Avaliação in vitro do efeito da desproteinização da dentina decídua de humanos na união de sistemas adesivos
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Odontologia, Florianópolis, 2009.O objetivo deste estudo, in vitro, foi avaliar a resistência de união à microtração e a nanoinfiltração, após desproteinização da dentina decídua humana. Foram utilizadas coroas de molares decíduos hígidos, as quais tiveram a superfície oclusal desgastada com lixas de carbeto de silício, até a completa exposição da superfície dentinária, e para padronização da smear layer. Os espécimes foram distribuídos em seis grupos, de acordo com o tipo de tratamento (condicionamento ácido - CA ou CA + hipoclorito de sódio - NaOCl) e os sistemas adesivos: One Step Plus - Bisco (OSP), Single Bond - 3M ESPE (SB), Prime & Bond 2.1 - Dentsply (PB). Para o procedimento de desproteinização foi utilizado hipoclorito de sódio 10% por 30s. Os sistemas adesivos e a resina (Filtek Z 250 - 3M ESPE) foram aplicados de acordo com as recomendações dos fabricantes e os espécimes armazenados em água destilada (37ºC/24h). As coroas foram seccionadas obtendo-se palitos (0,8mm2), os quais foram imediatamente submetidos ao teste de resistência à microtração (Instron - 0,5mm/min), até fratura dos corpos-de-prova. Os valores obtidos foram analisados por ANOVA e teste de Tukey (p<0,05). Os corpos-de-prova foram levados ao microscópio eletrônico de varredura (MEV), para visualização do tipo de fratura e os dados submetidos ao teste de Kruskal-Wallis (p<0,05).A nanoinfiltração foi avaliada utilizando-se palitos e nitrato de prata amoniacal como marcador químico. A deposição da prata foi visualizada ao MEV e analisada de duas formas: 1. Em porcentagem (%), em três regiões do palito, utilizando-se espectometria por energia dispersa por raio-x (EDS); 2. Atribuição de escores pela avaliação das fotomicrografias obtidas ao MEV. Os dados (%) foram analisados por ANOVA e teste de Tukey (p<0,05) e os escores submetidos aos testes de Kruskal-Wallis e U de Mann-Whitney (p<0,05).Os valores médios obtidos para o teste de microtração sem desproteinização foram [MPa(DP)]: PB - 35,95(6,12); SB - 28,82(6,38); OSP - 24,59(6,10); e após desproteinização: PB - 41,47(6,79); OSP - 31,09(9,16); SB - 25,55(7,23). Os padrões de fratura mais comumente encontrados foram coesiva do adesivo e mista, para todos os grupos. A nanoinfiltração, avaliada por porcentagem, apresentou diferença significante para as variáveis tratamento e adesivo. A desproteinização da dentina condicionada reduziu significativamente a infiltração para o adesivo OSP. Para a variável sistema adesivo, na análise por porcentagem e por escores, o adesivo SB apresentou significativamente maior infiltração pelo nitrato de prata quando comparado ao OSP e PB, que foram similares entre si. Conclui-se que a resistência adesiva não foi influenciada pela remoção do colágeno exposto pelo condicionamento ácido e que a nanoinfiltração não foi evitada pela desproteinização dentinária
Hybrid protocol for wireless EH network over weibull fading channel: performance analysis
No full textIn this paper, the hybrid TSR-PSR protocol for wireless energy harvesting (EH) relaying network over the Weibull fading channel is investigated. The system network is working in half-duplex (HD) mode. For evaluating the system performance, the closed-form and integral-form expressions of the outage probability (OP) are investigated and derived. After that, numerical results convinced that our derived analytical results are the same with the simulation results by using Monte Carlo simulation. This paper provides a novel recommendation for the wireless EH relaying network

Building Core Competencies in a Turbulent Environment: An Exploratory Study of Firm Resources and Capabilities in Chinese Transitional Economy
No full textThe impact of firm resources and capabilities on performance among Chinese enterprises has been a subject of anecdotal speculation due to its significant implications for organizational researchers as well as practitioners. Yet empirical evidence has been very limited. In this research, set in the People’s Republic of China, we examine firm resources and capabilities and their impact on firm performance among Chinese enterprises. Using large sample of 12,047 Chinese firms from 1991 to 1992, we found that most of the firm specific resources and capabilities examined in this study have a positive impact on performance. We discussed the implications for organizational researchers, policy makers, and managers, and proposed directions for future research.economic transition, firm strategy, resources and capabilities
On the design of an energy-harvesting noise-sensing WSN mote
No full textWireless sensor networks (WSNs) could potentially help in the measurement and monitoring of noise levels, an important step in mitigating and fighting noise pollution. Unfortunately, the high energy required by the noise measurement process and the reliance of sensor motes on batteries make the management of noise-sensing WSNs cumbersome. Giving motes energy harvesting (EH) capabilities could alleviate such a problem, and several EH-WSNs have already been demonstrated. Nevertheless, the high-frequency nature of the data required to measure noise places significant additional challenges to the design of EH-WSNs. In this paper, we present a design and prototype for a mote extension which enables the mote to detect noise levels while being powered by energy harvesting. The noise level detection carried out by the system relies primarily on the concept of peak detection. Results of performance testing are presented. Aside from the hardware design and prototype, we also discuss methods of assigning charge times for application scenarios where there are multiple pulse loads. We also propose a new opportunistic method for charge time determination. Experiments demonstrate that the new method could improve analytically-derived duty cycles by at least 350%
Coverage Probability of EH-enabled LoRa networks - A Deep Learning Approach
No full textThe performance of energy harvesting (EH)-enabled long-range (LoRa) networks is analyzed in this work. Specifically, we employ deep learning (DL) to estimate the coverage probability (Pcov) of the considered networks. Our study incorporates a general fading distribution, specifically the Nakagami-m distribution, and utilizes tools from stochastic geometry (SG) to model the spatial distributions of all nodes and end-devices (EDs) with EH capability. The DL approach is employed to overcome the limitations of model-based methods that can only evaluate the Pcov under simplified network conditions. Therefore, we propose a deep neural network (DNN) that estimates the Pcov with high accuracy compared to the ground truth values. Additionally, we demonstrate that DL significantly outperforms the Monte Carlo simulation approach in terms of resource consumption, including time and memory
“Vi que era mujer y tan sujeta a pasiones y flaquezas como yo”: el intercambio epistolar entre Teresa de Jesús y Luisa de la Cerda
No full text“Vi que era mujer y tan sujeta a pasiones y flaquezas como yo”: The correspondence between Teresa of Ávila and Luisa de la Cerda The seven letters, that, as far as we know, Teresa of Ávila sent to Luisa de la Cerda, immerse us in the frenetic pace of life of the Carmelite Mother around the year 1568, when, thanks to the help of the Toledan noblewoman, she founded her second convent in Malagón Ciudad Real. Teresa’s anxiety over her autobiography arriving to Juan of Ávila is one of the main subjects of the letters: through this we can capture the mental state in which Teresa of Jesus lived, tormented by doubts about her spiritual raptures. Besides, as the letters are addressed to a feminine speaker, we can observe how Teresa of Ávila distanced herself from the coldness and formality of the theological and masculine universe and developed a new “feminine poetic,” that will later on dominate her main spiritual works.“Vi que era mujer y tan sujeta a pasiones y flaquezas como yo”: The correspondence between Teresa of Ávila and Luisa de la Cerda The seven letters, that, as far as we know, Teresa of Ávila sent to Luisa de la Cerda, immerse us in the frenetic pace of life of the Carmelite Mother around the year 1568, when, thanks to the help of the Toledan noblewoman, she founded her second convent in Malagón Ciudad Real.

Mechanical properties and fracture analysis of additively manufactured EH 36 steel parts by laser engineered net shaping process
No full textMetal additive manufacturing (AM) technologies have attracted a lot of interests from
many industrial sectors due to its unlimited capability of producing complex geometries. Metal parts
with complex shapes at large scales are highly demanded in marine and offshore (M&O) industries.
The aim of this paper is to ascertain the feasibility of Additive Manufacturing (to be more specific
Laser Engineered Net Shaping) of ASTM A131 EH 36 steel. After doing mechanical testing for LENS
processed ASTM A131 EH 36 samples, the LENS processed samples with horizontal build direction
have much better mechanical properties comparing with conventionally made parts, however samples with vertical build direction or 45 degree vertical build directions have properties comparable or lower than parts made of conventional methods due to build defects.NRF (Natl Research Foundation, S’pore)Published versio
