The Paper records the occurrence of large sired proto, single shell and Multi-Shell orbicular structures from the Bundelkhand Granitoid Complex. The orbicular structures are developed in an aplitic granite traversing the coarse grained link granite exposed to the SSW of village Kutawali (24°07'45'': 78°10'20") in pichhore Tehsil of Shivpuri district, Madhya Pradesh. The Core and matrix of the orbicules have identical composition and hence the orbicular structures are classified under Homo-Thrausmatic and Iso-Thrausmatic category. The chemical analyses of the orbicular rocks plot in the Quartz-Monzbnite field in Na2O-K2O and K2O-Na2O-CaO diagram. The composition of the orbicules represents a felsic Parentage: Per!thitic,intergrowth points to the igneous origin of the orbicular structures.Keywords

Legumes constitute an important source of dietary protein of large segments of the world's population particularly in those countries in which the consumption of animal protein is limited by its non-availability or is denied because of religious or cultural habit. In the present investigation five new varieties of Cajanus cajan (Arhar) have been analysed for their general composition.- Ultrasonic Wave Propagation through Calcium Oxide Single Crystal in High Temperature Range

The calcium oxide crystal possesses well developed fcc structure and is divalent in nature. Oxides and silicates make up the bulk of the Earth's mantle and crust, and thus it is important to predict their behavior for the study of seismic and volcanic activities. The second order elastic constants (SOECs) were computed using Coulomb and Born-Mayer potential in the temperature range 100-1000 K. The ultrasonic velocities were calculated using these values of second order elastic constants and density ρ. In this study temperature dependent velocities in calcium oxide have been calculated along <100>, <110> and <111> crystallographic directions and the results are presented graphically and discussed in depth.Keywords

An effort has been made for obtaining the second order elastic constants of rocksalt structure solids starting from primary physical parameters viz. nearest neighbour and hardness parameter assuming long- and short-range potentials at an elevated temperature. When the values of the second order elastic constants are known for a crystal, many of the anharmonic properties of the crystal can be treated within the limit of the continuum approximation in quantitative manner. The ultrasonic velocity any crystal is directly related to their second order elastic constants (v-longitudianal=(C11/d)1/2, v-shear=(C44/d)1/2;d is density). In this study, second order elastic constants are computed upto their melting temperature for rocksalt structure solids, which are alkali cyanides, sodium and potassium halides. The results thus obtained are compared with experimental data and found in well agreement with present values.- Report on National Symposium on Ultrasonics (XIII-NSU 2004): 21-23 December, 2004, Jhansi

The 13th National Symposium on Ultrasonics (XIII NSU 2004) was organized jointly by Department of Physics, Bundelkhand University, Jhansi and Ultrasonics Society of India (USI), National Physical Laboratory, New Delhi during December 21-23, 2004. The Symposium was an effort to bring to-gather all active researchers, users of Ultrasonics and Industrialists engaged in manufacturing ultrasonic equipments. Dr. Krishan Lai, Former Director, NPL inaugurated the Symposium. The inaugural session was presided over by Prof. P.S. Bisen, Dean, Academic Development & Planning, Bundelkhand University, Jhansi. Dr. Krishan Lal, President of USI released the Souvenir. Dr. S.K. Shrivastava gave the welcome address. Dr Krishan Lai, Prof. P.S. Bisen addressed the delegates and other invitees. Dr Janardan Singh, General Secretary, USI also addressed and spoke on the activities of USI and introduction about XIII-NSU 2004. Dr. Kailash, Co-convener, gave the vote of thanks. Beautiful mementoes were also presented to the Guests in the inaugural function. In spite of very cold weather, large number of participants participated from different parts of the country.- Insects for food, feed, pharmaceuticals and therapy: need for development
