  1. In continuation of our work on Wanzlick/Arduengo carbenes containing redox-active ferrocenyl substituents we report on the synthesis of N,N‘-diferrocenyl imidazol(in)ium salts as precursors of imidazol(in)-2-ylidenes. The necessary starting material…
  2. The ##IMG## [http://ej.iop.org/images/0022-3727/37/14/005/jphysd175138in003.gif] {{\rm N}_{2}^{ +\n }({\rm B}\,^{2}\Sigma _{\rm u}^{ + }-{\rm X}\,^{2}\Sigma _{\rm g}^{ + })} and ##IMG##\n…
  3. This paper combines the world's protected areas (PAs) under the Convention on Biological Diversity (CBD), common classification systems of ecosystem conservation status, and current knowledge on ecosystem responses to nitrogen (N) deposition to…
  4. The present article is designed to review literature providing evidence of the neural mechanisms mediating the individual expertise both in mental and motor imagery. Providing physiological recordings that correlate to the imagery experience is now…
  5. We measured the 15N natural abundance values of 320 individuals belonging to 45 different plant species of the Brazilian cerrado. We also determined delta15N of soil nitrogen as a function of soil depth. Our purpose was to test the hypothesis that…
  6. The capacity of nitrifying biomass, grown in biofilms or in suspension, to reduce NO(2) (-) and NO(3) (-) under anoxic conditions was tested in batch experiments. The estimated reduction rates were 5 and 25 mg N per gram volatile suspended solids…
  7. Nitrite has been commonly recognized as an important factor causing N(2)O production, which weakened the advantages of nitrogen removal via nitrite. To reduce and control N(2)O production from wastewater treatment plants, both long-term and batch…
  8. The reaction of N(2)O(5) on sea salt aerosol is a sink for atmospheric nitrogen oxides and a source of the Cl radical. We present room-temperature measurements of the N(2)O(5) loss rate on submicron artificial seawater (ASW) aerosol, performed with…
  9. Additives that exhibit polyelectrolyte behavior such as N,N-dimethylformamide (DMF) may improve the electrospinning characteristics of viscoelastic polymer solutions. DMF additions to the solution lead to extensive jet splaying, thereby reducing the…
  10. The structure of a stable recombinant ectodomain of influenza hemagglutinin HA(2) subunit, EHA(2) (23-185), defined by proteolysis studies of the intact bacterial-expressed ectodomain, was determined to 1.9-A resolution by using x-ray…
  11. Bone morphogenetic protein-2 (BMP-2) stimulates the differentiation of osteoblastic cells. However, the mechanisms involved in this effect are not well characterized. In this study, we determined the role of the cell-cell adhesion molecules…
  12. We report the structural and electrical characterization of thin films of organic semiconductor molecules consisting of an oligothiophene core capped with electron-withdrawing tricyanovinyl (TCV) groups. X-ray diffraction and atomic force microscopy…
  13. The relationship between extracellular Ca2+ concentration and EPSC amplitude was investigated at excitatory autapses on cultured hippocampal neurons. This relationship was steeply nonlinear, implicating the cooperative involvement of several Ca2+…
