74 MHz Discrete HII Absorption Regions Towards The Inner Galaxy (2006)

Nord, Michael E., Henning, P. A., Rand, R. J., Lazio, T. Joseph W., Kassim, Namir E.

At low radio frequencies (< 100 MHz), classical HII regions may become optically thick (optical depth > 1) and can be observed as discrete absorption regions against the Galactic nonthermal...

The Lifetime of Grand Design (2005)

Merrifield, M. R., Rand, R. J., Meidt, S. E.

The lifetime of the structure in grand design spiral galaxies is observationally ill-determined, but is essentially set by how accurately the pattern's rotation can be characterized by a single...

Pattern Speeds of Spiral Galaxies Using the Tremaine-Weinberg Method (2005)

Meidt, S. E., Rand, R. J.

Spiral galaxies displaying molecule-dominated ISMs are potential candidates for pattern speed determination by the Tremaine-Weinberg (TW) method (1984); the molecular gas of such galaxies, as traced...

Imaging Fabry-Perot Spectroscopy of NGC 5775: Kinematics of the Diffuse Ionized Gas Halo (2005)

Heald, G. H., Rand, R. J., Benjamin, R. A., Collins, J. A., Bland-Hawthorn, J.

We present imaging Fabry-Perot observations of Halpha emission in the nearly edge-on spiral galaxy NGC 5775. We have derived a rotation curve and a radial density profile along the major axis by...

SparsePak Observations of Diffuse Ionized Gas Halo Kinematics in NGC 891 (2005)

Heald, G. H., Rand, R. J., Benjamin, R. A., Bershady, M. A.

We present WIYN SparsePak observations of the diffuse ionized gas (DIG) halo of NGC 891. Preliminary results of an analysis of the halo velocity field reveal a clear gradient of the azimuthal...

Kinematics of Diffuse Ionized Gas Halos (2004)

Rand, R. J.

Existing long-slit spectral data for edge-on spiral galaxies suggesting that their Diffuse Ionized Gas (DIG) halos rotate slower than their underlying disks are summarized. An attempt to characterize...

Kinematics of the Ionized Halo of NGC 5775 (2004)

Heald, G. H., Rand, R. J., Benjamin, R. A., Collins, J. A., Bland-Hawthorn, J.

Studies of the kinematics of gaseous halos in some spiral galaxies have shown that the rotational velocity of the gas decreases with height above the midplane (z). This vertical velocity gradient has...

The Pattern Speeds of M51, M83 and NGC 6946 Using CO and the Tremaine-Weinberg Method (2004)

Zimmer, P., Rand, R. J., McGraw, J. T.

In spiral galaxies where the molecular phase dominates the ISM, the molecular gas as traced by CO emission will approximately obey the continuity equation on orbital timescales. The Tremaine-Weinberg...

Kinematics of Diffuse Ionized Gas Halos: A Ballistic Model of Halo Rotation (2002)

Collins, J. A., Benjamin, R. A., Rand, R. J.

To better understand diffuse ionized gas kinematics and halo rotation in spiral galaxies, we have developed a model in which clouds are ejected from the disk and follow ballistic trajectories through...

Kinematics of ionized and molecular hydrogen in the core of M100 (1999)

Knapen, J. H., Shlosman, I., Heller, C. H., Rand, R. J., Beckman, J. E., Rozas, M.

We present high angular and velocity resolution two-dimensional kinematic observations in the spectral lines of H alpha and CO J=1-0 of the circumnuclear starburst region in the barred spiral galaxy...

The Eastern Arm of M83 Revisited: High-Resolution Mapping of 12CO 1-0 Emission (1998)

Rand, R. J., Lord, S. D., Higdon, J. L.

We have used the Owens Valley Millimeter Array to map 12CO (J=1-0) along a 3.5 kpc segment of M83's eastern spiral arm at resolutions of 6.5"x3.5", 10", and 16". The CO emission in most of this...

The Detection of Massive Molecular Complexes in the Ring Galaxy System Arp 143 (1997)

Higdon, J. L., Rand, R. J., Lord, S. D.

We have imaged the kpc scale distribution of 12CO(J=1-0) emission in the ring galaxy Arp 143 (NGC 2444/5) using the OVRO millimeter array. We find two giant molecular complexes in the ring component...

General practitioner obstetrics in Bradford.

Bryce, F C, Clayton, J K, Rand, R J, Beck, I, Farquharson, D I, Jones, S E

The standard of obstetrics care by general practitioners in Bradford was assessed by reviewing the case records of all women who in 1988 were booked for delivery under their general practitioner but...

Bryce, F C, Clayton, J K, Rand, R J, Beck, I, Farquharson, D I, Jones, S E

The standard of obstetrics care by general practitioners in Bradford was assessed by reviewing the case records of all women who in 1988 were booked for delivery under their general practitioner but...

T- and B-lymphocyte subpopulations following radiotherapy for invasive squamous cell carcinoma of the uterine cervix.

Rand, R J, Jenkins, D M, Bulmer, R

Lymphocyte subpopulations in patients with cervical carcinoma were studied before and after radiotherapy. T lymphocytes were recognized by their ability to form spontaneous rosettes with sheep...

T- and B-lymphocyte subpopulations in pre-invasive and invasive carcinoma of the cervix.

Rand, R J, Jenkins, D M, Bulmer, R

Lymphocyte subpopulations in patients with pre-invasive and invasive cervical carcinoma, other gynaecological malignancies and controls were studied. T lymphocytes were recognized by their ability to...

Cryotherapy in the management of cervical ectopy.

Mohanty, K C, Rand, R J, Berry, B

Sixty-five patients with benign ectopy of the uterine cervix were treated by cryosurgery in the departments of genitourinary medicine at St Luke's Hospital, Bradford, and the Airedale General...
