    Ultrasound has a wide range of medical applications. Some of these include obstetrics (monitoring the progress of pregnancy), oncology (monitoring the growth of tumors), cardiology (visualizing the heart function and physiology), biopsy (guiding needles in various procedures), and physiotherapy. For example, today, an estimated 60-70% of pregnant women in the United States undergo ultrasound examination during pregnancy. An estimated 250 million fetal ultrasound examinations are performed every year in the USA. In the last few decades, ultrasound technology has expanded to medical imaging in various other specialties: Anesthesiology, Critical Care, Emergency Medicine, General Pediatrics, Internal Medicine, Obstetrics and Gynecology (OB-GYN), Pediatric Emergency Medicine, Physiatry, Sports Medicine, and Surgery. The increasing demand in the use of ultrasound technology in various biomedical fields points to a future in which medical professionals will be required to possess a general knowledge of ultrasound technology. While currently most medical professionals rely on technicians to perform the imaging studies, there can be a high degree of operator dependent results. Therefore, a solid foundation of the technological properties of ultrasound would give health care providers a competitive advantage in the future. This is one of the first goals of this textbook. This textbook also covers general aspects of diagnostic ultrasound providing an excellent reference for both beginners and professionals. In addition, this textbook has end-of-the-chapter experiments that will help educators conduct labs for students and any other learners to enhance their learning and solidify the practical skills.

    Electrolysers, Fuel Cells and Batteries: Analytical Modelling

    Copyright Year:

    Electrochemical engineering deals with electrochemical devices like electrolysers, fuel cells, and batteries. While several excellent books exist in this long-standing and still growing field, their focus is usually on chemistry or phenomenology. In this textbook, we focus on mathematical modelling of the physical phenomena involved. Instead of resorting to numerical modelling, the aim is to derive simplified analytical models that maximise understanding. Porous electrodes, ion mass transport, and multiphase flow are central themes in this book. Examples include modelling the water saturation in a fuel cell diffusion layer, the gas fraction and current distribution in an alkaline water electrolyser, the potential distribution in a binary electrolyte inside porous battery electrode, and the concentration distribution in the flow channel of a redox flow battery. This makes for a diverse, challenging, and stimulating journey, for both students and researchers.

    This open access textbook focuses on the various aspects of radiobiology. The goal of radiobiological research is to better understand the effects of radiation exposure at the cellular and molecular levels in order to determine the impact on health. This book offers a unique perspective, by covering not only radiation biology but also radiation physics, radiation oncology, radiotherapy, radiochemistry, radiopharmacy, nuclear medicine, space radiation biology & physics, environmental and human radiation protection, nuclear emergency planning, molecular biology and bioinformatics, as well as the ethical, legal and social considerations related to radiobiology. This range of disciplines contributes to making radiobiology a broad and rather complex topic. This textbook is intended to provide a solid foundation to those interested in the basics and practice of radiobiological science. It is a learning resource, meeting the needs of students, scientists and medical staff with an interest in this rapidly evolving discipline, as well as a teaching tool, with accompanying teaching material to help educators.

    Se examina estrategias para optimizar la alimentación de rumiantes mediante el cultivo y manejo de diferentes forrajes en Santo Domingo de los Tsáchilas, Ecuador. En el primer capítulo, se destaca cómo el encalado y la fertilización mejoran el rendimiento del maíz, enfatizando en dosis óptimas de nutrientes. El segundo capítulo aborda la fertilización orgánica del pasto Mombasa bajo sombra de naranja, resaltando la superioridad de la pollinaza en el incremento de rendimiento y calidad del forraje. Los capítulos siguientes se centran en la edad óptima de corte para maximizar la biomasa del pasto Cuba OM-22, el manejo del King Grass como alternativa forrajera para el sector ganadero, y el desarrollo del forraje verde hidropónico de sorgo y maíz a dos densidades de siembra, demostrando que técnicas específicas de manejo y cultivo pueden significativamente influir en la productividad y sostenibilidad de la alimentación rumiante. A través de estos estudios, el libro propone soluciones prácticas y sustentables para mejorar la nutrición de rumiantes en entornos tropicales.

    Se establecen los principios bioquímicos fundamentales que rigen el desarrollo de las plantas, explorando la composición y estructura de sus células. Además, se aborda la fotosíntesis como un proceso metabólico esencial. El metabolismo de biomoléculas, que incluye el transporte de nutrientes y la síntesis de carbohidratos, lípidos, proteínas y otros compuestos, es analizado en profundidad. Asimismo, se abordan temáticas cruciales como la respiración celular en plantas, la biosíntesis de metabolitos secundarios y el papel de las hormonas vegetales en el crecimiento y desarrollo. La enzimología vegetal, con énfasis en la cinética enzimática, se presenta como un componente esencial del metabolismo vegetal. Además, se examinan los mecanismos de defensa de las plantas frente al estrés abiótico y biótico, abordando la morfogénesis y los desafíos que enfrentan las plantas en su entorno. El libro concluye con una visión hacia el futuro en la investigación de la bioquímica vegetal.

    This book focuses on three important elements in the development of cereal and legume crops in semi-arid West Africa. The first section illustrates the socioeconomic factors that affect the food system for these crops and contains an overview of crop production and consumption in the region. Then, important inputs that affect system productivity are presented: preferences for new seed varieties, yield response to fertilizer, counterfeit herbicides, climate information, and the way farmers develop expectations about the weather events that shape cropping outcomes. The final chapter of section one is dedicated to understanding urban consumer preferences for processed food products derived from pearl millet.
