Microbial community structure and carbon transformation characteristics of different aggregates in black soil [PDF]

open access: yesPeerJ
Background Previous research on whole-soil measurements has failed to explain the spatial distribution of soil carbon transformations, which is essential for a precise understanding of the microorganisms responsible for carbon transformations.

The Effects of Land Usage on Water-stable Soil Aggregates in Karst Canyon Region

open access: yesGuan'gai paishui xuebao, 2021
【Objective】 Aggregate is a basic functional unit in soil to characterize the impact of soil structure on soil functions. It changes with agricultural practice and land management.

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.

Impact of Integrated Rice-Crayfish Farming on Soil Aggregates and Organic Matter Distribution

open access: yesAgronomy, 2023
This study evaluates the effects of a combined rice-crayfish farming model and compares this model with traditional paddy fields. The focus is on soil aggregate characteristics, organic matter content, and also the distribution of soil aggregates.

Pore system characteristics of soil aggregates and their relevance to aggregate stability

open access: yesGeoderma, 2020
Aggregates are the structural units of soils, and the physical stability is considered to be a keystone parameter of soil quality. However, little is known about the evolution of the pore system in aggregates and its importance in defining aggregate ...

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

Change in Soil Aggregation During the Freezing-thawing Fallow Season was Affected by Agronomical Management

open access: yesGuan'gai paishui xuebao, 2022
【Objective】 Soil aggregate is a functional unit used to describe the effect of management practices on soil physical properties and soil functions. It is dynamic and varies with various factors.

THE INFLUENCE OF HUMUS ON SOIL AGGREGATION

open access: yesJournal of Soil Science, 1950
Summary S everal methods were used for extracting humus from a number of widely different soil types. The cementing power of the various humates was tested by mixing them with soil and determining the weight of water‐stable aggregates surviving wet sieving.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
