We update our Standard Model predictions for g-2 of the muon and for the hadronic contributions to the running of the QED coupling,αh(5a)d(MZ2).Particular emphasis is put on recent changes in the hadronic contributions from new data in the 2π channel and from the energy region just below 2 GeV. 相似文献

The on-demand release of antibacterial components due to pH variations caused by acidogenic/cariogenic bacteria is a possible design for smart antibacterial restorative materials. This study aimed to fabricate pH-responsive Zn2+-releasing glass particles and evaluate their solubilities, ion-releasing characteristics, and antibacterial properties in vitro. Three kinds of silicate-based glass particles containing different molar ratios of Zn (PG-1: 25.3; PG-2: 34.6; PG-3: 42.7 mol%) were fabricated. Each particle was immersed in a pH-adjusted medium, and the solubility and concentration of the released ions were determined. To evaluate the antibacterial effect, Streptococcus mutans was cultured in the pH-adjusted medium in the presence of each particle, and the bacterial number was counted. The solubility and concentration of Zn2+ released in the medium increased with a decrease in medium pH. PG-3 with a greater content of Zn demonstrated higher concentrations of released Zn2+ compared with PG-1 and PG-2. PG-2 exhibited bactericidal effects at pH 5.1, whereas PG-3 demonstrated bactericidal effects at pH values of 5.1 and 6.1, indicating that PG-3 was effective at inhibiting S. mutans even under slightly acidic conditions. The glass particle with 42.7 mol% Zn may be useful for developing smart antibacterial restoratives that contribute to the prevention of diseases such as caries on root surfaces with lower acid resistance. 相似文献

During our investigation concerned with the free-radical crosslinking copolymerization of benzyl methacrylate with neopentyl glycol dimethacrylate in the presence of lauryl mercaptan as a chain transfer agent with the intention to remove the obstacles between allyl and vinyl polymerizations, we observed, by chance, popcorn formation in spite of the presence of a large amount of chain transfer agent. 相似文献

A main goal for manufacturing systems is to shorten lead‐time for the development of new products. An important challenge is to make sound decisions at early stages of product development where committed costs are low which leads us to obtain a lower total cost. This could mean that incurred costs are higher in the beginning where more work has to be done in terms of learning the market, developing the product and the production system. An important feature is to avoid changes at later stages where the incurred costs are high. The stereolithography using photo curable liquid resin is important for the manufacturing. The technology based on the stereolithography has been widely accepted due to the phenomena of spreading “Information Technology (IT)” and three‐dimensional computer aided design (3D CAD) system. The stereolithography technique has become very popular in the field of automotive, home‐electronics industries. In this paper the photo curable liquid resins for the stereolithography system are reviewed. 相似文献
