Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
Determination of adrenaline and noradrenaline by resonance Raman spectrometry
(Elsevier, 1976-01)
Aminochromes of adrenaline and noradrenaline show resonance Raman scattering at 1480 and 1430 cm-1 respectively, with Ar+ excitation. Scattering intensity is a linear function of concentration. Detection limits are 1 x ...
Pyrolytic conversion of precursors prepared in Ti(NMe 2 ) 4 –diamine systems
(John Wiley & Sons, Ltd., 1998-10)
Precursors possessing Ti–N bonds were prepared by the reactions between Ti(NMe 2 ) 4 and each of three diamines H 2 NCH 2 CH 2 NH 2 , Me(H)NCH 2 CH 2 N(H)Me, HN(CH 2 CH 2 ) 2 NH (Ti(NMe 2 ) 4 :diamine 14= 141:2), and were ...
Focus on function: Single molecule RNA enzymology
(Wiley Subscription Services, Inc., A Wiley Company, 2007-12-05)
The ability of RNA to catalyze chemical reactions was first demonstrated 25 years ago with the discovery that group I introns and RNase P function as RNA enzymes (ribozymes). Several additional ribozymes were subsequently ...
Shape-selective separation of polycyclic aromatic hydrocarbons by reversed-phase liquid chromatography on tetraphenylporphyrin-based stationary phases
(Elsevier, 1993-07-02)
The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary ...
Effect of Dopants on Zirconia Stabilization—An X-ray Absorption Study: III, Charge-Compensating Dopants
(Blackwell Publishing Ltd, 1994-05)
Optically detected zero field magnetic resonance of phosphorous activated alkali halide crystals
(Elsevier, 1977-10-15)
Optically detected zero field magnetic resonance (ODMR) has been utilized to obtain the fine structure parameters |D| and |E| of the phosphorescent color center in phosphorous activated potassium chloride and bromide single ...
Decay characteristics of 84Se
(Elsevier, 1968-11)
The nuclide 84Se has been identified among the fission products of 235U. The selenium fraction was obtained by solvent extraction from HBr into 2,6-dimethyl-4-heptanone. The radiations were studied by [beta]- and [gamma]-ray ...
The illumination of molecular behavior by electron waves
(Elsevier, 1985-01)
Aspects of vapor-phase electron diffraction are discussed, singling out the seminal contributions of Yonezo Morino in collaboration with San-ichiro Mizushima and others. Recent developments leading to a precision approaching ...
The -ills of Educational Reform
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
Many instructors have sincerely accepted problem solving and critical thinking as instructional objectives. This kind of language, especially notions of the liberal-arts values of taking college classes, is used in compelling ...
