The UVS instrument on the Juno mission recorded transient bright emission from a point source in Jupiter's atmosphere. spectrum shows that is consistent with 9600-K blackbody located 225 km above 1-bar level and duration of was between 17 ms 150 s. These characteristics are bolide Based energy emitted, we estimate impactor had mass 250-5000 kg, which corresponds to diameter 1-4 m. By considerin...

a study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of yazd. the average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20x mg/day. there is evidence which shows that more important factors than the amount of urinary calcium exist which influence ...

Space observations have shown that the highest concentrations of lightning on the Earth are mostly on the territory of the Democratic Republic of Congo (DR Congo). The global climatology of lightning activity proposed by Christian et al.1 and based on data recorded during five years (May 1995-March 2000) by the Optical Transient Detector (OTD) loaded on board the satellite MicroLab-1, highlight...

Interpretations of quantum theory have traditionally assumed a “Galilean” observer, a bare “point of view” implemented physically by a quantum system. This paper investigates the consequences of replacing such an informationally-impoverished observer with an observer that satisfies the requirements of classical automata theory, i.e., an observer that encodes sufficient prior information to iden...

mnemiopsis leidyi population activities first were recorded during the coastal observations in 2001 in which its population considerably increased afterward and now sustained the southern caspian sea. maximum summer-autumn m. leidyi abundance was recorded in euphotic layer in 2002 (851±85 ind.m-3) and maximum biomass was in 2001 with 48.1±14.4 g.m-3) while minimum were in aphotic layer. in year...

Modulated Langmuir waveforms have been observed by several spacecraft in various regions of the heliosphere, such as the solar wind, the electron foreshock, the magnetotail, or the auroral ionosphere. Many observations revealed the bursty nature of these waves, which appear to be highly modulated, localized, and clumped into spikes with peak amplitudes typically 3 orders of magnitude above the ...

Limited studies have been done on nematodes of Bellamya bengalensis (fresh water snails) in the world. Following, our clinical observations on eye disease in a fish ponds, which were contained Bellamaya bengallensis snails, present study was made to determine of nematodes fauna of Bellamya bengalensis and evaluation of their medical and veterinary importance in Khouzestan province. For this pur...

Abstract Concurrent hot extremes and droughts undoubtedly aggravate the impacts of on agriculture, natural environment, human society. Recent studies mainly focus trends changes in frequency severity compound drought extreme events. However, relatively little attention has been paid to mean temperature during conditions. In this study, we investigated observed projected periods across China a c...

Estimation procedures for nonstationary Markov chains appear to be relatively sparse. This work introduces empirical  Bayes estimators  for the transition probability  matrix of a finite nonstationary  Markov chain. The data are assumed to be of  a panel study type in which each data set consists of a sequence of observations on N>=2 independent and identically dis...
