Evolution over two decades of the tropical
18 The interannual variability of cloud properties in a tropical subsidence area (South 19 Atlantic Ocean) is examined using 23 years of ISCCP cloud fractions and optical depths, 20 complemented with ISCCP/Meteosat visible reflectance and a four-years comparison with 21 CALIPSO-GOCCP products. The mean seasonal cloud properties are examined in the area, as 22 their interannual evolution. Circul...
متن کاملEmergence of variant avian infectious bronchitis virus in India
Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...
متن کاملChanges in Earth's reflectance over the past two decades.
We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud properties to construct from the latter a proxy measure of Earth's global shortwave reflectance. This proxy shows a steady decrease in Earth's reflectance from 1984 to 2000, with a strong climatologically significant drop after 1995. From ...
متن کاملChildhood leprosy in India over the past two decades.
OBJECTIVES Clinico-epidemiological pattern of childhood leprosy in India over the past two decades were analysed from the Indian studies conducted during the years 1990-2009. RESULTS Twelve studies on childhood leprosy were included. Ten were conducted in health institutions and one was a community-based survey. Voluntary reporting was the principal method of case detection; community survey ...
متن کاملVirulent Avian Infectious Bronchitis Virus, People’s Republic of China
A virulent avian infectious bronchitis virus (IBV) was isolated from 30-day-old broiler chickens that exhibited respiratory symptoms, nephropathologic lesions, and a high proportion of deaths in the People's Republic of China during 2005. The strain, designated YN, was genetically and pathologically characterized. Phylogenetic analysis showed that YN and most of the previously characterized IBV...
