Abstract

A textbook that offers a unified treatment of the applications of hydrodynamics to marine problems.The applications of hydrodynamics to naval architecture and marine engineering expanded dramatically in the 1960s and 1970s. This classic textbook, originally published in 1977, filled the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures. It also serves as an introduction to more specialized research methods. It unifies the seemingly diverse problems of marine hydrodynamics by examining them not as separate problems but as related applications of the general field of hydrodynamics. The book evolved from a first-year graduate course in MIT's Department of Ocean Engineering. A knowledge of advanced calculus is assumed. Students will find a previous introductory course in fluid dynamics helpful, but the book presents the necessary fundamentals in a self-contained manner. The 40th anniversary of this pioneering book offers a foreword by John Grue.Contents Model Testing • The Motion of a Viscous Fluid • The Motion of an Ideal Fluid • Lifting Surfaces • Waves and Wave Effects • Hydrodynamics of Slender Bodies

Abstract

Carboxylic acids are truly central compounds in cellular metabolism. Carbon dioxide is captured from the atmosphere through formation of carboxylic groups and is also released, in part, by decarboxylation reactions. The reactivity of the carboxylic group with amino- or hydroxyl-groups enables the formation of peptide and ester bonds. The functionality of the carboxylic group is also of huge importance in our industrial world for a wide range of applications. The loosely bound hydrogen provides weak acid functionality, much desired for food industry applications in preservatives and flavour compounds. Citric acid is one of our oldest industrial fermentation products. The presence of two carboxylic groups, or a combination of one carboxylic group and another functional group, make the compounds interesting building blocks for polymer production. A number of carboxylic acids, including, e.g., lactic, succinic, 3-hydroxypropionic and itaconic acids, have been identified and recognized as suitable platform chemicals for a foreseen growing carbohydrate based economy. Economic margins are, however, tight when competing with petroleum based production, and production strains, fermentation technology and—not least—downstream processing, all need to be improved to enable viable commercial production.This Special issue will cover current developments within this exciting field. Topics will include: Fermentation physiology of natural carboxylic acid producers; screening and isolation of novel producers; metabolic engineering for improving intrinsic carboxylic acid production; metabolic engineering for expanding product range to non-endogenous carboxylic acids; production from lignocellulosic derived sugars or by-product streams; downstream processing for recovery of carboxylic acids; bioprocess design—including continuous processes and integration.All production organisms—fungi, yeasts, bacteria—are welcome.

Abstract

This special feature issue has been initiated to celebrate the 25th anniversary of Optical Coherence Tomography (OCT). In OCT, broad bandwidth light is used in order to produce cross sectional images of turbid and translucent samples with high axial resolution (in the order of a few µm). The imaging speed of OCT can be as high as several millions of depth scans (A-scans) per second which allows for various applications in different fields. This special feature issue consists of three overview papers covering OCT angiography, polarization-sensitive OCT and dental applications of OCT. Additional applications and the latest developments in OCT are covered in nine research papers. The latest developments presented in this issue include magnetomotive OCT, resonant Doppler OCT, full field OCT, new segmentation algorithms and depth range extension. Applications of OCT are widely spread and range from quality control in tooth prostheses and coating thickness measurements in the automotive industry to the assessment of degradation of coatings and alveolar dynamics.

Abstract

Catechols are widely found in nature taking part in a variety of biological functions, ranging from the aqueous adhesion of marine organisms to the storage of transition metal ions. Catechol-based natural and biomimetic molecules have thus been the focus of intense research aimed at mimicking and translating this nature-inspired chemistry into new functional materials and systems with tailored properties. The aim of this book is to present a concise survey of the state-of-the-art of basic and applied research on bioinspired catechol systems. It collects several cutting-edge contributions from leading laboratories with a unifying theme of biomimetic principles and approaches. It is hoped that both practitioners and newcomers to the field will by fascinated by the unique potential of biomimetics to pursue new research and innovative solutions in biomedicine and technology.

Abstract

Since Langer’s seminal work, polymers have been on every corner of tissue engineering. The roles of bioresorbable polymers, as a scaffold, are not merely structural, providing three-dimensional (3D) homing sites to cells, but also functional at their interface with the cells. The polymeric scaffolds actively act as both biochemical and physical cues for cell behaviors, such as adhesion, growth, proliferation, and differentiation. Polymers and cells could interact further with each other mutually, sensing and responding to the signals from the partner. Technological advances in this direction, including chemical modification of polymer scaffolds, highly cytocompatible hybrid materials/composites, dynamic scaffolds, control of juxtacrine interactions, and 3D bioprinting and microfluidic devices, ensure the advances in polymers as cell scaffolds. The detection and characterization methods for cell-material interactions and cell behaviors have been greatly improved, and new characterization techniques have emerged. Recent years have witnessed a quantum leap of progress in tissue engineering and regenerative medicine, and this edited book illustrates some of the advances in polymers as cell scaffolds.

Abstract

This volume features thirteen original chapters on the causes and consequences of gender segregation in scientific, technical, engineering, and mathematics (“STEM”) occupations and fields of study. Although women have made great strides in equalizing access to labor markets and higher education, many STEM fields—particularly in the physical sciences and engineering—remain strongholds of gender segregation in the United States and other reputably gender-progressive societies. Policymakers, business leaders and activists have launched countless initiatives to diversify access to lucrative, high status occupations and ameliorate labor shortages that diminish innovation and competitiveness.Contributors to this volume apply diverse theoretical lenses and methodological approaches to understand the individual, interactional, organizational, and cultural dynamics that drive this segregation in the United States. Results show that the gender composition of scientific and technical fields varies a great deal over time and across organizational contexts and socio-demographic groups defined by race, ethnicity, class, and sexuality. But despite this variability, STEM work and STEM workers are widely presumed to be naturally and inevitably masculine. Research presented here reveals how these stereotypes combine with cultural beliefs about natural and fundamental differences between men and women to produce gendered aspirations and reinforce inequalities in the US scientific and technical workforce.

Abstract

Hydrogels are the foundation of regenerative medicine as a supportive matrix for cell immobilization and growth factor delivery. The fate of implanted cells is mediated by cell-matrix interaction at multiple scales and timed-release of growth factors to guide the differentiation and maturation of cells. Recently, there has been great interest in hydrogels with a hierarchical structure that mimics the complex interaction of cells with a microenvironment that can locally release growth factors to specific cells. Related topics in this Special Issue include hydrogels with a hierarchical structure; hybrid, degradable, and load-bearing hydrogels; hydrogels for cell encapsulation, micro-patterning, microfluidic devices, biofabrication, and high-throughput screening; and hydrogels that modulate the body’s immune response.
