An analytical theory is proposed for the earth-atmosphere system at its equilibrium surface temperature, 289.16 K. A non-linear relation is formulated between atmospheric absorption and atmospheric radiation by modifying Kirchhoff's law on thermal radiation. For the first time, the Global Energy Balance can be realized in a wide range of atmospheri...

We have studied the interactions with neutral phospholipid bilayers of FPI, the 23-residue fusogenic N-terminal peptide of the HIV-1LAI transmembrane glycoprotein gp41, by CD, EPR, NMR, and solid state NMR (SSNMR) with the objective of understanding how it lyses and fuses cells. Using small unilamellar vesicles made from egg yolk phoshatidylcholine...

Crystals of [Cu{P(C5H4N)3}2]Br2·8H2O, studied at 173 K are triclinic, space group P, with unit-cell dimensions a= 9.082(4), b= 11.340(1), c= 9.084(2)Å, α= 98.40(4), β= 94.78(3), γ= 98.27(7)° and Z= 1; those of [Zn{P(C5H4N)3}2]Br2·8H2O studied at 293 K are monoclinic, space group C2/m with a= 12.506(6), b= 13.588(7), c= 11.593(7)Å, β= 101.62(4)° and...

Electron spin echo envelope modulation (ESEEM) is observed in a coal sample utilizing a two-pulse sequence originally proposed by Hartmann and Hahn to generate a ‘spin-locked echo’. It is experimentally shown that this spin-locked ESEEM (SLESEEM) is similar to three-pulse ESEEM rather than conventional two-pulse ESEEM with respect to the presence o...

Structural studies assessed interactions between the amino-terminal peptide (FP-I; 23 residues 519-541) of the glycoprotein 41 000 (gp41) of Human Immunodeficiency Virus Type-1 (HIV-1) and human erythrocyte membranes and simulated membrane environments. Peptide binding was examined at sub-hemolytic (approx. <5 μM) and hemolytic (≥5 μM) doses (Moble...

An explicit expression for the EPR absorption signal is presented as a two-variable function, S(B, ω), based on general theoretical and experimental grounds. Formulation of the lineshape function and the Boltzmann factor in S(B, ω) are reexamined by refining the description of the spin Hamiltonian of a system, which reveals a conceptual distinction...
