A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Three-dimensional advanced numerical approaches to the seismic soil and structural response analyses [PDF]

, 2016
A 3D non-linear finite element approach is developed to study the free-field seismic ground response and the soil-structure interaction (SSI) phenomena at the Lotung site (Taiwan) during the earthquake event occurred on May 20 1986.

Influence of Backfill Soil on the Uplift Bearing Capacity of Prefabricated Foundations for Temporary Transition Towers

Buildings
In response to the non-reusable nature and prolonged construction period of traditional foundations for temporary and transitional towers, this paper designs a fully reusable all-metal prefabricated foundation for 35 kV–110 kV transmission lines.

The cone penetration test in unsaturated silty sands

E3S Web of Conferences, 2016
Very little is known about how to interpret the cone penetration test (CPT) when performed in unsaturated soils. The few published studies on the CPT in unsaturated soils have focused on either clean sands or a silt.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Behaviour of micropiles in heterogeneous coarse soils [PDF]

, 2016
This paper reports on an experimental investigation on the behaviour of small-diameter piles, commonly referred to as micropiles. This particular type of deep foundation is frequently used in many barely accessible Italian mountainous areas, often ...

Effects of deficit irrigation and biostimulants on melon productivity and quality in semi‐arid conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Soil Particle Size Distribution Protocol [PDF]

, 2003
The purpose of this resource is to sure the distribution of different sizes of soil particles in each horizon of a soil profile. Using dry, sieved soil from a horizon, students mix the soil with water and a dispersing solution to completely separate the ...

Yielding in the isotropic compression of Porto silty sand

, 2012
Analizirano je mesto popuščanja dobro zrnjavega meljnega peska s testi enakosmernega stiskanja in skenerjevim elektronskim mikroskopiranjem (SEM). Testi so izvedeni z natančnimi instrumenti, za notranje in zunanje meritve deformacij, in meritve hitrosti strižnega valovanja s pomočjo upogibnih elementov.
