UFC 285 is one of the events of the Ultimate Fighting Championship that took place on May 30, 2020. It was scheduled to take place in Astana Arena, but due to the COVID-19 pandemic, it was moved to the UFC Apex facility in Las Vegas, Nevada. The main event of UFC 285 was a welterweight bout between former champion Tyron Woodley and Gilbert Burns. Woodley, who held the title for three years, was looking to reclaim it after losing it to Kamaru Usman in 2019. Burns, on the other hand, was on a five-fight winning streak and looking to make a statement in his first main event in the UFC. Apart from the main event, UFC 285 also featured an exciting co-main event between female flyweights Katlyn Chookagian and Antonina Shevchenko. Chookagian was coming off a loss to Valentina Shevchenko, Antonina's sister, while Antonina had won her last two fights. This bout was significant as it could potentially lead to a match between Chookagian and Valentina Shevchenko for the flyweight championship. UFC 285 also had a heavyweight bout between Blagoy Ivanov and Augusto Sakai, a female strawweight bout between Mackenzie Dern and Hannah Cifers, and a bantamweight bout between Eddie Wineland and Sean O'Malley. With these exciting matches and talented fighters, UFC 285 promised to be a memorable event for MMA fans.

An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.

Mixed Martial Arts outlines the revolutionary system of fighting used by world-renowned fighter BJ Penn. Penn, one of the most technical and decorated fighters in the world today, illustrates fighting techniques that teach you how to mix strikes with takedowns, ground and pound an opponent into submission, fight against the cage and formulate strategies based upon your personal attributes and strengths.

As the demand for efficient energy sources continues to grow around the globe, electrical systems are becoming more essential to meet these increased needs. As these systems are being utilized more frequently, it becomes imperative to find ways of optimizing their overall function. Design Parameters of Electrical Network Grounding Systems is a critical scholarly resource that examines safe grounding designs of electrical networks. Featuring coverage on a broad range of topics such as cathodic protection of grounding grids, grounding connections, and soil resistivity evaluation, this book is geared towards academicians, practitioners, and researchers seeking current research on electrical networks.

With the very first UFC, the new sport of mixed martial arts (MMA) was launched-although it wasn't even called that yet-and fighting would never again be the same. Now, for the first time, the true story of how the Ultimate Fighting Championship came into existence is told by the man who started it all. In this vivid and fast-moving, first-person account, Davie explains how his idea to crown the World's Best Fighter painstakingly evolved into the UFC, which now stands as a billion-dollar sports franchise.
