Stabilisation with geogrids for transport applications – selected issues [PDF]

MATEC Web of Conferences, 2019
Stabilisation is defined as improvement of the mechanical properties of an unbound granular material by including one or more geosynthetic layers such that the deformation under applied loads is reduced by minimizing soil particle movement. Paper discuss

Geotechnical viability of sand, cement, and binary stabilisation of soils in the western Niger Delta; An example of Warri City, Southern Nigeria

Journal of the Geological Survey of Brazil
The pavement performance of superficial soils in southern Nigeria is in decline, most notably due to the use of inferior pavement materials and poor soil conditions.

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.

Effect of moisture content on alkali-activated stabilisation of expansive soils

Case Studies in Construction Materials
This study presents a comparative evaluation of two slag-based alkali-activated stabilisation approaches for expansive soils, distinguished by the initial moisture contents of the treated soil: (i) optimum moisture content, OMC, (in a moist state) and ...

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 ...

Efficacy of expansive soil stabilisation using un-calcinated Kaolinite-Based Alkali-Activated binders

Cleaner Materials
In recent years, alkali-activation and geopolymerisation have emerged as sustainable alternatives for stabilising expansive soils, traditionally treated with lime or cement. While most studies focus on high-temperature-processed materials such as fly ash,

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

Advanced 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 ...
