Analytical Solution for Consolidation of Vertical Drains-Impervious Piles with Multiple Composite Foundations under Nonuniform Initial Pore Pressure and Time-Dependent Well Resistance

Advances in Civil Engineering, 2022
For the vertical drains-impervious pile multiple composite foundation consolidation problem, the effects of nonuniform distribution of initial pore pressure, variation of well resistance with time, and combined radial and vertical seepage in the soil are

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Evaluation of the Self-Weight Consolidation of Clay-Rich High Water Content Slurries in a Benchtop Centrifuge

Geotechnics
Oil sands tailings consist of a combination of sand, fine particles, water, and residual unextracted bitumen in varying ratios. The management of these mine waste tailings is largely influenced by their consolidation behavior.

Large-strain consolidation modeling of mine waste tailings [PDF]

Environmental Systems Research, 2013
Sustainable management of mine waste tailings during operation, closure, and reclamation requires a clear understanding of modeling the large-strain consolidation behaviour of these loose and toxic slurries. A state-of-the-art was presented focusing on process phenomenology and coordinate systems for tailings dewatering thereby devising a simple ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Large-Strain Consolidation Analysis Accounting for Time-Dependent Effects in Clayey Tailings and Soft Soils

, 2023
Soft soils and clayey tailings exhibit time-dependent behavior due to factors like creep, structuration/destructuration which can significantly influence consolidation processes.

Nonlinear consolidation analysis of soft soil foundations considering large strain and non-darcian flow under temperature effects

Yantu gongcheng xuebao
The theory of thermal consolidation is widely applied in engineering projects such as ground source heat pumps, energy piles, and heating pipelines, which involve thermo-hydro-mechanical coupling in geomaterials. The physical and mechanical properties of

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
