Comparative Effectiveness of Different Mulch Types and Application Rates for Reducing Runoff and Sediment Yield on Forest Skid Trails

Land Degradation &Development, EarlyView.
ABSTRACT Rehabilitation of skid trails following timber harvesting is critical for preserving forest soil integrity, particularly within ecologically sensitive ecosystems such as the Hyrcanian forests of northern Iran, a UNESCO World Heritage Site. Although mulching is widely recommended for erosion control, field evidence comparing different locally ...

THE EFFECT OF A 6-WEEK INDIVIDUAL ANAEROBIC THRESHOLD BASED PROGRAMME IN A TRADITIONAL ROWING CREW

Biology of Sport, 2012
The purpose of the present study was to analyse a 6-week IAT (individual anaerobic threshold) based work load programme in a subelite rowing crew. 15 male rowers performed a 6-week IAT based work load distributed in 2, 2, 3, 3, 3, 2 sessions per week. To

Arginine, scurvy and Cartier's "tree of life"

Journal of Ethnobiology and Ethnomedicine, 2009
Several conifers have been considered as candidates for "Annedda", which was the source for a miraculous cure for scurvy in Jacques Cartier's critically ill crew in 1536.

Ein Crew-Pairing und Recovery-Tool [PDF]

, 2020
Der tägliche Betrieb von Fluggesellschaften unterliegt zahlreichen Störungen, wie zum Beispiel Wetterereignissen oder technischen Problemen. Dies erfordert laufende Anpassungen der Planung am Tag des Fluges. Flugzeuge und Crews werden in sogenannten Umläufen geplant, welche ihrerseits das Ergebnis einer vorgelagerten Optimierung sind.

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

Limnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Morphological and physiological changes in mature in vitro neuronal networks towards exposure to short-, middle- or long-term simulated microgravity.

PLoS ONE, 2013
One of the objectives of the current international space programmes is to investigate the possible effects of the space environment on the crew health. The aim of this work was to assess the particular effects of simulated microgravity on mature primary ...

Energy Optimization Models for the Locomotive Assignment Problem

Networks, EarlyView.
ABSTRACT Reducing energy consumption is a key objective in transportation. Using detailed infrastructure data, this study introduces the Green Locomotive Assignment Problem (GLAP) to minimize energy consumption in railway operations by efficiently assigning locomotives to pre‐scheduled trains.

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

People and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

PLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...
