T he two giants of the genus-that is so far as the cock birds are concerned, but, as with chiniana and a few others, their hens are so much smaller that even when in the field the two sexes are seen in company one may often doubt their being a pair of the same species.  相似文献

The B. O. C. Ruwenzori expedition of 1906 brought home a single immature female of this species, obtained in a papyrus swamp near Lake George, and to Ogilvie-Grant's discrimination we owe the recognition of its specific distinction from galactotes , the species it so closely resembles in coloration, and which is certainly carruthersi s nearest ally.  相似文献

A part from considerations as to where it is best wedged into the linear sequence, the brachyptera group is defined in general terms as a compact group of four small or very small species which resemble one another in many important specific characters and the other thirty-six species classified here as Cisticola in so many ways of form, coloration and behaviour as to make them best understood by classifying them also under that generic name.  相似文献

Abstract

On 23 February 1979 Sir Robert Falla collapsed and died at his home in Eastbourne. He was 77. His sudden death came as a great shock to his multitude of friends and colleagues, many of whom were still sharing with Sir Robert a deep sense of loss at the death on 31 May 1978, shortly after the couple's golden wedding anniversary, of his charming wife Molly.  相似文献

The least of all the Cisticolae—although some of the races of other species are as small—a tiny, roundabout little creature, scarcely bigger than a Goldcrest (Regulus) , and of not very different proportions: confined to a comparatively small part of East Africa. In life, quite "a Cisticola", but one with a good deal of individuality in its behaviour, with quick darting movements, and at home in fairly dry, tall "bush" country. Discovered only forty-five years ago, nana was classified without hesitation in its natural place among the Cisticolae, and there it has remained more or less undisturbed; although near relationship with Apalis angusticauda, a bird of very like coloration, but with a number of unlike characters of form, has been suggested.  相似文献

An easily recognized little bird in both of its very different seasonal dresses: one with no very near relative among the other species, but thoroughly Cirticoline from every point of view, alive or on the table: about the size of the Wood-Warbler (P. sibilatrix) , but with a shorter tail and much shorter wings, (totally different coloration), and in behaviour more like a bush-loving Sylvia , the Whitethroat (S. communis) for instance, only without any of that bird's aerial love-dances.  相似文献

The reproducibility of a V.A.C. (Vacuum Assisted Closure) instillation system was investigated by means of an in vitro model. The relation between the volume of a delivered solution and its removal from the system was studied in foams of various size. The relationship of instillation time periods and the volume of delivered solution was determined.  相似文献

First named in 1843 from a single specimen obtained by Dr. Andrew Smith's expedition. near the southern limit of its range, the South African bird, as one of the medium sized, pattern-backed Cisticolae may be said to have finally come into clear definition in Roberts' 1913 Review after a long period of endless confusion with some or all of the species of the subruficapilla group. But that does not entirely clear the ground for chiniana , for it is a remarkably plastic form in so far as coloration goes, and north of the Zambesi, particularly in equatorial East Africa, presents certain geographical variations of coloration which have tended towards confusing it with some of the plain-backed species of the genus.  相似文献

A previously undescribed species of Euglena, E. myxocylindracea, sp. nov., is described from soil in a garden and in a while pine woods in Pike County, Pa. In addition to the, type, an organism (No. 457) in the Culture Collection of Algae. Indiana University, hitherto designated E. viridis var. terricola. is transferred to E. myxocylindracea as var. terricola. Differences such as the usual absence of an emergent flagellum, or the presence of an extremely short one (ca. 3.5–4 μ), and the dominance of a palmelloid state in a variety of liquid and solid culture media in which the cells secrete dichotomously branching slimy cylinders distinguish the new species from E. viridis.  相似文献

Encephalitis is a challenging public health problem in Kern County and in the San Joaquin Valley area. During the last ten years the authors have studied the epidemiology of encephalitides due to arthropod-borne viruses and the methods used in the differential dignosis of these conditions. To incriminate a virus it is necessary to demonstrate a rise in antibody titer in the blood over a period of seven to fourteen days, the first specimen to be taken as soon as possible after onset of symptoms. A variety of tests may be necessary in some cases. Among the patients included in this presentation the greater number of those with encephalitis and also of those with poliomyelitis were under 30 years of age. The age range was five weeks to 49 years. The median annual mortality rate was 4.3 deaths per 100 cases for poliomyelitis and 3.9 for encephalitis. The greatest incidence occurred during the summer months.The clinical manifestations usually observed in encephalitis are described, but it is emphasized that wide variations and even completely atypical clinical phenomena are encountered. Four representative cases are reported and treatment is discussed. Vaccination and vector control are considered as the most promising means of combating the disease.  相似文献

A smallish, rather slender-built bird; quite a typical Cisticola like subruficapilla , which species despite its different coloration is-one of if not the nearest of its allies, about the same size, build and proportions as the Sardinian Warbler (S. melanocephala) and with much moreover in its behaviour which recalls that and other quite differently coloured bush-loving Sylvia Warblers, such as, for instance, the Whitethroat (S. communis).  相似文献

Recently the word P.A.D.A.M. has been proposed to replace the term Andropause (Partiel Andrologen Deficiency in Aging Males). This implies that most if not all problems of the aging male are due to testosterone déficiency, which is not at all true when one considers the results of endocrine investigations in that group. So many other sociological and relational causes are involved that the term P.A.D.A.M. is clearly a misnomer.  相似文献

The curricula vitae of four candidates for a professorial appointment at Athens University were examined to estimate the actual contribution of each candidate to the papers of which he was a coauthor. A total of 879 research papers by the four candidates were analysed in terms of the number of authors, the sequence of names, and the year of publication. The four authors presented 364, 349, 96, and 70 papers. If an equal contribution of all coauthors is assumed, the actual number of papers (all papers divided by the number of authors), is about 106, 83, 28, and 26, respectively, so that the rank of the four candidates did not change. On the assumption that the contribution was related to the candidate''s position in the order of the coauthors'' names, the numbers of papers were corrected to 84, 95, 26, 33 using one statistical method and to 88, 94, 28, 31 using another. These assumptions may not be valid, however, especially as the last author may be more important than the intermediate ones. It is suggested that the journals require authors to state their specific contribution to a paper, such as original idea, planning, collecting data, writing up, etc.  相似文献

Another of the more recently discovered North-east African species: not a very small bird, but about the size of the Whitethroat (Sylvia communis) and of not very different proportions, only the tail noticeably shorter: an inhabitant, for (he most part, of thorn-bush country, with manners, so far as they are known, more or less Sylvia-like.  相似文献

The inhibition of cytochrome c oxidase by cyanide, starting either with the resting or the pulsed enzyme, was studied by rapid-freeze quenching followed by quantitative e.p.r. It is found that a partial reduction of cytochrome oxidase by transfer of 2 electron equivalents from ferrocytochrome c to cytochrome a and CuA will induce a transition from a closed to an open enzyme conformation, rendering the cytochrome a3-CuB site accessible for cyanide binding, possibly as a bridging ligand. A heterogeneity in the enzyme is observed in that an e.p.r. signal from the cytochrome a3 3+-HCN complex is only found in 20% of the molecules, whereas the remaining cyanide-bound a3-CuB sites are e.p.r.-silent.  相似文献

The role and historical progress of n.m.r. applications in biochemistry are briefly outlined. Technical advances over the years have made n.m.r., at last, a technique which can give valuable information about a wide range of biochemical topics, from enzyme kinetics in vivo to the structure of protein-DNA complexes. Emphasis here is placed on studies of proteins, especially those made up from mosaics of modules. It is shown that n.m.r. can readily give detailed structural information about individual protein modules and that valuable information about the structure and function of the intact mosaic protein can be inferred.  相似文献

We determined the role of bird dispersal in seed and seedling dynamics of the tree Kalopanax pictus from 7 years of observing seed rain and seedling emergence in a broad-leaved deciduous forest in central Japan. We also performed an experiment on the influence of seed pulp on germination of seeds of K. pictus. Seeds of this species can lie dormant for several years, and this causes rather constant yearly seedling emergence in spite of irregular seed production. The spatial distribution of the seedlings that emerged each year (maximum distance from nearest conspecific seed-bearing tree of 90 m) was wider than that of gravity-dispersed seeds (max. distance of 37 m), suggesting seed dispersal by birds in winter. Emerged seedling densities at sites over 20 m from the nearest conspecific seed-bearing tree were highest in the spring of 1991, about half a year after the largest seed fall of the observation period. However, emerged seedling densities within 20 m from seed-bearing trees were highest in 1992, 1.5 years after the largest seed fall. These field observations may be explained by the experimental results on the effects of seed pulp on germination. Intact seeds germinate slowly at low germination rates, while seeds without seed pulp germinate quickly at high germination rates. Fallen seeds with seed pulp thus appear to form a seed bank near seed sources (temporal dispersal), while seeds scattered by birds appear to increase the possibility of reaching the present safe sites in distant areas with quick germination (spatial dispersal).  相似文献

Immunological studies of Fe-containing superoxide dismutase (FeSOD) and glutamine synthetase (GS) have established a close relationship betweenOceanospirillum linum (the type species of the genus),O. beijerinckii, Alteromonas communis, A. vaga, and two unnamed species of marine bacteria (groups H-1 and I-1). The four latter species have, consequently, been assigned to the genusOceanospirillum asO. commune comb. nov.,O. vagum comb. nov.,O. kriegii sp. nov. (group H-1; type strain 197, ATCC 27133), andO. jannaschii sp. nov. (group I-1; type strain 207, ATCC 27135). The phenotypic properties of these species are presented together with their distinguishing traits.  相似文献
