Last Glacial Maximum and deglacial branched GDGT‐based palaeotemperature reconstruction from a subtropical Australian wetland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Future projections of climate change in the subtropics suggest warming and drying, while evidence from warm periods in the past shows increases in subtropical temperatures and precipitation. Eastern Australia is subject to interannual hydroclimate drivers and has experienced extreme flooding and droughts in recent years.

Microplastics Identification in Remote Aquatic Environments Using Raman Spectroscopy: A Case Study for Mt. Tymfi's Alpine Lake

open access: yesJournal of Raman Spectroscopy, EarlyView.
This work contributes to the literature on the detection of MPs in Greece, proposes a method for MPs extraction in remote environments taking into account fieldwork constraints of an expedition in the Greek Alps, and takes a step forward in MPs analysis by Raman spectroscopy. ABSTRACT Water samples from the alpine lake of Mt.

Effect of Hydrofracking on Aquifers

open access: yes, 2018
Geologists have understood the presence of shale gas and shale oil since the early 20th century, but always considered it unattainable due to shale’s low permeability. The shale gas revolution in the United States, brought about by the combination of horizontal drilling and hydraulic fracturing has proven the feasibility of economically accessing ...

Influence of continuous and pulsed light on the yield and phytochemical composition of Capsicum annuum L. cv. ‘Padrón’

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sweet pepper (Capsicum annuum) is of considerable socio‐economic importance and is among the most widely cultivated vegetables worldwide, occupying more than 20 000 km2. Light‐emitting diodes (LEDs), applied in continuous or pulsed modes, can increase yield and improve the phytochemical composition in indoor production systems ...

Using H‐Convergence to Calculate the Numerical Errors for 1D Unsaturated Seepage in Transient Conditions

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical modeling plays a pivotal role in understanding transient unsaturated flow, which is critical for applications such as groundwater recharge, stormwater management, and contaminant transport. This study investigates the effect of time step refinement on numerical solutions for a vertical infiltration 1D test in a vertical column. First,

Acuíferos en Chihuahua: estudios sobre sustentabilidad

open access: yesTecnociencia Chihuahua, 2019
El manejo no sustentable de acuíferos puede manifestarse como un déficit (recarga-extracciones), el cual se refleja en un descenso del nivel potenciométrico con respecto al tiempo, y también en el deterioro en la calidad del agua. Una manera
