Dhaka is the capital of Bangladesh and the principal city of Dhaka District. Dhaka is a Mega city and one of the major cities of the South Asia. Located on the banks of the Buriganga River, Dhaka, along with its metropolitan area, has a population of over 12 million, making it the largest city in Bangladesh.[1] With its colourful history, Dhaka is known as the 'City of Mosques' and for its famous fine Muslin cloth which has a great ethnic value. Under Mughal rule in the 17th century, the city was also known as Jahangir Nagar, and was both a provincial capital and a centre of the world-wide muslin trade. The modern city, however, was developed chiefly under British rule in the 19th century, and soon became the second-largest city in Bengal after Calcutta (presently Kolkata). With the partition of India in 1947, Dhaka became the administrative capital of East Pakistan, and later, in 1972, the capital of an independent Bangladesh. During the intervening period, the city witnessed widespread turmoil; this included many impositions of martial law, the declaration of Bangladesh's independence, military suppression, devastation during war, and natural calamities. Modern Dhaka is the centre of political, cultural and economic life in Bangladesh. Its urban infrastructure is the most developed in the country, it is nonetheless a fighting metropolitan city with challenges such as pollution, congestion, and lack of adequate services due to the rising population. In recent decades, Dhaka has seen modernisation of transport, communications and public works. The city is attracting large foreign investments and greater volumes of commerce and trade. It is also experiencing an increasing influx of people from across the nation. To fight rising traffic congestion and population rise in the capital city, the national government has implemented a policy for rapid urbanisation of surrounding areas and beyond by recent introduction of ten year tax on income holiday for new construction of all types of facilities and buildings outside Dhaka.

Rings

A finger ring is a circular band worn as a type of ornamental jewelry around a finger; it is the most common current meaning of the word ring. Other types of metal bands worn as ornaments called rings, such as arm rings and neck rings. Rings worn by both men and women and can be of any quality. Various ring shapes and styles exist. The following are but a few. Flat wedding bands are the simplest form of ring. A flat wedding band consists of a strip of metal bent around into a loop and joined where the ends meet. Half-round rings, also called D-shape rings, are flat wedding bands filed half-round on the outside. Sleeve rings are rings that consist of a thin inner ring or sleeve, with several other rings stacked onto it to form one solid ring. Either the rings soldered onto the sleeve or the ends of the sleeve can be upset to keep them all together. A little of both can also be done. Solitaire rings are rings with a single large stone as a centerpiece, usually a diamond. Eternity rings are rings with stones, usually diamonds, of the same cut and size, set in one row all around the ring. The stones are usually round or square, and the setting is usually either claws or a channel setting. When the stones do not continue around the entire ring, but stop halfway around the finger, it is a half-eternity ring. Trinity rings or Trilogy Rings are three rings worn at one time. Cluster rings are rings with a group of stones in a cluster setting, forming the focal point of the ring. The cluster setting usually consists of one large stone in the center surrounded with several smaller stones. Tension Rings are a type of ring in which a single gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone. In the United States and Canada, ring sizes specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch in diameter, or roughly 1/10 inch in inside circumference. Generally, sizes in quarters and halves will not relate conventionally to anything on any known ruler. On one finger alone, a person may vary more than a whole ring size- depending on time of day, work performed, and other swelling-inducing activities/conditions. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring.
