title: Evolutive characteristics of Prosopis spp.: cytogenetic, genetic and hybridizations

description: Abstract Prosopis is a primitive genus in the Mimosoid’s clade characterized by disjunctions in its distribution areas and the difficulty in establishing its phylogeny. This paper presents an updated literature review on the evolutionary, cytogenetic, genetic and hybridization characteristics of the genus. The available data suggest that it diverged early in several major lineages, although in some of them recent episodes of partial speciation have occurred. Genetic diversity within and between populations depends on the reproductive system and adaptative strategies, among other factors. Populations’ structure also sets restrictions to evolutive processes leading to the increasing adaptation to the environment and/or specific differentiation. It is an essentially diploid genus (2n = 28) never the less polyploidy and frequent processes of interspecific hybridization and introgression have been informed. High genetic and chromosomal similarity between species of the genus allows the generation of viable hybrids, reinforcing the idea that some species are evolutionarily active and highlights the difficulties this causes in the taxonomic treatment and the phylogeny of the group.

title: Animal welfare in experimental orthopedic surgery of dogs: an analysis of the Brazilian view

description: ABSTRACT: The aim of this paper was to conduct a bibliometry search about Brazilian scientific publications that describe experimental orthopedic surgeries in dogs. It was analyzed 14 publications, and there was wide variation in the number of experimental animals, showing that there is no consensus on the appropriate number for science experiment with dogs. Most articles had been reviewed by an ethics committee (13/14, 92.85%) and only two articles (2/14; 14.28%) did not report the use of analgesic protocol. Among analgesics, morphine was the most widely used, noted in seven studies (7/14; 42.85%). In six of the articles (6/14; 42.85%), the final destination of animals was not informed, but in four experiments (4/14; 28.57%) the dogs were euthanized. In four studies (4/14; 28.57%) the animals were sent for adoption. In conclusion, the ethics in animal research in Brazil has advanced, but is necessary proper planning in sample size.

title: Update in Heart Rhythm Abnormalities and Indications for Pacemaker After Transcatheter Aortic Valve Implantation

description: Abstract Objective: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI) and indications for permanent pacemaker implantation (PPI) were reviewed, which aren't well established in the current guidelines. New left bundle branch block and atrioventricular block are the most common electrocardiographic changes after TAVI. PPI incidence ranges from 9-42% for self-expandable and 2.5-11.5% for balloon expandable devices. Not only anatomical variations in conduction system have an important role in conduction disorders, but different valve characteristics and their relationship with cardiac structures as well. Previous right bundle branch block has been confirmed as one of the most significant predictors for PPI.

title: Study of the kinetics of the dissolution of the wastes residual of the borateras industries with solutions of glycerin

description: ABSTRACT In this paper the dissolution kinetics of industrial boron wastes residual with glycerin solutions (C3H8O3), effluent from the biodiesel industry, with the aim of enhancing the utilization both wastes, were investigated. It is based on the complexation of boron with the polyol. The dissolution is carried out in a batch reactor at atmospheric pressure. The effect of the following parameters is investigated: reaction temperature, concentration of glycerin, and solid/liquid ratio on the dissolution rate of the industrial wastes. It is shown that the dissolution rate of industrial boron wastes in glycerin solutions increases with increasing the concentration of glycerin and the reaction temperature and decreases with increasing the solid/ liquid relation. The best working conditions are as follows: temperature 80 °C, glycerin concentration 0,4 M and solid/liquid ratio of 0,1 g / ml. Under these conditions the transformation of industrial boron waste is higher to 17%. The apparent activation energy was determined, 7,72 kJ / mol, consequently the dissolution of the wastes is controlled by diffusive mechanisms.

title: Comparative analysis on delta ferrite determination for austenitic stainless steels

description: ABSTRACT In the welding of austenitic stainless steels, the determination of delta ferrite (δ-ferrite) is very important to assess the susceptibility of weld metal to hot cracking, one of the major problems related to weldability, metallurgical and mechanical behavior of this type of steels. The determining δ-ferrite in the weld metal can be performed with predictive methods from the chemical composition of weld metal provided by the welding consumable (the diagram of Schaeffler, Delong, WRC 1988, WRC1992), by metallography and using nondestructive testing technique by magnetic determination of ferrite. This paper presents a comparative analysis of the predictive determination of δ-ferrite and the magnetic method using austenitic stainless electrodes for SMAW process using different classifications and diameters. The filler metals used correspond to different batches of such consumables and it has used a standardized methodology for magnetic determination. The correlation between the two methods seems to work best for NF values between 4 and 8. Errors and the correlation between the two methods applied to determine NF are not acceptable when the electrodes deposit solder metals with high NF values, greater than 18.

title: Evaluation of the applicability of a probiotic strain of Saccharomyces cerevisiae in cereal bars

description: Abstract The objective of this study was to evaluate the use of a probiotic yeast in the production of a cereal bar, contributing to the production of an innovative functional food. For this, a chocolate mixture inoculated with 8 log10 viable yeast cells was spread onto the surface of the cereal bar. The physical, chemical and sensory parameters of the probiotic cereal bar were verified and the number of cells quantified up to the death of the yeast cells. The results showed that the presence of the yeast did not negatively affect the physical and chemical properties of the cereal bar. No preference was observed in relation to the bars without probiotic yeast for the sensorial parameters evaluated. The yeast remained alive (10 4 cells/g) for 45 days.

title: Passifloraceae sensu stricto in the Serra do Brigadeiro State Park, Minas Gerais, Brazil

description: Abstract The present study goal was to survey the taxonomic diversity of Passifloraceae sensu stricto in the Serra do Brigadeiro State Park (PESB), Minas Gerais and to investigate the ecological aspects related to the distribution, state of conservation and occurrence of the species in different altitude classes within the study area. Eleven species of the genus Passiflora were identified: P. alata, P. amethystina, P. capsularis, P. edulis, P. filamentosa, P. mediterranea, P. miersii, P. porophylla, P. rhamnifolia, P. speciosa and P. tetraden, of which four are new records for the PESB (P. alata, P. capsularis, P. filamentosa and P. rhamnifolia). Most of the species are considered endangered at a regional level, with exception of P. filamentosa and P. miersii, classified as "Data Deficient", and P. speciosa and P. mediterranea, considered as "Least Concern". Only P. alata and P. rhamnifolia reached the highest elevations in the area, in campos de altitude (1.700-1.800 m).

title: Poaceae in a Brazilian floodplain: spatial distribution and conservation

description: Abstract With 94 species, Poaceae is one of the largest botanical families of the Upper Paraná River Floodplain (PIAP) and its environs, located between 22º38’-22º57’S and 53º5’-53º36’W, and covering areas of the Brazilian states of Mato Grosso do Sul and Paraná. Seasonally flooded, PIAP is part of the The Environmental Protection Area of the Islands and floodplains of the Paraná River (APA-IVRP) and State Park of the Ivinhema River Floodplain (PEVRI). Aiming to improve the botanical and ecological knowledge of the area and therefore contribute to its conservation, we studied the distribution pattern of the grasses of PIAP and its environs. For the grasses of PIAP we considered: phytophysiognomy, light exposure, photosynthetic pathway, water condition of the substrate where they preferably occur, classification of the morphovegetation, and the absolute and relative frequencies. The results show that the species are distributed according to the geomorphological configuration of the PIAP, which are presented here in two schematic profiles.

title: Impact of Alloy Composition and Thermal Stabilization on Martensitic Phase Transformation Structures in CuAlMn Shape Memory Alloys

description: Alloys of CuAlMn are known as cheap, high strength shape memory alloys with an excellent damping capacity within their austenitic-martensitic phase transformation, compared to alloy systems like NiTi, CuZnAl or MnCu. But CuAlMn alloys have disadvantage due to generation of voids by a high shrinkage which further increases the existing proneness to stress cracks during rapid cooling. Alloying grain refining elements improves the stress crack resistance and enables a wide range of rapid quenching parameters which are needed to control the temperature of martensitic phase transformation. Additionally, the elements itself influence the in- or decreasing of the phase transformation temperature and the SMA effects. Furthermore, some of these elements can reduce the internal friction indirectly by decomposing areas of metastable martensite into its stabilized forms, where no transformation occurs. This thermic stability can be calculated by the concentration of valence electrons in a unit cell. The proneness to ageing is controlled by multistep heat treatments. Annealing and rapid quenching into the area of martensitic phase transformation maximize the generation of point defects. A high amount of point defects contradicts the negative effect of pinning. It also preserves the material from extreme brittleness. The influences of these effects are shown at single cantilever bending beams by elastic strain amplitude (ε = 12E-4) depending measurements of internal friction at natural frequency along the ageing at room temperature (293 K) up to 2500 h. The samples are annealed at 1123 K for 15 min (CuAl14Mn2) and 1100K for 30min (CuAl11Mn5) afterwards rapid quenched to 370 K with no further thermic stabilisation. The base alloy of CuAl14.1Mn2.0Ni1.9Fe0.4 had an internal friction measured as logarithmic Decrement (δ) of 0.155 and 0.11 after 2500 h of ageing at RT. The phase transformation is located between 284 K and 352 K, measured by DSC. The alloy of CuAl11.1Mn5.5Zn2.9Ni2.1 had a logarithmic decrement of 0.31 and diminish continuously to 0.12 after 2500 h of ageing at RT. The phase transformation is located between 287 K and 318 K.

title: Determination of caseinomacropeptide in uht milk using near infrared spectroscopy and pls regression

description: ABSTRACT This work´s objective was to develop an UHT milk caseinomacropeptide determination method trough NIR spectroscopy application. Eight UHT milk trademarks are used to produce a mathematical calibration model. The results of NIR analysis suggested that to produce a suitable calibration model, partial least-square regression (PLSR) must be used, with maximum distance in wavelenght space to select spectra, pre - treatment with 2nd derivative and standard normal variant (SNV). Also, suitable near-infrared regions more correlated with CPM aminoacids vibrational movements: 1100-1310; 1400-1430; 1490-1550; 1640-1680; 1780-1970; 2020-2100; and 2310-2350nm. Therefore, NIR spectroscopy can be an alternative to caseinomacropeptide determination of UHT milk, since there was a representative calibration set with a large enough and representative sample of entire population to be predicted in the future.
