Isolation of High Oxygen Affinity Hfmoclobins

Hemoglobin, 1977
This paper describes a method for isolating high oxygen affinity hemoglobins. It involves the selective derivatisation of the cysteine residue at position 93 in the beta chain. The iodoacetamide derivative of the high oxygen affinity hemoglobin was separated from the more negatively charged iodoacetic acid derivative of HbA on DEAE-Sephadex. The method

High performance rotational vibration isolator

Review of Scientific Instruments, 2013
We present a new rotational vibration isolator with an extremely low resonant frequency of 0.055 ± 0.002 Hz. The isolator consists of two concentric spheres separated by a layer of water and joined by very soft silicone springs. The isolator reduces rotation noise at all frequencies above its resonance which is very important for airborne mineral ...

High-isolation optical isolator using a BiCaInVIG single crystal

Applied Optics, 1992
To the best of our knowledge this is the first time a new optical isolator has been developed that uses BiCaInVIG, a non-rare-earth iron garnet. The device has high isolation > 40 dB with an insertion loss of 1.0 dB at 1.3-microm wavelength and > 43 dB with 1.1 dB at 1.52-microm wavelength, including Fresnel reflection losses of ~0.8 dB for two ...

Device isolation in high-density LOCOS-isolated CMOS

IEEE Transactions on Electron Devices, 1987
Leakage paths between n- and p-channel devices in high packing density CMOS circuits fabricated using standard LOCOS isolation are investigated. Experimental results and the results of two-dimensional numerical modeling are presented for both a conventional n-well and a retrograde n-well technology.

High-frequency vibration isolation

Journal of Sound and Vibration, 1966
Abstract Concepts applicable to high-frequency vibration isolation are reviewed with the primary intent of providing insight into the important phenomena. Generalized expressions for transmissibility and isolation effectiveness are presented, which are applicable to isolation of one point of a linear system and which take into account isolator mass ...
