There are two main types of clinical trial design, parallel and cross-over. In a parallel study, subjects are assigned to one of two or more treatments, e.g. active and placebo, and proceed through the trial concurrently. In a cross-over design, subjects act as their own controls, undergoing two or more treatments in sequence (see Fig. 12.1). 

Unless otherwise noted, all of the adult and children s behavioral scales are given once pretreatment and at least once post-treatment (depending on the trial design, subject drug pharmacokinetics, and length of the trials). Investigators may schedule additional evaluations with these tests, but this is usually not done at less than weekly or biweekly intervals. Many tests provide data on both a total score and... 

Randomized Crossover Design Subjects are divided into placebo and active groups. After some time these two groups crossover the initial placebo group now becoming the active group and vice versa. There may be a washout period before the crossover to enable the effect of the placebo and active to wash out. This method requires a smaller number of subjects and is useful in cases for studying rare or more stable illnesses.

This has become the most commonly used criterion in the literature on supersaturated designs. Sometimes these two criteria are combined, for example, by choosing a supersaturated design that minimizes E(s2) subject to some upper bound on maXi j si j. Cheng and Tang (2001) gave upper bounds on the number of factors that could be included in a supersaturated design subject to max, x,j1 < c, where c is a constant. 

Protocol The study s rationale, design, subject selection criteria, concomitant medications, visit schedules, and observations and measurements to be made to fulfill the study s objectives (labs, assessments, tests) are discussed with the entire staff conducting the study. 

When designing protocols to measure deposition, a number of clinical factors need to be considered and incorporated into the study design subjects age, sex, smoking history, and current drug regimens, presence of a viral infection, severity of disease, stability of pulmonary function, and other outcome measures that could affect the inhalation of the radioaerosol, the measurement of deposition, and the results. Some of these also apply when using healthy volunteers as subjects for deposition studies. For example, we allow a 4- to 6-week recovery period between repeat studies for subjects who have suffered an exacerbation of their asthma or developed a chest cold or infection after enrollment. 

In a concentration-response design, subjects receive either a fixed dose (or dose range) of a medicine and their plasma concentrations are... 

In this work, the authors have attempted to outline the scope of topical problems existing in the modeling of oxidation processes in gas chemistry. We consider each section in this work as a formulation of the corresponding problem, but not as its solution, and, accordingly, the entire paper as an invitation to a broad discussion on the designated subject. Besides, we believe that the principles formulated below could be utilized in developing consistent kinetic models of the open type. The latter means that such models can be further built on as new reliable kinetic information becomes available. 

The molding compound flowing from the nozzle enters the mold and is distributed into the cavities. This is the task of the sprue- and numer system (see Figure 4-1). It consists of several sections, that may differ in design, subject to requirement. As the melt leaves the nozzle, it passes through the sprue bush and into the runner, which connects to the gates of the cavities. 

I have not located a resource that sets forth in concept form the principles to be applied in designing for safety. Standards, regulations, specifications, design handbooks, and checklists that establish the minimums for specific design subjects are plentiful, and they are very important. But, a concept of designing for safety must go far beyond the application of the minimums set forth in standards and guidelines.
