New Hampshire Estuaries Project. The major purposes of these questions were to assess the knowledge of New Hampshire residents concerning the meaning of an estuary. Five hundred and nine (509) New Hampshire adults were interviewed by telephone between July 6 and July 20, 2004

Two-dimensional Moist Stratified Turbulence and the Emergence of Vertically Sheared Horizontal Flows

Moist stratified turbulence is studied in a two-dimensional Boussinesq system influenced by condensation and evaporation. The problem is set in a periodic domain and employs simple evaporation and condensation schemes, wherein both the processes push parcels towards saturation. Numerical simulations demonstrate the emergence of a moist turbulent state consisting of ordered structures with a clear power-law type spectral scaling from initially spatially uncorrelated conditions. An asymptotic analysis in the limit of rapid condensation and strong stratification shows that, for initial conditions with enough water substance to saturate the domain, the equations support a straightforward state of moist balance characterized by a hydrostatic, saturated, vertically sheared horizontal flow (VSHF). For such initial conditions, by means of long time numerical simulations, the emergence of moist balance is verified. Specifically, starting from uncorrelated data, subsequent to the development of a moist turbulent state, the system experiences a rather abrupt transition to a regime which is close to saturation and dominated by a strong VSHF. On the other hand, initial conditions which do not have enough water substance to saturate the domain, do not attain moist balance. Rather, the system remains in a turbulent state and oscillates about moist balance. Even though balance is not achieved with these general initial conditions, the time scale of oscillation about moist balance is much larger than the imposed time scale of condensation and evaporation, thus indicating a distinct dominant slow component in the moist stratified two-dimensional turbulent system.Comment: 23 pages. 9 figure

Many new voters make the Granite State one to watch in November

A third of potential voters in New Hampshire during the fall of 2008 have become eligible to vote in the state. Further, these potential new voters are more likely to identify with the Democratic Party and less likely to identify as Republicans than are established New Hampshire voters, contributing to the state\u27s purple status

The structure and function of adhesive gels from invertebrates

SYNOPSIS. Many marine invertebrates form strong, temporary attachments using viscoelastic gels. To better understand these adhesives, an analysis of what is known of gel structure and function was performed. There are different ways of making gels, ranging from entangling of giant glycoproteins to crosslinking of smaller proteins. The mechanics of the gel depend largely on the size of the polymer, its concentration, and whether it is crosslinked. Compared to gels such as mammalian mucus, the mechanics of adhesive mucous gels often appear to depend more heavily on relatively small proteins than on megadalton-sized glycoproteins. In addition, changes in concentration and the presence of specific proteins have been associated with the change from a non-adhesive to an adhesive form. The attachment strengths produced by different gels at different concentrations were compared with the changes in attachment strength seen in living animals. These data suggest that changes in concentration are not sufficient to account for adhesion. Thus, it is likely that the changes in protein composition may play a large role

Fault Diagnosis of Reciprocating Compressors Using Revelance Vector Machines with A Genetic Algorithm Based on Vibration Data

This paper focuses on the development of an advanced fault classifier for monitoring reciprocating compressors (RC) based on vibration signals. Many feature parameters can be used for fault diagnosis, here the classifier is developed based on a relevance vector machine (RVM) which is optimized with genetic algorithms (GA) so determining a more effective subset of the parameters. Both a one-against-one scheme based RVM and a multiclass multi-kernel relevance vector machine (mRVM) have been evaluated to identify a more effective method for implementing the multiclass fault classification for the compressor. The accuracy of both techniques is discussed correspondingly to determine an optimal fault classifier which can correlate with the physical mechanisms underlying the features. The results show that the models perform well, the classification accuracy rate being up to 97% for both algorithms

The Relative Contribution of Calcium, Zinc and Oxidation-Based Cross-Links to the Stiffness of Arion Subfuscus Glue

Metal ions are present in many different biological materials, and are capable of forming strong cross-links in aqueous environments. The relative contribution of different metal-based cross-links was measured in the defensive glue produced by the terrestrial slug Arion subfuscus. This glue contains calcium, magnesium, zinc, manganese, iron and copper. These metals areessential to the integrity of the glue and to gel stiffening. Removal of all metals caused at least a 15-fold decrease in the storage modulus of the glue. Selectively disrupting cross-linksinvolving hard Lewis acids such as calcium reduced the stiffness of the glue, while disrupting cross-links involving borderline Lewis acids such as zinc did not. Calcium is the most common cation bound to the glue (40 mmol/l), and its charge is balanced primarily by sulphate at 82-84 mmol/l. Thus these ions probably play a primary role in bringing polymers together directly. Imine bonds formed as a result of protein oxidation also contribute substantially to the stiffness of the glue. Disrupting these bonds with hydroxylamine caused a 33% decrease in storage modulus of the glue, while stabilizing them by reduction with sodium borohydride increased thestorage modulus by 40%. Thus a combination of metal-based bonds operates in this glue. Most likely, cross-links directly involving calcium play a primary role in bringing together andstabilizing the polymer network, followed by imine bond formation and possible iron coordination.
