One such process is the TAP process, the basic patent being held by Dow. It was developed in Japan by Asahi in conjuction with Toshiba. Foam expansion after mould filling is made possible by use of retractable mould cores. Because of the difficulty of allowing expansion in more than one direction this process has been largely limited to the production of flat products. Efficient gas sealing systems are also vital and the process needs close control. For this reason it has not been widely used in either Europe or North America. 

STM has particularly great potential for in situ chemical studies. While our present knowledge of the atomic structure of catalyst surfaces is largely limited to those structures which are stable in ultra-high vacuum before and after reaction, STM may provide an insight into both adsorbate and catalyst surface structure in situ during the reaction. The following issues to be characterized by STM may be most relevant to characterization of catalysts and catalysis ... 

The reaction has a broad scope and is currently being widely applied in fine chemicals manufacture. One limitation is that the arylating agent is largely limited to relatively expensive aryl bromides and iodides (see, however, Reetz et al, 1998), while the process... 

Although they are much more common than was at one time believed, molecules of the non-metallic elements with an LLP coordination number of greater than four are nevertheless relatively rare. They are very largely limited to the halides, particularly the fluorides, chlorides,... 

Currently, our understanding and the guidelines extracted from phase space considerations are largely limited to a qualitative level. Further development is needed to... 

The coverage of the survey has though been deliberately restricted to those sandwich systems in which the pseudo-axial structure is definitely established or is strongly indicated by the available evidence, and species in which extensive distortion from this geometry is likely have thus been excluded. Consequently this has had the effect of largely limiting the coverage to the metallocenes and bisarene compounds of the 3d series since in the 4c and... 

It would seem that normally the oxidation of ketone bodies would proceed largely to completion in the liver by the ketolytic mechanism. Whenever the supply of carbohydrates here is sufficiently reduced, appreciable amounts of ketones then escape oxidation and pass into the blood. When the concentration of ketones becomes sufficiently elevated, a ketonuria occurs and also some ketones will be utilized by the tissues. Such a theory would largely limit the ketolysis mechanism to the liver. It would explain the specificity of the sugars in preventing ketonuria and the discrepancy between the amount of D-glucose required to prevent ketosis and the caloric value of the fat spared. It is further supported by the demonstration that the liver is capable of exhibiting ketolysis. 

Poor operational stability due to drift has largely limited the long-term or implantable application of pH sensors. Some oxide-based electrodes present very high initial...

Lewy body pathology is also the defining feature of several other, rarer diseases, such as Lewy body dysphagia and pure autonomic failure. In these diseases, Lewy bodies and neurites are largely limited to the enteric and peripheral nervous systems. In Parkinson s disease, Lewy body pathology is also present in the enteric and autonomic nervous systems. 

Infrared diode laser spectroscopy has been used for the measurement of hydrocarbon and CO concentrations in exhaust (13, 14, 15). The adsorption path length, and thus the absorption cell volume, required for hydrocarbon measurement is rather large, limiting the time-resolution of the measurement. The absorption path length required for CO measurement, however, is relatively short and approximately equal to the diameter of a standard exhaust pipe. This allows CO to be measured with high time-resolution by an infrared laser beam passed through an...
