Computer program FPIP-REV calculates fission product inventory for U-235 fission

Computer program calculates fission product inventories and source strengths associated with the operation of U-235 fueled nuclear power reactor. It utilizes a fission-product nuclide library of 254 nuclides, and calculates the time dependent behavior of the fission product nuclides formed by fissioning of U-235

Let\u27s Observe!

Teaching the non-science major how to teach science is a challenge! No matter what science course is being taught, professors must model good teaching strategies that promote an inquiry approach that incorporates prior knowledge, connections, a social environment, relevance, and time to actively construct new understandings of scientific concepts

Half-BPS SU(N) Correlators in N=4 SYM

In this note we study half-BPS operators in N=4 super Yang-Mills for gauge group SU(N) at finite N. In particular we elaborate on the results of hep-th/0410236, providing an exact formula for the null basis operators algorithmically constructed there. For gauge groups U(N) and SU(N) we show that this basis is dual to the basis of multi-trace operators with respect to the two point function. We use this to extend the results of hep-th/0611290 concerning factorisation and probabilities from U(N) to SU(N). We also give a construction for a separate diagonal basis of the SU(N) operators in terms of the higher Hamiltonians of the complex matrix model reduction of this sector.Comment: LaTeX, 15 pages; comments added on large N limi

Abundance and Identification of the Leafmining Guild on Apple in the Mid-Atlantic States

The leafmining guild on apple in the northeastern United States was studied from 1983 to 1988. Ten species of leafminers, all Lepidoptera, were encountered during the sampling. Phyllonorycter spp. (P. blancardella and P. crataegella) were the most ubiquitous and most abundant throughout the region. Lyonetia speculella was also abundant in both managed and unmanaged orchards, indicating a potential to become a pest. Bucculatrix pomiloliella and Coptodisca splendorilerella were abundant in unmanaged orchards, but were only rarely found in managed orchards. Coleophora serratella, Stigmella pomivorella, Parornix geminatella, Tischeria malifoliella, and Recurvaria nanella were also found. A key to the most important leafminer species on apple in the mid-Atlantic states, based on leafmine characteristics, is presented

Understanding Something About Nothing: Radiation Zeros

Radiation symmetry is briefly reviewed, along with its historical, experimental, computational, and theoretical relevance. A sketch of the proof of a theorem for radiation zeros is used to highlight the connection between gauge-boson couplings and Poincare transformations. It is emphasized that while mostly bad things happen to good zeros, the weak-boson self-couplings continue to be intimately tied to the best examples of exact or approximate zeros.Comment: 12 pages, revtex.
