Such a model becomes possible as the size of computing devices decreases and their power increases, with wireless...

.... Seasonal growth has large effects on the concentration of carbon dioxide in the air, and on the surface life of the planet— see Carbon cycle and Biosphere from space . Because the leaves of land plants adapt to changing carbon dioxide levels, fossil leaves can help to monitor past changes— see Carbon cycle . The ecology of plant life looms large among the anxieties about the state of the planet, but fundamental issues remain in dispute— see Biodiversity . Ecologists have become acutely aware of the importance of controlling the numbers of plant...

...Soddy (briefly lecturer in chemistry, a chance visitor from England), and Otto Hahn (a determined visitor from Germany)—Rutherford discovered the emanation, radon, and its active deposit (with Owens); invented the disintegration theory of radioactive decay (with Soddy); and monitored the sequence of decay products (with Hahn). Rutherford set forth the principles of radioactivity in a textbook, first published in 1904 , which defined the field for decades. In 1907 Rutherford left Montreal for the professorship of physics at the University of Manchester,...

...air movement, and light produced by a rise or fall of the barometer can all be picked up, consciously or unconsciously, by traditional sense organs. The eye , acting as a light meter, by way of the small number of optic nerve fibres that run directly to the hypothalamus , can monitor the drop in light intensity as cloud cover builds up. The skin , with its hair follicles and many free nerve endings, might be responsible for ‘Pos-Ion’ sensitivity and for sensing the excess of negative charge associated with good weather. Neural centres for integrating such...

...but improving knowledge of the state of local or regional crustal stress increases our ability to foretell these shocks, as does surveying visible expressions of earthquakes, such as fault scarps. Most geological survey organizations include units concerned with this aspect of monitoring. In addition to producing maps of both outcrop and subsurface geology, geophysical characteristics, and mineralogical and geochemical maps, geological surveying has, since the 1950s, been extended to the continental shelves adjacent to land masses. This activity has been driven...

...anaesthesia, have become available in disposable versions, minimizing the risk of infection being transferred from one patient to another. Another major development, commencing in the 1970s, has been the increasing availability of apparatus which allows the anaesthetist to monitor routinely not only the patient's pulse rate, blood pressure, and electrocardiogram, but also such physiological parameters as the oxygen and carbon dioxide levels in the blood. This, together with the measurement of blood loss during operations, provides an early warning of...

In this way, the resulting image is built up point by point, usually electronically on a video monitor or similar display device. Microscopes in this class include the scanning electron microscope, the acoustic microscope, the confocal light microscope, and a wide variety of scanning probe microscopes, including the scanning tunnelling microscope and the atomic force microscope,...

...and stored the donors of the gametes now have to record what should happen in such eventualities. Ovulation induction is a method of assistance for women who are not producing eggs. Drugs (gonadotropins) which stimulate the ovary to produce eggs are used. The dose is care-fully monitored by ultrasound scanning of the ovary and the measurement of hormones in the blood. There are many ethical dilemmas arising out of assisted reproductive methods and the developments therefrom, many of which were not foreseen. Society has to consider which advances are acceptable...

...NASA, Tucker had traced the origin of the vegetation signature to the optical architecture of leaves. He concluded that the satellites don't merely map vegetation. From high in the sky they measure, region by region, its light-harvesting capacity. In effect the sensors in space monitor the combined activity in all the leaves of the green chlorophyll pigment. This absorbs the solar energy needed for the basic work of life on the planet, to make sugars from carbon dioxide and water, and release oxygen as a by-product. As plants retain no more chlorophyll than...

...the sky was compromised during sunstorms, with communications blackouts occurring especially at high latitudes. In 1942 , British radar operators thought that the Germans were jamming their sets, but it turned out to be the Sun emitting strong radio waves. Thereafter you could monitor the Sun's general storminess by its radio intensity, with less eyestrain than by counting sunspots. Magnetic storms ceased to be a harmless curiosity when they encountered the long metal structures being created by 20th-century technology, and induced strong electric currents in...

...regarded the philosophical faculty as the “lowest” of the four, offering primarily preparatory study for the three “higher” faculties, each of which trained students for particular professions. The faculties maintained the boundaries between branches of knowledge, and all four monitored a common boundary that kept the mechanical arts outside the university. Teaching took place by lecture (the reading of an authorized text by the regent master or professor), commentary, and disputation (an oral debate conducted in Latin according to the rules of Aristotelian...

...mammals produce a great deal of heat within their bodies by physiological means: indeed, it is estimated that fully nine-tenths of what we eat is devoted to temperature control (which is why a crocodile consumes one-tenth of what a human does). The heat production is closely monitored to maintain a precisely constant body temperature. In other words, mammals are endothermic (‘internal heat’) homeotherms (‘constant temperature’). Different species of mammals maintain different temperature set points, but these are generally in the range 35–40 °C, and small...

...contrast to the curricula found in secular, modernist, or government-sponsored schools. The tensions created by Westernization in Muslim societies became fertile grounds for the mushrooming of such religious schools in rural as well as urban areas. Without a central authority monitoring these schools, the curriculum and pedagogies came to be, and remain, driven by the local religious authorities or by religious functionaries who volunteer oversight. These movements to revive traditional Islam were predominantly led by men, which had detrimental effects on...

...take months to melt and are thus important sources of summer water for many arid regions. Monitoring the extent, depth, and water resources contained in the snow cover is done using a variety of tools. Because snow is white with a high albedo, it is easy to differentiate snow-covered from snow-free land using satellites. The hemispheric extent of the snow cover has been tracked this way since 1967 and provides an important record of climate. Snow cover depth is monitored at thousands of weather stations. These data are used with reanalysis models to produce...
