No concept in ecology has been more variously defined or more universally confused than ‘niche’.
El escultor del tiempo: claves de la “filosofía cinematográfica” de Gilles Deleuze
2018
Gilles Deleuze ha ofrecido en sus dos estudios sobre cine —L’image–mouvement y L’image– temps— una de las propuestas más ambiciosas de las últimas décadas en lo que concierne a la relación entre filosofía y cine, hasta el punto de construir una auténtica “filosofía cinematográfica” y de inaugurar, en paralelo a Stanley Cavell, una fructífera línea de investigación filosófica que ha dado en denominarse como “film–philosophy”. Su primera obra se centra, fundamentalmente, en elaborar una metafísica del tiempo inspirada en la filosofía de Henri Bergson, pero utilizando las posibilidades del cine para complementar y trascender las ideas del autor de L’évolution créatice. En su se…
Halothane inhibits endothelium-dependent relaxation elicited by acetylcholine in human isolated pulmonary arteries.
1997
This study examined whether a clinically relevant concentration of the volatile anaesthetic halothane modifies the endothelium-dependent relaxation produced by acetylcholine (3 nM-10 microM), histamine (1 pM-0.1 microM) and anti-human immunoglobulin E (1:1000) in human isolated pulmonary arteries submaximally precontracted with noradrenaline. An inhibitor of nitric oxide formation, N(G)-nitro-L-arginine (100 microM), attenuated acetylcholine-induced relaxation but failed to inhibit histamine- and anti-human immunoglobulin E-induced relaxation. Indomethacin (2.8 microM, a cyclooxygenase inhibitor) preferentially reduced the relaxation to histamine and anti-human IgE. Halothane (2%) significa…
Balamane: Variations on a Noisy Ground
2020
This contribution concentrates on a discussion of four conceptual keywords – Helmut, Sunglasses, Water, Language – which we explore as semiotic variations on a ground. This approach to the contradictory everyday realities of the touristic setting in Mallorca is the result of our (self-)critical reflections on how to write about language, migration, encounters, the normal and the liminal in the party tourism spot – and on how to give a (personal) insight into the world of contradictions at the Ballermann. We are considerably grateful to our research colleagues Angelika Mietzner and Janine Traber, with whom we have been working on the complex entanglements of tourism and migration since 2016 …
A precise measurement of the Z resonance parameters through its hadronic decays
1990
A measurement of the cross section for e+e-→ hadrons using 11 000 hadronic decays of the Z boson at ten different center-of-mass energies is presented. A three-parameter fit gives the following values for the Z mass MZ, the total width ΓZ, the product of the electronic and hadronic partial widths ΓeΓh, and the unfolded pole cross section σ0: MZ = 91.171 ± 0.030 (stat.) ± 0.030 (beam) GeV, ΓZ = 2.511 ± 0.065 GeV, ΓeΓh = 0.148 ± 0.006 (stat.) ± 0.004 (syst.) GeV2, σ0 = 41.6 ± 0.7 (stat.) ± 1.1 (syst.) nb, Good agreement with the predictions of the standard model is observed. From a two-parameter fit the number of massless neutrino generations is found to be Nv = 2.91 ± 0.26. Thus the hypothes…
Aesthetic perception of single implants placed in the anterior zone. A cross-sectional study
2016
Background: Several aesthetic indexes have been described to assess implant aesthetics. The aim of this study was to compare the aesthetic assessment made by dental professionals and students of single-tooth implants placed in the upper incisors. Material and Methods: A cross-sectional survey study using a subjective questionnaire to assess the aesthetics in 3 implant supported single-tooth cases in the anterior maxilla was performed. The interviewed subjects were divided into 4 groups: dentists with experience in implant treatment, dentists without experience in implants and 3rd and 5th year dental students. The questionnaire consisted of 2 visual analogue scales (VAS) to evaluate aestheti…
Intensity modulated radiation therapy with simultaneous integrated boost in early breast cancer irradiation. Report of feasibility and preliminary to…
2015
To investigate the feasibility and tolerance in the use of adjuvant intensity modulated radiation therapy (IMRT) and simultaneous integrated boost in patients with a diagnosis of breast cancer after breast-conserving surgery.Between September 2011 to February 2013, 112 women with a diagnosis of early breast cancer (T1-2, N0-1, M0) were treated with IMRT and simultaneous integrated boost after breast-conserving surgery in our institution. A dose of 50Gy in 25 fractions was prescribed to the whole breast and an additional dose of radiation was prescribed on the tumour bed. A dose prescription of 60Gy in 25 fractions to the tumour bed was used in patients with negative margins after surgery, w…
Orfeo Boselli e la “nobiltà” della scultura
2002
Orfeo Boselli, scultore, teorico e restauratore, non ha lasciato significativa traccia di sé in nessuno dei campi in cui ebbe modo di cimentarsi e persino delle sue vicende biografiche e della sua produzione artistica si hanno notizie frammentarie. Sebbene il suo nome compaia in diversi testi di critica d’arte, la sua figura scivola silenziosa nel panorama dell’estetica seicentesca e, a tutt’oggi, non esistono opere monografiche che valorizzino il ruolo, certamente non secondario, che questo scultore, considerato “minore” dagli storici dell’arte, svolse nel dibattito teorico del suo tempo. Le Osservazioni della scoltura antica si inseriscono nella tradizione avviata dai teorici del Quattroc…
Corticotomy-assisted orthodontics
2011
The use of orthodontic treatment in adult patients is becoming more common and these patients have different requirements specially regarding duration of treatment and facial and dental aesthetics. Alveolar corticotomy is an effective means of accelerating orthodontic treatment. This literature revision include an historical background, biological and orthodontic fundamentals and the most significant clinical applications of this technique. Orthodontic treatment time is reduced with this technique to one-third of that in conventional orthodontics. Alveolar bone grafting of labial and palatal/lingual surfaces ensures root coverage as the dental arch is expanded. Corticotomy-assisted orthodon…
Vertical gingival display changes associated with upper premolars extraction orthodontic treatment : a prospective clinical trial
2020
Background Extraction of upper bicuspids have been anecdotally blamed to increase the vertical gingival display (VGD) anteriorly. However, the extraction may be needed in some cases in order to correct the underlying orthodontic problem. Objectives: To investigate and compare vertical gingival display (VGD) changes associated with upper (first vs second) premolars extraction during orthodontic treatment. Material and Methods Design: A prospective clinical trial. Setting: Postgraduate dental teaching clinics at Jordan University of Science and Technology (JUST). Sample population: Sixty orthodontic patients were included in the study. They were treated with upper first or second premolars ex…
