This paper investigates self-selection of returnees migrants in Brazil, Pouch from 2001 to 2010.We find evidence of the impact of inequality on selfselection through two opposing channels.First, migrations costs prevent low-skilled individuals from emigrating, which support positive selection.This selection is accentuated in locations with high ine
A field experiment was conducted at Ranchi (Jharkhand) during rabi season of 2009-10 to 2011-12 with wheat cultivar K 9107 sown on three dates (Nov 20,Dec 5 and Dec 20) to calibrate and validate the CERES-wheat model.There was a good agreement between simulated and observed wheat yields, days to anthesis and days to maturity.The validated model was
Abstract Introduction Open Online Courses (OOCs) are increasingly presented as a possible solution to the many challenges of higher education.However, there is currently little evidence available to support decisions around the use of OOCs in health professions education.The aim of this systematic review was to summarise the available evidence desc
This article presents an 11-level operation of the WE (Wee)-Type inverter.The topology employs a single DC-source, has a reduced number of components, and exhibits a boosting capability.A voltage balancing algorithm is proposed where the inverter’s redundant states are employed Shorts to maintain the auxiliary DC-link voltage.It is shown tha
Airborne wind energy systems (AWESs) represent a novel idea that aims to gather energy from Pattern Art stronger winds aloft while operating at altitudes above conventional wind turbines (WTs).For this study, we examined the wind resources at a height of 100 m available for traditional wind turbines with aerial wind energy technologies, in addition
