Free vibration analysis of a string with vibration suppressor located at 1/N of the string (When N is an odd number)

Nihon Kikai Gakkai ronbunshu, 2016
A vibration suppressor is used to change the natural frequency of an elevator rope, and to prevent resonance. The elevator rope is modeled using a string. Linear string vibration is well known.

Swimming Upriver? Exploring the Sources of Freshwater and Marine Fish in Military Diet in Sixteenth‐ to Nineteenth‐Century Northeastern North America

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Atlantic cod were caught in large numbers and shipped from fishing stations in North America to Europe and the Caribbean, and this has been frequently studied zooarchaeologically; however, the exchange of cod and other fish into interior North America has received less study.

Asymmetrical Steps: Osteomorphological and Metric Patterns of Cattle Phalanges to Determine Anatomical Position

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study presents a reproducible framework for identifying the anatomical position of cattle phalanges, integrating both morphological and osteometric approaches for application to modern and zooarchaeological assemblages. The dataset comprises 1853 phalanges from 106 individuals with known and unknown phalangeal position representing ...

How can children and young people have a voice in urban treescapes?

People and Nature, EarlyView.
Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Postural Stabilization Strategies to Motor Contagion Induced by Action Observation Are Impaired in Parkinson’s Disease

Frontiers in Neurology, 2018
Postural reactions can be influenced by concomitant tasks or different contexts and are modulated by a higher order motor control. Recent studies investigated postural changes determined by motor contagion induced by action observation (chameleon effect)

From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

PLANTS, PEOPLE, PLANET, EarlyView.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...
