Diagnosis physical characterization

Primary care physicians are critical to the successful identification of GAD. Characterized by often-vague physical complaints, GAD must be distinguished from medical illnesses and other psychiatric disorders, though the high rate of comorbidity requires that a thorough evaluation for GAD be completed even when another disorder has been identified. GAD warrants particular consideration for those patients with nonspecific physical complaints who nevertheless have an urgent need for relief that has resulted in repeated office visits. The differential diagnosis for GAD includes other anxiety disorders, depression, and a variety of medical conditions and substance-induced syndromes. 

Toxidrome is a term which is used to describe a constellation of signs and symptoms, which when taken collectively, may characterize the poison in question. This is particularly important if patient has altered sensorium, and there is no reliable informant for a medical history. It may be important to review physical features and the differential diagnosis of the... 

With the development of fuel cell technology, many different investigative tools, including electrochemical and physical/chemical methods, have become available that elucidate CL degradation. These methods provide valuable information on morphology (surface or cross-section of the CL, size distribution of the catalyst particles), elemental content and distribution, atomic structure of the local particles inside the CL, and electrochemical characteristics of the CL in fuel cell systems. At present, characterization of PEM fuel cell electrodes mainly concentrates on morphological characteristics (surface and microstructure), electrochemical diagnosis, and composition analysis.
