Experimental study and modeling on effective thermal conductivity of EPS lightweight concrete

open access: yesJournal of Thermal Science and Technology, 2016
The effect of expanded polystyrene (EPS) inclusions on thermal conductivity of lightweight concrete is studied. Various mixtures are produced by incorporating EPS aggregate at different volumes (0%, 10%, 20%, 30% and 40%) in concrete with three water ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

A method for rapid estimation of residual stresses in metal samples produced by additive manufacturing

open access: yesFracture and Structural Integrity
The mechanical methods for measuring residual stresses typically rely on so-called destructive techniques where some stress components can be determined based on part deflection after material removal (cutting, etching, drilling, etc.).

Influence of Annealing treatment on Microstructure and Properties of Cold-drawn Al-3.0wt.%Mg Alloy

open access: yesInternational Journal of Electrochemical Science, 2021
The influence of annealing treatment on the microstructure, mechanical properties and corrosion behavior of cold-drawn Al-3.0 wt%Mg alloy was investigated by 2D-XRD, microstructure observation, tensile test, immersion test and electrochemical measurement.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Integration of macro- and microdamage mechanics for the performance evaluation of composite materials

open access: yes, 2012
When subjected to mechanical loads, composite materials can generate complex configurations of multiple cracks that collectively change the average material response and thereby the performance, e.g., the fatigue life. Over many years, various approaches

High Mechanical Properties of AZ91 Mg Alloy Processed by Equal Channel Angular Pressing and Rolling

open access: yesMetals, 2019
Mechanical properties usually take precedence for wrought magnesium alloy when it would be used as a structure material. This paper proposed an approach that achieved high strength in AZ91 Mg alloy.

High temperature rise dominated cracking mechanisms in ultra-ductile and tough titanium alloy

open access: yesNature Communications, 2020
Specific titanium alloys combine transformation-induced plasticity and twinning-induced plasticity for improved work hardening. Here, the authors show that these alloys also have an ultra-large fracture resistance and an unexpected fracture mechanism via
