Tensile performance data of 3D printed MMJ composite samples

This repository contains force-displacement data of ASTM Type V tensile samples created using MMJ 3D printing. The samples are composites of two MMJ printing materials, one rigid (Vero) and the other soft (Agilus30). The composite geometries include solid materials, blends, sandwiched three-layer samples, and multi-layer samples. All samples were printed using a Stratasys J750 printer with the longest dimension oriented in the "X" direction. A TestResources Nano fatigue testing machine and testing rate of 10mm/min was used for all tensile tests. The "Solid_dogbone_typeV.stl" sample was used to create the solid material samples and the blends.- The zip file "Raw_data_all.zip" contains the machine force-displacement output for all samples.- The "Supplementary_materials.docx" file contains information matching the sample prefixes from the zip file data to the materials used to create the sample.- The "3D_models_stl.zip" file contains mesh files for each sample type.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Comparison of High Frequency and Low Frequency Tympanometry Findings in Normal Neonates

Abstract Background: Tympanometry is one of the most important audiological tests for the assessment of neonatal hearing screening programs. This test is usually done using a 226 Hertz probe tone; however, in infants less than 6 months of age, using this probe tone frequency is not reliable due to the different characteristics of the middle ear compared to adults. The purpose of this study was to assess the obtained tympanometric data in neonates 1 to 14 days with normal hearing using 226, 678, 800 and 1000 Hertz frequency probes tones. Materials and Methods: In this cross-sectional study, 30 neonates aged 1 to 14 days who were diagnosed as normal in hearing aspect with using otoacoustic emissions test, were assessed by tympanometry. Tympanometric tests were performed using 226, 678, 800 and 1000 Hertz frequency probe tones for both ears. For data analysis, the T-paired method has been used. Results: With using 226 Hertz frequency probe tone, incidence of unusual double peak tympanograms was observed in 65% of cases, which with increasing frequency of the probe tone, this percentage was decreased. There was also a statistically significant difference between the static admittance peak compensated in two 226 and 1000 Hertz frequency probes tones. Conclusion: In neonates with normal hearing and without any risk factors for hearing loss, the 1000-Hertz Tympanogram shows a better middle ear status than the 226-Hertz tympanogram
