Indigenous Spiritual Wellbeing - Our history - Primary health care
A learning resource that explores the history of primary health care including beginnings, developments and significant declarations, goals and aims.
SP.721 D-Lab: Development, Dialogue and Delivery (MIT)
D-Lab is a year-long series of courses and field trips. The fall class provides a basic background in international development and appropriate technology through guest speakers, case studies and hands-on exercises. Students will also have the opportunity to participate in an IAP field trip to Haiti, India, Brazil, Honduras, Zambia, Samoa, or Lesotho and continue their work in a spring term design class. As part of the fall class, students will partner with community organizations in these count
21H.443 European Imperialism in the 19th and 20th Centuries (MIT)
From pineapples grown in Hawaii to English-speaking call centers outsourced to India, the legacy of the "Age of Imperialism" appears everywhere in our modern world. This class explores the history of European imperialism in its political, economic, and cultural dimensions from the 1840s through the 1960s.
21L.448J Darwin and Design (MIT)
This subject offers a broad survey of texts (both literary and philosophical) drawn from the Western tradition and selected to trace the immediate intellectual antecedents and some of the implications of the ideas animating Darwin's revolutionary On the Origin of Species. Darwin's text, of course, is about the mechanism that drives the evolution of life on this planet, but the fundamental ideas of the text have implications that range well beyond the scope of natural history, and the assumptions
21H.931 Seminar in Historical Methods (MIT)
This subject is designed to give 21H majors and minors an introduction to the methods that historians use to interpret the past. We will focus on two areas: archives and interpretation. In our work on archives, we will ask what constitutes an archive. We will visit one or two local archives, speak with archivists, and assemble our own archive related to life at MIT in 2003. Once we have a better understanding of the possibilities and limitations of historical archives, we will turn to the task o
21H.225J Gender and the Law in U.S. History (MIT)
This subject explores the legal history of the United States as a gendered system. It examines how women have shaped the meanings of American citizenship through pursuit of political rights such as suffrage, jury duty, and military service, how those political struggles have varied for across race, religion, and class, as well as how the legal system has shaped gender relations for both women and men through regulation of such issues as marriage, divorce, work, reproduction, and the family.

TALAT Lecture 1100.01: Introduction: Aluminium, a Light Metal
This lecture provides basic information about the history of aluminium, the principles behind the production of primary metal, environmental properties, potential applications, areas of application. The lecture is recommended for those situations, where a brief, general background information about aluminium is needed as an introduction of other subject areas of aluminium application technologies. This lecture is part of the self-contained course "Aluminium in Product Development", which is trea
Silal
This sample shows the typical structure of silal, irons with high Si content (5.5-7.9 wt%). It is a grey cast iron alloyed with 4-6wt% Si to provide good oxidation resistance. The high Si content forms a dense, adherent iron silicate surface film, which is resistant to oxygen penetration. The flake graphite iron Silal was one of the first heat resisting cast irons developed. Spheroidal graphite Si irons have higher strength and improved ductility. The structure shows cored dendrites of ferrite w

Birefringence in a film of polypropylene
The colours in the image are the result of birefringence and relate to the residual stress in the film, following the biaxial stretching process. The uniformity of the colour (with contrast only where an additional thickness of film exists or where wrinkling has resulted in a different apparent thickness) is indicative of both a uniform film thickness and of the uniformity of the drawing process used to make the film. Note that unlike polyethylene, the film has not been permanently strained in t

Modeling grain growth with soap bubbles
A box containing some soap solution is used to simulate a grain structure. Rigorous agitation will produce an initial structure of many small bubbles (grains), whose evolution can be recorded. The soap film that separates bubbles has a surface energy, and the area of this will tend to be minimised.
21H.466 Imperial and Revolutionary Russia: Culture and Politics (MIT)
At the beginning of the eighteenth century Russia began to come into its own as a major European power. Members of the Russian intellectual classes increasingly compared themselves and their autocratic order to states and societies in the West. This comparison generated both a new sense of national consciousness and intense criticism of the existing order in Russia. In this course we will examine different perspectives on Russian history and literature in order to try to understand the Russian E
Interdisciplinary Science Earth Through Time Student Document
The Earth Through Time module examines our planet in terms of its major systems; the atmosphere, hydrosphere, cryosphere, geosphere and the biosphere, all of which are constantly interacting. The module explores the topic of climate change throughout Earth’s history; climate change is not just a contemporary phenomenon, it has happened in the geological past at times abruptly and catastrophically.
AlgTop11: Rational curvature, winding and turning
This video introduces an important re-scaling of curvature, using the natural geometric unit rather than radians or degrees. We call this the turn-angle, or tangle, and use it to describe polygons, convex and otherwise. We also introduce winding numbers and the turning number of a planar curve.
This is the 11th lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J WIldberger at UNSW.

Delamination cracks in h-BN particles.
h-BN particles were subjected to compressive stress in the (0001) planes (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Su
