The article discusses the publication activity of scientists in the field of studying the consequences of US economic sanctions against Iran, and their impact on the development of science and the economy in this countries. The paper considers the dynamics of publication activity in the field of biomedicine of Iranian scientists over the past 20 years. Increased sanctions have led to a shortage...

In August of 1997, The US National Automated Highway System Consortium (NAHSC) presented a proof of technical feasibility demonstration of automated driving. The 97 Demo took place on car-pool lanes on I15 in San Diego, California. Members of the Consortium demonstrated many different functions, including: Vision-based road following Lane departure warning Magnetic nail following Radar reflecti...

Pure and Er-doped Er crystal 2.4 1020 cm−3 , NaBi WO4 2 (NBW), NaBi MoO4 2, and LiBi MoO4 2 crystals have been grown by the Czochralski method. The three crystal hosts have similar structural and optical properties. The noncentrosymmetric space group I4̄ (No. 82) crystallographic structure has been established through 300 K single-crystal x-ray and neutron (for NBW only) diffraction. Er3+ energy...

Breakdown of ethylene glycol dinitrate (EGDN) in blood in vitro results in the liberation of inorganic nitrite and ethylene glycol mononitrate (EGMN). The nitrite is oxidized to inorganic nitrate but the EGMN is more resistant to further degradation. Similar metabolites are produced during the metabolism ofEGDN in vivo. The nitrate is excreted in the urine and accounts for 6o% of the injection....

Health and Health Behaviors during the Worst of Times: Evidence from the Great Recession While previous studies have shown that recessions are associated with better health outcomes and behaviors, the focus of these studies has been on the relatively milder recessions of the late 20th century. In this paper, we examine if the previously established counter-cyclical pattern in health and heath b...

Microbial colonization of soil-incorporated, C-labeled, crimson clover and ryegrass straw residues was followed under western Oregon field conditions from late summer (September) to the following early summer (mid-June) by measuring the C content of phospholipid fatty acid (PLFA) extracted from residues recovered from soil. Residue type influenced the rate of appearance of specific PLFA during ...

The complex of xylan and iodine and its formation in a solution of xylan, CaCl2, and I2+KI was investigated by UV/Vis, second-derivative UV/Vis, and Raman spectroscopy. The complex forms only at very high concentrations of CaCl2, suggesting that when the water available in the solution is not sufficient to fully hydrate the calcium cation the chelation with the hydroxyl groups of the xylan can ...

In light of the shortage of healthcare professionals, many developing countries operate a de facto two-tiered system of healthcare provision, in which Community Health Workers (CHWs) supplement service provision by fully qualified physicians. CHWs are relatively inexpensive to train but can treat only a limited range of medical conditions. This paper explicitly models a two-tiered structure of ...

Gary W. Burdick, John B. Gruber, Kelly L. Nash, Sreerenjini Chandra, and Dhiraj K. Sardar Department of Physics, Andrews University, Berrien Springs, MI Department of Physics and Astronomy, The University of Texas at San Antonio, San Antonio, TX ABSTRACT Absorption and fluorescence spectra obtained at temperatures as low as 4K were investigated between 200 and 1550 nm on samples containing appr...
