Design meaning

The shaft is a forging and may he designed as a stiff shaft or flexible shaft. A stiff shaft design means that the shaft will operate helow any of its critical speeds. Usual practice limits design operation to 60% of the first critical speed. This requires a heavier shaft than the flexible design that allows the shaft to pass through its first critical speed at 40-60% of normal and maximum operating speeds. 

In any APC, the operators must be educated and brought into it before they can use it. The control must be properly designed, meaning the model must be configured and properly tuned. The operators should be involved early and all of them should be consulted since all four shifts may be running the unit differently.

A prospective, randomized, placebo-controlled trial of paroxetine in adults with chronic post-traumatic stress disorder (PTSD) was recently conducted (Marshall etal., 2007). The subjects were New Yorkers, predominantly female (67%) and Hispanic (65.4%). Seventy subjects entered the study and after a one week placebo lead-in, 52 subjects were randomized to placebo or paroxetine for ten weeks. The subjects were treated with a flexible dosage design (mean dosage, 40.4 mg/day). Dropout rates were 32% for paroxetine and 51.9% for placebo. There were no differences in rates of adverse effects between treatment arms. Paroxetine was superior to placebo in ameliorating the primary symptoms of PTSD (56% vs. 22.2%). 

A summary of addition reactions of alkenes with 1-methylcyclopentene as the organic substrate. A bond designated means that the stereochemistry of the group is unspecified. For brevity the structure of only one enantiomer of the product is shown, even though racemic mixtures would be produced in all instances in which the product is chiral. 

In Chapter 8, we looked at some experiments that involved two parameters (factors), each at two levels. In Chapter 10, we briefly looked at a three-factor, two-level design, with attention to how it could be represented geometrically. The use of the term three factor, two level to describe the design means that each factor was present at two levels, that is, the corresponding parameters were each permitted to assume two values. 

Equation 21.3-16 may be used to convert rate constants from a mass to a particle volume basis for calculation of the Thiele modulus (eg., equation 8.5-20b). In this chapter, (—rA) without further designation means ( -rA)m. 

It is often helpful to record the results of control samples in a visible manner not only because of the greater impact of a visual display but also for the relative ease with which it is possible to forecast trends. A variety of styles of quality control charts have been suggested but the most commonly used are those known as Levey-Jennings or Shewart charts, which indicate the scatter of the individual control results about the designated mean value (Procedure 1.7). 

The US Food and Drug Administration classifies caffeine as generally recognized as safe (GRAS). This designation means that there are sufficient data and history of use to indicate that caffeine is safe to consume in the amounts commonly found in foods and beverages. The FDA allows caffeine to be added to cola drinks. 

There is another incarnation for the model in Fig. 10.1. by interpreting the frame as the base plate (with the sample) of the STM, and the mass as the tip assembly, the model describes the influence of external vibration on the relative displacement of the tip versus the sample, which is the quantity we want to reduce. A good STM design means a high resonance frequency. When the excitation frequency is much lower than the natural frequency of the STM, then the tip assembly moves closely with the frame. In fact, when f fo, Eq. (10.16) is reduced to...

As can be seen, all the elements of the extra column I are + , so that the respective effect that they evaluate is just the arithmetic mean of the responses, named in experimental design Mean effect. Although the BI P algorithm has many uses, the most rapid way to calculate effects (particularly when we consider many factors) is by means of an algorithm developed by Yates. 

Microfiltration and UF membranes can be asymmetric, with a denser side and a more open side, or uniform without macrovoids (See Figure 16.3). The open area behind the denser surface in an asymmetric design means there is less resistance to water permeating the membrane. Operating pressure can be lower and the membrane systems can be more productive. The limitation of the asymmetric design is that the material, predominately used in the hollow fiber configuration, is not as strong as the uniform cross section.

Enthalpies are measured only as differences with respect to an arbitrary standard state. Entropies, in contrast, are defined relative to an absolute zero level. In either case, the per mole designation means per mole of substance in the specified state.
