Caspian kutum fish (Rutilus frisii) wild broodstocks were caught by gillnet during their upstream migration and subjected to short-time confinement stress and their physiological responses have been examined. Thirty fish (average weight of 1217.6 g) were divided into three experimental groups CO (control), OV (ovaprim) and CO+OV (cortisol+ovaprim) and placed into rearing tanks (10 fish tank-1; ...

A group of 59 workers (41 men and 18 women) employed in swine confinement areas was studied to assess the presence of acute and chronic respiratory symptoms and the prevalence of abnormalities in ventilatory function. A control group of 46 (31 men and 15 women) unexposed workers was studied for the prevalence of chronic respiratory symptoms. For both male and female swine confinement workers co...

Ground settlement is often the most serious concern when tunneling under an old city with numerous historic monuments. A successful engineering design under these conditions would require getting the most out of the ground strength parameters and avoiding any weakening maneuver throughout the operation. Knowing that surface settlement is highly affected by tunneling parameters in EPB shield tun...

We propose a numerical method for maintaining a dynamic rolling motion of animated gaseous phenomena, such as smoke, that avoids dissipation due to numerical error. We compensate for the errors induced by a semi-Lagrangian scheme using an error estimate for each time interval. We develop a new advection term and perform vortex advection based on a vorticity confinement force. Example simulation...

Quark confinement in MSSM QCD as a consequence of supersymmetry and instanton effects. Abstract It is shown, that instanton effects naturally produce quark confinement in MSSM QCD. The confinement scale, calculated from the first principles, is in a good agreement with the experimental data. The proposed explanation is quite different from the dual Higgs mechanism.

We review lattice evidence for the vortex mechanism of quark confinement and study the influence of charged matter fields on the vortex distribution. 1 Review of the vortex mechanism of quark confinement In the early days of QCD some people argued that quarks are confined due to the non-abelian nature of gauge-fields leading to attraction between flux-lines. But the abelian U(1) lattice gauge t...

We simulate a finite system of N confined electrons with inclusion of the Darwin magnetic interaction in two and three dimensions. The lowest-energy states are located using the steepest descent quenching adapted for velocity dependent potentials. Below a critical density the ground state is a static Wigner lattice. For supercritical density the ground state has a nonzero kinetic energy. The cr...

The problem of projecting the energy confinement properties of future devices is a long-standing one in toroidal confinement research. While substantial progress has been made in characterizing the transport properties of tokamaks and stellarators, no definitive understanding of the mechanism(s) of cross-field transport has been achieved. Thus, we are not in a position to perform “firstprincipl...
