title: LAPAROSCOPIC TECHNIQUE VERSUS OPEN TECHNIQUE IN SWINES ADRENALECTOMY

description: Among the main benefits of laparoscopic adrenalectomy (LA) compared to open adrenalectomy (OA) the rapid recovery of patients with decreased length of stay in hospital can be highlighted. The objective of this study was to compare the open adrenalectomy with laparoscopic adrenalectomy in swine. Thirty-two swine were operated. The animals had been divided into four groups (n = 8), one group was submitted to OA and the other to LA, together with its respective control group. Parameters were evaluated regarding operative time, body temperature, hematocrit, postoperative and intraoperative complications and time to deambulation. There was no meaningful difference between operative and deambulation times, even though the latter having been higher in the group submitted to OA. The most frequent intercurrences were in bowel, damage to adrenal vessels and renal hematoma. There were no significant blood losses, and observed hypothermia did not have any clinical impact. Laparoscopy in swine experimental adrenalectomy is a reliable technique that can serve as a reference for the surgical treatment of patients with adrenal diseases with surgical indications in other animal species.

title: The Perception of Voice Quality by Brazilian Bilinguals

description: Abstract Research has shown that bilingual speakers can alter their voice when speaking a foreign language in comparison to their voice in L1. It remains to be seen whether listeners perceive these differences. Thus, the present study explores the perception of voice quality by bilingual Brazilian listeners in speech in Brazilian Portuguese (BP) and English (EN) produced by bilingual Brazilian speakers. To achieve this objective, a voice discrimination task with semantically similar speech samples from the same speaker was carried out. Listeners judged if voices in LE were the same or different than voices in L1, describing their characteristics in case they were different. Results point to certain variability in judgements, but also reveal that listeners are capable of identifying differences in pitch and intensity between languages, as well as conferring characteristics of personality and emotion to the speech samples in both languages.

title: Effect of LZSA glass-ceramic addition on the erosive wear of pressureless sintered alumina

description: Abstract This study aims to evaluate the influence of the 11.6Li2O-16.8ZrO2-68.2SiO2-3.4Al2O3 (mol%) glass-ceramic addition (LZSA, 7 to 21 vol%) on the erosive wear of alumina in comparison to values of pure alumina obtained from the literature. Thus, composites were prepared from three commercial alumina of different initial particle sizes. Specimens were obtained by uniaxial pressing. Sintering temperatures and holding times were found to be different for each composite. The erosive wear test was carried out in an apparatus based on the standard ASTM G 76-4. The volumetric erosive wear (T vol) was correlated to the initial mean particle size of alumina, LZSA glass-ceramic content, average grain size of sintered alumina (AGS), porosity (P), elastic modulus, fracture toughness, natural defect size, and fracture energy based on a correlation matrix of statistical analyses. The experimental data of Tvol fit very well with P and AGS, individually, in a 3rd degree equation, except for composite AF21. Composite AF21, i.e. 21 vol% LZSA added to 0.5 µm mean particle size alumina (AF, fine alumina) and sintered at 1470 oC for 3 h, showed interesting results of T vol(2.05 × 10-8 m3·kg-1) related to the other investigated compositions, which varied from 1.90-4.37 × 10-8 m3·kg-1, and those existing in literature (0.55 × 10-8 to 10.78 × 10-8 m³·kg-1), mostly when considering the lower sintering temperature (1470 against 1600 oC). Thus, although the AC7 composite had shown the lowest Tvol value (1.90 × 10-8 at 1600 oC/7 h), the composite AF21 can be considered as the best result because of its lower sintering temperature and holding time (2.05 × 10-8 at 1470 oC/4 h). The formation of a viscous liquid phase, which crystallizes during the controlled cooling in the microstructure of the LZSA/alumina-based composites, improves the erosive wear of the alumina.

title: The regional distribution of the provision of training in the Multi-professional Residency in Health modality

description: ABSTRACT The Multi-professional Health Residency (RMS) programs provoke reflections on daily work, the relationships and the work process, and have the potential to modify not only the perspective of the graduated individual, but also the spaces in which they develop, strengthening the continuous process of permanent education in health. Studies that investigate how the multi-professional residency programs supported by the Ministry of Health (MS) have been structured are timely and relevant, given the contributions of these initiatives to the Unified Health System (SUS). This work analyzes the RMS, with the goal of identifying how the programs funded by the MS are distributed regionally across the country. An exploratory documentary research was carried out using edicts and ordinances published by the MS in the period from 2009 to 2015. The majority of the approved programs are concentrated in the Southeast region, mainly in São Paulo, followed by the Northeast and South regions. The North and Midwest regions were the least representative in the total amount of the selected programs. On the other hand, the Northeast region presented an increment of programs induced by the priority given in the published official notices. There was an attempt to organize the distribution and a tendency to increase of programs submitted and approved.

title: Growth and gas exchange of cowpea bean genotypes under strategies of cultivation

description: Abstract The cowpea bean has great economic, nutritive and social importance. In the Northeast, especially in semi-arid regions, cowpea production is limited due to a lack of water, making it necessary to identify tolerant genotypes and cultivation technologies. This study therefore aimed to analyze the dry matter yield and the gas exchange between cowpea genotypes cultivated using different water conservation techniques. The experiment was conducted in the field in the city of Pombal, Paraíba, in order to study four treatments that use different water retention techniques (ridge, groove, basin and conventional system) applying six genotypes of cowpea bean (1. Costela de Vaca, 2. BRS Itaim, 3. BRS Guariba, 4. BR-17 Gurgueia, 5. BRS Potengi e 6. BRS Arace) sowing with 0.5 m x 0.5 m spacing between plants, using the randomized blocks design with four replications. Dry matter yield and gas exchange data were subjected to ANOVA, F test, followed by mean comparison tests, Tukey test. The groove and ridge cultivation techniques had better results than the basin and conventional techniques. The BRS- Potengi, BRS - Aracé e BRS - Guariba genotypes had better growth and gas exchange potential.

title: Field parametric geostatistics - An alternative to tackle gold grade estimations

description: Abstract High anomalous grades are very common in gold deposits, whose presence requires careful treatment to prevent overestimation of metal content. Mineral resource analysts have worked on the estimation of several gold deposits, and none of the classical methods were able to avoid manual interventions, such as cutting high grades for local estimation or using more information beyond the data for the variogram inference. The Field Parametric Geostatistics (FPG) is presented as an alternative for the application of linear kriging methods to estimate highly skewed distributions, proposing a mathematical model which incorporates the grades and its representativeness into a new variable, reducing the influence of high grades without empirical manual interventions. In this article, the mathematical formulation of the FPG theory is presented, as well as its application in datasets with outliers and high skewed distributions: the Walker Lake dataset and the Amapari gold deposit. The results are compared to results obtained by the application of standard techniques, demonstrating that FPG is a feasible alternative to estimate local grades and local reserves for highly skewed variables.

title: Evaluation of grinding circuits for iron ore

description: Abstract Grinding has become one of the most important unitary operations for producing pellet feed for direct reduction from low-grade ores and small liberation size, such as compact itabirites. The aim of this study was to evaluate and compare two grinding circuits in an industrial iron ore plant, by evaluating the current operation through sampling, industrial data analysis and mass balancing. The flows analyzed were the grinding circuit, flotation throughput and desliming hydrocyclone overflow. In total, two grinding circuits were tested. One circuit had two mills installed in series, with the first mill operating in an open circuit and the second mill, in a reverse closed circuit. The second grinding circuit involved two mills operating in parallel, both in direct closed circuits. The results indicated that the parallel circuit produced 20% less slime than the series circuit, with an additional 4.3% throughput in the flotation feed. No circuit produced particles (&gt; 0.15mm). The parallel circuit spent less 8.3% of energy by not using one of the hydrocyclone batteries.

title: Cold shortening decreases the tenderization of Biceps femoris muscle from lambs

description: SUMMARY This study evaluates the effects of Normal Shortening (NS) and Cold Shortening (CS) in sarcomere length, Warner-Bratzler shear force (WBS) and tenderization process examined by Myofibrillar Fragmentation Index (MFI). The Biceps femoris muscle from ten Dorper x Santa Inês lambs was randomly assigned to 1) NS = cooling of the muscle in the carcass for 24 hours in a cold room at 4°C; or 2) CS = rapid cooling, in ice bath, of the muscle removed from the carcass immediately after slaughter. Sarcomere Length (SL) was determined in the collected samples 24 hours after slaughter and WBS and MFI in the aging periods (1 or 10 days post-mortem). The WBS value of the meat for 1 and 10 days were greater (P&lt;0.05) for CS (4.90 ± 0.42 and 3.73 ± 0.42 kgf, respectively) than NS (4.07 ± 0.36 and 2.98 ± 0.38 kgf, respectively). There were negative correlations between WBS and SL (r= −0.59 and r=−0.69, P&lt; 0.05) at 1 and 10 postmortem, respectively. Furthermore, there were positive correlations for MFI and SL (r= 0.46 and r=0.48, P&lt; 0.05) at days 1 and 10, respectively. These results point to a negative impact of sarcomere cold shortening in the sheep meat tenderization process in the hindlimb muscle.

title: SOIL CHEMICAL ATTRIBUTES AND CORN PRODUCTIVITY GROWN ON LEGUME STUBBLE IN AGROFORESTRY SYSTEMS

description: ABSTRACT Leguminous species can improve nutrient cycling and chemical quality of Oxisols, resulting in higher productivity of intercropped crops. Thus, this research aimed to evaluate the decomposition rate and nutrient accumulation in legume stubble, as well as its contribution to soil chemical attributes, the growth of baru trees (Dipteryx alata Vogel), and yield of intercropped maize in an agroforestry system. The experiment was developed during the crop years of 2010-2011 and 2011-2012, in Goiás State, Brazil. The experimental design was a randomized block with five replicates. Leguminous species consisted of sunn hemp (Crotalaria juncea), jack bean (Canavalia ensiformis), pigeon pea (Cajanus cajan), Stylosanthes (Stylosanthes macrocephala - 20% and Stylosanthes capitata - 80%), and spontaneous vegetation (control treatment). The decomposition rates of legume and spontaneous vegetation residues remained unchanged in the agroforestry system. Sunn hemp, jack bean, and Stylosanthes plants are advantageous options for total accumulation of nutrients. However, sunn hemp grown as straw cover for next crop seasons increases the available phosphorus levels in the soil and productivity of maize cobs. With this coverage, maize productivity values were up to 24% higher than were those with maize growing on spontaneous vegetation, besides having no effect on the growth of baru trees.
