Immunofluorescent studies were made on chicken kidney cell cultures infected with various temperature-sensitive (ts) mutants of an avian adenovirus, chicken embryo lethal orphan (CELO), which grow well at the nonrestrictive temperature of 31 degrees , but fail to grow at the restrictive temperature of 40 degrees . At 40 degrees some mutants (ts 5, 8, and 10) accumulated viral antigen in the cyt...

A moderately deep survey of stellar maser sources toward the Galactic center has been made in the SiO J=1-0 v=1 and v=2 transitions (∼ 43 GHz) with the Nobeyama 45-m telescope of a beam size of about 40. At the Galactic center (Sgr A*), 7 (4 new) SiO maser sources were detected in one beam. In order to investigate the spatial distribution of SiO maser sources, we have also observed the offset p...

Abstract Reanalyzing Cassini radio observations performed during Jupiter's flyby of 2000–2001, we study the internal (rotational) versus external (solar wind) control emissions, from kilometer to decameter wavelengths, and relations between different auroral components. For that purpose, build a database occurrence Jovian components bKOM, HOM, DAM observed by Cassini, then frequency‐longitude s...

A field experiment was conducted during rabi season (November to February, 2020–21) at College Farm, of Agriculture, Rajendranagar, Hyderabad. The farm is geographically positioned 17°19’16.4” North latitude and 78°24’43” East longitude an altitude 542.3 m above the mean sea level. According troll’s climatic classification, it categorized under semi-arid tropics (SAT). experimental sandy loam t...

In this letter, we study the temporal and spatial variability of ionospheric irregularities by generating high-resolution maps observed amplitude scintillation index (S4) using data from a multi-constellation multi-frequency GNSS receiver. The is located in Arabian Peninsula region, which falls under northern crest equatorial ionization anomaly (EIA). Even though was conducted during solar mini...
