    How do we learn languages? Literature on the topic is full of theories and hypotheses (Chomsky, 1965; Halliday, 1973; Skinner, 1975; Hatch, 1978; Schuman, 1978; Krashen, 1981; Lyons, 1981) that highlight the various aspects of the issue and try to identify the elements of the process. Unfortunately, however, we still do not know in full detail how languages are learned/acquired. Several applied linguists interested in second-language acquisition stress that we learn a foreign language when we use it (Widdowson, 1978; Brumfit, 1980; Savignon, 1983), when it is meaningful (Rivers, 1983; Ellis, 1986), when it satisfies our needs (Mumby, 1978; Oxford, 1990), when it allows us to interact (Leontiev, 1981; Bakthin, 1982; Brown, 1987), to solve problems (Finocchiaro and Brumfit, 1983, Chamot et al., 1987), to manipulate concepts and words "Hansen and Krening, 1982; Omaggio, 1986), and/or when our affective barriers are sufficiently low (Schuman, 1980; Krashen, 1981). Often, however, these conditions can neither be favoured nor guaranteed at university level. Classes may be too large, teachers may be too busy and students may live far away or have conflicting time schedules. Such a situation calls for a change in both teaching and learning approaches: a change that may gradually entail independence from tutors, favour self-access and lead students toward autonomy in learning

The following Creative Commons license applies to the research data (images and measurement values): CC-BY 4.0 Author: Susanne Buscher 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.

    These 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 following Creative Commons license applies to the research data (images and measurement values) uploaded to the online repositories: CC-BY 4.0 Author: Susanne Buscher 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: - S.

    The efficacy of a combination of milbemycin oxime and praziquantel in preventing the establishment of experimentally induced heartworm (Dirofilaria immitis) infection was investigated in a study involving 24 young domestic short-hair cats. The animals were inoculated with 50 infective larvae on day 0. Subsequently they were divided into two groups of 12 animals each. The animals in group 1 were treated once with medicated tablets containing 4 mg milbemycin (minimum dose 2 mg/kg body weight) and 10 mg praziquantel (MILBEMAX(R)) on day 30 after infection. Cats in group 2 received placebo tablets on the same day. On day 183 post-infection a blood sample was taken from each animal before euthanasia and necropsy. The blood samples were tested for the presence of microfilariae and the necropsied animals were examined for the presence of adult worms. Microfilariae were not found in any of the investigated cats. No heartworms were found in the animals in group 1 (treated with medicated tablets). Out of the 12 placebo-treated cats 1 was heartworm-free, whereas all the others were found to be infected with 1-3 adult heartworms

    The Mw 5, 2013 Matese earthquake epicentral area (southern Italy). New data on the earthquake ground effects and active tectonics framework

    No full text
    The Matese ridge area (southern Apennines) is located in one of the most seismically active sectors in Italy. On 29th December 2013, it was affected by a Mw=5 earthquake. In the Matese area, we are carrying out a study aimed at identifying and characterizing active faults at the surface through the integration of geomorphological, structural and soil gas data, and at outlining the ground effects of the 2013 earthquake. The new data indicate that the active fault system is more complex than previously assessed. In addition, our estimation of the epicentral intensity of the 2013 earthquake according to the ESI scale (Michetti et al., 2007) indicates that earthquakes of relatively low energy may trigger noticeable environmental hazards
