Handwashing and Ebola virus disease outbreaks: A randomized comparison of soap, hand sanitizer, and 0.05% chlorine solutions on the inactivation and removal of model organisms Phi6 and E. coli from hands and persistence in rinse water. [PDF]

open access: yesPLoS ONE, 2017
To prevent Ebola transmission, frequent handwashing is recommended in Ebola Treatment Units and communities. However, little is known about which handwashing protocol is most efficacious.

Design of Smart Weed Control System with Consideration of Herbicide Persistence Using Supervised Learning

open access: yesChemical Engineering Transactions, 2023
One of the factors that affect the quality and quantity of crops is due to stress factors caused by weeds. The presence of weeds in a field of crop is always stressful for the crop plant due to the competition for nutrients, light and moisture ...

Persistent Activities of Extracellular Enzymes Adsorbed to Soil Minerals

open access: yesMicroorganisms, 2020
Adsorption of extracellular enzymes to soil minerals is assumed to protect them against degradation, while modifying their activities at the same time. However, the persistence of the activity of adsorbed enzymes remains poorly understood.

High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]

open access: yes, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

Native and invasive inoculation sources modify fungal community assembly and biomass production of a chaparral shrub [PDF]

open access: yes, 2020
Feedbacks between plants and surrounding soil microbes can contribute to the establishment and persistence of invasive annual grasses as well as limit the success of restoration efforts.

The relevance of the evolution of experimental studies for the interpretation and evaluation of some trace physical evidence [PDF]

open access: yes, 2009
In order for trace evidence to have a high evidential value, experimental studies which mimic the forensic reality are of fundamental importance.

Persistence of microbial extracellular enzymes in soils under different temperatures and water availabilities

open access: yesEcology and Evolution, 2020
Microbial extracellular enzyme activity (EEA) is critical for the decomposition of organic matter in soils. Generally, EEA represents the limiting step governing soil organic matter mineralization.

Composted Sewage Sludge Influences the Microbiome and Persistence of Human Pathogens in Soil

open access: yesMicroorganisms, 2020
Composted sewage sludge (CSS) gained attention as a potential fertilizer in agriculture. Application of CSS increases soil microbial activity and microbial biomass, however, it can also lead to increased chemical and microbiological risks. In this study,

Burial and seed survival in Brassica napus subsp. oleifera and Sinapis arvensis including a comparison of transgenic and non-transgenic lines of the crop [PDF]

open access: yes, 1997
The creation of transgenic plants through genetic engineering has focused interest on how the fitness of a plant species may be altered by small changes in its genome. This study concentrates on a key component of fitness: persistence of seeds overwinter.

Assessing the soil moisture-precipitation feedback in Australia: CYGNSS observations

open access: yesEnvironmental Research Letters, 2023
Previous modelling and case studies highlight the impacts of antecedent soil moisture on precipitation, showing the connection between the anomalous land surface and atmospheric conditions.
