Morphogen Transport in Epithelia

open access: yes, 2006
We present a general theoretical framework to discuss mechanisms of morphogen transport and gradient formation in a cell layer. Trafficking events on the cellular scale lead to transport on larger scales. We discuss in particular the case of transcytosis

A CRY-BIC negative-feedback circuitry regulating blue light sensitivity of Arabidopsis. [PDF]

open access: yes, 2017
Cryptochromes are blue light receptors that regulate various light responses in plants. Arabidopsis cryptochrome 1 (CRY1) and cryptochrome 2 (CRY2) mediate blue light inhibition of hypocotyl elongation and long-day (LD) promotion of floral initiation. It

The Effect of Boron-Containing Layered Hydroxy Salt (LHS) on the Thermal Stability and Degradation Kinetics of Poly (Methyl Methacrylate) [PDF]

open access: yes, 2010
A boron-containing layered hydroxy salt (LHS), ZHTMDBB, was prepared and compounded with a highly flammable synthetic polymer, poly (methyl methacrylate) {PMMA}, via melt blending: the composite structure was intercalated with poor dispersion. The effect

The Photocatalytic, Thermal Degradation Kinetics and Lifetime Prediction of Some Commercial Reactive Dyes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2017
The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts ...

Enhancement of perfluorooctanoate and perfluorooctanesulfonate activity at acoustic cavitation bubble interfaces [PDF]

open access: yes, 2008
Acoustic cavitation driven by ultrasonic irradiation decomposes and mineralizes the recalcitrant perfluorinated surfactants perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA).

Mechanisms of High Temperature Degradation of Thermal Barrier Coatings. [PDF]

open access: yes, 2009
Thermal barrier coatings (TBCs) are crucial for increasing the turbine inlet temperature (and hence efficiency) of gas turbine engines. The thesis describes PhD research aimed at improving understanding of the thermal cycling failure mechanisms of ...

Carotenoid stability in grains of maize hybrids compared to complete feeds for laying hens following preparation and storage

open access: yesApplied Food Research
Yellow maize grain is an important source of carotenoids for yolk pigmentation, but carotenoids are susceptible to degradation during storage of feeds for laying hens.
