This book reviews drug delivery systems as mechanisms to introduce therapeutic agents into the body to help or improve tissue function, and examines different drug delivery systems applied in various organs. To date, polymeric systems, ceramic particles or composites have been used in different applications such as injectable, coatings of implants, scaffolds, or implantable devices. Such systems should be able to retain the therapeutic agent and release it in uniform amounts at a specific time.
This book provides an overview of the composition of polymeric and ceramic bone cements. It also discusses complex, biomimetic structures based on biomaterials, such as cells and bioactive molecules, which more closely resemble natural bone The first chapter describes the main concepts of the cementation process and the parameters affecting it, while the second chapter focuses on the composition and structure of candidate biomaterials. Lastly, the third and fourth chapters present recent research aimed at improving the ability of naked biomaterials to enhance bone healing by adding cells and bioactive agents.
صبح هشتم ژانویه ۲۰۲۰ هواپیمای مسافربری اوکراین پرواز 752 آسمان تهران با شلیک دو موشک منفجر شد. کلیه مسافران این هواپیما در آتش بلاهت و جباریت سوختند. تنها بازمانده این هواپیما خرگوشی بود به نام راشل که غروب روز قبل از پرواز، بلیتش از طرف شرکت هواپیمایی کنسل شده بود. ده ماه بعد از این حادثه هولناک بازماندگان برخی از این گل نثاران، به سراغ من آمدند تا خاطراتشان را بنویسند. این کتاب داستان خاطرههاست. خاطرههای نوشته شده و گفته شده، خاطره آنچه در کلاس اتفاق افتاد. گریهها، حسرتها، خندهها و شادیها... شما در این کتاب شیوه رهیابی و کوچینگ یک مدرس خاطرهنویسی را میبینید.

Bioceramics have been used very successfully within the human body for many years. They are commonly used in orthopaedic surgery and dentistry but they are potentially suitable for a wide range of important applications within the medical device industry. This important book reviews the range of bioceramics, their properties and range of clinical uses.Chapters in the first section of the book discusses issues of significance to a range of bioceramics such as their structure, mechanical properties and biological interactions. The second part reviews the fabrication, microstructure and properties of specific bioceramics and glasses, concentrating on the most promising materials. These include ...
This book highlights both theoretical and applied advances in cellular learning automata (CLA), a type of hybrid computational model that has been successfully employed in various areas to solve complex problems and to model, learn, or simulate complicated patterns of behavior. Owing to CLA’s parallel and learning abilities, it has proven to be quite effective in uncertain, time-varying, decentralized, and distributed environments. The book begins with a brief introduction to various CLA models, before focusing on recently developed CLA variants. In turn, the research areas related to CLA are addressed as bibliometric network analysis perspectives. The next part of the book presents CLA-based solutions to several computer science problems in e.g. static optimization, dynamic optimization, wireless networks, mesh networks, and cloud computing. Given its scope, the book is well suited for all researchers in the fields of artificial intelligence and reinforcement learning.
This book introduces the origins of important teachings that form the basis of medicine and related healing professions. Reinforcing the humanistic side of patient care, this book replicates the tips, anecdotes and aphorisms often related by mentors and educators to medical students, residents, and young physicians. This book provides numerous examples of best practices in the art of medicine, profiles of great healers throughout history and around the world, and stories sure to inspire any practicing healer, whether they are new to the calling or a seasoned veteran.
