A year in which Democrats were running against a party freighted by the most unpopular president in history -- and amid an economic collapse -- is probably not the best laboratory for measuring the success of his experiment.
The samples were analyzed in the laboratory for measuring the nitrate concentrations in groundwater.
Groundwater samples were collected from 30 locations in the study area and analyzed in laboratory for measuring the nitrate concentrations.
Collected water samples were analyzed in the laboratory for measuring concentrations of nitrate, ammonia, phosphate, and sulfate.
First-morning urine samples were collected and delivered to the local Center for Disease Control and Prevention laboratory for measuring UIC.
A laboratory for measuring physical condition with cycle ergometers, treadmill ergometers, weights, dumbbells, dynamometers, pulse oximeters, electrocardiographs, anthropometric measuring instruments, blood gas analysers, and heart rate monitors, as well as defibrillators and systems for data management, among other equipment.
Each health centre has a well-established infrastructure including: A laboratory for measuring physical condition with cycle ergometers, treadmill ergometers, weights, dumbbells, dynamometers, pulse oximeters, electrocardiographs, anthropometric measuring instruments, blood gas analysers, and heart rate monitors, as well as defibrillators and systems for data management, among other equipment.
Spot urine samples were collected and delivered to the local Center for Disease Control and Prevention laboratory for measuring UIC, which was determined by the modified acid-digestion method (method for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry, WS/T 107-2006, Ministry of Health People's Republic of China).
After collection, specimen samples were refrigerated or maintained on ice in a cooler before being collected by study personnel daily, and then were transported to the University of Washington research laboratory for measuring the total void volume and specific gravity for each of the urine samples.
