A Merge sign may be used to warn road users on the major roadway that merging movements might be encountered in advance of a point where lanes from two separate roadways converge as a single traffic lane and no turning conflict occurs. A Merge sign may also be installed on the side of the entering roadway to warn road users on the entering roadway of the merge condition. The Merge sign should be installed on the side of the major roadway where merging traffic will be encountered and in such a position as to not obstruct the road user's view of entering traffic.

Each detour shall be adequately marked with standard temporary route signs and destination signs. Detour signs in TTC incident management situations may have a black legend and border on a fluorescent pink background. The DETOUR sign should be used for unnumbered highways, for emergency situations, for periods of short durations, or where, over relatively short distances, road users are guided along the detour and back to the desired highway without route signs. A Street Name sign should be placed above, or the street name should be incorporated into, a DETOUR sign to indicate the name of the street being detoured.

Paradoxides was a genus of relatively large trilobites, extinct marine arthropods, that form the class Trilobita found throughout the world during the Mid Cambrian period (540 million years ago). It was a moderately large trilobite with a semicircular head, free cheeks each ending with a long, narrow, recurved spine, and relatively large eyes. Its elongated trunk was composed of 20 segments and again was adorned with longish, recurved lateral spines. Its pygidium(caudal shield) was comparatively small and had one or two pairs of long spines on the posterior margin.

Hydroids, related to the jellyfish, have three basic life-cycle stages: a tiny free-swimming planula larva, which settles and grows into a sessile attached, usually colonial hydroid stage, which in turn liberates medusae.

Flatworms are flattened, leaf-like forms living in damp places on land, in freshwater streams of ponds, or along the seacoast while a variety of other species are parasitic. The free forms are usually small, barely reaching a length greater than five or seven cetimeters (2 to 3 inches). Some of the parasitic species attain the great length of six to thirteen meters (20 to 40 feet). This is a fresh water flatworm.

Marine worms (Polynoe bevisetosa), a worm with highly developed heads and many bristles arranged along the sides of the body. These are common form along the seashore. The body presents the same segmented apprerance as the earthworm. The head is provided with numerous sense organs, among which are four eyes and several tentacles or feelers. Shown is a common marine worm with extended proboscis and overlapping plated covering the back.

Many mollusks live upon seaweeds, and the greater number of terrestrial forms are fond of garden vegetables. The food needs to be masticated and the mouth is usually provided with horny jaws, and an additional matricatory apparaus which consists of a kind of tongue with eight to forty thousand minute teeth in our land forms, while in certain marine snails they are beyond computation. With the licking motion of the tongue this rasp tears the food into shreds before it is swallowed. Shown here is a small portion of the radula or tongue-rasp of a snail.

A barnacle is a type of arthropod belonging to infraclass Cirripedia in the subphylum Crustacean, and is hence distantly related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile suspension feeders, and have two nektonic larval stages. Barnacles are encrusters, attaching themselves permanently to a hard substrate. Shown is a barnacle larva.

Cockroaches or roaches are insects of the order Blattaria. This name derives from the Latin word for "cockroach", blatta. Cockroaches live in a wide range of environments around the world. Pest species of cockroaches adapt readily to a variety of environments, but prefer warm conditions found within buildings. Many tropical species prefer even warmer environments and do not fare well in the average household. Roaches are not able to survive in moist areas such as bathrooms and are not able to exit such areas. This diagram shows a dissection of a cockroach with particular note of the allmentary canal (al).

Scorpions are any arachnid of the order Scorpionida. Unlike the majority of arachnid species, scorpions are viviparous. The young are born one by one, and the brood is carried about on its mother's back until the young have undergone at least one moult. All known Scorpion species possess poison or venom. Scorpions use their venom to kill or paralyze their prey so that it can be eaten; in general it is fast-acting, allowing for effective prey capture.

Bees are flying insects closely related to wasps and ants. Honey bees (or honeybees) are a subset of bees, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. A colony generally contains one queen bee, a fertile female; seasonally up to a few thousand drone bees or fertile males; and a large seasonally variable population of sterile female worker bees. Workers gather pollen into the pollen baskets on their back legs, to carry back to the hive where it is used as food for the developing brood.

Carpenter bees are large, hairy bees distributed worldwide. Their name comes from the fact that nearly all species build their nests in burrows in dead wood, bamboo, or structural timbers. In several species, the females live in tunnels alongside their own daughters or sisters, creating a sort of social group. They use wood bits to form partitions between the cells in the nest. A few species bore holes in wood dwellings. Since the tunnels are near the surface, structural damage is generally minor or nonexistent.

"U.S. Rifle, CAL .30 M1903 (Springfield)." -War, 1944 The Springfield M1903, formally the United States Rifle, Caliber .30, Model 1903, is an American magazine-fed, bolt-action rifle used primarily during the first half of the 20th century. It was officially adopted as a United States military service rifle on June 19 1903, and saw service in World War I. It was officially replaced as the standard infantry rifle by the faster-firing, semi-automatic M1 Garand, starting in 1936.

The Browning M1919 is a .30 caliber medium machine gun family widely used during the 20th century. It was used as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries, especially during World War II, the Korean War, and the Vietnam War. Although it began to be superseded by newer designs in the later half of the century (such as by the M60 machine gun), it remained in use in many North Atlantic Treaty Organization (NATO) countries and elsewhere for much longer. It is very similar in design to the larger .50-caliber M2 Machine Gun, which is also a Browning-designed weapon and is still in NATO service.

A bazooka is one of a series ("M9 series" variants) of anti-armor and anti-bunker, man-portable rocket launchers that became famous during World War II. Technically named as the M9 Anti-tank Rocket Launcher, it was also called "stovepipe" and used to deliver high explosives into machine gun nests and hardened bunkers in all World War II theaters. It was one of the primary infantry anti-tank weapons used by the United States Armed Forces.

The 105 mm Howitzer M2A1(M101) was the standard light field howitzer for the United States in World War II, seeing action in both European and Pacific theatres. Entering production in 1941, it quickly entered the war against the Imperial Japanese Army in the Pacific, where it gained a reputation for its accuracy and powerful punch. The M101 fired 105 mm high explosive (HE) semi-fixed ammunition and had a range of 11,200 metres (12,200 yd), making it suitable for supporting infantry.
