Coprimely packed rings
(1988)An ideal I of a commutative ring R with identity is said to be coprimely packed by prime ideals of R if whenever I is coprime to each element of a family of prime ideals of R, I is not contained in the union of prime ideals ... 
Oxidation of alcohol monolayers by chromic acid
(1988)Reactions in monolayer assemblies provide the opportunity to examine the reactivity of molecules constrained to the plane. This environment can produce novel effects; e.g., we recently reported that the cyclization of the ... 
Spectral response of nonlinear magnetic conductors
(1988)A general procedure for predicting the amplitudes of the magnetic induction components, resulting from multisinusoidal excitation of a nonlinear magnetic conductor, is presented. The magnetisation curve of the magnetic ... 
Preparation effects on the spectroscopic properties of V2O5GeO2 glass
(Kluwer Academic PublishersPlenum Publishers, 1988)The spectroscopic studies of V2O5GeO2 (45:55) glasses fused and equilibrated at various temperatures (T?{symbol}) in air were measured. Their spectroscopic properties are shown to be sensitive to microstructure. This ... 
A note on the nonlinear distortion performance of the MachZehnder electrooptic modulator
(Kluwer Academic PublishersPlenum Publishers, 1988)A generalised large voltage analysis is presented for the MachZehnder modulator and closedform expressions are derived for the output harmonics and intermodulation products. Results obtained previously, for small voltages, ... 
Harmonic and intermodulation distortion in condenser microphones
(1988)A simple formula is presented for the inputoutput characteristic of the condenser microphone. Also, a closedform expression is derived for the output voltage of a condenser microphone excited by a multitone acoustic input ... 
Optimum design of nonlinear space trusses
(1988)The structural optimization algorithms developed in recent years mainly consider the elastic behaviour of structures. The reserve of resisting loads in nonlinear regions is totally ignored. The optimum design algorithm ... 
Methods with O(H4) and O(H6) PhaseLags for Periodic Initial Value Problems
(1988)Two families of computational methods are discussed for the solution of second order periodic initial value problems. The first is a family with O(H4) phaselag, the periodicity equation coinciding with the periodicity ... 
A note on the harmonic distortion in acbias recording
(1988)A new analytical expression for approximating the error function erf (x) is presented. Using this expression, analytical closedform expressions are obtained for the overall record and playback nonlinear distortion resulting ... 
The electronic and optical properties of germanium tellurite glasses containing various transition metal oxides
(1988)Various transition metal oxides, such as TiO2, V2O5, NiO, CuO, and ZnO are added to germanium?tellurite glass and measurements are reported of the electrical conductivity, density, optical absorption, infra?red absorption ... 
An anomalous conduction phenomenon in the ZN: Xfecro4Ni, system
(1988)D.c. conductivity measurements carried out on ZnFeCrO4have revealed a new conduction phenomenon. It was found that for temperatures above 360 K conduction is similar to that of semiconductors, obeying the relationship ... 
Threecolours photoelectric observations of W UMAsystem BB Pegasi
(Kluwer Academic Publishers, 1988)The paper gives UBV photoelectric light curves of the eclipsing binary BB Peg obtained in one of the nights in August 1982 and four nights of November 1984. A comparison has been made with previous light curves of this ... 
Preliminary studies on some coliphages from Kuwait.
(1988)Seasonal data for raw sewage indicated a higher concentration of bacteriophages in the warmer months compared with the cooler months. Regardless of the amount of phages in the raw sewage and the time of year the efficiency ... 
Contribution to the study of solar radiation in Abu Dhabi
(1988)Measurements of global solar radiation for 10 yr in Abu Dhabi are used to examine the suitability of a method of prediction of global solar radiation. It shows a good degree of accuracy. A correlation between the clearness ...
