The penetration resistance as a soil degradation indicator in the viticulture

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
This paper deals with monitoring of changes in soil compaction at two experimental sites (Lednice and Valtice) in the alleyway of vineyards. The experimental measurements were carried out during the period 2009–2011. Penetration resistance of the soil was measured using the penetrometer (type PN 10) to a depth up to 520 mm.

SIMPLE CORRECTION METHOD OF SOIL PENETRATION RESISTANCE FOR SOIL WATER CONTENT

Engenharia Agrícola, 2022
ABSTRACT Soil penetration resistance (PR) assessment is a physical assessment of soil to identify compacted soil layers. Its results are influenced by soil moisture. In this study, a method for correcting PR as a function of soil water content is proposed.

Soil conditions and bounds to suction during the installation of caisson foundations in sand [PDF]

, 2014
Suction installation of caisson foundations is widely adopted in the oil offshore industry. When such foundations are installed in sand, seepage conditions are known to play a pivotal role in the installation process.

<b>Soil penetration resistance mapping quality: effect of the number of subsamples [PDF]

Acta Scientiarum. Agronomy, 2018
There is no consensus in the literature regarding how many subsamples are needed to perform accurate on-farm soil penetration resistance (SPR) mapping. Therefore, the objective of this study was to define the number of subsamples per sampling point needed to quantify the SPR.

Determination of Some Soil Properties on Penetration Resistance and Consistency Limits

, 2022
Atterberg limits and penetration resistance are the factors that affect the mechanical behavior of soil. In this study, it was investigated the direct and indirect effect of some soil properties such as particle size distribution, moisture and organic ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Estimating Penetration Resistance in Agricultural Soils of Ardabil Plain Using Artificial Neural Network and Regression Methods

مجله آب و خاک, 2017
Introduction: Penetration resistance is one of the criteria for evaluating soil compaction. It correlates with several soil properties such as vehicle trafficability, resistance to root penetration, seedling emergence, and soil compaction by farm ...

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 ...
