Accurate temperature measurements provided by temperature probes are necessary for process control and process validation. A temperature probe consists of a temperature-sensing element protected by a cylindrical shell. The probe can be installed within a plug that thermally insulates it from the vessel or piping wall as shown, or directly in the wall. Differences between the actual fluid temperature and the indicated probe temperature can occur when heat is conducted along the probe and out to the environment or to the vessel or piping wall. Probes with larger length-to-diameter ratios experience less stem conduction than probes with smaller L/D ratios. For a probe installed in an insulated plug where heat loss to the environment is the cause of the temperature error insulating the external probe components from the environment helps to reduce error. Special probes with nonmetallic inserts can greatly reduce the effective thermal conductivity of the probe virtually eliminating the error. Temperature probes without thermowells are more slender than those with thermowells, so they experience less stem conduction.

A large body of research has indicated that rational emotive behavioral therapy (REBT) is highly effective for treating many chief complaints. Because of the neurological and developmental limitations of young children, a counselor is required to use concrete and stimulating ways to treat young children. By incorporating art, color, and texture to teaching a child client the concept that thoughts cause feelings, a counselor can introduce an evidence-based framework to aid the young client. © Taylor & Francis Group, LLC.

Psychostimulants (methylphenidate and amphetamine salt) are the pharmacologic treatment of choice for children with attention-deficit/ hyperactivity disorder. However, psychostimulants have been linked to a variety of vascular problems, including peripheral vasculopathy. This article describes four boys with attention-deficit/hyperactivity disorder who developed vasculopathy during treatment with psychostimulants. © Springer Science+Business Media, LLC 2010.
