I n situ nitrogen-ion implantation of polycrystalline niobium and tantalum was performed and the surface was characterized by x-ray photoelectron spectroscopy (XPS). The XPS chemical shifts indicated the formation of metal nitride. The chemical shift values are calculated theoretically and compared with the experiment…

The optical transfer matrix technique for the analysis of optical harmonic generation and mixing in laminar structures is extended to include the case of anisotropic media. This approach is applicable in the limit of low conversion efficiencies, where attenuation and phase shifts of the pump beams due to nonlinear int…

The influence of oxygen vacancies on the electronic structure of yttrium oxide was investigated both experimentally and theoretically. By means of X‐ray absorption spectroscopy, at the yttrium K and L 11 edges and at the oxygen K edge, information on the local densities of states of various orbital symmetries, around…

The ordinary control method, pulse width modulation (PWM) control method, for the shape memory alloy (SMA) actuator has a basic defect: the response of an SMA actuator controlled by this method is very slow, because the maxi mum voltage supplied to the SMA must be kept low in order to prevent the SMA from burning beca…

Corrosion inhibition of steel (ASTM A619) by two marine isolates, Pseudomonas sp.S9 and Serratia marces‐cens EF190, was investigated by weight loss measurements of metal coupons placed in static batch cultures. Artificial seawater with (VNSS) and without (NSS) nutrients was used. The effects of bulk‐ and surface local…

Summary This paper presents a model for predicting the scaling tendencies of barium, strontium, and calcium sulfates resulting from the mixing of injected and formation waters and from temperature and pressure effects. The model also predicts competitive simultaneous coprecipitation of BaSO4, CaSO4, and SrSO4, where s…

Transcription of the fibroin gene can be reconstituted with partially purified components from HeLa cells. Transcription factors IIB, IID, and IIE and RNA polymerase II are required for accurate initiation of transcription. Linear and relaxed closed circular DNA show a similar level of template activity. However, tran…

Abstract We consider large eigenvalue problems for skeletal structures with symmetry. We present an algorithm, based upon a novel combination of group‐theoretic ideas and substructuring techniques, that block‐diagonalizes such systems exactly and efficiently. The procedure requires only the structural matrices of a re…

It is shown that quantitative X-ray powder diffraction analyses using full profile multiphase refinement should include corrections for the Brindley particle absorption contrast effect. This is demonstrated with synthetic mixtures of the highly contrasting phases LiF and Pb(NO3)2 (μ/ρ = 20 and 231 cm−1 for Co Kα). Wit…
