1.2.6 Summary of Section 1.2 Many people wish to limit the number of their offspring, and so resort to contraceptive measures. Chemical contraceptives interrupt the production of gametes, or prevent implantation. Mechanical or barrier contraceptives prevent egg and sperm from meeting and, in the case of IUDs, prevent implantation. Surgical methods of contraception involve physical alteration of the reproductive tract so as to prevent eggs and

24.03 Good Food: The Ethics and Politics of Food Choices (MIT)
This course explores the values (aesthetic, moral, cultural, religious, prudential, political) expressed in the choices of food people eat. It analyzes the decisions individuals make about what to eat, how society should manage food production and consumption collectively, and how reflection on food choices might help resolve conflicts between different values.
7.1:Relative and absolute comparisons The distinction between relative and absolute comparisons is an important one that has run through this course. Here, its meaning and significance will be made more explicit. The subsection begins with examples which illustrate the difference between absolute and relative measures, and you will be asked to reflect on why calculating in relative terms is often a better way to make a fair comparison. Start with a simple example based on comparison of births between countries. In 2002, the

Protestant Reformation - History and Impact
When Martin Luther accused the Catholic Church of ninety-five abuses, in 1517, his actions started a societal revolution, not just a religious reformation. This video, from the BBC, explains how significantly that movement changed the world. (54:58)
1 Natural groups Darwin made extensive observations on a great many creatures, including mammals, and noticed that species fell into natural groups, e.g. lions, tigers and leopards have many similarities, and resemble cats. On the basis of his observations, he was able to place mammals in distinct groups. His work has continued, and we now recognise that mammals have evolved from a common ancestor, and have branched into many different groups, or ‘Orders’. The animation below shows the different O

In what ways do they offer contrasting interpretations of the events Using genetics to fight ash dieback El sol de la nit. El mar 3D Printing at DuBois 4.1 Glucose metabolism We are now in a position to draw together the major concepts and components of signalling, and show how they operate in one well-understood system, namely the regulation of the storage or release of glucose in the human body. From this, you will be able to recognize archetypal pathways represented in specific examples, you will be able to appreciate how the same basic pathways can be stimulated by different hormones in different tissues, and you will see how opposing hormones activate separat 1 Why is information security important? This course introduces you to information security and its management. A succinct definition of information security might run as follows: Information security is the collection of technologies, standards, policies and management practices that are applied to information to keep it secure. But why is it important to secure information? And how should its security be managed?

The Du Bois Library has teamed up with MakerBot to create a 3D printing center where students and faculty, along with the community, will have access to equipment including scanners and printers. The collaboration links the campus and its entrepreneu
This class will study the behavior of photovoltaic solar energy systems, focusing on the behavior of "stand-alone" systems. The design of stand-alone photovoltaic systems will be covered. This will include estimation of costs and benefits, taking into account any available government subsidies. Introduction to the hardware elements and their behavior will be included.
