One of the most successful, fascinating and useful applications of mathematics has been in the study of motions of fluids (gases and liquids).The perfect or ideal fluids are characterized by the assumptions that for then the stress tensor is a linear function of the rate of strain tensor and the stress vector on a plane surface in contact with a fluid is normal to the surface. About seven decades ago phenomena were observed which could not be explained on the assumptions of this theory. When the assumptions of this theory were examined, it was considered feasible to relax the assumption of...

Veterinary Entomology and Acarology provides a systematic comprehension of the arthropods of veterinary importance. It covers detailed morphology, life cycle, pathogenesis, clinical picture, diagnosis, treatment, management and control of arthropods related to animals. Authors made an effort to simplify the complexity of veterinary entomology and acarology by incorporating the most important details about arthropods in bullet points. The book includes labelled line diagrams of arthropods showing important morphological identification characters. The authors tried to tackle the topics...
