Some truss rod systems, called " double action " truss systems, tighten both ways, allowing the neck to be pushed both forward and backward ( standard truss rods can only be released to a point beyond which the neck is no longer compressed and pulled backward ).

In British oval racing, the term Production car racing has been used as an alternative for hot rods, as run in the West Country during the late 1960s to the mid 1970s, and a Production car world championship race was held twice in the 1970s, won by Spence Morgan in 1974 and Ralph Sanders in 1975, both driving Ford Anglias.

It contained a large chapter on caliber, construction, production and properties of rockets ( for both military and civil purposes ), including multi-stage rockets, batteries of rockets, and rockets with delta wing stabilizers ( instead of the common guiding rods ).

Modern design and fabrication techniques, along with advanced materials such as graphite, boron and fibreglass composites as well as stainless steel ( see Emmrod )- have allowed rod makers to tailor both the shape and action of fishing rods for greater casting distance, accuracy, and fish-fighting qualities.

At best, they allow you to compare the quality of the material used to build different rods by the same manufacturer: an IM7 rod would use better graphite than an IM6 rod if both are made by the same manufacturer.

As of both IM and modulus, the higher rating, the lighter and more sensitive the rod is, however such rods also become more brittle due to time and usage.

At these light levels, both the rods and cones are actively contributing pattern information to that exiting the eye.

Some 4-barrel carburetors use metering rods only on the primary two venturis, but some use them on both primary and secondary circuits, as in the Rochester Quadrajet.

The main job of the lower class is heatsinking, where workers supervise the conversion of heat from the planet's core directly into electric power by sinking extremely long rods into the inner core of the planet ( the three other major sources of electric power were hydroelectric dams on the underground rivers, fusion energy, and solar energy from Trantor's sun, both from rooftop solar arrays and from solar energy satellites orbiting Trantor that beamed microwave energy to the surface ); ' heatsinkers ' were generally looked down upon by other Dahlites.

This is because both rods and cones are active at once in the eye, with each having different sensitivity spectra and rod photoreceptor cells taking over gradually from cone cells as the brightness of the scene is reduced.

Unlike V-twins, straight-twin engines do not use a common crank pin for both connecting rods, each cylinder has its own crank pin.

Their dominant mineral, sanidine feldspar, very commonly occurs in two generations, i. e. both as large well-shaped porphyritic crystals and in smaller imperfect rods or laths forming a finely crystalline groundmass.

Between these regions, mesopic vision comes into play and both rods and cones provide signals to the retinal ganglion cells.

In PWRs, the control rods are held above a reactor's core by electric motors against both their own weight and a powerful spring.

In both the PWR and the BWR there are secondary systems ( and often even tertiary systems ) that will insert control rods in the event that primary rapid insertion does not promptly and fully actuate.

The fathers of both Joseph Smith, Jr. and Oliver Cowdery were reported to have used divining rods, though not by those within the LDS church.

PAN is first thermally oxidized in air at 230 degrees to form PANOX and then carbonized above 1000 degrees in inert atmosphere to make carbon fibers found in plenty of both high-tech and common daily applications such as civil and military aircraft primary and secondary structures, missiles, solid propellant rocket motors, pressure vessels, fishing rods, tennis rackets, badminton rackets & high-tech bicycles.

Most other mammals are currently thought to be dichromats, with only two types of cone ( though limited trichromacy is possible at low light levels where the rods and cones are both active ).

Sticks ( or " rods ") are slotted on each end, both to provide some " give " when inserted into snug-fitting holes, and to allow thin cards, flags, and strings to be inserted into the slots.

* Cone monochromacy is the condition of having both rods and cones, but only a single kind of cone.

A rather far-flung example of inclusio in the Book of Jeremiah can be found in its first section, chapters 1 – 24, which are enveloped both by a similar question in the first and last episode ( 1: 11, 24: 3 ), and by similar imagery — that of almond rods and baskets of figs.

Although activation in both rods and cones has been found to persist beyond the physical offset of a stimulus, the rod system persists longer than cones.

Gothabilly and psychobilly both enjoy the sound of the double bass and share interests in B-rated horror movies, kitsch, hot rods ( especially hearses ), vintage fashion, the macabre and all things noir.

According to Al-Jalalan, the relics in the Ark were the fragments of the two tablets, rods, robes, shoes, mitres of Moses and the vase of manna.

They gained a second hearing with Pharaoh and changed Moses ' rod into a serpent, but Pharaoh's magicians did the same with their rods.

With this staff Aaron and Moses performed all the miracles related in Scripture, noteworthy among which was the swallowing up of the wonder-working rods of the Egyptian Posdi.

Illustration of the rods of Aaron and the magicians becoming snakes.

Videos of rod-shaped objects moving quickly through the air were claimed by some to be alien life forms or small UFOs, but subsequent experiments showed that these rods appear in film because of an optical illusion / collusion ( especially in interlaced video recording ).

After attending one such lecture, UFO investigator Robert Sheaffer wrote " Some of his “ rods ” were obviously insects zipping across the field at a high angular rate.

Huge nets were set up and the same surveillance cameras then captured images of rods flying into the trap.

When the nets were inspected, the " rods " were no more than regular moths and other ordinary flying insects.

Prior to the invention of tension rods drum skins were attached and tuned by rope systems such as that used on the Djembe or pegs and ropes such as that used on Ewe Drums, a system rarely used today, although sometimes seen on regimental marching band snare drums.

Thales ' experiments with amber rods were the first studies into the production of electrical energy.

The fasces, which consisted of a bundle of rods that were tied around an axe, was an ancient Roman symbol of the authority of the civic magistrate.

When England switched to the shorter foot in the late 13th century, rods and furlongs remained unchanged, since property boundaries were already defined in rods and furlongs.

This was unsatisfactory to Anderson, and the papier-mâché heads were replaced with hollow fibre glass heads with rods inside which could move the eyes — though the puppets could not blink — and wires which with a 12 volt current could move the mouths.

These first engines were used to power pumps and produced only reciprocating motion to move the pump rods at the bottom of the shaft.

Motive power came from the tank's own tracks which were connected by rods to a propeller shaft running through each float.

The West Country Production Cars were later reclassified as hot rods to come in line with the country's other promoters although this causes some confusion with the history of the West country racing as there was another class called Hot Rods that ran on those tracks.

In pankration competitions, referees were armed with stout rods or switches to enforce the rules.

In 1795, Nicholas Jacques Conté discovered a method of mixing powdered graphite with clay and forming the mixture into rods that were then fired in a kiln.

The bones were found using metal detectors and metal rods as probes.

In particular, fuel rods were developed at the Rocky Flats Plant, and twenty rockets were tested at the Nuclear Reactor Development Station, which was located at Jackass Flats within the Nevada Test Site.

During the First World War, screw pickets were used for the installation of wire obstacles ; these were metal rods with eyelets for holding strands of wire, and a corkscrew-like end that could literally be screwed into the ground rather than hammered, so that wiring parties could work at night near enemy soldiers and not reveal their position by the sound of hammers.

Negative numbers first appeared in the Nine Chapters on the Mathematical Art as black counting rods, where positive numbers were represented by red counting rods.

(" Sausage poisoning " was a common problem in 18th and 19th century Germany, and was most likely caused by botulism ) However, isolates from subsequent outbreaks were always found to be anaerobic spore formers, so Ida Bengston proposed that the organism be placed into the genus Clostridium as the Bacillus genus was restricted to aerobic spore-forming rods.
