Effects of coastal saline-alkali soil on rhizosphere microbial community and crop yield of cotton at different growth stages

open access: yesFrontiers in Microbiology
Soil salinization is a global constraint that significantly hampers agricultural production, with cotton being an important cash crop that is not immune to its detrimental effects.

Impacts of Climate Change-Induced Salinity Intrusion on Physiological Parameters of Aquatic Hydrophytes from Coastal Rivers of Bangladesh [PDF]

open access: yes
Changing temperature, precipitation regimes, and sea level rise, often associated with climate change, cause salinity intrusion into groundwater and surface water, affecting aquatic ecosystems. This study investigates the impacts of salinity on the physiological traits of freshwater hydrophytes, including Water Hyacinth (Eichhornia crassipes), Buffalo ...

Competing advection decelerates droplet evaporation on heated surfaces [PDF]

open access: yesarXiv, 2020
In this article we report the atypical and anomalous evaporation kinetics of saline sessile droplets on surfaces with elevated temperatures. In a previous we showed that saline sessile droplets evaporate faster compared to water droplets when the substrates are not heated. In the present study we discover that in the case of heated surfaces, the saline

Global solutions to the stochastic heat equation with superlinear accretive reaction term and superlinear multiplicative noise term on a bounded spatial domain [PDF]

open access: yesarXiv, 2021
We describe sufficient conditions on the reaction terms and multiplicative noise terms of a stochastic reaction-diffusion equation that guarantee that the solutions never explode. Both the reaction term and multiplicative noise terms are allowed to grow superlinearly.

Land Degradation and Climate Change in Africa [PDF]

open access: yes, 2020
Land degradation is rampant in Africa, accounting for 46% of the total land area. Land degradation at the current pace is projected to render more than half of the cultivated land in Africa unusable by 2050.

Surface salinity fields in the Arctic Ocean and statistical approaches to predicting anomalies and patterns [PDF]

open access: yesarXiv, 2014
Significant salinity anomalies have been observed in the Arctic Ocean surface layer during the last decade. Using gridded data of winter salinity in the upper 50 m layer of the Arctic Ocean for the period 1950-1993 and 2007-2012, we investigated the inter-annual variability of the salinity fields, attempted to identify patterns and anomalies, and ...

Normal Saline [PDF]

open access: yesAMA Journal of Ethics, 2019
In 2017, Hurricane Maria devastated Puerto Rico and prompted a shortage of normal saline in US health care organizations. This graphic narrative considers ethics and justice in the supply, demand, and allocation of intravenous fluids in clinical settings during this time.
