Characterization of five members of the actin gene family in the sea urchin
(Elsevier, 1981-12-28)
Hybridization of an actin cDNA clone (pSA38) to restriction enzyme digests of Strongylocentrotus purpuratus DNA indicates that the sea urchin genome contains at least five different actin genes. A sea urchin genomic clone ...
Excitation temperature, degree of ionization of added iron species, and electron density in an exploding thin film plasma
(Elsevier, 1981)
Time and spacially resolved spectra of a cylindrically symmetric exploding thin film plasma were obtained with a rotating mirror camera and astigmatic imaging. These spectra were decouvolved to obtain relative spectral ...
Similarities between stratum corneum basic protein and histidine-rich protein II from newborn rat epidermis
(Elsevier, 1981-03-27)
The stratum corneum basic protein and histidine-rich protein II were each isolated from newborn rat epidermis and compared by biochemical and immunologic methods. The proteins were indistinguishable by immunodiffusion using ...
Delivery of liposome membrane-associated sterols through silastic membranes
(Elsevier, 1981-08-05)
The transport of sterols incorporated into the lecithin bilayer of small unilamellar liposomes through a model membrane was studied. A two-chamber diffusion cell containing liposomes with incorporated [4-14C]cholesterol ...
Topology of NH2OH-induced Mn(II) release from chloroplast thylakoid membranes
(Elsevier, 1981-07-13)
Permeant and impermeant metal ion chelators have been used in conjunction with NMR relaxation time measurements (T1) of solvent protons to probe the membrane topology of the Mn(II) released from the water-oxidizing center ...
Emulsion stability--theoretical studies on simultaneous flocculation and creaming
(Elsevier, 1981-07)
A general dynamic equation is derived describing the behavior of a polydispersed emulsion in which Brownian flocculation, sedimentation-flocculation, and creaming are taking place simultaneously. The resulting equation ...
The stereochemistry of propylene-1,2-d2 epoxidation over silver catalysts
(Elsevier, 1981-07)
The stereochemistry of the epoxidation of cis-propylene-1,2-d2 to propylene oxide over three unsupported and one supported silver catalysts as well as over Ag2O and AgO was studied by microwave spectroscopy. Variations of ...
Electromagnetic effects in the Surface Enhanced Raman Scattering from a molecule at a liquid Hg surface
(Elsevier, 1981-09-02)
In a previous publication the image enhancement effect and the enhanced radiation due to near field excitation of surface roughness were calculated for a finite-size molecule above a metal described by a nonlocal dielectric ...
Calculated molecular structures and electronic spectra of the geometric isomers of a model carotenoid molecule, 6,11-dimethylhexadecaheptaene
(Elsevier, 1981)
The molecular structures and the electronic spectra of the geometric isomers of a model carotenoid polyene, 6,11-dimethylhexadecaheptaene, were calculated. It was concluded that solvent effects and conformational isomerization ...
