Development of a long-term durability specification for polymer modified asphalt
(2009-06-02)
In recent years an increased use of polymers has occurred to modify asphalt
binders, mainly to decrease pavement rutting but also to improve binder failure strain in
direct tension. Whereas all of these effects positively ...
Regulation of cytochrome P450 3A4 gene expression through modulating pregnane X receptor transcriptional activity by NF-ꢬ aryl hydrocarbon receptor and xenobiotics
(2009-05-15)
Cytochrome P450 3A4 (CYP3A4) is a key enzyme responsible for the metabolism of drugs and endogenous compounds in human liver and intestine. CYP3A4 gene expression is mainly regulated by Pregnane X receptor (PXR) which is ...
Poetry, prayer, and pedagogy: writings by and for the English Catholic community, 1547-1650
(2009-05-15)
This study examines the role of religious poetry and pedagogy in
maintaining the English Catholic community during the Reformation and
Counter-Reformation. English Catholics faced legal sanctions, social isolation,
and ...
Dissolution of oxygen reduction electrocatalysts in acidic environment
(2009-05-15)
Platinum (Pt) alloy nanoparticles are used as catalysts in electrochemical cells to
reduce oxygen to water and to oxidize hydrogen; the overall reaction converts chemical
energy into electrical energy. These nanocatalysts ...
A new iterative approach to solving the transport equation
(2009-05-15)
We present a new iterative approach to solving neutral-particle transport
problems. The scheme divides the transport solution into its particular and
homogeneous or “source-free” components. The particular problem is solved ...
Mechanistic characterization of members of the amidohydrolase superfamily
(2009-05-15)
The amidohydrolase superfamily is a functionally diverse group of enzymes
found in every organism sequenced to date. The landmark for this superfamily is the
conservation of a (beta/alpha)8-barrel structural fold. Isoaspartyl ...
Environmental color for pediatric patient room design
(2009-05-15)
Color has a large impact on our psychological and physiological responses. This study examines the value of color as a component in a healing environment for pediatric patient rooms by measuring color preferences among ...
Percieved influence of societal dissonance, self-efficacy, African American male mentorship, and institutional support on the success of African American Males in a predominantly whie insitution of higher education
(2009-05-15)
For the past decade the attainment gap in college admission and graduation rates between Black males and their White counterparts has continued to grow. A growing body of research has held that there is a negative correlation ...
A case study of seven Taiwanese English as a foreign language freshman non-English majors' perceptions about learning five communication strategies
(2009-05-15)
The primary purpose of this study was to identify what were Taiwanese
University English as a Foreign Language (EFL) learners’ perceptions about learning
communication strategies. This study collected qualitative data about ...
Mechanisms of transcriptional activation of estrogen responsive genes in breast cancer cells
(2009-06-02)
Estrogen receptor (ER) acts as a ligand-activated transcription factor that regulates the expression of genes. The genomic mechanisms of ER action include ligand-induced dimerization of ER which binds estrogen responsive ...
