Cable compounds are materials used to prevent the ingress of moisture into telecommunication and power transmission cables. The compound used varies depending upon the type of cable; generally, they are either soft waxy compounds (for use in copper-wire telecom cables), soft thixotropic gels with a consistency similar to that of hair gel (for use in optical fibre cables), or resin/polymer ...
Pergolide, sold under the brand name Permax and Prascend (veterinary) among others, is an ergoline-based dopamine receptor agonist used in some countries for the treatment of Parkinson's disease. Parkinson's disease is associated with reduced dopamine synthesis in the substantia nigra of the brain. Pergolide acts on many of the same receptors ...
Voltage drop exists in both the supply and return wires of a circuit. If the voltage drop across each resistor is measured, the measurement will be a significant number. That represents the energy used by the resistor. The larger the resistor, the more energy used by that resistor, and the bigger the voltage drop across that resistor.
The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
Its disadvantages include the cost of refrigeration of the wires to superconducting temperatures (often requiring cryogens such as liquid nitrogen or liquid helium), the danger of the wire quenching (a sudden loss of superconductivity), the inferior mechanical properties of some superconductors, and the cost of wire materials and construction.

The college football transfer portal is again reshaping rosters, notably at the quarterback position. Our rankings of the signal callers on the move.
The wire is not round but has grooves at the sides to allow the hangers to attach to it. Sizes were (in cross-sectional area) 85, 100, or 150 mm 2. To make the wire stronger, 0.04% tin might be added. The wire must resist the heat generated by arcing and thus such wires should never be spliced by thermal means.
Vitamin D and calcium are essential for overall health, but don’t reduce the risk of falls or fractures in generally healthy older adults, according to a new draft recommendation from the US ...
