Mechanical weed control [PDF]

, 2018
Evolution of herbicide resistance in weeds has increased the importance and scope of mechanical weed control. In many parts of the world, the efficacy of mechanical weed control has been reevaluated.

Mechanisms for usage control [PDF]

Proceedings of the 2008 ACM symposium on Information, computer and communications security, 2008
Usage control is a generalization of access control that also addresses how data is used after it is released. We present a formal model for different mechanisms that can enforce usage control policies on the consumer side.

The Mechanisms of Alcohol Control [PDF]

SSRN Electronic Journal, 2014
A substantial economics literature documents that tighter alcohol controls reduce alcohol-related harms, but far less is known about mechanisms. We use the universe of Canadian mortality records to document that Canada's Minimum Legal Drinking Age (MLDA) significantly reduces mortality rates of young men but has much smaller effects on women.

Mechanisms controlling the mechanical properties of the nuclei

Current Opinion in Cell Biology, 2023
The mechanical properties of the nucleus influence different cellular and nuclear functions and have relevant implications for several human diseases. The nucleus protects genetic information while acting as a mechano-sensory hub in response to internal and external forces.

Tracking control of mechanical systems with a unilateral position constraint inducing dissipative impacts [PDF]

, 2012
In this paper, the tracking control problem is considered for mechanical systems with unilateral constraints with dissipative impacts. In these systems, impacts are triggered at the exact moment when the constraint becomes active.

On the Mechanism of Respiratory Control [PDF]

The Journal of General Physiology, 1965
Control of oxidation is the key mechanism in the regulation of energy metabolism. In glycolysis the oxidation of glyceraldehyde-3-phosphate is controlled by DPNH, which inhibits glyceraldehyde-3-phosphate dehydrogenase. In oxidative phosphorylation the inhibition of electron flow from DPNH to oxygen, called "respiratory control," is the subject of this

Mechanical work performed by individual limbs of transfemoral amputees during step-to-step transitions: Effect of walking velocity [PDF]

, 2014
The greater metabolic demand during the gait of people with a transfemoral amputation limits their autonomy and walking velocity. Major modifications of the kinematic and kinetic patterns of transfemoral amputee gait quantified using gait analysis may ...

A power-based perspective of mechanical systems [PDF]

, 2005
This paper is concerned with the construction of a power-based modeling framework for a large class of mechanical systems. Mathematically this is formalized by proving that every standard mechanical system (with or without dissipation) can be written as ...

Glyphosate-Resistant Sourgrass Management Programs Associating Mowing and Herbicides [PDF]

Planta Daninha
: Currently, sourgrass is one of the most important weeds in grain production areas in Brazil. The objective of this work was to evaluate the efficiency of associated systems composed by mowing and chemical control against clumped sourgrass. In the first
