Simple effects

Because of the increa sing worldwide interest and demand for simple, effective, and inexpensive female sterilisation, a variety of procedures and methods have been developed. These approaches differ whether they are performed postpartum, postabortum, or in interval situations. The choice of methods also largely depends upon the physician s prior training, knowledge, and experience. Excellent reviews have been written on sterilisation (98). 

Mixing, wrist shaking, or tumbling combinations offer a simple, effective, but time-consuming and not highly reproducible method of extraction. Sample-to-solvent ratios are similar to Soxhlet ratios. Although sample manipulation is reduced, this technique requires nearly as much time as the Soxhlet method. Shake-flask extraction is low cost. 

The description of the real process of dipole-orientational relaxation by one parameter xR is a first-order approximation which is far removed from reality even in studies with model solvents.(89) A set of relaxation times would exist in real systems. However, such an approximation is necessary since it allows rather simple models of relaxation to be developed and to be compared with the results of experiments. xR may be considered as a simple effective parameter characterizing the dynamic processes.

The HAVE System is a simple, effective, and low-cost technology that completely destroys the contaminants that it removes. However, variables such as pile temperature, soil characteristics, soil moisture, and porosity can negatively affect the performance of HAVE. 

This reported size is probably overestimated simple effective mass approximation used in its estimation. 

If the simple effective mass approximation does not hold, the expression 1 + mjmv is replaced by some other quantity, which also exceeds unity. 

But why is it essential to continue the wash after 5 or 10 min Because there is still a high destructive potential and lesions are still developing. This evidence shows the insufficiency of a simple effect of mechanical draining and passive dilution of a water wash. 

Perkinson, Robert R. The Alcoholism and Drug Abuse Patient Workbook. Thousand Oaks, Calif. SAGE Publications, 2003. Provides a variety of simple, effective exercises that persons in alcohol or drug abuse treatment or counseling can use to reinforce what they are learning, motivate them to stick to the program, and prevent relapses. 

A bulky substituent close to the reaction centre may increase the non-bonded compression energy as the transition state is formed this will cause an increase in A//. It will also hinder the close approach of solvent molecules to the reaction centre, thus reducing the maximum amount of stabilization possible (steric inhibition of solvation). This will result in a further increase in AH, but since decreased solvation means less ordering of solvent molecules about the transition state, there is a compensating increase in AS. Another effect of the bulky substituent may be to block certain vibrational and rotational degrees of freedom more in the (more crowded) transition state than in the initial state, and so to reduce AS. These are the most important of the simple effects of a bulky substituent and can be used to explain most of the relationships of Table 25. 

The use of steam to remove lower-boiling or lighter components from a liquid is one of the oldest methods of distillation. Sometimes called steam distillation, this technique relies on a combination of two simple effects. 

Besides the simple effects of mesophase stabilization by increased polar-apolar incompatibility and modification of mesophase morphology due to size effects, there are additional specific effects based on the lipophobicity (R[ -RH incompatibility) and rigidity of perfluorinated segments. In this respect it is important to... 

Thus, the kinetics are first order the reaction rate is proportional to the concentration of the reactant. We have seen that even complicated reaction mechanisms can lead to simple effective kinetics. 

Independent parameters with a simple effect on the resolution may be optimized sequentially, i.e. one after the other (section 5.1.1). Hence, after the selectivity has been optimized, the shortest possible column length or the highest possible flowrate may be established that will provide sufficient resolution. Adapting the length of the column is the preferred strategy, because it will lead to both faster analysis and lower pressure drops. 

Perhaps no single development has influenced today s society more than the birth control pill. This simple, effective, and inexpensive method to limit pregnancy helped bring about both the sexual revolution and women s liberation.
