The elimination of the FexAly type phases was considered the solution to low ductility presented in aluminum-steel welded joints. Recently, the researches do not seek the suppression but the control of the thickness of these compounds. In this work, Al-Fe joints were manufactured by solid state and fusion welding, looking for controlling the formation of intermetallic comp...

A new conceptual non-thermal anti-icing system for helicopter rotor blades is introduced. Theoretical calculations predict that certain ultrasonic modes generated by horizontal shear waves produce sufficient interface stresses between a host structure and ice to remove the accreted ice layer. Experimentally obtained ultrasonic shear dispersion curves are compared to theoretical predictions for ...

BACKGROUND Infection with Porcine Epidemic Diarrhea Virus (PEDV) causes vomiting, diarrhea, and dehydration in young pigs. The virus made its first appearance in the U.S. in 2013, where it caused substantial neonatal mortality and economic losses in the U.S. pork industry. Based on outbreak investigations, it is hypothesized that the virus could be transmitted through contaminated feed or conta...

Of utmost concern in storm water treatment today is the removal of dissolved phosphorus. One method to effectively determine the phosphorus removal capacity of different sand filtration media is controlled, well mixed experiments called batch studies. Batch studies with an initial phosphorus concentration typical of storm water were conducted at the University of Minnesota on C 33 sand, calcare...

We describe CLAD, an implemented advisor system in the domain of clinical medicine. CLAD assists a human physician in making decisions about diagnosing and treating patients. CLAD monitors the transcript of an ongoing dialog between the physician and a patient, builds and augments a mental model of the patient and suggests courses of action to the physician. CLAD can also explain its decisions ...

We investigated the galvanic corrosion behavior of aluminum alloy in contact with carbon steel during accelerated testing by evaluating current and morphology coupled specimen. Electrochemical polarization curve was acquired before after testing, only detected for dissolution. Aluminum next to more severely corroded than remote aluminum. Corrosion also observed steel, although its dissolution n...
