Ellingson is a 238-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current. Additional ResourcesProblem sets and the corresponding solution manual are also available.4992018-09-07T17:22:06Z2024-03-25T13:06:55ZLaboratory Exercises in Microbiology: Discovering the Unseen World Through Hands-On Investigation<img alt="Read more about Laboratory Exercises in Microbiology: Discovering the Unseen World Through Hands-On Investigation" title="Laboratory Exercises in Microbiology: Discovering the Unseen World Through Hands-On Investigation cover image" class="cover " width="1075" height="1356" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NDI3LCJwdXIiOiJibG9iX2lkIn19--8d29e7b755ee5479c8a38099937cc71347d8778d/0000LabExeMic.png" />The exercises in this laboratory manual are designed to engage students in hand-on activities that reinforce their understanding of the microbial world. Topics covered include: staining and microscopy, metabolic testing, physical and chemical control of microorganisms, and immunology. The target audience is primarily students preparing for a career in the health sciences, however many of the topics would be appropriate for a general microbiology course as well.5062018-09-07T17:22:06Z2024-01-22T14:52:23ZLaboratory Manual for Introductory Geology<img alt="Read more about Laboratory Manual for Introductory Geology" title="Laboratory Manual for Introductory Geology cover image" class="cover " width="815" height="1055" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NDMzLCJwdXIiOiJibG9iX2lkIn19--c2ea9b1b4c97d508fefda4ad055d32fa4b45615a/9781940771366.png" />This textbook is a comprehensive lab manual for the core curriculum Introductory Geosciences classes with both informational content and laboratory exercises.

There are countless cooking books, TV shows, celebrity chefs and kitchen gadgets that make cooking an enjoyable activity for everyone. The chemistry of cooking course seeks to understand the science behind our most popular meals by studying the behavior of atoms and molecules present in food. This book is intended to give students a basic understanding of the chemistry involved in cooking such as caramelization, Maillard reaction, acid-base reactions, catalysis, and fermentation. Students will be able to use chemistry language to describe the process of cooking, apply chemistry knowledge to solve questions related to food, and ultimately create their own recipes.4862018-09-07T17:22:05Z2024-03-11T13:06:27ZAnalytical Chemistry 2.1<img alt="Read more about Analytical Chemistry 2.1" title="Analytical Chemistry 2.1 cover image" class="cover " width="1014" height="1282" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NDE0LCJwdXIiOiJibG9iX2lkIn19--1be4e5cc644de5e61a6c944d4f94c594f28b5c92/0000AnaChem.png" />As currently taught in the United States, introductory courses in analytical chemistry emphasize quantitative (and sometimes qualitative) methods of analysis along with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is much more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. Although equilibrium chemistry and analytical methods are important, their coverage should not come at the expense of other equally important topics. The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum for exploring topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results. Analytical methods come and go, but best practices for designing and validating analytical methods are universal. Because chemistry is an experimental science it is essential that all chemistry students understand the importance of making good measurements. My goal in preparing this textbook is to find a more appropriate balance between theory and practice, between “classical” and “modern” analytical methods, between analyzing samples and collecting samples and preparing them for analysis, and between analytical methods and data analysis. There is more material here than anyone can cover in one semester; it is my hope that the diversity of topics will meet the needs of different instructors, while, perhaps, suggesting some new topics to cover.4902018-09-07T17:22:05Z2024-01-22T14:52:01ZVariational Principles in Classical Mechanics - Revised Second Edition<img alt="Read more about Variational Principles in Classical Mechanics - Revised Second Edition" title="Variational Principles in Classical Mechanics - Revised Second Edition cover image" class="cover " width="610" height="774" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6MTk4NCwicHVyIjoiYmxvYl9pZCJ9fQ==--b83bd0d993868fcd3606c6ab741cb315456811e5/v%E1%BA%A3iehfbhd.JPG" />Two dramatically different philosophical approaches to classical mechanics were proposed during the 17th – 18th centuries. Newton developed his vectorial formulation that uses time-dependent differential equations of motion to relate vector observables like force and rate of change of momentum. Euler, Lagrange, Hamilton, and Jacobi, developed powerful alternative variational formulations based on the assumption that nature follows the principle of least action. These variational formulations now play a pivotal role in science and engineering. This book introduces variational principles and their application to classical mechanics. The relative merits of the intuitive Newtonian vectorial formulation, and the more powerful variational formulations are compared. Applications to a wide variety of topics illustrate the intellectual beauty, remarkable power, and broad scope provided by use of variational principles in physics. This second edition adds discussion of the use of variational principles applied to the following topics: Systems subject to initial boundary conditions The hierarchy of the related formulations based on action, Lagrangian, Hamiltonian, and equations of motion, to systems that involve symmetries Non-conservative systems. Variable-mass systems. The General Theory of Relativity.

It is an ethically based whole-systems design approach that uses concepts, principles, and methods derived from ecosystems, indigenous technologies, and other time-tested practices to create sustainable human settlements and institutions. Although rooted in horticulture and agriculture, Permaculture design is interdisciplinary, touching on a wide range of subjects including regional planning, ecology, animal husbandry, appropriate technology, architecture, social justice, and international development. This open text book is derived from the content of the Massive Open Online Course “Intro to Permaculture”. The original course also included interactive mapping and design tools that accompanied this content. The course and book provide a general overview of the Permaculture design system. The book can be downloaded as a print version. However, there are many accompanying videos and content pages that are linked to throughout the text, so it is best viewed online where the links can be accessed.4702018-09-07T17:22:04Z2024-01-22T14:52:19ZMicrobiology<img alt="Read more about Microbiology" title="Microbiology cover image" class="cover " width="625" height="475" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6Mzk4LCJwdXIiOiJibG9iX2lkIn19--6120bd6d4250c6a8b91d610e8f5427ae20f3fdc3/0000Microbiol.png" />In this textbook the focus will be on the bacteria and archaea (traditionally known as the “prokaryotes,”) and the viruses and other acellular agents.4722018-09-07T17:22:04Z2024-01-22T14:51:56ZOrganic Chemistry with a Biological Emphasis Volume I<img alt="Read more about Organic Chemistry with a Biological Emphasis Volume I" title="Organic Chemistry with a Biological Emphasis Volume I cover image" class="cover " width="1020" height="1453" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NDAwLCJwdXIiOiJibG9iX2lkIn19--eb5a3e584e033e7958bf8c2d207085bfa8220698/0000OrgCheWit.png" />The traditional approach to teaching Organic Chemistry, taken by most of the textbooks that are currently available, is to focus primarily on the reactions of laboratory synthesis, with much less discussion - in the central chapters, at least - of biological molecules and reactions. This is despite the fact that, in many classrooms, a majority of students are majoring in Biology or Health Sciences rather than in Chemistry, and are presumably taking the course in order to learn about the chemistry that takes place in living things.In an effort to address this disconnect, I have developed a textbook for a two-semester, sophomore-level course in Organic Chemistry in which biological chemistry takes center stage. For the most part, the text covers the core concepts of organic structure, structure determination, and reactivity in the standard order. What is different is the context: biological chemistry is fully integrated into the explanation of central principles, and as much as possible the in-chapter and end-of-chapter problems are taken from the biochemical literature. Many laboratory synthesis reactions are also covered, generally in parallel with their biochemical counterparts - but it is intentionally the biological chemistry that comes first.4732018-09-07T17:22:04Z2024-01-22T14:51:56ZOrganic Chemistry with a Biological Emphasis Volume II<img alt="Read more about Organic Chemistry with a Biological Emphasis Volume II" title="Organic Chemistry with a Biological Emphasis Volume II cover image" class="cover " width="999" height="1298" data-controller="common--cover" data-placeholder="/assets/common/placeholder-0e0607cbc50663ddb9e8fd188058bcd2630c730ef6ee322801278607b7d5af8e.png" src="/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsiZGF0YSI6NDAxLCJwdXIiOiJibG9iX2lkIn19--e954e005e4ee9a1c3c73eecc51322f5718a4cd10/0000OrgCheWi2.png" />The traditional approach to teaching Organic Chemistry, taken by most of the textbooks that are currently available, is to focus primarily on the reactions of laboratory synthesis, with much less discussion - in the central chapters, at least - of biological molecules and reactions.
