Chanch Pottery is small industrial town on the bank of river Barakar.You will not find schools there. But plenty country wine shops are there around. During wages day it is common to see people are lying on the road being over drunk. Most of salary goes to wine shop & pocket of moneylender. Poverty, illiteracy, exploitation are common features of lives of natives of this area. River Barakar gets dried in summer, overflown during monsoon. But it does not change state of people staying by the side of river. People are born here to die in poverty. Badri Prasad,a colliery worker & trade union leader, decided to unsettle the settled fact. He challenged local mafia Ratnakar and advised other workers not to borrow money from him with high interest. Confrontation started. With the support of Leftist radical outfit Naxalites these tribals started fighting against oppression of landowners, money lenders anticipating that through these extremist Naxalites they will be able to find out their goal. But it is easy to break rather than to make. Killing people,damaging Government property nobody is going to gain anything. Tribals have realized today education is biggest strength of the society. With the back drop of tribal life BEYOND THE LINE is the story of struggle full life of tribals and keen desire to progress. Other stories will highlight various shades of human relations and mind set with blend of different tastes.

High energy laboratories are performing experiments in heavy ion collisions to explore the structure of matter at high temperature and density. This elementary book explains the basic ideas involved in the theoretical analysis of these experimental data. It first develops two topics needed for this purpose, namely hadron interactions and thermal field theory. Chiral perturbation theory is developed to describe hadron interactions and thermal field theory is formulated in the real-time method. In particular, spectral form of thermal propagators is derived for fields of arbitrary spin and used to calculate loop integrals. These developments are then applied to find quark condensate and hadron parameters in medium, including dilepton production. Finally, the non-equilibrium method of statistical field theory to calculate transport coefficients is reviewed. With technical details explained in the text and appendices, this book should be accessible to researchers as well as graduate students interested in thermal field theory.
