background: echinococcus granulosus cultivation is very important for improvement of different aspect of medical and veterinary researches. despite many advances in this case, there is a missing link for in vitro life cycle of adult worms and it is fertili-zation. regarding the researchers’ observations, self-fertilization can be done in worms living in dog intestine, but despite all sorts of e...

An optimized scheme can improve the navigation accuracy of RINS without changing inertial devices. In multi-position stop scheme, IMU remains stationary for most time, which makes motor control easier. However, installation errors and scale factor FOG cause platform misalignment after a certain angle rotation around horizontal axis, resulting in velocity error. Continuous suppress time-varying ...

We demonstrate that single photons from a rotating q-plate exhibit an entanglement in three degrees of freedom of spin, orbital angular momentum, and the rotational Doppler shift (RDS) due to the nonconservation of total spin and orbital angular momenta. We find that the rotational Doppler shift deltaomega = Omega((delta)s + deltal) , where s, l and Omega are quantum numbers of spin, orbital an...

to study the population structure of gibberella fujikuroi species complex, the causal agent of rice foot rot, samples were taken from different rice growing regions of guilan province in 2004. among fourty-one isolates recovered from different cultivars; three isolates did not produce microconidial chain. in order to study the sexual fertility and determine the mating type as well as mating pop...

A low diffusion particle method for simulating compressible low Knudsen number gas flows is modified for application to flows involving nonequilibrium distributions in rotational and vibrational energy modes. This method is closely based on the direct simulation Monte Carlo (DSMC) method, and has been developed for use in a strongly coupled hybrid scheme with DSMC. In simulations employing this...

Technological pressing equipment considered, its applicability for hydropress evaluated. main aspects joints on a base mechatronic press are established: increasing performance, stability. Mathematical models and an algorithm that regulate liquid fr...

We investigate the possibility of inducing a bosonic current which is rotational ( −→ ∇×−→v 6= −→ 0 ) in a pseudo 1D quasi-condensate confined in an optical toroidal trap. The stability of such a current is also analyzed using hydrodynamics approach. We find that such a current is uniform when the circular symmetry is preserved and energetically stable when the modes of elementary excitations a...

The translational motion of molecular ions can be effectively cooled sympathetically to temperatures below 100 mK in ion traps through Coulomb interactions with laser-cooled atomic ions. The distribution of internal rovibrational states, however, gets in thermal equilibrium with the typically much higher temperature of the environment within tens of seconds. We consider a concept for rotational...

Abstract. The rotational incremental pressure-correction (RIPC) scheme, described in Timmermans et al. [Int. J. Numer. Methods. Fluids., 22 (1996)] and Shen et al. [Math. Comput., 73 (2003)] for non-rotational Navier-Stokes equations, is extended to rotating incompressible flows. The method is implemented in the context of a pseudo Fourier-spectral code and applied to several rotating laminar a...
