Exospheric Temperature Measured by NASA-GOLD Under Low Solar Activity: Comparison With Other Data Sets.

Exospheric temperature is one of the key parameters in constructing thermospheric models and has been extensively studied with in situ observations and remote sensing. The Global-scale Observations of the Limb and Disk (GOLD) at a geosynchronous vantage point provides dayglow limb images for two longitude sectors, from which we can estimate the terrestrial exospheric temperature since 2018. In this paper, we investigate climatological behavior of the exospheric temperature measured by GOLD.

Cloud Formation From a Localized Water Release in the Upper Mesosphere: Indication of Rapid Cooling.

Polar mesospheric clouds (PMCs) occur in the summer near 82 -85km altitude due to seasonal changes of temperature and humidity. However, water vapor and associated PMCs have also been observed associated with rocket exhaust. The effects of this rocket exhaust on the temperature of the upper mesosphere are not well understood.

Retrieval of Lower Thermospheric Temperatures from O A Band Emission: The MIGHTI Experiment on ICON.

The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) is a satellite experiment scheduled to launch on NASA's Ionospheric Connection Explorer (ICON) in 2017. MIGHTI is designed to measure horizontal neutral winds and neutral temperatures in the terrestrial thermosphere. Temperatures will be inferred by imaging the molecular oxygen Atmospheric band (A band) on the limb in the lower thermosphere.

Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI): Instrument Design and Calibration.

The Michelson Interferometer for Global High-resolution imaging of the Thermosphere and Ionosphere (MIGHTI) instrument was built for launch and operation on the NASA Ionospheric Connection Explorer (ICON) mission. The instrument was designed to measure thermospheric horizontal wind velocity profiles and thermospheric temperature in altitude regions between 90km and 300km, during day and night. For the wind measurements it uses two perpendicular fields of view pointed at the Earth's limb, observing the Doppler shift of the atomic oxygen red and green lines at 630.

Lead and the deafness of Ludwig van Beethoven.

Objectives/hypothesis: To reexamine the cause of Beethoven's hearing loss because of significant recent articles.

Data Sources: Medical and musical literature online, in print, and personal communication.

Methods: Relevant literature review.

Pain reduction by fibrin sealant in older children and adult tonsillectomy.

Objectives: Because tonsillectomy is a painful procedure in adults, this study was performed to see whether the addition of fibrin sealant (Tisseel) to the tonsillar fossa at the completion of tonsillectomy would reduce pain in adults and allow them to return to work sooner.

Study Design: Forty adult patients over the age of 12 were entered into a prospective randomized study to see whether the addition of fibrin sealant (Tisseel) to the tonsillar fossa at the completion of tonsillectomy for recurrent tonsillitis would reduce the time the patient needed to take narcotic analgesics after surgery.

Methods: Fifteen adults had a traditional complete tonsillectomy by means of a needle point Bovie and served as a control group.
