Magneto-optic (MO) imaging produces images of magnetic flux leakage from surface and sub-surface defects. The presence of domain boundaries in the MO sensor produces a characteristic artefact in the images that renders detection of cracks difficult. This paper presents two different approaches for the removal of domain boundaries in MO images. The first approach uses static methods that rely on...

In this study, the performance (particle removal efficiency and breathing resistance) of several commercially available face masks (KF80-certified electrostatic nanofiber filter masks, an uncertified mask) was evaluated, along with their structure composition. Also, effects relative humidity (RH) incoming air, water alcohol exposure, reuse, on were examined. Monodisperse polydisperse sodium chl...

BACKGROUND Few studies have evaluated interventions to decrease a woman's anxiety after she receives an abnormal mammogram (i.e., one with a recommendation for follow-up). We performed a controlled trial to compare the effects of both an immediate reading of mammograms (i.e., a radiology intervention) and of an educational intervention that taught skills to cope with anxiety on the psychologica...

Morpholino oligonucleotides (MO) can induce gene silencing by binding to a target mRNA and inhibiting its translation, and this technique has been especially successful in studies of embryonic development in various vertebrates. But in mice MO-induced downregulation of target genes has not been widely reported. In this study, we examined whether MO delivery using ethoxylated polyethylenimine (E...

Great uncertainty exists around indoor biomass burning exposure-disease relationships due to lack of detailed exposure data in large health outcome studies. Passive nephelometers can be used to estimate high particulate matter (PM) concentrations during cooking in low resource environments. Since passive nephelometers do not have a collection filter they are not subject to sampler overload. Nep...

In present work, we report synthesis of molybdenum (Mo) thin films by direct current (DC)-magnetron sputtering method. The structural, optical, morphological, and electrical properties were investigated as a function of target-to-substrate distance. From the results, it is evi d ent that with increase in target-to-substrate distance the thickness of films decreases while its sheet resistance an...

Antisense morpholino oligomers (MOs) have been indispensable tools for developmental biologists to transiently knock down (KD) genes rather than to knock them out (KO). Here we report on the implications of genetic KO versus MO-mediated KD of the mesoderm-specifying Brachyury paralogs in the frog Xenopus tropicalis. While both KO and KD embryos fail to activate the same core gene regulatory net...
