title: Morphological characterization of insect galls and new records of associated invertebrates in a Cerrado area in Bahia State, Brazil

description: Abstract In this study, we report the first records and morphological characterization of galls in a Cerrado area in western Bahia, Brazil. The data were collected monthly over two hours between March and September 2015. Fifteen gall morphotypes were found in twelve plant species distributed among seven families. The plant family with the greatest richness of galls was Fabaceae (n = 8). The following gall morphologies were found: globoid, lenticular, marginal leaf roll, conical, cylindrical, fusiform, spherical and pocket shaped. Cecidomyiidae induced globoid, lenticular, conical, fusiform, spherical and cylindrical morphotypes. In addition, species of microhymenoptera belonging to the Eulophidae, Eurytomidae and Encyrtidae families were found. Marginal leaf roll and pocket-shaped galls induced by Thysanoptera were also verified. Springtails were also identified as a successor. Undescribed species of Schizomyia and Lopesia were recorded in B. cupulata and Andira humilis, respectively.

title: Diffuse pollution of storm water runoff from an urban catchment

description: ABSTRACT The aim of this study was to evaluate the first wash load of an urban catchment located in the city of Natal, Rio Grande do Norte, Brazil, by quantifying pollution loads contained in surface run-offs from nine rainfall events, monitored throughout the year 2013. The variables analyzed were: total solids, total suspended solids, chemical oxygen demand, total phosphorus and oil and grease content. We conducted the evaluation of precipitation/runoff events through progressive sampling of runoff, monitored by autosampler (ISCO 6712), and located at the outlet of the drainage basin. The first 24 minutes of runoff were analyzed, with samples collected every minute throughout the event. The variation of the pollutants concentration associated with the temporal run-offs variation during precipitation was analyzed to verify the occurrence of the first flush phenomenon. The monitored period was characterized by having a low number of drought days between events. The occurrence of the first flush was observed in five of the monitored events. Thus, it became clear that for the studied basin, the concept of first flush could be applied in rainwater management strategies for the implementation of best management practices, which have been widely disseminated regarding urban drainage.

title: Prospective evaluation of vesicourethral anastomosis outcomes in robotic radical prostatectomy during early experience in a university hospital

description: ABSTRACT Purpose: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. Materials and Methods: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. Results: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. Conclusion: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.

title: Hepatocyte-specific contrast agent-enhanced magnetic resonance cholangiography: perioperative evaluation of the biliary tree

description: Abstract A large number of gadolinium chelates have recently been tested in clinical trials. Some of those have already been approved for clinical use in the United States and Europe. Thus, new diagnostic perspectives have been incorporated into magnetic resonance imaging studies. Among such gadolinium chelates are hepatobiliary-specific contrast agents (HSCAs), which, due to their property of being selectively taken up by hepatocytes and excreted by the biliary ducts, have been widely used for the detection and characterization of focal hepatic lesions. In comparison with conventional magnetic resonance cholangiography (MRC), HSCA-enhanced MRC provides additional information, with higher spatial resolution and better anatomic evaluation of a non-dilated biliary tree. A thorough anatomic assessment of the biliary tree is crucial in various hepatic surgical procedures, such as complex resection in patients with colorectal cancer and living-donor liver transplantation. However, the use of HSCA-enhanced MRC is still limited, because of a lack of data in the literature and the poor familiarity of radiologists regarding its main indications. This pictorial essay aims to demonstrate the use of HSCA-enhanced MRC, with particular emphasis on anatomical analysis of the biliary tree, clinical applications, and the most important imaging findings.

title: Searching for Psychological Predictors of Suicidal Ideation in University Students

description: ABSTRACT The present study aims to identify psychological predictors of suicidal ideation in university students. We collected a sample of 366 participants, representing a population of 7102 students from a university in northern Portugal (95% CI). Both in the whole sample and in the intra-gender analysis, students with suicidal ideation revealed higher levels of depressive symptoms, loneliness, social anxiety and fears of abandonment, and lower levels of comfort with intimacy and trust in others. Loneliness and depression are significant predictors of suicidal ideation, with an odds ratio of 1.095 and 1.108, respectively. The results were consistent with those found in the literature, and call for more research and implementation of intervention protocols in university populations.

title: Effectiveness of a Brief Intervention based on Motivational Interviewing in Colombian Adolescents

description: ABSTRACT Prevention science has identified evidence-based strategies for reducing alcohol and other drug use among adolescents, such as Brief Interventions (BI) and Motivational Interviewing (MI). However, there is little evidence about the effectiveness of these practices in Colombia. This study aimed to analyze the effectiveness of the preventive program Brief Intervention based on Motivational Interviewing (BIMI) in reducing alcohol use in adolescents. The program was administered to 3,159 secondary students through a within-subjects design. The results showed that BIMI is a preventive strategy that diminishes the frequency and quantity of alcohol consumption. The study examines how the elapsed time between sessions influences the results. Implications for prevention and evaluation methodologies are discussed.

title: Variation of the modulus of elasticity of a collapsible soil of Petrolina-PE with and without flood

description: ABSTRACT Collapsible soils are unsaturated soils that undergo radical rearrangement of particles and great reduction of volume when wetting, with or without additional load application. These soils present serious problems for Geotechnical Engineering when there is a change of water content, causing additional deformations to the soils. The analysis of their behavior becomes an essential step for the success of an engineering project. Single and double edometric tests with controlled suction and the use of the Expanso-colapsometer were widely used to analyze the volume variation of the collapsible soils due to the change of water content , since they allow to evaluate the behavior of the collapsible soils in a way that simulate the conditions to which the soil will be submitted. The objective of this paper is to evaluate the elastic modulus in field of a collapsible soil of a residential complex in Petrolina-PE, with and without previous wetting. It was used in the field the Light Weight Deflectometer - LWD that is modern equipment that application load dynamic in a plate to the ground and allows measuring the deflections and quantifies the modulus of elasticity. The physical characterization of the soil was performed in the laboratory. The result showed a predominantly sandy soil with a modulus of elasticity ranging from 46.3 to 79.2 MPa and the wetting causes a reduction of 88%. In addition, it was found that the increase of moisture associated with the application of the dynamic load causes a reduction of its stiffness, occurring a decrease of the modulus of elasticity and, consequently, an increase of the deflection. From the results of the LWD, a criterion of identification of collapsible soil was established through the KLWD coefficient, attesting that Petrolina’s soil presents the following susceptibility to collapse: high for KLWD&gt; 4.2, low for KLWD &lt;2.8 and medium For KLWD between 2.8 and 4.2.

title: Storage of methane at low pressure in activated carbon under different temperature and flow rate of charge conditions

description: ABSTRACT Methane storage in adsorbed form in activated carbon (ANG - Adsorbed Natural Gas) has attracted attention in recent years by applying reduced pressures when compared to CNG (Compressed Natural Gas) technology and reduced temperatures, and also for representing an important alternative use of biomethane derived from biogas purification in vehicular and stationary systems. This study aimed an evaluation of methane storage in activated carbon under different conditions of temperature and flow rate of charge in a prototype system. Methane was inserted into the prototype system filled with activated vegetable carbon at reduced pressure (10 bar) using factorial design 2². In the desorption of the system, kinetics was raised to identify the best condition to be adopted between the conduction of the storage trials to allow activated carbon reuse. Activated carbon was characterized with N2 physisorption for the determination of textural characteristics, Helium gas pycnometry for quantification of particle density, and scanning electron microscopy for observation of the morphological structure. Under the conditions adopted in this study, an increase was observed in activated carbon adsorption capacity with decreasing temperature and flow rate during the evaluated range. With this study, it was possible to increase a cylinder storage capacity in approximately 3 times (34,56 V V-1) compared to the hollow cylinder (13,14 V V-1), proving the effectiveness of the adsorbent and the set of variables adopted. In addition, the kinetic study of methane desorption resulted in the adoption of 60 ºC for 30 min for the complete methane delivery.
