There was also great uncertainty of the production yields for SHEs. Closely related to the fission probability of SHEs in the ground-state, the survival of the compound nuclei formed after complete fusion was difficult to predict. Even the best choice of the reaction mechanism, fusion or transfer of nucleons, was critically debated. However, as soon as experiments could be performed without technical limitations, it turned out that the most successful methods for the laboratory synthesis of heavy elements are fusion-evaporation reactions using heavy-element targets, recoil-separation techniques, and the identification of the nuclei by generic ties to known daughter decays after implantation into position-sensitive detectors [13-15],... 

Observation of high-energy neutrinos would be strong evidence for acceleration of a primary beam of nucleons because such neutrinos are produced in hadronic interactions. Expected fluxes are low (Gaisser, Halzen Stanev, 1995), so large detectors are needed (Montaruli, 2003, Migneco, 2005). 

UHECRs are attractive because of their high centre-of mass energy. The proton-nucleon cross section for BH formation is very small compared to other hadronic processes. The neutrino-nucleon cross section for BH formation may be higher than the SM process, thereby giving interest to neutrino interaction. However, rate counting is not sufficient to prove black hole formation in the atmosphere. Discovery of BHs in UHECRs requires discrimination of BH and SM air showers. The extensive air shower (EAS) characteristics of these processes will differ, and with new detector methods and enough statistics expected from the new generation cosmic ray observatories, it may be possible to detect BH-induced EASs. 

The event rate of BH induced air showers can be used to set a limit on M The number of neutrino-nucleon BH events detected by a cosmic ray detector in time T is (Anchordoqui et al. 2002 2003) ...

Using nucleonic level detectors These usually employ gamma ray absorption or neutron backscatter techniques, but may also use gamma ray backscatter (Sec. 14.5). A case where a gamma ray absorption indicator solved a level control problem at the base of a column has been described (71). 

In 1951, Hal Anger read in the journal. Nucleonics, of the invention of the rectilinear scanner by Benedict Cassen at UCLA. He thought I can do better than that. He recognized that the mechanical movement of the crystal radiation detector over the patient s body as designed in the Cassen rectilinear scanner was a serious limitation, and set out to develop a gamma ray camera.

The detection efficiency of recoils with masses ranging from H up to Nb at energies from 0.05 to 1 MeV per nucleon has been investigated for ToF energy elastic recoil detection (ToF-E ERD) systems by Zhang et al. (1999). It is observed that the detection efficiency for the ToF-E detector telescope depends on the stopping power in the carbon foils, which in turn relies upon the recoil mass and energy. Furthermore, the limits of this behavior depend... 

The aim of ECT, therefore, is to reeonstruct the distribution of dielectric permittivity e(x,y), which corresponds to gas-solids distribution, from the capacitance measurements. It is worth pointing out, however, that the equation (2) is non-linear as it couples the dielectric permittivity distribution with the potential field, which results from that distribution. In simple terms, a change of permittivity in one place affects the electric field in the whole domain. This is unlike the nucleonic transmission tomography, where the introduction of a small object in the domain (see Figure 5) affects only the detectors in the objects shadow . This property of electrical field makes the reconstruction algorithms a much more challenging task than those...
