Results are reported on dual-band detectors based on a GaN/AlGaN structure operating in both the ultraviolet–midinfrared (UV– MIR) and ultraviolet–farinfrared (UV–FIR) regions. The UV detection is due to an interband process, while the MIR/FIR detection is from free carrier absorption in the emitter/contact followed by internal photoemission over the barrier at the GaN/AlGaN interface. The UV d...
BACKGROUND Detection of amyloid can be done by several techniques either histochemical or immunohistochemical. Among them, one of the less mentioned in texts of reference and in reports on amyloidosis, is the examination with ultraviolet light of the stain of Congo red. We intend to examine cases of amyloidosis stained with Congo red with ultraviolet light and to see if such method offers advan...
apigenin is best known as an irreversible inhibitor of monoamine oxidase (mao), an intracellular enzyme associated with the outer membrane of mitochondria. the purpose of this study is to establish a reliable and quick method for the assignment of apigenin in cosmos bipinnatus, apium graveolens and petroselinum crispum by high performance liquid chromatography with ultraviolet detection (hplc-u...
We present a paternity testing case in which a double incompatibility was found for two short tandem repeat (STR) markers, human fibrinogen alpha (FGA) and Penta E. Analysis of the trio (mother, father, and daughter) included the amplification with a battery of 15 autosomal short tandem repeats (STR) by using a commercially available PowerPlex 16 System kit, and the detection with an ultraviole...
Recently a new detection method, based upon aerosol charging (the charged aerosol detector (CAD)) has been introduced as an alternative to evaporative light-scattering detector (ELSD), chemiluminescent nitrogen detector and refractive index detector for detection of non-ultraviolet and weakly ultraviolet active compounds and for UV-absorbing compounds in the absence of standards. The content of...
