Printed Planar 8 x 8 Array Antenna With Circular Polarization for Millimeter-Wave Application
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2012)
A new type of printed millimeter planar antenna with circular polarization for 60-GHz range is proposed. Radiation elements with two open tape rings are arranged in a two-dimensional 8 x 8 antenna array. Feeding is synphase ...
A novel C,D-spirolactone analogue of paclitaxel: autophagy instead of apoptosis as a previously unknown mechanism of cytotoxic action for taxoids
(Royal Soc Chemistry, Cambridge, 2012)
The design, synthesis and biological evaluation of a novel C, D-spirolactone analogue of paclitaxel is described. This is the first paclitaxel analogue without an oxetane D-ring that shows a significant cytotoxic effect ...
Maskless convex corner compensation technique on a (100) silicon substrate in a 25 wt% TMAH water solution
(Iop Publishing Ltd, Bristol, 2012)
A maskless convex corner compensation technique in a 25 wt% TMAH water solution at the temperature of 80 degrees C is presented and analyzed. The maskless convex corner compensation technique is defined as a combination ...
CH/pi interactions in metal-porphyrin complexes with pyrrole and chelate rings as hydrogen acceptors
(Elsevier Science Inc, New York, 2012)
CH/pi interactions in metal porphyrinato complexes were studied by analyzing data in crystal structures from the Cambridge Structural Database (CSD) and by quantum chemical calculations. The analysis of the data in the CSD ...
Extension of the AMBER force field to cyclic alpha,alpha dialkylated peptides
(Royal Soc Chemistry, Cambridge, 2012)
The popular biomolecular AMBER (ff99SB) force field (FF) has been extended with new parameters for the simulations of peptides containing alpha, alpha dialkylated residues with cyclic side chains. Together with the recent ...
Bench-to-bedside review: Neonatal sepsis - redox processes in pathogenesis
(Biomed Central Ltd, London, 2012)
The present review is aimed at elucidating the neonatal 'sepsis redox cycle' - the cascade of inflammatory and redox events involved in the pathogenesis of sepsis in neonates. While adult and neonatal sepses share some ...
Size-segregated mass concentration and water soluble inorganic ions in an urban aerosol of the Central Balkans (Belgrade)
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The distribution of nano/micron inorganic main ions in the size-segregated urban aerosol of Belgrade center was studied during the summer-autumn of 2008. The particle size distribution in the size ranges D(p) LT = 0.49 ...
Crystal structure and conformational analysis of s-cis-(acetylacetonato)(ethylenediamine-N,N '-diacetato)-chromium(III)
(Springer, New York, 2012)
The crystal structure of [Cr(edda)(acac)] (edda = ethylediamine-N,N'-diacetate; acac = acetylacetonato) has been determined by a single crystal X-ray diffraction study at 150 K. The chromium ion is in a distorted octahedral ...
Toward enhanced hydrogen production in a catalytic naphtha reforming process
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is ...
Analysis of dynamic mechanical, thermal and surface properties of poly(urethane-ester-siloxane) networks based on hyperbranched polyester
(Elsevier, 2012)
Six polyurethane networks were synthesized from Boltorn (R) hyperbranched polyester of the second pseudo generation, alpha,omega-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and ...
