Assessing the benefit of flow constraints on the drifting invertebrate community of a regulated river

Autor: R. J. Patterson, Karen E. Smokorowski

Publikováno v: River Research and Applications. 27:99-112

The downstream effects of hydroelectric dam operations on the abundance and diversity of the macroinvertebrate drift community of a regulated river were compared to that of an unregulated river, longitudinally and across three seasons. The regulated

Astrometry with TheHubble Space Telescope: A Parallax of the Central Star of the Planetary Nebula NGC 6853

Publikováno v: The Astronomical Journal. 126:2549-2556

We present an absolute parallax and relative proper motion for the central star of the planetary nebula NGC 6853 (The Dumbell). We obtain these with astrometric data from FGS 3, a white-light interferometer on {\it HST}. Spectral classifications and

Interferometric Astrometry with Hubble Space Telescope Fine Guidance Sensor 3:The Parallax of the Cataclysmic Variable TV Columbae

Autor: B. E. McArthur, G. F. Benedict, J. Lee, W. F. van Altena, C. L. Slesnick, J. Rhee, R. J. Patterson, L. W. Fredrick, T. E. Harrison, W. J. Spiesman, E. Nelan, R. L. Duncombe, P. D. Hemenway, W. H. Jefferys, P. J. Shelus, O. G. Franz, L. H. Wasserman

TV Columbae (TV Col) is a 13th magnitude Intermediate Polar (IP) Cataclysmic Variable (CV), with multiple periods found in the light curves. Past estimates predicted a distance of 400 parsec to greater than 500 parsec. Recently completed Hubble Space

Chest radiographs in the evaluation of the febrile infant

Autor: R J Patterson, G S Bisset rd, Donald R. Kirks, A Vanness

Publikováno v: American Journal of Roentgenology. 155:833-835

Chest radiographs are often considered an essential part of the workup of the febrile infant. Anteroposterior and lateral radiographs of the chest are frequently obtained in this group of patients, irrespective of respiratory tract symptoms and/or si

Atretic parietal cephaloceles revisited: an enlarging clinical and imaging spectrum?

Autor: R J, Patterson, J C, Egelhoff, K R, Crone, W S, Ball

Publikováno v: AJNR Am J Neuroradiol

PURPOSE: We describe imaging features that are clues to the diagnosis of atretic cephaloceles and discuss clinical findings and a possible mechanism by which these lesions develop. METHODS: Eight children (five girls and three boys) ranging in age fr

Hypertensive encephalopathy in children

Autor: B V, Jones, J C, Egelhoff, R J, Patterson

Publikováno v: AJNR Am J Neuroradiol

We present five cases of hypertensive encephalopathy in children, three with MR imaging findings and two with CT findings alone. One of the five patients had MR perfusion imaging, which showed perfusion abnormalities that support the concept of vasod

Publikováno v: The Journal of the Arkansas Medical Society. 91(3)

A random retrospective review of the Teen Obstetrical Parenting Perinatal Services (TOPPS) clinic medical records for 1985 to 1989 was completed on 120 adolescent mothers (30 charts for each year). The purpose of this study was to evaluate maternal a
