Most doubtful, though, is Gruchy's unbridled faith in planning. The unpredictable dynamics Gruchy finds in economic systems argue strongly against centralized planning, as neo- Austrians suggest. At the practical level ...

Ambient sampling for the Pittsburgh Air Quality Study (PAQS) was conducted from July 2001 to September 2002. The study was designed (1) to characterize particulate matter (PM) by examination of size, surface area, and ...

We use a novel research design to empirically detect the effect of social interactions among neighbors on labor market outcomes. Specifically, using Census data that characterize residential and employment locations down ...

Background: Denitrification is an important ecosystem service that removes nitrogen (N) from N-polluted watersheds, buffering soil, stream, and river water quality from excess N by returning N to the atmosphere before it ...

This study involves two aspects of our investigations of plasmonics-active systems: (i) theoretical and simulation studies and (ii) experimental fabrication of plasmonics-active nanostructures. Two types of nanostructures ...

A 1 : 1 mixture of (dppf)PtCl2 and AgOTf (5 mol%) catalyzed the intermolecular hydroamination of monosubstituted allenes with secondary alkylamines at 80 degrees C to form allylic amines in good yield with selective formation ...

Proton recoil polarization was measured in the quasielastic He-4((e) over right arrow, e '(p) over right arrow)H-3 reaction at Q(2) = 0.8 and 1.3 (GeV/c)(2) with unprecedented precision. The polarization-transfer coefficients ...
