Abstract Nitrous oxide (N 2 O) is a long-lived greenhouse gas with a large radiation intensity and it is emitted mainly from agricultural land. Accurate estimates of total direct N 2 O emissions from croplands on a count...

In an epidemiologic study of mortality at the Portsmouth Naval Shipyard (PNS), the National Institute for Occupational Safety and Health (NIOSH) found no evidence of excess deaths due to leukemia or other cancers among workers exposed to low levels of ionizing radiation [1]. In a subsequent analysis, Bross and Driscoll [2] identified excess lung cancer mortality in PNS workers with lifetime rad...

influence of maternal and sire-generation interaction effects on day-old chick' weight was investigated in two commercial broiler sire and dam lines, and in mazandaran native fowls. the data were analysed through restricted maximum likelihood (reml) procedures, using asreml software. ten different animal models were implemented and compared with likelihood ratio test. all models consisted ...

the objective of this study was to estimate variance components and genetic parameters for growth curve parameters in shall sheep. studied traits were parameters of brody growth model which included a (asymptotic mature weight), b (initial animal weight) and k (maturation rate). the data set and pedigree information used in this study were obtained from the animal breeding center of iran and co...

Abstract A lower bound on the uncertainty in observational estimates of aerosol direct radiative effect (DRE; interaction with solar radiation by all aerosols) and forcing [DRF; just anthropogenic aerosols (RF ari )] is quantified making optimistic assumption that global observations can be made accuracy found Aerosol Robotic Network (AERONET) sun photometer retrievals. The global-mean all-sky ...
