title: Characterization of tolerance to citrus leafminer of Citrus and related genera

description: ABSTRACT The aim of this study was to identify resistance of tolerance type in Citrus and Poncirus genotypes towards the citrus leafminer (CLM), Phyllocnistis citrella. The quantitative variables leaf and shoot lengths, leaf width, number of larvae and new shoots, and fresh and dry shoots weights, and qualitative variables associated with foliar damage were evaluated in six Citrus-related genotypes infested with CLM. In preliminary trials with lime Rough lemon (C. jambhiri), the variables that best discriminated the infestation effect of CLM were established as the numbers of larvae and new shoots per plant together with the percentages of partially rolled leaves (PRL), rolled leaves (RL) and total damage (TD = RL + PRL). In subsequent tests with all six genotypes, the variables new shoots per plant, percentage of attacked but not rolled leaves (ANRL), RL and TD were found to be significant. Trifoliata Limeira (P. trifoliata) and hybrid C × R4 (C. sunki × P. trifoliata) presented the lowest percentages of RL and TD and the highest values of ANRL. A cluster analysis was performed considering all the variables analyzed and the most tolerant genotypes for CLM, namely hybridsC × R4, C × R315 (C. sunki × P. trifoliata), M × P222 [C. sinensis × Tangor Murcott (C. reticulata × C. sinensis)] and Trifoliata Limeira (P. trifoliata) were grouped apart from the less tolerant genotypes Sunki mandarin (C. sunki) and lime Rough lemon. In conclusion, genotypes Trifoliata Limeira and its hybrid C × R4 are the most tolerant to CLM.

title: Occurrence of anti-Leishmania spp antibodies in felines in an endemic area of the State of São Paulo

description: ABSTRACT Visceral leishmaniasis (VL) is a zoonosis with a great impact on public health. Infection in cats has been reported in countries where the disease is endemic. Its role as reservoir is not satisfactorily elucidated, although transmission of the parasite from an infected feline to vector has been reported by xenodiagnosis. The objective of this study was to evaluate the presence of anti-Leishmania spp antibodies in feline animals in an area endemic to LV (Bauru-SP), using the serological tests of Indirect Immunofluorescence Reaction (IFR) and ELISA and variables: gender, age, race and form of creation. Samples of 276 felines were tested, of which 82 were ELISA reagents (29,71%), 17 by IFR (6,15%) and 10 in both tests (3,6%). There was a significant statistical association for the variable form of breeding, where 100% of the wandering animals were seropositive to at least one of the tests (P &lt;0,005). Such association was not found for the other variables analyzed (P &gt;0,05). There was no concordance between the results of the tests, since the ELISA method is more sensitive than the RIFI method.

title: Sampling of cashew nuts as an aid to research for the genetic improvement of cashew tree

description: Abstract: The objective of this work was to estimate sample sizes of cashew (Anacardium occidentale) nuts as an aid to the genetic improvement of cashew tree. Nuts were separated by size: nuts &lt; 17 mm were classified as size 1 (S1); 17 mm ≤ nuts &lt; 19 mm, size 2 (S2); 19 mm ≤ nuts &lt; 23 mm, size 3 (S3); 23 mm ≤ nuts &lt; 25 mm, size 4 (S4); and nuts ≥ 25 mm, size 5 (S5). Sizing the sample for each stratum depends on the variance of nut size and on the error level B allowed for either the estimates or the desired precision in the results. The sample size will be larger the greater the variance of the stratum, the lower the error level allowed for the estimates, or the greater the precision desired in the results. For an error B = 0.2 g, the sample sizes of the S5, S4, and S3 strata were n5 = 42 nuts, n4 = 30 nuts, and n3 = 19 nuts, respectively. In the S5 and S4 strata, with better nut classifications, the average weight was 12.71 and 9.76 g, respectively. The Sm stratum - formed by the mixture of nuts of several sizes - should not be used as a parameter in this context due to its great variability, which is far larger than that of the other strata. Stratified sampling composed of six strata (S1, S2, ..., S5, Sm) is effective for estimating different sizes of nut samples.

title: Prevalence of multiple sclerosis in Goiânia, Goiás, Brazil

description: ABSTRACT Multiple sclerosis (MS) prevalence, in some cities in Brazil, was estimated and was found to range from 0.75 to 30.7/100,000. The reasons for such a large variation in rates of prevalence are not clear, but environment and genetics help to explain this phenomenon. Methods: A cross-sectional study using three sources of case ascertainment to estimate the prevalence of MS in the city of Goiânia in December, 2015. Results: A total of 318 MS patients was found after removing overlapping sources. The prevalence of MS was 22.4/100,000 population. Conclusion: Our study was the first in Goiás and the third in the midwest region, and we found a great increase in the prevalence of MS in the region. It is necessary to perform other studies using the same methodology for a more accurate evaluation of the true prevalence of MS in Brazil.

title: Effect of construction and demolition waste (CDW) addition on the hydromechanical properties of a sandy-clayey soil

description: ABSTRACT As the production of solid waste resulting from human actions, such as Construction and Demolition Waste (CDW), has continually increased, proper disposal of these materials has become critically important, because when improperly disposed, they degrade the environment and contribute to the proliferation of disease vectors. The construction industry has also faced difficulties in searching for areas with soils suitable for use in engineering projects, leading to efforts to improve soils having unsatisfactory characteristics. This study aims to analyze the influence of recycled CDW aggregates on the hydromechanical properties of clay-sand soil at different substitution levels (10, 20, and 30%). To achieve this, the materials used were submitted to a variety of laboratory tests: physical characterization, normal Proctor energy compaction, microstructural characterization, direct shear, and permeability of the compacted samples under optimum compaction conditions. The results show that for the soil used, the addition of recycled CDW aggregate reduces its fine fractions and plasticity, interferes minimally in the real specific weight, decreases the optimal humidity by up to 2%, with a low variation of the apparent dry specific weight, keeps within the range of values for the resistance parameters, and increase in the hydraulic coefficient of the soil by more than 13 times. The differences in hydraulic behavior can be explained by observed changes in the microstructure of the samples.

title: Mechanical behavior of clay soil stabilizedwith glass residue powdered in high-energy and ball mills

description: ABSTRACT The capital of the Amazonas State presents difficulties in the construction of pavements due to the superficial predominance of clay in its geotechnical profile. This material is unsuitable for the construction of sublayers of these urban structures. In the present study, the mechanical behavior of the Manaus-AM typical clay soil was evaluated in its natural condition and when mixed with 5% of powdered glass waste processed in two types of mills (balls and high energy) in order to improve their geotechnical properties. The natural material and its compositions was characterized in relation to their physical properties (liquidity limit, plasticity limit, grain size and compaction) and mineralogical properties, as well as the natural soil mineralogy. According to the direct shear test and the Coulomb rupture criterion, the cohesion and the internal friction angle of the clay soil were determined, as well of the soil compositions with 5% of powdered glass processed in ball mill and 5% of powdered glass processed in high-energy mill. The results showed that there was a significant improvement in the regional soil properties when glass residue is added, both physically and mechanically, with emphasis on the participation of the powdered material processed in the high-energy mill. Therefore, the powdered glass has the potential to be used as granulometric stabilizer in roadways construction, which is an environmental alternative for the disposal of such materials.

title: Evaluation of some reproductive traits of Pelibuey ewes under humid tropical conditions of Mexico

description: ABSTRACT We evaluated the effect of some environmental factors on age at first lambing (AFL) and lambing to conception interval (LCI) of Pelibuey ewes under the humid tropical conditions of Mexico. Ewes grazed on Tanzania (Panicum maximum), Bermuda (Cynodon dactylon), and Brachiaria grass (Brachiaria humidicola) and received hay in the corral in the months of grass scarcity. Reproduction was continuous during the year. Data of 839 lambings from 334 ewes registered from 2009 to 2017 were analyzed using survival analysis procedures. The statistical model for AFL included the effects of year, season, and litter size at lambing, whereas that for LCI included year and season plus parity number of ewe and litter size at weaning. The overall means ± SD for AFL and LCI were 551.6±144.8 and 145.4±113.1 days, and their medians were 510 and 98 days, respectively. Only year of lambing had a significant effect on AFL, whereas LCI was affected by year, parity number, and litter size at lambing (P&lt;0.05). Both AFL and LCI means did not show any trend with advancing years. The largest AFL and LCI means and medians corresponded to the first-parity ewes. In addition, single birth ewes had the longest LCI means and median. Therefore, year of lambing affects AFL, whereas year of lambing, parity number, and litter size at weaning affect LCI of Pelibuey ewes, indicating that these factors should be considered in the development of sound strategies to improve sheep production.

title: Ropivacaine sole or associated to methadone or morphine, by epidural route, in bitches undergoing ovariohysterectomy

description: ABSTRACT The aim of this study was to evaluate the physiological, sedative and analgesic effects of epidural administration of ropivacaine sole or associated to morphine or methadone. Twenty-four bitches were submitted to ovariohysterectomy and received acepromazine and after, propofol and isoflurane (FiO 2 = 1.0) for anesthesia induction and maintenance, respectively. Based on established epidural protocol (L7-S1), three groups were formed: GR (ropivacaine - 2.0mg/kg); GRMETA (ropivacaine - 2.0mg/kg and methadone - 0.3mg/kg) and GRMORF (ropivacaine - 2.0mg/kg and morphine - 0.1mg/kg). Intraoperative physiological parameters and degrees of postoperative sedation and analgesia were recorded. In the GR, the means of arterial pressures, 30 minutes after epidural anesthesia, were higher compared with GRMETA (systolic and mean) and, at the end of the clinical procedure, compared to GRMORF (systolic, diastolic and mean). Differences between groups were not observed for postoperative analgesia and degree of sedation. Epidural administration of ropivacaine is safe and effective and provides good analgesia regardless of its association with morphine or methadone.

title: Effects of extrinsic feedback on the motor learning after stroke

description: Abstract Aim: This study aims to investigate the effects of the type of extrinsic feedback provided equally in terms of timing and frequency of delivery on the motor learning after stroke. Methods: Twenty post-stroke individuals were distributed randomly into two groups according to the type of feedback provided: knowledge of performance experimental group (KPEG) and knowledge of results experimental group (KREG). Additionally, a control group (CG) was consisted of 20 healthy individuals age- and feedback-matched with the experimental groups. The task was a pointing skill performed in a virtual reality system. The acquisition phase consisted of 3 days/ 75 trials per day. Two retention tests (ret1 and ret2) were run after four days from the acquisition phase. Dependent variable measures were defined by motor performance and movement pattern. Results: The statistical analysis showed interaction effect F(3,108 = 49.13, p = 0.01) among KPEG and KREG. Based on the motor performance parameters (score) the KPEG improved performance significantly from pre to post (p = 0.001), and maintain it from pre to ret1 (p = 0.002), and from the pre to ret2 (p = 0.001). However, the KREG only showed a difference in motor performance from the pre to post (p = 0.003). Compared to the KREG, the KPEG showed improvement on the movement pattern based on the smoothness (p = 0.004), which suggests that the KPEG performed more corrections of movements in relation to the CG and KREG groups. Conclusion: These findings suggest that KP allowed better motor learning in individuals after stroke.

title: Changing the characteristics of the nitrided layer using three different plasma configurations

description: ABSTRACT Direct current (DC) plasma nitriding offers some disadvantages, especially in parts with complex geometries, where the presence of edges is significant, such as gears, molds, and needle punched parts are strongly affected by this effect, leading to irregular formation of nitrided layers and high variation in surface hardness. To solve these problems two techniques were developed as alternatives, namely: pulsed plasma nitriding and cathodic cage nitriding. In this work, these three nitriding techniques were compared using AISI 1045 steel as substrate. Steel discs were nitrided with the purpose of evaluating the influence of these different plasma configurations on the characteristics of the nitrided layer. The treatments in the three techniques were carried out at the same pressure, temperature, time and gas atmosphere. The samples were characterized for the microstructure, microhardness and crystalline phases present. X-ray diffraction with grazing incidence was used to verify the order of the nitrites formed and to estimate the thickness of the single-phase layers. Differences between the configurations with respect to the occurrence of restriction rings, total thickness (xε +xγ') and relative (xε/xγ') compound layers were observed.

title: Experimental study of dehydration processes of raspberries (Rubus Idaeus ) with microwave and solar drying

description: Abstract The aim of the present study was to evaluate the effect of solar and microwave drying on raspberries (Rubus Idaeus) cv. Heritage. The efficiency of drying was evaluated in terms of weight reduction in function of the time. The quality properties evaluated were color, texture, antioxidant capacity and total polyphenols content. The results showed that solar drying and microwave drying allowed a good preservation of surface color in the final product. However, the solar drying achieved a desirable texture in dried raspberries compared to microwave drying. Neither solar drying nor microwave drying allowed a high retention of the antioxidant capacity. Nevertheless, both processes allow obtaining final stable fruits (low water activity) at any time of the year.
