For the reaction M(+)(C(2)H(4))(n-1) + C(2)H(4) --> M(+)(C(2)H(4))(n), where M = Ag, Au, the binding energies are predicted at the second order perturbation (MP2) and coupled cluster (CCSD(T)) levels of theory. As the basis set is systematically improved, the predicted M = Ag binding energies steadily improve, as compared to the experimental values. In fact, the complete basis set limit (CBS) p...

Immunocytochemistry was used for the direct measurement of cyclobutane pyrimidine dimers, (6-4) photoproducts, and Dewar isomers in normal human mononuclear cells following irradiation by natural sunlight or by a FS20 broad spectrum UVB sunlamp. The induction of each type of photoproduct was detected following 30-60 min sunlight exposure or with FS20 fluences as low as 50-100 Jm-2. With increas...

The plasminogen activator content in the circulating blood has hitherto been thought to derive largely from the endothelium of the veins (Messer, Celander, and Guest, I962; Chakrabarti, Birks, and Fearnley, I963; Warren, I964), though this has been difficult to prove and several other hypotheses have been put forward. Pandolfi and his colleagues (i967), for instance, believe that the plasminoge...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...
