This was followed in by the acquisition of the bankrupt American company Learjet , a manufacturer of business jets headquartered in Wichita, Kansas ; and finally the money-losing Boeing subsidiary, de Havilland Aircraft of Canada based in Toronto , Ontario in It also manufactured the Bombardier amphibious water-bomber in Dorval and North Bay , and the Global Express and the Challenger lines of business jets. The launch customer for the CSeries, Lufthansa , signed a letter of intent for up to 60 aircraft and 30 options in The intention was to break the near- duopoly of Airbus and Boeing. On 30 September it broke ground on its permanent facility, due to open late In April , Canada's Porter Airlines placed a conditional order for 12 CSeries aircraft, with options for another Studies underway included an environmental assessment, master planning exercise and preliminary runway design. In January , Bombardier Inc. President Guy Hachey retired and Bombardier Aerospace was split into three divisions: business aircraft; commercial aircraft and aerostructures; and engineering services. As part of the corporate overhaul, 1, jobs were cut.

Mishke, Dr. Howard N. Contents at a Glance 1. Standard Atmosphere It is arguably the most comprehensive book on aircraft stress analysis ever written. While some of the methods are more than fifty years old, the lessons are timeless. This book is a compilation of the mistakes, omissions and typographical errors my teammates and I have discovered in the last two decades. Note the slide rule disclaimer on page A The book could easily be expanded to fill a five volume set.

NTRS integrates three separate information collections and enables search and retrieval of information through a common interface: NACA Collection: NASA Collection: Citations and documents created or sponsored by NASA.

Thus, comparison of the NMR signal intensities of compounds in the absence or presence of a protein provides valuable information on the binding properties of a compound to the target protein. B , whereas no signal broadening was observed following incubation with other proteins such as TSLPR and carbonic anhydrase Fig.

The signal broadening effects of 1 by hTSLP were dose-dependent. The Kd value of compound 1 was The line was determined using weighted linear least-squares fit. HDX-MS monitors the exchange between deuterium in the solvent and backbone amide hydrogen, which generally provides information on the binding of a compound to a protein 24 , Deuterium uptake profiles are color-coded onto the modeled structure of hTSLP. Regions showing lower and constant deuterium uptake after binding of 1 are colored blue and grey, respectively, whereas hTSLPR is indicated in green.

B Deuterium uptake level plot of the blue-colored region. The expanded spectra for the amide signals of the residues Tyr 43, Leu 44, Asn , and Arg were presented. Compound 1 is shown as a stick model in cyan color. The key residues of hTSLP interacting with compound 1 were denoted. Surface electrostatic potentials are shown in blue and red color for positive and negative charges, respectively. Full size image Furthermore, we analyzed the binding mode of 1 on the surface of hTSLP using molecular docking simulations.

Computer-aided binding analysis of 1 and hTSLP revealed that 1 was bound to the positively charged pocket Lys 49 and Arg through its hydroxyl groups, and the B ring of 1 interacted with the hydrophobic residues including Tyr 43 and Leu 44 Fig.

Western blot Fig. On day 11 after the first challenge, the mice were euthanized and analyzed for eosinophilic inflammation. Since this model relies on the function of Th2 cells, we measured the number of allergen-specific T cells, which interestingly was not changed by compound 1 treatment Fig.

Figure 5 A Experimental design. On day 11 post allergen challenge, BAL was performed to determine eosinophilic inflammation.
