We investigate a Mexican federal program that compensates landowners for forest protection. We use matched controls from the program applicant pool to establish counterfactual deforestation rates. Deforestation was reduced by 50% in enrolled parcels, but expected average clearing rates without the program were low (0.8% per year), suggesting modest total(More)
In an injected oscillator, synchronization bands (or Arnold tongues) are theoretically obtained at rational ratios between the frequencies of the generator and the self-oscillation. Here an in-depth analysis of this phenomenon is carried out. A simple and accurate technique is presented for the harmonic-balance prediction of the subharmonic and rational(More)
The structural and magnetic data of the trinuclear compound [Cu3(L)2(CH3COO)2(OH)2(dmf)2] (HL = N-(2-methylpyridyl)toluensulfonylamide) are reported. The compound crystallizes in the monoclinic system, space group P2(1)/n (no. 14), with a = 11.6482(6) A, b = 13.5772(6) A, c = 13.5306(7) A, alpha = 90 degrees, beta = 92.859(5) degrees, gamma = 90 degrees,(More)
New Cu(II) complexes of sulfamethazine (4-amino-N-[4,6-dimethyl-2-pyrimidinyl]benzenesulfonamide, HL) [Cu(2)(CH(3)COO)(2)(L)(2)].2dmf (1) and ([Cu(L)(2)].2H(2)O)(infinity) (2) were prepared and structurally characterized. Compound 1 crystallizes in the monoclinic system, space group P2(1)/n, with a = 8.9486(9) A, b = 15.0956(12) A, c = 16.542(3) A, beta =(More)
A simple geometrical method to measure the aberration of astigmatism present in the wavefront that emerges from a telescope is presented. The method is based on the analysis of the external contour of the image of a slightly defocused star. An expression elliptical edge is obtained, which links the rms value of Z22 to the geometric parameters of the(More)
In this study, we analyse the internal dynamics of star-forming H i i regions and their efficiency in interacting with the ambient interstellar medium. We have selected the nearby (4.5 Mpc) nearly face-on spiral galaxy M83, and from GHαFaS (Hernandez et al. 2008) Fabry-Perot observations of the central 3.4 × 3.4 region, extracted the integrated Hα(More)
