This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers for milling of drill cuttings. An F.E model of the process mill was constructed using dimensions similar to ...

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic machines. Nonlinearities due to the high level of acoustic pressure generate DC flows that are superimposed on the ...

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

The fixed beds have the advantage of large heat transfer area, for they are used in some designs of innovative nuclear reactors as the reactor FBNR. Inside of study of fixed beds is important to define the following parameters: flow minimum and velocity profile of cooling fluid, temperature profile of cooling fluid and the fuel elements.

Microalgae can be directly used in health food or as biofilters for waste water treatment. They also have numerous commercial applications in cosmetics, aquaculture and chemical industry as a source of highly valuable molecules, e.g., polyunsaturated fatty acids, and they are increasingly recognized as a promising source for biodiesel production. To realize the full potential of microalgae, ...

INTRODUCTION Enhancement of a single-photon emission is a great demand in recent science and applications, including development novel class of light sources, encoded information transfer and biological imaging [1, 2, 3]. Fluorescence can be improved through excitation and emission enhancement. Improvement of these two processes can be realized by using the near-field enhancement accompanying ...

SOFC is a high temperature electrochemical device known for its fuel flexibility. Apart from using pure hydrogen, it can utilize CO (carbon monoxide), CH4 (methane) or any other higher hydrocarbon. Since methane is highly researched hydrocarbon fuel, it was chosen to start with. The most prominent problem faced while using hydrocarbon fuel in SOFC is the formation and deposition of carbon on the ...

Electrodermal Activity (EDA) is a measure of changes in the conductivity of the skin. It has have been found to be indicative of the individual’s autonomic nervous activity which is correlated to their stress and emotional state. These conductivity changes are tracked by injecting a small electric current directly into the skin and measuring the induced voltage drop over time. With increase in ...
