1. Comparison of automated irrigation systems using an in vitro ureteroscopy model
ABSTRACT Introduction: Two automated irrigation systems have been released for use during endoscopic procedures such as ureteroscopy: the Cogentix RocaFlow® (CRF) and Thermedx FluidSmart® (TFS). Accurate pressure control using automated systems may help providers maintain irrigation pressures within a safe range while also providing clear visualization. O

2. DAMS SAFETY INDEX (DSI): A REASSESSMENT OF THE PARAMETERS OF ANALYSIS
ABSTRACT Dams provide a water supply, irrigation and power generation. However, the economic, social and environmental impacts are serious when they rupture. It is important that dams continue to function properly and are constantly evaluated for their safety and functionality. Contrary to general belief, small dams are the ones that present the most problem

6. Irrigation and Light Access Effects on Coffea arabica L. Leaves by FTIR-Chemometric Analysis
Coffee bean chemical compositions has been extensively studied. However, there is a small amount of research on other parts of the coffee plant, including leaves. Fourier transform infrared (FTIR) spectral profiles of Coffea arabica L. cv. IAPAR 59 leaf extracts from a simplex-centroid design were studied by principal component analysis (PCA) to evaluate the

7. PRODUCTIVITY AND NUTRITIVE VALUE OF TIFTON 85 IN SUMMER, WITH AND WITHOUT IRRIGATION UNDER DIFFERENT NITROGEN DOSES
ABSTRACT The pasture irrigation has expanded, mostly in small areas in order to boost the production system, along with the use of soil improvement techniques and high-productivity grasses. Thus, this study, carried out on a small dairy farm property, aimed to evaluate the productivity, botanical composition and nutritive value of Tifton 85 with different ni

8. Method to evaluate the efficiency of manual overhead irrigation in citrus rootstock liner production
ABSTRACT Brazil produces grafted citrus seedlings in closed screen houses to reduce pest and disease incidence. Irrigation is usually performed by hand using either breaker nozzles or drilled polyvinyl chloride (PVC) pipe wands on garden hoses. Rootstocks are produced in cone-shaped containers filled with soilless potting mix. Since the containers have a sma

9. Withdraw of the Ureteroscope Causes Fragmented Ureter Stones to Disperse
Introduction Ureteroscopy has improved from the first use of ureteroscope in the 1970's. Although the success rate increased in the last years, (1) new treatment techniques are being developed for impacted and large proximal ureter stones (2). Pneumatic lithotripsy has high efficiency with low complication rates (2). However, in case of steinstrasse and lar

11. Effect of hydraulic head in the uniformity of irrigation and fertigation under drip system / Efeito da carga hidrÃulica na uniformidade da irrigaÃÃo e fertirrigaÃÃo em sistema de gotejamento
The irrigation tracked by gravity is a technique applied by the family farming that has been spread in Brazil and is used in social programs of some States or directly traded to producers. Irrigation systems have simplified management and let it cheaper. They intensify agricultural yield, increase the prospects of life in the countryside and, therefore, sett

12. Performance and radial distribution profiles of a variable flow rate sprinkler developed for precision irrigation
Variable rate sprinklers (VRS) have been developed to promote localized water application of irrigated areas. In Precision Irrigation, VRS permits better control of flow adjustment and, at the same time, provides satisfactory radial distribution profiles for various pressures and flow rates are really necessary. The objective of this work was to evaluate the
