Finally, the diagnostic instrument may be administered before commencing a particular topic in order to gauge students prior rmderstanding of the associated concepts. At the same time, the use of the instrument as a formative assessment tool will enable the teacher to take appropriate measttres to challenge ary students conceptions that may become evident dttring the lesson or plan for remediation with small groups of students that experience difficulties.

Most of the cases we have looked at involve the use of multimedia for teaching and learning purposes. This section introduces two cases that use a similar format a two-tier multiple-choice diagnostic instrument with multimedia to investigate the characteristics of students conceptions about matter and particles. It also looks at the reasons for their responses to a particular problem.

In Fig. 16, the single substance approach concerning exposure and effects is depicted. There are comparable approaches and strategies for mixtures and effluents (lowest identified dilution step). There are further diagnostic instruments needed, which allow to identify the possible causes of deteriorated water quality and biota. By these instruments, it will be possible to gather further information about the effectiveness of possible measures. Examples for further diagnostic tools... 

Many laser-based droplet diagnostic techniques have evolved from the fields such as spray combustion and spray drying. Phase-Doppler particle analyzer is now recognized as the most successful and advanced diagnostic instrument for spray characterization. Other proven diagnostic techniques include laser velocimetry and...

It is a truism that no matter how sophisticated the diagnostic instrument, nothing can replace a well-conducted comprehensive clinical interview. It is essential in the assessment of pediatric PTSD that clinicians use multiple informants and take careful histories while searching for complicating comorbid conditions. No single instrument will serve all clinicians. 

Another general advantage is that optical sensing requires no physical or chemical contact with the sample. After a spectroscopic measurement is performed, the sample can be sent on to other diagnostic instruments, recycled into the body (e.g., dialysis), or archived for future analysis. Such options do not exist when chemical tests are used. The non-contact nature of optical spectroscopy also eliminates the need for reagents and reduces the number of components that need to be cleaned (for a multi-use instrument). 

To develop a new service, identify additional resources that will be required. More personnel, both for dispensing and for clinical functions, may be needed. More space for counseling, compounding, conducting classes, or placing diagnostic instruments or durable... 

The purpose of this paper is to review the use of laser induced fluorescence spectroscopy (LIFS) for studying combustion processes. The study of such processes imposes severe constraints on diagnostic instrumentation. High velocities and temperatures are common, as well as turbulent inhomogeneities, and there is a need to make space and time resolved species concentration and temperature measurements. The development of LIFS has reached the point where it is capable of making significant contributions to experimental combustion studies.
