However, the need of ambient temperature for the reaction to proceed will not be fulfilled since hydrothermal systems by definition are characterized by elevated temperatures.
One possible reason behind this is the lack of tools to support companies while dealing with services that by definition are characterized by high level of intangibility and perishability.
By definition, COPD is characterized by continued airflow limitation that is progressive and is associated with an increasing chronic inflammatory response in the airways and the lung to hazardous particles or gases, including CS. COPD has a higher risk of mortality than other diseases such as angina, respiratory infection, fractures, myocardial infarction, and osteoporosis [ 9].
According to the Rome III definition, FD is characterized by bothersome postprandial fullness, early satiation, epigastric pain and burning for the past 3 months with at least 1 day per week or more with onset of more than 6 months prior to diagnosis and no evidence of structural disease at endoscopy [ 11].
(By definition, mercurial behavior is characterized by rapid and unpredictable changes of mood).
Although the definitions vary, OIC is characterized by infrequent and incomplete bowel movements (BMs), straining, and hard, dry stool consistency; additional gastrointestinal symptoms include abdominal discomfort, pain, and bloating (5).
According to the modern definition, a geomagnetic storm is characterized by a main phase during which the horizontal component of the Earth's low-latitude magnetic fields are significantly depressed over a time span of one to a few hours followed by its recovery, which may extend over several days (Rostoker et al. 1997).
By definition, the superparamagnetic state is characterized by two features: the lack of remanence and the temperature dependence of magnetization curves (magnetization curves normalized by temperature superimpose, i.e., a plot of M/ T vs H/ T).
Recently, a cluster of cardiovascular disorders have been unified under the definition of "metabolic syndrome," which is characterized by a high cardiovascular risk (Haffner 2007).
