The sickle is still an ultimate choice hand tool for harvesting the new variety of rice. This preference continues. The sickles used by Balinese harvester are usually nonserrated. The sharpness of nonserrated sickles is reduced quickly, so the harvester needs time to sharpen them frequently, which mean time loss and productivity reduction. To solve this problem, research has been conducted usin...

Naveen, Baibhav and Local sickles were evaluated for harvesting paddy crop with 20 farm women age 30-50 years (Subjects) at surrounding villages of KVK, Chatra, Jharkhand. The data of improved and Local sickles were compared. During the harvesting session, they spend nearly 7-8 hours daily to perform the activity. The Naveen sickle was the heaviest weight 229g followed by Baibhav and deshi was ...

This study focuses on the semiparametric efficient estimation of random effect panel models containing AR(1) disturbances. We also consider such estimators when the effects and regressors are correlated (Hausman and Taylor, 1981). We introduce two semiparametric efficient estimators that make minimal assumptions on the distribution of the random errors, effects, and the regressors and that prov...
