Sm systems

The Cp2VCl2/R3SiCl/Zn catalytic system can be used for the reductive coupling of the imines 29 (Scheme 18) [55]. These components of the ternary catalyst are essential and, interestingly, meso-diastereoselectivity is observed in contrast to the coupling with cat. Cp2TiCl2/Sm system. The selectivity de-... [Pg.75]

The results obtained for the monomer, the dimer and the CP-corrected system of the He2 dimer are given in Table I. Under heading Dimer , e.g., the contributions of the given functions from the atomic basis set of (any of) the He-atoms are tabulated, as they participate in the occupied SMO of the dimer (SM-) system. The contributions for the CP-system is tabulated in a simitar way. [Pg.235]

These contributions are not existing for the He atom, but as to the values for the SM and CP systems, they are systematically different (the contributions from the CP system are larger than those fi om the SM system). A quite different conclusion holds for the ghost contributions these values, calculated in the dimer system are much higher (for some functions with one or two magnitudes ) than in the CP system. This is contrary to common belief the lower total energy of a CP... [Pg.235]

One of the most significant events in explosives history has been the development of the IRECO Chemicals Site-Mixed-Slurry (SMS) system, commonly referred to as the pump truck system, which is today the safest blasting system known. Nonexplosive raw materials are carried by the pump truck from the storage area to the borehole site where they then become an explosive capable... [Pg.398]

The first SMS system was established for the Kaiser Steel iron ore operation at Eagle Mountain, California. The first SMS system outside North America was established in early 1965 at Phalaborwa, Sorth Africa, for the Palabora Mining Company. Shortly thereafter the SMS system was established in rapid succession for mining operations throughout the world... [Pg.398]

Eu—Sm system. — Lowering of the melting point of samarium from 1072° to 1052° C has been observed [248] by adding 0.2% of Eu.However, the a transition temperature of samarium remained unchanged. [Pg.115]

A monoamide complex was obtained with [OCtBu(2-CH2-NC5H3-6-Me)2] as a co-ligand (Fig. 19) [127]. The overall structure features are very similar to the aforementioned homoleptic Sm-system except that a monodentate alkoxide ligand has been replaced by a N(SiMe3)2 group. The amide group makes the complex soluble in aliphatic hydrocarbons. [Pg.179]

Some of the earliest studies of organolanthanide chemistry described reactions of the elemental metals with alkyl and aryl iodide reagents (RI) (67). Analysis of the soluble products obtained for Ln = Eu, Yb, Sm indicated a formula of primarily RLnl although it was acknowledged that this could represent a number of different species in equilibrium. The amount of contamination of the divalent product with trivalent species was observed to follow the order of stability of the divalent states the Eu system was the cleanest, while the Sm system had only 50% of the metal in the divalent state. These species reacted like Grignard reagents. The... [Pg.153]

We use a simple picture in which the molecular species S is a two-state system, where the oxidized state ) has one electron more than the reduced state b. The corresponding energies are a and /, and their difference is denoted Eab = Ea—Ey. For the metal electrode we use a free electron model, so that a state of the metal is specified by a set of occupation numbers m = (/ i, m, . ..) ofthe single electron levels. For the single electron level j of energy Ej, mj = 1 with probability f Ej) and mj = 0 with probability 1 —/ Ej), where/( ) is given by (17.4). A basis of states forthe overall SM system is written s, m) = Iv) m) where s = a,b and m) is an antisymmetrized product of single electron metal states. [Pg.611]

The notion of sines plus noise modeling was posed and implemented by Xavier Serra and Julius Smith in the Spectral Modeling Synthesis (SMS) system. They called the sinusoidal components the deterministic component of the signal, and the leftover noise part the residual or stochastic component. Figure 6.12 shows the decomposition of a sung ahh sound into deterministic (harmonic sinusoidal) and stochastic (noise residue) components. [Pg.69]

Density. This property was found to be useful for a first selection of the polysulfide crystals. In each of the Nd, Pr and Sm systems 20-30 crystals selected randomly showed identical density, giving a good proof of phase uniformity of all these crystals. For the Dy crystals there was considerable scatter in density values, and only a histogram based on 100 measurements with well-defined maxinoa allowed the polysulfides with different density and hence with different compositions to be observed. At least two polysulfide phases were identified according to this histogram. The scatter still persists between the... [Pg.586]

EM pumps of both primary units trip with the flow coastdown facilitated by the synchronous motor (SM) system then the fuel and coolant temperatures rise because of the coolant flow decrease. However, the reactor power is decreased via the negative feedbacks resulting from Doppler, fuel expansion, and steel and coolant reactivity coefficients. After the flow coastdown by the SM systems, the primary coolant circulates within the reactor vessel, driven by natural convection, with a flow rate of approximately 20% of the nominal. Then, the inherently decreased power and the convection flow rate are balanced to a steady state. [Pg.411]

After the reactor shutdown, primary pumps trip with the flow coastdown facilitated by the SM system then natural circulation begins within the reactor vessel. Coolant temperature in the hot plenum (upper core region) decreases because of the shutdown. Only the RVACS with reduced draft removes decay heat by air convection. Temperatures in the primary boundary... [Pg.413]

In the case of the composite sample containing 40% of liquid crystal, the contact angle of the PVAB/Sm systems has values in the moderate wettability domain (65°). This value is close to that of the natural cornea (Duran-Sampedro et al. 2013), suggesting potential biomedical applications as contact lenses or other ocular devices, such as an artificial iris (Hsu et al. 2011 Lapointe et al. 2010). [Pg.134]

Table 2 lists the state energies and symmetries for the R2CUO4 system (R = Nd, Pr, Sm) system. The best set of CEF parameters derived from these data is listed in table 3. [Pg.503]

I was evaluating a transport company s SMS and found it was great on paper. But when we interviewed employees, we found that nobody followed it, not even the CEO. Remember write down in the SMS System Safety Program Plan only what you really do. [Pg.101]
