Free chlorine is widely used in fresh-cut produce washing to minimize microbial cross-contamination, but its application can also lead the formation of harmful disinfection byproducts (DBPs). This study compared DBPs process water and washed during commercial operation. Samples shredded lettuce diced cabbages chlorinated traditional double-flume wash novel immersion-free single-pass systems wer...
In production testing, it is of importance to measure the key radiation parameters an antenna under test (AUT), e.g., main beam peak and direction, sidelobes, null depth direction in a cost-effective setup with short measurement time. As result, practical setups are often compact equipped only few probes (or probe locations). However, these system limitations would introduce errors for testing....
Objective The purpose of this study was to compare Free Beta-HCG and PAPPA levels in single normal and under IVF pregnancies 11-13w + 6d of gestational age. MaterialsAndMethods In this observational study that was performed as a cohort, 300 consecutive single IVF pregnancies and 700 single normal pregnancies were enrolled about 11-13w + 6d of gestational age and Free Beta-HCG and PAPPA was comp...
INTRODUCTION Our goal was to develop cut points for amyloid positron emission tomography (PET), tau PET, flouro-deoxyglucose (FDG) PET, and MRI cortical thickness. METHODS We examined five methods for determining cut points. RESULTS The reliable worsening method produced a cut point only for amyloid PET. The specificity, sensitivity, and accuracy of cognitively impaired versus young clinica...
