Taxonomic results of the Bryotrop expedition to Zaire and Rwanda : 18., Calymperaceae
No full textThe first species list of the examined countries was published by Demaret (1940,1946) and the revision of the Syrrhopodon species of this area were made by Demaret and Leroy (1947). Further additional data were published on the basis of the collection of S. Lisowski (Orbán 1987). The tropical African species of the genera were revised by the Author (Orbán 1981) and later the key for the species was prepared by Orbán and Reese (1986). This key is suitable to identify practically all tropical African taxa, therefore I do not supply a key here for the 7 species collected in Central Africa. The world ranges of Syrrhopodon species was given by Reese (1987)
Plagiothecium lucidum (Hook. f. & Wils.) Paris in tropical Africa
No full textPlagiothecium lucidum (Hook. f. & Wils.) Paris is confirmed as a new addition to the bryoflora of tropical Africa on the basis of two collections from the Bale Mountains in Ethiopia. The type material of Isopterygium integrifolium Bartr. from Costa Rica in Central America is evaluated and this species is considered to be conspecific with P. lucidum. As a result of this taxonomic conclusion the range of this species is extended to Costa Rica and this is the first recognition of this species in the Central American isthmus. A world distribution map for this species is presented and some details of African plants and the type of I. integrifolium are illustrated
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]
No full textNewspaper article titled "Author Claims Evidence of Second JFK Assassin." The article states that author Richard J. Whalen concluded "that there is circumstantial evidence to support the theory of a second assassin in the shooting of President John F. Kennedy.
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Imipramine in dogs: A pharmacokinetic study following oral administration under fasted and fed conditions
No full textThis study investigates the pharmacokinetics (PK) of imipramine, a tricyclic antidepressant used in human psychiatric disorders and increasingly considered in veterinary medicine. Despite its longstanding use in canines, prior research on imipramine's PK in dogs is lacking. This study aimed to determine the PK of imipramine in dogs in regards to feeding conditions, and to ascertain whether desipramine (active metabolite) is formed or not. In this study, six male Labrador dogs underwent oral administration (1.5 mg/kg) of imipramine tablets (10 mg each; Tofranil®, Novartis) in both fasted and fed conditions. Dogs were randomly allocated to one of two treatment groups, employing an open, single-dose, two-treatment, two-phase, cross-over design, with a washout period of one week. Blood was drawn from the left cephalic vein to heparinized tubes at 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, 10, 24, and 48 h. Plasma concentrations were quantified using a validated HPLC method, and the data were analyzed using PKanalixTM software with a non-compartmental approach. Concentrations of imipramine remained quantifiable up to 1.5 hr after administration under both conditions. Desipramine, in both feeding states, was detectable for a short duration, but not quantifiable. No significant differences were observed in the PK parameters of imipramine between the fasting and fed states. The rapid attainment of maximum concentration (Cmax) occurred within 0.25 h, indicating a swift absorption rate. Notably, the terminal half-life in dogs was remarkably short at 0.25 h, prompting a re-evaluation of dosing strategies. Considering the recommended therapeutic plasma concentrations in humans, the administered dose might result in effective levels for a brief period of time. Future research should explore intravenous administration, multiple-dose studies, and metabolic investigations to further elucidate imipramine's PK in dogs
