Ericsson AXE cabinets. The AXE telephone exchange is a product line of circuit switched digital telephone exchanges manufactured by Ericsson, a Swedish telecom company.It was developed in 1974 by Ellemtel, a research and development subsidiary of Ericsson and Televerket. [1]
ARF binds to two forms of the guanosine nucleotide, guanosine triphosphate (GTP) and guanosine diphosphate (GDP). The shape of the ARF molecule is dependent upon the form to which it is bound, allowing it to serve in a regulatory capacity. ARF requires assistance from other proteins in order to switch between binding to GTP and GDP.
Rotary airlock; The basic use of the rotary airlock feeder is as an airlock transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure and suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to ...
A feeder line is a peripheral route or branch in a network, which connects smaller or more remote nodes with a route or branch carrying heavier traffic. The term is applicable to any system based on a hierarchical network. In telecommunications, a feeder line branches from a main line or trunk line.
The network protector is installed to protect the stability and reliability of the secondary grid by preventing power flow away from the customers and into the primary feeders. If there is a fault on the primary feeder, the substation circuit-breaker is meant to open, disconnecting the primary feeder from one side. The problem is that this ...
ADP-ribosylation factor 1 (ARF1) is a member of the human ARF gene family. The family members encode small guanine nucleotide-binding proteins that stimulate the ADP-ribosyltransferase activity of cholera toxin and play a role in vesicular trafficking as activators of phospholipase D. The gene products, including 6 ARF proteins and 11 ARF-like ...
The ARF format is designed to be extensible, providing for generic spam reporting, e.g. from users to some anti-spam center or help desk, or for opt-out operations. The format defines a new MIME type to be included in a multipart/report attachment, and includes at least the headers of the offending message.
An ADF indicator with a fixed azimuth dial. The airplane is flying a 40° magnetic heading, while the station is 310° relative to the plane (called "relative bearing").
