Engineering In India
From pre-historic to modern times, engineering has played an essential role in the development of India. History Engineering in the country dates back to pre-historic times. Solar drying of agricultural commodities has been dated to a period of 6,000 BCE. Researchers have also found the evidences of engineering in Indus Valley civilization, dating back to 4th millennium BCE. Types of engineering such as Irrigation engineering, Transportation engineering were also established during this period. Throughout the period 3000 BCE – 1500 BCE, urban cities developed and included advanced developments for that time, such as brick houses, drainage systems, water harvesting, sanitation systems, etc. Vedas contains the information on about wells, irrigation, dams, canals, and other factors of engineering. By the period of 1,800 BCE, India had started to produce iron. In 500 BCE, Damascus steel was being produced in the country. Kallanai Dam, also known as Grand Anicut of Tamil Nadu ...

Solar Dryer
Solar dryers are devices that use solar energy to dry substances, especially food. Solar dryers use the heat from sun to remove the moisture content of food substances. There are two general types of solar dryers: Direct and indirect. Direct Direct solar dryers expose the substance to be dehydrated to direct sunlight. Historically, food and clothing was dried in the sun by using lines, or laying the items on rocks or on top of tents. In Mongolia cheese and meat are still traditionally dried using the top of the ger (tent) as a solar dryer. In these systems the solar drying is assisted by the movement of the air (wind) that removes the more saturated air away from the items being dried. More recently, complex drying racks and solar tents were constructed as solar dryers. One modern type of solar dryer has a black absorbing surface which collects the light and converts it to heat; the substance to be dried is placed directly on this surface. These driers may have enclosures, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indus Valley Civilization
The Indus Valley Civilisation (IVC), also known as the Indus Civilisation was a Bronze Age civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form 2600 BCE to 1900 BCE. Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread. Its sites spanned an area from much of Pakistan, to northeast Afghanistan, and northwestern India. The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan. The term ''Harappan'' is sometimes applied to the Indus civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province o ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Transportation Engineering
Transportation engineering or transport engineering is the application of technology and scientific principles to the planning, functional design, operation and management of facilities for any mode of transportation in order to provide for the safe, efficient, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods transport. The planning aspects of transportation engineering relate to elements of urban planning, and involve technical forecasting decisions and political factors. Technical forecasting of passenger travel usually involves an urban transportation planning model, requiring the estimation of trip generation (number of purposeful trips), trip distribution (destination choice, where the traveler is going), mode choice (mode that is being taken), and route assignment (the streets or routes that are being used). More sophisticated forecasting can include other aspects of traveler decisions, including auto ownership, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vedas
upright=1.2, The Vedas are ancient Sanskrit texts of Hinduism. Above: A page from the '' Atharvaveda''. The Vedas (, , ) are a large body of religious texts originating in ancient India. Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism. There are four Vedas: the Rigveda, the Yajurveda, the Samaveda and the Atharvaveda. Each Veda has four subdivisions – the Samhitas (mantras and benedictions), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic-sacrifices), the Brahmanas (commentaries on rituals, ceremonies and sacrifices), and the Upanishads (texts discussing meditation, philosophy and spiritual knowledge).Gavin Flood (1996), ''An Introduction to Hinduism'', Cambridge University Press, , pp. 35–39A Bhattacharya (2006), ''Hindu Dharma: Introduction to Scriptures and Theology'', , pp. 8–14; George M.

Damascus Steel
Damascus steel was the forged steel of the blades of swords smithed in the Near East from ingots of Wootz steel either imported from Southern India or made in production centres in Sri Lanka, or Khorasan, Iran. These swords are characterized by distinctive patterns of banding and mottling reminiscent of flowing water, sometimes in a "ladder" or "rose" pattern. Such blades were reputed to be tough, resistant to shattering, and capable of being honed to a sharp, resilient edge. Wootz (Indian), Pulad (Persian), Fuladh (Arabic), Bulat (Russian) and Bintie (Chinese) are all names for historical ultra-high carbon crucible steel typified by carbide segregation. "Wootz" is an erroneous transliteration of "utsa" or "fountain" in Sanskrit, however since 1794 it has been the primary word used to refer to historical hypereutectoid crucible steel. History Origins The origin of the name "Damascus Steel" is contentious: the Islamic scholars al-Kindi (full name Abu Ya'qub ibn Ishaq al-K ...

Cooper's Hill College
The Royal Indian Engineering College (or RIEC) was a British college of Civil Engineering run by the India Office to train civil engineers for service in the Indian Public Works Department. It was located on the Cooper's Hill estate, near Egham, Surrey. It functioned from 1872 until 1906, when its work was transferred to India. The college was colloquially referred to as Cooper's Hill and I.C.E. College (I.C.E. being an acronym for Indian Civil Engineering). History A Public Works Department was created in India in 1854, with responsibility for the construction of roads, canals and other civil engineering projects. It experienced difficulties in recruiting suitably qualified staff from the United Kingdom, and in 1868 a scheme was proposed for a dedicated training college in England. The chief advocate of this scheme, and effective founder of the college, was Sir George Tomkyns Chesney. The India Office bought the Cooper's Hill estate for £55,000 in 1870; and the college was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British India
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods: *Between 1612 and 1757 the East India Company set up Factory (trading post), factories (trading posts) in several locations, mostly in coastal India, with the consent of the Mughal emperors, Maratha Empire or local rulers. Its rivals were the merchant trading companies of Portugal, Denmark, the Netherlands, and France. By the mid-18th century, three ''presidency towns'': Madras, Bombay and Calcutta, had grown in size. *During the period of Company rule in India (1757–1858), the company gradually acquired sovereignty over large parts of India, now called "presidencies". However, it also increasingly came under British government over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
