Objective: The aim of this in vitro study was to compare the biaxial flexural strengths of permanent restorative materials produced by additive manufacturing and milling after thermal aging. Material and methods: For this study, three study groups were formed by producing disc-shaped specimens with a 3D printer (Form3, Formlabs) using permanent crown material (Permanent Crown, Somerville, MA) and two different resin-containing materials (Brilliant Crios,Coltene/ Whaledent; Cerasmart, GC Europe) by the milling method (n=10). The entire production process was carried out in accordance with the m

Abstract This study was to determine the significance of factors considered for the measurement accuracy of personal dosimeter in dosimetry services such as dosimetry service, irradiation category, years of use and readout frequency. The investigation included management information questionnaire, on-site visit and blind test. The blind test with random selected personal badge was used in inter-comparison of eight dosimetry services, and the test results followed ANSI/HPS N13.11 criteria. This study also analyzed the measurement deviations if they felt in the criteria of ICRP 75 or not. One-wa

In drosophilids, competition and coexistence can impact survivorship, growth, and reproductive output. Here, we evaluated direct competition between two co-occurring fruit flies, the spotted-wing drosophila Drosophila suzukii and the African fig fly Zaprionus indianus, comparing results from field collections with laboratory experiments. Field collections were conducted to evaluate co-occurrence between species. In the laboratory, different densities of eggs of each species were provided an artificial diet, and intra- and interspecific densities were evaluated regarding biological traits such
