This chapter is intended for readers to quickly review topics within each content specification to consolidate information and refresh high-yield pearls in the days before taking the General Pediatric board certification exam. The exam often tests knowledge of common associations, and this chapter is meant to reinforce these frequently-tested associations. The information included in this section is mostly meant as a review of the preceding chapters, but may also be used as a stand-alone study tool. It includes memory aids and mnemonics to maximize retention.

Forty-one academic program directors completed a survey eliciting their perceptions of the Certification Board for Music Therapists (CBMT) board certification exam. Survey questions concerned the meaningfulness and utility of the exam in evaluating safe and competent practice; reasons students might fail the exam; exam preparation methods; and open-ended questions that allowed participants to express specific concerns about the exam, if they had any. On average, program directors perceived the exam to be “neither effective nor ineffective” in evaluating clinical competence, with open-ended responses suggesting the majority of these faculty had a range of concerns about the exam. After categorizing and defining these concerns, reflective comments serve to stimulate discussion about the meaningfulness and utility of the exam, as it is currently constructed.

Carbon films have been a support of choice for high resolution electron microscopy since the introduction of vacuum evaporation of carbon. The desirable qualities of carbon films and methods of producing them has been extensively reviewed. It is difficult to get a high yield of grids by many of these methods, especially if virtually all of the windows must be covered with a tightly bonded, quality film of predictable thickness. We report here a method for producing carbon foils designed to maximize these attributes: 1) coverage of virtually all grid windows, 2) freedom from holes, wrinkles or folds, 3) good adhesion between film and grid, 4) uniformity of film and low noise structure, 5) predictability of film thickness, and 6) reproducibility.Our method utilizes vacuum evaporation of carbon from a fiber onto celloidin film and grid bars, adhesion of the film complex to the grid by carbon-carbon contact, and removal of the celloidin by acetone dissolution. Materials must be of high purity, and cleanliness must be rigorously maintained.

Polyetheretherketone (PEEK) is a crystallizable thermoplastic used as composite matrix materials in application which requires high yield stress, high toughness, long term high temperature service, and resistance to solvent and radiation. There have been several reports on the crystallization behavior of neat PEEK and of CF/PEEK composite. Other reports discussed the effects of crystallization on the mechanical properties of PEEK and CF/PEEK composites. However, these reports were all concerned with the crystallization or melting processes at or close to atmospheric pressure. Thus, the effects of high pressure on the crystallization of CF/PEEK will be examined in this study.The continuous carbon fiber reinforced PEEK (CF/PEEK) laminate composite with 68 wt.% of fibers was obtained from Imperial Chemical Industry (ICI). For the high pressure experiments, HIP was used to keep these samples under 1000, 1500 or 2000 atm. Then the samples were slowly cooled from 420 °C to 60 °C in the cooling rate about 1 - 2 degree per minute to induce high pressure crystallization. After the high pressure treatment, the samples were scanned in regular DSC to study the crystallinity and the melting temperature. Following the regular polishing, etching, and gold coating of the sample surface, the scanning electron microscope (SEM) was used to image the microstructure of the crystals. Also the samples about 25mmx5mmx3mm were prepared for the 3-point bending tests.
