Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Mechanical Chiseling Versus Root Bio-Tillage on Soil Physical Quality and Soybean Yield in a Long-Term No-Till System

Agronomy
Occasional mechanical intervention can help alleviate compaction symptoms in no-till systems, but its effects compared to well-established crop rotation systems are uncertain.

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Sediment transport in runoff on rugous soil surface submitted to simulated rainfall Sedimentos transportados na enxurrada em superfície de solo rugosa submetida à chuva simulada

Scientia Agricola, 2010
Soil management influences water erosion and sediment size in runoff. With the objective of quantifying sediments in runoff and their relation to runoff velocity (Rv), random roughness (RR), and Ir index, this experiment was carried out from 2003 to 2006,

Folklore Studies, Fieldwork and the Making of a Domestic Anthropology in Fin‐de‐Siècle Britain

History, EarlyView.
Abstract This article follows the ‘communities of knowledge‐making’ that formed around folklore collection at the end of the nineteenth century. Often regarded as eccentric or marginal figures in the history of human science, these collectors in fact engaged in lively and sophisticated discussions about the methodologies needed to study the mental ...

Rendimento da soja e intervalo hídrico ótimo em latossolo vermelho sob plantio direto escarificado Soybean grain yield and least limiting water range in an oxisol under chiseled no-tillage

Revista Brasileira de Ciência do Solo, 2007
O intervalo hídrico ótimo (IHO) é um método que integra vários fatores que afetam o desenvolvimento das plantas, e corresponde ao intervalo de umidade do solo no qual não ocorre restrição de aeração (porosidade de aeração mínima de 0,10 m³ m-3) nem de ...

An Experimental Approach on Pearl Shell (Pinctada margaritifera) for a Microwear Study of Shell Artefacts From French Polynesia

Archaeometry, EarlyView.
ABSTRACT Pinctada margaritifera (black‐lipped pearl oyster) artefacts are ubiquitous in the archaeological record throughout the Pacific and particularly in Polynesia. Despite efforts towards the development of typologies, the lack of microwear and use‐wear studies has prevented the development of technological approaches. We used 20 pearl shell valves

LGM glaciation in the northern Dinaric Mountains, Slovenia: new insights from terrestrial cosmogenic nuclide dating and Parallel Ice Sheet Model simulation

Boreas, EarlyView.
The Dinaric Mountains are a mountain range stretching NW–SE from the Alps to the Albanides–Hellenides in central Europe. The highest parts were occupied by small ice fields and/or valley glaciers during the Quaternary cold periods, while even today some small glaciers still exist in topoclimatically favourable areas.
