Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Ram-pressure confinement of extragalactic jets [PDF]

Monthly Notices of the Royal Astronomical Society, 1994
The confinement problem of extragalactic jets is considered. It is shown that a significant increase of the kinetic luminosity of the central source can lead to much higher pressure in the jets as compared to the thermal pressure of the external gas. The sideways expansion of such overpressured jets is effectively restrained by the high inertia of the ...
