We present an experimental study of a topological excitation, interface, in a vertically vibrated layer of granular material. We show that these interfaces, which separate regions of granular material oscillating with opposite phases, can be shifted and controlled by a very small amount of additional subharmonic driving mixed with the harmonic driving signal. The speed and the direction of the ...

We describe a stochastic network interdiction model for deploying radiation detectors at border checkpoints to detect smugglers of nuclear material. The model is stochastic because the smuggler’s origin-destination pair, the type of material, and the level of shielding are known only through a probability distribution when the detectors are installed. We formulate a mixed-integer program for th...

Weaved Reality is a novel concept extending so-called Augmented Reality and Mixed Reality. It is not just a presentation level mixture of computerized virtual material and real material. It essentially contains knowledge as media and context-aware interface agents as a device for facilitating communication between human. This paper presents the concept of the weaved reality and a few prototype ...

The study evaluated the effectiveness of air biofiltration in rendering plants. The biofilter material comprised compost soil (40%) and peat (40%) mixed up with coconut fiber (medium A) and oak bark (medium B). During biofiltration average VOCs reduction reached 88.4% for medium A and 89.7% for medium B. A positive relationship of aldehyde reduction from material humidity (r = 0.502; α<0.05) wa...

objective: inflammation and oxidative stress is considered to have a crucial role in induction of nephropathy. curcuma longa (c. longa) and nigella sativa (n. sativa) have anti-inflammatory and antioxidant effects. this study was designed to investigate the effect of mixed hydro-alcoholic extract of n.sativa and c. longa on the oxidative stress induced by adriamycin (adr) in rat kidney. materia...

OBJECTIVES Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of MC as an anti-washout ingredient and CaCl2 as a setting time accelerator on the physical and biological properties of MTA. MATERIAL AND METHODS Test materials were divided into 3 groups; Group 1(control): distilled...

Biodiesel industry requires a cheaper and economical viable raw material that can replace the vegetable oil. Waste from animal and plant sources became the main option due the availability and cheap. In this study, coconut waste is used to produce biodiesel using methanol, acid sulfuric and KOH. In situ process is used, where all the catalyst, reagent and raw material is mixed together in one s...
