Desempenho de gotejadores com uso de esgoto doméstico tratado

This paper aimed to determine the flow rate of drippers, their flow rate-pressure curve, their equation, their flow rate variation coefficient (VCq), as well as to evaluate the uniformity of water application of the Netafim drip pipe, Tiran 17 model, used for irrigation with domestic wastewater from treated household drain. After 1000 working hours, the blockage of some drippers decreased the uniformity of water application from 98% to lower than 60% and increased the flow variation coefficient to values higher than 0.29.

Atividade rizosférica de solo tratado com herbicida durante processo de remediação por Stizolobium aterrimum

This study aimed to evaluate the soil microbiota activity associated to S. aterrimum rhizosphere, during the phytoremediation process of a soil contaminated with trifloxysulfuron-sodium. S. aterrimum was cultivated in vases (6, 0 L) filled with soil, after trifloxysulfuron-sodium, at 7.5 g ha -1, was applied or not. Every 15 days after sowing (DAS), rhizospheric soil was collected for soil microbial respiration (amount of evolved CO 2) and microbial biomass carbon (MBC) analysis. To determine herbicide residues in the soil samples, after phytoremediation, Sorghum bicolor L. was cultivated as an indicator species, in addition to high performance liquid chromatography (HPLC) analysis. The microbiota associated to S. aterrimum rhizosphere showed to be sensitive to trifloxysulfuron-sodium and may be used as a microbiological indicator of disturbances caused by this herbicide in the environment. Regarding time for remediation, 45 days of development is enough for S. aterrimum to reduce residual trifloxysulfuron- sodium to a level not able to cause toxicity to the indicator plant.

Avaliação da segurança e eficácia de novo preenchedor à base de ácido hialurônico no tratamento dos sulcos nasolabiais e contorno dos lábios

Introduction: The use of dermal filling techniques for soft tissue augmentation has greatly increased in recent years. Hyaluronic acid is one of the most used temporary dermal fillers in the treatment of facial wrinkles, furrows, and folds due to its effectiveness and safety. Objective: To evaluate the efficacy and safety of Perfectha®, a new hyaluronic acid filler, for nasolabial folds and lip correction. Methods: Open, multicenter study comprising 87 women. Efficacy was evaluated by the Global Aesthetic Improvement Scale and the Wrinkle Severity Rating Scale. Safety was evaluated through observation and the reporting of side effects. Results: One week after the injection of the filler, improvement in nasolabial folds and lips was observed in 86% and 89% of the women, respectively. Mild or moderate transient inflammatory reaction and ecchymoses occurred in 15% and 9% of patients, respectively, mainly in nasolabial folds. Two patients presented labial herpes simplex after treatment of the lips. The good results were maintained in 76% and 57% of women for nasolabial folds and in 72% and 45% of women for lips after 3 and 6 months, respectively. Conclusion: Perfectha® was effective and safe for these indications.
