Figure Lengend Snippet: FIGURE 2 | Location of 10-spectrometer upward looking FLYSPEC array downwind of the summit of K¯ılauea (F0–F9), with station and instrument inset, ground-based anemometers and UV camera used for approximating plume speed (blue), traverse route on Crater Rim Drive (red), 2014–2017 location of Hawaiian Volcano Observatory and Overlook vent (yellow). Dominant trade wind direction indicated by arrow in upper left.

Article Snippet: For one, we used a mobile DOAS instrument consisting of an Ocean Optics spectrometer (either USB2000+ or SD2000) connected to an upward-looking telescope with a fused silica fiber optic cable.

Figure Lengend Snippet: FIGURE 4 | Plume speed calculated from peak correlation using two along-axis FLYSPEC instruments versus 3-m agl wind speed measured with an ultrasonic anemometer (station SDH; Figure 2) for June–September 2017. Data is filtered to include only plume speeds used to calculate emission rates (see section “Spectrometer Array”).

Figure Lengend Snippet: FIGURE 7 | (A) SO2 column amounts during helicopter traverses measured with an upward-looking DOAS between 09:26 and 09:51 HST on 29 June 2017. The tracks are 3∼km downwind of the vent and the warmer colors (yellow, orange, red) indicate higher SO2 column amounts. Note that the plume center is located between array stations F7 and F9, likely contributing to underestimated values by the array as compared to the helicopter traverse.Image ©2018 DigitalGlobe. ©2018 Google. (B) Time series of 10-s SO2 emission rates measured by the spectrometer array (black dots) between 09:00 and 10:00 HST on 29 June 2017. Red bars indicate the range of plausible SO2 emission rates derived from upward-looking DOAS traverses on a helicopter at the location of the array (first five measurements) and ∼3 km farther downwind (last 3 measurements) using the various spectral retrieval methods described in section “Calculating SO2 Column Densities From UV-Spectral Data.” The plotted times for the 3 downwind measurements were adjusted to account for plume travel time.

Article Title: Sexual dichroism and pigment localization in the wing scales of Pieris rapae butterflies

doi: 10.1098/rspb.2006.3708

Figure Lengend Snippet: Reflectance spectra of the wings of Pieris rapae rapae measured with a reflection probe connected to a fibre optic spectrometer from restricted areas (indicated by a number) of the dorsal forewing (1), dorsal hindwing (2), ventral forewing (3) and ventral hindwing (4) of (a) a male and (b) a female. The inset in (a) shows the dorsal side of a male P. r. rapae and the inset in (b) presents the ventral side of a female. The reflectance spectrum of the ventral hindwing of the male is lower than the other spectra in the blue–green wavelength range, resulting in a yellowish colour. The female wings are generally slightly yellower than those of the male. The indicated wing locations were the same for both male and female. Scale bars, 1 cm.

Article Snippet: Three males and three females of each subspecies were investigated. (b) Spectrophotometry Reflectance spectra of intact wings were measured with a reflection probe connected to a fibre optic spectrometer (SD2000, Avantes, Eerbeek, The Netherlands), using a deuterium/halogen light source.

Article Title: Molecular Identification of Carnosine N-Methyltransferase as Chicken Histamine N-Methyltransferase-Like Protein (HNMT-Like)

doi: 10.1371/journal.pone.0064805

Figure Lengend Snippet: The enzyme was purified by chromatography on DEAE-Sepharose (A), Q-Sepharose (not shown), Superdex 200 (B), and Superdex 75 (C) as described in “ ” section. Fractions were tested for carnosine N-methyltransferase activity. Protein concentration was determined in the most active fractions with the Bradford assay. The indicated fractions eluted from the Superdex 75 column were analyzed by SDS-PAGE and the gel was stained with Coomassie Blue. The indicated bands were cut out of the gel, submitted to trypsin digestion and analyzed by tandem mass spectrometry.

Article Snippet: DEAE-Sepharose, Q-Sepharose, Superdex 200, Superdex 75 resins, 1 ml HisTrap HP (Ni 2 + form) and PD-10 columns were obtained from GE Healthcare Bio-Sciences (Uppsala, Sweden).
