It is tempting to consider Girard Desagues’ mathematical work, more precisely his Brouillon project on conics, as a work of mathematics applied perspective. We would like show in this text that it probably pertinent Desargues does practitionner the art shall analyse few extracts Desargues’ with point view mind so shed light innovative ideas could be hard understand sometimes obscure style. how ...

Title of dissertation: SELECTION OF STAR CEOS AND ITS IMPLICATIONS ON FIRM PERFORMANCE AND CEO COMPENSATION Minwen Li, Doctor of Philosophy, 2010 Dissertation directed by: Professor Vojislav Maksimovic, Dean's Chair Professor of Finance, Department of Finance My dissertation examines a board’s decision to hire a star CEO and the implication of such decision on the new CEO compensation and firm ...

[1] In this case, an artist and the organization that hired him to produce a sculpture contest the ownership of the copyright in that work. To resolve this dispute, we must construe the "work made for hire" provisions of the Copyright Act of 1976 (Act or 1976 Act), 17 U.S.C. §§ 101 and 201(b), and in particular, the provision in § 101, which defines as a "work made for hire" a "work prepared by...

Neurology 2012;78:688–689 The Food and Drug Administration (FDA) recently approved [I]ioflupane ([I]-fluoropropyl CIT), a dopamine transporter (DAT) radioligand, for SPECT to “assist in the evaluation of adult patients with suspected parkinsonian syndromes (PS).”1 This permits physicians to prescribe [I]ioflupane SPECT scans as part of clinical practice. Advertisements encourage clinicians to o...

UNLABELLED Myocardial perfusion imaging with SPECT (SPECT-MPI) and 64-slice CT angiography (CTA) are both established techniques for the noninvasive evaluation of coronary artery disease (CAD). Three-dimensional (3D) SPECT/CT image fusion may offer an incremental diagnostic value by integrating both sets of information. We report our first clinical experiences with fused 3D SPECT/CT in CAD pati...

OBJECTIVES The coronary artery calcium (CAC) score has been shown to predict future cardiac events. However the extent to which the added value of a CAC score to the diagnostic performance of myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT) is unclear. The purpose of this study is to investigate the correlation between CAC score and SPECT in patients with...

The effect of motor carrier deregulation on the employment and earnings of truck drivers is examined, using data for the period 1973-95. The use of a quasi-experimental design is made possible through the comparison of wages before and after deregulation among drivers in the previously regulated for-hire sector, drivers in unregulated private carriage, and an economy-wide group of male non-driv...

SPECT has traditionally been regarded as nonquantitative. Advances in multimodality γ-cameras (SPECT/CT), algorithms for image reconstruction, and sophisticated compensation techniques to correct for photon attenuation and scattering have, however, now made quantitative SPECT viable in a manner similar to quantitative PET (i.e., kBq cm(-3), standardized uptake value). This review examines the e...
