In this article we introduce the difference sequence space m(M, Δ, φ) using the Orlicz function. We study its different properties like solidity, completeness etc. Also we obtain some inclusion
relations involving the space m(M, Δ, φ).

The rate of energy loss of the impinging ion as it passes through succeeding layers of the target material gives information regarding the nature of the material and helps to calculate the range of the ions in a thick target in which the ions are stopped. In the present work, the range of 118 MeV 28Si was measured in different types of polycarbonates, viz. Makrofol-N, Makrofol-G and Makrofol-KG, using the nuclear track technique. Polyallyldiglycol carbonate (PADC) was used as the backing detector. The experimental values of range and energy-loss rate are compared with the theoretical values obtained from different computer codes, viz. BENTON, HUBERT, RANGE, TRIM’98 and SRIM’03. 相似文献

This review focuses upon the applications of molecular structure calculations to determine the three-dimensional physicochemical features of polymeric solids. In some cases, the structure calculations are used to evaluate expressions arising from specific models or theories. As such, molecular structure calculations are auxillary aides in the illumination of the solid-state properties of polymers. 相似文献

Light transducing phycobiliproteins are encapsulated in optically transparent sol-gel matrices. Absorption and fluorescence spectroscopies are used to characterize the effect of the sol-gel encapsulation on the conformation and aggregation states of the three major phycobiliproteins present in phycobilisomes: phycoerythrin, phycocyanin, and allophycocyanin. It is found that the effects of sol-gel entrapment on the spectroscopic properties are significantly different for the three phycobiliproteins. The results indicate that phycoerythrin undergoes only minor change in its native structure when entrapped in sol-gel. However, significant changes in conformation and aggregation state occur when phycocyanin and allophycocyanin are entrapped in sol-gel matrices. A thin film of sol-gel encapsulated phycoerythrin is also coated on an optical fiber surface and strong fluorescence from the evanescent wave excitation is detected. The potential applications of sol-gel encapsulated phycobiliproteins in biosensors are discussed. 相似文献

A theory for the bound state of two plasmons in an electron gas is developed with the four-particle density response function invoking only the electron-electron interactions. The plasmon-plasmon interaction in our theory arises due to the exchange of four one-particle Green's functions for the electrons. This interaction is found to be attractive, and under certain conditions is reduced to the exchange of an electron-hole pair. However, this is not strong enough to bind two plasmons in the range of metallic densities, which is in contrast to the conclusions derived by Ruvalds et al. 相似文献
