A Reinvestigation of Cross-sections of Cilia
The cilium was one of the first cell organelles to be investigated with the electron microscope (see Manton and Clarke, 1952; Fawcett and Porter, 1954). Since then, this structure has been widely reinvestigated as improved techniques became available both to the electron microscopist and to the biochemist. In the study reported here, improvements in fixation and the use of the "Markham" rotatio...
متن کاملCompetitive suppression of Quercus douglasii (Fagaceae) seedling emergence and growth.
Reduced recruitment of blue oak (Quercus douglasii) seedlings in California grasslands and woodlands may result from shifts in seasonal soil water availability coincident with replacement of the native perennial herbaceous community by Mediterranean annuals. We used a combination of container and field experiments to examine the interrelationships between soil water potential, herbaceous neighb...
متن کاملA Reinvestigation of a Superhard Tetragonal sp3 Carbon Allotrope
I 4 ¯ -carbon was first proposed by Zhang et al., this paper will report regarding this phase of carbon. The present paper reports the structural and elastic properties of the three-dimensional carbon allotrope I 4 ¯ -carbon using first-principles density functional theory. The related enthalpy, elastic constants, and phonon spectra confirm that the newly-predicted I 4 ¯ -carbon is thermodynami...
متن کاملReinvestigation of KMg1/3Nb2/3OPO4 1
The crystal structure of potassium magnesium niobium oxide phosphate, KMg(1/3)Nb(2/3)OPO(4), which was described in the space group P4(3)22 [McCarron & Calabrese, (1993 ▶). J. Solid State Chem.102, 354-361], has been redetermined in the revised space group P4(1). Accordingly, the assignment of the space group P4(3)22 and, therefore, localization of K at a single half-occupied position, as noted...
متن کاملReinvestigation of direct proton decay of Sb
The isotope Sb is known as the lightest ground state proton emitter [1]. In an experiment performed at Berkeley [2], a 478±15 keV proton line was reported and assigned to the the proton emission from the spherical πd5/2 orbital in Sb. As the experimental technique used in this experiment, namely a helium-jet system, did not allow for background suppression, the proton energy spectrum contained ...
