This paper investigates corruption in welfare targeting in developing countries and evaluates the effectiveness of top-down monitoring in addressing this issue. Using administrative records from China's rural Basic Living Allowance program (RBLA), we demonstrate that cadre-connected families are...

In this work, a semisolid back-extruded ZCuSn10P1 copper alloy sleeve was solution treated. The effects of solution temperature on the microstructures and mechanical properties were investigated. The results show that the solution and aging treatments have a great influence on the...

The thixotropic back-extruded tin bronze shaft sleeves were heat-treated at 630 °C, 660 °C, 690 °C and 720 °C for 1 h, respectively. The effect of solution temperature on the microstructure and mechanical properties of thixotropic back-extruded tin bronze shaft sleeve was studied by means of...
