trains
In this work, pollution from carbonyl compounds was measured in the air of six trains.
      
The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers.
      
The questions of train aerodynamics have taken on great practical importance in connection with the rapid increase of the speeds of the modern trains.
      
In particular, of very great importance is the aerodynamic effect of trains on people and structures located near the tracks.
      
Solitary waves of this type ("solitary wave trains") are formed as a result of bifurcation from a nonzero wave number of the linear wave spectrum.
      
Sufficient conditions of existence of solitary wave trains in weakly dispersive media are also formulated.
      
Two-minute flash trains produced a substantial increase in the EEG power within the stimulation frequency with superposed oscillatory processes with different periods.
      
The programmer ensures the arbitrary generation of pulse trains with a minimum train step of 30 μs and recording of up to 30?000 10-bit amplitudes of spin-echo NMR signals with a minimum quantization step of 3 μs.
      
The mode of operation using testing signals in the form of trains of two to four acoustic shear oscillations is preferable to the impact excitation in tests of thin-wall pieces (pipes, sheets, T-bars, etc.).
      
Hydrological conditions on the path were characterized by the presence of a weak thermocline and a frequent occurrence of intense internal wave trains.
      
To locate a difficult target (at a small depth and a large distance), the beluga whale uses trains of pulses with a duration of up to 0.6 s and a time-pulse modulation.
      
The fast magneto-acoustic oscillations appear as trains of narrow-band signals with durations of 100-200 s, a positive frequency drift dν/dt=0.25 MHz/min, and frequency splitting δν=0.01-0.05 Hz.
      
Transient NQR signals in the effective field of multipulse trains
      
This paper is a theoretical analysis of time-dependent nutation and echo signals in the effective field of multipulse trains in NQR.
      
The dynamics of transients in an overdamped Josephson junction biased by trains of short current pulses with controllable parame
      
The freak wave phenomenon in the ocean is explained by the nonlinear dynamics of phase-modulated wave trains.
      
Self-generation of spin-wave envelope soliton trains with different periods
      
The self-generation of periodic spin-wave envelope soliton trains of microwave spin waves in active rings based on ferromagnetic films is studied experimentally.
      
The trains of bright solitons with different periods are self-generated in the same ring due to the frequency-selective control of the attenuation of spin waves circulating in an active ring.
      
Structures based on porous silicon por-Si/p-Si, both freshly prepared by chemical etching and aged, exhibit a temperature-dependent photovoltage at high levels of electron-hole pair generation by pulse trains of red and white light.
