A new method for the preparation of anhydrous ethyl ester of lactic acid was studied.The selected method is based on catalytic transesterification of lactic acid oligomers, which were prepared for this purpose by autocatalytic oligomerization of lactic acid.In this work, a kinetic model for the case of catalytic alcoholysis of oligoesters was deriv
Abstract Effective urban planning and management rely on accurate land cover mapping, which can be achieved through the combination of remote sensing data and machine learning algorithms.This study aimed to explore and demonstrate the potential benefits of integrating Sentinel-1 SAR and Sentinel-2 MSI satellite imagery for urban land cover classifi
BackgroundPediculosis caused by head lice (Pediculus humanus capitis) infestation is still an important health problem in schoolchildren, especially girls, worldwide, including in Thailand.Although pediculicidal agents effectively kill head lice, the re-infestation rate is still high.Thus, prevention is an important strategy for any sustainable con
In this work, the kinematics of a spherical parallel manipulator composed of three peripheral limbs equipped with linear actuators and a passive center shaft is approached by means of the theory of screws.The displacement moondrop quarks analysis is carried out solving closure equations, which are obtained upon simple linear combinations of the com
