The Formation of Dalit Sensibility in Dalit Literature Kusum Lata*Surekha Dangwal** In Indian society there exists a hierarchical ordering of people called Varna System which refers to “a notional all India fourfold division of society into estates based on function” and each individual has a position in society according to this hierarchy laid out by the Law books of the classical period. The upper rung of this system is the ‘Brahmins’ followed by ‘Kshatriyas’ (Warriors) and ‘Vaishyas’ (Merchants)

purchase of KA oil (a mixture of cyclohexanone‚ the ketone or K component‚ and cyclohexanol‚ the alcohol or A component)‚ or of pure cyclohexanol‚ and its subsequent oxidation in solution to adipic acid using an excess of strong nitric acid. This report deals with KA oil/cyclohexanol production by various routes‚ followed by the common step of nitric acid oxidation. KA oil production from cyclohexane by the cobalt catalyst and boric acid air oxidation routes is reviewed. Production of KA oil from

Determination of Ka for a Weak Acid Introduction In the experiment preformed the objective is to titrate a weak acid with a strong base. In a titration of a weak acid with a strong base the titrant is the strong base and the analyte is a weak acid. The reaction that will occur is the direct transfer of protons from the weak acid to the hydroxide ion. The data gathered will be represented on the titration curve‚ a graph of the volume of titrant being the strong base plotted against the pH .The

Different forms of energy can be interconverted Examples: Light bulb: electrical energy is converted to light energy and heat energy Car engine: chemical energy (from gasoline) heat energy kinetic energy KINETIC ENERGY (Ek) · Definition: is the energy associated with a moving object · Formula: 2 Ek = ½ mv ‚ where m = mass of the moving object v = speed of the moving object (in kg) (in m/s) NOTE: Two objects moving at different speeds may have the same kinetic energy Example: slow moving truck and fast moving sports’ car

Parents always say that they want their children to follow their dreams‚ but that’s considered hypocritical when they don’t let their kids decided for themselves. In many cultures‚ the choice of education‚ job‚ and spouse is the parents’ decision and the children in question are expected to be obedient and learn to accept those decisions without requesting any other alternatives. The question is: how can these children obey their parents when they don’t get to live their own lives? In some rare situations

Ancient Egyptians had a strong belief in preserving the body for the afterlife in hopes of achieving immortality. Part of this preservation was to protect and identify the body by painting or carving pictures‚ hieroglyphics‚ and symbols on the coffin. One very good example of this is represented by the ‘Mummy of Irethorrou in Coffin.’ This coffin‚ made of wood with polychrome‚ is adorned with hieroglyphics‚ symbols‚ and a portrait of the Egyptian priest. It was found in a cemetery in Akhmim‚ and

II.The decline of the Ghaznavids and rise of the Seljuk empire‚ 1040-1200 it was a new dynasty that was no longer run by a caliphate or family member of a religious background it was run by the sultan. The relationship of the sultan and the caliph relationship started when the Turks entered Islam. The caliphate‚ was replaced by a new institution the sultan. The Turks were brought in to fight in the military by them either being slaves or adventurers. Through their service they became excellent soldiers

the acid ionization constant‚ Ka. The equation for Ka incorporates the concentration of water as a constant value. Ka = [ H3O+][A-] [HA] and Ka = Kd [H2O] Organic acid ionization constants can cumbersome to work with because they are often very small numbers. Acetic acid‚ for example‚ has a Ka is value of about 0.00001 (or 10-5)‚ phenol has a Ka of 10-10. It is usually more convenient to use a logarithmic scale to handle these numbers. Accordingly‚ Ka values are transformed to pKa values

1. Adsorption: Concentration of liquid or gaseous molecules over the surface of a solid material is known as adsorption. It is a surface phenomenon. (e.g.) H2 adsorption over nickel. The solid material is known as adsorbent. (e.g.) Nickel‚ Silica gel‚ Charcoal‚ Zeolite The gaseous or liquid molecules are adsorbate (e.g.) H2 gas‚ Bromine‚ benzene‚ water vapour For gases‚ a special name is given as “occlusion’ 2.If the concentration is of bulk phenomenon‚ it is absorption
