In the current data article, we present detailed characteristics of voids in carbon/epoxy composite laminates as well as the original image stacks, obtained via X-ray micro-Computed Tomography (micro-CT) . Five different lay-ups are produced with altering the recommended cure cycle in order to intentionally induce voids in the material. For each lay-up, an image stack (consisting of tomographic slices) and a dataset are provided. The image slices are in 8-bit TIF format. The datasets (spreadsheets) include the volume, size parameters, shape parameters, orientation, and location of all the detected voids in the specimen. The segmentation of the images and quantification of voids are performed in VoxTex, an in-house software for processing of micro-CT results. The data is linked to a Data in Brief article "A dataset of voids’ characteristics in multidirectional carbon fiber/epoxy composite laminates, obtained using X-ray micro-computed tomography" and linked to the article "Mehdikhani et al. Detailed characterization of voids in multidirectional carbon fiber/epoxy composite laminates using X-ray micro-computed tomography. Comp Part A. in press.".

This data is associated with a submitted manuscript, where processing parameters for Ti6Al4V with and without copper addition is investigated. The two samples are both with 3% copper with different process parameters. The data format is described below and will be of interest to readers of the paper (in Additive Manufacturing journal) for visualization of pores inside the metal samples. Data is in processed format and can be opened using the free software myVGL obtainable from Volume Graphics GmbH, or the compressed image stacks can be opened, which then contains no analysis and only raw data. Voxel size is 0.015 mm isotropic. Cuboids are 10x10x4 mm and analysis region of interest is the central 6x6x2 mm of each sample. The two samples are two different process parameters with power 170 W and scan speed 0.9 m/s, and 340 W with 1.1 m/s

This research calculates the Herfindahl-Hirschman Index (HHI) and the Five Major Concentration Ratio, as well as estimates the Lerner Indicator of the Brazilian credit market, between 2000 and 2019. For this purpose, public accounting information from financial institutions was used. This information is available on the website of the Central Bank of Brazil, in the database called IF.data (https://www3.bcb.gov.br/ifdata/). The names of the accounting items used as proxies for the variables are shown in Table 2 of the paper. The concentration and competition indices include isolated financial institutions belonging to the banking segment, type b1 and b2, and non-banking institutions, type n1 and b3S. The banking segment type b1 is represented, according to the monetary authority, by commercial banks, multiples with commercial portfolios and savings banks. Multiple banks with no commercial portfolio and investment banks make up the type b2 banking segment. Individual credit unions and non-bank credit institutions are represented by b3S and n1, respectively.

Distinguishing between bull Y- and X-bearing sperm populations is advantageous for techniques with sexed bull semen. The aim of this study was to produce a single-chain fragment variable (scFv) antibody against plasma membrane epitopes on bull Y-bearing sperm to distinguish between Y- and X- sperm. Variable heavy (VH) and variable light (VL) region genes generated from a hybridoma cell secreting a specific Y-bearing sperm monoclonal antibody (mAb-1F9) were cloned and expressed. The expected sizes of the DNA bands were ~350 bp for the VH gene and ~318 bp for the VL gene. The VH and VL genes were generated and used to construct an scFv gene (~650 bp) and express the corresponding soluble scFv antibody. Compared with the parent mAb-1F9, the scFv antibodies presented a high affinity for Y-bearing sperm and low cross-reactivity with X-bearing sperm. An immunofluorescence analysis confirmed that the scFv antibodies and mAb-1F9 recognize epitopes on the Y-bearing sperm surface. The fluorescence signal was strong on the plasma membrane of Y-bearing sperm but very weak for X-bearing sperm. This study helps the application and production of engineered scFv antibodies specific to Y-bearing sperm to distinguish between Y- and X-bearing sperm populations for techniques involving sexed bull semen

Mesenchymal stem/stromal cells (MSC) have immunomodulatory properties, studied in a wide range of diseases. Validated Quality Controls must be able to confirm this activity in the context of clinical trials. This study presents the validation of a method, quantifying the ability of MSC to inhibit T cell proliferation according to the ICH Q2 standard. Peripheral blood mononuclear cells (PBMC) from a bank of ten donors, labeled with CellTrace Violet (CTV), were co-cultured with MSC at seven different ratios for seven days. Flow cytometry analysis was used to obtain the percentage of division (PD) of T cells. Two parameters were calculated: the percentage of inhibition (PI) of T cell proliferation, for each ratio X, determined using the following formula PI ratio X = (PD control – PD ratio X) / PD control, and the corresponding area under the curve (AUC). The validation of two different CTV-PBMC banks did not show any statistical difference and demonstrated stability over 509 days of storage. Analysis of repeatability and reproducibility showed a standard deviation (SD) of 6.1% and 4.6%, respectively. Robustness analysis, corresponding to the ability of a method to resist small but deliberate variations in its parameters, for PBMC, and MSC, did not present any difference. The assay was linear on the exploited range and permitted to distinguish MSC presenting different ranges of inhibition activity. This quantification method of MSC immunomodulatory activity displayed low analytical variability, sufficient robustness, and no inter-bank variability of PBMC. Therefore, it could be used for MSC manufacturing batch qualification.
