  2. Diversity Immigrant Visa - Wikipedia

    en.wikipedia.org/wiki/Diversity_Immigrant_Visa

    Starting in 2019, for DV-2021, applicants had to hold a valid passport and provide its number on the lottery entry form. This requirement reduced the number of applicants by more than half compared to previous years.

  3. Ejection fraction - Wikipedia

    en.wikipedia.org/wiki/Ejection_fraction

    Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...

  4. Common carotid artery - Wikipedia

    en.wikipedia.org/wiki/Common_carotid_artery

    Typically, blood flow velocities in the common carotid artery are measured as peak systolic velocity (PSV) and end diastolic velocity (EDV). In a study of normative men aged 20-29 years, the average PSV was 115 cm/sec and EDV was 32 cm/sec. In men 80 years and older, the average PSV was 88 cm/sec and EDV was 17 cm/sec. [7]

    National Security Clearances are a hierarchy of levels, depending on the classification of materials that can be accessed—Baseline Personnel Security Standard (BPSS), Counter-Terrorist Check (CTC), Enhanced Baseline Standard (EBS), Security Check (SC), enhanced Security Check (eSC), Developed Vetting (DV), enhanced Developed Vetting (eDV), and STRAP.

  6. External ventricular drain - Wikipedia

    en.wikipedia.org/wiki/External_ventricular_drain

    The EVD is leveled to a common reference point that corresponds to the skull base, usually the tragus or external auditory meatus.The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist.

  7. End-diastolic volume - Wikipedia

    en.wikipedia.org/wiki/End-diastolic_volume

    Because greater EDVs cause greater distention of the ventricle, EDV is often used synonymously with preload, which refers to the length of the sarcomeres in cardiac muscle prior to contraction . An increase in EDV increases the preload on the heart and, through the Frank-Starling mechanism of the heart, increases the amount of blood ejected ...

  8. Vertebral artery - Wikipedia

    en.wikipedia.org/wiki/Vertebral_artery

    Normally, vertebral artery blood flow velocity can be 63.6 ± 17.5 cm/s during PSV and 16.1 ± 5.1 cm/s during EDV according to a study done by Kuhl et al. [16] Due to vertebral artery dominance, measurements can vary on both sides, for example, another study by Seidel et al. found that the right side had an average of 45.9 cm/s and the left ...

    The Rivian EDV (Electric Delivery Van) and ECV (Electric Commercial Van), also known as the Delivery, are a line of battery-electric cargo vehicles built by Rivian.Initially they were exclusive to its investor Amazon, which uses the EDV for package delivery, but in November 2023, sales were opened to other companies as the ECV / Delivery, with minor cosmetic changes.
