  • Chitosan oligomers were prepared by oxidative degradation of chitosan (with hydrogen peroxide) under microwave irradiation. This is convenient, friendly and effective method to prepare chitosan oligomers. By 1 H-NMR, IR spectrum, the structure of the products was identified and keeps the same as of chitosan. By LC-MS analysis, it proved that chitosan was decomposed to five fractions, the smallest one about D- glucosamine 3 units (at least).

  • Signal processing has been playing an increasingly important role in remote sensing, though most remote sensing literatures are concerned with remote sensing images. Many data received by remote sensors such as microwave and geophysical sensors, are signals or waveforms, which can be processed by analog and digital signal processing techniques.

  • The definition for dielectric constant relates to the permittivity of the material (symbol use here ε). The permittivity expresses the ability of a material to polarise in response to an applied field. It is the ratio of the permittivity of the dielectric to the permittivity of a vacuum. Physically it means the greater the polarisation developed by a material in an applied field of given strength, the greater the dielectric constant will be. Traditionally dielectric materials are made from inorganic substances eg. mica and silicon dioxide.

  • In many small and shallow aquifers the hydrochemistry does not evolve further. However, the baseline natural quality of groundwater may vary spatially within the same aquifer if the mineral assemblages vary, and also evolves with time as the water moves along groundwater flow lines. If an aquifer dips below a confining layer (Figure 2.5), a sequence of hydrochemical processes occurs with progressive distance down gradient away from the outcrop, including precipitation of some solids when relevant ion concentrations reach saturation levels for a solid mineral phase.

  • To fulfill the ever increasing demands of internet based communication network, the speed of computing as well as the speed of data processing should be high enough with the transmission medium of enormous potential bandwidth having the vast amount of information handling capabilities. On the other hand, conventional electronic technology has already reached its ultimate speed limit (40 Gb/s) through the limitations of miniaturization of chips and bandwidth limitation, and obviously it will create data traffic jam in future internet based networking services....

  • When we thus contemplate the process of social hygiene, we are no longer in danger of looking upon it as an artificial interference with Nature. It is in the Book of Nature, as Campanella put it, that the laws of life and of government are to be read. Or, as Quesnel said two centuries ago, more precisely for our present purpose, "Nature is universal hygiene." All animals are scrupulous in hygiene; the elaboration of hygiene moves pari passu with the rank of a species in intelligence. Even the cockroach, which lives on what we call filth, spends the greater part of its time in the...

  • Modern communication systems require radio frequency and microwave signals for the wireless transmission of information. These systems employ oscillators, mixers, ®lters, and ampli®ers to generate and process various kinds of signals. The transmitter communicates with the receiver via antennas placed on each side. Electrical noise associated with the systems and the channel affects the performance. A system designer needs to know about the channel characteristics and system noise in order to estimate the required power levels....
