Tests of the random phase approximation for transition strengths

We investigate the reliability of transition strengths computed in the random-phase approximation (RPA), comparing with exact results from diagonalization in full $0\hbar\omega$ shell-model spaces. The RPA and shell-model results are in reasonable agreement for most transitions; however some very low-lying collective transitions, such as isoscalar quadrupole, are in serious disagreement. We suggest the failure lies with incomplete restoration of broken symmetries in the RPA. Furthermore we prove, analytically and numerically, that standard statements regarding the energy-weighted sum rule in the RPA do not hold if an exact symmetry is broken.Comment: 11 pages, 7 figures; Appendix added with new proof regarding violation of energy-weighted sum rul

Largest Gold Fish Hatchery in the World. Storage House and a Few of the 200 Ponds, Grassyfork Fisheries, Martinsville, Indiana

In 1902, Eugene Shireman turned his Martinsville swampland into the Grassyfork Fisheries. It became the largest goldfish supplier in the world with over 2 million fish per year. Visitors could also enjoy displays of aquariums, fountains, and water gardens.Morgan County JourneyMessage to: Miss Eva: Daleville, Ind. Hello Miss, how is Granpa & Ma. Ha Ha. Will see you all soon.

Mechanical transmission of Cryptosporidium parvum oocysts by flies

Long term field studies and laboratory experiments demonstrated that synanthropic filth flies can mechanically transmit infectious oocysts of Cryptosporidium parvum, an anthropozoonotic protozoan parasite which significantly contributes to the mortality of immunocompromised or immunosuppressed people. C. parvum oocysts are acquired from unhygienic sources, and can pass trough fly gastrointestinal track without alteration of their infectivity and can be subsequently deposited on visited surfaces. Transmission of the oocysts by adult flies occurs via: (1) mechanical dislodgement from the exoskeleton; (2) fecal deposition; and (3) regurgitation, i.e., vomits. Filth flies can cause human or animal cryptosporidiosis via deposition of infectious oocysts on the visited foodstuf, and the biology and ecology of synanthropic filth flies indicate that their potential for mechanical transmission of C. parvum is high

INFLATION UNCERTAINTY AND GROWTH: EVIDENCE FROM PANEL DATA *

This paper explores empirically the link between inflation uncertainty and economic growth through a panel data analysis with a data set from OECD economies that covers the period from 1969 to 1999 and the GARCH methodology. The main results point out that inflation uncertainty has an adverse impact on economic growth in the majority of the cases under investigation Copyright Blackwell Publishing Ltd/ University of Adelaide and Flinders University 2005..
