A and S enantiomers of 2-ethyloxirane. Comparison of spectra obtained by FT with uniform sampling, covariance with uniform sampling, and covariance with nonuniform sampling. Reprinted with

A and show H spectra recorded at 500 MHz of a solution of 4-methoxy indole in 50

A and showing evolution of the stent over the years

A and shows the time dependence of skin tumor formation in the groups treated with DMBA TPA, with or without 0.2 pM each of three lanostanes, pachymic acid . The first tumor appeared at week 11 in the group treated with DMBA TPA. In the groups treated with DMBA TPA and 59, 51, and 64, the first tumor appeared at week 13, 14, and 13, respectively. The percentage of tumor-bearing mice treated with DMBA TPA was 73 at week 20, whereas the percentages in the groups

A and surfaces as a function of Lriu

A and while for anions ApH 10-90 2 pH units is commonplace. Uptake of some anions is very little sensitive to the pH, and such uptake curves are not s-shaped, but the uptake nearly linearly decreases with the pH

A and y2 relationship for typical heavy-fermion compounds, including semi-heavy fermion compounds .

A andB Breast carcinoma, in a core biopsy of a patient, pretreatment. Hematoxylin-eosin H E, magnification x400.

A Andersen eight-stage nonviable inertial sampler. Four-stage liquid impinger.

A Anderson s double-stranded porphyrin ladder and .

A Anderson s zinc porphyrin—pyridine complex which has a very high binding affinity .

A Angular distribution of the intensity . Zq, 6 at the location Zq 3 cm within the one-dimensional photobioreactor from

A Anion exchange separation of TCO4 and RcOii. Dowex 1-X4, ClO.i form, column eluted with D.l M NH4CIO4 .

A Anisotropy of mandelic add in the presence of -cyclodextrin as a function of solution pH. Ratio of anisotropy values and selectivity as a function of pH. Ratios and selectivities less than one indicate reversal of preferential binding. Reproduced with permission from Ref. .

A anmetric qrnthesis of a-aUcyl a-amino acids and Cl-allgrlated THIQs. THF tetrahydrofuran.

A Annihilation coincidence and single-photon detection.

A Anodized alumina, posted microreactor used for reforming of ammonia to hydrogen.

A Anomalous origin of LAD from a very big RCA. The LAD makes a loop and presents a long stenosis responsible for exercise anginal pain. The basal ECG was practically normal but during exercise test the patient presents ST-segment depression and angina.

A ANOP analysis 1, of representative taxa of the major groups of rhynchonellates.

A Anteroposterior chest radiograph of a 33-year-old patient with subacute HP showing diffuse ground-glass attenuation. Bird-related chronic HP. Chest radiograph shows shortening of the lung fields, diffuse reticulonodular opacities, and signs of pulmonary arterial hypertension. Abbreviation

A Anthracite starting material far test carbonization in dilatometer. Anthracite heated in dila-tometer to 505 C. Magnification 110 X, oil immersion

A Antibody 1D4 catalyzes a disfavored. yn-ebmination reaction, Antibody 26D9 catalyzes a difavored 6-endo-

A Antibody 28F11 catalyzes Gly-Plie bond cleavage. The hapten is a stable cobalt Antibody 38G2

A Antibody 43C9. elicited against a phosphonamidate hapten, catalyzes the hydrolysis of an activated amide. Evidence reveals that antibody 43C9 employs a covalent catalytic mechanism. HisL91 is the nucleophile that attacks the substrate s amide carbonyl. Residue HisH35 assists in transition-state stabilization, while Trj L36 and TryH95 are probably involved in proton transfer.
