It is also known as a dog-house dormer (due to its similar shape). Hip roof dormer Also called a hipped dormer, [6] it has a roof composed of three sloping planes that rise from each side of the dormer frame and converge at the ridge—analogous to the hip roof. Flat roof dormer The roof of this dormer is a single flat plane approximately ...

A thatched pub (The Williams Arms) at Wrafton, North Devon, England. Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (Cladium mariscus), rushes, heather, or palm branches, layering the vegetation so as to shed water away from the inner roof.
Being the first domesticated species by humans has created a strong bond between dogs and humans and entwined their histories. Dogs accompanied humans when they first migrated into new environments and show similar adaptations – such as to high altitude, low oxygen conditions. There is an extensive list of genes showing signatures of parallel ...
Digitigrades include birds (what many see as bird's knees are actually ankles), cats, dogs, and many other mammals, but not plantigrades (such as humans) or unguligrades (such as horses). Digitigrades generally move more quickly than other animals. Comparison of lower limb structure. From left to right: plantigrade, digitigrade and unguligrade.
A muzzle is a device that is placed over the snout of an animal to keep them from biting or otherwise opening their mouth. Muzzles can be primarily solid, with air holes to allow the animal to breathe, or formed from a set of straps that provides better air circulation and allow the animal to drink, and in some cases, eat.
The legs of water beetles have little hairs which spread out to catch and move water back in the power stroke, but lay flat as the appendage moves forward in the return stroke. Also, one side of a water beetle leg is wider than the others and is held perpendicular to the motion when pushing backward, but the leg rotates when the limb returns ...
In order to buttress the horizontal thrusts of a large hemispherical masonry dome, the supporting walls were built up beyond the base to at least the haunches of the dome and the dome was then also sometimes covered with a conical or polygonal roof. [10] A variety of other shapes, including shallow saucer domes, segmental domes, and ribbed ...
