Model coupling friction and adhesion for steel-concrete interfaces [PDF]
International Journal of Computer Applications in Technology 34, 1
(2009) 42-51, 2010 The interface behaviour between steel and concrete, during pull-out tests, is numerically investigated using an interface model coupling adhesion and Coulomb friction. This model, first developed by Raous, Cang\'emi, Cocou and Monerie (RCCM), is based on the adhesion intensity variable, introduced by Fr\'emond, which is a surface damage variable.

Advanced Science, EarlyView.A new strategy for constructing smart gel‐based MN patches is developed to overcome the insufficient drug delivery of eye drops to the lacrimal gland. The gel‐based MN patches achieved long‐acting drug release in a ROS‐responsive manner, and separable base in a temperature‐responsive manner.

arXiv, 2011 It is commonly believed that the ancient Romans were the first to create and use concrete. This is not true, as we can easily learn from the Latin literature itself. For sure, Romans were able to prepare high-quality hydraulic cements, comparable with the modern Portland cements.

Properties and performance of high strength fibre reinforced concrete by using steel and polypropylene fibres [PDF]
, 2019 Many reinforced concrete structures suffer severe degradation due to the effect from freezing and thawing, shrinkage and expansion, aggressive environment, earthquake and drastic increase of live loads.

Advanced Science, EarlyView.Klinefelter syndrome‐derived iPSCs provide an excellent model for studying X chromosome inactivation and functions of escapee genes during human primordial germ cell‐like cells differentiation process. Downregulation of three X‐linked genes—IGSF1, CHRDL1, and USP9X—significantly enhances the efficiency of hPGCLCs.

Advanced Science, EarlyView.The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Transmission factors and exposure to infections at work and invasive pneumococcal disease
American Journal of Industrial Medicine, Volume 66, Issue 1, Page 65-74, January 2023., 2023 Abstract Background Working in close contacts with coworkers or the general public may be associated with transmission of invasive pneumococcal disease (IPD). We investigated whether crowded workplaces, sharing surfaces, and exposure to infections were factors associated with IPD.

Material Thermal Inputs of Iowa Materials for MEPDG, 2011 [PDF]
, 2011 The thermal properties of concrete materials, such as coeffi cient of thermal expansion (CTE), thermal conductivity, and heat capacity, are required by the MEPDG program as the material inputs for pavement design.

Advanced Science, EarlyView.Assessing species' vulnerabilities across geographical gradients is essential for biodiversity conservation under climate change. To address this challenge, the semi‐natural climate chamber across latitudes (SCCAL) is developed, a validated system capable of simulating thermal environments for ecological experiments without reliance on water or ...
