We present and compare in this paper new photometric redshift catalogs of the galaxies in three public fields: the NTT Deep Field, the HDF–N and the HDF–S. In the case of the NTT Deep Field, we present here a new photometric catalog, obtained by combining the existing BVrI and JKs with new deep U observations acquired with NTT-SUSI2, and which includes also(More)
The effects of a long term partial food restriction were studied in chickens and rats. In chickens the treatment resulted in increased plasma T4 levels while T4 levels in rats remained unchanged. Plasma T3 decreased in both species. In vitro hepatic outer ring deiodinating type I (ORD-I) activity was not influenced by the food restriction, suggesting that(More)
The effect of orally administered beta-glucans in protecting pigs against an ETEC infection after weaning was analysed in this study. Three beta-glucans that differed in origin (Saccharomyces cerevisiae (MCG (Macrogard) and G2) or Sclerotium rolfsii (G3)) and/or extraction procedure were tested. Pigs fed for 2 weeks after weaning with these glucans were(More)
Natural tocopherols (TC), rosemary (RO), green tea (GT), grape seed, and tomato extracts were supplemented in single and in combinations at total concentrations of 100 and 200 mg.kg(-1) of feed in a 4% linseed oil-containing diet to investigate the oxidative stability of broiler breast muscle. Supplementation with 300 mg.kg(-)1 of synthetic antioxidants(More)
zCOSMOS is a large-redshift survey that is being undertaken in the COSMOS field using 600 hr of observation with the VIMOS spectrograph on the 8mVLT. The survey is designed to characterize the environments of COSMOS galaxies from the 100 kpc scales of galaxy groups up to the 100 Mpc scale of the cosmic web and to produce diagnostic information on galaxies(More)
The evolution of galaxy clustering from z = 0 to z ≃ 4.5 is analyzed using the angular correlation function and the photometric redshift distribution of galaxies brighter than IAB ≤ 28.5 in the Hubble Deep Field North. The reliability of the photometric redshift estimates is discussed on the basis of the available spectroscopic redshifts, comparing(More)
We present an analysis of the evolution of galaxy clustering in the redshift interval 0 ≤ z ≤ 4.5 in the HDF-South. The HST optical data are combined with infrared ISAAC/VLT observations, and photometric redshifts are used for all the galaxies brighter than IAB ≤ 27.5. The clustering signal is obtained in different redshift bins using two different(More)
This paper presents new five passbands (UBV RI) optical wide-field imaging data accumulated as part of the DEEP Public Survey (DPS) carried out as a public survey by the ESO Imaging Survey (EIS) project. Out of the 3 square degrees originally proposed, the survey covers 2.75 square degrees, in at least one band ( normally R), and 1.00 square degrees in five(More)

Context. Photometric redshifts (photo-z’s) have become an essential tool in extragalactic astronomy. Many current and upcoming observing programmes require great accuracy of photo-z’s to reach their scientific goals. Aims. Here we introduce PHAT, the PHoto-z Accuracy Testing programme, an international initiative to test and compare different methods of(More)
