We extract downward-propagating Pand S-waves from industrial noise generated by human and/or machine activity at the surface propagating down a borehole at Cold Lake, Alberta, Canada, and measure shear-wave splitting from these data. The continuous seismic data are recorded at eight sensors along a downhole well during steam injection into a 420–470-m-deep oil reservoir. We crosscorrelate the w...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
the aim of this study was to investigate the effect of 8 weeks of endurance and resistance training on the activity of g4 acetyl cholinesterase in fhl and soleus muscles of rats. 24 male wistar rats (age: 10 weeks and weight: 171.94±8.961 gr) were randomly divided into 3 groups (control, endurance training (et) and resistance training (rt)). et and rt groups carried out 8 weeks (5 sessions per ...
Introduction: Skeletal muscle is a flexible and ever changing tissue and the role of costameric proteins in its response to different stimuli is not well defined. The aim of this study was to investigate the effect of progressive resistance exercise on β1 integrin and vinculin proteins in fast and slow twitch skeletal muscles of male rats. Methods: Twelve male Wistar rats (weight: 298±5.2 gr...
Background: The slow-freezing method is one of the most popular techniques to freeze human oocytes and it is also used in routine in vitro-fertilization (IVF) programs, particularly in those countries where embryo freezing is not allowed. Slow-freezing damages some of the structures of the egg, among which the meiotic spindle (MS) and the zona pellucida (ZP). Polarized Light Microscopy (PLM) pe...
We experimentally observe polarization-locked vector solitons in a passively mode-locked fiber laser. The vector soliton pulse is composed of components along both principal polarization axes of the linearly birefringent laser cavity. For certain values of birefringence and pulse energy these components propagate with a constant relative optical phase of 6p/2, and hence the pulse has a fixed el...
Propagation of solitonlike pulses in birefringent nonlinear fibers has attracted much attention in recent years [1—14]. The equations that describe pulse propagation in these fibers have been derived by Menyuk [1]. These equations are quite complicated and can be solved only in an approximate way for certain specific cases. Two main cases have been studied in depth: high and low birefringent fi...
