Now a day's adulteration with a cheaper counterpart in commercial herbal medicine is very much common. It is impossible to identify the type of adulterants morphologically. So it is very important to have a method by which we can identify such types of adulteration in herbal medicine. One of the very promising methods that are known is DNA barcoding by which we can resolve such issues very easily. In this book, we try to authenticate the use of the ITS2 region as a suitable candidate marker to be used as DNA barcoding.

This book highlights recent advances in thin-film photonics, particularly as building blocks of metamaterials and metasurfaces. Recent advances in nanophotonics has demonstrated remarkable control over the electromagnetic field by tailoring the optical properties of materials at the subwavelength scale which results in the emergence of metamaterials and metasurfaces. However, most of the proposed platforms require intense lithography which makes them of minor practical relevance. Stacked ultrathin-films of dielectrics, semi-conductors, and metals are introduced as an alternative platform that perform unique or similar functionalities. This book discusses the new era of thin film photonics and its potential applications in perfect and selective light absorption, structural coloring, biosensing, enhanced spontaneous emission, reconfigurable photonic devices and super lensing.?

History is a popular optional subject in Civil Services Mains Examination and Allied Civil Services. History Optional includes a compulsory question of 50 marks on map entries in Paper-I.

It requires ample amount of precious time and energy for these tasks. ?Map Entries for History Optional? 2nd edition contains more than 450 map entries with descriptive notes, in a concise and lucid form. The book will properly cater to the requirements of the candidates to score high marks in History Optional. Salient features: - Specific focus on the civil services examination - Over 450 entries related to historical map entries - Precise, informative write-up on each entry - Solved Questions from 2013 to 2019.

Distillery effluent is one of the most difficult waste products to dispose of because of its low pH and dark brown colour. Colour removal of industrial effluents has been a major concern in wastewater treatment, especially for wastewater that originates from distilleries with a continuous discharge of a big quantity of coloured compounds. The efficient treatment of the effluent in an eco-friendly way is the need of the hour.In the present investigation, an attempt was made to isolates, screen and select the efficient fungal strains for distillery effluent decolourization. The various physicochemical and nutritional parameters were optimized for maximum decolourization of melanoidin by the selected fungus. A total of 3 fungi were isolated from the soil of the nearby area of the contamination site. All these isolates were initially screened for their potential to decolourization melanoidin. Out of these one best fungal isolate was further studied for decolourization of melanoidin in a different parameter. It was found to be by the addition of carbon and nitrogen sources, the best carbon was starch and nitrogen source was peptone, optimum pH for the growth of the fungus was found to be 5.0 were as optimum temperature was 37oC, best growth of the fungus was recorded in 120 hrs of incubation.
