Polymer Stress Reactions, Volume 1: Introduction focuses on the interrelationship between polymer mechanochemistry and the stress-induced polymer reactions. This book discusses each nominal polymer state and describes the parameters and variables that are germane to the mechanically induced reactions in that state. The polymer degradation variables that are generally applicable to mechanochemistry, such as temperature and shear intensity, are also considered. This book consists of five chapters and begins with an overview of mechanochemistry and stress-induced polymer reactions, with particular reference to the distinction between mechanochemical reactions and other modes of reaction. The general regions of viscoelastic behavior for amorphous polymers where mechanochemistry may be conducted are also described. The next chapter explores the mechanisms underlying the modes of reaction in mechanochemistry, focusing on the effects of shear and applied stress as well as how bonds rupture. The discussion then turns to the influence of the principal variables in polymer mechanochemistry; characterization methods for evaluating the fundamentals of mechanochemistry; and methods for the synthesis of block and graft copolymers. This book is a valuable material for those interested in mechanochemistry in general and in polymer stress reactions in particular.

We think we are indestructible. We pretend of being in full control of our destiny and become arrogant and unapproachable on a human level. Man is only a component in the vast scenario of universal existence. The human race breeds in a constant conflict of manipulations, distortions, Machiavellian schemes and Sisyphean delusions. When he learns to bend his knee in a state of humility, he begins to grow.

Polymer Stress Reactions, Volume 2: Experiments provides an overall world perspective for the field of polymer reactions caused by stress. For the reader''s benefit the book is developed along several lines for ease of reference. The same studies may thus be discussed from different points of view such as type of equipment, polymer used, basic parameters, and the polymer state. Presentation by polymer state is a fundamental, i.e., a molecular approach to mechanochemistry. The discussion of each nominal polymer state includes a description of those parameters and variables which are germane to the mechanically induced reactions in that state. In contrast, the variables which are generally applicable to mechanochemistry, such as temperature and shear intensity, are subsequently treated individually. The present volume contains two main chapters. The first reviews the principal experiments on each of the most researched polymers, both natural and synthetic; the second discusses studies of the polymer state in mechanochemistry.

For some...love...is a simple formality, a transition from sweet romanticism to nuptial responsibility; for others, it becomes an endless, tempestuous enigma where microscopic components play a crucial role on the unpredictable scenario of human stage. Love was and is a mystery. Those who pretend holding the key that unravels its meanders, are perhaps, dreamers in the inscrutable, cosmic vortex of human feelings.

Luigi was an avid writer on the Italian Facebook. A reader, Emily, acknowledged with satisfaction one of his messages and he began an online conversation with her that lasted three months. Emily was thirty- eight years old and Luigi seventy-nine. The age difference did not bother her. Her objective was another. Prior to the pandemic of 2019, Emily tried her luck in a restaurant business with a young man. When the virus appeared, the two lost their business and relation. Emily searched for a job in a company whose owner operated a young girls prostitution ring. Emily attended the interview, but it was late when she realized of the nature of the business. The boss locked her up in a bedroom ready to dispatch her to the Virgin Island. Due to a breaking in the piping system. Luigi joined his brother-in-law, a master plumber to the premises. Luigi heard cries and unlocked the prison door. He hid Emily in a big box and brought it to safety. The two never met and she vowed to meet some day her savior. Luigi and Emily began to socialize on online unaware of their past meeting. The conversation soon assumed romantic tones and Emily promised to visit him in Syracuse. That event never materialized.
