Bilindiği üzere metalik malzemeler için korozyon hayati hasar türlerinden biridir. Yapılan araştırmalarda korozyonun ülkelere olan maliyetinin gayri safi milli hasılanın (GSMH) %3,5-4’ ü kadar olduğu belirlenmiştir. Bu sebeple üstesinden gelmek çok çeşitli yöntemlere başvurulmaktadır. Bunlar başlangıçta tasarım yani malzeme-ortam uyumunu temin etmek, inhibitör kullanmak, kaplamalar yapmak ve ku...
The measurement of the physical extent of opening of the upper esophageal sphincter (UES) during bolus swallowing has to date relied on videofluoroscopy. Theoretically luminal impedance measured during bolus flow should be influenced by luminal diameter. In this study, we measured the UES nadir impedance (lowest value of impedance) during bolus swallowing and assessed it as a potential correlat...
The future German Environmental Mapping and Analysis Program (EnMAP) mission, due to launch in late 2019, will deliver high resolution hyperspectral data from space and will thus contribute to a better monitoring of the dynamic surface of the earth. Exploiting the satellite’s ±30◦ across-track pointing capabilities will allow for the collection of hyperspectral time-series of homogeneous qualit...
BACKGROUND Progestins as respiratory stimulants in chronic obstructive pulmonary disease (COPD) have been investigated in males and during wakefulness. However, sleep and gender may influence therapeutic responses. We investigated the effects of a 2-week medroxyprogesterone acetate (MPA) therapy on sleep and nocturnal breathing in postmenopausal women. METHODS A single-blind placebo-controlle...
PURPOSE The "PSA nadir + 2 rule," defined as any rise of 2 ng/ml above the current prostate-specific antigen (PSA) nadir, has replaced the American Society for Therapeutic Radiology and Oncology (ASTRO) rule, defined as three consecutive PSA rises, to indicate biochemical failure (BF) after radiotherapy in patients treated for prostate cancer. We propose an original approach to evaluate BF rule...
[1] The fundamental measurement of the Tropospheric Emission Spectrometer (TES) on board the Aura spacecraft is upwelling infrared spectral radiances. Accurate TES retrievals of surface and atmospheric parameters such as trace gas amounts critically depend on well-calibrated radiance spectra. On-orbit TES nadir observations were evaluated using carefully selected, nearly coincident spectral rad...
