Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.
At its core, the LEGO MINDSTORMS(TM) NXT product provides a programmable microprocessor. Students use the NXT processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying geometry of the experimental model, as well as the geometric definition of the constant π (pi), students form an empirical ratio of areas to estimate a numerical value of π. Although typically used for numerical integration of irregular shapes, in this activity, students use a Monte Carlo simulation to estimate a common but rather complex analytical form the numerical value of the most famous irrational number, π.
This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large trains. There is then a demonstration in which a loop "jumps" because of a changing magnetic field. Finally, formal lecture reviews the cross product with respect to magnetic force and introduces magnetic flux, Faraday's law of Induction, Lenz's Law, Eddy currents, motional EMF and Induced EMF.

This book is a supplement to the online lectures and learning exercises in Introduction to Cheese Technology, a short course by the Department of Food Science, University of Guelph. However, please note that, in addition to the manual, you will need to refer to other materials throughout the course. The manual is also freely available to anyone online. You may use the content for personal reference and educational purposes provided you include a citation with the appropriate URL as follows: [Hill and Ferrer, Cheese Making Technology e-Book, accessed 27 Oct 2020].We would also like to extend an invitation to any readers who may be interested in learning more about cheese technology. Please check out the online Cheese Making Certificate and associated courses at this link. If you do not wish to complete the entire certificate, you can still enroll in any of the courses.
Chemical Engineering Separations: A Handbook for Students is intended for use by undergraduate students who are taking a course in chemical engineering separations. The handbook assumes that students have taken one or two semesters of chemical engineering thermodynamics, one semester of heat and mass transfer, and one semester of computational methods for chemical engineering.
Chemistry is the scientific study of matter and its interaction with other matter and with energy. It is the branch of natural science that deals with the composition of substances and their properties and reactions.
Student groups are given captioned photographs of the Chernobyl Nuclear Power Plant facility and surrounding towns taken before and 28 years after the 1986 disaster. Based on the captions and clues in the images, they arrange them in sequential order. While viewing the completed sequence of images, students reflect on what it might have been like to be there, and ask themselves: what were people thinking, doing and saying at each point? This activity assists students in gaining an understanding of how devastating nuclear meltdowns can be, which underscores the importance of responsible engineering. It is recommended that this activity be conducted before the associated lesson, Nuclear Energy through a Virtual Field Trip.
To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use alcohol and chromatography paper to separate the components of black and colored marker ink. Students witness first-hand how components of a solution can be separated, even when those individual components are not visible in solution.
The resource "Circuit analysis overview" is included in the "Electrical engineering" course from Khan Academy. This resource is one of the sub-topics in the "Circuit analysis" topic area.
Students are introduced to several key concepts of electronic circuits. They learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about Ohm's Law and how it is used to analyze circuits.
Students use the same method as in the activity from lesson 2 of this unit to explore the magnetism due to electric current instead of a permanent magnet. Students use a compass and circuit to trace the magnetic field lines induced by the electric current moving through the wire. Students develop an understanding of the effect of the electrical current on the compass needle through the induced magnetic field and understand the complexity of a three dimensional field system.

Our global society is not sustainable. We all know about the challenges we’re facing: waste, climate change, resource scarcity, loss of biodiversity. At the same time, we want to sustain our economies and offer opportunities for a growing world population. This course is about providing solutions we really believe in: a Circular Economy.
In this course we explore the Circular Economy: how businesses can create value by reusing and recycling products, how designers can come up with amazingly clever solutions, and how you can contribute to make the Circular Economy happen.
Building construction is one of the most waste producing sectors. In the European Union, construction alone accounts for approximately 30% of the raw material input. In addition, the different life-cycle stages of buildings, from construction to end-of-life, cause a significant environmental impact related to energy consumption, waste generation and direct and indirect greenhouse gas emissions.
The Circular Economy model offers guidelines and principles for promoting more sustainable building construction and reducing the impact on our environment. If you are interested in taking your first steps in transitioning to a more sustainable manner of construction, then this course is for you!
In this course you will become familiar with circularity as a systemic, multi-disciplinary approach, concerned with the different scales, from material to product, building, city, and region.
Some aspects of circularity that will be included in this course are maximizing reuse and recycle levels by closing the material loops. You will also learn how the Circular Economy can help to realign business incentives in supply chains, and how consumers can be engaged and contribute to the transition through new business models enabling circular design, reuse, repair, remanufacturing and recycling of building components.
In addition, you will learn how architecture and urban design can be adapted according to the principles of the Circular Economy and ensure that construction is more sustainable. You will also learn from case studies how companies already profitably incorporate this new theory into the design, construction and operation of the built environment.
Around the world, major challenges of our time such as population growth and climate change are being addressed in cities. Here, citizens play an important role amidst governments, companies, NGOs and researchers in creating social, technological and political innovations for achieving sustainability.
Citizens can be co-creators of sustainable cities when they engage in city politics or in the design of the urban environment and its technologies and infrastructure. In addition, citizens influence and are influenced by the technologies and systems that they use every day. Sustainability is thus a result of the interplay between technology, policy and people’s daily lives. Understanding this interplay is essential for creating sustainable cities. In this MOOC, we zoom in on Amsterdam, Beijing, Ho Chi Minh City, Nairobi, Kampala and Suzhou as living labs for exploring the dynamics of co-creation for sustainable cities worldwide. We will address topics such as participative democracy and legitimacy, ICTs and big data, infrastructure and technology, and SMART technologies in daily life.
