Children's Lie-Telling and Self-Awareness as an Honesty Promoting Technique

The present study investigated how social-cognitive development relates to children’s lie-telling and the effectiveness of a novel honesty promoting technique (i.e., self-awareness). Sixty-four children were asked not to peek at a toy in the experimenter’s absence and were later asked about whether they had peeked as a measure of their honesty. Half of the children were questioned in the self-awareness condition and half in the control condition. Additionally, children completed a battery of cognitive and social-cognitive tests to assess executive functioning and theory-of-mind understanding. While first-order theory-of-mind understanding, inhibitory control, and visuospatial working memory did not significantly relate to children’s lie-telling, measures of inhibitory control in conjunction with working memory and complex working memory were significantly related to children’s lie-telling. Finally, the novel honesty promoting technique was effective: children in the self-aware condition lied significantly less often than children in the control condition.

Análise da sensibilidade do biodiesel B5 em frotas de transporte coletivo com motorização diesel

The aim of this study was investigate the consolidation of the biodiesel fuel used in (a) engines of urban and intercity bus companies, (b) a stationary engine. It was necessary to investigate and analyze, technologically, if the biodiesel fuels were presenting troubleshooting relative to wear of parts lied to fuel and to evaluate the consumption fluctuations of this fuel. The urban and intercity bus companies, localized in Natal, Rio Grande do Norte state, Brazil, had 41 and 12 vehicles, respectively. It were analyzed datasheet of each one vehicle during three years, since 2008 until 2010 and were interviewed the management of the maintenance team of bus companies relative to aspects concerning the substitution of the diesel fuel by the B5 biodiesel. The second aim of this study was visually inspect the wear of the parts directly lied to combustion process. For this reason, it was investigated a stationary engine, manufactured by Branco BD5, 5 HP of power, fueled by (a) diesel, (b) biodiesel B5, (c) biodiesel B20 and (d) diesel or biodiesel, both contaminated by distilled water. In this engine, its power utilizing biodiesel B5 versus diesel was lower about 5.2% and, in the investigated case of B20 versus diesel, it was lower around 11.5%

Floristic composition of the tree stratum of a semideciduous mesophytic forest in the municipality of Jahu, SP, Brazil

A floristic study was carried out in an area of semideciduous mesophytic forest, lied in the municipality of Jahu, São Paulo State, Brazil. Due to the fact of the forest be crossed by three small rivers, for the sampling process, the forest was divided in two sampling areas: Area I (under the influence of the rivers) and Area II (without this influence). Differences in the abundance of some species between the two sampling areas were observed.

Floristic composition of the tree stratum of a semideciduous mesophytic forest in the municipality of Botucatu, São Paulo state

The floristic composition was studied in an area of semideciduous mesophytic forest, with 120 ha, in the municipality of Botucatu, SP, Brazil. This forest lies on the ascent of the Cuesta of Botucatu. Due to the heterogeneity of the relief, for the sampling process, the forest was divided in three regions: the upper one (comprising the strip of forest on the plateau), middle on (the forestal area lied on the ascent properly said) and the lower one (the strip of forest on the plain). The tree sampling regions showed some differences among them and this must be connected to the differences in the soil.

Phytosociological study of the tree stratum of a semideciduous mesophytic forest in the municipality of Botucatu, SP, Brazil

The phytosociological structure was studied in an area of semideciduous mesophytic forest lied on the ascent of the Cuesta of Botucatu. Once the relief of the area was very heterogeneous, the forest, for the sampling process, was divided in three sampling regions: the upper one (on the plateau), the middle one (on the ascent properly said) and the lower one (on the plain). Through the point-centered method, 1224 (408 in each region) trees were sampled. For this work, only the trees with shaft equal or higher than 1.30m high were considered. The three sampling regions showed some interesting differences in regard to the phytosociologic structure. Once there are differences among the soil of the three regions, the variations in the structure must be connected to the differences in the soil.

Rheology and fluid dynamics properties of sugarcane juice

The sugarcane juice is a relatively low-cost agricultural resource, abundant in South Asia, Central America and Brazil, with vast applications in producing ethanol biofuel. In that way, a good knowledge of the rheological properties of this raw material is of crucial importance when designing and optimizing unit operations involved in its processing. In this work, the rheological behavior of untreated (USCJ, 17.9 °Brix), clarified (CSCJ, 18.2 °Brix) and mixed (MSCJ, 18.0 °Brix) sugarcane juices was studied at the temperature range from 277K to 373K, using a cone-and-plate viscometer. These fluids were found to present a Newtonian behavior and their flow curves were well-fitted by the viscosity Newtonian model. Viscosity values lied within the range 5.0×10 -3Pas to 0.04×10 -3Pas in the considered temperature interval. The dependence of the viscosity on the temperature was also successfully modeled through an Arrhenius-type equation. In addition to the dynamic viscosity, experimental values of pressure loss in tube flow were used to calculate friction factors. The good agreement between predicted and measured values confirmed the reliability of the proposed equations for describing the flow behavior of the clarified and untreated sugarcane juices. © 2010 Elsevier B.V.

Broadband NIR emission in novel sol-gel Er3+-doped SiO 2-Nb2O5 glass ceramic planar waveguides for photonic applications

This paper reports on the sol-gel preparation and structural and optical characterization of new Er3+-doped SiO2-Nb 2O5 nanocomposite planar waveguides. Erbium-doped (100-x)SiO2-xNb2O5 waveguides were deposited on silica-on-silicon substrates and Si(1 0 0) by the dip-coating technique. The waveguides exhibited uniform refractive index distribution across the thickness, efficient light injection at 1538 nm, and low losses at 632 and 1538 nm. The band-gap values lied between 4.12 eV and 3.55 eV for W1-W5, respectively, showing an excellent transparency in the visible and near infrared region for the waveguides. Fourier Transform Infrared (FTIR) Spectroscopy analysis evidenced SiO2-Nb2O5 nanocomposite formation with controlled phase separation in the films. The HRTEM and XRD analyses revealed Nb2O5 orthorhombic T-phase nanocrystals dispersed in a silica-based host. Photoluminescence (PL) analysis showed a broad band emission at 1531 nm, assigned to the 4I13/2 → 4I15/2 transition of the Er3+ ions present in the nanocomposite, with a full-width at half medium of 48-68 nm, depending on the niobium content and annealing. Hence, these waveguides are excellent candidates for application in integrated optics, especially in EDWA and WDM devices. © 2012 Elsevier B.V. All rights reserved.

Kasabach-Merritt syndrome: clinical vs. surgical treatment

Kassabach-Merritt syndrome is a combination of capillary hemangioma and thrombocytopenia that predisposes to bleeding with petechiae, ecchymosis and spontaneous bruising. Treatment is generally started with corticosteroids, interferon alpha or chemotherapy. We present the case of a child (aged 1 year and 9 months) with a giant hemangioma, from the root of the thigh to the knee, and thrombocytopenia. Treatment was started with corticosteroids, without improvement, and then intra-tumor and cutaneous bleeding appeared spontaneously. The patient’s clinical condition precluded prescription of vincristine and interferon and emergency tumor resection was conducted because of extreme thrombocytopenia and bleeding. The child then began to develop sepsis with hypotension and ischemia of remnant tissues. This case presented a therapeutic challenge, which is the subject of this article.

Funktionelle Analyse der Gliazellwanderung im Drosophila-Embryo

Gliazellen kommen in allen höheren Organismen vor und sind sowohl für die korrekte Entwicklung, als auch für die Funktionalität des adulten Nervensystems unerlässlich. Eine der mannigfachen Funktionen dieses Zelltyps ist die Umhüllung von Axonen im zentralen und peripheren Nervensystem (ZNS und PNS). Um eine vollständige Umhüllung zu gewährleisten, wandern Gliazellen während der Neurogenese zum Teil über enorme Distanzen von ihrem Entstehungsort aus. Dies trifft insbesondere auf die Gliazellen zu, durch deren Membranausläufer die distalen Axonbereiche der peripheren Nerven isoliert werden.rnIn dieser Arbeit wurde die Migration von Gliazellen anhand des Modelorganismus Drosophila untersucht. Ein besonderes Interesse galt dabei der Wanderung einer distinkten Population von Gliazellen, den sogenannten embryonalen Peripheren Gliazellen (ePG). Die ePGs werden überwiegend im sich entwickelnden ventralen Bauchmark geboren und wandern anschließend entlang der peripheren Nerventrakte nach dorsal aus, um diese bis zum Ende der Embryogenese zu umhüllen und dadurch die gliale Blut-Nerv-Schranke zu etablieren. Das Hauptziel dieser Arbeit bestand darin, neue Faktoren bzw. Mechanismen aufzudecken, durch welche die Migration der ePGs reguliert wird. Dazu wurde zunächst der wildtypische Verlauf ihrer Wanderung detailliert analysiert. Es stellte sich heraus, dass in jedem abdominalen Hemisegment eine invariante Anzahl von 12 ePGs von distinkten neuralen Vorläuferzellen generiert wird, die individuelle Identitäten besitzen und mittels molekularer Marker auf Einzelzellebene identifiziert werden können. Basierend auf der charakteristischen Lage der Zellen erfolgte die Etablierung einer neuen, konsistenten Nomenklatur für sämtliche ePGs. Darüber hinaus offenbarten in vivo Migrationsanalysen, dass die Wanderung individueller ePGs stereotyp verläuft und demzufolge weitestgehend prädeterminiert ist. Die genaue Kenntnis der wildtypischen ePG Migration auf Einzelzellebene diente anschließend als Grundlage für detaillierte Mutantenanalysen. Anhand derer konnte für den ebenfalls als molekularen Marker verwendeten Transkriptionsfaktor Castor eine Funktion als zellspezifische Determinante für die korrekte Spezifizierung der ePG6 und ePG8 nachgewiesen werden, dessen Verlust in einem signifikanten Migrationsdefekt dieser beiden ePGs resultiert. Des Weiteren konnte mit Netrin (NetB) der erste diffusible und richtungsweisende Faktor für die Migration von ePGs enthüllt werden, der in Interaktion mit dem Rezeptor Uncoordinated5 speziell die Wanderung der ePG6 und ePG8 leitet. Die von den übrigen Gliazellen unabhängige Navigation der ePG6 und ePG8 belegt, dass zumindest die Migration von Gruppen der ePGs durch unterschiedliche Mechanismen kontrolliert wird, was durch die Resultate der durchgeführten Ablationsexperimente bestätigt wird. rnFerner konnte gezeigt werden, dass während der frühen Gliogenese eine zuvor unbekannte, von Neuroblasten bereitgestellte Netrinquelle an der initialen Wegfindung der Longitudinalen Gliazellen (eine Population Neuropil-assoziierter Gliazellen im ZNS) beteiligt ist. In diesem Kontext erfolgt die Signaldetektion bereits in deren Vorläuferzelle, dem Longitudinalen Glioblasten, zellautonom über den Rezeptor Frazzled. rnFür künftige Mutantenscreens zur Identifizierung weiterer an der Migration der ePGs beteiligter Faktoren stellt die in dieser Arbeit präsentierte detaillierte Beschreibung eine wichtige Grundlage dar. Speziell in Kombination mit den vorgestellten molekularen Markern liefert sie die Voraussetzung dafür, individuelle ePGs auch im mutanten Hintergrund zu erfassen, wodurch selbst subtile Phänotypen überhaupt erst detektiert und auf Einzelzellebene analysiert werden können. Aufgrund der aufgezeigten voneinander unabhängigen Wegfindung, erscheinen Mutantenanalysen ohne derartige Möglichkeiten wenig erfolgversprechend, da Mutationen vermutlich mehrheitlich die Migration einzelner oder weniger ePGs beeinträchtigen. Letzten Endes wird somit die Aussicht verbessert, weitere neuartige Migrationsfaktoren im Modellorganismus Drosophila zu entschlüsseln, die gegebenenfalls bis hin zu höheren Organismen konserviert sind und folglich zum Verständnis der Gliazellwanderung in Vertebraten beitragen.
