New mathematical modelling for grain size distribution adjustment in concrete
(2019-01-01)
Concrete used in civil engineering is a composite obtained from the combination of coarse and fine aggregates, cement and water, and its cost and quality are normally associated to the proportion of its constituents (ceramic ...
Polymer induced condensation of DNA supercoils
(American Institute of Physics (AIP), 2008-11-14)
Macromolecular crowding is thought to be a significant factor driving DNA condensation in prokaryotic cells. Whereas DNA in prokaryotes is supercoiled, studies on crowding-induced DNA condensation have so far focused on ...
Lamotriginium crotonate and lamotriginium salicylate ethanol monosolvate: The role of solvent molecules in the packing organization
(International Union of Crystallography, 2017-07)
Two lamotriginium salts, namely lamotriginium crotonate [systematic name: 3,5- diamino-6-(2,3-dichlorophenyl)-1,2,4-triazin-2-ium but-2-enoate, C9H8Cl2N5 + - C4H5O2 , (III)] and lamotriginium salicylate [systematic name: ...
Aggregates in the strength and gravity regime: Particles sizes in Saturn's rings
(Academic Press Inc. Elsevier B.V., 2012-08-01)
Particles in Saturn's main rings range in size from dust to kilometer-sized objects. Their size distribution is thought to be a result of competing accretion and fragmentation processes. While growth is naturally limited ...

Influência do empacotamento da areia no desempenho dos compósitos cimentícios
(Universidade Federal de Minas GeraisBrasilPrograma de Pós-Graduação em Construção CivilUFMG, 2018-06-26)
The granulometry of fine aggregates influences the cement composites´ performance and, depending on the used gradation of sand, may enable packaging. In literature, many studies investigate the packaging of fine aggregate ...
Uncoupling the MgATP-induced inhibition and aggregation of Escherichia coli phosphofructokinase-2 by C-terminal mutations
(ELSEVIER, 2008-06-11)
Binding of MgATP to an allosteric site of Escherichia coli phosphofructokinase-2 (Pfk-2) provoked inhibition and a dimer-tetramer (D-T) conversion of the enzyme. Successive deletions of up to 10 residues and point mutations ...
Mechanical and durability properties of recycled aggregate concrete with ternary binder system and optimized mix proportion
(Elsevier Editora Ltda, 2020-01-01)
This study aimed to investigate the mechanical and durability properties of recycled aggre-gate concrete with a ternary binder system and optimized mix proportion. Two concretebatches were developed using a densified mix ...
