Population modelA population model is a type of mathematical model that is applied to the study of population dynamics. Models allow a better understanding of how complex interactions and processes work. Modeling of dynamic interactions in nature can provide a manageable way of understanding how numbers change over time or in relation to each other. Many patterns can be noticed by using population modeling as a tool. Ecological population modeling is concerned with the changes in parameters such as population size and age distribution within a population.
Rain gardenRain gardens, also called bioretention facilities, are one of a variety of practices designed to increase rain runoff reabsorption by the soil. They can also be used to treat polluted stormwater runoff. Rain gardens are designed landscape sites that reduce the flow rate, total quantity, and pollutant load of runoff from impervious urban areas like roofs, driveways, walkways, parking lots, and compacted lawn areas.
Indian artIndian art consists of a variety of art forms, including painting, sculpture, pottery, and textile arts such as woven silk. Geographically, it spans the entire Indian subcontinent, including what is now India, Pakistan, Bangladesh, Sri Lanka, Nepal, and at times eastern Afghanistan. A strong sense of design is characteristic of Indian art and can be observed in its modern and traditional forms. The origin of Indian art can be traced to prehistoric settlements in the 3rd millennium BCE.
Commercial RevolutionIn European history, the Commercial Revolution saw the development of a European economy – based on trade – which began in the 11th century AD and operated until the advent of the Industrial Revolution in the mid-18th century. Beginning 1100 with the Crusades, Europeans rediscovered spices, silks, and other commodities then rare in Europe. Consumer demand fostered more trade, and trade expanded in the second half of the Middle Ages (roughly 1000 to 1500 AD).
History of IndiaAnatomically modern humans first arrived on the Indian subcontinent between 73,000 and 55,000 years ago. The earliest known human remains in South Asia date to 30,000 years ago. Sedentariness began in South Asia around 7000 BCE; by 4500 BCE, settled life had increasingly spread, and gradually evolved into the Indus Valley civilisation, which flourished between 2500 BCE and 1900 BCE in present-day Pakistan and north-western India. Early in the second millennium BCE, persistent drought caused the population of the Indus Valley to scatter from large urban centres to villages.
Indian rock-cut architectureIndian rock-cut architecture is more various and found in greater abundance in that country than any other form of rock-cut architecture around the world. Rock-cut architecture is the practice of creating a structure by carving it out of solid natural rock. Rock that is not part of the structure is removed until the only rock left makes up the architectural elements of the excavated interior. Indian rock-cut architecture is mostly religious in nature. There are more than 1,500 known rock-cut structures in India.
Architecture of RajasthanThe architecture of the Indian state of Rajasthan has usually been a regional variant of the style of Indian architecture prevailing in north India at the time. Rajasthan is especially notable for the forts and palaces of the many Rajput rulers, which are popular tourist attractions. Most of the population of Rajasthan is Hindu, and there has historically been a considerable Jain minority; this mixture is reflected in the many temples of the region.
Great RecessionThe Great Recession was a period of marked general decline observed in national economies globally, i.e. a recession, that occurred from late 2007 to 2009. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression. One result was a serious disruption of normal international relations.
Central business districtA central business district (CBD) is the commercial and business centre of a city. It contains commercial space and offices, and in larger cities will often be described as a financial district. Geographically, it often coincides with the "city centre" or "downtown". However, these concepts are not necessarily synonymous: many cities have a central business district located away from its commercial and or cultural center and or downtown/city center, and there may be multiple CBDs within a single urban area.
