The 14th International Symposium on Superalloys (Superalloys 2020) highlights technologies for lifecycle improvement of superalloys. In addition to the traditional focus areas of alloy development, processing, mechanical behavior, coatings, and environmental effects, this volume includes contributions from academia, supply chain, and product-user members of the superalloy community that highlight technologies that contribute to improving manufacturability, affordability, life prediction, and performance of superalloys.

Mastering Numbers is a comprehensive coverage of techniques that enable a person of any age to solve numeracy problems without the use of a calculator. It addresses simplified strategies that enable a person to solve numeracy calculations for all four operations significantly faster than traditional methods. In exploring techniques to solve the single digit multiplication, Mastering Numbers does not rely on a ROTE learning approach but explains the basic patterns that underlie any single digit multiplication. Using the Vedic pattern of multiplication and the system of mental calculation devised by Professor Jakow Trachtenberg, it demonstrates with a step by step process the numerous shortcuts to solve 2 digit by 2 digit multiplications very very quickly. Mastering numbers also explores the 3 digit by 3 digit multiplications that with practice can be solved faster than using a calculator. Dividing any number by 2 digit or 3 digits uses the reverse process of Trachtenberg's multiplication system, where you only divide a number by the first digit of the divisor. Because a book by its very nature is a static learning device, there are both PowerPoints that explain each example in the book and self-correcting worksheets to help master the skills and concepts. These are available by contacting the author at the following website modmaths.com.au Any one (even those who are young at heart) working through the skills of this book, will hopefully become more confident in their approach to Maths. By learning the patterns and techniques, that enable you to solve problems quickly, you may overcome any fear of Maths, enjoy the challenge of solving Maths problems and maybe discover a sense of empowerment that comes with "playing" with numbers.

I grew up in the city of Springfield, MA with thousands of people around you coming and going as you walk along the street of the city. It's hard to stop one person and speak life into them, so I thought. As I went through life as a teenager I always wanted to be the one person to help out and give the best advice as possible. Everyone always said I gave great advice, so my goal was to reach out and speak a word of encouragement to just one person a day. Although, I never had the confidence or courage to give a simple "hello, how are you" to just any random person. Then, it all changed. I came to Christ in December of 2012. God has transformed my life around for the better. God gave me the courage to speak life into people every day. It is no longer a challenge to spread the good news because now I have an understanding that spreading the Gospel is what we are called to do. My prayer is that this book helps uplift you every day and to water that seed of hope inside of you.

This collection features five peer-reviewed reviews on optimising rootstock health. The first chapter explores optimising rootstock health to improve root function, resource-use efficiency, sustainability and agricultural productivity. The chapter also presents a case study on tomato rootstocks as a viable strategy to overcome abiotic stresses in Ghana. The second chapter reviews the important aspects of tree growth and development in apple production which are integral to ensure product quality. The chapter discusses the importance of rootstocks and emphasises the mechanisms and morphological effects of dwarfing on rootstocks. The third chapter considers recent advances in the development and utilisation of fruit tree rootstocks, focussing primarily on apples. The chapter also reviews rootstock tolerance to both abiotic and biotic stresses. The fourth chapter discusses advances in avocado tissue culture for clonal propagation and highlights the potential of this technology for improving the sustainable supply of high-quality avocado plants to support future avocado industry growth. The final chapter addresses the challenges and opportunities in pear breeding, focussing on pear cultivars, pear rootstocks and germplasm resources. The chapter also considers the use of dwarfing as a means of improving particular traits.
