title: Disparities In The Use Of Drug-eluting Stents For Diabetic Patients With ST-elevation Acute Myocardial Infarction Assisted In the Public versus Private Network - VICTIM Register

description: Abstract Background: Primary angioplasty (PA) with placement of either bare metal or drug-eluting stents (DES) represents the main strategy in the treatment of ST-elevation myocardial infarction (STEMI). Diabetic patients, however, represent a special population in STEMI, with high rates of restenosis and unfavorable clinical outcomes, and with the use of DES, level of evidence A and indication class II, being indicated to reduce these damages. Objectives: To evaluate the DES rate of use in patients with STEMI and in the subgroup of diabetics assisted in the public versus private health network in Sergipe. Methods: This is a population-based, cross-sectional study with a quantitative approach using the data from the VICTIM Register. These were collected in the only four hospitals with capacity to perform PA in Sergipe, from December 2014 to March 2017. Results: A total of 707 patients diagnosed with STEMI were evaluated, of which 589 were attended at SUS and 118 at the private network. The use of DES in PA was lower in SUS compared to the private network in both the total sample (10.5% vs 82.4%, p&lt;0.001) and in subgroup diabetic patients (8.7% vs 90.6%, p &lt; 0.001), respectively. In all hypotheses tested, the level of significance was 5% (p &lt; 0.05). Conclusions: The study reveals a disparity in the use of DES during the performance of PA between the public and private network, both in the total sample and the subgroup for diabetics, with lower rates for SUS users, demonstrating the challenges that need to be overcome in order to achieve quality improvements of the services provided.

title: Eco-efficient mortars with simultaneous incorporation of phase change material and fly ash

description: ABSTRACT Nowadays, the construction industry is the one of the main European sector responsible for the higher levels of energy consumption, raw materials extraction and waste production. Increasingly the consumption of energy from renewable sources and reusing industrial wastes is the only way to minimize this problem for the environment and society. The simultaneous incorporation of phase change materials (PCM) and fly ash (FA) in mortars allow increase the energy efficiency in buildings and decrease the amount of the raw materials extraction and waste materials landfilled. The development of mortars with incorporation of PCM and fly ash contributes to a significant improvement of the comfort parameters inside buildings and in the environment. The PCM allow regulating the temperature inside buildings using only solar energy as a resource, decreasing the air conditioning needs. The PCM has the capability to absorb and release energy for the environment. The main purpose of this study was the physical, mechanical and thermal characterization of mortars with incorporation of PCM and FA. It was concluded that the simultaneous incorporation of PCM and FA leads to homogenous and suitable mortars, with good physical and mechanical properties and an increased thermal behavior when compared to the mortars without incorporation of PCM and only with incorporation of PCM.

title: Esquema Explícito Semi-Analítico para a Solução da Equação da Onda Unidimensional com Condições de Contorno Naturais

description: ABSTRACT This paper discusses the development of an semi-analytical explicit scheme for solving the non-homogeneous one-dimensional wave equation. A space-time mesh was constructed through the incremental relation c Δ t = Δ x, such that control volume were formed from the characteristic lines of said equation. Schemes were developed from the integral form of the conservation law on these control volumes. They have the property of null local truncation error, even in cases not homogeneous or generalized solution. The method facilitates the inclusion of the initial and boundary conditions, also inserted without the need for approximation techniques. Considering the developments and numerical experiments performed, we conclude that the proposed scheme is an excellent numerical technique, with great accuracy and robustness to solve the one-dimensional linear wave problem.

title: Replacement of fishmeal and fish oil with vegetable meal and oil in feedstuffs used in the growing phase of the Pacific white shrimp Litopenaeus vannamei, in biofloc systems

description: ABSTRACT The objective of this work was to evaluate the effect of the substitution of fishmeal and fish oil with soy protein concentrate and soybean oil on survival, growth and body composition of shrimp (Litopenaeus vannamei) produced in biofloc system (BFT). Five diets were formulated to be isoproteic and isoenergetic with different levels of substitution of fishmeal and fish oil with soy protein concentrate and soybean oil. The treatments were named as: 0% (without substitution), 25%, 50%, 75% and 100%. The diets were formulated to contain approximately 35% protein and 8% lipids. The experiment was conducted for 49 days, with juveniles with initial weight of (2.93±0.83g) in a biofloc system (BFT). No significant differences were found between treatments up to 75% of substitution for the variables of weight gain, feed conversion ratio, and survival. The 100% substitution treatment showed a lower specific growth rate. The present study suggests fish meal and fish oil can be substituted in up to 75% for soy protein concentrate and soybean oil, without harming the development of the shrimps when reared in biofloc system.

title: Estudo das Trincas Retas com o Método dos Elementos de Contorno, a Função de Green Numérica e a Técnica da Dupla Reciprocidade

description: ABSTRACT In recent years, the Boundary Element Method (MEC) has been applied successfully to mechanical problems of linear elastic fracture mechanic (LEFM) involving static and dynamic cases. To solve problems with domain actions (for example: gravitational forces, transient problems with speeds and accelerations, etc.) via BEM, Nardini and Brebbia presented in 1982 the Technique of the Dual Reciprocity (DR), initially with the intention of solving transient problems using static, but has proved to be quite adequate and effective in solving problems with actions of domains. Based on the above, this paper presents complementary studies initiated by Vera-Tudela in 2003, using the Technique of Numerical Green’s Functions (FGN), together with the Dual Reciprocity. The development of these three formulations for the analysis of mechanical problems fractures under the effect of domain charges constitute a step forward in addressing the problems BEM. Although the use of Dual Reciprocity technique in fracture mechanics problems is not recent, their joint implementation with the Numerical Green Function represents a novelty in research and with the advantage of not having to do the discretization of the surfaces of the cracks because the integrations are made only on the contour of the problem. Two examples are presented, and the results compared with the reference literature and with the theory show and efficiency of the formulation.

title: Identification of roselle varieties through simple discriminating physicochemical characteristics using multivariate analysis

description: Abstract The objective of this work is to study the feasibility of a more objective and rigorous classification of the calices of Hibiscus sabdariffa based on their physicochemical profile. To do so, 19 analyses were carried out on 4 varieties of calices cultivated in Senegal: Vimto, Koor, Thaï and CLT92. Principal component analysis results showed that 15 physicochemical and biochemical parameters could be potentially used to discriminate the varieties of calices. Polyphenolic and anthocyanin contents were anti-correlated to protein content and could be used to differentiate the Vimto/CLT92 and the Koor/Thaï varieties. Within these two clusters, pH and lipid content could discriminate each variety. Finally, factorial discriminant analysis showed that total anthocyanin content, lipid content and chromaticity C* were the 3 parameters enabling the most efficient classification of calices according to variety and led to 100% classification accuracy.

title: Chemo-characterization and optimization of macro and micro nutrients for exopolysaccharides and mycelia growth in pleurotus tuberregium (RUMPH, EX FR)

description: Abstract Exoploysaccharides are potential nutraceutic, probiotic, phamarceutic and cosmesceutic natural products in fungi. Pleurotus tuberregium is an underutilized tropical fungus that is useful as food with recent reports of pharmacological activities. The present study evaluated and characterized environmental conditions and nutrients for optimal P. tuberregium mycelia growth (PtMG) and exopolysaccharides (PtEPS) production using batch culturing and diverse chemometric methods, respectively. Rank-sum analysis categorized the assessed conditions and nutrients into six stimulatory classes and most suitable nutrients and conditions for PtMG and PtEPS were co-identified with analysis of variance. Glucose, yeast, sodium chloride (NaCl) and tricalcium diphosphate (Ca3(PO4)2) were excellent stimulant (ES) for both PtEPS and PtMG under culturing condition of pH 6 at 30 °C for 15 d. The Chemo-phene trees generated by cluster analysis allowed visualization and clear-cut demarcation of the six stimulatory classes. The information embedded in the present study is useful for improving and developing culturing media for optimal PtMG and PtEPS yields, enabling maximal P. tuberregium utilization as food and medicine.

title: Effects of Modified Atmosphere Packaging (MAP) and slaughter age on the shelf life of lamb meat

description: Abstract The shelf life extending effect of different modified atmospheres packages (MAP): vacuum (MAP-1), 69.6% N2 + 30% CO2 + 0.4% CO (MAP-2) and 70% O2 + 30% CO2 (MAP-3) on lamb meat at two slaughter ages (4 and 8-month-old) was assessed. pH decreased as slaughter age (SA) increased, and increased during longer storage time (ST), with no MAP effects. Lamb meat stored in MAP-1 and MAP-3 showed greater drip loss than that stored in MAP-2. Shear force was not influenced by SA and MAP treatments, but decreased during ST. Meat from 8-month-old lambs packaged in MAP-3 at longer ST resulted in lipid oxidation increase. MAP-2 enhanced color saturation and lamb meat redness, whereas MAP-3 showed lowest redness and chroma values, and highest aerobic psychrotropic count. Meat from 4-month-old lamb stored in MAP-3 presented shortest shelf life based on psychrotropic bacteria growth. The association of higher SA with high O2 MAP proved to compromise oxidative stability of lamb meat, adversely affecting its shelf life. Vacuum and CO packaging showed similar effects on lamb meat preservation; however, CO had advantage in maintaining fresh red color of meat.

title: Y-shaped and fruiting wall peach orchard training system in subtropical Brazil

description: ASBTRACT Peach as commercial crop in Brazil is usually grown in open vase training system. However, in the 1970s large orchards changed to the Y-shaped system and higher density of plants. This system is the most used in São Paulo state because it allows orchard densification. However, the longevity of the trees is reduced from 15 to 8 years being the excessive exposure of internal branches to solar radiation the main reason for the reduction. Aiming to offer new alternatives of training system for peach, an experiment was carried out to evaluate the fruiting wall in comparison to Y-shaped, using the cultivar Tropic Beauty budded onto cultivar Okinawa. Ten plants by treatment were used as repetition and microclimatic equipment was installed inside the plant to measure temperature and solar radiation. Values of soluble solids (°Brix) were 9.64 to fruiting wall and 9.59 to Y-shaped, not statistically different. However most of fruit physicochemical characteristics were favorable to the fruiting wall system: fruit weight (g) – 97.56 and 90.44; pulp yield (g) – 92.42 and 85.70; pulp firmness (Kg∙cm–2) – 4.27 and 3.50; titratable acidity (g citric ac.∙100 ml–1) – 0.76 and 0.71; and ratio – 12.79 and 13.58, respectively to fruiting wall and Y-shaped. Solar radiation transmission and maximum daily temperature values for the Y-shaped were higher when compared to fruiting wall at harvest. The obtained data show that the fruiting wall training system could be an alternative to Brazilian’s growers for producing superior fruit quality without yield reduction.
