We present the first computer graphics algorithm designed to simulate the aurora, a natural phenomenon of great visual beauty and considerable scientific interest. The algorithm is based on the current understanding of the physical origin of this natural display. The aurorae are mainly caused by high-energy electrons originating in the sun and entering the earth’s atmosphere in narrow regions c...

The autonomous sensory meridian response (ASMR) is an atypical sensory phenomenon involving electrostatic-like tingling sensations in response to certain sensory, primarily audio-visual, stimuli. The current study used an online questionnaire, completed by 130 people who self-reported experiencing ASMR. We aimed to extend preliminary investigations into the experience, and establish key multise...

the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...

In this research, the high-energy planetary mill was employed to produce nanocrystalline Ti-50Al(γ)(at%) powders. Initial powders were mechanically alloyed in 99.9999% and 90% purities of Argon and also Air atmosphere with alloying times up to 50h. The effect of impurity of Argon atmosphere on the microstructure and the rate of phase transformation of Ti-50Al were investigated during mechanical...

Historically, the visual manifestation of the “Black Drop effect,” the appearance of a band linking the solar limb to the disk of a transiting planet near the point of internal tangency, had limited the accuracy of the determination of the Astronomical Unit and the scale of the Solar System in the 18th and 19th centuries. This problem was misunderstood in the case of Venus during its rare trans...

abstractthe aim of intercultural translation is to communicate. communication is acted via verbal as well as visual means. the interaction of verbal and visual means of communication makes a set of complex situations which demand special attention in translation. one context in which the interaction of visual and verbal elements gets vital importance is children’s picture books. color is an int...

All ground-based astronomical observational data include effects of the Earth’s atmosphere, which is a wavelength dependent, spatially and temporally non-stationary optical medium. The atmosphere creates two different physical types of observational effects: it absorbs and scatters light in a wavelength dependent manner, and it blurs images by turbulence-induced refractive wave front perturbati...

  TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...

global warming is one of the major concerns in environmental issues. its effects are being exposed faster than anticipated recently. it causes adverse ecological and socioeconomical effects. the 4th assessment report issued by the u. n.’s intergovernmental panel on climate change (ipcc) states that it is appropriate to define global warming was caused by greenhouse gases due to human activities...

conclusions the analysis of the findings of the present study through considering the defined categories demonstrated that, to modify and correct the turbulent atmosphere-based management, several important measures are required and need to be continually monitored. results the result of data analysis was the theme “turbulent atmosphere-based management,” which consists of five categories as fo...
