Insights into the effect of imidazolium-based ionic liquids on chemical structure and hydrolytic activity of microbial lipase
(2019-07-12)
This work studied the effect of the cation alkyl chain length of 1-alkyl-n-methylimidazolium chloride ([Cnmim]Cl)-based ILs on the activity of Aspergillus niger lipase. First, the lipase activity in the presence of different ...
The effect of land-use changes on the hydrological behaviour of histic andosols in south Ecuador
(2005-12)
The south Ecuadorian Andean mountain belt between 3500 and 4500 m altitude is covered by a highly endemic and fragile ecosystem called paramo. The Histic Andosols covering this regi ´ on have highly developed hydric ...
A conformational switch balances viral RNA accessibility and protection in a nucleocapsid ring model
(Elsevier Science Inc, 2019-08)
Virus from the Mononegavirales order share common features ranging from virion structure arrangement to mechanisms of replication and transcription. One of them is the way the nucleoprotein (N) wraps and protects the RNA ...
Aplicação de um jogo digital e análise de conceitos da teoria cinética dos gases
(Universidade Estadual Paulista (Unesp), 2016-03-04)
Esta pesquisa objetivou investigar se licenciandos em química enunciam e compreendem os conceitos de aleatoriedade e irreversibilidade, presentes na Teoria Cinética dos Gases, por meio de etapas construídas para um jogo ...
A kinetic study of drying of TEOS-derived gels under nearly isothermal conditions
(ABM, ABC, ABPol, 1999-01)
The drying of wet Tetraethoxysilane-derived gels was studied by means of thermogravimetric analysis as a function of the time, from the instant when the samples were placed into a pre-heated oven, kept at 70, 83 and 100 ...

Forest destructuring as revealed by the temporal dynamics of fundamental species - Case study of Santa Genebra Forest in Brazil
(Elsevier B.V., 2014-02-01)
Variation in the composition of the tree population is common throughout the history of a well-preserved forest community, with this natural process maintaining the forest structure and giving rise to ecological processes ...
Conformational Heterogeneity Determined by Folding and Oligomer Assembly Routes of the Interferon Response Inhibitor NS1 Protein, Unique to Human Respiratory Syncytial Virus
(American Chemical Society, 2015-08)
The nonstructural NS1 protein is an essential virulence factor of the human respiratory syncytial virus, with a predominant role in the inhibition of the host antiviral innate immune response. This inhibition is mediated ...
