Technology complicated

Mass spectrometry offers the advantage of detecting all parameters of interest with the same delay. Influences caused by water or secretions are similar to those with other sidestream monitors. New generation devices avoid previous problems of vacuum technology, complicated handling, and calibration. The market potential remains uncertain. [Pg.384]

Such alloy can be obtained without technological complications using rigorous monitoring of the flow of silica into the cell. [Pg.86]

The pronounced degradation of the release agents (entailing the formation of deposits) in the molds, so that even short mold cleansing cycles lead to a substantial technological complication. ... [Pg.229]

The computerised ultrasonic P-scan system (FORCE Institute, Denmark) has been in operation in Ukraine since 1992. Over this period rather extensive new technological experience has been accumulated of solving the complicated tasks of reliability of the constructions the design life of which is over. [Pg.790]

Calibrating the electrode presents a third complication since a standard with an accurately known activity for H+ needs to be used. Unfortunately, it is not possible to calculate rigorously the activity of a single ion. For this reason pH electrodes are calibrated using a standard buffer whose composition is chosen such that the defined pH is as close as possible to that given by equation 11.18. Table 11.6 gives pH values for several primary standard buffer solutions accepted by the National Institute of Standards and Technology. [Pg.492]

Most continuous pressure filters available (ca 1993) have their roots in vacuum filtration technology. A rotary dmm or rotary disk vacuum filter can be adapted to pressure by enclosing it in a pressure cover however, the disadvantages of this measure are evident. The enclosure is a pressure vessel which is heavy and expensive, the progress of filtration cannot be watched, and the removal of the cake from the vessel is difficult. Other complications of this method are caused by the necessity of arranging for two or more differential pressures between the inside and outside of the filter, which requires a troublesome system of pressure regulating valves. [Pg.405]

There is a good chance that you have had some contact with geographic information systems (GIS). A GIS is a computer representation of a system that uses all pertinent survey and database information to generate intelligent maps and queries. Much has been published on the subject. In addition there are many vendors of the technology and many seminars. GIS is a complicated subject. Several early GIS projects were not successful. Often GIS projects are very expensive. [Pg.392]

Using formalized risk assessment techniques for industrial ventilation projects may complicate the issue more than necessary. The work environment and its exposure conditions are the focus. However, when evaluating new technology, including waste management, the risk assessment approach may be valuable. [Pg.1369]

When the products are partially or totally miscible in the ionic phase, separation is much more complicated (Table 5.3-2, cases c-e). One advantageous option can be to perform the reaction in one single phase, thus avoiding diffusional limitation, and to separate the products in a further step by extraction. Such technology has already been demonstrated for aqueous biphasic systems. This is the case for the palladium-catalyzed telomerization of butadiene with water, developed by Kuraray, which uses a sulfolane/water mixture as the solvent [17]. The products are soluble in water, which is also the nucleophile. The high-boiling by-products are extracted with a solvent (such as hexane) that is immiscible in the polar phase. This method... [Pg.264]

During the 1960s, air conditioning system control began to shift from simple electrical or pneumatic control to electronic and rudimentaiy computer control. This new technology was applied to commercial, institutional and commercial buildings where the high cost and complicated nature justified its use. [Pg.28]

Fluid power systems have developed rapidly over the past thirty-five years. Today, fluid power technology is used in every phase of human existence. The extensive use of hydraulics to transmit power is due the fact that properly constmcted fluid power systems possess a number of favorable characteristics. They eliminate the need for complicated systems of gears, cams, and levers. Motion can be transmitted without the slack or mechanical looseness inherent in the use of solid machine parts. The fluids used are not subject to breakage as are mechanical parts, and the mechanisms are not subjected to great wear. [Pg.584]
