Flow coefficients v_{n} for n=2, 3, 4, characterizing the anisotropic collective flow in Au+Au collisions at sqrt[s_{NN}]=200  GeV, are measured relative to event planes Ψ_{n}, determined at large rapidity. We report v_{n} as a function of transverse momentum and collision centrality, and study the correlations among the event planes of different order n. The v_{n} are well described by hydrodynamic models which employ a Glauber Monte Carlo initial state geometry with fluctuations, providing additional constraining power on the interplay between initial conditions and the effects of viscosity as the system evolves. This new constraint can serve to improve the precision of the extracted shear viscosity to entropy density ratio η/s.

Back-to-back hadron pair yields in d+Au and p+p collisions at sqrt[s_{NN}]=200  GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity |η|<0.35 and the associated hadron at forward rapidity (deuteron direction, 3.0<η<3.8). Pairs were also detected with both hadrons measured at forward rapidity; in this case, the yield of back-to-back hadron pairs in d+Au collisions with small impact parameters is observed to be suppressed by a factor of 10 relative to p+p collisions. The kinematics of these pairs is expected to probe partons in the Au nucleus with a low fraction x of the nucleon momenta, where the gluon densities rise sharply. The observed suppression as a function of nuclear thickness, p_{T}, and η points to cold nuclear matter effects arising at high parton densities.

We present measurements of J/ψ yields in d+Au collisions at sqrt[s_{NN}]=200  GeV recorded by the PHENIX experiment and compare them with yields in p+p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/ψ rapidity (-2.2<y<2.4) with high statistical precision and are compared with two theoretical models: one with nuclear shadowing combined with final state breakup and one with coherent gluon saturation effects. In order to remove model dependent systematic uncertainties we also compare the data to a simple geometric model. The forward rapidity data are inconsistent with nuclear modifications that are linear or exponential in the density weighted longitudinal thickness, such as those from the final state breakup of the bound state.

The addition of certain amounts of the zeolite mineral klinoptilolith to freshly obtained bird feces led to the retention of nitrogen--up to 14 per cent and more--as compared with feces without zeolite in storage. The addition of the mineral produced also a deodorizing effect in neutralizing the offensive smelling accompanying the putrefaction process.

The passage of sedimented refuse water from pig-breeding farms through a clinoptilolit filtre of a grain size of 1.0 up to 0.5 mm leads to a decrease in BNO5 (the biochemical need of water) of such water by about 21 per cent. This is of interest to the purification of wastage waters associated with the everyday life as well as of refuse waters linked with animal-breeding activity, with special reference to keeping waters clean.

Studied were 336 sera of vaccinated and challenged chickens, 76 egg extracts, and 36 birds following challenge for the presence of serum antibodies against the Newcastle disease virus, using the hemagglutination-inhibition reaction, the agar gel diffusion precipitation reaction, and the virus-neutralizing test. The values of the antihemagglutinins, precipitins, and virus-neutralizing antibodies were investigated in relation to the immunobiologic resistance of birds to a velogenic Newcastle disease virus. A correlation was found between the antihemagglutinins and the neutralizing antibodies in broilers, aged 30-60 days, treated with an aerosol vaccine La Sota, and in henlayers treated muscularly with the Komarov vaccine. The presence of antihemagglutinin titers of 1:40 and higher values or positive neutralizing indices in the investigated birds were able to provide immunobiologic protection in challenging with a velogenic virus. Precipitins were detected in the blood sera of the challenged birds, which made reasonable their use as a sign pointing to the passage of a velogenic virus through the birds. The lower number of cases with positive precipitin reactions in the vaccinated birds speaks against using objectively this index for the evaluation of the immunologic status.
