The photoneutron reaction $^{181}\rm{Ta}(\gamma,3n)^{178m,g}\rm{Ta}$ was investigated with the beam from NSC KIPT electron linear accelerator LUE-40. measurements were performed using residual $\gamma$-activity method. bremsstrahlung flux-averaged cross-sections $\langle{\sigma(E_{\rm{\gamma max}})}\rangle$, max}})}\rangle_{\rm{m}}$, max}})}\rangle_{\rm{g}}$ and isomeric ratio of products $d(E_...

We study the question of auction design in an IPV setting characterized by ambiguity. We assume that the preferences of agents exhibit ambiguity aversion; in particular, they are represented by the epsilon-contamination model. We show that a simple variation of a discrete Dutch auction can extract almost all surplus. This contrasts with optimal auctions under IPV without ambiguity as well as wi...

An overview of spin contamination and its relationship to broken-symmetry wave functions are presented. Spinoperator expectation-value formulas are developed for use with generalized, unrestricted, and restricted spin orbitals. Currentprojection techniques are reviewed and illustrated for a variety of current theoretical methods.

The development of Aspergillus flavus inoculation techniques has played an important part in developing corn (Zea mays L.) germplasm resistant to aflatoxin contamination. Corn genotypes evaluated for aflatoxin resistance in field studies must be artificially inoculated due to the sporadic nature of aflatoxin contamination from year to year. A number of different inoculation techniques are used ...

During the previous survey year (Year 2), a methodological issue arose which meant that our measures were no longer providing a reliable indication of how levels of contamination in chickens at retail were changing over time, or providing like for like comparisons between retailers. This methodological issue is explained in the January-March 16 report: www.food.gov.uk/sites/default/files/campy-...
