Phys. Rev. C 94, 014901 (2016) We analysed the $\phi$ meson production in central Ni+Ni collisions at the
beam kinetic energy of 1.93A GeV with the FOPI spectrometer and found the
production ...probability per event of $8.6 ~\pm~ 1.6 ~(\text{stat}) \pm 1.5
~(\text{syst}) \times 10^{-4}$. This new data point allows for the first time
to inspect the centrality dependence of the subthreshold $\phi$ meson
production in heavy-ion collisions. The rise of $\phi$ meson multiplicity per
event with mean number of participants can be parameterized by the power
function with exponent $\alpha = 1.8 \pm 0.6$. The ratio of $\phi$ to
$\text{K}^-$ production yields seems not to depend within the experimental
uncertainties on the collision centrality, and the average of measured values
was found to be $0.36 \pm 0.05$.
First measurement of subthreshold {sigma}(1385) production is presented. Experimental data are presented for Al+Al reactions at 1.9A GeV measured with the FOPI detector at SIS/GSI. The ...{sigma}(1385)/{lambda} ratio is found to be in good agreement with the transport and statistical model predictions. The results allow for a better understanding of subthreshold strangeness production and strangeness exchange reaction which is the dominant process for K{sup -} production below and close-to threshold.

New results concerning the production of neutral strange particles, K{sup 0} and {lambda} in Ni+Ni collisions at 1.93A GeV, measured with the FOPI detector at GSI Darmstadt, are presented. Rapidity ...density distributions and Boltzmann slope parameter distributions are measured in nearly the full phase space of the reaction. The observables are compared to existing K{sup +} and proton data. While the K{sup 0} data agree with previously reported K{sup +} measurements, the {lambda} distributions show a different behavior relative to that of protons. The strangeness balance and the production yield per participating nucleon as a function of the centrality of the reaction are discussed, for the first time at GSI Schwerionen Synchrotron (SIS) energies.

Results on K{sup +} and K{sup 0} meson production in {sub 44}{sup 96}Ru + {sub 44}{sup 96}Ru and {sub 40}{sup 96}Zr + {sub 40}{sup 96}Zr collisions at a beam kinetic energy of 1.528A GeV, measured ...with the FOPI detector at GSI-Darmstadt, are investigated as a possible probe of isospin effects in high-density nuclear matter. The measured double ratio (K{sup +}/K{sup 0}){sub Ru}/(K{sup +}/K{sup 0}){sub Zr} is compared to the predictions of a thermal model and a relativistic mean field transport model using two different collision scenarios and under different assumptions on the stiffness of the symmetry energy. We find good agreement with the thermal model prediction and the assumption of a soft symmetry energy for infinite nuclear matter, while more realistic transport simulations of the collisions show a similar agreement with the data but also exhibit a reduced sensitivity to the symmetry term.

There are so many meetings and the author honestly feels that most are taken for granted by company management and in all honesty, most are given very little consideration at all. In many cases this ...is a real loss. Each company must take care to send the right people to the appropriate conferences. In many cases machine operators and line supervisors should be the appropriate ones to attend certain conferences. Although a company may cut back on the number of safety trips, it really is imperative that enough training be allowed to keep your company abreast of current regulatory requirements. That is why belonging to the right group and sending the right people is so important.

The horrendous hazards associated with many natural disasters have direct impact on the health, safety and well-being of America's employees at home, at the workplace and commuting between the two. ...Too often Americans think of Occupational Safety & Health Administration (OSHA) only as an enforcement agency and they spend as much time as they have available in consulting, training and explaining the safe way to complete your processes. The storms and hurricanes are just an example of some of the oblique areas of OSHA's area of influence and many range far afield of machine guarding or LOTO where people usually confine their thoughts. But they can provide a company with what they need to both comply and protect their employees.

Corporate safety establishes the goals and sets the direction, but line supervision owns, and is responsible for its own safety process. Care must be taken however to ensure that there is enough ...overview to keep all regulatory requirements addressed, complied and abated with the same approach. The author can guarantee that if you have the very best program or process as measured by any number of world-class programs, it is inevitable that you will have an accident someday. Until there is an automatic system that enters an OSHA incident from the medical provider into the OSHA injury tracking system, there will be discrepancies. And that process is a long way off.
