The significance of the tracer testing technique is widely accepted in reservoir performance analysis in hydrology as well as in hydrocarbon exploration an
Ultrasonic testing (UT) can generate ultrasonic waves penetrating deep (several meters) inside the specimen to diagnose pores, including sizes and shapes, in a non-destructive way, while it holds effectiveness only for the pores larger than 100 µm [111]. A-, B-, and C-scans are three ...
Respondents were also asked how appointments are scheduled and about the quality control procedures for analysis. Respondents from all 13 CF testing centres completed the survey. A follow up phone interview with each participant was then carried out to clarify any issues. We obtained information ...

Point-of-care testing (POCT), as a portable and user-friendly technology, can obtain accurate test results immediately at the sampling point. Nowadays, mic
Thus, we systematically measure and report test concordance between self-testers and health-care workers to account for imperfect reference standards to establish the reliability and performance of rapid diagnostic tests used for self-testing. Research in context Evidence before this study To diagnose ...
