Blowout Risk Assessment Method of Screw Conveyor in Earth Pressure Balance Shield Tunneling through Water-bearing Sand Layers

Chengshi guidao jiaotong yanjiu
[Objective] During shield tunneling in water-bearing sand layers, due to abundant groundwater and high soil permeability, screw conveyors are highly prone to blowout incidents. If control measures are inadequate, serious construction safety accidents may

Influence of the contractor’s payment method on the economic effectiveness of the construction project from the contractor’s point of view

Open Engineering, 2018
The scope of the paper is the problem of the economic effectiveness of the construction project from the contractor’s point of view. The two main construction contract types are taken under consideration: the unit price contract based on the bill of ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Predicting construction cost under uncertainty using grey-fuzzy earned value analysis

Heliyon
Insufficient emphasis on planning and control is one of the major causes of several delayed and cost-overrun construction projects. To improve such performances, many studies have been conducted on project control techniques such as Earned Value Analysis

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...
