Crop protection is mostly carried out spraying active chemical agents with potential impact on the health of environment, operator and consumer. Recently the European Commission played an important role in the protection of the operator with respect to the pesticide contamination during spray application. An active protection offered by tractor cab is a new requirement when the machine is used ...
Improved human-tractor interface designs, such as well-accommodated operator enclosures (i.e. cabs and protection frames) can enhance operator productivity, comfort and safety. This study investigated farm-worker anthropometry and determined the critical anthropometric measures and 3-D feature envelopes of body landmarks for the design of tractor operator enclosures. One hundred agriculture wor...
The noise level in a tractor cab directly affects the driving experience. Reducing is an important means of improving image product brand and protecting physical psychological health employees. To reduce medium- low-frequency cab, influence installation coupled resonance acoustic materials (CRAMs) on driver ear investigated this study. Theories for sound absorption by perforated plates insulati...
The farm tractor fleet in the Brazilian market has increased. They are machines known to emit much noise. Noise can cause severe damage and disturbance people who work directly with around these machines. Therefore, aimed evaluate noise levels emitted by two cab tractors of different engine power, analyzing effect speed distance radius from source on occupational health. level outside inside ca...
Fatalities due to tractor overturns have long plagued the U.S. farm community. Constituting 20% of agricultural fatalities, tractor overturns contribute significantly to high rates of fatal injuries. In the past, many efforts have been directed toward reducing tractor overturns, with one successful US-based program offering rebates to farmers who retrofit their tractors with rollover protective...
OBJECTIVE The purpose of this systematic review was to evaluate the effectiveness of roll-over protection structures (ROPS) as an engineering control for prevention of fatalities from farm tractor roll-overs. METHODS Using a systematic approach to literature searching, relevant studies from peer-reviewed journals, technical and government reports, and unpublished reports were retrieved. Studi...
OBJECTIVES This article presented four anthropometric theories (univariate, bivariate/probability distribution, multivariate, and shape-based methods) for protective equipment design decisions. BACKGROUND While the significance of anthropometric information for product design is well recognized, designers continue to face challenges in selecting efficient anthropometric data processing method...
Simultaneous (or concurrent) Engineering, is a concept which should be normal nowadays. Then, without early and simultaneous involvement of all departments, specialists, special suppliers and potential external consultants, you are no longer able to develop these ever more complex agricultural machines. In that case „simultaneous“ means to be faster on the market, because all manufacturers can ...
Topographical distribution of concanavalin A binding sites (CABS) was studied in two lines of virally transformed fibroblasts as a function of fatty acid composition. Fatty acid composition was manipulated by incubating cells in fatty acid, ATP, CoA, and delipidated fetal calf serum (FCS). VLM cells grown in medium containing 5% FCS have a clustered CABS distribution. Plasma membrane vesicles (...
Potassium-competitive acid blockers (P-CABs) are highly safe and active drugs targeting H+,K+-ATPase to cure acid-related gastric diseases. In this study, we for the first time investigate the interaction mechanism between the protonated form of P-CABs and human H+,K+-ATPase using homology modeling, molecular docking, molecular dynamics and binding free energy calculation methods. The results e...
