Developmental Dynamics, EarlyView.Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

Journal of Materials and Engineering Structures, 2020 The fiber-reinforced polymer (FRP) retrofitting technique has been increasingly created to enhance the capacity of the existing concrete members. In this study, the shear contribution of the external FRP strengthening system in the reinforced concrete ...

FRP Strains in FRP Wrapped Columns
, 2007 Extensive research has been undertaken on strengthening concrete columns using FRP wraps. Recent research has extended this technique into strengthening steel tubular and concrete filled steel tubular columns. The behaviour of FRP confined concrete columns is now well understood and accurate models for both design and analysis are available.

Effects of existing cracks on FRP-to-concrete interfacial behavior
, 2017 The concrete structures which need to be strengthened by externally bonded (EB) FRP normally have existing cracks. In order to study the effects of the existing cracks on the bond slip relationship, an experimental program of single shear pull-out tests ...

Fire and Materials, EarlyView.ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Shear performance of existing reinforced concrete T-beams strengthened with FRP
, 2012 This paper presents the experimental behaviour of two reinforced concrete (RC) beams strengthened in shear with C-FRP. The beams are extracted from an important building of the '30s in Rome.

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objectives Obstetrics and gynecology (ObGyn) trainees will impact future practice patterns and their cesarean rates. The knowledge, attitudes, and practices (KAP) of ObGyn residents have not been extensively studied. We aimed to assess KAP towards mode of delivery and cesarean‐sparing procedures among ObGyn trainees.

Advances in Civil Engineering, 2020 Applying similar amount of fibre reinforced polymer (FRP) for all plastic hinge locations in a structure is not an ideal approach as damage occurring at these critical locations may vary considerably.

Numerical modeling of existing RC beams strengthened in shear with FRP U-sheets
, 2012 This paper presents a finite element analysis on two reinforced concrete beams, extracted from an important building of the '30s in Rome, strengthened in shear with C-FRP and subjected to the simultaneous occurrence of a negative bending moment and shear

Experimental study on Carbon FRP-confined elliptical concrete columns [PDF]
, 2011 It is well recognized that the technique of strengthening reinforced concrete (RC) using fiber-reinforced polymer (FRP) jackets is more effective for circular sections, but less effective for rectangular sections.
