Black p-Branes versus black holes in non-asymptotically flat Einstein-Yang-Mills theory

We present a class of non-asymptotically flat (NAF) charged black p-branes (BpB) with p-compact dimensions in higher dimensional Einstein-Yang-Mills theory. Asymptotically the NAF structure manifests itself as an anti-de-sitter spacetime. We determine the total mass / energy enclosed in a thin-shell located outside the event horizon. By comparing the entropies of BpB with those of black holes in same dimensions we derive transition criteria between the two types of black objects. Given certain conditions satisfied our analysis shows that BpB can be considered excited states of black holes. An event horizon $r_{+}$ versus charge square $Q^{2}$ plot \ for the BpB reveals such a transition where $r_{+}$ is related to the horizon radius $r_{h}$ of the black hole (BH) both with the common charge $$Comment: 10 pages, 1 figure, updated version.

Non-abelian magnetic black strings versus black holes

We present $d+1-$dimensional pure magnetic Yang-Mills (YM) black strings (or $1-$branes) induced by the $d-$dimensional Einstein-Yang-Mills-Dilaton black holes. Born-Infeld version of the YM field makes our starting point which goes to the standard YM field through a limiting procedure. The lifting from black holes to black strings, (with less number of fields) is by adding an extra, compact coordinate. This amounts to the change of horizon topology from $S^{d-2}$ to a product structure. Our black string in $5-$dimensions is a rather special one, with uniform Hawking temperature and non-asymptotically flat structure. As the YM charge becomes large the string gets thinner to tend into a breaking point and transform into a $4-$% dimensional black hole.Comment: 5 pages no figure; Final version to appear in EPJ

Mapping the matrix: using compendium as a tool for recording the analytic group

This paper describes the application of Compendium, a knowledge cartography software tool, for the recording of group process. As a hypertext tool, it enables analysts to visualise connections between people, ideas and information, establishing an evidence base within and across contexts (such as group sessions). After customising its visual language, templates and keyword system, it has been piloted as a research tool for the measurement of group process. This would appear to hold the promise of providing a “digital substrate” for recording, discussing and analysing long term group dynamics in new ways. While the project is in its early stages, early indications are that it is a useful tool which can highlight group process and record change over time. In the longer term, it seems plausible that group processes such as multiple mirroring and identification, and such complex structures as the matrix, could be made visible and researchable through this methodology

Proton-proton bremsstrahlung below and above pion-threshold: the influence of the Δ\Delta-isobar

The proton-proton bremsstrahlung is investigated within a coupled-channel model with the $\Delta$ degree of freedom. The model is consistent with the $NN$ scattering up to 1 GeV and the $\gamma N\Delta$ vertex determined in the study of pion photoproduction reactions. It is found that the $\Delta$ excitation can significantly improve the agreements with the $pp \rightarrow pp\gamma$ at $E_{lab}=280$ MeV. Predictions at $E_{lab}=550$ and $800$ MeV are presented for future experimental tests.Comment: 26 pages Revtex, 12 figures are available from the authors upon request ([email protected]

Fair Wind: Medicine and Consolation on the Berens River

Fair Wind (Naamiwan) was an Ojibwa healer and leader widely known along the Berens River of Manitoba and northwestern Ontario in the early to mid-twentieth century. In the 1930s he became acquainted with the American anthropologist, A.Irving Hallowell, whose writings and photographs first drew our attention to Fair Wind's life and to the significance of his distinctive drum ceremonial, the roots of which extended to the Drum Dance that originated in Minnesota in the 1870s. This paper traces his life and explores the nature of his religious leadership, drawing upon the recollections of his descendants as well as on the records left by Hallowell and the numerous fur traders, missionaries, and others who visited the region during his long lifetime ( 1851-1944).Au cours de la première moitié du vingtième siècle, la réputation de l'Ojibwa Fair Wind (Naamiwan), guérisseur et chef spirituel vivant le long de la rivière Berens, qui s'écoule entre le Manitoba et le nord-ouest de l'Ontario, prit un un essor considérable. C'est dans les années 1930 qu'il fit la connaissance de l'anthropologue américain A. Irving Hallowell dont les écrits et les photographies attirèrent pour la première fois notre attention sur sa vie et sur la signification d'un rituel du tambour particulier, originaire du Minnesota des années 1870s. Ce portrait de la vie de Fair Wind utilise les souvenirs de ses descendants de même que les notes laissées par Hallowell, par les nombreux missionnaires, trafiquants de fourrures, et autres personnes qui visitèrent la région durant sa longue vie (1851-1944) pour étudier la nature de son autorité religieuse

Bowhead whales, and not right whales, were the primary target of 16th- to 17th-century Basque Whalers in the Western North Atlantic

During the 16th and 17th centuries, Basque whalers travelled annually to the Strait of Belle Isle and Gulf of St. Lawrence to hunt whales. The hunting that occurred during this period is of primary significance for the North Atlantic right whale, Eubalaena glacialis (Müller, 1776), because it has been interpreted as the largest human-induced reduction of the western North Atlantic population, with ~12250–21 000 whales killed. It has been frequently reported that the Basques targeted two species in this region: the North Atlantic right whale and the bowhead whale, Balaena mysticetus L., 1758. To evaluate this hypothesis and the relative impact of this period of whaling on both species, we collected samples from 364 whale bones during a comprehensive search of Basque whaling ports from the 16th to the 17th century in the Strait of Belle Isle and Gulf of St. Lawrence. Bones were found and sampled at 10 of the 20 sites investigated. DNA was extracted from a subset (n = 218) of these samples. Analysis of the mitochondrial cytochrome b region identified five whale species. The identification of only a single right whale bone and 203 bowhead whale bones from at least 72 individuals indicates that the bowhead whale was likely the principal target of the hunt. These results imply that this whaling had a much greater impact (in terms of numbers of whales removed) on the bowhead whale population than on the western North Atlantic right whale population.Aux XVIe et XVIIe siècles, les baleiniers basques se rendaient tous les ans au détroit de Belle Isle et au golfe du Saint- Laurent pour faire la chasse aux baleines. La chasse qui s’est effectuée pendant cette période revêt une grande importance pour la baleine franche ou baleine noire de l’Atlantique Nord, Eubalaena glacialis (Müller, 1776), car cette activité serait interprétée comme la plus grande réduction de la population de baleines franches de l’Atlantique Nord causée par l’être humain, au rythme d’environ 12 250 à 21 000 baleines tuées. On a souvent signalé que les Basques visaient deux espèces dans cette région, soit la baleine franche de l’Atlantique Nord et la baleine boréale, Balaena mysticetus L., 1758. Pour évaluer cette hypothèse et l’incidence relative de cette période de pêche aux baleines sur ces deux espèces, nous avons recueilli des échantillons provenant de 364 ossements de baleines dans le cadre d’une recherche approfondie de ports basques de chasse à la baleine remontant aux XVIe et XVIIe siècles dans le détroit de Belle Isle et le golfe du Saint-Laurent. Des ossements ont été trouvés et échantillonnés à 10 des 20 sites ayant fait l’objet de notre recherche. De l’ADN a été extrait d’un sous-ensemble (n = 218) de ces échantillons. L’analyse mitochondriale cytochrome b de la région a permis d’identifier cinq espèces de baleines. L’identification d’un seul os de baleine franche et de 203 os de baleines boréales provenant d’au moins 72 individus laisse croire que la baleine boréale était probablement la cible principale des chasseurs. Ces résultats impliquent que la chasse à la baleine a eu des incidences beaucoup plus grandes (en termes de nombres de baleines éliminées) sur la population de baleines boréales que sur la population de baleines franches de l’ouest de l’Atlantique Nord

Asking visitors to help: research to guide strategic communication in protected area management

Central to the mission of most protected areas is managing visitor use in such a way that visitor experiences are enhanced while fragile environments are protected. Protected area management agencies annually devote significant financial and human resources to repairing biological and physical damage resulting from uninformed visitor behaviour. Resources do not exist in most agency budgets to provide adequate personnel to monitor and manage visitor behaviour directly, particularly in large or remote areas. To the extent managers are able to harness communication to persuade visitors to voluntarily behave properly in protected areas, significant benefits will accrue both to budgets and to resource protection. Over the long term, millions of dollars that would otherwise be devoted to mitigating visitor-induced impacts could be saved or redirected to other operational priorities such as improving access and visitor services
