5.1 Pollution and loss of biodiversity
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef

RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain

Co-operation and contestation: farmer-state relations in agricultural transformation, An Giang Provi
This thesis analyses farmer-state, and farmer-farmer relations in the Mekong Delta, Vietnam, focusing on agricultural transformations in An Giang Province. It does so at three levels: first, at the largest scale, farmer-state relations are explored through the building of common dikes of different heights; second, farmer-farmer relations are examined through farmers’ management of flood water within common August dikes; and third, at the smallest scale, the scope for interhousehold diversific
