4.4.2 Phosphate stripping It has been estimated that up to 45% of total phosphorus loadings to freshwater in the UK comes from sewage treatment works. This input can be reduced significantly (by 90% or more) by carrying out phosphate stripping. The effluent is run into a tank and dosed with a product known as a precipitant, which combines with phosphate in solution to create a solid, which then settles out and can be removed. It is possible to use aluminium salts as a precipitant, but the resulting sludge contains tox
10.8 Need to improve product or process Even though an invention will have been thoroughly tested before launch it's not possible for a company to test its performance in every situation in which it will be used. Real users are likely to discover how the product might not perform well or how it doesn't meet their needs. Once a company learns about these deficiencies it can address them through redesign. There are a number of incentives to do this: improve the product's performance in order to increase its appeal to larger numbers o
7.344 The Fountain of Life: From Dolly to Customized Embryonic Stem Cells (MIT)
During development, the genetic content of each cell remains, with a few exceptions, identical to that of the zygote. Most differentiated cells therefore retain all of the genetic information necessary to generate an entire organism. It was through pioneering technology of somatic cell nuclear transfer (SCNT) that this concept was experimentally proven. Only 10 years ago the sheep Dolly was the first mammal to be cloned from an adult organism, demonstrating that the differentiated state of a mam
Survey of London: volume 36 - Covent Garden
Covent Garden has a special significance as the birth-place of modern town planning in London. Inigo Jones’s Italianate Piazza, designed in the 1630s for the 4th Earl of Bedford, was unlike anything the capital had seen before, and provided the prototype for the laying-out of London’s suburban estates for centuries to come. Based on a detailed study of the surviving fabric and the Bedford Estate’s archives, this volume recounts the story of the Piazza’s evolution (and eventual redevelopm

3.5.2 Bacteria
Bacteria
are organisms of special significance to the study of clean and polluted waters because they break down organic matter. While most of them are not harmful to humans, some bacteria (e.g. Clostridium) are pathogenic. Most bacteria are retained on a filter of pore size 0.45 μm and all bacteria are trapped on a filter of 0.22 μm. They are important in sewage treatment, and in solid waste disposal. They are extremely abundant in almost all parts of the aquatic en
Center for Public Awareness in Bioethics (CPAB)

1.9 Conclusion If we try to recapitulate what we have done in this unit two main areas need to be considered: is there likely to be a European identity in the near future? and how important are national sentiments going to be? While it could be said that by the end of the twentieth century the EU had become a reasonably integrated economic space politically, and especially at the cultural level, progress was limited. But even at the economic level, areas like labour mobility were still very low in the

E Simultaneous equations Simultaneous equations are pairs of equations that are both true (i.e. they are simultaneously true). They are both expressed as equations with two unknowns. By making one of these unknowns the subject of both equations, we can then substitute the subject in one equation and then solve for the other unknown. Then we can substitute back into the equation and solve for the subject. 7.3 Studying protein–protein interactions The investigation of protein–protein interactions is a very important aspect of understanding proteins. Identifying binding partners can give insight into a protein's function. Many different methods and technologies have been developed to identify and characterise interactions between proteins, a few of which are described here.
