title: MODEL PREDICTIVE CONTROL FOR PRODUCTION OF ULTRA-LOW SULFUR DIESEL IN A HYDROTREATING PROCESS

description: ABSTRACT There is a continual desire around the world to reduce the sulphur content of diesel fuel to ultra-low levels (below 10 ppm) due to environmental concerns and the intention of improving air quality and lowering harmful exhaust emissions of diesel engines. In this work, a hydrodesulfurization unit fed with multiple diesel streams was addressed using a phenomenological mathematical model aiming to produce Ultra-Low Sulfur Diesel (ULSD). A three-phase model of a trickle-bed reactor was considered. A model-based predictive control strategy (MPC) was implemented with the objective of controlling the sulfur concentration at the exit of the reactor, manipulating the flow rates of the oils entering the system, the superficial velocity of the gas and the temperature of the load in the presence of disturbances in the concentration of organic sulfur compounds in the fed oils. It was observed that the control strategy reduced the contaminant content to the specification range of diesel S10.

title: Influence of socioeconomic factors on the perception of cochlear-vestibular symptoms and adherence to the treatment of congenital hypothyroidism

description: Abstract Objectives: to verify if there is an association between socioeconomic factors and adherence to treatment in congenital hypothyroidism and to verify if there is an association between socioeconomic factors and vestibulocochlear symptoms noticed by parents/caregivers of children diagnosed with congenital hypothyroidism. Methods: a cross-sectional, exploratory and descriptive study, with a convenience sample. The sample consisted of 108 children with clinical and laboratory diagnosis of congenital hypothyroidism, of both sexes, aged ≥ 5 years. The researchers applied a structured questionnaire to parents/caregivers, consisting of closed and objective questions about the presence or absence of tinnitus, hearing loss and dizziness/vertigo in children with congenital hypothyroidism. Results: There was no association between socioeconomic factors and adherence to treatment or perception of cochlear-vestibular symptoms. Conclusions: socioeconomic factors did not influence treatment adherence or perceived cochlear-vestibular symptoms by caregivers of children with congenital hypothyroidism.

title: Incentives for technological innovation: a study of the public policy of tax exemption in Brazil

description: Abstract The goal of this paper is to explain relations between investments in Research and Development - R&D and innovation’s outcomes between the 2009s and 2013s in companies that are encouraged by the Lei do Bem (Good Law), which regulates tax incentives for technological innovation. Econometric Logit models were estimated for fixed effects. The analysis results indicate that the probability of firms presenting innovations in general (in products, processes or services) or only in products depends on the size of the company and the amount invested in R&D, particularly it depends on the investment in human resources - HR. On the other hand, the chances of firms innovate in process are limited to the size of the company, the spending specifically to develop HR programs. The results confirm that investments in R&D from the beneficiaries produce innovation’s outcomes.

title: Adulterants in crack cocaine in Brazil

description: Abstract Introduction Brazil is the world’s biggest consumer of crack cocaine, and dependence is a major public health issue. This is the first study to investigate the prevalence of potentially harmful adulterants present in hair samples from Brazilian patients with crack cocaine dependence. Method We evaluated adulterants in hair samples extracted by convenience from 100 patients admitted at the 48 hour-observation unit of Centro de Referência de Álcool, Tabaco e Outras Drogas (CRATOD), Brazil’s largest center for addiction treatment. A cross-sectional analysis was performed with the data obtained. Results Adulterants were found in 97% of the analyzed hair samples. The most prevalent adulterant was lidocaine (92%), followed by phenacetin (69%) and levamisole (31%). Conclusion Adulterants were widely prevalent in hair samples from crack users treated at CRATOD: at least one adulterant was present in virtually all the hair samples collected. This points to a need to monitor adverse effects in the clinical setting in order to provide this high-risk group of patients with prompt and effective care related to the acute and chronic complications associated with these adulterants.

title: Brazilian energy-related climate (in)action and the challenge of deep decarbonization

description: Abstract We present the challenge of deep decarbonization, the state of play of major economies regarding it, Brazilian outcomes compared to its peers and political struggles that help explain these outcomes. By identifying key actors, their interests and how they interact in domestic politics in issues that are key to deep decarbonization, we explain why Brazil, despite the potential to be ahead of its peers, has been moving backwards, and how Brazilian stances in the climate regime are influenced by it. The research is based on a qualitative analysis of extensive empirical data (primary and secondary sources).

title: GRAPHICAL REPRESENTATION ANALYSIS OF COMPLEMENTARY CIVIL PROJECTS USING "CAD 2D", "BIM" AND "RA" AND IDENTIFICATION OF INTERFERENCES

description: Abstract Technical graphic representation presents problems concerning the reduction of dimensionality from 3D to 2D. AEC (architecture, engineering and construction) projects usually adopt the top view paradigm with two-dimensional orthogonal projection. Recently, three major changes in technical representation were the alteration of orthogonal projection into a three-dimensional perspective view, inclusion of oriented object programing as in BIM (Building Information Model) and the interactions with AR (augmented reality). In this context, the present research evaluates the proposal of symbology based on color Hue as done in Cartography and the impact of three-dimensionality of the symbol in the identification of incompatibilities in a project of a residential building. An application of the visual variable color hue was proposed improve readability to representations and evaluations were performed with expert users, using representations in CAD 2D, BIM and AR in top and perspective views. Results indicate the color hue improve the cognitive process of read, interpret and find incompatibilities in civil projects, while the change of point of view contribute to interaction and manipulation in virtual environments. Both shows significance higher than 6% in ANOVA tests.

title: Left Ventricular Reconstruction Surgery in Candidates for Heart Transplantation

description: Abstract Objective: To report our center’s experience in the surgical treatment of ventricular reconstruction, an effective and efficient technique that allows patients with end-stage heart failure of ischemic etiology to have clinical improvement and increased survival. Methods: Observational, clinical-surgical, sequential, retrospective study. Patients with ischemic cardiomyopathy and left ventricular aneurysm were attended at the Heart Failure, Ventricular Dysfunction and Cardiac Transplant outpatient clinic of the Dante Pazzanese Cardiology Institute, from January 2010 to December 2016. Data from 34 patients were collected, including systemic arterial hypertension, ejection fraction, New York Heart Association (NYHA) functional classification (FC), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II value, Society of Thoracic Surgeons (STS) score, ventricular reconstruction technique, and survival. Results: Overall mortality of 14.7%, with hospital admission being 8.82% and late death being 5.88%. Total survival rate at five years of 85.3%. In the preoperative phase, NYHA FC was Class I in five patients, II in 18, III in eight, and IV in three vs. NYHA FC Class I in 17 patients, II in eight, III in six, and IV in three, in the postoperative period. EuroSCORE II mean value was 6.29, P≤0.01; hazard ratio (HR) 1.16 (95% confidence interval [CI] 1.02-1.31). STS mortality/morbidity score mean value was 18.14, P≤0.004; HR 1.19 (95% CI 1.05-1.33). Surgical techniques showed no difference in survival among Dor 81% vs. Jatene 91.7%. Conclusion: Surgical treatment of left ventricular reconstruction in candidates for heart transplantation is effective, efficient, and safe, providing adequate survival.

title: Characterization of pepper accessions using molecular markers linked to pungency and SSR

description: ABSTRACT Peppers of the genus Capsicum are of great socioeconomic importance, being pungency trait their main attraction. Pungency characterization, genetic distance estimates and population structure analysis of the accessions belonging to germplasm banks are important for parent selection which allows to obtain superior progenies. Therefore, the aims of this study were: i) evaluate 81 accessions of the Capsicum spp. Germplasm Bank of Universidade Federal de São Carlos (BGC-UFSCar) with molecular markers linked to pungency; ii) estimate the genetic diversity among accessions of the BGC-UFSCar using microsatellite markers (SSR); and iii) evaluate the efficiency of these markers in the distinction among species of Capsicum spp. We noticed that pun11 and SNP molecular markers were efficient in predicting the pungent phenotype of BGC-UFSCar accessions in 84.85% and 95.59%, respectively. From a total of 13 amplified microsatellite markers, seven were polymorphic and efficient to discriminate species of Capsicum genus, both through genetic diversity analysis and population structure analysis, which showed three subpopulations. The molecular markers used in this study are useful tools for breeding programs since they were able to characterize and discriminate Capsicum spp. species at DNA level. Information obtained with molecular markers can assist in the selection of contrasting parents for future breeding programs.

title: Identifying public policies: Public Defenders and men who broke the Maria da Penha Law

description: Abstract The evaluation of the assistance services provided by the Public Defender’s Office allows to identify demands and problems for public policies. This article presents the results of an observation research that evaluated the services of the Núcleo de Atendimento ao Homem Autor de Violência Doméstica e Familiar (Neah) (Support Center for men who committed Domestic and Family Violence), considering the testimonies of people assisted by the institution and their partners. From the results, it is possible to identify future actions and public policies aimed to prevent, promote self-reflection, and change the perception related to aggressive men. The results of the empirical observation highlight the paradox of the public policies of assistance to men accused of domestic violence, since the spouses’ evaluation about the police assistance and the assistance services offered by the DP-PA shows a dissatisfaction with the results of the services their partners receive. Men who participated in the therapeutic group expressed during the interviews that they experienced a change in behavior toward their spouses and their view about women.

title: Sediment production and soil water infiltration under different simulated rainfall characteristics

description: ABSTRACT The study was carried out to evaluate sediment production, water infiltration and surface runoff in an Ultisol under simulated rainfalls with similar erosivity, but different combinations of intensity (Int) and duration (Dur). The rainfalls were applied after soil tillage in the period from August to September 2017, in Seropédica, RJ State, Brazil. Using a computer program, the treatments were defined from the erosivity calculated for a rainfall with intensity of 60 mm h-1 and duration of 60 min, resulting in the other combinations of Int and Dur: 44.5 mm h-1 and 106 min; 53.5 mm h-1 and 78 min; 66.9 mm h-1 and 48 min; and 76.5 mm h-1 and 38 min, in a completely randomized design with five repetitions. Sediment production varied from 2.17 to 6.11 g m-2, respectively, in the treatments with Int 53.5 mm h-1 and Dur 78 min and Int 44.5 mm h-1 and Dur 106 min. Stable infiltration rate (mm h-1) were 21.6, 37.7, 31.4, 29.5, and 22.4, respectively, in the treatments Int 44.5 mm h-1 and Dur 106 min; Int 53.5 mm h-1 and Dur 78 min; Int 60.4 mm h-1 and Dur 60 min; Int 66.9 mm h-1 and Dur 48 min; and Int 76.5 mm h-1 and Dur 38 min. The different combinations of intensity and duration of rainfalls with similar erosivity change sediment production, but do not significantly influence surface runoff and water infiltration in the soil.
