12.742 Marine Chemistry (MIT) 12.742 Marine Chemistry (MIT)

Description

Includes audio/video content: AV selected lectures. This course is an introduction to chemical oceanography. It describes reservoir models and residence time, major ion composition of seawater, inputs to and outputs from the ocean via rivers, the atmosphere, and the sea floor. Biogeochemical cycling within the oceanic water column and sediments, emphasizing the roles played by the formation, transport, and alteration of oceanic particles and the effects that these processes have on seawater composition. Cycles of carbon, nitrogen, phosphorus, oxygen, and sulfur. Uptake of anthropogenic carbon dioxide by the ocean. Material presented through lectures and student-led presentation and discussion of recent papers. Includes audio/video content: AV selected lectures.

11.479J Water and Sanitation Infrastructure in Developing Countries (MIT) 11.479J Water and Sanitation Infrastructure in Developing Countries (MIT)

Description

This course deals with the principles of infrastructure planning in developing countries, with a focus on appropriate and sustainable technologies for water and sanitation. It also incorporates technical, socio-cultural, public health, and economic factors into the planning and design of water and sanitation systems. Upon completion, students will be able to plan simple, yet reliable, water supply and sanitation systems for developing countries that are compatible with local customs and available human and material resources. Graduate and upper division students from any department who are interested in international development at the grassroots level are encouraged to participate in this interdisciplinary subject.

Eutrophication Eutrophication

Description

Managing eutrophication is a key element in maintaining the earths biodiversity. Eutrophication is a process mostly associated with human activity whereby ecosystems accumulate minerals. This free course explains how this process occurs, what its effects on different types of habitat are, and how it might be managed. First published on Tue, 22 Mar 2016 as Eutrophication.

Health promotion, health education and HIV/AIDS

Description

This article will focus on the role that health promotion can play in preventing the transmission of HIV. The school setting is taken as an example and a range of effective methods and approaches focusing on young people are identified. It gives an outline of the nature of health promotion, followed by consideration of school-based efforts, which aim to protect the future generation, and a summary of some of the strategies that have been effective in this setting. Finally, issues related to health and monitoring health status are then very briefly addressed.

Cu-4.5 wt% P

Description

This is an example of a hypoeutectic alloy. On slow cooling the liquid first solidified at approximately 940C as copper rich dendrites. The composition of the remaining liquid became increasingly rich in phosphorus until it solidified as a eutectic (8.38 wt% P) at the eutectic temperature of 714C. Note that the dendrites are cored - the different contrast after etching indicated that the composition varies with position in the dendrites. This is caused by non-equilibrium solidification. The cooling rate was too rapid for equilibrium to be maintained between the solid and the liquid phases. This alloy has no practical applications. Phosphor bronzes usually contain 5 wt% Sn for solid solution strengthening with 0.2 wt% P for interstitial solution strengthening. They have high strength an

Cast iron, containing phosphorus

Description

The presence of phosphorus in cast iron has no great effect on the graphite cementite ratio but serves to make the metal very fluid due to the creation of a low melting point phosphide eutectic. This may result in shrinkage porosity in large castings. Manganese serves to remove sulphur from the casting and since sulphur promotes cementite, the manganese will harden the iron.
