A comparative study to evaluate the efficacy of applying ice packs versus applying manual pressure on discomfort at the pentavalent vaccination site among newborns who were attending the immunization clinic at a selected hospital in Coimbatore.

Abstract

A field experiment was conducted in Karbala Governorate/Tawrij District in 2024 on a silty clay soil to investigate the role of the chisel plow in loosening the hardpan layer and promoting crop growth. A New Holland TD80 tractor was used in this experiment. Two components were examined: operating speed (2.80, 4.65, and 6.15 km/h-1), and plowing depth (50 and 65 cm).  Mechanical unit technical metrics such drawing force, slippage percentage, fuel usage, and maize plant output were examined.  The experiment used a three-replicate Randomized Complete Block Design (RCBD).  The lowest slippage percentage was 6.90% and the lowest traction force was 618.11 kg at 2.80 km/h-1.  The lowest fuel usage was 9.99 L/ha and the maximum plant output was 8.05 t/ha at 6.15 km/h-1.  A 50 cm plowing depth yielded the lowest pulling force (613.21 kg), slippage (7.57%), and fuel usage (11.91 L/ha).  The maximum plant output was 6.76 t/ha at 65 cm.  All attributes were significantly affected by the speed-plowing plot interaction.  Operating speed, traction force, plant productivity, slippage, Chisel Plow.
