technology foresight is a methodology for making the complexity and advanced nature of new technologies of future more comprehensible and transparent. the objective of this survey is to analyze and interpret weakness and strength of the current situation of iran organizations regarding utilization of foresight activities of developing new technologies and its influence over the country by usin...

Observed crest speeds of maximally steep, breaking water waves are much slower than expected. Our fully nonlinear computations of unsteadily propagating deep water wave groups show that each wave crest approaching its maximum height slows down significantly and either breaks at this reduced speed, or accelerates forward unbroken. This previously noted crest slowdown behavior was validated as ge...

the effects of different sources of carbon, nitrogen and some of trace elements on cultivation of bacillus thuringiensis h14 were studied. glucose, glycerol, sodium acetate, (nh4)2so4, corn steep liquor, yeast extract, hydrolyzed casein, ca2+, mg2+ and mn2+ were the main parameters evaluated by plackett-burman statistical method. all elements have insignificant effect on germination while spore...

A method for real time QRS detection by assessment of the signal steep slopes is proposed. It is based on comparison of the absolute value abs(D) of the differentiated electrocardiogram (ECG) to a varying threshold value. The method is independent of threshold and weighting constant. It is adaptive and self-synchronized to the steep slope of the QRS, regardless of the amplitude and the sampling...

A wind-borne plume of sex pheromone from a female moth or a synthetic source has a fine, filamentous structure that creates steep and rapid fluctuations in concentration for a male moth flying up the plume's axis. The firing rates from single antennal neurons on Agrotis segetum antennae decreased to nearly zero within seconds after the antennae were placed in a pheromone plume 70 cm downwind of...

Non-breaking tsunami waves run-up on steep slopes can cause severe damages to coastal structures. The estimation of the wave run-up rate caused by tsunami waves are important to understand the performance and safety issues of the breakwater in practice. In this paper, an Incompressible Smoothed Particle Hydrodynamics method (ISPH) method was utilized for the 2DV numerical modeling of nonli...
