Integration of organic poultry in whole farm systems: manure nutrient budgets
This report was presented at the UK Organic Research 2002 Conference. The aim of this project was to examine how rotations incorporating organic poultry use the cycling of nutrients between soil, crops and birds. Poultry studies have measured nutrient values of manure in slow growing meat birds at about day 81 when fed typical broiler rations versus âLabel Rougeâ rations. Nutrient (N, P, K) balances were constructed to assess the viability of integrating poultry production within a theoretical organic rotation. The readilyplant- available nitrogen in manure from Ross 308 birds fed either presumed non-limiting rations or Label Rouge rations was within the range reported for intensive broilers. For ISA 657 birds, the manure readily-plant-available nitrogen was similar to the mean value reported for broilers, when fed presumed non limiting rations, but towards the lower range when fed Label Rouge rations. As breed growth and feed intakes differ it is suggested that to optimise the utilisation of nutrients, the nutrient content of table bird manures should be checked prior to land application. The nutrient budgets were similar for N and P regardless of the length of rotation or form of poultry production. On average, there was a surplus of 85 kg/ha N over all the scenarios. There tended to be a deficit of K in all scenarios (average: 10 kg/ha)
Recent MOST space photometry
The Microvariability and Oscillations of STars (MOST) photometric satellite
has already undertaken more than 64 primary campaigns which include some
clusters and has obtained observations of >850 secondary stars of which ~180
are variable. More than half of the variables pulsate, with the majority being
of B-type. Since 2006 January, MOST has operated with only a single CCD for
both guiding and science. The resulting increase in read-out cadence has
improved precision for the brightest stars. The 2007 light curve for Procyon
confirms the lack of predicted p-modes with photometric amplitudes exceeding 8
ppm as we found in 2004 and 2005. p-modes have been detected in other
solar-type stars as well as pre-main sequence objects, roAp and delta Scuti
variables. g-modes have been detected in a range of slowly pulsating B stars,
Be stars and beta Cephei variables. Differential rotation has been defined for
several spotted solar-type stars and limits set to the albedo of certain
transiting planets and the presence of other perturbing planets. The mission is
expected to continue as long as the experiment operates.Comment: 9 pages, 7 figures, from HELAS-II meetin

Jean Cocteau: Orpheus Narcissus
Over the course of thirty years, the poet and filmmaker Jean Cocteau created a singular artistic project he called the Orphic trilogy: Le Sang dâun poĂšte (1930), OrphĂ©e (1950), and Le Testament dâOrphĂ©e (1959). This trilogy is marked by an Orphic pattern of a poetâs journey into an underworld to confront death. I will show that Cocteauâs invention is to have Orpheus be in love with death, for death to be an attractive and irresistible force to the poet. Simultaneously, Cocteau avails himself of the Narcissus myth, the man in love with his own reflection. Orpheus and Narcissus converge in these films as a synthesis of Cocteauâs personal obsessions, which I will identify in his own life. I will reveal that Cocteauâs usage of Narcissus results in a queer aesthetic which courses through the trilogy. Through a close textual and visual analysis of these films, I hope to enrich the appreciation and criticism of this major artistic achievement
