impulse buying behavior is one of main concepts in marketing. it is affected on various factors such as cultural factors, psychological factors, personal factors and positional factors. buying can be done because of different reasons (including of needing a production) and this fact aids marketers to better understand consumers’ behavior. impulse buying is one of pervasive aspect of consumer be...

Visual information transmitted in the form of digital images is becoming a major method of communication in the modern age, but the image obtained after transmission is often corrupted with noise. The received image needs processing before it can be used in applications. This paper represents a robust statistics based filter to remove salt and pepper noise in digital images. The function of the...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

A series of psychoacoustic experiments were carried out to explore the relationship between an objective measure of reverberation echo density, called the normalized echo density (NED), and subjective perception of the time-domain texture of reverberation. In one experiment, 25 subjects evaluated the dissimilarity of signals having static echo densities. The reported dissimilarities matched abs...

A finite impulse response (FIR) equalizer is practically employed in conjunction with the Viterbi detector for data detection process in magnetic recording channels. However, the FIR equalizer with a large number of taps is required at high density storage channels. It is well-known that an infinite impulse response (IIR) filter with a small number of taps can closely approximate such an FIR fi...

Relativistic exchange current corrections to the impulse approximation in low and intermediate energy neutrino–nucleus scattering are presented assuming non–vanishing strange quark form factors for constituent nucleons. Two–body exchange current operators which treat all SU (3) vector and axial currents on an equal footing are constructed by generalizing the soft–pion dominance method of Chemto...

Microfabricated electrospray thrusters could revolutionize the spacecraft industry by providing efficient propulsion capabilities to micro and nano satellites (1–100 kg). We present the modeling, design, fabrication and characterization of a new generation of devices, for the first time integrating in the fabrication process individual accelerator electrodes capable of focusing and accelerating...

The thermal properties of wood in the green state have been determined by the transient plane source (TPS) technique. Data are presented on thermal conductivity ( λ ), heat capacity ( C ), and thermal diffusivity ( κ ) at moisture contents (MCs) above the fiber saturation point, which are based on measurements using the HotDisk ® apparatus. Four wood species (Douglas fir, beech, birch, and spru...

We calculate the force operator for a charged particle in the field of an Aharonov–Bohm flux line. Formally this is the Lorentz force, with the magnetic field operator modified to include quantum corrections due to anomalous commutation relations. For stationary states, the magnitude of the force is proportional to the product of the wavenumber k with the amplitudes of the ‘pinioned’ components...

The anaesthetic potency of a substance is closely related to its lipophilicty. This has been interpreted as evidence for a lipid mechanism of action for anaesthesia. However, with the success of the conductance based Hodgkin-Huxley model for the nerve impulse, the scientific community shifted to considering protein ion-channels the cellular target for anaesthetics. Today, the lipid hypothesis h...
