The nonlinear optical properties of pepper oil are studied by diffraction ring patterns and Z-scan techniques with continuous wave beam from solid state laser at 473 nm wavelength. The nonlinear refractive index of the sample is calculated by both techniques. The sample show high nonlinear refractive index. Based on Fresnel-Kirchhoff diffraction integral, the far-field intensity distributions of ring patterns have been calculated. It is found that the experimental results are in good agreement with the theoretical results. Also the optical limiting property of pepper oil is reported. The results obtained in this study prove that the pepper oil has applications in nonlinear optical devices.

This paper is an empirical analysis to explore the relationships between urban conflict and both rent seeking and corruption. It examines social disturbances in medieval France through a sample of twelve towns examined over the period 1270-1399 in a real context of informational asymmetries, commitment problems, and issues indivisibilities. As regards the economic corruption class, it is found that townspeople rebel more often and more intensely against the extortion of funds carried out by policy makers than against the embezzlement of a part of these funds. As to the political corruption class, the findings highlight that abuse of power against municipalities is identified in more social unrest than influence peddling against these local institutions. Furthermore, it is shown that rent-seeking-related policies (like arbitrary actions limiting property rights, economic rules-based policies, and targeted political measures) have less influence on urban conflict than corrupt policies do. These findings produce insights that apply beyond the historical context and analysis of the paper. Situations presenting over-indebted towns despite overtaxed people disturb also modern democracies.
