This book entitled as "Tribes in India and Tamil Nadu: Development and Education" has been written about the tribal development and educational programs with a case study of the Malayali tribe in Kalrayan Hills, Villupuram district, Tamil Nadu. This book consists of two parts. The first part covers Tribes in India and Tamil Nadu, Tribal development before and after Independence and deals with the various tribal development program of both the Central and State Government of India and their benefits. The second part covers Educational policies and supportive programmes by the department of education, a report on educational schemes on tribal.

"Job Satisfaction and Women Teachers" is a complete text -cum reference book for In-service teachers, teacher-educators and prospective teachers of all pedagogical institutes and department of education of different universities. The present book is designed to highlight the important aspects of the socio-economic conditions of the women teachers, the working conditions of women teachers and their problems, the attitude of the women teachers towards their economic and educational factors, the job satisfaction of women teachers with their level of education and some suggestions to evolve suitable recommendations for the better condition of women teachers.

Nanomaterials ferrites have applications in making permanent magnets, magneto optic displays, microwave absorbers, high density information devices, colour imaging etc. In the present investigation lithium ferrite and lithium vanadium ferrite are synthesized by sol-gel process. The x-ray diffraction results show that the structure of lithium ferrite and vanadium doped lithium ferrite are monoclinic structure. The average particle size of lithium ferrite is 22nm and vanadium doped lithium ferrite is 29nm are calculated by Scherer formula. The lattice parameters and dislocation density (δ) are calculated from XRD data. Strain (ε) values are evaluated from Williamson-Hall plot. The FT-IR study reveals the formation of ferrites showing the significant absorption bands. The VU-VIS spectroscopic data are used to calculate direct and indirect optical band gap (Eg) by using Tauc plot at the edge of the absorption band. They are determined to be 1.57eV &1.71eV, 1.01eV&1.01eV for lithium ferrite and lithium vanadium ferrite respectively. The energy dispersive x-ray analysis spectra showed that the expected elements exist in the material.
