The spectrum of 249Bk, excited in an electrodeless lamp, has been recorded between 3700 and 12,000 cm?1 on a Fourier-transform spectrometer. The strongest 90 lines are listed along with the classification for 77 of them. The lowest levels of the 5f96d7s, 5f97s7p, 5f97s8s, 5f86d7s2 , 5f87s27p and 5f86d7s7p configurations of Bk I and of the 5f96d and 5f97p configurations of Bk II have been identified. Lists of the energies and hfs data of the Bk I levels involved in the i.r. transitions are also included. 相似文献

A theoretical analysis is made of the stresses induced in thin elastic strips which are bent (by uniform bending moments) into arcs with substantially constant radii of curvatures. Stresses determined experimentally on aluminum and steel strips agree very well with the theory. 相似文献

The new synergic base [PMDETA.K(TMP)(Et)Zn(Et)] selectively zincates 4-(dimethylamino)pyridine at the 2-position and 4-methoxypyridine at the 3-position, to afford bimetallic potassium pyridylzinc complexes each displaying a novel, but remarkably different, structure. 相似文献

A substantial number of new indefinite integrals involving the incomplete elliptic integral of the third kind are presented, together with a few integrals for the other two kinds of incomplete elliptic integral. These have been derived using a Lagrangian method which is based on the differential equations which these functions satisfy. Techniques for obtaining new integrals are discussed, together with transformations of the governing differential equations. Integrals involving products combining elliptic integrals of different kinds are also presented. 相似文献

Isoxazole‐Derived Amino Acids are Bromodomain‐Binding Acetyl‐Lysine Mimics: Incorporation into Histone H4 Peptides and Histone H3 下载免费PDF全文
Angelina R. Sekirnik David S. Hewings Natalie H. Theodoulou Lukass Jursins Katie R. Lewendon Laura E. Jennings Timothy P. C. Rooney Tom D. Heightman Stuart J. Conway 《Angewandte Chemie (International ed. in English)》2016,55(29):8353-8357
A range of isoxazole‐containing amino acids was synthesized that displaced acetyl‐lysine‐containing peptides from the BAZ2A, BRD4(1), and BRD9 bromodomains. Three of these amino acids were incorporated into a histone H4‐mimicking peptide and their affinity for BRD4(1) was assessed. Affinities of the isoxazole‐containing peptides are comparable to those of a hyperacetylated histone H4‐mimicking cognate peptide, and demonstrated a dependence on the position at which the unnatural residue was incorporated. An isoxazole‐based alkylating agent was developed to selectively alkylate cysteine residues in situ. Selective monoalkylation of a histone H4‐mimicking peptide, containing a lysine to cysteine residue substitution (K12C), resulted in acetyl‐lysine mimic incorporation, with high affinity for the BRD4 bromodomain. The same technology was used to alkylate a K18C mutant of histone H3. 相似文献

The temperature and pH effects on the equilibrium of a blood plasma model have been studied on the basis of artificial neural
networks. The proposed blood plasma was modeled considering two important metals, calcium and magnesium, and six ligands,
namely, alanate, carbonate, citrate, glycinate, histidinate and succinate. A large data set has been used to simulate different
concentrations of magnesium and calcium as a function of temperature and pH and these data were used for training the neural
network. The proposed model allowed different types of analyses, such as the effects of pH on calcium and magnesium concentrations,
the competition between calcium and magnesium for ligands and the effects of temperature on calcium and magnesium concentrations.
The model developed was also used to predict how the variation of calcium concentration can affect magnesium concentrations.
A comparison of neural network predictions against experimental data produced errors of about 3%. Moreover, in agreement with
experimental measurements (Wang et al. in Arch. Pathol. 126:947–950, 2002; Heining et al. in Scand. J. Clin. Lab. Invest. 43:709–714, 1983), the artificial neural network predicted that calcium and magnesium concentrations decrease when pH increases.
Similarly, the magnesium concentrations are less sensitive than calcium concentrations to pH changes. It is also found that
both calcium and magnesium concentrations decrease when the temperature increases. Finally, the theoretical model also predicted
that an increase of calcium concentrations will lead to an increase of magnesium concentration almost at the same rate. These
results suggest that artificial neural networks can be efficiently applied as a complementary tool for studying metal ion
complexation, with especial attention to the blood plasma analysis.

A resin‐bound dinuclear zinc(II) complex for the selective capture of pyrophosphopeptides is reported. The metal complex binds diphosphate esters over other anionic groups, such as monophosphate esters, sulfate esters, and carboxylic acids, with high specificity. Immobilization of the compound provided a reagent capable of binding and retaining nanomolar quantities of pyrophosphopeptide in the presence of cell lysate. The high affinity and specificity of the reagent makes it an attractive tool for the study of in vivo pyrophosphorylation. 相似文献
