The purpose was to evaluate the effect of a hydrophilic amide monomer on μTBS one-step adhesive dentin at different application times. Clearfil Universal Bond Quick (UBQ), experimental (UBQexp; same compositions as UBQ but replaced with 2-hydroxyethyl methacrylate), SE ONE and were applied midcoronal prepared 600-grit SiC time (0, 10, 20 40 s). Water sorption (Wsp) ultimate tensile strength (UTS) polymerized adhesives also measured. showed significantly lower Wsp higher UTS than UBQexp. At...

By introducing an invariant of loops on a compact oriented surface with one boundary component, we give explicit formula for the action Dehn twists completed group ring fundamental surface. is can be considered as “the logarithms” twists. e generalizes classical describing rst homology surface, and Morita’s computations extended second Johnson homomorphisms. For proof use homological interpretation Goldman Lie algebra in framework Kontsevich’s formal symplectic geometry. As application,...

We provide some language for algebraic study of the mapping class groups surfaces with non-connected boundary. As applications, we generalize our previous results on Dehn twists to any compact connected oriented non-empty Moreover embed `smallest' Torelli group in sense Putman into a pro-nilpotent coming from Goldman Lie algebra. The graded quotients embedding equal Johnson homomorphisms all degrees if boundary is connected.

The influence of sulfinate agents applied as a dentin pretreatment or mixture with multi-mode one-step self-etch adhesives (1-SEAs) on the degree conversion (DC) and micro-tensile bond strength (μTBS) light-cured 1-SEAs was investigated. Clearfil Universal Bond Quick (UBQ) Scotchbond Adhesive (SBU) were to in etch&rinse mode using various application strategies: 1) no pretreatment, 2) 90 wt% ethanol, 3) agent DC Activator (UDC) DCA (SDC), 4) UBQ+UDC SBU+SDC. μTBS measured after 24 h....

Abstract The solubility of tri-n-butylphosphate (TBP) in aqueous solutions plutonium nitrate (PuN) and highly radioactive liquid waste (HRLW) PUREX nuclear fuel reprocessing was investigated. By an empirical formula the TBP PuN described range 0–0. 1 M Pu 1–8M HNO3 concentrations. following items were elucidated: (1) logarithm (S) solution interest varies inversely proportion to concentration Pu(IV) 0–0.1M PU(IV) at a constant HNO3, indicating that simply behaves as electrolyte for...

For any unoriented loop on a compact connected oriented surface with one boundary component, the generalized Dehn twist along is defined as an automorphism of completed group ring fundamental surface. If simple, this usual right handed twist, in particular realized mapping class We investigate case when has single transverse double point, and show that not class.

Multilateral Nuclear Approaches (MNAs) is a concept of international and/or multilateral control nuclear material fuel cycle facilities. It strategy for contributing to and promoting the sustainability energy while enhancing nonproliferation, by ensuring supplies services, risk reducing regarding safety. In order establish such MNA, authors draw out 12 features MNA analyzing various past current proposals, together with environment surrounding use. Those proposals are: (A) (B) assurance...

Let $\Sigma$ be a compact oriented surface. The Dehn twist along every simple closed curve $\gamma \subset \Sigma$ induces an automorphism of the fundamental group $\pi$ $\Sigma$. There are two possible ways to generalize such automorphisms if $\gamma$ is allowed have self-intersections. One way consider `generalized twist' $\gamma$: Malcev completion whose definition involves intersection operations and only depends on homotopy class $[\gamma]\in \pi$ $\gamma$. Another choose in usual...

Abstract We present a formula expressing Earle's twisted 1-cocycle on the mapping class group of closed oriented surface genus ≥ 2 relative to fixed base point, with coefficients in first homology surface. For this purpose we compare it Morita's which is combinatorial. The key computation these cocycles particular element group, topologically hyperelliptic involution.
