Physical Properties of a Hapludox after Three Decades under Different Soil Management Systems

open access: yesRevista Brasileira de Ciência do Solo, 2016
Changes in soil physical properties due to different management systems occur slowly, and long-term studies are needed to assess soil quality. The objectives of this study were to evaluate the effects of soil management systems and liming methods on the ...

Soil Physical Properties and Production of Upland Ultisol Soil [PDF]

open access: yes, 2012
Acid upland soil in Indonesia has a great potential for agricultural development but the soil physical properties have been degraded. The use of manure and direct application of Gresik phosphate rock (PR) was an alternative to improve land productivity ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Cropping sequence influenced crop yield, soil water, and soil properties in wheat-camelina cropping system

open access: yesFarming System
Integrating camelina (Camelina sativa L. Crantz) into wheat (Triticum aestivum L.) -based cropping systems in the Great Plains Region of the United States could improve soil properties and overall system productivity. However, there is little information
