These two control procedures involved comparable sensory-motor and motivational variables to those of the sustained attention task, but did not explicitly tax attentional processes.
We were able to direct our attention to possible environmental sources, such as improving the compliance with infection control procedures involved in central venous catheter care rather than interventions to prevent person to person spread, such as single room isolation.
The methods used to collect and perform laboratory analyses of perchlorate, iodine, T4, TSH, cotinine, and thiocyanate, and the quality control procedures involved in NHANES 2001 2002, are described in detail elsewhere (National Center for Health Statistics 2002).
Additional quality control procedures involved review of data forms at the central site and troubleshooting problems in administration by the study coordinator at the central site and research assistants at different sites.
The quality control procedure involved multiple automatic checking of internal consistency and biennial audits.
The control procedure involved one and a half hours of exploring the early memory and the recurrent image.
However, we did not obtain outbreak control after implementing hygiene procedures involving only NICU staff.
The 268 surgical control women were admitted for procedures involving the gallbladder (n = 106), removal of lipomas (n = 16), abdominal hernias (n = 22), osteoarthritis (n = 21) and other disorders unrelated to breast disease.
Quality control procedures, which involved testing SmCTF-RDTs with schistosome-positive reference sera and European negative controls, were performed prior to distribution of SmCTF-RDTs.
All such methods have well-standardized quality assurance/quality control procedures that involve the regular use of calibration standards and participation in proficiency protocols.
