Translaminar Fracture in a Mini-Protruded Compact Tension Specimen: A Dataset of Micro-Scale Tomograms of a Thin-Ply Carbon Fibre-Epoxy Composite acquired via Synchrotron Radiation Computed Tomography During In-Situ Loading
<p>In this study, we developed a scaled-down “mini-protruded compact tension specimen” to facilitate in-situ tensile testing coupled with synchrotron radiation computed tomography (SRCT). This innovative design provides valuable insights into in-situ translaminar damage mechanisms, significantly enhancing the accuracy of data used in finite element models.</p> <p>The specimen is made of HS40 carbon fibres and ThinPreg<sup>TM </sup>736LT epoxy resin, with the layup of [90<sub>2</sub>/0/90<sub>2</sub>/0/90<sub>2</sub>/0/90<sub>2</sub>]. The translaminar fracture experiments were conducted under continuous loading and scanning using ultra-fast SRCT at the Swiss Light Source (SLS) TOMCAT beamline (Paul Scherrer Institut in Villigen, Switzerland). A polychromatic beam with an energy of 24 keV was used. The achieved voxel size was 800 <em>nm</em>, and 1000 projections per scan and 2 <em>ms</em> exposure time were acquired per scan. The GigaFRoST camera served as the detector. The scans were reconstructed into 3D volumes using the SLS’s in-house absorption-based algorithm (Gridrec) for critical loading steps during a test—both before and after a load drop (detailed in the accompanying Excel file). The tensile loading was exerted on the specimen at a rate of 0.2 <em>mm/min</em> until failure during scanning with the Deben CT500.</p>

Posteromedial reversed L-shaped approach for posterior column tibial plateau fractures
<blockquote>Posterior column tibial plateau fractures are best treated via a posterior approach. Various approaches have been described for reaching the posterior aspect of the tibia plateau: posterolateral, direct posterior, and posteromedial. The posteromedial reversed L-shaped approach however, has been proven to be very elegant and straightforward, and offers an excellent exposure of the whole posterior wall. The WAVE proximal posterior tibia plate fits in this approach with its identical reversed L-shaped configuration. The combined approach and implant are referred to as the reversed L-shaped concept. Here we demonstrate the posteromedial reversed L-shaped approach for a two-column tibial plateau fracture using the WAVE proximal posterior tibia plate in a step-by-step-fashion.</blockquote>

Interlocked thin-ply reinforcements for improved fracture toughness and compression after impact
<p>This dataset contains data showing the effect of interlocked thin-ply reinforcement units on the fracture toughness and compression after impact strength of CFRP laminates. For both the fracture toughness and the CAI experiments, tests were conducted on non-reinforced baseline specimens, as well as reinforced specimens. These experiments were conducted to test a reinforcement concept, consisting of creating reinforcement units by interlocking two thin-ply prepreg layers with a tab-and-slit geometry. These reinforcement units are then inserted between the plies of a regular composite lay-up.</p> <p>This reinforcement concept was first presented at the 18th European Conference on Composite Materials (2018, Athens, Greece). More information on the concept can be found at: http://wwwf.imperial.ac.uk/aeronautics/research/pinholab/interlock-tabs/. </p> <p>The fracture toughness section of this dataset contains both mode I and mode II data. The mode I data was acquired using DCB specimens, and the mode II data was obtained from 4-point end notch flexure tests. Force, displacement, crack length, and strain energy release rate during the test are provided for all specimens.</p> <p>The CAI section of the dataset contains post-impact C-scans, as well as force, displacement, and strain gauge data from the subsequent compression tests.</p> <p><br> </p>

Evaluation of Selected Artificial Aging Protocols for Dental Composites Including Fatigue and Fracture Tests
<p>This research was funded by the National Science Centre, Poland [grant number: UMO-2020/37/N/ST5/00191, 2021].</p> <p>Datasets was basis for publication entitled: </p> <p>Evaluation of Selected Artificial Aging Protocols for Dental Composites Including Fatigue and Fracture Tests, published at Applied Sciences in 2024. </p> <p>The publication is a summary of the second step of the project, that aims standardizing an artificial aging protocol for dental composites. Until now, there has been no effort to create a standard protocol for evaluating the clinical performance of dental composites in a practical and efficient manner. Dental materials are not required to undergo studies that verify their durability over their expected lifespan before they are released to the market. Implementing a standardized aging process is essential to enhance the dental resin composite's ability to withstand oral conditions. Research in this area has been supported by the Preludium grant from the National Science Center in Poland.</p> <p>Three materials were tested to compare the degradation of resin from that of the filler and resin–filler interface. The first material (Resin F) was unfilled resin. The second and third materials were composites based on a similar resin matrix to Resin F but with differentiated fillers content. On the basis of the obtained data (https://zenodo.org/records/6583563), three protocols were selected for the second part of the project (standardization of artificial aging protocol for dental composites). The influence of three selected aging protocol on the material properties of the samples was determined based on flexural strength (FS), diametral tensile strength (DTS), Vickers hardness (HV) and microstructure evaluation. Additionally, fracture toughness (FT) and flexural fatigue limit (FFL) were determined. The proposed complex aging protocols should simulate prolonged, possibly several to even a dozen or more years of material usage in the oral cavity, thereby furnishing valuable insights into its prospective clinical performance in vitro. </p> <p>Authors hope to determine an artificial aging method for evaluating the clinical performance of dental composites. Our publication is first attempt to determine standard aging protocol for dental composites.</p>
Lumbar Spine Vertebral Compression Fractures (VCFs) Dataset: MRI T1-Weighted Images for Benign and Malignant Classification
<p>This dataset was prepared for the study of classification of benign vertebral compression fractures (VCFs) secondary to osteoporosis and malignant VCFs secondary to neoplastic infiltration. The original study in which it was used aimed to assist in differentiating these conditions using three-dimensional radiomic techniques and artificial neural networks.</p> <p>This dataset was assembled from sagittal T1-weighted magnetic resonance imaging (MRI) scans of the lumbar spine obtained from consecutive patients diagnosed with benign or malignant VCFs at the University Hospital of the Ribeirão Preto Medical School (HCFMRP) between the years 2010 and 2019. The images were acquired using the Philips Achieva 1.5 T and 3 T MRI systems and were stored in the DICOM (Digital Imaging and Communications in Medicine) format.</p> <p>The compilation of the dataset followed a rigorous selection and filtering process. From the initial set of cases of vertebral fractures in the lumbar region, patients who had received prior treatment (such as chemotherapy, radiotherapy, or surgery), those with fractures of traumatic etiology, old fractures, patients under 18 years old, and cases of malignant fractures without biopsy confirmation were excluded. With these exclusions, the final set consists of 91 patients (36 men and 55 women, with a mean age of 64.24 ± 11.75 years), of which 47 have benign VCFs and 44 have malignant VCFs.</p> <p>For the segmentation of fractured vertebrae, the images were pre-processed by normalizing the intensity to 256 gray levels (0 to 255), and histogram equalization was applied to improve contrast. The vertebrae were semi-automatically segmented using the 3D Slicer software. Each segmentation was saved in the "nrrd" format, native to 3D Slicer. The entire segmentation process, as well as the definition and application of exclusion criteria, were supervised by a senior radiologist with 20 years of experience in musculoskeletal radiology.</p> <p>The structure of this dataset includes, in addition to the DICOM exams, a directory containing the requantized images to 256 gray levels in the "nrrd" format and another with the segmentation files in the "seg.nrrd" format. A spreadsheet with detailed information about each patient's class, sex, age, and which vertebral bodies were segmented is also available. All DICOM files in this dataset have been anonymized to ensure patient privacy.</p> <p>This dataset was structured to provide a robust basis for the training and validation of machine learning models focused on the classification of vertebral compression fractures. It was designed to aid in the massive three-dimensional extraction of radiomic features, enabling the search for radiomic signatures capable of assisting radiologists in the accurate characterization of these fractures.</p> <p>For more information on how the dataset was created and used, please refer to the original article: <a href="https://link.springer.com/article/10.1007/s10278-023-00847-4" target="_blank" rel="noopener"><em>Chiari-Correia NS, Nogueira-Barbosa MH, Chiari-Correia RD, Azevedo-Marques PM.
