ABSTRACT -— The interactions of hadrons are described from the point of view of quarks. Weak, electromagnetic and strong coupling constants are evaluated with a relativistic quark model using the BETHE-SALPETER formalism. Uniquely defined S U (3) mass breaking factors are derived from the quark dynamics inside the mesons. 

ABSTRACT — The present work begins with a survey of ferromagnetic anysotropies and discusses the methods used in their experimental determination.
