Pinnate is a term used to describe feather-like or multi-divided features arising from both sides of a common axis in plant or animal structures, and comes from the Latin word pinna meaning “feather”, “wing” or “fin”. A similar term is pectinate, which refers to a comb-like arrangement of parts. The term contrasts somewhat with palmate, in which the parts or structures radiate out from a common point.

COLEUS LEAVES
Solenostemon is a genus of perennial plants, native to tropical Africa, Asia, Australia, the East Indies, The Malay Archipelago, and the Philippines. They are commonly known as Coleus, a name which derives from an earlier classification under the genus name coleus, species of which are currently included in either solenostemon or another genus, Plectranthus.
VENUS FLYTRAP
The Venus Flytrap, Dionaea muscipula, is a carnivorous plant that catches and digests animal prey – mostly insects and arachnids. Its trapping structure is formed by the terminal portion of each of the plant’s leaves and is triggered by tiny hairs on their inner surfaces. When an insects or spider crawling along the leaves comes into contact with one or more of the hairs twice in succession, the trap closes. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value.

CANTILEVER BRIDGE
A cantilever bridge is a bridge built using cantilevers, structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
CABLE-STAYED BRIDGE
A cable-stayed bridge is a bridge that consists of one of more columns, with cables supporting the bridge deck.
There are two major classes of cable-stayed bridges: In a harp design, the cables are made nearly parallel by attaching cables to various points on the towers so that the height of attachment of each cable on the tower is similar to the distance from the tower along the roadway to its lower attachment. In a fan design, the cables all connect to or pass over the top of the towers.
BOX GIRDER BRIDGE
A box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport.
JUSCELINO KUBITSCHEK BRIDGE
The Juscelino Kubitschek Bridge, also known as the President JK Bridge or just the JK Bridge, crosses Lake Paranoa in Brasilia, D.F.

It was designed by architect Alexandra Chan and structural engineer Mario Vila Verde.

WADI LEBAN BRIDGE
SALGINATOBEL BRIDGE
Salginatobel Bridge is a reinforced concrete arch bridge designed by renowned Swiss civil engineer Robert Maillart. It was constructed across an alpine valley in Schiers, Switzerland between 1929 and 1930. In 1991, it was declared an International Historic Civil Engineering Landmark, the thirteenth such structure and the first concrete bridge so dedicated.
SAFAVID BRIDGE
OCTAVIO FRIAS DE OLIVEIRA BRIDGE
The Octavio Frias de Oliveira bridge is a cable stayed bridge in Sao Paulo, Brazil over the Pinheiros River, opened in May 2008. The bridge is 138 metres (450 ft) tall, and connects Marginal Pinheiros to Jornalista Roberto Marinho Avenue.
The bridge deck is unusual due to its form, which is similar to an “X”, crossing at the tower.
AKASHI-KAIKYO BRIDGE
The Akashi-Kaikyo Bridge, also known as the Pearl Bridge, is the world’s longest suspension bridge. It is located in Japan and was completed in 1998. The bridge links the city of Kobe on the mainland of Honshu to lwaya on Awaji Island by crossing the busy Akashi Strait. It carries part of the Honshu-Shikoku Highway.

GOOSE BIRD
Goose (Plural: Geese) is the English name for a considerable number of birds, belonging to the family Anatidae. This family alos includes swans, most of which are larger than true geese, and ducks, which are smaller.
A number of other waterbirds, mainly related to the shelducks, have “goose” as part of their name.

SWANS
Swans, genus Cygnus, are birds of the family Anatidae, which also includes geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six to seven species of swan in the genus Cygnus; in addition there is another species known as a swan, the Coscoroba Swan, although this species is no longer considered related to the true swans. Swans usually mate for life, though ‘divorce’ does sometimes occur, particularly following nesting failure. The number of eggs in each clutch ranges from three to eight.
DUCK
Duck is the common name for a number of species in the Anatidae family of birds. The ducks are divided between several subfamilies listed in full in the Anatidae article; they do not represent a monophyletic group but a form taxon, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, mostly smaller than the swans and geese, and may be found in both fresh water and sea water.
Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots.
HILL BIRD
The Indian Himalayas stretches from Kashmir in the west to Arunachal Pradesh in the east. It crowns the country in the north with the highest and most foreboding mountain range in the world. The altitude differences coupled with climatic diversity and heavy rainfall make the Himalaya an unique home for some of the most beautiful and sought after birds in the world.
SANTRAGACHI BIRDS
Just a 20 minute drive from the center of Kolkata lies a 13,75,000 square feet lake, known as the Santragachi Jheel. Winter months (October to March) draw 4000 to 5000 ducks and moorhens to this safe haven.
Santragachi is not beautiful. It is hemmed in by habitation and railway tracks. Water hyacinth covers a large part of the surface and there is very little green cover. But the birds more than make up in their variety, numbers and in the unconcerned way they make Santragachi a home.

DIAMONDBACK WATER SNAKE
The Diamond back Water Snake is a common species of water snake found throughout much of the cenral United States and northern Mexico. It is non-venomous and a member of the colubrid family. There are three recognized subspecies of N. Rhombifer. The species was first described as Tropidonotus rhombifera by Edward Hallowell in 1852.
BURROWING SNAKES
Burrowing snakes live underground. Of course, there are also other snakes that go underground to escape the heat of the sun and to hide from predators. But burrower’s are the only ones that can dig their own holes. The other has to depend on the holes made by crabs, rats and termites. The burrowing snake’s skull is as powerful as the point of a crowbar. Its stocky body and strong neck muscles make it easy for the snake to bulldoze its way through soft soil. The species from the hills are so dependent on remaining cool that they often die in a human hand (which usually has a temperature of about 37ยบ C).
