Apart from the biological implications, aspects of the chemistry of macrocyclic ligands are of relevance to a diverse number of other areas. Indeed, there has been a remarkable expansion of research involving these other areas during recent times. Many of the developments impinge on topics such as metal-ion catalysis, organic synthesis, metal-ion discrimination, and analytical methods, as well as on a number of potential industrial, medical and other applications. 

He is known worldwide for his expertise in the development of a broad range of products based on hydrophilic polyurethane and has authored a book on the subject. He has published a number of papers on the use of polyurethanes in medical and other applications. He has conducted seminars in the U.S. and Europe on the medical applications of specialty polyurethanes. He has been an invited speaker to a number of conferences and seminars. 

These general comments apply to polymer science in general, but we are concerned with the specific advantages of polyurethanes. In the remainder of this chapter, we will discuss the components of a polyurethane, the process and other factors that affect the polymer, and the chemical factors that confer efficacy for environmental, medical and other applications. 

Domestic woolly sheep are bred for wool and meat in large quantities in Australia, New Zealand, and other agricultural countries. The skins are byproducts, and their conversion into high-quality fur or leather can be regarded as beneficial waste management. Lambskins and sheepskins have grown markedly more popular in recent years for clothing, automotive seat covers, medical, and other applications. Woolly sheepskins account for about half of total fur production and are processed on an industrial basis. 

Over the next few years, it is probable that the number of structures will increase significantly due to the interest of different research groups in heme peroxidase structure-function relationships. Much of this knowledge is being and will be used by different research entities, both academic and commercial, to develop biotechnological, environmental, medical, and other applications based on these enzymes.

Nanotechnology is not simply about working with materials like gold at the nano level. It is about taking advantage of these differences at the nanoscale to create markers and other new structures that are of use in a wide variety of medical and other applications. 

The light output of CsI(TI) peaks at about 565 nm, well beyond the optimum sensitivity for the normal photomultiplier tubes. For this reason, the light output is effectively low. To alleviate this problem, a photodiode detector can be used and the fact that that the light output is greater than that for Nal(Tl) can be capitalized on. CsI(Tl) detectors mounted on photodiodes are now produced commercially but their size is limited by the size of the photodiodes currently available. The small size and rugged nature of such devices makes them ideal for medical and other applications where space is at a premium. 

ABSTRACT Eddy current (contactless) measurements, especially in the form of the impedance spectroscopy, could be elfectively used to determine the electrical properties, including conductivity, of various materials, tissues and objects in many industrial, medical and other applications (e.g. coin validation). One important aspect is to have the cahbration standards for the adjustment of eddy current instrumentation to guarantee repeatabUity and comparability of the measurements. In the paper, there is described an experimental study carried out to find the ways to improve and correct the theoretical eddy current models for the single coil above the metal plate setup, designed for measurements without using of the reference metal specimen with known electrical properties. The final results show, that the accuracy of measurement with a single-coil setup can be better than 0.5% in the 60 to 500 kHz frequency range and 3.0% at the frequencies up to 10 MHz, all valid for conductivity values from 2.5 to 25 MS/m. 

Single-walled nanotubes have gained much interest recently with regard to medical and other applications. However, toxicological research has not progressed to the point where occupational exposure levels can be developed. Therefore, scientists have exposed laboratory rats to concentrations that are equal to the safe occupational limits of other fine particulate matter, such as quartz and carbon black, to evaluate the applicability of these limits to single-walled nanotubes. Results suggest...
