Summary The bending of a finite-length beam that lies on a rigid, rough, flat foundation and interacts with it in accordance to the
dry friction law is considered. Loading by bending moments applied at the ends of the beam is studied in detail. The problem
is found to be a self-similar one. For small moments, the central part of the beam remains undeflected, and the problem reduces
to the solution of an infinite system of algebraic equations. Large moments deflect the entire length of the beam, and the
problem partly loses its self-similarity. In this case, the problem reduces to the solution of a successively decreasing number
of ordinary differential equations along with some algebraical equations. The solution for the latter case provides initial
conditions for the former one. This permits to obtain a solution for any value of the moment.

A reversed-phase high-performance liquid chromatographic (HPLC) analysis of bile pigments is described that provides baseline separation of the major bilirubin conjugates found in bile. The advantage of the technique is that the bile pigments can be analyzed directly as their native tetrapyrroles without prior solvent extractions or derivatization. The use of ammonium acetate in place of sodium salts permits preparative isolation and lyophilization of the pigments for mass spectroscopy. The derivatization of the pigments as their dipyrrolic azosulfanilates with subsequent HPLC analysis demonstrates baseline separation of the endo- and exovinyl azodipyrroles and allows identification of that half of the tetrapyrrole which contains the conjugate in the instances of monoglycosides. 相似文献

The radiation pattern has been determined on the basis of the comparative analysis of auroral kilometric radiation (AKR) received
in the space-diversity mode by two satellites, Interball-2 and Polar. The radiation propagates in a cone with an opening angle
∼±25° and the axis aligned with the local magnetic field. The results con-firm the theoretical estimates that the source boundaries
play a significant role in the generation of the auroral kilometric radiation and in the formation of the radiation pattern.

A novel technique for determining the relative accessibility and reactivity of basic surface hydroxyl sites by reacting various zirconium(IV) hydroxide materials with 2,2,2-trifluoroethanol (TFE) and characterizing the resulting material using (19)F magic angle spinning (MAS) nuclear magnetic resonance (NMR) is presented here. Studied here are three zirconium hydroxide samples, two unperturbed commercial materials, and one commercial material that is crushed by a pellet press. Factors, such as the ratio of bridging/terminal hydroxyls, surface area, and pore size distribution, are examined and found to affect the ability of the zirconium(IV) hydroxide to react with TFE. X-ray diffraction, nitrogen isotherms, and (1)H MAS NMR were used to characterize the unperturbed materials, while thermogravitric analysis with gas chromatography and mass spectrometry along with the (19)F MAS NMR were used to characterize the materials that were reacted with TFE. Zirconium hydroxide materials with a high surface area and a low bridging/terminal hydroxyl ratio were found to react TFE in the greatest amounts. 相似文献

The non-perturbative effects for the Quark-Gluon Plasma (QGP) equation of state (EoS) are considered. The modifications of the bag model EoS are constructed to satisfy the main qualitative features observed for the QGP EoS in the lattice QCD calculations. A quantitative comparison with the lattice results is done for the SU(3) gluon plasma and for the QGP with dynamical quarks. Our analysis advocates a negative value of the bag constant B. 相似文献
