Universality of Marriage

The debate is on the definition of the term marriage. There is barrier because of unimaginative variation in the institution of human marriage. Earlier definition is given by Westermarck, Malinowski and Radcliffe Brown and Murdock. Westermarck: Marriage is a relation of one or more men with one or more women which is recognized by custom or law and which involves certain rights and duties. This definition defies many ethnic situations such as male-male marriages,female-female marriages and sham marriages among kwukiutl Negroes. These cannot fit into this definition of marriage.Hence fails universal...

Safety measures incorporated in the Kudankulam Nuclear Power Plant

As a part of the endeavour to constantly improve the safety aspects of nuclear reactors and also from the past experiences such as the Fukushima nuclear accident in Japan, many safety measures have been incorporated in the Kudankulam Nuclear Power Plant (KKNPP). These include:- i. The VVER type reactor of KKNPP has been certified by the IAEA as one of the   safest nuclear reactors in the world having many inbuilt safety measures. It is a  third generation plus reactor unlike first generation reactors of Fukushima. ii. The site falls under Zone III of seismic zones and is unlikely...

Rehabilitation Robotics and its practical applications:

Rehabilitation robotics is a field of research dedicated to understanding and augmenting rehabilitation through the application of robotic devices. Rehabilitation robotics includes development of robotic therapies, and the use of robots as therapy aids instead of solely as assistive devices. Rehabilitation using robotics is generally well tolerated by patients, and has been found to be an effective adjunct to therapy in individuals suffering from motor impairments, especially due to stroke. Current robotic devices include exoskeletons for aiding limb or hand movement such as the Tibion Bionic...

Various techniques, which are employed to derive energy from the waste material.

Combustion or Incineration  It is direct burning of wastes in the presence of excess air (oxygen) at high temperatures(about 800 C).  It results in conversion of 65%-80% of heat content of organic matter into hot air, steam and hot water.   The steam generated can be used in steam turbines to generate power. Biomethanation or Anaerobic Bigestion  In this, the organic waste is segregated and fed into a biogas digester. The waste undergoes biodegradation under anaerobic conditions to produce methane rich biogas. The so produced biogas can be used for cooking, heating, generating...

Difference between Automation and Robotics.

1. Set operations and Sequence: Automation can only follow one set of operations, and it cannot be changed once programmed. Robots are made to perform several jobs at once, and the sequence of operations can be switched around to make the processes more efficient. The timing of the operations also can be changed in robotics, if needed. 2. Outside stimuli: The automated machine will not react; even if there is an object blocking the automation, it will continue doing the same operation. Robots are made to react so, if something blocks or stops the robot, it will change operations to best fit...
