5.14 Desalination

In many parts of the world, surface water or non-saline groundwater stocks are not adequate to satisfy the water demand. While one may immediately think of the Middle East as being one such area, it is less obvious that many islands (e.g. the Canary Isles, Madeira, the Channel Islands) also suffer the same problem. In such circumstances, people have been forced to consider the sea and brackish underground aquifers as water sources. To make these saline waters potable, the salt has first to be

Human-Robot Collaboration in Manufacturing

Recent advances in computation, sensing, and hardware enable robotics to perform an increasing percentage of traditionally manual tasks. Yet, often the worker cannot be removed entirely from the process. This provides new economic motivation to explore opportunities where people and industrial robots may work in close physical collaboration. This talk focuses on two new uses of advanced robotics in manufacturing: large industrial robots that move and work in the same physical space as people,

Three-Mile Long Toutatis Asteroid
Flying by the earth every four years, the three-mile long Toutatis Asteroid was captured with the Schulman-Telescope at the UA's Mount Lemmon SkyCenter, by astrophotographer and astronomy educator Adam Block. He combined several hundred exposures of 5 seconds each to make the animation.

From Plants to Parasites
UGA researchers have discovered that a small component of some tropical parasites actually evolved from ancient algae and destroying this component of the parasite renders it incapable of reproduction. This may one day lead to advanced new therapies to fight debilitating tropical diseases.

4.3 Reducing the nutrient source

Europe is the continent that has suffered most from eutrophication, and increasing efforts are being made to restore European water bodies damaged by nutrient enrichment. If the ultimate goal is to restore sites where nature conservation interest has been damaged by eutrophication, techniques are required for reducing external loadings of nutrients into ecosystems.

Although algal production requires both nitrogen and phosphorus supplies, it is usually sufficient to reduce only one major

3.2.2 Domestic detergents

Domestic detergents are a major source of phosphorus in sewage effluents. Phosphates are used as a ‘builder’ in washing powders to enhance the efficiency of surfactants by removing calcium and magnesium to make the water ‘softer’. In 1992, the UK used 845 600 tonnes of detergent of various types, all of which have different effects on the environment. Estimates of the relative contribution of domestic detergents to phosphorus build-up in Britain's watercourses vary from 20–60%. The

3.2.1 The atmosphere

Pollution of the atmosphere has increased rates of nitrogen deposition considerably. Nitrogen has long been recognized as the most commonly limiting nutrient for terrestrial plant production throughout the world, but air pollution has now created a modern, chemical, climate that often results in excess supplies of nitrogen due to atmospheric deposition.

The main anthropogenic source of this enhanced nitrogen deposition is the NOx (mainly as NO) released during the comb

2.2 Effects on consumers in freshwater ecosystems

Increased productivity tends to increase rates of deoxygenation in the surface layer of lakes. Although phytoplankton release oxygen to the water as a byproduct of photosynthesis during the day, water has a limited ability to store oxygen and much of it bubbles off as oxygen gas. At night, the phytoplankton themselves, the zooplankton and the decomposer organisms living on dead organic matter are all respiring and consuming oxygen. The store of dissolved oxygen thus becomes depleted and diffu

7.1 Introduction

Until now, we have discussed DNA primarily as a double helix, but in its natural state within the cell it is found packaged as a complex mixture with many different proteins and other components. You have already seen examples of proteins with specific roles to play, such as topoisomerases and the proteins with various DNA binding domains, but in this section we will turn our attention to the proteins that serve to pack and organise the DNA into what we call chromatin.

Reactive oxygen species

The metabolism that occurs in every cell and is associated with the basic requirements of physiology inevitably leads to the production of reactive intermediates, many of which are capable of reacting with DNA or free dNTPs, which could subsequently be incorporated during synthesis. One particular group of such molecules are called reactive oxygen species (ROS). The essential feature of ROS is the presence of an unpaired electron on an oxygen atom in the molecule, which enables the ROS to rea
