N4-Ethyl-L-[u-14C]asparagine and L-[U-14C]aspartate give identical metabolites, mainly intermediates of the tricarboxylic acid cycle and related amino acids, in whole cells of Pseudomonas stutzeri. The labelled asparagine derivative is converted into [14C]-aspartate by cell-free extracts, and this reaction, which has an optimum pH of 8.8 +/- 0.2, is neither inhibited by unlabelled asparagine no...

(1)H and (13)C NMR spectra of allyl isothiocyanate (AITC) were measured, and the exchange dynamics were studied to explain the near-silence of the ITC carbon in (13)C NMR spectra. The dihedral angles α = ∠(C1-C2-C3-N4) and β = ∠(C2-C3-N4-C5) describe the conformational dynamics (conformation change), and the bond angles γ = ∠(C3-N4-C5) and ε = ∠(N4-C5-S6) dominate the molecular dynamics (confor...

Event-related brain potentials (ERPs) are altered in patients with a variety of psychiatric disorders and may represent quantitative correlates of disease liability that are more amenable to genetic analysis than disease status itself. Results of a genomewide linkage screen are presented for amplitude of the N4 and P3 components of the ERP, measured at 19 scalp locations in response to a semant...

Two bacteriophages, RPP1 and RLP1, infecting members of the marine Roseobacter clade were isolated from seawater. Their linear genomes are 74.7 and 74.6 kb and encode 91 and 92 coding DNA sequences, respectively. Around 30% of these are homologous to genes found in Enterobacter phage N4. Comparative genomics of these two new Roseobacter phages and 23 other sequenced N4-like phages (three infect...

The following metabolites of sulfadiazine (S) were isolated from monkey urine by preparative HPLC: 5-hydroxysulfadiazine (5OH), 4-hydroxysulfadiazine (4OH) and the glucuronide (5OHgluc) and sulfate conjugate of 5OH (5OHsulf). The compounds were identified by NMR, mass and infrared spectrometry and hydrolysis by beta-glucuronidase. The analysis of S, the hydroxymetabolites (4OH, 5OH) and conjuga...

We report the redshift measurement for the submillimeter selected galaxy SMMJ04431+0210 (N4) using the Near Infrared Spectrograph on the Keck II telescope. The data show Hα, [NII] 6583,6548, and [OIII] 5007 lines at a redshift of z = 2.51. The high nuclear [NII]/Hα line ratio is consistent with a LINER or Type-II AGN. The Hα emission is spatially resolved, suggesting the presence of significant...

We show, with an elementary proof, that the number of halving simplices in a set of n points in R4 in general position is O(n4−2/45). This improves the previous bound of O(n4−1/13 4 ). Our main new ingredient is a bound on the maximum number of halving simplices intersecting a fixed 2-plane.

H and C NMR spectra of allyl isothiocyanate (AITC) were measured, and the exchange dynamics were studied to explain the near-silence of the ITC carbon in C NMR spectra. The dihedral angles α = ∠(C1−C2−C3−N4) and β = ∠(C2−C3−N4−C5) describe the conformational dynamics (conformation change), and the bond angles γ = ∠(C3−N4−C5) and ε = ∠(N4−C5−S6) dominate the molecular dynamics (conformer flexibi...

In this paper, the equation of motion of an elastic 2 DoF wing model has been derived using Lagranges method. The aerodynamic loads on the wing were calculated via the Strip-Theory and the effect of compressibility was included. Wing deflections due to bending and twist motions were determined using the Assume-Mode method. The aeroelastic equations were solved numerically using the V-g method. ...
