OBJECTIVE
To assess the prognostic role of multidetector computed tomography coronary angiography (MDCT-CA) in patients with diabetes with suspected coronary artery disease (CAD). Use of MDCT-CA is increasing in patients with suspected CAD. However, data supporting its prognostic value in patients with diabetes are limited.

RESEARCH DESIGN AND METHODS
Between January 2006 and September 2007, 429 consecutive diabetic patients were prospectively studied with MDCT-CA for detecting the presence and assessing the extent of CAD (disease extension and coronary plaque scores). Patients were classified according to the presence of normal coronary arteries and nonobstructive (&lt;50%) and obstructive (≥50%) coronary lesions. The composite rates of hard cardiac events (cardiac death, nonfatal myocardial infarction, unstable angina) and all cardiac events (including revascularization) were the end points of the study.

RESULTS
Twenty-four patients were excluded because MDCT-CA data were not able to be interpreted. Of the remaining 405 patients, clinical follow-up (mean 62 ± 9 months) was obtained in 390 (98%). Multivariate analysis showed that predictors of hard and all events were obstructive CAD, three-vessel CAD, and left main coronary artery (LMCA) disease. Cumulative event-free survival was 100% for hard and all events in patients with normal coronary arteries, 78% for hard events and 56% for all events in patients with nonobstructive CAD, and 60% for hard events and 16% for all events in patients with obstructive CAD. Three-vessel CAD and LMCA disease were associated with a higher rate of hard cardiac events.

CONCLUSIONS
MDCT-CA provides long-term prognostic information for patients with diabetes with suspected CAD, showing excellent prognosis when there is no evidence of atherosclerosis and allowing risk stratification when CAD is present.

OBJECTIVE
Roux-en-Y gastric bypass (RYGB) in humans can remit type 2 diabetes, but the operative mechanism is not completely understood. In mice, fibroblast growth factor (FGF) 15 (FGF19 in humans) regulates hepatic bile acid (BA) production and can also resolve diabetes. In this study, we tested the hypothesis that the FGF19–BA pathway plays a role in the remission of human diabetes after RYGB surgery.

RESEARCH DESIGN AND METHODS
Cohorts of diabetic and nondiabetic individuals of various body weights were used. In addition, RYGB patients without diabetes (No-Diabetes), RYGB patients with diabetes who experienced remission for at least 12 months after surgery (Diabetes-R), and RYGB patients with diabetes who did not go into remission after surgery (Diabetes-NoR) were studied. Circulating FGF19 and BA levels, hepatic glycogen content, and expression levels of genes regulating the FGF19–BA pathway were compared among these groups of patients using pre- and postoperative serum samples and intraoperative liver biopsies.

RESULTS
Preoperatively, patients with diabetes had lower FGF19 and higher BA levels than nondiabetic patients, irrespective of body weight. In diabetic patients undergoing RYGB, lower FGF19 levels were significantly correlated with increased hepatic expression of the cholesterol 7alpha-hydroxylase 1 (CYP7A1) gene, which modulates BA production. Following RYGB surgery, however, FGF19 and BA levels (particularly cholic and deoxycholic acids) exhibited larger increases in Diabetic-R patients compared with nondiabetic and Diabetic-NoR patients.

CONCLUSIONS
Taken together, the baseline and postoperative data implicate the FGF19–CYP7A1–BA pathway in the etiology and remission of type 2 diabetes following RYGB surgery.
Palaeobotanical studies on Late Glacial and Holocene vegetation development and transformations of the ‘Wielkie Błoto’ mire near Gołdap (north-eastern Poland)

Published: June 2013

ABSTRACT
This paper presents the results of palynological, macrofossil and peat analyses that were conducted on deposits from a profile collected from the Wielkie Błoto mire near Bałupiany (north eastern Poland). The investigation revealed that the recorded changes of vegetation span the period from the decline of the Younger Dryas (ca 9600 cal. yr BC) to the late Subboreal or early Subatlantic chronozone, but due to a 40 cm long sediment gap a complete reconstruction was not possible. At the beginning, the area was occupied by steppe and tundra communities together with abundant Juniperus stands. A subsequent expansion of birch (Betula) woodlands with pine (Pinus sylvestris) took place in the Preboreal chronozone in which a rise in the water level and/or basin deepening was recorded at the site as well. The domination of such woodlands lasted to the end of the Boreal chronozone when Corylus avellana expanded rapidly. In the Atlantic chronozone multispecies deciduous forests developed with Tilia cordata and Quercus, while Ulmus together with Alnus spread in damp habitats. During this chronozone, traces of the occurrence of Carpinus betulus were detected in the macrofossil analysis, while the pollen analysis failed to record its presence. The expansion of Carpinus betulus and Picea abies was characteristic of the Subboreal chronozone when both taxa presented antagonistic optima. Alone in north-eastern Poland, there was a re-expansion of deciduous forest in the younger part of the Subboreal chronozone caused probably by low human impact, which is reflected in the whole profile. The first probable traces of human activity were noticed in the Atlantic chronozone and attributed to peoples of the Mesolithic or Early Neolithic cultures, while the first evidence of cultivation was correlated to the Bronze Age. However, the low resolution of the radiocarbon dates did not allow a more precise reconstruction of the chronology. The analysis of macrofossils and tissues indicated two episodes of oligotrophication of the mire. The first one took place during the Boreal chronozone, while the second fall in trophy was triggered by spruce expansion in the Subboreal chronozone. On the other hand, a rise in human impact during the first Carpinus betulus maximum caused eutrophication of the mire.
Measurement of the maximum value of non-uniform strain using a temperature-insensitive fibre Bragg grating method
Authors: Kisała P. 
Published: June 2013

AbstractThis paper presents an optoelectronic method for measuring the maximum value of non-uniformly distributed strain at varying temperature. Use of conjugate a gradient algorithm and a sensor model makes it possible to determine the maximum non-uniform strain value and the temperature at which the measurement is performed. The described sensor system enables the maximum strain value to be determined with a linear resolution of 0.003 m. A specially designed measurement system is proposed to verify the plausibility of using uniform fibre Bragg gratings for the simultaneous measurement of two quantities. The possibility of using the spectrum of two grating sensors to determine the maximum value of a non-uniform distribution of strain and temperature values is demonstrated.

Authors: Naumowicz M. , Melosik M. , Katarzynski P. , Handkiewicz A. 
Published: June 2013

AbstractThe paper illustrates a practical example of technology migration applied to the colour space converter realized in CMOS technology. The element has analogue excitation and response signals expressed in current mode. Such converter may be incorporated into an integrated vision sensor for preconditioning acquired image data. The idea of a computer software tool supporting the automated migration and design reuse is presented as the major contribution. The mentioned tools implement the Hooke-Jeeves direct search method for performing the multivariable optimization. Our purpose is to ensure transferring the circuit between usable fabrication technologies and preserving its functional properties. The colour space converter is treated as the case study for performance evaluation of the proposed tool in cooperation with HSPICE simulation software. The original CMOS technology files for Taiwan semiconductor (TSMC) plant were utilized for the research. The automated design migration from 180 nm into 90 nm resulted with obtaining compact IC layout characterized by a smaller area and lower power consumption. The paper is concluded with a brief summary that proves the usability of the proposed tool in designing CMOS cells dedicated for low power image processing.

AbstractThe paper describes practical application of pulsed microchip laser generating at 1535-nm wavelength to a laser rangefinder. The complete prototype of a laser rangefinder was built and investigated in real environmental conditions. The measured performance of the device is discussed. To build the prototype of a laser rangefinder at a reasonable price and shape a number of basic considerations had to be done. These include the mechanical and optical design of a microchip laser and the opto-mechanical construction of the rangefinder.
Direct excitation of the Tamm plasmon-polaritons on a dielectric Bragg reflector coated with a metal film

Published: June 2013

AbstractTamm plasmon-polariton is a surface state or surface wave formed at the boundary between a metal and a dielectric Bragg reflector. In order to directly excite the Tamm plasmon-polaritons with unit transmission, we design a structure of Bragg reflector coated with a metal film. Through the Bloch theorem of periodic structures and transfer matrix method, we deduce the existence conditions of the Tamm plasmon-polaritons. For a a finite structure, the Tamm plasmon-polaritons can be excited, which is dependent on the thickness of metal, the period number of the Bragg reflector, the incident direction and frequency. On proper conditions, a perfect transmission for the Tamm plasmon-polariton mode can be achieved without the use of attenuated total reflection prism coupling or diffraction grating.
Les études en prison : les paradoxes de l'institution carcérale
Authors: Salane Fanny 
Published: June 2013

Cet article se propose de cerner la place de l’école en prison. La place symbolique et juridique tout d’abord, à partir de l’étude de textes officiels, qui mettent en avant l’éducation comme un droit. La place effective ensuite, à partir d’entretiens menés avec des « détenus-étudiants ». La confrontation de ces deux discours permet de souligner les paradoxes de l’institution carcérale, qui arrive difficilement à concilier ses différentes missions. En prison, la logique sécuritaire et disciplinaire prime toujours sur la logique scolaire, transformant bien souvent le droit à l’accès à l’éducation en privilège.
La déconstruction et le problème de la vérité
Authors: Mary François 
Published: June 2013

Cet article vise à exposer et à examiner la conception de la vérité chez Derrida. Pour ce faire, nous proposerons une rapide définition de la déconstruction dans son ensemble (I). Cette présentation permettra de comprendre, d’une part, la critique derridienne de la vérité comme logos (c’est-à-dire comme une pièce essentielle de la « métaphysique ») (II), mais aussi, d’autre part, l’approche plus positive dont ce concept fait progressivement l’objet, aboutissant à l’idée d’une vérité performative et pragmatique, liée notamment au concept de témoignage (III). Enfin, nous essaierons de montrer que le problème de la vérité révèle une tension entre deux strates de discours qui divisent la déconstruction dans son ensemble, et dont on peut interroger l’homogénéité (IV).
La phénoménologie bien tempérée
Authors: Thomas-Fogiel Isabelle 
Published: June 2013

Cet article se propose d’analyser le dernier livre de Jean-Yves Lacoste, Être en danger , pour le situer dans le champ plus vaste de la phénoménologie aujourd’hui et ainsi mettre en lumière ses apports spécifiques. L’article montre comment la thèse principale du livre (selon laquelle l’être ne se dit que par ses modes, éclats ou fragments, qui ne pourront jamais s’hypostasier en une chimérique totalité) relativise la question de « l’être en tant qu’être » comme visée ultime de la philosophie (différence d’avec Heidegger), sans pour autant abandonner la question de l’être (différence d’avec Levinas ou Marion). Cette thèse centrale implique une transformation significative de certains présupposés de la phénoménologie la plus actuelle. Trois traits originaux de l’entreprise de Lacoste sont, par là, explicités : 1) sa reconsidération du donné dans une phénoménologie de la fragilité plutôt que de l’excès ; 2) sa réhabilitation de la présence et d’une certaine forme d’intériorité ; 3) enfin, et surtout, son élaboration d’une nouvelle relation à l’histoire et à la tradition, résultat de son refus de « l’histoire de l’être » et de la prétendue « structure ontothéologique de la métaphysique », lieu commun de bon nombre de phénoménologies.

Authors: Hashemi Hassan , Khabazkhoob Mehdi , Peyman Alireza , Miraftab Mohammad , Jafarzadehpur Ebrahim , Emamian Mohammad Hassan , Shariati Mohammad , Fotouhi Akbar 
Published: June 2013

PURPOSE:
To examine the relationship of spherical equivalent (SE) with refractive, corneal, and residual astigmatism.

METHODS:
Using stratified cluster sampling, 6,311 individuals were invited and 82.2% participated in this study. Examinations including uncorrected and corrected distance visual acuity tests, refraction, slit-lamp examination, and funduscopy were performed for all participants. Refraction and keratometry were used to calculate refractive and corneal astigmatism, respectively, and their difference was regarded as residual astigmatism.

RESULTS:

Refractive astigmatism showed a U-shaped relationship with SE; with every diopter (D) increase in astigmatism, the SE increased by 0.230 D in hyperopes and 0.664 D in myopes (
P
< .001). With every 1.0 D increase in residual astigmatism, the SE showed 0.376 D myopic shift in myopes (
P
= .004) and 0.077 D hyperopic shift in hyperopes (
P
= .224). Mean SE was highest among cases of with-the-rule (WTR) astigmatism (
P
< .001). Cases of high myopia and high hyperopia mostly had WTR and most emmetropes had against-the-rule (ATR) refractive astigmatism. Residual astigmatism was mostly WTR in emmetropic cases; at higher levels of SE error in myopes and hyperopes, WTR residual astigmatism decreased, whereas ATR and oblique residual astigmatism increased.

CONCLUSIONS:
Increases in SE are associated with higher levels of refractive and residual astigmatism among myopic and hyperopic cases. Unlike refractive astigmatism, WTR residual astigmatism was mostly seen in near emmetropic individuals.

Visión y construcción del espacio en la Chronica Adefonsi Imperatoris
Authors: Reglero de la Fuente Carlos Manuel 
Published: June 2013

La visión de la Chronica Adefonsi Imperatoris opone dos espacios políticos y religiosos: la “tierra de los cristianos” y la “tierra de los musulmanes”. Estos se corresponden con el imperio de Alfonso VII y el de los almorávides, que se proyectan fuera de la Península Ibérica, hacia el sur de Francia y el Magreb respectivamente. El cronista se interesa además por el Mediterráneo, aunque lo conoce mal. La “tierra de los cristianos” se articula en torno a reinos, entendidos como territorios sobre los que un rey ejerce su poder, que cuentan con fronteras definidas, y con unos polos o centros desde donde se ejerce dicho poder (León, Toledo). El frecuente empleo de corónimos como Castilla, Galicia o Extremadura, ofrece una visión de la diversidad interna del reino y de su articulación regional.
La Sibylle au miroir des Anciens comme reflet de l’image de la Modernité dans l’Auto de la Sibila Casandra de Gil Vicente (début XVIe s.)
Authors: Canonica Elvezio 
Published: June 2013

La communication se propose d’explorer le traitement de la figure de la Sibylle dans une représentation religieuse de Gil Vicente, un dramaturge portugais bilingue du début du XVIe siècle, composée en espagnol : l’Auto de la Sibila Cassandra, une œuvre dont les personnages (Sibylles et prophètes) sont des bergers. Il s’agit du réemploi d’un modèle antique (celui de la Sibylle de Cumes, en particulier) et de la récupération d’une thématique païenne dans une perspective chrétienne, en accord avec la représentation navideña. La Sibylle Cassandre, étant convaincue, d’après une prophétie, d’être celle qui a été choisie pour être la mère du Christ, refuse toute proposition de mariage, notamment celle de Salomon. Par ce personnage, Gil Vicente établit un lien avec le Cantique des cantiques et montre a contrario une attitude critique envers l’Église de son temps.
The Poor as Suppliers of Intellectual Property: A Social Network Approach to Sustainable Poverty Alleviation
Authors: Shivarajan Sridevi , Srinivasan Aravind 
Published: June 2013

ABSTRACT:We extend the Base of the Pyramid (BoP) poverty-alleviation approach by recognizing the poor as valuable suppliers—specifically of intellectual property. Although the poor possess huge reserves of intellectual property, they are unable to participate in global knowledge networks owing to their illiteracy and poverty. This is a crippling form of social exclusion in today’s growing knowledge economy because it adversely affects their capabilities for advancement at several levels. Providing the poor access to global knowledge networks as rightful participants—as suppliers of intellectual property—leads to poverty alleviation as a result of their increased social inclusion, not only through economic benefits, but also through the poor’s improved well-being as a result of their increased self-esteem and dignity. Using concepts from social network theory, we develop a poverty-alleviation approach to harness and integrate the intellectual property of the poor into global knowledge networks through trust-based partnerships among the poor, non-governmental organizations, and multinational corporations.

Published: June 2013

Nous décrivons ici le processus de mise à l’essai de deux nouvelles méthodes d’enseignement de la compréhension en lecture destinées aux lecteurs débutants de milieu défavorisé. Dans l’étude 1, six classes de deuxième année du primaire ont été assignées à l’une de trois conditions : contrôle (enseignement régulier seulement), vocabulaire ou stratégie. Bien que les élèves des conditions intervention aient réalisé des apprentissages, ces gains ne se sont pas transférés aux mesures de compréhension. Dans l’étude 2, nous avons testé une version modifiée des méthodes d’enseignement en utilisant un schème similaire à celui de l’étude 1. Les résultats de l’étude 2 suggèrent que les méthodes d’enseignement sont suffisamment prometteuses pour évaluer leur efficacité de manière formelle.
Obligate exudativory characterizes the diet of the pygmy slow loris Nycticebus pygmaeus
Authors: Starr Carly , Nekaris K.A.I. 
Published: June 2013

AbstractFew primate species are known to excavate plant sources to procure exudates and other foods via active gouging. It is now apparent that slow lorises belong to this rare guild of obligate exudativorous primates. We investigate the diet of the pygmy loris (Nycticebus pygmaeus) in a mixed deciduous forest in the Seima Protection Forest, Eastern Cambodia, and attempted to determine the importance of this resource in their diet. Feeding behaviors of six females and seven males were observed using radio‐tracking to facilitate follows, and nine fecal samples were collected in February–May and January–March in 2008 and 2009 respectively. We observed 168 feeding bouts, during which the animals ate exudates (76); fruits (33); arthropods (27); flower parts (21); fungi (3); parts of bamboo culms (7); and reptiles (1). We filmed 19 bouts of exudativory, and observed animals consuming exudates in an orthograde posture, or standing quadrupedally over the exudate source. Pygmy lorises also gouged bamboo to collect lichen and fungi, or broke open dead culms to access invertebrates. Feeding occurred on terminal tree branches (24), tree trunks (21), bamboo (13), the middle of branches (7), and the undergrowth (1). The fecal samples contained plant parts, small‐sized arthropods (primarily Coleoptera and Lepidoptera), reptile scales, animal bones, and animal hairs. Pygmy slow lorises are morphologically specialized for processing and digesting exudates, displaying small body sizes, specialized dentitions, elongated, and narrow tongues, large caecums, short duodenums, expanded volar pads, and modified hindlimbs. These features, combined with the prevalence of exudates in their diet across seasons, and ill health when exudates are missing from their diet in captivity, points to this species being an obligate exudativore.

Published: June 2013

ABSTRACTIn this article, we report the degradation of poly(ethylene terephthalate) (PET), which occurs through glycolysis in the presence of dimethyl tin distanoxane [(CH3)2Sn(OCOCH3)2] as a catalyst, triethylene glycol (TEG) as a nucleophilic agent, and decaline like a solvent. A number of experiments were executed, which were derived from a factorial experimental design, in which the reaction time was between 40 and 60 min, the amount of TEG was between 3.4 and 5.6 g, and the amount of catalyst was between 0.04 and 0.06% in ratio to PET. The reaction temperature was constant at 175°C in all of the experiments. Once the glycolytic depolymerization occurred, oligomers with a molecular weight around 6000 g/mol were obtained. These oligomers were analyzed through gel permeation chromatography, differential scanning calorimetry, Fourier transform infrared spectroscopy, and 1H‐NMR. © 2013 Wiley Periodicals, Inc. J. Appl.
