The evolution of the Earth’s atmosphere is essentially the story of atmospheric oxygen. Virtually every realm of the Earth sciences–biology, geology, geochemistry, oceanography and atmospheric science–is needed to piece together an understanding of the history of oxygen. Over the past decade, new data from these fields has shown that there were two significant increases in atmospheric O2 levels...

The analytic solution of a satellite orbit disturbed by the atmospheric drag is derived in this paper. The disturbing force vector is first transformed and rotated to the orbital frame so that it can be used in the simplified Gaussian equations of satellite motion. Then the force vector is expanded to triangle functions of the Keplerian angular elements and the disturbances are separated into t...

PATIENT Female, 60 FINAL DIAGNOSIS: Recurrent incisional hernia Symptoms: - MEDICATION - Clinical Procedure: Limited ileo-cecal resection Specialty: Surgery. OBJECTIVE Diagnostic/therapeutic accidents. BACKGROUND Iatrogenic entero-atmospheric fistula is devastating and its management is extremely difficult because it is often associated with fluid and electrolyte disturbances, nutritional...

introduction: sleep disorders can influence either directly or indirectly, on the family, colleagues and finally the community. in the realm of children, the most serious complications of sleep is anxiety and behavioral problems that make them prone to academic failure, family tensions and psychosocial – social trauma. concerning the significance, outbreak of sleep disorders and its complicatio...

sleep disturbance, known as insomnia, is a common symptom of many mental illnesses. insomnia is one of the most prevalent sleep disorders characterized by sleep difficulty that affects our life and work safety. several lines of evidence support the primary insomnia as a risk factor/predictor for depression and anxiety disturbances. anxiety disorders and insomnia are common, debilitating and hig...

s of papers in press: 1. Phase Height Pluctuutions in the Ionosphere beiweon 130 and 250 km, I. Toli'.toy and II. Montes Journal of Terrestrial and Atmospheric Physics, 1971. Power spectra of CW phase-path sounders operating at 6.0, 4.8 and 2.4 MHz often display peak or slope changes at periods in the 5-20 minute range. Plots of these periods vs. real height tend to follow mean VUisälä frequenc...

In the paper, we discuss results of processing and analysis field data obtained from a laser-based supersensitive detector during registering hydrosphere pressure variations on seabed at various points Sea Japan shelf. The main focus is study physical mechanisms occurrence nonlinear hydrophysical disturbances in range gravity infragravity sea waves classed as rogue waves, amplitudes which are m...

Total electron content measurements by using dual-frequency signals of global navigation satellite systems (GNSS) makes it possible to obtain the distribution density ionosphere with high spatial and temporal resolution. Such resolution allows explore small-scale traveling ionospheric disturbances generated terrestrial geophysical events, including seismic activity, solar terminator passage, at...

Abstract Undisturbed trade-wind conditions comprise the most prevalent synoptic weather pattern in Hawai’i and produces a distinct of orographic rainfall. Significant total rainfall contributions extreme events are linked to four types atmospheric disturbances: cold fronts, Kona lows, upper-tropospheric disturbances, tropical cyclones. In this study, 20- year (1990-2010) categorical disturbance...
