The Delft Sand, Clay & Rock Cutting Model
Sape Miedema · TU Delft Open · 2019
In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

Bending the Curve: Climate Change Solutions
Veerabhadran Ramanathan; Roger Aines; Max Auffhammer · eScholarship · 2019
Climate change is an urgent problem. Because it is causing new weather extremes and fatal catastrophes, climate change is better termed climate disruption. Bending the curve to flatten the upward trajectory of pollution emissions responsible for climate disruption is essential in order to protect billions of people from this global threat. Education is a key part of the solution. This textbook book lays out ten solutions that together can bend the curve of climate warming below dangerous levels. These solutions fall into six categories: science, societal transformation, governance, economics, technology, and ecosystem management. Four themes emerge from the book: * There is still time to bend the curve. The time to act was yesterday, but if proper actions are taken now, there is still time to avoid disastrous changes. We have to pull on three levers: The carbon lever to achieve zero net emissions of carbon dioxide before 2050; the short-lived climate pollutants lever to drastically reduce concentrations of other major climate pollutants; and the atmospheric carbon extraction lever to remove massive amounts of carbon dioxide from the atmosphere. * Bending the curve will require interdisciplinary solutions. Climate change requires integrating approaches from the natural sciences, social sciences, and humanities, so this textbook—unlike most on climate change solutions—does just that, with chapters written by experts in climate science, social justice, economics, environmental policy, political science, energy technologies, ecology, and religion. Bending the curve also requires preservation and restoration of ecological systems. * Bending the curve requires a radical shift in attitude. This shift requires change in behavior, change in our attitudes towards each other, and change in our attitude towards nature. Climate justice has to be an integral part of the solution. * Technology, market mechanism and policy need to be a part of the solution. New market mechanisms an

Virology Lab Exercises for Undergraduates
Eric Ryndock · The Pennsylvania Alliance for Design of Open Textbooks (PA-ADOPT) · 2026
This laboratory manual presents a novel series of undergraduate-friendly experiments designed to provide students with a safe, accessible, and comprehensive introduction to virology. The manual is intended for students who already possess foundational knowledge in cell biology, genetics, and molecular biology, and it emphasizes hands-on learning through diverse experimental approaches. Unlike many existing virology laboratory manuals that depend on costly infrastructure such as mammalian cell culture facilities or focus narrowly on a single viral system, this manual was developed specifically for primary undergraduate teaching institutions. The experiments utilize readily available equipment while exposing students to representative viruses that infect bacteria, plants, and animals. Through these investigations, students gain practical experience with modern virological techniques and develop transferable, employable skills relevant to biotechnology, research, and related industries. Collectively, the laboratory exercises aim to strengthen conceptual understanding of viral biology, promote technical competency, and inspire student curiosity about viruses as dynamic and influential biological entities.

Biotechnology Foundations
Jack O'Grady · OpenStax CNX · 2013
Given the broad definition of biotechnology applications and products, it is easy to see how there is enormous overlap within the fields of cellular biology, microbiology, chemistry, and biomedical engineering. It is the goal of this textbook to provide foundational knowledge to begin building your biotechnology toolkit and enter an exciting career of making a difference through biotechnology. This textbook first explores the fundamentals of laboratory science and biotechnology. Unit 1 begins with a dive into the foundation of biology and chemistry by asking what is life and what are the molecules of life? The end of the unit offers a primer into laboratory science; preparing solutions and operating basic lab equipment. Unit 2 brings readers through a vital tool of biomanufacturing, understanding the growth and control of microbes. Many biotechnology products are made by harnessing the work of microbes, and this unit explores this invisible and intriguing world of microorganisms. The final unit, molecular biotechnology, offers a more in-depth look at how biological molecules such as DNA and protein are manipulated into creating useful products.

Threshold Concepts in Biochemistry
Julian Pakay; Hendrika Duivenvoorden; Thomas Shafee; Kaitlin Clarke · La Trobe University · 2023
Biochemistry (and Molecular Biology) represent one of the fastest-growing fields of scientific research and technical innovation and the resulting biotechnology is increasingly applied to other fields of study. So, an understanding of Biochemistry is increasingly important for students in all biological disciplines. However, at the same time, the content is inherently complex, highly abstract, and often deeply rooted in the pure sciences – mathematics, chemistry, and physics. This makes it difficult to both learn and to teach. This book is designed as a succinct and focused resource, specifically aimed to help students grasp key threshold concepts in Biochemistry. Due to their troublesome nature, understanding threshold concepts is a cognitively demanding task. By using a series of thematically linked case studies that accompany theory, the cognitive load will be reduced. This will free up students to focus on learning concepts rather than distracting them with unnecessary specifics.

Future Energy: Opportunities & Challenges
Thomas Kerlin · The University of Tennessee Libraries · 2013
How can we produce enough sustainable energy while avoiding unacceptable environmental consequences? To evaluate the various energy options, we must understand the science of each potential energy source and energy use technology. This book presents the science in an easy-to-understand way to enable readers to make informed decisions about what is possible and practical, and to choose lifestyle options to implement in their personal lives. America and the world face daunting questions about how we produce energy and how we use it. Conservation and improved energy efficiency can help reduce energy requirements, but cannot halt the steady increase in energy consumption. An increasing world population and increasing energy appetites in emerging economies will create competition for energy resources for all nations. The possibilities for future energy production include fossil fuels (oil, natural gas, coal, oil sands, and oil shale), biofuels, solar, wind, hydro-energy, geothermal, and nuclear (probably fission and possibly fusion). Each of these sources has relative advantages and disadvantages. The problem is to produce enough sustainable energy while avoiding unacceptable environmental consequences, especially climate change. In order to evaluate the potential of the various energy options, one must understand the basic science that underlies each potential energy source and energy use technology. This knowledge will enable us to determine what is possible and practical and, maybe more importantly, what is impossible or impractical. Fortunately most of the pertinent science is old, well established and, for the most part, quite simple. This science provides a framework into which one can insert real data and draw conclusions. Without such quantitative assessments, claims about capabilities of the various energy options must be viewed as unverified assumptions rather than hard facts. This book presents the essential science in an easy-to-understand, yet comprehensive
