A A cylindrical EPR cavity fitted with anti-Helmholtz coils and a PTFE sample holder. The test sample comprises two portions of DPPH powder separated by a 50 pm mylar film. . Japanese Journal of Applied Physics 2S L929.

A A DDS phase wheel. A signal from the frequency-fixed, phase-tunable

A A desktop NMR system using the OPENCORE NMR spectrometer and a

A A detailed model of the amino-terminal al The antiparallel arrangement of type IV molecules with alignment of cross-linking sites.

A A diagram describing the experimental setup for a magnetic-field cycling

A A diagram showing a normal and an abnormal negative component of the P wave in V1. When the product of the width in seconds by the height in millimetres of the negative mode exceeds in acute phase of myocardial

A A diagram showing the dependence of the energy levels of an unpaired electron in a nitroxide upon increasing applied magnetic field Bq. Arrows between the energy levels indicate transitions induced by electromagnetic radiation at a constant frequency. Three modes of motion that contribute to nitroxide dynamics. Adapted from ref. 14 with permission.

A A diffuser mounted as a tip on a fibre bundie aiiows uniform iiiumination aiong the probe axis restricts the illumination to a reduced angle.

A A dimeric coiled coil pdb identifier, 2zta An

A A disk with virtually no landmarks to indicate the future polarity of the embryo. , a short, squat, thickening of the blastoderm at the posterior marginal zone.

A A divalent ligand for the protein FK506 binding protein .

A A dry surfactant film, showing the hydrophilic head-groups dissolved in the aqueous phase and the hydrophobic chains extending into the gas phase. A wet surfactant, showing the bulk of the molecule dissolved in water and a few hydrophobic moieties in the gas phase.

A A electron density profile is shown for a 40 -thick organic film on a calcite surface. as a function of the momentum transfer along the surface normal direction. The period of the oscillations is directly related to the film thickness through AO In I..

A A fibre optic probe for Raman spectroscopy based on separate illumination and collection fibres. The output of the fibres is collimated and filtered and then projected onto the same area on the sample. Bandpass filters are used for the excitation fibres and longpass filters for the collection fibres. GRIN lenses are assembled into the probe in order to maintain small diameters. Adapted with permission from Myrick ML and Angle SM A fibre optic probe based on the design in

A A fibre optic probe for reflectometry. The light scattered from a single excitation fibre is detected by a linear array of collection fibres. Tilting the excitation fibre shifts the profile along the surface by an amount that is determined by the sample s optical properties. filters adapt the light intensity in a transfer array to a smaller dynamic range.

A A field showing two metaphase chromosome spreads horizontal lines showing the covers found during each line scan.

A A fluctuating interaction energy, V of zero and a mean

A A Fuei ceil CUP home Source

A A G plot of water . The higher

A A gas bubble in liquid and a drop in a gaseous environment. A liquid meniscus with radii of curvature of opposite sign between two solid cylinders.

A A gas electrode in general and a hydrogen electrode in particular

A A glass fiber reinforced LCP composite is shown to have interesting morphology. A polished thin section is shown in polarized light to exhibit a fine domain texture with some orientation of the polymer on the glass surfaces.

A A glass membrane electrode.

A A guanidinium grot i. B The three types of bonding motifs to a guanidinium moiety.

A A H magic-sandwich echo spectrum of a single crystal sample of 98.3 -
