A series of rare-earth-metal-hydrocarbyl complexes bearing N-type functionalized cyclopentadienyl (Cp) and fluorenyl (Flu) ligands were facilely synthesized. Treatment of [Y(CH(2)SiMe(3))(3)(thf)(2)] with equimolar amount of the electron-donating aminophenyl-Cp ligand C(5)Me(4)H-C(6)H(4)-o-NMe(2) afforded the corresponding binuclear monoalkyl complex [({C(5)Me(4)-C(6)H(4)-o-NMe(μ-CH(2))}Y{CH(2)...

General experimental procedures. All manipulations were performed under a dry and oxygen-free argon atmosphere using standard high-vacuum Schlenk techniques or in a glovebox. All solvents were purified via a SPS system. 1 H and 13 C NMR spectra were recorded on a Bruker AV400 (FT, 400 MHz for 1 H; 100 MHz for 13 C) spectrometer. The molecular weight (M n) was measured by TOSOH HLC-8220 GPC at 4...

This investigation concerns with the mechanical efficiency of Cardan joints. The model includes also the effects due to manufacturing and mounting errors and the influence of rotation speed on the efficiency. The joint has been modeled as an RCCC spatial linkage and the full dynamic analysis performed by means of dual vectors algebra. NOMENCLATURE [ Â ]i+1 i Dual transform matrix. ai Minimum di...

Responses of single cells in the macaque lateral geniculate nucleus were recordedthrough extracelltiar micropipettes. Spectral sensitivity of each cell was determined byrecording its responses to 6 diffuse monochromatic photic stimuli. Activity in a pre-determined limited area of striate cortex was then temporarily removed by cooling andresponses to the same photic stimuli were ...

The R gene in maize, conditioning anthrocyanin formation in seed and plant, invariably is changed from a darkly pigmenting to a weakly pigmenting (repressed) form in the progeny of heterozygotes carrying the stippled (Rst) allele. The repressed forms of R are gametically transmitted, and are referred to as paramutant (R') alleles.' 3 The evidence presented in this report shows that R' alleles a...

P folding has been a long-lived problem in biophysics. Much important progress has been made in the 90s by focusing on small single-domain proteins (1). In particular, (i) site-resolved measurement of the folding transition state ensemble, quantified as f-values (2), made it possible to understand folding mechanisms relatively unambiguously, stimulating interaction between experimentalists and ...

This paper aims to develop a writing robot by recognizing the speech signal from the user. The robot arm constructed mainly for the disabled people who can’t perform writing on their own. Here, dynamic time warping (DTW) algorithm is used to recognize the speech signal from the user. The action performed by the robot arm in the environment is done by reducing the redundancy which frequently fac...

A historical survey and critical evaluation concerning discipleship in the Fourth Gospel The historical survey about discipleship in the Fourth Gospel indicates that the literature of the second half of this century was sketchy about this theme. Up till 1972 a thematic-theological approach highlighted some characteristics of discipleship as they appeared in all four gospels. The study of Jimene...
