Her immediate reaction was "how do you make a water garden in a limited space, especially in congested cities. Water gardens are only for those houses built in really wide-open spaces, and plenty of land where you can go high, wide and free, making a water garden." Unfortunately, that is the mindset of a number of people out there, who are under the impression that you need plenty of land in which to make a water garden. That is because the moment you say this word water garden, you visualize a huge pool, in which a number of exotic plant species float. You may also find some Koi goldfish moving leisurely to and fro, and people appreciating that garden while walking around it leisurely of an evening. Well, that may be all right for a hotel lobby, where no expenses are spared. However, ordinary water gardens can be made right in your back yard, in the limited space, and with a little bit of creative gardening. I told my friend that a water garden could be made in the amount of space, in which she wanted to erect a water fountain, and she blinked. What is the fun of a small water garden was her immediate response. I replied, "Just think about it. After all, you are planting some attractive plant species which are growing in water. This is a contrast to the plants growing on land. You do not have any kids, and you do not have any pets which may find them taking a ducking in that water garden. So think about it. " She did. And now she has a small water garden in her backyard. It has water lilies and lotuses goldfish and even tadpoles in it. Also a Walt Disney statue of Snow white's pal Dopey looking at his reflection in his typical dopey fashion. The idea of water gardening is definitely not a modern concept. Since millenniums, water gardens have been a part of garden layouts. Be they the palaces of Caesar, in Greece, or a castle in Spain, or a manor in Britain or perhaps the palace of Kublai Khan, you could be certain that there would be a water garden built there, and tended carefully and lovingly by all the gardeners.
This book is the result of a long-term co-operative research and professional development programme between the Instituto de Investigaciones Electricas (IIE), Mexico, and the University of Salford, UK. It provides the design basis for the fabrication of small and large scale commercial absorption heat pump systems, and includes a comprehensive treatment of the economics of heat pump systems. It charts the development of heat pump technology from theoretical principles to the operation of practical systems for the purification of water, both for human consumption and a wide variety of industrial purposes.
Two methods for the detection of important human pathogens, Cryptosporidium parvum and Helicobacter pylori, were investigated: a fiber optic biosensor, and real time PCR. The mechanism for specific detection in both methods is recognition of specific DNA sequences in the target organisms. The biosensor that was used, the Analyte 2000, was originally developed for the detection of chemicals. It utilizes a fiber optic wave guide that propagates an evanescent light wave of very specific wavelength. The light excites fluorescent molecules bound to the waveguide, but not in the bulk solution, which theoretically enhances signal while reducing background interference. Attempts to develop this system for the detection of DNA were not successful due to poor detection of the target molecules. An assay analogous to a sandwich immunoassay was designed for use on the Analyte 2000. Specific oligonucleotide probes were designed to bind to the waveguides via biotin-streptavidin interaction, and were used to capture the target DNA. Pure target DNA representing unique genes in the organisms were synthesized by PCR. Detection of captured DNA was then attempted using an oligonucleotide detection probe designed to bind to the target. Two detection systems were employed: an indirect signal amplification system based on biotin-tyramide deposition, or direct detection of fluorescent signal from Cy-5 molecules. In all experiments performed there was very little difference between the signal generated with or without the target molecules. Many experiments were conducted to attempt to identify reasons for the poor signal. Signal was only of any significance when target amplicons were internally labeled with Cy-5 by PCR. Real time PCR as a method to detect the pathogens was also investigated. Though the PCR technique itself is very rapid, DNA extraction and purification requires preparation time. Filtration of up to one liter of well water, followed by concentration and "cleaning" Helicobacter pylori cells by immunomagnetic separation, was used to detect H. pylori seeded in a water source. Following cell lysis, the extracted DNA could be used directly in conventional PCR targeting the 16S rRNA gene to detect less than 265 cells per liter of water. DNA purification was not required for this level of detection. Initial studies to amplify lysed cells by real time PCR indicated that an incorrect product was made. When purified DNA was used for real time PCR, the correct product was produced from DNA representing as few as 100 cells.
