In situ external reflection infrared spectroscopy at the air-water interface was used to study the influence on phospholipid structure of an endogenous mixture of the two hydrophobic surfactant proteins, SP-B and SP-C, which are thought to play pivotal roles in the adsorption and function of pulmonary surfactant. Mixtures studied were 1:1, 2:1, and 7:1 (mol:mol) DPPC-d(62):DPPG, and 7:1 DPPC-d(...

We introduce Gutzwiller-correlated wave functions for the variational investigation of general multi-band Hubbard models. We set up a diagrammatic formalism which allows us to evaluate analytically ground-state properties in the limit of infinite spatial dimensions. In this limit recent results obtained within the Gutzwiller approximation are seen to become exact for these wave functions. We fu...

The transition frequencies of low-J excitation lines in the B1 + u − X1 + g , (v′, 0) Lyman bands have been measured for v′ = 2–18 and in the C1 u−X1 + g , (v′, 0) Werner bands for v′ = 0–4, using a narrow-band tunable extreme UV laser source at wavelengths λ = 92–105 nm in conjunction with the technique of 1 + 1′ two-photon ionization. The measurements can be divided into three categories for ...

Demonstration of remarkable biological effect of 3-deoxy-steroid confused the view about the mechanism of action of steroid,2) 3) while it has long been believed that the oxygen function at C-3 of steroid molecule is closely related to the mechanism of steroid action.1) 17a-Ethyny1-4-estrene-178-ol (ethynyl-estrenol) is one such compound which has no oxygen function at C-3 and shows remerkable ...

The striking difference in the cytochemical pattern of acid esterase between blood monocytes and T lymphocytes initiated the present study to determine whether or not the cytochemical difference is related to a cell-specific polymorphism of the isoenzymes. Enzyme assays and isoelectric focusing were performed using detergent-treated lysosomes from viable monocytes, granulocytes. T lymphocytes, ...

The molecular marker (SSR) has been used to investigate the markers associated with the agronomic traits including days to 50% flowering, tube ring time, days to maturity, plant height, the number of main stems per plant, the number of tubers per plant, dry matter content, main stem diameter, a single tuber weight, average single tuber weight, and the total yield in potato genotypes. Ten primer...

Availability of multispectral remote sensing data cheaply and its higher spectral resolution compared to remote sensing data with higher spatial resolution has proved valuable for geological mapping exploitation and mineral mapping. This has benefited applications such as landslide quantification, fault pattern mapping, rock and lineament mapping especially with advanced remote sensing techniqu...

Erianthus arundinaceus is not only a candidate plant for sugarcane breeding programs, but also a potential bioenergy grass. Genetic variation that is affected by geographic environments and ploidy level is very important for the utilization of Erianthus arundinaceus. In this study, effects of geographic environments and ploidy level on genetic variation were studied through analyzing the geneti...
