A Low-Cost Constant-Moisture Automatic Irrigation System Using Dynamic Irrigation Interval Adjustment

Delivering a low-cost, reliable drip irrigation filtration system for micro-irrigation in developing countries

The cylindrical filters presently used in drip irrigation systems frequently clog, increasing pressure loss and lowering the flow rate through the filters. This work investigates alternative filtration strategies that increase the reliability of, and are compatible with, existing systems. To test different filtration strategies, a drip irrigation test setup was built to measure the pressure los...

Aural irrigation using the OtoClear Safe Irrigation System in children.

OBJECTIVE To evaluate the safety and efficacy of the OtoClear Safe Irrigation System for removing cerumen from the external auditory canal in children. METHODS Eligible subjects were 6 months-17 years of age with cerumen obstructing > or = 50% of the tympanic membrane (TM) from view (by otoscopy). Pneumatic otoscopy, tympanometry, and audiometry were performed followed by cleansing of the aff...

Developing Irrigation Conservation Strategies Using Soil Moisture Sensors and ET

Optimizing Soil Moisture Uniformity and Irrigation Management

This research is a study on the relationship of irrigation water treatments and soil moisture distribution uniformity (DU). Soil moisture distribution was based on long-term data sets that were collected during wet and dry soil conditions (from permanent wilting point to field capacity) using a novel electromagnetic sensor-based platform moving inside subsurface horizontal access-tubes. The irr...
