Relationship between the mass of organic matter and carbon in soil

open access: yesBrazilian Archives of Biology and Technology, 2008
The quantity of soil organic matter (SOM) was estimated through the determination of soil organic carbon (SOC) times a factor, which assumes that 58% of the SOM was formed by carbon.

Microplastic Analysis in Soils: A Comparative Assessment

open access: yesEcotoxicology and Environmental Safety, 2023
Microplastic (MiP) contamination poses environmental risks, but harmonizing data from different quantification methods and sample matrices remains challenging. We compared analytical protocols for MiP quantification in soil, consisting of Digital, Fluorescence, Fourier-transform infrared (FTIR), and Raman Microscopy as well as quantitative Pyrolysis ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Gravimetric determination of soil organic matter

open access: yesBrazilian Archives of Biology and Technology, 2000
Studies were carried out to evaluate a gravimetric method for the determination of soil organic matter by the mass loss at 300ºC. The gravimetric method was compared with Walkley-Black, using several brazilian soils with variable chemical and physical ...

How phagocytic cells kill bacteria: Lessons from a professional killer

open access: yesFEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Conversion of Potato Fields into Small Tea Plantations at Bhotepatty, Mainaguri: Consequences of This Shifting Agriculture Through Survey and Soil Analysis

open access: yesContemporary Agriculture, 2023
Over the past years, the tea industry in India has started to suffer from various drawbacks, i.e. issues regarding low productivity and rising input costs (namely the uneconomic age profile of tea bushes across the tea estates of North Bengal), leading ...
