RESUMO Objetivo: Avaliar a habilidade de ordenação temporal com diferentes testes, verificar a especificidade desses testes e comparar o resultado com o grau de facilidade/dificuldade relatado pelos sujeitos. Métodos: Os indivíduos realizaram avaliação audiológica básica e Teste Dicótico de Dígitos, para triagem do processamento auditivo, e foram submetidos ao Teste Padrão de Frequência (TPF) e ao Teste Padrão de Duração (TPD), nas versões de Taborga-Lizarro, Musiek e Auditec®, para avaliar a habilidade de Ordenação Temporal. Após, foi apresentada a Escala Visual Analógica (EVA), para que os sujeitos identificassem a dificuldade de cada teste. Resultados: Foram avaliados 33 sujeitos, 29 do gênero feminino e quatro do gênero masculino, com idade entre 17 e 27 anos. Houve maior número de indivíduos que atingiram valores normais no teste Auditec® e de Taborga-Lizarro, para o TPD e TPF. No teste de Musiek, houve um número de sujeitos com resultados normais muito próximos aos de sujeitos com alteração de processamento. Na distribuição do teste mais difícil, houve significância estatística para o teste de Musiek. Quanto à especificidade dos testes, o Auditec® mostrou-se melhor, porém, a análise foi realizada apenas em TPF. Conclusão: Embora os indivíduos não tenham apresentado alteração e queixa de processamento auditivo, houve diferença nos resultados dos testes de ordenação temporal. Quanto ao grau de dificuldade relatado para o teste de Musiek, verificou-se que houve influência deste fator nos resultados dos testes. Na análise de especificidade dos testes, pôde-se observar melhores resultados para o teste Auditec®.

Abstract:

Application of TP as Tipimon® or TPA as Maxim® at the young fruitlet stage significantly increased yield in three lychee (Litchi chinensis Sonn.) cultivars: `Mauritius', `Floridian', and `Kaimana'. Application of TP followed by TPA a week later increased yield more than did either substance alone. In all experiments, TPA increased fruit size and weight, relative to both controls and TP-treated trees. The increased yield did not prevent the increase in fruit size. Use of sprays of TPA may be an effective way of satisfying the market demand for large lychee fruit. Chemical names used: 2,4,5-trichlorophenoxypropionic acid (TP); 3,5,6-trichloro-2-pyridyloxyacetic acid (TPA).

Abstract:

Quality seedlings production is one of the most important steps in the cultivation of vegetable species. In this sense, the objective was to evaluate the influence of different environments and substrates on the production of “pimenta-de-cheiro” (Capsicum chinense Jacq.) seedlings in Boa Vista, Roraima. An experiment was installed in a completely randomized design (CRD), with treatmentsarranged in subdivided plots. Five environments were evaluated: AG - agricultural greenhouse; TV35 - red shading net with 35% shading (red ChromatiNet®); TV50 - red shading net with 50% shading (red ChromatiNet®); TP35 - silver shading net with 35% shading (ChromatiNet® silver) and TP50 - silver shading net with 50% shading (ChromatiNet® silver) and four substrates: O -OrganoAmazon®; OP - OrganoAmazon® and PuroHumus®; OPSE (OrganoAmazon®, PuroHumus®, soil and manure) and OPSEC (OrganoAmazon®, PuroHumus®, soil, manure and carbonized rice husk). On the TP35 and TP50 shading nets, the C. Chinense grown on the OP substrate showed high Dickson’s quality index (DQI). The combination agricultural greenhouse (EA) and OPSE substrate promoted superior quality Capsicum chinense seedlings. The substrates OPSEC and OPSE are more affordable alternatives for the production of Capsicum chinense seedlings. Shading nets, associated with the alternative substrates, do not favor the production of quality Capsicum chinense seedlings under Amazon savanna conditions.

Abstract:

The past number of years has seen a sharp rise in the gold price. This has led to renewed activity in the gold sector and especially in refractory ore-bodies that are not economically feasible at lower gold prices. There have, historically, been a total of eleven BIOX® plants commissioned world wide with eight currently in operation. The most recent plants to be commissioned were Bogoso and Jinfeng in 2007 and Kokpatas in Uzbekistan in 2008. Design of the Bogoso BIOX® plant was started by Minproc in 2005. The design throughput of the sulphide BIOX® circuit is 820 tpd concentrate at a feed sulphide sulphur grade of 20 %. The Bogoso BIOX® plant has the largest biooxidation reactors with a live capacity of 1,500 m3 each. Plant design on the Jinfeng project started in 2005 and the engineering was performed jointly by Ausenco and Nerin. The BIOX® plant has a design capacity of 790 tpd concentrate at 9.4 % sulphide sulphur. The Kokpatas plant will be the largest BIOX® plant in the world with a Phase 1 design concentrate treatment capacity of 1,069 tpd at 20 % sulphide sulphur. The throughput will be doubled during Phase 2. Interestingly, unlike other BIOX® Plant, this plant will use a resin-in-pulp circuit for gold recovery, but the design will allow the plant to be converted to Carbon-in-pulp if required. There are currently three BIOX® projects in various stages of design or construction. This includes two expansions to existing BIOX® operations and one new BIOX® project. There are a number of major R&D projects currently under investigation with some very positive results. Most R&D is focussed on the main capital and operating cost items in the process, but there are also projects focussed purely on process optimisation and improvement.

Abstract:

An elastomeric spinal disk prosthesis design (BioFI™) with vertebral interlocking anchors has been modified using an embedded TiNi wire array. Bioinert styrenic block copolymer (Kraton®) and polycarbonate urethane (Bionate®) thermoplastic elastomer (TPE) matrices were utilized. Fatigue resistant NiTi wire was pretreated to induce superelastic martensitic microstructure. Stent-like helical structures were produced for incorporation within homogenous TPE matrix. Composite prototypes were fabricated in a vacuum hot press using transfer moulding techniques. Implant prototypes were subject to axial compression using a BOSE ® ELF3400. The NiTi reinforced implants exhibited reduction in axial strain, compliance, and creep compared to TPE controls. The axial properties of the NiTi reinforced Bionate® BioFI™ implant best approximated those of a spinal disk followed by Kraton®-NiTi, Bionate® and Kraton® prototypes. An ovine lumbar segment biomechanical model was used to characterize the disk prosthesis prototypes. Specimens were subject to 7.5Nm pure moments in axial rotation, flexion-extension and lateral bending with a custom jig mounted on an Instron® 8874. The motion preserving ligamentous nature of this arthroplasty prototype was not inhibited by NiTi reinforcement. Joint stiffness for all prototypes was significantly less than the intact and discectomy controls. This was due to lack of vertebral anchor rigidity rather than BioFI™ motion segment matrix type or reinforcement. Implant stress profiles for axial compression and axial torsion conditions were obtained using finite element methods. The biomechanical testing and finite element modelling both support existing BioFI™ design specifications for higher modulus vertebral anchors, endplates and motion segment periphery with gradation to a low modulus core within the motion segment. This closer approximation of the native spinal disk form translates to improvements in prosthesis biomechanical fidelity and longevity. Axial compressive strain induced within a TiNi reinforced Kraton® BioFI™ was found to be linearly proportional to the NiTi helical coil electrical resistance. This neural network capability delivers opportunities to monitor and telemeterize in situ multiaxis joint structural performance and in vivo spine biomechanics.

Abstract:

Reducing water use could impact existing sewer systems but this is not currently well understood. This work describes a new flow and wastewater quality model developed to investigate this impact. SIMDEUM WW® was used to generate stochastic appliance-specific discharge profiles for wastewater flow and concentration, which were fed into InfoWorks® ICM to quantify the impacts within the sewer network. The model was validated using measured field data from a sewer system in Amsterdam serving 418 households. Wastewater concentrations of total suspended solids (TSS), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN) and total phosphorus (TPH) were sampled on an hourly basis, for one week. The results obtained showed that the InfoWorks® model predicted the mass flow of pollutants well (R-values 0.69, 0.72 and 0.75 for COD, TKN and TPH respectively) but, due to the current lack of a time-varying solids transport model within InfoWorks®, the prediction for wastewater concentration parameters was less reliable. Still, the model was deemed capable of analysing the effects of three water conservation strategies (greywater reuse, rainwater harvesting and water-saving appliances) on flow, nutrient concentrations, and temperature in sewer networks. Results show through a 62% reduction in sewer flow, COD, TKN and TPH concentrations increased by up to 111%, 84% and 75% respectively, offering more favourable conditions for nutrient recovery.

Abstract:

Systemic fungal infections represent a threat to public health, and annually more than 150 million people suffer from fungal diseases. This worrisome data reflects the growing group of patients with immunocompromised conditions: due to cancer chemotherapy, organ transplanting or affected by AIDS, and the outbreaks of azoles resistant strains. Moreover, the global emergency caused by SARS-CoV-2 led to long term hospitalizations, and intubation increased the susceptibility to developing fungal infections. Therefore, now more than ever, the challenge of developing new antifungal drugs is dramatically urgent. Our research group has been interested in the great potential of guanylated compounds as new antifungal agents since 2007. During these 15 years, three series of derivatives, characterized by an amidinoureas scaffold, have been developed. The structure of these compounds is new and not shared with other antifungal drugs present on the market. Consequently, they show remarkably antifungal activity, especially among Candida strains resistant to azole drugs. The first chapter of my thesis deals with synthesizing new antifungal compounds with a macrocyclic amidinourea scaffold. Firstly, a novel compound, BM37, was synthesized through a convergent approach using the ring-closing metathesis (RCM)as a key step. Secondly, we decided to conduct advanced biological investigations of our lead compound, BM1. Consequently, we face the need to prepare this compound on a gram scale. To achieve this result, we changed the synthetic route and took inspiration from Fukuyama’s work designing a new strategy to obtain 1 gram of BM1. The second chapter of my thesis explores the design and synthesis of novel inhibitors targeting human chitinases. This project started when we investigated a putative target for the amidinoureas compounds endowed with antifungal activity. This research led us to the Chitinase family. In particular, our interest fell on human chitinases due to their involvement in chronic inflammatory lung diseases. The development of new human chitinase inhibitors, characterized by two different chemical scaffolds, is the aim of this second chapter. The former was the macrocyclic amidinoureas scaffold. Here three derivatives: BM56, BM57 and BM58, were synthesized and evaluated on human chitinases. The latter explored the chemical space related to the 6-piperazine-1-ylpyrazine-2-carboxamide, a new scaffold that emerged from a structure-based virtual screening. In this case, we synthesized a small, focused library of derivatives. The third chapter of my thesis describes my work as visiting PhD student at Uppsala University. During this period, I have been involved in the alkylation of the N position of 3-methyl indole with several cyclic ketones using a green and efficient amide coupling reagent, the TP3®. Finally, the last chapter contains chemical and biological data of all the compounds presented in the thesis.

Un film dense semi-cristallin commercial d’une polyoléfine, le TPX®, perméable mais peu sélectif et un film dense de polyimide 6FDA-m PDA obtenu par coulage, moyennement perméable mais sélectif, ont été choisis pour approfondir les mécanismes de diffusion des petites molécules (gaz et vapeurs) au sein d’une matrice polymère. Des mesures gravimétriques de sorption de vapeur d’eau et de perméation différentielle d’un gaz humidifié, ont montré que la plastification du polyimide par l’eau était correctement décrite par la relation D=D0egC. En sorption, le modèle de Park décrit convenablement l’agrégation des molécules d’eau aux fortes activités. Les coefficients de diffusion calculés à partir des cinétiques de sorption déterminées sur trois microbalances différentes ont été comparés. Avec le 6FDA-m PDA et le TPX® les mesures de sorption et de perméation des gaz CO2, N2 et O2, ont permis d’atteindre les sélectivités aCO2/N2 et aO2/N2 ainsi que les coefficients de diffusion DCO2, DN2 et DO2. La dépendance de ces derniers et de la solubilité vis-à-vis de la température et de la pression a été déterminée. La transposition sorption-perméation en dual mode a permis de corréler les résultats.

Abstract:

The advancement of virtual reality (VR) technology for educational instruction and curricular (re)design have become highly attractive and newly demanding areas of both the technology and healthcare industries. However, the quickly evolving field is still learning about each of the associated VR technologies, whether they are evidence-based, and how they are validated to decrease cognitive load and in turn increase student/learner comprehension. Likewise, the instructional (re)design of the content that the student/learner is exposed to in VR, and whether it is immersive, and promotes memorable content and experiences can influence their learning outcomes. Here the Revinax® Handbook content library that is displayed in an immersive virtual reality application in first-person point-of-view (IVRA-FPV) is contrasted with third-person point-of-view (IVRA-TPV) through VR headsets to an individual, and computer displays to many individuals along with augmented reality (AR) are evaluated as emerging advancements in the field of VR and AR.

Abstract:

Total lead (TPb) exists in Crude Wastewater (CW) from production of Lead-Acid Batteries (LABs) in water (WPb) and solid phase (SPb) as colloids and suspended solids. Sludges produced in chemical treatment of these wastewater were dewatered in Chamber Pressure Press (CPP). Samples of dewatered sludges (Ss) were analyzed with Toxicological Characteristic Leaching Procedure (TCLP) to determine concentration of Pb in the extract (Ex(TCLP)). Selected sludges were also analyzed using Tessier’s procedure for fractions. Concentration of lead in filtrates (Fs) as well as in the sludges were different, depending on the mechanisms involved in converting soluble lead to its less soluble forms. Sludges produced in chemical treatment with 10% NaOH and Lime Milk (LM), CaO or Ca(OH)2, followed by coagulation with (Ixonos Na3T ®) contained lowest concentration of lead. The TPb in filtrates below 0.4 mg/L at pH > 8.90±0.3, and Ex(TCLP) of less than 5.0 mg/L were obtained in this treatment. Potential recovery of lead from sludges have been investigated.

Abstract:

Two major new Waste-To-Energy (WTE) Projects have received Air Construction Permits under the Prevention of Significant Deterioration (PSD) program during the past two years and a third is scheduled to receive its permit prior to NAWTEC 20. These new facilities are being required to operate with significantly lower emissions of nitrogen oxides (NOx) and other major air pollutants than similar existing US facilities. This paper will explore the permitting process on these three projects and the divergent approaches being taken by the applicants to meet the stringent emission requirements imposed by the PSD permits. The Palm Beach County (Florida) Renewable Energy Facility No. 2 (PBREF No. 2) will be a three unit, 3,000 ton per day (tpd) mass burn facility which will utilize Selective Catalytic Reduction (SCR) systems similar to that used in many recent European WTE facilities for NOx control. The Fairfield (Maryland) Renewable Energy (Fairfield) and Aercibo (Puerto Rico) Renewable Energy (Aercibo) Projects are each two unit, 2,106 tpd Refuse Derived Fuel (RDF) facilities which will utilize regenerative SCR (RSCR®) systems. This will be the first time RSCR® has been used in a WTE application. All three permits require achievement of a NOx emission rate of 45 parts per million by volume at 7% O2 dry basis (ppmvd). PBREF No. 2 and Fairfield received PSD permits from delegated state programs prior to the new Greenhouse Gas (GHG) and condensable PM2.5 permitting rules going into effect at the beginning of 2011. Aercibo is being permitted by United States Environmental Protection Agency (EPA) Region II and will reflect new GHG and condensable PM2.5 permitting rules. This paper discusses the approach to the Best Available Control Technology (BACT) and Lowest Achievement Emission Rate (LAER) determinations and differences in final permit requirements.

Abstract:

Abstract This research is aimed at proposing an enhanced re-entrant hexagonal structure and examining its auxetic behavior in compressive or tensile load conditions. An integrated experimental and finite element analysis (FEA) approach was used to investigate the behavior of the proposed structures in combination with polymeric materials (thermoplastic polyurethane (TPU) materials such as Ninjaflex® and Semiflex®). We focused on the effect of nonlinearity of the structure on the overall stiffness and shock-absorption performance of the body protection pads. FEA models were used to examine how the stiffness and Poisson’s ratio are affected by static load conditions and also how the dynamic loads are transmitted through the auxetic structure. The static FEA models were verified through experimental testing. Advanced additive manufacturing (3D printing) techniques such as Fused Deposition Modeling (FDM) were used to build fixtures and prototypes of the auxetic polymeric structures. Structural stiffness and Poisson’s ratio were examined not only in tensile loading condition but also in compression. Axial and lateral deformations were measured for given axial forces on the experimental model, and the measured values of Poisson’s ratio were compared with the computational results. It was shown that the enhanced re-entrant hexagonal structures had nonlinear behavior, which could be a useful property for developing body protection pads and stiffness-varying structures.

Abstract:

A greenfield Refuse Derived Fuel (RDF) facility in Alliance Ohio will process 2,400 Tons Per Day (TPD) of Municipal Solid Waste (MSW) and Construction & Demolition Debris (C&D). The Ohio EPA has issued the final air permit for the facility. There will be two equipment trains to handle the material each consisting of Riley Power’s Advanced Stoker™ boiler, Turbosorp® dry scrubber, and Regenerative Selective Catalytic Reduction (RSCR®) nitrogen oxides (NOx) control system. The key parts of the “chute to stack” equipment represent a significant advancement in technology when compared to past facilities, as demonstrated by the designation by the State of Ohio as an “Advanced Energy Project”. The Riley Advanced Stoker™ boiler has unique design features to ensure high efficiency, corrosion resistance, and fuel flexibility while at relatively low cost. The use of the Turbosorp will result in lower emissions of lead, other volatile heavy metals, and mercury than for a typical spray dryer/baghouse (SDA) system. Acid gas removal is also superior to an SDA system while utilizing less lime reagent and power. The RSCR follows the Turbosorp as a “low dust” SCR but with auxiliary energy consumption about 85% lower than a typical low dust, tail end SCR. The RSCR will reduce NOx and Carbon Monoxide (CO) emissions to low values when compared to other facilities producing energy from waste. This paper will describe the design basis for the system including fuels to be processed, steam flow and conditions, and emissions. A detailed description of the technologies will also be presented.

Abstract:

Hydrophilic coatings applied to guidewires or catheters, lower friction of the device thus improves handling and reduces damage to the vessel walls during access, delivery and retrieval. Peripheral guidewires typically consist of a polymer jacket, basecoat and topcoat. The polymer jacket is highly radiopaque for fluoroscopy visualization. Basecoat adheres to the polymer jacket and hydrophilic topcoat. Basecoat and topcoat play important roles towards coating device durability and lubricity. Water Loving Coatings (WLC) are the first developed 510(k) clearance guidewires utilizing epoxy polyurethane technology. Coatings are non-hemolytic and non-cytotoxic. WLC are advances toward glycidyl carbamate (GC) resins. Linear Glycidyl Carbamates have shown excellent flexibility based off structure property relationships [1]. Water dispersible GC (WD-GC) oligomers have been prepared by additions of poly(ethylene glycol) methyl ether (m-peg) to isocyanurate and biuret, then end capped with glycidol [2]. WLC technologies are lubricious and durable water dispersible polyurethane or polyurea glycidyl carbamates [3]. Modified Hyaluronate with WD-GC oligomers have shown increases in lubricity of Guidewires when used with a catheter [4]. WLC coatings have been applied to a micro-wire to reduce endothelial mechanical lining damage [5]. Common thermoplastic urethanes (TPU), similar to WLC morphology, used in the medical industry, are: Biomer and Lubrizol’s Pellethane®, Tecoflex™ and Estane™. Biomer consists of 4,4′-Methylenebis(phenyl isocyanate) (MDI), Ethylenediamine (EDA), and Polytetramethylene diol (Poly THF). Pellethane consists of MDI, 1,4-Butanediol (BDO) and Poly THF. Tecoflex consists of 4-4′-methylenebis (cyclohexyl isocyanate) (H12MDI), BDO and Poly THF. Medical grade Estane is an ester of adipic acid with BDO for soft segments and MDI and BDO for hard segments. TPU structure and morphology dictates polymeric properties.

Abstract:

Abstract The main task of the present paper is the development and the implementation of a suitable analytical model to correctly capture rolling bearing radial stiffness, particularly nearby the critical speeds of the investigated rotor-bearings system. In this paper, such bearing non-linear stiffness model is applied to air bladeless turbines (or Tesla turbines) high speed rotors, in order to assess their global rotordynamic behavior when they are mounted on hybrid ball bearings. In order to properly investigate all the issues related to critical speeds identification, an adequate number of tests was performed by exploiting an experimental air Tesla turbine prototype located at TPG experimental facility of the University of Genoa. The correlation between experimentally detected flexural critical speeds and their numerical predictions is markedly conditioned by the correct identification of ball bearings dynamic characteristics; in particular, bearings stiffness effect may play a significant role in terms of rotor-bearings system natural frequencies and therefore it must be accurately assessed. Indeed, Tesla turbine rotor FE model previously employed for numerical modal analysis relies on rigid bearings assumption and therefore it does not account for bearings stiffness overall contribution, which may become crucial in case of “hard mounting” of rotor-bearings systems. Subsequently, high-speed air Tesla rotor is investigated by means of an enhanced FE model for numerical modal analysis within Ansys® environment, where ball bearings are modelled as springs whose stiffness is expressed according to non-linear analytic model implemented in Matlab®. The obtained results in terms of rotor-bearings system modal analysis exhibit an improvement in experimental-numerical results correlation by relying on such ball bearing stiffness model; moreover, beam-based FE model critical speeds predictions are coherent with experimental evidence and with respect to the previously employed FE model based on solid elements it is characterized by lower computational time and it is more easily interpretable. Thus, such experimentally validated numerical model represents a reliable and easily adaptable tool for high-speed rotating machinery critical speeds prediction in practical industrial application cases.
