ORIGINAL RESEARCH Light Chain Amyloidosis: Patient Experience Survey from the Amyloidosis Research Consortium
No full textThe Author(s) 2015. This article is published with open access at Springerlink.com Introduction: Information detailing the experience of patients with light chain (AL) amyloidosis is lacking. The primary aim of this study was to gather data on the patient experience to understand the challenges i
Phillipsite at high pressure: a single-crystal X-ray synchrotron diffraction study
No full textPhillipsite is a low Si/Al natural zeolite, often found as autogenic mineral in both “close” and “open” hydrologic system or in vugs of basalt, as an alteration product of volcanic glass. Along with laumontite, it is one of the most common zeolites found in oceanic basalts. In order to investigate the high-pressure behavior of phillipsite and its structural evolution at the atomic scale, we performed an in situ single-crystal synchrotron X-ray diffraction experiment up to 10 GPa with a diamond anvil cell, using a nominally penetrating pressure-transmitting fluid (methanol:ethanol:H2O = 16:3:1 mix) (Gatta, 2010). The unit-cell parameters and the structure refinements within the P-range investigated show that: 1) phillipsite does not adsorb further H2O molecules from the penetrating-transmitting fluid within the P-range investigated; 2) the configuration of the extra-framework population changes with pressure (between 2 and 3 GPa), affecting the elastic behavior of the mineral. More in details, two distinct compressional regimes have been observed, in which the bulk moduli differs drastically (i.e., KV = 89(8) GPa between 0 and 2 GPa, KV = 18.8(7) GPa between 3 and 9 GPa); 3) phillipsite is crystalline at least up to 10 GPa, and this is surprising if we consider its microporous nature; 4) all the P-induced effects are completely reversible in decompression. The structural refinements allowed us to describe the mechanisms, at the atomic scale, that govern its elastic behavior, which are mainly governed by inter-tetrahedral tilting. The relatively low compressibility of phillipsite at room-P and its relatively wide P-stability shown in this experiment suggests that this zeolite is a potential H2O carrier during the first phase of the oceanic crust subduction or, toward the industrial front, its potential

Translator Training and Intercultural Competence
No full textThe object of this paper is to clarify what ‘intercultural competence’ actually entails for those learning to translate at university level, and will refer to a number of classroom activities that can successfully support the trainees during the learning.
Learning competences have been studied for over 50 years, and have recently been amplified through the ‘Dublin Descriptors’ as a result of university reform. Also, intercultural competences have been studied widely in the world of work. Yet, though the same competences are now deemed essential for translators there is little information on the sub-competences involved. Here, it is suggested that during the university first cycle, the cognitive learning competences could include first an understanding of self and other (cultural locatedness), then translation of culturebound
terms with a clear denotative reference, followed by connotative terms (linguaculture).
At this level, students would also learn how to apply relatively fixed communication patterns, having learned about preferred cultural writing styles and orientations. It is argued here that “self reflexive” thinking, should only be expected during the second cycle. Students at this level can more easily understand that text
meaning (and style) is negotiable according to context. Here, students also become more competent in the other metacognitive learning styles, and are more able to mindshift, change perceptual position and mediate. This will only be fully possible, however, when they are able to move away from the search for text-bound formal equivalence and learn to take risks (low uncertainty avoidance). It is asserted here that, to a large extent, this, and the other competences discussed, can be taught as part of translator training
C-Finite Sequences and Riordan Arrays
No full textMany prominent combinatorial sequences, such as the Fibonacci, Lucas, Pell, Jacobsthal and Tribonacci sequences, are defined by homogeneous linear recurrence relations with constant coefficients. These sequences are often referred to as C-finite sequences, and a variety of representations have been employed throughout the literature, largely influenced by the author’s background and the specific application under consideration. Beyond the representation through recurrence relations, other approaches include those based on generating functions, explicit formulas, matrix exponentiation, the method of undetermined coefficients and several others. Among these, the generating function approach is particularly prevalent in enumerative combinatorics due to its versatility and widespread use. The primary objective of this work is to introduce an alternative representation grounded in the theory of Riordan arrays. This representation provides a general formula expressed in terms of the vectors of constants and initial conditions associated with any recurrence relation of a given order, offering a new perspective on the structure of such sequences
Characterization of the new Malossi hydrothermal synthetic Emeral
No full textA new production of hydrothermal synthetic emeralds, grown in the Czech Republic with Italian technology, has been marketed since December 2004 with the trade name Malossi synthetic emerald. Several samples were investigated by standard gemological methods, combined with chemical analyses and UV-Vis-NIR and IR spectroscopy. A comparison of this material with natural and other synthetic emeralds (the latter grown by the flux and hydrothermal techniques) reveals that Malossi hydrothermal synthetic emerald can be identified on the basis of microscopic features and chemical composition, along with the mid-infrared spectrum

Endemic Aleyrodidae (Homoptera) and their parasites (Hymenoptera) on southern Vancouver Island, British Columbia
No full textFour species of whitefly (<i>Trialeurodes vaporariorum</i> (Westwood), <i>T. merlini</i> (Bemis), <i>Aleyrodes spiraeoides</i> Quaint., and <i>Aleyrodes</i> sp. A) were collected on native plants on southern Vancouver Island. Three species of parasite (<i>Encarsia</i> sp. (?formosa Gah.), <i>Euderomophale</i> sp. and <i>Amitus arcturus</i> Whitt.) were reared from these species. The possibility of using these parasites for biological control of <i>T. vaporariorum</i> in greenhouses is briefly discussed
