A new voltzialean conifer, Emporia royalii sp nov. (Emporiaceae), from the Hamilton Quarry, Kansas.
Download2009
Stockey, R.A., Rothwell, G.W., Hernandez-Castillo, G.R., Mapes, G.
A new species of extinct conifer plants, Emporia royalii sp. nov. Hernandez-Castillo, Stockey, Mapes et Rothwell (Emporiaceae: Voltziales), is described from the rich fossil biota of the Late Pennsylvanian, Hamilton Quarry, Kansas. This conifer has lateral plagiotropic branches with simple and...

A non-ideal osmotic equilibrium equation is proposed as a replacement for the Boyle van’t Hoff equation to describe the equilibrium volume of a living cell as a function of external osmolality. Contrary to common understanding, the Boyle van’t Hoff equation is only valid for ideal, dilute...

This study focuses on simultaneous vibration suppression and energy harvesting in a broad frequency band. For this purpose, a variant nonlinear energy sink (NES) is developed. The developed variant NES consists of a nonlinear oscillator and an electromagnetic energy harvester. Unlike a true NES,...

An individual's competitive ability is often dependent on its size, but the methods commonly used to analyze plant competition experiments generally assume that the outcome of interactions are size independent. A method for the analysis of experiments with paired competition treatments based on...

We construct a continuum model for biological aggregations in which individuals experience long-range social attraction and short range dispersal. For the case of one spatial dimension, we study the steady states analytically and numerically. There exist strongly nonlinear states with compact...

Semantic prosody, or discourse prosody as it is also known, has come to be a familiar dimension of corpus-based lexicology (see Louw 1993, Stubbs 1995, Sinclair 1991, Partington 2004 for examples), though it is not without its critics (cf. Whitsitt 2005). As Whitsitt demonstrates through his...

A novel application of RNase H2-dependent quantitative PCR for detection and quantification of Grosmannia clavigera, a mountain pine beetle fungal symbiont, in environmental samples
Download2018-01-01
McAllister, Chandra H., Fortier, Colleen E., St Onge, Kate R., Sacchi, Bianca M., Nawrot, Meaghan J., Locke, Troy, Cooke, Janice EK
Mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) is an economically and ecologically important pest of pine species in western North America. Mountain pine beetles form complex multipartite relationships with microbial partners, including the ophiostomoid fungi Grosmannia clavigera...

Oxidation of pyrite and other metal sulfides is accelerated by the activity of acidophilic iron- and sulfur-oxidising microorganisms. The ideal biocide for controlling biocatalysed acid rock drainage (ARD) would be inexpensive, inhibitory toward sulfide-oxidising bacteria at low concentrations,...

Mitambo, Mitambo M., Zhang, Shuliang L., Loppnow, Glen R.
A novel four nuclear magnetic resonance (NMR)-tube holder is described for quantitative Raman and resonance Raman spectroscopy. This cell has advantages over other divided cell designs in producing high precision quantitation and eliminating off-axis errors. Raman spectra were obtained for both...

A novel human mutation in the SLC9A1 gene results in abolition of na+/H+ exchanger activity
Download2015-01-01
The SLC9A1 gene, the Na+/H+ exchanger isoform 1 is the principal plasma membrane Na+/H+ exchanger of mammalian cells and functions by exchanging one intracellular proton for one extracellular sodium. The human protein is 815 amino acids in length. Five hundred N-terminal amino acids make up the...
