Neuronotrophic activities accumulate in vivo within silicone nerve regeneration chambers

Brain Research, 1983
Abstract Rat sciatic nerves can be transected and their proximal and distal stumps sutured into the openings of cylindrical silicone chambers. Anatomical regeneration has been demonstrated across 10 mm long chambers containing both stumps, although little or no axonal outgrowth occurs in chambers omitting the distal stump or exceeding the 10 mm ...

Temporal changes of neuronotrophic activities accumulating in vivo within nerve regeneration chambers

Experimental Neurology, 1983
The presence of neuronotrophic factors (NTFs) in noninjured sciatic nerve extract and the course of their accumulation from 3 h to 30 days after nerve transection was examined. Rat sciatic nerves were transected and their proximal and distal stumps sutured into the openings of cylindrical silicone chambers leaving a 10-mm interstump gap.

A straw chambers’ tracker for the high rate experiment 835 at the Fermilab accumulator

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract Two layers of proportional drift tubes (aluminum mylar straws) are staggered in two cylindrical light chambers to measure charged particles’ azimuthal angle. To stand the high rates (∼10 kHz / cm 2 ) and minimize the pile-up of the high luminosity experiment 835 at FNAL, a fast ASIC Amplifier-Shaper-Discriminator (ASD-8B ...

Portable accumulation chambers for measuring enteric methane in cattle

Breeding has been shown to be a viable solution for reducing methane emissions in ruminants but requires obtaining on-farm measurements of methane. One technology that has successfully been used on-farm to obtain short-term commercial methane measurements in sheep and goats is portable accumulation chambers (PAC).

Assessment of the possibility of DNA accumulation and transfer in a superglue chamber

Journal of Forensic Identification, 2012
Fingerprints may contain DNA, albeit generally at low levels. It is therefore a possibility that DNA may be transferred from a print or other biological material on an exhibit being fingerprinted to an unrelated article during the application of fingerprint techniques where multiple items are processed together or after each other.

Multi-field interactions simulation analysis of new hydraulic accumulator magnetorheological fluid chamber

2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
There is a new type of hydraulic accumulator has been presented in this paper, and for the magnetorheological fluid(MRF) chamber of the new hydraulic accumulator, the modeling and the solving method for the fluid-solid interactions and magnetic- fluid interactions in the MRF chamber are provided and also studied by the finite element method.

Abrupt decline in the rate of accumulation of total protein and yolk in postvitellogenic egg chambers ofDrosophila

Wilhelm Roux's Archives of Developmental Biology, 1983
The accumulation of endogenously synthesized non-yolk proteins, and of exogenously derived yolk, was quantitated during oogenesis and embryogenesis ofDrosophila. Rates of non-yolk protein accumulation were calculated, and were correlated with polysome content at each developmental stage.

[Risk of accumulation of CO₂ in the oxygen chamber in "HOOD" (Experimental study on test bed)].

Annales francaises d'anesthesie et de reanimation, 2012
Oxygen hood is largely used to deliver O₂ to newborn infants with respiratory failure in the northern region of France. The oxygen flow is set to obtain the target arterial blood oxygen saturation. Thus, O₂ flow delivers into the hood may be below the recommended gas flow of 6L/min. However, gas flow below 6L/min exposes to CO₂ rebreathing.

Triggering volcanic eruptions by gas bubbles accumulations in the magma chamber

We present a model for volcanic eruptions in open-conduit condition based on the transport of batches of magma driven by the accumulation of bubbles. The viscosity of the surrounding magma counteracts gravity; however, the primary upward force acting on these bodies is driven by gas vesicles which accumulate beneath the denser bodies.
