Impact of geologic heterogeneity on recharge estimation using environmental tracers: Numerical modeling investigation

Autor: S. H. Conrad, J. T. McCord, C. A. Gotway

Publikováno v: Water Resources Research. 33:1229-1240

This paper presents a numerical modeling approach for assessing the impacts of geologic heterogeneity on groundwater recharge estimates derived from environmental tracers. Common to many of the environmental tracer methods used to infer recharge in a

Soil-water flux in the Southern Great Basin, United States: Temporal and spatial variations over the last 120,000 years

Autor: S. H. Conrad, D.P. Hammermeister, J. B. Chapman, D.O. Blout, J. J. Miller, Scott W. Tyler, M.J. Sully, J.M. Ginanni

Publikováno v: Water Resources Research. 32:1481-1499

The disposal of hazardous and radioactive waste in arid regions requires a thorough understanding of the occurrence of soil-water flux and recharge. Soil-water chemistry and isotopic data are presented from three deep vadose zone boreholes (>230 m) a

Fetal toxicity of zidovudine (azidothymidine) in Macaca nemestrina: preliminary observations

Autor: J C, Ha, C, Nosbisch, S H, Conrad, G C, Ruppenthal, G P, Sackett, J, Abkowitz, J D, Unadkat

Publikováno v: Journal of acquired immune deficiency syndromes. 7(2)

The objective of this study was to determine the dam, fetal, and infant toxicity of zidovudine (AZT) administered to pigtailed macaques during pregnancy. Pregnant macaques were administered AZT (1.5 mg/kg/dose every 4 h) or water via gastric catheter

Anencephaly and twins: prenatal ultrasound and estriol

Autor: S J, Waszak, S H, Conrad

Publikováno v: The Journal of reproductive medicine. 22(5)

A rare case of anencephalic twin pregnancy diagnosed prenatally with ultrasonography is reported. It is the only case found in the literature in which maternal 24-hour urinary estriol is documented in an anencephalic twin pregnancy. Ultrasound diagno

Diagnosis of early pregnancy by ultrasound in Macaca fascicularis

Autor: S H, Conrad, G P, Sackett, T M, Burbacher

Publikováno v: Journal of medical primatology. 18(2)

Real-time ultrasonography was used to detect early pregnancy in 32 longtailed macaques (Macaca fascicularis). In 92% of the successful conceptions, a correct diagnosis was made. The earliest sign of pregnancy was an intrauterine ringlike structure (1

Ultrasonic placental localization and bloody taps in midtrimester amniocentesis for prenatal genetic diagnosis

Autor: L E, Karp, R, Rothwell, S H, Conrad, H W, Hoehn, D E, Hickok

Publikováno v: Obstetrics and gynecology. 50(5)

In a prospective study, a small team of obstetricians concurrently performed midtrimester amniocentesis for prenatal genetic diagnosis on 32 patients after ultrasonic placental localization and on 50 patients without prior ultrasound. The use of ultr
