Do we need to attend to an object in order to be conscious of it, and are the objects of our attention necessarily part of our conscious experience? A tight link between attention and consciousness has often been assumed, but it has recently been questioned, on the basis of psychophysical evidence suggesting a double dissociation between top-down attention and consciousness. The present review ...

In this paper, we proposed a new structural protective device based on a silicon controlled rectifier (SCR) to protect ESD (Electrostatic Discharge) of an integrated circuit. The proposed device features latch-up immunity in a normal operation state by the low holding voltage of the existing SCR based PSD protective device. The proposed device was analyzed to figure out electrical characteristi...

Learning to predict threat depends on amygdala plasticity and does not require auditory cortex (ACX) when threat predictors (conditioned stimuli, CS) are simple sine tones. However, ACX is required in rodents to learn from some naturally occurring CS. Yet, the precise function of ACX, and whether it differs for different CS types, is unknown. Here, we address how ACX encodes threat predictions ...

economic value of natural resources is increased via tourism resources function. natural environment in the desert area has great potential for attracting tourists and in this respect it has a nonmarketable value. making these values marketable may lead to rise up the economic value of natural environment in the desert area. one of the most important natural environments in the desert areas of ...

A bioreactor refers to any manufactured or engineered device that supports a biologically active environment. These kinds of reactors are designed to treat wastewater treatment. Volumetric mass transfer coefficient and the effect of superficial gas velocity, as the most important operational factor on hydrodynamics, in three-phase airlift reactors are investigated in this study. The experiments...

In this study, the composite material with composition of MgH2-5 wt% SiC has been prepared by co-milling of MgH2 with SiC powder. The effect of milling time and additive on MgH2 structure, i.e. crystallite size, lattice strain, particle size and specific surface area, and also hydrogen desorption properties of obtained composite was evaluated by thermal analyzer method and compared with pure un...
