A general class of zero-or-one inflated beta regression models
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This paper proposes a general class of regression models for continuous proportions when the data contain zeros or ones. The proposed class of models assumes that the response variable has a mixed continuous-discrete ...
A model-based approach to Bayesian classification with applications to predicting pregnancy outcomes from longitudinal beta-hCG profiles
(OXFORD UNIV PRESS, 2007)
This paper discusses Bayesian statistical methods for the classification of observations into two or more groups based on hierarchical models for nonlinear longitudinal profiles. Parameter estimation for a discriminant ...

Extraction of lithium from beta-spodumene using chlorination roasting with calcium chloride
(Elsevier, 2015-02)
Chlorination roasting was used to extract lithium as lithium chloride from β-spodumene. The roasting was carried out in a fixed bed reactor using calcium chloride as chlorinating agent. The mineral was mixed with CaCl2 on ...
Purification, characterization and sequencing of the major beta-1,3-glucanase from the midgut of Tenebrio molitor larvae
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The major beta-1,3-glucanase from Tenebrio molitor (TLam) was purified to homogeneity (yield, 6%; enrichment, 113 fold; specific activity, 4.4 U/mg). TLam has a molecular weight of 50 kDa and a pH optimum of 6. It is an ...
In vitro and in vivo inhibition of Hass avocado polyphenol oxidase enzymatic browning by paeonol, beta-cyclodextrin, and paeonol:beta-cyclodextrin inclusion complex
(Soc Bioscience Bioengineering Japan, 2019-06)
Polyphenol oxidase (PPO) was extracted from Hass avocados and its physicochemical properties were analyzed. The optimum pH and temperature of the enzyme were pH 7.5 and 20°C. This PPO showed a high thermal stability, since ...
