Estudo da influência do ângulo de hélice em brocas de metal duro na furação de alumínio aeronáutico
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Mecânica - PPGEMecCâmpus São Carlos, 2022-02-23)
The use in machining aluminum alloys offers many advantages: high cutting speed, low cutting forces, minimal tool wear and relatively low machining temperature. When machining aluminum alloys, it is always advisable to use ...
An improved theoretical formulation for Sauter mean diameter of pressure-swirl atomizers using geometrical parameters of atomization
(Elsevier Ltd, 2022-06-01)
This study discusses the development of a mathematical model that is capable of predicting the drop size mean diameter of the spray generated by a pressure swirl atomizer, considering the effects of the liquid's viscosity ...
A strained DNA binding helix is conserved for site recognition, folding nucleation, and conformational modulation
(John Wiley & Sons Inc, 2009-06)
Nucleic acid recognition is often mediated by alpha-helices or disordered regions that fold into alpha-helix on binding. A peptide bearing the DNA recognition helix of HPV16 E2 displays type II polyproline (PII) structure ...
Computational method for the design of wind turbine blades
(Pergamon-Elsevier Science Ltd., 2008-06)
Zeus Diseñador was developed to design low-power, horizontal-axis wind turbine blades, by means of an iterative algorithm. With this software, it is possible to obtain the optimum blade shape for a wind turbine to satisfy ...
Orphan nuclear receptor NGFI-B forms dimers with nonclassical interface
(2007-08-01)
The orphan receptor nerve growth factor-induced B (NGFI-B) is a member of the nuclear receptor's subfamily 4A (Nr4a). NGFI-B was shown to be capable of binding both as a monomer to an extended half-site containing a single ...

Dihedral-angle Gaussian distribution driving protein folding
(2008)
The proposal of this paper is to provide a simple angular random-walk model to build up polypeptide structures, which
encompass properties of dihedral angles of folded proteins. From this model, structures will be built ...
Spin-dependent transport through a chiral molecule in the presence of spin-orbit interaction and nonunitary effects
(American Physical Society, 2016-02)
Recent experiments have demonstrated the efficacy of chiral helically shaped molecules in polarizing the scattered electron spin, an effect termed chiral-induced spin selectivity. Here we solve a simple tight-binding model ...
Phi (?) and psi (?) angles involved in malarial peptide bonds determine sterile protective immunity
Modified HABP (mHABP) regions interacting with HLA-DR?1 molecules have a more restricted conformation and/or sequence than other mHABPs which do not fit perfectly into their peptide binding regions (PBR) and do not induce ...
