13. Can a lexical decision task predict efficiency in the judgment of ambiguous sentences?
Abstract The lexicon plays a fundamental role in reading, but little is known about how it influences reading efficiency. Thus, this study seeks to identify which lexical factors in a lexical decision task are relevant in a semantic decision test. A total of 33 university students were recruited to perform a lexical decision task and a semantic decision task

14. Structural reliability analysis of steel plane frames with semi-rigid connections
Abstract The design codes for structural design traditionally establish the adoption of partial safety factors to deal with uncertainties. These standards do not allow one to know the real probabilities of failure of a structure. What is needed, from a practical and scientific point of view, is a more consistent approach, based on reliability theory. This ar

15. Integración de captación activa y pasiva en viviendas unifamiliares de emprendimientos inmobiliarios
Abstract This study analyses the possibility of achieving negative energy demands in single-family housing (Plus-Energy House). Through the integration of energy efficiency measures jointly with active solar systems, it is possible to obtain high performance energy models. In order to demonstrate this, we performed energy simulations integrating active solar

16. A Quantitative Comparison Between Size, Shape, Topology and Simultaneous Optimization for Truss Structures
Abstract There are typically three broad categories of structural optimization namely size, shape and topology. Over the past few decades various researchers have focused on developing techniques for optimizing structures by considering either one or a combination of these aspects. In this paper the efficiency of these techniques are investigated in an effor

17. ANAEROBIC DIGESTION STABILITY TEST BY SHEWHART CONTROL CHART
ABSTRACT The anaerobic digestion (AD) operation complexity raise the importance of stability testing to verify whether the operating conditions are under control and whether the process is working as required. The current method of verifying process stability is by a range of the ratio between volatile fatty acidity and total alkalinity (VFA/ TA) within whic

18. ASSESSMENT OF CO2 EMISSION MITIGATION FOR A BRAZILIAN OIL REFINERY
Abstract Currently the oil refining sector is responsible for approximately 5% of the total Brazilian energy related CO2 emissions. Possibilities to reduce CO2 emissions and related costs at the largest Brazilian refinery have been estimated. The abatement costs related to energy saving options are negative, meaning that feasibility exists without specific i

19. Efficiency of Electrical Stunning by Electronarcosis: Current Situation and Perspective of Improvement in a Medium-Size Processing Plant
ABSTRACT The objective of this study was to evaluate the efficiency of electrical stunning by electronarcosis in a medium-size poultry processing plant located in southern Brazil. The current measurement of this type of stunning is presented, and then improvements to this method are proposed. Data were collected for 90 days. A quality indicator was proposed:

20. Phonological awareness intervention and attention efficiency in children at risk: evidence of effectiveness on visual attention
ABSTRACT Using a pretest and posttest comparison group design, this 20 weeks study investigated the effects of a phonological awareness training program (PATP) on attention efficiency (AE) in 57 children (age = 5 to 6 years) at risk. The experimental group received the PATP (EG; n=30). We obtained pretest and posttest measures of phonological awareness and A

21. The effectiveness of the head-turn-plus-chin-down maneuver for eliminating vallecular residue
ABSTRACT Purpose When swallowing efficiency is impaired, residue accumulates in the pharynx. Cued or spontaneous swallows in the head neutral position do not always successfully clear residue. We investigated the impact of a novel maneuver on residue clearance by combining a head turn with the chin down posture. Methods Data were collected from 26 particip

22. Assessing carriers’ logistical performance indicator by shippers in the São Paulo Metropolitan Area
Abstract This paper aims to assess the logistics services provided by carriers in the São Paulo Metropolitan Area (SPMA) considering two perspectives: the efficiency of the operations and the adoption of sustainable measures. A survey was applied to the 15 main shippers working with the selected carrier in order to assess logistics performance indicators (o

23. The Caughey absorbing layer method - implementation and validation in Ansys software
AbstractThis paper addresses the Caughey Absorbing Layer Method (CALM) performance in the one-dimensional problem and its implementation in commercial software, with possibility of direct extension to two-dimensions. The adequacy and numerical efficiency is evaluated using three different error measures and five different variations of the damping profile. O

24. Optimisation of a quantitative polymerase chain reaction-based strategy for the detection and quantification of human herpesvirus 6 DNA in patients undergoing allogeneic haematopoietic stem cell transplantation
Human herpesvirus 6 (HHV-6) may cause severe complications after haematopoietic stem cell transplantation (HSCT). Monitoring this virus and providing precise, rapid and early diagnosis of related clinical diseases, constitute essential measures to improve outcomes. A prospective survey on the incidence and clinical features of HHV-6 infections after HSCT has
