A significant part of the effort is dedicated to basic research. Reports on the outcome of basic research are often published in scientific journals or as technical reports. A part of the applied research also leads to journal articles and technical reports, but a significant part of the work in the field of applied research, especially those which have a direct bearing on the design, development and operation of nuclear power reactors, result in technical notes specifically addressed to the concerned agencies. The purpose of bringing out a consolidated BARC Progress Report on an yearly basis is to give a brief account of the work being done in BARC in a single document. Those who find any particular item of work of interest can refer to the detailed reports or papers listed in the list of references. I hope this compilation serves the purpose of giving a flavour of the entire gamut of R&D work being done in BARC. mil Kakodkar) fcm : (91 ) (22) 556 0750 , (91) (22) 556 0534 :011- 61017 *rt$*Tj4 61022*1*?* Gram : BARC • MUMBAI 85 Fax : (91 ) (22) 556 0750.

INTRODUCTION Although a considerable number of precipitants have been pro- posed for the determination of aluminium, direct precipitation of aluminium hydroxide by means of ammonium hydroxide, fol- lowed by ignition to oxide, is most commonly used, especially if no separation from iron is desired, in which latter case special methods must be employed. While the general principles involved in this determination are extremely simple, it has long been recog- nized that certain precautions in the precipitation, washing, and ignition are necessary if accurate results are to be obtained. While, however, most of these details have been studied and dis- cussed by numerous authors, it is noteworthy that few publica- tions or textbooks have taken account of all the factors. In the 515 ; 516 Bulletin of the Bureau of Standards [Voi.i3 present paper it seems desirable, therefore, to assemble the various recommendations and to consider their basis and their accuracy.

  • Sri Ramakrishna & His Disciples in Orissa
    Preface Pilgrimage places like Varanasi, Prayag, Haridwar and Vrindavan have always got prominent place in any pilgrimage of the devotees and its importance is well known. Many mythological stories are associated to these places. Though Orissa had many temples, historical places and natural scenic beauty spot, but it did not get so much prominence. This may be due to the lack of connectivity. Buddhism and Jainism flourished there followed by Shaivaism and Vainavism. After reading the lives of Sri Chaitanya, Sri Ramakrishna, Holy Mother and direct disciples we come to know the importance and spiritual significance of these places. Holy Mother and many disciples of Sri Ramakrishna had great time in Orissa. Many are blessed here by the vision of Lord Jagannath or the Master. The lives of these great souls had shown us a way to visit these places with spiritual consciousness and devotion. Unless we read the life of Sri Chaitanya we will not understand the life of Sri Ramakrishna properly. Similarly unless we study the chapter in the lives of these great souls in Orissa we will not be able to understand and appreciate the significance of these places. If we go on pilgrimage to Orissa with same spirit and devotion as shown by these great souls, we are sure to be benefited spiritually. This collection will put the light on the Orissa chapter in the lives of these great souls and will inspire the devotees to read more about their lives in details. This will also help the devotees to go to pilgrimage in Orissa and strengthen their devotion.

  • Alcl3(G)=3Alcl(G) Reaction in the Subhalide Process of Aluminium (Study of Extractive Metallurgy of Aluminium (1))
    Equilibrium of the 2Al(l)+AlCl3(g)=3AlCl(g) Reaction in the Subhalide Process of Aluminium (Study of Extractive Metallurgy of Aluminium (1)) By Takeaki Kikuchi*, Toshio Kurosawa* and Testuo Yagihashi* Equilibriumconstants of a fundamental reaction of the aluminium subhalide process, 2Al(l)+AlCl3(g)= 3AlCl(g), were determined by the flow method using argon carrier between 1000℃ and 1250℃. As a result of this experiment, equilibrium constants and standard free energy were obtained by the following equation: The heat of formation and entropy of AlCl(g) obtained from the experimental data and other thermodynamic values were -22,250cal/mot and 48.7cal/mol respectively. By the use of the equilibrium constants, the reaction ratio of aluminium trichloride was calculated at a reduced pressure and in argon carrier, respectively. (Receivedmarch 10, 1964) I.

  • Town Survey Report, Dhanbad, Part XB, Series-4, Bihar
    CENSUS OF INDIA 1981 PARTXB SERIES 4 BIHAR TOWN SURVEY REPORT DHANBAD Drafted by Rajendra Prasad Asstt. Director Edited by S.C. Saxena Deputy Director Supervised by V.K. Bhargava Deputy Director Directorate of Census Operations BIHAR FOREWORD Apart from the decennial enumeration of population, the Indian Census is ~teeped in the tradition of undertaking a variety of studies of topical interest. In fact, the publications brought out in connection with the earlier censuses contained veritable mines of informatfon!On racial, cultural, linguistic and a number of other aspects of life of the people of this country. With the advent of freedom, however, the scope and dimension of these special studies had to be re­ structured in a manner that would provide the basic feedbacks on the processes of development taking place in different spheres of life of the people especially under planned development. Thus, in connection with the 1961, Census, a massive programme wa~s launched inter-alia to conduct socio-economic survey of about 500 villages selected from different parts of the country. The main objective of this study was to know the way of life of the people living in Indian villages which accounted for 82 per cent of the total population as per the 1961 Census. There was, however, an imperative need to extand the area of the study to urban centres as well, to -provide a complete coverage of the people living in diverse sodo economic conditions. It was with this objective in view ancillary studies on towns were launched as part of the social studies programme in connection with the 1971 Census.
