Fig. 18 in The Herpetological Collection Of Maximilian, Prince Of Wied (1782-1867), With Special Reference To Brazilian Materials

Fig. 18. Lectotype of Xenodon rabdocephalus (Wied, 1824). One of two unnumbered folio plates (left) showing ''Coluber rabdocephalus'' in the Abbildungen zur Naturgeschichte (Wied, 1827 [1822–1831] = plate 35 herein. Same specimen (right), now AMNH R-3609. This specimen suffered some decomposition in the past, with the body becoming very soft and breaking completely in two parts (arrows show place of break). Telling points of resemblance between painting and specimen are numbered: 1. Longitudinal white line on neck, terminating Y-shaped at first dorsal blotch; 2–6. Anterior and posterior pale edges of dorsal blotches, showing both resemblances and minor copying errors; asterisk (*) denotes the undivided anal plate. The resemblance between the painting and specimen is very close, allowing for the inevitable accumulated copying errors (i.e., Wied's original penand-ink watercolor was copied from life and it in turn was copied by an artist for the published plate).

Fig. 8 in The Herpetological Collection Of Maximilian, Prince Of Wied (1782-1867), With Special Reference To Brazilian Materials

Fig. 8. Agama picta Wied. Inset (A) showing orange-pigmented tongue and small dewlap. Pen-andwatercolor illustration (B) made by Prince Maximilian at Morro d'Arara in March 1816, with descriptive field identification ''Lacerta fasciata (m).'' The Abbildungen plate (see pl. 10) was prepared from this sketch. Detailed study (C) of a tail, from a different specimen than shown in the life drawing. Wied's handwritten explanation to artist (from typescript in Bosch, 1991: 238): Schwanz der Agama picta. um etwa die Vertheilung der Schuppen fu¨r den Kupferstecher genauer zu haben. In a. und b.[regenerating tail at break] sind die Schuppen aus Versehen verschieden gezeichnet, sie sind aber am ganzen Schwanze u¨berall gleich ross, klein und 4-eckig in Reihen gestellt. (''Tail of Agama picta. In order to prepare for the copperplate engraving [see pl. 10], the scales are drawn differently in a and b; along the entire tail, however, the small square scales are equally disposed in rows.'')

Fig. 4. Title page of volume 1 of Prince Maximilian's Beitra¨ge zur Naturgeschichte von Brasilien (Wied, 1825). This first of four volumes is the only one devoted to herpetology. Many new species are described in this fundamental work, which assembles information for all reptiles and amphibians collected by Wied.

Fig. 3 in The Herpetological Collection Of Maximilian, Prince Of Wied (1782-1867), With Special Reference To Brazilian Materials

Fig. 3. Title page from the third volume of Prince Maximilian's Abbildungen zur Naturgeschichte Brasiliens (Wied, 1822–1831). Illustrated taxa are listed on the volume (Liefererung) title pages, but the contained plates are unnumbered (there are 6 plates in each of 12 Liefererungen). The herpetological plates reproduced herein are arbitrarily numbered 1–56 following the organization of the present work, which reflects the order of species presentation in volume 1 of the Beitra¨ge (fig. 4). Geographic modifiers (Neuwied and Runkel) were dropped from the Wied family name in 1824. After that, ''Wied-Neuwied'' appeared only on the title pages of the Abbildungen, which had begun publication two years earlier.

Second syntype of Coluber variabilis (AMNH R-3482). Both are in the Maximilian collection, but this larger specimen seems not to have been used in the description of C. variabilis.

Measurements on reference materials for SThM measurand versus thermal conductivity calibration curve

This sheet presents the results of measurements carried out on calibration samples using the SThM technique as part of the NanoWires project. The thermal conductivity of the samples was previously characterised using a traceable technique. Measurement results are given with associated standard uncertainty. The thermal conductivity range studied was between 0.187 and 117 W.m-1.K-1.  These measurements were used to construct the thermal conductivity calibration curve for a SThM probe. The 19ENG05 NanoWires project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.

Experimental raw data sets associated with certified reference material BAM-P116 (titanium dioxide) for comparison of nitrogen and argon sorption, available in the universal adsorption information format (AIF)

These data sets serve as models for calculating the specific surface area (BET method) using gas sorption in accordance with ISO 9277. The present measurements were carried out with nitrogen at 77 Kelvin and argon at 87 Kelvin. It is recommended to use the following requirements for the molecular cross-sectional area: Nitrogen: 0.1620 nm² Argon: 0.1420 nm² Expected specific surface area for nitrogen (BET): 305 to 345 m²/g Expected specific surface area for argon (BET): 300 to 310 m²/g Titanium dioxides certified with nitrogen sorption and additionally measured with argon for research purposes were used as sample material. The resulting data sets are intended to serve as comparative data for own measurements and show the differences in sorption behaviour and evaluations between nitrogen and argon. These data are stored in the universal AIF format (adsorption information format), which allows flexible use of the data.

Dataset for FEM modelling of emission reference material (ERM) developed in the EMPIR project 20NRM04 MetrIAQ

This dataset contains the numerical data used in the project 20NRM04 MetrIAQ for the FEM model simulations on the emission reference material (ERM) with the software COMSOL 6.2. The data published here are freely accessible with a text editor. The accompanying document 'FEM data and file name explanations.pdf' contains additional information for each data file. A detailed description of the development of the FEM model can be found in the 'Guideline with recommendations on the customised design and dimensioning of the ERM, including the uncertainty of the numerical model developed for the prediction of the emission rate. The numerical model will (i) support the customised generation of the ERM (ii) simulate the transport processes inside the ERM and the compound release into test chamber air and (iii) enable the prediction of the emissions for each of the selected target VOC' (<a href="https://doi.org/10.5281/zenodo.12749007" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.12749007</a>).
