Using the Gamma-Ray Spectrometer on the Mars Odyssey, we have identified two regions near the poles that are enriched in hydrogen. The data indicate the presence of a subsurface layer enriched in hydrogen overlain by a hydrogen-poor layer. The thickness of the upper layer decreases with decreasing distance to the pole, ranging from a column density of about 150 grams per square centimeter at -4...
پدیده خوردگی در خطوط لوله انتقال گاز یکی از معضلات مهم جهان امروز بوده و خورندگی خاک یکی از اصلی¬ترین عوامل خوردگی در لوله¬های انتقال گاز می¬باشد. خاک خورنده می¬تواند در اثر عوامل شیمیایی و میکروبی موجب خوردگی در لوله شود و اثرات زیان بار شدیدی را به پروژه¬های انتقال گاز وارد نماید، لذا به منظور کاهش اثرات وارده به خطوط لوله، بایستی خورندگی خاک مورد ارزیابی قرار گیرد. این تحقیق در مورد خوردگی چ...
BACKGROUND Determining the age-specific hospitalization burden associated with seasonal influenza and the (H1N1) 2009 pandemic is important for the development of effective vaccine strategies and clinical management. The aim of this study was to investigate age-specific differences in hospitalization rates during the pandemic and seasonal periods. METHODS Using the Taiwan National Health Insu...
We report the observation of atomic-pair absorption in barium and in barium-thallium vapors using a white-light source. At atomic densities on the order of 10(17) atoms/cm(3) we measure absorptions of 2.9% cm(-1) for Ba-Ba and 2.3% cm(-1) for Ba-TI. In both cases, the absorption maxima occur at the predicted (R = infinity) wavelength and have a full width at half maximum of approximately 15 cm(...
We have carried out an autosomal genome scan for genes contributing to the development of type 2 diabetes and affecting BMI in the Japanese population (164 families, 256 affected sib-pairs). We found 12 regions that showed nominally significant multipoint evidence of linkage with type 2 diabetes (i.e. logarithm of odds [LOD] score >0.59, P < 0.05): chromosome 1 29.9 cM; chromosome 2 169.6 and 2...
Population densities of Belonolaimus longicaudatus, Pratylenchus brachyurus, and Trichodorus christiei were determined from soil samples taken weekly in Tifton, Georgia during a 14-month period (except for April and May) at 15-cm increments to a depth of 105 cm. Belonolaimus longicaudatus predominately inhabited the top 30 cm of soil that was 87-88% sand, 6-7% silt, and 5-7% clay. No specimens ...
Present-on-admission modifiers for International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes are rapidly becoming a standard coding requirement. Inaccurate coding of these modifiers can distort analyses of risk-adjusted outcomes and determinations of hospital reimbursement. A set of 12 screens for the plausibility of present-on-admission designat...
We observed Sgr A* using the Very Large Array (VLA) and the Giant Metrewave Radio Telescope (GMRT) at multiple cm and mm wavelengths on 17 June 2003. The measured flux densities of Sgr A*, together with those obtained from the Submillimeter Array (SMA) and the Keck II 10 m telescope on the same date, are used to construct a simultaneous spectrum of Sgr A* from 90 cm to 3.8 μm. The simultaneous ...
