Anomalous flow behaviour of bauxite tailings
(1994-10-01)
This paper deals with the anomalous flow behaviour observed in two bauxite tailings pumping systems, with 450 mm and 680 mm outer diameter. In order to enlarge the pipeline lengths in the field, tests were carried out in ...
Tumor Necrosis Factor alpha and Interleukin-1 beta Modulate Calcium and Nitric Oxide Signaling in Mechanically Stimulated Osteocytes
(Wiley-liss, 2009-11-01)
Objective. Inflammatory diseases often coincide with reduced bone mass. Mechanoresponsive osteocytes regulate bone mass by maintaining the balance between bone formation and resorption. Despite its biologic significance, ...
Foetal echoencephalography and Doppler ultrasonography of the middle cerebral artery in canine foetuses
(2013-03-01)
Objectives: This study aimed to evaluate the characteristics of the brain and vascular indicesof the middle cerebral artery of canine foetuses. Methods: Twenty-five bitches were selected. Tissue development, echogenicity, ...
Ophthalmic artery Doppler velocimetry in healthy pregnancy
(Elsevier B.V., 2008-03-01)
Objectives: To establish normative data for ophthalmic artery Doppler parameters throughout a healthy pregnancy, to investigate the possible correlation between these Doppler measurements and gestational age, and to test ...
Central control of cardiorespiratory interactions in fish
(Elsevier Gmbh, Urban & Fischer Verlag, 2009-01-01)
Fish control the relative flow rates of water and blood over the gills in order to optimise respiratory gas exchange. As both flows are markedly pulsatile, close beat-to-beat relationships can be predicted. Cardiorespiratory ...
Transient fetal blood redistribution associated with maternal supine position
(Walter De Gruyter Gmbh, 2017)
Objective: To investigate whether fetal blood circulation is influenced by the maternal supine position. Methods: The inclusion criteria were good health, a singleton pregnancy, maternal age between 18 and 40 years, ...
Effect of total abdominal hysterectomy on ovarian blood supply in women of reproductive age
(Amer Inst Ultrasound Medicine, 2005-02-01)
Objective. The purpose of this study was to evaluate the effect of total abdominal hysterectomy on ovarian blood supply using transvaginal color Doppler ultrasonography in women of reproductive age. Methods. This prospective ...
Ophthalmic artery Doppler as a measure of severe pre-eclampsia
(Elsevier B.V., 2008-03-01)
Objective: To identify differences in orbital flow behavior in mild and severe pre-eclamptic women compared with healthy pregnant women, demonstrated by ophthalmic artery Doppler indexes. Methods: Ophthalmic artery Doppler ...
