R. C. Wallace (1881-1955)

By the death of Dr. Robert Charles Wallace on 30 January 1955, the Arctic Institute of North America lost more than its Executive Director. The staff and the Governors lost a warm friend. The north lost one who knew it well and who had served it faithfully in a variety of ways during his forty-five years in Canada. So well and so affectionately was he known as "Wallace of Queen's" that his links with the north of Canada were somewhat naturally overshadowed in the minds of many of his friends. To some it seemed strange that, after his distinguished service to Queen's University, and at a time in life when many men would have cast all official duties aside, he willingly accepted the invitation to serve the Arctic Institute in its senior administrative post. But those who knew him well were not surprised nor were they in any doubt that what was supposed to be a "half-time job" was to be for him a labour of love upon which no time limit could be imposed. ..

Permafrost Research

"Problems connected with permafrost, the development of research in Canada and the United States in the last decade, and future research programs are discussed. The problems for research include: an accurate knowledge of permafrost distribution; correlation of permafrost with meteorological statistical studies; the performance of roads, airfields, and buildings in permafrost areas; physical and mechanical properties of frozen ground; and the origin of permafrost."--SIPRE

Pair Wave Functions in Atomic Fermi Condensates

Recent experiments have observed condensation behavior in a strongly interacting system of fermionic atoms. We interpret these observations in terms of a mean-field version of resonance superfluidity theory. We find that the objects condensed are not bosonic molecules composed of bound fermion pairs, but are rather spatially correlated Cooper pairs whose coherence length is comparable to the mean spacing between atoms. We propose experiments that will help to further probe these novel pairs

Intrinsic Josephson effect and nonequilibrium soliton structures in two-gap superconductors

We predict a new dynamic state in current-carrying superconductors with multicomponent order parameter. If the current density J exceeds a critical value J_t, an interband breakdown caused by charge imbalance of nonequilibrium quasiparticles occurs. For J > J_t, the electric field penetrating from current leads gives rise to various static and dynamic soliton phase textures, and voltage oscillations similar to the nonstationary Josephson effect. We propose experiments to observe these effects which would probe the multicomponent nature of the superconducting order parameter.Comment: 4 pages, 4 figure

Heme Oxygnase-1 Produced by a Human Monocytic Cell Line (U-937) After Exposure to Brevetoxin (PbTx-2)

In lieu of an abstract, below is the first paragraph of the paper. Harmful Algal Blooms (HABs) along the west coast of Florida are the result of a large proliferation of the dinoflagellate Karenia brevis. The harmful nature of these algal blooms is the result of potent neurotoxins, specifically referred to as brevetoxins, which are released from K. brevis. PbTx-2 is one of the most abundant brevetoxins during HABs of K brevis and results in extreme mortality of marine wildlife and health implications for humans such as Neurotoxic Shellfish Poisoning (NSP) and immunosuppression. The cellular response to PbTx-2 is not as well known, which was the focus of this research. Oxidative stress, in the form of depleted glutathione and elevated levels of hydrogen peroxide, peroxidase, and/or heme oxygenase-1 (HO-1), is a common defensive response of human cells to a toxin. It was hypothesized that human cells would produce an elevated level of HO-1 in the presence of PbTx- 2 in comparison to cells without PbTx-2. The purpose of this research was to quantify the amount of HO-1 produced by a human monocytic cell line (U-937) when treated with PbTx-2 and use this as an indicator of the level of oxidative stress. Results supported that human cells did undergo oxidative stress in the presence of PbTx-2 and produced an elevated level of HO-1

Pilot Study investigating the Impact of Serial ingestion or Co-ingestion of Creatine and Sodium bicarbonate on Performance Following Completion of a Hypertrophy Type Resistance Exercise Workout.

Purpose: To examine the ergogenic potential of creatine (Cr), sodium bicarbonate (SB),and Cr+SBafter completion of a resistance exercise bout (REB).Methods: Following recruitment,27trained males (26.8±5.7 years old) completed a one repetition maximum strength (1RM) test in the parallel squat (120.9±28.2kg). Participants then followed a standardised meal plan for 4 days whilst ingesting one of 4 supplements, and on day 5 they undertook the REB. This was a double blind randomised placebo-controlled study where participants ingested one of the following: Placebo (PLA, n=7), Cr (20g/d-1& PLA, n=8), SB (0.5 g/kg-1/d-1&PLA, n=6), andCr+SB (5 g/d-1 of Cr & 0.5 g/kg-1/d-1 SB, n=6) divided in 4 doses. The REB consisted of 4x10 repetitions (70% of 1RM, 1½ min recovery). The primary performance outcome was a 5th set (70% of 1RM) performed to volitional exhaustion.Blood glucose and lactate, heart rate, ratings of perceived exertion, sickness and stomachache scales, and time to complete each set were also recorded.Results:Participants in Cr, SB, and Cr+SB completed the required number of repetitions at 70% of 1RM however in PLA they completed the same repetitions at lower intensity (68+3.4%). Participants in PLA, Cr, SB, and Cr+SB completed 8(±1.6), 11(±5.5), 9(±3.7), and 11(±3.3) repetitions respectively during the 5th set. Despite the fact that no significant differences were observed in performance, small (SB: 0.4) and moderate effect (Cr: 0.7; Cr+SB: 1.0) sizes were observed in relation to PLA. Body mass increasedsignificantly after Cr (78.1±8.9 kg pre vs 79.1±8.9 kg post, p<0.05). No other significant differences existed in recorded variables.Conclusions: Performance gains were of higher magnitude in the Cr+SB and Cr groups. Co-ingestion of a small amount of Cr (5 g/d-1) with a standard dose ofSB (0.5 g/kg-1/d-1)appears to be equally beneficial asingestion of a standard dose of Cr (20 g/d-1). The Cr+SB was not associated with significant gains in body mass which may be beneficial in sports where size gains may negate performance. Further research is required, with larger sample size, and specific athletic populations in order to confirm the findings of the current study

Contemporaneous XMM-Newton investigation of a giant X-ray flare and quiescent state from a cool M-class dwarf in the local cavity

We report the serendipitous detection of a giant X-ray flare from the source 2XMM J043527.2-144301 during an XMM-Newton observation of the high latitude molecular cloud MBM20. The source has not been previously studied at any wavelength. The X-ray flux increases by a factor of more than 52 from quiescent state to peak of flare. A 2MASS counterpart has been identified (2MASS J04352724-1443017), and near-infrared colors reveal a spectral type of M8-M8.5 and a distance of (67\pm 13) pc, placing the source in front of MBM20. Spectral analysis and source luminosity are also consistent with this conclusion. The measured distance makes this object the most distant source (by about a factor of 4) at this spectral type detected in X-rays. The X-ray flare was characterized by peak X-ray luminosity of ~8.2E28 erg s-1 and integrated X-ray energy of ~2.3E32 erg. The flare emission has been characterized with a 2-temperature model with temperatures of ~10 and 46 MK (0.82 and 3.97 keV), and is dominated by the higher temperature component.Comment: 19 pages, 5 figures; Accepted for publication on Ap
