As a result of considering the possibility of a similar mechanism in the flight orientation of bark and ambrosia beetles (Scolytidae) at times, a method by, which the human ...Type of Medium: Electronic ResourceURL: -

ISSN: 1432-072XSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Summary All of the three blue-green algae, Anabaena cylindrica, Mastigocladus laminosus and Nostoc muscorum are characterized by the presence of multi-layered envelopes (sheath, wall and plasma membrane), photosynthetic lamellae and a variety of intracellular granules. Sections of heterocysts of Anabaena cylindrica showed the presence of an internal membrane system as well as lamellae. An unusual feature of the structure of Nostoc muscorum was the presence of densely stained intracellular membranes or lamellae. The results emphasize the variability in appearance of the internal structure of the blue-green algae and point to the need for detailed investigations of the influence of change in physiological environment on the anatomy of these organisms.Type of Medium: Electronic ResourceURL: -

MnCl2 has been studied by X-ray diffraction in slowly cooled single crystals of NaCl doped with MnCl2. The relevance of these observations to other studies of esr, clustering and mechanical properties in this system is discussed.Type of Medium: Electronic ResourceURL: -

ISSN: 0006-3525Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: Electron microscopic autoradiographic observations on collagen fibrils grown in vitro allow growth rates in the N- and C-terminal directions to be measured on individual fibrils. Such observations, made on normal and iodinated collagen, show that normal fibrils grow at both ends (although rather more rapidly at the N-terminal end), whereas fully-iodinated collagen fibrils grow only at the N-terminal end.Measurements of growth rates at different temperatures provide estimates of the activation enthalpy (ΔH≠) and entropy (ΔS≠) of precipitation for the two types of collagen. Solubility measurements have also yielded values for the thermodynamic enthalpy (ΔH) and entropy (ΔS) of precipitation. Results show that the activated (rate-limiting) state is characterized by a large positive ΔH≠ and ΔS≠ similar in magnitude to the ΔH and ΔS of transition from solution to fibril. It is also concluded that the different rates of precipitation of normal and iodinated collagen cannot be explained in terms of fibril formation requiring ionization of the tyrosine residues.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
