Antoine Marc Gaudin (August 8, 1900 – August 23, 1974) was a metallurgist who laid the foundation for understanding the scientific principles of the froth flotation process in the minerals industry. He was also a professor at the Massachusetts Institute of Technology, and during World War II developed there the ore-processing techniques needed to extract uranium from its low grade ores for the Manhattan Project.

21st-century Bengalis
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, a ...

Bengali Hindus
Bengali Hindus ( bn, বাঙ্গালী হিন্দু/বাঙালি হিন্দু, translit=Bāṅgālī Hindu/Bāṅāli Hindu) are an ethnoreligious population who make up the majority in the Indian states of West Bengal, Tripura, Andaman and Nicobar Islands, Jharkhand, and Assam's Barak Valley region. In Bangladesh, they form the largest minority. They are adherents of Hinduism and are native to the Bengal region in the eastern part of the Indian subcontinent. Comprising about one-thirds of the global Bengali population, they are the second-largest ethnic group among Hindus after Hindustani Hindus. Bengali Hindus speak Bengali, which belongs to the Indo-Aryan language family and adhere to Shaktism (majority, the Kalikula tradition) or Vaishnavism (minority, Gaudiya Vaishnavism and Vaishnava-Sahajiya) of their native religion Hinduism with some regional deities. There are significant numbers of Bengali-speaking Hindus in different Indian states. Aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Engineers
The Indian Army Corps of Engineers is a combat support arm which provides combat engineering support, develops infrastructure for armed forces and other defence organisations and maintains connectivity along the borders, besides helping the civil authorities during natural disasters. College of Military Engineering, Pune (CME) is the premier technical and tactical training institution of the Indian Army Corps of Engineers. The Corps consists of three groups of combat engineers, namely the Madras Sappers, the Bengal Sappers and the Bombay Sappers. It has a long history dating back to the mid-18th century. The earliest existing subunit of the Corps (18 Field Company) dates back to 1777 while the Corps officially recognises its birth as 1780 when the senior-most group of the Corps, the Madras Sappers were raised. A group is roughly analogous to a brigade of the Indian infantry, each group consisting of a number of engineer regiments. The engineer regiment is the basic combat enginee ...

Eugène Lafont
Eugène Lafont, S.J. (26 March 1837 in Mons, Hainaut, Belgium – 10 May 1908 in Darjeeling, British India), was a Belgian Jesuit priest, who became a missionary in India, where he became a noted scientist and the founder of the first Scientific Society in India. Formation and early years He was born in Mons, where his father, Pierre Lafont, a military officer, was stationed. After secondary studies in the Jesuit Collège de Sainte-Barbe in his town, in 1854 Lafont was received into the novitiate of the Society of Jesus, located in the former Norbertine Abbey of Tronchiennes in Ghent. He then went through the usual Jesuit formation, spending his period of Regency teaching in Jesuit schools in Ghent (1857–59) and Liège (1862–63), followed by his studying to obtain degrees in both philosophy in Tournai and the natural sciences in Namur (1863–65). In Namur he showed a particular aptitude for physical experimentation. Service in India St. Xavier's College In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contact Angle
The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique equilibrium contact angle. However, in practice a dynamic phenomenon of contact angle hysteresis is often observed, ranging from the advancing (maximal) contact angle to the receding (minimal) contact angle. The equilibrium contact is within those values, and can be calculated from them. The equilibrium contact angle reflects the relative strength of the liquid, solid, and vapour molecular interaction. The contact angle depends upon the medium above the free surface of the liquid, and the nature of the liquid and solid in contact. It is independent of the inclination of solid to the liquid surface. It changes with surface tension and hence with the temperature and purity of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
