Completeness of beta-phase decomposition reaction in Cu-Al-Ag alloys
(Springer, 2012-08-01)
The completeness of beta-phase decomposition reaction in the Cu-11wt%Al-xwt%Ag alloys (x = 0, 1, 2, and 3) was studied using differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and optical microscopy (OM). ...
beta Phase transformations in the Cu-11mass%Al alloy with Ag additions
(Springer, 2011-11-01)
In the Cu-Al system, due to the sluggishness of the beta a dagger" (alpha + gamma(1)) eutectoid reaction, the beta phase can be retained metastably. During quenching, metastable beta alloys undergo a martensitic transformation ...
The effect of alpha-tocopherol on the oxidative cleavage of beta-carotene
(Elsevier B.V., 2000-07-15)
Two cleavage pathways of beta-carotene have been proposed, one by central cleavage and the other by random (excentric) cleavage. The central cleavage pathway involves the metabolism of beta-carotene at the central double ...
The beta(1)-adrenoceptor site activated by CGP12177 varies in behavior according to the estrous cycle phase and stress

Expression of transforming growth factor-beta 1, -beta 2, and -beta 3 in human developing teeth: Immunolocalization according to the odontogenesis phases
(ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2008)
Transforming growth factor-beta (TGF-beta) is a multifunctional growth factor that has several biological effects in vivo including control of cell growth and differentiation, cell migration, lineage determination, motility, ...
Purification of microbial beta-galactosidase from Kluyveromyces fragilis by bioaffinity partitioning

Microstructural Evidence of beta Co(2)Si- phase Stability in the Co-Si System
(SPRINGER, 2008)
The aim of this work was to verify the stability of the beta Co(2)Si phase in the Co-Si system. The samples were produced via arc-melting and characterized through Scanning Electron Microscopy (SEM) and Differential Thermal ...
Solid-phase Petasis multicomponent reaction for the generation of beta-lactams 3-substituted with non-proteinogenic alfa-amino acids
(Elsevier, 2013-07)
An efficient protocol for the rapid generation of libraries of biologically promising b-lactams is described. Key step is a solid-phase based multicomponent Petasis reaction
Quantitative determination of maitenin and 22 beta-hydroxymaitenin in callus of Maytenus aquifolium (Celastraceae) by reverse phase high performance liquid chromatography
(Wiley-Blackwell, 1998-09-01)
Explants of Maytenus aquifolium were induced to form callus and, subsequently, suspension cultures. The isolation of natural products from callus led to the identification of the cytotoxic triterpene quinonemethides, ...
