Methods of improvement

Gravity override of low density steam leads to poor volumetric sweep efficiency and low oil recovery in steam floods. Nonchemical methods of improving steam volumetric sweep efficiency include completing the injection well so steam is only injected in the lower part of the oil-bearing zone (181), alternating the injection of water and steam (182), and horizontal steam injection wells (183,184). Surfactants frequently are used as steam mobihty control agents to reduce gravity override (185). Field-proven surfactants include alpha-olefin sulfonates (AOS), alkyltoluene sulfonates, and neutralized... 

Two general methods of improving polymer hemocompatibility are known (1) grafting of hydrophilic chains, and (2) the chemical attachment of an antiplatelet agent. In this respect, many hydrophilic and other monomers are grafted on solid polyurethane surfaces such as... 

The second method of improving the power factor of an installation is to provide static capacitor banks. These can be installed as a single block at the point of supply busbar, as a set of switchable banks or as individual units connected to specific loads. For an installation where no synchronous machines are installed for other purposes (i.e. as prime movers or generators) then static capacitor banks are almost invariably the most cost-effective way of improving the power factor. 

If, after assessing the various computer and software packages, the decision is made to implement the proposed maintenance system on computer rather than by manual methods caution must be exercised. Irrespective of the above-mentioned benefits, the use of a computer does not increase work output but it does provide the department with a very sound method of improving the management of the company s assets and resources. 

One general method of improving the performance of plastic products in impact loading is to prevent, by design and handling, the formation of notched areas which act as stress...

The efficient and effective organic farmers who were interviewed in connection with this book all had a very clear idea of the monthly cash flow. Methods of improving the availability of cash are listed below. 

One method of improving G/S contacting consists of showering solids in dilute suspension from the top into an upflowing gas stream. Experiments verified that gas/solid heat transfer coefficient for such a system is essentially the same as for the discrete particles, and that pressure drop for gas flow is extremely low. 

Methods of improving the detection limits for anions by preconcentration are reviewed in Table 2.6. 

Intelligent process control based on platinum temperature sensors and tailored electronics provides an effective method of improving both kitchen safety and the user friendliness of kitchen appliances, and also contributes to reducing energy consumption. 

The process parameters influencing droplet sizes may include liquid pressure, flow rate, velocity ratio of air to liquid (mass flow rate ratio of air to liquid), and atomizer geometry and configuration. It has been clearly established that increasing the velocity ratio of air to liquid is the most important practical method of improving atomization)211] In industrial applications, however, the use of mass flow rate ratio of air to liquid has been preferred. As indicated by Chigier)2111 it is difficult to accept that vast quantities of air, that do not come into any direct contact with the liquid surface, have any influence on atomization although mass flow rates of fluids include the effects of velocities. 

A standard method of improving on the Hartree-Fock description is the coupled-cluster approach [12, 13]. In this approach, the wavefunction CC) is written as an exponential of a cluster operator T working on the Hartree-Fock state HF), generating a linear combination of all possible determinants that may be constructed in a given one-electron basis,... 

The Chemical Manufacturers Association established an Air Quality Committee to study methods of improving the air that could be implemented by chemical manufacturers. 

Efficient biocatalysis in neat organic solvent depends on the careful choice of the method of dehydrated enzyme preparation and solvent used. Optimization of these factors towards a given transformation is often known as catalyst formulation and solvent, or medium, engineering respectively, both of which will be briefly discussed below. Catalyst engineering which also provides a powerful method of improving activity and stability, is discussed in Chapter 2. 

One method of improving the COP of the refrigerator-freezer eombination is to employ an evaporator for both the refrigerator region and the freezer region with a single compressor, as illustrated in Fig. 6.20. A numerical example of this arrangement is shown in Example 6.10. 

Gahn was a man of broad interests who often laid aside the Philosophical Transactions or his blow-pipe to read aloud, near the sewing-table in the next room, now a poem by Kellgren, Fianzen, Fru Lenngren, Leopold, or Voltaire, now a comedy by Molibre or Holberg or to exhibit a litde mechanical or optical masterpiece or to study the instruments for some household art and present a method of improving diem (44).

Clearly the procedures of the laboratories involved in this project could be improved. Before suggesting methods of improvement, one obvious point should be stressed. The results of this study do not vitiate the use of data between laboratories they merely indicate that the data should be used with caution. For example, in the Luristan bronzes (14), the arsenic content of arsenical copper artifacts is said to drop from 2-6% to 2% and below after a tin-copper alloy was introduced about 2600 B.C. If another laboratory analyzes a copper alloy object and finds, say 4.9% arsenic (and all other factors agree), the object can be confidently set into the earlier group if the laboratory finds 0.8% arsenic, the object could be set into the later group. If the arsenic content is 1.95%, the grouping into which it would fall is less unequivocal, and other factors...
