Authors: Pegolo Lisandra Cristina Nogueira Cabril , Demattê Maria Esmeralda Soares Payão 
Published: January 2017

As praças e os jardins sempre povoaram o imaginário humano. Dentro das cidades, melhoram a qualidade de vida e embelezam a paisagem. Muito importantes no passado, esses espaços verdes têm história e memória próprias, que são pouco lembradas atualmente. O presente trabalho estudou as principais praças de duas cidades do interior
paulista – Jaboticabal e Taquaritinga – a fim de verificar que relações vêm ocorrendo entre os habitantes e essas praças no decorrer do tempo. Os resultados obtidos mostraram
que, de acordo com a época, maneiras diferentes existem em como as pessoas usufruem das praças de suas cidades. Verificaram-se também poucas semelhanças entre
jaboticabalenses e taquaritinguenses, no que diz respeito a como interagem com as suas praças.
CONDICIONANTES DO DESENVOLVIMENTO SUSTENTÁVEL DO LITORAL NORTE PAULISTA – O EXEMPLO DA BACIA DO CÓRREGO DA LAGOINHA – UBATUBA – SP, BRASIL.

Published: January 2017

O Litoral Norte do Estado de São Paulo tem uma vocação natural para atividades relacionadas ao turismo, especialmente sob o prisma da utilização dos recursos
naturais das praias e águas costeiras. As análises sistemáticas realizadas pela CETESB sobre a qualidade das águas costeiras evidenciam degradação, especialmente pela
contaminação com esgoto doméstico.
O trabalho realizado procura identificar as condicionantes para o desenvolvimento sustentável baseado no turismo para uma área representativa tomada como modelo. A área escolhida foi a Bacia Hidrográfica do Córrego da Lagoinha,
localizada no Município de Ubatuba. Esta escolha foi decorrente de suas características físicas e antrópicas típicas da região.
Foram organizadas cartas temáticas básicas e cartas integradas na escala de 1:10.000, caracterizadas a atual situação deste geossistema, a legislação municipal
estudos da correlação dessa área no contexto regional. Para interpretar os dados foram utilizados métodos de listagens, matrizes e análise espacial.
Foram identificados como fatores condicionantes, as formações geológicas, os recursos hídricos, a legislação, o sistema viário, a variação relativa do nível médio do
mar e a tendência atual do processo de urbanização. São feitas sugestões para mitigar os efeitos das ações antrópicas sobre a qualidade ambiental que comprometem o turismo
daquela região.
FABRICAÇÃO DE BLOCOS ESTRUTURAIS DE CONCRETO COM RESÍDUOS DE BORRACHA DE PNEUS
Authors: Fioriti César Fabiano , Akasaki Jorge Luis 
Published: January 2017

O presente trabalho avalia a técnica de fabricação de blocos de concreto com função estrutural utilizáveis em alvenaria. Foram adicionados nos compósitos de concreto, resíduos de borracha provenientes do processo mecânico de recauchutagem de pneus. Prepararam-se cinco diferentes dosagens de concreto contendo resíduos de borracha e uma sem resíduos para servir como referência. Aos 28 dias de idade os blocos produzidos foram submetidos aos ensaios de resistência mecânica à compressão simples e capacidade de absorção de água.
O intuito deste trabalho foi à obtenção de um possível material alternativo para a indústria da construção civil, contribuindo dessa maneira para a proteção ambiental e a conservação das fontes naturais de materiais convencionalmente utilizados, pois os resíduos da recauchutagem de pneus podem ser definidos como resíduos sólidos particularmente intratáveis, já que sua decomposição pode se estender até 240 anos. E embora existam oportunidades para reciclagem dos resíduos de pneus, o mercado brasileiro está longe de consegui-lo visto à enorme quantidade deste material que é acumulada.

Nematóides entomopatogênicos são usados no controle biológico de vários insetos/praga. Ocorrem naturalmente, e há grande interesse em conhecer as condições do ambiente que possam favorecer suas atividades no solo para localizar hospedeiros potenciais e sua sobrevivência. O objetivo deste trabalho foi determinar o efeito da torta de filtro (T.F.) adicionada ao solo (SO) sobre a migração e persistência de
Steinernema glaseri. Os tratamentos consistiram de 0, 25, 50, 75 e 100% de T.F. adicionados em solo esterilizado: arenoso e argiloso. Galleria mellonella (Lepidoptera:Pyralidae) foi usada como hospedeiro indicador para a atividade dos juvenis infectivos do nematóide. No solo arenoso, a adição de T.F. em proporção de até 50% não influenciou a migração de nematóides em direção ao hospedeiro, enquanto em solo argiloso a proporção máxima onde ocorreu a migração foi de 25% T.F. Os juvenis infectivos moveram-se mais para a superfície do que para o fundo da coluna quando o substrato continha solo arenoso. Em solo argiloso, a movimentação foi semelhante nas duas direções em todos os teores de T.F. A persistência do
nematóide foi mais elevada em substratos com solo argiloso, nos tratamentos com maior proporção de solo em relação à torta de filtro.

Authors: Silveira Paulo Edison Martins da , Nobrega Carlos Alberto 
Published: January 2017

A geração de resíduos de construção e demolição constitui um grande problema ambiental. Em Piracicaba, SP, são geradas aproximadamente 620 toneladas/dia deste resíduo. O problema acarreta diversos prejuízos ambientais, tais
como: disposição irregular dos resíduos agregando lixo e atraindo animais transmissores de doenças; entulhos em vias públicas e córregos afetando a drenagem e a estabilidade de encostas; degradação visual urbana; redução da vida útil de aterros e de recursos minerais não renováveis. Os municípios buscam atender às exigências da Resolução 307 (CONAMA, 2002) empreendendo ações para o reaproveitamento
desses resíduos como agregado para pavimentação, fechamento de valas e confecção de artefatos de concreto. Há, entretanto, necessidade de sua utilização em maior
escala, possibilitando que estes materiais passem a constituir alternativas economicamente viáveis. Assim, propõe-se sua utilização como agregado no compósito solo-cimento. Foram testadas propriedades físicas, tecnológicas e químicas de misturas contendo resíduo de construção civil reciclado e solo em diferentes proporções resíduo/solo. Verificou-se que as misturas nas proporções de 50%, 75% e 100% atendem às especificações tecnológicas para emprego como solocimento.
Quanto aos aspectos químicos, a utilização do resíduo como agregado no solo-cimento se mostrou exeqüível e eficiente no encapsulamento de contaminantes.

Authors: Kausar A. 
Published: January 2017

Abstract
In this effort, blend membrane of polycarbonate (PC) and polypropylene-graft-maleic anhydride (PPMA) was fabricated via phase inversion technique. The nano-zeolite (NZ) was employed as nanofiller. Morphology of PC/PPMA/NZ membrane revealed unique inter-connected branched microstructure. Tensile strength and Young’s Modulus of PC/PPMA/NZ 0.1-5 were in the range of 59.9-74.5 MPa and 111.4-155.2 MPa respectively. The nano-zeolite filler was also effective in enhancing the permselectivity αCO2/N2 (23.5 to 38.5) relative to blend membrane (20.3). The permeability PCO2 of PC/PPMA/NZ 5 membrane was found as 106.2 Barrer. Filler loading enhanced gas diffusivity, however filler content did not significantly influence CO2 and N2 solubility.

Published: January 2017

Abstract
Dual-channel evaluation of surface electromyogram (SEMG) signals acquired from amputee subjects using computational techniques for classification of arm motions is presented in this study. SEMG signals were classified by the neural network (NN) and interpretation was done using statistical techniques to extract the effectiveness of the recorded signals. From the results, it was observed that there exists a calculative difference in amplitude gain across different motions and that SEMG signals have great potential to classify arm motions. The outcomes indicated that the NN algorithm performs significantly better than other algorithms, with a classification rate (CR) of 96.40%. Analysis of variance (ANOVA) presents the results to validate the effectiveness of the recorded data to discriminate SEMG signals. The results are of significant thrust in identifying the operations that can be implemented for classifying upper-limb movements suitable for prostheses’ design.
Convolutive blind source separation of surface EMG measurements of the respiratory muscles
Authors: Petersen Eike , Buchner Herbert , Eger Marcus , Rostalski Philipp 
Published: January 2017

AbstractElectromyography (EMG) has long been used for the assessment of muscle function and activity and has recently been applied to the control of medical ventilation. For this application, the EMG signal is usually recorded invasively by means of electrodes on a nasogastric tube which is placed inside the esophagus in order to minimize noise and crosstalk from other muscles. Replacing these invasive measurements with an EMG signal obtained non-invasively on the body surface is difficult and requires techniques for signal separation in order to reconstruct the contributions of the individual respiratory muscles. In the case of muscles with small cross-sectional areas, or with muscles at large distances from the recording site, solutions to this problem have been proposed previously. The respiratory muscles, however, are large and distributed widely over the upper body volume. In this article, we describe an algorithm for convolutive blind source separation (BSS) that performs well even for large, distributed muscles such as the respiratory muscles, while using only a small number of electrodes. The algorithm is derived as a special case of the TRINICON general framework for BSS. To provide evidence that it shows potential for separating inspiratory, expiratory, and cardiac activities in practical applications, a joint numerical simulation of EMG and ECG activities was performed, and separation success was evaluated in a variety of noise settings. The results are promising.

Abstract
Linear dynamic analysis of cardiovascular and respiratory time series was performed in healthy subjects with respect to gender by shifted short-term segments throughout a head-up tilt (HUT) test. Beat-to-beat intervals (BBI), systolic (SYS) and diastolic (DIA) blood pressure and respiratory interval (RESP) time series were acquired in 14 men and 15 women. In time domain (TD), the descending slope of the auto-correlation function (ACF) (BBI_a31cor) was more pronounced in women than in men (p<0.05) during the HUT test and considerably steeper (p<0.01) at the end of orthostatic phase (OP). The index SYS_meanNN was slightly but significantly lower (p<0.05) in women during the complete test, while higher respiratory frequency and variability (RESP_sdNN) were found in women (p<0.05), during 10–20 min after tilt-up. In frequency domain (FD), during baseline (BL), BBI-normalized low frequency (BBI_LFN) and BBI_LF/HF were slightly but significantly lower (p<0.05), while normalized high frequency (BBI_HFN) was significantly higher in women. These differences were highly significant from the first 5 min after tilt-up (p<0.01) and highly significant (p<0.001) during 10–14 min of OP. Findings revealed that men showed instantaneously a pronounced and sustained increase in sympathetic activity to compensate orthostatism. In women, sympathetic activity was just increased slightly with delayed onset without considerably affecting sympatho-vagal balance.

Published: January 2017

AbstractBackground:Meta-analyses indicated the breakdown of copper homeostasis in the sporadic form of Alzheimer’s disease (AD), comprising copper decreases within the brain and copper increases in the blood and the pool not bound to ceruloplasmin (non-Cp Cu, also known in the literature as “free” copper). The calculated non-Cp Cu (Walshe’s) index has many limitations.Methods:A direct fluorescent method for non-Cp Cu detection has been developed and data are presented herein. The study included samples from 147 healthy subjects, 36 stable mild cognitive impairment (MCI) and 89 AD patients, who were tested for non-Cp Cu through the direct method, total serum copper, ceruloplasmin concentration andResults:The direct method was linear (0.9–5.9 μM), precise (within-laboratory coefficient variation of 9.7% for low and 7.1% for high measurements), and had a good recovery. A reference interval (0–1.9 μM) was determined parametrically in 147 healthy controls (27–84 years old). The variation of non-Cp Cu was evaluated according to age and sex. Non-Cp Cu was 1.5 times higher in AD patients (regarding the upper value of the reference interval) than in healthy controls. Healthy, MCI and AD subjects were differentiated through the direct non-Cp Cu method [areas under the curve (AUC)=0.755]. Considering a 95% specificity and a 1.91 μmol/L cut-off, the sensitivity was 48.3% (confidence interval 95%: 38%–58%). The likelihood ratio (LR) was 9.94 for positive test results (LR+) and 0.54 for negative test result (LR−).Conclusions:The direct fluorescent test reliably and accurately measures non-Cp Cu, thereby determining the probability of having AD.
The Possibility of Hybrid-Bioreactor Heating by the Microwave Radiation
Authors: Zieliński Marcin , Dębowski Marcin 
Published: January 2017

Abstract
The hybrid bioreactor heated by microwave or conventional by hot water jacket is presented. The reactor consisted of two functional sections. The upper section was constituted by an unsinkable anaerobic biological bed, whereas the bottom section – by suspended anaerobic activated sludge. Both sections were closed in one casing. The study was conducted in mesophilic (35 °C) and thermophilic (55 °C) conditions. Depending on the method of heating, the homogeneity of the temperature field in both functional parts of the reactor was determined. In mesophilic conditions only at measurement points located directly under the wave-guide the temperatures were significantly higher than in the other zones inside the reactor. This implies that it is possible to homogenous heat of the bioreactor in semi-technical scale by microwave irradiation. Under thermophilic conditions a homogenous field of temperature was obtained in the upper and in the bottom section of the bioreactor, however, significant differences were found in values of the temperature between the particular sections of the bioreactor.
Granular Flow of Corn Stover Particles in a Helical Ribbon Stirred Tank
Authors: Huang Juan , Dai Gance 
Published: January 2017

Abstract
The flow characteristics and power consumption of corn stover particles in a helical ribbon stirred tank was investigated in the context of simultaneous saccharification and fermentation of corn stover at high solids loading. It was found that the particles in the tank can be divided into conveyed material and core material according to their flow characteristics. The flow of the former materials was frictional regime and the latter was intermediate flow; the conveyed material avalanched into the core at the top of granular bed. The granular bed dilated when the impeller was rotating, which was beneficial for the entrance of liquid enzyme into the solid phase and for the successful proceeding of the saccharification of the corn stover. The power of granular mixing was linearly proportional to the impeller rotational speed due to the discrete characteristic of the particles and flow dynamics of the conveyed material. The ratio of power consumption to the impeller rotational speed (P/N) was linear proportional to loading ratio and the dimensionless torque (M/mgR) was 0.48. The power consumption increased first and then decreased as the corn stover particles evolved from granular/wet granular to paste/slurry. The maximum power consumption was at 83 % (w/w) moisture content.

Published: January 2017

Abstract
A 500 L biomass fast pyrolysis Auger reactor was designed, constructed and experimented with biomass of Mesquite (Prosopsis juliflora) and rice straw (Oryza sativa). The thermogravimetric analysis of feed stock and the physico chemical properties of the feed and product bio-crude was done as per ASTM standard. An optimization based on Response Surface Methodology was carried out for the operating parameters chosen as: (1) reactor temperature, (2) feedstock-heat carrier ratio and (3) rotational speed of the auger reactor. The optimum bio-crude yield of 42.6 wt.% was observed at 500 °C, feedstock-heat carrier ratio 1:2 and 30 rpm for mesquite sawdust and 34.6 wt.% at 475 °C, 1:2 ratio and 50 rpm for rice straw. Among the two kinds of feedstock tested, the sawdust yielded better product under identical operating conditions. The final bio-crude have properties similar to the results that was reported in the past and has HHV- higher heating value less than petroleum fuel.
Upgrading of Heavy Oil in Supercritical Water using an Iron based Multicomponent Catalyst
Authors: Hossain Mohammad M. 
Published: January 2017

Abstract
This article deals with the upgrading of bitumen in supercritical water (SCW) using a ZrO2-Al2O3-FeOx catalyst in a batch autoclave reactor. The feed bitumen is diluted using different amount of benzene as solvent in order to provide intimate contact between the solid catalyst particles. It also facilitates the diffusion of the heavy molecules into the catalyst particles. The batch reactor results show that the extra heavy oil is slightly decreased with increasing the bitumen concentration from 20 wt % to 30 wt%. No significant change in the product is observed when bitumen concentration is increased above 30 wt% level. However, the coke concentration is increased with increasing bitumen in the feed. The catalyst deactivation is also higher at higher bitumen concentrations (above 20 wt %). XRD analysis reveals that at high bitumen concentrations (above 30 wt %), transformation of magnetite into hematite is lower than that of hematite to magnetite due to consumption of lattice oxygen by the additional hydrocarbons, which also causes the catalyst deactivation. On the contrary, lower bitumen concentration (~10 wt %) maintains hematite as main phase, which is the desirable for sustained catalytic activity for the oxidative cracking reaction. It is believed that SCW acts as source of reactive hydrogen and oxygen species that favors the upgrading process. The reactive hydrogen species react with cracked hydrocarbons to produce stable lighter liquid products. On the other hand, the reactive oxygen species react with oxygen depleted catalysts, which transforms magnetite into hematite and keep the catalyst active.
