Mixture of the trimethylchlorosilane, magnesium and hexamethylphosphorictriamid, HMPT, react with epoxyketones to produce tetrasiliciated compounds, which are the results of the addition of two trimethylsilyl (TMS) groups to the carbonyl function and two TMS groups to the expoxide cycle. After elimination of (Me Si) O siliciated enoxysilanes are obtained which under acidic conditions gives ...

The membrane potentials for asymmetric membranes where fixed charges varied linearly with position were evaluated from the numerical solutions of Nernst-Planck flux and Donnan potential equations. The evaluated membrane potentials were compared with the results obtained from the conventional TMS theory where the fixed charge concentration in the membrane was assumed to be uniform. In the compar...

With the rapid growth of globalization, distributed teams have become increasingly common in organizations. This research investigates the impact of inter-subgroup dynamics on knowledge coordination in distributed teams. To address this research question, we extend and apply theory from two primary sources – Transactive Memory Systems (TMS) theory and the faultline model. The paper uses data co...

The Bolivian inflation process is analyzed utilizing a time-varying univariate and multivariate Markov-switching model (TMS). With monthly data and, beginning in the late 1930s, accurately described by TMS. intercept for high-inflation regime significantly higher than low-inflation actual rate mirrors smoothing probabilities of Markov process. Additionally, predicted duration each closely fits ...

This study examines the effects of TMS of the right PPC on the latency of saccades and vergence alone or combined and the role of experimental design. Two designs were used: pure blocks with exclusively no-TMS or TMS trials; mixed blocks in which no-TMS and TMS trials were interleaved; a control study with TMS of the primary motor cortex (pure blocks) was also conducted and showed no effects on...

OBJECTIVE To further evaluate the potential of slew-rate limiting amplifiers to record electrophysiological signals in spite of concurrent transcranial magnetic stimulation (TMS), and to explore the effects of single-pulse TMS on electroencephalographic (EEG) correlates of functional brain activity. METHODS Visual-evoked potentials (VEPs) to checkerboards were recorded in 7 right-handed subje...

The acquisition problem in wavelet-based modulation is very important. We discuss the problem of the MLbased method proposed in [1] for timing acquisition and then we develop a novel acquisition algorithm. Our method uses the properties of the scaling function in the derivation of the acquisition function. We also show that the S-curve of our acquisition algorithm is smooth and has a unique zer...

Tetranitromethane (T.N.M.) occurs in the production of T.N.T. as a byproduct of toluene nitration. It is a highly toxic substance, and its toxic properties have been recently investigated by Sievers, Rushing, Gay, and Monaco (1947). According to them, the maximum allowable concentration of T.N.M. is less than 5 p.p.m. Elkins (1950) recommends 0-5 p.p.m. or 4 mg./m.3 of air as the safe maximum a...
