Umbilical Artery Half-Peak Systolic Velocity Deceleration Time in Fetal Growth Restriction
(2016)
Objective: To study the umbilical artery (UA) half-peak systolic velocity deceleration time (hPSV-DT) in pregnancies complicated by fetal growth restriction (FGR). Methods: The study included 266 singleton, high-risk ...
Research into the effects of seawater velocity variation on migration imaging in deep-water geology
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-07-01)
This paper aims at the problem that in deep water the migration quality is poor, and starts with the influence that velocity model accuracy has on migration, studying influence that variable seawater velocity makes on ...
True amplitude migration in constant gradient velocity media
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2003)
El algoritmo de Kirchhoff con trazado de rayo se basa en una función de velocidad constante. Esta solución incorpora información de trayectoria de rayos dentro del algoritmo, el cual puede extenderse a un medio de velocidad ...

The velocity field in MOND cosmology
(2016)
The recently developed code for N-body/hydrodynamics simulations in Modified Newtonian Dynamics (MOND), known as raymond, is used to investigate the consequences of MOND on structure formation in a cosmological context, ...
Measurement of the velocity eld in parametrically excited solitary waves
(Cambridge University Press, 2014)
Parametrically excited solitary waves emerge as localized structures in high-aspectratio
free surfaces subject to vertical vibrations. Herein, we provide the first experimental
characterization of the hydrodynamics of ...
Rotational velocities of the giants in symbiotic stars - I. D '-type symbiotics
(BLACKWELL, 2006-02-01)
We have measured the rotational velocities (v sin i) of the mass donors in a number of D'-type symbiotic stars (SSs), using the cross-correlation function method. Four out of five D' SSs with known v sin i appeared to be ...
Silicon monoxide and methanol emission from the NGC 2071 molecular outflow
(2000-12-20)
We report observations of emission in the J\3]2 and J\2]1 transitions of SiO and Jk\
3k transitions of made with the Swedish-ESO Submillimeter Telescope (SEST), toward the
]2k CH3OH,
high-velocity, collimated molecular ...
Head position and cerebral blood flow velocity in acute ischemic stroke: A systematic review and meta-analysis
(S. Karger AG, 2014)
Background: Patients with acute ischemic stroke (AIS) have impaired vasomotor reactivity, especially in the affected cerebral hemisphere, such that they may depend directly on systemic blood pressure to maintain perfusion ...
