A new experiment is described to detect a permanent electric dipole moment of the proton with sensitivity $10^{-29}e\cdot$cm by using polarized "magic" momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant are discussed and techniques address them presented. The measurement sensitive physics beyond Standard Model at scale 3000~TeV.
The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has searched for axions in 19.74 $\mu$eV to 22.47 mass range. detection concept follows Sikivie haloscope principle, where Dark Matter convert into photons within a resonator immersed magnetic field. is an array of four individual rectangular cavities inserted strong phase-matched maximize sensitivity. Here we report on data acquired 4124 h from 2019 2021. Each cavity equipped with fast frequency tuning mechanism...
Purpose Polyetheretherketone (PEEK) is used to manufacture biomedical implants because it has a high strength-to-weight ratio and strength biocompatible. However, the use of fused deposition modeling print PEEK results in low crystallinity. This study aims Taguchi method optimize printing factors obtain highest tensile printed object. The annealing effect on object crystallinity are also investigated. Design/methodology/approach determines including speed, layer thickness, temperature...
Residual monomer contents and surface hardness are important factors in determining the serviceability of provisional restorations. The intent this study was to systemically evaluate effects curing conditions on polymethyl methacrylate (PMMA) resins which utilize a free‐radical polymerization reaction. Combinations three temperature, pressure, environment (water/air) were adjusted during fabrication autopolymerized specimen disks. initial tested materials measured with microhardness tester 1...
For stem cell differentiation, the microenvironment can play an important role, and hydrogels provide a three-dimensional to allow native growth in vitro. A challenge is that cell's differentiation be influenced by matrix stiffness. We demonstrate low-toxicity method create different stiffness matrices, using photopolymerizable gelatin methacrylate (GelMA) hydrogel cross-linked blue light (440 nm). The porosity of GelMA easily modified altering its concentration. used human bone marrow...
Penetrating neck trauma has traditionally been evaluated by surgical exploration and/or invasive diagnostic studies. We hypothesized that computed tomography (CT), used as an early tool to accurately determine trajectory, would direct or eliminate further studies procedures in stable patients with penetrating trauma.Retrospective case series.Academic, urban, level I center.Hemodynamically without hard signs of vascular injury aerodigestive violation who had sustained the neck.Patients...
Hinokitiol displays potent antimicrobial activity. It has been used in toothpaste and oral-care gel to improve the oral lichen planus reduce halitosis. The aim of this study was evaluate activity 3 different dental root canal sealers with hinokitiol (sealers+H) their physical biological effects. AH Plus (epoxy amine resin-based, AH), Apexit (calcium-hydroxide-based, AP), Canals (zinc-oxide-eugenol-based, CA), were study. original CA exhibited strong anti-methicillin-resistant Staphylococcus...
In this study, three PCL-based polyurethane acrylates were synthesized and further formulated into twelve resins for digital light processing (DLP) 3D printing. Three PCL diols with different molecular weights via ring-opening reaction of ε-caprolactone on diethylene glycol, the catalyst stannous octoate. Isophorone diisocyanate (IPDI) was reacted 2-hydroxyethyl acrylate (2-HEA) form acrylates. Twelve composed percentages acrylates, poly (ethylene glycol) diacrylate (PEGDA), propylene glycol...
Objective: To evaluate the clinical efficiency and patient acceptance during cavity preparation in children, a direct comparison was made between Er:YAG laser conventional mechanical of caries using split-mouth design. Background Data: The system developed for cutting dental hard tissue has been approved as useful alternative method preparation. Methods: Children with previously unrestored matched carious cavities non-pulpally involved anterior teeth were selected, sequential order treatment...
The aim of this research is to synthesize polycaprolactone-based polyurethanes (PCL-based PUs) that can be further used for the fabrication guided bone regeneration (GBR) membranes with higher tensile strength and elongation at break than collagen PTFE membranes. PCL-based PUs were prepared by polymerization polycaprolactone (PCL) diol 1,6-hexamethylene diisocyanate (HDI) different ratios using either polyethylene glycol (PEG) or ethylenediamine (EDA) as chain extenders. chemical,...
The aims of this study were to examine the effect implant neck design and cortical bone thickness using 3D finite element analysis analyse stability clinical evidence based on micromotion principal stress. Four commercial dental implants for a type IV maxillary segments created. Various parameters considered, including osseointegration condition, loading direction thickness. Micromotion stresses used evaluate failure overloading, respectively. It was found that maximum stress peri-implant...
We characterized and imaged dental calculus using swept-source optical coherence tomography (SS-OCT). The refractive indices of enamel, dentin, cementum, were measured as 1.625 ± 0.024, 1.534 0.029, 1.570 0.021, 2.097 0.094, respectively. Dental leads strong scattering properties, thus, the region can be identified from enamel with SS-OCT imaging. An extracted human tooth is covered gingiva tissue an in vitro sample for tomographic
Cytotoxic effects of resin liquids three in situ relining dental polymers, Alike, Kooliner, and Tokuso Rebase, their major components, methyl methacrylate (MMA), isobutyl (IBMA), 1,6-hexanediol dimethacrylate (1,6-HDMA) were investigated. The concentrations monomers these determined by high-performance liquid chromatography. Cellular viability human gingival fibroblasts (GF) periodontal ligament (PDL) cells evaluated the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide assay....
Abstract Collagen sponges are widely used scaffolds in bone engineering. To form bone, the osteoblastic cells undergo proliferation, differentiation, and mineralization stages scaffold. Crosslinking freezing temperature two important variables fabricating collagen sponges. The purpose of this study was to examine responses prepared with or without glutaraldehyde crosslinking at different temperatures (−20°C −80°C). MC3T3‐E1 were cultured differently Osteoblastic examined included cell...
