This data set contains all measurement values and calculated results of all measurement points in the Excel and CSV files (e.g. pressure drop, volumetric flow rates, void fraction, measurement uncertainties).
In addition, the numeric results of the image processing algorithm are included in the Excel and CSV files (e.g. mean bubble diameter, maximum bubble diameter, local film flow ratio, extent of the two-phase distribution across the channel width, measurement uncertainties).
The image folders contain the pre-processed images which were the input to the digital image analysis (i.e. the aligned and cropped image section, after subtraction of the image background), and the post-processed images visualizing the output of the image analysis (i.e. detected objects are inserted as colored regions).
The measurement values and the image folders are subdivided into measurements with uniform and non-uniform gas injection and designated with the numbers of the measurement points, which are listed in the Excel and CSV files.
The original photographs made during the measurements and used for image processing are given in:

Decoding the role of tectonics, incision and lithology on drainage divide migration in the Mt. Alpi region, southern Apennines, Italy
No full textThe proclivity of river networks to progressively carve mountain surfaces and preserve markers of landscape adjustments has made analyses of fluvial systems fundamental for understanding the topographic development of orogens. However, the transient nature of uplift and erosion has posed a challenge for inferring the roles that tectonics and/or climate have played on generating topographic relief. The Mt. Alpi region in the southern Apennines has a heterogeneous distribution of elevated topography, erosionally-resistant lithology and uplift, making the area optimal for conducting topographic and river analyses to better understand the landscape development of a transient orogen. Stream length-gradient, normalized channel steepness, stream convexity and first-order channel gradient indices from 10 m digital elevation data from the region exhibit stream profile inconsistencies along the current drainage divide and a dominance of high values subparallel but inboard of the primary chain axis irrespective of known transient landscape factors, suggesting that the current river network may be in a state of transition. The location of these stream profile anomalies both near the modern drainage divide and subparallel to an isolated swath of high topography away from catchment boundaries is thought to be the topographic expression of an imminent drainage divide migration driven primarily by the ~ northeast-vergent extension of the western chain axis
Visualization of adiabatic gas-liquid flow in a cross-corrugated plate heat exchanger channel: Part 2 - Original photographs, uniform two-phase distribution
No full textThese measurement data are obtained and analyzed as part of a research project on adiabatic gas-liquid flow in a cross-corrugated plate heat exchanger channel. (See list of publications below).

The measurement data is published in 2 data sets:
Data set I: Original image data (4 parts):
- uniform gas injection, part 1: https://doi.org/10.5281/zenodo.7985771;
- uniform gas injection, part 2: https://doi.org/10.5281/zenodo.7986374;
- uniform gas injection, part 3: https://doi.org/10.5281/zenodo.7986384;
- non-uniform gas injection (part 4): https://doi.org/10.5281/zenodo.8067163
This data set contains the original photographs of the two-phase flow in the cross-corrugated channel obtained with a high-resolution camera. In addition, the corresponding experimental parameters and flow patterns (for part 1-3 only) are included in the CSV files.
For uniform and non-uniform gas injection, respectively, the images were stored in sequentially numbered folders. The numbers of the folders correspond to the numbers of the measurement points listed in the attached CSV files with the associated experimental parameters.
The image folders are grouped in ZIP archives. Each ZIP archive contains the single-phase reference images which can be used for the two-phase images to conduct background subtraction, because the lighting conditions are equal for all images in one ZIP archive.
Data set II: Measurement values and processed image data:
- https://doi.org/10.14279/depositonce-17868;
This data set contains all measurement values and calculated results of all measurement points in the Excel and CSV files (e.g. pressure drop, volumetric flow rates, void fraction, measurement uncertainties).
In addition, the results of the image processing algorithm are included in the Excel and CSV files (e.g. mean bubble diameter, maximum bubble diameter, local film flow ratio, extent of the two-phase distribution across the channel width, measurement uncertainties).
The image folders contain the pre-processed images which were the input to the digital image analysis (i.e. the aligned and cropped image section of the channel without inlet, outlet, and peripheral regions and after subtraction of the image background), and the post-processed images visualizing the output of the digital image analysis for this image (i.e. detected objects are inserted as colored regions in the image section; the meaning of colors was explained in the publications of 2022 and 2023).
In this dataset, the image folders are also subdivided into measurements with uniform and non-uniform gas injection and designated with the numbers of the measurement points, which are listed in the Excel and CSV files.
The two datasets are the supplementary research data for the following publications:

Moving towards a new view of diagnostic work : some implications
No full textThe diverse studies of diagnostic work in this book give shape to a new view of diagnostic work. They highlight just how much more than individual cognitive capability is needed, the close relationship between analysis and intervention, the often implicit nature of diagnosis, and the fact that there are several degrees or levels of diagnostic work. Different knowledges, motivations, skills and forms of expertise are mobilised in often collaborative and embodied encounters between people and objects. Matter and matters are made to speak in many ways through social, material and embodied practices. We would like to argue that this ʼnew view’ of diagnostic work does not just ‘explain’ diagnosis in a more precise and sensitive manner. Indeed, in light of the rich descriptions in this book, the attempt to summarise the new view above exposes explanation as an unsatisfactorily abstract endeavour. The studies in this book, importantly, provide much more than explanation. They exhibit the specificities of diagnostic practices in different settings, some important intended and unintended consequences, moral and political implications, as well as opportunities for change

Low-angle normal faulting and focused exhumation associated with Late Pliocene change in tectonic style in the southern Apennines (Italy)
No full textIn the southern Apennines, lowerature thermochronometry data indicate that exhumation of previous tectonically buried sedimentary units started at around 10Ma and took placemostly during the last 6Ma. Relatively high exhumation rates are obtained from apatite fission track (AFT) and (U-Th)/He (AHe) analysis, pointing to a substantial contribution of tectonic processes to rock exhumation besides erosion. Exhumation rates derived fromnew apatite (U-Th)/He data (AHe) for the last 3Ma are generally lower than rates determined by AFT data and almost in line with erosion rates inferred from cosmogenic nuclides and sediment yield, thus suggesting that tectonic exhumation was dominant during the older exhumation stages of this region. However, younger cooling ages in the Monte Alpi area from both AFT and AHe analyses point out focused exhumation during the last 3Ma. Structural and morphotectonic analyses indicate that fast exhumation occurred specifically in this area-where the Apulian Platfor..
