Visitantes florais do maracujá-amarelo (Passiflora edulis f. flavicarpa Deg. Passifloraceae) em áreas de cultivo com diferentes proximidades a fragmentos florestais na região Norte Fluminense, RJ

This work aimed to identify the main pollinators and study the floral biology of the yellow passion fruit cultivated in areas within different distances from forest remnants in north Rio de Janeiro state. The yellow passion fruit flowering lasted nine months, from September to March. Anthesis started at 12:00 h and the opening process lasted until 16:30 h. The styles bent down during the anthesis and 72.4% of the flowers had its styles curved. Nectar was produced continuously, reaching 18μl/flower/hour, and the total solute concentration varied between 38 and 42%. Xylocopa frontalis and Xylocopa ordinaria were the most effective yellow passion fruit pollinators because of their visit frequency, intrafloral behavior and body size. These bee species, besides Apis mellifera, were found in all the cultivated areas studied. The highest richness of pollinators was observed in cultivated areas closest to forest remnants. This fact is related to the presence of native bee groups, like Centridini and Euglossina bees (Apidae), which depend on forest areas for nesting and foraging. The forest remnant proximity is also important to provide the nesting and food resources needed by the Xylocopa population during the year.
Fire Ant Response to Management of Native Grass Conservation Buffers

Abstract Native grass conservation buffers established for grassland birds require periodic disturbance, but disturbance of vegetation and soil may increase abundance and activity of imported fire ants (Solenopsis sp.). This is a concern because fire ants are invasive, often respond positively to disturbance and can be a major cause of nest losses in grassland birds. We experimentally tested if fire ant mound density and foraging activity increased after burning and disking in native grass buffers. In 2008, fall disking increased mound density and foraging activity during the first growing season post-disturbance, but burning did not. In 2009, disking had no effect, but effects of disking the previous season persisted into the second growing season. Prescribed fire, which tends to maintain or increase perennial grass cover, may be a better option than disking for managing native grass buffers where fire ant densities are high.
Administração de acetato de melengestrol após inseminação artificial em tempo fixo em vacas Nelore lactantes

The objective of the present study was to assess the effect of administration of Melengestrol Acetate (MGA® Premix) after FTAI, on the conception rate in lactating Nelore breed cows. Experiment I, assessed the effect of administration of 2.28 g MGA/cow/day, from day 13 (D13) until day 18 (D18) after FTAI. The cow were divided into two groups, Group I (n=83, control) that cows were submitted just to FTAI and Group II (n=104, treated) that cows received MGA after FTAI. Experiment II, assessed the effect of administration of 2.28g MGA/cow/day, from day 5 (D5) until day 10 (D10) after FTAI. The cow were divided into two groups, Group I (n=94, control) that cows were submitted just to FTAI and Group II (n=100, treated) that cows received MGA after FTAI. Gestation was diagnosed in both experiments 45 days after FTAI. The conception rates were analyzed by Qui-Square test. In experiment I, The conception rates were 42,16% for control group and 50,0% for treated group (p>0,05). In Experiment II, the conception rate of control group (47,87%) was higher than treated group (28,0%). It was conclude that administration of MGA®Premix from D13 until D18 after FTAI didn’t affect the conception rate. However, when administered from D5 until D10, reduced the conception rate in lactating Nelore breed cows.
Inheritance of drought tolerance in chickpea (Cicer arietinum L.) using joint scaling test.

In order to study the inheritance and genetic analysis of drought tolerance indicators a six generations of F1, F2, BC1 and BC2 of the cross Hashem cultivar x ICCV96029 were studied using generation mean analysis. Genetic variation was found for grain yield, biological yield, No. of pod/plant, No. of seed/plant, earliness and proline content. High heterosis was observed in the F1 hybrid for grain yield, biological yield, harvest index, No. of pod/plant and No. of seed/plant. Genetic analysis indicated dominance in the inheritance of grain yield, biological yield, harvest index, seed weight and No. of seed/plant, while over dominance gene action in the No. of pod/plant, earliness and proline content. Moderate narrow-sense heritability estimates were observed for biological yield, harvest index, seed weight, No. of seed/plant and proline content. Moderate genetic advance for grain yield and proline content indicated that direct and indirect selection through correlated response could be effective. The joint scaling test revealed additivex dominance = [ j ] for grain yield, biological yield and proline content, while duplicate epistasis ( additive x dominance = [ j ] and dominance x dominance = [ l ] ) were shown for No. of pod/plant and No. of seed/pod. Since several important characters are influenced by dominance and non-allelic gene interaction, it is advisable to delay selection to later generation with increased homozygosity
Emerging COTS-Based Computing Platforms in Avionics Need a New Assurance Concept

A new assurance concept for new upcoming COTS-based computing platforms have to be based on a framework that allows to respond to various assurance challenges of different types of COTS hardware technologies. Therefore, we propose to use the generic assurance approach of the Overarching Properties, currently under research, together with assurance case as a tool to get the needed flexibility in the way to argument that the COTS assurance objectives are met. Indeed, to achieve this, it is necessary to develop a concept about COTS assurance in general which is realizable with an assurance case-based Overarching Property approach. This we have already provided in [1]. In this paper we have refined our work to integrate COTS technology specific assurance objectives and explained how their demonstration can be made within this new assurance concept in a coherent way.
Morphological Divergence and the Organization of Trophic Characters Among Lacustrine Populations of the Threespine Stickleback (Gasterosteus aculeatus)

A multivariate solution for dealing with patterns of character covariance, when character genotypic covariances are known, has been applied to the organization of trophic morphology among lacustrine populations of the threespine stickleback (Gasterosteus aculeatus). The quantitative genetics governing eight trophic characters were investigated using representative populations from each of three known trophic ecotypes (open-water, littoral, and intermediate) which occur in the same drainage. Character heritabilities (0.19–0.84) were all significant. Estimates of character genetic correlations (−0.65 < rG < 0.85) were obtained and their standard errors were calculated by bootstrapping. Cluster analyses of the genetic correlation matrices defined two character suites, head shape and gill raker structure. Selection gradients between trophic ecotypes indicated that directional selection had operated most strongly on characters related to food size (upper jaw length and gill raker number). These results support.
The Protective Effect of Hippophae Rhamnoides Carotenoid Extract Against Lipid Peroxidation in Crude Vegetable Oils

Vegetable oils are important elements of the human diet because they contain essential nutritional factors. Due to the manufacturing processes or inadequate conditions of storage, they may also contain lipid oxidation products that are toxic to the body. The purpose of this paper is to test the protective effect of carotenoid-rich extracts obtained from the fruits of Hippophae rhamnoides on crude sunflower, pumpkin and olive oils oxidative processes. In order to evaluate the effect of antioxidant carotenoids, three stages were followed: thermal induction of lipid peroxidation in the presence of AAPH (2,2'-Azobis(2-amidinopropane) dihydrochloride); determination of the level of lipid peroxidation in oxidized oils in the presence and absence of antioxidants, by quantifying the concentration of conjugated dienes and malonyl dialdehyde (MDA); determination of the level of lipid peroxidation by evaluating the profile of the fatty acids and the ratio between the saturated and unsaturated fatty acids (UFA / SFA), using an GC-MS method. In the case of sunflower oil, it was observed that sea buckthorn fruit extract significantly decreased MDA concentration but does not significantly reduce the concentration of conjugated dienes. The protective effect of carotenoids is more evident in the case of oil from pumpkin seeds. In the olive oil, unlike the first two types of oils, the carotenoids extract inhibits both the MDA and the conjugated dienes formation to a lesser extent, statistically insignificant. Overall, the ratio UFA / SFA decreases in crude oxidized oils. In the oils in which carotenoids were added was observed an increase in the UFA / SFA ratio. Carotenoids fraction from sea buckthorn fruits, rich in xanthophyllsâ€™ esters, possess a good antioxidant effect, protecting vegetable oils against peroxidation processes induced in the presence of AAPH
Extracting information from JSON database as simple as extracting in SQL using JSONiq

JSON is a prevalent broadly useful information encoding group, utilized in numerous databases and web administrations. It is simple for a programmer to read and write as worked in a relational database. Like XML, JSON is also a semi-structured database in nature. Extracting information from semi-structured database required special query evaluation and processing engine. Using XQuery static information from XML database can access and retrieve easily through FLWOR construct. To extract structural and semi-structural information from JSON will be done through JSONiq query language and processor. The aim of this paper is finding the similarity between the relational query and JSONiq query and proving that simple queries like join, project, select, group, filter, and aggregate as done in SQL can also be done in JSONiq with JSON database.
Strategies for mixed-grass prairie restoration: herbicide, tilling, and nitrogen manipulation.

Large areas of North American prairie have been planted with grasses introduced from Eurasia. We examined three strategies (herbicide, tilling, and nitrogen manipulation) for enhancing the establishment of seedlings of native species and suppressing the introduced grasses Agropyron cristatum (crested wheat grass) and Bromus inermis (smooth brome). Plots (5 × 15 m) were subjected to one of three levels of tilling (none, intermediate, complete) and four levels of nitrogen (none, intermediate, high, and sawdust added to immobilize nitrogen). Treatments were applied in a factorial design with twelve treatments and ten replicates. Seeds of 41 native species were drilled into the plots in May 1992. Following the failure of seeds to establish in 1992, a subplot (5 × 13 m) within each main plot was sprayed with the herbicide glyphosate in April 1993. The nitrogen treatments were repeated in Spring 1993. In August 1993, the density of native seedlings in sprayed subplots was 20 times that in unsprayed subplots. Within sprayed subplots, native seedling density and the cover of bare ground decreased significantly with increasing nitrogen availability. Plots receiving sawdust had significantly higher mean cover of bare ground and significantly lower concentrations of soil available nitrogen. Native seedling density was significantly higher in plots receiving the highest intensity of tilling. The responses of native seedlings to all these factors point to the importance of neighbor-free establishment sites as a prerequisite for prairie restoration.
Cross-Section Bead Image Prediction in Laser Keyhole Welding of AISI 1020 Steel Using Deep Learning Architectures

A deep learning model was applied for predicting a cross-sectional bead image from laser welding process parameters. The proposed model consists of two successive generators. The first generator produces a weld bead segmentation map from laser intensity and interaction time, which is subsequently translated into an optical microscopic (OM) image by the second generator. Both generators exhibit an encoder–decoder structure based on a convolutional neural network (CNN). In the second generator, a conditional generative adversarial network (cGAN) was additionally employed with multiscale discriminators and residual blocks, considering the size of the OM image. For a training dataset, laser welding experiments with AISI 1020 steel were conducted on a large process window using a 2 KW fiber laser, and a total of 39 process conditions were used for the training. High-resolution OM images were successfully generated, and the predicted bead shapes were reasonably accurate (R-Squared: 89.0% for penetration depth, 93.6% for weld bead area).
PI01-07 2275

Results: It was determined that there was a close correlation between mercury doses from thimerosal-containing childhood vaccines and the prevalence of autism from the late 1980s through the mid-1990s. In contrast, there was a potential correlation between the number of primary pediatric measles-containing vaccines administered and the prevalence of autism during the 1980s. In addition, it was found that there were statistically significant odds ratios for the development of autism following increasing doses of mercury from thimerosal-containing vaccines (birth cohorts: 1985 and 1990–1995) in comparison to a baseline measurement (birth cohort: 1984). The contribution of thimerosal from childhood vaccines (>50% effect) was greater than MMR vaccine on the prevalence of autism observed in this study.
A Novel Interpolation-SVT Approach for Recovering Missing Low-Rank Air Quality Data

With increasing public demands for timely and accurate air pollution reporting, more air quality monitoring stations have been deployed by the governments in urban metropolises to increase the coverage of urban air pollution monitoring. However, due to systematic or accidental failures, some air pollution measurements obtained from these stations are found to have missing values, which will adversely affect the accuracy of any follow-up air pollution analyses and the quality of environmental decision-makings. In this study, the mathematical property of air quality measurements is investigated to recover the missing air pollution values. A new algorithm, which matches meteorology data with air pollution data from different locations, to reconstruct the data matrix and recover missing entries, is proposed. Next, a Low Rank Matrix Completion problem is used to reconstruct the missing values, by transforming the data recovery problem to a sub-gradient primal-dual problem, based on the duality theory, with Singular Value Thresholding (SVT) employed to develop sub-optimal solutions. Next, an Interpolation-SVT (ISVT) approach is adopted to handle the sparsity of observed measurements. Comprehensive case studies are conducted to evaluate the performance of the proposed methods. The simulation results have demonstrated that the proposed SVT and ISVT methods can effectively recover the missing air pollution data and outperform existing interpolation methods and data imputation techniques. The proposed study can improve air pollution estimation and prediction whenever the low-rank data types that are used as proxies for air pollution estimation contain a lot of missing values and require data recovery.

Light microscopy and scanning electron microscopy investigations of adult morphology show obvious differences from previously recorded Chthamalus species, and that this species belongs to the ‘C. challengeri group’ of Chthamalidae.
New Zealand pest management: current and future challenges

New Zealand is under increasing pressure from terrestrial and aquatic pests, weeds and diseases that threaten the country's ecosystems and economy. Ongoing improvement in existing pest management methodologies and novel approaches are required in response to public concerns about animal welfare, increasingly stringent trade requirements, abolition of groups of pesticides and resistance to existing pesticides as well as, possibly, biological control agents. Surveillance and pest monitoring are needed to increase the chances of early interception of invasive species or to confirm their eradication. Core capabilities in taxonomy, genomics, phenology, ecology, pest impacts, development of novel control tools and social science are required and must be maintained nationally. Given New Zealand's unique environment, the ecology of invasive pests cannot be presumed to be the same as that in their native ranges, yet currently many pests in New Zealand are managed with poor understanding of their bionomics and impacts. Failure to address these areas will have serious adverse impacts on New Zealand.
Sexual Lability in Teleosts: Developmental Factors

Among vertebrates there is wide variation in the degree to which sexual differentiation is developmentally buffered, or canalized. In birds, and particularly in mammals, gonadogenesis occurs early in development and without a significant contribution from the environment. In contrast, sexual development in teleosts is protracted and plastic. Here I consider this lability in the context of the developmental processes underlying sex differentiation in teleosts, and contrast these processes with those in other vertebrate taxa. One fundamental difference in teleost sexual differentiation from that of letrapods may be in the developmental polarity of the brain-pituitary-gonadal axis. In mammals the gonads differentiate early and affect, through the release of steroid hormones, the sexual differentiation of the brain. It is proposed here that in teleosts the brain is the initial site of sexual differentiation, and that the pattern of differentiation in the brain determines the fate of the gonads.
Interstitial lung disease and microscopic polyangiitis in chilean patients

Objective: To describe the clinical and serological patients characteristics with Microscopic Polyangiitis (MPA) and Interstitial lung disease (ILD). Methods: Of all the patients with AAV diagnosed between 2007-2017 at the Hospital Clinico Universidad de Chile, those with MPA and ILD were selected and studied retrospectively. Results: All patients were Hispanic; median age at diagnosis 65 years (32-84). 59% were female. All were positive for p-ANCA, 16 patients for MPO. Most common manifestations were constitutional symptoms, weight loss and fever. CT-Scans patterns were Usual Interstitial Pneumonia (UIP) in 10 patients, Nonspecific Interstitial Pneumonia (NSIP) in 6 and fibrosis not UIP or NSIP pattern in 1. In 6 cases, ILD was diagnosed 0.5-14 years before MPA and concomitantly in 11. Conclusions: Although infrequent, Microscopic Polyangiitis should be suspected in patients with ILD particularly if extra-pulmonary manifestations that rise the possibility of a systemic illness are present, regardless of the time elapsed between the latter and the diagnosis of this type of lung involvement.

The relative importance of latitude matching and propagule pressure in the colonization success of an invasive forb

Factors that influence the early stages of invasion can be critical to invasion success, yet are seldom studied. In particular, broad pre-adaptation to recipient climate may importantly influence early colonization success, yet few studies have explicitly examined this. I performed an experiment to determine how similarity between seed source and transplant site latitude, as a general indicator of pre-adaptation to climate, interacts with propagule pressure (100, 200 and 400 seeds/pot) to influence early colonization success of the widespread North American weed, St. John's wort Hypericum perforatum. Seeds originating from seven native European source populations were sown in pots buried in the ground in a field in western Montana. Seed source populations were either similar or divergent in latitude to the recipient transplant site. Across seed density treatments, the match between seed source and recipient latitude did not affect the proportion of pots colonized or the number of individual colonists per pot. In contrast, propagule pressure had a significant and positive effect on colonization. These results suggest that propagules from many climatically divergent source populations can be viable invaders.
(2019). Factors associated with discontinuation of antidepressant treatment after a single prescription among patients aged 55 or over: evidence from English primary care. Social Psychiatry and Psychiatric Epidemiology,

Purpose Antidepressants are frequently prescribed to older people with depression but little is known on predictors of discontinuation in this population. We therefore investigated factors associated with early discontinuation of antidepressants in older adults with new diagnoses or symptoms of depression in English primary care. Methods Data from a nationally representative cohort of patients aged 55 and over were used to evaluate the association between discontinuation of antidepressant medication after a single prescription and potential explanatory variables, including socio-demographic factors, polypharmacy and age-related problems such as dementia. Results Overall, during the study period we observed 34,715 new courses of antidepressant treatment initiated after recorded symptoms or diagnoses of depression. Antidepressant discontinuation after a single prescription was more common in people with depressive symptoms (32%) than in those with diagnosed depression (21.6%). In those diagnosed with depression and in women with depressive symptoms we found that, after adjusting for confounders, the odds of early discontinuation significantly increased after age 65 with a peak at around age 80 and then either levelled or reduced thereafter. Early discontinuation was also significantly less common in people with dementia and in those with diagnosed depression living in more rural areas.
A 108 GHz Up-Conversion Mixer in 22 nm FDSOI

This paper presents a 108 GHz up-conversion micromixer in a 22 nm FDSOI technology. It has a conversion gain of −4.8 dB with a 3-dB bandwidth of 24 GHz, drawing 6 mA from a 1.8 V supply. The differential output of the micromixer is measured single ended on-wafer through a wideband miniaturized passive balun. To supply sufficient LO drive power, a three-stage amplifier is included on chip. The first two stages of this driver amplifier are measured in a separate breakout, which is also presented. It shows 12.5 dB small signal gain and 8.4 dBm saturated output power.
