1. DESIGN AND EXPERIMENT OF SELF-PROPELLED SYSTEM FOR PADDY FIELD WEEDER BASED ON THE INTERACTION MECHANISM OF WHEEL-SOIL
ABSTRACT Aiming at the low mechanization of paddy field weeding and lack of dedicated agricultural machinery for paddy field weeding in China, a self-propelled system of paddy field weeding machine was designed. The overall structure and working principle of self-propelled system were illustrated and analyzed. The interaction mechanism of wheel-soil during w

2. Adaptation of the Pediatric Smell WheelTM to evaluate olfactory function in Brazilian children
Abstract Objective: Olfaction influences nutrition, safety, and the cognitive development of children. Presently there are few olfactory tests for children, and normative reference values are generally lacking. In this study, we validate the Pediatric Smell WheelTM (PSW) to evaluate olfactory function in Brazilian children. Methods: We modified and validat

3. Effect of titanium and nitrogen inoculation on the microstructure, mechanical properties and abrasive wear resistance of Hadfield Steels
Abstract The effect of titanium and nitrogen addition on Hadfield steels was investigated. In order to do this, two grades of steels were produced in terms of titanium and nitrogen addition. The final samples had their microstructure characterized and their mechanical properties were evaluated by uniaxial tensile and Charpy impact tests. Furthermore, the wea

5. DOES THE PRESENCE OF STRAW IN THE BILLET AFFECT THE QUALITY OF SUGARCANE PLANTING SYSTEMS?
ABSTRACT The mechanized harvesting process of sugarcane seedlings affects the mechanized planting operation in the sense that straw adhered to the billet can reduce the quantity of non-viable gems obtained as a result of mechanical damage sustained during the mechanized operation. This study proposes a method to improve the quality of the implantation of sug

8. Load equivalency factors for off-road trucks
Abstract This article addresses an analysis of the Load Equivalency Factor (LEF) for off-road trucks. A new LEF curve for single axles with dual wheels covering trucks from 6.0 to 151.42 tons per axle is proposed, converting various magnitudes of damage from wheel loads to damage caused by the standard axle load of 8.2 tons. Then, this damage ratio was raise
