Neuroprotective Effects of Senecio brasiliensis Extract Against Chlorpyrifos-Induced Neurotoxicity and Oxidative Stress in Drosophila melanogaster. [PDF]
Basic Clin Pharmacol ToxicolABSTRACT Chlorpyrifos (CP) is an organophosphate insecticide that induces neurotoxicity through acetylcholinesterase (AChE) inhibition and redox imbalance, raising environmental and occupational health concerns. Plant‐derived compounds from Senecio brasiliensis, native to the Pampa biome, offer multitarget therapeutic potential.

Informes de la Construccion, 1964 La pasarela recientemente construida en Des Moines (EE. UU.), presenta la notable particularidad de tener sus accesos en curva y apoyarse sobre pilares de forma cilíndrica. Como el terreno no tenía suficiente resistencia de sustentación se tuvo que reforzar hincando pilotes para hormigonar, sobre ellos, la solera en la que descansa el montante ...

MODELLING OF PEDESTRIAN-INDUCED LOAD IN SERVICEABILITY LIMIT STATE ANALYSIS OF FOOTBRIDGES
Facta Universitatis. Series: Architecture and Civil Engineering, 2022 The last few decades new trends in the design of pedestrian bridges have resulted in lighter and more slender structures. This leads to a reduction in natural frequencies and increased flexibility, and thus a greater possibility for structures to become ...

Vertical Vibrations of Footbridges Due to Group Loading: Effect of Pedestrian–Structure Interaction
Applied Sciences, 2021 The vibration serviceability of footbridges has evolved from the adoption of a single pedestrian crossing in the resonance condition to load cases in which several pedestrians cross the structure simultaneously.

Design of an emergency footbridge
WIT Transactions on The Built Environment, 2014 This paper will describe the design of a temporary emergency floating footbridge, to be made when the infrastructure is destroyed by a flood, hurricane, tsunami or any other disaster. The bridge is made of identical floating modules. The modules are composed of prefabricated elements: two trusses, a pontoon and the footpath.
