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...

Comparison of the open‐closed separatrix in a global magnetospheric simulation with observations: The role of the ring current
Download2010
Kabin, Konstantin, Lu, J. Y., Rankin, Robert, Gombosi, Tamas I., Watt, Clare E. J., Ridley, Aaron J., Toth, Gabor, Milan, Steve E., Zhang, Jichun, Rae, I. Johnathan, Clauer, C. Robert, De Zeeuw, Darren L., Fenrich, Frances
The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...

Elkington, Scot R., Degeling, Alex W., Rankin, Robert
The process of magnetospheric radiation belt electron transport driven by ULF waves is studied using a 2-D ideal MHD model for ULF waves in the equatorial plane including day/night asymmetry and a magnetopause boundary, and a test kinetic model for equatorially mirroring electrons. We find that...

Tikhonchuk, V. T., Voronkov, I., Frycz, P., Samson, J. C., Rankin, Robert
The nonlinear dynamics of a shear flow and its subsequent evolution in the equatorial plane of the inner plasma sheet is studied. A linear analysis of the ideal MHD equations reveals a hybrid vortex instability which appears because of the coupling of Kelvin-Helmholtz (KH) and Rayleigh-Taylor...

Kabin, Konstantin, Rankin, Robert, Ozeke, Louis G., Degeling, Alex W., Mann, Ian R.
The adiabatic drift-resonant interaction between relativistic, equatorially mirroring electrons and narrowband, Pc 5 ultra low frequency (ULF) waves in the magnetosphere is investigated using a time-dependent magnetohydrodynamic (MHD) wave model. Attention is focused on the effect of a ULF wave...

Effect of age of the intermediate host Tribolium confusum (Coleoptera) on infection by Hymenolepis diminuta (Cestoda).
Download2008
A cross-sectional study of 27 cohorts of Tribolium confusum aged 2–78 wk was done to examine effects of host age on exposure to eggs of Hymenolepis diminuta under standardized conditions. Pre-exposure, fasting, and postexposure mortality were low, sex ratio was equal, and fecundity of hosts was...

Rankin, Robert, Trichtchenko, Larisa, Yuan, Xingqiu, Cairns, Iver H.
Recent simulation results have revealed that energetic electron bursts are produced cyclically at the shock reformation period upstream of reforming shocks and are qualitatively very different from the continuous beam expected from time-stationary shocks (Yuan et al., 2007a). This paper extends...

Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Le, G. M., Wang, J. S., Lei, J., Rae, I. Johnathan
A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

Estimation of spatiotemporal transmission dynamics and analysis of management scenarios for sea lice of farmed and wild salmon
Download2020-01-01
Stephanie J. Peacock, Martin Krkošek, Andrew W. Bateman, Mark A. Lewis
Parasite transmission between farmed and wild salmon affects the sustainability of salmon aquaculture in Pacific Canada. Understanding and managing parasites in aquaculture is challenged by spatial and temporal variation in transmission dynamics. We developed a mechanistic model that connects sea...

Fecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
Download2004
Karels, T. J., Koppel, L., Hik, D. S.
We evaluated fecal pellet counts as an index of hoary marmot (Marmota caligata) social group size in order to develop a simple, inexpensive method for monitoring population change of a widely distributed, but poorly studied alpine mammal. Fecal pellet counts were conducted in three separate...
