Amino-acids in Soil

Nature, 1950
ALTHOUGH the protein nature of at least one-third of the organic nitrogen of soil has been established1,2, very little is known of the amino-acid composition of this protein material. The isolation of amino-acids from soil hydrolysates is rendered difficult by the presence of large amounts of extraneous inorganic and organic material.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Precision estimation of lime requirements in acidic soils using varied soil acidity indices under contrasting application methods in northwest Ethiopia

Discover Environment
Soil acidity is a major constraint to crop productivity in intensively cultivated humid and sub-humid regions worldwide. Accurate estimation of lime requirement (LR) remains challenging due to spatial variability in soil buffering capacity and the use of

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced 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.

Soil Erosion: Types and Their Mechanism

International Journal of Economic Plants, 2015
Soil erosion is a universal phenomenon. Out of the 328.7 m ha of India’s geographical area about 175 m ha (53.3%) is subjected to soil erosion and some kind of land degradation.

Soil acidity as affecting micronutrients concentration, nitrato reductase enzyme activity and yield in upland rice plants

Semina: Ciências Agrárias, 2013
The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Long-Term Application of Pig Manure to Ameliorate Soil Acidity in Red Upland

Agriculture, 2023
While the application of manure to improve soil quality has attracted attention, the effect of pig manure application rates on soil acidity remains poorly understood. In this study, we analyzed the changes and correlations between soil acidity, pH buffer
