Clay Improvement with Burned Olive Waste Ash
Olive oil is concentrated in the Mediterranean basin countries. Since the olive oil industries are incriminated for a high quantity of pollution, it has become imperative to solve this problem by developing optimized systems for the treatment of olive oil wastes. This study proposes a solution to the problem. Burned olive waste ash is evaluated for using it as clay stabilizer. In a laboratory, ...
متن کاملElectronic Ballast Platform - EBP
In this paper will be reported the implementation of a flexible platform to study electronic ballasts systems. The platform is a microcontrolled and FPGA-based system and was developed to generate command signals to the half bridge inverter. A specific hardware using FPGA was developed to generate the switches signals command. This hardware is responsible for the autonomous frequency (FM) and p...
متن کاملDigitally Addressable DALI Dimming Ballast
A digitally addressable digital dimming ballast has been developed. It conforms to DALI standard requiring very few parts and operates at very low power. Applications include building management or studio lighting where it is desired to control single or groups of lamps for conserving energy, performing lamp maintenance or creating prefect light quality. The design includes the digital dimming ...
متن کاملUse of Ballast Support Condition Back-Calculator for Quantification of Ballast Pressure Distribution Under Concrete Sleepers
In North America, most rail corridors are constructed using ballasted track. Monitoring the ballast support condition and improving upon current sub-structure/ballast maintenance strategies will ensure safe railroad operations. However, it is inherently difficult to evaluate the pressure distribution at the sleeperballast interface. Researchers at University of Illinois at Urbana-Champaign (UIU...
متن کاملNutrition of burned patients.
Burns form 5-12% of all traumas. About 2,200 of patients are annually hospitalized in Lithuania. In most cases people of the employable age get burned. The treatment is often long-lasting, and afterwards recovered patients often have invalidity from burn sequels. The mortality of hospitalized burned patients is about 10%. The most common causes of death are pulmonary edema, pneumonia, sepsis an...
