Interaction between Edge-Crack and Aggregate in Silicate-Based Composite

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
The paper deals with investigation of the interaction between an edge-crack and an aggregate in a silicate-based composite, because adding of aggregates into basic matrix material can improve the fracture mechanical properties of the material ...

Effect of Coarse Aggregate Characteristics on Drying Shrinkage of Concrete [PDF]

open access: yesEngineering and Technology Journal, 2008
Concrete is a composite material, consisting, mainly, of three phases: coarseaggregate, cement mortar, and the interface zone between them. The characteristicsof the interface zone largely govern the bond between cement paste or mortar andaggregate.

Additional measures of progress for Scotland : an analysis of the issues and problems associated with aggregate/composite measures of sustainability [PDF]

open access: yes, 2007
the purpose of this paper is to consider the broad set of issues and problems associated with adopting aggregate measures of sustainability. We do this by first considering what we mean when we talk about 'sustainable development' in a policy context and

Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...

Optimization Design of the Mix Ratio of a Nano-TiO2/CaCO3-Basalt Fiber Composite Modified Asphalt Mixture Based on Response Surface Methodology

open access: yesApplied Sciences, 2020
This research optimizes the mix ratio of nano-TiO2/CaCO3 (NTC)-basalt fiber (BF) composite modified asphalt mixture. Based on the Box–Behnken method and the response surface method, a three-factor and three-level test was designed.

Modeling carbon black reinforcement in rubber compounds [PDF]

open access: yes, 1996
One of the advocated reinforcement mechanisms is the formation by the filler of a network interpenetrating the polymer network. The deformation and reformation of the filler network allows the explanation of low strain dynamic physical properties of the ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
