title: Two-shift operation mode can improve the efficiency and comfort of flexible ureteroscopic holmium laser lithotripsy for the treatment of renal calculi larger than 1.5cm

description: ABSTRACT Purpose: To compare two-shift operation mode and single player mode different impact on surgical results and operator comfort in flexible ureteroscopic holmium laser lithotripsy for renal calculi larger than 1.5cm. Materials and Methods: From december 2017 to december 2018, 92 patients with renal calculi admitted to Qilu Hospital and were treated through flexible ureteroscopy. They were randomized in two-shift group (n=50) and single player group (n=42). The operative time, blood loss, hospitalization stay after operation, residual fragments (≥4mm) rate, fragmentation speed, postoperative complications and operator's fatigue score were compared. Results: There was no significant difference between two groups regarding age, gender, illness side, stone size, blood loss, operative time, postoperative hospitalization stay, complications, etc (p &gt;0.05). The fragmentation speed was 44.5±20.0mm3/min in two-shift group compared with 34.2±17.3mm3/min in single player group (p=0.037). Residual fragments (≥4mm) rate after first surgery was 18% in two-shift group, while the residual fragments (≥4mm) rate was 40.5% after first surgery in single player group (p=0.017). The total fatigue score of two-shift group was 8.4 compared to 29.9 in single player group (p &lt;0.001). Conclusion: In flexible ureteroscopic holmium laser lithotripsy for the treatment of renal calculi larger than 1.5cm, two-shift operation mode can raise the fragmentation speed and stone clearance rate, as well as significantly lower operator's fatigue level and improve operator's comfort.

title: Use of low impact development techniques to control hydrological impacts

description: ABSTRACT The disordered urban growth has several implications for the drainage of urban watersheds, especially regarding changes in runoff. The Mãe d’água watershed in Viamão/RS in Brazil portrays well this problem. Therefore, the following issue arises: are there LID solutions compatible with the mitigation of hydrological impacts in situations of urbanization under consolidation? In this respect, simulations were performed for three different urbanization scenarios, being: the current, the future, and the possible scenarios. The current scenario represents the current system. The future scenario is represented by the implementation of the current Master Plan of Viamão, with permeability rate of 10% in the lots. The possible scenario was presented through the insertion of LID measurements (vegetative swales and permeable pavements) and with the lot permeability rates of the future scenario. The scenario simulations were performed in the SWMM model for design rainfalls with a return period of 2, 5, 10 and 20 years. The most critical scenario regarding drainage problems was the future scenario. In the possible scenario, even with mitigating measures, there are still flood volumes in some points, but the LIDs reduced the volume flowed in the watershed by up to 14% for the RP of 2 years. The LID measurements showed best performance for rainfalls with lower return period. The best efficiency in the reduction of runoff volumes was through the maintenance of soil permeability rates. However, LIDs help to reduce surface runoff, being a viable alternative for areas that are already consolidated.

title: AUTOMATED INDIVIDUAL TREE DETECTION IN AMAZON TROPICAL FOREST FROM AIRBORNE LASER SCANNING DATA

description: ABSTRACT Light Detection and Ranging (LiDAR) derived individual tree crown attributes can potentially serve as a tool for ecology and forest dynamics studies and reduce field inventory costs. In this study, four methods of individual tree detection (ITD), Watershed, Silva et al. (2016), Dalponte and Coomes (2016), and Coomes et al. (2017), were evaluated in a tropical forest under sustainable forest management, situated in the State of Rondônia, Brazil. An automated tree matching procedure was developed in order to minimize the error when matching individual tree count from LiDAR and field data. In order to compare the four methods, results were expressed in recall, precision, and F score. Silva et al. (2016) outperformed the other methods, detecting 48% of trees with 46% of precision. Omission of trees was the leading source of error, caused primarily by overlapped trees in lower vegetation. However, errors of over-segmentation were relevant, caused by large and heterogeneous crowns that had multiple detections. Current canopy height model-based methods are ineffective to tropical forests, due to its complexity, which present a challenge for ITD algorithms. We believe that future studies that use complete 3D information from the point cloud, and multi-layer approaches should help to improve the accuracy of individual tree detection.

title: Biosurfactant production: intracellular manoproteins and extracellular sophorolipids by Saccharomyces cerevisiae

description: ABSTRACT Biosurfactants implicate many environmental applications, being produced by a wide range of microorganisms. Those from the Saccharomyces cerevisiae yeast are still poorly studied for environmental purposes and are non-toxic. The aim of the study was the production of intra- and extracellular biosurfactants by the Saccharomyces cerevisiae yeast. The yeast was grown in cultured medium containing 0.5% yeast extract, 1% peptone and variable concentrations of sucrose and oily inducers. Inducers used were glycerol, soybean oil and diesel oil. Experiments were conducted for 96 h, and the daily production of biosurfactants was evaluated by reducing surface tension and stabilizing emulsions. Extracellular biosurfactant was extracted from the obtained biomass, with subsequent precipitation and chemical characterization by mass spectrometry. The highest extracellular emulsifier yields were achieved with glycerol inductor (0.20 UE h-1) and soybean oil (0.21 UE h-1) in 48h of cultivation. In later tests performed with increasing concentration of inducer, an increase in extracellular yields was noticed in these experiments (0.45 UE h-1 for glycerol and 0.30 UE h-1 for the soybean oil). The greatest reduction in surface tension was 9.89% in 72 h for diesel oil inducer. The reduction of surface tension combines with the increase of emulsifying activities in an important indicator of the use of hydrophobic substrate by the microorganism. The study confirms an increase in the production of extracellular biosurfactants when optimizing cultivation. The production of intracellular biosurfactants has also been verified, however the process of cellular disruption increases the cost of the bioprocess.

title: Performance of 'Jaffa' sweet orange on different rootstocks for orchards in the Brazilian Northeast

description: Abstract: The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.

title: Outcomes of Cases of Prenatally-Diagnosed Congenital Pulmonary Airway Malformation

description: Abstract Objective To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM). Methods We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis. Results The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. Themedian gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case). Conclusion A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.

title: Prevalence and surgical management of pubic hypertrophy in hypospadias patients: results from a high-volume surgeon

description: ABSTRACT Introduction: Pubic hypertrophy, defined as an abnormal and abundant round mass of fatty tissue located over the pubic symphysis, is frequently underestimated in patients with hypospadias. We examined the prevalence of this condition, as well as the outcomes associated with its surgical treatment. Material and methods: Within 266 hypospadias patients treated at our clinic, we assessed the prevalence of pubic hypertrophy, and we schematically described the surgical steps of pubic lipectomy. Multivariable logistic regression (MLR) tested for predictors of pubic hypertrophy. Finally, separate MLRs tested for predictors of fistula and any complications after pubic lipectomy. Results: Of 266 hypospadias patients, 100 (37.6%) presented pubic hypertrophy and underwent pubic lipectomy. Patients with pubic hypertrophy more frequently had proximal hypospadias (44 vs. 7.8%), disorders of sex development (DSD) (10 vs. 0.6%), cryptorchidism (12 vs. 2.4%), and moderate (30°-60°) or severe (&gt;60°) penile curvature (33 vs. 4.2%). In MLR, the location of urethral meatus (proximal, Odds ratio [OR]: 10.1, p&lt;0.001) was the only significant predictor of pubic hypertrophy. Finally, pubic lipectomy was not associated with increased risk of fistula (OR: 1.12, p=0.7) or any complications (OR: 1.37, 95% CI: 0.64-2.88, p=0.4) after multivariable adjustment. Conclusions: One out of three hypospadias patients, referred to our center, presented pubic hypertrophy and received pubic lipectomy. This rate was higher in patients with proximal hypospadias suggesting a correlation between pubic hypertrophy and severity of hypospadias. Noteworthy, pubic lipectomy was not associated with increased risk of fistula or any complications.

title: MINI-CUTTING TECHNIQUE FOR VEGETATIVE PROPAGATION OF Paratecoma peroba

description: ABSTRACT Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagation protocol for P. peroba using the mini-cutting technique. In the first experiment, were tested five concentrations of indolbutiric acid (IBA; 0, 1, 2, 4 and 8 g.L-1) and two types of substrates (sand and a commercial substrate based on ground Pinus bark, coconut powder, and mineral additives). In the second experiment, were tested three types of mini-cuttings (apical of 6 cm and 10 cm, and intermediary of 4 cm) and two leaf area sizes (total leaf area and reduced to 50% of leaf area). The results showed that P. peroba could be vegetatively propagated using the mini-cutting technique with up to 82.5% rooting. There was only 5.6% of mini-cutting rooted in sand. High concentrations of IBA promotes decrease in rooting and number of roots. The 10 cm apical mini-cuttiing tend to form clones with better quality standards. The maintenance of the leaf area promotes the attainment of roots with greater root surface area, volume and dry mass of P. Peroba plants.
